GE SiC Semiconductor Device Operation at Extreme Temperatures
Authors: Esler David
Published: June 2021

GE Research has been working on the design, packaging, and testing of SiC Power semiconductors devices at junction temperatures up to 500°C for the past 5 years. Intrinsically, SiC power devices are able to endure and operate reliably at harsh environments. Limiting factors to packaged devices’ operation at high temperature are the contact metallization and packaging. While testing bare die power devices, probe contact resistance was found to be an issue for resistance measurements at very high temperatures. On the backside contact, traditional die attach solders have operational temperature limits. Using insulated metal substrates, sintered die attach, and wedge bond interconnect, GE Research tested its power devices up to 500°C junction temperature. GE Research also demonstrated various junction termination dielectric stackups which can block up to 1000V at 500°C junction and show improvements over traditional organic dielectric options (e.g. Epoxy, Silicone, Polyimide).
Package Design and Analysis for Vertical Gallium Nitride Field Effect Transistors
Authors: Harris John , Huitink David , Ewing Dan
Published: June 2021

Gallium nitride (GaN) is a wide band gap semi-conductor with superior electron mobility to silicon carbide. These properties allow for the design of high temperature capable devices with excellent on resistance and breakdown voltage for their size. However, bulk GaN is difficult to fabricate and doping for field effect transistor (FET) control has been elusive, so vertical GaN devices are not commonplace. This paper measures the characteristics of vertical GaN FETs in the development stage and discusses packaging them for fabrication feedback and for future high temperature aplications.
A 300°C High Reliability HALT/HAST Screening/Sorting Procedure for Ceramic Capacitors – Part 2
Authors: Snyder Harold L.
Published: June 2021

This is Part 2 of a study initially presented at HiTEC 2018, for context, some introductory material is duplicated. A highly accelerated life test (HALT) and highly accelerated stress test (HAST) procedure for ceramic capacitors developed by the author in the mid 1980’s to early 1990’s, and published in 1994, consists of a 400 Volt biased six (6) hour stress sort at 150°C (423K), a methanol current leakage test that located mechanical and structural cracks, a visual inspection at ten times (10X) magnification, and a capacitance and dissipation measurement before and after the test. In over thirty (30) years of use, there has never been a user reported in-circuit failure in industrial, military, and aerospace application at temperatures as high as 500°C (773K). However, reviewing user feedback, two concerns with the original sorting procedure are the stress is performed at 150°C (423K), and the lack of a more detailed ceramic capacitor electrical model. To address the first, the low aging temperature, the stress temperature was increased from 150°C to 300°C, in order to age ceramic solid state crystal mineral phases that may change with temperature. The test results for X7R and NP0/COG multilayer ceramic capacitors (MLCC) at 300°C, are compared to the test results using the original HALT/HAST procedure at 150°C. Differences between X7R/NP0/COG and porcelain capacitors are discussed when applicable. Further, a more detailed ceramic capacitor electrical model that represents the physical and electrical characteristics of the ceramic capacitors is presented, including the electrical current leakage effects with temperature, and the carbonized residue effects from the manufacturing process.

Experimental Validation of Voltage Regulation in Buck Converters through Fractional-Order PID Approximation
Authors: Soto-Vega Josué , S. Sánchez Allan G.
Published: June 2021

Viability of a fractional-order PID approximation regulating voltage in buck converters through a single control loop is investigated. Fractional calculus approach is suggested due to it exhibits good robustness against parameter variations. The non-integer approach is integrated in the control strategy through a Laplacian operator biquadratic approximation to generate a flat phase curve in the system closed-loop frequency response, which results in the generation of the iso-damping characteristic. The synthesis and tuning process consider both robustness and closed-loop requirements to ensure a fast and stable regulation characteristic. Experimental data obtained with the resulting controller, which was easy implemented through RC circuits and OPAMPs in adder configuration, confirmed its effectiveness. Superiority of proposed approach, which is determined through a comparison with typical PID controllers, confirms its viability to be used in highly efficient converters, such as Silicon-Carbide ones.
Contexto histórico, político e ideológico en el que emerge la corriente de pensamiento liberal socialista
Authors: Martínez Palmezano Jairo
Published: June 2021

