Anorexia in dogs with heart failure is very important clinical sign of concern as continued anorexia leads to weight loss and cardiac cachexia. Cardiac cachexia in dogs is the main reason that contributes to an owners’ decision to opt for euthanasia. It is therefore much more important to understand the various factors that lead to anorexia in dogs having heart failure. 

Heart failure is the end stage of cardiac diseases. It occurs in pet birds when cardiac output is insufficient and unable to maintain arterial blood pressure. In birds right side heart failure is more common as compared to left heart failure.

The application of (VCRS) Vapour compressor refrigeration system is in the air conditioners (window, split, central or precision), car air conditioners, domestic refrigerator etc. The different parts of a domestic refrigerator are: in the hermetical sealed compressor, air cooled condenser, capillary tube, thermo expansion device, filter, rotameter, solenoid valve, temperature control sensor.

Thermal stress arises whenever there is some increase or decrease in temperature of a body which causes either expansion or contraction in the dimension of body. If body is free to expand or contract, with the rise or fall of temperature, there exist no stress in the body. But if deformation of the body is partially or completely resisted then stresses are set up in the body which is known as Thermal Stress. However amount of stress induced in partially prevented deformation will be small than in case deformation is totally prevented.

The initial symptom of Alternaria brassiciola appears as small, dark colored spots which enlarge rapidly to form circular lesions. Under humid conditions a bluish velvety fungal growth is seen in the centre of these spots. Spots caused by Alternaria brassicae are almost similar to those produce by Alternaria brassicicola but are comparatively smaller and lighter in colour. When many spots are formed on the leaves, the leaves turn yellow and dry prematurely. Formation of pods and seeds are adversely affected.

It is a very common disease of mango. It is otherwise known as blossom blight, leaf spot, twig blight or wither tip.

The disease attacks all the growth stages of plant affecting all above-ground parts. Plant covered with powdery patches leads to distortion, malformation and discolouration of leaves especially young leaves. Powdery patches gradually turn to grey and fi nally dark colour. Affected fl ower fails to develop fruit. Young berries turn black, irregular in shape and develop cracks. Sometimes berries ripe partially and rot. Vines get wilted.

It is a serious disease of apple which not only reduces the quality and size of fruit but also cause premature fruit drop and defoliation. Fruit loses its marketability due to poor quality. It also reduces storage time and cause loss up to 70%.

In light of the high population of nematodes, N.A. Cobb (1915) who is considered to be the father of American Nematology, provided a dramatic description of the abundance of nematodes. He stated, “if all the matter in the universe except the nematodes were swept away, our world still would be dimly recognisable.

Potato is one of the most important vegetable crop grown in India. It thrives best in cool climate. Therefore it is a summer crop in the hills and a winter crop in plains.

In general, germination of onion seeds is poor, and, in the case of old seed stocks, this problem is severe. Seeds soon lost viability in the ordinary storage state. However, cold storage conditions significantly increase the viability of seeds.

In several cucurbits as well as other crops, BER is a physiological condition found (for example, tomato, brinjal and pepper). It typically occurs as a general rot at the flowering end of rising fruit. Usually, the blossom end rot is the result of inadequate or uneven irrigation, high humidity, or other variables that slow the flow of water through the plant. Slow water movement may also result in temporary calcium deficiencies leading to blossom end rot as calcium is added into the plant with the transpiration stream.

This is one of the most serious difficulties in mango farming since it makes mango agriculture less rewarding for farmers. In one year (a year) and very little or no harvest next year, mango trees appear to bear huge crops (off year). This bieniality is therefore also present in normal ranges (Singh, 1990). 

Ordinarily, fruit bears a single crown, but fruit bears more than one in some cases. The top of the fruit will therefore be smooth and wide and the fruit will not be ideal for canning. These fruits have an insipid taste and are corky. It is intended to be an inherited character, often found in the Cayenne group to which the Kew variety belongs.

