Assessing Refugee Poverty Using Capabilities Versus Commodities: The Case of Afghans in Iran
Authors: Naseh Mitra , Potocky Miriam , Burke Shanna L. , Stuart Paul H.
Published: October 2018

This study is among the first to calculate poverty among one of the world’s largest refugee populations, Afghans in Iran. More importantly, it is one of the first to use capability and monetary approaches to provide a comprehensive perspective on Afghan refugees’ poverty. We estimated poverty using data collected from a sample of 2,034 refugee households in 2011 in Iran. We utilized basic needs poverty lines and the World Bank’s absolute international poverty line for our monetary poverty analyses and the global Multidimensional Poverty Index (MPI) for our capability analyses of poverty. Findings show that nearly half of the Afghan households were income-poor, approximately two percent of the households had less than USD 1.25 per person per day, and about 28% of the surveyed households were multidimensionally deprived. Results suggest that 60% of the income-poor households were not deprived from minimal education, health, and standards of living based on the MPI criteria, and about 32% of the multidimensionally deprived households were not income-poor. These findings call for more attention to poverty measurement methods, specifically for social workers and policy makers in the field, to gain a more realistic understanding about refugees’ wellbeing.

Authors: Pryce Julia , Kelly Michael S. , Lawinger Mary , Wildman Anne
Published: October 2018

This paper evaluates Conversation Club, a Canadian after-school group mentoring intervention focusing on the expansion of the program across three separate regions of Ontario. The authors use a multiple methods design, including questionnaires (n=101), post-session process data, and qualitative interviews (n=18), to evaluate how Conversation Club impacts members’ feelings of hope, belonging, sense of ethnic identity, and social support. A focus group (n = 7) with program facilitators was also conducted to explore the process of dissemination of the Club across regions. Findings suggest that Conversation Club holds promise for newcomer youth across settings. Quantitative data showed significant change (p <.01) in levels of hope and sense of belonging. Interviews revealed an increased sense of belonging, possibility, and social support, as well as improved confidence in communicating with others. Insights regarding use of the Club manual suggest the importance of integrating Conversation Club values with flexibility in facilitation to incorporate the strengths and opportunities of context across regions. Study limitations, as well as implications for further social work research and dissemination of best practices in services for migrant and refugee youth, are discussed.
Using Structural Social Work Theory to Drive Anti-Oppressive Practice With Latino Immigrants
Authors: Carrillo Arturo , O'Grady Cailtin L.

Using Structural Social Work Theory to Drive Anti-Oppressive Practice With Latino ImmigrantsArturo CarrilloCaitlin L. O'GradyAbstract: Social work practice with marginalized populations not only requires intervention to address individuals’ immediate service needs, but also requires intervention to address the larger structural context that impacts well-being. Critical theoretical frameworks, such as Structural Social Work (SSW) theory, are essential in helping social workers to develop a comprehensive understanding of the manner in which social systems are intentionally designed to oppress marginalized populations, including immigrant and refugee communities. SSW serves to both understand how society’s structure causes social problems and to identify how these structures must be changed in order to alleviate harm. Focusing specifically on Latino immigrants, this article presents an overview of SSW theory and discusses its relevance to social work practitioners. This SSW framework will then be applied to analyze two U.S. social systems, the labor regulatory and mental health systems, that are integrally connected to Latino immigrant well-being. Finally, drawing from two case examples of research conducted in Chicago, alternative models of practice in the realms of labor and mental health are presented. Findings from these case examples illustrate how social workers can engage in anti-oppressive practice when they implement interventions that promote personal healing while simultaneously challenging oppressive elements of social systems.
Challenges to Family Unity and Opportunities for Promoting Child Welfare in an Increasingly Punitive Immigration Landscape
Authors: Finno-Velasquez Megan , Dettlaff Alan J.
Published: October 2018

This paper describes specific challenges to family unity and child welfare among children in immigrant families resulting from immigration enforcement. Surges in immigration activity over the past decade have resulted in family economic hardship, psychological trauma to children, and difficulty accessing social services. Children whose parents are detained/deported are at risk of unnecessarily entering the child welfare system, and encounter significant barriers to family reunification. In recent months, the scope of enforcement priorities that previously safeguarded many parents now target a much larger group of immigrants for deportation, increasingly disregarding the needs of children. Immigration raids have terrorized communities across the country, and repercussions are being felt by the child welfare system and social service providers. Within an anti-immigrant political climate, there is a desperate need for social workers to lead initiatives to respond to immigrants’ needs. Strategies include: (1) development of social work expertise in working with immigrants; (2) cross-systems and cross-disciplinary collaborations; (3) leveraging existing resources and supports; (4) documentation/collection of data; and (5) focused advocacy efforts.

