Unpacking ‘status migration’: The racialized status politics of ‘skill’ in French-Maghrebi expatriation to Dubai
Authors: Alloul Jaafar
Published: June 2021

This ethnographic article details the resettlement process of Mounir, a French citizen of Maghrebi background migrating from Paris to Dubai. In so doing, it examines how social status formation plays out in the context of skilled labour migration between France and the United Arab Emirates (UAE). Drawing on semi-structured interviews and multi-sited participant observation, it questions human capital theory’s premise that ‘skills’ largely consist of a transposable set of objective technical qualifications. Instead, it finds that any effective validation of skill sets encompasses ‘claims-making’ processes that are co-dependent on social hierarchies of place, such as citizenship, class and race. The ‘expatriate’ portrait presented here demonstrates how tertiary-educated members of the Euro-Maghrebi minority engage in transcontinental migration not only as a way of dealing with hampered economic conversion yields of Bourdieusian capital forms in their home societies, but equally to renegotiate a more comprehensive transformation of social status. By describing Mounir’s hybrid repositioning at the interstices of more dominant status markers in Dubai, this article theorizes ‘status migration’, a transnational process of human mobility, characterized by the skilful propensity of acting-by-moving from the part of (racially) degraded citizens in dealing with the status deficiencies specific to them in their home societies.

La contrarrevolución chilena. Raíces, dinámicas y legados de la movilización de masas contra la Unidad Popular
Authors: Casals Marcelo
Published: June 2021

La elección de Salvador Allende y la Unidad Popular en 1970 desató un radical y original proceso revolucionario, cuestión apreciable no sólo en la profundidad de las medidas redistributivas y las expectativas generadas, sino también en la ferocidad con que ese proyecto fue respondido por quienes se identificaron con un ideal contrarrevolucionario. Esa contrarrevolución inicialmente reducida a sectores conservadores y reaccionarios se transformó en cuestión de meses en una inmensa movilización de masas, que terminaría por pavimentar el camino hacia el golpe militar. Este ensayo analiza ese proceso contrarrevolucionario, explorando sus raíces históricas, los principales actores involucrados y la innovaciones en las prácticas políticas desarrolladas entonces. El “bloque contrarrevolucionario” formado por una diversidad de actores políticos y sociales -algunos de los cuales no tenían experiencia de movilización política previa- fundamentó su accionar en la adopción y socialización de un “guión” anticomunista de larga data, con el cual pudieron hacer sentido a la cambiante realidad de entonces. Ese “guión”, basado en décadas de recepciones de eventos de otras latitudes, elaboraciones y acusaciones contra todos aquellos identificados como comunistas, aspiró a reducir la originalidad del proyecto político de la Unidad Popular a una reedición en territorio chileno de las experiencias socialistas clásicas procesadas en clave distópica. La potencia de la contrarrevolución se proyectaría en la dictadura militariniciada en 1973 al convertirse en una suerte de ideología oficial de Estado, y se convertiría en una experiencia fundante de los sectores conservadores chilenos, con reverberaciones incluso en nuestros días.
A docência como profissão: O portfólio como dispositivo e política de formação docente no estágio supervisionado em educação física
Authors: Penteado Regina Zanella , Souza Neto Samuel
Published: June 2021

O objetivo deste trabalho é analisar se o portfólio, nas políticas de formação docente e no Estágio Supervisionado (ES) da Educação Física (EF), configura um dispositivo de formação e de profissionalização do ensino. Esta pesquisa qualitativa, documental, implementou uma análise de conteúdo das Diretrizes Curriculares de Formação de Professores e de 12 portfólios produzidos por estagiários em EF de uma universidade pública do Brasil. Os resultados integram narrativas dos portfólios dos estagiários, identificadas por eixos: avaliação diagnóstica e aprendizagem da docência. As políticas são interpretadas com atenção ao portfólio que é tratado sob a lógica de artefato técnico de atividade racional controlada (tencionando a noção de profissionalização). Concluímos que o uso dos portfólios  ampliou e se diferenciou daquele previsto pela literatura e atual política de formação docente. O portfólio no ES em EF emerge como possibilidade de dispositivo de formação aberto e flexível, que se coaduna com a profissionalização do ensino.

