An Improved Method to Calculate the Conservation of Mass in the Simulation of Rapid Pressurization Depressurization in a Packed Bed
Authors: Chong Thomas S.Y , Paterson William R. , Scott David M.
Published: October 2019

The work described here forms part of a project to model rapid pressure swing adsorption (RPSA), which is a single-bed process used for air separation. We have earlier identified a form of model and boundary conditions for an axially dispersed plug flow model that conserves mass. We solve the RPSA models numerically by spatially discretizing the partial differential equations to a system of ordinary differential equations (ODEs), which are then integrated over time. Although the formulation of our models conserves mass, our numerical simulations, however, do not perfectly conserve mass because of discretization error and rounding error. The discrepancy in the conservation of mass is computed as a guide to the numerical accuracy of the calculations. The computation of the conservation error requires the evaluation of time integrals of molar flowrates in and out of the bed. Since the velocity at the feed end of the bed changes rapidly with time, the application of quadrature to evaluate the time integrals does not provide the accuracy required. In this paper, the inadequacy is demonstrated using a simple problem, i.e. pressurization and depressurization into a non-adsorptive bed. An improved method is proposed. By transforming equations involving time integrals into ODEs, excellent accuracy is obtained. Further, this transformation minimizes the number of decision parameters that need to be specified by the users of the computer programs. Keywords: rapid pressure swing adsorption, modelling and simulation, packed bed.
Effects of Shear Rate on Morphology and Gas Separation Performance as Asymetric Polysulfone Membranes
Authors: Ismail Ahmad Fauzi , Yean Lai Ping
Published: October 2019

Asymmetric polysulfone flat sheet membranes have been produced by a dry/wet casting technique. The membranes were produced at different shear rate. Gas permeation properties were examined using pure hydrogen and nitrogen as test gases. Infrared dichroism was detected in all samples, the extent being greater in the high shear membranes. This suggests that the polymer molecules become aligned under high shear. Gas separation tests showed that the higher shear membranes exhibited greater selectivity (H!Nz)' Some of the membrane selectivities even surpass the intrinsic selectivity of the membrane polymer. Increasing shear rate during casting had decreased skin layer thickness and thus increased pressure-normalized flux. High-shear casting also enhances the molecular orientation in skin layer and, in turn, heighten selectivity of membrane. Therefore, correlation of rheological aspects with primary phase inversion parameters provides a potential platform to develop high performance asymmetric polysulfone membranes for gas separation.Key words: asymmetric membranes, gas separation, rheology, molecular orientation, super-selective, polysulfone
Measuring and Modeling the Performance of Rigid Ceramic Filters
Authors: Chuah M T. G. , Seville J. P.K
Published: October 2019

Rigid ceramic filters have been proven to be highly efficient gas filtration devices. However, they must be cleaned periodically for maximum efficiency. This is done by applying a pulsed reverse flow. The cleaning mechanism by which the deposited dirt is removed from the filter surface is still not fully understood. Experiments were carried out to measure pressure drop along the axis of two different candle geometry, cylindrical and tapered. For the cylindrical filter, the reverse pulse pressure was not uniformly distributed along the element. Generally, the pressure difference across the wall of the element is highest at the close end, and lowest, sometimes close to zero, at the open end. Pressure drop across the tapered filter was more uniform compared to that of the cylindrical filter. Hence, it should demonstrate better filter dirt removal. The authors have written a computer program that models the flow of the reverse pulse from the cleaning bar nozzle to the dirty side of the filter. It uses the iterative calculation mode and allows variables such as reverse pulse pressure and filter geometry to be changed. The calculations demonstrate fair agreement with the experimental results.

A simple module for surface area measurement based on CO2 adsorbtion.at dry-ice methanol temperrature was designed. The designed consists a sample tube, a glass syiringe for pressure measurement, and an anspirator for evacuation. No shopiscate electronic de w used. Dry ice was used Dry ice was coolent in place of liquid nitrogen, which is widely wed in ordinary BET surface area measument. Vacuum tighess w confied acceptable when cooking oil was used a seal liquid at the contact suace of the singe. Error anaIes were done for both vacuum tighness and the prence of riduaI gases due to the use of water-driven aspiration. Adsorbtion measurements of CO2 were conducted using the simple module and a conventional apparatus. Results confirmed that the modue works well within reasonable eximental error, if the weight of sampIe and the initial intake of sample gas are chosen properly. However since the adsorption isotherms of several carbon samples shawed a pleteau at high preure, the BET equation was not applicble.

