AbstractObjective. We investigated the effects of hydroalcoholic extract of Nigella sativa (NS) on renal tissue oxidative damage associated with propylthiouracil (PTU)-induced hypothyroidism during neonatal and juvenile growth in rats.Methods. Pregnant rats were divided into five groups designated as: 1) control; 2) propylthiouracil (PTU); 3) PTU-NS100; 4) PTU-NS200, and 5) PTU-NS400. All mothers except the control group received 0.005% PTU in their drinking water during lactation. Besides PTU, mothers in groups 3-5 received 100, 200, and 400 mg/kg of NS extract. After lactation period, the off spring continued to receive the same experimental treatment for the first 8 weeks of their life. Ten male off springs of each group were randomly selected, blood samples collected, and the kidney tissues removed.Results. The serum thyroxin concentration in PTU group was lower than control group and improved by extract. PTU increased the renal malondialdehyde (MDA), while reduced the total thiols concentrations and catalase (CAT) and superoxide dismutase (SOD) activity compared to control group. Administration of 200 and 400 mg/kg of NS extract decreased MDA level, while it increased the total thiols and 400 mg/kg increased CAT and SOD activity in renal tissues compared to PTU group. Serum creatinine and blood urea nitrogen (BUN) in PTU group was higher than in comparison with the control group. 400 mg/kg decreased creatinine, but both 200 and 400 mg/kg improved BUN concentration compared to PTU group.Conclusion. The results of this study demonstrate that the hydroalcoholic extract of NS has a protective effect on the renal tissue oxidative damage associated with PTU-induced hypothyroidism during neonatal and juvenile growth in rats.
A construct of cognitive discourse functions for conceptualising content-language integration in CLIL and multilingual education
Authors: Dalton-Puffer Christiane 
Published: June 2017

AbstractSchool-level learners who study curricular content in a language that is not their first require active support in their development of academic language, ideally in conjunction with working on said content. However, content teachers naturally orient towards the learning goals formulated for their respective subjects, while language teachers do not routinely consider them. This situation could be resolved if a zone of convergence between content and language pedagogies could be established. In this paper I argue that cognitive discourse functions (CDFs) constitute such a zone of convergence as the cognitive processes involving subject-specific facts, concepts and categories are verbalized in recurring and patterned ways during the event of co-creating knowledge in the classroom. While numerous publications make reference to such discourse functions, no coherent and theoretically explicit model of CDFs exists to date. The main purpose of this paper is, therefore, to introduce such a model that is theoretically explicit and conceptually anchored in both education and linguistics. Initial evidence for the empirical grounding of the construct is presented and suggestions are made for the further elaboration, consolidation and use of the CDF Construct introduced in this article.
Multilingual discourse competence in minority children: Exploring the factors of transfer and variation

AbstractThe paper aims to explore the mutual influence of writing competences in L1 and L2 of early bilinguals growing up in migrant contexts. Referring to the framework ofZiel des Artikels ist, zu zeigen, wie sich schriftsprachliche Kompetenzen in L1 und L2 bei Schülern mit Migrationshintergrund wechselseitig beeinflussen. Unter Bezugnahme auf dieEl objetivo del presente artículo es demostrar la influencia mutua que existe entre las competencias escritas del idioma principal (L1) y el idioma secundario (L2), en alumnos bilingües de menor edad en un contexto migratorio. Las competencias escritas de cada alumno en los dos lenguajes deben ser consideradas de acuerdo a la Dynamic Systems Theory. Se presenta un estudio realizado en Alemania con alumnos de 9.º y 10.º grado, quienes provienen de familias turcas, italianas y rusas. De este estudio se desprende un modelo, a través del cual se pueden comprender las competencias escritas de los textos narrativos y argumentativos de manera global, lo que demuestra al mismo tiempo las diferencias específicas de cada género de texto (narrativo y argumentativo) entre los idiomas como entre los diferentes alumnos. Se distingue que las competencias escritas en los dos idiomas se influencian recíprocamente, cuando el alumno ya llegó a un cierto nivel en alguno de los dos idiomas. Por otra parte, la transferencia de ciertas estructuras de un lenguaje a otro depende de varios factores extralingüísticos, la actitud personal así como las condiciones cognitivas previas.