Vztahy mezi členy znovusložených rodin
Authors: Němcová Markéta
Published: June 2021

Today, so-called reunited families are an increasingly common type of family cohabitation. A considerable amount of research dealing with these families can be found in foreign literature. In the Czech environment, however, the issue of these families is neglected in research and very little is known about the specifics and dynamics of relationships between individual members of reunited families. Relationships within these families are quite intricately intertwined, especially from the point of view of a child who acquires a stepparent, a new sibling or other relatives. Exploring these relationships is not an easy task. Nevertheless, these families should not be neglected, as the disintegration of the original biological family is a stressful situation for all its members and affects the formation of a new family and, to a large extent, the development of children in these families. The following text presents an overview of the findings of mostly foreign research studies dealing with reconstituted families and the relationships between individual members of these families.

Authors: Aouf Mohamed K. , Lashin Abdel Moneim , Bulboacă Teodor
Published: June 2021

In this paper we introduce some new subclasses of thep-valent analytic functions with higher-order derivatives that generalize some related subclasses of starlike and convex functions of a positive order. We found the order of (p,q)-valent starlikeness and convexity for the products of functions that belong to these classes. The order of (p,q)-valent starlikeness and convexity of certain integral operators for the product of functions of these classes were also obtained.
On statistical convergence of sequences of closed sets in metric spaces
Authors: Georgiou Dimitrios , Megaritis Athanasios , Prinos Georgios , Sereti Fotini
Published: June 2021

In this paper, we do further investigations on the statistical inner and outer limits of sequences of closed sets in metric spaces, which were introduced by Nuray, Rhoades, and Talo, Sever, Başar, and generalize the conventional Painleve-Kuratowski inner and outer limits. Also, we provide criteria for checking statistical Wijsman and Hausdorff set convergences and we examine the relationship between Kuratowski and Wijsman statistical convergence. A closer look on the concept of statistical Cauchyness, with respect to the Hausdorff “extended” metric h, completes this research.

Motivation and psycho-emotional state in the competitive activities of veteran judokas
Authors: Alekseev A. , Ananchenko K. , Goloha V.
Published: June 2021

Purpose: to study the features of motivation and psycho-emotional state in the competitive activities of veteran judokas. Material and methods. The pedagogical research used analysis and generalization of scientific and methodological literature, surveys of athletes and specialists in judo, study of videos of competitive activities of highly qualified judokas and veteran judokas, methods of mathematical statistics. Results: the level of psycho-emotional sphere of athletes' personality was assessed by a modified test RB Ketella (16-FLO-105-C). The results of this testing showed that the main parameters of the psycho-emotional state in judo veterans are within normal limits. Veterans are characterized by more objective self-esteem, good intelligence, less subordination, and stable emotional stability. A questionnaire survey of veteran judokas was conducted, which revealed that 92,9 % of respondents started regular classes before the age of 15; 96,4 % interrupted active wrestling for 5-10 years; 28,6 % of veteran athletes sometimes included wrestling and its elements in their exercise. In order to determine the motives for sports activities of veteran judokas and young athletes, a modified version of the method of identifying significant factors of sports activities was used, which showed that veteran athletes and young judokas have different motivations for training. 71,4 % of judo veterans are motivated to return to sports by meeting the needs of competitive activities, getting closer to their «motor past» and maintaining good health; 21,4 % of the surveyed athletes returned for self-expression and self-affirmation, and only 7,1 % said they continued to exercise to meet their ambitions. The main motive for young athletes was the need for self-expression (46,9 %), material interest (33,9 %). Conclusions. Studies have shown little effect on the competitive outcome in veteran judo injuries and sports qualifications of athletes. Apparently, the basis of success of highly qualified judokas-veterans is high psychological readiness, strictly individual physical and technical and tactical training. Keywords: judo, psychological training, motivation, competitions, veterans, veterans' sports

Authors: Latyshev M. , Mozoliuk O. , Korolov B. , Liashenko O.
Published: June 2021

