Hot and Cold Essay Example for Free
Hot and Cold Essay Since time immemorial, Indians have been bombarded with snacks-to-go by street vendors; fastfood is neither a modern phenomenon, nor a western innovation. But as increasing numbers of international players enter the domestic market, there are bitter lessons to learn about what local consumers will and will not welcome. just-food.coms Debasish Ganguly reports from India on the evolving sector and the challenges facing new entrants into the fastfood market. Fastfood is not an alien concept to Indians; roadside shops have offered snacks-to-go since time immemorial and the country has a long tradition of indigenous fastfood served by a variety of street vendors. Whether the southern Dosas or the Phulkas in the north, the Vada, Samosas or Bhelpuri, this inexpensive cuisine is still going strong, and street selling is a low-cost method of food distribution. However, since the arrival of established fastfood chains such as McDonalds, marketing savvy and dollar power have given fastfood a very western orientation. The weekend stampedes outside any McDonalds restaurant are standing testimony to this fact. But the burger behemoths still have a long way to go. Local fastfood is not easily undermined by these interlopers, since methods of mass production have not been perfected and, in any case, they would have to compete with low cost artisan production. On the other hand, the reality is that established local fastfood chains, like Nirulas, Wimpys or Haldiram, are sensing competition by the growing popularity of McDonalds and other international chains. Though Nirulas does not admit to any drop in sales overtly, industry sources reveal that they have lost 18% of their original market share. So far, the fastfood chains have gained their popularity among the major metropolitan cities of India and some smaller cities, such as Pune or Baroda. Before the arrival of these fastfood chains, Nirulas was the market leaderin Delhi. In fact, Nirulas taught Delhi-dwellers what pizzas and burgers were all about. Nirulas was commanding a monopoly until western chains arrived in India.

John Stuart Mills Essay -- Essays Papers
John Stuart Mills John Stuart Mill was one of the most well regarded and widely renowned philosophers and economists in history. He was considered a philosophical genius by the age of 20, and was mainly taught only by his father. His father believed that he should be educated and be taught many different languages and philosophies to become a well-rounded individual. When he had to end his studies early in life because of a mental breakdown at the age of 20, he soon recovered and was something different than when he first studied. Not long after he recovered he showed how different he was than his father and began writing in the Westminster review. He has widely been known for his views on liberalism that he showed in On Liberty. Mill believed that the individual was essentially sovereign over his own mind and body, a belief known as individual autonomy. The only thing individuals could do justifiably to violate other individuals' autonomies was in pursuit of self-protection, where the other individuals had broken into theirs first. Millsian philosophy was completely against negative liberty, or the absence of restraint, chaos. However, on the other end of the spectrum, Mill also opposed the tyranny the majority could impose on any minority, particularly the individual, by way of legislative control. Mill strongly believed in the practice and respect of law, and that minorities of any sort should be protected and only suppressed if the greatest good for...

