Published: September 2019

Background

There is increasing requests of Vitamin D test in many clinical settings in recent years. However, immunoassay performance is still a controversial topic. Several diagnostic manufacturers have launched automated 25-hydroxyvitamin D (25-OH D) immunoassays in the past decade. We compared the performance of Abbott Architect 25-OH D Vitamin immunoassay with liquid chromatography-tandem mass spectrometry systems (LC-MS/MS) to evaluate immunoassay performance, especially in deficient groups.

Methods

Eighty human serum samples were analyzed with Architect 25-OH D vitamin kit (Abbott Diagnostics, Lake Forest, IL, USA) and LC-MS/MS systems (Zivak Technology, Istanbul, Turkey). The results of the immunoassay method were compared with the LC-MS/MS using Passing-Bablok regression analysis, Bland-Altman plots and correlation coefficient analysis. We also evaluated results in four levels of D vitamin as a severe deficiency, deficiency, insufficiency, and sufficiency.

Results

Architect showed 9.59% bias from LC-MS/MS with smaller mean. Passing-Bablok regression analysis demonstrated the value of 0.95 slope and had a constant bias with an intercept value of -4.25. Concordance correlation coefficient showed moderate agreement with the value of 0.918 (95% CI 0.878–0.945). Two methods revealed good interrater agreement (kappa = 0.738). While the smallest bias determined in deficiency (9.95%) group, the biggest was in insufficiency (15.15%).

Conclusions

Architect 25-OH D vitamin immunoassay can be used in routine measurements but had potential misclassification of vitamin D status in insufficient and deficient groups. Although there are recent standardization attempts in 25-OH D measurements, clinical laboratories must be aware of this method.
Connecting Remote C–H Bond Functionalization and Decarboxylative Coupling Using Simple Amines
Authors: de Azambuja Francisco , Yang Ming-Hsiu , Bruecker Alexander , Cheong Paul , Altman Ryan
Published: September 2019

The manuscript describes a Pd-catalyzed reaction of benzylic electrophiles that gives para-substituted arene products. Mechanistic studies suggest a mechanism involving a dearomative C–C bond-forming step, followed by base-mediated rearomatization. This mechanism is uncommon and underappreciated in Pd-catalysis and further exploitation of this mechanism should enable access to other organic molecules.

Published: September 2019

The building of van der Waals heterostructures and the decoration of 2D materials with organic molecules share a common goal: to obtain ultrathin materials with tailored properties. Performing controlled chemistry on van der Waals heterostructures would add an extra level of complexity, providing a pathway towards 2D-2D-0D mixed-dimensional heterostructures. Here we show that thiol-ene-like “click” chemistry can be used to decorate franckeite, a naturally occurring van der Waals heterostructure, with maleimide reagents. ATR-IR and NMR analyses corroborate the Michael addition mechanism via the formation of a S-C covalent bond, while Raman and HR-TEM show that the SnS2-PbS alternating structure of franckeite is preserved, and suggest that SnS2reacts preferentially, which is confirmed through XPS. We illustrate how this methodology can be used to add functional molecular moieties by decorating franckeite with porphyrins. UV-vis-NIR spectroscopy confirms that the chromophore remains operative and shows negligible electronic interactions with franckeite in the ground state, while its fluorescence is strongly quenched upon photoexcitation.
Metalloporphyrins into Mesoporous Photonic Crystals: Towards Nanostructured Sensing Devices
Authors: Caraballo Rolando M. , Onna Diego , Abdala Nicolás López , Soler-Illia Galo J.A.A. , Hamer Mariana
Published: September 2019

