Authors: Junlakan Wannapit , Yamsaengsung Ram , Tirawanichakul Supawan
Published: October 2019

The objective of this research was to study the optimum condition for the vacuum drying of banana slices using a vacuum dryer and to find out the appropriate thin layer equation for predicting the drying kinetic of bananas. The experiments were carried out at the drying temperatures of 60, 70, 80 and 90oC and absolute chamber pressure of 30 mmHg. The drying experiments were performed until the samples moisture content was lower than 3.4% (w.b.). Next, the dried products were analyzed for physical quality (in terms of color, shrinkage, and texture) and sensory quality (in terms of color, texture, flavor, crispness and overall acceptability). These data were used in choosing the optimum condition for the vacuum drying of banana slices. From experimental results, the drying time at the highest drying temperature was the shortest. At this condition, the dried banana slices showed the highest degree of yellowness, lower shrinkage, and more crispness compared to lower drying temperatures. From sensory analysis, each drying condition showed significant effect on consumer acceptability with the drying temperature of 70, 80 and 90oC showing the levels of the overall acceptability sensory qualities of dried banana is not significantly different. Consequently, the drying temperature of 90oC was suggested as the best drying condition for sliced bananas. Moreover, three mathematical models (Newton, Logarithmic and Page) describing thin layer drying were investigated. It was found that the thin layer equation providing the highest coefficient of determination (R2) and the lowest chi-square (X2) and root mean square error (RMSE) was the Logarithmic equation.

Published: October 2019

This study evaluated the biological activity (antioxidant assay) of Polygonum minus extracted using Supercritical Fluid Extraction (SFE) added with different types of co-solvents. The seven co-solvents employed were water, methanol, ethanol, 50% methanol, 50% ethanol, 70% methanol and 70% ethanol for selection of the best co-solvent prior to optimization of SFE. 70% methanol produced the highest total yield of extract (33.1%) compared to other co-solvents. The antioxidant capacity was then evaluated using four different assays: the total phenolic content (TP), the total flavonoid content (TF), the ferric reducing/antioxidant power (FRAP) and the free radical-scavenging capacity of 2,2-diphenyl-1-picrylhydrazyl (DPPH). The highest TP and TF were from 70% methanol extract (11.2 ± 0.15 mg GAE/g sample (mg GAE/g) and 11.9 ± 0.03 mg CAE/g sample (mg CEQ/g) respectively). 70% metanol extract also showed the highest FRAP value (346.7 ± 0.66 µmol Fe (II)/g sample) and the highest percentage of DPPH radical inhibition was also shown by 70% methanol extract (88.7 ± 0.40%). There was a positive correlation between the antioxidant capacity (FRAP and DPPH) with those of TP and TF contents. Therefore, the best co-solvent chosen for further optimization of SFE is 70% methanol.

Published: October 2019

During the production process of glyphosate from n-phosponomethyl iminodiacetic acid (NPMIDA) and hydrogen peroxide (H2O2 Five grams of NPMIDA, 0.3 grams of fresh palladium catalyst, and 85 mL of H), deactivation of the catalyst used may occur, which will decrease the production of glyphosate. To controll the rate of production the deactivation process of the catalyst needs to be evaluated. 2O were put into a three neck flask. One mL of H2O2 was added into the mixture every ten minutes, so that the total amount of H2O2 The activity as a function of temperature and time can be expressed as follows: added was 9 mL. The reaction was kept going for another 15 minutes. The catalyst was filtered and its filtrate collected in a 500 mL erlenmeyer glass. The filtrate was then naturally cooled to room temperature and 130 mL of technical grade ethanol was added to it. The solution was left overnight for the crystal formation. The glyphosate crystal formed was then separated from the solution and washed with 40 mL of technical grade ethanol, followed by 40 mL of technical grade ether. Finally the glyphosate crystal was dried in open air. The amount of crystal glyphosate produced was weighed and its purity was analyzed using UV/Vis spectrophotometer. The catalyst was then reused in the next experiments using the same procedure.The activity as a function of temperature and time can be expressed as follows:φ(T,t) = α t(-n) where α = 0.027T - 7.99 and (-n) = 0.005T + 1.62. These parameters hold for temperatures (T) of 333K to 363K. At 363K, the rate of deactivation of the catalyst is the fastest. Experiments that were run at 348K resulted in higher glyphosate productivity compared to other temperatures.
System Approach from Biomass Combustion in Packed Bed Reactor
Authors: Le Anhkien , Hai Le Xuan , Sharifi V. N. , Swithenbank J.
Published: October 2019