A well planned projects requires pre-feasibility study to explore the opportunity to find out problems, avenues of co-ordination etc. A government being a regulation spells out priotize for national and regional economy and by the frameworks for resource allocation.

It is a process by which a act of predetermined activities is carried out in a planned manner, with a view to achieve certain establish objectives.

To implement a project means to carry out activities proposed with the aim to achieve project objectives and deliver results and outputs. It is a highly complex process and it involves a relationship among several system and variables

ACID SOILS: Acid soils with pH below 6.5 are widespread. Main limitations of these acid soils are low pH, low CEC, low status of bases, especially Ca, Mg, and K along with toxicity of Al and Mn. Use of acidifying fertilizers aggravates this situation.

The aim of any good zoo should be to recreate the habitat from which the animal came as accurately as possible, with enough space to move around and enough stimulation so that they can behave naturally. Monkey cages should have plenty of branches for them to swing from and bird cages should have enough room so that they can fly. Some zoos hide the lionís or tigerís food so that they have to use their senses to explore and find it.

Wildlife Sanctuary is a natural habitat, owned by the government or private agency, that safeguards particular species of birds and animals to make sure that viable population of the wildlife and their habitats are maintained.

Amounts up to 5 ml of blood can be safely drawn from the auricular marginal vein, using a 23- to 25-gauge needle (or) a 23-gauge butterfly attached to a syringe or tube. The jugular vein should be avoided for blood collection if the rabbit suffers from a respiratory problem or shows respiratory distress. It may become cyanotic during the procedure. Alternate sites for blood collection are the cephalic and the lateral saphenous veins. (Their locations are the same as in dogs and cats. These veins are fragile, and a hematoma is easily formed).

Barley is believed to be originated from Asia and Ethiopia. Its Sanskrit name ‘Yava’ is mentioned in ‘Veda’ and use of barley in religious ceremonies has been described which shows that barley has been grown in India since ancient times. It is widely believed that the ‘Near-East region’ is the probable place of origin of barley around 8000 BC (Harlan, 1968). There are two theories regarding the origin of barley. 

Jaggery making is a simple process comprising crushing of sugarcane for juice extraction, filtration and boiling of juice for concentration and then cooling and solidifying to give jiggery blocks.

Mints are a group of perennial herbaceous plants, belonging to the family Lamiaceae: Labiatae, which yield essential oil on distillation. The various species of mints which are commercially cultivated in different parts of the world are: Japanese mint or corn mint or field mint (Mentha arvensis subsp haplocalyx Briquet var. Piperscens Holmes var. Javanica), peppermint (M. Piperita L.) spearmint or garden mint or lamb mint (M. spicata L.) and bergamot mint or orange mint (M. citrata Ehrh.)

Seed is a basic input to raise the crop plants. Healthy seeds produces the healthy crop. However, the seed carries different pathogens either externally or sometimes internally in the seed to affect the seed emergence and healthy seedling growth. Therefore, the seed treatment with fungicides/bactericides, based on the infection of the pathogen, is highly essential to counter the attack and infection of these pathogens to the germinating seedlings.

Many chemical and visual lures attract insects and therefore can be used as attractants to monitor or directly catch and reduce insect populations. These attractants are used in ways that do not injure other animals or humans or result in residues on foods or feeds, and can be used in an environmentally sound manner in pest management programs.

Grape is one of the important fruit, crops being grown in area of 79.6 thousand hectare with annual production 1878.3 thousand MT. India is a major exporting country of grapes, it exported fresh grapes 24633.79 MT (2018-19) (Anonymous, 2018).

Identification of key communicators
For effective introduction of innovations and transfer of technology among farmers, effective communication is the prime need. An extension worker passes his information more effectively if he communicates with farmers/livestock owners through local leaders and key communicators.
Leader:  Is a person who effectively influences a group to cooperate in setting and achieving the goal.
Leadership: Leadership is a process by which an individual influence, guide and direct the thought, feelings and impressions in desired way.
Key communicators: Key communicator is a person who has maximum information about his society and vicinity area on different aspects.

