Pollution Prevention for Tannery Industry Essay Example

Pollution Prevention for Tannery Industry Paper The assessment identified following pollution prevention opportunities at this facility: recycling the spent chrome tanning wastes, oxidize the sulfide containing wastes, decreasing the volatile organic discharge by changing finishing materials, decreasing water use by batch washing, and using solid wastes from the waste stream as fertilizer. Chromium recycling. This step allows the collection of the spent chrome Nanning solutions, without dilution or contamination, for use in the pickle and tanning process. Since the tannery also tans splits, the spent chrome tanning solution can be used here as well. The tanning of splits results in very good fixation of chromium, so the concentration of chromium in the final effluent should meet effluent regulations. This system results in a saving of about 25 percent in the chromium chemicals used. Solvents. The suppliers of finishing products have developed water-based lacquers with significantly lower volatile solvent contents. These materials are now widely accepted as quality products, and their use is strongly advised. Process Water. In some hide wetting processes there is an opportunity to recycle the final rinses. The final rinse wastewater in this process is compatible with fluids used for the first wetting of the hides. Solid Waste. Elimination of solid leather waste discharges through the use optimizing in reconstituted leather will ease the burden on landfills. Capital Intensive Modifications. Eliminating sulfides from the effluent is very important, as they will corrode pipes, cause objectionable doors, and may cause fatal accidents.

These collected wastes can be placed in a tank and the sulfides oxidized by air with a catalyst. This method is effective and can destroy the sulfide in 4-8 hours. At this point the lime waste, with high BODY and suspended solids, can be used to neutralize the acid wastes that are being continuously discharged. The acid and alkaline wastes from the tanning process will react to produce a expectoration of much of the suspended lids and BODY. This is done with a mixing tank and automatic pH control. Coagulants can also be added at this point. The neutral streams can then flow to a primary clarifier for the removal of suspended solids as sludge. The sludge can be dewatered in a sand bed to more than 50 percent solids for disposal. Although this effluent is somewhat high in BODY, over 80 percent of the pollution load have been removed. The sludge is a good soil conditioner, and if used as such, will eliminate possible high disposal costs. Secondary Treatment. In the future, a secondary treatment system can be added for BODY removal. The secondary system need only be as large as needed for the clarified wastes, and it may consist of a trickle filter, a secondary clarifier, and/ or a filter press. Environmental and Economic Benefits implementation of the suggestions will lead to a number of positive environmental and economic benefits. Chromium recycling will decrease the chromium in the discharge by 80-90 percent. It decreases chromium to less than 3 MGM/l. Costs were estimated at $20,000 (US), savings at $60,000 per year ND therefore payback period of 4 months. The reduction of volatile solvents will decrease VOCE releases to the atmosphere by 60-90 percent. Changes to water usage patterns will decrease effluent volume by 20-40 percent. Elimination of solid leather waste discharges through the use of trimmings in reconstituted leather eases the burden on landfills. This decrease leather waste by 60-80%. Costs were estimated at $1 0,000 (US). Destroy sulfides by air oxidation decreases sulfide wastes by 95- 98 percent. Costs were estimated at $30,000. (US) With primary and secondary treatment, the BODY an be reduced by 75 percent.

