Published: December 2014

The article considers one of the ways to create open information and educational space on the basis of interaction of two social environments: school and museum.Four models are analyzed on the basis of the following criteria: frequency and duration of interaction and forms of carrying out studies in "school and museum"system. For ensuring this interaction authors offer a special museum and educational complex representing the educational form that materialize the teacher�s model of training of pupils and allow its implementation in educational process.Conceptual aspects of the offered complex are provided and interaction models are presented: incidental, periodic, systematic and system. These models place teacher, pupil and their interaction into museum space. The article presents a short characteristic of the allocated models, along with forms of estimating the results of pupil�s interaction with museum space.

Published: December 2014

Introduction

The joint British Association of Plastic, Reconstructive and Aesthetic Surgeons/British Orthopaedic Association standards define best practice management in open diaphyseal fractures of the lower limb. The aim of our study was to review the regional approach and experience in South West England and Wales. A further objective was to evaluate service provision with regard to the standards’ key recommendations.

Methods

A prospective audit was undertaken of open diaphyseal fracture patients. Compliance with published standards within all orthoplastic services in South West England and Wales was assessed, and facilities were evaluated.

Results

A total of 86 patients were managed between October 2012 and March 2013. This was a 56% increase from 2008. Over half (56%) presented directly to the orthoplastic services with all patients undergoing debridement within 24 hours. Two-thirds (66%) of procedures were in daylight hours excluding those requiring immediate surgical intervention. Adherence to correct antibiotic therapy was 88% at admission, 50% at primary surgery and 62% at definitive surgery. Almost two-thirds (60%) of primary procedures were performed with combined senior orthoplastic teams, with 81% achieving definitive soft tissue coverage and fixation within seven days. Compliance improved in units with larger patient caseloads and where there was an early combined approach during daylight hours.

Conclusions

Increased open lower limb fracture workload was demonstrated across South West England and Wales, probably owing to centralisation of trauma services. An improvement in early transfer of this patient group to orthoplastic facilities has allowed all patients to be assessed and debrided within the recommended timeframe. Standards were most likely to be met in those centres seeing higher numbers of injuries and when there was a daylight hours procedure by combined orthoplastic teams.

Published: December 2014

BACKGROUND

Spinal muscular atrophy (SMA) is a motor neuron disorder caused by the absence of a functional survival of motor neuron 1, telomeric (SMN1) gene. Type I SMA, a lethal disease of infancy, accounts for the majority of cases. Newborn blood spot screening (NBS) to detect severe combined immunodeficiency (SCID) has been implemented in public health laboratories in the last 5 years. SCID detection is based on real-time PCR assays to measure T-cell receptor excision circles (TREC), a byproduct of T-cell development. We modified a multiplexed real-time PCR TREC assay to simultaneously determine the presence or absence of the SMN1 gene from a dried blood spot (DBS) punch in a single reaction well.

METHOD

An SMN1 assay using a locked nucleic acid probe was initially developed with cell culture and umbilical cord blood (UCB) DNA extracts, and then integrated into the TREC assay. DBS punches were placed in 96-well arrays, washed, and amplified directly using reagents specific for TREC, a reference gene [ribonuclease P/MRP 30kDa subunit (RPP30)], and the SMN1 gene. The assay was tested on DBS made from UCB units and from peripheral blood samples of SMA-affected individuals and their family members.

RESULTS

DBS made from SMA-affected individuals showed no SMN1-specific amplification, whereas DBS made from all unaffected carriers and UCB showed SMN1 amplification above a well-defined threshold. TREC and RPP30 content in all DBS were within the age-adjusted expected range.