Cluster Sampling (Meaning and Concept)

Cluster sampling is a special type of sampling which is used when we have to make a large survey such as a survey for the whole country and whole state etc. to know the privilege. Under this method, the total population is divided into some recognizable subdivisions known as clusters. Out of all the clusters, a given number of clusters are chosen at random. All the items covered by the selected clusters are included in the sample.

A sampling technique in which we divide the whole population into groups or subgroups in such a way that there is heterogeneity within each group and homogeneity among the groups and then a simple random sample of n groups is selected from a total of N groups of population and finally all the units of selected clusters from our sample.

Non-Probability sampling methods are also known as non-random sampling methods or deliberate sampling. These types of methods are reliant on the researcher’s ability to select members at random. These sampling methods are not fixed or pre-defined selection processes making it difficult for all elements of the population to have equal opportunities to be included in the sample.

Types of non-probability sampling techniques

1. Judgmental or Purposive sampling

This technique involves the purposive selection of units of samples based on the judgement of the researcher. The researcher selects the sample on the basis of his a priori knowledge and experience.

Yet now we have discussed probability sampling techniques in which sampling units are assigned with equal probabilities. But sometimes in practice if want to draw a sample with unequal probabilities i.e., every sampling unit is assigned with varying probabilities and we draw a sample from these units with the help of equal probability methods, then the results are not as much efficient as compared to unequal probability sampling.

Simple random sampling is a procedure wherein the chance of selection of every unit in the required sample is equal. However, the use of simple random sampling is not advisable when the units differ substantially in size as the significance of unit size is ignored.

The basic idea of this type of probability technique is that chance of each unit of a population being selected in the sampling is proportional to its size. The units vary significantly in size and the variable under study is largely related to the size of the unit. Therefore, the probabilities fixed for each unit are proportional to their sizes.

In our previous chapters, we have discussed various sampling designs or techniques such as simple random sampling, stratified sampling, systematic sampling and cluster sampling recently we have discussed unequal probability sampling i.e., probability proportional to size sampling. In all these sampling designs the variable of interest (generally there is only one variable of interest) which we have considered and perform our estimation based on that single variable. There are some other variables which are related to our variable of interest and if we utilize those variables, we may gain some efficiency in our estimator i.e., if we take some correlated variables with our variable of interest or study variable by this, we can enhance our estimation. The variable which is correlated with the study variable is usually known auxiliary variable or supporting variable or supplementary variable or benchmark variable. This auxiliary variable is utilized in two stages either in the design stage or estimation stage.

Graunt (1662) was the first who used auxiliary information to estimate the population size of England. After this Laplace used auxiliary information for the estimation of the population in France.

Non-Response

Non response occurs when respondents are not available or do not occur in the survey and refuse to respond by any means. This non response is mainly of two types either item non response or unit non response.

If we are conducting an online survey and mailing a questionnaire to various persons. But sometimes we get a reply for some questions and sometimes not i.e., in case of questions in which income is concerned. In some cases, the mail is ignored due to lack of time. So, if the whole questionnaire is ignored by any means, then it is known as non-response and if some of the questions are ignored due to their fussy nature such type of response is known as a unit non response. Such types of non-response problems are very common in surveys. Whenever we carry out a survey non response always exists because it is almost impossible to get every response from each individual.

The individual chosen for the sample is not ready to participate in the survey is known as non-response. This type of selection bias is unit/item non response.

Agriculture economics is the study of how resources are used, distributed, and utilised in order to create agricultural products. A consistent level of farm surplus is one of the sources of technological and commercial expansion, so agricultural economics has an impact on the economics of development.

In general, it may be said that average salaries are low when a sizable portion of a nation’s population depends on agriculture for a living. It is more accurate to argue that a country’s majority of people must rely on agriculture because it is impoverished rather than that a country is poor because the majority of its population works in agriculture.

