Management of the behavioural manifestations of Hunter syndrome
Authors: Roberts Jane , Stewart Catherine , Kearney Shauna
Published: January 2016

This article reviews the behavioural manifestations of, and the strategies for managing, Hunter syndrome (mucopolysaccharidosis (MPS) type II), a rare X-linked lysosomal storage disorder caused by a deficiency of the enzyme iduronate-2-sulphatase. Hunter syndrome is generally considered to have two manifestations: an attenuated form and a severe form; in the latter, the person has pronounced cognitive decline. Infants with either phenotype usually appear normal at birth, but may show some somatic signs. Children with the severe phenotype show developmental delay and changes in behaviour patterns at about 18 months to 4 years of age. To varying degrees, patients with the severe form manifest behavioural disorders such as hyperactivity, aggression, impulsivity, anxiety and sleep disturbances. Medications, such as antipsychotics, benzodiazepines and anticonvulsants, have been tried with varying degrees of success. Behavioural management strategies may be a worthwhile approach, although published data are lacking. For sleep disturbances, behavioural modification plus melatonin or benzodiazepine may be effective treatments.

The Mandorla and the Discipline of Authentic Movement
Authors: Adler Janet
Published: January 2016

Created by two separate circles joining by overlapping each other, forming the shape of an eye, the mandorla is remarkably evident in the imagery of various mystical traditions. Looking into the mandorla is one way of perceiving the wholeness of embodied witness consciousness, which can be understood as the development of the inner witness, the heart, the innermost gem of the Discipline of Authentic Movement. Such a journey begins with the mover in the presence of an outer witness and strengthens, clarifies, becomes compassion within the evolving roles of a moving witness, a silent witness, a speaking witness, an integral witness and an empty mover – empty witness. In the drawings in this essay, it can be seen how the seed of witness consciousness ripens as the commitment to enter each role matures, growing the mandorla larger and larger until it disappears into only one bright and clear empty circle. This non-linear progression can be understood through the inner journey of a mover becoming conscious, becoming whole and simultaneously through the journey of the mover and the outer witness, their relationship becoming conscious, becoming whole.
CALCULATION OF STRESS AND DEFORMATION IN FUEL ROD CLADDING DURING PELLET-CLADDING INTERACTION
Authors: Halabuk Dávid , Martinec Jiří
Published: January 2016

The elementary parts of every fuel assembly, and thus of the reactor core, are fuel rods. The main function of cladding is hermetic separation of nuclear fuel from coolant. The fuel rod works in very specific and difficult conditions, so there are high requirements on its reliability and safety. During irradiation of fuel rods, a state may occur when fuel pellet and cladding interact. This state is followed by changes of stress and deformations in the fuel cladding. The article is focused on stress and deformation analysis of fuel cladding, where two fuels are compared: a fresh one and a spent one, which is in contact with cladding. The calculations are done for 4 different shapes of fuel pellets. It is possible to evaluate which shape of fuel pellet is the most appropriate in consideration of stress and deformation forming in fuel cladding, axial dilatation of fuel, and radial temperature distribution in the fuel rod, based on the obtained results.

Published: January 2016

Existem poucas informações publicadas sobre o efeito da época de colheita no teor de sólidos solúveis - SS (°Brix) de frutos de minitomate. Diante disso, o objetivo do trabalho foi comparar o teor de sólidos solúveis de híbridos de minitomate, portadores do hábito de crescimento determinado versus indeterminado em função da época de colheita. O experimento foi realizado em estufa agrícola, com seis tratamentos: Mascot (hábito de crescimento indeterminado), TSV918 (hábito de crescimento indeterminado), TSV912 (hábito de crescimento indeterminado), TSV678 (hábito de crescimento indeterminado), TSV1278 (hábito de crescimento determinado), TSV910 (hábito de crescimento determinado).  Foram realizadas três colheitas em época distintas (90, 120 e 150 dias após o semeio - DAS) formando um fatorial 6 x 3. Durante as duas primeiras épocas de colheita (90 e 120 DAS) obteve-se os melhores teores de SS. Houve diferença significativa para os frutos coletados no ciclo final das plantas (150 DAS).  O teor de sólidos solúveis variou durante as colheitas (90, 120 e 150 DAS), sendo inferior na última colheita (150 DAS). O hábito de crescimento influenciou o teor de SS apenas no início da colheita (90 DAS).