World Strruggle Comes to Division essays

World Strruggle Comes to Division essays It is thought that this war that is been ongoing for over a year, began with the assassination of the Archduke Francis Ferdinand; however, many other reasons led to this war. Some occurring reasons date as far back as the late 1800's. Nationalism, militarism, imperialism, and the system of alliances were four main factors that pressed the great powers towards this explosive war. Nationalism is the love of one's country rather that the love of a native region. Throughout the 1800's many national groups that were driven by nationalism tried to unite by governments controlled by their own people. However, this desire to unite all the people of a nation under one government had devastating possibilities in Europe, where one government often ruled many nationalities. This is one important reason for the start of the Great War. Another reason for the start of the war was the practice of imperialism by many countries. Imperialist countries narrowly avoided war many times as they struggled to divide Africa among themselves in the early 1900's. Two of these countries, France and Germany, were on the brink of war several times when the argued about claims to Morocco. Between 1905 and 1911 they settled each argument with a temporary compromise that left one of the two countries dissatisfied. Although imperialism played an important role in starting the war, militarism was even a greater factor. Militarism controlled the thinking of many European Leaders before the war. These leaders thought that only the use of force could solve problems along nations. These leaders also thought that a military strong nation usually got what it wanted, and weaker nation usually lost out. As international rivalries, each nation in Europe made their armed forces stronger and larger. As all these things began to build up the spark that set off the explosion and led to the war was the assassination of Archduke Francis Ferdinand. While the heir to the Austro-...

This type of advancement can be seen in another key industry that is seldom considered for RFID Technological advancements: warehousing. La Scalia et al. (2010) present research that suggests a complex issue with warehousing application that reduces efficiency lies in the Stock Keeping Units. These SKUs have a quantity that is often assumed as opposed to actually quantified which is where RFID Technology can be utilized to advance the information systems and present a more accurate stock keeping database and process for greater warehousing production. Furthermore, RFID technologies are a cornerstone to advancement in operational and supply chain management whereby information accuracy, storage and evaluation is essential to improved efficiency (Ngai, 2009). Without these technologies, Chambers mentions that companies risk falling behind the competition and losing a large share of the market profits.

Comprehensive planning Assignment Example | Topics and Well Written Essays - 1000 words

Comprehensive planning - Assignment Example These are some of the items that bring abut controversy in the agendas of local government. With their widespread significance and usage, it is surprising to see that plans are hardly evaluated against standards of best practice. Despite the centrality in plan making about land use, to the regional and city planning profession, there is a knowledge gap in relation to the quality of produced plans. This may be because of the complexity of the plan’s nature, as well as future orientation which bring together issues, factors, and aspirations from many sources to focus on long term outcomes. The gap is also as a result of unsystematic result integration and lack of evaluation because of the perception that they involve a lot of art, which defy rational analysis. Assessment of Plan Quality New York New York is a metropolitan city that consists of a society that is performance oriented. In such a city, people should be able to judge if their development plans achieve their goals, an d how well the planning process has been conducted. The plan by Robert Moses shaped New York City by providing freeways, parks and bridges systems (Ballon & Jackson, 2007; Caro, 1974). The aims of a profession like regional and city planning include enforcing high practice standards. Good practitioners reflect on their work’s quality and their experience so that they can learn (Meck, 2002). In New York, land use plans help the public to develop sustainable communities that value environmental, social, and economic values balance (Godschalk and Kaiser, 1995). These are the main subject matter elements of the plan, together with guiding land use in the future into configurations that are desirable. It also aims at assisting communities in addressing threats and opportunities, so as to make the best choice among policy alternatives. This planning presentation is clear in its organization. New York land use plan reaches the full planning power because stake holders are educated a bout options and issues, thus helping them to build consensus about visions of the community, thus mediating conflict between change and stability. The community’s participation in the process has helped its citizens in educating their future leaders and networks to resiliently respond to stresses like disasters. New York City Plan also gives the community periodic updates where the community gets an opportunity to assess the progress of their goals, and change in conditions that are important. According to Berke, Godschalk and Kaiser (2006), a good plan has a wide range of power to influence life quality, environmental justice, disaster resistance, economic opportunity, infrastructure costs, transportation efficiency and other aspects that affect community life. The New York plan is very comprehensive in taking into account all these issues. It is community oriented, besides allowing community participation. On the other hand, it fits well into Godschalk and Kaiser Developme nt plan. It was systematically evaluated, to specifically identify the strengths and weaknesses, thus determining its overall quality through democratic determination of instruments and visions. This provided a basis that ensured that it attained