CONCLUSIONS

SMA caused by the absence of SMN1 can be detected from the same DBS punch used to screen newborns for SCID.
Zebra: A document intersecting the photographic and choreographic
Authors: Peacock Allison
Published: December 2014

This photo essay documents the research and production of the performance Zebra, while avoiding a strict replication of the performance. This photo collection is an independent artwork, reflecting on the potential for image-based work to simultaneously represent encounters in performance and artistic research. The essay operates in the choreographic style of the performance, suggesting a connection between visual patterns and the selection of a lineage of events. The repetition, replication, and representation of a sunset is key, as it uses the photographic medium to connect the fleeting aspect of the performance with the occurrence of a sunset. The Zebra’s appearance is mediated through digital technology, a metaphor for choreographic camouflage.
Extending the flipped classroom model: Developing second language writing skills through student-created digital videos
Authors: Engin Marion
Published: December 2014

Abstract: This paper describes a project which aimed to leverage the students’ interest and experience of technology and multi-modal environments in an academic English writing course. Students were expected to follow a model, research a topic, and craft a digital video tutorial on an aspect of academic writing which would form part of the established flipped classroom model. Evaluation from students suggests that student-created videos can promote deeper understanding of the topic through the activity of teaching, as well as encourage students to monitor their English and strive for accuracy. However, it was also noted that students prefer a teacher explanation than a peer explanation and there were concerns over the “trustworthiness” of a peer-produced video tutorial.
Cold calling and web postings: Do they improve students’ preparation and learning in statistics?
Authors: Levy Dan , Bookin Josh
Published: December 2014

Getting students to prepare well for class is a common challenge faced by instructors all over the world. This study investigates the effects that two frequently used techniques to increase student preparation -- web postings and cold calling -- have on student outcomes. The study is based on two experiments and a qualitative study conducted in a statistics course that Masters in Public Policy (MPP) students take in their second semester at the Harvard Kennedy School. When used together, web postings and cold calling seem to increase the amount of time that students devote to reading before class by about an hour. This effect is both statistically and practically significant. However this increase in pre-class reading did not translate into increased learning (measured by average test scores on the midterm exam). Neither of the two techniques seems to be better than the other one at increasing reading time, test scores, and other student outcomes.

Synthesis of lignin polyols via oxyalkylation with propylene carbonate
Authors: Kühnel Isabell , Podschun Jacob , Saake Bodo , Lehnen Ralph
Published: December 2014

An efficient, nontoxic, and solvent-free oxyalkylation of European beech wood organosolv lignin (OL) has been developed. Two approaches were studied: a direct reaction of lignin with propylene carbonate (PC) and a two-step reaction of lignin with maleic anhydride (MA) followed by oxyalkylation with PC. The structural analysis of lignin polyols was performed by 1H NMR, 13C NMR, 31P NMR, and FTIR spectroscopy. It was demonstrated that PC was able to almost completely oxypropylate aliphatic and phenolic OH groups. Moreover, the carboxylic acid groups of maleated OL were fully oxypropylated by PC. This modification strongly facilitates the generation of a uniform lignin polyol applicable as a biobased component in polyurethanes and polyesters based on cyclic organic carbonates.
Comparison of ZnO nanorod array coatings on wood and their UV prevention effects obtained by microwave-assisted hydrothermal and conventional hydrothermal synthesis
Authors: Fu Yanchun , Fu Wansi , Liu Yongzhuang , Zhang Guozheng , Liu Yixing , Yu Haipeng
Published: December 2014

ZnO nanorod array coatings were successfully synthesized on wood surfaces using a conventional hydrothermal (CHT) and a microwave-assisted hydrothermal (MWHT) method. The reaction time of the MWHT method at high temperature was only 1/12th that of the CHT method. The MWHT-ZnO nanorods exhibited better crystallinity than those produced by the CHT method. The ZnO nanorod had a wurtzite crystal structure oriented along the c-axis. The MWHT nanorods with their higher (002)/(101) ratio were more conducive and improved the orientation degree of the ZnO nanorods. Field emission scanning electron microscopy (FE-SEM) images showed that the MWHT-ZnO nanorods had smaller diameters and narrower size distributions than those produced by the CHT method. However, both methods formed well-aligned array coatings that covered the wood surfaces, and the two coatings had similar UV protecting effects and inhibited discoloration.

Published: December 2014

Background: Variants of fat mass and obesity associated gene (FTO) and melanocortin-4 receptor gene (MC4R) are related to obesity, overweight and type 2 diabetes.