Authors: Stankiewicz Barbara , Zieliński Krzysztof , Darowski Marek , Michnikowski Marcin
Published: January 2016

Respiratory disturbances frequently accompany stuttering. Their influence on lung ventilation can be assessed by measurement of the end-tidal CO2 concentration (EtCO2). The effectiveness of the CO2-based visual feedback method of breath regulation (VF) designed for stuttering therapy was tested in this study. The aim of the study was to answer the question if the VF helps to reduce respiratory disturbances in stuttering and increase speech fluency. 20 stuttering volunteers aged 13-45 years took part in the 3-parts test consisting of: 1. speaking without any techniques improving speech fluency, 2. learning the VF method, 3. VF-assisted speaking. The CO2/time signal and an acoustic signal of an utterance were recorded during the test. Significant increase of FE - the factor of breath ergonomics during speaking (based on both signals), from 47% to 71% (P < 0.01), and significant decrease of %SS - the percent of syllables stuttered, from 14% to 10% (P < 0.01) were received for VF-assisted utterances compared to the utterances without VF assistance. The results indicate that the VF can help to eliminate respiratory disturbances in stuttering and increase speech fluency.
Nonlinear Properties of the Gotland Deep – Baltic Sea
Authors: Grelowska Grażyna , Kozaczka Eugeniusz
Published: January 2016

The properties of the nonlinear phenomenon in water, including sea water, have been well known for many decades. The feature of the non homogeneous distribution of the speed of sound along the depth of the sea is very interesting from the physical and technical point of view. It is important especially in the observation of underwater area by means of acoustical method (Grelowska et al., 2013; 2014). The observation of the underwater space has been carried out for more than hundred years. In the second half of the twentieth century we observed very intense trend of development of the measuring methods of underwater sound speed. It was done mainly in the linear sound propagation aspect. At the end of 20th century nonlinear devices were invented. Thus, from this point of view, knowledge on the nonlinear properties of the sea water is the matter of interest. The phenomenon of nonlinear distortion of elastic waves, and the same the efficiency of nonlinear transfer of energy from the primary wave to the higher harmonic components depend on properties of the medium, especially on the material constant known as the nonlinearity parameter B/A. The Baltic Sea is a specific reservoir with untypically low salinity and low depth (Grelowska, 2000). In the paper results of investigation of nonlinear properties of the South and the Central Baltic by means of thermodynamic method are presented.

Simulation and optimization of groundwater exploitation for the water supply of Tarnów agglomeration (southern Poland)
Authors: Treichel Wiktor , Haładus Andrzej , Zdechlik Robert
Published: January 2016

This paper presents the application of the simulation-optimization approach to optimize groundwater intake for the water supply of Tarnów agglomeration (southern Poland). Tarnów agglomeration is supplied with water from extensively exploited surface and groundwater intakes located at the confluence of the rivers Dunajec and Biała. Groundwater intakes capture water from the Quaternary aquifer, which is recharged by rainfall and direct infiltration from the rivers and irrigation ditches. Hydrogeological conditions occurring within the area under consideration were mapped by using a single-layer numerical model in Processing Modflow software. After calibrating the simulation model, a simulation-optimization approach was developed with the aim of aiding the process of searching for the best scheme of exploitation of groundwater intake. The unit response matrix method was used to connect the simulation model with the optimization procedure. In the optimization task the objective functions concerning the total volume of groundwater intake discharge and infiltration amount from the River Dunajec or irrigation ditches were applied. Several constraints concerned both the maximum and minimum capacity of individual wells and the entire intake, as well as desirable or undesirable drawdown values in selected control points and control areas. Finally, twelve variants of optimization tasks, for different boundary conditions and different objective functions, were solved and optimal schemes of well discharge distribution within the intake were calculated. The results of optimization show that, depending on the intended objective and the constraints imposed, the best exploitation scenario under the given conditions may be found.
Numerical modelling in research on geothermal systems
Authors: Dendys Marta , Tomaszewska Barbara , Pająk Leszek
Published: January 2016

Nowadays, numerical modelling is a common tool for supporting the research of geothermal systems. Due to the development of computer sciences and access to software dedicated to numerical modelling of hydrogeological processes this is possible. Research can schematise hydrogeological conditions and simulate the work of geothermal systems and thermal water intakes. Research creates numerical models of geothermal systems at the regional and local scale for simulating work of specific thermal waters for example.

