Confronting Scenarios in Tsitsi Dangarembgaâ€™s She No Longer Weeps
Authors: Vhutuza Ephraim , Mucheke Noreen
Published: May 2018

The paper explores the role of the play titled She No Longer Weeps by Tsitsi Dangarembga in interrogating the prevailing status quo of, what the paper refers to as, the â€œscenarios.â€ In this paper, we focus on how the play facilitates and shapes social change in independent Zimbabwe in the 1980s. Whereas it is undeniable that social change occurs at various levels in society, we concentrate on the change that occurs in the domestic space of the family and/or home, and specifically in gender power relations, as this is the playâ€™s main focus. The paper argues that She No Longer Weeps represents a discussion about ways in which characters attempt to change and/or resist the transformation of the Zimbabwean society. Relying on textual analysis and the historical and material conditions that informed the dramatistâ€™s vision, the paper concludes that gender power relations, as in Zimbabwe in the 1980s, need to be rethought and transformed, but we also question the dramatistâ€™s wholesale acceptance of radical feminism. We conclude by rejecting radical and/or Western feminism in favour of Africana womanism as the latter encourages co-existence and understanding between men and women within the family institution.
The Prophetic Voice of the Church in a Democratic South Africa â€“ A Theological Reflection
Authors: Mudimeli Lufuluvhi Maria
Published: May 2018

This article is a reflection on the role and contribution of the church in a democratic South Africa. The involvement of the church in the struggle against apartheid is revisited briefly. The church has played a pivotal and prominent role in bringing about democracy by being a prophetic voice that could not be silenced even in the face of death. It is in this time of democracy when real transformation is needed to take its course in a realistic way, where the presence of the church has probably been latent and where it has assumed an observer status. A look is taken at the dilemmas facing the church. The church should not be bound and taken captive by any form of loyalty to any political organisation at the expense of the poor and the voiceless. A need for cooperation and partnership between the church and the state is crucial at this time. This paper strives to address the role of the church as a prophetic voice in a democratic South Africa. Radical economic transformation, inequality, corruption, and moral decadenceâ€”all these challenges hold the potential to thwart our young democracy and its ideals. Black liberation theology concepts are employed to explore how the church can become prophetically relevant in democracy. Suggestions are made about how the church and the state can best form partnerships. In avoiding taking only a critical stance, the church could fulfil its mandate â€œin season and out of seasonâ€ and continue to be a prophetic voice on behalf of ordinary South Africans.

MATEMÁTICA EM CONTEXTO E APLICAÇÕES: CONEXÕES ENTRE ARTE E MATEMÁTICA
Authors: Sabino Adílio Jorge , Vizolli Idemar
Published: May 2018

A Matemática e a Arte estão diretamente ligadas à vivência humana. O presente trabalho tem como objetivo verificar possíveis conexões entre Arte e Matemática presentes em livros didáticos do Ensino Médio utilizados por professores do Instituto Federal do Pará – Campus Conceição do Araguaia. O estudo foi organizado em duas etapas: na primeira analisa-se imbricações e rupturas nas relações históricas entre Arte e Matemática; na segunda estuda-se o modo como é abordada a Arte nos livros didáticos de Matemática. A metodologia utilizada se consistiu de um estudo bibliográfico, de abordagem qualitativa, em que resenha-se aspectos de Artes e Matemática. Os resultados indicam um distanciamento da relação entre essas duas áreas de conhecimento, ainda que, em diversos momentos da história, elas se inter-relacionavam. São raras e elementares as abordagens entre Arte e Matemática apresentadas nos livros didáticos analisados e tampouco exploram possibilidades de aprendizagens de conceitos na e entre as áreas de conhecimento.

Published: May 2018

From December 2013 to March 2016, West Africa experienced the largest Ebola virus (EBOV) outbreak to date, leading to a European-wide activation of laboratory preparedness and response. At the end of the outbreak, laboratories associated with the two European preparedness networks of expert laboratories EMERGE JA and EVD-LabNet were invited to participate in an assessment of the response of European laboratories to the EBOV outbreak, to identify learning points and training needs to strengthen future outbreak responses. Response aspects assessed included diagnostics, biorisk management and quality assurance. The overall coverage of EBOV diagnostics in the European Union/European Economic Area (EU/EEA) was found to be adequate although some points for quality improvement were identified. These included the need for relevant International Organization for Standardization (ISO) accreditation, the provision of EBOV external quality assessments (EQA) in periods where there is no emergency, facilitating access to controls and knowledge, biorisk management without compromising biosafety and a rapid public health response, and the need for both sustained and contingency funding for preparedness and response activities.