Impact of Cognitive Behavioral Therapy on Resting Cardiac Parameters and Cortisol in Patients with Post-Traumatic Stress Disorder: A Pilot Randomized Clinical Trial
Authors: Gonçalves Raquel Menezes , Norte Carlos Eduardo , Souza Gabriela Guerra Leal , Volchan Eliane , Coutinho Evandro Silva Freire , Figueira Ivan , Ventura Paula
Published: October 2019

Post-Traumatic Stress Disorder (PTSD) has been associated with changes in psychophysiological and neuroendocrinal parameters. Cognitive Behavioral Therapy (CBT) is considered the treatment of choice for PTSD and is able to regularize altered neurobiological parameters; however, little is known about its effects on these parameters when measured during the therapeutic process. This pilot study aimed to evaluate the impact of CBT on cortisol and cardiac parameters measured at rest during the treatment of PTSD with comorbid major depression. 14 patients were randomized to four months of CBT or a waiting list. As expected, the experimental group had a greater reduction in PTSD symptoms and a large effect size. There was a reduction in the low frequency component of heart rate variability, which achieved borderline statistical significance and a large effect size. Salivary cortisol tended to track the progress of therapy, rising in the period of exposure and decreasing by the end of treatment. Despite the small sample size, this study opens the way for further research into the impact of CBT on the different biological markers of PTSD during the therapeutic process. This can hopefully help to optimize and personalize therapeutic studies while providing clues about modifications in bio behavioral pathological manifestations.
As faces de Deus: Um estudo exploratório com crianças e adolescentes
Authors: Ricardo Lorena Santos , Ortega Antônio Carlos , Alencar Heloisa Moulin de
Published: October 2019

As representações sobre Deus são elaboradas com o mesmo objetivo que o são todas as representações sobre as quais versa o conhecimento social (organizar, explicar e significar o que ocorre em seu meio). Assim, objetivou-se investigar as representações de crianças e adolescentes acerca de Deus, por meio de entrevistas baseadas no método clínico piagetiano, com sujeitos de 6, 10 e 14 anos. Foram elaborados critérios para análise das repostas, baseados no trabalho de Delval e Muriá (2008), de forma a permitir identificar diferentes níveis de elaboração dessa representação. Os resultados não apresentam diferenças relevantes entre as idades em relação ao nível da representação de Deus. Contudo, colaboram com as discussões acerca da construção de tais representações. Novas pesquisas se fazem necessárias com um número maior de participantes e uma amostra mais homogeneizada, a fim de identificar as variáveis que podem influenciar o processo de construção do conceito de Deus.

ZONAS FRONTEIRIÇAS: ÉTICA, ETNOGRAFIA E O CRISTIANISMO “REPUGNANTE”
Authors: Coleman Simon
Published: October 2019

Investigo, neste estudo, o relacionamento problemático entre a antro-

pologia e o cristianismo conservador, representado pelo Pentecostalismo ligado à Teologia da Prosperidade. Meu interesse não está apenas nos complexos limites erigidos entre a prática social científica e a religiosa, mas também nas formas como ambas envolvem a construção de orientações éticas para o mundo, orientações essas que são persistentemente construídas pela implantação de fronteiras que atuam entre o primeiro e o segundo plano da perspectiva ética. Uma das implicações do meu argumento é que precisamos prestar mais atenção na temporalidade do enquadramento ético da ação. A outra é que a antropologia deve reconhecer o aspecto fragmentado, e até mesmo irônico e lúdico, da prática pentecostal.
A QUEDA NO ESPÍRITO SANTO SEGUNDO OS KAINGANG
Authors: Sene de Lourenço Marília
Published: October 2019

Este ensaio fotográfico aborda um fenômeno comum aos rituais das

igrejas pentecostais de vertente contemporânea (chamadas “neopentecostais” por alguns autores), a Queda no Espírito Santo. Trata-se da perda da consciência de um fiel por meio do toque das mãos de um profeta em seu corpo – no local exato de suas chagas e/ou em sua testa – com a finalidade de curá-lo. Etnografei esse fenômeno como parte de alguns cultos evangélicos de aldeias Kaingang localizadas na região do Alto Uruguai (Brasil meridional), coletividades cuja predileção pelas igrejas pentecostais pode ser considerada massiva na atualidade. A Queda no Espírito Santo parece resultar do aquecimento do ritual, enfatizado pela presença

de especialistas religiosos não indígenas, convidados cujas ações geram condições ideais para essa forma particular de êxtase religioso.
ESTÉTICA PARA QUEM? SOBRE O PÚBLICO DA PERSUASÃO PENTECOSTAL
Authors: Blanes Ruy
Published: October 2019

