The term “entrepreneur” was coined in America in the late 70’s. A few executives of major corporations in the United States left their jobs to start their own small businesses because the top executives in these companies were not accepting new ideas. Managers who have become entrepreneurs find amazing success in their new businesses. Some of them were dangerous to companies they left a few years ago. This type of businessman came to be known as entrepreneurs. Such a brain drain is a global phenomenon and is not limited to the United States. Industrialists around the world began designing routes and suspending the flight of their most prominent officers. In 1976 Norman Macras wrote to the London Economist that large successful companies should become ‘business partners’’.

Introduction
Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse.
UNEP defines Environmental Impact Assessment (EIA) as a tool used to identify the environmental, social and economic impacts of a project prior to decision-making. It aims to predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment and present the predictions and
options to decision-makers.
Environment Impact Assessment in India is statutorily backed by the Environment Protection Act, 1986 which contains various provisions on EIA methodology and process.
Evolution & History of EIA
EIA is termed as one of the best policy innovations in the 1900s. The main aim of EIA is to conserve the environment and bring out the best combination of economic and environmental costs and benefits. Read the below-mentioned points to understand the Environmental Impact Assessment evolution and history:
• The birth of EIA is dated back to the 1970s.

Concept of Environmental Impact Assessment Introduction, what it is, who does it, how it is done?

Environmental Impact assessment (EIA) is the estimation of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action.

Introduction to EIA

An EIA may be defined as: a formal process to predict the environmental consequences of human development activities and to plan appropriate techniques to eliminate or reduce adverse effects and to augment positive effects. to enhance positive effects.

Introduction

In India the present population of over 1000 million, accounting for about 18 percent of the world’s population, is estimated to become 1.4 billion by 2025 and 1.7 billion by 2050 AD, needing annually about 380 Mt and 480 Mt food grains respectively (Yadhav 2008). This scenario along with the increasing industrialisation and urbanisation will place tremendous pressure on the shrinking natural resources. However, we still have the capacity to produce enough food to meet the basic requirements of the burgeoning population, but the moot question is whether, we can do so while maintaining our natural resources and preserving the bio diversity at the same time. Land are the basic natural resources which are essential for agriculture.

Introduction
Broadly we can say environment means nature. Nature is the mother of the ecology. If we really care for integrity and overall health of nature, then the environment should be preserved and protected from all kinds of threat. The industrial revolution started in the late 18th and 19th centuries as a significant economic development. Industrialization was accelerated by the introduction of power-driven machinery.
This revolution affected the environment a lot. The main cause of this abundant increase in population which obviously increase living standards. To fulfill this high living standard and maintain living at per, we are prompted to deplete natural resources. The random and careless use of chemicals and fuel in industrial sector cause increased incident of air and water pollution. Business venture contributes a major part of the economic development and prosperity of the country as well as provides employment generation and wealth generation but on the other hand cause environmental deterioration.
So we should encourage business venture, entrepreneurial development and industrialization but without harming nature. In order to proceed business venture through smooth way and in a sustainable manner, some legislation or guidelines should make to protect our environment while we are there to maintain entrepreneurial flow.

1. The Aflatoxin Molecule

Aflatoxins are chemically difuro-coumarin derivatives. Presently, 18 different types of aflatoxins have been identified with aflatoxin B₁, B₂, G₁, G₂, M₁ and M₂ being the most common. Of these Aflatoxin B₁ (AFB₁) and G₁ occur most frequently, with AFB₁ being the most potent. Physicochemical and biochemical characteristics of the AFB₁ molecule reveal two important sites for toxicological activity (Heathcote and Hibbert, 1978). The first site is the double bond in position 8,9 of the furofuran ring (Figure 1). The interactions of aflatoxin, DNA and proteins, which occur at this site alter the normal biochemical functions of these macromolecules and leads to deleterious effects at the cellular level.Monteiro et al. (1966) studied the in vitro interaction of groundnut proteins namely arachin and conarachins with AFB₁ molecule. The second reactive group is the lactone ring in the coumarin moiety (Lee et al., 1981). The lactone ring is easily hydrolyzed and is therefore vulnerable to degradation.

