Authors: Kessler Jenő (Eugen) 
Published: January 2016

Abstract
The author provides an osteological guide to songbirds, based on 11 skeletal parts of 51 genera, at the genus level for ornithologists studying owl pellets, paleontologists and archaezoologists. The mandible, the coracoid bone, the scapula, the humerus, the ulna, the carpometacarp, the first phalanx bone of the second finger, the femur, the tibiotars, the tarsometatars and the claw bone are presented.
The morphological characteristics and method of measurement of the examined skeletal parts and the photographs of the appropriate bones are illustrated on 52 plates and 17 figures. The measurement data are also provided in 11 size tables. For every discussed bone, 3-6 characteristics are chosen, and their codes consist of 3-6 letters. In case of overlaps, dimensions are the determining factors, and for the humerus and the ulna, the ensemble of the two bone end pairs can be used.

Published: January 2016

Abstract
Total of 54 samples (of sediments taken from the surface of 5-cm layer of profundal zone of lakes in the catchment of the river Brda) were tested in presented research. The collected samples were analysed for the concentrations of Ag, As, Ba, Cd, Co, Cr, Cu, Ni, Pb, Sn, Sr, V and Zn, and Al, Ca, Fe, Mg, Mn, P and S, using inductively coupled plasma atomic emission spectroscopy (ICP-AES), after sample digestion in aqua regia. The Hg concentration was determined from solid samples using atomic absorption spectroscopy (TMA). The organic carbon content was determined using the coulometric method. Sediments of most of lakes examined in the Brda catchment area are characterised by low concentrations of trace elements. Sediments contained an average of 0.9 mg/kg of Cd, 0.107 mg/kg of Hg, 8 mg/kg of Ni, 46 mg/kg of Pb, 8 mg/kg of As, 78 mg/kg of Ba, 12 mg/kg of Cr, 94 mg/kg of Zn, 3 mg/kg of Co, 12 mg/kg of Cu, 1.3 mg/kg of Mo, 105 mg/kg of Sr and 16 mg/kg of V. The presence of elevated concentrations of chromium, copper, nickel and vanadium is controlled by a geogenic factor - weathering of glacial deposits containing fragments of igneous and metamorphic rocks which are the source of heavy metals. The presence of elevated contents of Pb, Zn, Hg and Cd is caused by anthropogenic factor. Most of the lake sediments show low concentrations of As, Cd, Cr, Cu, Hg and Ni, which do not pose a threat to aquatic organisms. The concentrations of lead in almost half of the samples are elevated to a level at which a negative effect of this element can be observed. In the case of zinc, the proportion of such samples is about 25%.
Effect of copper upon the actions of sulphate-reducing bacteria isolated from soil contaminated by crude oil and heavy metals / Wpływ miedzi na aktywność bakterii redukujących siarczany wyizolowanych z gleby zanieczyszczonej ropą naftową i metalami ciężkimi
Authors: Podobas Ewa Izabela , Rożek Agnieszka 
Published: January 2016

Abstract
In the present study, copper tolerance by a mixed culture of sulphate-reducing bacteria (SRB) were evaluated. These sulphidogenic microbial communities were isolated from soils polluted by crude oil, oil-derived products and heavy metals (from selected areas of crude oil mines in south-eastern Poland).
Copper tolerance of SRB was tested in modified Postgate C medium with ethanol and lactate as the sole carbon source and copper chloride at concentrations ranging from 0 to 1500 mg/l. Bacterial growth and sulphate reduction were possible between 100 and 1500 mg/l of initial copper concentration. Active sulphate reduction - maximum of 53% was observed in the cultures.
Molecular analysis indicated not only the presence of SRB but also other microorganisms that are capable of living in environments contaminated by heavy metals. The high environmental sulphide concentrations produced by SRB lead to the precipitation of any biogenic mineral phases such as metal sulphides. As a result, soluble metal ion concentrations in the microenvironment of SRB are, therefore, extremely low. This process allows SRB to grow in environments containing high levels of toxic metals. Studies on SRB tolerance to heavy metals are extremely important because of the possibility of using this group of microorganisms for the bioremediation and microbial revitalisation of areas contaminated by heavy metals.

