Extending the duration of economic use of cows and enhance their productivity was and is now an important component of genetic improvement in many countries. The duration and effectiveness of lifetime usage of animals closely related not only to economic efficiency, but also to the selection process, since for both the production and breeding the most valuable animals are those who have these two combined successfully features. Therefore, the aim of our research was to study the effect of different linear affiliation of Holstein cows on the duration and effectiveness of their lifetime productivity, identify the best variants of interline and intrinsically linear selection of parental pairs. Studies conducted on the materials of primary breeding accounting in herds in Vinnytsia, Rivne, Cherkasy, Kirovohrad and Kyiv regions. Retrospective analysis of life expectancy and efficiency of the use of cows was performed by Yu. P. Polupana method. (2010). The analysis involved information about economic use and lifetime productivity of 2902 cows, while all animals were taken into account, first calving of which was in 1996-2008 and who left the herd after finishing the first lactation with duration at least a minimum of 240 days. It was found that in terms of duration and effectiveness of productive use indices of daughters from different bulls were different. By the life duration, productive use, number of lactations in life and the best lifetime performance were the daughters of bull Rok 373840409, and worse – Dzhokus 113080315. Rok 373840409, Lord 661287, E. Samb 3035115974, Bg. Rodeo 27642626161 and V. Astronomer 2160431 turned to be improvers by these features. The best by duration of economic usage and by lifetime productivity were animals of Treyt lines 1629391, Valiant 1650414 and Eleveysh 1491007 and cows whose mothers belonged to line R. Sayteyshn 267150 and R. Sovrin 198998. Worse than the aforementioned indices were cows of J. Besn line 5694028588 and animals whose mothers came from a line of Adem 26781. Identify the best variants to combine parental pairs with interline and intrinsically linear selection may contribute to lengthening the duration of productive use of cows and increase their lifetime productivity. Analysis of interline selection of animals showed that the most successful combination was when cows belonged to Bell lines, and bulls – to Eleveyshn line. Animals from this combination had the longest used in the herd (4,43 lactations) and they had the highest lifetime productivity (38671 kg of milk). The second position by studied parameters got cows from the combination of Starbuck-Eleveyshn (3,77 lactations and 28150 kg of milk). Long term usage and high lifetime productivity is well combined by animal from the cross of Eleveyshn-Bell lines (3,53 lactations and 22906 kg of milk). In addition, animals from cross of Valiant-Bell lines characterized by higher figures of usage duration and animals from the cross of Starbuck-Bell lines, Starbuck-Chif and Valiant-Bell had high lifetime yield. The most unsuccessful were all combinations when the mother belonged to line of Adem. Animals from these crosses were used in herds in less than 2 lactations, and their lifetime yield was 11584-13341 kg. By intrinsically linear selection in terms of duration and effectiveness of lifetime usage animals from Eleveyshn line were the best. The duration of use of these animals was 3 lactations and their lifetime yield – 24176 kg. The highest degree of impact on the studied parameters of duration and effectiveness of lifetime usage had animals with origin by the father – 51,6-55,2 %. The impact of the father line, depending on the index, was within 16,7-18,0 %, the mother line – 10,3-11,4 %.

Whilst sustainable construction relates to both a building’s structure and the use of proper life cycle processes, the selection of the most appropriate material/s is deemed a considerable undertaking. Throughout a building’s lifecycle that extends from design, construction, operation, maintenance, renovation, until demolition, the selection of sustainable material/s is a particularly crucial task for the development and establishment of such structures. Traditionally, there are three main materials for general construction: (1) Steel, (2) Concrete and (3) Timber. These materials not only influence the function within the structure, but also affect the operation cost and energy usage. Operation cost reduction and energy savings are typically elements of the sustainable construction sphere. However, in developing countries, there is a variety of highly critical factors, which can impact material selection as well as the long-term sustainability of the structure, including: Fire Performance, Environmental Impact, Structural Performance (strength and durability), and Functioning Capabilities. Accordingly, this paper will first compare the sustainability of these three key materials and then converse with appropriate processes for material selection. Attention will be given to the sustainable construction recompense associated with the different material selection factors. Doing so ensures a more sustainable built environment by means of an improved material selection process.

