Abstract
Exfoliated organo-montmorillonite (O-Mt) layers were successfully encapsulated in a terpolymer microsphere (PAAA) of acrylamide (AM)/acrylic acid (AA)/2-acrylamido-2-methylpropanesulfonic acid (AMPS) via in situ inverse suspension polymerization, with the aid of the organic modification by cetyltrimethylammonium bromide (CTAB) and sodium lauryl sulfonate (SLS). The chemical structure and properties of the Mt were characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA), which showed that SLS molecules successfully intercalated Mt interlayers and enhanced the thermostability of Mt. The microsphere morphologies of the polymer and its nanocomposites were detected by scanning electron microscopy (SEM). The results of X-ray diffraction (XRD) and transmission electron microscopy (TEM) confirmed that the exfoliated O-Mt dispersed in the polymer matrix. The introduction of well-dispersed O-Mt layers significantly enhanced the comprehensive performance of these microspheres, including thermostability and plugging properties. The T
max of PAAA/1.5 wt.% O-Mt nanocomposite is increased by 46°C compared to the pure terpolymer. The plugging rate of PAAA/2.0 wt.% O-Mt reached up to 85.8%. Therefore, these selected nanocomposite microspheres can provide an effective plugging in the high-permeability layers.
A new method to calculate the surface haze

Published: March 2020

Abstract
Haze (H) is not an accumulative property based on the addition of internal haze (H
i) and surface haze (H
s) parameters, though the relation (H
s = H − H
i) is widely accepted and used nowadays in research and development of plastic films. To evaluate the correct relation, the analytical relation between the total haze (H) and the haze of a single film (h
i) in the film superposition model was firstly concluded, which is 1 − H is equal to the product of 1 − h
i of every single film. This relation was validated by the experimental results using thin films of different kinds of polymers with different hazes. Based on this relation, the expression of surface haze was concluded. When the two surfaces of a film were the same, the haze of the single surface

Published: March 2020

Abstract
Aqueous solution of pH indicator dye tetrabromophenolphthalein ethyl ester containing chloral hydrate was studied for its possibility to be used as a liquid dosimeter. The useful measuring range was found to be (0.5–2 kGy) depending on the concentration of both dye and chloral hydrate added. The system has good stability before and after irradiation under different storage conditions. A comparison study between direct irradiation of the dye containing chloral hydrate and indirect method that executed through avoiding exposure of the dye to irradiation and irradiate the chloral hydrate only followed by outputs for interaction with dye was investigated seeking to extend the dose range up to 5 kGy.
Erklärungsmodelle und Erklärungskonzepte in der sportsoziologischen Forschung: Eine verdrängte Herausforderung?
Authors: Bachleitner Reinhard , Weichbold Martin 
Published: March 2020

Zusammenfassung
Eine Analyse empirisch ausgerichteter Beiträge zu sportsoziologischen Themen und Fragestellungen in der vorliegenden Zeitschrift zeigt, dass gängige sozialwissenschaftliche Erklärungsmodelle bzw. Erklärungsansätze selten zum Einsatz gelangen. Es dominiert meist eine beschreibende und verstehende Methodologie. Dies führt u. a. zu einem Defizit von Erklärungswissen und in Folge wohl auch zu einer verlangsamten Theoriefundierung innerhalb der Sportsoziologie. Um die „erklärende Soziologie“ zu forcieren, werden die aktuell in der Soziologie detailreich und auch kontrovers diskutierten methodischen Erklärungsmodelle und Ansätze einschließlich ihrer Voraussetzungsbedingungen skizzierend dargestellt. Dies geschieht in der Hoffnung, die methodologische Anwendungslücke zu minimieren, da eine auf Erkenntniszuwächse ausgerichtete Sportsoziologie nicht auf eine kriterienorientierte Methodologie verzichten sollte.

Published: March 2020

Gastrointestinal tract is uncommon location for lipomas. If present, 90% are seen submucosally and 10% in subserosal location. Mostly located in the colon, but they can be found in the esophagus, small intestine, and rarely in the stomach. The vast majority of cases with intestinal lipomatosis are usually asymptomatic and some of the cases present with intermittent obstruction, colonic perforation and rarely intussusception. A 20 year male presented in emergency department with history pain in abdomen 15 days back, progressively increasing in intensity and no passage of stool from 4 days. On the basis of history, examination and computed tomography scan of abdomen, possible diagnosis of ileoileal intussusception was made. Patient was admitted in emergency department of surgery and planned for surgery and exploratory laparotomy with resection of ileum 5 cm on both sides was done. A growth was seen in ileal intussusceptum area within 5cm margin and sent for histopathological examination to the department of pathology. On histopathologic examination, a diagnosis of lipoma was made. Lipomas are benign tumours with no risk of recurrence. They should always be kept in the differential diagnosis of sessile polypoid lesions. Surgery is usually curative.