A simple algorithm originally proposed by Choong, Paterson and Scott (2002) was tested on a model of an isothermal controlled-cycled stirred tank reactor with substrate inhibition kinetics, (r = 1 ~c). In previous work, this reacting system had been shown to exhibit steady-state multiplicity. The transition period of this system to the stable steady state is sometimes characterized by very slow change followed by a very rapid convergence to the stable steady state. Tests of the Choong-Paterson-Scott algorithm showed that the feature, which prevents premature termination of the calculations prior to reaching the true steady state, is very useful for this system. However, tests of the stopping criterion showed that the other feature of reducing the computing time was not realized in this system.

Assim foi possível comentar algumas tendências nacionais que clarificam a importante questão da imbricação do religioso na cena política do país, analisando temas como: cristianismo, conservadorismo, diversidade religiosa, estratégias políticas e representação de gênero.
Antropologia e Filosofia Política: uma relação estranha? Ou como analisar controvérsias entre cidadãos seculares e religiosos em uma democracia liberal
Authors: Mauricio Junior Cleonardo Gil de Barros , Carneiro Campos Roberta Bivar , Gusmão Eduardo Henrique de Araújo
Published: October 2019

Levando em consideração a presença constante da religião nos dilemas do século XXI, questionamos neste artigo como deve se dar a análise dos eventos que põem em rota de colisão as identidades religiosas e seculares no seio das democracias liberais. Reconhecendo que o tema em questão tem sido objeto privilegiado da Filosofia Política, pretendemos nos perguntar até onde a Antropologia, que sempre privilegiou a descrição etnográfica como modo privilegiado de conhecimento, deve acompanhar uma ciência abertamente normativa no intuito de dar conta dos inúmeros conflitos envolvendo a religião na esfera pública. Ao transpormos os termos da comparação feita por Joel Robbins entre a Antropologia e a Teologia para a nossa contraposição com a Filosofia Política, pretendemos mostrar como a Antropologia Brasileira tem assumido contornos normativos em detrimento da auto-reflexão ao encarar os dilemas de abordar o fenômeno religioso na esfera pública diante das transformações que a disciplina enfrenta.

CORPO E SENSIBILIDADE NA RELIGIÃO: COMENTÁRIOS SOBRE O TEXTO DE B. MEYER
Authors: Rabelo Miriam
Published: October 2019

O texto de Meyer,” A Estética da Persuasão: as formas sensoriais do Cristianismo Global e do Pentecostalismo” desenvolve o argumento de que um entendimento do cristianismo globalizado requer atenção não apensas para o conteúdo de sua mensagem, como também, e principalmente para a forma como a religião modela o corpo e a sensibilidade, tema que ela pretende abordar através do conceito de forma sensorial. Ao dialogar com o texto de Meyer coloco algumas questões sobre sua abordagem à sensibilidade e enfatizo a necessidade de que a entrada do corpo e da estética nos estudos antropológicos sobre religião ilumine processos abertos de criação e mudança religiosa.
POR QUE NÃO PODEMOS VER A DIVERSIDADE RELIGIOSA: QUESTIONANDO O PARADIGMA CATÓLICO-CÊNTRICO NO ESTUDO DA RELIGIÃO NA AMÉRICA LATINA
Authors: Frigerio Alejandro
Published: October 2019

Os avanços nos estudos da religião na América Latina se tornam restringidos pela persistência de visões excessivamente católicas-cêntricas que impedem a compreensão adequada à extensão e à relevância da diversidade religiosa, a relegando a um mero epifenômeno recente e minoritário da nossa realidade social. A natureza real do papel do catolicismo no continente poderia ser melhor avaliado e compreendido - nas suas diferentes dimensões - se deixarmos de aceitar sem críticas uma série de suposições e princípios básicos que orientam nossa análise e que tentarei repensar neste trabalho. Para fazer isso, procuro identificar as características mínimas do que considero um paradigma analítico dominante no estudo da religião nas ciências sociais (principalmente a sociologia) e fornecer uma visão alternativa, baseada em diferentes pressupostos teóricos. Argumento que a dependência nos postulados de alguns autores canônicos, a excessiva comparação entre "identidades" e "crenças" e a adesão a visões extremamente institucionalizadas sobre a religião, bem como a pouca atenção dada às diferentes formas de regulamentações religiosas, fornecem uma visão exagerada de uma "América Latina católica".
“HOJE À NOITE VAI TER RETETÉ, PÔ!”: EVIDÊNCIAS DE CONFLITOS COTIDIANOS EM RITUAIS PENTECOSTAIS
Authors: Guerreiro Clayton
Published: October 2019

