Foucault with radio anyone?
Authors: Aroney Eurydice , Olsson Michael
Published: October 2015

This article presents a case study of a compulsory first-year undergraduate communication degree subject (Language and Discourse) that combines critical discourse analysis, genre and multimodality studies with the teaching of radio production. Using audio/radio as its primary focus, the subject is delivered to over 700 students per semester and aims to produce communications professionals whose everyday practice is informed by an understanding of how theory and practice work together. Described here are the rationale, pedagogical approach and early outcomes of this subject through qualitative research methods including interviews with key course designers, tutors and students. In this subject students produce genre-diverse radio/audio pieces that reflect an understanding of complex theoretical concepts, such as Foucault’s work on discourse analysis. The article concludes that radio has a distinctive part to play in the teaching of language and media studies to large cohorts of students using the skills and resources brought to the subject by a generation of digital natives.
The Portuguese free radio movement in the Southern European context1,2
Authors: Santos Susana
Published: October 2015

The main objective of this article is to provide an understanding of the Portuguese free radio movement while at the same time presenting it as a part of the Southern European movement. Theoretically, we use the concept of media system provided by Hallin and Mancini – in particular, the polarized pluralist model used to describe the Mediterranean countries. The Portuguese movement shared with its Greek counterpart some of the characteristics associated with the sharing and enjoyment of music. Comparison with the French free radio movement allows us to frame the reaction of the Portuguese party political system to the illegal broadcasting phenomenon. The methodological strategy is based on the triangulation of information sources. A total of fifteen in-depth interviews were conducted with free radio activists, parliamentarians and journalists, and press reports and parliamentary debates between 1983 and 1988 were subjected to content analysis. With the study of the recent past we want to contribute towards the public debate about mass media in subjects like regulation and the state, pluralism and public service, media economic groups, freedom of information and expression, and citizenship rights.
Radio and secondary orality: A rhetorical analysis of the Colombian radio programme Hora 20
Authors: Angel Adriana
Published: October 2015

Despite its high levels of consumption, there is little research about the grammar, communicative genres and codes through which radio is produced. This article strives to fulfill this gap in the literature and provides some preliminary ideas and exploratory characteristics about the language of radio. After conducting a rhetorical analysis of the talk radio programme Hora 20, broadcast by a highly consumed Colombian radio station, this article suggests a few levels that allow us to start thinking about the grammar of radio. Specifically, this article suggests three main levels through which the secondary orality of radio manifests in Hora 20: empathetic, grammatical and dialogic levels. It examines how the use of elements, such as interjections, rhythm, tone, flow, spontaneity, genre, enumeration, redundancy, as well as parallel, pedagogical, collaborative and confrontational dialogues, define the language of talk radio. Finally, this piece claims that all three levels and corresponding sub-levels of secondary orality create a particular rhetorical situation of addressivity in which speakers connect with their addressees in particular ways.

La crítica literaria en las revistas del fin de siglo como fuente historiográfica
Authors: Celma Valero María Pilar
Published: October 2015

Se hace un repaso de la crítica literaria inserta en las revistas del Fin de siglo, que adquiere una importancia inusitada en el momento, así como de las distintas modalidades críticas, para valorar su potencial utilización como fuente historiográfica en la reconstrucción de este controvertido periodo de la literatura hispánica. Los artículos de crítica objetiva resultan más útiles para apreciar la recepción de autores y obras. Los artículos de crítica subjetiva, impresionista, permiten conocer la concepción estética tanto del autor reseñado como del crítico.
Primeros datos sobre la presencia del reportero en la prensa española
Authors: Ezama Gil Ángeles
Published: October 2015

Desde su aparición en la prensa en torno a los años 70 del siglo XIX, el reporter goza de una notoria impopularidad, desempeñando inicialmente una mera función de informador o noticiero, poco valorada y subordinada a la tarea del cronista o del articulista. Los conflictos bélicos del siglo XIX sitúan su figura en un primer plano y van confiriendo independencia y estima a un oficio que antes no las tenía, tanto en el ámbito del relato de hechos como en el aspecto gráfico. La aparición de las agencias de noticias probablemente influyera en este desplazamiento, ya que al hacerse estas cargo de vender la información a los periódicos, el oficio de reporter se hace menos necesario en este sentido. Así, el trabajo del reporter se reformula, convirtiéndose entonces, como señalaba Sánchez Pérez, en el profesional que da forma a las noticias, las redacta o las inventa.