Authors: Savi Adriane Cordoni , Tavares Sergio Fernando
Published: October 2018

Com o aumento da população urbana mundial, problemas urbanos passam a ser recorrentes, como por exemplo, as inundações em decorrência da precipitação. Ações que minimizem os impactos ambientais do processo de urbanização passam a ser necessárias, uma dessas ações é a aplicação de telhados verdes, que devido as suas propriedades retém parte da água da chuva e ainda retardam o escoamento dessa água. Alguns estudos demonstram a capacidade de retenção dos telhados verdes, entretanto, sem vincular ao tipo de vegetação. O objetivo da presente pesquisa é verificar a influência da espécie vegetal, utilizada em telhados verdes, na retenção e água de chuva na cidade de Curitiba. Através do estudo em seis espécies vegetais diferentes Bulbine frutescens, Tradescantia zebrina variação Purpusii, Sedum mexicanum, Callisia repens, Arachis Repens e Zoysia tenuifolia. Com esta análise pode-se perceber que existe uma variação de retenção significativa em função da espécie vegetal, sendo que a espécie Bulbine frutescens apresentou o melhor desempenho entre as espécies analisadas.
Envoltórias vegetadas aplicadas em edificações: benefícios e técnicas
Authors: Scherer Minéia Johann , Alves Thales Severo , Redin Janaína
Published: October 2018

O uso da vegetação integrada à arquitetura vem obtendo destaque nos últimos anos, representando uma estratégia para aumento do verde nas cidades, explorando suportes urbanos ainda pouco valorizados como lugares de crescimento de vegetação: é o caso das paredes e das coberturas das edificações. Desta forma, as envoltórias vegetadas podem ser definidas como fechamentos, revestimentos ou elementos construtivos alternativos aos convencionais, que tem a vegetação como componente principal, em conjunto com outras camadas ou suportes para sua fixação ou desenvolvimento. O objetivo deste artigo é realizar um levantamento bibliográfico de informações sobre os benefícios e as principais técnicas de execução de coberturas vivas e jardins verticais. De uma forma geral, tanto as coberturas vivas quanto os jardins verticais podem ser classificados em extensivos ou intensivos, dependendo da forma de implementação e do grau de dificuldade de execução e necessidade de manutenção. Seu uso necessita de planejamento e conhecimento técnico, de forma a ser determinado qual o sistema mais apropriado, quais os cuidados de execução e manutenção, bem como quais espécies são mais adequadas ao clima do local. As principais vantagens para as cidades referem-se à redução na temperatura do ar, com minimização do fenômeno da ilha de calor; umidificação, além de causarem um efeito visual interessante. Na escala da edificação, as envoltórias vegetadas podem contribuir de forma significativa para o conforto térmico e, consequentemente, para a redução no consumo de energia para climatização dos espaços, já que atuam como isolantes térmicos, elementos de sombreamento ou ainda qualificando a ventilação natural por atuarem no resfriamento evaporativo.

URBAN DEVELOPMENT RANGES OF RURAL SETTLEMENTS OF THE STEPPE ZONE OF EUROPEAN RUSSIA
Authors: Petrishchev Vadim P. , Kosykh Polina A.
Published: October 2018

Aim.The steppe zone is not only a unique natural and geographical formation, but also within the framework of European Russia a special region with specific socio-economic and demographic processes. In this article, we consider the issues of town-planning ranking of rural settlements on the basis of comparing the dynamics of their population as the most unique of all socio-economic indicators.Methods.To assess the dynamics of the population, we used the difference in population numbers over a five-year period from 2012 to 2016. When ranking settlements on the dynamics trend, 7 groups were identified, the results were mapped and analyzed.Results.Town-planning ranking has made it possible to identify the most depressive regions that gravitate toward the peripheral territories of the regions, join the borders of neighboring entities, and also form a "frontier" along the Russian-Kazakh border. The most promising areas are located in the south-west of the region under consideration (Krasnodar, Stavropol Krai, south of the Rostov region), where favorable economic and natural-climatic conditions are combined. In addition, promising rural settlements gravitate toward the administrative centers of the regions.Main conclusions.Based on the ranking we have identified trends in the decline of socio-economic indicators from west to east, the negative impact of the Russian-Kazakh border and the periphery of the territory, the growth of prospects towards the Black Sea coast, as well as "urbanization polarization", expressed in the compression of the regional urban space to urbanized centers.
A Three-Phase Rectifier for Wecs With Indirect Current Control
Authors: Silva Carlos E. A. , Jr. Demercil S. Oliveira , Filho Herminio M. de Oliveira , Barreto Luiz H. S. C. , Antunes Fernando L. M.
Published: October 2018

