Escrita na Educação Infantil e Teoria Histórico-Cultural: desafios e especificidades
Authors: Lima Elieuza Aparecida de , Ribeiro Aline Escobar Magalhães , Prieto Mariana Natal 
Published: February 2018

Este artigo tem como objetivo discutir questões referentes Ã Educação Infantil, especialmente a criação da necessidade de expressão da criança por meio da escrita e as especificidades desse processo. Nosso diálogo com leitor(a) ampara-se em pesquisa bibliográfica, motivada a partir das seguintes questões: a aprendizagem da escrita restringe-se a aspectos técnicos? A aprendizagem desses aspectos efetiva a constituição de leitores e produtores de textos? Alicerçadas em pressupostos da Teoria Histórico-Cultural, compreendemos a escrita como instrumento cultural complexo (VYGOTSKI, 1995; LURIA, 1989), usado pela humanidade para comunicar e expressar pensamentos, aprendizagens e ideias. Nessa perspectiva, o ensino da escrita, nas Escolas de Educação Infantil (EEI), supera práticas alicerçadas em aspectos técnicos, expressadas na apresentação e reprodução de letras e da formação de palavras, que, por não contemplarem a essência do processo, podem limitar e comprometer o desenvolvimento pleno da criança. A fim de que a escola possa contribuir para as aprendizagens e o desenvolvimento infantil em relação à linguagem escrita, é fundamental considerar que toda aprendizagem da criança na escola tem uma pré-história. No que concerne à linguagem escrita, o desenho pictográfico e o jogo de papéis sociais são atividades que antecedem a aquisição da escrita, por impulsionarem o surgimento da representação simbólica na criança. Os estudos de Vygotski (1995) e Luria (1989) revelam o valor de a escola conhecer a pré-história da linguagem escrita como fundamento para contemplar, em suas propostas pedagógicas, as especificidades desse processo e, a partir disso, possibilitar às crianças a vivência de situações nas quais utilize a escrita como instrumento cultural, em sua função social.

Published: February 2018

The South African Bioinformatics Student Council (SASBiSC) in bioinformatics has been set up to increase the visibility of bioinformatics as well as to filter information to students within the field regarding job, funding and workshop opportunities as they arise. This is a short description of the process of setting up a national Student Council for Bioinformatics in South Africa, affiliating to the International Society for Computational Biology (ISCB). We also report two examples of activities that were carried out over the last two years that are: 1) participation in the SciFest Africa; and 2) the organisation of the first Bioinformatics Student Symposium. We hope that our experience and methods for the creation of SASBiSC and of collaborative communities can be useful to others who might want to do the same.

Abstract
The aim of the experiment with 240 ISA Brown hens fed the diets with standard or decreased Ca level was to evaluate the effect of selected feed additives on laying performance and eggshell quality. The hens were allocated to 10 treatments, each containing 12 cages (replicates) of 2 birds. A 2 × 5 experimental arrangement was used. From 26 to 70 wks of age, experimental diets containing 3.20 or 3.70% Ca were used. The diets were either not supplemented, or supplemented with sodium butyrate, probiotic bacteria, herb extracts blend or chitosan. The decreased dietary Ca reduced eggshell quality indices in older hens (43-69 wks) (P<0.05) without effect on performance indices. The addition of the probiotic, herb extracts, or chitosan increased the laying rate (P<0.05). In older hens, i.e. at 69 wk, chitosan increased eggshell thickness and breaking strength, while herb extracts increased eggshell thickness (P<0.05). There was no interaction between the experimental factors in performance and eggshell quality. The used feed additives had no influence on fatty acid profile of egg lipids, however diet supplementation with chitosan decreased cholesterol concentration in egg yolk lipids (P<0.05). It can be concluded that such feed additives as probiotic, herb extracts, or chitosan may positively affect performance and eggshell quality, irrespective of Ca dietary level.
Limited Liability and High Bids in English Auctions
Authors: Wang Tao , Wang Ruqu 
Published: February 2018

Abstract
In this paper, we investigate how limited liability affects firms’ bidding behavior in license auctions. We focus on a model where firms first seek financing from banks, then bid for the licenses, and the winning firms set prices in a product market with uncertain demand. In a model of one license, the winning firm becomes a monopoly. A higher bid induces a higher product price. In a model of two licenses, a higher bid provides a positive externality to all other firms. In both models, bids are extremely high in the English auction, and the English auction always generates more revenue than the first-price/discriminatory auction.

