Kautilyas Arthasastra: Military Aspects

Kautilyas Arthasastra: Military Aspects CHAPTER I: INTRODUCTION 1. Army has been regarded from time immemorial as one of the essential instruments for the maintenance of a state. Kings, not only in India but throughout the ancient world, maintained well organised and well equipped armies both for the defence and expansion of their kingdoms. History is abounds in instances that whenever any ruler or state neglected the proper maintenance of their armies, unpleasant results in the form of loss of sovereignty or territory have occurred. The study of the organisation and administration of the army of a particular country in a particular period shall always give clues of its basic fabric. The topic under study deals with the role of Kautilyas Arthasastra in organising and administrating large armies and its relevance in todays world armies. 2. Kautilyas Arthasastra had never been forgotten in India and is often mentioned in later literature, sometimes eulogistically and sometimes derisively. But the text itself was not available in modern times until, dramatically, a full text on palm leaf in the grantha script , along with a fragment of an old commentary by Bhattasvamin, came into the hands of Dr R Shamasastry of Mysore in 1904 who was then the Librarian of the Mysore Government Oriental Library. He published not only the text (1909) and an English translation (1915) but also an index Verborum in three volumes listing every word in the text. Subsequently another original manuscript and some fragments, in a variety of scripts, were discovered as well as old commentaries of the text. An another author Dr RP Kangle of the University of Bombay devoted many years of painstaking edition and comparing the various texts and translations. His monumental three volume edition of the Arthashastra was first published between 1960 a nd 1965 with detailed note.[1] 3. Kautilyas Arthasastra is a treatise on artha and sastra. [3]. Artha is an all- embracing word with a variety of meanings in 1.7.6-7 , it is used in the sense of material well being; in 15.1.1 livelihood; in 1.4.3, economically productive activity, particularly in agriculture, cattle rearing and trade ; and, in general, wealth as in the wealth of nations. Arthashastra is thus the science of politics as it is used in 1.1.1 or 1.4.3 .It is the art of governance in its widest sense. The subjects covered include administration; law, order and justice; taxation, revenue and expenditure; foreign policy; defence and war. 4. Kautilyas Arthasastra contains fifteen adhikaranas or books. Of these the first five deal with tantra or the internal administration of the state. The next eight deals with avapa or its relation with the neighbouring states and the last two are miscellaneous in character. The eighth adhikarna or book is concerned with vyasanas, that is, the calamities ,shortcomings or weakness affecting the various prakritis. It is necessary to overcome the shortcomings before any aggressive activity can be undertaken. The ninth adhikarna deals with preparation for war and describe the kinds of troops that should be mobilised for an expedition, the proper seasons for starting an expedition, the precautions to be taken and the dangers to be guarded against before starting and so on . The tenth book deals with fighting, and describes the camping of the army, its march, various modes of fighting, types of battle arrays and other topics.[4]Thus this study shall primarily concentrate on book eight, nin e and ten in particular and other books in general. 5. The Legend K autilya : This mastermind, who could write a definitive treatise on economics and government at a time when large parts of the world was steeped in intellectual darkness? All sources of Indian tradition – Brahmanical , Buddist and jain-agree that Kautilya (also refer to as Vishnugupta in a stanza included at the end of the work) destroyed the Nanda dynasty and installed Chandra Gupta Maurya in the throne of Magadha. The name Kautilya denotes that he is of the Kutila gotra ; Chanakya shows him to be the son of Chanaka and Vishnugupta was his personal name[6] Kautilya then retired from active life and reflected on all that he had learnt during the process of overthrowing Dhana-Nanda. Since he found the earlier works on statecraft unsatisfactory in many respects, he composed his own definitive work presenting his ideas concerning the ways in which a ruler should gain power and maintain his authority. He was way ahead of his times in his thinking and covered every conceivable aspect on th e art of politics and warfare, which could be imagined at the time he lived. For Kautilya, military strategy was an integral part of the science of polity and he made no distinction between military techniques and statecraft. Kautilyas Arthashastra is a practical work which could have been written only by one who had implemented the tactics which he preached. How to form alliances, how to organise and administer them, how to attack a powerful king, how to deal with revolts in rear, what tricks to play on gullible people- there is plenty of evidence in the text to indicate that the author was giving real life answers to every conceivable hypothetical situation. 6. Statecraft and battle craft have changed over the centuries due to the fast changing technology and increasing requirements of human beings. Kautilya a mastermind contributed immensely to the development of the same, his extraordinary arrangement of battle groups in war and administering them during peace keeping all extraneous factors in mind still remains a masterpiece for century armies. CHAPTER II: METHODOLOGY Statement of Problem 7. To study the military aspects as enunciated by Kautilya in Arthashastra with a specific reference to organisation and administration and analyse its relevance for todays armies. Justification of the Study 8. The Legend Kautilya in his renowned work ARTHASHASTRA has dealt with various contemporary subjects which formed the basis of Chandragupta Mauryas rule and victories, in fact there is a general view that Kautilyas Arthashastra deals only with matters of foreign policy and economy. It is seldom realised that a great portion of this book does in fact, deal extensively with matters of military, he indeed consolidated all the prevailing grand strategy and tactics of those times and gave his expert opinion on the subjects, which ultimately led to victories of Chandragupta Maurya , who never lost a single campaign. It thus emerges that the brilliance of Kautilya was not only in diplomacy but also in warfare, but the fact that strikes out is that he was able to lay down methods to organise and manage the armed forces in a vast empire. The concepts of military administration and organisation in war and peace were inadvertently covered and spread out in all the adhikaranas, thus leading for topic of research for bringing forth, integrating and analysing those sublime aspects of organisation and administration which formed the bed rock of administering and organising large armies as of Mauryan empire, and at the same time analyse its relevance for 20th century armies. Scope 9. This study concentrates on the relevance of Kautilyas teachings with regard to military aspects in general and organisational and administrational aspects in detail including the aspects of tactics, strategy. The study aims to focus on aspects, which are still relevant for the better management of a large army like ours. 10. Methods of Data Collection. The information has been gathered from books, journals and the internet. The bibliography of sources is appended at the end of the text. Chapterisation 11. The subject under study shall be covered under following chapters: CHAPTER III : ORGANISATION OF ARMY 12. Chandragupta maintained a large standing army , though he acquired a big army from his Nanda predecessors, he made impressive accretions to its strength, so that it stood at six lakh infantry,30000 horses,9000 elephants and 8000 chariots . An efficient war office supervised this powerful army. Its thirty members were divided into five member boards . The six boards were : (a) Admirality. (b) Transport. (c) Commissariat and Army Service Infantry. (d) Cavalry. (e) Chariots. (f) Elephants. 13. Kautilya had divided the army into four arms i.e Patti or Padati(Infantry), Asva(Cavalry), Ratha(Chariots) and Hast (Elephants) and hence it was named as Chaturangabala or the four limbed army headed by their respective Adyakshas or Superintendents[7]. They had Following roles to play: (a) War Elephants. The king relied mainly on elephants for achieving victory in battles. They were the premium arm of the army and relied on their strength and shock effect to route the enemy from the battle field. They were required to destroy all arms of the service of the enemy and to break his battle formations. Kautilya has laid much emphasis on the use of elephants as a battle winning factor with following functions: (i) Marching in front, making new roads. (ii) Protecting the flanks. (iii) Helping to cross water and climb and descend from mountains. (iv) Breaking up enemys unbroken ranks, trampling enemys army. (v) Causing terror, capturing battle positions. (vi) Destroying ramparts, gates, and towers. (b) The Cavalry. The cavalry being the most mobile arm in the army was used to influence the battle. It was tasked for the following. (i) Reconnoitring battle grounds, camping sites, forests. (ii) Securing level grounds, water supply sources. (iii) Destroying enemies and protecting own supplies and reinforcements. (iv) Extending the range of raids. (v) Assault the enemys battle formation. (vi) Attack the enemy from the rear. (vii) Cut off the enemys line of supply. (viii) Isolate the enemys strong point. (ix) Feign retreat so as to persuade the en to pursue, once the enemy lost its cohesion the cavalry was supposed to turn around and rout him. (x) Restoration of sit by plugging gaps in own def made by enemys assault. (xi) Making the initial attack, penetrating or breaking through (xii) Pursue the defeated en. (xiii) Rallying the troops.