This paper presents a novel Wind Energy Conversion System (WECS) capable of processing the energy from a Permanent Magnetic Synchronous Generator (PMSG) coupled to a three-blade wind turbine and injecting it into the utility power grid. This WECS is composed by two stages: a three-phase rectifier and a single-phase inverter. The ac-dc stage consists of three single-phase bridgeless rectifiers processing the power of each phase of the PMSG separately. The dc-ac stage is composed of a full-bridge inverter with controlled output current. Besides, indirect current control for High Power Factor (HPF) operation is employed, allowing the unification of two important techniques currently available, that are one cycle control (OCC) and selfcontrol (SC). Additionally, a third technique, that comprises the optimum characteristics of both OCC and SC, is proposed and applied to the rectifier stage of the proposed WECS. The proposed WECS and control technique are both validated by experimental results from a 5kW prototype.
ALTERA��ES GENOT�XICAS COMO BIOMARCADORES EM PEIXES DE UMA �REA PROTEGIDA DO SUL DO MARANH�O
Authors: Aguiar Eugenia Miranda
Published: October 2018

Neste estudo, objetivou-se utilizar biomarcadores genot�xicos para avalia��o de impacto ambiental em peixes do Parque Nacional da Chapada das Mesas (PNCM). Exemplares de Leporinus fasciatus (piau) e Hypostomus pusarum (cascudo) foram coletados em duas cachoeiras do PNCM: Cachoeira S�o Rom�o e Prata. As esta��es foram georreferenciadas por GPS (Global Position System) e em cada regi�o foram registradas vari�veis abi�ticas: pH, temperatura, s�lidos totais dissolvidos (TDS), oxig�nio dissolvido (OD) e condutividade. Os dados biom�tricos foram medidos em campo. Para tanto, as l�minas com esfrega�os de sangue foram deixadas em temperatura ambiente por 2 horas para secagem e em seguida fixadas em etanol absoluto por 30 minutos. Depois de secas, as l�minas foram coradas em corante Giemsa. Para a quantifica��o dos eritr�citos, foram utilizadas 2000 c�lulas. Foram identificadas altera��es morfol�gicas nucleares (AMN) nas duas esp�cies amostradas para os dois pontos de coleta. Dentre as AMN encontradas destacam-se: nucl�os binucleados (NB), n�cleos vacuolizados (NV). Os micron�cleos (MN) tamb�m foram encontrados em ambas as esp�cies, por�m, em L. fasciatus a frequ�ncia de MN e AMN foram maiores em rela��o a Hypostomus sp. Provavelmente, o cascudo (H. pusarum) por ser considerado uma esp�cie bent�nica e resistente aos condi��es ambientais apresentou uma frequ�ncia menor de altera��es genot�xicas em rela��o ao L. fasciatus que � uma esp�cie que apresenta um h�bito migrat�rio e sens�vel as vari�veis ambientais. Al�m disso, a frequ�ncia de MN e AMN n�o foram significativas para indicativo de poss�veis impactos ambientais nas duas �reas amostradas. Os dados apresentados mostram que as metodologias baseadas em biomarcadores em esp�cies residentes podem ser utilizadas em futuros programas de biomonitoramento e gest�o do parque.

