Effect of chronic wound fluid on fibroblasts
Authors: Phillips T.J. , Al-Amoudi H.O. , Leverkus M. , Park H-Y.
Published: December 2016

This study examines how the microenvironment created by fluid in chronic wounds influences the growth of dermal fibroblasts. Newborn fibroblasts, which are known to grow rapidly, were used as a model system to explore how chronic wound fluid affects the growth of regenerative fibroblasts. Wound fluid was collected from patients with chronic venous leg ulcers (duration longer than two months). The biological properties of this fluid were then further characterised to elucidate its molecular effects on cell growth.

Results indicate that chronic wound fluid dramatically inhibited the growth of newborn dermal fibroblasts. This growth inhibitory effect was variable among donors, reversible and heat-sensitive. The inhibitory effect was due not to cytotoxicity or impaired plating efficiency of these cells, but to specific interference with the cell cycle. Chronic wound fluid arrested newborn fibroblast growth by preventing entry into the S-phase, or DNA synthesis-phase, of the cell cycle.

In contrast to its effects on newborn fibroblasts, chronic wound fluid either stimulated or had a minimal effect on fibroblasts which had been cultured from the edge of chronic venous leg ulcers and healthy tissue on the upper thigh in the same patient. This may partially account for the impaired healing seen in chronic venous leg ulcers.

Compression, ulcer recurrence and compliance
Authors: Jones June
Published: December 2016

Patient non-compliance may be perceived by health-care practitioners as hindering implementation of best practice and contributing to the poor outcome of leg ulcer treatments. Patients, however, may believe that the leg ulcer will not heal and that nothing they do will alter that. They may feel that the treatment will necessitate changes in life-style that will outweigh the benefits to be gained by compliance1.
Autoethnographic analysis of the self through an occupational story of a paramedic
Authors: Furness Susan E , Lehmann Jennifer , Gardner Fiona
Published: December 2016

This article discusses the role that storytelling plays in understanding both the personal and professional self from the perspective of a paramedic. The practice of paramedicine provides individuals with a strong platform upon which storytelling can be built, with narration of work-related stories presenting opportunities for reflection on the interplay between organisational culture and self-identity. Using elements of narrative inquiry, autoethnography and critical reflection, a paramedic story is deconstructed and examined from a number of perspectives. From this narrative exploration, three distinct themes emerged and are subsequently discussed: assumptions and preconceptions, fears and insecurities, and distancing and control. The findings illustrate the benefits of exploring paramedic stories in order to recognise, transform or eliminate unhelpful assumptions relating to paramedic practice, and discover unexplored aspects of the self through analysis of story.

Individuo y Sociedad. La incorporación de lo social al liberalismo
Authors: Lario Ángeles
Published: December 2016

En el cambio de siglo desde el XIX al XX, el Estado liberal se encontró de frente con un problema surgido dentro de él mismo: el conocido como “ascenso de las masas”, la necesidad de una representación y de unas políticas para las que el liberalismo no había nacido. A partir de ahí toda reforma liberal pasó por la observación de una vida social más compleja que el mero individuo y sus derechos. A eso se llamó organicismo, y de él surgieron desde ideas totalitarias hasta ideas sociales que reformaron la propia idea liberal y posibilitó el Estado Social de Derecho.
A Publicidade nos jornais portugueses no final da Monarquia: corporativismo profissional e publicidade perante a liberdade da imprensa
Authors: Higes Manuel Romero
Published: December 2016

Neste artigo analisa-se a repressão contra a imprensa periódica portuguesa (os jornais), na fase final da monarquia, afrente da importância dos anúncios no desenvolvimento dos jornais, cujas receitas de publicidade tornam possível a redução no preço da cópia, e desta maneira facilitavam o acesso da imprensa periódica às classes populares. Este cenário favoreceu que muitos dos novos jornais de circulação surgiram, apesar da perseguição da imprensa livre e que mesmo na primeira década do século XX, quando aconteceu o final da Monarquia Portuguesa —e com ela o final da repressão— é quando há uma produção de mais de 3.200 periódicos em Portugal. No entanto, a ascensão dos meios de comunicação social em Portugal, no início do século XX, não pode ser analisada sem ter conta a inserção dos anúncios, que permite a redução dos preços dos jornais e a expansão social a seguir. Além disso, os avanços técnicos na impressão também se refletem na publicidade, os quais são mais atraentes para os anunciantes e os leitores, dando-se nesta fase, uma idade de ouro da publicidade na imprensa, que logra isolar-se da repressão e mesmo desenvolver-se na Primeira República.
Acerca de Silva Dias no seu centenário: evocação em jeito de História e de memória
Authors: Torgal Luís Reis
Published: December 2016

