In this article we propose a method that uses the apparatus of the theory of fuzzy sets, together with the five-factor model of Altman in assessing the creditworthiness of an enterprise. Altman's model works in two ways: It applies the root mean square (RMS) integral approximation for the exact calculation of quantitative assessment of creditworthiness (probability of bankruptcy), and using the device of fuzzy sets for ordered sets by the degree of confidence in the resulting probability. In this paper we conducted simulation procedure for the credit assessment and showed the capabilities of the model. The model input parameters , forms system inputs (input variables), allowing you to get the value of the parameter z of Altman. With the help of Altman's model, approximating function L6, the decision function I(p) and the algorithm for calculating preference we obtain the number of the set i to which belongs a number of ordered sets as fuzzy logic . On the selected simulation parameters, stable statistics can be obtained. Altman's model with the use of computational function allows real values of the input parameters of the enterprise replaced by random values of the simulation model. This technique allows, as shown by the results of computational experiments, the creditor to obtain additional information on the creditworthiness of the investigated enterprise and make a more informed conclusion about its financial condition, which speeds up the decision on the possibility of issuing the required credit. The development of method of estimating fuzzy logic can be applied to other models of assessing the creditworthiness of a company: Davydov's model, Zaitseva's, Saifullina's, Kadykova's and others with appropriate modification
The article presents results of the study of lavender reproduction (Lavandula angustifolia Mill) with methods of generative reproduction (seeds), vegetative reproduction (cutting, layening, divide of buch), clonal microreproduction using the culture in vitro.
The method of cloned microreproduction based on the culture of the isolated meristems which provides genetic identity of regenerated plants to initial forms and high coefficients of reproduction, improvement of landing material from fungal and bacterial infection, and also release from viruses at a combination with methods of thermotherapy and a chemotherapy is the most effective for the solution of objectives of seed farming of a lavender. As a material for carrying out researches we had plants of lavender (Lavandula angustifolia Mill), Sineva sorts, Stepnaya and perspective selection samples 337-9 and 310-17. Apical meristems 0,2-1,0 mm high isolated from top and axilary buds of a stalk of annual plants have been used as explant. Murasige and Skuga (MS) used as a basic nutrient medium for cultivation of the isolated meristems. Explants have been cultivated in the cultural room with 25-26 0C - temperature, lighting – 2-3 lx, relative humidity – 60-70%. It has been established that both April and October are the best month for isolation of meristems correspond calendar to phases of spring and autumn growth at the lavender donor plants and that optimum is an agar nutrient medium of MS, added with kinetin (1,0 mg/l) and GC (1,0 mg/l); frequency of regeneration of all studied genotypes was 90,0-100,0 %. Feature of morphogenesis of lavender meristems in vitro culture was already at the first stage of clonal microreproduction as there was a multiple shoot formation. Studying of features of development of lavender microplants during ten passages also was carried out, as the level of stability of regeneration processes throughout several cycles of a miсrograftage is one of important factors on which efficiency of microreproduction depends. We have also shown, that the efficiency of reproduction remains at the stable level of the sort named Sineva and sample #337-9 to the 8th passage (1:7,77-12,45 and 1:7,60-11,85 respectively), at the variety called Stepnaya - to the 7th passage (1:6,10-11,81), at the sample #310-17 - to the 6th passage (1:6,17-8,37)
This article is devoted to treatment effects of cuttings
of a grape variety called Moldova with 0.01% solution
of heteroauxin on their regenerative capacity,
depending on the light conditions. We have established
that the germination of cuttings in the dark, as well as
the treatment of heteroauxin significantly stimulate
their regenerative abilities. The length of the shoots,
regardless of the use of heteroauxin, depends on the
mode of the light produced during the germination of
cuttings. In both studies, the length of the shoots on the
end of experiment cuttings germinated in the dark, was
1,71-2,66 times more than when germinated in the
light. Cuttings rooting ability also largely depends on
the light produced in their germination. In both studies,
the rooting of cuttings started earlier and passed more
rapidly during their germination in the dark.
Processing cuttings with heteroauxin, followed by
germination in the dark, speeded up the formation of
roots even more, compared with the case where the
cuttings treated with heteroauxin germinated in the
light. In the best case rooting increased by 42,5-47,5%,
the number of roots on basal ends of cuttings in 18,3-
18,5 times, the numbers of cuttings with 3 or more
roots to 72,5-80,0%

Spraying the hatching eggs with disinfecting solution was found to be the effective mean to decrease a risk of bacterial contamination. The most used disinfection means contain quaternary ammonium compounds, phenols, iodine of glutaric aldehyde. However, some disinfectants have ability to close pores on to the egg in case of applicating on the surface of egg that results in decreasing evaporation of water during incubation and decreasing hatching. The most popular methods is gazation with using the preparation on a base of formaldehyde, formalin, potassium permanganate. The above-mentioned methods have the risks of potential danger for hatching eggs and developing embryos. For biocidic treatment of eggs YF-irradiation is used, as well as ozone, but it penetrates into eggs owing to eggs pores and destabilizes embryo. Moreover, ozone possesses the toxic, corrosive and inflammable properties and its using must be controlled. Some disinfectants, especially chloral-containing preparation have a property to react with cuticle of eggshell and falls their activity. Other disinfectants, as a rule, block the pores and make difficult gazoexchanging. Using the preparation on a base of electroactivatel solutions of sodium chloride. Was detected to be one of the perspective approaches to disinfection of hatching eggs. The results of study on a development of disinfection technology for hatching eggs contaminated by bacteria and fungi with using the Super ANK Anolyte
Under the field conditions breeding the young poultry takes place in the eggs out of maternal body. For successful breeding the progeny keeping all the demands to safety and quality of hatching eggs has the important significance. Safety demands are presented in the appropriate Technical Standards (TS). The microbial standards are to be very significant. Moreover, it is necessary to control both the microorganisms note in TS and other species as dangerous factors on during the process of production. The methods and means used presently for disinfection of hatching eggs have some disadvantages, e.g. the method of gazation with using the preparations on a base of formaldehyde, formalin, potassium permanganate; ozone has the toxical, corrosive and inflammable properties and its using must be controlled; chlorine-containing disinfectants have a property to react with cuticle of eggshell and fall their activity. The results of a study on applicating Super ANK Anolyte for biocidal treatment of the eggs are presented in the article
