6.1 Biodiversity

Biodiversity means biological diversity. It measures the variety of the earth’s animal, plant and microbial species; of genetic difference within species and of the ecosystems that support the species in its widest. Biodiversity is virtually synonymous with “life on earth”, this word was coined in 1985. Biodiversity is the degree of variety in nature and not nature itself.

The present era is rightly termed as an “Information era”. Therefore, information and wide access to it is considered as wealth. People want adequate and authentic information as early as possible. In recent years, information delivery system has been changed from old ways to the modern ways. At the present time information and communication technologies (ICTs) are increasingly being used as effective tool for reaching and delivering professional services among urban and rural communities. Yet the benefits of the information revolution are still much debated, particularly, in case of developing countries like India. There is a growing concern about the gap between the information “haves and have not’s”, which will continue to grow unless the developing countries acquire the infrastructure and resources to access these new ICTs.

Bonsai culture is an important branch of Ornamental horticulture. History of Bonsai is very old dating back to many centuries in China where it originated, as most Chinese arts and from there it spread to Japan and became highly specialized.  In fact, bonsai culture is in the present day more known as Japanese than as a Chinese art.  In Japanese homes, there are plants which are hundreds of years old. This treasured art is passed from generation to generation in Japanese society.

The word Bonsai is a combination of two Japanese words, Bon (meaning shallow pan) and Sai (meaning plant) which can be interpreted as ‘Tray planting’.  The idea conveyed is that of a small beautiful tree growing in a container as in nature with all its parts performing their natural functions throughout the times.  The artistic look of plant in a miniature form maintained for many years is the prime criteria.  Bonsais are grown outdoors and are displayed in living room, as and when, needed.  They cannot be treated as house plants.

Any deviation from optimum state could be referred as stress. Every living creature has to pass through one or the other type of stresses in life. Most of the farm animals including poultry suffer from various types of stresses. These include due to:

Adverse environment

Managemental practices

Diseases

Nutritional deficiency

Transportation etc.

Management of watershed in India

It involves management of water, land, energy and greenery, integrating all the relevant scientific approaches appropriate to socio-economic background for a pragmatic development of a watershed. In practice, it means allowing load free rainfall run off from the watershed. Clear outflow imply management of effective soil and water conservation and generating a lush green carpet in whole of the area. In other worlds, it is greening of a watershed through proper management of land, water and energy sources. The comprehensive development of watershed seems to make productive use of all its natural resources and also protect them is termed as watershed management.

The Banave terraces in Indonesia and those in Nepal, Mediterranean are examples of integration of human elements into a system of land management, which is an early achievement in watershed management. Watershed management is not merely anti-erosional and anti-run off approach but also a comprehensive integrated approach of land and water resources management. The approach is preventive, progressive, corrective as well as curative. Here wasted land resources could be fruit fully harvested into a productive face for rural development.

Introduction

The Government of India created a historic act, by enacting the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), the largest employment generating programme in the world, ensuring the right to work in a country with a population of over one billion. The Government of India passed the NREGA 2005, (Central Act No. 42 of 2005). NREGA was renamed as Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) on October 2nd, 2009. MGNREGA is the first ever law, in the world that guarantees wage employment at an unprecedented scale. This Act gives legal guarantee of at least one hundred days of wage employment in a financial year to a rural household, whose adult members volunteer to do unskilled and manual work. The Act is applicable in the Districts notified by the Government of India, the implementation of the Act calls for the formulation of Rural Employment Guarantee Scheme by the State Governments.

The key processes in the implementation of MGNREGA are the adult members of rural households submit their name, age and address with photo to the Gram Panchayat, which in turn registers households after making enquiry and issues a job card which contains the details of adult member enrolled and his/her photo. Registered person can submit an application for work in writing (for at least fourteen days of continuous work) either to Panchayat or to Programme Officer, who will accept the valid application and issue dated receipt of application, letter providing work will be sent to the applicant and displayed at Panchayat office. The employment will be provided within a radius of 5 kilometers and if it is above 5 kilometers extra wage will be paid. If employment under the scheme is not provided within fifteen days of receipt of the application, daily unemployment allowance will be paid to the applicant.

This chapter introduces the chemical nature of wool as a keratin-based protein fibre rich in sulphur-containing amino acids. It examines keratin structure, peptide and disulphide bonds, amino-acid composition, amphoteric behaviour and reactions with acids, alkalis, oxidising and reducing agents. The chapter explains the chemical basis of dyeing, swelling, felting, shrinkage and finishing treatments. Understanding these properties is essential for controlling wool processing while preserving fibre strength, appearance and functional performance.