For Want of a Nail: Three Tropes in Data Curation
Authors: Shankar Kalpana 
Published: January 2016

AbstractThis article explores the role of three key tropes in the data curation profession. Using interviews with digital preservation experts, researchers, public sector statisticians, and social science data archivists as well as popular and professional literature and media, this article discusses how tropes and narratives are used to create shared meaning among data curation stakeholders. The article explores how tropes of abundance / overload, openness, and trust are created and used and concludes with reflections on how such stories articulate professional values and concerns. The article advocates for further attention to the use of narratives and stories as the data curation profession develops.
The principle of system Corefit in rehabilitation of pelvic floor disorders for women in menopause period
Authors: Żak I. , Saulicz E. , Linek Paweł , Saulicz M. 
Published: January 2016

Abstract
Background: Pelvic floor dysfunctions, among which urinary incontinence is the most onerous symptom, pose a serious social problem whose significance is probable to grow together with the process of an ageing society and more frequent incontinence episodes in menopausal women. The growing absence of professionally active people suffering from incontinence is prone to result both from plans to raise the retirement age and the process of an ageing society. The concept of Corefit system has been created to meet the incontinent women’s expectations. The above mentioned system is based on an individualized sensomotoric training programme as well as the re-education of incorrect motor patterns resulting in pelvic floor muscle overload. What is also essential for Corefit system effectiveness is monitoring the process of facilitation, which enables constant training plan correction.

Authors: Doroniewicz I. , Matyja M. , Durmała J. , Pastuszak J. 
Published: January 2016

Abstract
Background: Regular physical therapy of people with Down syndrome improves the efficiency of such treatment. However, it remains unclear whether a discontinuation of the therapy over the period of summer holiday influences the effects of the therapeutic process. The aim of this study was to evaluate the effect of summer holiday on postural tone and quantitative parameters of body posture (angle of trunk rotation in the transverse plane and the spinal curvatures such as kyphosis or lordosis in the sagittal plane) in young people with Down syndrome.
Material/Methods: Twenty one people aged 14 to 24 years were examined, with IQ scores from 54 to 35 on the Wechsler Intelligence scale. The experimental group was young people with Down syndrome whereas the control group were people with moderate intellectual disability without additional neurological, orthopaedic and other genetic disorders. The postural tone coefficient (PTC) and values of the spinal curvature (lordosis and kyphosis) and angle of trunk rotation (ATR) were evaluated twice. The first measurement was performed after 10 months of regular neurorehabilitation according to the neurodevelopment concept while the second - after 2 months of summer holiday.
Results: During the holiday, the PTC value reduced significantly in the controls, from 0.40 to 0.37 (p=0.02), whereas in young people with Down syndrome, postural tone did not change significantly (p=0.33). In terms of the parameters of body posture, one significant change was observed in the group of patients with Down syndrome (kyphosis, p=0.00).
Conclusions: No significant correlations were found between postural tone and values of kyphosis, lordosis and angle of trunk rotation, except for the relationship between PTC and angle of trunk rotation obtained in the main thoracic measurement (Th5- Th12, p=0.03).
Simulation of the steady-state behaviour of a new design of a single planar Solid Oxide Fuel Cell
Authors: Pianko-Oprych Paulina , Zinko Tomasz , Jaworski Zdzisław 
Published: January 2016

Abstract
The aim of the work was to develop a mathematical model for computing the steady-state voltage – current characteristics of a planar Solid Oxide Fuel Cell and to determine the performance of a new SOFC design. The design involves cross-flow bipolar plates. Each of the bipolar plates has an air channel system on one side and a fuel channel system on the other side. The proposed model was developed using the ANSYS-Fluent commercial Computational Fluid Dynamics (CFD) software supported by additional Fuel Cell module. The results confirm that the model can well simulate the diagonal current path. The effects of temperature and gas flow through the channels and a Membrane Electrode Assembly (MEA) structure were taken into account. It was shown that a significant increase of the MEA temperature at high current density can lead to hot spots formation and hence electrode damage.
Effect of notch sensitivity on the mechanical properties of HA/PEEK functional gradient biocomposites

Published: January 2016

Abstract
Biomaterials used as loading-bearing orthopedic implants usually require various excellent properties such as mechanical, bioactive and bio-tribological performances. Moreover, all of the orthopedic applications feature stress concentrations (notch sensitivity) in their design. In the present work, hydroxyapatite-reinforced polyetheretherketone functional gradient biocomposites (HA/PEEK FGBm) were successfully prepared by the layer stacking method combined with hot pressing molding technology. The effects of notch geometry on the stress-strain behavior of HA/PEEK FGBm were evaluated. The fracture morphology was investigated by scanning electron microscopy (SEM). The study of the stress-strain behavior indicated that the tensile and flexural stresses of HA/PEEK FGBm linearly increased with increasing strain under all the notch sensitivities. The fracture strain of the biocomposites decreased with increasing stress concentration factor and total HA content in the functional biocomposites. Moreover, the tensile and flexural strengths of HA/PEEK FGBm were lower than those of homogeneous HA/PEEK biocomposites. The SEM observation of the fracture micro-morphology showed that the fracture mechanism of HA/PEEK FGBm was gradually controlled by the brittle fracture process. Furthermore, both the tensile and the flexural strengths of HA/PEEK FGBm decreased with the increase in stress concentration factor and total HA content in the biocomposites.
Effect of surface modification on the compressive properties of silica fume/polyurethane composites
Authors: Shao Di , Diao Jianzhi , Wang Lijie , Li Long 
Published: January 2016

