Authors: Cotigă Carmen , Bologa Octavian , Deac Cristian 
Published: January 2015

Abstract
Incremental forming is a novel but promising procedure for the flexible manufacturing of parts starting from metal sheets. It could be very useful in the medical area and especially in orthopedic prosthetics, where each part needs to be very precisely made, but at the same time has to have a unique shape. In this context, the selection of the material that could best satisfy the manufacturing and usage requirements is very important. The current paper suggests a unified parameter that could be used for assessing the suitability of a specific material for the manufacturing, by incremental forming, of prosthetic parts that would be used in human surgery

Published: January 2015

Abstract
Reducing the concentration of lead ions in a wastewater using zeolite has proven to be a successful water treatement method, all over the world. Putting the two media (solid and liquid) in contact in static conditions had good results regarding the concentration of the filtered solution, the pH and the electric conductivity, depending on the values of certain parameters such as the amount of the zeolite, volume of the solution or interaction time. The present study highlights the zeolite ability to retain the lead ions from a solution, in dynamic interaction conditions between the two environments, in a short interaction time. The results confirmed the effectiveness of ion exchange water treatment method in the conditions set, emphasizing once again the properties of the filter material - the zeolite

The Ås Temperature Series in Southern Norway–Homogeneity Testing And Climate Analysis
Authors: Gjelten Herdis M. , Nordli Øyvind , Grimenes Arne A. , Lundstad Elin 
Published: January 2015

Abstract
Homogeneity is important when analyzing climatic long-term time series. This is to ensure that the variability in the time series is not affected by changes such as station relocations, instrumentation changes and changes in the surroundings. The subject of this study is a long-term temperature series from the Norwegian University of Life Sciences at Ås in Southern Norway, located in a rural area about 30 km south of Oslo. Different methods for calculation of monthly mean temperature were studied and new monthly means were calculated before the homogeneity testing was performed. The statistical method used for the testing was the Standard Normal Homogeneity Test (SNHT) by Hans Alexandersson. Five breaks caused by relocations and changes in instrumentation were identified. The seasonal adjustments of the breaks lay between -0.4°C and +0.5°C. Comparison with two other homogenized temperature series in the Oslo fjord region showed similar linear trends, which suggests that the long-term linear temperature trends in the Oslo fjord region are not much affected by spatial climate variation.
Spatial Differentiation Of Global Solar Radiation in Toruń And its Suburban Area (Central Poland) in 2012
Authors: Kejna Marek , Uscka-Kowalkowska Joanna , Araźny Andrzej , Kunz Mieczysław , Maszewski Rafał , Przybylak Rajmund 
Published: January 2015

Abstract
: This article investigates the spatial distribution of global solar radiation (K↓) in Toruń and its suburbs, observed in 2012. Measurements were taken at 12 points (7 within the city and 5 in the suburban area) using CNR4 net radiometers and automatic weather stations (Vantage Pro+). At all locations, the diurnal and annual courses of K↓ were typically related to the Earth’s rotational movement and changes in the sun’s declination over the year, and disturbed by clouds and atmospheric phenomena that enhance the extinction of solar radiation. A substantial spatial diversity of K↓ was observed in Toruń and its suburbs. The annual sum of K↓ at several urban locations accounted for over 70% of the solar radiation in the open space outside the city. The amount of incoming solar radiation in the urban area was more restricted in winter (<50%) than in summer (approx. 70%). The diurnal courses of K↓ were heavily disturbed by local obstacles which cast shadows (causing a considerable decrease of K↓), but there were instances of increases in K↓ (122%) augmented by radiation reflected from roofs, walls and windows surrounding the measurement point. The spatial diversity of K↓ in the urban area is heterogeneous, due to local meteorological conditions (cloudiness, fog, smog and airborne dust) and the obscuring of the horizon.
Water Temperature and its Diversity in the Deepest Lakes of the Tuchola Forest and the Kashubian and Brodnickie Lakelands
Authors: Skowron Rajmund , Piasecki Adam 
Published: January 2015

Abstract
This study presents the results of monthly examinations of the vertical distribution of water thermal structure (2008-2011) carried out over a four-year period in the deepest lakes located in the Kashubian and Brodnickie Lakelands and the Tuchola Forest1. Three lakes were selected for examination (Raduńskie Górne, Zbiczno and Ostrowite). Their maximum depths slightly exceed 40 m, and their surface areas range from 121 to 362.5 ha. The results of the measurements show that, despite only minor differences in depth, water temperature varied significantly between the studied lakes. These differences were mainly apparent in the extent of the epilimnion, water thermal stratification, and in the water temperature in the bottom-most layers in summer and winter. The diversity in thermal stratification of the lakes is mainly determined by their morphometric properties, their location above sea level, and the dynamic influences of winds.
Variability of Geological and Engineering Conditions in River Valleys: The Example of The Upper Vistula River Valley
Authors: Labak-Mechowska Ewa 
Published: January 2015