Metalloporphyrins are molecules capable of optically sensing targets due to their specific reactivity. Shifts in metalloporphyrins spectra are usually in the order of 30 nm, requiring a spectrophotometer for transducing the analyte concentration. Mesoporous oxide thin films photonic crystals (PC) act as optical filters, while their pores can host molecular moieties. In this work used a metalloporphyrin, MnIII meso-tetra(N-methyl-4-pyridyl) porphyrin (MP), to add a recognition functionality to a PC and, at the same time, retain their pore network, in order to develop a versatile and portable sensing device for volatile amines. The hybrid material MP@PC was prepared by immersion of the PC, synthesized from two mesoporous oxides with different refractive index, in an MP solution. The system was characterized by UV-Vis absorption and FTIR spectroscopies, and SEM microscopy. Sensing of small molecules was tested using ethylenediamine (EDA) as a volatile amine model, showing an absorbance increase in the PC spectral window with promising analytical parameters. The hybrid material presents enhanced sensing capabilities compared to MP or PC alone. A prototype device was built, aiming for a future design of simple, low-cost equipment, with a light emitting diode and a light-dependent resistor, including the MP@PC sensor. The device is capable of sensing with only 1.52 μg of MP on a 1 cm2 glass slide and it is easily prepared and showed a very small detection limit.

Este trabajo se ajusta para la localidad de Babahoyo, en la provincia de Los Ríos (Ecuador), con el objetivo de diseñar un sistema de producción de arroz que haga sustentable a este monocultivo en Babahoyo y establecer indicadores para la evaluación de la sustentabilidad de este sistema de producción de arroz. Se procederá bajo el siguiente esquema metodológico: con el diseño de los cercos forestales propuestos se podrá establecer un sistema de producción de arroz en donde también se realizaría rotación de cultivos. Los cercos forestales se conformarán por la siembra alternada de inga (Inga edulis Martius), guayacán (Guaiacum sanctum L.) y mango (Manguifera indica), sobre los muros perimetrales de las parcela de arroz, mientras que la rotación de cultivos será entre arroz (Oryza sativa L.) y soya (Glycine max L.), en el año se cultivará arroz en estación húmeda y soya en estación seca. Los resultados serían la transformación del monocultivo de arroz en un Sistema Sustentable de producción de arroz, lo que permitirá al productor arrocero no depender solo de la producción y comercialización de esta gramínea; con la soya y la inga el sistema permitirá también la fijación de nitrógeno en el suelo y por la naturaleza de sus raíces la soya evitará la compactación del suelo. Asimismo, se espera que el sistema agroforestal propuesto contribuya de un modo eficiente a la captura de carbono. En términos fitosanitarios, la rotación de cultivos interrumpirá los ciclos biológicos de las plagas propias de los cultivares.

Authors: Hamdan Rana Khaled , Sarsam Saad Issa
Published: September 2019

Recycling can be considered as one of the measures of sustainable methods. The physical traits of the asphalt mixture under the influence of accelerated aging (Long and Short–Term) for asphalt concrete were assessed. Asphalt cement (40-50), aggregate with 12.5 mm nominal extreme size and limestone dust as filler of the mineral was used for the preparation of asphalt concrete mixture. At the optimum content of the asphalt and asphalt of 0.5 percent below and above the optimum value, specimens were prepared by using Marshall Method. Two types of polymers as recycling agents were used (Polyethylene of Low Density and Crumb Rubber) with (0.5, 1 and 1.5) % by weight of the binder. The indirect tensile test was used for the mixtures at 25 ºC and double punch test at 60 ºC. It was determined that the use of (asphalt binder mixed with rubber) as the agent of recycling showed improved performance than the other kind of recycling agent. The indirect tensile strength at 40 ˚C of the recycled mixture was higher than that the control mixture. Punching shear strength was decreased by 84 %, temperature susceptibility was decreased by 69.6 % and the resistance to moisture damage increases by3.3 % at optimum asphalt content.