Carbohydrates (glucose) are the primary energy source for a body; when digested, glucose is the end product in human beings and simple stomach animals, but it yields volatile fatty acids in ruminants. Precise regulation of levels of blood sugars/glucose in the body is the net result of various processes like digestion, absorption, and metabolism operating under the interaction of various a) enzymes and b) hormones secreted by the different organs of the body. An abnormal secretion of any of the enzymes or hormones associated with the metabolism of carbohydrates disrupts the precise regulation of blood sugar, leading to various disorders.
14.1 Enzyme Deficiency and Disorders in Carbohydrate Metabolism
Usually, various enzymes are involved in the breakdown of carbohydrates, and if their secretion is insufficient, missing, or does not work correctly, it leads to different disorders.
I. Glycogen storage diseases (GSDs, glycogenosis, and dextrinosis)
Glucose is needed by the cells for the generation of energy and other cellular activities. If glucose happens to be in excess, it is stored as glycogen, mainly in the liver and muscles, for future needs. The stored glycogen can be converted back to glucose when the need arises. Many enzymes are related to this interconversion of glucose and glycogen. Deficiencies of one or more enzymes may lead to abnormal glycogen metabolism, leading to glycogen accumulation of normal or abnormal chemical structure in tissue, collectively called glycogen storage diseases (GSDs). Roman numerals identify different types of glycogen storage conditions. They are also classified under various categories like inherited metabolic diseases, autosomal recessive type, and X-linked type (VIII/IX type).

Introduction

Billions of chemical reactions are happening inside human body and that too with lightning speed. However, the same reactions if carried out in laboratory, they take a very long time. The reasons behind it are the biocatalysts, also known as enzymes, which are synthesized by living cells. Chemically, they are proteins(except ribonucleic acids: RNA), colloidal in nature, thermo-labile in character and very specific in their action. For example, hydrolysis of proteins by a strong acid at 100°C takes a couple of days; but same proteins can be digested within couple of hours inside human body at 37°C. Similarly, carbonic anhydrase is used as a catalyst by living cells to transfer carbon-di-oxide from cells to blood. This process is 107 times quicker than the same process if occurs without the help of enzymes. Therefore, enzymes can be defined as the biomolecules or biocatalysts which can speed up the rate of the chemical reactions. The substance upon which an enzyme acts is called as substrate and the one which is produced as the result of enzyme-substrate reaction is known as product.

Enzymes are remarkable biological macromolecules that catalyze chemical reactions with extraordinary efficiency, playing an essential role in sustaining life. These large protein molecules and certain catalytic RNA molecules known as ribozymes accelerate reactions by lowering activation energy, enabling them to occur at rates necessary for biological processes. Their specificity is just as impressive as their speed as enzymes are often highly regioselective and, in many cases, absolutely stereospecific, traits that synthetic chemists strive to replicate. They are vital in metabolism, DNA replication, signal transduction, and cellular respiration, operating under mild physiological conditions. Factors such as temperature, pH, substrate concentration, and the presence of inhibitors or activators influence their activity. Given their significance, enzymes have garnered attention in fields like drug design, disease treatment, and industrial applications. The modern study of enzymes continues to provide groundbreaking insights into chemistry and biology, advancing both scientific understanding and human welfare. Brief History of Enzymes The existence of enzymes was first inferred when specific biochemical reactions were observed to occur only after the addition of cell extracts, even though the enzymes themselves could not be directly identified like typical molecules. In the early days, enzymes within these extracts were highly impure and present in low concentrations, as advanced protein

1. INTRODUCTION

Enzymes are proteins with highly specialized catalytic functions responsible for many essential biochemical reactions in microorganisms, plants, animals and human beings. Enzymes play an important role in many aspects of life since the dawn of civilization that have used enzymes for thousands of years without understanding what they were or how they work. Food processing through the use of biological agents/enzymes is historically a well-established approach. The earliest applications go back to 6000 BC or earlier, with the brewing of beer, bread baking, cheese and wine making. Whereas the first purposeful microbial oxidation dates back 2000 BC, with vinegar production. In the late 19^thcentury, Christian Hansen reported the use of rennet for cheese making and production of bacterial amylases was started at Takamine (latter became part of Genencor). Pectinases have been used for juice clarification in the 1930s and during World War II, invertase was also employed the production of invert sugar syrup in a process that pioneered the use of immobilized enzymes in the sugar industry. Still, the large-scale application of enzymes could only be really established in the 1960s, when the traditional acid hydrolysis of starch was replaced by an approach based in the use of amylases and amyloglucosidases (glucoamylases) and glucose (xylose) isomerase. From then onward, the trend for the design and implementation of processes and production of products by the use of enzymes has steadily increased.

Food and beverages and household care industries represent the largest application areas of enzymes, followed by animal feed, biofuels, textile and other technical industries. Recently, several new developments have taken place in the application of enzymes in fruit and vegetable processing. Fruits and vegetables are consumed as fresh or processed into different type of products. Commercial enzyme preparations are used as processing aids in fruit and vegetable processing to improve the process efficiency and product quality, because enzymes show activity on specific substrates under mild processing conditions. Therefore, there has been a striking growth in the enzyme market for applications in the fruit and vegetable industry.