Convey the story Essay Example for Free

Convey the story Essay Heloise and Abelard by James Burger has its place among the most famous biographies that were written about the pair of lovers who lived in Medieval Age, and which is based on the correspondence the two held. It opens a new perspective on the life of the Dark Ages, on its institutions and philosophies, and most of all, on its theology. The lovers who became the victims of the religious age they lived in, that could not admit their love, or any other type of love, for that matter, except religious love. The characters themselves are besides the initiators of free love, the ones who foresee the escape from the too rigid, rule-based religion of the Medieval centuries: â€Å"Let us read after this the famous Colloquy of Erasmus, The Franciscan, and we will find repeated all the essential ideas of Heloise: Christ preached but one religion, the same for layfolk and monks; the Christian renounces the world and professes to live only for Christ, and St. Paul did not preach this doctrine for monks but for everyone; layfolk, even the married, are bound to chastity and poverty quite as much as monks; in short, the only rule binding the Christian is the Gospel. Once she has adopted this course, Heloises frank and direct reason would not let her stop. Carried away by her own logic she was to touch, one after the other, almost all the critical points on which the humanists and reformers of the sixteenth century are so insistent. Why forbid meat to monks? Meat in itself is neither good nor bad. Let us not attach religious importance to things which in fact have none. Nothing counts save what can lead us to the kingdom of God. Let us forget, then, these exterior practices common to truly pious souls and to hypocrites, It is only interior acts that really count for the Christian. The rest is Judaism. † (Gilson, 132) Thus, the point that the story of Heloise and Abelard is trying to make, is that theirs was the one of the most tragic examples of the many failures of the Medieval Age, which persecuted through religion and rigid commandments, trough enclosing monasteries and punishments of all kind, instead of opening the road to what true spirituality means. The touching and tragic story of the lovers impresses because of the nobility of their thoughts and feelings, and also to the spectacular love story, which remains intense throughout their lives. Love is blended with the Christian doctrine, and the lovers try to find a bridge between the two, something that will only be found later in the history or religion, with the advent of humanism. 2. Explain who Heloise and Abelard were. What is their background and upbringing? What brings their paths together? Heloise and Abelard form one of the most famous couples known for their romantic love, so often compared to such immortal stories like that of Romeo and Juliet. However, their story is the real account of a twelfth century couple that lasted throughout the centuries both because of the unusual love story that united them, and also because of the startling sincerity and openness of the letters that favors a clear view of their characters and lives, and of the circumstances of the century they lived in. Pierre Abelard was a well-known philosopher and theologian of the Middle Ages, whose studies have been concerned with mainly with logic and dialectics in the early years, and then with ethics and theology later on in his life. Of the account he himself gives of his early life in the letter addressed to his friend Philintus, we find that in his early youth he discovered his â€Å"natural genius for study†, and became â€Å"smitten with love for books†, so much so that he decided to renounce at once the fortune that father had bestowed on him as his eldest son, to his brothers and to dedicate himself entirely to learning. His passion and ambition to become a great logician soon brought him notoriety inside the circles of scholars, and he stood out as one of the most reputed teachers of his time. It is in the midst of his glory as a philosopher that the event that will change his life forever occurs: he sees Heloise, the niece of a certain Fulbert. She is belongs to a lower social class than he but she is equal in all else to him: she is literate and very learned, perhaps even surpassing him in depth of thought and feeling. All these were unique and very rare qualities in a medieval woman. Abelard concocts the perfect means of making her acquaintance, with a clear intention to conquer her and make her his mistress. He talks to the uncle, and after having offered him a sum of money, he obtains the latter’s assent to instruct his daughter as her teacher. Heloise, who has reason enough to admire him for his knowledge and brilliant mind, soon falls in love with him and becomes his lover, without the slightest resistance. It is here that their fascinating but tragic story actually begins. 