El objetivo de esta investigación fue describir el contexto histórico, político e ideológico en el que emerge la corriente de pensamiento liberal socialista, formulada, por Norberto Bobbio, entre otros. En este sentido, se expone el contexto histórico en el que surge la Unión de Repúblicas Socialistas Soviéticas al calor de la llamada revolución de octubre de 1917, como condición de posibilidad para entender críticamente el influjo de la promesa socialista en la mente de los intelectuales críticos de la época, ganados a construir una sociedad más justa y equitativa para las masas obreras. En lo metodológico se hizo uso de la observación documental y del enfoque ideacional. La interpretación de las fuentes recabadas permite concluir que, en la lectura de los procesos ideológicos, prevalecen las posturas pasionales por sobre la razón, de ahí que para los intelectuales comunistas la URSS significaba un mundo mejor, al menos para los trabajadores y las clases desposeídas y, para los liberales, la democracia liberal y sus economías de mercado son la única alternativa posible para impulsar el progreso de las naciones. De cualquier modo, el aporte de la obra de Bobbio se debe a su capacidad intrínseca para superar la polarización ideológica.

In the first part of the paper are analyzed different views of the rule of law: liberaldemocratic, then positivistic view and, finally, defining of the rule of law as the rule of positive-law order of particular properities. In addition to these the three theoretic orientations, one more classification was pointed out - formal and materaialistic aspect of the rule of law. Besides, the principles and institutions of the rule of law were analyzed: legitimacy of power, division of power, independent judiciary, legitimacy expressed in terms of the ideas of constitution and lawfulness, constitutional guarantees of human and civil rights, existence of free economy and economic activities. The subject of the second part of this paper are services. Nowadays, services are the motor of economic growth and include, especially in developed countries of EU, more then 70% of EDP, employees, new economic subjects, and service activities also make up over 70% of all the activities. The service sector includes different, heterogenic services the number of which is getting higher and higher. The service activities are numerous and performed in various sectors such as trading, communications, financing, government administration, health department, social welfare, media, education, tourism, catering, sport and others. We are all witness to the constant growth of service sector in view of continuous broadening of the range of services and the influence upon the economic development of the state. Law regulations of the services in the Republic of Serbia were analized as well as its harmonization with the law regulations at the level of EU and the need for its further upgrading and improvement.

We, as the authors of this text, have found it important to point out the close connection between law and justice, theory and practice, because citizens go to court for justice. The judge says what justice is. However, when the legal norm is available and well known to the persons, to whom it refers, and when it is predictable and the case law is uniform, the persons to whom the legal norm refers, can know their rights and obligations concretely, and thus know how to treat them. In order to that they must behave and anticipate the consequences of their behavior. When all the above has been fulfilled, it can be said that the requirements of the rule of law and legal security have been met, so it can be freely said that law and justice are at the "service of the people", through theory and practice. It should be reminded that the precision of the legal norm is one of the basic elements of the rule of law and is a key factor for the emergence and maintenance of the legitimacy of the legal order, which applies to all branches of law, and that court decisions are binding on all.