Abstract
Silica fume was modified by a silane coupling agent (KH-550). The modified silica fume was further investigated to reinforce polyurethane (PU) composites. Unmodified and modified silica fume reinforced PU composites were prepared. Through the comparisons of Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) of unmodified and modified silica fume, the agglomerations of silica fume particles were effectively prevented as KH-550 was grafted. The compressive strength of the modified silica fume/PU composites was largely improved, because KH-550 could react with both silica fume and PU. Meanwhile, modified silica fume turned from hydrophilic to hydrophobic; a better dispersion was realized in the PU elastomers compared to the unmodified silica fume. The reinforcement effects were evaluated based on the results of a universal test machine in comparison with unmodified silica fume/PU composites.
How do Members of Parliament View the Public Value of Public Service Media? The Case of Latvia
Authors: Brikše Inta , Beitika Ieva 
Published: January 2016

Abstract
The Development of public media in Latvia as a post-communist country has essentially been influenced by politicians. The political community has had consensus that certain reforms are necessary to ensure the development of public media given the changes in the communication space and its role in the facilitation of the strengthening of democracy, yet during the last fifteen years the political elite has not been able to come to a common agreement and to make decisions on systemic reforming and the development of public media. Since the communication environment has changed post digitalisation of television, the question about public media development and legitimisation has become increasingly topical.
The aim of the study is to explore how the members of the parliament of Latvia (Saeima) position public service media (PSM) in Latvia and assess the public value of PSM. The theoretical framework for the research is based on the concept of public value „strategic triangle” (Benington & Moore 2011), which consists of three main elements: public value outcomes, the authorising environment and operational capacity.
The study is based on qualitative research methods including 18 semi-structured interviews conducted with members of the Saeima in 2012 and 2013. The acquired data has been analysed by the principles of thematic analysis (Attride-Stirling 2001). Analysis of the interviews show that members of the Saeima recognise the need for public media to be independent whilst at the same time supporting a model in which public media is not supposed to have independent funding and they will continue competing with commercial media in the advertising market. High competition and resentment are characteristic features of the political elite in Latvia that apparently would also in future hamper the making of such decisions about public media that will facilitate their high-quality. Results of the research show the tendency for members of parliament to lack the necessary knowledge to formulate their opinion and to modulate relations of public media with society and their place in the overall media system in Latvia.
Mechanisms of Europeanisation and Compliance in Judicial Politics: Understanding the Past and Anticipating the Future
Authors: Coman Ramona 
Published: January 2016

Abstract
Recent developments in Hungarian constitutional and judicial politics have given impetus to question not only the outcomes of democratisation and Europeanisation, but also the efficacy of the European Union’s compliance mechanisms. In 2010, Hungary, one of the forerunners in building democracy made the headlines with Fidesz’s attempts at adopting a new Constitution and implementing cardinal laws along with controversial institutional, cultural, religious, moral and socio-economic policies. This article attempts to depict the transformative power of the European Union within a sensitive policy area which touches upon States’ pouvoris régaliens: the independence of the judiciary.
Legitimacy through Subsidiarity? The Parliamentary Control of EU Policy-Making
Authors: Borońska-Hryniewiecka Karolina 
Published: January 2016

Abstract
This article explains the relationship between subsidiarity and legitimacy of policies designed at EU level. Through means of theoretically informed analysis this paper claims that if the principle of subsidiarity is respected and implemented throughout the policy process, EU policy-making can aspire to satisfy the condition of both input and output legitimacy. The empirical part of the paper shows how, through a subsidiarity control mechanism known as the Early Warning System, national parliaments can collectively fulfill representative and deliberative functions in EU policy-making. Conclusions about the changing dynamics in parliamentary modus operandi in the field of EU affairs lead to forming a set of recommendations for further research.