Neste texto abordo a noção de “estética da persuasão” formulada por Birgit Meyer. Explorando a dimensão distributiva da estética presente na sua tese, argumento que o “lugar” da religião é um espaço de relacionalidades exteriorizações que deverá incluir tanto crentes como não crentes, os espaços de culto e as suas vizinhanças seculares, configurando um “público” que excede o religioso. Para tal, Utilizo como termo de comparação empírico o meu trabalho de campo sobre pluralismo religioso no bairro do Palanca, em Luanda (Angola).
LOS MAPAS DIVERSOS DE LA DEVOCIÓN A LA VIRGEN DE URKUPIÑA EN LA CIUDAD DE SALTA - ARGENTINA
Authors: Nava Le Favi Daniela
Published: October 2019

El culto a la Virgen de Urkupiña tiene sus orígenes en Cochabamba –Bolivia- y, en los últimos años, ha llegado a la Argentina a través de migrantes bolivianos. En la ciudad de Salta, la devoción activa prácticas andinas, alejadas a lo establecido por el canon católico, sumando creyentes a una velocidad casi geométrica e inscribiéndose de múltiples formas en el territorio local.

El análisis se inscribe en una mirada interdisciplinaria para explorar los mapas que construyen las prácticas de los devotos, prestando atención a las industrias del creer paralelas que se encuentran en expansión en el macro-centro local. En contraposición, se indagan algunas estrategias de la Iglesia Católica Salteña y el municipio por disciplinar y centralizar el culto. Este recorrido cartográfico, permite pensar los múltiples sentidos de ciudad que se disputan a partir de una forma de religiosidad mariana rizomática, fronteriza, migrante y asimilada por familias citadinas.
IL GIUDIZIO UNIVERSALE: AS GRAFIAS DA DOR NA CAPELA SISTINA
Authors: Ramos Saldanha Marcelo
Published: October 2019

O presente artigo pretende identificar a teologia imagética do artista florentino Michelangelo Buonarroti, que foi cristalizada na iconografia dos afrescos sistinos, em especial, no afresco do altar denominado Il Giudizio Universal. A partir de uma análise desses afrescos, busco compreender como a dor, decorrente da elaboração quase solitária da pintura, em meio à instabilidade teológica e social do período, marcou sua forma de ler o mundo e a sua relação com o sagrado, permitindo que as ideias das reformas protestantes, lidas a partir do movimento reformista italiano denominado de Spirituali, fossem grafadas no principal templo da cristandade.
AGENTES PARAECLESIAIS: A VIRGEM DE SÃO JOÃO DOS LAGOS E SUA PEREGRINAÇÃO POR UM BAIRRO DE GUANAJUATO
Authors: Suarez Hugo José
Published: October 2019

Este artigo analisa um agente paraeclesial, no México, que se caracteriza por administrar os bens de salvação sem pertencer oficialmente à estrutura eclesial Católica. Relatamos aqui o caso de Seu Francisco, responsável pela Virgem de São João dos Lagos, que circula pelas casas de um bairro popular em Guanajuato, realizando pequenas peregrinações e rezas durante o trânsito entre uma casa e outra. Esse ritual é o que marca o ritmo da vida religiosa do lugar, para além das atividades oficiais oferecidas na Paróquia. A presença destas formas semiautônomas é um indicador das novas demandas da Fé e da recomposição do cenário religioso no México.

“ANIMISMO” REVISITADO: PESSOA, MEIO AMBIENTE E EPISTEMOLOGIA RELACIONAL
Authors: Bird-David Nurit , Viveiros de Castro Eduardo , Hornborg Alf , Rival Laura , Sandstorm Alan , Pálsson Gísli , Ingold Tim
Published: October 2019

O animismo se projeta na literatura como uma religião simples e uma epistemologia falha, em grande medida porque até hoje foi visto a partir perspectivas modernistas. Neste artigo, teorias da antropologia, das clássicas às mais contemporâneas, são criticadas. A partir do caso etnográfico de um povo caçador coletor, explora-se como funcionam as ideias animistas no contexto das práticas sociais, com atenção às construções locais de pessoa relacional e suas relações com as percepções ecológicas do meio ambiente. Oferece-se uma reformulação do animismo enquanto uma epistemologia relacional.