Published: June 2021

Introdução: Complicações cardiovasculares associadas à infecção por coronavírus foram descritas a partir de infecções por SARS-CoV e, recentemente, SARS-CoV-2, que gera o padrão clínico da doença denominada COVID-19. O SARS-CoV-2 causa lesões miocárdicas agudas, miocardite e insuficiência cardíaca. A susceptibilidade endotelial e miocárdica em pessoas com Covid-19 foi relacionada a processos inflamatórios e trombolíticos com implicações sistêmicas, que demandam intervenções complexas e operação multiprofissional. Objetivo: Demonstrar, por meio de uma revisão de pesquisas recentes, os mecanismos pelos quais o vírus SARS-CoV-2 produz dano miocárdico com alta mortalidade em pacientes acometidos por COVID-19. Métodos: Trata-se de uma revisão bibliográfica, realizada entre os anos de 2019 e 2021. As bases eletrônicas de dados utilizadas foram: Scielo, Lilacs e Pubmed. Foram utilizados os descritores: miocardiopatia, Covid-19, Sars-cov-2 segundo a biblioteca virtual em Saúde (BVS). Resultados: Observou-se que a injúria do miocárdio, definida pela elevação dos níveis de troponina acima do valor de referência, é uma complicação frequente (19,7%) nos pacientes internados por COVID-19 e está associada ao aumento de mortalidade e síndrome do desconforto respiratório agudo. Houve uma forte correlação entre níveis altos de troponina e aumento de proteína C reativa e de NT-proBNP. Pacientes com níveis aumentados de troponina tiveram maior incidência de arritmias ventriculares e maior necessidade de ventilação mecânica. Conclusão: Pacientes com comorbidades como diabetes, hipertensão e doenças cardiovasculares têm maior suscetibilidade à forma grave da Covid-19 e complicações cardiovasculares como a miocardiopatia. Portanto, torna-se necessário o acompanhamento cardiovascular destes pacientes, posto que, à luz dos conhecimentos atuais, não sabemos se eles poderão ou não evoluir com disfunção miocárdica tardia.

Published: June 2021

The agronomic and chemical characteristics of aromatic plants are affected by nutritional sources. Salvia officinalis (common sage) is an aromatic plant extensively used in food, popular medicine, and many pharmacological research studies. In this study, the effects of NPK, vermicompost and two types of microbiological fertilizer were investigated on the agronomic parameters and volatile oil characteristics of S. officinalis grown in the greenhouse. The plants were harvested two times (1st and 2nd cuttings) during the growing season. The consumption of NPK has the highest effect on stem number (54 no plant-1), fresh and dry herb weight (96.8 and 27.2 g p-1), fresh and dry leaf weight (74.6 and 19.6 g p-1), and volatile oil percentage (1.64%). While the herb weight at the 1st cutting (74.3 g p-1) was higher than the 2nd cutting (70.2 g p-1), the fresh (58.2 g p-1) and dry (16.6 g p-1) leaf weights and the leaf ratio (80.5 %) at the 2nd cutting were higher than the 1st cutting. Moreover, the volatile oil contents at the 1st cutting (1.44%) were higher than the 2nd cutting (1.18%). In total, 31 compounds were identified in the volatile oils by using GC/FID-MS. The percentages of α-Thujone (22.4-31.4%) and Camphor (21.0-25.4%) were found higher than other compounds. The content of α-Thujone was higher in NPK and vermicompost treatments. Based on the results, the application of different nutritional sources improved the yield and chemical properties of S. officinalis. Among the non-chemical nutrient sources, vermicompost had high efficiency.

Investigation of Doppler Collision Effects in Kinematic Conditions and its Mitigation for NavIC System
Authors: Sathish P. , Manga N. Alivelu
Published: June 2021

NavIC (Navigation with Indian Constellation) constellation consists of four geosynchronous and three geostationary satellites and it is developed by ISRO, India. It provides position, velocity and timing services. Doppler Collision (DC) is a phenomenon where tracking errors are introduced in the measurements due to cross-correlation between the satellites. If relative doppler between satellites is less than the code loop bandwidth, then DC occurs. In this paper, to analyze DC impact on NavIC, the Doppler shift of each GEO satellite is calculated, the most effected GEO satellite pair is identified. In high dynamic applications like missile launches the effect of DC is very significant. In order to investigate DC in high dynamic conditions a simulation of trajectory path of the receiver is considered. For the precise position estimation, the contribution of DC error will be high, so it needs to be minimized. An efficient algorithm is developed to mitigate the DC using narrow correlator design of the receiver. Using the proposed algorithm, the DC duration for 1C-1G satellite pair has been reduced from 50min 21sec to 2sec in static conditions. Whereas in dynamic conditions from 4h20min 28sec to 5sec with DLL bandwidth of 4Hz and 0.1 chip spacing of receiver design.