Published: October 2018

A poliploidia � uma alternativa para melhorar o desempenho zoot�cnico e � amplamente empregada na aquicultura mundial. No Brasil, o emprego de t�cnicas na escala comercial limita-se a uma esp�cie ex�tica de ostra Crassostrea gigas. O objetivo deste estudo foi avaliar a sobreviv�ncia ap�s aplica��o de protocolos de indu��o � triploidia em Anomalocardia brasiliana atrav�s de agentes qu�micos, como Citocalasina B (CB) e 6 - Dimetilaminopurina (6-DMAP), e m�todos f�sicos, por choque t�rmico frio e choque hiposm�tico. A indu��o � triploidia por CB foi realizada a 1 mg. L-1, enquanto que a 6-Dimetilaminopurina a 450 �mol.L-1. As indu��es por choque t�rmico frio foram realizadas a 2, 5 e 7�C, e as indu��es por choque hiposm�tico a 12� de salinidade. As indu��es qu�micas � triploidia apresentaram baixa sobreviv�ncia larval ap�s as primeiras 24 horas, diferentemente dos tratamentos f�sicos, estes obtiveram mais de 90% de sobreviv�ncia, assim como o tratamento controle. Estes resultados demonstram que os tratamentos f�sicos neste per�odo s�o menos agressivos aos ovos e larvas. Por�m novos estudos dever�o ser realizados, a fim de aprimorar os protocolos para obten��o de poliploides para esp�cie.

Published: October 2018

La impresión en tercera dimensión (3D) es el proceso de manufactura controlado por un programa informático de un objeto tridimensional con materiales que se disponen por capas. Sus tres grandes etapas son preprocesamiento, procesamiento y postprocesamiento. En lo que respecta al procesamiento, las distintas técnicas aplicadas abarcan la bioimpresión asistida por láser, la impresión térmica por medio de cartuchos y biotinta, la bioimpresión de escritura directa y la bioimpresión por medio de esferoides. Algunas de las aplicaciones generales de los métodos mencionados son la fabricación de tejido hepático y cardíaco, y la diferenciación de miocitos, ambas útiles para el avance en medicina y en el desarrollo de fármacos. Aun así, existen retos y limitaciones en relación con estos, entre los cuales destacan el desarrollo adecuado de la vasculatura de los órganos y tejidos creados, y el logro del trasplante al paciente de un órgano obtenido por bioimpresión, además de los cuidados de postcirugía, como parte de la inmunovigilancia. Como complemento, se deben considerar una serie de implicaciones bioéticas, de las cuales la implementación del consentimiento informado es relevante en todo paso de la terapia a la que se someta el paciente. Esto implicala creación de leyes y guías que permitan regular el proceso.
Algoritmo semisupervisado de agrupamiento que combina SUBCLU y el agrupamiento basado en restricciones, para la detección de grupos en conjuntos de alta dimensionalidad
Authors: Calvo-Valverde Luis Alexander , Vallejos-Peña Alonso
Published: October 2018

Los datos de alta dimensionalidad plantean un desafío para los algoritmos de agrupamiento tradicionales, ya que las medidas de similitud convencionales utilizadas por estos no son significativas cuando se aplican sobre el espacio completo de datos, por lo que afectan la calidad de los grupos. Ante esto, los algoritmos de agrupamiento de subespacios han sido propuestos como alternativa para encontrar todos los grupos en todos los espacios del conjunto de datos. Al detectar grupos en espacios de menor dimensionalidad, cada grupo detectado puede pertenecer a diferentes subespacios del conjunto de datos original. Consecuentemente, atributos que el usuario considere de interés pueden ser excluidos en algunos o todos los grupos, perdiendo información importante y reduciendo el valor del resultado para los analistas. En este proyecto, se propone un nuevo método que combina el algoritmo SUBCLU y el algoritmo de agrupamiento por restricciones, el cual permite al usuario identificar variables como atributos de interés con base en conocimiento previo del dominio, esto con el objeto de dirigir la detección de grupos hacia espacios que incluyan estos atributos y, por ende, generar grupos más significativos.

Published: October 2018

Ao longo de toda a nossa vida, acumulamos memórias que são compartilhadas por outros indivíduos que fazem ou fizeram parte do mesmo grupo social que nós e podem testemunhar o que vivemos, pois dividiram conosco aquele momento. Em muitos casos, lugares da cidade têm a função de guardar a memória do nosso grupo, pois são nesses locais que vivemos nossas histórias. Mas o que acontece quando esse símbolo da nossa memória é um patrimônio que está abandonado? É com base nessa relação de compartilhamento entre memória, patrimônio e indivíduo que norteamos nosso estudo. O objetivo foi produzir um artigo que retome as memórias de um grupo de ex-ferroviários que trabalharam na Estação Ferroviária Nova de Campina Grande-PB, com o intuito de que elas nos ajudem a despertar o interesse por esse espaço, hoje abandonado, e promova sua valorização.
Pilar: um núcleo habitacional para a indústria mineradora na caatinga baiana
Authors: Soriano Ana Gabriela Wanderley
Published: October 2018