Objectives: To examine the presence of FTO and MC4R variants in Greek newborns.

Subjects and methods: A total 1530 newborns of Greek origin were subjected to genetic testing for rs9939609 (FTO) and for rs17782313 (MC4R) variants using dried blood spot (DBS) analysis.

Results: Some 20.2% of newborns carried none of the tested variants. FTO homozygotes and FTO heterozygotes correspond to 18.0% and 45.9% of neonates, respectively. MC4R homozygotes and MC4R heterozygotes were identified in 6.7% and 36.3% of neonates, respectively. Of the infants, 2.2% carried both variants in homozygosity, whereas heterozygotes for both variants correspond to 16.7% of the tested neonates.

Conclusion: The results indicate high prevalence of homozygosity and heterozygosity for tested variants. Early screening via DBS may be beneficial in order to adopt a healthy lifestyle.
Correlation of cervical length, fetal fibronectin, phIGFBP-1, and cytokines in spontaneous preterm birth up to 14 days from sampling
Authors: Hadži-Lega Marija , Markova Ana Daneva , Stefanovic Milan , Tanturovski Mile
Published: December 2014

The aim of this study was to determine the relationship between sonographic cervical length, fetal fibronectin (fFN), phIGFBP-1 (actim partus test), cytokines (IL-6, IL-2R, and TNF-α), and spontaneous preterm birth (SPTB) up to 14 days from sampling.

Fifty-eight patients were recruited in a period of 6 months from September 2013 until March 2014 with symptoms or complaints suggestive of preterm labor. Consenting women were treated according to usual hospital protocol, with addition of vaginal swabs taken for fetal fibronectin, phIGFBP-1 (actim partus test) and cervical IL6, IL2R, and TNF-α. The outcome variable was occurrence of preterm delivery within 14 days from the day of hospital admission.

Thirty-six patients (62.07%) were delivered within 14 days from admission. Our results indicated that the cervical length significantly inversely correlates with the concentration of IL-6 in the CVF (Spearman’s coefficient R=–0.382, P<0.05). Cervical length also correlated with a positive phIGFBP-1 test, i.e., patients with a positive test had an average cervical length of 18.5±4.63 mm, which is significantly lower than patients with a negative test –23.43±7.39 mm (P=0.003).

The studied biochemical markers were only moderately successful in the prediction of preterm delivery.
New neutral and lipophilic technetium complexes based on a cytectrene moiety: synthesis, characterization and biological evaluation
Authors: El Aissi Radhia , Malek-Saied Nadia , Saidi Mouldi , Mallet-Ladeira Sonia , Coulais Yvon , Benoist Eric
Published: December 2014

The synthesis, characterization and biological evaluation of five neutral and lipophilic 99mTc-complexes, so-called
cytectrenes, obtained from N-substitutedferrocenecarboxamide derivatives are reported. N-substitutedferrocenecarboxamide starting
materials were obtained in two steps, with good yield and were fully characterized by classical spectroscopic methods including X-ray
diffraction analysis for one of them. Using a microwave strategy for the 99mTc-radiolabelling step, each cytectrene
were obtained quickly (radiolabelling time < 5 min), from modest to good yield. The 99mTc-complexes,
characterized by HPLC comparison with cold rhenium complex analogues, are stable, neutral and lipophilic (log P
o/w ranged
between 1.8 and 2.9). Unfortunately, despite such suitable features, in vivo studies of two of them gave poor results, in
terms of brain uptake. Both radiocompounds exhibited the maximum brain accumulation of 0.31% ID/g and 0.26% ID/g at
5 min post-injection, respectively, followed by a very fast washout from the brain (0.06% ID/g and 0.07%
ID/g at 30 min post-injection, respectively). Although our ligand systems exhibited high stability against exchange
reactions with blood proteins, the high radioactivity level in stomach, increasing with time, suggests in vivo decomposition
of our complex to pertechnetate.
Degradation of morphine and codeine by gamma radiation in methanol solution
Authors: Kantoğlu Ömer , Ergun Ece
Published: December 2014