The Malaysian government strongly encourage the application of new techniques in building construction such as the Industrialized Building System (IBS). With this new IBS technology, numerous advantages will be obtained and will directly raise the performance of the building. However, the acceptance of IBS in Malaysia is still low. There are many components of IBS. The objective of this paper is to describe the Interlocking Mortarless Blocks System (IMB) and to identify the challenges in the utilization of the mortarless blocks system in housing construction. This research was carried out in Ipoh, Perak, with a focus on housing construction projects. Questionnaire was provided for the respondents to answer. The data was analyzed using the descriptive analysis from the SPSS software. The result revealed that one of the challenges is contractors who tend to use traditional construction method rather than the Interlocking Mortarless Blocks system method. The usage of Interlocking Mortarless Blocks in Malaysian is still low as there is no specific standard on Interlocking Mortarless Blocks system. Therefore, the findings of this research can hopefully assist Malaysian contractors in making a decision on the component to be used in their projects. Additionally, the findings ensure that the government can take appropriate action to encourage the use of IBS, especially the Interlocking Mortarless Blocks

Abstract

Agriculture is considered one of the most important economic sectors in the European Union as it accounts for a large percentage (about 44%) of the EU budget, but also due to the fact that a large part of its population and areas are affected by agricultural activities. In Greece, the agricultural sector is the main district of the economy with an irreplaceable and crucial role as an important employer for a large workforce, thus ensuring social cohesion and regional development. Following Greece's accession to the EU, Greek agriculture is defined by the rules of European agriculture through the Common Agricultural Policy (CAP). In general, the role of agriculture in Greece is proved by the fact that it occupies a large percentage of its land (about 30%) and employs 82% of rural population compared to 43% of urban population. Rural population in Greece is higher than that of the rest EU member states. The agricultural sector contributes to the country's GDP directly about 4% of the gross value added of the Greek economy and despite the problems it faces, it has demonstrated relative resilience to adverse economic conditions of recent years. In the present work, statistics concerning the agricultural employment in Greece are given and the main structural problems of Greek Agriculture are mentioned. In terms of agricultural employment, the absolute number of people has decreased significantly over time. The ratio employees in agricultural sector to the total number of employees decreased from 24% in 1989 to 15.2% in 2000 and 10.6% in 2017 but still remains significantly higher than the average of 4.4 % in 2017 in the European Union. Thus, in 2017 in Greece, 453,440 thousand people worked in agriculture. In connection with the outbreak of the Coronavirus Pandemic, especially in Greece, it was found that there is a lack of labor in the countryside and that the orientation of the economy should be directed to the agricultural sector to avoid possible food shortages and most importantly that this sector may lead to the stabilization of the Greek economy.

La definición de población indígena ha estado sujeta a diversos criterios e infinidad de debates; esta misma presenta un espectro de variación y contraste tan amplio que ninguna definición, a partir de sus características internas, puede in co r p o r ar a to d as . En tan to , la socialización de los individuos desde el atisbo de la gentrificación de la población y cultura indígena sugiere que en el traspaso cultural de saberes se permite establecer y transmitir valores, normas y costumbres, actividad predominantemente ejercida por mujeres; sobre todo desde la concepción del arte popular textil, que es quizá uno de los pilares más imp o r tan tes en la conformación identitaria nacional.