O impulso econômico dos anos de 1970 e o despertar do planejamento urbano patrocinaram a criação de núcleos habitacionais no cenário da mineração, provocando o deslocamento de capital e mão-de-obra pelo Brasil. Tais assentamentos nasceram sob a tutela das empresas mineradoras e, em alguns casos, amadureceram e tornaram-se independentes. Se por um lado a exploração dos minérios foi o propulsor do surgimento de núcleos urbanos de apoio à mineração pelo interior do país, por outro lado o seu fracasso ou fim selou e traçou o destino de diversas localidades. Implantado no Vale do Curaçá, na caatinga baiana, Pilar, hoje distrito de Jaguarari, foi projetado para abrigar os trabalhadores envolvidos na extração do cobre pela Mineração Caraíba S/A. Para o desenvolvimento do projeto do Núcleo Residencial do Pilar, no final da década de 1970, foi contratada a equipe do arquiteto Joaquim Guedes. O objetivo, portanto, do presente trabalho é discorrer a respeito da criação e da história de Pilar, analisando a sua conformação arquitetônica e urbanística, como um núcleo urbano surgido como apoio às atividades de exploração de cobre e a importância de preservação deste patrimônio industrial.

Authors: Copuroglu Elif , Sagiroglu Gonul , Bilgili Beliz , Hekimogl Sevtap
Published: October 2018

Purpose: Transurethral resections (TUR) are commonly performed for elderly population who have multiple comorbidities which can cause intraoperative and postoperative complications. The type of anesthesia has an impact on patient outcome. The aim of the study is to compare the effectiveness of epidural and spinal anesthesia techniques for TUR. Methods: A total of 158 elective TUR cases were evaluated. The patients were randomized into 2 groups: Epidural anesthesia was applied to Group I (n=82) and spinal anesthesia was applied to Group II (n=76). Both groups were compared for intraoperative hemodynamic parameters (mean arterial pressure, heart rate, peripheral oxygen saturations), total duration of hospital stay, perioperative complications, and satisfaction of the patients and surgeons. Results: The patients in the spinal anesthesia group experienced more frequent intraoperative hypotensive episodes during TUR (n=2 vs. n=10; p=0.026) and had lower mean arterial pressure values for the first 30 minutes of anesthesia compared to epidural anesthesia group. The postoperative duration of bed stay was longer in the spinal anesthesia group (402.96±49.61 min) than the epidural anesthesia group (205.91±28.27 min) (p<0.001). The patient satisfaction score was significantly higher in the epidural anesthesia group (2.54±0.63) than the spinal anesthesia group (2.23±1.22) (p=0.04) where as the surgeon satisfaction score were similar in both groups. Conclusion: Epidural anesthesia can be considered as an effective and safe technique for ambulatory interventions especially for elderly patients providing perioperative hemodynamic stability and postoperative early mobilization.

Published: October 2018

This work is located in a growing sector within the field of renewable energies, wave energy converters (WECs). Specifically, it focuses on one of the point absorbers wave (PAWs) of the hybrid platform W2POWER. With the aim of maximising the mechanical power extracted from the waves by these WECs and reduce their mechanical fatigue, the design of five different model predictive controllers (MPCs) with hard and soft constraints has been carried out. As contribution of this paper, two of the MPCs have been designed with the addition of an embedded integrator. In order to validate the MPCs, an exhaustive study on performance and robustness is realized through simulations carried out in which uncertainties in the WEC dynamics are considered. Furthermore, looking for realistic in these simulations, an identification methodology for PAWs is proposed and validated by means of real time series of a scale prototype.

Various environmental challenges, related to oil palm commodity has became a major environmental challenge to oil palm production. The aim and objective of this study is to analyze the actual water footprint of oil palm based on root water uptake under varying crop age and soil type. The research was conducted in Pundu Village, Central Kalimantan. The methodology adopted in carrying out this study consists of various stages which includes observing soil moisture, rainfall, and water table, ETo, root water uptake and oil palm water footprint. The highest rate of water consumption was the 13 years oil palm on spodosol soil type with an average daily rate of 3.73 mm/day. The lowest evapotranspiration was represented by the 7th year oil palm on spodosol with an average rate of 3.07 mm/day. The total water footprint value obtained was between 0.56 – 1.14 m3/kg for a variety of plants with various age and soil types. It can be deduced that the water footprint value of oil palm vary for different crop age and soil types on temporal scale. The study also presented that the source of green water from the first root zone of oil palm deliver the highest contribution for oil palm root water uptake.