No presente artigo, analiso conflitos protagonizados por fiéis pentecostais, supondo que são evidenciados, encenados e atualizados nos rituais pentecostais conhecidos como “reteté”. Esses rituais ocorrem principalmente em pequenas igrejas da periferia das grandes cidades brasileiras, onde ocorrem vigílias pentecostais, como o “Vigilhão da Celebrai”, que acontece periodicamente em Duque de Caxias, Rio de Janeiro. Entre os aspectos evidenciados nos rituais do “reteté”, destaco as ações simbólicas de combate às religiões afro-brasileiras, as quais aparecem em pregações, músicas, orações e gestuais e podem ser classificadas como intolerância religiosa, bem como as relações ambíguas entre evangélicos pentecostais e traficantes de “drogas”. Concluo, demonstrando que, a despeito das ações de intolerância contra as religiões de matriz africana, há pequenas ações de cooperação promovidas entre evangélicos e religiões afro-brasileiras, tais como Umbanda e Candomblé.
SONHOS DE UMA MESQUITA ICÔNICA: ENTRELAÇAMENTOS TEMPORAIS E ESPACIAIS EM UMA IGREJA CONVERTIDA DE AMSTERDÃ
Authors: Beekers Daan , Tamimi Arab Pooyan
Published: October 2019

Este artigo foca na criação de iconicidade através da arquitetura religiosa em Amsterdã, Holanda. Ao examinar a Mesquita de Fatih, abrigada em uma antiga igreja católica no centro da cidade, apresentamos de que maneiras os esforços para fazer desta uma mesquita icônica são moldados pelo terreno icônico da construção, pelo qual determinamos seu envolvimento com outros locais (religiosos e não religiosos) do passado e do presente. Esse campo icônico é caracterizado pelas cadeias de conversão que precederam a mesquita, legados materiais e discursivos de “ocultação” e interações simbólicas contemporâneas com construções próximas, como a Igreja Ocidental. Ao desenvolver uma análise dos entrelaçamentos espaciais e temporais da Mesquita com o espaço urbano de Amsterdã, buscamos revitalizar uma abordagem diacrônica e relacional que vem sendo negligenciada, principalmente em estudos sociais-científicos de mesquitas no Ocidente. Não iremos analisar um único local de devoção em um momento específico na história, mas chamaremos atenção para as relações entre o Islamismo e outras arquiteturas religiosas e para as maneiras com que as mesquitas interagem com amplas genealogias e geografias das religiões, não apenas por associação, mas também por conexões concretas de relações, política ou cultura material.

Governing climate change for sustainable food production: A case study of emerging markets
Authors: Ddamulira Robert
Published: October 2019

This article addresses three research questions: How does climate change impact food production? What are the governance challenges associated with managing such impacts? What are the conditions for future success in managing the impacts of climate change on food production? To answer these questions, the researcher undertook a document review and analysis to address these various aspects with a major focus on East Africa. The study finds that climate change affects food production largely through its physical impacts on precipitation and increased the frequency of extreme weather events. Within a context of weak governance; climate change further challenges governance institutional structures and mechanisms. The study concludes that specific aspects of the prevailing climate change governance regime require major reforms (particularly the role of the state, corporations and civil society) while other climate governance mechanisms need to be completely overhauled (for example through establishment of a new World Environment Organization).
PENGARUH PANJANG SERAT TERHADAP KEAUSAN, KEKUATAN TARIK DAN IMPACT KOMPOSIT SERAT PELEPAH PISANG BERMATRIKS POLYESTER
Authors: Sani Syaiful Anwar , Purboputro Pramuko Ilmu , Ngafwan Ngafwan
Published: October 2019

