На основі регресійних моделей побудовано нормативно-інформаційні таблиці для зони Північного Степу України. Практична значущість. Одержані системи нормативів надають можливість оцінювання екологічних та енергетичних ресурсів, а також розрахувати депонування вуглецю у штучних соснових деревостанах досліджуваного регіону. The purpose of the article is to develop the standards for evaluating the trunk components of the aboveground phytomass of pine stands in the Northern Steppe of Ukraine. Methods of research. The method of collecting and processing the research material, developed by Professor P.I. Lakyda, was used in the presented paper. The statistical processing, correlation analysis and the search of regression dependences of phytomass components of the common pine trunk on the taxation indices of the tree stand were made.           The research results. The working data mass has been formed concerning the results of field and laboratory researches, which characterizes the components of the trunk phytomass for assessing biotic productivity of artificial pine stands in the Northern Steppe of Ukraine. Correlation analysis of the relation closeness of the main phytomass components of the tree stands with their basic taxational signs was carried out. A direct close relation of the trunk phytomass components in the bark and wood without bark with the average tree diameter and the height of stands has been established. The value of correlation coefficient of the bark phytomass with all taxational indices, except the density, demonstrates the moderate relation. Mathematical models have been developed and obtained to assess ordinary pine stands’ phytomass by the components of the trunk wood, trunk wood in the bark, and bark of the trunk. It has been determined that the increase of all the studied components of the aboveground trunk phytomass occurred together with increasing the average heights and diameters of tree stands. The elements of scientific novelty. Standard and information tables have constructed on the basis of regression models for the zone of the Northern Steppe of Ukraine. Practical significance. The obtained systems of standards enable to evaluate ecological and power resources and calculate the carbon sequestration in artificial pine tree stands of the studied region.

Structure 1. Reasons are given for believing that the methods used to produce the classical Golgi network cannot be relied upon to give an accurate picture of the structure of the Golgi element during life. 2. In this investigation reliance has been placed chiefly on vital observations and on the results of the formal-sudan-black technique. Sudan black is a colouring agent with an intense affinity for lipoids,1 whether ‘masked’ or not. 3. The Golgi element was studied in the following cells: (1) the primary spermatocyte and early spermatid of the common snail, Helix aspersa; (2) the absorptive cell of the intestinal epithelium of the smooth or common newt, Triturus vulgaris ; (3) the nerve cell of the anterior mesenteric ganglion of the rabbit, Oryctolagus cuniculus. 4. In its fully developed condition, the Golgi element of diverse cells consists of four parts: (1) the ‘neutral-red vacuoles’; (2) the dense lipoid-containing substance, generally in close relation to the vacuoles in the form of strands, ‘lepidosomes’, caps, crescents, rings, or complete investments; (3) the diffuse lipoid-containing substance, which fills all the space in the Golgi element not occupied by the other constituents; (4) the Golgi-product, which arises in the vacuoles and is the result of the synthesis achieved by the Golgi element.

Purpose The purpose of this paper is to investigate the relationship of values with individual economic behaviour, identifies the correlation between personality values that are conditioned upon the culture, and evaluations of economic behaviour situations on the example of Russian culture. Design/methodology/approach This study involved 222 people of Russian nationality, young entrepreneurs employed in the commercial field, developing their own business. The following methods were used in the study: the methodology for measuring the values of an individual and cultural level; Melbourne Decision Making Questionnaire, a scenario methodology for economic behaviour, which is a short behavioural scenario (model of behaviour), taken from real life. The statistical processing of experimental data was carried out using the IBM SPSS Statistics Version 21 software package. Findings The values with correlated progressive and regressive economic forms of behaviour were identified for modern Russian society. The correlation of factors with progressive and regressive economic behaviour was also identified. Practical implications The practical significance of the study lies in the possibility of applying the results obtained not only in the system of economic education but also in programs to support the business activity of young entrepreneurs. Originality/value The value of this study is determined by the fact that it can be placed in a broader context of research into the relationship between the levels of human consciousness and his behaviour.

