Abstract Subject and purpose of work: The objectives of the elaboration are the following: 1) to analyze the regional changes (at the level of poviats) in the number of farms involved in milk production over the period 2002-2010; 2) to present the main factors affecting the ongoing changes in Polish farms oriented at milk production; 3) to determine the impact of the measure 121. “Modernization of agricultural holdings” under the RDP 2007-2013 and the applied system of direct subsidies for the development of farms oriented at milk production. Materials and methods: The work has been prepared on the basis of the analysis and synthesis of the source literature, statistical data collected and the author’s own reflections. Results: In Poland, in the years 2002-2010 there was a distinct regional differentiation in the pace of the ongoing changes in the dairy sector. The regions, where we observe the development of milk production, include almost the entire Podlaskie Province, the northern part of the Mazowieckie Province and the south-eastern part of the Warmińsko-Mazurskie Province. Conclusions: Within the RDP 2007-2013, significant funds were allocated to support the modernization of agricultural farms. Mainly under the measure 121 “Modernization of agricultural holdings” the investments were carried out in relation to the purchase of mobile equipment, they represented 89% of all investments. This was partly due to the actual demand and administrative procedures that stimulated these types of investments.

Sensitivity plays an important role in the analysis and synthesis of technical systems no matter what complexity or purpose, that is in assessing their accuracy, determining and selecting tolerances for their parameters, or in any optimization process. One of the most important objectives of the information and ballistic launch support, along with the provision of launch data, is to increase the efficiency of aircraft in performing their missions. Therefore, it is of high relevance to assess the function of sensitivity and the function of influence of the information and ballistic launch support on the effectiveness of the functional performance of aircraft formations and ensure, at acceptable costs, the fullest use of their structural and ballistic capabilities. In this paper, we defined and evaluated functions of sensitivity and functions of influence of the main factors of information and ballistic launch support of aircraft launches on their functional performance as a formation. The degree of influence of information and ballistic support factors on the realizability of missions by aircraft formations is represented by numerical indicators. An integral indicator for assessing the impact of information and ballistic support factors on the performance indicators of aircraft formations has been formed as a weighted convolution of increments of partial indicators.

Effect Of Age

A proportional hazard model was used to analyze the impact of the most important factors on the length of productive life in 44 796 Slovak Pinzgau cows. The calculations were carried out with Survival Kit 3.12. The milk production level within a herd was the most important factor. The relation between the milk production level and the culling risk was strongly non-linear. Cows with extremely low milk production (less than 1.5 standard deviations below average) had a 4.8 times higher culling risk than average cows. The culling risk for the highest yielding cows was about one half of the risk of average cows. In the first lactation the culling risk was highest at the beginning and decreased in the course of lactation whereas in subsequent lactations the culling risk was highest at the end of lactation. The risk decreased with parity. The effect of age at first calving did not have a large influence on the length of productive life, although a linear increase in culling risk was observed as the age at first calving increased. Cows from expanding herds were at lower risk to be culled compared to cows in herds of stable and decreasing size.

Blood flow has been extensively studied because of its close relationship with cardiovascular disease. Heart valves blood flow analysis is particularly complex due to the high mobility of its leaflets, a fact that has stimulated the development of computational models aimed to its better understanding. For studying heart valves blood flow, we developed a mathematical model derived from clinical observations based on echocardiographic images, which describe valve leaflets motion and its influence on blood flow. This work presents a concentrated-parameters-based model of heart valves blood flow that takes into consideration five main factors affecting such a flow in the mitral and aortic valves. This model considers factors that are related to blood fluid and valve leaflets characteristics. Considering the main factors involved, it was found that blood flow exhibit an abnormal behavior in response to small variations (less than 10%) in blood pressure gradient or in leaflets stiffness. Likewise, after changing the roughness of the leaflets, the impact is smaller, only slightly affecting blood flow behavior with changes beyond 30%. Moreover, it was observed that the influence of fluid vortices originated behind the valves can be disregarded and the kinetic energy induced by them is almost negligible.