In connection with the economic development of the use of thermal waters in Poland there are many research projects where numerical modelling occurs as a primary tool. This paper provides an overview of research issues where the solution to the problem was found by using computer applications and numerical simulators.
Estimation of the impact of climate change-induced extreme precipitation events on floods
Authors: Hlavčová Kamila , Lapin Milan , Valent Peter , Szolgay Ján , Kohnová Silvia , Rončák Peter
Published: January 2016

In order to estimate possible changes in the flood regime in the mountainous regions of Slovakia, a simple physically-based concept for climate change-induced changes in extreme 5-day precipitation totals is proposed in the paper. It utilizes regionally downscaled scenarios of the long-term monthly means of the air temperature, specific air humidity and precipitation projected for Central Slovakia by two regional (RCM) and two global circulation models (GCM). A simplified physically-based model for the calculation of short-term precipitation totals over the course of changing air temperatures, which is used to drive a conceptual rainfall-runoff model, was proposed. In the paper a case study of this approach in the upper Hron river basin in Central Slovakia is presented. From the 1981–2010 period, 20 events of the basin’s most extreme average of 5-day precipitation totals were selected. Only events with continual precipitation during 5 days were considered. These 5-day precipitation totals were modified according to the RCM and GCM-based scenarios for the future time horizons of 2025, 2050 and 2075. For modelling runoff under changed 5-day precipitation totals, a conceptual rainfall-runoff model developed at the Slovak University of Technology was used. Changes in extreme mean daily discharges due to climate change were compared with the original flood events and discussed.
Inner zone terrain correction calculation using interpolated heights
Authors: Zahorec Pavol
Published: January 2016

The discrepancy between real heights of gravity points and the elevation model has a significant impact on the terrain corrections calculation especially within the inner zone. The concept of interpolated heights of calculation points used instead of measured ones within the specified inner zone can considerably decrease the resulting errors. The choice of appropriate radius of the inner zone for use of interpolated heights is analysed on synthetic topography model as well as real data. The tests with synthetic models showed the appropriate radius of this zone is proportional to the deformation wavelength of the model. Simple statistical analysis of a particular elevation model can give an estimate of the appropriate radius for the calculation using interpolated heights. A concept with interpolated heights in the zone 0–250 m is used in actual practice in Slovakia. The analysis of regional gravity data from the Tatry Mountains test area indicates the searched radius should be about 100 m. Detailed gravity measurements from different areas showed the searched radius does not play so important role but the use of interpolated heights instead of measured ones is still relevant. The more reasonable method instead of using interpolated heights is also presented when calculating the topographic effect.
Facilitated Transport of Propylene Through Composite Polymer-Ionic Liquid Membranes. Mass Transfer Analysis
Authors: Zarca Raúl , Ortiz Alfredo , Gorri Daniel , Ortiz Inmaculada
Published: January 2016

Separation of light gaseous olefins from paraffin’s of the refinery process off-gasses has been traditionally performed by cryogenic distillation, which is a highly capital and energy intensive operation. This handicap creates an incentive for the investigation of alternative olefin/paraffin separation technologies. In this regard, membrane technology supposes a potential solution for process intensification. Previous works of our research group reported the use of facilitated transport composite membranes integrating the use of PVDF-HFP polymer, BMImBF4 ionic liquid and AgBF4 silver salt. In this type of membranes, the silver cations react selectively and reversibly with the olefin, allowing the separation via mobile and fixed carrier mechanisms. Ionic liquids were selected as membrane additives because in addition to their negligible vapor pressure that avoids solvent losses by evaporation, they provide stability to the metallic cation dissolved inside, and modify the structure improving the facilitated transport. This technology offers a commercial attractive separation alternative thanks to their modular form of operation, high values of selectivity and permeability and low operational costs. In the present work, propane/propylene permeation experiments involving the use ionic liquids and different membrane compositions were performed. Moreover, basing on the transport and equilibrium parameters previously obtained, a mathematical model description of the system will be proposed fitting the remaining parameters and allowing the design and optimization of the propane/propylene separation process at industrial levels.
Dzierżoniów Town in the eyes of its residents – a study report
Authors: Raszkowski Andrzej
Published: January 2016