CONVERSÃO DO MARIDO ESPIRITUAL: A REALIZAÇÃO DA IMAGINAÇÃO PENTECOSTAL EM MOÇAMBIQUE
Authors: Van de Kamp Linda
Published: October 2019

Mulheres moçambicanas que frequentam os cultos das igrejas pentecostais brasileiras na capital de Maputo dizem ser atormentadas por um espírito violento com quem elas estariam casadas. Este espírito de vingança é frequentemente relacionado a ocorrências de guerras no passado e a um tipo de feitiçaria na qual membros da família doam ou vendem uma virgem a um espírito que vai trazer riqueza à família. Esta contribuição sugere que o número elevado de maridos espirituais em Maputo atesta as relações complexas entre parentes, namorados, casais e entre humanos e espíritos na sociedade moçambicana contemporânea em consequência de uma longa história de guerras, migrações, o colonialismo português e transformações socioeconômicas recentes. No entanto, as mulheres pentecostais entram numa nova guerra espiritual Pentecostal, na qual devem lutar contra espíritos, parentes e maridos. Desse modo, o artigo mostra a significação dos sinais espirituais nas vidas das mulheres pentecostais Moçambicanas, não só como uma imaginação passiva ou experiência espiritual, mas também como força ativa no sentido de que essas mulheres incorporam os sinais pentecostais para lutar contra o poder do marido espiritual sobre suas vidas e para realizar uma nova vida.
BUDISTAS EN MÉXICO. UNA APROXIMACIÓN DESDE LAS ESTADÍSTICAS CENSALES
Authors: May May Ezer
Published: October 2019

Los estudios del budismo en México son escasos, apenas se encuentra en su fase embrionaria. Por tanto, acercarnos a los datos censales resulta básico e imprescindible para analizar algunos aspectos de la implantación de la religión budista. Para cumplir este objetivo, expongo el perfil socio-demográfico de los budistas. Con base en las estadísticas reflexiono en torno a la identidad e identificación religiosa desde una perspectiva histórica, así también sobre su distribución geográfica, nativización, feminización y otras tendencias demográficas con el fin de entender sus implicaciones sociales. A pesar de las deficiencias del método censal para explicar los fenómenos religiosos, es una ventana que se puede abrir para tener un acercamiento al budismo en México, religión no considerada hasta ahora como significativa en términos cuantitativos.

Published: October 2019

A manifestação de uma entidade de umbanda, ao vivo, em dois programas de auditório, desencadeou em membros da plateia e em alguns telespectadores o estado de transe. A imprensa, a Igreja Católica e o Estado posicionaram-se publicamente e por meio de medidas institucionais a fim de que o fenômeno não ocorresse novamente. O caso da entidade Exu Seu Sete da Lira converteu-se em anedota, ocorrência extravagante cuja instância explanatória é disputada por discursos sociológicos, psiquiátricos e jurídicos. Nosso objetivo é descrever o caso e retomar uma discussão com os trabalhos científicos que sobre ele se debruçaram, a fim de demonstrar que o fenômeno deve ser explicado por si mesmo, pela sua presença e formas de presentificação, sendo os anteriores métodos explanatórios precários para a análise das relações entre mídia, dom espiritual e instituições estatais.

Published: October 2019

Salah satu penyebab retak muncul di struktur biasanya berawal pada daerah yang mengalami konsentrasi tegangan yang tinggi. Jika pembebanan terus dilakukan maka retak akan terus tumbuh dan menjalar sehingga menyebabkan terjadinya kegagalan. Oleh karena itu, diperlukan suatu cara atau metode yang efektif untuk menahan laju pertumbuhan retak sebelum kegagalan terjadi. Pada penelitian ini akan dilakukan kajian secara eksperimental pengaruh lasan, dimensi pengaku dan jumlah pengaku terhadap beban kritis sebelum retak menjalar. Dari penelitian yang telah dilakukan dapat disimpulkan bahwa pengaku yang diberikan sangat efektif mempengaruhi laju perambatan retak. Selain itu, dimensi pengaku mempengaruhi penghambatan penjalaran retak dimana semakin besar dimensi pengaku maka rata rata beban kritis yang dibutuhkan untuk retak mulai menjalar semakin besar. Sementara itu kualitaspengelasan pada retak sangat mempengaruhi penghambatan retak untuk menjalar.