The high concentrations of opiate and solvent in wastewater are toxic
to biological life and affect the aquatic environment. Therefore, it
must be treated by an advanced treatment process such as ionizing
radiation. Effect of organic media on morphine and codeine during
gamma irradiation was determined for the first time in this
paper. Samples were irradiated at ambient temperature and in air
environment at various doses (0, 10, 20, 30, 40, 50 and
60 kGy). Gamma irradiation-induced changes in the molecular
structure of morphine and codeine were monitored by direct infusion
electrospray ionization mass spectrometry in positive ion mode. The
mass of the by-products were appeared to be more than the mass of the
original alkaloids. Molecular structures of the by-products and
reaction pathways were proposed. Oxygenated morphine and oxygenated
codeine were identified in the presence of oxygen. However, solvent
radical addition reactions were observed as the main mechanism for the
by-product formation in oxygen-free irradiation. The results indicated
that 89% of morphine and 98% of codeine were
degraded at dose of 50 kGy. In addition, alkaloids and
their by-products were not detected above 50 kGy. Here, we
demonstrated that ionizing radiation process is a promising method to
remove morphine and codeine in solvent/opiate rich industrial
wastewater.
Development of a production scale purification of Ge-68 from irradiated gallium metal
Authors: Fitzsimmons Jonathan M. , Mausner Leonard
Published: December 2014

Germanium-68 (Ge-68) is produced by proton irradiation of a gallium metal target and purified by organic extraction. The Ge-68 can be
used in a medical isotope generator to produce Gallium-68 (Ga-68) which can be used to radiolabel PET imaging agents. The emerging use
of Ge-68 in the Ga-68 medical isotope generator has caused us to develop a new purification method for Ge-68 that does not use toxic
solvents. The purpose of this work was to develop a production scale separation of Ge-68 that utilizes a leaching step to remove a bulk
of the gallium metal, followed by purification with Sephadex© G25. Production scale (300 mCi) purification was
performed with the new method. The purified Ge-68 contained the highest radioactivity concentration of Ge-68 produced at BNL; the
sample meet Department of Energy specifications and the method had an excellent recovery of Ge-68.

Markovianness and conditional independence in annotated bacterial DNA
Authors: Hart Andrew , Martínez Servet
Published: December 2014

We explore the probabilistic structure of DNA in a number of bacterial genomes and conclude that a form of Markovianness is present at the boundaries between coding and non-coding regions, that is, the sequence of START and STOP codons annotated for the bacterial genome. This sequence is shown to satisfy a conditional independence property which allows its governing Markov chain to be uniquely identified from the abundances of START and STOP codons. Furthermore, we show that the annotated sequence of STARTs and STOPs complies with Chargaff’s second parity rule.
Effect of Reaction Kinetics on Graphene-Edge Morphology and Composition
Authors: Whitesides Russell , Frenklach Michael
Published: December 2014

New simulations of graphene growth in flame environments are
presented. The simulations employed a kinetic Monte Carlo (KMC)
algorithm coupled to molecular mechanics (MM) geometry optimization to
track individual graphenic species as they evolve. Focus was given to
incorporation of five-member rings and resulting curvature and edge
defects. The model code was re-written to be more computationally
efficient enabling a larger set of simulations to be run, decreasing
stochastic fluctuations in the averaged results. The model also
included updated rate coefficients for graphene edge reactions
recently published in the literature. Sensitivity analysis, enabled by
the more efficient coding, confirmed the importance of the updated
rates as well as providing further insight on key reactions
controlling layer growth and morphology. The new KMC code was applied
to simulate graphene-layer growth in the environments of laminar
premixed flames. In these flame simulations, C-H ratios
of evolving structures were computed and compared to those from
experiment and from an alternate model.
VPAC2 receptor expression in human normal and neoplastic tissues: evaluation of the novel MAB SP235
Authors: Schulz Stefan , Mann Anika , Novakhov Benjamin , Piggins Hugh D , Lupp Amelie
Published: December 2014