Evocar um autor pode supor uma análise histórica objetiva e um recurso à memória, ou seja, ao testemunho pessoal do autor. Foi isso que se pretendeu fazer, ao escrever este artigo sobre José Sebastião da Silva Dias. Assim, analisou-se Silva Dias como ideólogo, que foi passando de uma perspetiva católica e integralista, com um lastro social, para uma perspetiva socialista democrática. Mas também se tentou mostrar que Silva Dias chegou a essa ideologia, através de uma análise objetiva da História, em que se interligava o conhecimento do documento com a reflexão filosófica. Acima de tudo, como modernista e como contemporaneísta (neste caso mais como orientador de investigação) deve-se-lhe uma «escola» ou «escolas». No fundo renovou a historiografia, lançando as bases, desde os anos de 1960, dos estudos científicos da História Contemporânea.
Morte do rei, incorporação do poder e representação histórica: entre uma poética da ausência e uma poética do saber?
Authors: Marcelino Douglas Attila
Published: December 2016

Este artigo analisa estudos sobre temas como os da morte do rei, das formas de incorporação do poder e dos modos de representação histórica. Eles servem de ponto de partida para uma reflexão sobre a historiografia como forma de discurso caracterizada por certa configuração poética e por seus fundamentos como ritos de recordação. O primeiro aspecto a relaciona a um imaginário político e o segundo a práticas por meio das quais os homens conferem sentido às demandas pelo pertencimento a corpos coletivos imaginários. Apesar do diálogo estabelecido com autores diversos, como Louis Marin, Claude Lefort e Mona Ozouf, tornam-se centrais as interrogações de Jacques Rancière sobre uma «poética do saber» e de Fernando Catroga sobre uma «poética da ausência».
Guardianship and Parental Connections: Connections and Departures in Jeremy Bentham’s Account
Authors: Cox Brian E.
Published: December 2016

This article follows an earlier assessment of Bentham’s views on guardianship
1
that touched on but did not explore connections or departures between guardian-ward and parent-offspring relations, about which Bentham was not as precise as he might have been. Further, he added complexity to the issue by describing parents as occupying dual roles: guardians and ‘masters’ (employers) of their own offspring. These relations are now considered, on the one hand, in the wider context of ‘special relations’ and ‘duties’ and, on the other hand, alongside some appreciation of Bentham’s personal perspectives. However, the main object of the present article is to assess similarities and differences between parents and guardians in legal, status and functional terms. It uses the profile of guardian-ward relations provided by the previous article
2
as a benchmark. The article concludes by affirming that ‘being a parent’ and ‘being a guardian’ have quite different meanings.
Battlefield to Baseball Diamond: The Niagara Parks Commission and Queenston Heights Park
Authors: Young Elaine
Published: December 2016

Between the War of 1812’s end and the late 1920s Queenston Heights was redefined from being primarily a place of memory associated with the War of 1812 to being for the most part a place of recreation. The site of a significant War of 1812 battle, until the late nineteenth century it drew growing numbers of tourists, many of whom wanted to feel closer to its wartime past. Beginning in the late nineteenth century the site’s popularity for recreation increased, and by the 1920s Queenston Heights Park was a destination where thousands of people went to enjoy recreational activities such as picnics and sports. The Niagara Parks Commission, which owned the site from 1895, facilitated this transformation. The Commission saw Queenston Heights more as a park than a historic site and worked to create a recreational space that would draw tourists and increase revenue. By the 1920s the park featured attractions such as playing fields, picnic shelters, tennis courts, a restaurant, and a souvenir stand. There was little opposition to these changes, which at times jeopardized the historic landscape. Although Queenston Heights’ commemorative meanings were no longer closely associated with its battlefield landscape, these meanings were increasingly invested in the imposing Brock Monument. This allowed the Commission’s development of the battlefield to continue unabated, and under the Commission the landscape of the former battlefield became increasingly distanced from its wartime past.
My culture is engraved on my tombstone
Authors: Bada Erdoğan , Ulum Ömer Gökhan
Published: December 2016

We, humans, mirror our cultural characteristics in death just as we do in life. This study focuses on the way the dead communicate with the living through their gravestones. For this, we surveyed, photographed and documented a plethora of gravestones affiliated to Shamanism, Taoism, Judaism, Christianity, and Islam, and conducted content analysis of thematized scripts on stones and objects left on graves for remembrance. Our findings suggest that each set of beliefs displays specific as well as common messages concerning the deceased and the society they belonged to. The study asserts that although we, ephemeral creatures, pass in our final hour, our gravestones keep transmitting our cultural identity from generation to generation with information regarding who and what we were.