Abstract
Fluctuations in groundwater levels are usually associated with the seasonal variability of precipitation and evapotranspiration. This has an effect on the carrying capacity of soil and on foundation engineering structures in river valleys. The analysis concerns the example of the Upper Vistula River valley. It presents the geological, groundwater and geological engineering conditions of the researched area through seasonal variations in groundwater level. Based on the results of soil and groundwater analyses, a preliminary assessment was made of the bearing capacity and aggressiveness of the water. An analysis of steel and concrete construction elements was carried out. It was estimated that precipitation has an influence on the strength parameters of soil. With a rise of the groundwater table, physical and mechanical parameters deteriorate. However, a drop in the level of the groundwater table causes an improvement in the strength parameters of soil.

Authors: Hebisz Paulina , Hebisz Rafal , Zaton Marek 
Published: January 2015

AbstractBackground: The purpose of this study was to compare body balance in road and off-road cyclists, immediately before and after the racing season.Material/Methods: Twenty individuals participated in the study and they were divided into two groups: specialists in road-cycling (n = 10) and in off-road cycling (n = 10). Immediately before and after the five-month racing season stabilographic trials were carried out (at rest and after progressive exercise). In assessing body balance the distance and velocity of the centre shifts (in the anterior-posterior and left-right direction) were analysed. The tests were performed with the cyclists’ eyes open, eyes closed, and in feedback.Results: After the racing season, in the off-road cyclists’ group, distance and velocity of the centre of pressure shifts increased after a progressive exercise.Conclusions: In the off-road cyclists’ group the balance of the body in the sagittal plane deteriorated after the racing season. Moreover, after the racing season off-road cyclists were characterized by a worse balance of the body, compared to road cyclists
Are changes in HSPA1A, HSPB1 and LDHb genes expression during physical performance ”till exhaustion” independent of their exercise possibility?
Authors: Jastrzebski Zbigniew , Zychowska Malgorzata 
Published: January 2015

AbstractBackground: The aim of the study was to designate changes in the expression of HSPA1A, HSPB1 and LDHb in elite rowers after completing a test “till exhaustion” on a rowing ergometer. Finally, we searched for the answer whether there are significant correlations between the expression of the genes and anaerobic threshold (AnT) or the maximal oxygen uptake (VO2max).Material/Methods: The research was conducted on the sample of 9 Polish lightweight male rowers (23.7 ±3.77 yrs, 72.7 ±1.76 kg, 183.6 ±4.58 cm). To determine AnT and VO2max, the subjects performed the test “till exhaustion” with an increasing load on a rowing ergometer. Directly before and after the test, blood samples were collected from the ulnar vein in order to isolate genetic material. RNA was extracted from white cells of venous blood by the chemical method. 2 μg RNA for the reverse transcription was used and the expression of HSPA1A, HSPB1 and LDHb was determined by Real time PCR reaction. To assess the intensity of expression, the ΔΔCt method was used.Results: The study showed an increased expression of HSPA1A and HSPB1 and a decreased one of LDHb. Moreover, post-training changes of the genes activity in white blood cells occurred immediately and could be determined directly after the termination of exertion.Conclusions: No significant correlations between the expression of the genes and anaerobic threshold (AnT), maximal oxygen uptake (VO2max) were stated

Published: January 2015

AbstractBackground: The origin and prevalence of cerebral palsy can hardly be considered fully understood. The relationship between orthopedic and neuropsychiatric disorders in children with cerebral palsy in the available literature is also insufficiently presented.Material/Methods: Authors conducted a clinical and epidemiological analysis and examined the nature of motor disorders in 267 children with cerebral palsy aged from 3 to 16 years old. The monitoring period of patients ranged from 3 to 7 years. They underwent clinical neurological examination, radiography of the spine and joints, ultrasound examination of the joints and periarticular structures, electroencephalography and electroneuromyography in dynamics, with the help of a variational cardiointervalography characterized by an autonomic dysfunction (Veyn AM, 2000), studied the biomechanical parameters of walking, using scorecards, questioning and evaluate the effectiveness of the treatment using the special system to cerebral palsy (Pinchuk D Yu, Dudin MG, 2002).Results: In 80% of cases, brain damage occurred during fetal development. The authors distinguished primary and secondary disorders of movements. 71 persons (26.6%) had neurogenic and myogenic contractures, and in 196 people (73.4%) contractions were exacerbated by bone deformities. In the rehabilitation system 163 people (61 %) had a need for a surgical operation.Conclusions: The efficiency ratio of the functional status after rehabilitation in different age groups has improved by 10-22% more than before the treatment. It was shown objectively that improvement in the motor capacity in patients with cerebral palsy due rehabilitation has a positive effect on the function of the cerebral cortex

