Authors: Gierczuk Dariusz , Bujak Zbigniew , Rowiński Jan , Dmitriyev Aleksey 
Published: April 2013

Abstract

Introduction. The aim of the study was to compare CMAs in elite wrestlers and taekwon-do competitors. Material and methods. Forty-nine Greco-Roman wrestlers and ITF taekwon-do competitors were included in the study. The wrestlers were 21.9±2.74 years old, while the taekwon-do competitors were 22.7±5.78 years old. The former group had between 7 and 14 years' training experience and the latter group had from 6 to 16 years' experience. All subjects were elite sportspeople (between first class and international master class levels). Five CMAs were assessed using 14 indices. Computer tests from the Vienna Test System were employed in the study. Results. It was shown that there were no significant differences in CMA levels between wrestlers and taekwon-do competitors. Wrestlers from higher sports classes outperformed competitors who possessed lower sports classes in the majority of CMA indices. Statistically significant differences were observed for simple reaction, movement coupling and high frequency of movements. Taekwon-do competitors at the international master sports class (IM) level scored better than athletes who were at national master class (NM) and first class (I) levels in spatial orientation, reaction time, movement coupling and high frequency of movements. Regardless of the type of combat sport, competitors demonstrated high individual differences in CMAs, which may indicate that a focus on coordination improvement could increase training effectiveness. Conclusions. Further research on identifying predominant CMAs in sportspeople at different levels of competition, particularly in those achieving significant sports successes may be conducted. Tests to thoroughly diagnose coordination should be employed in such investigations.

Authors: Baran Tomasz 
Published: April 2013

Abstract
New records of eleven rare species of Lepidoptera are given from Poland. Stigmella naturnella (KLIMESCH, 1936) (Nepticulidae) has been recorded in Poland for the first time. Surprisingly, this nepticulid was found in an artificial ecosystem - a city park. The occurrence of Scrobipalpula tussilaginis (FREY, 1867) and Ephysteris inustella (ZELLER, 1847) in Poland has been confirmed after over a century. Salix caprea L. is given as the first reliable record of a host plant for the larva of Teleiodes flavimaculella, and Betula pubescens EHRH. is found to be a new host plant of Stigmella naturnella.

Authors: Raina Rifat H. , Saini Malkiat S. , Khan Zakir H. 
Published: April 2013

Abstract
Bombus simillimus SMITH is a west Himalayan species, known only from Pakistan and India. In the Indian Himalaya this species is restricted to Kashmir, Himachal Pradesh and Uttarakhand. So far, it has never been recorded from other regions. Its females (workers) can be recognized by the chocolate brown pubescence of the metasomal terga 1 and 2. The colour pattern of the queen is very distinct, with the whole body coloured black except for the last two metasomal terga, which are brick-red. In Kashmir Himalaya it is widespread around the lower mountain coniferous forest and was found foraging heavily on Trifolium pratense, Lavatera cashmeriana, Carduus spp. and Cirsium spp. Being very common and having a very wide distributional range, it is associated with a sizeable number of host plants. Due emphasis has been laid on its detailed taxonomic descriptions, synonymy, host plants, distribution pattern and illustration. Thirty-five food plants of this species have been recorded from the study areas.

Efficiency of the European Social Fund Contribution to the Regions of Latvia
Authors: Latviete Ilze 
Published: April 2013

Abstract
From 2004 till mid-2007, the economics of Latvia experienced fast development, which to some extent was influenced by accessing the European Union (EU), which in its turn provided access to the EU funds and subsequently to significant investment in the country’s development, thus also affecting the topicalities of social security and employment. Because of the world recession, the EU has experienced an economic downfall which hit Latvia and its regions very hard, causing a significant reduction in the economic activity, increase in the unemployment level, and the risk of social stratification. To facilitate the socio-economic development of the regions, to increase the level of welfare in the regions with lower socio-economic development indicators, as well as to prevent the possibility of appearance of unfavourable situations in the future, it is necessary to use correctly the EU funds available in Latvia, including the financing of the European Social Fund (ESF). In the period from 2004 till 2010, the Riga region has acquired 33% of the total ESF financing in the welfare sector, Latgale has the second largest financing - 25%, but the other resources have been acquired in a more or less equal amounts in the other regions: Kurzeme (16%), Zemgale (14%), and Vidzeme (12%). The ESF financing in the welfare sector has influenced the socio-economic indicators of the regions. Functional correlations are observed among the ESF financing in the welfare sector and the value changes in the number of registered unemployed persons, job seekers and the territory development index.
The Role of Agribusiness in Maintenance of Future Rural Employment in Latvia
Authors: Krievina Agnese , Leimane Ieva , Miglavs Andris 
Published: April 2013

