Flywheel energy storage control system with the system operating status control via the Internet
Authors: Baszyński Marcin , Siostrzonek Tomasz 
Published: September 2014

Abstract
Modern electronics systems consist of not only with the power electronics converters, but also with the friendly user interface which allow you to read the operating parameters and change them. The simplest solution of the user interface is to use alphanumeric display which displays information about the state of the converter. With a few additional buttons you can change the settings. This solution is simple, inexpensive but allows only local control (within walking distance from the system) and the number of displayed information is low. You can create extensive menu, but it causes problems with access to information. This paper presents the example of a rotating energy storage universal solution which is lack of the above mentioned disadvantages
Influence of magnetic saturation effects on the fault detection of induction motors
Authors: Drozdowski Piotr , Duda Arkadiusz 
Published: September 2014

Abstract
In this paper, the influence of impact damage to the induction motors on the zero-sequence voltage and its spectrum is presented. The signals detecting the damages result from a detailed analysis of the formula describing this voltage component which is induced in the stator windings due to core magnetic saturation and the discrete displacement of windings. Its course is affected by the operation of both the stator and the rotor. Other fault detection methods, are known and widely applied by analysing the spectrum of stator currents. The presented method may be a complement to other methods because of the ease of measurements of the zero voltage for star connected motors. Additionally, for converter fed motors the zero sequence voltage eliminates higher time harmonics displaced by 120 degrees. The results of the method application are presented through measurements and explained by the use of a mathematical model of the slip-ring induction motor

Published: September 2014

Abstract
The aim of the study was to find a possible way to measure the performance of sport horses based on their show jumping results and to estimate the heritability and repeatability values of these performances. The performance was measured with transformation of ranks, taking into account the number of starters at competition and the competition level. The used transformations were logarithmic, square root and an inverse normal transformation known as Blom method. Competitions were categorized into five groups based on their level of difficulty. The level of difficulty of the competitions was used as weighting factors, so performance traits were distinguished being weighted and non-weighted. Show jumping competition results collected between 1996 and 2011 were analysed. The database contained 358342 starts of 10199 horses. Identity number, name and gender of the horse, rider, competition year, the level and location of the competition and ranks were recorded in the database. The used repeatability animal model included fixed effects for age, gender, competition place, year of competition, and random effects for rider, animal and permanent environment effect. Variance components were estimated with VCE-6 software package. The goodness-of-fit of the models was low and moderate (0.09-0.47). Fitting models for weighted traits had better goodness-of-fit value. The best goodness-of-fit values were found in the case of level weighted variables. Heritability (0.02-0.07) and repeatability values (0.09-0.25) were low for each measurement variable.

Published: September 2014

Abstract
The objective of this study was to examine associations between milking temperament, parity and milk production traits in primiparous and multiparous dairy cows. Twenty-one primiparous and nineteen multiparous Holstein Friesian cows were involved in the investigation on a Hungarian dairy farm. Cows’ stepping behaviour, milk yield and average milking speed were recorded once a month over an entire lactation, during morning milking. Milking temperament was scored by direct human observation on a 5-point-scale (1=very nervous, 5=very quiet) during udder preparation and milking. Multiparous cows showed a little more excitable behaviour at milking than during udder preparation (Mann-Whitney U=14165.00, P=0.032), and they were calmer at premilking preparation than primiparous cows (Mann-Whitney U=14046.00, P=0.001). Milking temperament of multiparous cows during udder preparation was associated with milking speed: nervous cows let down their milk slower (F=9.102, df= 1, P=0.003). Further experiments are needed to repeat the milking temperament test along with sensors measuring heart rate variability of cows in order to better understand the milking behaviour of cows.

Published: September 2014

Abstract
This study was conducted to investigate the effects of Pleurotus eryngii stalk residue (PESR) on performance, egg traits and oxidative status of laying hens. One hundred and twenty 22-week-old laying hens (Hendrix) were randomly allocated into 4 dietary groups, each containing 30 birds, including 10 replicates per group and 3 birds per replicate. In addition, they were fed diets supplemented with 0 (control group, corn-soybean meal), 0.5, 1.0, or 2.0% dried PESR groups for 8 weeks, respectively. The results indicated that the different levels of dietary supplementation produced no significant differences in production performance among the experimental groups of laying hens. The Haugh unit was significantly higher in the 1.0% and 2.0% PESR groups compared to the control group. The eggs’ cholesterol content of the 1.0% and 2.0% PESR groups was significantly lower than that of the control group at 5-8 weeks. The blood triglyceride content and cholesterol content were significantly lower in the 1.0% and 2.0% PESR groups compared to the control group at the 4th and 8th weeks. Hence, the supplemented 1.0% and 2.0% of PESR groups showed higher levels for serum trolox equivalent antioxidant capacity, catalase and superoxide dismutase during the experimental period in comparison with the control group. This study indicated that a by-product of Pleurotus eryngii, PESR, could produce lower-cholesterol eggs and improve the oxidative stability with 1.0% and 2.0% PESR supplementation in laying hens.