Dzierżoniów’s residents definitely represent one of its most valuable resources. Its development and improvement of the generally approached life quality depends on their involvement in solving social and economic problems, their entrepreneurship and creativity. It should also be emphasized that the vast majority of surveyed residents are in favour of their city development. This phenomenon is based on the principle of mutual dependencies, i.e. the better the city functioning, the better living the conditions provided for its residents. On the other hand, the more active and involved the residents are the more effective is their support for the city development (e.g. by their involvement in NGOs’ activities). The presented article was prepared based on the survey studies ordered by Dzierżoniów’s Town Office and conducted in the period July–August 2013 which covered, among others, the city residents (422 respondents). The research was carried out within the framework of one of the stages in developing Dzierżoniów’s Local Sustainable Development Strategy for the period 2014-2020. The purpose of the study is to discuss and assess the selected functional areas of Dzierżoniów Town (geographic environment, economy, technical infrastructure, social infrastructure, city management) based on its residents’ opinions.
Nrf2 activation in the treatment of neurodegenerative diseases: a focus on its role in mitochondrial bioenergetics and function
Authors: Esteras Noemí , Dinkova-Kostova Albena T. , Abramov Andrey Y.
Published: January 2016

The nuclear factor erythroid-derived 2 (NF-E2)-related factor 2 (Nrf2) is a transcription factor well-known for its function in controlling the basal and inducible expression of a variety of antioxidant and detoxifying enzymes. As part of its cytoprotective activity, increasing evidence supports its role in metabolism and mitochondrial bioenergetics and function. Neurodegenerative diseases are excellent candidates for Nrf2-targeted treatments. Most neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, frontotemporal dementia and Friedreich’s ataxia are characterized by oxidative stress, misfolded protein aggregates, and chronic inflammation, the common targets of Nrf2 therapeutic strategies. Together with them, mitochondrial dysfunction is implicated in the pathogenesis of most neurodegenerative disorders. The recently recognized ability of Nrf2 to regulate intermediary metabolism and mitochondrial function makes Nrf2 activation an attractive and comprehensive strategy for the treatment of neurodegenerative disorders. This review aims to focus on the potential therapeutic role of Nrf2 activation in neurodegeneration, with special emphasis on mitochondrial bioenergetics and function, metabolism and the role of transporters, all of which collectively contribute to the cytoprotective activity of this transcription factor.

Authors: Wang X. , Kong D. , Ma Z. , Zhao R.
Published: January 2016

The effect of edible films based on carrot puree, chitosan, corn starch, gelatin, glycerol and cinnamaldehyde on fresh-cut carrots was studied during storage. Several parameters, such as firmness, colour, weight loss, total carotenoids, total phenols, polyphenol oxidase (PPO) activity and peroxidase (POD) activity in coated carrots were determined at regular intervals and then compared with the uncoated carrots throughout the storage period. Significant and expected changes were observed in all carrot samples that were compared. The coating treatment significantly (P < 0.05) delayed the senescence, reduced the deterioration of exterior quality and retained total carotenoids well compared with control (P < 0.05). In addition, significant inhibition of PPO activity (P < 0.05) and POD activity (P < 0.05) as well as reduced accumulation of polyphenols (P < 0.05) were observed for all coated samples. All of these favourable responses induced by coating treatment on minimally processed fresh-cut carrots showed beneficial physiological effects, which would give some useful references to the fresh-cut fruit and vegetable processing industry and satisfy people’s requirements allowing for extending product shelf life without negatively affecting the sensory quality or acceptability.
The transformative potential of action research and ICT in the Second Language (L2) classroom
Authors: Farren Margaret , Crotty Yvonne , Kilboy Laura
Published: January 2016

This study shows the transformative potential of action research and information and communications technology (ICT) in the second language (L2) classroom. Two enquiries from teacher-researchers are detailed in the article. Their engagement in a collaborative professional development Masters programme was pivotal in designing and implementing ICT creatively in their classroom. Gee (2008) advocates the use of the preferred media of our classroom students in order to address their learning. Prensky (2001) urges us to feel the fear and do it anyway with our digital native classes. A post-primary teacher and a primary teacher show us how they felt the fear, did it and transformed aspects of their own teaching in the process. The Masters programme required the teachers to engage with innovative practices, informed by their own values, and integrate technologies that were new to them into their repertoire of classroom strategies. Peer validation meetings with colleagues enabled meaningful insights to emerge from the research. The teachers improve and transform their second language (L2) practice in collaboration and validation with others.

