Researches of a branch composition and firing atmosphere influence on structure and properties of pressed alumina-chromia-zirconium silicate refractories with 60 % Cr2O3 content were carried out. The optimal branch composition which after firing in oxidizing atmosphere provides obtaining of samples with open porosity 24.8 %, apparent density 3.46 g/cm3, cold crushing strength 78 N/mm2 and thermal shock resistance by 950 ºС — water — 7 thermal cycles was established. The phase composition of samples was determined. It has been shown that, firing in a reducing atmosphere, as well as titanium oxide addition, have no significant effect on samples properties.

Corrosion resistance comparative researches of alumina-chromia-zirconium silicate refractories with 60 % Cr2O3 content and refractory brand KHTSS-30 with 30 % Cr2O3 content to glass «E» and basalt melts by crucible method at a temperature of 1580 °C with an exposure time of 8 hours were carried out. It has been established that, glass «E» and basalt impregnate refractories, moreover for samples with the developed optimal composition the impregnation depth was the smallest in comparison with samples of other compositions. The corrosion mechanism has been established, which consists in the penetration of glass «E» and basalt melts into refractory with further dissolution of corundum grains in them. Sintered Cr2O3 and solid solutions based on it in the composition of samples prevent corrosion, reducing the interaction area of melts with corundum grains, and when exposed to basalt melt, also forming spinelid with its components, which slows down further penetration of melt into refractory structure, thereby reducing its corrosive effect on the refractory.

Based on the obtained results, a technology of a new domestic type of product (alumina-chromia-zirconium silicate refractories with 60 % Cr2O3 content manufactured by semi-dry pressing method) was developed.

Effect investigation of an addition amount of spherical alumina on the properties of ramming mullite-corundum mixes of the MMK-90 (on a binder of an aqueous solution of orthophosphoric acid) and MMKPBF (with a MgO addition on a borophosphate binder) brands, as well as samples from them, have been carried out.

As a result of the carried out studies, it was found that the use of an optimal amount (4 %) of spherical alumina in the composition of ramming mullite-corundum mixes provides an increase in by 30 % in the cold crushing strength of samples made from them, fired at a temperature of 1580 °C, while maintaining at sufficiently high level indicators of their thermal shock resistance and slag resistance. The indicated alumina use in the composition of the MMK-90 mix during high-temperature firing of samples leads to an intensification of the mullite synthesis process. In fired samples from the MMKPBF mix, the spherical alumina forms a dense intergrowth of "felt-like" structure, which reinforces the structure, increasing the strength and thermal shock resistance of the samples.

Indicators of physical and chemical properties of ramming mullite-corundum mixes of improved composition and samples made from them (for MMK-90 and MMKPBF mixes, respectively): chemical composition, wt. %: Al2O3 — not less than 90.0 and 85.0; SiO2 — within 3.2-5.0 and no more than 2.5; Fe2O3 — no more than 1.0 and 0.6; P2O5 — in the range of 2.5-3.5 and 0.5-1.0; grain size composition, mm — 3-0; cold crushing strength after firing at a temperature of 1580 °С — 110 and 70 N/mm2; thermal shock resistance — > 20 thermal cycles 950 °С — water.

Ramming mullite-corundum mixes of improved composition are recommended for use in various heating units with high specific mechanical loads on the lining.

The predicted service temperatures and eutectic compositions of the polycomponent sections of the CaO—Al2O3—Fe2O3—Cr2O3 system were calculated and evaluated. According to the results of geometrical topological studies of this system, the CaAl2O4—CaFe2O4—CaCr2O4—Ca4Al2Fe2O10 tetrahedron has the largest relative volume and the smallest degree of asymmetry. However, the composition of this tetrahedron includes two compounds that do not have hydraulic activity; this will adversely affect the cement strength. Presence of CaFe2O4 will significantly reduce the composition melting point, that why the CaAl2O4—Ca12Al7O33—CaCr2O4—Ca4Al2F2O10 tetrahedron is of more interest. The calculations result of temperatures and eutectic compositions of triple and tetra-component sections of the CaAl2O4—Ca12Al7O33—CaCr2O4—Ca4Al2F2O10 region of the CaO—Al2O3—Fe2O3—Cr2O3 system are presented. The phases that make up this tetrahedron are highly likely to exist in the CaO—Al2O3—Fe2O3—Cr2O3 system, which will allow us to develop a stable technology for the oil-well cementing materials based on calcium-ferro-alumina chromate cement without special techniques for ensuring high accuracy of the starting components dosage. The paper presents graphic images of the liquidus surface of polycomponent sections of optimal region of system. Selected areas are the most suitable for producing oil-well binding materials with an elevated temperature in application. It was found that, composite materials based on this system can be used at temperatures above 1350 °C. Based on the analysis of temperatures and eutectics compositions of polycomponent section, the use of rational area compositions for producing high-temperature resisting oil-well cement has been proved.