The vasoactive intestinal peptide receptor 2 (VPAC2) is widely distributed throughout the body and is also overexpressed in a variety of human neoplastic tissues. However, little is known about its precise tissue distribution, regulation and function, which is in part be due to the lack of specific monoclonal anti-VPAC2 antibodies. In this study, we extensively characterised the novel rabbit monoclonal anti-VPAC2 antibody (clone SP235) using transfected cells and mouse, rat and human tissues. SP235 was then subjected to a comparative immunohistochemical study on a series of 167 histological specimens from formalin-fixed, paraffin-embedded human tumours and adjacent normal tissues. SP235 detected a broad band migrating at a molecular weight of 50–70 kDa in western blotting analyses of various mouse tissues as well as VPAC2- but not VPAC1-transfected human embryonic kidney 293 cells. SP235 yielded an efficient immunostaining of distinct cell populations in human tissue samples with a predominance of plasma membrane staining, which was completely abolished by preadsorption with its immunising peptide. SP235 immunohistochemistry detected VPAC2 receptors in lymphocytes present in spleen, tonsils, lymph nodes and Peyer's patches, chief cells of gastric mucosa, exocrine and endocrine pancreas, kidney tubules and blood vessels. In addition, VPAC2 was observed in thyroid, gastric and lung carcinomas, pancreatic adenocarcinomas, sarcomas and neuroendocrine tumours. SP235 may prove of great value in the identification of VPAC2 receptors during routine histopathological examination. VPAC2 visualisation with this simple and rapid immunohistochemical method will facilitate identification of candidate tumours for vasoactive intestinal peptide (VIP)-based diagnostics or therapeutic interventions.
La monstruosidad en G. Canguilhem y M. Foucault. Una aproximación al monstruo biopolítico
Authors: Torrano Andrea
Published: December 2014

El artículo indaga la noción de monstruo a partir de los desarrollos de Georges Canguilhem y Michel Foucault. Canguilhem se centra en los estudios teratológicos, donde la monstruosidad es una anomalía compleja y observa que la anomalía es identificada con la anormalidad. Por su parte, Foucault concibe la monstruosidad como un concepto jurídico (jurídico-biológico y jurídico-moral). El monstruo es el antecesor del anormal. A pesar que Foucault señala que el marco de referencia del monstruo es la ley, mostraremos que el monstruo debe ser puesto en relación a la norma. El monstruo es un concepto biopolítico.DOI  http://dx.doi.org/10.15304/ag.34.1.1594
"Leer lo que nunca fue escrito": hacia una hermenéutica política
Authors: Kuffer Dinerstein Paula
Published: December 2014

En una nota de Sobre el concepto de historia Walter Benjamin define el principio histórico: «Leer lo que nunca fue escrito, se dice en Hofmannsthal. El lector en el que debe pensarse aquí es el historiador verdadero.» La historia se caracteriza como imagen dialéctica de la memoria: no está fragmentada en relatos sino en imágenes que sobrevienen de improviso y sólo pueden leerse como destellos que brillan en el ahora de la rememoración. Este ahora de la legibilidad es la contrapartida exacta del principio hermenéutico corriente, según el cual toda obra puede ser en cualquier instante objeto de una interpretación infinita, en el doble sentido de que no se agota jamás y de que es posible independientemente de su situación histórico temporal.

Measuring well-being for public policy: a freedom-based approach
Authors: Cenci Alessandra
Published: December 2014

Este artículo pone en cuestión la adecuación de los enfoques convencionales de la Calidadde Vida (QL) e intenta realizar una contribución al debate existente acerca de la revisión, integración o mejora de las métricas del bienestar tal como son usadas tradicionalmente en la bibliografía de indicadores estadísticos. Como una alternativa, este estudio basa sus principales supuestos en el Enfoque de la Capacidad (CA) de Amartya Sen. La principal hipótesis es que los análisis del bienestar que se basan en mediciones puramente monetarias o que olvidan la importancia del valor intrínseco de la libertad (y se fijan solo en sus efectos instrumentales) impiden adquirir imágenes adecuadas de las auténticas condiciones de vida de la gente en las complejas sociedades contemporáneas y, de ese modo, perjudican el diseño de la política pública. Esta hipótesis es verificada y comprobada tanto a través de una discusión teórica como también por medio de un análisis empírico de datos estadísticos de la OCDE. Lo que nuestras conclusiones indican es la gran importancia de incrementar la libertad para conseguir mejores resultados sociales e individuales.DOI  http://dx.doi.org/10.15304/ag.34.1.2157