Authors: Rutkowska Katarzyna , Bergier Józef , Kasprowicz Marcin 
Published: February 2018

AbstractPurpose. One of the keys to identifying health problems from the holistic perspective is the knowledge of Type D personality (distressed personality). Diagnosing this personality disorder among female football players may help sports psychologists, coaches, parents/caregivers, and all those engaged in training new sports entrants develop guidelines on how to resolve the problem. Methods. The study involved female footballers representing a Polish Ekstraliga football club, AZS-PSW Biała Podlaska, and was conducted with the use of the Polish adaptation of the DS14 scale. Results. In a group of 21 footballers, 7 (33.3%) were diagnosed with Type D personality. Besides, a negative correlation was noted between the level of satisfaction with playing football and one of the dimensions of Type D personality - negative emotionality. Conclusions. The results of the study may be applicable in formulating practical recommendations while preparing mental training programmes.
Warum Germanien? Überlegungen zu den Motiven der augusteischen Expansionspolitik
Authors: Eich Armin 
Published: February 2018

Zusammenfassung
Während der Regierungszeit des Augustus versuchte das Imperium Romanum in einer großen militärischen Anstrengung, die Stammesterritorien östlich des Rheins zu unterwerfen und zu annektieren, ein Plan, der schließlich scheiterte. Nach einer bereits früher durch den Autor vertretenen Auffassung waren bei dem Eroberungsplänen (in Germanien wie generell bei den augusteischen Kriegen) vor allem fiskalische Gesichtspunkte leitend, da sich die Reichsregierung gezwungen sah, für das neue stehende Heer eine stabile Finanzierungsgrundlage zu schaffen. Diese These wird vertieft und gegen Kritik verteidigt. Gegen das Argument, dass die rückständigen und unterentwickelten germanischen Gebiete keinen Anreiz für einen vor allem fiskalisch denkenden Eroberer boten, wird die Auffassung entwickelt und begründet, dass es dem kaiserzeitlichen Imperium nicht um kurzfristige Beuteabschöpfung ging, sondern eine langfristige In-Wert-Setzung der annektierten Territorien das Ziel war. Insofern kann durchaus von einem römischen „Entwicklungsimperialismus“ gesprochen werden.
Peter der Große und Russlands Fenster nach Asien
Authors: Renner Andreas 
Published: February 2018

Zusammenfassung
Peter der Große ist als der Zar in die Geschichte eingegangen, der Russland für Europa öffnete und zu einer Großmacht in Europa verwandelte. In diesem Narrativ kommt Asien nicht vor. Doch so sehr die Transformation und der Aufstieg des Petrinischen Russland seine westliche Nachbarn beeindruckte – beide Prozesse waren auch deswegen möglich, weil das Zarenreich seit Jahrhunderten ein Imperium in Asien gewesen war und bis zu seinem Untergang blieb. Dieser Aufsatz untersucht, was die Westorientierung Peters für die asiatischen Reichsteile und Nachbarn Russlands bedeutete. Zar Peter knüpfte einerseits die diplomatischen und Handelskontakte seiner Vorgänger weiter, scheiterte aber andererseits daran, die Mächtekonstellation in Asien militärisch so nachhaltig zu verändern wie die im Nordosten Europas. Trotz der starken Faszination Peters für den „Westen“ bildete der Respekt gegenüber bzw. das Interesse an China, Japan oder Indien eine Grundlage seiner Politik. Der Traum, Russland zu einer kulturellen und ökonomischen Brücke zwischen Europa und Asien zu verwandeln, entstand in der Petrinischen Zeit und wirkt bis in die Gegenwart. Dass die Forschung lange Zeit mehr an Russland in Europa als an Russland in Asien interessiert war, folgte sowohl aus der Selbststilisierung Peters und seiner Nachfolger zu europäischen Herrschern als auch aus den historiographischen Traditionen des 19. Jahrhunderts.