[8] (c) Chariots. The war chariots had lost their effectiveness particularly against well trained cavalry, Maurian army retained war chariots as an independent arm, and they were restricted to a single offensive role of launching a charge against infantry and a near static defensive role. The arm lacked versatility and was too sensitive to terrain; it could produce result only under ideal conditions. According to Kautilya the chariots were to act as the mainstay of the formation in offensive and defensive roles. Their main function was to break up the opponents battle formation during offensive operations and repulse the enemy assault own formation and recapture lost ground by counter attack. (d) Infantry. There were primarily two types of infantry in Mauryan times, archers and spearmen and both were employed together. Archers performed the role of close support weapons as well as artillery and spearman carried out close combat. The spearman carried a large shield for protection. Chandragupta Maurya had turned the infantry into large standing force like the other three arms in the service. Infantry was the main fighting arm as it had the ability to fight over all types of terrain during all seasons and both by day and night. They were also used to protect captured grounds. Apart from the tasks mentioned above, the infantry was also supposed to give close support to the other arms ie the Elephants and the Chariots[9]. Organizational Structure 14. Kautilya had emphasised on hierarchal system for administration of army. The structure of the defence forces at the highest levels was as shown below: Commander -in- Chief Senapati(Chief of Defence) Chief Commanders of Chariot Corps Elephant Corps Cavalry Infantry Divisional Commanders 28. The chief of the four wings were subordinates to the chief of defense. Under the Chief Commanders, there were Divisional commanders. There were other officers such as Camp Superintendents who were given specific functions during the march to battle. The structure below the level of Divisional Commanders is specific to battles. 29. Every division of the formation had its own distinguishing trumpet sound, flags and banners, these were be used to signal the commands to the division-dividing themselves in to sections, joining together ,halting, advancing, turning and attacking. Battalion commanders and Divisional Commanders were responsible for moblisation and demoblisation. Secret agents, prostitutes, artists and artisans and retired military officers were kept to watch over the loyalty or otherwise of soldiers. Duties of Defence Officials 30. The Chief of Defence. (a) Qualifications. The chief of defence was suppose to be an expert in the use of all kinds of weapons used in warfare, riding elephants, horses and chariots and he was conversant with the relative strength of the four wings of the army and how to deploy them in battle. (b) Responsibilities. (i) Discipline in armed forces. (ii) Formations. (iii) Strategy and Tactics. (aa) Choose the best time to start an expedition. (ab) Choose the best terrain and the best season for fighting. (ac) Arrange the disposition of own forces (in the light of the enemies array). (ad) Plan the breakup of the enemies rank. (ae) Destroy enemies scattered troops. (af) Besiege and destroy enemy forts. 31. The Chief Commander Of Elephant Corps. Responsibilities were:- (a) Protection of elephants. (b) Construction and Maintenance of stables, stalls. (c) Training of elephants. (d) Assigning tasks to them. (e) Equipping them for war 32. The Chief Commanders Of Other Corps. Responsibilities Common to all were: (a) Knowledge of different type of equipment needed for his wing and use of such equipment in war. (b) Giving appropriate training. (c) Keeping account of equipment and animals under his charge. (d) Maintaining their equipment in good condition and repairing them when necessary. (e) Supervising the work of all employed by him. (f) Maintaining Discipline. (g) Reporting to the king the state of readiness of his troops[10]. 33. Other Commanders:- (a) Commander of the Kings Guard (Antarvamsika). This very high official, who ranked just below the seven highest paid officials including the senapati, must have been an army general, promoted after having held the appointment of director-general of his own arm. He was directly in line for promotion to senapati. He was in the pay scale of 24,000 pannas, in the same scale as the kings chamberlain and the chancellor. His importance was due to his responsibility for the security of the king and other members of the royal family in the palace. There must have been two other officers directly under his command who assisted him in ensuring the safety and security of the king and the royal family. One was the commander of the male guards who guarded the palace and the commander of the female archers who were detailed as immediate guards for the kings person and his personal quarters. (b) Commander of the Marches (Antapala) The antapala was responsible for guarding the borders of the State. For this purpose border posts were established; their primary purpose was a check on entry of enemy agents, undesirable elements, collection of customs duties and control over the entry of foreigners. Kautilya advocates the establishment of only four border posts, one in each direction of the compass. The siting of border posts on naturally defensible terrain is advocated so these must have served a defensive purpose as well. The antapala must have been a military officer, possibly with detachments from the army for the protection of his posts. (c) Durgapala. Durgapala (fort commanders) must have been army officers who also commanded detachments of regular troops which acted as garrisons, Kautilya mentions at least one fortified city or capital of the State which needed a durgapala. In the text, he refers to other forts. sited to take advantage of naturally defensible terrain. Larger States obviously had more than one fort which acted as bases for military operations and offered refuge in case of need. Types of Troops 33. Kautilya lists six types of troops which may become available to a king and examines the relative merits. The troops are maula (standing army), bhrta (local volunteers auxiliaries), serni (organized mercenaries), mitra ( trops of an ally), amrta ( enemy deserters) and atavi ( tribal levies). [11] (a) Maula Troops. These are the standing army of a state composed of soldiers who may have served the kings family for several generations. They are residents of the state and their interest coincides with those of the king. Their loyalty is assured, their weapons, equipments and the animals are the best the state can provide and their motivation and state of training is high. It is however only prudent that a proportion of this force be left behind for the security of the state. Kautilya recommends that around one- fourth of the maula troops be left in the capital. The maula troops should form a large part of an expeditionary force if : (i) The enemys troops are well trained. (ii) The campaign is expected to be difficult and hard. (iii) Other available troops are unreliable. (iv) Surplus maula troops are available after fully meeting the requirements of the capital and the rest of the state. (b) Bhrta troops. These are locally raised volunteers engaged for the duration of the campaign. They are either veterans or first time volunteers, usually trained in the handling of personals weapons. By profession they were either farmers or small traders who decided to take part in a campaign. As natives they have a stake in the security and welfare of the state. Such troops are reverted back to their professions after the end of the campaign. Their employment is recommended if:- (i) The enemy is weak and a large number of volunteers are available. (ii) The campaign is expected to be easy with little actual fighting. (iii) Success is more or less assured by the use of other means like covert operations or diplomatic efforts. (c) Sreni troops. These were trained, equipped and organised bodies of mercenaries under their own leaders who were available for hire to fight for a specified period of time. Their employment is recommended when:- (i) The opposing forces consist of primarily mercenaries. (ii) Much hard fighting is not anticipated. (iii) Sreni troops are available in adequate numbers for the campaign as well as for the defence of the capital. (d) Mitra troops. These are troops loaned for a campaign by an ally. Their utilisation is advocated if :- (i) Such troops are available in large numbers. (ii) A short campaign is anticipated because of good chances of early success of diplomatic moves underway. (iii) To oblige an ally. (iv) It is proposed to deal at first with the irregular part of enemys army, with his allies and his population centres, prior to attacking his main forces. (e) Amrita troops. These comprise enemy deserters and prisoners of war. They are not to be trusted but their employment is recommended if the eventual outcome of battle is of little consequence. (f) Atavi Levies. These were bands of tribesmen from the jungle who join the king under the command of their own chiefs with the primary purpose of collecting loot. These bands and amitra troops are unreliable and Kautilya considers both categories as dangerous as a snake. The above two categories of troops may be employed if:- (i) If they are available in large numbers to attack the enemys cities and irregular troops. (ii) It is proposed to delay the employment of the main force. (iii) It is Politic to get rid of them because their loyalty is suspect. Atavi troops may be employed as guides or to counter the use of similar to levies by the enemy both categorys of troops. 