Abstract
Agriculture and manufacture of food products is important source of employment in Latvia. The number of people engaged in agribusiness has considerably decreased over the past years in Latvia. Therefore the paper seeks to analyze the existing situation in utilization of agricultural potential, as well as to evaluate the role of agribusiness potential in maintenance of rural employment in Latvia. The potential is analyzed in the context of the productivity of the persons employed in agribusiness, land use and the self-sufficiency level with the main food products in Latvia. The value added in Latvian agribusiness is very low in comparison with other EU countries, indicating low labour productivity in Latvia. The potential of agricultural land is also not fully utilized in Latvia, which gives basis to consider obtaining of higher agribusiness output in Latvia at the expense of inclusion of additional land resources. The development of the potential of Latvian agribusiness is to be associated with the satisfying of demand for meat in local market and increase in the supply of dairy products on export market. Considering the necessity to reach at least the EU average labour productivity, even the full utilization of agricultural potential is not sufficient for the maintenance of rural employment in Latvia at the level close to current. The decrease in employment in the agribusiness of Latvia cannot be stopped, even more - it is possible that it will continue provoke the decrease also in other sectors of economic activity, namely - sectors of public and private services provided to people in rural space.
Development of Immovable Property Tax in Latvia
Authors: Štucere Sandra , Mazūre Gunita 
Published: April 2013

Abstract
Immovable property tax is one of the national taxes the administration of which is subjected to continuous changes. Frequent amendments to the law “On Immovable Property Tax” (1997) also evidence the mentioned changes. The procedure for tax calculation, tax base, and tax rates has been considerably changed in the course of time. The research provides a discussion on the changes in tax formation, development, and administration in Latvia to understand better the essence of immovable property tax. The research aim was to analyse the development of immovable property tax and the course of reforms for the period of 1998-2012. The research also studies the expected changes in the application of immovable property tax from the year 2013. It is envisaged to transfer the rights to local governments to determine the immovable property tax rates in their administrative territories within the range of 0.2-3% from 2013. The research concludes that frequent reforms of immovable property tax have promoted the development of a new, stable, and predictable methodology for the future application of immovable property tax in Latvia. The analysis of revenues from immovable property tax for the period of 2006-2011 is based on the annually growing significance of immovable property tax. The research suggests that immovable property tax is the only tax the revenues of which have increased within the period of 2009-2011 and the largest revenues from immovable property tax are collected in Riga City municipality comprising 53% of the total revenues from immovable property tax collected in Latvia.

Authors: Darvishi H. , Hadi Khoshtaghaza M. , Najafi G. , Zarein M. 
Published: April 2013

Abstract
The effect of the microwave-convective drying technique on the moisture ratio, drying rate, drying time, effective moisture diffusivity, microwave specific energy consumption, and energy efficiency of sunflower seedswere investigated.Drying took place in the falling rate period. Increasing the microwave power caused a significant decrease in the drying time. The drying data were fitted to four thin-layer drying models. The performance of these models was compared using the coefficient of determination, reduced chi-square and root mean square error between the observed and predicted moisture ratios. The results showed that the Page model was found to satisfactorily describe themicrowave-convective drying curves of sunflower seeds. The effective moisture diffusivity values were estimated from Fick diffusion model and varied from 1.73 10-7 to 4.76 10-7m2s-1. Increasing the microwave power resulted in a considerable increase in drying efficiency and a significant decrease in microwave specific energy consumption. The highest energy efficiency and the lowestmicrowave specific energy consumption were obtained at the microwave power of 300 W.
Biases in methane chamber measurements in peatlands
Authors: Juszczak R. 
Published: April 2013