Error analysis for the operator marching method
applied to range dependent waveguides
Authors: Li Peng , Liu Keying , Zuo Weibing , Zhong Weizhou
Published: January 2016

The relations between stability and accuracy of the operator marching method (OMM)
are usually conflicting in waveguides with strong range dependence. To explain this phenomenon,
this study intends to present an error estimate for the OMM in range dependent waveguides. We utilize “approximation level”
to measure truncation error for a marching method in various range step sizes. Then, the error estimate is developed to analyze
the performances of the OMM. Through an error analysis, we verify the following features of the OMM:
(i) it is valid to apply the OMM in slowly varying waveguides with very large range step sizes;
(ii) the OMM may blow up suddenly when the range dependence is strong and the step size is extremely small in the same time.
We also develop a three-number set to describe the stability and accuracy level of a general marching method for computing
wave propagation in a waveguide. In the end, extensive numerical experiments are implemented to verify the correctness
of the error analysis.
Long-term first line medical treatment in a 4-year-old girl with Xq26.3 microduplication-negative somatotropinoma. Case report and literature review
Authors: Maggioli Chiara , Cambiaso Paola , Ciccone Sara , Colafati Giovanna Stefania , Cappa Marco
Published: January 2016

Growth hormone (GH) secreting adenoma represents a therapeutic challenge in childhood. Because of its rarity no treatment guidelines are available and pediatric management often results from recommendations issued for adults. We report a case of a 4-year-old girl with somatotropinoma successfully treated with only medical treatment. She presented with tall stature and history of growth acceleration. Imaging and laboratory confirmed the diagnosis of GH secreting macroadenoma. She started medical treatment with a somatostatin analogue and a dopamine agonist. During an 8-year follow-up period, a good clinical control of the disease and a shrinkage of the adenoma have been demonstrated. At the last observation she achieved normal near-adult height and pubertal development. According to our experience and limited literature evidences, first line treatment with somatostatin analogues can be attempted in patients with somatotropinoma. This approach seems to be able to control the clinical course of the disease, allowing to postpone transphenoidal surgery to adult age or to avoid it.

Authors: Haber Lesław
Published: January 2016

The purpose of this paper was to present the management system evolution, from functional to process to network management. The network management system requires new organizational solutions associated with the fulfilment of external functions in management, directed at the acquisition of stakeholders from the environment who are treated as relational capital. That also requires new skills and competences in searching for relational capital. Possession of that type of capital indicates the importance of a company on a competitive market. The author pointed out the significance of the mobile network leaders’ personal traits, from the viewpoint of their causative power in searching for relational capital. It was pointed out that not every mobile network leader may possess specific personal capabilities to attain relevant objectives.

Byla provedena citlivostni studie různych parametrů simulace. Nejdůležitějši jsou vlastnosti sitě a použite modely turbulence (uvažovane modely: LES, PANS a RANS). Co se tyka sitě, tak kritickym parametrem je konfigurace v těsne blizkosti stěny - tloušťka a počet vrstev těsně u stěny maji velky vliv na průtok, avšak součinitele přične a tečne rotace na tom teměř nezavisi. Odtud plyne, že tyto parametry sitě lze považovat za ladici parametry CFD modelu. Co se tyka velikosti oka sitě, 2 velikosti byly testovany (0.6 a 0.3 mm). Ukazalo se, že ani jedna z těchto siti neni dostatečně jemna pro korektni aplikaci LES. A tedy PANS funguje spiše jako RANS. Z hlediska modelů turbulence je PANS jevi jako nejlepši možnost, protože kombinuje vyhody jak LES, tak RANS. Obecně je možne konstatovat, že lze dosahnout relativně dobre shody na průtoku, ale součinitele přične a tečne rotace jsou problematicke, neboť byla dosažena pouze kvalitativni shoda.

A Novel Approach to Enhance Performance of Multilayer Coated Carbide Insert in Hard Turning
Authors: Shihab Suha K. , Khan Zahid A. , Siddiquee Arshad Noor , Khan Noor Zaman
Published: January 2016

Flank wear of multilayer coated carbide (TiN/TiCN/Al2O3/TiN) insert in dry hard turning is studied. Machining under wet condition is also performed and flank wear is measured. A novel micro-channel is devised in the insert to deliver the cutting fluid directly at the tool-chip interface. Lower levels of cutting parameters yield the minimum flank wear which is significantly affected by cutting speed and feed rate. In comparison to dry and wet machining, insert with micro-channel reduces the flank wear by 48.87% and 3.04% respectively. The tool with micro-channel provides saving of about 87.5% in the consumption of volume of cutting fluid and energy.