3. Who was William of Champeaux? Discuss his influence in the life of Abelard. Why did Abelard achieve both acclaim and notoriety? Abelard has been, because of his originality of thought, in controversy with many of the philosophers of the age, among these, William of Champeaux, who began by being his teacher, but who was soon outwitted in the lectures he gave by his student. This naturally created animosity between the two, and it became even more founded when Abelard started teaching himself, and drew to his side most of the students that formerly had been instructed by Champeaux: â€Å"I put myself under the direction of one Champeaux, a professor who had acquired the character of the most skilful philosopher of his age, but by negative excellencies only as being the least ignorant! He received me with great demonstrations of kindness, but I was not so happy as to please him long; for I was too knowing in the subjects he discoursed upon, and I often confuted his notions. Frequently in our disputations I pushed a good argument so home that all his subtlety was not able to elude its force. It was impossible he should see himself surpassed by his scholar without resentment. It is sometimes dangerous to have too much merit. Envy increased against me in proportion to my reputation. † ( I) Abelard was many times an envied scholar, and later on, he was even accused of heresy for his ideas, by the enemies he always made in his circle. But, nevertheless, he became more and more notorious, because of the originality and novelty of his ideas, and especially because of his passion and ability for logic and argumentation. 4. How do Heloise and Abelard fall in love? What challenges must their relationship overcome? What were the consequences for both Abelard and Heloise? What is transcendent or universal about their love story? Together in the house of Heloise’s uncle, under the assumed masks of teacher and student, Heloise and Abelard begin their love story. As it becomes clear from Abelard’s own confessions in the letters to her, and from the imputations she brings on him, in her turn, the beginning of their of their affair was due more to his lust and incontinence rather than to his feelings for her: â€Å"Was it not the sole thought of pleasure which engaged you to me? And has not my tenderness, by leaving you nothing to wish for, extinguished your desires? Wretched Heloise! you could please when you wished to avoid it; you merited incense when you could remove to a distance the hand that offered it: but since your heart has been softened and has yielded, since you have devoted and sacrificed yourself, you are deserted and forgotten! † (II) Heloise however, seems to have given herself completely to her feelings to him, from beginning to end of their love story. After they remained together for the space of a few months, but their love was son discovered by Heloise’s uncle, who, enraged, demanded compensation from Abelard for his offense against the family honor. Abelard decides to marry Heloise, and when the latter becomes pregnant he sends her away to Britanny, to the care of his sister. The actual situation of the two lovers can not be fully comprehended without placing it in the Medieval context. Thus, it would perhaps seem natural to a modern reader that marriage be a solution for Abelard and Heloise, one that would confer legitimacy on their bond, both from the point of view of religion and from that of moral. However, this was not the case at all, for a few clear reasons. First of all, both Abelard and Heloise were both learned people, with such strict and high spiritual aspirations that they were incompatible with the idea of lay marriage. Abelard wanted for himself the kind of pure life that he admired in Saint Jerome or Seneca, and which would bring him the glory he longed for. For Heloise his glory would have been her glory too, so she was actually the one who withstood all she could the idea of marriage. In the strict sense of the world, according to the Medieval moral and religious laws, Abelard had the right to marry, without losing by this act the right to teach or his clerical dignity. The actual danger was that they, as all Medieval scholars, regarded marriage as a form of weakness and incontinence, that would inevitably and permanently drive a scholar away from his prayers and philosophical inquiries. Marriage was therefore considered degrading, and not a lot better than fornication for the ones who aspired to become theologians, because it had the same consequences – surrendering to sensual pleasures and forgetting one’s duty to God: â€Å"If therefore laymen and pagans have lived thus, without the restrictions of a religious profession, how much the more is it your duty to do so, you who are a cleric and a canon, lest you should come to prefer shameful pleasures to the divine service, lest you cast yourself into the gulf of Charybdis and perish, lest you should destroy yourself in these obscenities to the mockery of the whole world. (III) It is precisely in this conflict between their great passion and their aspiration for spiritual heroism, that the tragedy of Heloise and Abelard begins, even more so, when we consider that the spiritual ideals they tried to attain were not imposed on them from the outside, but were their own, and therefore as powerful as their love. It is this context that makes possible the famous and extraordinary statement of Heloise to Abelard, in which she declares