Suspended sediment transport in coastal zone by tidal flow. Part I: Models of SPM vertical distribution
Authors: S. M. Anttsyferov , T . M. Akivis
Published: December 2014

The aim of the study is to develop methods for prediction of the vertical distribution of characteristics of sand and aleurite sediment suspended by tidal flow for the averaging time either divisible by tidal period (the first order model) or much less than it is (the second order one). The bottom is assumed to be erodible with possible formation of ripples. Part I: The theoretical and laboratory study of steady flow with suspension is used to develop the solution. The concentration field of heterogeneous sediment is considered as a sum of those of homogeneous groups of particles (fractions) moving under the same regulations. In the first order model, the hydrodynamical characteristics of the tidal flow are represented by their constant effective values. In the second order model the tidal flow is represented by the series of consecutive steady states (steps).

The practical exploitation of engineering structures needs very much a simple criterion for checking safety of structures instead of reliability index that is very difficult to be computed within the probabilistic theory. This paper deals with establishment of a simple criterion for checking safety of column-like structure based on deterministic analysis. The criterion consists of bound of the flexural displacement at the top of column that is conducted from the displacement analysis combined with ultimate state for the structure.

The thickness functions of the shells of revolution subjected to axisymmetrical loads
Authors: Nhu Ngo Huong , Nga Pham Hong
Published: December 2014

The inverse problems for determining the meridian shape or varying thickness function of momentless shells of revolution under given loads were concerned in many works [2, 3, 4]. However, for the complexity of loads or configuration of a shell these problems haven' t bee.n solved perfectly because of its mathematical difficulties. In this paper, the problem for determining the thickness function of shells of revolution such as a parabola, sphere arc! under axisymmetrical loads is considered. The general integro-differential equations for determination of the meridian form and shell thickness are obtained. A solution of differential equations by semi-analytical and numerical methods for the thickness is presented. The numerical solutions are given for the parabola under external pressure, the sphere immerged in the fluid and the sphere arc. Obtained results may be used in the thin shell design.

Generally displacement models are used in most usual problems. Under certain material conditions, such elements may provide inaccurate results and exhibit slow convergence. Locking phenomena are the cause of these problems and this situation could limit the computation of many kinds of structures. This paper presents a deep beam element based upon mixed formulation, which may illuminate these locking phenomena.
Using metis model to solve the torsion problem of a prismatic bar
Authors: Duong Nguyen Tien , Hung Nguyen Dang
Published: December 2014

Based on Lekhnitskiis elasticity theory [1], the formulae of generalized plane strain state for the torsion problem of a prismatic bar are established. By this way, this problem in 3 dimensions (3D) is transformed into the problem in 2.5D. Metis models [3] constitute a bridge between the classical models in one field and the hybrid models in two fields. They have the advantage properties of two parents: the dual and monotonous properties of the pure models and the fast convergence of hybrid models. This paper uses the metis displacement model to solve the torsion problem of a prismatic bar after transform this problem from 3D into 2.5D. The agreement of the results in this method with those in exact solution by the analytical method indicated the exactitude of this new model.

This paper deals with a solution for the problem of full shaking force and shaking moment balancing of spatial multi body systems with open kinematic chains. Firstly, the general conditions for complete dynamic balancing of spatial multibody systems are formulated. These include formulae for complete elimination of the resultant inertia force and inertia couple caused by all moving bodies. In the following example, the equations of complete shaking force and shaking moment balancing of a nine-bar direct drive manipulator are given.