The cyclohexanone based solvents show fast and high extraction of the actinides but a somewhat poor diluent stability in contact with the acidic aqueous phase. FS-13-GANEX display high separation factors between the actinides and lanthanides and a good radiolytic and hydrolytic stability. However, the distribution ratios of the actinides are lower, compared to the cyclohexanone based solvents. The hexanol-GANEX is a cheap solvent system using a rather stable diluent but the actinide extraction is, however, comparatively low.
Morphological classification of conspecific birds from closely situated breeding areas – A case study of the Common Nightingale
Authors: Kováts Dávid , Harnos Andrea
Published: January 2016

In this paper, a complex morphological comparison of four Common Nightingale groups (Luscinia megarhynchos) is demonstrated. In total, 121 territorial nightingales were mist-netted and measured individually on four study areas called ‘Bódva’, ‘Felső-Tisza’, ‘Szatmár-Bereg’ and ‘Bátorliget’ in the North-Eastern part of Hungary in 2006–2013. To distinguish groups by morphology, Classification and Regression Trees (CART), Random Forest (RF) and Linear Discriminant Analysis (LDA) methods were used. Comparison of the four studied Common Nightingale groups shows substantial morphological differences in the length of the second, the third and the fourth primaries (P2, P3, P4), in bill length (BL) and bill width (BW), while other characteristics showed greater similarities. Based on the results of all the applied classification methods, birds originated from Szatmár-Bereg were clearly distinguishable from the others. The differences in morphology can be explained by interspecific competition or phenotypic plasticity resulting from the change of ecological, environmental parameters. Our case study highlights the advantageous differences of the classification methods to distinguish groups with similar morphology and to choose important variables for classification. In conclusion, broad application of the classification methods RF and CART is highly recommended in comparative ecological studies.
Eco-geographical variation in the diet of the Barn Owl (Tyto alba) in mountainous areas of France

Published: January 2016

Because of the worldwide distribution of the Barn Owl (Tyto alba) and the easily way to find its pellets, it is often used to diet studies. To investigate the eco-geographical impact of mountainous areas on its diet, we conducted studies in the Jura, Alpes, Central and Pyrénées mountains and we also did pellet analysis from 8 sites in the Jura mountains. Analysis of the tooth and skull content of pellets allowed us to draw up two types of change in the diet of Tyto alba in correlation with mountain elevation. The first one concerns the Jura, Alpes and Central mountains, where the diversity of the diet declines with the increase in elevation. The second one concerns the Pyrénées mountains, where there is no change in the diversity of the diet, perhaps because of the higher diversity of small mammals caused by mediterranean influence. Thus, it seems that elevation cau ses a decrease in diet diversity of Tyto alba in continental mountains (Jura, Alpes and Central mountains) probably because of more homogeneous landscapes dedicated to grass production. However, in Mediterranean mountains (Pyrénées), a more diversified small mammal guild provides a constant level of diet diversity.

Authors: Hadarics Tibor
Published: January 2016

Two new species appeared in the Hungarian avifauna in 2014: the Spanish Sparrow and the Blyth’s Reed Warbler. One pair of Spanish Sparrow was breeding in Bácsborsód between June 13th and July 31st in the side of a stork nest. The Blyth’s Reed Warbler was trapped and ringed near Tömörd on August 15th. With the observations of these species the number of bird species that have ever been proven to occur in Hungary has risen to 411.
The concentration of heavy metals in soils around the wetlands of the Ina valley near Sławęcin / Koncentracja metali ciężkich w glebach mokradeł doliny Iny koło Sławęcina
Authors: Paprota Dariusz
Published: January 2016

Wetlands around the upper part of the Ina valley are the area of great natural value, free from negative industrial impact. In the possible sources of contamination, we could include herbicides and artificial fertilisers from fields and meadows or municipal waste discharge from a small town Recz and local farms. The soils of wetlands, situated in the left part of the Ina valley near Sławęcin, were studied. Four characteristic profiles were made, from which soil samples were collected for laboratory analysis. In the soil samples, the content of organic matter and reaction in 1 mol KCl·dm-3 were determined, whereas in mineral horizons, granulometric composition and the concentration of total and exchangeable forms of heavy metals (Cd, Pb, Cu, Co, Zn, Fe). As a result of conducted studies, it was found that the soils of wetlands in the Ina valley near Sławęcin, do not exhibit contamination with heavy metals but their greater accumulation was observed in the surface muck layers than in fen peat and lower lying sediments.