Purpose: to analyze the performances of the national Greco-Roman wrestling team of Ukraine at cadet and junior competitions from 1993 to the present. Material and methods. The research used the following methods: analysis of scientific and methodological information and Internet sources; analysis of the official protocols of the competition; retrospective analysis; methods of mathematical statistics. The performances of the athletes of the Greco-Roman wrestling national team of Ukraine at the European and world championships among cadets and juniors from 1993 to the present are analyzed. The number of participants, the number of medals earned, and the number of gold medals were counted. Results: based on the analysis of scientific and methodological information and generalization of advanced practical experience, it was found that the problem of analyzing competitive activity in modern sports is one of the most urgent. During the period under review, 209 athletes of the Ukrainian national team took part in the European Championships, of which 13 (6,2 %) became winners of the competition, and 55 (26,3 %) wrestlers took prizes. While 199 wrestlers have taken part in the European Championships among juniors since 1993, 71 (35,7 %) medals were won, of which 19 (9,5 %) were gold. In the period under review, 136 athletes took part in the world championships among cadets, and 12 (8,8 %) gold medals were won. Making comparisons, 192 athletes of the Ukrainian national team took part in the world championships among juniors, 10 (5,2 %) gold and 41 (21,4 %) medals in general were won. The analysis of the results showed that the largest number of athletes took the second, the third and the fifth places (more than 30 wrestlers for each place) at international competitions among cadets. The largest number of Greco-Roman style junior wrestlers of the Ukrainian national team took the following places: the third place (46 wrestlers), the fifth place (40 wrestlers) and the second place (37 wrestlers). Conclusions. The athletes of the Ukrainian national team show good results and occupy high places, however, there is a negative trend towards a decrease in the number of awards over time. Keywords: Greco-Roman wrestling, competitive activity, cadets, juniors, analysis.

Published: June 2021

Purpose: to reveal the peculiarities of teaching students of higher educational institutions of specializations of sports games and martial arts ski training. Material and methods. To solve the set tasks, we conducted a study in the 2020/2021 academic year with students of the Kharkiv State Academy of Physical Culture in the amount of 45 people, aged 18-20 years, for three weeks. Students were taught skiing techniques both according to the traditional system (control group) and according to the methodology developed by us (experimental groups). The time for learning the technique of skiing in both groups was the same 15 classes of classical style and 15 classes of skating style for 90 minutes each (according to the work program of the discipline), but the teaching methods in the experimental groups differed. The following methods were used during the research: theoretical analysis and generalization of scientific and methodological literature sources, working curricula and practical experience of teachers; analysis of information on the Internet; pedagogical observations; method of expert assessments; pedagogical experiment; methods of mathematical statistics. Results: as a result of the study, it was found that students of the experimental group (E1) received significantly better scores than the control group for performing the technique of movement in the classical style, the average score - 6.30, and the control group - 5.68 points (t=3,6; p<0,01), for performing the technique of skating style score (E1) was 6.18 points, and the control group – 5,25 points (t=5,2; p<0,01). Students of the experimental group (E2) for performing the technique of classical movement style received an average score of 5.93, compared with the control group - 5.68 points, no significant difference was found (p>0,05), the average score of the group (E2) for performing skating style was 5.90 points, and the control group – 5,25 points, which is significantly better (t=3,8; p<0,01). Conclusions. The use of different teaching methods, taking into account sports specializations, as well as the development of leading motor skills, has improved the learning outcomes of students of higher education specializations in sports games and martial arts ski training. As a result of the use of simulation and special training exercises without skis and on skis at the beginning of classes on the technique of classical and skating skiing, students of the group significantly improved the mastery of ski training on all indicators (p<0,01–0,05). Keywords: ski training, educational process, students, sports games, martial arts, motor abilities.

Este trabalho é parte de projeto coletivo de pesquisa mais ampla sobre novos modelos de formação de professores com alguns objetivos abrangendo comparações do Brasil e países da América Latina. No decorrer da pesquisa surgiu uma questão intrigante, qual seja, as semelhanças e as diferenças no que se refere a discursos e práticas de formação continuada de professores. Neste artigo, portanto, focalizam-se intervenções que compuseram agendas políticas nessa área. Os dados foram obtidos por meio de entrevistas e de documentos representados por leis, normativas e projetos de formação. Destacam-se, nessas intervenções, os discursos, mas também algumas práticas decorrentes. Foram tomados como base de análise os termos utilizados no Brasil e na Argentina, tais como: formação em serviço e fora do serviço; aperfeiçoamento; capacitação; formação contínua; e educação continuada. Esses termos e suas variações são analisados nas relações com as agendas políticas das últimas décadas com suporte da concepção de que a comparação permite a compreensão de como são propostas tais ações em cada país. As análises decorrem do uso da concepção relacional com políticas internacionais e com perspectiva da sociologia da cultura.
An analysis of direction of trade in select Indian agricultural commodities
Authors: Naipunya J. , Devi I. Bhavani , Rao D. Vishnusankar
Published: June 2021