Estudio de cilias respiratorias y requerimientos básicos de la muestra para microscopía electrónica de transmisión
Authors: Sua Luz Fernanda
Published: May 2018

La discinesia ciliar primaria (DCP) es una enfermedad hereditaria, principalmente autosómica recesiva, caracterizada por disfunción de las células ciliadas presentes en los tejidos respiratorio y gonadal, entre otros. La prevalencia aproximada de síndrome de Kartagener, que basa el diagnóstico en el estudio ultraestructural ciliar, es de 1/10 000 nacidos vivos (1, 2). La DCP incluye un grupo de enfermedades en la que las cilias respiratorias son inmóviles (síndrome de inmovilidad ciliar), el movimiento ciliar es discinético e ineficaz (DCP) o no hay cilias (aplasia ciliar), este último es extremadamente infrecuente (1, 3, 4). En 1976, Afzelius describió como origen del trastorno, la ausencia de brazos de dineína en los microtúbulos de las cilias bronquiales y de los flagelos de los espermatozoides (5). La célula ciliada normal se compone por unas 250 proteínas organizadas en torno a un axonema o conjunto de microtúbulos, que se extiende desde el citoplasma hasta el extremo final de la cilia. La cilia normal consiste en un par central de microtúbulos rodeados por una vaina y otros 9 dobletes externos, formando la organización característica «9+2». Los complejos de dineína se asocian con los dobletes periféricos; los puentes de nexina sostienen los dobletes periféricos entre sí; y los rayos radiales (radial spoke) unen el par central con los periféricos.

Work and Consumption in Digital Capitalism: From Commodity Abstraction to 'Eidetisation'
Authors: Cava Xavi
Published: May 2018

The digital sphere can be studied as one of the most mature materialisations of the process of abstraction that accompanies capitalism. It is also a framework where subjectivity internalises the abstract form of commodities even further. In this sense, the Internet is the home of an abstract nature that is linked to a particular reification process that characterises post-Fordist production and consumption. This process can be named “eidetisation”. My basic assumption is that the process of reification is being intensified with the digitalisation of the capitalist system. I will begin discussing the concept of reification as a specific form of alienation, stressing that the reification of society changes and intensifies in as much as capitalist production and consumption evolve. Then I will consider the process of abstraction as one of the main elements of reification. Finally, I will try to identify some distinctive traits within the process of “eidetisation”.
Rice development in the context of climate change in Vietnam
Authors:   Vietnam Academy of Agriculture Sciences, Nguyen Van Bo
Published: May 2018

Rice is the most important crop of Vietnam with a harvested area of 7,835 ha, production of 45.2 million tons of paddies, and export volume of 6,997 thousand tons of milled rice for an export value of USD 2,852 million in 2015. However, if purely considering its economic aspects, rice contributes only 5.45% of national GDP1 and rice farmer’s net income is only USD 419/ha compared to USD 1,128/ha earnings of Thailand farmers. Moreover, it is projected that up to 16.8% of the Red River Delta and 38.9% of the Mekong River Delta will be submerged after sea level rises by 100 cm. If this happens, a reduction in rice production would be more than 30-35%, based on the 2016 climate change scenarios. Therefore, it is necessary to thoughtfully consider rice production and rice export through different perspectives including economic, societal and environmental with a focus on ensuring food security and social stability.

Abstract - Permissions setting on a computer is necessary. This is an effort that is not easy to change the system configuration or settings changed by the user. With a network of computers, of course, permissions setting do not need to be done one by one manually. Because in a computer network course there are many collection of computers connected together. Permissions setting so that the system can use the client-server applications that access restrictions can be done effectively. As the implementation of client-server applications can be created using Visual Basic 6.0. This language has been able to access the socket on the Windows operating system, named Winsock API that supports TCP / IP. This protocol is widely used because of the reliability of client-server application programming. The application is divided into two main applications, namely the client and server program name with the name of the Receiver Sender program. Receiver function receives instructions restriction of access rights Sender and send reports to the Sender process execution. While Sender function to send instructions restrictions permissions via the Registry to the Receiver. And after the test, the application can block important features available in the Windows operating system. So it is expected that these applications can help in permissions setting on a computer network.