Authors: Michalík Martin , Lukeš Vladimír
Published: December 2016

The validation of octanol-water partition coefficients (logP) quantum chemical calculations is presented for 27 alkane alcohols. The chemical accuracy of predicted logP values was estimated for six DFT functionals (B3LYP, PBE0, M06-2X, ωB97X-D, B97-D3, M11) and three implicit solvent models. Triple-zeta basis set 6-311++G(d,p) was employed. The best linear correlation with the experimental logP values was achieved for the B3LYP and B97-D3 functionals combined with the SMD model. On the other hand, no linearity was found when IEF-PCM or C-PCM implicit models were employed.

Authors: Škorňa Peter , Michalík Martin , Klein Erik
Published: December 2016

The DFT study of primary antioxidant action of gallic acid and its carboxylic anion is presented in the gas-phase, benzene and water. Corresponding reaction enthalpies for three possible mechanisms was calculated using B3LYP/6-311++G** method. Bond dissociation enthalpy (BDE) and proton dissociation enthalpy (PDE) of 4-OH group was found to be the lowest in gas-phase as well as in both solvents approximated by IEF-PCM model. Ionization potentials (IPs) were higher than BDEs in all cases. Deprotonation of carboxylic group result in increased antioxidant potency as drop in BDE, proton affinities (PAs) and IPs was indicated in all environments.

Authors: Mikulajová Anna , Šedivá Dominika , Hybenová Eva , Mošovská Silvia
Published: December 2016

Common buckwheat (Fagopyrum esculentum) and tartary buckwheat (Fagopyrum tataricum) cultivars originating in different world countries were investigated and compared for their quantitative and qualitative abundance of phenolics and flavonoids. Moreover, the antioxidant properties were tested using two different methods. The total phenolic and total flavonoid content ranged from 0.897 to 4.226 mg GAE g−1 dw and from 0.238 to 4.626 mg rutin g−1 dw, respectively. Flavonoids — rutin, quercetin, and hydroxybenzoic acids — gallic, protocatechuic, vanillic and syringic were identified and quantified. Rutin was the most abundant flavonoid and protocatechuic acid was the most abundant phenolic acid in evaluated cultivars. All cultivars showed significant antiradical properties, but their chelating activity was weak. The German cultivar of tartary buckwheat Lifago had significantly higher phenolic content and better antioxidant properties than other cultivars. The content of rutin was 24 times higher and free radicals scavenging activity about 70 % higher than the average value of other cultivars.

Published: December 2016

The evaluation of antioxidant potential of food has received much attention in recent years. Antioxidant compounds can scavenge free radicals and thereby can protect the human body from free radicals. This study was focused on the isolation of curcuminoids from the dried turmeric rhizome, and studying their antioxidant activity. The presence of curcuminoids was identified in turmeric sample by Nuclear Magnetic Resonance (NMR) analysis. Since neutral curcumin is known to be poorly soluble, the synthesis of curcumin-cyclodextrin and curcumin-phospholipid complexes was also performed. The antioxidant activity of isolated curcuminoids was assessed by two methods (ABTS and FRAP assay) and their scavenging activities were compared with those of prepared complexes. The ability to reduce ABTS radical cation decreased as follows: quercetin > trolox > curcuminoids > curcumin-cyclodextrin complex > curcumin-phospholipid complex. The reducing potential of tested samples in descending order was quercetin > trolox > curcumin-cyclodextrin complex > curcuminoids > curcumin-phospholipid complex.

Authors: Koziskova Julia , Hahn Friedemann , Richter Jens , Kožíšek Jozef
Published: December 2016

Two different absorption correction methods were compared in order to find out which method is preferable to improve solving and refining a crystal structure. Experiments were performed on the crystal of a tetrakis(μ2-acetato)-diaqua-di-copper(II) complex. The first correction method used was the numerical absorption correction with the aid of a crystal-shape model, and the other was the semi-empirical one, applying scaling routines to the intensity data.

Authors: Kubiňáková Emília , Híveš Ján , Danielik Vladimír
Published: December 2016

Electrical conductivity of NaF-AlF3 melts with an addition of 2 wt % Al2O3 and/or 5 wt % CaF2 was measured using a pyrolytic boron nitride tube-type cell with a constant distance of electrodes. The molar cryolite ratios MR = n(NaF)/n(AlF3) were 1.8 and 1.6, and the temperature was varied from 865 °C to 1005 °C. Ac-techniques with a sine wave signal with small amplitude in the high frequency range were applied. Electrolyte resistance was obtained from nonlinear regression analysis according to equivalent circuit. Experimental data were used to describe the dependence of the electrical conductivity in fluoride melts with lower temperature on the amount of various additions and temperature.