Relevance. In connection with the annual epiphytotic development of peronosporosis (Pseudoperonospora cubensis(Berk. and Curt.) Rostow. on cucumber and the absence varieties immune to this disease, it is advisable to create and cultivate precocious varieties and hybrids that can form the main part of the yield before the period of mass spread of the disease. In order to rationally use the cucumber gene pool long-term research of the world collection is carried out to search of sources of yield, precocity and resistance to peronosporosis.Material and methods. The studies were conducted at Volgograd Experimental Station of VIR (Volgograd province). The research material was 370 cucumber accessions from the world collection of VIR. Evaluation of accessions on a complex of signs was carried out according to methodical guidelines of VIR.Results and conclusions. Long-term study of cucumber accessions of various geographical origin showed that the duration of the interphase period "mass seedlings - the first harvest of fruits" did not differ significantly in samples of different geographical groups, most of them belong to the early ripening. It was found that the duration of the fruiting period depended on the degree of resistance of plants to peronosporosis: the higher the resistance of the variety or hybrid, the longer the fruiting period. A number of precocious, yielding hybrids and varieties, as well as samples with a long period of fruiting and relative resistance to peronosporosis, were allocated. The perspective material for the decision of separate problems in breeding of a cucumber is recommended.

Relevance. The evaluation of adaptive ability of varieties is an actual direction in selection. Phenotypic plasticity of legume crops, in particular green bean, in Siberian region has not been studied enough. There is a need to evaluate grade samples for adaptability and stability, as highly and medium adaptive varieties can realize their genetic potential of productivity in extreme continental climate of Western Siberia.Materials and methods. On the basis Department of Selection, Genetics and Forestry, Novosibirsk State Agrarian University (2015-2019), long-term evaluation of grade samples of green bean of different ecological and geographical origin with a bush type of growth was carried out. Of particular interest are signs that have a significant impact on crop productivity. The signs were studied: number of beans on plant, weight of beans from plant, weight of one bean, yield capacity. The objective of the study is to evaluate the adaptive ability and stability of common bean varieties in the conditions of Siberian region.Results. The conditions of Western Siberia are suitable for cultivating vegetable beans on a green spatula and seeds. It has been established that, based on the weight of one bean, the coefficient of variation has a negative value. This indicates a low variability of the trait depending on the natural and climatic conditions, which allows selection of breeding valuable varieties for this parameter. As a result of the study, 6 genotypes of the crop, combining high productivity and environmental resistance, were selected. It was established that varieties Veronika and Darina can be referred to non-plastic samples. Samples could diversify breeding material of the crop and show the value according to specific features in edaphic-climatic conditions of Western Siberia.

This article discusses how the splinter movements in Indonesia, namely LDII (Lembaga Dakwah Islam Indonesia), MTA (Majlis Tafsir Al Quran) and JMI (Jam'iyyatul Islamiyah) can survive and develop against two constraints that are the state and Islamic orthodox group. The methods of this research-based article are both library and field research. This article uses comparative analysis from the three movements include their adaptive means to the social and political milieu in Indonesia. The movements start to grow in the 1970'. In New Order Era (1966-1998), under Suharto authoritarian regime, these movements use the state approach by joining Golkar, government political party, and help the party to win general elections. However, in the 1990 era, when Suharto starts to embrace the orthodox group, government protection to those religious groups is not enough to withstand the heretical issues that have already spread in public. The issues lead to physical persecution from the mass to these movements. Thus, the only way to survive from that conditions, the three movements start to make an approach to orthodox groups, especially MUI (Majlis Ulama Indonesia) the mainstream group representative such as NU (Nahdlatul Ulama) and Muhammadiyah two biggest Islamic groups in Indonesia, by making dialogues and complying the Islamic mainstream standards issued by MUI.