Features of Agriculture

Agriculture is the principal industry of employment. Nearly 61 percent of the whole population is employed there. It makes up 25% of the country’s income.

Monsoon dependence: The monsoon is crucial to Indian agriculture. The production will increase if the monsoon is good, and the crops will fail if it is below normal. Floods can occasionally ruin our crops. Agriculture depends on the rainfall since irrigation systems are so poor.

Supply

Supply refers to the good being sold at a specific price and moment.

Supply is the quantity of a commodity that is actually made available for purchase at a specific price and moment. The various quantities of a commodity that would be available for sale at varying prices are referred to as the supply schedule.

Supply schedule of Rice The supply schedule for the whole market is called market supply. It is arrived at by adding the quantities supplied by all the sellers at varying prices. The increasing portion of the marginal cost curve is used to create

Macroeconomics approaches the economic problems in terms of aggregates like national income, general employment level, aggregate demand, aggregate production and so on. The important among the above is national income. The one common thing to all products is value. Therefore, the national income must be expressed in monetary terms. The entire value of the goods and services (output) produced by an economy over time is measured by national income (normally a year). It also serves as a measure of the money generated by production and/or the total amount of expenditures made in order to produce the output.

Significance

The Central Statistical Organization of India has been calculating the country’s gross domestic product. We can measure your academic performance in relation to other students by the percentage of the marks scored by you. Similarly a country’s economic performance has been measured by indicators of national income such as GDP or GNP. Additionally, it is crucial to measure national income for a number of reasons, such as making predictions about how the economy will develop in the future,

Theories of Population

The theory of population is studied because the supply of labour depends upon population and its growth. Observing the abnormal growth of population and consequent fall in the standard of living, Thomas Malthus (1760-1834) an English Clergyman frst studied population growth in various countries of Europe. Later he wrote a book entitled “An Essay on the Principles of Population” in 1798. His his theory is popularly known as Malthusian theory of population. To quote the theory in his own words “By nature human food increases in a slow arithmetic ratio, man himself increases in a quick geometric ratio unless want and vice stop him”

Money

Money has made rapid economic progress possible in this modern age. In the early stages, exchange took the form of barter The direct exchange of one good for another is known as barter. For instance, the potter received paddy from the farmer in exchange for cooking pots. Barter became more challenging as there were more items to trade. Silver and other precious metals were thus utilised as currency. Then the paper currencies were used as legal money, i.e., an instrument of exchange, by the governments.

Definition of Money

Anything that the general public readily accepts as payment for products, services, other assets, and the discharge of debt is referred to as money. Robertson defned money, “as anything that is acceptable in discharge of obligations”.

According to Crowther, “Money is anything that is generally acceptable as a means

Definition

‘Whipping agent’ are a wide variety of materials to describe their role in confectionery manufacture as a means of holding air introduced into a product, to produce a uniform dispersion of air cells within the confection leading to a lower specific weight and considerable modification to the texture.

Stable foams cannot be obtained by whipping high concentration sugar solutions without the presence of a ‘surface-active’ agent.

Many types of proteins have whipping properties and those used in the sweet industry are:

(a) Egg albumen, crystal powdered and spray dried;

(b) High Bloom gelatine and gelatine hydrolysates;

(c) Skimmed milk in spray dried form;

(d) Whey, or whey in a mixture with skimmed milk;

A glucose syrup is defined as ‘A purified and concentrated aqueous solution of nutritive saccharides derived from starch’, and having the following characteristics:

1. Dry matter of not less than 70%.
2. A dextrose equivalent (DE), expressed as d-glucose, of not less than 20% based on dry matter.
3. A sulphated ash content of not more than 1% on a dry basis.

Starch has a DE value of zero, whilst dextrose, the final end product of starch hydrolysis, has a DE value of 100. For the lay person, the term dextrose equivalent or DE can be regarded as an indication of how far the conversion process from starch to dextrose has gone. While technically DE is a measure of the total reducing sugars present in a glucose syrup.
