Whats Love Got To Do With It; Everything! :: essays research papers
What We Talk About When We Talk About Love An excerpt from Readers Digest August, 1997, submitted to Laughter, the Best Medicine, by Adam Christing. A lot of people wonder how you know if you really in love, says comedian Ronnie Shakes. Just ask yourself one question: Would I mind being financially ruined by this person? If you really look at this statement, it is invariably the truth. When it comes to love, money makes no matter, be it past, present or future. Love is love, and nothing can stand in its way. In the following pages I will be discussing Raymond Carvers short story, What We Talk About When We Talk About Love. It is a story that explores all types of love, jealous, brutal, physical and spiritual. Written in 1981, it is very contemporary in its style and its meaning can be applied easily to everyday life. Only love that is true in your heart is love, the rest are other emotions sublimated into love. With this in mind, we should look at people around us, people who are in love. Ask to yourself, Why are they in love?Ã Then, ask yourself, How are they in love? It may be surprising, but the answers to these questions can be surpassingly different. Only when they are the same will the love be true. What We Talk About When We Talk About Love, is set in a house somewhere in Albuquerque NM, some time in the afternoon or early evening, and going into night. As previously stated, the story was written in 1981, and it appears to set in the same time. Two couples are sitting around the kitchen table, drinking gin, and talking, talking about love and the many forms it takes. Teresa (Terri) gives a detailed description of a brutal love she had with her ex-boyfriend, and how he beat her. Mel, Terris husband, gives us his feeling for his ex-wife, and how he loves his kids, that she has custody of. Jealousy, is the love he has for her, she has his children, and he wishes her dead, so he could have custody. Finally, the love they all agree as the universally truest love, the spiritual love, is shown by an elderly couple involved in a bad accident. Both of them refuse to die, until they can be assured the other will be all right. In the very beginning of the story, the two couples are sitting around drinking and talking. As their conversation goes on it develops into one of love. This passage marks the first of several types of love, and gives us an intuitive

Mrf Tyre Suggestions
EXECUTIVE SUMMARY 0. 1 0. 1. 1 GENERAL Nylon Tyre Cord: Nylon tyre cord is made from high tenacity continuous filament yarn by twisting and plying. There are two major types of nylons used as tyre cord, i. e. nylon-6 and nylon-6,6. The properties of nylon-6 and nylon-6,6 vary marginally and are controlled by the manufacturing process, type of stabilisers and additives used. In India only nylon-6 is produced commercially for tyre cord. Thetypesofnylon-6tyrecordusedinIndiaare840/2,1260/2,1260/3, 1680/ 2 and 1890 / 2 where number indicates denier of ply / no. of plies in the cord.The denier per filament is 6. 0. 1. 2 Tyre Cord: The other materials used as tyre cord are cotton, rayon, polyester, fibre glass, steel,aromatic polyamides. Each of these materials has its own merits and demerits. The major criteria for acceptance of any material in tyre are its tensile strength, dimensional stability, durability, thermal stability, hysteresis and adhesion. Tests and actual application conditio ns have shown that although other cord materials meet one or more specific requirements, nylon by and large meets the desirable requirements for almost all the performance criteria. . 1. 3 Tyres: The tyre cord fabric provides the tyre its fundamental properties such as shape, size, load carrying capacity, abrasion resistance, fatigue resistance, etc. A tyre is a composite of cord and rubber. There are three varieties of tyres viz. bias-angle tyres, radial tyres and bias-belted tyres. They differ in the way the tyre fabric plies are laid inside the tyre. 0. 1. 4 Manufacturing Process: The manufacturing process for nylon-6 tyre cord can be broadly divided into following production steps: (a) Polymerisation of caprolactam to manufacture nylon chips. (b) Extraction and drying of chips. (c) Melt spinning of chips to manufacture nylon tyre yarn. (d) Preparation ofcordfrom tyre yarn by twisting and plying. (e) Recycling of nylon-6 waste. 0. 1. 5 Polymerisation: Nylon is made by polymerisat ion of caprolactam with certain additives like amino acids and dicarboxylic acid salts and certain heat stabiliser such as copper based organic compounds. The polymerisation process involves ring opening polycondensation and polyaddition reactions. All the three polymerisation reaction steps are equilibrium reactions.A typical process of polymerisation of nylon can be either a batch or a continuous process. The continuous process, developed after the batch process was commercialised, offers simplicity of design, ease of operation and control and high capacity. An optimal polymerisation process would involve two stages, wherein, the first stage involves pressure at high initial water concentration. In the second stage a rapid transition from high water content to a low water content is achieved by release of pressure and subsequent application of vacuum. Industrial grade nylon-6 with relative viscosity 3. 2 to 3. has higher degree of polymerisation compared to textile grade nylon-6 w ith relative viscosity 2. 2 to 2. 6. 0. 1. 6 Extrusion and Drying of Chips: The nylon chips are washed to remove water soluble impurities and then dried. The process maybe batch or continuous. 0. 1. 7 Melt Spinning: The polymer chips are melt in extruder. The molten polymer is then spun through a spinnerette. The molten filaments are quenched or cooled by a laminar flow of air. The spin finish is applied on filament and then wound on spin bobbins and drawn to make tyre yarns. In the conventional process, the spinning and drawing was done in two steps.In the spin-draw process, a step is reduced compared to 2-step conventional process. As a consequence, some sources of process disturbances are eliminated which results in improved yarn uniformity. 0. 1. 8 Preparation of Cord: Nylon tyre yarns are then twisted in S or Z direction and plied having 2 or 3 plies to form a tyre cord. 0. 1. 9 Recovery of Nylon-6 Waste: Depending on the quality of waste, any of the following method may be use d for recycling of nylon waste. Direct use of fibre waste RegrannulationPolymer Powderi) without melting ii) with melting. i) deploymerisationandfilteration i) precipitation from solutions Recovery of caprolactam by deploymerisation. Recovery of amino caproic acid. The first three processes require relatively purer and undegraded form of waste. Amongst the last two, caprolactam recovery is mostly adopted by Indian industry due to ease of purification of recovered caprolactam. 0. 1. 