Banking system, Institutional quality, and Economic growth: Panel data analysis on a sample of countries in the MENA region
Authors: Jamel Lamia
Published: February 2021

The nexus among financial development and economic growth has long remained a subject matter of considerable debate in the financial and economic literature. This article examines the relationships between financial development, institutions, and economic growth. This indicates that the marginal effect of financial development on economic growth depends on the quality of institutions. To do so, we employ a panel data of 14 MENA countries during the period of study from 2008 to 2019. For the econometric methodology, we use fixed and random effects models. To choose between fixed effects and random effects, we employ the Hausman test. Based on the empirical findings, we demonstrate that financial development has a positive effect on economic growth. Furthermore, we have observed that institutional quality seems to be a necessary complement to financial development. Consequently, it is important to implement policies leading to the deepening of financial systems, through a including a solid institutional framework. Thus, by promoting such development and better institutional quality, economic growth will thus be accelerated.

Authors: Jesus Daiana Souza de , Silva Jonas Santos
Published: February 2021

O objetivo deste trabalho foi apresentar os principais fatores que influenciam a variação radial da madeira de eucalipto e avaliar o quanto esta característica pode influenciar as propriedades desse material. A variabilidade encontrada dentro de uma árvore individual é acarretada pelas mudanças sofridas pelo câmbio, durante o envelhecimento, e as modificações impostas pelas condições ambientais. A heterogeneidade do material causa uma série de transtornos para a indústria de transformação e processamento. A descontinuidade física da madeira ocorre em razão de vários fatores, como as características intrínsecas à própria espécie, os tratos silviculturais e, principalmente, a constituição e organização anatômica da espécie.

O objetivo deste trabalho foi comparar casos de intoxicações por agrotóxicos, produção agrícola e perfil sociodemográfico, no período de 2007 a 2017, entre os estados Acre e Rondônia. O estudo é descritivo, com levantamento de dados por meio de consultas à base de dados do Sistema de Informação de Agravos e Notificação, ao Instituto Brasileiro de Geografia e Estatística (IBGE) e ao Ministério da Agricultura Pecuária e Abastecimento (MAPA). Utilizou-se a plataforma OpenEpin para transcrição de dados em proporção e IC 95%. Acre e Rondônia são respectivamente o 24.º e o 16.º colocados entre os estados que comercializam agrotóxicos. Quanto ao uso de agroquímicos por área plantada, Rondônia está em 5.º lugar, e o Acre, em 19º. O predomínio da agricultura familiar é notório nos estados. As maiores incidências de notificações de intoxicações se deram como resultado de uso de agrotóxicos agrícolas, com maior ocorrência em pessoas do sexo masculino. Diante do uso indiscriminado desses produtos agrotóxicos, detecta-se a necessidade de uma fiscalização e controle mais eficazes, promoção de políticas públicas para acompanhar o produtor rural e capacitá-lo ao uso adequado desses produtos e promoção da sensibilização da população exposta a esses produtos que causam riscos ao ser humano e ao meio ambiente.

Published: February 2021

Este artigo de revisão vale-se de dados secundários para identificar as características e motivações de consumidores que se consideram “veganos” ou “vegetarianos” e para avaliar a importância e características dos mercados de produtos voltados para esses segmentos no Brasil e no mundo. Os mercados de alimentos “vegetarianos” e “veganos” representam um nicho de mercado – de forte crescimento no mundo – alavancado pela crescente preocupação dos consumidores com o impacto da alimentação em sua saúde, com o bem-estar animal e com o impacto ambiental dos sistemas produtivos, especialmente da produção pecuária. Esses motivos também têm atraído cada vez mais pessoas que, embora não se enquadrem nas categorias anteriores, compartilham essas preocupações e querem diminuir o consumo de alimentos de origem animal (os “flexitarianos”). Tal demanda tem levado a uma crescente oferta de produtos destinados a esses consumidores, com uma crescente diversidade de propostas que vão desde a oferta de alimentos in natura, processados ou, ainda, alimentos processados similares (substitutos) a produtos de origem animal. Essa oferta se distribui entre lojas especializadas, redes de supermercados, redes de restaurantes e vendas diretas pela internet em sites especializados. A dinâmica mercadológica desses produtos é observada tanto em países desenvolvidos como no Brasil.