Routine health checkup is the simplest and most scientific method for early detection, minimizing harm, and preventing complications of diseases. However, until now, only a fraction of the population is aware of its importance. Studies in the world and in Vietnam show that the proportion of the population having routine health checkups remains modest. Understanding which factors affect the decision to have routine health checkups is important in creating a system and environment that encourage people to have regular health checkups. The study is based on the survey data of 420 people in Khanh Hoa province to identify the main factors affecting their decision of routine health checkups, using the Logit regression model. The results shows that factors affecting decisions on routine health checkups include: education level, occupation, income, age, chronic illness, waiting time, and the impact of cost. The study also determines that gender and marital status have no effect on regular health checkups. The results highlight the importance of taking into consideration the priorities of time and cost when developing policies to encourage regular health checkups in the population.

Regional development of Russian regions is characterized by a high level of heterogeneity. Researchers highlight a significant number of factors affecting the level of regional development. Geographical factor is recognized as one of the most important factors. The development of border regions is similar to that of Russian regions. The purpose of the research is to determine the differentiation of border regions and to study the dynamics of its change. The object of the research is border regions united in the system. The process of unification of regions is based on geographical location. The subject of the study is the process of regional differentiation. Methods of assessing the convergence of economic entities are the instrument of researching regional differentiation of border regions. The convergence theorem analyzes the interregional differentiation of border regions and considers the possibility of their convergence. As a result of using convergence approaches based on the definition of convergent processes, the coefficient of variation is calculated. On the basis of the calculated values of the coefficient and its change, the possibility of convergence of border regions is assessed and the process of change of interregional differentiation is analyzed. Another direction, on the basis of which the analysis of regional heterogeneity of border regions is based, is the determination of the differentiation coefficient, which allows to determine the level of the gap between polar groups of regions. The goal set in the study will allow assessing the impact of geographical location on economic development and formulating directions of economic policy. Spatial heterogeneity of border regions defined by means of mathematical tools can be used when writing the Program and the Strategy for Regional Development, within which one of the competitive advantages will be the location of the territory.

The vehicle color is considered to be a significant factor affecting driver visibility. The primary objective of this study is therefore to determine the impact of black-and-white striped vehicles (BWVs) on driver visibility through simulation-based experiments. In these experiments, subjects were asked to perform front and rear target identification tasks under daylight and twilight conditions. Then, a 2 (lighting conditions) × 2 (vehicle size) × 5 (vehicle color) analysis of variance was conducted for each task. Under the front identification scenario, the main factors affecting visibility were found to be lighting conditions, vehicle size, vehicle color, and the interactions between these factors. Under the rear identification scenario, lighting conditions and vehicle color were found to be the main factors. The results of this study demonstrate that driver visibility of BWVs is poorer than that of other colors of vehicles and that BWV visibility is susceptible to lighting conditions.

Structural Shifts

The article analyzes the dynamics and provides a forecast for 2021 of the yield of grain and leguminous crops in Russia. According to the results of the analysis for the period from 2006 to 2019, the average annual increase in yield by 0.6 center per ha was revealed for all categories of farms. The average grain yield in the forecast year will be in the range of 26.5 to 29.6 center per ha. The main focus of this article is on the assessment of the impact of structural shifts in sown areas on the yield of cereals and legumes. According to the results of the index method, it was found that due to changes in the regional structure of grain crops, the yield in Russia as a whole increased by an average of 5%. Based on the constructed regression model, it is concluded that the main factors affecting the grain yield are the productivity of the climate and the number of mineral fertilizers applied.

The Impact

The objective of the present review was to establish levels of conserved fodder wastage when feeding livestock (sheep, beef cattle, dairy cattle) under various conditions and using various feed-out systems, and to determine the factors affecting wastage. The mean wastage of hay recorded in the literature reviewed was 17% of the DM offered, but the range was from 4 to 77%. The main factors affecting the degree of wastage were storage method, packaging method, method of feeding out, amount of fodder on offer and its palatability and/or quality and the impact of wet weather. Although the emphasis was on hay, the principles should also apply to silage. If wastage was 40% rather than 5%, the cost of feeding conserved fodder to livestock would be a third greater than producers might expect or budget on.