Recently, there have been revolutions in the development of both gene therapy and genome surgical treatments for inherited diseases. Much of this progress has been centered around hereditary retinal dystrophies, because the eye is an immune-privileged and anatomically ideal target. Gene therapy treatments, already demonstrated to be safe and efficacious in numerous clinical trials, are benefitting from the development of new viral vectors, such as dual and triple AAVs. CRISPR/Ca9, which revolutionized the field of gene editing, is being adapted into more precise “high fidelity” and catalytically dead variants. New CRISPR endonucleases, such as CjCas9 and Cas12a, are generating excitement in the field as well. Stem cell therapy has emerged as a promising alternative, allowing human embryo derived stem cells and induced pluripotent stem cells to be edited precisely in vitro and then reintroduced into the body. This article highlights recent progress made in gene therapy and genome surgery for retinal disorders, and it provides an update on precision medicine FDA treatment trials.

OBJECTIVE: Musicians are often compared to athletes because of the physical exertion required to play music. The aim of this study was to explore the physical activity level of music students and to study its relationship with musculoskeletal complaints. A second goal was to assess
associations between physical activity and pain, quality of life, and disability. METHODS: This cross-sectional study among third- and fourth-year music students used an electronic survey including measures for physical activity (SQUASH—Short Questionnaire to Assess Health-enhancing
physical activity), musculoskeletal complaints (DMQ—Dutch Musculoskeletal Questionnaire), disability (DASH—Disability Arm, Shoulder, Hand questionnaire) and quality of life (Short Form-12). Students were classified as compliers or non-compliers with moderate- and vigorous-intensity
physical activity recommendations. Statistical analysis was done using (non)parametric tests (t-test, Pearson chi-square test, Mann-Whitney U-test) and correlational testing. RESULTS: Participants were 132 students, 63.6% female, with a median age of 23 yrs (range 21.3–25.0). 67% reported
musculoskeletal complaints in the past 7 days. Their median physical activity level was 6,390 MET-min/wk, and 62% and 10% of the students accomplished recommendations for moderate-intensity and vigorous-intensity physical activity levels, respectively. No significant differences were found
in prevalence of musculoskeletal complaints between students who met moderate- or vigorous-intensity physical activity recommendations and students who did not. Physical activity level was not associated with musculoskeletal complaints (r=0.12, p=0.26). Higher pain intensity was associated
with a lower quality of life (r=–0.53 p<0.01) and higher disability (r=0.43, p<0.01). CONCLUSIONS: Music students are mainly involved in light- to moderate-intensity physical activities and rarely in vigorous-intensity activities. No correlation was found between physical activity
level in the past months and musculoskeletal complaints in music students.

In tertiary education, generic professional skills should be developed along with discipline-specific knowledge and skills. Team-Based Learning (TBL), an active learning strategy, creates deep learning and enhanced student engagement; however, its effects on the development of generic learning outcomes are unknown. The aim of this study was to evaluate postgraduate specialty nursing students’ perspectives of how TBL impacts the acquisition of skills defined by the university’s eight Graduate Learning Outcomes (GLOs). A descriptive exploratory design was used in this study. Postgraduate nursing students in 2016-2017 at one university were invited to participate. Data were collected via demographic survey, a ranking tool, and written reflections. Data were analysed using descriptive statistics and content analysis. The response rate was 97.2 per cent (172/177). Participants were mostly females (n=152, 88.4%) aged 25–34 years (n=115, 66.9%). Student (n=156) rankings showed TBL contributed to the acquisition of critical thinking (n=90, 57.7%) and problem solving skills (n=56, 35.9%) the most. Students (n=144) made 2719 comments regarding how TBL led to the acquisition of GLOs in written reflections. Almost 98 per cent (n=2657) of all reflective comments were positive. All students mentioned at least one GLO positively due to TBL. Most positive reflections related to self-management (n=520, 19.6%) and communication (n=434, 16.3%).Postgraduate specialty nursing students perceived TBL classes contributed to the acquisition of their university’s GLOs, particularly critical thinking, problem solving, and self-management skills. The active learning strategy of TBL facilitates learning and engagement, and the attainment of essential professional attributes which are highly valued by employers.
The Effect of Resin Coated Proppant and Proppant Production on Convergent Flow Skin in Horizontal Wells with Transverse Fractures
Authors: Shaoul J. R. , Park J.. , Langford M..
Published: October 2018