Published: December 2014

Este estudo analisa a ludicidade como forma de instrumento na educação e seus efeitos no desenvolvimento das pessoas portadoras de necessidades especiais (PNE’s) na Escola Viva, localizada no município do Natal – RN. Nessa perspectiva, a ludicidade é manifestada no instante em que o lazer estabelece uma sensação de completude, despertando no indivíduo o desejo de continuar a desenvolver atividades que lhe proporcionam prazer. Essa Escola desenvolve suas atividades a partir do lúdico, comprovando que a associação “pedagogia x lúdico” tende a obter bons resultados no desenvolvimento físico-psíquico dos PNE’s. A metodologia utilizada foi o estudo de caso, na qual buscou uma relação estreita com a realidade dos alunos portadores de necessidades especiais, através de entrevistas abertas aos educadores e diretores e ainda aos próprios

alunos no decorrer das atividades. O estudo fornece subsídios para explorar a sensibilidade dos mesmos, liberando-os da rotulação que são “incapazes” de aprender e produzir;

procura-se demonstrar que apesar destes alunos serem PNE’s, eles são capazes de aprimorar seus conhecimentos, sendo, o lúdico, ferramenta indispensável nesta atividade,

considerando que o mesmo, contribui para as manifestações na vida sociocultural de cada PNE.

O presente artigo tem como objetivo analisar a manifestação do fenômeno lúdico nos adultos, que freqüentam o Clube dos Empregados da Petrobrás em Natal/RN. Tal estudo está pautado sob a concepção e perspectiva do lúdico, enquanto fenômeno social. Para se atingir o objetivo utilizou-se uma metodologia caracterizada como qualitativa, sendo,

também, do tipo exploratória. Os dados foram coletados, através de diversas visitas ao local, durante o mês de maio de 2003, dentre as quais foram utilizados questionários de

entrevistas com o dirigente da Instituição e os com usuários do Clube, além de observação não-participante a qual utilizou-se de métodos descritivos visando colher detalhadamente

as características do objeto em estudo. Os resultados obtidos vieram evidenciar e dar veracidade às afirmações feitas pelos estudiosos do lazer, de que o ser humano, à medida

que vai se tornando adulto deixa para trás o significado do lúdico, devido ao uso da racionalidade exacerbada e, também, por causa das convenções impostas pela sociedade.

Terminal 3 roof design and construction at Shenzhen Bao'an international airport, China
Authors: Wells Matthew
Published: December 2014

A combination of Italian design flair, German engineering and Chinese fabrication skill has delivered one of the world's most dramatic-looking airport terminals in just 6 years. The £600 million Shenzhen Bao'an airport Terminal 3 near Hong Kong went from a design competition in 2008 to a 45-million-passengers-a-year terminal in 2013. Looking like a cross between a manta ray and a plane, the entire 450 000 m2 building is skinned in a curving honeycombed space-frame roof. This paper focuses on the design and construction of the 1·2 km long roof structure, which includes conical disc springs to control thermal and seismic movements. Extensive use was made of digital engineering tools to define, analyse and fabricate the frame and cladding. This, together with development of practical and economic construction methods, helped achieve the bold architectural vision in a relatively short time.
Nyelvértés és nyelvhasználat

Tanulmányom a mai ifjúság, ezen belül is a magyar nyelvet majd hivatásszerűen, mesterségük legfőbb alapjaként használó óvodapedagógus-hallgatók nyelvi sajátosságait érinti. A feldolgozáshoz több kérdés is felmerül: hogyan alakul és milyen hatásokra ma az anyanyelvünk? Ez miként jelentkezik a diáknyelvben? Maguk a hallgatók hogyan értékelik mostani nyelvhasználatukat, és meg akarják-e változtatni azt az egyetemi évek után? Értik-e a nyelvet, amit használnak? Érzik-e a felelősséget, vállalják-e a pedagógusi mintát hivatásukban, az anyanyelv terén is? A leegyszerűsített válasz: igen. Igen, a hallgatók egyaránt érzik a felelősséget nyelvük és leendő növendékeik iránt. Ez már önmagában is örömteli megállapítás a különböző, nyelvpusztulást is vizionáló jóslatok után. Az arányok még megnyugtatóbbak, ahogy kiderül a tanulmányból.