Tujuan penelitian ini adalah untuk mengetahui pengaruh antara panjang serat pelepah pisang 10 mm, 20 mm, 30 mm, 40 mm terhadap keausan, kekuatan tarik dan impact  komposit serat pelepah pisang dengan matrik polyester. Selain itu untuk meneliti jenis-jenis patahan yang terjadi pada pengujian impact dan tarik.              Pada penelitian ini serat yang digunakan adalah serat pelepah pisang kepok dengan fraksi volume 50%, panjang serat 10 mm, 20 mm, 30 mm, 40 mm. Proses pembuatan spesimen menggunakan pressmold. Jenis matrik  yang digunakan adalah polyester BQTN 157, 1% hardener. Cetakan spesimen menggunakan kaca. Standart acuan untuk pembuatan dan pengujian spesimen yang digunakan yaitu ASTM D 256 untuk pengujian impact  dan ASTM D 638-03 type I untuk pengujian tarik, serta untuk pengujian keausan menggunakan metode ’’Ogoshi High Speed Universal Wear Testing Machine’’ (type OAT-U).              Dari hasil penelitian dapat disimpulkan bahwa perbandingan panjang serat tidak begitu berpengaruh terhadap kekuatan impact. Spesimen dengan serat yang semakin panjang akan semakin tahan lama dalam menahan beban tarik karena serat yang panjang mempunyai struktur yang lebih sempurna yang terpasang sepanjang sumbu serat dan cacat internal pada serat lebih sedikit daripada material serat yang pendek. Semakin panjang serat maka tingkat keausannya semakin tinggi. Sedangkan serat yang pendek memiliki kerapatan dan kemampuan yang lebih dalam meredam gesekan dibandingkan serat yang panjang sehingga tingkat keausannya relatif rendah. Sehingga serat yang lebih pendek baik digunakan sebagai bahan kanvas rem. Jenis patahan yang terjadi adalah pull out fiber pada spesimen uji impact dan patah getas pada spesimen uji tarik.

Published: October 2019

Studi yang akan dilakukan adalah untuk mengetahui pengaruh kekasaran permukaan benda kerja pada pengelasan spot welding. Percobaan yang telah dilakukan menggunakan material baja karbon rendah dengan ketebalan 0,8 mm. Material tersebut di-treatment dalam 3 kondisi permukaan, yaitu kondisi permukaan asli, permukaan yang diamplas dan permukaan yang di-sand blasting. Parameter pengelasan yang dilakukan adalah menggunakan dua variasi yaitu arus pengelasan sebesar 3000, 4000, 5000 A, dan waktu las (welding time) selama 0,3 , 0,4 dan 0,5 detik. Selain dari itu, tekanan elektroda yang diberikan adalah konstan 150 kg.              Untuk mendukung fenomena pengelasan yang terjadi, maka dilakukan juga pengukuran hambatan listrik yang terjadi diantara sambungan las. Pengujian sambungan las yang dilakukan adalah pengujian kekuatan geser sambungan dengan standar AWS D8.9-97, serta pengujian sifat fisik sambungan las dengan uji foto mikro dan makro.              Dari hasil percobaan menunjukkan bahwa variasi arus, waktu, dan kekasaran permukaan berpengaruh signifikan terhadap kekuatan sambungan las. Sedangkan, Hasil pengamatan foto makro menunjukkan bahwa lebar logam las semakin besar seiring peningkatan arus, waktu, dan kekasaran permukaan yang berbeda.Selanjutnya, hasil uji foto mikro logam induk baja karbon rendah memiliki fasa ferit dan perlit. Pada hasil uji foto mikro daerah HAZ tetap yaitu ferit dan perlit namun dalam ukuran lebih halus dibandingkan pada logam induk. Sedangkan fasa logam las yang terbentuk adalah martensit.
ANALISA PENGARUH PERIODIK CHARGING DAN DISCHARGING PADA WAKTU CHARGING DAN DISCHARGING DARI METAL HYDRIDE REACTOR (MHR)
Authors: Syawitri Taurista Perdana
Published: October 2019

