The problem of integral geometry in a strip with weight function

In this work we consider the problem of reconstructing a function from a family of parabolas in the upper half-plane with a weight function having a singularity. The uniqueness of theorem for the solution of equation is proved and the inversion formula is derived. It is shown that the solution of the problem posed is weakly ill-posed, that is, stability estimates are obtained in spaces of finite smoothness

Prevalence of Ecto-and Endoparasites in Animals

The article presents information on the spreading of common pest ecto- and endoparasites among farm and laboratory animals, as well as in the areas of livestock farms

Ways to control asynchronous motor with phase rotor of mining machines

The article describes various methods of controlling asynchronous motors with a phase rotor. To solve the problems of controlling speeds and moments in a modern electric drive, two main methods of frequency control are used: scalar and vector. Advantages and disadvantages of scalar and vector control, voltage dependence are given

Analysis of organic solvents released during painting and drying of automobiles and household products

The article presents the results of a study of the drying process of paints and varnishes based on organic solvents. and environmental problems. An analysis of the current scale of their use is carried out and an assessment is made of environmental problems associated with their evaporation. The issues of organizing the collection of the resulting solvent vapors and their further use, taking into account their use in specially equipped rooms, are considered

Forming neuroendocrine apparatus of lung in ontogenesis

Aim of the research is to show the developing legitimacy APUD-system of lungs in pre and post ontogenesis. Condition of neuroendocrine apparatus of lungs on rabbits was studied during the fetal embryogenesis of inner development and after 1-180 days of the birth. Duration of the research on rabbits was chosen according to their changing afterbirth features as physiological function of organism; was selected the periods of newborn stage, enlightenment, complication of locomotion, pre-pubertal and pubertal. Materials were fixed by immersion in liquid of Buena. After suitable wiring, the material was flooded in paraffin. Histologic shears were colored hematoxylin and eosin, stain of Van –Gieson, resorcinol-fuchsinol of Veingeirt. For detecting endocrine cells of shear impregnated by the method of Gremeluise. Luminescent histochemical research was done with the help of V.N. Shvalyova and N.N. Juchkova method with applying glyoxylic acid on fresh-iced shears. For defining, the amount of fluorescent monoamine (serotonin and catecholamine) was used microfluorimetry. However, the intensification of histogenetic processes occurring in the organ after birth due to the expansion of physiological functions is accompanied by an increase in the number of apudocytes and NET. The content of catecholamines and serotonin in neuroendocrine structures depends on the period of growth and differentiation of the lung: during the intensive growth of the respiratory organs in the fetal period and in newborns, the level of catecholamines in apudocytes and NET is increased; with the predominance of differentiation processes in the neuroendocrine apparatus, the serotonin content increases

Integrated pest management of Tuta absoluta: practical implementations across different world regions

The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), has invaded most Afro-Eurasian countries and is threatening worldwide tomato production. Various strategies have been developed and implemented to manage this pest. Here, we present a timely review on the up-to-date development and practical implementation of integrated pest management (IPM) programs for tomato crops across different world regions infested by T. absoluta. While insecticide resistance is a growing concern, biological control via releasing or conserving arthropod natural enemies and sex pheromone-based biotechnical control are the most successful management practices. Agronomic control-related research is an emerging area where the soil fertilization and/or irrigation, as well as breeding of resistant cultivars, has the potential to enhance IPM effectiveness. Grower survey responses in the native areas (i.e., South America), early-invaded areas (i.e., first report between 2006 and 2012) and newly invaded areas (i.e., first report after 2012) showed that the control programs evolved along with the areas and time since invasion. Growers in the early-invaded areas shifted more rapidly from chemical control to biological control compared to those from the native area. In all concerned regions, the pest control failure risk following chemical insecticide applications and the high cost associated with either biological or biotechnical control methods have been the greatest concerns for growers. The information gathered from the native and/or early-invaded areas may help achieve a more effective management in newly invaded areas. Lastly, researchers are expected to break the bottlenecks of some key issues that would enable lowering application cost of novel biorational alternative management options

The Last Tendencies of Liberalization of Labor and Employment Legislation of the Republic of Uzbekistan

The article discusses the need for a new edition of the Labor Code of the Republic of Uzbekistan and its impact on the development of business and investment activities in the country. Debating questions which the new edition of the Labor Code will change the current edition are analyzed. In particular, various solutions are proposed in relation to various kinds of disputable situations between employees, business representatives and the state, arising in the sphere of social and labor relations.In order to there is no unified approach to adoption of the Labor Code in a new edition, first, it justifies the need for drafting of concept. The most important ideas that can form the basis of the Concept of the Code are analyzed. Scientists' opinions are being studied on improving the code. In addition, the impact of the adoption of the new Labor Code on the economy, based on the analysis of the role of the importance of the new Labor Code adopted in some foreign countries (Georgia, Kazakhstan, Tajikistan) in the development of entrepreneurship, is predicted