In order to understand the long-term growth variation of Chinese fir’s geographical provenances and promote long-term genetic improvement, the experimental provenance forest of Chinese fir planted in 1981 was taken as a research object.The provenances originated from southeastern China. The study measured each diameter at breast height (DBH) and tree height at 5, 6, 8, 12, and 33 years of age and analyzed the genetic variation of major growth traits of trees withdifferent provenances at different forest ages. Additionally, the study analyzed the geographical variation of Chinese fir by using the trend surface and principal component analysis (PCA) and evaluated the long-term selection effect of provenance by using juvenile–mature correlation and cluster analysis. The heritability of the DBH, treeheight, and volume of Chinese fir with different provenances reached 0.35–0.76, and with increasing forest age, the heritability of each trait showed a rising and gradually stabilizing trend. There were obvious differences in geographical variation patterns among the tested provenances, and both the DBH and the tree height growth patterns are two-way gradients. This variation pattern is associated with climatic conditions in different regions, and the factors limiting the growth difference of Chinese fir may be the mean temperature in winter and the precipitation in autumn and winter.An early selection age has a significant effect on shortening the timber production cycle of Chinese fir. The selection of trees aged between 6 and 12 years is more conducive to improving the efficiency of the genetic improvement of Chinese fir.The 42 excellent provenances selected from the 33-year-old mature Chinese fir forests have a larger increase in growth than trees with local provenances, which are concentrated in the Wuyi and Xuefeng mountains and are suitable for plantation in the Guangxi Zhuang Autonomous Region and surrounding areas.

Background Despite its role as an effective intervention to improve the long-term health of patients with cardiovascular disease and existence of national guidelines on timeliness, many health services still fail to offer cardiac rehabilitation in a timely manner after referral. The impact of this failure on patient health and the additional burden on healthcare providers in an English setting is quantified in this article. Methods Two logistic regressions are conducted, using the British Heart Foundation National Audit of Cardiac Rehabilitation dataset, to estimate the impact of delayed cardiac rehabilitation initiation on the level of uptake and completion. The results of these regressions are applied to a decision model to estimate the long-term implications of these factors on patient health and National Health Service expenditure. Results We demonstrate that the failure of 43.6% of patients in England to start cardiac rehabilitation within the recommended timeframe results in a 15.3% reduction in uptake, and 7.4% in completion. These combine to cause an average lifetime loss of 0.08 years of life expectancy per person. Scaled up to an annual cohort this implies 10,753 patients not taking up cardiac rehabilitation due to the delay, equating to a loss of 3936 years of life expectancy. We estimate that an additional £12.3 million of National Health Service funding could be invested to alleviate the current delay. Conclusions The current delay in many patients starting cardiac rehabilitation is causing quantifiable and avoidable harm to their long-term health; policy and research must now look at both supply and demand solutions in tackling this issue.

SummaryThe objective of the present study was to describe the frequency of the main racial traits of Morada Nova sheep and simulate the impact of this culling on the response to selection for birth weight. The data from sex, coat colour, hoof pigmentation, muzzle pigmentation, polled and cryptorchidism were collected individually at weaning from 385 Morada Nova sheep of the red variety, born between 2010 and 2012, which belonged to four different flocks in the state of Ceará, Brazil. To estimate the impact of culling of animals due to racial pattern on the genetic improvement of the Morada Nova population, the genetic gains in birth weight per generation were calculated considering the following different scenarios of culling due to racial pattern in a simulated population. The present results indicate that the most urgent step is flexibilization of the requirement of dark muzzles and hooves. The selection of Morada Nova sheep based on racial pattern has caused losses in the genetic gain for productive traits such as birth weight. Readaptation of the official racial pattern established for Morada Nova sheep is necessary so that the racial pattern is achieved and an adequate number of animals will be available for selection.

Managers who are responsible for the management of companies are faced with two important decisions - investment and funding. The right investment decisions and choice of funding sources are important because they affect the company's financial performance. The selection of the types of assets to be invested and the right types of financing sources result in optimal returns for the company. It reflects good company performance and future prospects. In addition, optimal return is a good sign for investors. Companies that perform well experience increase in the value of their firm. This study examined the effect of investment decisions and the selection of appropriate sources of funds on the performance of the company and the consequent impact on the firm value. The study was conducted in two parts. The first part examined the effect of investment decisions on long-term assets with long-term funding on the rate of return and firm value. The second part examined the effect of investment decisions on the company's short-term assets and funding for financial performance and firm value. The case study used in this research is a consumer goods sub-sector company listed on the Indonesia Stock Exchange in the period 2010 to 2017. Path analysis is the data analysis tools that was used. The results of data analysis showed that the asset structure has an effect on financial performance and firm value. The capital structure affects the financial performance but does not affect the firm value of the company. Financial performance was measured by ROI.