Rescatar del olvido (Azorín en Blanco y Negro)
Authors: Vidal Ortuño José Manuel
Published: October 2015

Atendiendo a las exigencias de este monográfico, se estudian algunos artículos que José Martínez Ruiz escribió para el semanario gráfico Blanco y Negro entre 1904 y 1910. Son, precisamente, aquellos que, en 1963, José García Mercadal recogió en el volumen titulado En lontananza, entre otros tantos de diversa procedencia. Estas colaboraciones fueron una especie de taller literario para Azorín, puesto que las que no pasaron a un libro sirvieron como probaturas para obras o partes de obras posteriores. Otras veces, en cambio, nuestro autor reelaboró escritos ya existentes, dándoles una nueva dimensión. Por último, en las páginas de Blanco y Negro quedaron olvidados bellos cuentos que luego no encontraron cabida en ningún volumen de la amplia creación azoriniana.
The Influence Of Loam Type And Cement Content On The Compressive Strength Of Rammed Earth
Authors: Narloch P. L. , Woyciechowski P. , Jęda P.
Published: October 2015

Currently, a worldwide dynamic rise of interest in using soil as a construction material can be observed. This trend is evident in the rapid rise of the amount of standards that deal with soil techniques. In 2012 the number of standards was larger by one third than five years prior. To create a full standardization of the rammed earth technique it is necessary to take into account the diversity of used soil and stabilizing additives. The proportion of the components, the process of element production and the research methods must also be made uniform. The article describes the results of research on the compressive strength of rammed earth samples that differed from each other with regards to the type of loam used for the mixture and the amount of the stabilizer. The stabilizer used was Portland cement CEM I 42.5R. The research and the analysis of the results were based on foreign publications, the New Zealand standard NZS 4298:1998, the American Standard NMAC14.7.4 and archival Polish Standards from the 1960’s that dealt with earth material.

Models For Determining Annual Average Daily Traffic On The National Roads
Authors: Spławińska M.
Published: October 2015

One of the basic parameters which describes road traffic is Annual Average Daily Traffic (AADT). Its accurate determination is possible only on the basis of data from the continuous measurement of traffic. However, such data for most road sections is unavailable, so AADT must be determined on the basis of short periods of random measurements. This article presents different methods of estimating AADT on the basis of daily traffic (VOL), and includes the traditional Factor Approach, developed Regression Models and Artificial Neural Network models. As explanatory variables, quantitative variables (VOL and the share of heavy vehicles) as well as qualitative variables (day of the week, month, level of AADT, the cross-section, road class, nature of the area, spatial linking, region of Poland and the nature of traffic patterns) were used. Based on comparisons of the presented methods, the Factor Approach was identified as the most useful.
Endocrine And Metabolic Adaptations Of Calves To Extra-Uterine Life
Authors: Danijela Kirovski
Published: October 2015

The transition from intra- to extra-uterine life is one of the greatest physiological challenges that occur in the life of animals. Immediately after birth, newborn calves have to adapt to new environmental and feeding conditions. Namely, at birth a break of the thermal balance occurs, since calves abruptly pass from a 38.8°C temperature in utero to an environmental temperature that is generally lower than 20°C. Additionally, at birth, the energy intake shifts from a continuous parenteral supply of nutrients (mainly glucose) to discontinuous colostrum and milk intake with lactose and fat as the main energy sources. Therefore, the most important issues related to metabolic changes during the transition from intra- to extra-uterine life are related to maintaining the homoeothermic conditions and control of energy metabolism. Those metabolic adaptations are under control of the endocrine system that is relatively mature at birth, but still requires morphological and functional changes after birth. Key hormones whose concentrations are significantly changed around birth and are involved in an adequate adaptation of calves to extra-uterine life are those related to stress at birth (cortisol and cathecholamines), glucoregulatory processes (insulin and glucagon), thermogenesis (thyroid hormones) and growth (IGF axis).