Abstrak - Pengaturan hak akses di suatu komputer sangat diperlukan. Hal ini merupakan salah satu upaya agar konfigurasi sistem tidak mudah dirubah atau diganti pengaturannya oleh pengguna. Dengan adanya jaringan komputer, tentunya pengaturan hak akses tidak perlu dilakukan satu-satu secara manual. Karena dalam suatu jaringan komputer pastinya terdapat banyak kumpulan komputer yang saling terhubung. Sehingga pengaturan hak akses bisa menggunakan sistem aplikasi client-server agar pembatasan hak akses bisa dilakukan dengan efektif. Sebagai implementasi aplikasi client-server dapat dibuat dengan menggunakan bahasa pemrograman Visual Basic 6.0. Bahasa ini sudah bisa mengakses socket pada sistem operasi Windows yang diberi nama Winsock API yang sudah mendukung protokol TCP/IP. Protokol ini banyak dipakai karena kehandalannya dalam pemrograman aplikasi client-server. Aplikasi ini terbagi menjadi dua aplikasi utama, yaitu client dengan nama program Receiver dan Server dengan nama program Sender. Receiver berfungsi menerima instruksi pembatasan hak akses dari Sender dan mengirimkan laporan hasil proses eksekusinya ke Sender. Sedangkan Sender berfungsi untuk mengirim instruksi pembatasan hak akses melalui Registry ke Receiver. Dan setelah di uji, aplikasi ini dapat memblok fitur-fitur penting yang ada di sistem operasi Windows. Sehingga diharapkan dengan adanya aplikasi ini dapat membantu dalam pengaturan hak akses di suatu jaringan komputer.

Each time the new innovation is made, it presents some new difficulties for the insurance of information and data. To secure the information and data in association is imperative on the grounds that association nowadays inside and remotely joined with systems of IT frameworks. IT structures are inclined to dissatisfaction and security infringement because of slips and vulnerabilities. These slips and vulnerabilities can be brought on by different variables, for example, quickly creating headway, human slip, poor key particulars, poor movement schedules or censuring the threat. Likewise, framework changes, new deserts and new strikes are a huge piece of the time displayed, which helpers augmented vulnerabilities, disappointments and security infringement all through the IT structure life cycle. The business went to the confirmation that it is essentially difficult to ensure a slip free, risk free and secure IT structure in perspective of the disfigurement of the disavowing security parts, human pass or oversight, and part or supplies frustration. Totally secure IT frameworks don't exist; just those in which the holders may have changing degrees of certainty that security needs of a framework are fulfilled do. The key viewpoints identified with security of data outlining are examined in this paper. From the start, the paper recommends pertinent legitimate structure and their duties including open association obligation, and afterward it returns to present and future time, system limits, structure security in business division. At long last, two key inadequacy markers system force and structure reliance – are discovered and tantamount with EU nations. Thusly I indicated reason viewpoints and figures of security of data structures it additionally relates to the reason of estimation of transient dangers of security of frameworks for that I begin my proposal with one of the fundamental class of data security which is Cyber security.

En s'attardant plus à la construction des salles de cinéma qu'aux questions de distribution, cette étude dépasse les simples paramétres du control qu'a toujours exercé Hollywood sur le cinéma canadien pour offrir un cadre de recherche permettant de comprendre la spécificité locale de l’enthousiasme des foules pour te cinéma.
Effets de l’hyperoxie sur le pronostic après un arrêt cardiaque
Authors: Llitjos J.-F. , Cariou A.
Published: May 2018

Un effet toxique de l’oxygène est aujourd’hui suspecté chez les patients pris en charge pour un arrêt cardiaque. Indispensable pendant la réanimation cardiopulmonaire (RCP), l’administration d’oxygène en quantité trop importante pourrait cependant majorer les lésions provoquées par le syndrome d’ischémie–reperfusion globale. Expérimentalement, l’exposition des animaux à une hyperoxie pendant et après la RCP augmente les phénomènes en rapport avec le stress oxydatif et semble responsable d’une aggravation du pronostic, au travers notamment des lésions cérébrales. Cependant, la transposition clinique de ces observations est incertaine : chez l’homme, les résultats de certaines études rétrospectives suggèrent un effet délétère de l’hyperoxie post-arrêt cardiaque, mais ces études sont entachées de nombreux biais méthodologiques, et leurs conclusions ont été en partie remises en question dans des études ultérieures. En attendant les résultats des investigations cliniques en cours, les recommandations internationales actuelles préconisent de titrer dès que possible l’oxygène administré pendant et après la RCP pour maintenir une saturation de l’oxygène entre 94 et 98 %.
Place de l’assistance circulatoire extracorporelle dans l’arrêt cardiaque réfractaire

