: The subject of this paper is the research of the influence of different ratios of buckwheat, in concentrated feed, on the qualitative values of laying hen eggs. The study was conducted in four groups of laying hens: one control and three experimental, which were formed with respect to different proportions of buckwheat in meals. Within the first group of laying hens, a concentrated feed mixture with 10% relative share of buckwheat was used, within the second group with 20% relative share of buckwheat and within the third group with 30% relative share of buckwheat, while in the control group standard concentrated food was used. Based on the conducted research, it can be concluded that buckwheat in the meal of laying hens has positive effects on quality, physical properties, sensory properties and frequency of carrying. It was shown that there are statistically significant differences in mean values for the following variables: protein content in egg white, protein content in egg yolk (%), fat content in egg yolk (%), where the highest value was recorded in the third group of laying hens. Also, statistically significant differences were found in terms of shell weight (g), shell thickness (mm), yolk diameter (mm) and egg white pH. The highest average frequency of egg laying was found in the first group and the lowest average frequency of egg laying was in the control group. The general conclusion is that buckwheat can be used in poultry feed, because it has a much greater positive than negative effect on the production and quality characteristics of eggs for consumption.

. Agricultural headwater streams are important pathways for diffuse sediment and nutrient losses, requiring mitigation strategies beyond in-field measures to intercept the transport of pollutants to downstream freshwater resources. As such, floodplains can be constructed along existing agricultural streams and ditches to improve fluvial stability and promote deposition of sediments and particulate phosphorus. In this study, we evaluated 10 remediated agricultural streams in Sweden 15 for their capacity to reduce sediment and particulate phosphorus export and investigated the interplay between fluvial processes and phosphorus dynamics. Remediated streams with different floodplain designs (either on one side or both sides of channel, with different width and elevation) were paired with upstream trapezoidal channels as controls. We used sedimentation plates to determine seasonal patterns in sediment deposition on channel beds and floodplains and monthly water quality monitoring. This was combined with continuous flow discharge measurements to examine suspended sediment and particulate phosphorus 20 dynamics and reduction along reaches. Remediated streams with floodplains on both sides of the channel reduced particulate phosphorus concentrations and loads (-54 μg L -1 , -0.21 kg ha -1 yr -1 ) along reaches, whereas increases occurred along streams with one-sided floodplains (27 μg L -1 , 0.09 kg ha -1 yr -1 ) and control streams (46.6 μg L -1 ). Sediment deposition in remediated streams was five times higher on channel beds compared to floodplains and there was no evident lateral distribution of sediments from channel to floodplains. There was no effect from sediment deposition on particulate phosphorus reduction, 25 suggesting that bank stabilization was the key determinant for phosphorus mitigation in remediated streams

Further, the overall narrow floodplain

• Based on the previous study of the heat-treated wood at 0-3 mm surface layer, this study focuses on the transition of thermal modification intensity on 160-220 °C heat-treated poplar from surface to core layers. The color change was evaluated by CIELAB, and surface hardness was detected via Shore D (HD) and pressing ball method (H R ); furthermore, the FT-IR was applied to detect the thermal degradation of wood components. The results show that the degradation of cell wall components in the surface layer of heat-treated poplar wood is greater than that in the core layers

: Ultrasonic flowmeter works on the principle of transmitting and returning ultrasonic waves that pass through the liquid, ie. fluid, and is used to measure the speed of fluid movement through a pipeline or some other structural form of fluid movement. By knowing the velocity of the fluid and the cross-sectional area of the pipeline or other system, the value of the volumetric or mass flow can be obtained indirectly. Fluid flow measuring device model OMNI TDI 200H owned by the laboratory of the Biotechnical Faculty was used for the first time to measure the flow of purified water at the outlet of the plant device of the training center "Grmeč", built as a pilot plant. The paper will describe the role and importance of flow measurement by the conventional method and present the results of the trial operation of an ultrasonic flow meter, model OMNI TDI 200H.

Legionella bacteria are microorganisms found in water and moist soil. They are especially favoured by moisture and heat, especially in different types of swimming pools where these bacteria reproduce and survive even for several months. Legionella spp. cause human diseases if they are introduced into the body through the respiratory tract. This most often happens by inhalation of aerosols, and less often by microaspiration of water contaminated with Legionella . The research aims to examine the presence of Legionella spp. bacteria in pool waters and the factors that influence their maintenance in these waters. Water samples were taken from 13 swimming pools that were registered for swimming and recreation in the Central Bosnian Canton in 2022. The presence of legionella was tested, and temperature, pH values (method BAS EN ISO 10523:2013), and residual chlorine concentrations were measured. The temperature was measured by immersing the probe with a calibrated thermometer until the stabilization of temperature values on the display was reached. The free residual chlorine was measured by the standard colourimetric technique – the N, N-diethyl-phenylenediamine method (HANNA Instruments 96701, Rhode Island, USA). Descriptive statistics and the Chi-square test will be used for data analysis. Statistical analysis of the obtained data will be performed using the basic functions of MS Excel and GraphPad Prism. Of the total number of analyzed samples (n = 13), the presence of legionella was confrmed in 4 samples (31 %). The average water temperature of the samples taken

A 2-year study was done to compare fruit morphological and chemical composition of three nectarine cultivars grown in south Hercegovinia conditions. A high variability among and within cultivars was found and significant differences were observed among them in all properties analyzed. On the basis of evaluated data, the best fruit performance was registered in ‘Caldesi 2000’ and ‘Venus’ grown in the condition of this part of the Mediteran. This evaluation may help to select a set of nectarine cultivars with better fruit quality attributes, which in our growing conditions might be indicated in ‘Caldesi 2000’ and somewhat in ‘Venus’. The highest average of fruit width (61.18 mm) and fruit weight (148.24 g) was found in cultivar Caldesi 2000. As for friut thickness, also cultivar Caldesi 2000 had the highest value (55.39 mm). The results for the highest fruit length (60.48 mm) had Venus cultivar also fruit stone weight length, width and thickness. The contents sugars (glucose, fructose) total soluble dry matter, and total acids in fruits were found in cultivar Venus, but pH and sucrose were found in cultivar Sun Grand.

The presence of cortical lesions in multiple sclerosis patients has emerged as an important biomarker of the disease. They appear in the earliest stages of the illness and have been shown to correlate with the severity of clinical symptoms. However, cortical lesions are hardly visible in conventional magnetic resonance imaging (MRI) at 3T

Parallel programming is a form of computation in which the calculations are carried out simultaneously, operating on the principle where large problems can be divided into smaller, which are then solved in parallel. Most common this programming is used in high performance computing, but due to the physical constraints which prevent frequency scaling the interest is even higher. As computers consumption has become a problem in the recent years, the parallel programming has grown into the dominant paradigm in computer architecture, mainly in the form of multicore processors. The paper shows the process of designing parallel programs and it includes some results obtained by testing the parallel programming performance of different nVIDIA GeForce graphics cards. The purpose of the test is to compare performance of several types of GPUs for various applications. The results of the test could not specifically say which GPU is best due to the different features of the cards, but they can be used to determine which card offers better performances for different parts of the tests.