Published: February 2018

AbstractThe monitoring of power quality is a central topic for both household electrical and industrial equipment. Typically, the lacks of quality in a power system (both a public mains and an industrial power supply network) involve interruptions and deviations of the actual supply signals from the nominal characteristics, with potential annoying effects in electrical power systems and problems in industrial and communication apparatus. In this paper, the design and implementation of a measuring system based on a high-performance microcontroller that carries out the power quality analysis of the mains is presented. The system measures the fundamental parameters related to the system under monitoring, that can be a single or a three phase network. The proposed measurement instrument is mainly based on the Microchip PIC32MZ2048ECH100 Digital Signal Controller (DSC) and the Texas Instruments ADS8558 A/D converters (ADCs). Starting from voltage and current sampled values, simultaneously acquired by the converters, the DSC calculates the following parameters: frequency; RMS voltage; RMS current; phase shift; active power; reactive power; apparent power; THD. The measured parameters are also externally transmitted via a serial link. In the paper a prototype of the proposed instrument is described. It is linked to a PC and results shown on a LabVIEW based user interface, reporting also results from lab tests during the metrological characterization phase. Its main features (cost effectiveness, reduced dimensions and low power consumption) make it suitable for installation into existing electric cabinet of civil and commercial users. The continuous and real-time monitoring capability, managed both locally or remotely, is one of the most interesting features.

Using an extension of Lyapunov method sufficient conditions for the stability of positive nonlinear systems are given. The considerations are extended to fractional nonlinear systems.
Geodetic analysis of disputed accurate qibla direction
Authors: Saksono Tono , Fulazzaky Mohamad Ali , Sari Zamah 
Published: February 2018

AbstractMuslims perform the prayers facing towards the correct qibla direction would be the only one of the practical issues in linking theoretical studies with practice. The concept of facing towards the Kaaba in Mecca during the prayers has long been the source of controversy among the muslim communities to not only in poor and developing countries but also in developed countries. The aims of this study were to analyse the geodetic azimuths of qibla calculated using three different models of the Earth. The use of ellipsoidal model of the Earth could be the best method for determining the accurate direction of Kaaba from anywhere on the Earth’s surface. A muslim cannot direct himself towards the qibla correctly if he cannot see the Kaaba due to setting out process and certain motions during the prayer this can significantly shift the qibla direction from the actual position of the Kaaba. The requirement of muslim prayed facing towards the Kaaba is more as spiritual prerequisite rather than physical evidence.
Linguistic landscape in the city of Isfahan in Iran: The representation of languages and identities in Julfa
Authors: Rezaei Saeed , Tadayyon Maedeh 
Published: February 2018

AbstractThis paper reports on the diversity of languages displayed in the linguistic landscape of Julfa district, a largely Armenian dominated area, in the city of Isfahan in Iran. The data included a corpus of 323 photographs taken from the top-down and bottom-up signage in this quarter of the city. Ethnographic fieldwork was also conducted to reach a deeper understanding of the linguistic landscape in Julfa. The results of the analyses indicated that Julfa, as home to Armenians in diaspora and also a luxurious neighborhood frequented by more modern strata of the Isfahani society, is occupied more noticeably with Persian and English language and to a lesser extent with Armenian language. The findings further revealed that this neighborhood represents not only Iranian but also Armenian and Christian identities. The results are analyzed based on Bourdieu’s theory of language as a symbolic power. Furthermore, the collective identity and language ecology of Julfa in Isfahan are discussed. At the end, some lines of research for further studies in the LL of Iran are provided.

Authors: Godek Piotr , Ruciński Wojciech , Brzuszkiewicz-Kuźmicka Grażyna 
Published: February 2018

Abstract
Thoracic Outlet Syndrome (TOS) is one of the most controversial compression (vascular and neurogenic) syndromes both due to the fact it is difficult to diagnose and because of the lack of generally accepted standard procedures. It is estimated that this condition occurs in 10 out of 100 000 people, while clinical examinations reveal that arterial symptoms are more common than neurogenic ones. This work presents a pathogenesis of the functional type of the syndrome with regard to contemporary studies analysing the effects of currently applied forms of conservative treatment. The study presents arguments concerning the significance of proper diagnosis which makes it possible to individualise the therapy according to current trends in rehabilitation mentioned in the available literature and resulting from the authors’ own experience.
Advances in fixed-bed reactor modeling using particle-resolved computational fluid dynamics (CFD)
Authors: Jurtz Nico , Kraume Matthias , Wehinger Gregor D. 
Published: February 2018