AbstractIn recent years, the use of single-tube skeletons for the construction of Chinese solar greenhouses has increased. As a consequence, during the selection of the construction materials, the safety of these structures has become an important issue. The single tube section has various forms, but there is no scientific theory to guide the selection process. To the best of our knowledge, the scientific analysis of the impact of single pipe cross section on the safety of greenhouse skeleton has not been addressed so far. In this context, the finite element analysis software was used to calculate and analyze the stress elements, displacement of round tube, Ω tube, elliptic tube and square tube under the same load conditions. We used the Chinese Standard values as a reference and analyzed structural features of different sizes and thicknesses of the greenhouse steel skeleton sections under non-uniform snow load. The results showed that, under the same load condition, the maximum stress in the four skeleton materials was all located at the connection of the transverse tension bar and the front roof. In addition, under same load condition, the greenhouse skeleton with elliptic tube presented the smallest cross-sectional displacement between the different materials tested. The effect of increasing the size of the greenhouse frame was better than that of increasing the greenhouse material thickness. All this work will provide theoretical guidance to the material selection of this structure.

The article is devoted to the study of advertising transformation under the influence of new trends of consumption as a social action. It is highlighted that the current socio-economic situation is creating new subjects for the analysis of already well-known objects. The place and role of advertising in modern society is certainly based on its market principles in the past, but today it is necessary to take into account a set of influencing factors that were previously mutually exclusive but are now indivisible. The greatest influence is exerted by the socio-cultural aspect of consumer behavior, which is based on values and motivators that come from the lifestyle in a qualitatively new external environment. It means that they are not limited to market transactions. Moreover, in today's conditions, social stratification has receded into the background and is not among the main factors of influence. This transformation of understanding the practice of consumption allows to reasonably recruit and use advertising tools to increase their effectiveness. It is determined that during forming an advertising campaign it is necessary to consider the impact on consumer behavior of modern information technology, namely the selection of the necessary information from the large amount that is available. A large amount of information creates an ambiguous situation for the consumer. This requires the integration of advertising tools. It is established that the parallel use of several advertising media allows to carry out the influence similarly to the technology of purposeful management. The availability of technical means that quickly realize the desire can be recommended for both long-term brand communication and for the short term.

The aim of research was to study the duration the effectiveness and lifelong use of Ukrainian Black-Spotted dairy breed cows and the impact on these indicators of milk yield for the first and best of lactation. Research was carried out in Ltd. «Milk River» Sokal district, Lviv region. It is established, that the highly indices of life expectancy, productive use, lactation, number of lactations for life and the coefficient of economic use there were cows, milk yield for the first lactation of which was 3501–4000, for the best – 5001–5500 kg, but for the lifelong yields and the amount of milk fat – with the milk yield for the first lactation 4001–4500,  for better – more than 6000 kg. Better by yields and the number of butterfat on one day of life, productive use and lactation were cows with milk yield for the first lactation of over 5500 kg, and for better – more than 6000 kg. Thanks to the correlation analysis is set different levels and the direction of indicators duration communication and the efficiency and lifetime use of experimental cows with their milk yield for the first lactation. The highest positive and significant correlation coefficients have been established between the animals yields for the first lactation and their yields (0.426–0.812) and the amount of milk  fat  (0.445–0.811) for a day of life, productive use and lactation. Negative, but probable links were between milk yield of cows for the first lactation and the duration of their life, productive use, lactation, number of lactations in life, the coefficient economic use. The greatest influence of cows yield for the first lactation had their yield and the amount of milk fat for a day of productive use (61.89 and 62.47% respectively) and lactation (54.97 and 56.44%) and the lowest – in a lifelong yield (2.01%) and the lifelong number of milk fat (1.97%). The largest predicted value had the links between the yields for the best lactation of cows and their lifelong milk yield, lifelong number of milk fat, yields and the amount of milk fat for a day of life and productive use and lactation. These links in all cases were close, highly reliable and were in the range 0.598–0.911. The lowest correlation coefficient, in addition improbable and negative, was observed between milk yield of cows for the best lactation and average fat content in milk for all lactation (-0.008). Significant influence of better lactation on the above mentioned indicators are confirmed by our calculation the indicators of influence power, which ranged from 39.53 to 77.68%. The lowest power of influence of this factor was observed in the average fat content in milk for all investigated lactation (1.02%).