En la última década existe un gran debate sobre el impacto que tiene el uso de las Tecnologías de la Información y de la Comunicación (TIC) en el ámbito educativo. La tendencia mediática y el uso masivo de tecnologías (computadores, teléfonos inteligentes, tabletas, PDA, laptops, entre otros) con conexión a Internet, son tendencias que generan cambios en el modo de aprender y acceder al conocimiento en una sociedad digitalizada. El estudio presentado es un diseño de investigación no experimental descriptivo con un enfoque cuantitativo, con una muestra de 121 estudiantes y 29 profesores de área de matemáticas de nivel medio de las unidades educativas de las provincias de Pichincha, Guayas y el Oro; pretende aportar evidencias empíricas sobre el nivel impacto que tiene la integración de las TIC como herramientas para el aprendizaje de la matemática de los estudiantes de educación media. Los resultados muestran que el papel de la tecnología e Internet en el aprendizaje de la matemática pueden generar alguna motivación, no representan para los estudiantes y docentes un factor significativo ni de alto impacto en el aprendizaje de la matemática a largo plazo, no por su uso o acceso a ellas, sino por la falta de competencia para aplicarlas en su aprendizaje.

In vivo Modulatory Effect of Coffee (Coffea canephora var. Robusta) on the Expression Levels of Murine microRNA‐124‐3p Associated with Antioxidant Defenses
Authors: Curti Valeria , Verri Manuela , Baldi Alessandra , Dacrema Marco , Masiello Irene , Dossena Maurizia , Daglia Maria
Published: September 2019

Antioxidant activity is one of the most studied properties of coffee as a beverage, and is mainly ascribed to its polyphenol content, although there is limited scientific literature regarding its mechanism of action at the molecular level. In recent years, epigenetics has been featured as a promising approach in many studies for explaining the mechanisms of action involved in its effects on health exerted by foods and food components. To investigate such an epigenetic contribution toward the antioxidant properties of coffee, an in vivo study was performed on healthy C57BL/6 mice fed with a normal diet supplemented with a low‐molecular‐weight (MW) fraction (MW < 3500 Da) obtained from regular and decaffeinated coffee. Regular coffee supplementation induced a downregulation of microRNA‐124‐3p, and its validated target, mRNA coding for glutathione peroxidase (GPX), was upregulated. Decaffeinated coffee was not found to induce any significant changes in the expression levels of microRNA‐124‐3p and its validated target mRNA. It may be concluded from the results that regular intake of coffee exerts its antioxidant activity through an epigenetic mechanism of action, at least in part, being able to influence the expression levels on a miRNA and an mRNA involved in antioxidant defenses, with caffeine playing a crucial role.

Troubling Practice: Exploring the Relationship Between Whiteness and Practice-Based Teacher Education in Considering a Raciolinguicized Teacher Subjectivity
Authors: Daniels Julia R. , Varghese Manka
Published: September 2019

In this essay, we argue that teacher education is increasingly marginalizing the relevance of teacher subjectivity and recentering Whiteness, especially in its uptake of practice-based teacher education. Whereas teacher subjectivity has been pushed to the margins of recent conversations about teacher education—and has therefore narrowed our understanding of the ideological and practical affordances and constraints of practice-based teacher education—we show that it must be centered in teacher education and understood as fundamental to all teachers’ embodied practice. We draw from literature exploring critical Whiteness studies, raciolinguistics, poststructural understandings of teacher subjectivity, the experiences of teachers of Color and practice-based teacher education. By showing how a raciolinguicized teacher subjectivity has been marginalized, we simultaneously argue for the centrality of the role of subjectivity in shaping teaching and, therefore, in defining critical dimensions of what and how novice teachers need to learn.

Introducción y objetivos: La introducción de los frutales Euroasiáticos de la familia botánica de las Rosáceas en el noroeste argentino durante el periodo Colonial, dio lugar a procesos de selección cultural y diversificación, siendo reconocidos como cultivos propios por las comunidades locales que habitan en la Quebrada de Humahuaca. El objetivo de este trabajo es presentar la diversidad de etnovariedades de “manzanas” (Malus domestica), sus usos y los atributos localmente percibidos que se emplean para su diferenciación en la comunidad de Ocumazo (Departamento de Humahuaca, Jujuy, Argentina). M&M: La metodología etnobotánica, principalmente de corte cualitativo es la que permitió el desarrollo de este trabajo, el cual se llevó a cabo entre el año 2016-2018. Resultados: Los productores entrevistados (28) establecen la presencia de (15) etnovariedades de “manzana” empleadas en alimentación y para la elaboración de productos muchas veces comercializados localmente. El fruto es el principal órgano vegetal citado para definir los criterios o descriptores culturales empleados para la diferenciación de las etnovariedades. Conclusiones: El uso, la forma de selección, conservación, su consideración como parte de la diversidad de frutas andinas y la presencia en distintas instancias religiosas y de celebración, definen el papel relevante de este cultivo introducido para el poblador local, que a su vez le permite promover la conservación de actividades económicas principales como las agrícolas y su autonomía alimentaria.
Autistic peer to peer information transfer is highly effective.