34. An army composed of units recruited from diverse sources and ready to fight for plunder may be an energetic army. On the other hand, an army whose soldiers belong to the same region, caste or profession is a mighty army; it will continue to fight even if its pay is in arrears and there is shortage of food. It shows bravery even in adverse conditions and its loyalty cannot be subverted. 35. A king should make efforts to obstruct the mobilisation of his opponent. His potential recruits should be intercepted and if necessary recruited into own army. Such personnel should however be discharged at the right time but well before the commencement of actual operations. Analysis 36. A close analysis of Organisational structure propounded by Kautilya in his Arthashastra is a sterling resemblance of what is followed in Indian Army with slight modifications. And it is clearly evident that the basic finer intricacies of the organisation remained the same though the gross structure underwent a change keeping latest technological development in mind. 37. Kautilya was way ahead in his times with clear vision and military thinking thus created an organisational structure catering for civil supremacy and ensured effective coordination between various components of the army which is still relevant at large. Chandra Gupta Maurya had a large standing army to manage similar to that of Indian Army and without a sound organisational structure it would have been virtually impossible to achieve victories which he had set for himself. 38. Kautilya had clearly categorised his army into various corps i.e Cavalry, Elephants, Infantry, Chariots etc with a clear division of roles in war, which is very much akin to our present system of various line directorates in our armies. He had also formed clear command and control structure with minimum scope for ambiguity. He had emphasised on Hierarchical system Command and control in armed forces some 2300 years ago which is still relevant in todays times. 39. The organisation of the Maruan army was little different than the one followed in our army today. Though a striking similarity is the presence of the adyakshas that can be related to our line directorate which are too led by a Lieutenant General. The rank structure is not restricted to any arm but common throughout the army. To elaborate, the pattika was a rank not belonging to a particular arm but he commanded elements of all the arms. This helped in better command and control. This also ensured of a clear demarcation of command structure which was irrespective of the arm, this practice is still followed. 40. When coming to appointment of heads of departments, Kautilya had ensured that they had requisite degree of qualifications for tenanting that kind of appointment and had a clear defined standards and roles for all of them, which is still largely relevant in our armies where selection processes ensure that the said officer had undergone necessary courses and has a requisite skills suitable for tenanting that kind of appointment. 41. Kautilya had imposed various degrees of confidence in terms of loyalty and integrity depending upon the community of troops, probably a relevant thing in those times, but in present times it is debatable whether it is relevant or not as for some community specific armies it may hold good but in Indian context, though the Indian army still have pure regiments based on caste system but the pedestal of loyalty and integrity attributed to each community is the same thus this particular thing is not relevant to Indian Army of present times. 42. Kautilya proposed to have a standing core army consisting of officials down to the Pattika and the regular soldiers to be recruited for the period of war. Specialists like elephant riders archers etc were also recommended to be retained as permanent soldiers. Though India has a large standing army which is used both for protection of its borders and for launching offensive. There is no differentiation in the kind of troops used for both the tasks as envisaged by Kautilya. Probably We can have smaller standing army which can be well trained and equipped with the best of the equipment. On the other hand we can have a larger component of Territorial Army that can be mobilised before an operation. The defensive formation can have Territorial Army and some of the regular troops where as the strike formations can be composed of regular troops. This will help in reducing the defence expenditure and the money saved could be better used for equipping and training of the regular troops. CHAPTER IV: ORGANISATI ON OF LAND FORCES IN OPERATIONS Brave men, giving up their lives in good battles, reach in one moment even beyond those (worlds), which Brahmins, desirous of heaven, reach by a large number of sacrifices, by penance and by many gifts to worthy persons- Kautilya 43. Kauilya gives an exhaustive description of how to arrange the land forces for a set piece of battle, starting with positioning various kinds of forces at various echelons of battle field after giving due considerations to planning parameters. War fighting as propounded by Kautilya has an uncanny resemblance to the methodology in practice today. He was a believer of a strong central force along with two wings which can manoeuvre and the importance of reserves. He is perhaps one of the first thinkers to suggest a tactical grouping of forces with a clear cut commander. This helped in easier organisation of the forces as well as downsizing the army when not in need. Tactical Grouping. 44. Grouping of arms for battle at the lowest level has been practised in ancient India since epic times. Kautilya suggested a standard form of grouping of all arms, for the first time ever. The suggested groups corresponds to a remarkable degree with the current practice in modern armies adopted well after WW II . The lowest grouping was at platoon level, a group now referred to as combat team. Because of this remarkable similarity, the modern designations of combat team, combat group and combat command.[12] Each horse was supported by six foot soldiers three of which were archers (Pratiyodhas) and the remaining three were armed with a sword, spear and a shield (Pratigopas) Initially the archers were placed in front so that they could exploit the range of their weapons and as the battle came to close contact, they would recede and the pratigopas would come in front. 45. Patti. Each elephant or a chariot enjoyed the support of five horse groups. This entire group including an elephant / chariot, five horses, 15 Pratiyodhas and 15 Pratigopas formed the lowest tactically grouped sub unit called the Patti. The patti was commanded by a Pattika. 46. Sena. Consisted of ten patties and was commanded by a Senapati or a battle group under a battalion/regimental commander and ten or less senas formed a brigade commanded by a Nayaka. 47. Intervals .There are two sets of intervals or gaps between the files and ranks laid down by Kautilya, one is a narrow gap with the proviso to increase it by double or three times and the other is a larger gap between archers which extends to other arms. It is possible that smaller gaps are for forming up on ceremonial and drill purposes (close order) were archers do not need extended space and larger intervals (open order) for battle information. In a battle formation adopted in an open order the minimum gap between two files of archers was one dhanu(bow) of five hastas(forearm) or 2.5 mtrs, between horses it was three dhanu(7.5 mtrs) and between elephants or Chariots it was five dhanus(12.5 mtrs). The interval between the centre and a wing as well as a wing and its flank was also 12.5 mtr. Kautilya does not indicate the gap to be maintained between ranks but it may safely be assumed that the interval between sub ranks,ie. Within a rank of elephant or chariots, i.e between a sub rank of patiyodhas and a horse would be three dhanus and between ranks, i.e the rare sub rank or padagopas of the front rank and the front sub rank of patiyodhas of the second or centre rank would be five dhanus(12.5 mtrs). These intervals could be increased in accordance with the ground available for battle and the size of the force to be deployed. 