Abstract
The paper presents results of CH4 emission measurements at peatland with the application of the dynamic chamber technique. The measurements were conducted in two types of chambers differing in shape, height, volume and technology used to assure their tightness. The study tested how the following factors: 1) forced chamber headspace mixing or its absence, 2) mistakes of the person conducting measurements, 3) improper application of linear technique for calculating CH4 fluxes, and 4) simulated air sampling typical for static chambers, influence the significance of errors and the underestimation rate of CH4 fluxes measured in situ. It was indicated that chamber headspace mixing allows estimating methane fluxes with a smaller error than in the case of measurements conducted without mixing, and CH4 fluxes in such conditions can be 47 to 58% higher (depending on the chamber type) than in a chamber without fans. Using dynamic chambers and a fast analyzer to measure methane fluxes allows shortening the methane measurement process to a few minutes. On the other hand, using static chambers for methane flux measurements may lead to 70% underestimation of the calculated flux.
Mechanical properties of some granular agricultural materials used in silo design
Authors: Moya M. , Aguado P.J. , Ayuga F. 
Published: April 2013

Abstract
The aim of this research was to provide values for different material properties considered in either traditional or more recent numerical silo design methods. Different samples of granular agricultural materials commonly stored in silos were tested. Common geotechnical devices have been used in order to make the replications easier. Based on these experiments it was determined that the different material properties were not affected by the test velocity, except in the case of Poisson ratio. From a practical point of view, the test velocity correlates well with the sliding velocity of grain during discharge. The values obtained for material properties considered in traditional silo design methods were similar to those reported by other authors. No significant differences were observed in the results obtained when using either the square shear box or the circular shear cell. The same conclusion was reached when comparing the results from direct shear tests with preconsolidated and unconsolidated samples. This means that simplified devices and procedures can be used in agricultural grains against other products. Finally, a table with the recommended values for the different parameters determined for each sample tested was provided in this work.

Authors: Rampazzo N. , Rampazzo Todorovic G. , Mentler A. , Blum W.E.H. 
Published: April 2013

Abstract
The results showed that glyphosate is initially adsorbed mostly in the upper 2 cm. It is than transported and adsorbed after few days in deeper soil horizons with concomitant increasing content of its metabolite aminomethylphosphonic acid. Moreover, Fe-oxides seem to be a key parameter for glyphosate and aminomethylphosphonic adsorption in soils. This study confirmed previous studies: the analysis showed lower contents of dithionite-soluble and Fe-oxides for the Chernozem, with consequently lower adsorption of glyphosate and aminomethylphosphonic as compared with the Cambisol and the Stagnosol.
Head rice yield response to low and high drying and tempering conditions
Authors: Sadeghi M. , Nasrnia E. , Masoumi A.A. , Hemmat A. 
Published: April 2013

Abstract
The influence of drying and tempering conditions on head rice yield of long- and medium-grain rough rice varieties was investigated. The head rice yield values for the medium-grain variety at high drying conditions and 1.5 and 3% points moisture content removal were even significantly higher than the corresponding values for the long-grain variety at low drying conditions. 1.5% points moisture content removal yielded the least damage to the rough rice. Under low drying conditions, tempering had no meaningful effect on head rice yield for all drying durations. For both varieties, using high drying conditions with 6% points moisture content removal at first drying stage associated with 120 min tempering duration could be suggested as a rapid and energysaving operation to achieve high head rice yield values.

Authors: Soleimani Pour-Damanab A.R. , Jafary A. , Rafiee S. 
Published: April 2013

Abstract
This study presents mathematical modelling of bread moisture loss or drying during baking in a conventional bread baking process. In order to estimate and select the appropriate moisture loss curve equation, 11 different models, semi-theoretical and empirical, were applied to the experimental data and compared according to their correlation coefficients, chi-squared test and root mean square error which were predicted by nonlinear regression analysis. Consequently, of all the drying models, a Page model was selected as the best one, according to the correlation coefficients, chi-squared test, and root mean square error values and its simplicity. Mean absolute estimation error of the proposed model by linear regression analysis for natural and forced convection modes was 2.43, 4.74%, respectively.