The gender gap between man and women participation in Science, Technology, Engineering and Mathematics (STEM) is regrettably universal, and generally unacceptably broad. In addition, this gap is particularly noticeable in the Electrical Engineering and Computer Engineering (EECS) careers. Several international organizations and universities in North America, Europe and Latin America have designed programs to address this important problem, showing varying degrees of success. In many of these programs the idea is to work with high school girls, seeking to bring them key knowledge of the disciplines of STEM and encourage them to choose careers in the area. Among other activities, these programs offer presentations, talks, or short courses in a given period at the university itself, taught by women teachers in the area applying the role model approach. This article presents the experience of the Facultad de Ingenier ??a (School of
Engineering) of the Universidad de la Rep ?ublica, Uruguay, on the occasion of the Girls in Information and Communication Technologies (ICT) day. In particular, workshops for robotics, circuits and maps making were held for high school girls as a way to promote ICT careers in Uruguay.
La (méta)génomique des microorganismes du rumen et ses applications à la production des ruminants
Authors: MORGAVI D. , KELLY W.J. , JANSSEN P.H. , ATTWOOD G.T. 
Published: March 2020

La viande et le lait produits par les ruminants sont d'importants produits agricoles qui représentent une source importante de protéines pour les humains. La production des ruminants a une valeur économique considérable et un impact sur la sécurité alimentaire de nombreuses régions du monde. Cependant, le secteur fait face à des défis majeurs en raison de la diminution des ressources naturelles et de la conséquente hausse des prix, mais également en raison de la prise de conscience grandissante de l'empreinte écologique laissée par les ruminants d'élevage. Une particularité des ruminants est la digestion prégastrique des aliments par les microbes du rumen. Une meilleure connaissance du microbiome du rumen et de ses fonctions aura pour conséquence une amélioration de l'efficacité de la digestion des aliments et une réduction de la production de méthane entérique, contribuant ainsi à relever les défis de la durabilité. Le progrès des technologies de séquençage d'ADN et de la bioinformatique accroît notre connaissance des écosystèmes microbiens complexes, y compris du tractus gastro-intestinal des mammifères. L'application de ces techniques à l'écosystème du rumen a permis d'étudier la diversité microbienne sous différentes conditions alimentaires et de production. Par ailleurs, le séquençage des génomes de différentes espèces bactériennes et d’archées isolées du rumen fournit des informations détaillées sur leur physiologie. La métagénomique, utilisée principalement pour comprendre les mécanismes enzymatiques impliqués dans la dégradation des polyosides structurels des végétaux, commence à offrir de nouvelles connaissances en permettant de contourner les limitations imposées par la culture des espèces microbiennes et ainsi de permettre l’accès à la totalité de la communauté. Ces approches permettent non seulement de caractériser la structure de la communauté microbienne du rumen, mais aussi d'établir un lien entre celle-ci et les fonctions du microbiome du rumen. Les premiers résultats obtenus grâce à ces technologies à haut débit ont également montré que le microbiome du rumen est bien plus complexe et diversifié que le caecum humain. Par conséquent, le catalogage de ses gènes exigera des efforts de séquençage et bioinformatiques considérables, mais constitue néanmoins un objectif réaliste. Un catalogue des gènes microbiens du rumen est nécessaire pour comprendre la fonction du microbiome et son interaction avec l'animal hôte et ses aliments. De plus, il fournira une base pour les modèles d'intégration microbiome-hôte et bénéficiera aux stratégies cherchant à diminuer l'action polluantes des ruminants et à les rendre plus robustes et rentables.

La démocratisation des outils de la génomique et plus particulièrement du séquençage à haut débit a permis le séquençage du génome du canard commun. Des projets complémentaires sont déjà initiés pour prolonger et exploiter au mieux ces premiers acquis. En tout premier lieu, il s’agit de poursuivre la description de la structure du génome et d’en exploiter les connaissances : cartes d’hybrides irradiés pour ordonner la séquence le long des chromosomes ; génomique comparée avec le génome de la poule pour bénéficier des connaissances sur ce génome modèle ; recherche de SNP (Single Nucleotide Polymorphism) pour les études et la gestion de populations ; carte génétique pour la détection des QTL (Quantitative Trait Locus). La première détection de QTL influençant les performances du mulard, réalisée à l’aide de marqueurs microsatellites chez la cane commune, sera complétée par une seconde étude utilisant des marqueurs SNP développés spécifiquement et permettant une bien meilleure couverture du génome. Par ailleurs, il est important de réaliser une annotation fonctionnelle du génome, ce qui peut être abordé par le séquençage de transcrits. A terme, le génome annoté sera utilisé pour analyser son expression dans différents tissus et/ou conditions d’élevage, la connaissance des modèles de transcrits et de protéines facilitant les études en transcriptomique et protéomique. Le canard mulard, produit du croisement de la cane commune avec le canard de Barbarie, devra également être étudié en raison de son intérêt agronomique, lié à ses performances exceptionnelles dans la filière des palmipèdes gras.