An attempt is made in this paper to assess the dynamics of changes in exports of agricultural commodities namely, maize, chilli and Bengal gram, from India to different export markets by employing Markov chain model. The study is based on a set of countries importing agricultural commodities namely Nepal, others (pooled countries except selected countries) and Bangladesh were the most stable importers of the Indian maize with a probability of retention of 88.52 per cent, 68.90 percent and 61.09 per cent, respectively. The changing pattern of chilli exports through transitional probability matrices indicated that Thailand, other countries (pooled countries) and Vietnam were stable in importing Indian chilli with a probability of retention of 80.52 per cent, 69.02 per cent and 67.09 per cent, respectively. In case of Bengal gram, Pakistan was one of the stable countries as revealed by a probability of retention of its share i.e., 61.35 per cent. Algeria was also another stable importer as it retained its original share of 45.54 per cent followed by Turkey 41.13 per cent. The overall conclusion that emerges from present study is that Nepal, Thailand and Pakistan turned out to be the most stable countries in respect of importing Indian maize, chilli and Bengal gram.
A study on marketing of milk by small and marginal farmers in Khammam district of Telangana state
Authors: Sri Ch. Ramya , Suhasini K.
Published: June 2021

Dairying is recognized as an important source of income for small and marginal farmers in India, since on an average 22-26 per cent of the income of the rural households is contributed by milk. Low capital intensity, short operating cycle, steady returns make dairying a preferred livelihood activity among the small and marginal farmers. It helps to improve the status of rural masses especially weaker sections, consisting of small and marginal farmers, landless labourers and women of low income families. Cluster sampling technique is adopted for identification of three clusters which are mutually homogeneous but internally heterogeneous. The average size of family of selected marginal and small farms was 3.42 and 3.53 members, respectively. The average number of dairy animals possessed by small farmers are 1.32 units and marginal farmers are 1.47 units are small farmers and 1.47 units, respectively. Price realized for the dairy enterprise under taken is considered as key to success. In case of marginal farmers, maximum price of milk was obtained from channel through milk vendors (Rs. 44.66) followed by co-operative milk society (Rs. 42.66) and direct sale (Rs. 38). However, like marginal farmers small farmers also receive highest price from milk vendors (Rs. 46) followed by cooperatives (Rs. 42.66) and direct sale (Rs. 40). The price from milk venders is high by the farmers and the payment is prompt by them. Farmers in the study area were questioned about various government schemes and interventions for dairy farmers about which they are aware and they were beneficiaries. It was seen that none of the total respondents were taking any benefit from the government intervention. State government introduced a calf rearing programme “Sunandini” due to decreasing number of calves in the state and subsequent reduction in milk production. Telangana government has introduced a cash incentive of Rs. 4.00 per litre of milk to the state who supply milk to the state dairy federation in Telangana state.

Published: June 2021

Abstract Primary or secondary bone tumors can manifest in different ways, from simple bone pain to possible pathological fractures. Hypervascularized tumors are of greatest concern, with increased incidence of complications. Preoperative embolization of the bone tumor is an effective measure for reducing blood loss during open surgery to excise the tumor. With appropriate experience, the risks of the procedure are minimal and final outcomes are highly satisfactory. The purpose of this paper is to describe the case of a 43-year-old male patient with a metastatic renal cell tumor in the left proximal femur (seen on lower limb computed tomography) who underwent selective preoperative embolization. The procedure resulted in a remarkable absence of bleeding and successful response to subsequent onco-orthopedic surgery.