Published: February 2021

Mental retardation is an intellectual disability characterized by intelligence being below average. People who are mentally retarded can learn new abilities, but the pace of learning is very slow. There are problems that often occur in the detection that children have mental retardation, especially by parents due to the lack of knowledge of the parents about this, resulting in the mistake of choosing the right type of learning for children. If this is allowed to continue, it will result in the child's mental condition getting worse. Due to these problems, a solution is offered in the form of an expert system application with the Case Based Reasoning (CBR) method, this method will match the symptom data of the old disease with the symptom data consulted by the user so that the similarity number of each type of mental retardation will be produced. The final result of this study is the percentage value of similarity along with recommendations in the form of suggestions and solutions that will be carried out by parents in providing independent education to children with mental retardation. The results obtained were in the form of mental retardation with a percentage of 0%, disabled with a percentage of 82.35%, with disabilities with a percentage of 0%.

Published: February 2021

Pendidikan dan pelatihan (diklat) merupakan salah satu proses untuk melatih kinerja para pegawai dalam melaksanakan tugas dan pekerjaannya agar lebih efektif dan efisien. Dalam penilaian untuk menentukan peserta diklat yang berprestasi, Kepala Bidang Kurikulum dan Teknologi mengambil nilai peserta dari hasil rata-rata pada setiap aspeknya. Pengambilan keputusan masih mengandalkan intuisi (subjektif), yang dapat menimbulkan hasil tidak objektif karena hasil rata-rata nilai yang masih terdapat kesamaan walaupun nilai pada setiap kriteria berbeda. Maka dari itu penulis membuat Sistem Pendukung Keputusan untuk menentukan peserta diklat berprestasi pada BPSDM Kemendagri  menggunakan metode TOPSIS, dengan 5 kriteria yang meliputi kedisiplinan (24%), kepemimpinan (12%), kerjasama (12%), prakarsa (12%) dan ujian akhir (40%). Dari 30 alternatif maka didapatkan peserta diklat berprestasi dengan nilai tertinggi 0,95 dan nilai terendah  0,05.

RIGHT LUNG WITH DISTINCT LOBAR PATTERN: AN UNUSUAL VARIANT
Authors: Chauhan Ankita , Yadav Suman , Patiyal Nitin
Published: February 2021

The lungs are paired, soft and spongy organs of respiration present in the greater part of thoracic cavity on either side of mediastinum resting on
diaphragm. The right lung is typically divided into three lobes namely superior, middle and inferior by the oblique and horizontal ssures. The left
lung is divided into superior and inferior lobes by a single deep oblique ssure. The ssures act as a plane of cleavage covered by extensions of
pulmonary pleura that helps in expansion of lungs during respiration. During the routine dissection of thoracic region of human cadaver, right lung
with accessory ssures and distinctive lobar pattern was observed. The right lung was divided into ve disproportionate lobes by four ssures. The
left lung had normal anatomy without any variation in this case. The variations in the ssures and lobar pattern of lungs are not uncommon and are
due to altered developmental process during intrauterine life. The anatomical knowledge of these variations is important for clinicians prior to
performing any pulmonary surgical procedures and to prevent postoperative complications.

Competitive Strategies for Wine Cooperatives in the German Wine Industry
Authors: Richter Barbara , Hanf Jon
Published: February 2021

The wine industry is significantly affected by globalization and changes in consumption habits and shifts in lifestyle, which lead to changes in the market environment and intensity of competition in the wine markets. Overall, wine cooperatives have a market share of more than 40 % in Europe. In Germany, they account for around one third of the total wine production. The decreasing number of wine cooperatives and their members leads to the assumption that wine cooperatives have difficulties adapting to the different market environment and though, need to select and implement competitive strategies. The aim of this paper is to identify and develop competitive strategies for wine cooperatives in the German wine industry. Therefore, the external forces affecting competitive rivalry in the wine industry are being evaluated for wine cooperatives in Germany. A qualitative approach has been applied including in-depth interviews with managing directors and chairmen of the board (n=15). Data were transcribed verbatim and content analysed. Results showed that the intensity of rivalry among existing competitors is high. Bargaining power of wine cooperatives towards buyers and suppliers strongly depends on their size. However, generally the bargaining power of retailers is high, although this depends on the retail channel (discounters, food retail, specialized retail, specialized wholesale, gastronomy). Five main strategy dimensions emerged: (1) the cost leadership and cost focus strategy, (2) the differentiation and differentiation focus strategy, (3) collaboration among producers, (4) offering additional services, and (5) options for improved membership relations and increased youth involvement.