Please do not cite this preprint. Effective information transfer requires social communication skills. As autism is defined by social communication deficits, we might expect that information transfer between autistic people would be particularly deficient. We test this hypothesis by examining information transfer between autistic adults, neurotypical adults, and mixed autistic-with-neurotypical pairs.Initial participants were told a story which they recounted to a second participant, who recounted the story to a third participant, and so on, along a “diffusion chain” of 8 participants (n=72).We found a significantly steeper decline in detail retention in the mixed chains, while autistic chains did not significantly differ from neurotypical chains. Participant rapport ratings revealed significantly lower scores for mixed chains.These results challenge the diagnostic criterion that autistic people lack the skills to interact successfully. Rather, autistic people effectively share information with each other. Information transfer selectively degrades more quickly in autistic-with-neurotypical dyads, in parallel with a reduction in rapport.

Vortex cooled air turning of induction-hardened raceway on the wind turbine-bearing ring
Authors: Bošnjaković Mladen , Maglić Olivera , Moškun Dragomir , Crnac Zoran
Published: September 2019

In the turning process of hard materials with CBN cutting inserts, metalworking fluid is not advisable as it results in poorer quality of finished surface and shortening of the tool life. Dry machining, otherwise, develops excessive heat, residual stresses in the workpiece material due to thermal stress, and therefore causes possible problems of achieving tolerances on larger workpieces. During the dry turning of induction hardened raceway on the wind turbine-bearing ring of 1500 mm in diameter, problems with achieving tolerances occurred. The vortex-cooled air implementation during turning resulted in achieving designing tolerances of the workpiece, with better surface roughness and with less tool wear. The result was 50% lower cost of cutting inserts and small operating costs associated with air consumption. The vortex-cooled air implementation makes it possible to extend the tool life of CBN cutting inserts and thus higher cost-effectiveness of machining.
A Pilot Microbiota Study in Parkinson’s Disease Patients versus Control Subjects, and Effects of FTY720 and FTY720-Mitoxy Therapies in Parkinsonian and Multiple System Atrophy Mouse Models
Authors: Vidal-Martinez Guadalupe , Chin Brandon , Camarillo Cynthia , Herrera Gloria V. , Yang Barbara , Sarosiek Irene , Perez Ruth G.
Published: September 2019

Background:

Parkinson’s disease (PD) and multiple system atrophy (MSA) patients often suffer from gastrointestinal (GI) dysfunction and GI dysbiosis (microbial imbalance). GI dysfunction also occurs in mouse models of PD and MSA.

Objectives:

To assess gut dysfunction and dysbiosis in PD subjects as compared to controls, identify potential shared microbial taxa in humans and mouse models of PD and MSA, and to assess the effects of potential therapies on mouse GI microbiota.

Methods:

In this human pilot study, GI function was assessed by fecal consistency/frequency measured using the Bristol Stool Form Scale and GI transit time assessed using Sitzmarks pills and abdominal radiology. Human and mouse microbiota were analyzed by extracting fecal genomic DNA followed by 16S rRNA sequencing.

Results:

In our PD patients genera Akkermansia significantly increased while a trend toward increased Bifidobacterium and decreased Prevotella was observed. Families Bacteroidaceae and Lachnospiraceae and genera Prevotella and Bacteroides were detected in both humans and PD mice, suggesting potential shared biomarkers. In mice treated with the approved multiple sclerosis drug, FTY720, or with our FTY720-Mitoxy-derivative, we saw that FTY720 had little effect while FTY720-Mitoxy increased beneficial Ruminococcus and decreased Rickenellaceae family.