Covid 19 salgını nedeniyle Türkiye’de ve birçok ülkede, okulları ya kıs-men ya da tamamen kapatmıştır. Türkiye’de de okullara öncelikle ara veril-miş, sonrasında belirli tarihlere kadar açılması ertelenmiş ve 2019-2020 ikinci yarısı ile 2020-2021 birinci ve ikinci yarısında öğrenciler yüz yüze eğitimden çoğunlukla mahrum kalmışlardır. Bu araştırma DKAB öğretmenlerinin salgın boyunca uzaktan öğretimdeki öğrenme-öğretme sürecinde yaşadığı sorunları betimlemeyi amaçlamaktadır. Araştırma, nitel araştırma yöntemlerinden durum çalışmasına göre tasarlanmıştır. Çalışma grubunu dört erkek, dört kadın olmak üzere toplam 8 DKAB öğretmeni oluşturmaktadır. Veri toplama aracı yarı yapılandırılmış görüşme formudur. Veriler içerik analizine tabi tutulmuş, NVİVO 12 programından istifade edilmiştir. Çalışmada DKAB öğretmenlerinin; tekniğe, devamsızlığa, ders öncesi hazırlığa, öğrenme ortamına, öğretim yöntemlerine, motivasyona, iletişime, zamana ve ölçme-değerlendirmeye dair sorunlar yaşadıkları tespit edilmiştir. Bu sorunlara rağmen öğretmenlerin normalleşmeyle birlikte uzaktan eğitimdeki kazanımları kullanmaya istekli oldukları, öğrenmeyi bu şekilde sınıf dışına çıkarmayı hedefledikleri de söylenebilir. Araştırmacılara sınıf mahremiyeti, dijital dünya ahlakı kavramlarının eğitim çerçevesinden çalışılması önerilebilir. DKAB öğretmenlerinin teknoloji kullanım yeterliliklerinin geliştirilmesi de ilgili kurumlara önerilebilir.

Politikai átrendeződés a Perzsa-öbölben? : A kuvaiti és ománi uralkodóváltás tanulságai
Authors: Szalai Máté , Vara Bálint
Published: June 2021

Az elemzés célja két Perzsa-öböl menti kisállam, Kuvait és Omán 2020-ban lezajlott örökösödési folyamatának, valamint azok következményeinek értékelése. Ugyan a két ország politikai rendszere számos eltérő jellegzetességgel bír, hasonlóságokat láthatunk a rezsimek szerepében, valamint a tavaly végbement uralkodóváltások politikai kontextusában, elsősorban a generációk közötti vetélkedés kiéleződése, valamint a megváltozott információs környezet átalakulása tekintetében. Ugyan egyik esetben sem vonhatunk le még végleges következtetéseket, egyelőre mégis úgy tűnik, hogy az öröklés után elindult folyamatok Omán esetében nagyobb stabilitáshoz vezetnek.

Authors: Steven Witman
Published: June 2021

Tingkat efisiensi dari penggunaan air yang ada dilahan pertanian bahwasanya dapat dioptimalkan dengan cara melakukan penggunaan metode teknik irigasi yang tepat dikarenakan teknologi irigasi merupakan salah satu komponen yang dirasa penting karena tingkat produksi dari hasil pertanian ditentukan berdasarkan kondisi tanah, perawatan terhadap tanaman, kecukupan air pada tanaman serta iklim yang ada. Dalam bidang pertanian faktor iklim adalah sesuatu hal yang tidak dapat dihindari terutama kondisi iklim saat musim kemarau, tentu bisa menjadi suatu kendala terhadap pertumbuhan tanaman, dikarenakan pasokan air terhadap tanaman kurang terpenuhi, dengan penerapan metode Irigasi tetes bisa menjadi salah satu solusi dalam menangani permasalahan kebutuhan air pada tanaman. Metode penerapan irigasi tetes ini yakni pemberian air dalam volume kecil dan berkelanjutan, irigasi tetes ini juga bertujuan untuk menjaga kelembaban tanah dan kehilangan air yang disebabkan musim kemarau sehingga ketersediaan air bagi tanaman terpenuhi. Teknik irigasi tetes inilah yang diharapkan dapat membantu dalam pemenuhan kebutuhan air dan tanaman sehingga dapat meningkatnya pemanfaaatan unsur hara pada tanah, mempercepat bibit tanaman untuk beradaptasi, dan juga nantinya akan meningkatnya keberhasilan tanaman tersebut untuk bisa tumbuh. Untuk memaksimalkan tingkat efisiensi dalam penggunaan air bisa menggunakan tanah yang memiliki tekstur liat dikarenakan tekstur tanah seperti ini memiliki tingkat penyimpanan air yang sangat tinggi. Selain itu pengaplikasian sistem irigasi ini bisa dilakukan pada tanaman buah ataupun sayuran.

