Elimination is what? What can be the elimination

Today in different branches of science very often use the same term, the meaning of which differs depending on the context. For example, assimilation, pressure, isolation, induction, elimination and so on.

The development of science has contributed to the emergence of the need to exchange information with the help of terms, since in this case the presentation of the material will be succinct and the formulations clear. However, very often new concepts are not found in dictionaries, so the expansion of the vocabulary is necessary. To expand the boundaries of human knowledge, began to use multi-valued terms. Today we will talk about one of them. It's about elimination.

What is the elimination?

Elimination is a multi-valued term. It can be found in many branches of science, for example, in mathematics, economics, pharmacokinetics, biology and so on. This word came to us from Latin. In Latin, the word eliminare means "cast out," "expel", and literally "kick out the threshold."

Elimination in pharmacokinetics

In pharmacokinetics, the term "elimination" means the excretion of drugs from a living organism by natural means.

There is a systemic and systemic elimination. Pre-systemic elimination is the removal of the drug at a time when the substance is still passing through various organs (intestines, lungs, liver, etc.), that is, until it enters the bloodstream.

Systemic elimination of a substance is its removal from the circulatory system.

Usually the biotransformation of the injected drugs is carried out in the liver, but it can occur in other organs and tissues. Special proteins (ligandins) that are in the blood are extracted from its plasma and bind in the cells chemical substances, which are then removed from the body.

Biotransformation is carried out in two stages. At first, some of the chemical compounds are converted into reactive metabolites, which form compounds with groups of endogenous substances. Such metabolites can accumulate in the body with repeated administration of drugs, which can lead to mutations, as well as cell necrosis or allergic reactions.

At the second stage, the body produces paired ethers with various acids and glycine. Appear compounds that dissolve well in water, poorly penetrate into tissues and are inactive.

Elimination factor

The coefficient (quota) of elimination is the daily loss of chemical compounds introduced into the body by removing the drug. This percentage is measured, it is constant for each drug.

Thus, in medicine, elimination is the natural removal of medications from a living organism.

Removal of the virus from the blood

Elimination of the virus is the removal of the virus from the patient's blood cells. Recently, more effective methods of fighting various viral diseases aimed at eliminating the virus after taking medications have been developed. The main goal of the development is not only to purify the body, but also to prevent the development of chronic forms of diseases.

Elimination in the economy

In the economy, you can also find the term "elimination", meaning the removal from production of certain products. Elimination of goods - is the cessation of its production, its withdrawal from sales, withdrawal from the market as such in connection with the loss of competitiveness, demand.

In order to identify those products that need to be eliminated, they evaluate the volume of sales, consider the place of the product on the market, its turnover in the company's turnover, capital, and its profitability.

Elimination of price fluctuations is the elimination of the swings of prices for certain products or goods.

Biology

In biology, elimination is the death of some individuals, organisms or their groups, populations, species due to different natural causes, that is, the influence of environmental factors. Most often these individuals are not adapted to the process of struggle for existence, are the weakest among the rest. Elimination in this case is expressed by the value of the inverse of survival.

The very death of representatives of a particular species is physical, when death occurs due to the impact of ecology, as well as genetic, when the genotype changes, which leads to a decrease in the number of offspring and their viability, to a decrease in their contribution to the gene pool of the next generation.

In biology, it is customary to distinguish two types of elimination: selective and indiscriminate (or general).

General elimination is the impact on individuals of external factors of very strong intensity, which exceeds the ecological flexibility of these individuals. As a result of all this, the class or species die out, regardless of their individual properties. Factors affecting the death of individuals exceed the possibility of their adaptation. This can include natural disasters or actions that have a human specific activities. In this case, there is no selectivity of elimination, but there is a possibility that the offspring of the individuals that are the most prolific will survive.

Elective elimination is the extinction of some part of a population that is least adapted to the influences of external factors as a result of the struggle for existence. In this case we are talking about the action of natural selection. Here the fittest representatives of the species survive.

Thus, the science of biology reveals the concept of "elimination", as elimination from reproduction of individuals or an entire species, their death due to the influence of various external factors, both physical and anthropogenic. Here, for example, you can include competition, natural selection.

Mathematics

In mathematics, elimination is the removal of an unknown quantity from a system of equations. There is such a thing in this science as the "elimination of quantifiers", which denotes a process in which one given logical formula generates another formula equivalent to it, one that is free from quantifier entries.

When the algorithm for eliminating quantifiers is possible, this is of great use for research. The ways of finding these algorithms for different theories have something in common, so you can talk about them as one method. If this method can be applied, it turns out to be quite useful, since it allows obtaining complete information about a certain theory. It also contributes to the emergence of a method by which one can determine whether a particular statement belongs to a particular theory or not. In other words, he proves that the theory is solvable.

There are some theories in mathematical logic where quantifiers can be eliminated: queuing theory, term algebra, Presburger arithmetic, dense linear order, atomless Boolean algebras.

Thus, the elimination of quantifiers in mathematics makes it possible to prove theorems, since it gives rise to a method for solving certain problems.

Sociology

In sociology one can also find the term "elimination". This word denotes exclusion from analysis or calculation of factors, attributes that are not connected by random connections to the process or phenomenon under study.

The term "elimination" is used in various sciences today, it has many meanings and interpretations, but it unites them one way: however, elimination is removal, elimination, exclusion, exclusion.