ABSTRACT The article proposes the existence of an actorial network that created a character-type of the male homosexual, which could be called the bicha louca (crazy fag). Actors such as Nestor Montemar, Raul Cortez, Ítalo Rossi and Emiliano Queiroz participated in this network, contributing to the theatre being a space of visibility for the LGBT population and of resistance to the moral and political repression in the period of the Brazilian civil-military dictatorship (1964-1985).
O circuito dos afetos na drogadição: uma explicação alternativa para a servidão às drogas
Authors: Kinoshita Roberto Tykanori
Published: June 2021

Apresentamos uma explicação alternativa para a noção de drogadição, refletindo sobre os motivos que levam uma pessoa a perseverar no consumo de drogas, mesmo sabendo dos malefícios decorrentes. Referenciado pelas obras de Humberto Maturana e pela teoria dos afetos na Ética de Spinoza, assumimos o pressuposto de que os seres humanos são movidos por paixões e formulamos o circuito dos afetos da drogadição. Identificamos nesse circuito três complexos afetivos: complexo singular pessoal, complexo de alívio/oblívio e complexo psicossocial, que formam uma dinâmica espiral de afetos tristes. Tais afetos compelem o indivíduo a continuar nessa dinâmica, e o papel das drogas passa a ser acessório. Cada complexo afetivo é caracterizado por afetos de origens distintas e a compreensão da particularidade e da especificidade de cada um organiza a ação de cuidado correspondente, a fim de interromper a dinâmica espiral do circuito.

Significance Statement

In autosomal dominant polycystic kidney disease (ADPKD), interstitial inflammation promotes cyst progression. TWEAK is a TNF superfamily cytokine that regulates inflammatory responses, and its receptor, Fn14, is expressed in nephron epithelium. This paper describes TWEAK’s role in ADPKD and its potential as a therapeutic target. The Fn14/TWEAK axis is upregulated in human and mouse polycystic kidneys, and TWEAK administration in mice accelerates cyst progression, whereas anti-TWEAK treatment slows cyst growth, improving kidney function and survival. Anti-TWEAK antibodies restore several ADPKD-related pathways, such as proliferation and NF-κB; slightly reduces fibrosis and apoptosis; and indirectly decreases macrophage recruitment. These findings identify the TWEAK signaling pathway as a new disease mechanism in ADPKD and a new possible therapeutic approach.

Background

In autosomal dominant polycystic kidney disease (ADPKD), cyst development and enlargement lead to ESKD. Macrophage recruitment and interstitial inflammation promote cyst growth. TWEAK is a TNF superfamily (TNFSF) cytokine that regulates inflammatory responses, cell proliferation, and cell death, and its receptor Fn14 (TNFRSF12a) is expressed in macrophage and nephron epithelia.

Methods

To evaluate the role of the TWEAK signaling pathway in cystic disease, we evaluated Fn14 expression in human and in an orthologous murine model of ADPKD. We also explored the cystic response to TWEAK signaling pathway activation and inhibition by peritoneal injection.

Results

Meta-analysis of published animal-model data of cystic disease reveals mRNA upregulation of several components of the TWEAK signaling pathway. We also observed that TWEAK and Fn14 were overexpressed in mouse ADPKD kidney cysts, and TWEAK was significantly high in urine and cystic fluid from patients with ADPKD. TWEAK administration induced cystogenesis and increased cystic growth, worsening the phenotype in a murine ADPKD model. Anti-TWEAK antibodies significantly slowed the progression of ADPKD, preserved renal function, and improved survival. Furthermore, the anti-TWEAK cystogenesis reduction is related to decreased cell proliferation–related MAPK signaling, decreased NF-κB pathway activation, a slight reduction of fibrosis and apoptosis, and an indirect decrease in macrophage recruitment.

Conclusions

This study identifies the TWEAK signaling pathway as a new disease mechanism involved in cystogenesis and cystic growth and may lead to a new therapeutic approach in ADPKD.