Padi ladang merupakan komoditas potensial untuk dikembangkan karena luas lahan kering yang tinggi di Kabupaten Manokwari. BPTP Papua Barat melaksanakan pengembangan padi ladang amfibi sejak 2018 karena varietas padi ini memiliki kemampuan bertahan pada kondisi genangan air maupun dalam kondisi lahan yang kering. Padi amfibi merupakan padi baru di Kabupaten Manokwari dengan berbagai kelebihan yang menguntungkan apabila dibandingkan dengan padi yang sudah ditanam turun-temurun oleh petani. Penerapan panca usahatani padi ladang amfibi terdiri dari lima komponen yaitu: a). penggunaan benih unggul, b). pengolahan lahan, c). irigasi atau ketercukupan air, d). pemupukan berimbang dan e). pengendalian hama penyakit. Hasil evaluasi menunjukkan bahwa petani sudah mengikuti rekomendasi dalam menggunakan benih unggul dan mempertimbangkan kecukupan air sebesar 100% atau diterapkan sepenuhnya. Komponen pengolahan lahan diterapkan 50%, pemupukan berimbang diterapkan 62% dan pengendalian hama penyakit diterapkan 62%. Kegiatan yang dilaksanakan oleh BPTP ini didukung oleh petani lokal dan petani transmigran yang menanam padi ladang. Produksi dan produktivitas yang dihasilkan petani diharapkan dapat meningkat dengan menerapkan panca usahatani padi ladang amfibi yang direkomendasikan. Penelitian ini dilaksanakan bertujuan untuk menganalisis faktor-faktor yang mempengaruhi penerapan panca usahatani padi ladang amfibi. Hasil penelitian menunjukkan bahwa penerapan panca usahatani termasuk dalam kategori sedang karena dipengaruhi oleh faktor pendidikan, modal usahatani, frekuensi penyuluhan, ketersediaan lembaga keuangan dan sosial budaya.

Published: June 2021

O presente trabalho teve por objetivo avaliar as condições ambientais do Rio Preguiças em Barreirinhas, Maranhão, Brasil, através de análises ambientais feitas a partir da aplicação do instrumento conhecido como Protocolo de Avaliação Rápida.  A ferramenta intitulada “Protocolo de Avaliação Rápida” consistiu-se com um instrumento avaliador das condições ambientais de corpos hídricos, tendo por características variáveis e pontuações (0, 1, 2 e 4 pontos) para cada aspecto avaliado.  Esta pesquisa teve por objeto de estudo três pontos principais do rio problematizado: Porto da Avenida Beira Rio (Ponto - 1), o Porto do Amapá (Ponto - 2) e Porto do São Domingos (Ponto - 3), onde, de acordo com as pontuações alcançadas ao final da aplicação do formulário de avaliação, pode-se fazer as classificações dos trechos estudos como: Trecho impactado: 0 a 11 pontos; Trecho alterado: 12 a 22 pontos e Trecho natural: 23 a 44 pontos. No que se refere aos resultados levantados, o ponto 1 pode ser classificado como “Trecho com alteração ambiental”, por apresentar pontuações negativas em grande parte dos aspectos estudados. As outras áreas avaliadas receberam o status de Trecho Natural, apesar de possuírem alguns aspectos negativos em certos momentos. O ponto 1 apresentou caraterísticas, que apesarem de já impulsionarem certas preocupações, ainda é possível reverter. No que se diz respeita as demais localidades estudas, elas não manifestaram grandes aspectos que levam a imediata degradação ao corpo hídrico aqui enfatizado, porém, caso as variantes se agravarem, pode ser que haja comprometimento maior do meio ambiente aquático apontado.