Authors: Cinková Kristína , Andrejčáková Dana , Švorc Ľubomír
Published: December 2016

This paper presents an electrochemical behavior study and quantification of fluoroquinolone antibiotic ciprofloxacin using boron-doped diamond electrode. Ciprofloxacin provides a diffusion-driven electrode reaction with an irreversible and poorly defined peak at +1.6 V vs. Ag/AgCl electrode in the presence of Britton-Robinson buffer solution pH 4. Applying differential pulse voltammetry (modulation amplitude of 60 mV, modulation time of 50 ms), the calibration curve with high linearity (R
2 = 0.997) was obtained within the concentration range of (0.74 – 20.0) × 10−6 mol L−1 with the detection limit of 6.0 × 10−7 mol L−1 and repeatability expressed by relative standard deviation of 2.7 % (for 20 measurements). Interference study was performed to explore the selectivity of the elaborated procedure. By analysis of pharmaceutical dosages and model human urine samples, the ciprofloxacin content with the recovery values ranging from 88.4 to 121.2 % were determined. The developed approach using point-of-care electrochemical sensor based on boron-doped diamond material could represent inexpensive analytical alternative to separation methods and could be beneficial in analysis of biological samples and in the quality control in pharmaceutical industry.
An efficient and accurate method to calculate diffusion coefficient of structured particles. A first case study of Pb diffusion in rare gases
Authors: Matúška Ján
Published: December 2016

Diffusion coefficient depends on temperature, pressure, reduced mass of colliding particles and collision cross section. The presented method is designed to calculate the diffusion coefficient in loose systems containing molecules with relatively complicated colliding trajectories. It is a combination of the Chapman-Enskog theory and the molecular dynamics calculation. The Chapman-Enskog theory provides the relation between the diffusion coefficient and the collision cross section which is the result of multiple integration of the scattering angle of all possible initial conditions of the collision. The scattering angle is obtained by numerical integration of the Newton’s equation of motion with previously selected initial conditions. The proposed method has been verified for the simple system of a lead atom diffusion in rare gases and the results were compared to those of two other theoretical methods.
Effect of light emitting diodes with different color temperatures on immune responses and growth performance of male broiler
Authors: Sharideh Hossein , Zaghari Mojtaba
Published: December 2016

The aim of the present study was to evaluate the effects of the different color temperatures (Kelvin; K) of the light emitting diodes (LEDs) on broiler chicken health and growth performance compared to incandescent (ICD) light bulbs. Three hundred and sixty one-day-old Ross 308 male chicks were tested for 42 days. The chicks were randomly distributed into three treatment groups [neutral-white (4,286 K), warm-white (2,990 K), and ICD (2,790 K) light bulbs] of 120 chicks/treatment with six replicates each by adopting complete randomized design. The diets were similar for all treatment groups. The live body weight and feed intake were recorded weekly and feed conversion ratio (FCR) was calculated (weekly and whole period). Indices of humoral immunity [antisheep red blood cell (SRBC) titer, IgG, and IgM at 26 and 34 days of age], Newcastle disease (ND) virus and avian influenza (AI) virus antibody at 40 days of age, cell-mediated immunity [cutaneous basophilic hyper-sensitivity (CBH) response at 41 days of age)] as well as total and differential leukocyte numbers at 42 days of age) were measured. Effects of different color temperatures of the LEDs and ICD light bulbs on body weight, feed consumption, and FCR were not statistically significant (P>0.05). Also, the effect of color temperatures of light on secondary titers of SRBC, AI antibody response, CBH response, the total number of leukocytes and percentage of lymphocytes were not significant. However, the different color temperatures of LEDs have a significant effect on primary SRBC and ND antibody titers (P≤0.05). The highest primary SRBC (P≤0.05) and ND (P≤0.05) antibody titers were observed in warm-white light. It was concluded that based on the 3 color temperatures examined, it seems that the most suitable to provide the optimum level of immunity and energy-saving in commercial broiler houses is warm-white light.

Authors: Ratkovic Marina , Jukic Nikolina Basic , Radunovic Danilo , Prelevic Vladimir , Gledovic Branka
Published: December 2016

Introduction. There was no transplantation program in Montenegro until 2012. On the other hand, there were 93 patients with transplanted kidney. These transplantations were performed abroad; 15% in areas of black organ markets (India, Pakistan, Russian Federation). Beside the ethical problems, these transplantations carried a high risk of complications.

