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’’.

Nutrient supply is one of the major inputs for agricultural crop production in a sustainable manner. The factor productivity of inputs especially the fertilizers in agriculture was found to be in a declining phase during the last four decades. This had a detrimental effect on annual compound growth rate of major crops as wells on soil quality. The current status of nutrient use efficiency in different cropping system is low in case of major macro nutrients likes Nitrogen (30-50%) and Phosphorus (15-20%). Because 50-70% of the nitrogen applied using conventional fertilizers, with particle size dimensions greater than 100 nm, is lost to the soil due to leaching, nutrient utilization efficiency (NUE) by plants is low. Attempts to increase the NUE in conventional fertilizer formulations have thus far resulted in little success. On the other hand, the emerging nano strategies indicate that, due to the high surface area to volume ratio, nano fertilizers are expected to be far more effective than even polymer-coated conventional slow-release fertilizers. In this context, nanotechnology offers an important role in improving the nutrient use efficiency of agricultural systems.

Introduction

Standard Plate Count (SPC) is used for determination of population of viable microbes. Enumeration procedures are based on the assumption that microbial cells present in a sample mixed with an agar medium form visible separated colonies. The bacterial colonies developed on the plates are counted. Each colony is presumed to have developed from one bacterium or clump of bacterial cells. Therefore, the results are expressed in colony counts per /ml of sample or colony forming units per /ml (cfu /ml). Total number of colonies counted on the plate multiplied by the dilution factor represents the number of viable organisms in a sample. SPC is a useful method for evaluating the microbiological quality at various stages of processing. It is also helpful in detecting the source of contamination in the product.

Introduction
This method is used to determine the ‘total bacterial count’ (living and dead  organisms) by direct microscopic examination in samples of broth culture, cell suspension and milk. Simple and Gram’s staining techniques are used to stain the cells. This method is simple and a rapid. A known volume (0.01 ml) of the sample is spread over a known area (1cm2) on a glass slide. The sample is allowed to dry; then stained and examined microscopically. The average number of cells per field is determined and is then calculated by applying microscopic factor.
Materials
1. Microscopic slide with one sq. cm. area marked
2. Breed’s pipette (0.01 ml)
3. Methylene blue or Newman’s stain
4. Culture of E.coli or Bacillus subtilis
Procedure
1. Measure the diameter of microscopic field with a stage micrometer using oil immersion objective and 10X eye piece.
2. Area of field πr2.

Method and Estimation of Generation Time
Introduction
Bacterial growth usually refers to reproduction-increase in population sizerather than to enlargement of mycelia cells. “Reproduction in bacteria occurs mainly through binary (binary means one cell becomes two) or transverse fission that results in the formation of two daughter cells. This is repeated at intervals by each new daughter cell in turn, or with each successive round of division. The population increases (Fig. 1). The time required for a complete fission cycle i.e. parent cell to two daughter cells is called the generation or doubling time. In bacteria, it is a doubling process in which each new fission cycle or generation increases the population by a factor of 2. So the parent stage consists of 2 cells, the second of 4, then 8, 16, 32, 64, 128, 256 and so on (Fig. 2). Thus the population will double, over and over again as long as the environment remains favorable for growth. The length of generation time is a measure of the growth rate of an organism. The average generation time in bacteria is 30-60 minutes under optimum conditions. Some species have very rapid growth rate and short generation time (5-10 minutes) and others have very slow growth rates and long generation times (measured in days). Staphylococcus aureus and Salmonella enteritidis, both causes of food poisoning, are examples of pathogens having relatively short doubling times of 20-30 minutes, which result in a few million cells from a few cells in a few hours in the infested food. The longest generation time occurs in species of Mycobacterium, particularly Mycobacterium leprae (the cause of leprosy) of 10-30 days as long as in some animals.

Introduction

Phosphate solubilising microorganisms include different groups of microorganisms such as bacteria, fungi and actinomycetes, which convert insoluble phosphatic compounds into soluble form. The species of Pseudomonas, Micrococcus, Bacillus, Flavobacterium, Penicillium, Fusarium, Sclerotium, Aspergillus and others have been reported to be active in bioconversion. Such bacteria and fungi can grow in media where Ca₃(PO₄) ₂, FePO₄, AlPO₄, apatite, bone meal, rock phosphate or similar insoluble phosphate compounds are the sole source of phosphate. Such microorganisms not only assimilate phosphorus but they also cause a large portion of soluble phosphate to be released in quantities in excess of their own requirements. The solubilisation is not restricted to calcium salts but iron

Introduction

As Rhizobia are slow growers so their enumeration by plating techniques is less recommended. Rhizobia can be enumerated in the presence of a large number of other organisms by most probable number (MPN) method. Soil containing Rhizobia is diluted in liquid and dilutions are used to inoculate roots of legumes. The presence of Rhizobia in a given experimental unit, inoculated by a given dilution, is indicated by the formation of at least one nodule on a root. Thus, the method involves the growth of legumes under conditions such that a single rhizobia cell can multiply and forms at least one nodule on the root.

