Abstract Factors affecting biological variation in total cholinesterase activity in plasma were studied in a population of 3372 apparently healthy subjects at least four years old. Determination of the dibucaine number, after inhibition of the activity by dibucaine, made it possible to specify the contributions of genetic and physiological characteristics to variations in the total activities by using a statistical method of segmentation. The main factors modifying plasma cholinesterase activity in males are genetic status (dibucaine number) and degree of overweight (subscapular skinfold). In females, hormonal status (puberty or menopause), genetic status (dibucaine number), and the use of oral contraceptives are the factors mainly responsible for the variations of plasma cholinesterase activity. These data allow us to propose reference limits for total plasma cholinesterase.

Recently, more and more people are paying attention to healthy lifestyle, including nutrition, giving preference to natural products. One of these products is honey. The chemical composition of honey is represented by a large number of nutrients: easily digestible carbohydrates, amino acids, enzymes, minerals, vitamins, organic acids, causing its nutritional, dietary¬, and medicinal properties. In the article, the authors analyzed the state of honey production in the country, reflected the share of imports in the market and the share of exports in production, the main factors affecting the honey market are investigated. Based on the results of studies of honey from different regions of the Russian Federation and the requirements of international legislation on product safety, the authors have developed proposals to improve the competitiveness of hive products, both in domestic and foreign markets.

The Relationship

The Malaysian Property Market Report 2016 reported that Malaysian properties transactions were down, office occupancies were down, and simultaneously unsold units were up. Almost two thirds of the total homes that developers launched remained unsold, comprising 90,491 units at the end of 2016 including of those completed, under construction, and not constructed. In recent years, the declining phenomenon in the property market is getting worse apparently. The reason behind this situation is mainly due to the rising cost of living which causes the purchasing power to be weakened; therefore, to buy a property or even goods for daily use has become difficult as the overall spending power of the Malaysians has decreased. Determining the important factors that impact upon the decision making of the house purchasing process could develop a better understanding for both buyers and home providers which eventually could avoid the ‘unsold’ properties scenario in the market. Hence, the objective of this research is to evaluate the relationship between the three main factors identified which are financial, location, and neighbourhood towards the housing preferences of homebuyers in Kuala Lumpur. A total of 100 respondents, ranged between 25 to 34 years old, responded to the survey, and the results were derived using the multiple regression analysis. The results favour the locational factors that contribute significantly to the determination of a buyer’s preferences when purchasing a house.

Objective. The objective of the study is to determine the requirements for various devices of hydraulic reclamation machines, which are widely used in the construction of canals and drains, to maintain a given slope, as well as the calculation of the executive mechanism that serves to eliminate the oscillating movement of the working body relative to the line of the specified slope.Methods. A mathematical description of the vibrations of the working body for caterpillar hydraulic reclamation machines with mounted working bodies is given.Results. The article presents the results of research to identify the main factors affecting the oscillations of the working body of caterpillar reclamation machines. As a result of theoretical and experimental studies, it was found that when a caterpillar machine with a rigid undercarriage crosses single and multiple irregularities, the movement of the cutting edge of the rigidly mounted working body is graphically depicted by sinusoidal curves. The obtained dependencies allow conducting calculations of the automatic system of maintaining the specified slope and establish the area of stable modes of system operation. A geometric method for optimizing the hinge linkage of the working body of trenchless pipelayer is presented.Conclusion. The proposed methods of improving the performance of caterpillar hydraulic reclamation machines with mounted working bodies when moving on uneven ground surfaces can be used to create a wide class of mounted earthmoving machines, both with passive and active working bodies.

The aim of the article is identification of main factors influencing investment attractiveness of land in the cities of Ukraine. To achieve this goal the following tasks: determining trends and key factors in land use of cities; characteristics of land; the definition of urban areas and limitations in their use. Improved classification of the factors which allows for cartographic provision of land in cities and their investment potential, level of interaction between different stakeholder groups, areas of urban development, which allows to generate methodical toolkit for estimation of the level of investment attractiveness of land in cities. Define the factors and features of their influence on investment processes in the sphere of land use of cities of Ukraine. Prospects of further research is to develop a methodological approach to the evaluation of the level of investment attractiveness of land in cities and substantiation of measures on the increase of efficiency of their use.