7.1 Introduction

Organic polymers can play important role in ecosystems by accumulating biologically important elements and also by retaining soil moisture after aggregating soil particles. Extracellular polymeric substances (EPS) play an important role in cell aggregation, cell adhesion, and biofilm formation that subsequently protect cells from a hostile environment. Furthermore, certain polysaccharides from microbial sources are surface active, and thus attempts have been made to use them as metal chelaters, emulsifiers and flocculants in industrial and environmental fields/domain. Such use of microbial polysaccharides has infused renewed interest in its production and characteristics.

Integrated watershed management programme (IWMP)

The main objectives of the IWMP are to restore the ecological balance by harnessing, conserving and developing degraded natural resources such as soil, vegetative cover and water. The outcomes are prevention of soil run-off, regeneration of natural vegetation, rain water harvesting and recharging of the ground water table. This enables multi-cropping and the introduction of diverse agro-based activities, which help to provide sustainable livelihoods to the people residing in the watershed area. In addition, there is a Scheme of Technology Development, Extension and Training (TDET) is also being implemented to promote development of cost effective and proven technologies to support watershed management.

Till 1.4.2008, Department implemented 3 watershed programmes viz. Integrated Wastelands Development Programme, Drought Prone Areas Programme, Desert Development Programme. Since then, they have been brought under a comprehensive programme named Integrated Watershed Management Programme (IWMP) to be implemented under Common Guidelines on Watershed Development, 2008.

Drivers
• Unique aspects of the local climate and soil.
• Availability of resources and land labor.
• The current level of resource use.
• Economics of the proposed integrated farming.
• Farmer’s management skills

Sodium Clinical Significance Compared to potassium, sodium is distributed differently throughout the body. Due to the sodium pump mechanism, most sodium is extracellular. Compared to this, just 2% of potassium is extracellular; the remainder is intracellular. Regarding the plasma concentrations of sodium and potassium, renal function is the single most significant homeostatic mechanism.

Nephrology

Nephritis and renal calculi are the two major problems leading to renal failure in canine and feline nephrology. Chronic renal failure may occur at any age but it is more common in geriatric dogs. Congenital renal diseases may also lead to renal failure at any age. Chronic renal disease or chronic renal failure is a progressive deteriorating condition as compensatory mechanism (glomerular hypertension and hyper filtration) further deteriorate the condition. Hence chronic renal disease remains lifelong. For quality life, an early diagnosis of renal failure is very important. The following techniques are used to diagnose chronic renal failure.

Introduction

The classic bone tissue engineering paradigm highlights several key players: biocompatible scaffold that closely mimics the natural bone extracellular matrix niche, osteogenic cells to lay down the bone tissue matrix, morphogenic signals that help to direct the cells to the phenotypically desirable type, and sufficient vascularization to meet the growing tissue nutrient supply and clearance needs. The biomaterials are critical components in the bone-tissue engineering strategies, including polymers, ceramics, or their combinations applied in various forms, such as membranes and three-dimensional (3D) scaffolds. These materials typically mimic the extracellular matrix of bone tissue during the tissue regeneration process, providing mechanical support and a suitable environment for cell attachment, proliferation, and differentiation

Introduction
A microorganism or microbe is a tiny living thing that can exist as a single cell or in groups of cells. People have suspected the existence of these unseen microbes since ancient times. These single-celled creatures have caused serious infections that often led to deaths and illness. These microorganisms can spread quickly and cause big outbreaks of disease. In 1928, Alexander Fleming discovered the first antibiotic, penicillin. This discovery started the development of one of the most important groups of medicines in medical history. In the next three decades, many different types of antimicrobial drugs were developed. In his Nobel Prize speech, Fleming warned that using penicillin too much might one day lead to bacteria becoming resistant to it, which would be a major problem. Antimicrobial resistance (AMR) is one of the biggest public health challenges today. Many of the microbes that cause diseases, like bacteria, viruses, and protozoa, no longer respond to common antimicrobial drugs such as antibiotics, antivirals, and antiprotozoals. Antimicrobial resistance is when a microbe becomes able to survive and grow even when treated with medications that used to work on it. Antibiotic resistance is a type of AMR, but it only applies to bacteria becoming resistant to antibiotics. Resistant microbes are harder to treat, and doctors may need to use other medicines or higher doses. These options can be more expensive and have more side effects. Microbes that resist multiple antimicrobials are called multidrug resistant (MDR). Those that are resistant to almost all drugs are sometimes called ‘superbugs’. Antimicrobial prophylaxis is used by doctors to prevent infections, but it should only be used when it’s really needed to avoid unnecessary costs, side effects, and the development of resistance. Antimicrobial prophylaxis can be used to prevent a first infection or to stop an infection from coming back or reactivating.