Conclusion:

Akkermansia and Prevotellaceae data reported by others were replicated in our human pilot study suggesting the use of those taxa as potential biomarkers for PD diagnosis. The effect of FTY720-Mitoxy on taxa Rikenellaceae and Ruminococcus and the relevance of S24-7 await further evaluation. It also remains to be determined if mouse microbiota have predictive power for human subjects.
Intervening Effects of Orthostatic Blood Pressure Change on Subcortical Atrophy and Cognition in De Novo and Drug-Naïve Parkinson’s Disease
Authors: Yoo Sang-Won , Oh Yoon-Sang , Yoo Ji-Yeon , Ryu Dong-Woo , Lee Kwang-Soo , Shin Na-Young , Kim Joong-Seok
Published: September 2019

Background:

Cognitive impairment and cardiovascular dysautonomia are two major non-motor features of Parkinson’s disease (PD). They have been investigated separately and extensively, but their interactive outcomes have rarely been studied.

Objective:

The purpose of this study was to examine the association between central atrophy and cognition and to assess the influence of cardiovascular lability on this association in PD patients.

Methods:

Out of 151 early PD patients, 47 subjects were ultimately enrolled according to our selection criteria. Their cognitive status was examined by comprehensive neuropsychological tests assessing five domains of cognition. Supine and orthostatic blood pressures were recorded during head-up tilt tests, and orthostatic mean arterial pressure change was calculated. Every patient underwent brain magnetic resonance imaging, and intercaudate nucleus ratio was obtained as a central atrophy surrogate marker. The associations and interactions between central atrophy, cognition, and blood pressure variability were analyzed.

Results:

Among 47 subjects, 20 (42.6%) had orthostatic hypotension. Attention/working memory, executive function, and delayed recall were inversely associated with central atrophy ( r = –0.332, p = 0.028; r = –0.314, p = 0.038; r = –0.399, p = 0.024; respectively). In a multiple regression model, only attention/working memory was independently associated with central atrophy when modulated by orthostatic mean arterial pressure change ( p < 0.05).

Conclusion:

This study revealed that cardiovascular dysautonomia interacted with the inverse association between cerebral atrophy and cognition, and it reinforced its relationship. Interaction between these two non-motor features should be kept in mind in clinical practice, particularly in PD patients with co-morbid vascular factors.
Directional weighted spatial fuzzy C-means for segmentation of brain MRI images
Authors: Khan Sajid Ullah , Ullah Imran , Ahmed Imran , Imran Ali , Ullah Najeeb
Published: September 2019

Brain and its structure are extremely complex with deep levels of details. Applying image processing methods of brain image can be very useful in many practical domains. Magnetic Resonance Imaging (MRI) is widely used imaging technique and has particular advantage by possessing the capability of providing highly detailed images of brain soft tissues than any other imaging techniques. The real challenge at hand for researchers is to perform precise segmentation while overcoming the effects of noise and other imaging artifacts like intensity in homogeneity introduced in medical images during image acquisition process. In this research work, a directional weighted optimized Fuzzy C-Means ( dwsFCM) method has been proposed for segmentation of brain MR images. This method works by incorporating the spatial information of the pixels of the images and assigning the directional weights to the neighborhood. In order to validate the proposed segmentation framework, a comprehensive set of experiments have been performed on publically available standard simulated as well as real datasets. The experimental results showed 95% of accuracy and the performance of the proposed segmentation framework is much better and the framework suppress the sufficient amount of noise especially rician noise and reproduce good segmentation by overcoming the effect of intensity in homogeneity.