Methods. Our health system had to ensure solution for patients with terminal organ failure. Preparation of all neccessary conditions for the beginning of transplantation program in Montenegro started in 2006 with different activities including public, legal, medical, educational and international cooperation aspects.

Results. The first kidney transplantation from living donor in Montenegro was preformed on September 25th, 2012. In the period from 2012 until now 23 kidney transplantations from living related donor were performed and one kidney transplantation from deceased donor in the Clinical Center of Montenegro. In the a two year-follow-up period, all patients to whom kidney transplantation was performed are in a good condition and without serious complications in posttransplant period.

Conclusion. Development of the transplantation program allowed controlled transplantation and safety of patients. Our next steps are development of deceased organ donor transplantation and achievement of higher rate of deceased donor organ transplantation and individualization of immunosuppressive therapy.

Published: December 2016

Introduction.Cardiovascular diseases are the leading cause of death in hemodialysis patients. The decline of residual renal function increases the prevalence and severity of risk factors of cardiovascular morbidity and mortality in these patients. Hypertension is common in dialysis patients and represents an important independent factor of survival in these patients.

Methods.The study included 77 patients who are on chronic HD for longer than 3 months. Depending on the measured residual diuresis patients were divided into two groups. The study group consisted of patients with residual diuresis >250 ml/day, while patients from control group had residual diuresis <250 ml/day. All patients had their blood pressure measured before 10 consecutive hemodialysis treatments. Collected data were statistically analyzed using SPSS 16.0.

Results.The study included 77 hemodialysis patients, mean age of 56.56±14.6 years and mean duration of hemodialysis treatment of 24.0 months. Of the total number of patients, 39(50.6%) had preserved residual renal function. Hypertension was more common in the group of patients who did not have preserved residual renal function (68.4% vs 25.6%). There was statistically significant negative linear correlation between the volume of residual urine output and the residual clearance of urea and values of systolic blood pressure [(rho=−0.388; p<0.0001); (rho=−0.392; p<0.0005)], values of mean arterial pressure [(rho =−0.272; p<0.05); (rho=−0.261; p=0.023; p<0.05)] and values of pulse pressure in hemodialysis patients [(rho =−0.387; p<0.001); (rho=−0.400; p<0.0005)].

Conclusions.Residual renal function plays an important role in controlling blood pressure in patients on hemodialysis. More attention should be directed to preserve residual renal function, and after the start of hemodialysis by avoiding intensive ultrafiltration with optimal antihypertensive therapy.

Laboratory Measurements of Particulate Matter Concentrations from Asphalt Pavement Abrasion
Authors: Fullová Daša , Đurčanská Daniela
Published: December 2016

The issue of emissions from road traffic is compounded by the fact that the number of vehicles and driven kilometres increase each year. Road traffic is one of the main sources of particulate matter and traffic volume is still increasing and has unpleasant impact on longevity of the pavements and the environment. Vehicle motions cause mechanical wearing of the asphalt pavement surface - wearing course by vehicle tyres. The contribution deals with abrasion of bituminous wearing courses of pavements. The asphalt mixtures of wearing courses are compared in terms of mechanically separated particulate matter. The samples of asphalt mixtures were rutted in wheel tracking machine. The particulate matter measurements were performed in laboratory conditions. The experimental laboratory measurements make it possible to sample particulates without contamination from exhaust emissions, abraded particles from vehicles, resuspension of road dust and climate affects. The contribution offers partial results of measurements on six trial samples of asphalt mixtures with different composition. It presents particulate matter morphology and the comparison of rutted asphalt samples in terms of PM mass concentrations and chemical composition.

Sympathectomized tumor-bearing mice survive longer but develop bigger melanomas
Authors: Horvathova L , Tillinger A , Padova A , Mravec B
Published: December 2016

Objectives.Previously we have shown that 20 days after the tumor cells injection smaller melanomas have been developed in chemically sympathectomized mice in comparison with animals having intact sympathetic nervous system. However, it is known that chemical sympathectomy reduces the sympathetic neurotransmission only temporarily. In the present study, we monitored the survival of the sympathectomized mice with melanoma with an attempt to find out how long the suppressing effect of sympathectomy on the melanoma growth may endure.

Methods.The chemical sympathectomy was performed by intraperitoneal injection of neurotoxin 6-hydroxydopamine in male C57BL/6J mice. Seven days later, the animals were injected subcutaneously with B16-F10 melanoma cells. Then, melanoma development, survival of the tumor-bearing mice and weight of the developed tumor mass were analyzed.