Perpindahan panas merupakan faktor penting yang mempengaruhi kinerja tangki penyimpanan hydrogen dalam bentuk metal hydride. Penelitian sebelumnya menyimpulkan bahwa penambahan sejumlah kecil metal foam pada interior metal hydride reactor (MHR) merupakan cara yang efektif untuk meningkatkan perpindahan panas pada reaktor, sehingga mengurangi waktu charging. Namun, proses charging dan discharging MHR dilakukan secara terpisah dalam studi ini. Oleh karena itu, penelitian ini menyimulasikan model 2-D axisymmetric menggunakan software COMSOL untuk menginvestigasi pengaruh dari periodik charging dan discharging dari MHR yang mengandung metal foam dengan fraksi volume tertentu. Hasil simulasi menunjukkan bahwa model saat ini mempunyai hasil yang sesuai dengan hasil yang ditunjukkan di dalam literatur. Selain itu, ditemukan bahwa terdapat nilai optimum dari fraksi volume metal foam di setiap proses charging dan proses discharging yang memberikan waktu charging dan discharging lebih pendek.

Authors: Supriyono Supriyono
Published: October 2019

The aim of this research is to study the effects of pack carburizing using charcoal on properties of mild steel. The properties are represented by the results of microstructure, hardness test and tensile test.  The carburizing process was conducted in the temperature of 930oC which is the austenite temperature of the mild steel. The source of carbon was charcoal. The specimens were held for 2, 3 and 4 hours at the carburizing temperature. The carbon content of the raw amterial was 0.17%. The raw material was hypoeutectoid steel with ferrite and pearlite phases in its microstructure.  After the carburizing process, the microstructure can be divided into two zones e.i. case zone and core zone. The case zone consists of hypereutectoid, eutectoid, and hypoeutectoid sub-zone. The core zone is the same as raw material. The longer the holding time will result in the deeper the case zone and the stronger the material.
ANALISIS KEAUSAN PADA DINDING SILINDER MESIN DIESEL
Authors: Tjahjono Tri
Published: October 2019

Silinder adalah bagian dari ruang bakar mesin Diesel yang penting karena silinder merupakan tempat terjadinya pembakaran bahan bakar dengan udara dan juga alur gerak bolak-balik piston. Akibat gerakan tersebut akan terjadi gesekan antara silinder dan cincin piston yang menyebabkan keausan pada dinding silinder. Keausan tersebut mengakibatkan ukuran silinder menjadi besar sehingga penyekatan ruang bakar menjadi kurang bahkan menjadi bocor. Hal ini akan menyebabkan mesin Diesel tidak bertenaga atau tidak jalan sama sekali.

Published: October 2019

A fluência é uma habilidade que envolve a participação de múltiplos sistemas neurais, principalmente, dos processamentos da linguagem, fala, voz e audição. Tais interfaces justificam a necessidade de considerar na dinâmica avaliativa fonoaudiológica, suas interações com os demais conteúdos específicos da Fonoaudiologia. O presente artigo de cunho teórico, consiste em uma revisão não-sistemática da literatura que objetiva discutir acerca do processo de avaliação fonoaudiológica da fluência, mediante uma perspectiva de integralidade do cuidado. Tal discussão visa contribuir para a consolidação do caráter transversal da fluência na literatura nacional, coerente com a complexidade da sua natureza neurofisiológica; bem como favorecer ao fonoaudiólogo, informações e reflexões necessárias para a sua aplicabilidade em contexto prático. Para isso, estruturou-se esta comunicação em duas principais seções: apresentação do processo de avaliação da fluência, e discussão acerca da avaliação integrada da fluência. Dessa forma, conclui-se que, para uma avaliação fonoaudiológica integrada da fluência é necessário ir além da identificação das rupturas e realização dos cálculos de velocidade de fala. Requer conhecimento aprofundado sobre a natureza da fluência, enquanto habilidade e área da Fonoaudiologia, para o exercício do raciocínio clínico integrado que contemple a unicidade de cada sujeito, bem como suas necessidades comunicativas para além da queixa, vislumbrando a saúde da sua comunicação.