The mega peripheral metropolis: towards a comprehensive explanation
Authors: Jucá Antonio
Published: September 2019

This paper presents a comprehensive approach for the urbanization process, firstly discussing urban growth in order to perceive how a set of forces of urbanization work together. The analysis presents economic crises and roles of states as central elements through an argumentative discourse, targeting the exam of urban growth in periphery emerging countries. This is an attempt to explain super urban agglomerations in these countries, which often absorb most of the domestic and foreign investments, creating a cycle of growth, either economic or in terms of population, apparently with no control. Yet theoretically, this thinking also discusses possible scenarios of the process over networks of cities in these countries, defining and confining the concept of urban network, as well as other concepts in a critical way.
Direito das Favelas: lineamentos de um conceito

Published: September 2019

O presente artigo integra um esforço de pesquisa, que vem sendo desenvolvido ao cabo de, ao menos, uma década, no sentido de conhecer as favelas – e, de modo mais abrangente, os assentamentos de baixa renda – e suas dinâmicas internas, desde um ponto de vista sociojurídico. Consiste em contribuir, com o olhar e com os instrumentos analíticos do jurista, para o amplo e longo debate a respeito do desenvolvimento, consolidação e requalificação das favelas, tema de interesse seja no Brasil, seja em outras sociedades nacionais. No espaço de que disponho nesse artigo, buscarei conceptualizar a noção-chave que corporifica esse esforço, esclarecendo o que entendo por Direito das Favelas, noção que propusemos e vimos adotando em nossos escritos desde 2007, explicitando os pressupostos e as questões nas quais essa noção se traduz, bem como indicando algumas possíveis ilustrações e aplicações que ela admite. Como resultados, buscaremos apontar o potencial renovador – e ampliador – que este debate possui em relação à teoria jurídica e à teoria social a respeito das favelas, bem como, suas repercussões de ordem teórico-prática, a exemplo de sua potencialidade em contribuir para a reorientação de políticas urbanas comumente aplicadas a esses espaços, como as de urbanização e regularização.

Abstract

The meaning of song and music is different, but copyright literature does not seem to distinguish them. In the library of international law, the term commonly used to refer to a song or music is musical work. The Bern Convention states that one of the protected works is music compositions with or without words. There is no explicit description in the Bern Convention about what musical work really is. However, from the existing provisions it can be concluded that there are two types of music creation that are protected by copyright, namely music with words and music without words. Music with meaningful words is a song whose elements consist of melody, arrangement lyrics, and notation, while music without words is music that only consists of elements of melody, arrangement and notation.

 

Keywords: copyright literature; the Bern Convention; protected works.
Adherence to guidelines on documentation required for registration to London GP practice websites: a mixed-methods cross-sectional study
Authors: Hodson Nathan , Ford Elizabeth , Cooper Maxwell
Published: September 2019

Background

The most common obstacle to registration with a GP practice in the UK is difficulty presenting proof of address. NHS guidelines stipulate that inability to provide ID or proof of address is not reasonable grounds to refuse registration. Practices may ask patients to present ID/proof of address, but need a policy in case patients cannot.

Aim

To find out how many London GP practice websites ask for documentation without a policy for where this cannot be provided and compare how GP practice websites describe the registration process in patient-facing material.

Design and setting

Cross-sectional study of practices from 10 London boroughs (n = 100).

Method

A proforma was piloted and then implemented, recording whether practices ‘demanded’, ‘requested’, or ‘mentioned’ photo ID or proof of address and whether there was a plan for patients without documentation. Text relating to documentation from all 100 practices for registration was subjected to thematic analysis.

Results

Out of 100 practices 75% asked for documentation. The majority of these were ‘demanded’. A plan was included for people without documentation in 12% of practice websites. Five themes emerged from analysis of website content: reassuring people without documentation; diverse requirements between practices; conflating administration and treatment; withholding treatment; and immigration and ethnicity.

Conclusion

Many practice websites breached NHS Standard Operating Principles and possibly the Equalities Act 2010. All practices should create a clear policy for patients who do not have photo ID/proof of address (for example, including a named receptionist), and update their websites accordingly.