Published: October 2015

The aim of this study was to investigate the etiology of subclinical mastitis (SCM) in dairy Jersey cows with the use of bacteriological and molecular identification methods. In the study 121 Jersey and 78 hybrid Jersey cows with SCM were observed in the Samsun district of Turkey. A total of 411 California mastitis test (CMT) positive milk samples from these animals were examined bacteriologically. The prevalence of subclinical mastitis was 54.75% and 67.2% in Jerseys and hybrids, respectively. On bacteriological examination, a total of 92 strains were isolated from 411 milk samples. The most prevalent bacteria were Staphylococcus spp. (69.56%). Among them 24 isolates were Staphylococcus aureus (26.08%) the other isolates were Streptococcus dysgalactiae (23.91%), Enterococcus spp. (3.26%) and Streptococcus agalactiae (3.26%). All strains were identified with bacteriological culture methods, as well as by Polymerase Chain Reaction (PCR). Gram-negative bacteria were not isolated. In conclusion, the etiology of SCM in full blood and hybrid Jersey dairy cows in Samsun and the prevalence of bacteria were determined. The relatively high prevalence of SCM indicates the potential need for the consideration of some factors contributing to the formation of mastitis (e.g. management) as well as bacterial agents. The present study and further studies may be useful to develop mastitis vaccines by means of providing true vaccine strain sources.

Published: October 2015

Salmonella enterica serotype Enteritidis is an important alimentary pathogen that recently gained special attention due to the ability of a large number of strains to form biofilms. Qualitative testing of biofilm forming ability was performed by observing the morphotype of the colonies on Congo Red agar and by conducting the pellicle test, while quantitative testing was carried out by Cristal violet assay on microtiter plates. A total of 14 isolates of S. Enteritidis were tested for biofilm forming ability, while Salmonella Enteritidis ATTC 13076 was used as the reference strain. Based on the morphotype of colonies cultivated on Congo Red agar at 25°C incubation temperature, among tested isolates three morphotypes were detected – red, dry and rough (rdar), brown, dry and rough (bdar) and smooth and white (saw). Half of the tested isolates demonstrated rdar morphotype. All isolates that showed a specific morphotype at this incubation temperature also formed the corresponding type of pellicle at the air-liquid interface. Additionally, comparing OD (optical density) values obtained by crystal violet test between groups of isolates that represent one of the three detected morphotypes (rdar, bdar and saw), statistically significant differences were detected. Based on OD values obtained by crystal violet test at both applied incubation temperatures, isolates were classified into three categories, regarding their ability to form biofilms: strong, moderate and weak biofilm producers. By comparing the amounts of the biofilms formed after 48h at 25°C and 37°C, statistically significant differences were noted (P<0.05). In this research we presented micrographs and a reconstruction of three-dimensional projections of biofilm developing phases of rdar morphotype isolates, which were obtained using confocal laser scanning microscopy.

Published: October 2015

The aim of this study was to evaluate the effects of 60 days of rose-hip and grapeseed dietary supplementation of a balanced home-cooked diet on serum oxidative stress parameters: ROMs, MDA and FRAP in army service dogs before and after regular physical exercise. The dogs were fed a balanced cooked diet as instructed by army standards until the initial blood sampling in June. Thereon the dogs were randomly allotted to 4 groups according to the dietary regime: dogs maintained on a balanced cooked diet according to army standards, branded dry dog food, cooked diet with added 500 mg rose-hip extract, and cooked diet with added 100 mg grapeseed extract for a 60 day period from June to September after which all 4 groups were fed the standard cooked meal diet. Sampling was performed at the beginning of the experiment (June), 60 days from the start of the treatment (September) and finally 60 days after the end of supplementation (November). Statistical analysis of the results included descriptive statistical parameters: mean (M), standard deviation (SD), and variation coefficient (CV%). In order to test the statistical significance of the differences between treatments a multifactor variance test (ANOVA) was performed for ROM, MDA and FRAP and the combined effects of diet, exercise and time period were observed. The initial (in June) increase in MDA and ROMs after exercise indicates the presence of oxidative stress 30 minutes after exercise. However, the antioxidative effects of rose-hip and grapeseed extracts are not conclusive, as multifactor ANOVA testing of time, diet, and exercise factors did not reveal for MDA statistically significant differences either at 60 days of supplementation nor 60 days after withdrawal of the supplements. Only one distinct exception was recorded for the prolonged antioxidative effects reflected in significantly decreased (p<0.01) ROMs before and after exercise in dogs fed the branded dry food 60 days after the end of such dietary regime (November). FRAP values tend to be higher (p>0.05) after exercise compared to before exercise in all experimental groups in November, indicating on a possible redistribution and upregulation of endogenous antioxidants during the experiment.