48. Reserves. Reserves held an important place in the battle formations as per Kautilya, reserves were directly involved in shaping of the battle field and were placed directly under the control of the king. A firm base was to be established on a suitable terrain approximately 600 -700 m behind the army and it was here that the reserves were placed. The reserve consisted of about one third of the best available troops. The king was advised to be stationed at this firm base after the actual fighting commenced and be in a position to influence the battle by sending reinforcement when and where needed and to make the firm base as a rallying point in case of a reverse.[13] 49. Standard battle formation (vyuha). A standard brigade group was formed for battle is referred to as a standard battle formation or array. Additions and alterations were made to it, according to a formula, in order to accommodate additional troops available for deployment. The standard brigade group deployed five senas each which contained nine to ten pattis; total troops deployed were: (a) Elephants or Chariots : 45 (b) Horses : 225 (c) Patiyodhas(archers) : 675 (d) Padagopas(foot soldiers) : 675 This force of five senas formed up in five groups i.e centre (urasysa) in middle, the right wing (kaksa) and the left wing (kaksa) after an interval of 12.5 mtrs on both sides and after another similar interval the right flank and the left flank (paksa). Each of these groups or senas formed up for battle in three ranks of three elephants each (three patti). Each elephant had three horse groups in front and two behind it with standard deployment as illustrated earlier. Thus making a total of 27 archers a head of each sena. The archers could effectively utilise their long range capability before close contact was made with the enemy and the change over placed them with the spearmen behind the horses, just prior to the two sides engaged in close combat. However in such a deployment the interval between elephants was at around nine dhanus or 22 mtrs which is tactically unsound and out of supporting range of neighbouring elephants , in any case Kautilya places the suitable gap between ele phants at 12.5 mtrs. The only solution seems to be to for

Latin American Hydroelectricity Research :: essays papers

Latin American Hydroelectricity Research Financial Analysis of Latin America Opportunity The following is an illustration of the financial feasibility of a joint venture hydro electricity power plant project in Central America. Estimating the estimated costs of our proposed project, our group chose to use Commonwealth Edison as a comparison. Commonwealth Edison, a subsidiary of Unicom Corp, is used as an assessment of our hypothetical costs of providing electricity for Central America. Using Commonwealth Edison we feel provides a good measure of the validity of estimated costs our corporation would incur. Generally Accepted Accounting Principals (GAAP), used by all U.S. corporations, is the highest standard in the world in determining the validity of a corporation's financial statements. In the subsequent paragraphs, we will demonstrate costs of the joint venture project. Future growth rates in Central America market share for electricity will be projected as well. One of the benefits that our corporation will have in expansion to Central America is a lower cost of capital. A substantially larger pool of investors would provide a larger supply of loanable funds. Having a greater selection of borrowers in the international market will reduce the cost of starting our firm in Central America. Portfolio diversification is another advantage that our firm will attain, in regards to foreign investment in the financing of our project. The projections of the percentage of debt our firm will incur will be discussed in the following paragraphs. In looking at the average debt to equity ratio (D/E) of hydroelectric firms in the U.S., we feel that a 67% debt / 33% equity structure would be feasible to initially launch our firm in Central America. To use a comparison, Commonwealth Edison's plant and equipment assets total $28.245 billion. Com Ed provides electricity for over 6.5 million residents in Chicago, and other segments of Illinois. The total population of Central America - (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Panama, and Nicaragua) total to 35.5 million. Taking account these statistics, plant and equipments costs for our firm providing the Central American region would cost $154.22 billion. Using this cost estimate, we would finance $103.33 billion though new market issuance in the U.S. 30 -year Treasury market. At a $100,000/ per U.S. Treasury bond face amount, we would need to have access to 1.03 million 30 yr bond contracts, at the prevailing market interest rate of 6.

Comparing The Grapes of Wrath and The Power of One Essay -- comparison

Comparing The Grapes of Wrath and The Power of One "Two heads are better than one," it's always been said. But is another person always valuable, or can extra baggage keep an individual from achieving his goals? Both sides can be argued effectively, and both may be true depending on the circumstances. Two historical novels, The Grapes of Wrath and The Power of One, show how two sets of characters took different routes to achieve their goals and how they fared along the way. In The Grapes of Wrath, The Joads, a family of penniless migrant workers, travel to California to look for work, depending on the help of assorted strangers along the way, while The Power of One tells the story of Peekay, a young South African boy growing up alone in a hostile world bent on destroying his chances of success. The books portray very different views on life that are equally valid and convincing; while The Grapes of Wrath is a tale that emphasizes the power that can be achieved in numbers and the consequences of trying to survive alone, Th e Power of One is a testimony to the things one person can achieve when he is forced to depend on and trust in himself only.   Ã‚  Ã‚   The Joads, after they are forced to vacate their farm in Oklahoma, decide to pack all of their belongings and make the voyage to California, where there is supposedly so much work that everyone can make a living. But along the way, they quickly run into trouble. They have little money, an unreliable vehicle, a truckload of people to feed, and miles to go before they reach their destination. The Joads quickly discover something that becomes a major theme throughout the book: cooperating with others to achieve a common goal is sometimes necessary for surviva... ...ss birds banished, their rocky nests turned to river stones"(513;Ch. 24)   Ã‚  Ã‚   Each of these novels, although powerful and influential in its own right, contrasts the other greatly in terms of theme. The Joads in The Grapes of Wrath had to rely on others to obtain their goal, while Peekay in The Power of One struggled to find his way in life completely alone. Though each book is very different from the other, each is an emotional story of life's obstacles and the tremendous human spirit, whether combined or individual, that it takes to overcome them.    Sources Courtenay, Bryce.

The connections t hat Michael develops with Leigh Anne Tuohy are the catalyst for the noticeable change that Michael experiences in relation to feeling a sense of inclusion.Outline at least FOUR key ideas about belonging which are represented in your ORT. * The background experiences within his family, he is one of 7 and doesn’t know his father, while his mum is a drug addict. * The journey to a new environment, connections made with people and the place. * The acceptance of Michael and being welcomed into the Tuohy’s household. * Never judge a book by the cover- Leigh Anne Tuohy accepts Michael for who he is, not what he looks like. * From this Film, we understand a new meaning to helping those who are less fortunate, its all the little things that can have a large impact on the individual.Discuss how the composer has used a variety of language modes, forms, features and structures to represent these key ideas? (At least 12 PEEL or TQE for each) FILM TECHNIQUES * Opening sequence- Show s a playback of Lawrence Taylor snapping Jo Thiemann’s leg in 1985. Leigh Anne Tuohy narrates this scene with the voice over narration and she talks about the importance of the tackle position in football to the moulding of Michael Oher and his astounding protective instincts. The long slow motion shot of Michael Oher introduces Michael to the story, with his town home within the background of the shot. The effect of Flashbacks at the moment when Michael was separated from his mother is to give a short insight as to what Michael Oher had experienced. * On Michael’s journey to the new Christian School that will eventually become a second home for Michael there is a panning shot of Michael in the back seat of the car. Visually we can see that Michael’s body language is conveying a sense of shyness, worry and alienation, as if Michael was in a completely different world.This shot also displays the new opportunity that is about to infold for Michael- new place and n ew opportunity. * The close up shot of Michael observing the ‘new world’ clearly conveys the curiosity and separation form the new town that surrounds him. * Dialogue- â€Å"It’s a brave kid†. â€Å"For wanting to come here. † â€Å"For wanting a quality education†. â€Å"I can tell you most young lads with his background wouldn’t come within 200 miles of this place†.