Authors: Halberstadt Bianca Fraga , Moraes Anaelena Bragança de , Souza Ana Paula Ramos de
Published: October 2019

Introdução: A chegada de um filho com deficiência traz muitos desafios aos familiares podendo impactar na funcionalidade da criança. A visão que a família possui da criança nem sempre condiz tanto com suas potencialidades quanto com déficits. Por isso, interessa comparar a visão dos pais e terapeutas da criança. Objetivo: Comparar a visão dos pais e dos terapeutas em relação à funcionalidade de crianças com Síndrome de Down (SD). Métodos: Trata-se de um estudo qualitativo, de amostra por conveniência, com três crianças com SD, seus pais e terapeutas. A coleta de dados se deu por meio da aplicação da CIF-CJ com um dos responsáveis da criança e com a terapeuta estagiária responsável por cada caso, todos atendidos em clínica-escola de Fonoaudiologia. Resultados: Após análise dos três casos observou-se que a diferença nas respostas entre familiares e terapeutas esteve concentrada na percepção da linguagem das crianças, sobretudo em relação à fala. Também se observou que os terapeutas percebem a relação dos familiares com os profissionais de saúde mais frágeis do que os pais. Os resultados reforçam a importância sobre um olhar sobre a funcionalidade na clínica da infância. Conclusão: Na comparação da funcionalidade na percepção de pais e terapeutas, destacou-se a diferença na percepção da produção linguística das crianças.
Pohjoissaamen adnominaaliset demonstratiivipronominit nuorten radiokeskusteluissa
Authors: Guttorm Outi
Published: October 2019

Tarkastelen tässä artikkelissa pohjoissaamen demonstratiivipronominien, erityisesti adnominaalisten pronominien dát ’tämä’ ja diet ’se (siinä)’ endoforista käyttöä nuorten puhekielessä. Tarkoituksenani on selvittää miten pronomineja käytetään ja mihin niillä viitataan nuorten radiokeskusteluissa, joissa viittaaminen näköpiirissä oleviin konkreettisiin tarkoitteisiin ei ole ensisijaista. Pohdin myös pronominien keskinäisiä eroja ja tehtäviä keskustelussa. Tutkimusaineisto on Norjan yleisradioyhtiö NRK:n saamenkielisistä nuortenohjelmista. Siinä endoforisina pronomineina esiintyvät dat ’se’, diet ’se (siinä) ja dát ’tämä’. Selkeästi yleisin anaforinen pronomini on dat. Radiokeskusteluissa diet-pronominilla viitataan erityisesti johonkin, josta on edellä kuultu. Sillä viitataan myös tarkoitteeseen, joka esiintyy toisessa yhteydessä, tai keskustelukumppanin mainitsemaan asiaan. Dát-pronomini puolestaan nostaa tarkoitteen erityiseen fokukseen. Se on myös yleisin kataforinen pronomini. Tutkimus täydentää ja tarkentaa kielioppien aiempia näkemyksiä pohjoissaamen demonstratiivien käytöstä ja merkityksestä.

However, there is a noticeable participation reluctance among English major student-teachers in the College of Ed-ucation at Kuwait University. The present study investigates the causes of such a reluc-tance. The study adopted the descriptive analytical methodology applying a 4-Likert scale to respond to a thirty questionnaire items. Two domains were covered: the English language professor, and the English major student-teachers. The sample covered a total of 150 English major student-teachers 30 males and 120 females. The study revealed significant differences α=0.05 in the means between the participants according to gender in favor of females-student teachers and according to high school specialization in favor of Arts specialization. However, there were no significant differences according to the years of study.
Reducing off -Task Behaviors Using an Action Research Method with One-Case Study
Authors: Jaffal Abeer
Published: October 2019

The purpose of this action research project was to discover what interventions would be most effective in decreasing the off-task behaviors of a student. Interventions used were use of a token system, changes in classroom environment and teacher attention. The sample selected for this research was a student in a second-grade classroom. This action research grew out of the frustration and sense of inadequacy of a teacher attempting to deal with the off-task behaviors of one of her students. The student’s off task behaviors were interfering with her learning and that of her classmates. There were seven specific off-task behaviors that helped define the problem. These behaviors included daydreaming, speaking to peers, talking out of turn, touching others, fidgeting with objects, getting out of her seat at inappropriate times, and putting her head down on the table. The three tools that were chosen to document evidence of the problem were an observation checklist, a student survey and a teacher survey. The findings indicated that allowing the subject to enjoy one of her favorite activities, contingent upon a decrease in the off-task behaviors, was effective in maintaining the desired behavior of staying on-task and decreasing inappropriate behaviors.