Published: October 2015

The objective of this study was to assess cell-free fermented culture broth of 9 Lactobacillus plantarum strains as antibiotic alternatives for the inhibition of in vitro growth of enterotoxigenic Escherichia coli (ETEC) and Shiga toxin-producing E. coli (STEC) isolated from postweaning pigs with colibacillosis and edema disease in 2014. A total of 10 ETEC and 5 STEC strains isolated from postweaning pigs were tested in antimicrobial susceptibility tests. ETEC and STEC strains used in this study possessed at least one of fimbrial, enterotoxin, and Shiga-toxin genes when tested by polymerase chain reaction. Among 9 L. plantarum strains tested, 3 strains (Lp 2-05, 2-06, and 1-03) showed inhibitory activity of in vitro growth against 10 ETEC strains (100%) and 7 strains (Lp 6-13, 3-06, 3-05, 7-01, 2-06, 1-03, and 6-05) showed inhibitory activity of in vitro growth against 5 STEC strains (100%). Three strains (Lp 3-05, 2-06, and 1-03) showed inhibitory activity of in vitro growth against 10 ETEC (100%) and 5 STEC (100%) strains. The results of this study show the inhibitory activity of cell-free fermented culture broth of L. plantarum against ETEC and STEC isolated from postweaning pigs with colibacillosis and edema disease.

Published: October 2015

Rhabdomyosarcoma is a malignant tumor of the skeletal muscles that is occasionally observed in free-living and pet birds. A case of malignant rhabdomyosarcoma in the musculature of the right wing of a captive female cockatiel (Nymphicus hollandicus) was investigated. The clinical aspect and radiographic images suggested an invasive neoplasm. Histologically, the tumor was composed of a patternless array of large primitive polygonal cells or sheets of bizarre cells with giant nuclei and atypical mitoses set in a collagenous stroma. Anaplastic cells were poorly differentiated and exhibited notable cellular and nuclear pleomorphism. Nuclei showed extreme variability in number, size, shape, chromatin distribution and nucleolar size and number. The cross striations were encountered in elongated multinucleated cells known as “strap cells” and in ovoid cells known as “racquet cells” and numerous mitotic figures were also observed. Neoplastic cells were positive for muscle actin and negative for desmin, suggesting the diagnosis of anaplastic rhabdomyosarcoma. It is the first reliable record of a rhabdomyosarcoma in a cockatiel (Nymphicus hollandicus) in Romania.

Prostate cancer is the second most common cancer worldwide for males, and the fifth most common cancer overall. Using of autogenic training could reduce the influence of ADT and raise quality of prostate cancer patients. The aim of this study was to determine the effects of autogenic training in patients with prostate cancer. Patients were divided to experimental and control group. Experimental group participated in fourteen weeks long autogenic training program. Control group performed usual daily activities. Every subject of research performed input and output diagnostics which monitored psychical states of patients by psychological standardized tests - Differential questionnaire of depression (DDF) and Questionnaire of anxiety (STAI X1). Our data showed autogenic training program significant improved depressions symptoms and anxiety in experimental research group (p ≤ 0.05), however there was no main change of depression symptoms and anxiety values for control group (p = n.s.).
Changes In Functional Movement Screen Scores Of Slovak Women’s National Football Teams

Published: October 2015

The aim of this study was to assess movement patterns by using Functional Movement Screen in three categories of Slovak women’s national football teams during two occasions interpressed with one year. The reason for this was to answer the questions: 1. if there is a tendency to perform better in the screen with respect to age category, and 2. if the players who did the screen more times and recieve recommendations, perform better after a year, irrespective to age category. Our results showed that every category achieved significant improvements (p<0.10) in total test score when compared the two occasions (2013 vs. 2014), except WU17, where significant decrement was found (p<0.01). These results probably represent the fact, that the WU17 is the less experienced category regarding FMS™, and the group where the most turbulence occurs in the nomination list. However, when we assessed the group of players who were present at both occasions of screening, irrespectively to age group they belong, results revealed significant overall improvements (p<0.05). In conclusion, we would suggest FMS™ as a useful tool to reveal potentially weak links in player's movement and therefore determine injury risk. Our results suggest that professional recommendations to remove these are effective and at least as much important as the screening scores alone.
Efficiency Of Different Teaching Models In Teaching Of Frisbee Ultimate
Authors: Žuffová Zuzana , Zapletalová Ludmila
Published: October 2015