Para as análises dos dados, utilizamos o quadro teórico e metodológico Interacionismo Sociodiscursivo, considerando as figuras de ação (BULEA, 2010). Observamos, no discurso dos professores, a explicitação de seus objetivos, a cristalização do agir, a reapropriação da ação e a avaliação de seu trabalho.

O estudo analisa a representação do feminino em Jenyffer Nascimento a partir dos poemas “Antítese” e “Ventre livre”, da antologia Terra Fértil (2014). Objetiva revisar os conceitos de desconstrução, de Jacques Derrida (1973) e gênero, de Judith Butler (2008). Percebeu-se que a escrita da poetisa apresenta a função de dessacralização no sentido de deslocar a lógica estruturada pelo masculino ao representar sua coletividade marginalizada.
Corpo

Partindo da lógica de que as artes do corpo na contemporaneidade têm profunda relação com a inserção do corpo do artista nas proposições de arte, o texto analisa a performance e seus desdobramentos na arte atual: as consequências das práticas corporais nas formas de fruição e comercialização dos trabalhos artísticos e as novas questões levantadas pelos artistas e público das performances; a ausência e a presença de corpos muito além da representação; as novas formas de participação propostas por artistas contemporâneos; a estética relacional com base nas relações de rede inauguradas na década de 1990 com o advento da internet etc.

A produção de lixo eletrônico tem se destacado mundialmente entre os maiores geradores de resíduos da atualidade, além de serem descartados de forma inadequada, impactando o ambiente e a saúde pública, pois apresentam em sua composição diversos metais pesados. O presente trabalho teve como objetivo a produção de BioTv’s Interativas (aquários sustentáveis), por meio da reciclagem do lixo eletrônico (televisores, gabinetes, monitores de computadores ) e de rejeitos de pisos cerâmicos, de forma integrada com a comunidade e estudantes, construindo uma ferramenta de educação ambiental, sendo posteriormente destinadas as instituições parceiras com intuito de trabalhar a interdisciplinaridade, em prol do desenvolvimento sustentável.
A interdisciplinariedade na Educação Ambiental como instrumento para a consolidação do Desenvolvimento Sustentável
Authors: Tagliapietra Odacir Miguel , Carniatto Irene
Published: September 2019

a relação homem/natureza foi se alterando no decorrer dos tempos, inicialmente, existia uma relação harmônica, pois  o ser humano extraia da natureza somente o necessário para sua sobrevivência. Com o aumento da população e os avanços tecnológicos, cada vez mais houve predomínio do homem sobre a natureza gerando desequilíbrio nos ecossistemas. Para reverter esse quadro foram realizadas diversas conferências, encontros e ações visando a busca de um novo modelo de desenvolvimento que minimizasse os impactos socioambientais ocasionados pela racionalidade econômica vigente. A educação ambiental surge como uma tentativa de se desenvolver uma nova mentalidade crítica e reflexiva voltada para a integração das diversas ciências, a partir de uma abordagem interdisciplinar. Esse tipo de interação entre os diversos saberes visa tratar os problemas socioambientais em sua totalidade e complexidade. O conceito sustentabilidade envolve os aspectos econômicos e socioambientais, nesse sentido necessita do envolvimento das diversas ciências numa perspectiva interdisciplinar, possibilitando, desta maneira, o desenvolvimento que atenda todos os aspectos da realidade, mantendo o ambiente natural com todas a sua vitalidade e, um desenvolvimento com equidade e justiça social. O estudo se caracteriza como bibliográfico, tendo como objetivo analisar a importância da interdisciplinaridade para a consolidação do  desenvolvimento sustentável. Como resultado, pode-se concluir que, conforme analisado na literatura pesquisada, o desenvolvimento sustentável somente se efetiva a partir de uma visão sistêmica do desenvolvimento, alicerçado no tripé econômico, social e ambiental e, para isso necessita de uma abordagem interdisciplinar com a contribuição dos diferentes tipos de saberes.
Tswana locatives and their status in the inversion construction
Authors: Creissels Denis
Published: September 2019