In the last decade, many gas reservoirs with permeabilities from 0.1 to 10 mD have been developed with horizontal wells with transverse fractures. The potential negativeimpact of convergent flow in the fracture seems to have been forgotten. The widespread use of resin coated proppant (RCP) in offshore wells appears to make this problem worse. Using both case studies and reservoir simulations, we examine why RCP could make the problem of convergent flow worse compared to uncoated proppant.

A number of North Sea horizontal and deviated multi-frac gas wells that used RCP and had a significant mechanical skin are presented. Pressure buildup data confirms the presence of a near-wellbore pressure drop in the fracture. Reservoir simulation with a fine grid reproduces the observed pressure drop, due to convergent flow, using realistic proppant pack permeabilities with gel damage.

The effect of proppant production on the convergent flow skin is shown using production data before and after discrete proppant production events, demonstrating how proppant production has a beneficial effect on removing convergent flow skin. We also compare the performance of a new horizontal multi-frac well to the original discovery well in the same location, where a vertical well was fracture stimulated with uncoated proppant, and had comparable productivity.

If there is a large convergent flow skin in a fracture with uncoated proppant, this usually leads to some proppant production, which could create "infinite conductivity" channels at the perforations. This removes the convergent flow pressure drop. If RCP is used to prevent proppant flowback, such channels cannot form easily and convergent flow acts as a downhole "choke" on production. This "choke" can produce a significant positive skin. In unfavorable cases, a horizontal multi-frac well with 3 or 4 transverse fractures will produce the same as a fully perforated vertical well with a single fracture.

Based on a number of real-world incidents of proppant production during the post-fracture cleanup, we show strong evidence that a small amount of proppant production can result in an increase in well PI and decrease in apparent fracture skin. Convergent flow is the most likely mechanism to explain this. This paper highlights the potential reduction in well productivity due to using resin coated proppant for fracturing in gas wells (0.1 to 10 mD) with limited inflow area (transverse or oblique fractures) where convergent flow pressure loss is significant. We show the potential positive effect of small amounts of proppant production in such cases, forming infinite conductivity channels and removing the convergent flow skin.

The Tuba carbonate reservoir in the Sabriyah field, North Kuwait was deposited above the Wara shale and overlaid by the Ahmadi shale. It is divided into three stratigraphic units: upper, middle, and lower. This formation was considered to have limited opportunity for production enhancement. However, improved reservoir characterization along with developed pinpoint fracture acidizing technologies have provided new opportunities to improve recovery and increase pay zone productivity.

Pinpoint fracture acidizing technology, using drillpipe with a bottomhole pinpoint tool assembly, has helped to effectively stimulate pay intervals individually using acid fracturing treatments. This resulted in achieving multiple stimulation treatments in a single trip, where each treatment stage was tailored for the specific interval being treated. Moreover, this pinpoint technique increased the number of treated stages per well compared to conventional multistage fracture acidizing, which led to greater efficiency and greater production.

This technology has been successfully used for multiple zones in complex reservoirs to improve production and reservoir recovery. It provided an effective method to help boost production and injection from tight zones in openhole horizontal completions and completions where zonal isolation could be compromised. This treatment process helped optimize hydrajetting and acid fracturing technologies along with treatment design for individually placed fractures by using the dynamic fluid movement to divert fluid flow into a specific treatment point in the formation. This service required a different approach to treatment design by controlling and evaluating two primary fluid injection paths, which necessitates two separate pumping systems. However, a proper well candidate is important to the success of any stimulation treatment.

This paper discusses methodology and treatments applied on a recent well in the Tuba carbonate reservoir in a horizontal openhole completion. The technical approach taken during the design of the treatments is presented in detail, as well as the operational challenges encountered during the multistage fracture acidizing treatments. This stimulation technique was implemented successfully to perform a seven-stage acid treatment in a single lateral. The overall success of this project proves that there is a technical alternative to the traditional fracture acidizing methodology for wells of this type.