The automatically judge Michael without knowing who he is as a person. * The use of shot reverse shot of the teacher and Michael whilst in the classroom displays Michael’s unsureness of the new school life and feeling of exclusion from the other children, as well as showing the teachers look of concern and her determination to help Michael. The Film includes a lot of close up shots, in order to convey emotions such as sadness and joy. John Lee Hancock includes close up shots within the film to purposely emphasize the range of emotions that the characters experience, so that it can allow the audience to relate to the position that the characters are in and to help them achieve a re-evaluation of their values, attitudes and beliefs.Discuss similarities between the text â€Å"The simple Gift† composed by Steven Herrick and the film â€Å"The Blind Side† composed by John Lee Hancock. * The relationship that develops between Billy and Old Bill is one that is similar to the relationship between Leigh Anne Tuohy and Michael Oher. To Old Bill, he views Billy as a son and treats him the way that he would treat his own. Leigh Anne Tuohy eventually adopts Michael Oher and the relationship that is developed is one similar to mother and son. Both Billy and Michael both come from a disconnected family in they both had no relationship with their father. Billy and Michael both have experienced a bad lifestyle but then they both start a new journey to a new life, in which they both successfully achieve. Once they have made this journey, a new sense of self identity, acceptance and inclusion is felt strongly and the audience of both stories effectively motivate us to change or re-evaluate our own values, attitudes and beliefs.While this this â€Å"rags to riches† storyline isn't new in the world of Hollywood, it definitely redefines values that have somewhat been lost in our 21st  century society. This film is based on the true story of Michael Oher, who was featured in Michael Lewis' book  The Blind Side: Evolution of the Game. While the screenwriter of The Blind Side, John Lee Hancock, probably took some artistic liberty to make these factual events more heart stirring, whatever the changes may have been, I believe that The Blind Side still remains true to the reality.After wat ching the preview, you already know what is going to happen in the movie; however, the movie truly brings to life Michael Oher's story and goes into depth to show the relationship between Oher and the Touhys. The opening scene of Blind Side shows a playback of Lawrence Taylor snapping Joe Theismann's leg in 1985. Leigh Anne Touhy, played by Sandra Bullock, narrates this scene as she talks about the importance of the tackle position in football to the molding of Michael Oher and his astounding protective instincts.Oher was born to a drug-addicted mother, he had over a dozen siblings and was homeless for years. The Touhy's took Michael Oher, who is played by Quinton Aaron, under their wings and helped him grow into an incredible athlete. For me, there were two incredibly moving scenes. The first was the when Oher told Mrs. Touhy he's never had his own bed before and the second was when Oher called Mrs. Touhy â€Å"Momma† for the first time. At the closing credits, newspaper acc ounts of young men from Oher's part of Memphis that were killed by gang violence were flashed on the screen.There are so many people in this world that are like Michael Oher before he joined the Touhy family. Where might Micheal Oher be today without the help of the Touhys? So, even though you already know how the story ends, The Blind Side is still worth seeing for both the exceptional acting and the moving story of Michael Oher's life. Not only is it just the story of Oher's life though, but it is also a thought-provoking movie that shows that there is still goodwill in this world despite the violence and hatred we see every day.

Why Did People Vote for the Nazi Party

Why did people vote for the Nazi party? ~ Young Unemployed Man 1929 I have decided to vote for the Nazi party. Right now our country is in a depression, and our people are suffering from misery and poverty. Adolf Hitler has promised to make our country a better place by overcoming these problems. His plans for us are so great. He believes in a brighter future for our country. We shall see his dream appearing before our very eyes. In a speech Adolf Hitler gave; he said, â€Å" I’ve made it clear the German nation will be restored only when the German people find their inner strength once more! He believes in our people and our country. He wants the country to become a better place not only for him but also his supporters. He believes he is able to restore our country to its former glory, before World War 2 and the treaty of Versailles. He believes in creating a pure nation, made up of only us Germans. He shows the true weaknesses of democracy. The weaknesses only some people k now of, he shows how unorganized and chaotic their business is.He wants to show us that we have made the wrong decisions in the past and that there can be a new future. A future, which will be filled with hope and discipline. This hope helps us to continue on, and look forward to the future. The promises he made goes out to everyone of all classes, but the most important one he made was to give work to the unemployed. Unemployment is the reason why the country is failing. So when the Nazi party is elected I can finally feed my family again, we can keep warm in the winter and maybe even afford little luxuries.The country will no longer be seen as a disappointment but as a haven, for those people like me, who have nothing but a few scrapes to live off of. The Nazi party has made big promises in which I believe will help our country achieve success. Not only that but it will benefit all of us in the country. All other parties’ promises seem like a disappointment in comparision. Those promises are only a minor achievement but our country wants to create power and purity. â€Å"Heil Hitler! †

Carbohydrates Lab Report Essay

Introduction Carbohydrates are essential in foods as an energy source (starch is the main source of human calories), a flavouring (simple sugars are usually sweet) and as a functional ingredient (sucrose allows ice cream to be soft in the freezer; xanthan gum thickens a low-fat salad dressing). Carbohydrates are a type of macronutrient found in many foods and beverages. Most carbohydrates are naturally occurring in plant-based foods, such as grains. Food manufacturers also add carbohydrates to processed foods in the form of starch or added sugar. As with all our approaches to food ingredients/constituents we will first examine the structure of carbohydrates and then try to elucidate how their structures allow them to function as they do. As their name suggests, carbohydrates basically made up from sugar and water, i.e. Cx(H2O)y, although this ratio is often not strictly true and occasionally other atoms may be present. The carbons are arranges in a chain (most often 5-6 atoms) functionalized with alcohol groups. The terminal carbon either carries either an aldehyde or a ketone functional group. Carbohydrates are classified based on size of base carbon  chain, number of sugar units, location of C=O and stereochemistry. Classifications of carbohydrate are monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharide is the smallest possible sugar unit. Examples include glucose, galactose or fructose. When we talk about blood sugar we are referring to glucose in the blood; glucose is a major source of energy for a cell. In human nutrition, galactose can be found most readily in milk and dairy products, while fructose is found mostly in vegetables and fruit. When monosaccharides merge together in linked groups they are known as polysaccharides. Disaccharide is two monosaccharide molecules bonded together. Polysaccharides are polymers. A simple compound is a monomer, while a complex compound is a polymer which is made of two or more monomers. Disaccharides are polysaccharides – â€Å"poly†¦Ã¢â‚¬  specifies any number higher than one, while â€Å"di†¦Ã¢â‚¬  specifies exactly two. Examples of disaccharides include lactose, maltose, and sucrose. If you bond one glucose molecule with a fructose molecule you get a sucrose molecule. Sucrose is found in table sugar, and is often formed as a result of photosynthesis (sunlight absorbed by chlorophyll reacting with other compounds in plants). If you bond one glucose molecule with a galactose molecule you get lactose, which is commonly found in milk. Starch, glycogen, dextran and cellulose are polysaccharides. Polysaccharides differ not