The aim of the study was to verify the efficiency of two frisbee ultimate teaching models at 8-year grammar schools relative to age. In the experimental group was used a game based model (Teaching Games for Understanding) and in the control group the traditional model based on teaching techniques. 6 groups of female students took part in experiment: experimental group 1 (n=10, age=11.6), experimental group 2 (n=12, age=13.8), experimental group 3 (n=14, age =15.8), control group 1 (n=11, age =11.7), control group 2 (n=10, age =13.8) and control group 3 (n=9, age =15.8). Efficiency of the teaching models was evaluated based of game performance and special knowledge results. Game performance was evaluated by the method of game performance assessment based on GPAI (Game Performance Assessment Instrument) through video record. To verify level of knowledge, we used a knowledge test, which consisted of questions related to the rules and tactics knowledge of frisbee ultimate. To perform statistical evaluation Mann-Whitney U-test was used. Game performance assessment and knowledge level indicated higher efficiency of TGfU in general, but mostly statistically insignificant. Experimental groups 1 and 2 were significantly better in the indicator that evaluates tactical aspect of game performance - decision making (p<0.05). Experimental group 3 was better in the indicator that evaluates skill execution - disc catching. The results showed that the students of the classes taught by game based model reached partially better game performance in general. Experimental groups achieved from 79.17 % to 80 % of correct answers relating to the rules and from 75 % to 87.5 % of correct answers relating to the tactical knowledge in the knowledge test. Control groups achieved from 57.69 % to 72.22 % of correct answers relating to the rules and from 51.92 % to 72.22 % of correct answers relating to the tactical knowledge in the knowledge test.
On Computer-Assisted Proving The Existence Of Periodic And Bounded Orbits

Published: October 2015

We announce a new result on determining the Conley index of the Poincaré map for a time-periodic non-autonomous ordinary differential equation. The index is computed using some singular cycles related to an index pair of a small-step discretization of the equation. We indicate how the result can be applied to computer-assisted proofs of the existence of bounded and periodic solutions. We provide also some comments on computer-assisted proving in dynamics.

Influence of nuclear power unit on decreasing emissions of greenhouse gases
Authors: Stanek Wojciech , Szargut Jan , Kolenda Zygmunt , Czarnowska Lucyna
Published: October 2015

The paper presents a comparison of selected power technologies from the point of view of emissions of greenhouse gases. Such evaluation is most often based only on analysis of direct emissions from combustion. However, the direct analysis does not show full picture of the problem as significant emissions of GHG appear also in the process of mining and transportation of fuel. It is demonstrated in the paper that comparison of power technologies from the GHG point of view has to be done using the cumulative calculus covering the whole cycle of fuel mining, processing, transportation and end-use. From this point of view coal technologies are in comparable level as gas technologies while nuclear power units are characterised with lowest GHG emissions. Mentioned technologies are compared from the point of view of GHG emissions in full cycle. Specific GHG cumulative emission factors per unit of generated electricity are determined. These factors have been applied to simulation of the influence of introduction of nuclear power units on decrease of GHG emissions in domestic scale. Within the presented simulations the prognosis of domestic power sector development according to the Polish energy policy till 2030 has been taken into account. The profitability of introduction of nuclear power units from the point of view of decreasing GHG emissions has been proved.
Influence of the type of working fluid in the lower cycle and superheated steam parameters in the upper cycle on effectiveness of operation of binary power plant
Authors: Stachel Aleksander A. , Wiśniewski Sławomir
Published: October 2015