Authors: Achmad Syaefudin
Published: October 2019

Salah satu faktor yang menentukan tercapainya tujuan pendidikan adalah pembelajaran. Pembelajaran yang baik bisa memberikan pengaruh positif terhadap peserta didik. Di antara model pembelajaran yang bisa menjadi alternatif adalah pembelajaran yang berdasar pendekatan integrtif-inklusif. Tujuan dari model pembelajaran ini adalah agar peserta didik mampu mengintegrasikan materi agama dengan sains, serta memiliki kepribadian yang inklusif, moderat, toleran, dan saling menghargai antar sesama. Tujuan ini sangat penting karena Indonesia adalah segara yang terdiri dari beraneka ragam suku, bahasa, adat istiadat, dan agama. Pembelajaran melalui pendekatan intgratif-inklusif bisa dilakukan dalam mata pelajaran Qurâ€™an Hadits di Madrasah Aliyah (MA). Qurâ€™an Hadits adalah mata pelajaran yang penting karena membahas tentang sumber ajaran Islam. Selain itu, peserta didik di Madrasah Aliyah (MA) sudah mulai berpikir kritis, serta mampu dibawa ke dalam model pembelajaran yang integratif-inklusif.

WELL BEGUN IS HALF DONE: KEEPING THE SPARKS FLYING DURING ENGLISH LESSONS
Authors: Suwartono Tono
Published: October 2019

Opening plays a very crucial period in the course of a lesson. Just like other expressions to illustrate the energy it gives, the analogies could be â€œLove at the first sightâ€, or, â€œFirst impression (of you) is so exciting, the rest is up to youâ€. Lessons opening, when it is made beneficial to the students, serves as a fire trigger, providing them with strong power at the start, and sustains â€œeternal flameâ€ till the end of the lesson. This article argues the rationale behind it and presents some ways of creating such lessons opening in the context of English language teaching.

Drama instruction is one of the methods recommended in EFL literature. This study aimed to investigate the impact of drama instruction on EFL fifth graders’ reading comprehension. It also explored the students’ and the teacher’s perceptions of the use of drama in reading lessons. A total of 74 randomly selected students participated in the study and formed the control group and the experimental group. The study followed the mixed quasi-experimental design. A pre- and posttest reading test was administered to examine the impact of drama on reading comprehension. A questionnaire was implemented to explore students’ perceptions of drama. Semi-structured interviews were also conducted to probe students’ and teacher’s perceptions of drama. The results were quantitatively and qualitatively analyzed. They showed no significant difference in reading comprehension between the control group and the experimental group. However, the experimental group performed better in the posttest than the control group although their mean scores in the pretest were lower. The participant teacher and students responded positively towards the use of drama in reading lessons. They reported that drama activities were exciting and made them love reading.

This paper focuses on investigating students’ reasons for their reluctance to attend faculty members’ office hours. Study participants included 500 male and female students from the Colleges of Engineering (n = 248) and Arts and Social Sciences (CASS) (n = 252) at Sultan Qaboos University (SQU). The study followed a descriptive-analytical approach, and a questionnaire was utilized to collect people’s views. The results of the study indicate that the rates of SQU students’ attendance to office hours were low, and some students (11.2%) do not attend at all as they consider these office hours a waste of time. The main reasons behind the students’ lack of interest in office hours were busy student timetables, conflicts between faculty office hours and students’ timetables, and easier and faster ways of getting information than visiting faculty members. Additional reasons were related to faculty members’ personalities and their discouraging attitudes toward attending office hours. The researchers recommend that SQU adopt a new strategy for encouraging faculty members to hold office hours, familiarizing students with the importance of office hours and assigning part of a course’s grades to meeting with faculty members’ office hours.

One of the phenomena of transportation problem currentl.y is the congestion which cxrurs at highwaybottlenecks. Congestion is detennined btJ the low capacity at the bottleneck point compared to theentrance rood segment before the bottleneck. This capacity reduction can be inft~d by the decrease inthe number of traffic lanes, the reduced width of rood shoulders and traffic signs.Location of the study is on a signaHzed intersection (MT Haryano Street) and unsignalized intersection(Cilincing Street). Traffic congestion Analysis is caused bi; the bottleneck based on the principle dinamictraffic with deterministic queuing method (DQA).There are three point of conclusion based on the analysis is determined queuing length, the queuing rate,Physical. diagram discharging. Firstly, queuing length are in the signalized intersection is 5.98 km andunsignalized intersection is 38.01 km. Secandl.y, queuing rate of rehicles produced by the method DQAat signalized intersection of 10,075 pcu smaller than the maximum cumulative volume at the intersection(19,900 pcu). Finally, Pln;siml diagram discharging rate is means when congestion cxrurs untilqueue missing (during t2). The Physical. diagram discharging rate at signalized intersection is 19.01km;hour and unsignalized intersection is only 4.15 km/ hour. From those amclusions show the queueinglength will increase the queuing rate and reduce congestion at the existing speed.