only in the natural of their component monosaccharides but also in the length of their chains and in the amount of chain branching that occurs. Polysaccharides function as storage materials, structural components, or protective substances. Thus, starch ( which exists in two forms: amylose and amylopectin ), glycogen and other storage polysaccharides, as readily metabolizable food, provide energy reserves for cells. Chitin and cellulose provide strong support for the skeletons of arthropods and green plants, respectively. In this experiment those activity that had been carried out means to determine the carbohydrate class of an unknown by carrying out a series of chemical reactions with the unknown and known compounds in each class of carbohydrate such as the Molisch test (general CHO), Barfoed’s test (monosaccharides), Fehling’s test (reducing sugars), Benedict’s test (reducing sugars) and Iodine test (amylose). ACTIVITY 3.1, MOLISCH TEST: A GENERAL TEST FOR CARBOHYDRATES OBJECTIVE: To test the carbohydrate solution MATERIALS: 1 % of carbohydrate solutions( lactose, glucose, starch, sucrose, cellulose, fructose, apple and cabbage ), distilled water(as control tube), concentrated sulphuric acid, Molisch reagent. APPARATUS: Test tubes, test tube holder, dropper, 5ml pipette, glass rod, test tube rack, fume cupboard CAUTION: Molish reagent contains concentrated sulfuric acid , which is toxic and corrosive. It can cause severe burns. Prevent eye, skin clothing, and combustible material contact. Avoid ingesting the substance.If you spill any reagent or acid, immediately notify your laboratory instructor. NOTE: Do not place your thumb over the open end of a test tube when mixing its contents. Your laboratory instructor will suggest ways in which you can safely and thoroughly mix the contents of a test tube. PROCEDURES: 1. 2 ml of each of the 1% carbohydrate solutions that have been prepared is added into one set of labelled test tubes. 2. 2 drops of Molisch reagent are added to each test tube and is mixed well with a clean glass stirring rod. 3. The test tube is inclined. Then 3ml of concentrated sulphuric acid is added slowly and carefully down the side of the tube to form a layer below the sugar solution.( This step is performed inside the fume cupboard ). 4. The resulting solution did not been shook or mixed. 5. The change of the solution is observed and recorded. ( A purple ring at the interface is indicative of a carbohydrate ). 6. The test solutions containing Molisch reagent is discarded into the container provided by laboratory instructor. RESULT: DISCUSSION: Carbohydrates undergo dehydration reactions (loss of water) in the presence of concentrated sulfuric acid. Pentoses and hexoses form five member oxygen  containing rings on dehydration. The five member ring, known as furfural, further reacts with Molisch reagent to form colored compounds. Pentoses are then dehydrated to furfural, while hexoses are dehydrated to 5-hydroxymethylfurfural. Either of these aldehydes, if present, will condense with two molecules of naphthol to form a purple-colored product. A positive reaction is indicated by appearance of a purple ring at the interface between the acid and test layers. Monosaccharides give a rapid positive test. Glucose and fructose are monosaccharide. Disaccharides and polysaccharides react more slowly than monosaccharide. Sucrose and lactose are disaccharide which also gave purple color ring. Starch and cellulose gave slightly purple color because they are polysaccharides. Distilled water gave negative test because it is not carbohydrate. A large apple has around 28-31 grams of carbohydrate. Apple and cabbage contain carbohydrate so that they gave purple ring in this test. CONCLUSION: Glucose, lactose, fructose, sucrose, starch and cellulose all are carbohydrates which give positive test for Molisch test. A sample of distilled water is prepared and tested as the controlling sample. ACTIVITY 3.2, BARFOED’S TEST:A GENERAL TEST TO DISTINGUISH BETWEEN MONOSACCHARIDE AND DISACCHARIDES OBJECTIVE: To distinguish the given carbohydrate solutions as monosaccharides or disaccharides. MATERIALS: 1 % of carbohydrate solutions( lactose, glucose, starch, sucrose, cellulose, fructose), distilled water (as control tube), Barfoed’s reagent APPARATUS: Test tubes, test tube holder, 5 ml pipette, pipette filler, stop watch, water bath CAUTION : Barfoed’s reagent is corrosive and an irritant. If you spill any of the solution on yourself or on the bench, immediately notify your laboratory instructor. PROCEDURES 1. 5 ml of each of the carbohydrate solutions is added into one set of the  labelled test tubes. 2. 5 ml of Barfoed’s reagent is added to each test.  3. The contents of each tube are shook well. All the tubes are placed in an actively boiling water bath at the same time. 4. After the water starts boiling again, the solutions is heated for 3.5 min. ( Timing is important since a false positive test can be obtained for monosaccharides with disaccharide, if the disaccharides are heated for more than 3.5 min thereby breaking down ( hydrolyzing ) to monosaccharides ). 5. During this period, the tubes are observed closely and any change of clarity of the solutions is noted. ( A positive test for monosaccharides is the appearance of a red precipitate of Cu?O within 1 or 2 minutes, if no precipitate forms it indicates the presence of a disaccharide). RESULT: 1% CARBOHYDRATE SOLUTION FORMATION OF RED PRECIPITATE Fructose Yes Glucose Yes Cellulose No Lactose No Sucrose No Starch No Distilled water(as control tube) No DISCUSSION: Barfoed’s test distinguishes monosaccharides from disaccharides. Positive test for monosaccharides is the appearance of red precipitate (Cu2O) within 1-2 minutes. If no precipitate formed, indicates the presence of disaccharide. The red precipitate come from the reaction between the  reduction of copper (II) acetate to copper(I) oxide (Cu2O). RCHO + 2Cu2+ + 2H2O > RCOOH + Cu2Ov + 4H+ The aldehyde group of the monosaccharide which normally forms a cyclic hemiacetal is oxidized to the carboxylate. Glucose and fructose which are monosaccharides show positive result in this test. Reducing disaccharides undergo the same reaction, but do so at a slower rate. So, the timing to heat the sample is set to 3.5 minutes. However, the samples are heated no more than 3.5 minutes to prevent the disaccharide breaking down to monosaccharide. Lactose, sucrose, cellulose, starch and distilled water showed negative result in this test. CONCLUSION: Only monosaccharide will give an immediate red precipitate in Barfoed’s test that is glucose and fructose the other remaining solutions which are cellulose, lactose, sucrose, starch and distilled water do not show any changes. ACTIVITY 3.3 FEHLING TEST: FOR REDUCING OBJECTIVE: To distinguish the reducing sugars and non-reducing sugars MATERIALS: 1% of carbohydrate solutions ( glucose, fructose, cellulose, lactose, sucrose, starch ), distilled water(as control tube), Fehling solution A ( 69.28 grams copper (II) sulfate pentahydrate dissolved in 1 litre of distilled water), Fehling solution B ( 346 grams Rochelle salt ( potassium sodium tartrate tetrahydrate) and 120 grams sodium hydroxide in 1 litre of distilled water) APPARATUS: 5 ml pipette, test tubes, test tube holder, test tube rack, pipette filler, stop watch PROCEDURES: 1. 5 ml of carbohydrate solutions is added into one set of test tubes. 2. By using different glass pipettes, 5 ml of Fehling A and 5 ml of Fehling B are added into each test tubes. 3. The solution is heated in a boiling water bath for 5-10 minutes. 4. Red brick precipitate is formed for positive results. 