Most Probable Number Method: This method permits estimation

Enumeration of microbial flora present in soil is done by dilution plating technique. The technique is based on the fact of diluting the source inoculums to the extent that after plating the known volume of inoculums on appropriate media, the colonies will appear in countable range and each colony will be assumed to have been derived from a single cell/colony forming unit. Three numerically dominant groups of soil microbes are bacteria, actinobacteria and fungi. The most commonly used culture media for their enumeration include

Nutrient Agar-for heterotrophic bacteria,

Actinomycetes isolation Agar or Kenknight and Munaier’s agar for actinobacteria

Martin’s Rose Bengal Agar for fungi.

The livelihood of millions of people depends on shrimp farming around the world, especially in tropical and sub-tropical developing countries. On the other hand, failure to protect the ecosystem and environment from degradation due to shrimp farming is a major concern. The long-term sustainability of this industry depends on its ability to be economically efficient, and at the same time to minimize environmental effects. Therefore, it is important to consider both the economic outcomes and various environmental effects in achieving a more sustainable industry. From this viewpoint, an attempt has been made to explore the key environmental aspects of shrimp farming in the world in general, and in Dhamara area in particular.

Impacts of shrimp farming are mainly in four areas, namely, land resources, water resources, forest resources and fishery resources.

Introduction
Health patterns were impacted by environmental changes. Aspects of human health, including quality of life, that are influenced by environmental physical, chemical, biological, social, and psycho-social elements are collectively referred to
as environmental health (WHO). It describes the theory and practice of identifying, addressing, preventing, and managing environmental conditions that have a negative impact on the health of current and future generations.
The illness rickets is caused by the overcast atmosphere, which blocks off sunlight and prevents people from obtaining vitamin D from the sun. In Europe, the air quality that suppresses smoke and turns mist into smog is the cause of both lung cancer and chronic bronchitis. However, fair skin types with low pigmentation are more susceptible to skin cancer in bright sunlight. Cold and moisture have been linked to rheumatism. Ruminant animals get infections as a result of the absence of trace elements in the soil. Humidity and temperature have an impact on disease vectors. Malaria, yellow fever, dengue, encephalitis, filariasis, and other diseases are spread by mosquitoes.
Types of Diseases
The following is a classification of the primary illnesses that people suffer from:
• Deficiency diseases: These are conditions brought on by a person’s diet lacking in certain vital nutrients, such as vitamins, minerals, or amino acids. For example: Vitamin A deficiency, anemia, rickets, osteomalacia, and gum and tooth disorders.

We are entering an era when certain environmental conditions will exert a degree of concern which has never been before encountered by man in the course of human history.

The survival of human beings depends on the realisation that they have to live in harmony with the various elements of the environment which are interconnected.
    
(i)     An understanding of the components and processes which takes place in the environment.
    
(ii)     The relationship between different abiotic and biotic components and the assessment of resources with reference to needs of people in a region is essential for their survival.
    
(iii)     A reduction in rate of growth of population in developing countries and a reduction in consumption of resources by developed countries would lead to a balance between population and resources. In this manner, the awareness of the problems faced by environment would enable people to take appropriate decisions. This makes the earth habitable for future generations.

Sustainable Development
Although the term “sustainable development” is frequently overused, it is essential to addressing a multitude of interconnected global concerns, including hunger, poverty, inequality, and environmental degradation.
Several environmental movements from previous decades gave rise to the concept of sustainable development. Major international gatherings, like the 1992 Rio Earth Summit, were crucial in advancing the cause of sustainable development. But it seems that progress toward sustainability has not been great up to this point.
Definition
A key objective of sustainable development is to achieve a reasonable and equitable distributed level of economic well-being that can be continuously perpetuated for many human generations. Sustainable development is defined as a pattern of social and
structured economic transmissions (i.e., development) that optimizes the economic and societal benefits available in the present without jeopardizing the likely potential for similar benefits in the future.
“Development that meets present needs without compromising the ability of future generations to meet their own needs” is another definition of it.
Salient Aspects of Ecological Development
1. It takes equity into account between nations and continents, racial and socioeconomic groups, gender, and age.
2. It encompasses environmental requirements as well as social development and economic opportunities.