In the paper presented have been the results of the analysis of effectiveness of operation of binary power plant consisting of combined two Clausius-Rankine cycles, namely the binary cycle with water as a working fluid in the upper cycle and organic substance as a working fluid in the lower cycle, as well as a single fluid component power plant operating also in line with the C-R cycle for superheated steam, with water as a working fluid. The influence of the parameters of superheated steam in the upper cycle has been assessed as well as the type of working fluid in the lower cycle. The results of calculations have been referred to the single-cycle classical steam power plant operating at the same parameters of superheated steam and the same mass flow rate of water circulating in both cycles. On the basis of accomplished analysis it has been shown that the binary power plant shows a greater power with respect to the reference power plant.
Technical and economic aspects of oxygen separation for oxy-fuel purposes
Authors: Chorowski Maciej , Gizicki Wojciech
Published: October 2015

Oxy combustion is the most promising technology for carbon dioxide, originated from thermal power plants, capture and storage. The oxygen in sufficient quantities can be separated from air in cryogenic installations. Even the state-of-art air separation units are characterized by high energy demands decreasing net efficiency of thermal power plant by at least 7%. This efficiency decrease can be mitigated by the use of waste nitrogen, e.g., as the medium for lignite drying. It is also possible to store energy in liquefied gases and recover it by liquid pressurization, warm-up to ambient temperature and expansion. Exergetic efficiency of the proposed energy accumulator may reach 85%.

Published: October 2015

The aim of the study was to analyse the effect of the feed additive alfalfa protein concentrate (APC), on pig health. The trial involved 40 crossbred gilts and 40 crossbred castrates (Polish Landrace × Polish Large White) × Duroc of 29.0 ± 0.5 kg initial body weight. Allocation of experimental animals was into four treatment groups: the control group (C) was fed standard mixtures, without APC addition; group E-15 was fed a basal diet supplemented with 1.5% APC; and groups E-30 and E-30P were fed diets with 3.0% APC inclusion. There were two feeding systems. In the first system, animals of groups C, E-15, and E-30 were fed continuously with suitable mixtures. The second feeding system was used in group E-30P where animals received the experimental or control mixture alternating at two-week intervals. The addition of APC supplement to diets significantly increased (P ≤ 0.05) red blood cell indices, i.e. haematocrit (Ht), red blood cell count (RBC), and haemoglobin concentration (Hb) in growing and finishing periods. The analysis of enzyme activity demonstrated a markedly higher activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and especially alkaline phosphatase (ALP) in the blood plasma of pigs fed APC supplement. This increase may indicate a negative impact of APC on the animal’s liver. A positive effect of dietary APC on blood lipid parameters was associated with a decreased level of total cholesterol and reduced low-density lipoprotein fraction. Analysis of the haematological and biochemical blood indices demonstrated that APC additive may affect animal health.
“Improvisation is not allowed in a second language”: A survey of Italian lecturers’ concerns about teaching their subjects through English
Authors: Helm Francesca , Guarda Marta
Published: October 2015

English-medium instruction (EMI) is increasingly being introduced not only in universities in northern Europe but also in central and southern countries, such as Italy. However, the competences and concerns of the lecturers involved are not always considered when such developments are introduced, and support or training may not be offered. This paper reports on a survey on EMI to which 115 lecturers in a public university in northern Italy responded. The survey was carried out by the university’s Language Centre as part of the LEAP (Learning English for Academic Purposes) Project, which was developed to support lecturers in EMI. The survey sought to identify what the lecturers perceived as their strengths and weakness in English, their concerns, and also their evaluations of the experience of teaching through English if they had any. The findings discussed in this paper shed light on the needs of lecturers who are involved in EMI, which relate to methodology as well as language issues. The implications of this for European university language centres intending to support EMI at their universities are discussed in the conclusion.
Language centre teachers as researchers: The case of Finland
Authors: Rontu Heidi , Tuomi Ulla-Kristiina
Published: October 2015

Language centres in higher education are facing new challenges as they plan curricula for an increasingly diverse student body and undertake new tasks in support of the multiform internationalisation of universities. Continuing professional development clearly needs to be taken to a new level, and one way of doing this is to include research in a more systematic way. In this article, we focus on the role of research as an aspect of the development of a language centre and on human resources development in particular. Based on recent data from university language centres in Finland, we report language centre personnel’s views on research in relation to their work. The results show that they are strongly in favour of developing their professional practice by engaging in research and that they feel that research conducted in language centres should be practical and have a direct relation to the other work of language centres. We also discuss different ways of supporting a research orientation and present practical models for implementing this in the development of work.
The Applicability Of SWE In Polish Spatial Data Infrastructures - The Example Of The SensorML Language
Authors: Rossa Maciej , Rogulski Mariusz
Published: October 2015