Results.Sympathectomy delayed the development of the palpable tumors (18th day vs.14th day) and significantly prolonged the survival of the tumor-bearing mice (median 34 days vs. 29 days). However, the weight of the developed melanoma was significantly increased in the sympathectomized mice in comparison with the animals having intact sympathetic nervous system.

Conclusions.The data of the present study showed that effect of the chemical sympathectomy, performed before the tumor growth induction, persisted even at the time when sympathetic nerves started to regenerate that resulted in a prolonged survival of the mice with melanoma. However, comparing to our previous study, in which we have shown a reduced tumor mass in earlier stages of the tumor growth, specifically 20 days after melanoma cells injection, now we indicate that in later stages of the melanoma progression, the tumor mass was significantly increased in sympathectomized animals. These contra-intuitive findings may indicate that interventions affecting the sympathetic nervous system may exert complex effect on the tumor progression. Based on these data we may suggest that the potential therapeutic interventions affecting the sympathetic signaling in the tumor tissue and its microenvironment should attenuate the sympathetic neurotransmission not only temporarily but till the complete regression of the tumor tissue.
A case of hypercalcaemic crisis secondary to coexistence of primary hyperparathyroidism and Graves’ disease

Published: December 2016

A 46 year-old female patient presented to the hospital with ongoing and progressively increasing fatigue, severe nausea and vomiting, loss of appetite, constipation, palpitations and somnolence. Laboratory evaluation revealed a severe hypercalcaemia and overt hyperthyroidism. She was diagnosed with primary hyperparathyroidism accompanied by Graves’ disease. The patient underwent total thyroidectomy and right inferior parathyroid gland adenoma excision on the 24th day of her admission to the hospital after calcium levels and free thyroid hormone levels were brought to normal ranges. We suggest that a possibility of simultaneous thyrotoxicosis and primary hyperparathyroidism in cases presenting with a hypercalcaemic crisis should be considered
The law-making activity of the administrative courts in tax matters
Authors: Mach Joanna
Published: December 2016

The aim of this article is to highlight that the actual role of the administrative courts in tax matters is not only applying law, in the classical meaning, but also making law. In fact, those two terms: making law and applying law are difficult to distinguish. The question is, to what extent the administrative courts should participate in law making. The fact is, that in numerous cases judgements protect taxpayers from negative effects of tax regulations.

Certain ways of detecting the initial stages of damage have been demonstrated to trees oak, larch and spruce. The initial stages of damage by molds at non-durable maple, alder and poplar had not a clear impact on the decrease in the speed of ultrasonic, as well as hairline surface cracks at the Douglas fir.
Effects of Northern red oak (Quercus rubra L.) and sessile oak (Quercus petraea (Mattusch.) Liebl.) on the forest soil chemical properties
Authors: Miltner Stanislav , Kupka Ivo , Třeštík Michal
Published: December 2016

Northern red oak (Quercus rubraL.) is one of the most important introduced tree species in the Czech Republic, occupying about 6,000 ha with ca. 900,000 m3of the standing volume. The presented study aims to evaluate its soil forming effects on natural oak sites. Soil chemistry of the upper soil layers (F+H, Ah, B horizons) was studied in three pairs of stands of both species. In each stand, four bulk samples were taken separately for particular horizons, each consisting of 5 soil-borer cores. The soil characteristics analysed were: pH (active and potential), soil adsorption complex characteristics (content of bases, exchangeable cation capacity, base saturation), exchangeable acidity (exchangeable Al and H), total carbon and nitrogen content, and plant available nutrients content (P, K, Ca, Mg). Total macronutrient content (P, K, Ca, Mg) was analysed only in holorganic horizons. Results confirmed acidification effects of red oak on the upper forest soil layers such as decreased pH, base content, base saturation, all nutrient contents in total as well as plant-available form and increased soil exchangeable acidity (exchangeable Al) in comparison to the sessile oak stands, especially in holorganic horizons and in the uppermost mineral layer (Ahhorizon). Northern red oak can be considered as a slightly site-soil degrading species in the studied sites and environmental conditions in comparison to native oak species.