10 Raw Materials, (Catalysts, Additives, Spin Finish Etc. ): For nylon-6, the only major raw material required is caprolactam. Water is required as an initiator for ring opening during polymerisation. Nitrogen gas is required for blanketing, drying and conveying of polymer. 0. 1. 1 Additives/Catalysts: Aminoacids and diamine dicarboxylic add salts which provide water on condensation have been found to be useful for enhancing the rate of polymerisation. 0. 1. 12 Stabilisers: Nylon is susceptible to degrada tion by Lght, heat, oxygen etc. To make it suitable for the purpose of tyre cord, stabilisers are added. The light stabilisers used are manganous chloride + hypophosphorous add and imidazoles. Diphenylamine and acetone condensates give excellent resistance to heat. Copper complexes as halides, acetate, phosphates, salts of higher fatty adds like stearates, palmitates, laurates, etc. re quite effective as heat and light stabilisers. Spin Finish: The functions of spin finishes are to reduce friction to get proper filament cohesion and to provide static protection. Lubricants used to reduce friction are usually mineral oils, fatty glycerides. The antistats used to provide static protection are surface active organic compounds. In case of nylon tyre cord, where molten polymer is drawn in yarn stages and fabric is dipped at a very high temperatures (upto 210à ° C), preference has been towards the use of non-fuming type spin finishes. 0. . 14 Major Capital Equipments: The major capital e quipments for each section of the plant viz polymerisation, spinning, cord making and caprolactam recovery are listed in para 1. 7. 0. 1. 15 Development of Technology: The developments in technology canbe grouped into the following: Product development. Development in the polymerisation process. Development in extraction and drying. Development in melt spinning process. A. Product Development: Till 1937, cotton used to be the only tyre cord material throughout the world. Thereafter rayon became popular.Subsequently with the advent of synthetic fibres, the use of nylon increased, which continues to be used in both the developed and developing countries, Other materials used are polyester introduced in 1962, fibre glassin 1967 and steelin 1970. NTC was earlier spun as 210 d-yarn and then plied to give 840 d tyre cord. With the development of technology, now, directly 840 d yarn can be spun and then plied to get denier ranges of 1260, 1680 and 1890 tyre cord. The denier per filament ha s however remained^ fe though some attempts have been made to use 8 deniers filaments also. It has been possible to increase tenacity from 8 gpd to9. gpd. B. Developments in Polymerisation Process: In early process, a relatively crude batch autoclave reactor was used for polymerisation. The V K tube reactors for continuous polymerisation, were introduced during early 50s. Initially, V K tube reactor had capacities of 1. 5 TPD which has now been increased upto 40 TPD. Over a period of time, number of stages of polymerisation has also increased from one to seven. Continuous developments have also taken place for modifying the design of reactors to achieve plug flow condition and uniform flow and temperature gradient, improve residence time, conversion rate and quality of products.The details of some such developments are discussed in para 1. 8. C. Developments in Extraction and Drying: In this area also, batch type extraction and drying process have been replaced by continuous process es. Chips are now stored in S. S. tanks and conveyed pneumatically to spinning section. D. Developments in Spinning Process Melting of chips was done by oil heated grids in the pre-world war era, then by electrically heated grids. In the late fifties a short barrel screw extruder was introduced which is now replaced by longbarrel extruder.Another development is increase in the spinning capacity by increased number of spinning positions and also increased number of ends per spinning position. Other improvements are in yarn solidification and quenching process, spin finish application methods etc. During late seventies, the spin-drawn process was introduced to get higher productivity and better product. During the same period, high speed spinning with take up speed of 3,000 to 4,000 mtrs/min (as compared to upto 1500 mtrs/ min in case of conventional process) was developed. 0. 2 . 2. 1 STRUCTURE OF INDUSTRY AND STATE OF THE ART: Structure of Industry: Licensed and Installed Capacity T he total licensed and installed capacity of NTC in India at present is around 29,500 TPA and 22,500 TPA respectively, as per the details given in para 2. 1. 10. LOI / IL have been issued which cover capacity of 54,200 TPA. Production: The production of NTC in India started in 1971 with 595 tonnes and increased to around 23,600 tonnes in 1985. NTC has replaced rayon tyre yarn as tyre cord yarn and market share of NTC at present is 75%.Capacity Utilisation: The licensed and installed capacity is based on certain denier while production is of different deniers and the product-mix of all manufacturers varies depending on market requirements. However, the overall average capacity utilisation ofNTCinIndiahasbeenaorundl05%duringthelastfiveyears. Distribution of Units: Active NTC manufacturers are public limited companies spread almost all over India with average capacity of 4000 TP A. Performance of Industry: The production, sales, net fixed assets, net worth of all the NTC manufacturers s how an upward trend.There is a general growth rate of 20% per annum on sales turnover during last five years. Import/Export: Import of NTC increased from 1677 tonnes in 1980-81 to 5295 tonnes in 198384 The price of NTC at international level is just half of the price in India. This is mainly due to high cost of raw materials, higher conversion costs due to old technologies and small size of Indian plants as compared to the plants in developed countries. Due to this, export of tyre yarn from India is negligible. Sources of Technology and their Broad Performance: Unitika, Japan has supplied technology and plant to three out of five Indian manufacturers of NTC.The other two manufacturers started with imported plants. The details of these collaborations are given in para 2. 15. 2. Performance of all the collaborations is satisfactory. Though, indigenous technology comprising of batch polymerisation and conventional spinning process have been developed, none of the NTC plants in India ha s yet started with such indigenous technology. The latest technologies comprising of multi-stage continuous polymerisation, continuous extraction and drying of chips, spin draw technology or high speed spinning process are not yet available indigenously.The recent trend in India to look to the ââ¬Ëeast' for technology may be due to the availability of technology comparable to those available from the west at a lower know how fees and lower plant costs. 2. 