Published: April 2013

Abstract
In the paper a method of MST (minimum spanning tree) graph-based image segmentation supported by parallel GPUprocessing has been presented. It has been applied to images of foam matrices filled with mould fungi of Mucor genus. The aim of the segmentation was to extract the profiles of the matrix objects from image background. Parallel computing methods were used to the initial image filtering, graph edge array building and sorting. The results obtained with graphbased method both with and without parallel processing have been compared with conventional analysis in MATLAB environment. It has been verified that GPU processing clearly reduce execution time of the algorithm.

Integration of Digital Images and Laser Scanning Data for the Survey of Architectural Objects
Authors: Mikrut Sławomir 
Published: April 2013

Abstract
The goal of integration is to utilize a spatial model of an object obtained from the cloud of points and, possibly, to support it with a photogrammetric model in those places, where scanner measurements may be hard to perform, or even impossible. Since the image offers a possibility of texturing objects obtained most often from digital metric images, integration makes it possible to create a model of a view resembling the actual one. Another advantage of a photogrammetric model is the possibility of obtaining object edges with high accuracy (due to, among other things, the application of sub-pixel algorithms). It is just that aspect which, in relation to scanning, is described in the paper. The correctness of locating objects, which have been extracted from points, is tested by placing them on a photogrammetric model. In the proposed method, the authors tested extraction of objects, which was based on methods using the first and the second derivatives of a digital image. Those algorithms had been developed and tested earlier in many engineering projects that were based on a multilevel analysis of digital images. Research works were performed on several selected test facilities, located in the open-air ethnographic museum at Tokarnia, Poland.

Authors: Węgliński Tomasz , Fabijańska Anna 
Published: April 2013

Abstract
Paper presents the concept of applying image segmentation algorithms for precise extraction of cerebrospinal fluid (CSF) from CT brain scans. Accurate segmentation of the CSF from the intracranial brain area is crucial for further reliable analysis and quantitative assessment of hydrocephalus. Presented research was aimed at the comparison of effectiveness of three modern segmentation approaches used for this purpose. Specifically, random walk, level set and min-cut/max-flow algorithms were considered. The visual and numerical comparison of the segmentation results leads to conclusion that the most effective algorithm for the considered problem is level set, although the positive medical verification of the results revealed that either of considered algorithms can be successfully applied in the diagnostic applications.

Authors: Chmiel Wojciech , Kwiecień Joanna , Mikrut Zbigniew 
Published: April 2013

Abstract
The design of a methodology for the effective scene understanding systems is one of the main goals of the researchers in the analysis of video surveillance. The objects in the scene have to be identified. Hence, it is necessary to detect the parts belonging to the background. In the article we introduce the base algorithms, which enable us to realization of scenarios. We briefly describe base algorithms (object detection, object localization, recognition of humans, movement detection and configuration of scene) used in three selected scenarios: violation of protected zones, abandoned objects and vandalism (graffiti). These scenarios were tested on several films, obtained from Internet and made by participants of project SIMPOZ. The results of our experiments are presented. The basic algorithms for detecting and locating objects are very quickly, but movement detection ("optical flow") and recognition of humans algorithms work longer.
Real-Time Detection of Movement in Prohibited Direction for Video Surveillance System
Authors: Komorkiewicz Mateusz 
Published: April 2013

Abstract
Video surveillance systems are well established tools for monitoring important areas and detecting abnormal situations. In places such as one way road or tunnel, airport arrival gate, subway entry gate etc. it is important to monitor the direction of movement and to detect those which are prohibited. If the event is detected in the same time when the situation happens, a fast reaction can fix the problem (turning on the red light to prevent cars from entering the tunnel, sending security force to stop and search the suspect etc.). In the article a working system which is able to detect movement in prohibited direction is presented. The algorithm proved a very good detection rate for tested movie sequences. By optimizing various aspects of the algorithm a real-time efficiency (30fps) for 640×480 resolution frames is achieved.