Entrepreneurship Development
Entrepreneurship Development (ED) is a recent perspective in extension approaches. It attempts to integrate sociological nature of agricultural sector with capitalistic entrepreneurship. The terms like social entrepreneurship, corporate social responsibility and agricultural entrepreneurship have recently come in vogue. It is the most significant factor to bring about transformation of agricultural sector.
Theories of Entrepreneurship Development
The word entrepreneur is derived from a French root entreprenerd, meaning. to begin something, to undertake. Entrepreneur is a person with a high need for achievement [N-Ach] who is energetic and a moderate risk taker. An entrepreneur searches for change, responds to it and exploits opportunities. Entrepreneur is an innovator and dynamic agent of change, a catalyst who transforms increasingly physical, natural and human resources in a corresponding production possibility. Entrepreneurship is a means by which economy and society are transformed. The emergence of entrepreneurs in a society depends upon closely interlinked economic, social, religious, cultural and psychological variables.
Personality traits perspective of entrepreneurship
In this approach, the entrepreneur is assumed to possess a particular personality type and thus much research has been to enumerate a set of characteristics possessed. The main Concepts studied include innovativeness, dynamism, risk taking, creativity, alertness, need for achievement, aspirations, self-confidence and being ambitious. An entrepreneur is an individual who possesses qualities of risk-taking, leadership, motivation, and the ability to resolve problems. Entrepreneurial attitudes and behaviour also include openness to new information and people, motivation, making independent and self-directed decisions, the ability to see opportunities in a rapidly changing and uncertain environment, persistence, the motivation to achieve, technical know-how, taking ownership, personal integrity, accountable, capacity to manage and
organise.

To a layman, wasteland is a piece of land, which is lying uninhabited or uncultivated. These lands are also commonly perceived to produce much less than their potential. Depleted of the green cover and productivity, such lands are often in a critical condition. Broadly, wastelands may be defined as land where the production of biomass is less than its optimum ‘productivity. Wasteland also refers to lands, which are economically unproductive, ecologically unstable and subject to environmental deterioration.

What is Computer Network?

A computer network is a collection of computers and devices connected to each other. The network allows computers to communicate with each other and share resources and information. The Advance Research Projects Agency (ARPA) designed “Advanced Research Projects Agency Network” (ARPANET) for the United States Department of Defence. It was the first computer network in the world in late 1960’s and early 1970’s

Health care is an important way of making sure that rabbits stay productive. Every rabbit keeper should know how to recognize and, if possible, prevent and cure illnesses which can affect rabbits.

It is always better to prevent disease incidence than to let animals get ill and then try to treat them. Allowing rabbits to get sick is expensive for several reasons, sick animals stops growing and reproducing so money is lost with this decrease in production, some disease results in the death of rabbits, replacing the dead rabbits is expensive , treatment for the ill rabbits is usually expensive.

Mutations are sudden and heritable changes in the genetic material. They can result in deletion, inversion and translocation of certain portions in the chromosomes, which can result in the changed expression of a trait due to the interaction of alleles within or without the locus, sometimes the effects revert back or can be heritable.

Most of the fruit crops are highly heterozygous. However, heterozygosity is one of the advantages when it comes to mutation. In highly heterozygous crops wherein there is a need for improvement in a single trait, mutations have been of great use. One of main limitations is use of vegetative material, which due to the unlikelyhood of uniform penetration and distribution of mutagenic agent can result in chimera. Although hybridization and selection have made a fair dent in the improvement of fruit crops, mutation is one of the methods that can be relied upon to develop pre-breeding lines and to bring about change in the quantitavie traits. Another very important fact is that there are crops like grapes wherein a lot of spontaneous mutants have become established varieties viz., Sonaka and Saritha to quote a few. Some of the existing varieites wherein one or two traits need to be improved, mutation would greatly help in this in comparatively short time. In some of the crops like sapota, wherein the conventional breeding would take long time, mutation can be resorted to both for inducing variability in the germplasm as well as for trait improvement. It is also to be noted here that mutation breeding can be a good supplement for conventional breeding, more so with the emergence of tissue culture propagation, which often throws up spontaneous mutants. Mutation as a methodology can also be tried in some fruit crop spp where there is no disease resistance source within. It can also be adopted in cases where there is a need to break linkages.