5. Changes in test tubes are recorded. RESULT: Samples Result Lactose Positive-red brick precipitate Glucose Positive-red brick precipitate Fructose Positive-red brick precipitate Starch Negative-no changes Distilled water Negative-no changes Cellulose Negative-no changes Sucrose Negative-no changes DISCUSSION: Fehling’s solution is used to test for the presence of a reducing sugar. Fehling’s solution was based on the aldehyde or ketone groups in the sugar structures. A sugar is classified as a reducing sugar only if it has an open-chain form with an aldehyde group or a free hemiacetal group. the presence of aldehydes but not ketones is detected by reduction of the deep blue solution of copper(II) to a red precipitate of insoluble copper oxide. Fructose, glucose and lactose show positive result in this test. All monosaccharides are reducing sugars. Many disaccharides, like lactose, also have a reducing form, as one of the two units may have an open-chain form with an aldehyde group. However, sucrose, in which the anomeric carbons of the two units are linked together, are non-reducing disaccharides since neither of the rings is capable of opening. Polysaccharides (sugars with multiple chemical rings) are non-reducing sugars. Polysaccharides have closed structures, which use free atoms to bond together their multiple rings, and take a much longer time to be broken down. So, starch and cellulose which are polysaccharides have negative result in Fehling’s test. Distilled water is not reducing sugar also shows negative result. CONCLUSION: Fehling test is the common test which is used to determine the presence of reducing sugar. Fructose, lactose and glucose are reducing sugars which give brick red precipitate after the solutions are heated. ACTIVITY 3.4 BENEDICT’S TEST: FOR REDUCING OBJECTIVE: To test for reducing sugars MATERIALS: 1% of carbohydrate solutions ( glucose, fructose, cellulose, lactose, sucrose, starch ), 3M hydrochloric acid (HCl), Benedict’s reagent, distilled water APPARATUS: Test tubes, test tube holder, test tube rack, 5 ml pipette, pipette filler, dropper, stop watch, water bath PROCEDURES 1. 5 ml of Benedict’s reagent and 2 ml of carbohydrate are added to a test tube and each tube is shook thoroughly. 2. All the tubes are placed in a boiling water bath at the same time. The solutions are heated for 5-6 min. 3. Any changes in color, in the transparencies and in the formation and color of any precipitate are observed and recorded. 4. Later, 4 drops of 3M HCl are added to 5 ml of 1 % sucrose solution and is heated in the boiling water bath for 5 min. 5. 1 % starch solution is treated in the same way but the heating period was extended to 25-30 min. 6. 1-2 ml of each of solution is applied with Benedict’s test in the same manner as before. 7. The results are compared with those obtained without acid treatment. RESULT: Sugar solution Result of colour of the solution Starch Light blue Lactose Brick red precipitate are formed Fructose Brick red precipitate are formed Sucrose Light blue Cellulose Light blue + white precipitate Glucose Brick red precipitate are formed Distilled water Light blue Sucrose + HCI Brick red precipitate are formed Starch + HCI Light DISCUSSION: The Benedict’s test is used to detect the presence of reducing sugars (sugars with a free aldehyde or ketone group) such as glucose, fructose and lactose. All monosaccharides are reducing sugars; they all have a free reactive carbonyl group. Some disaccharides have exposed carbonyl groups and are also reducing sugars. Lactose which is disaccharides also called reducing sugar as it has the exposed carbonyl groups. Other disaccharides such as sucrose and starch are non-reducing sugars and will not react with Benedict’s solution. Benedict’s reagent is a mild oxidant with CuSO4, Cu (II) sulfate, as one of the reagents. In the presence of a reducing sugar, the blue solution of Cu (II) or Cu+2, is changed to a brick red/brown precipitate of Copper (I) or Cu+1 oxide,Cu2O. If there a small or large amount of the reducing sugar present, the color would range from green to brick red respectively. RCHO + 2Cu2+ + 4OH- > RCOOH + Cu2O + 2H2O Sucrose indirectly produces a posit ive result with Benedict’s reagent if heated with dilute hydrochloric acid prior to the test, although after this treatment it is no longer sucrose. The addition of  HCl hydrolysed the non-reducing sugar, as it split it up into its component monomers. The monomers are reducing sugars which gave the positive result on the second reducing sugar test. The acidic conditions and heat break the glycosidic bond in sucrose through hydrolysis. The products of sucrose decomposition are glucose and fructose, both of which can be detected by Benedict’s reagent, as described above. This same goes for starch. But since starch has larger component compare to sucrose so it took a longer time to hydrolyse. That the purpose of heat it in longer time compare to sucrose. Without the addition of acid to sucrose solution, starch solution, the test given is negative. The solutions remain clear blue after the addition of Benedict’s reagent and heating. Tap water is used only to show the example of negative result of Benedict’s test. Thus it will not show any changes compare to the carbohydrates. CONCLUSION: Benedict’s test is the common test which is used to determine the existence of reducing sugar. Fructose, lactose, and glucose are reducing sugars which give positive test. Starch and sucrose are non reducing sugars which give positive results after adding hydrochloric acid. ACTIVITY 3.6, IODINE TEST: FOR POLYSACCHARIDES OBJECTIVE: To test for polysaccharides MATERIALS: 0.01M iodine, 0.12M KI , 1% carbohydrate solutions (cellulose and starch) , distilled water APPARATUS: Test tubes, test tube rack , dropper. PROCEDURE: 1. Few drop of 0.01M iodine in 0.12M KI added to 1% starch and cellulose solutions. 2. Any changes to the colour are observed. RESULT: 1% CARBOHYDRATE SOLUTION COLOUR OBSERVED Starch Vivid blue Cellulose Yellowish brown DISCUSSION: Starch gives positive result in Iodine test as the color of solution change from yellow to dark blue. The immediate formation of a vivid blue color indicates amylose. Vivid blue coloration forms due to the polyiodide complex formed. Cellulose is derived from D-glucose units, which condensed through beta(1->4)-glycosidic bond. This give cellulose to be a straight polymer therefore, it can’t coil around iodine to produce blue colour as starch does. Only starch gives the color of vivid blue, this is because it contains amylase. The iodine molecules slip inside of the amylase coil. The amylose, or straight chain portion of starch, forms helices where iodine molecules assemble, forming a dark blue color. CONCLUSION: The Iodine test is used to test for the presence of starch. Starch is a type of polysaccharide carbohydrate which is made up of amylose and amylopectin. It is one of the main sources of carbohydrate and present naturally in plant. Amylose in starch form dark blue complex with iodine. ACTIVITY 2.2 SOLUBILITY AND DIGESTIBILITY TEST SOLUBILITY TEST OBJECTIVE: To test the solubility in hot water and digestion by amylase. MATERIALS: 5g of starch, 5g of cellulose, distilled water APPARATUS: Test tubes, test tube holder, glass rod, test tube rack, fume cupboard, 2 centrifuge tubes, analytical balance, cylinder, graduated pipette, pipette filler, 2 evaporator dishes. PROCEDURE: 1 5 g of starch is measured and put into a centrifuge tube;  2 40 ml of distilled of water is measured and poured into the same centrifuge  tube; 3 Step 1 to 2 is repeated by replacing the starch with cellulose; 4 Both of the tubes are heated: the tube containing starch is heated for about 2-3 minutes whereas the tube containing cellulose is heated for about 10 minutes; 5 After heating, both of the content of the tubes are allowed to cool down slightly; 6 The tubes are put into a centrifuge with 3500 rpm for 10 minutes; 7 Empty weight for both of the evaporator dishes is measured; 8 5 mL of the supernatant from both of the tubes is pipetted and poured into two separate evaporator dishes; 9 The evaporator dishes are left in the oven overnight 10 The weight of the evaporator dishes is measured again. 11 The solubility results are recorded and tabulated. RESULT: Solubility (%) = Weight of dried supernatant (g) Weight of the dried carbohydrates (g) For starch, solubility (%) = 0.0093g 50.0023g = 0.01860 % For cellulose, solubility (%) = 0.0010g 50.0027g = 0.002000 % Carbohydrates Weight of dry carbohydrates (gram) Weight of dried supernatant (gram) Solubility (%) Starch 50.0023g 24.8768g- 24.8675g= 0.0093g 0.01860 Cellulose 50.0027g 21.2150g- 21.2140g= 0.0010g 0.002000 DISCUSSION: In this activity, the solubility is defined as the percentage ratio of the weight of dried supernatant to the weight of the dry starch. Solubility can be interpreted as the amount of the dissolved compound that is present in the test solution. From the calculations done, we can see that starch, with a percentage of solubility at 0.01860 %, whereas cellulose have 0.002000 %. Starch and cellulose are two very similar polymers. In fact, they are both made from the same monomer, glucose, and have the same glucose-based repeat units. Since the sugar molecules contain the hydroxyl group or –OH, Thus it can form hydrogen bonds with water molecules, which makes it soluble in water, but only to a limited extent. However, the glucose units in starch are connected by alpha linkages while the glucose units in cellulose are connected by beta linkages. In starch, all the glucose repeat units are oriented in the same direction. But in cellulose, each