A Duty Perspective on the Hate Speech Prohibition in the Equality Act
Authors: Marais Marelize
Published: June 2021

In this contribution, I argue that every person's duty to respect others is central to section 10(1) of the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 ("the Equality Act"), otherwise known as the "hate speech" prohibition. This duty should therefore also be a central consideration in its interpretation. Related duties are those of the state to enact legislation, and of courts to interpret and apply the law to promote the spirit, purport and objects of the Bill of Rights. Our courts have in many instances considered the duty to respect others, as well as the state's and the courts' related duties, in the interpretation of socioeconomic rights and the development of the common law. In doing so, they have consistently employed the reasonableness standard. Therefore, references to relevant case law in various legal contexts provide the framework within which I examine legal duties in the context of unfair discrimination and, in particular, hate speech in terms of section 10(1) of the Equality Act. I examine the constitutional obligations of the state, the courts and private persons to promote respect for the dignity of others. I reiterate the state's specific obligation in terms of section 9(4) of the Constitution of the Republic of South Africa, 1996, to enact legislation to prevent or prohibit unfair discrimination on the grounds listed in section 9(3). Finally, I relate these duties to the section 10(1) prohibition in the Equality Act. I apply the reasonableness standard to conclude that the prohibition gives due effect to the duties of the state and every person, and that the courts are duty-bound to interpret it accordingly. This conclusion refutes the Supreme Court of Appeal's ruling in Qwelane v South African Human Rights Commission ("Qwelane")[1] that the section 10(1) prohibition was vague, overbroad and, therefore, unjustifiably infringing the right to freedom of expression.

Şiirsel Bir Savaş: Anzak Günlüklerindeki Şiirlerde Gelibolu Muharebeleri
Authors: ÇELİKEL Mehmet Ali
Published: June 2021

Birinci Dünya Savaşında, Çanakkale Boğazı’nda Türk ve Britanya orduları arasında sekiz ay süren çarpışmalar boyunca, Anzak birlikleri olarak bilinen, Avustralya ve Yeni Zelanda birlikleri Gelibolu’da karargâh kurmuşlardır. Anzak askerler tarihe kişisel olarak tanıklık ederek günlükler tutmuşlar ve mektuplar yazmışlardır. 1915’teki Gelibolu muharebeleri sırasında tutulan Anzak günlükleri yalnızca ikincil tarihsel kaynaklar değildir. Aynı zamanda kendilerini şiirle ifade ederek rahatlatmak isteyen askerler anılarını da kayda geçirmektedir. Kimi Anzak askerleri günlüklerinde şiirler de yazmışlar ve savaşın zorlukları ve acılarına şiirin lirizmiyle katlanmaya çalışmışlardır. Bu şiirler yalnızca tarihsel gerçeklerin yansımaları değil, savaşın acı betimlemeleri olarak da karşımıza çıkmaktadırlar.

Bu makale Anzak askerlerin günlüklerindeki şiirlerde savaşın bireyler üzerindeki etkilerini incelemektedir. Günlüklerdeki şiirler tarihsel kaynaklar olarak değil, tarihi şiirin bir malzemesi olarak kullanan metinler olarak okunmaktadır. Çalışmada tarihsel olayların şiir yazımının ardındaki ana etken olmadığı, tersine şiirin temel kaynaklarından biri olduğu da vurgulanmaktadır.

Warna merah merupakan salah satu faktor penentu kualitas ikan tuna loin. Setelah dipotong dan disimpan  ikan tuna akan mengalami perubahan warna, sehingga untuk mempertahankan warna merah pada daging ikan tuna digunakan filtered smoke. Filtered smoke juga dapat mengurangi oksidasi lemak dan mempertahankan kualitas asam lemak. Penelitian ini bertujuan untuk mempelajari komposisi asam lemak tuna loin (Thunnus albacares) yang diperlakukan dengan penyemprotan filtered smoke selama penyimpanan. Penelitian menggunakan metode eksperimen, ikan tuna loin disemprot dengan gas filtered smoke kemudian disimpan beku (-25 ºC) selama empat minggu. Pengamatan berlangsung  pada minggu ke-0 dan minggu ke-4 . Variabel mutu yang diuji adalah profil asam lemak, indeks atherogenic (AI), indeks thrombogenic (TI), kualitas lemak (h/H) dan  indeks poliena. Hasil analisis diperoleh asam lemak sebanyak 29  jenis terdiri dari asam lemak jenuh (SFA) 13, asam lemak tak jenuh tunggal (MUFA) 6 dan asam lemak tak jenuh jamak (PUFA) 13. SAFA tertinggi adalah asam palmitat (C16:0), sebesar 8,93% dan 15,14%, MUFA tertinggi adalah asam oleat (C18:1n9c) sebesar 3,73% dan 5,01% dan PUFA tertinggi adalah asam dokosaheksaenoat (C22:6n3) sebesar  6,77% dan 5,73%, masing-masing untuk minggu ke 0 dan minggu ke 4. Kualitas lemak ikan tuna masih tergolong baik setelah disimpan selama empat minggu, dengan nilai AI  0,83, nilai TI 0,69, nilai h/H 1,72 dan nilai indeks polien 1,31.