2 Technological Status of Indian Industry (Unit wise): The comparison of installed capacities, actual production and capacity utilisation and financial analysis in terms of net sales, net fixed assets, net profit and net worth over the period of last five years and present specific raw materials and utilities consumptions, wastage generation and recovery etc. for the following selected units is given in para 2. . J. K. Synthetics Ltd. National Rayon Corpn. Ltd. Shri Ram Fibres Ltd. Nirlon Synthetics Fibres & Chemicals Ltd. Barod a Rayon Corporation Ltd. Details of the historical background, sources of technology, research and development efforts, results achieved, etc. for each of the above units are summarised hereunder. a) J. K. Synthetics Ltd: J. K. Synthetics Limited, pioneer in the manufacture of NTC, have absorbed to a great extent the conventional technology over the last 2 decades. The company has its own research insituteââ¬âThe Sir Padampat Research Centre (SPRC) and has recently floated a companyââ¬âJaykay Tech. hich can supply the conventional technology. As far as horizontal transfer is concerned, conventional technology developed and absorbed by J. K. has little commercial relevance. J. K. ââ¬Ës licenced and installed capacities are 6000 to 5000 TPA respectively. The company has recently entered into technical collaboration with M/s Tong Yang of south Korea for their latest Spin-Draw technology. The new unitwithacapacityofl2. 5TPDiscomingup. b) The National Rayon Corporation Ltd. (N ational Rayon): National Rayon commenced production of rayon tyre cord in 1961 and nylon tyre cord in 1976.The company has a technical collaboration for the latter with Unitika, who have supplied the technology and plant. The company had installed indigenously developed equipment for conversion of polymer waste to granules of spinnable grade. They have successfully indigenised manufacturing of all additives through in-house research as well as developing other suppliers. National Rayon's licensed and installed capacities are 5,000 and 5,250 TPA respectively. The company's performance during 1983 and 1984 had been adverse due to closure of plant because of labour problems.The production during 1985 to 1988 is more than the licensed capacity. As a part of modernisation and expansion programme they have installed spin-draw machines. The spin-draw yarn produced and made into fabric has alreadybeenapprovedbythecustomers. National Rayon have a fullfledged R centre approved by the Governme nt of India and is engaged in import substitution, technology absorption, machinery development and trouble shooting. National Rayon have developed process technology for polypropylene industrial yarn of high tenacity and has been regularly supplying polypropylene yarn for market development.It has also developed rayon industrial yarn, an industrial fabric for non tyre applications. National Rayon have recently installed, for the first time in India, air jet looms for making tyre fabrics of high quality. c) Shri Ram Fibres Limited (SRF): SRF' s plant for manufacture of nylon tyre cord and yarn was commissioned in 1974 in technical collaboration with Unitika. Company's present capacity is 6,335 TPA. SRF has a full-fledged Research and Development Laboratory and is constantly updating process methods and technology for product development.SRF have an independent research institute too. A very recent process developed and patented is that for polymerisation of nylon-6,6. d) Nirlon Synt hetic Fibres & Chemicals Ltd. (Nirlon) Nirlon commenced production of nylon filament yarn and tyre cord in 1962. The company had recently gone into technical collaboration with Zimmer for an expansion of their nylon tyre cord plant. Their present capacity is 5,000 TPA. Zimmer's design is based on multi polycondensation process and single stage spin draw process. Nirlon has a well established research and development base.The company had absorbed the conventional technology for manufacture of nylon tyre cord and is concentrating in developing and acquiring more modern manufacturing process. e) The Baroda Rayon Corporation Ltd. (Baroda Rayon) Baroda Rayon commenced production of rayon in 1962. Subsequently, the company commenced production of nylon tyre cord in 1981 in technical 8 collaboration with Unitika. Their present installed capacity is 2,000 TPA. Expansion of their plant to 4,000 TPA is under implementation and is expected to be commissionedby end 1987. f) The following new un its likely to come up in the near future.The present status / each of these projects is given in detail in para 2. 1. GarwareNylons Limited: Presently the company manufactures nylon and polyester filament yarn and is expanding its activities to manufacture nylon tyre cord, nylon tyre and industrial fabric in collaboration with Allied Corporation, U. S. A. , the largest producer of tyre cord in the world. Century Enka Limited: The company's major activity is manufacture of nylon and other man made fibres and plastics. Century Enka has a collaboration with their principals Enka International of Holland for the technology for manufacture of nylon 6 tyre cord.The production has commenced recently. Ballarpur Industries Ltd. andE. I. Du Pont Nemours & Co. of U. S. A. : They have jointly proposed to promote a Rs. 130 crores joint venture company to produce nylon-6,6 tyre cord for the first time in the country in collaboration with economic development corporation of Goa. An annual producti on of 16,700 tonnes of nylon-6,6 tyre yarn is envisaged. Kanoria Alkalies & Plastics Ltd: They have entered into collaboration for technical know-how, plant and machinery for manufacture of nylon tyre cord with Unitika which has been approved by Government of India. 0. 2. Status of Raw Material Industry: At present only Gujarat State Fertiliser Corpn. Ltd. , Baroda manufacture caprolactam with the capacity of 20,000 TPA in India. Three LOI have been issued by the government with a total capacity of 2,20,000 TPA. The demand projections for caprolactam made by the Committee for Perspective Planning of Petrochemical Industry by 2000 AD are 1,16,000,1,96,000 and 3,02,000 TPA for year 1989-90,1994-95 and 1999-2000 respectively. Hence, till the units who have LOI go into production, imports of caprolactam is unavoidable. The quality of indigenous caprolactam in terms of its permanganate no. nd also in terms of consistancy between various batches of manufacture is not comparable to that of imported caprolactam. 0. 2. 4 Status of Tyre Industry International: There are three types of tyre construction viz. , bias, bias-belted and radial. Radial and bias belted construction are more efficient than simple bias construction. In the world tyre market, radial tyres dominate. They were first inroduced in passenger cars then in commercial vehicles, buses and truck respectively. In U. S. A. market, no rapid change over from bias to radial tyres took place because of the tremendous capital investment required.Instead, belted bias tyres which could be manufactured on existing equipments were developed. The current trends in tyre design and manufacturing include: Use of fewer fabric plies in tyres by utilising larger and stronger cords. Use of special treatments in yarn manufacturing of the cord processing to reduce the creep of cords in tyre. Use of newer fibres such as polyester and modified nylons etc. 0. 