Mobile and stationary sensors currently used to measure various environmental parameters, functioning independently or as part of monitoring networks and measurement stations, provide vast amounts of data on the state and quality of the environment on the Earth. If the data is to be used effectively, they must be exchanged and shared among IT systems. Systems which offer services of searching, exchange, sharing, visualisation and analysis of dispersed and varied data resources on the widely understood environment are, for example, spatial data infrastructures.

The article presents an overview of IT technologies and standards which offer interoperability in spatial data infrastructures. It first defines interoperability and then describes the most important issues connected with spatial data infrastructures on the example of INSPIRE. An example standard which facilitates interoperability in INSPIRE is the SensorML language, a component of Sensor Web Enablement (SWE). Its practical application is proposed – for description of processes of air monitoring in a spatial data infrastructure that is an element of the Polish national environmental monitoring plan.
Energy Aware Cluster Based Routing Scheme For Wireless Sensor Network
Authors: Roy Sohini
Published: October 2015

Wireless Sensor Network (WSN) has emerged as an important supplement to the modern wireless communication systems due to its wide range of applications. The recent researches are facing the various challenges of the sensor network more gracefully. However, energy efficiency has still remained a matter of concern for the researches. Meeting the countless security needs, timely data delivery and taking a quick action, efficient route selection and multi-path routing etc. can only be achieved at the cost of energy. Hierarchical routing is more useful in this regard. The proposed algorithm Energy Aware Cluster Based Routing Scheme (EACBRS) aims at conserving energy with the help of hierarchical routing by calculating the optimum number of cluster heads for the network, selecting energy-efficient route to the sink and by offering congestion control. Simulation results prove that EACBRS performs better than existing hierarchical routing algorithms like Distributed Energy-Efficient Clustering (DEEC) algorithm for heterogeneous wireless sensor networks and Energy Efficient Heterogeneous Clustered scheme for Wireless Sensor Network (EEHC).

Published: October 2015

In this paper we present an automatic speaker recognition technique with the use of the Internet radio lossy (encoded) speech signal streams. We show an influence of the audio encoder (e.g., bitrate) on the speaker model quality. The model of each speaker was calculated with the use of the Gaussian mixture model (GMM) approach. Both the speaker recognition and the further analysis were realized with the use of short utterances to facilitate real time processing. The neighborhoods of the speaker models were analyzed with the use of the ISOMAP algorithm. The experiments were based on four 1-hour public debates with 7–8 speakers (including the moderator), acquired from the Polish radio Internet services. The presented software was developed with the MATLAB environment.

Authors: Hayrabedyan Soren B. , Zasheva Diana Y. , Todorova Krassimira O.
Published: October 2015

Aim: The present study aims to investigate the NALP3 system and its effect on claudins in Sertoli cells using a mouse adult Sertoli cell line as a model. We focus on the Sertoli cell biology looking for the possible implications for male reproductive functions.

Materials and methods: Adult Sertoli cells were transfected with NAPL3 siRNA and treated with NOD1 (ie-DAP) and NOD2 (MDP) receptor ligands. Two dimensional gel electrophoresis was performed on lysates of non-challenged and MDP-treated Sertoli cells.

Results: There were positive claudin-5 and claudin-11 expression levels on transcript (RT-qPCR) levels. Specific protein spots in 2D gels were detected after bioinformatics analysis. This study demonstrates direct induction of tight-junction proteins probably favouring junction stability.

Conclusions: The innate immunity and tight-junction pathway integration probably have a protective role for both blood-testis immune barrier and spermatogenesis compartmentalisation maintained by the very same barrier. This integration also points the way for mechanistic research of the disturbances inflicted during an inflammatory response in the testis niche.

Infantile hemangiomas are reported in 10-12% of children less than 1 year of age, with ulceration in about 5-13% of cases. Little is known about the mechanism of this disease and explanations are still being looked for.