Introduction

A society constitutes of several social system and institution such as family, school, religion etc. Every activity of these social systems and institution affect our environment in some way of other. There are various factor bring changes in the society. They are biology, environment, psychology, culture, demography and technology. All these factors collectively contribute to the changes in our society.

Auguste Gomte the father of sociology - defined sociology as the science of society. Sociologist believes that one can study society and understand the laws of society by applying the tools of natural sciences. We need to understand the nature as environment, its nature of work and our interaction with it, to understand and improve the efficiency of working with the nature. The Global deterioration the humanity is facing today is unprecedented in the annals of human history. We are already facing grave, water crisis disasters of all kinds, food, energy and ethical crisis etc. The solution is not visible and may not be visible in near future too. Environmental pollution means contamination in water, air, and land due to the various human activities. Man exploits natural resources to earn more and more profits. Forest is being cut down, the land is spoiled, and the air is becoming fuel and water being polluted. So nature has lost its balance such a situation has leaded us to what can be called as Environmental crisis. The changing lifestyle of our society is one of the main reasons for this crisis.

But unplanned execution of work and excessive industrialization and many other human activities has brought us to an alarming stage. In the face to live a luxurious life style we have been destroying the natural ecological balance.

ABSTRACT

In order to assess the baseline environmental status in the PTK mines the comprehensive primary data collection / survey programme was undertaken during the period i.e. from April 2003 to June 2003. The environmental monitoring for ambient air quality, water quality, soil quality, noise levels, dust fall, traffic density, meteorology of the study area, etc was carried out. Detailed satellite image interpretation was carried out and thematic maps of the study area were prepared by visual interpretation using tone, texture variations from IRS –IC LISS-III – False Color Composite geo coded images. Digital image processing techniques (supervised classification) were used to classify land use, geology, geomorphology, and drainage pattern/ watersheds and soil cover of the study area. Detailed flora and fauna study was carried out in the study area comprising of core and buffer zones for identification of existing species. The description of baseline environment in the study area is given below.

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.

3.1 Introduction

India, when gained independence in 1947, was predominantly an agrarian economy, with a stagnant national income. The country inherited a weak industrial base, restricted to only a few industries. Agricultural growth was virtually negligible, the country had a stagnant cropped area where by only a very small proportion of agricultural land was irrigated. On the eve of the country’s independence, on 15^th August 1947, Jawaharlal Nehru, India’s Prime Minister, reminded the country that the task ahead included ending poverty, ignorance, and disease and inequality of opportunity. India began the process of planning with the launching of the 1^st five-year plan in April 1951. The central purpose of planning was to ‘initiate a process of development which would raise living standards and open out to the people new opportunities for a richer and more varied life’. Afterwards, the five-year plans were formulated seeking development in a sustainable manner.

The country, over the past has travelled a long way indeed in its drive towards economic growth, modernization of the economy, feudal economy at the time of independence has been transformed into one based on a fairly developed and diversified industrial structure and a sound agricultural base with a large potential for further industrialization and development. The income and consumption levels of people, on an average, have increased and the consumption basket has diversified. A noteworthy achievement indeed has been the elimination of famines with which the country continued to be afflicted right until independence. That achievement is far from negligible since many other countries in Asia and Africa are yet to free themselves of this malady. There is also other achievement, varying from the successful functioning of a democratic system to the emergence of a strong and large scientific community (Dreze Sen, 1995). The figure 3.1 shows the per capita income during 1997-1998. It shows that the maximum income from Northern India compared to Southern India. However, having adapted the pattern of economic development that brought prosperity to the Western, India has also seen widespread environmental damage and degradation in the pursuit of economic growth. The concern for preserving the environment against the onslaught of industrial expansion, intensification of agricultural, and adoption of a resource-intensive lifestyle has not been given the attention it deserved, and the costs of environmental degradation have not been internalized in the development process. While the Indian economy study made by two World Bank staffers shows that the country is paying an enormous price for this onward march, which has brought in its wake ecological devastation and numerous health problems.

The complex interplay of biotic, chemical, and physical forces that shape an organism’s structure and survival within an ecological community is known as its environment. The “backdrop” to the story of human history is the environment, which includes the “wilderness” that humans have not yet domesticated or subjugated, the “hinterland” that surrounds human settlements, and the habitats and resources that humans exploit.
Everything that exists naturally on Earth or in a particular place, both living and nonliving, is included in the natural environment. The lithosphere, crust, upper and lower mantles, inner and outer cores, and other layers make up the structure of the earth.
Every living thing, including non-living ones, interacts with every other thing constantly in its surroundings. People in particular need an environment to survive. Humanity and the environment are mutually dependent. The state of the environment is greatly impacted by human activity, and this has an effect on how our civilization is developing as a whole.