2. 5 Status of Tyre Industry -Indian: The installed capacity of Indian t yre industry is 12 million nos. per annum, the estimated demands of tyres by 1989-90 and 1994-95 are around 21 and 31 million nos. espectively, as per estimates of Automobile Tyre Manufacturers' Assocation (ATM A). Preference so far has been towards bias angle, because of the practice of overloading; practically no care of tyres by owners / drivers and poor road conditions. However, some radial passenger car tyres have also been introduced in the market. Due to the higher melting point of nylon-6,6 and polyester as compared to that of nylon-6, the tyre curing temperature can be increased to 250à ° C from 210à ° C (for nylon-6). This would make curing of tyres faster and hence reduce curing cycle.This would result in higher output and also higher productivity. In practice, howevr, fast curing is not realisable in case of heavy duty tyres as the thicklayer of tread rubber will get distortedby fast curing. To take advantage of this higher productivity, the tyre manufacturers will hav e to install higher capacity curing furnaces, which will require substantial investment. Hence, before tyre manufacturers decide to install such furnaces, they would like to confirm regular availability of nylon-6,6 tyre cords at reasonable prices preferably from more than one supplier. 10The switch over from nylon-6 to nylon-6,6 would also result in more down time in tyre manufacturing. Similarly switch over from nylon to polyester requires change in dip condition, double dip processing and more downtime. Hence, whatever nylon they use, they will use it for 100 % of their requirements. 0. 2. 6 Tyre Cord and its Suitability for Various Types of Tyres: Different types of tyres require tyre cords with different properties, indicated in para 2. 12. Radial tyre or belted tyre designs take adavantage of these different requirements by placing different types of cords in the belt and in the carcass.As per the test carried out by one of the Indian radial tyre manufacturers, nylon-rayon was found to be the best combination for Indian conditions. 0. 2. 7 Status of Tyre Cord Industry -International: Major varieties of cords suitable for tyres are cotton, rayon, nylon, polyester, steel, glass fibres and aromatic polyamides. Although flat spotting shown by nylon was originally objected to strongly, nylon has continued to be the preferred tyre cord material because of its price and its superior thermal and fatigue resistance.Nylon-6 is used in Europe and other developing countries while nylon-6,6 is more prominent in U. S. A. mainly due to the manufacturing facilities established and availability of basic raw material. During the last ten to twelve years development have been largely of evolutionary nature aiming to overcome limitations of existing tyre fibres and to make them acceptable for wideruse. 0. 2. 8 Status of Tyre Cord Industry in India: Tenacity of NTC available to Indian tyre manufacturers locally varies from 8. 4 to 9. 4 with average value of 9. 2 gpd.The pres ent demand of NTC in India is around 25,000 TPA which is likely to grow to 40,000,50,000 and 61,000 TPA by 1990,1995 and 2000 AD respectively. At least for next 10-15 years, even in case of radial tyres, nylon would continue to remain as one of the components either in carcass or as belt material. With the existing manufacturing facilities, the type of vehicles in use and existing road conditions, nylon-6 will remain the material of choice except for a small quantity of radial tyres for passenger vehicles where polyester may prove to be superior.At present very little nylon-6,6 is used in India, both for textiles and industrial applications. Besides nylon-6,6 is not produced indigenously. Nylon-6,6 is costlier than nylon-6 worldwide and is likely to be more so in India. Nylon-6,6 is unlikely to be used by tyre companies for their bus and truck tyres 11 (weightage 80%) in near future, mainly due to generation of high shoulder temperature. In view of the above, establishment of fresh production capacities for nylon-6,6 industrial yarn in India may not have much scope considring interest of industry as well as the end-users. . 2. 9 State ofthe Art Scene (International) Twenty five leading manufacturers of NTC in the world are listed in para 2. 15. 1. SalientFeatures of Contemporary Technologies: The technology for manufacture of NTC is standardised as far as polymerisation process is concerned. Product characteristics of different technologies may vary marginally depending upon the type of additives and stabilisers used, design of equipment and control method of production parameters. However, design of spinning plants differs from supplier to supplier.Salient features of contemporary technologies of the following technology suppliers who have supplied/offered technologies to India are discussed in detail in para 2. 15. 2. Zimmer A . G. , West Germany. Lurgi GMBH, West Germany. Unitika Ltd. , Japan. E. I. DuPontDeNemours&Co. ,U. S. A. SniaBPD, Italy. Some importa nt features of these technology suppliers are described in subsequent paragraphs: Zimmer A. G. : Zimmer offers production of nylon-6 in continuous polymerisation operation. The specific Zimmer design allows lower water/chip ratio resulting in a high extract content in washing water, thus saving energy to caprolactam recovery plant.The company offers economic standard design for production capacities of 10 to 50 TPD for high viscosity polymer (tyre cord grade). For caprolactam recovery, Zimmer prefers batch operation for higher flexibility regarding quality and capacity. The plant is specifically designed for low caprolactam concentration in waste water, so that it can be either reused in polymerisation plant, or discharged as innocuous waste. 