AbstractAfforestation of marginal agricultural lands is an important issue in the land use changes running in Europe at present. The aim of the presented study is the documentation of effects of site improving material Alginite three years after afforestation of agricultural land in the locality with unfavourable hydrophysical regime. The impact was evaluated on growth parameters (height increment, mortality and foliar nutrient content) of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco), Scots pine (Pinus sylvestris L.) and a mixture of English oak (Quercus robur L.), red oak (Quercus rubra L.) and Norway maple (Acer platanoides L.) seedlings on former agricultural land in central Bohemia, Czech Republic. The research plot consists of 36 square sub-plots, each sub-plot is 400 m2 in size. Each sub-plot consists of 400 individuals, except Douglas-fir with 200 individuals. The following doses of Alginite were applied: control (variant A without Alginite), 0.5 kg of Alginite (B) and 1.5 kg of Alginite (C) on both conifers and broadleaves. The results showed that Alginite application had greater positive effect on height growth of seedlings than mortality, especially variant C. In most of the cases height increments were significantly positively affected (p < 0.05) by both variants of Alginite application only in the third year after planting. Alginite applications were also connected with differences in the foliar nutrient content, especially with higher magnesium and phosphorus values. The highest differences among Alginite variants were observed for Norway maple and English oak, while the lowest for red oak and Scots pine within all monitored parameters.
Movement Remote Command and Control in the Military Technical Systems through the Inferential Method
Authors: Grigore Dumitru 
Published: June 2017

Abstract
The research described in the paper at had approaches the interaction between the bio-signal and the remote movement control, by introducing an original mathematical model, regarding the psychophysiological inference from the EDA response bio-signals. The experiments were performed using an adequate design, consisting of two different techniques regarding bio-signals, in order to obtain, in variables corresponding to each of them, the same type of electrical behaviour. In order to establish the projective functions, a direct measurement method was used on the levels of potential in the epidermis’s alternative current, of base-(SPL) and response-type (SPR), the acquisition being executed with an integrated technical system, patented by the author in year 2013.
The statistical study targets the correlation analysis of the action of multiple stimuli on the EDA functions, respectively the analysis of the multiple correlations between the EEG and EDA patterns. Necessary in sending the remote command and control of a movement, this correlation in the electrical signal can be implemented in the BCI-type systems, offering superior possibilities of using the bio-feedback systems.
Urban Networking vs. Smart City
Authors: Păuna Carmen Beatrice 
Published: June 2017

AbstractTaking into consideration that the development of strong partnerships involving local citizens, civil society, the local economy and the various levels of government is an indispensable element for an Integrated Sustainable Urban Development, our paper is focusing on the role of an appropriate urban networking in the relationship with the objectives of a smart city. In this context, the Romanian good practices - as Oradea city - are worth to mention. In compliance with Europe 2020 Strategy’s objectives there will be discussed the particularities of urban networking in order to strengthen the resilience of cities, and to ensure synergies amongst the investments supported by European Structural and Investment (ESI) funds. According to economic literature the urban network is not a funding instrument but a way for cities to share feedback on the use of these new approaches. The estimated results of our research are related to the conclusion that the urban networks act as a forum for capacity building and exchange between the cities pioneering new techniques and developing integrated investments.