Enzymes are biocatalysts that change the rate of reaction without being changed themselves. All (Most) enzymes are proteins but all proteins are not enzymes. Ribonuclease is the enzyme which is non- protein in nature.

Chocolate is a product that requires complex procedures to produce. The process involves harvesting coca, refining coca to cocoa beans, and shipping the cocoa beans to the manufacturing factory for cleaning, roasting, grinding , ref ining , conching , moulding and enrobing operations which are accomplished using wide range of machinery. A few have been discussed in this chapter.

1. Bean Roasters

When cocoa beans were first brought to Europe, the method of roasting was quite simple, often consisting of no more than metal trays suspended by chains over a fire, an ancient Middle Eastern technique for roasting coffee. The beans would be stirred by hand with a long stick or paddle until the roast was complete. Needless to day, this was very labor intensive and inefficient. Clearly, something more efficient was needed. The next development in roasting technology was not that far distant from roasters in use today. Metal cylinders or balls that could hold up to several pounds of cocoa beans would be suspended over the embers of a fire. A rod would run through the center and act as an axis upon which the roaster would turn. A hand crank on one end would allow the cylinder or ball to be turned while the beans were roasting. The result was a much more even roast than was before possible. Aspects of this technique remain in many of today’s roasters.

Abstract

The present study aims to assess postural and muscular stress among farm women performing weeding and winnowing operations. Postural stress was assessed through postural deviation in spinal curvature, energy expenditure, physical cost of work, cardiac cost of work, pain in different body parts and muscular stress was assessed by percentage decrease in grip strength. Postural deviations were recorded with the help of flexi curve. Heart rate was calculated in 3 phases: before, during and after the work. Energy expenditure, physical cost of work, cardiac cost of work was also calculated. Grip strength of both hands was calculated by grip dynamometer. The mean value of ergonomic parameters were found more in weeding operation which were as follows : -Postural deviation (250), Average heart rate (5.35), energy expenditure (5.70), physical cost of work (3.05), total cardiac cost of work (35.82). After weeding operation farm women perceived very severe pain in lower back, buttocks, and palms, while after winnowing they experienced very severe pain in shoulder, upper back and upper arms.

Abstract

The present paper examines the effect of fodder cutting and uprooting activity on the cardiovascular system of farm women. The research design comprised of field study conducted on 30 farm women. The activity of cutting and uprooting were studied with the traditional tools as well as with the improved tools. Newly designed and developed slashing knife and uprooter were provided to the respondents for performing the activity of cutting and uprooting. The results revealed significant reduction in average working heart rate (2.08** - cutting and 4.99** - uprooting; Significant at 5% level) and peak heart rate (-3.55**- cutting and 1.70**- uprooting; Significant at 5% level).  It was found that there was significant reduction in muscular stress after use of improved tools over the existing tools.

This chapter applies ergonomic principles to hospitals, clinics, laboratories and other healthcare environments. Healthcare personnel encounter demanding physical tasks, emotional pressures, complex decisions and extended working hours. Common risks include patient handling, repetitive movements, prolonged standing, awkward postures, mental overload and poorly designed workstations. The chapter considers physical ergonomics, workflow design, cognitive support and stress management as complementary approaches to improving healthcare delivery. Safe patient-transfer techniques, adjustable furniture, accessible equipment and logically arranged clinical spaces are discussed. By reducing fatigue and occupational injury, ergonomic interventions can improve staff health, job satisfaction, patient safety, clinical accuracy and organizational efficiency while decreasing absenteeism and employee turnover.

Introduction

An entrepreneur is someone who starts or runs their own business. By having an equity stake in the company, the entrepreneur can profit greatly if things go well; however, they also take on a great deal of risk-far more than a regular employee of the company. Financial, career, emotional, and overall business risks are all examples of entrepreneurial risk. Because there is so much at stake in starting and growing a successful business, there are very specific skills that an entrepreneur usually requires to be successful. It could be a picture of a talented college dropout or a seasoned business professional with an uncanny ability to predict the next big thing. Replace whoever the persona is with ourselves. A successful entrepreneur does not have a specific demographic or personality profile. We can be entrepreneurs regardless of our age, race, gender, sexual orientation, socioeconomic status, or upbringing if we have dedication, drive, and essential business skills. Unlike personality traits and demographic information, entrepreneurial skills can be learned and practiced. If we want to pursue entrepreneurship, use this list to assess our strengths and weaknesses and determine which skills we need to develop before launching our venture.