Several articles published in the last decade have demonstrated that, in several Sotho-Tswana (S30) and Nguni (S40) languages, locative marking has ceased to be integrated into the noun class system, and preverbal locatives in inversion constructions do not show evidence of being grammatical subjects. Part of the literature on Tswana suggests however that in both respects, Tswana might be different. The present article argues that the locative system of Tswana is in fact not particularly conservative (and is even more innovative than that of the other S30-40 languages), and the preverbal locatives in the inversion construction of Tswana do not show properties that could support analyzing them differently from the preverbal locatives in the other S30-40 languages.
The effect of hydrogen on the properties of polymorphic metals during thermal cycling near the polymorphism temperature
Authors: Karpov V , Nosko O
Published: September 2019

The effect of hydrogen on the numerous properties of metals is known. In general, it is associated with the structure of its atom, which consists of a proton and an electron. Getting into the metal, it turns into an elementary particle, which has its own special properties. The paper considers the case of the interaction of hydrogen with polymorphic metals during their thermal cycling around the temperature of polymorphism. The main metal of this study is iron. It was revealed that during thermocyclic treatment in a hydrogen medium in iron during cooling, the yield strength decreases catastrophically by 3–4 orders of magnitude (up to a certain time, it was considered one order). In the absence of hydrogen (thermal cycling in an inert atmosphere), such changes did not occur. It was determined that when the crystal lattice restructuring from the γ phase to the α phase, the solubility of hydrogen decreases and it accumulates at the transformation boundary. Depending on the process parameters (cooling rate, saturation pressure, overheating temperature, symmetry relatively to the transformation point, etc.), various types of involuntary metal flow can be obtained. Besides the iron, other polymorphic metals - manganese, cobalt, titanium, zirconium - have been investigated. The deformation effect was observed only for manganese. Cobalt, due to another mechanism of polymorphic transformation, can not be deformed. Hydride-forming metals under normal conditions of cycling are severely cracked (the formation of hydrides), their small deformation is possible under very low hydrogen pressure. The reason for the formation of such properties is the creation of a special zone on the boundary of two phases – the H-layer. The concentration of hydrogen in the H-layer can reach tens of atomic percentages. This is confirmed by numerous experiments on fixing a new phase (N-martensite) and change the physical and mechanical properties of iron. In the deformation process, protons actively interact with defects in the lattice, which causes the pores formation inside the metal. These studies were awarded a diploma for the opening No. 313 authors V.Yu. Karpov and V.I Shapovalov.
Functional dependencies between sample properties from structured molding and core mixtures

Published: September 2019

Article is devoted to functional dependencies between the parameters of structured molding and core mixtures establishment, which are determined on samples using standard and generally accepted methods. The aim of the work is properties of structured molding and core mixtures for disposable casting molds predicting accuracy improvement.To establish the general structure of proposed dependences, dimensional analysis -theorem has been used. According to theoretical studies results, functional dependencies between flaking, brittleness, strength, castings from castings molds and cores knockout work and number of parameters and properties of structured molding and core mixtures were established for the first time. These dependencies implementation will improve analysis and prediction of number of properties levels accuracy, as well as accelerate compositions of molding and core mixtures optimizing process when used in foundries. Ultimately, accuracy increasing in prediction of structured mixtures properties will entail castings quality improvement and level of cast parts nonconformance decreasing. It has been noted that, in first approximation, it’s permissible to estimate mixtures knockout ability according to their residual strength values.

Despite considerable reform activity surrounding K-12 education over the last 20 years, racialand socioeconomic disparities among students who achieve at advanced levels have receivedlittle attention. This study examined how excellence gaps, defined as differences in performanceat the 90th percentile of subgroups, change over time and their potential antecedents. Weanalyzed Measure of Academic Progress achievement data in reading and mathematics from acohort of approximately 60,000 students from third to fifth grade in 742 elementary schools.Multilevel modeling results indicate Black/Hispanic and White/Asian excellence gaps wererelatively stable in reading. However, excellence gaps in mathematics increased during theschool year and across time, and higher achieving schools demonstrated larger excellence gapsthan lower achieving schools.