Published: June 2017

Abstract
MicroRNAs (miRNAs) are small RNA molecules which are known to take part in post-transcriptional regulation of gene expression. Here, VANESA, an existing platform for reconstructing, visualizing, and analysis of large biological networks, has been further expanded to include all experimentally validated human miRNAs available within miRBase, TarBase and miRTarBase. This is done by integrating a custom hybrid miRNA database to DAWIS-M.D., VANESA’s main data source, enabling the visualization and analysis of miRNAs within large biological pathways such as those found within the Kyoto Encyclopedia of Genes and Genomes (KEGG). Interestingly, 99.15 % of human KEGG pathways either contain genes which are targeted by miRNAs or harbor them. This is mainly due to the high number of interaction partners that each miRNA could have (e.g.: hsa-miR-335-5p targets 2544 genes and 71 miRNAs target NUFIP2). We demonstrate the usability of our system by analyzing the measles virus KEGG pathway as a proof-of-principle model and further highlight the importance of integrating miRNAs (both experimentally validated and predicted) into biological networks for the elucidation of novel miRNA-mRNA interactions of biological importance.
Effect of Missing Data on Classification Error in Panel Surveys
Authors: Edwards Susan L. , Berzofsky Marcus E. , Biemer Paul P. 
Published: June 2017

Abstract
Sensitive outcomes of surveys are plagued by wave nonresponse and measurement error (classification error for categorical outcomes). These types of error can lead to biased estimates and erroneous conclusions if they are not understood and addressed. The National Crime Victimization Survey (NCVS) is a nationally representative rotating panel survey with seven waves measuring property and violent crime victimization. Because not all crime is reported to the police, there is no gold standard measure of whether a respondent was victimized. For panel data, Markov Latent Class Analysis (MLCA) is a model-based approach that uses response patterns across interview waves to estimate false positive and false negative classification probabilities typically applied to complete data.
This article uses Full Information Maximum Likelihood (FIML) to include respondents with partial information in MLCA. The impact of including partial respondents in the MLCA is assessed for reduction of bias in the estimates, model specification differences, and variability in classification error estimates by comparing results from complete case and FIML MLCA models. The goal is to determine the potential of FIML to improve MLCA estimates of classification error. While we apply this process to the NCVS, the approach developed is general and can be applied to any panel survey.

AbstractThe main aims of this study were to determine the overwintering form and the primary inoculum ofErysiphe necator,the causal agent of grapevine powdery mildew in southern Syria. Eleven vineyards located at five different geographical sites were visited every week from March to November in 2014 and 2015. The results of field and histopathological studies showed thatE. necatorsurvived as mycelium in dormant grapevine buds during the winter season. The first flag shoots were observed shortly after bud break in spring. The number of flag shoots varied greatly according to vineyards, cultivars and years, being present on 27.4 to 61.9% of the grapevines in 2014, and on 5.2 to 40% of the grapevines in 2015. The percentage of flag shoots on the same grapevine also varied according to the year, cultivar and location. It was between 4.3 to 9.4% in 2014, and 2.1 to 3.6% in 2015. The disease was observed only on Balady and Black cultivars. Conidia were released from the second week of May to early September. The first conidia were trapped around mid-May, and the first secondary symptoms were observed on leaves from mid-May to early June according to the site. Chasmothecia were observed on leaves in 45.5% of the studied vineyards. The first observation of chasmothecia on leaves was in July, and their numbers varied greatly between vineyards and years. Chasmothecia were not detected on bark, nor were ascospores trapped at the beginning of the season. These results confirmed that the ascospores did not have any role in the initiation of spring infection. To the best of our knowledge, this is the first report of the overwintering form ofE. necatorin Syria.