Published: September 2014

Abstract
The chemical analysis of dried pomace of chokeberry, apple, black currant, strawberries and carrot was performed to determine the composition and content of nutrients and bioactive substances, among others the content of vitamins, phenolic acids, anthocyanins, and essential fatty acids. The antioxidant properties were determined in the extracts of pomace by determining the total antioxidant potential (TRAP) and antioxidant activity against DPPH radical. Tested pomaces contained 12-15% protein, approximately 18-20% crude fibre, approximately 2.7-4.0% ether extract and 1.8-3.0% ash. The highest level of anthocyanins was found in chokeberry pomace, followed by black currant pomace and several times less in strawberries and apples. The content of phenolic acids ranged from 12.91 mg/100 g in black currants to 630.30 mg/100 g in dried chokeberries. In terms of vitamins the richest source of vitamin E was chokeberry pomace (152.3 mg/100 g), while most of the carotenoids were found in dried carrot (15.35 mg/100 g). The chain of antioxidant activity was as follows: black currant>chokeberry>apple>strawberry>carrot, while in terms of antioxidative capacity it was chokeberry>apple>black currant>strawberry>carrot.
“Work curve” as a distinguishing mark of athletes’ work performance
Authors: Mikicin Mirosław 
Published: September 2014

Summary
Study aim: The aim of the study was to determine work performance in the aspect of work rate, energy, persistence, adaptation rate, and accuracy based on the indices of an athlete’s work curve.

Material and methods: Thirty athletes (15 women and 15 men) who practised five sports (swimming, track and field, fencing, judo, and taekwondo) and a control group (30 university students, 15 women and 15 men) participated in a work curve test (Kraepelin). Both groups were equivalent. They were aged 18–25 years, all of them had finished secondary education, and studied at the same university. The analysis concerned indices grouped into 6 factors: quantitative measures of performance, measures of energy and persistence, measures of quick adaptation and efforts without self-restraint, measures of variability, measures of accuracy and diligence, and measures of additional factors.

Results: Factor analysis of the work curve revealed a significant difference to the benefit of the athletes (p < 0.001) in the measures of energy and persistence. The results obtained in this study revealed good adaptation of athletes to exercise, resistance to fatigue, and quick process of learning.

Conclusions: The results obtained may reflect the adaptation of athletes to long-term physical activity. Therefore, they are characterized by greater involvement and patience. Therefore, it can be concluded that monotonous training that necessitates much energy, concentration of attention, and endurance, and, consequently, high work performance, is one of the most important predictors of athletic activity.
Potential Job Creation and Resource Dependance in Rural Finland
Authors: Lehtonen Olli , Tykkyläinen Markku 
Published: September 2014

Abstract
Despite strong secular economic growth after the crisis of 1990-93, most of rural Finland has continued to face severe job losses. By applying small-area analysis, this paper seeks to explain why some rural areas inevitably experience declining employment while others prosper and grow even faster than urban areas. The variation of job creation in rural small areas derives from local economic conditions, local demographic structure, proximity to larger centers, and natural conditions. Contrary to expectations, the coldest areas with nature reserves have passed the worst job loss. Those areas had a lower burden of declining primary industries than traditional agro-forest areas, and because of tourism, industry has expanded in some places in Lapland. The dependence of an area on the primary sector is a good indicator of the highest rural job losses during the urban-centric economic growth period. Especially the most resource dependent areas have lagged behind and fail in job creation on account of their uncompetitive industrial environment. Persistent labor surplus plagues such areas, implying that established policy measures have been unable to restructure and modernize traditional rural areas. Since Finnish rural and regional policies have been being inefficient they should be reformed especially in resource-based areas in a fundamental way.

Published: September 2014

Abstract
The article shows the results of the case study of Postira, a village and a municipality on the island of Brač (Croatia) and presents a positive example of sustainable community development on islands in the post-transition social context. Based on the theory of sustainable local community development and its four pillars (economic, ecological, social and cultural), we analyse both the secondary data and the primary data collected from semi-structured interviews with the key actors of local development. The study shows that economic, ecological, social and cultural domaines are connected in Postira which allows for sustainable development of the place. By examining various aspects of sustainable development in Postira, we present the general framework of sustainable island development. It is based on integral development of the local community on sustainability principles, it defines key processes and guidelines and can be applied to rural and island areas, taking into account the specificities of each community.

Authors: Graf Renata , Przybyłek Jan 
Published: September 2014

Abstract
In the paper we present the results of shallow groundwater recharge estimation using the WetSpass GISbased distributed water balance model. By taking into account WetSpass, which stands for Water an Energy Transfer between Soil, Plants and Atmosphere under quasi-Steady State, for average conditions during the period 1961-2000, we assessed the spatial conditions of the groundwater infiltration recharge process of shallow circulation systems in the Poznan Plateau area (the Great Poland Lowland in western Poland), which is classified as a region with observed water deficits. For three temporal variants, i.e. year, winter and summer half-years, we determined using the geological infiltration method by about 5-10% on average, marginally by 20%.