Effective tools for evaluation of diversity in the collected gene resources of a given species are multivariate statistical methods. They provide information on phenotypic and genetic variability of collected material. The subjects of this study were nine inbred lines and three F1 generations of winter rye (Secale cereale L.), growing in experimental plots of the Polish Academy of Sciences Botanical Garden, Centre for Biological Diversity Conservation in Powsin. The evaluation was performed over the period of 3 years. Observations were made of the following traits: length of stem, length of spike, number of nodes in spike rachis, number of kernels per spike, weight of kernels per spike, weight of 1000 kernels, length of flag leaf, length of subflag leaf, length of third leaf, width of flag leaf, width of subflag leaf, width of third leaf, area of leaves per stem, number of stems per plant and area of leaves per plant.

On the basis of cluster analysis and principal components analysis, two genetically homogeneous groups were identified. Mean values and standard deviations were calculated for each trait in each group and for all genotypes together. Multivariate distance matrix permitted identification of the most genetically similar and most distant forms.

Published: January 2016

Background: In the physiotherapeutic practice, the need for measurements of e.g. range of motion or strength of the cervical spine muscles results from a variety of degenerative processes in the area of the head, cervical spine and shoulder girdle. In Poland, we designed a measurement stand based on the equipment described in foreign literature. Validation of the measurement stand was performed in order to determine the usefulness of this stand for measurements of maximal strength and muscle torques for the isometric contraction of the cervical spine muscles.

Material/Methods: A group of 13 women was examined to validate the device. The criteria for inclusion into the study group were adult age, no back pain and head pain syndromes. Validation of the equipment consisted in the calculation of the intraclass correlation coefficient (ICC). Three measurements were performed for each movement in three planes: initial measurement (I), second measurement after 15 minutes (II) and the third measurement after a week (III). The ICC coefficient was calculated based on the methodology discussed in the study by Shrout and Fleiss (1979).

Results: The results of the measurements reached the "excellent" level of the ICC coefficient between the first and the second test. In the case of the first and the third tests, the ICC coefficient reached the "good" level for the movements in the sagittal and transverse planes and the "excellent" level for the movements in the frontal plane.

Conclusions: The measurement system used in the measurement stand designed by the authors of the present study can be successfully used for comparative studies of several groups or repeated examinations of the same study group after application of a specific therapeutic procedure.The stand cannot be used for evaluation whether the results obtained are consistent with the standards for specific populations or for comparison with the results obtained from other devices.

Published: January 2016

Background: The main objective of this study was to demonstrate the beneficial effects of rehabilitation on self-sufficiency and recovery to everyday activities in patients after stroke.

Material/Methods: The study group comprised 20 patients (11 women and 9 men), who were randomly allocated into two groups of 10 participants each. The first was the control group whose members underwent a 3-week rehabilitation program used in the Neurological Department of the District Hospital in Zawiercie. The study group received the same rehabilitative program but enriched with selected elements of the Bobath concept. On the first and last days of the study each of the patients was assessed with respect to self-sufficiency in performing daily activities using Functional Measure ”Repty” (FMR - simplified version of Functional Independence Measure), upper extremity proximal motor control (the Frenchay Arm Test - FAT) and lower extremity strength (the Timed Up and Go Test - TUG).

Results: The results revealed that patients with enriched rehabilitative program exhibited improvement in a greater numer of physical functions as assessed by the FMR (improvement by 26.4%) compared to the control participants (14.28%). The Frenchay Arm Test and the Timed Up and Go Test showed improvement in upper extremity control and locomotion in the study and control participants. The mean reduction in TUG time was 2.5 s and 3.4 s in the control and study participants, respectively; the results are statistically significant. A FAT task, ie., lifting a cylinder and replacing it improved by a mean of 2 and 0.5 inches; there were also gains in the performance of other tasks such as drinking water from a glass and combing hair.

Conclusions: The final results revealed an improvement of physical function in all patients. However, rehabilitation program enrichment with selected elements of the Bobath concept helped the patients achieve better functional recovery; a 3-week rehabilitation program more effectively contributed to improving self-sufficiency, locomotion and arm function.