Le bénéfice d’une réanimation cardiopulmonaire (RCP) extracorporelle en comparaison d’une réanimation conventionnelle sur la survie et le pronostic neurologique à long terme des patients victimes d’un arrêt cardiaque réfractaire reste encore incertain. Il pourrait être très différent selon que la RCP soit considérée dans les arrêts cardiaques extrahospitaliers ou intrahospitaliers, d’origine cardiaque ou pas, en contexte toxicologique ou d’hypothermie. L’objectif de cet article est une mise au point sur l’apport de l’assistance circulatoire extracorporelle dans la prise en charge des arrêts cardiaques réfractaires à partir des recherches cliniques les plus récentes. Ainsi, l’apport d’une RCP extracorporelle dans les arrêts cardiaques réfractaires extrahospitaliers d’origine cardiaque est probablement limité, même au sein de populations hautement sélectionnées. En revanche, son intérêt est probablement plus important dans les arrêts cardiaques réfractaires intrahospitaliers d’origine cardiaque sous réserve d’une bonne sélection des patients. Enfin, si des résultats encourageants ont été rapportés dans les cas d’arrêt cardiaque réfractaire de cause toxique ; en revanche, ils sont plus contrastés concernant les arrêts cardiaques réfractaires associés à une hypothermie profonde suite à une exposition accidentelle au froid, à une noyade ou une avalanche. Des recherches bien conduites sont encore nécessaires pour préciser les contextes et les indications pour lesquels les patients seraient en droit d’attendre un bénéfice médical d’une RCP extracorporelle.

Published: May 2018

Renal cell carcinoma (RCC) is the commonest primary tumor of the kidney which may invade through the renal vein into the inferior vena cava (IVC), and then it can extend intraluminally with subsequent tumor-thrombus formation. Here we report a case involving excision of a primary RCC with tumor-thrombus involving IVC up to right atrium with the use of extracorporeal circulation. Single stage surgical procedure was performed in collaboration with a urological team aiming complete resection of primary tumor, para-aortic lymphadenectomy and removal of IVC thrombus extending to right atrium with the help of cardiopulmonary bypass. After arresting heart, RA was opened and the mass was removed through RA from IVC and hepatic vein level. Abdominal IVC was opened and the entire residual mass was removed from below also small amount of thrombus removed from left renal vein. Postoperative venous doppler showed no residual thrombus in venous system. Histopathology report confirmed papillary renal cell carcinoma. The patient was discharged from hospital in the 12th post-operative day without any complication.J Bangladesh Coll Phys Surg 2018; 36(2): 77-79

A Reliability Assessment of the Hydrostatic Test of Pipeline with 0.8 Design Factor in the West–East China Natural Gas Pipeline III
Authors: Wen Kai , He Lei , Yu Weichao , Gong Jing
Published: May 2018

The use of 0.8 design factor in Chinese pipeline industry is a breakthrough with the success of the test pipe section in the west–east China gas pipeline III. For such a design factor, the traditional P-V (Pressure-Volume) curve based pressure test control cannot describe the details of the process, and the 0/1 type failure is not an efficient index to show the safety level of the pipeline. In this paper, a reliability based assessment method is proposed to monitor the real-time failure probability of the pipeline during the hydrostatic test process. The reliability index can be used as the degree of risk. Following the actual hydrostatic testing of a test pipe section with 0.8 design factor in the west–east China gas pipeline III, reliability analysis was performed using Monte Carlo technique. The basic values of input parameters of the limit state equations are based on the data collected from either the tested section or the recommended value in the codes. The analysis of limit states, i.e., the yielding deformation and the excessive plastic deformation of pipeline, proceeded based on these distributions. Finally, it is found that the gradually increased water pressure makes the failure probability increase accordingly. A reliability assessment method was proposed and illustrated with the practical pressure test process.