Authors: Kocjan Janusz , Knapik Andrzej 
Published: January 2015

AbstractBackground: Comprehensive cardiac rehabilitation (CR) is a process designed to restore full physical, psychological and social activity and to reduce cardiovascular risk factors. Fear of movement may contribute to the occurrence and intensification of hypokinesia, and consequently affect the effectiveness of therapy. The aim of the study was to determine the level of barriers of physical activity in patients undergoing cardiac rehabilitation. The relationship between selected determinants (age and health selfassessment) and the kinesiophobia level were also examined.Material/Methods: 115 people aged 40-84 years were examined: 50 females (x = 63.46; SD = 11.19) and 65 males (x = 64.65; SD = 10.59) - patients undergoing cardiac rehabilitation at the Upper-Silesian Medical Centre in Katowice. In the present study, the Polish version of questionnaires: Kinesiophobia Causes Scale (KCS) and Short Form Health Survey (SF-36) were used. Questionnaires were supplemented by authors’ short survey.Results: The patients presented an elevated level of kinesiophobia, both in general as well as in individual components. In women, the kinesiophobia level was higher than in men. The psychological domain was a greater barrier of physical activity than the biological one. Strong, negative correlations of psychological and biological domains of kinesiophobia to physical functioning (SF-36) were noted in women. In the case of men, correlations were weaker, but also statistically significant.Conclusions: 1. Sex differentiates patients in their kinesiophobia level 2. Poor self-assessment of health is associated with a greater intensification of kinesiophobia 3. A high level of kinesiophobia may negatively affect cardiac rehabilitation process
The influence of intention implementation on throw effectiveness of young basketball players
Authors: Wilczynska Dominika , Lipinska Patrycja , Wolujewicz-Czerlonko Malgorzata 
Published: January 2015

AbstractBackground: The purpose of the following research was to find out the influence of imaginary training based on intention implementation on throw effectiveness of young basketball players, both male and female in stressogenic situations. Individual differences (action vs state orientation) between players were also measured in this research.Material/Methods: 76 players (32 females and 44 males) in the cadet category (15-16 years old) from basketball clubs of Gdansk, Gdynia and Sopot took part in this research. In the first stage all players did a throw efficiency test ERPE 05 under two conditions, and their heart rate was measured. Then players were randomly assigned to one of two groups. The first one did imaginary training based on the influence of intention implementation for 10 days, while the other did not. After 10 days ERPE 05 test under two conditions was run again.Results: Test results showed that intention implementation does not influence effectiveness improvement in stressogenic conditions as far as state-oriented players are concerned, but it does lower the physiological cost of physical effort in form of a decreased heart rate.Conclusions: This research proves that visualization training based on implementation instructions does influence young players’ physiology and significantly lowers their heart rate under stressogenic conditions. However useful, visualization techniques used in this research still need other tests and should be applied for a longer period of time to acutely show how they affect young players’ mental preparation
Journalism as a means to Reconciliation. Paul Schiemann’s Essays 1919–20
Authors: Housden Martyn 
Published: January 2015

Abstract
Paul Schiemann was one of the most significant ethnic Germans left outside the German state by the post-First World War peace settlement. As editor of Rigasche Rundschau and an active politician in the new Latvian state, he was well placed both to comment on developments in the political life of the Baltic region and to attempt to work towards responses to them. This article focuses specifically on his journalism during the critical years 1919-20. As the Latvian state was forming against a background of considerable on-going violence and instability, Schiemann disseminated consistently a call for reconciliation between Latvia’s mutually suspicious national groups. The paper examines the compelling arguments he used.

Numerical Simulation of Thermal Energy Storage in Underground Soil Heat Accumulator
Authors: Kortiš Ján , Gottwald Michal 
Published: January 2015

Abstract
The alternative energy sources have been getting popular for last decades as a new way to obtain enough energy especially for countries which do not have rich natural reservoirs of fossil fuels. Gathering the thermal energy from the solar radiation seems to be as one of the cheapest alternatives of them. The disadvantage of it is the overflow of the heat energy during the summer and lack of them during the winter, when the demand for heat is on top. The underground thermal energy storage can be a good alternative for accumulating the heat energy and then offers it on demand. However, it is difficult to monitor the real physical condition in the soil. In the article, the results of numerical simulation are shown as a good way for a better identification of the process of accumulating the energy to the soil material.