The aim of the work is to study the possibility of usage the near-miss incidents as the indicators reflecting the level of potential hazard at the workplaces of workers, in particular with stable functional changes in the state of health. This approach is of great preventive value, since it allows obtaining the information about the level of hazard even before it is realized in the form of a certain undesirable event, such as an accident or a casualty. Research methods. The information about near-miss incidents and the potential consequences of hazard realization was obtained using a questionnaire of employees with subsequent statistical processing of the results. Results. Based on the results of studies of near-miss incidents at the workplaces of various groups of workers, it was determined that disability and the severity of disabilities affect the frequency and potential severity of these incidents. In comparison with the control group of workers who did not have stable functional changes in their health, in the process of performing production tasks by workers with II disability group, near-miss incidents occurred 36% more often, and with workers of III group – by 22%. Increase of the potential severity of incidents depending on the group of disability is determined. The scientific novelty lies in the development of ways to use near-miss incidents as indicators of the level of hazard at the workplace of workers with disabilities. The practical significance lies in obtaining information about the frequency and possible severity of near-miss incidents at the workplaces of workers using the example of a metalworking workshop at the enterprise in Kharkiv. The introduction of the procedure to collect information about near-miss incidents with subsequent data processing allows forming data for making managerial decisions to improve the OSH management system at the enterprise and develop effective measures to prevent industrial injuries.

Through an analysis of Gregory of Nyssa's treatise On the Soul and the Resurrection, this article argues for the compatibility of the doctrines of the immortality of the soul and the resurrection of the body. Nyssa's view is explicitly contrasted to contemporary tendencies to set up a false dichotomy between the two doctrines. After answering the common objection that immortality is an intruder to Christian theology, a typology of four views on the relation between immortality and resurrection is set out. The article concludes with reflections on the theological and practical significance of Gregory's view.

AbstractKnowledge of the effects of variables that can influence trapping results should help to optimise efforts in exotic species detection and other surveys. Two vertical trap placements (understorey, canopy) were tested to determine influence of these two heights on captures of Scolytinae (Coleoptera: Curculionidae), Cerambycidae (Coleoptera), and Siricidae (Hymenoptera) using semiochemical-baited multiple-funnel traps. Traps were baited with α-pinene, ethanol, ipsdienol, and ipsenol. A total of 8463 insects from 65 species and one genus were captured during the study. Average species richness, species diversity, abundance, number of unique species, and expected diversity were higher in understorey compared with canopy traps. Jaccard (0.94 ± 0.05) and Sørensen abundance (0.97 ± 0.03) similarity indices suggested highly similar communities sampled at the two trap heights. Dendroctonus valens LeConte, Dryocoetes autographus Ratzeburg, Hylastes opacus Erichson, Orthotomicus caelatus (Eichhoff), Gnathotrichus materiarius (Fitch), Asemum striatum (Linnaeus), Monochamus scutellatus scutellatus (Say), Rhagium inquisitor (Linnaeus), and Xylotrechus sagitattus sagitattus (Germar) were more abundant in understorey traps. In contrast, Ips pini (Say), Pityogenes hopkinsi Swaine, Monochamus carolinensis (Olivier), Acmaeops proteus (Kirby), and Astylopsis sexgutatta (Say) were more abundant in canopy traps. The common practice of trapping in the understorey may be optimal for sampling arboreal insects as part of survey efforts. However, additional species may be found by trapping at other vertical placements.

Two methods of fitting the allometric weight–length relationship are described, one involving the common logarithmic transformation of variables in a multiplicative model and the other assuming an additive nonlinear model and general nonlinear estimation procedures. Differences in the assumptions involved in the two methods are emphasized and the practical significance of the different methods is demonstrated with the aid of a sample problem. A number of procedures are suggested to compensate for possibly unjustified assumptions.

Employment policy has won primary attention both at national and EU levels for the past decade. Managing its problems has become one of the major social economic and political challenges. One of the problems is the aging of the continent’s population, which is in close relation with the slow increasing or decreasing economic trends.Comparing the EU’s unemployment, employment and labour productivity rates to those of ten years earlier a positive tendency can be traced. On of the other hand compared with the USA, Japan or the average of OECD countries the Community has still not been able to reduce its several decades lasting leeway. Difficulties of labour management are much more striking in rural territories than in urban districts. Not even the second pillar of the Common Agricultural Policy: the rural development has been successful in managing the employment of the labour supersededfrom the primer sector so far, which is significantly reflected in the unfavourable indicators of labour management and unemployment.