Lead Contamination in Agro-Based Products as Current Public Health Threat in Bangladesh
Lead contamination in agro-based products as current public health threat in Bangladesh A. M. M. Maruf Hossain1*, M. Shahidul Islam2, Md. Moklesur Rahman1, Md. Mustafa Mamun1, M. Azizul Islam Kazi2, and Syed Fazle Elahi1 1Department of Soil, Water and Environment, Faculty of Biological Sciences, University of Dhaka; 2Analytical Research Division, BCSIR Laboratories, Dhaka. *Corresponding author Abstract: Agro-based products are primary to all human food sources. Contamination in these is also the easiest way of human health getting affected in large scale. Among the myriad of agro-based products, commercially produced milks and eggs were sampled. Chicken eggs were sampled from Dhaka and its nearby other seven districts covering the central region of Bangladesh. Dhaka, Narsingdi, Kishoreganj, Mymensingh, Tangail, Gazipur, Narayanganj, and Munshigonj were selected for the study. Twelve eggs were randomly sampled from each district’s egg stock market. In Dhaka, Gazipur, and Tangail’s market both brown and white colored eggs were found. Six eggs from each type were sampled from these three districts. In the rest five districts only brown colored eggs could be found. Commercial liquid milks of 13 prominent milk producers have been sampled with replication. Introduction: Poultry plays a vital role in the economy of Bangladesh in recent years. The contribution by livestock is 3% of the total GDP (BBS, 2004) and nearly 10% of the agricultural GDP (Poultry Business Directory, 2007). As food poultry provides meat and egg. An egg is a good source of energy, protein, and fat. A 50 g weighing grade A chicken egg provides estimated values of 297 KJ energy, 6g protein, 5g fat (1. 5g saturated, 2. 0g monounsaturated, and 0. 8g polyunsaturated), and 190mg cholesterol. Chicken eggs are the most commonly eaten eggs, and are highly nutritious (FAO, 2007). They supply a large amount of complete, high-quality proteins (which contains all essential amino acids for humans), and provide significant amounts of several vitamins and minerals, including vitamin A, riboflavin, folic acid, vitamin B6, vitamin B12, choline, iron, calcium, phosphorus and potassium. Again liquid milk is an important source of fat, lactose sugar, and proteins (Casein, Albumin). Egg and milk are essential contexts to our daily diet. Bangladesh has a long historical record of raising poultry under traditional backyard farming. In 1935 improved variety of birds were first introduced in the countries. In the long run it is in the early nineties that a number of private parent stock farms have started their operation to produce commercial Day Old broiler and layer Chicks. Today for commercial egg production layer chicks from these farms are being used. Commercial egg production mostly uses the layer breeds of Hyline Brown, Hyline White, Hisex Brown, Hisex White, ISA Brown, Lohman Brown, Shaver White, and Shaver 579. The prominent milk producers have their own farms in Bangladesh. They produce and market both pasteurized and UTH (ultra high temperature) processed milks. For egg and milk urban people depend completely on commercially produced products while rural people have some practice of backyard farming. As industrial and agricultural practices are not strictly regulated and maintained environment-friendly in Bangladesh, contamination can happen in many ways especially with heavy metals. For this reason a widely distributed egg samples have been collected from Dhaka and its surrounding other seven districts where industrial activities and hence pollution is most prevalent. Similarly a number of liquid milks were sampled with replication to reflect a representative picture. Materials and Methods: Sampling area for egg: The egg sampling area constituted eight districts including capital Dhaka and covered the central region of Bangladesh. Dhaka, Narsingdi, Kishoreganj, Mymensingh, Tangail, Gazipur, Narayanganj, and Munshigonj were selected for the study. Twelve eggs were randomly sampled from each district’s egg stock market. In Dhaka, Gazipur, and Tangail’s market both brown and white colored eggs were found. Six eggs from each type were sampled from these three districts. In the rest five districts only brown colored eggs could be found. The sampling area is shown in gray color in Figure 1. Figure 1: Map of Bangladesh representing the darkened study area Milk sampling: Commercial liquid milks of 13 prominent milk producers have been sampled with three replications in each. These covered liquid white, mango, chocolate, and banana milks. Aarong – white, Aarong – chocolate, Aarong – mango, Milkvita – white, Milkvita – chocolate, RD – white, RD – mango, RD – banana, Amo – white, Amo – chocolate, Amo – mango, Pran – white, and Starship – chocolate liquid milks were selected for the study. Sample pretreatment: ? The egg samples were boiled in deionized water and after complete boiling albumen and yolk were separately oven-dried at 80oC to remove all moisture. The samples were oven-dried unless the difference between two readings of weight was found negligible. Each of oven-died albumen and yolk were treated and analyzed separately. ? A portion of the liquid milk samples were used for density measurement. Milk samples were treated and analyzed as it is. Sample preparation method: The samples were prepared by using HNO3 – HClO4 digestion (Kebbekus & Mitra, 1998). Since the samples were of organic origin with a very high organic content, HNO3 – HClO4 digestion was preferred over the more common HNO3 extraction for the determination of heavy metals. This strongly oxidizing digestion decomposes organics quickly and efficiently. Sample analysis: Analysis of all prepared samples was performed through atomic absorption spectrophotometry (AAS). BDH standard solution was used for preparation of lead (Pb) standard curve. During the sample preparation for arsenic determination, hydrochloric acid (at least 11. 6 ml concentrated HCl for 100 ml total sample) and KI (at least 1 %) were added. For the other heavy metals no special treatments were done. Hydride vapor generation technique was used in the determination of arsenic and mercury. Chromium, cadmium, lead, and arsenic determination were done in air-acetylene flame whereas mercury determination was done in cold vapor. The lead (Pb) contamination in eggs is calculated by using the average parameter values of total 96 eggs sampled, where albumen and yolk have been studied separately in each egg (Table – 1).

Life and Thoughts of Mahatma Gandhi - 3441 Words
Life and thoughts of mahatma Gandhi Mohandas Karamchand Gandhi was born in 1869 in the coastal town of Porbandar, one of scores of tiny princely states and now part of theIndian state of Gujarat. Although the Gandhis, meaning grocers, were merchants by caste, they had risen to important political positions. Mohandas’s father was the chief administrator and member of the court of Porbandar, and his grandfather that of the adjacent tiny state of Junagadh. Gandhi grew up in an eclectic religious environment. His parents were followers of the largely devotional Hindu cult of Vishnu (or Vaishnavites). His mother belonged to the Pranami sect, which combined Hindu and Muslim religious beliefs, gave equal honour to the sacred books of the†¦show more content†¦His similar campaigns against immigration restrictions and discriminatory licensing laws were much less successful. He increasingly began to complain that constitutional pressures, petitions, and rational persuasion were making no impact on ‘prejudiced’ minds, and wondered what else he should do. He found the answer a few years later. When Transvaal passed a law in 1907 requiring the registration and fingerprinting of all Indians and giving the police the power to enter their houses to ensure that the inhabitants were registered, Gandhi hit upon his well-known method of satya ¯graha. It was a form of non-violent resistance and involved peaceful picketing of registration centres, burning registration cards, courting arrest, and gracefully accepting such punishment as was meted out. Gandhi’s protest resulted in some concessions which, however, fell short of his original demands. It was followed by another satya ¯graha, this time involving Indian women and miners, against such measures as the imposition of poll tax, the refusal to recognize Indian marriages, immigration regulations, and the system of indentured labour. This had greater success and led to the passage of the Indian Relief Act in 1914. During his 21 years in South Africa, Gandhi’s ways of thought and life underwent important changes. Indeed the two became inseparable for him. Thought came to have no meaning for him unless it was lived out, and life was shallow unless itShow MoreRelatedResearch Paper On Mahatma Gandhi792 Words  | 4 Pages Mahatma Gandhi Intro: Mahatma Gandhi was the primary leader of India’s Independence movement, He was the person who thought about India, and gave all the rights that India deserved, when the great britain took over India.