Published: September 2014

Abstract
The paper presents the outcomes of the uncertainty investigation of a long-term forest cover change analysis in the Polish Carpathians (nearly 20,000 km2) and Swiss Alps (nearly 10,000 km2) based on topographic maps. Following Leyk et al. (2005) all possible uncertainties are grouped into three domains - production-oriented, transformation- oriented and application-oriented. We show typical examples for each uncertainty domain, encountered during the forest cover change analysis and discuss consequences for change detection. Finally, a proposal for reliability assessment is presented.
Regional Differentiation in Probability of Ice Days Occurrence in Poland
Authors: Łupikasza Ewa , Niedźwiedź Tadeusz , Małarzewski Łukasz 
Published: September 2014

Abstract
This paper aims at recognizing spatial differentiation in probability of ice days occurrence with reference to atmospheric circulation, using regional classification of circulation types for Poland. Daily maximum air temperatures measured at nine meteorological stations were used to recognize the ice days occurrence in the period from January 1951 to March 2014. The relations between the ice days occurrence and atmospheric circulation were analysed using catalogues of circulation types compiled for nine grid boxes within Poland. Linkage between the frequency of ice days and atmospheric circulation was recognized in the period of January 2001 - March 2014. A decreasing tendency in the frequency of the occurrence of winter ice days was found. The occurrence of ice days in Poland is clearly related to atmospheric circulation. In the entire area of Poland their occurrence is favoured by eastern and south-eastern advection of air during anticyclonic conditions (types Ea nad SEa). Regional variability is also noticeable.
Temporal Variation in Vegetation Indexes for Pine and Beech Stands During the Vegetation Season, Szczecin Lowland, Poland
Authors: Piekarski Paweł , Zwoliński Zbigniew 
Published: September 2014

Abstract
Located in north-western Poland, the Bukowska Forest and Goleniowska Forest are vast woodlands consisting of areas with a homogeneous species composition that have been scarcely affected by humans. In this respect, they provided an excellent subject for scientific research, the purpose of which was to determine quantitative differences in selected vegetation indices of pine and beech stands in various periods during their vegetation seasons. Another purpose was to characterize the variation in these indices for each stand in its vegetation season. Four Landsat 5 TM images taken in 2007 and 2010 at four different points of vegetation season provided the basis for the analysis. In the analysis, 19 wooded areas with a homogeneous species composition were tested. In Bukowska Forest, the tested area was a beech stand, and in Goleniowska Forest, it was a pine stand. Acquired data was used to calculate the following vegetation indices: Normalized Difference Vegetation Index (NDVI), Transformed Vegetation Index (TVI), Green Normalized Difference Vegetation Index (Green NDVI), Normalized Difference Greenness Index (NDGI) and Normalized Difference Index (NDI). Subsequent research allowed to establish that the beech and pine stands differed significantly with respect to their calculated vegetation indices. These differences derived both from the biochemical and structural attributes of leaves and needles, as well as from transformations that occur in the stands during vegetation seasons. Analysis of the indices’ allowed us to determine these differences and the influence of the stands’ phenological phases on the indices.

Published: September 2014

Abstract
An overview of palaeogeographical findings of the last glacial period (MIS 5d-MIS 2) has been given for the Łódź region. Processes which influenced the area outside of ice-sheet margin are presented with respect to space and time, as predominantly driven by different types of periglacial environment. Attention was paid to leading accumulative and erosional processes and resulting landforms, still well-pronounced in the landscape. Recently, the picture of the area discussed, during the Vistulian was completed and identified was the mechanism of the LGM ice-sheet advance onto the Płock lobe. Borderline location of the Łódź region offers comprehensive research on the time and processes and determines its significance on the geomorphological map of Poland.

Published: September 2014

Abstract
Geomorphosites are among major assets for the development of geotourism. An accurate assessment of spatial distribution of their scientific, educational and economic characteristics provides the basis for appropriate design and management of proposed geoparks. Although the problem of assessing their value for geotourism has been discussed by numerous authors, consistent methodology for the assessment of geomorphosites has not been devised so far. In the present study, we conducted a geotourist evaluation of geomorphosites located within the proposed geopark Vistula River Gap. We assessed a total of 76 sites using 18 assessment criteria. The results indicate not uniform spatial distribution of sites having the highest value. The application of cluster analysis to evaluation results enabled us to distinguish groups of sites with similar characteristics and thus to identify groups of geomorphosites in relation to which various measures should be taken in order to increase the possibilities of their tourist use.
The Sources of Moisture in the Sand Dunes – The Example of the Western Sahara Dune Field
Authors: Żmudzka Elwira , Woronko Dariusz , Dłużewski Maciej 
Published: September 2014

Abstract
Climatic and meteorological conditions may limit the aeolian transport within barchans. An explanation of that issue was the main goal of the investigation held in Western Sahara dune fields located around Tarfaya and Laâyoune. Particular attention was paid to the factors causing the moisture content rising of the sand dune surface layer, which could influence the wind threshold shear velocity in the aeolian transport. The wetted surface layer of sand, when receiving moisture from precipitation or suspensions, reduces the aeolian transport, even in case of wind velocity above 4-5 m s-1. Fog and dew condensation does not affect the moisture of deeper sand layers, what occurs after rainfall.