We present a 4-month-old female infant with haemangioma on the left buttock; the hemangioma was noticed at 2 weeks of age, progressively enlarging and ulcerated.
Application of Ionic Liquids in the Utilization of the Agricultural Wastes: Towards the One-Step Pre-Treatment and Cellulose Hydrolysis
Authors: Megyeri Gábor , Nemestóthy Nándor , Polakovic Milan , Bélafi-Bakó Katalin
Published: October 2015

Cheap, renewable lignocellulosic materials are relevant to the future of biofuel production. Wood and agricultural wastes (e.g. straw, corn stover) provide a raw material source that cannot be used for human consumption, thus biofuels from such sources do not threaten the food supply. The aim of the work was to carry out the pre-treatment and hydrolysis of lignocellulosic material in the same ionic liquid solvent (1-n-butyl-3- methyl-imidazolium-chloride, [Bmim]Cl), using ground wheat straw and a mixture of corn (Zea mays) leaf and stover, as substrates. Our measurements show that it is possible to achieve an acceptable glucose content from the cellulose by applying Cellic® CTec2 and Cellic® HTec2 enzyme complexes.
Suberoylanilide hydroxamic acid (SAHA) promotes the epithelial mesenchymal transition of triple negative breast cancer cells via HDAC8/FOXA1 signals

Published: October 2015

Inhibitor of histone deacetylases (HDACIs) have great therapeutic value for triple negative breast cancer (TNBC) patients. Interestingly, our present study reveals that suberoyl anilide hydroxamic acid (SAHA), one of the most advanced pan-HDAC inhibitor, can obviously promote in vitro motility of MDA-MB-231 and BT-549 cells via induction of epithelial-mesenchymal transition (EMT). SAHA treatment significantly down-regulates the expression of epithelial markers E-cadherin (E-Cad) while up-regulates the mesenchymal markers N-cadherin (N-Cad), vimentin (Vim) and fibronectin (FN). However, SAHA has no effect on the expression and nuclear translocation of EMT related transcription factors including Snail, Slug, Twist and ZEB. While SAHA treatment down-regulates the protein and mRNA expression of FOXA1 and then decreases its nuclear translocation. Over-expression of FOXA1 markedly attenuates SAHA induced EMT of TNBC cells. Further, silence of HDAC8, while not HDAC6, alleviates the down-regulation of FOXA1 and up-regulation of N-Cad and Vim in MDA-MB-231 cells treated with SAHA. Collectively, our present study reveals that SAHA can promote EMT of TNBC cells via HDAC8/FOXA1 signals, which suggests that more attention should be paid when SAHA is used as anti-cancer agent for cancer treatment.
Demonstrative verbs: A typology of verbal manner deixis
Authors: Guérin Valérie
Published: October 2015

This article presents a typological characterization of a class of demonstratives so far neglected in the literature: demonstrative verbs expressing manner. First, the morphological characteristics and syntactic behaviors of these demonstratives are examined to illustrate their verbal properties and to justify categorizing them as verbs. Next, their exophoric and endophoric roles in narratives and interactions are described. As their discourse usages closely replicate that of nominal demonstratives, we argue that demonstrative verbs belong to the class of demonstratives and propose to integrate them in a general typology of demonstratives.

Genetic aspects of intervertebral disc degeneration
Authors: Hanaei Sara , Abdollahzade Sina , Khoshnevisan Alireza , Kepler Christopher K. , Rezaei Nima
Published: October 2015

Intervertebral disc degeneration (IVDD) is one of the common causes of low back pain. Similar to many other multifactorial diseases, it is affected by environmental and genetic factors. Although not completely understood, genetic factors include a wide spectrum of variations, such as single nucleotide polymorphisms, which could play a significant role in the etiology of this disease. Besides, the interactions with environmental factors could make the role of genetic factors more complicated. Genetic variations in disc components could participate in developing degenerative disc disease through altering the normal homeostasis of discs. Gene polymorphisms in disc proteins (collagens I, II, III, IX, and XI), proteoglycans (aggrecan), cytokines (interleukins I, VI, and X), enzymes (matrix metalloproteinases II, III, and IX), and vitamin D receptor seem to play considerable roles in the pathology of this disease. There are also many other investigated genes that could somehow take part in the process. However, it seems that more studies are needed to clarify the exact role of genetics in IVDD.