12 For spinning and drawing, Zimmer offers both, the two step separate process and the one step spin draw process. The former process favours production of: i) lower deniers economically i) low shrinkage yarns iii) large variety of yarn types. The one step spin draw process favours continuous production of heavier denier yarns in large capacities. It results in improvedyarn uniformity. .Lurgi GmbH: Lurgi offers both continuous polycondensation and batch polycondensation route for nylon-6 for use in tyre cord and other technical/ industrial yarn. Lurgi also offers caprolactam recovery unit deploymerisation and condensation plant and equipment for evaporation of the extracted water, treatment of concentrated caprolactam water and distillation.The company offers technology for conventional speed spinning as well as high speed spin draw process. Untika Ltd. , Japan: Unitika offers continuous polymerisation process having a pre-polymeriser coupled with continuous extraction, washing and drying of chips. It also offers caprolactam recovery process. In its polymerisation process, Unitika claims 50% saving in polymerisation time. Viscosity of melt can be adjusted as per requirement during pre-polymerisation. The spinning process offered is both conventional spinning and drawing as well as spin draw process. E. I. Du Pont de Nemours & Co. U. S. A. : Du Pont's industrial yarn process is based on nylon-6,6 salt i. e. hexamethylene diammonium adipate. The company has practised the continuous polymerisation technology and has developed conditions which maximise conversion, maintain precise viscosity control and ensure extended service life. Nylon-6,6 is produced continuously in a series of five vessels ââ¬â evaporator, reactor, flasher, separator and finisher. Streamlined design of polymer vessels and distribution system minimises gel formation, recapture of heat and diamine and hence reduces cost of operating system. 3 Preferred Du Pont technology is based on coupling the spinning machine directly to the continuous polymeriser. It also utilises coupled spindraw. The advantages are elimination of chip making, handling, drying and remelting as also provision of maximum polymer uniformity. Du Pont offers exten sively developd quality control and laboratory testing procedures and a single, specially formulated fibre finish for all products. SNIABPD: SNIA is an Italian company giving process knowhow, plants and equipments for manufacture of nylon filament yarn and tyre cord.The company has the spin draw technology. 0. 2. 10 Latest Developments in Manufacturig Process/Design of Equipment: Product Development: Recent developments have been in the areas of improved dimensional stability of the cord, higher tenacity of tyre cords and improved heat stabiliser formulations to reduce the mechanical loss due to heat generation in tyres. Improvements in Polymerisation Process: Recent developments in this area include attainment of higher molecular weight by vacuum finishing, solid phase poymerisation to get final polymer free of extractables etc. addition of chain ââ¬â coupling agents. Other significantadvances includes: For removal of unconverted monomer For lower level of water extractables in nylon polymer For improved flow and temperature distribution For transferring heat to the centre of the reactor and also to equalise flow rates Improvements in Spinning Process: The developments are directed to achieve higher spinning output upto 97% and to spin NTC of high molecular weight and melt viscosity to have high tenacity tyre cord upto 10 gpd. 0. 2. 1 Critical Evaluation of Contemporary Technology: During initial stage the technology of the synthetic fibre remained with only a 14 Falling film / spray reactors, reactorsworkingundervacuum. Organic polymer coating, internally, ofVK tube reactors. Incorporation of a tubular heat exchangerinthereactor. Provision of perforated plates and vertical aluminium partitions. few giants in the category of front line producers. Because of their conservative attitudes, no rapid technology changes were forth coming.However, the role played by the independent engineering companies which took the risks has been a great boon in the developme nt of technology. Technology suppliers can be broadly classified as front line suppliers having production back up like Unitika, Du Pont etc. and engineering companies like Zimmer, Lurgi, etc. Technology from front line producers is superior technology, requiring less time and wastage generation during production stabilisation at plant commissioning stage. However, know-how fees of these suppliers is higher compared to that of engineering companies.Engineering companies have vast experience in plant erection, basic and detailed engineering. Know-how fees of these companies are comparatively lower. The present trend is to look to the East for technology compatible with that of western countries as it is more economical, although of late, they too are becoming expensive. A project profile based on the typical offer of contemporary technology for a 6,000 TPA NTC project is placed at Annexure I. Instead of putting up many small size plants, it would be advisable to put up a few large si ze plants for economy of scale.The improvement in quality of polymer is a developmental activity which is continuous at international level. Indian companies should also endeavour to improve quality by adopting new engineering and equipment development either through their own R department or through their technical collaborations. New and better type of additives and catalysts development at international level should be incorporated by the Indian companies. Spinning plants having higher spinning efficiency and compactness, are always advisable for a country like India,to reduce the cost of production.One step process of very high spinning speed to make full drawn yarn may not be relevant in India, as at present most of the weaving and cord preparatory processes are of conventional type. So the ideal thing would be to change over to readily available higher throughput equipment. 0. 3 0. 3. 1. TECHNOLOGY ABSORPTION AND GAPS: R Efforts in National Laboratories/Institutions and Their Tie Up With Industry: Institutions like IIT, S ASMIRA, MANTRA etc. , private research institutions like 15 Sir Padampat research Centre, Shri Ram Institute of Industrial Reserach etc. nd in-house R centres of manufacturing industry are engaged in minor research projects for optimisation of production parameters or improvement of product characteristics. Developing countries like India although gradually laying more emphasis on its research and development, have not been able to catch up with their developed or advanced counterparts i. e. there is a considerable time lag between adoption of any particular process in some advanced part of the world and its commissioning in India. The efforts made to bridge this gap in the following areas are as folio ws: Indigensation of capital equipments, spares etc.Indigenisation of raw materials. Modifications and improvements in process, plant and equipments. The major constraint faced by manufacturers of indigenous equipments and spares are: non -availability of design and detailed engineering drawings. patented designs of proprietary equipments by technology suppliers, sources of capital equipments recommended by technology suppliers, limited indigenous demand of such equipments. 0. 3. 2 Indian Standards Specification: As a part of standardisation, the Bureau of Indian Standards has developed IS Specifications for methods of tests for tyre yarns as per the following details.IS:4910 Parti Part II Partlll Part IV Part V PartVI Tyre yarns, cords and tyre cord fabrics made from man made fibres, methods of tests for.

