The aim of the study was to evaluate the effect of grass pasture on the performance of slowly growing chickens. Both sexes (72 chickens) of the slowly growing hybrid Hubbard JA 757 were used in the experiment, which was carried out in the summer 2015. The chickens were divided into two groups with six replications. After 34 days of age, half of the chickens were transferred to outdoor fields to the transferable cages (EXP). The second half of chickens stayed in the house in a controlled microclimate condition. The live weight of chickens at 63 days of age was 2.93 kg in the EXP and 3.14 kg in the CON, and there was no significant difference between...

Electroless deposit Ni-P/SiO2 composite coating was performed on the steel substrate, DIN EN 10130. The preparation of nickel coating included two main steps. In the first step, the fraction of SiO2 particles sized the tens of nanometres was obtained by sedimentation. In the second step, the composite coating was plated on the steel substrate. The actual deposition process contains the deposition of plain Ni-P interlayer which served as the nucleation center for the deposition of Ni-P/SiO2 composite coating with co-deposited SiO2 particles. The morphology of deposited composite coating was studied by scanning...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2016, 64(5), 1483-1494 | DOI: 10.11118/actaun201664051483
For a design of the volume of the rainfall infiltration facility, the coefficient of infiltration is determined by an infiltration test. The use of the coefficient of infiltration brings certain uncertainties into the solution, arising from different conditions in carrying out the infiltration test and in operating a real infiltration facility. In this study an analysis is carried out of factors that influence the process of infiltration and related uncertainties influencing the determination of the storage volume of the infiltration facility. The effect of the individual factors on the design of the infiltration facility was analyzed using numerical...

The aim of the paper is to determine the effect of water erosion on maximum capillary water capacity, bulk density, soil airiness, total porosity and minimal air capacity. For this purpose, 13 plots located in South Moravia were selected. Each plot was divided into three positions. The first one, eluvial, was located on the top of the slope. These were always flat and water erosion did not occur there. The second one was midslope position where soil was damaged by water erosion. Soil washed down from the midslope position was accumulated in the third one. It has been found that water erosion has a statistically significant effect on minimal air capacity...

Rising popularity of geocaching is linked to increased risk of negative impacts on natural environment. Based on that, this paper intends to present possible approach of how to evaluate these impacts in the Landscape protected area Moravian Karst (Czech Republic) and in the Vrátna dolina valley (National park Malá Fatra, Slovak Republic). Recreation along with nature conservation has been solved in these areas in the log-run and geocaching has been steadily extending offer of recreational activities. Therefore, it seems desirable to examine how geocaching affects environment and simultaneously how topography or land cover influences availability or...

While there has been voluminous research on the determinants of FDI for developed and developing countries, little has been done on this issue for transition economies, especially, for the Commonwealth of Independent States (CIS) countries. the present paper examines the determinants of inward Foreign Direct Investment (FDI) flows in the CIS during 1995-2010. the results of empirical analysis using panel data models, conducted with the purpose of identifying the factors that determine the motivation and decision of multinational companies (MNC) to invest in CIS economies, show that regardless of the presence of high investment risk in transition economies,...

Globalization is a broad concept casually used to describe a variety of phenomena of countries. However, there is no universally accepted definition and neither standard measurement for globalization nor social dimension of globalization. Many attempts have been made to measure globalization. Authors introduce single indices - economic and social globalization index and index for progress in reducing income inequality as fuzzy membership functions. Authors analyse the dependence of the new indices. Authors create clusters of similar EU countries in the view of these two indices with the help of fuzzy c-cluster analysis. The result is two clusters of...

It was found that more Austrian and German SMEs, compared to Czech, Slovak and...

This paper deals with an anonymous data collection in the Internet of Things (IoT). the privacy and anonymity of the data source is important for many IoT applications, such as in agriculture, health, and automotive. the proposed data-collection system provides anonymity for the data sources by applying a cooperation group scheme. the group scheme also provides a low power consumption. the system is built upon the Tor (The Onion Router) anonymous network, which is a part of the Internet darknet. the proposed system was designed for the Android devices on the client side and for Java environment on the server side. We evaluated the anonymous data collection...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2016, 64(5), 1805-1821 | DOI: 10.11118/actaun201664051805
The persistent slump in crude oil prices on the world market has drastically reduced government revenues, weakened currencies, and threatened growth and development of countries such as Nigeria that are heavily dependent on petroleum as a source of government earnings. Therefore, it has become imperative for the government to look beyond oil, notably agriculture to survive the present shocks. Given that agriculture is the largest non-oil export in Nigeria, this paper assesses the general performance of agriculture in the country. The article also verifies the relationship between trade, external financial flows and agricultural performance in the country,...