AbstractIn 2006, Dixon et al. published the comprehensive review article entitled “Packed tubular reactor modeling and catalyst design using computational fluid dynamics.” More than one decade later, many researchers have contributed to novel insights, as well as a deeper understanding of the topic. Likewise, complexity has grown and new issues have arisen, for example, by coupling microkinetics with computational fluid dynamics (CFD). In this review article, the latest advances are summarized in the field of modeling fixed-bed reactors with particle-resolved CFD, i.e. a geometric resolution of every pellet in the bed. The current challenges of the detailed modeling are described, i.e. packing generation, meshing, and solving with an emphasis on coupling microkinetics with CFD. Applications of this detailed approach are discussed, i.e. fluid dynamics and pressure drop, dispersion, heat and mass transfer, as well as heterogeneous catalytic systems. Finally, conclusions and future prospects are presented.
Administration of valine, leucine, and isoleucine improved plasma cholesterol and mitigated the preatherosclerotic lesions in rats fed with hypercholesterolemic diet

Published: February 2018

Abstract
Hypercholesterolemia has a major contribution to the occurrence and progression of atherosclerotic lesions. Recent studies report the involvement of branched-chain amino acids in cholesterol methabolism. The aim of this research was to evaluate the role of valine, leucine and isoleucine on the occurrence and progression of atherosclerosis in rats receiving hypercholesterolic diet. Material and methods: 50 male Wistar rats distributed into five groups with the following type of diets: group I (control) received standard diet; group II - cholesterol; group III - cholesterol and valine; group IV - cholesterol and leucine; group V - cholesterol and isoleucine. The experimental study was conducted over a period of 2 months. The animals were evaluated for the serum levels of total cholesterol at the beginning of the experiment, after 1 month and after 2 months. The collected tissue fragments of heart and aorta were prepared for the examination by optical microscopy in order to identify the atherosclerotic changes. Results: The most increased values of serum cholesterol were recorded in rats from group II (p=0.001), for the second and third evaluation. The histological examination showed early histopathological lesions on the vascular intima for the groups treated with cholesterol, valine, leucine, and isoleucine. These early changes (the occurrence of some superficial endothelial erosions, adhesion of erythrocytes and platelets) were correlated with the degree of the arterial wall damage, of the leukocytes adhesion to the arterial intima, and the discontinuities of the internal elastic lamina. Conclusion: The comparative study of the effects of the three essential amino acids revealed that valine induced a faster response than leucine and isoleucine on the improvement of biochemical parameters, but there were no significant differences between the three amino acids in terms of their protective ability, demonstrated by the histopathological lesion assessment.

Abstract
Introduction. The unsatisfactory results of the survival in patients with acute lymphoblastic leukemia (ALL) until 2000 in our center have led us to improve the approach of diagnosis and therapy. Since 2003 in all patients the following have been performed: flow cytometry, conventional genetic diagnosis, FISH (fluorescent in situ hybridization), and molecular biology. Objectives. Our aims were to identify solutions to increase patients’ survival. Patients and method. It is a single-center, retrospective study of 136 patients with ALL treated at 3rd Pediatric Clinic of Timisoara, over a period of 10 years (2003-2012), where survival was assessed. Results. Morphologically, 86% of the patients were L1 type, 13% L2 type and 1% L3 type. Flow citometry revealed that 68% were ALL with B precursors, and 19% with T immunophenotype. Acute leukemia with mixed phenotype (biphenotypic) was identified in 2.3% of patients and 10.7% of the forms were acute leukemia with myeloid markers. In 27.7% of patients, mutations were detected by the RT-PCR method, the most commonly identified was TEL-AML1 (ETV6- RUNX1) accounting for 12.7% of the cases. Relapse-free survival at 5 years for the entire group was 59%, and for the group treated between 2008 and 2012 it was 72%. Conclusion. Our analysis confirms the decisive value of laboratory investigations for the prognosis and improvement of supportive therapy.