Published: May 2018

In the process industry, measurement systems are required for process development and optimization, as well as for monitoring and control. The processes often involve multiphase mixtures or flows that can be analyzed using tomography systems, which visualize the spatial material distribution within a certain measurement domain, e.g., a process pipe. In recent years, we studied the applicability of soft-field electromagnetic tomography methods for multiphase flow imaging, focusing on concepts for high-speed data acquisition and image reconstruction. Different non-intrusive electrical impedance and microwave tomography systems were developed at our institute, which are sensitive to the local contrasts of the electrical properties of the materials. These systems offer a very high measurement and image reconstruction rate of up to 1000 frames per second in conjunction with a dynamic range of up to 120 dB. This paper provides an overview of the underlying concepts and recent improvements in terms of sensor design, data acquisition and signal processing. We introduce a generalized description for modeling the electromagnetic behavior of the different sensors based on the finite element method (FEM) and for the reconstruction of the electrical property distribution using the Gauss–Newton method and Newton’s one-step error reconstructor (NOSER) algorithm. Finally, we exemplify the applicability of the systems for different measurement scenarios. They are suitable for the analysis of rapidly-changing inhomogeneous scenarios, where a relatively low spatial resolution is sufficient.
Recurrent Neural Network for Partial Discharge Diagnosis in Gas-Insulated Switchgear

Published: May 2018

The analysis of partial discharge (PD) signals has been identified as a standard diagnostic tool for monitoring the condition of different electrical apparatuses. This study proposes an approach to detecting PD patterns in gas-insulated switchgear (GIS) using a long short-term memory (LSTM) recurrent neural network (RNN). The proposed method uses phase-resolved PD (PRPD) signals as input, extracts low-level features, and finally, classifies faults in GIS. In the proposed method, LSTM networks can learn temporal dependencies directly from PRPD signals. Most existing models use support vector machines (SVMs) and mainly focus on improving feature representation and extraction manually to analyze PRPD signals. However, the proposed model captures important temporal features with the help of its low-level feature extraction capability from raw inputs. It outperforms conventional SVMs and achieves 96.74% classification accuracy for PRPDs in GIS.

The heat pump water heater (HPWH), as a portion of the eco-friendly technologies using renewable energy, has been applied for years in developed countries. Air-source heat pump water heaters and solar-assisted heat pump water heaters have been widely applied and have become more and more popular because of their comparatively higher energy efficiency and environmental protection. Besides use of the above resources, the heat pump water heater system can also adequately utilize an available water source. In order to study the thermal performance of the water-source heat pump water heater (WSHPWH) system, an experimental prototype using the cyclic heating mode was established. The heating performance of the water-source heat pump water heater system, which was affected by the difference between evaporator water fluxes, was investigated. The water temperature unfavorably exceeded 55 °C when the experimental prototype was used for heating; otherwise, the compressor discharge pressure was close to the maximum discharge temperature, which resulted in system instability. The evaporator water flux allowed this system to function satisfactorily. It is necessary to reduce the exergy loss of the condenser to improve the energy utilization of the system.
Determining Time-Varying Drivers of Spot Oil Price in a Dynamic Model Averaging Framework
Authors: Drachal Krzysztof
Published: May 2018

This article presents results from modelling spot oil prices by Dynamic Model Averaging (DMA). First, based on a literature review and availability of data, the following oil price drivers have been selected: stock prices indices, stock prices volatility index, exchange rates, global economic activity, interest rates, supply and demand indicators and inventories level. Next, they have been included as explanatory variables in various DMA models with different initial parameters. Monthly data between January 1986 and December 2015 has been analyzed. Several variations of DMA models have been constructed, because DMA requires the initial setting of certain parameters. Interestingly, DMA has occurred to be robust to setting different values to these parameters. It has also occurred that the quality of prediction is the highest for the model with the drivers solely connected with the stock markets behavior. Drivers connected with macroeconomic fundamental indicators have not been found so important. This observation can serve as an argument favoring the hypothesis of the increasing financialization of the oil market, at least in the short-term period. The predictions from other, slightly different modelling variations based on DMA methodology, have happened to be consistent with each other in general. Many constructed models have outperformed alternative forecasting methods. It has also been found that normalization of the initial data, although not necessary for DMA from the theoretical point of view, significantly improves the quality of prediction.