Authors: Oliveira Sávio Ribeiro , Alvarenga Altair Resende de
Published: October 2019

O Supremo Tribunal Federal, no julgamento do Habeas Corpus nº 126.292, ao interpretar o artigo 5º, inciso LVII, da Constituição da República/1988, entendeu que aquelas pessoas condenadas em segunda instância deveriam iniciar, após esse momento e antes do trânsito em julgado, o cumprimento da pena. A partir daí, surgiu inúmeras controvérsias, entre os operadores do direito, versando sobre a execução provisória da pena. No presente artigo, será feito um estudo acerca da finalidade precípua do princípio da presunção de inocência sob a perspectiva de toda a sistemática constitucional e a unicidade do ordenamento legal, a fim de se analisar a conformação da posição adotada pela Suprema Corte ao ordenamento jurídico pátrio. Em seguida, será analisado o momento em que o efeito secundário extrapenal da perda do cargo, função pública ou mandato eletivo deverá ocorrer, se após a condenação em segunda instância, ou se deverá aguardar o trânsito em julgado da condenação.

Published: October 2019

Penelitian ini bertujuan untuk menjelaskan kesesuaian sistem pelaporan keuangan pemerintah berbasis cash toward acrual dan full accrual dan relevansinya dengan pengambilan keputusan internal organisasi pemerintah. Selain itu, penelitian ini juga mengidentifikasi peran pengendalian internal dalam pelaporan keuangan pemerintah daerah. Desain penelitian adalah survey dengan responden pelaksana akuntansi pemerintah daerah di Provinsi Jawa Timur dan Sulawesi Barat. Hasil penelitian menunjukkan bahwa sistem pelaporan keuangan pemerintah berbasis full accrual mempunyai kesesuaian dalam menyediakan informasi untuk pengambilan keputusan internal di provinsi tersebut. Namun demikian, tingkat kesesuaian sistem pelaporan keuangan pemerintah berbasis full accrual lebih rendah dibanding dengan basis cash toward accrual. Selain itu, baik pengawasan internal maupun relevansi informasi pelaporan keuangan memiliki peran penting di kedua provinsi dalam konteks pengambilan keputusan internal. Hasil ini berimplikasi bagi pemerintah daerah untuk meningkatkan kualitas dan kapabilitas internal pemerintah serta kualitas implementasi basis akrual dalam akuntansi pemerintah daerah agar informasi dalam laporan keuangan pemerintah lebih relevan dalam pengambilan keputusan internal.

Herein, we report that iron(II)/ammonium persulfate in aqueous acetonitrile mediates the Newman-Kwart rearrangement of O-aryl carbamothioates. Electron-rich substrates react rapidly under moderate heating to afford the rearranged products in excellent yields. The mild conditions, rapid reaction rates, and suitability for scale up offer immediate practical benefits to access functionalised thiophenols.
A Bis-Monophospholyl Dysprosium Cation Showing Magnetic Hysteresis at 48 Kelvin
Authors: Evans Peter , Reta Daniel , F. S. Whitehead George , Chilton Nicholas , Mills David
Published: October 2019

Single-molecule magnets (SMMs) have potential applications in high-density data storage, but magnetic relaxation times at elevated temperatures must be increased to make them practically useful. Bis-cyclopentadienyl lanthanide sandwich complexes have emerged as the leading candidates for SMMs that show magnetic memory at liquid nitrogen temperatures, but the relaxation mechanisms mediated by aromatic C5 rings have not been fully established. Here we synthesise a bis-monophospholyl dysprosium SMM [Dy(Dtp)2][Al{OC(CF3)3}4] (1, Dtp = {P(CtBuCMe)2}) by the treatment of in situ-prepared “[Dy(Dtp)2(C3H5)]” with [HNEt3][Al{OC(CF3)3}4]. SQUID magnetometry reveals that 1 has an effective barrier to magnetisation reversal of 1,760 K (1,223 cm–1) and magnetic hysteresis up to 48 K. Ab initio calculation of the spin dynamics reveal that transitions out of the ground state are slower in 1 than in the first reported dysprosocenium SMM, [Dy(Cpttt)2][B(C6F5)4] (Cpttt = C5H2tBu3-1,2,4), however relaxation is faster in 1 overall due to the compression of electronic energies and to vibrational modes being brought on-resonance by the chemical and structural changes introduced by the bis-Dtp framework. With the preparation and analysis of 1 we are thus able to further refine our understanding of relaxation processes operating in bis-C5/C4P sandwich lanthanide SMMs, which is the necessary first step towards rationally achieving higher magnetic blocking temperatures in these systems in future.