Dalam sebuah masyarakat terutama masyarakat Indonesia, kita dihadapkan dengan konsekuensi adanya beberapa konflik yang melibatkan perselisihan ras, suku, bahkan agama. Seperti sebuah desa di Jember, Kecamatan Umbulsari, yang bernama desa Sukoreno. Untuk menghindari hal tersebut toleransi diagung-agungkan untuk disosialisasikan dan diinternalisasikan di setiap anggota masyarakat baik dari tingkat sekolah sampai pada aktivitas lainnya di Desa. Adanya sebuah perayaan besar dimanfaatkan oleh berbagai pihak sebagai ajang mempererat tali persaudaraan antar warga desa. Setiap adanya event, selalu ada tangan-tangan lain yang ikut membantu dikarenakan nilai luhur yang mengakar akan sebuah rasa gotong royong khas masyarakat desa, apapun agamnya, hal ini juga yang ingin dipertahankan oleh beberapa pihak untuk memelihara desa dengan pendapukkan desa Pancasila. Tulisan ini dibuat untuk mengetahui penyebab sebuah kebudayaan bisa diselenggarakan dalam keberagaman umat dan menjadikannya faktor pendorong toleransi. Penelitian ini dilakukan dengan cara wawancara dan merangkum beberapa informasi dari informan yang layak dijadiakn bahasan sesuai tema, secara purposive.  Karena dengan adanya pendidikan pembiasaan local wisdom akan tetap terjaga. Bangsa Indonesia berkomiten bahwasannya negara multikultur dan multi agama ini perlu adanya komitmen yang kuat akan toleransi dan integrasi dalam pengemasannya. Kebiasaan, apresiasi, dan partisipasi masyaraat inilah yang nantinya akan membentuk kerukunan sesuai kebiasaan uri-uri budaya yang dilakukanya guna mempersatukan perbedaan akan kesadaran kognitif yang terintegrasi.

The aim of this paper is the control of electric powered wheelchairs (EPW) which was made for people suffering of temporary or permanent disabilities due to illnesses or accidents. The EPW is powered by two Permanent Magnet Synchronous Motors (PMSM) that are characterized by high efficiency, high torque, low noise and robustness; hence the dynamic model of the both EPW-motors is presented in the first. After that, a comparative study is made between two nonlinear command theory; Integrator Backstepping based on the second method of Lyapunov which combine the choice of the energy function with the laws control, and, fuzzy logic introduced to approach human reasoning with the help of an adequate representation of knowledge. To evaluate the performance of the two controls, numerical simulations are presented to show the evolution of electrical and mechanical quantities, the energy consumed and the squared error of the displacement and velocity. However, the reference trajectory used is that generated by the fifth-degree polynomial interpolation, which ensures a regular trajectory that is continuous in positions, velocities and accelerations.

Published: June 2021

The bidirectional dc-dc converter with high voltage gain and high efficiency plays an important role in the designing of battery charging systems. In this paper, design and development of a battery charging system utilizing coupled inductor based high gain dc-dc converter is presented. The converter uses a clamp capacitor network to recover the leakage energy of a coupled inductor. The converter has inherent soft-switching capability during turn ON, which ensures high efficiency at high switching frequency. Design equations to derive value of different passive components are given and a step-wise exclusive design to construct coupled inductor is presented. A 50 kHz, 500 W laboratory prototype has been designed, which can increase the voltage with 10 gain (boost operation) in one direction and can reduce the voltage at (1/10) gain (buck operation) in other direction. The CCCV battery charging algorithm is implemented using generic ARM Cortex-M4 microcontroller. Extensive experiments have been performed and the experimental results are presented in buck, boost, and battery charging operations.