The specifications of polyamide tyre cord warp-sheet for automotive tyres published by the bureau is, IS 11926:1987. The spec ifications are given in Table 4. . 3. 3 Profitability of Indian Industry and its Relationships with Technology: At present the profit margins of NTC manufacturers are fairly satisfactory, even with the present conventional technologies and small capacity plants. Interaction with user industry by NTC manufacturers is also quite good. However, the constraints in respect of technology absorption faced by Indian NTC industry are: low capacities of plant. imported capital equipments, parts and spares, non-availability of trained technological manpower, poor labour ââ¬â management relations. . 3. 4 Export Performance Due to high cost of raw materials and also higher conversion costs due to small capacity plants based on older technologies, the Indian NTC industry has not been able to contribute in the export market. 0. 3. 5 Comparison of Product Specification Between Units: In India, the product range and specifications of all the manuacturing units is almost identical. 0. 3. 6 Modern isation Need: As mentioned earlier, cost of production of Indian NTC industry is higher due to small capacity plants based on older technologies.There is an urgent need to modernise these plants to adopt most advanced technologies and a much higher level of operations. 17 However, for such modernisation substantial funds willlbe required. Financial Institutions are giving soft loans under technology development funds and industries have started taking advantage of this scheme. 0. 3. 7 Technology Gap: Technology gaps in following areas have been identified and discussed in para 3. 9 Product developments Plant capacity Polymerisation process Melt spining process Indigenous manufacture of plant and equipments Indigenous availability of raw materials, additives and spin finishes etc.Internationally, cords with yams having 8 deniers per filament and upto 3,000 deniers of cords and 11 gpd tenacity are available, while in India cords with yarns having only 6 deniers per filament and 9. 2 g pd tenacity are manufactured. The average plant capacity of NTC in India, till 1983, was 2,000 TP A against the defined economic size of plant of 6,000 TP A. Polymerisation: Since the modern continuous polymerisation, extraction, washing and drying systems are suited to large capacity, till recently only conventional batch processes were used.Further, continuous polymerisation lines eliminating chip formation (especially in nylon-6,6) and remelting are not in use at preesent, in India. Melt spinning: More efficient large capacity spinning equipments are being used in the world. These have sophisticated yarn sensing and monitoring systems and hence the quality of yarn is much better with higher throughput. Such latest spinning processes are not available in the country and such technology is now being imported. 18 Reasons for technological gaps are: seller's market situation large number of small capacity plants. otalabsence of exportmarket. good financial performance of Indian Indus try even with the available technologies. general / absence of R&D efforts and know-why exercises, limited developments in the Indian automobile industry, lackof product upgradation at tyre manufacturer's end. To bridge the technological gaps, import of latest spinning equipments and process know-how for spin draw and high speed spinning process, designs and drawings for modernisation of existing polymerisation processes are required. 0. 4. 0 SUGGESTED: STEPS TO BRIDGE TECHNOGICAL GAPThe following suggestions are made to bridge the technological gap: a) Latest technology comprising of continuous polymerisation in two stage V K Tube reactors, continuous extraction and drying of chips, spin draw technology or high speed spinning processes for fully oriented yarn may be imported and horizontally transferred in India. Although some pilot units have been installed by spinners, the industry seems to be waiting for customers' acceptance. b) Develop indigenous manufacture of selected equipm ents, wherever it is economically viable and import only latest plant and equipments on selective basis. ) Develop basic and detailed engineering expertise in Indian engineering companies to necessitate import of only design and drawings for new plants rather than package import. An engineering organisation having expertise in basic and detailed engineering should be encouraged for development and transfer of technology for NTC and related products. d) Widen R&D efforts both at industry and research institutions level with active association and close cooperation between them. e) Provide necessary incentives to indigenous development of manufacture of plant and equipment. 9 f) Permit only large sized plants. g) Provide incentives for intensified research activities at industry level with close monitoring of such incentives. Establish a central tyre research institute with facilities to test developments in new designs of tyres, new tyre cord materials and modifications in tyre cord materials. Develop skills in technical personal, by arranging training abroad or by arranging traimng programmes by institutions like IIT, S ASMIR A, etc. and constant interaction with foreign experts. 20

Learning from Ancient and Modern Themes and Customs Essay
Learning from Ancient and Modern Themes and Customs It has been said that there are under thirty plots in the world, and that all stories, in all languages, all over the world and throughout history, are simply variations on these. Parallels can be drawn between all literature; however, classical mythology has had particularly far-reaching effects on our present civilization. Modern society holds a fascination with Greek and Roman society, and classical literature and mythology are certainly no exceptions.

A scientific theory has been put forward that the universe has been expanding more and more slowly since the Big Bang, and will eventually begin to contract until it disappears altogether. It is natural for humankind to wonder if the Earth and our species are, in fact, finite.

Evidently, the most well known flood in Western civilization is the Bible story involving Noah and the Ark. However, legends of a flood can be found in the folklore of the Middle East, China, India, Australia, Europe, and North and South America. The legend upon which the tale of Noah is based actually originated in Mesopotamia. The Mesopotamian flood myth appeared in the Ep ic of Gilgamesh (one of the first literary classics), the narrative regarding the adventures of a hero-king of Sumer.

The Middle Kingdom Period of Ancient Egypt
Running from the end of the first intermediate period to the start of the second, the Middle Kingdom lasted from about 2055-1650 B.C. It was composed of part of the 11th Dynasty, the 12th Dynasty, and current scholars add the first half of the 13th Dynasty. Predynastic EgyptPharaohs of the Predynastic Period, Old Kingdom and Middle Kingdom Middle Kingdom Capital When 1st Intermediate Period Theban king Nebhepetra Mentuhotep II (2055-2004) reunited Egypt, the capital was at Thebes. Twelfth Dynasty king Amenemhat moved the capital to a new town, Amenemhat-itj -tawy (Itjtawy), in the Faiyum region, possibly near the necropolis at Lisht. The capital remained at Itjtawy for the rest of the Middle Kingdom. Middle Kingdom Burials During the Middle Kingdom, there were three types of burials: surface graves, with or without coffinshaft graves, usually with coffintombs with coffin and sarcophagus. Mentuhotep IIs mortuary monument was at Deir-el-Bahri in western Thebes. It was not the saff-tomb type of previous Theban rulers nor the reversion to Old Kingdom types of 12th Dynasty rulers. It had terraces and verandahs with groves of trees. It may have had a square mastaba tomb. His wives tombs were in the complex. Amenemhat II built a pyramid on a platform -- the White Pyramid at Dahshur. Senusret IIIs was a 60-m high mud-brick pyramid at Dashur. Acts of the Middle Kingdom Pharaohs Mentuhotep II made military campaigns in Nubia, which Egypt had lost by the 1st Intermediate Period. So did Senusret I under whom Buhen became Egypts southern border. Mentuhotep III was the first Middle Kingdom ruler to send an expedition to Punt for incense. He also built fortifications at Egypts northeastern border. Senusret instituted the practice of building of monuments at every cult site and paid attention to the cult of Osiris. Khakheperra Senusret II (1877-1870) developed the Faiyum irrigation scheme with dykes and canals. Senusret III (c.1870-1831) campaigned in Nubia and built fortresses. He (and Mentuhotep II) campaigned in Palestine. He may have gotten rid of the nomarchs who had helped cause the breakdown leading to the 1st Intermediate Period. Amenemhat III (c.1831-1786) engaged in mining operations that made heavy use of Asiatics and may have led to the settling of Hyksos in the Nile Delta. At Fayum a dam was built to channel Nile overflow into a natural lake to be used as needed for irrigation. Feudal Hierarchy of the Middle Kingdom There were still nomarchs in the Middle Kingdom, but they were no longer independent and lost power over the period. Under the pharaoh was the vizier, his chief minister, although there may have been 2 at times. There were also chancellor, overseer, and governors of Upper Egypt and Lower Egypt. Towns had mayors. The bureaucracy was supported by taxes assessed in kind on yields (e.g., farm produce). Middle and lower class people were forced into labor which they could avoid only by paying someone else to do it. The pharaoh also gained wealth from mining and trade, which appears to have extended to the Aegean. Osiris, Death, and Religion In the Middle Kingdom, Osiris became the god of the necropolises. Pharaohs had participated in mystery rites for Osiris, but now [rivate individuals also took part in these rites. During this period, all people were thought to have the spiritual force or ba. Like the rites of Osiris, this had formerly been the province of kings. Shabtis were introduced. Mummies were given cartonnage masks. Coffin texts adorned the coffins of ordinary people. Female Pharaoh There was a female pharaoh in the 12th Dynasty, Sobekneferu/Neferusobek, daughter of Amenemhat III, and possibly half-sister of Amenemhet IV. Sobekneferu (or possibly Nitocris of the 6th Dynasty) was the first ruling queen of Egypt. Her rule of Upper and Lower Egypt, lasting 3 years, 10 months and 24 days, according to the Turin Canon, was the last one in the 12th Dynasty.