that she would rather be his mistress or his prostitute than his wife: â€Å"You cannot but be entirely persuaded of this by the extreme unwillingness I showed to marry you, though I knew that the name of wife was honorable in the world and holy in religion; yet the name of your mistress had greater charms because it was freer. The bonds of matrimony, however honorable, still bear with them a necessary engagement and I was very unwilling to be necessitated to love always a man who would perhaps not always love me. † (II) As she herself declares it, Heloise believed in the disinteresedness of love, and considered, ahead of the time she lived in, that marriage does nothing to preserve the purity of love, but, on the contrary, makes it the slave of ambition or other advantages that are not love itself. Love is not to be confused with mere life or be put under the same necessities as the latter, as it would happen in a marriage, and this is seemingly what the story of Heloise and Abelard signified: a love that surpassed in intensity and nobility the limitations of simple life: â€Å"You have very justly observed in your letter that I esteemed those public engagements insipid which form alliances only to be dissolved by death, and which put life and love under the same unhappy necessity. ( )With what ease did you compose verses! And yet those ingenious trifles, which were but a recreation to you, are still the entertainment and delight of persons of the best taste. The smallest song, the least sketch of anything you made for me, had a thousand beauties capable of making it last as long as there are lovers in the world. Thus those songs will be sung in honor of other women which you designed only for me, and those tender and natural expressions which spoke your love will help others to explain their passion with much more advantage than they themselves are capable of. † (IV) Heloise already takes pride in their love story as something universal that will be used as a ground for comparison for future couples who will be bound by so great a love. The two loved each other with such great ardor and nobility, that their love is pure in spite of their sin. In spite of Heloise’s noble attitude that can not consent either to the loss of glory by the man she loves or to the degrading of noble and free love by binding it to the hearse of marriage, the two eventually contract a â€Å"secret marriage†, a compromise imposed by Abelard, so as not to lose Heloise but at the same time, to maintain his respectfulness in public. Abelard sends his wife to the monastery of Argenteuil to avoid further rumors about their marriage, already dressing her in the nun habit, without knowing that she will wear it forever afterwards . The climax of these happenings comes with the barbaric act of revenge that Heloise’s uncle commits. He bribes the servants of Abelard and these allow for someone to enter the room of their master by night and castrate him. This terrible and symbolic revenge is perhaps what made the love story between Heloise and Abelard legendary. Afterwards, they both retire in convents, Heloise being the first to put on the veil, at Abelard’s command, who not being able to posses her anymore, shuts her up from the world in his jealousy, so that she might never belong to anyone else. This is perhaps the greatest and incontestable act of love and sacrifice she performs for him, surrendering herself completely, and renouncing the greatest thing for him: not the world, as he thought, but him, the man she loved. Their love becomes transcendental and universal through the very passion that fettered them when they were together, but which also manifested itself in their acts of renouncement.

My Philosophy on Classroom Discipline My philosophy regarding the best way to manage a classroom is through a model of ownership and preventative discipline. In order to accomplish this, the teacher needs to set the tone for the class during the first two weeks of school and never veer from it. During this time, the students will be made aware of my classroom rules as well as what I expect out of each of them on a daily basis. This will create an open atmosphere in which all members of the classroom are aware of their rights and responsibilities. When a child is given the responsibility to make his own decisions, he may not be ready to do it in an appropriate manner. A young adult (age 15-18), on the other hand, is much more willing and able to accept responsibility for himself. In other words, a young child generally needs more structure and guidance whereas a young adult yearns for the opportunity to be treated as an adult. It is very important for my classroom to be a place where individuals are comfortable expressing themselves verbally. I will make it clear to my students that the quality of their learning experience rests primarily on their shoulders. They will be responsible for reading the material, studying it, and synthesizing it regularly. My goal is to make my students want to do the work so that they can be involved in class discussions. I have no problem with trying to actively involve a student who is not participating. If he is not prepared, I will not ...