Authors: Minďaš Jozef , Škvareninová Jana
Published: December 2016

Study of the effects of climate change on upper tree limit has mainly focused on the diversity of tree species as a result of the ability of species to tolerate temperature and moisture changes as well as some effects of disturbance regime changes. The tree species diversity changes due to climate change has been analysed via gap model and biodiversity indices. Gap models are individually based on simulations of establishment, growth, and mortality of each tree on the forest plot. Input ecological data for model calculations have been taken from the permanent research plots located in primeval forests in mountainous regions in Slovakia. The results of regional scenarios of the climatic change for the territory of Slovakia have been used, from which the values according to the CGCM3.1 (global) model, KNMI and MPI (regional) models. Model results for conditions of the climate change scenarios suggest a shift of the upper forest limit to the region of the present subalpine zone, in supramontane zone. The most significant tree species diversity changes have been identified for the upper tree line and current belt of dwarf pine (Pinus mugo) occurrence. Hill’s index of biodiversity in the upper forest line increased by 30 – 35% for horizon of 2050, resp. by 45 – 50% modeled for the horizon of 2075. Calculated values of Shannon’s index show an even higher increase due to climate change. For horizon 2050 is a roughly of three fold increase and horizon for 2075 by almost fivefold increase in the value of the index. Results from the gap model indicate the increase of tree species diversity 2 – 2,5 times.
Cousin’s Lemma
Authors: Coghetto Roland
Published: December 2016

We formalize, in two different ways, that “the n-dimensional Euclidean metric space is a complete metric space” (version 1. with the results obtained in [13], [26], [25] and version 2., the results obtained in [13], [14], (registrations) [24]).

With the Cantor’s theorem - in complete metric space (proof by Karol Pąk in [22]), we formalize “The Nested Intervals Theorem in 1-dimensional Euclidean metric space”.

Pierre Cousin’s proof in 1892 [18] the lemma, published in 1895 [9] states that:

“Soit, sur le plan YOX, une aire connexe S limitée par un contour fermé simple ou complexe; on suppose qu’à chaque point de S ou de son périmètre correspond un cercle, de rayon non nul, ayant ce point pour centre : il est alors toujours possible de subdiviser S en régions, en nombre fini et assez petites pour que chacune d’elles soit complétement intérieure au cercle correspondant à un point convenablement choisi dans S ou sur son périmètre.”

(In the plane YOX let S be a connected area bounded by a closed contour, simple or complex; one supposes that at each point of S or its perimeter there is a circle, of non-zero radius, having this point as its centre; it is then always possible to subdivide S into regions, finite in number and sufficiently small for each one of them to be entirely inside a circle corresponding to a suitably chosen point in S or on its perimeter) [23].

Cousin’s Lemma, used in Henstock and Kurzweil integral [29] (generalized Riemann integral), state that: “for any gauge δ, there exists at least one δ-fine tagged partition”. In the last section, we formalize this theorem. We use the suggestions given to the Cousin’s Theorem p.11 in [5] and with notations: [4], [29], [19], [28] and [12].
Binary Relations-based Rough Sets – an Automated Approach
Authors: Grabowski Adam
Published: December 2016

Rough sets, developed by Zdzisław Pawlak [12], are an important tool to describe the state of incomplete or partially unknown information. In this article, which is essentially the continuation of [8], we try to give the characterization of approximation operators in terms of ordinary properties of underlying relations (some of them, as serial and mediate relations, were not available in the Mizar Mathematical Library [11]). Here we drop the classical equivalence- and tolerance-based models of rough sets trying to formalize some parts of [18].

The main aim of this Mizar article is to provide a formal counterpart for the rest of the paper of William Zhu [18]. In order to do this, we recall also Theorem 3 from Y.Y. Yao’s paper [17]. The first part of our formalization (covering first seven pages) is contained in [8]. Now we start from page 5003, sec. 3.4. [18]. We formalized almost all numbered items (definitions, propositions, theorems, and corollaries), with the exception of Proposition 7, where we stated our theorem only in terms of singletons. We provided more thorough discussion of the property positive alliance and its connection with seriality and reflexivity (and also transitivity). Examples were not covered as a rule as we tried to construct a more general mechanism of finding appropriate models for approximation spaces in Mizar providing more automatization than it is now [10].

Of course, we can see some more general applications of some registrations of clusters, essentially not dealing with the notion of an approximation: the notions of an alliance binary relation were not defined in the Mizar Mathematical Library before, and we should think about other properties which are also absent but needed in the context of rough approximations [9], [5]. Via theory merging, using mechanisms described in [6] and [7], such elementary constructions can be extended to other frameworks.
Tarski Geometry Axioms – Part II
Authors: Coghetto Roland , Grabowski Adam
Published: December 2016

In our earlier article [12], the first part of axioms of geometry proposed by Alfred Tarski [14] was formally introduced by means of Mizar proof assistant [9]. We defined a structure TarskiPlane with the following predicates:

of betweenness between (a ternary relation),

of congruence of segments equiv (quarternary relation),

which satisfy the following properties:

congruence symmetry (A1),

congruence equivalence relation (A2),

congruence identity (A3),

segment construction (A4),

SAS (A5),

betweenness identity (A6),

Pasch (A7).