Issues in the Italian Culture-Free-Samples-Myassignmenthelp.Com
Question: Discuss about the various Issues in the Italian Culture. Answer: Introduction The following paper discusses about the various issues in the Italian culture. Some of the cultural facts are also related with the Italian lives as well. I would be highlighting on the different issues that have been relevant in the rise of the Italian culture and the things that made the headlines. The different issues in the Italian life and culture include the facts like mafia, the Renaissance artists, the Roman Empire and the improvements that took place in that time, the philosophers and the experiences in the Naples Italy museums. I would like to display the contributions that they had served to enrich the Italian life and culture. This is extremely essential to know about the contributions of those people in the rise of the Italian culture before the whole world. Italian mafia The mafia groups in Italy had been the organized crime groups that had come to its contemporary situation over the centuries and it was raised from the island of Sicily that was ruled by the foreign invaders until of the middle of the nineteenth century (Paoli 2014). The people of Sicily very often went on to protect themselves in groups and they had always carried out their own justice in terms of people or place. The term mafloso could be applied to the Sicilians because it meant the mafia members. At the beginning this word mafia had no connotations about criminal things. The Sicilian Island belonged to Italy at that time and the thing is that the Sicilian mafia rose to power and they formed mafie which were the armies for the people who gained the power to extort the money from the landowners (Decker and Pyrooz 2013). Italy became a unified country and Sicily became a part of it. The government of Italy was just trying to gain the control by establishing themselves and they wanted the help from the Sicilian mafia to chase the dangerous and independent criminal groups. The government assured them that they would look at them in other ways (Decker and Pyrooz 2013). The expectation of the Italian government had failed and the mafia clans continued their quest of criminal activities further. The mafia became a controlling power in the political corruption and the Catholic Church had joined with the mafia clans in Italy. They had followed the code of conduct omerta in the Italian ground very strictly. The Roman times The Roman times or the Roman Empire had a very important significance in the Italian culture. Roman Empire had been one of the major centers of Renaissance. Many cultural improvements took place here through many centuries. All types of things that influence the culture like science and technology, sculpture, theatre, visual art and music had been very important in this context (Garnsey and Saller 2014). The writing of the ancient music was written in Italy and many famous musicians came to prominence in the Roman era (Stephens 2014). I would like to highlight that in this period many beautiful pieces of literature were also written as well. Italy had provided classical musical tradition and set an example before many countries. I must mention the name of the La Scala opera house in Milan that is considered to be one of the best known auditoriums in the world. Giovanni Palestrina had composed several masterpieces of music in the Renaissance period. The evolution of ballets also emerg ed in this time (Bury 2012). Some other important artworks that could be found to showcase the brilliance of Italian culture are Crucifix, The Baptistery Doors, The Four Crowned Martyrs, Deposition of Christ, The Life of the Virgin, The History of True Cross and numerous others. The rise of art especially sculptures, occurred in the Roman Empire with the Augustus of Primaporta. In this period, the pure realism of the Republican period was joined with the Greek idealism. The great sculpture designs of Michelangelo had become very prominent. This was due to the fact that the Roman emperors always paid patronage to the artists of the time who enriched the contemporary culture. So I suppose that they were one of the main people to play the role of influencing the people. Renaissance artists and philosophers In this part of the paper, I would be highlighting about the different aspects of the Roman culture and the Italian life and culture as a whole (Burke 2013). The focus will be on the role of the Roman arists and philosophers who had evolved in the period of Renaissance. In fact, it can be said that Renaissance was the time when most of the prolific artists had gained the prolific rise. Several artists had been on the threshold of proving themselves in front of the world to be the very best. Some famous artists that came to the limelight in the Renaissance period are Michelangelo, Giotto, Raphael, Titian, Donatello, Domenico Ghirlandaio and several others. The famous philosophers who reigned supreme in that period of Renaissance were Petrarch, Niccolo Machiavelli, Giovanni Pico della Mirandola, Marsilio Ficcino, Bernardino Telesio, Lucilio Vanini and several others (Burke 2013). I strongly believe that they had contributed a major part in the success and upliftment of the Italian life and culture (Wilson 2016). Some of the major artworks in this Renaissance period are David, The Last Supper, Annunciation, The Last Judgment, The Creation of Adam, The Sistine Madonna and many others. The important philosophical traits that were discussed in this time were Humanism, Neo-Platonism, Machiavellian and others (Audi 2015). Naples Italy museums The Naples Italy museum is considered to be one of the most important parts of the culture of Italy. It is related with the Italian people as well. The museum depicts the history of several things that have influenced the lives and culture of the people (Amato et al. 2013). The things that are embedded in the museum are the quality works of the Greek, Roman and Renaissance times. The things include the typical archaeological things as well. These things have enriched the culture of Italy to a certain extent. Some of the important figures that are present in the museum are Farnese Hercules, Farnese Atlas, Farnese Bull, Venus Kallipgyos, Harmodius and Aristogeiton and several other things. They have a collection of the busts of many Roman Emperors that shows the rich tradition Italy had. There are some important instances of mosaics present in the museum from the ruins of the Pompeii. These important mosaics include Alexander Mosaic that could date back to 100 BC was found from the House of Faun in Pompeii. Another important instance of fresco painting was the fresco of Heron and Cobra that was found from the House of Epigrammes. These things have been found after a tireless effort of the archaeologists to prove the rich cultural tradition Italy ever possessed. Another important mosaic painting includes the Cave Canem (beware of dog). I suppose these are precious documents of the Italian life and culture and should be preserved for the generations to come (Astarita 2013). Conclusion This paper can be concluded by saying that Italian life and culture has been one of the most beautiful and brilliant pieces of artwork. The Renaissance period has given birth to many stalwart people in various fields of art. The philosophers of this period also catered to the betterment of the culture. In this paper, I have discussed various things about the Italian mafia and its influence on the lives of people. The influence of the Renaissance has been immense in this sense because the famous works of art, painting, sculpture and philosophical pieces have evolved in this period only. So, it is of immense significance to know about these things. References Amato, F., Chianese, A., Mazzeo, A., Moscato, V., Picariello, A. and Piccialli, F., 2013.