Published: June 2017

AbstractIntroduction:Reindeer are adapted to long distance migration. This species can cope with variations in substrate, especially in ice and snow environment. However, few detailed studies about reindeer hoof are available. Thus this article describes the results of studies on macro- and micro-structures of reindeer hoof.Material and Methods:The gross anatomy of the reindeer hooves was examined. Stereo microscope (SM) and a scanning electron microscope (SEM) were used to observe four key selected positions of reindeer hooves. Moreover, element contents of the three selected positions of reindeer hooves were analysed using the SEM equipped with energy dispersive spectroscope.Results:Hoof bone structures were similar to other artiodactyl animals. In the microscopic analysis, the surfaces of the ungula sphere and ungula sole presented irregular laminated structure. Ungula edge surfaces were smooth and ungula cusp surfaces had unique features. Aside from C, O, and N, reindeer hooves contained such elements as S, Si, Fe, Al, and Ca. The content of the elements in different parts varied. Ti was the particular element in the ungula sole, and ungula edge lacked Mg and S which other parts contained.Conclusion:The macro- and micro-structures of the reindeer hooves showed high performance of skid and abrasion resistance. It is most probably essential to the long distance migration for the animals.

AbstractMountains provide important habitats for many species and often have high levels of biodiversity and endemism. Habitat associations of terrestrial small mammals were investigated at Wakefield Farm at the foothills of the Drakensberg Mountains, South Africa from July 2015 to January 2016. Sherman live traps were used to capture small mammals on 35 grids in six different habitats. A total of 472 individuals, from 14 species, were recorded, comprising: 10 rodents, three shrews and one golden mole. Species diversity differed across habitats and seasons. The riparian habitat had the highest species richness, diversity and abundance of small mammals. Species composition also differed across habitats with the indigenous forest and rocky outcrops supporting the most distinct assemblages.
Phylogenetic position of the Ancash leaf-eared mouse Phyllotis definitus Osgood 1915 (Rodentia: Cricetidae)
Authors: Rengifo Edgardo M. , Pacheco Victor 
Published: June 2017

Abstract
The phylogenetic position of the Ancash leaf-eared mouse Phyllotis definitus remains unresolved, as this species has been considered to be related to Phyllotis magister, Phyllotis xanthopygus or Phyllotis andium by several authors. The objective of this study was to clarify the phylogenetic position of P. definitus using 801 base pairs of cytochrome b sequences. A matrix constituted by 43 specimens was subjected to maximum likelihood, maximum parsimony and Bayesian inference analyses. Our results indicate that P. definitus is a member of the “andium/amicus” group and is closely related to Phyllotis pearsoni, supporting a set of chromosomal and morphological characters previously identified for this group.

A critical review of the proposed definitions of fundamental chemical quantities and their impact on chemical communities (IUPAC Technical Report)
Authors: Marquardt Roberto , Meija Juris , Mester Zoltan , Towns Marcy , Weir Ron , Davis Richard , Stohner Jürgen 
Published: June 2017

Abstract
In the proposed new SI, the kilogram will be redefined in terms of the Planck constant and the mole will be redefined in terms of the Avogadro constant. These redefinitions will have some consequences for measurements in chemistry. The goal of the Mole Project (IUPAC Project Number 2013-048-1-100) was to compile published work related to the definition of the quantity ‘amount of substance’, its unit the ‘mole’, and the consequence of these definitions on the unit of the quantity mass, the kilogram. The published work has been reviewed critically with the aim of assembling all possible aspects in order to enable IUPAC to judge the adequateness of the existing definitions or new proposals. Compilation and critical review relies on the broadest spectrum of interested IUPAC members.

Published: June 2017

Abstract
This work studied the growth of calcium carbonate single crystals on top of the monolayer of Fe3O4@SiO2 nanoparticles (NPs) with added external magnetic field. It showed that the occlusion process of the NPs into calcium carbonate single crystals varies as the force balance on the NPs shifts. Under no or weak magnetic field, the NPs are relatively mobile, the separation force from the substrate on NPs due to the growing calcium carbonate crystals is larger than the attraction force to the substrate by the magnetic field. The complete occlusion of the NPs into the single crystals is therefore observed. As the magnetic field strength increases, the balance shifts toward the attraction force. The mobility of NPs decreases and partial occlusion of the NPs into the single crystals is gradually observed. The findings in this study offer further insight into the occlusion process experienced by the NPs and also potential approach in engineering the force balance for the design and generation of composite materials that occlude foreign materials into their matrix.