Authors: Kuczera Piotr , Adamczak Marcin , Wiecek Andrzej 
Published: January 2016

Abstract
In patients with chronic kidney disease the alterations of the endocrine system may arise from several causes. The kidney is the site of degradation as well as synthesis of many different hormones. Moreover, a number of concomitant pathological conditions such as inflammation, metabolic acidosis and malnutrition may participate in the pathogenesis of endocrine abnormalities in this group of patients. The most pronounced endocrine abnormalities in patients with chronic kidney disease are the deficiencies of: calcitriol, testosterone, insulin-like growth factor and, erythropoietin (EPO). Additionally accumulation of several hormones, such as: prolactin, growth hormone and insulin frequently also occur. The clinical consequences of the abovementioned endocrine abnormalities are among others: anemia, infertility and bone diseases.

Abstract
In the recent years it has been confirmed that the main component of the immune response in an injury of the nerve cell comes from microglia and macrophages. The main challenge in the field of microglia research is to detect the different stages of cellular activation by visualization of the cell morphology. The existing visualization techniques are based on surface molecules expression in resting and activated microglia cells. For visualization of the microglial cells and their functional state we used double labeling method for cd-68 and iba1 in brain contusions with different survival time. Microglia are stained brown with Iba-1, whereas microglia impregnated with black, grainy color, represents activated microglia stained with CD 68. We had significantly positive results, and we were able to observe changes in the morphology of the microglia that correlated with the survival time. Using double labeling with Iba-1 and cd68 we were able to determine their physiological state based on the morphology and immunoreactivity.
Overdentures on Implants for Better Quality of Life Among the Fully Edentulous Patients – Case Reports
Authors: Nikolovska Julijana , Petrovski Dragan , Petricevic Nikola , Kapusevska Biljana , Korunoska-Stevkovska Vesna 
Published: January 2016

Abstract
Global aging population has brought several challenges for their medical systems and total edentulism is one of them. The fabrication of removable acrylic dentures seems to be a simple and cheap treatment solution, but a majority of patients is not satisfied with their functional instability, causing limited diets, mouth soreness, speech and psycho-social problems etc. The results in many studies indicate an impact of oral conditions associated with the full denture wearing on oral-health related quality of life, especially in lower jaw. The reason for improper denture retention could be alveolar ridge bone resorption and numerous studies about this problem are plausible. Bone resorption in lower jaw may turn the alveolar ridge into a flabby soft tissue which is unable to sustain proper denture retention.
The implant-retained prosthesis is an alternative treatment option in these situations. Implants will provide retention, stability, function and aesthetics and they are not so expensive solution. The aim of this article is to show solving of retention problems of a lower denture in two different clinical cases using implants and without any special technology.
First Off-Shore Site Bird Monitoring In Poland (Debki-Białogóra, 2002–2004)
Authors: Busse Przemysław 
Published: January 2016

Abstract
Due to the presence along the Polish Baltic coast of migratory bird flyways from north-eastern European breeding grounds to wintering areas distributed on continental shelf waters of western and southwestern Europe, the area has been designated as a NATURA 2000 site (PLB 990002). Therefore the site of a planned off-shore wind farm in this area requires monitoring as to its potential influence on birds. This was the first such monitoring performed in Poland. The expanse of water covered by the research included the planned location of the wind farm as well as adjacent areas. A series of 15 investigative cruises were undertaken from the beginning of October to the beginning of May. The period of observations was divided into five seasons: early autumn, late autumn, winter, early spring and late spring. The standard method of counting birds on transects in the form of strips reaching 300 m from the ship was used in the research, as well as the ‘snapshot’ technique (scan with bands transect with snapshot technique). Additional observations were made from a point on the shore.
In the study area maritime birds are present in low or moderate densities, with localized clusters. Two diving benthophagous species dominate: the Long-tailed Duck (58.9%) and the Velvet Scoter (34.3%). The next two commonest species have a share of over 1% within the community – the Common Scoter (3.2%) and the Herring Gull (2.4%). Other species are very uncommon. There is very high fluctuation in the number of birds both observed on the water surface and seen in the air. In the area studied no pronounced migratory passage of waterfowl was observed; the usual migratory flyways probably lie farther to the north and the birds observed in flight perform mainly local movements. Observed bird densities in the study area are considerably lower (52.0 ind./km2) than those estimated for the entire NATURA 2000 area (116.7 ind./km2). In the area of the planned wind farm densities are even lower (36.1 ind./km2, i.e. 31% of the NATURA 2000 level), while densities in neighbouring areas are still below the NATURA 2000 average.
In the subsequent administrative procedure the area was not accepted as the location of the planned wind farm.