Also a simple model, which satisfies these axioms, was previously constructed, and described in [6]. In this paper, we deal with four remaining axioms, namely:

the lower dimension axiom (A8),

the upper dimension axiom (A9),

the Euclid axiom (A10),

the continuity axiom (A11).

They were introduced in the form of Mizar attributes. Additionally, the relation of congruence of triangles cong is introduced via congruence of sides (SSS).

In order to show that the structure which satisfies all eleven Tarski’s axioms really exists, we provided a proof of the registration of a cluster that the Euclidean plane, or rather a natural [5] extension of ordinary metric structure Euclid 2 satisfies all these attributes.

Although the tradition of the mechanization of Tarski’s geometry in Mizar is not as long as in Coq [11], first approaches to this topic were done in Mizar in 1990 [16] (even if this article started formal Hilbert axiomatization of geometry, and parallel development was rather unlikely at that time [8]). Connection with another proof assistant should be mentioned – we had some doubts about the proof of the Euclid’s axiom and inspection of the proof taken from Archive of Formal Proofs of Isabelle [10] clarified things a bit. Our development allows for the future faithful mechanization of [13] and opens the possibility of automatically generated Prover9 proofs which was useful in the case of lattice theory [7].
Diagnostic sources of information on sports result determinants in young powerlifting athletes
Authors: Ryguła Igor , Płóciennik Łukasz , Lipińska Patrycja
Published: December 2016

Purpose

Sports results in powerlifting have been extensively studied, but there is no analysis of the diagnostic sources of criteria for selecting 19–20-year-old athletes. Therefore, it is important to continue the study of factors affecting performance in powerlifting, not only in individual events, but also in the entire discipline. There were two research objectives in the study: firstly, to identify a set of independent (predictor) variables contributing to sports results (outcome variable) in powerlifting using the least numbers of those variables, and secondly, to develop a biometric regression model describing the sports result.

Methods

The study group (n = 30) comprised juniors (aged 19.4 ± 0.7) training powerlifting. The following methods of collecting information were used: observation, survey, and analytical methods of diagnostics: analysis of multiple regression functions, and selection of optimal variables with the use of Hellwig’s algorithm.

Results

The optimal set of variables predicting sports results in junior powerlifting consists of nine features. The integral capacity of the selected information sources reached the value of 0.891.

Conclusions

It was confirmed that body composition, special physical fitness, and the technique of movement would constitute the optimum combination of explanatory variables of the model. These characteristics have the highest value as diagnostic and selection criteria and should not be overlooked.
Stability Analysis and Internal Heating Effect on Oscillatory Convection in a Viscoelastic Fluid Saturated Porous Medium Under Gravity Modulation
Authors: Bhadauria B.S. , Singh M.K. , Singh A. , Singh B.K. , Kiran P.
Published: December 2016

In this paper, we investigate the combined effect of internal heating and time periodic gravity modulation in a viscoelastic fluid saturated porous medium by reducing the problem into a complex non-autonomous Ginzgburg-Landau equation. Weak nonlinear stability analysis has been performed by using power series expansion in terms of the amplitude of gravity modulation, which is assumed to be small. The Nusselt number is obtained in terms of the amplitude for oscillatory mode of convection. The influence of viscoelastic parameters on heat transfer has been discussed. Gravity modulation is found to have a destabilizing effect at low frequencies and a stabilizing effect at high frequencies. Finally, it is found that overstability advances the onset of convection, more with internal heating. The conditions for which the complex Ginzgburg-Landau equation undergoes Hopf bifurcation and the amplitude equation undergoes supercritical pitchfork bifurcation are studied.
Similarity Solution for Combined Free-Forced Convection Past a Vertical Porous Plate in a Porous Medium with a Convective Surface Boundary Condition
Authors: Garg P. , Purohit G.N. , Chaudhary R.C.
Published: December 2016

This paper studies the mathematical implications of the two dimensional viscous steady laminar combined free-forced convective flow of an incompressible fluid over a semi infinite fixed vertical porous plate embedded in a porous medium. It is assumed that the left surface of the plate is heated by convection from a hot fluid which is at a temperature higher than the temperature of the fluid on the right surface of the vertical plate. To achieve numerical consistency for the problem under consideration, the governing non linear partial differential equations are first transformed into a system of ordinary differential equations using a similarity variable and then solved numerically under conditions admitting similarity solutions. The effects of the physical parameters of both the incompressible fluid and the vertical plate on the dimensionless velocity and temperature profiles are studied and analysed and the results are depicted both graphically and in a tabular form. Finally, algebraic expressions and the numerical values are obtained for the local skin-friction coefficient and the local Nusselt number.