succesive glucose unit is rotated 180 degrees around the axis of the polymer backbone chain, relative to the last repeat unit. Although cellulose contains hydroxyl groups too, but most of them are hydrogen-bonded to each other when the microfibrils stack together, which accounts for the strength of cellulose fibers. There’s less free hydroxyl groups that can hydrogen bond with water molecules, other than those hydroxyl groups that’s present at the end of each cellulose chain, which causes the cellulose to be less soluble in water when compared to starch. CONCLUSION: Although both starch and cellulose are complex carbohydrates, which have large molecular weight size, significantly reducing their affinity for water, but the hydroxyl groups that exist in the monomers itself actually contributes to their insignificant solubility. However, the solubility will increase when these complex carbohydrates are broken down into its monomers where the hydroxyl groups can form hydrogen bonds with other water molecules easily due to the reduced molecular weight and size that affects the affinity for water. DIGESTIBILITY TEST OBJECTIVE: To determine the digestibility of complex carbohydrates MATERIALS: Starch powder, cellulose powder, enzyme amylase, benedict’s solution, distilled water APPARATUS: 2 centrifuge tubes, measuring cylinder, analytical balance, pipette fillers, graduated pipettes, 2 droppers, 5 test tubes. PROCEDURE: 1 5 g of starch is measured and put into a centrifuge tube;  2 40 ml of distilled of water is measured and poured into the same centrifuge tube; 3 Step 1 to 2 is repeated by replacing the starch with cellulose; 4 Both of the tubes are heated: the tube containing starch is heated for about 2-3 minutes whereas the tube containing cellulose is heated for about 10 minutes; 5 After heating, both of the tubes are allowed to cool down slightly; 6 5 mL of starch is pipetted into a test tube;  7 Step 6 is repeated using a different test tube but a drop of amylase is dropped into it; 8 5 mL of cellulose is pipetted into a test tube; 9  Step 8 is repeated using a different test tube but a drop of amylase is dropped into it; 10 5 mL of distilled water is pipetted into the last test tube, and a drop of amylase is dropped into it; 11 20 drops of benedict’s solution is dropped into five of the test tubes; 12 Any changes occurred is recorded and tabulated. Result Samples Colours of the solutions Benedict’ s test 5 g of starch blue Negative 5 g of starch with amylase Brick red precipitate is formed Positive 5 g of cellulose blue Negative 5 g of cellulose with amylase blue Negative Distilled water with amylase Blue Negative DISCUSSION: Amylase is one of the many members of a class of enzyme, hydrolases, that catalyze the hydrolysis of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules). Two categories of amylases, denoted alpha and beta, differ in the way they attack the bonds of the starch molecules. Alpha-amylase is widespread among living organisms. In the digestive systems of humans and many other mammals, an alpha-amylase called ptyalin is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine. In the experiment, the test tube that contains only distilled water served as a control for this experiment. As for the test tubes that contain starch and cellulose without the amylase, they give a negative result for Benedict’s test, because for starch and cellulose, since both of them are complex carbohydrates, thus they have very few carbonyl groups which contribute to the compound’s reducing properties. Starch is a non-reducing sugar which shows negative result in the Benedict’s test. As for the test tube that contains starch and cellulose with the addition of a drop of enzyme, amylase, the test tube with starch gives a positive result, but not the test tube with cellulose. As we all know, enzyme amylase can only catalyzes the breakdown of starch into simpler sugars, but not cellulose. Cellulose only digested by cellulase enzyme. It is impossible for human digestive enzymes to break the glycosidic bond. Therefore, only the test tube containing starch treated with amylase gives a positive result for the Benedict’s test. CONCLUSION: Enzyme is a highly specific catalyst which can only converts a specific set of reactants into specific products. Amylase only hydrolyze the starch but not cellulose. From here, we can say that the human digestive system would not be able to digest the cellulose, because our digestive system only contains amylase, and not cellulose. Therefore in the perspective of a  human, we can conclude that the digestibility of starch is higher than cellulose, provided that the enzyme amylase is present.

Advantages And Disadvantages Of The Prototype Model Information Technology Essay

Advantages And Disadvantages Of The Prototype Model Information Technology Essay This is a better system for consumers, because consumers have a natural tendency to change their mind in determining the requirements and methods of systems development to support user preferences. Because the methodology of the work system model is provided, consumers get a better understanding of the system being developed.   Offences can be detected early as well as system side mode.   ready to respond more quickly to the user a better solution. The job even more quickly and efficiently if the expander will collaborate further on the status of specific functions and develop the necessary adjustments in time for integration Prototype Model  Disadvantages Directing the implementation and how to build and improve systems. In practice, this methodology can improve the complexity system as the system can be expanded beyond the scope of original articles. The integration can be very difficult. STEPS: There are several steps in the Prototyping Model: The new system requirements de fined in sedentarily possible.  This usually involves interviewing number of users representing all departments and aspects of the systems. An original design made for the new system. A first prototype of a new system built from the original design.  This is usually a scale-down system, and an estimate of the final product characteristics. The overall consumer evaluate the first prototype, registered the strengths and weaknesses, what to add, and what do you off.  Expanders collect and analyze comments from users. The first prototype was modified based on comments provided by the user, and the prototype of both the new system was built. The second prototype is evaluated in the same way as the first prototype.   Previous steps of iteration are needed, until the user is satisfied that the prototype of the desired end product. Final system is built based on the final prototype.   Final system is actually measured and tested.  Conservation of the routine is done continuously to prevent large scale failures and to minimize downtime. Prototyping consists of the following steps: †¢ Requirements Definition / Collection.  Similar to the phase conceptualization Waterfall Model, but not exhaustive.  The information collected is usually limited to a subset of the complete system requirements. †¢ Design.  After the initial layer of requirements information is collected, or new information is collected, it quickly developed into a new or an existing design to be folded into a prototype. †¢ Prototype Manufacturing / Modify.  Information from design to prototype quickly wound up.  This may mean loss / alteration of information sheets, coding, or modification of any coding. †¢ Evaluation.  The prototype presented to the customer for review.  Comments and suggestions collected from customers. †¢ Refinement of prototype.  The information collected from customers digested and refined prototype.  The flourish of the revised pr ototype to make it more effective and efficient. †¢ Implementation of the System.  In most cases, this system is rewritten once the need to understand. Types: Prototype Models Types There are four types of Prototype Models based on their  development  planning: the Patch-Up Prototype, Nonoperational Prototype, First-of-a-Series Prototype Selected Features Prototype. Patch Up Prototype Types of prototype models to encourage cooperation of different developers.  Each expander will work on specific parts of the program.  After everyone has done their part, the program will integrated each other until the new program.  Patch Up The prototype is a model of rapid development.  Type model of software development requires a strong project manager who can oversee the development of this program.  Manager will control the beam of work and ensure that no crutch overlapping different functions of the developers.