Acid Rain Legislation Essay Example For Students
Acid Rain Legislation Essay Acid Rain LegislationAcid rain is a destructive force as a result of nature and man colliding. It is formed through harmful industrial emissions combining with contents ofthe earths atmosphere; a dangerous combination. This prompted governmentsthroughout North America to take action. Many laws and regulations have beenimplemented, yet the question still remains, Should tougher legislation beimplemented to force industries to reduce acid rain emissions?To decide whether tougher legislation should be implemented, one mustfirst understand the details of what exactly acid rain is. Acid rain is aresult of mankinds carelessness. It travels a long one of the most efficientbiogeochemical cycles on earth, the Hydrologic Cycle. This allows acid rain todistribute itself further away from its source causing more than local problems. Sulfur Dioxide (SO2) is released by fossil fuels when they undergo combustion. Power plants and other fossil fuel burning industrial areas release variousforms of nitrous oxides (Nox). These two chemical compounds combine with thewater in the atmosphere to form what is known as acid rain. The main reason that has prompted legislation of industrial emissionsfrom governments is because of the negative effects they can have on theenvironment. Acid rain is harmful to the environment because of its low pH. It can harm the biotic components of earth, and also the abiotic components. Its high acidity degrades soil to the point where it cannot support any type ofplant life. Trees in forests are killed over long-term exposure. When thesetrees are killed, an imbalance in the hydrologic cycle can occur. Withoutliving trees to consume the precipitate, it must be consumed by the earth or anyother plants. These will receive an excess of water, causing other problems inthe hydrologic cycle. This in turn causes a chain reaction of death among ourforests. Some regions are more susceptible to acid rain because they dont haveenough Alkaline soil to neutralize the acid before it is able to destroy therest of the soil or before it can run off into lakes or rivers. Aquaticenvironments can be greatly affected by soil runoff. Acidic soil may runoffinto lakes and rivers due to erosion, causing acid rain to destroy moreenvironment. Acid rain aquatic animals as well as aquatic plant life. Whenacid rain combines with water in major bodies of water, it not only destroyswildlife habita t, it destroys our drinking water. An aquatic ecosystem is verydependent on each and every aspect within itself. Once one species dies off,others that depend on it, will eventually begin to die off also. Thissystematic chain continues until the entire body of water is completely abiotic. The reason acid rain is so effective in destroying ecosystems is because itharms everything in that particular ecosystem. Being distributed through thehydrologic cycle, acid rain is capable of destroying everything in its path. Many laws and agreements have been implemented by governments in NorthAmerica to reduce acid rain emissions. The question governments are asking is:Are these regulations enough?. One of the more famous laws/organizationsimplemented by North American governments was the Clean Air Act which wassigned in 1991. Also in 1991, Canada signed an agreement with the United statesconcerning air quality. Media explains that the agreement has enough frameworkto address all transboundary air pollution issues. It is a very broad/generalagreement that should highly reduce air pollution between these two majorcountries of the world. This agreement contains other specific commitments foremissions reductions relating to acid rain precursors and research as well as acommitment to review the Agreement in its fifth year. This allows forexpansion of the agreement in the near future. Research and studies forced bythis agreement is also an intelligent decision among these countries; educationis the basis of all knowledge. Besides agreements and legislations of sorts,technology is an awesome force in the reduction of acid rain emissions. Theonly down side to this technology is that it is extremely expensive. Scrubbershave been placed in the smokestacks to remove harmful emissions. Lime is usedin lakes to neutralize the low pH levels. Without studies being conducted andresearch being taken out on acid rain, these technologies would not be heretoday. This is why education may be the ultimate technology in the reduction ofacid rain emissions. .u851b714c286bee959971db0d257363aa , .u851b714c286bee959971db0d257363aa .postImageUrl , .u851b714c286bee959971db0d257363aa .centered-text-area { min-height: 80px; position: relative; } .u851b714c286bee959971db0d257363aa , .u851b714c286bee959971db0d257363aa:hover , .u851b714c286bee959971db0d257363aa:visited , .u851b714c286bee959971db0d257363aa:active { border:0!important; } .u851b714c286bee959971db0d257363aa .clearfix:after { content: ""; display: table; clear: both; } .u851b714c286bee959971db0d257363aa { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u851b714c286bee959971db0d257363aa:active , .u851b714c286bee959971db0d257363aa:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u851b714c286bee959971db0d257363aa .centered-text-area { width: 100%; position: relative ; } .u851b714c286bee959971db0d257363aa .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u851b714c286bee959971db0d257363aa .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u851b714c286bee959971db0d257363aa .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u851b714c286bee959971db0d257363aa:hover .ctaButton { background-color: #34495E!important; } .u851b714c286bee959971db0d257363aa .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u851b714c286bee959971db0d257363aa .u851b714c286bee959971db0d257363aa-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u851b714c286bee959971db0d257363aa:after { content: ""; display: block; clear: both; } READ: Agriculture In US EssayShould tougher legislation be implemented to force industry to reduceacid rain emissions? From an environmental point of viewyes, anything thatcan be done, should be done. Whether it be through studies, research, newtechnologies, anything for our environment. From an economical point ofviewno, technology is very expensive and hardly affordable in terms of mostindustries. Technology can reduce the dangers of acid rain, but at what cost?Tougher legislation should be implemented to preserve our environments, topreserve our lifestyle, and life on earth. Social Issues
