Authors: Sharma Prakash , Gyawali Merina , Gurung Sangita Devi
Published: March 2018

Introduction: Umbilical artery Doppler is a noninvasive tool in the evaluation of the foetal and uteroplacental circulation. The aim of this study was to evaluate the role of umbilical artery Doppler in pregnancy induced hypertension (PIH) ladies with clinical suspicion of intrauterine growth restriction (IUGR) and to predict the fetal outcome.Methods: A total of 44 singleton pregnancies beyond 34 weeks of pregnancy complicated with pregnancy induced hypertension and clinical suspicion of intrauterine growth restriction were evaluated using ultrasonography and Doppler. Six pregnant ladies were excluded from the study. The umbilical artery systolic/diastolic (S/D) ratio was calculated from a free loop of cord midway between the placenta and insertion of cord. All the pregnant ladies were followed up till delivery. Birth weight, adverse foetal outcome were recorded. Babies were divided into two groups, small for gestational age (SGA) and appropriate for gestational age (AGA) based on Lubchenco growth chart. SGA was considered as IUGR.Results: Abnormal S/D in umbilical artery was seen in 26 pregnant ladies, out of which 22 had an abnormal resistive index (RI). Umbilical artery S/D ratio had a sensitivity of 66.7% and specificity of 28.57%, in diagnosing IUGR. Umbilical artery RI had a sensitivity of 50% and specificity of 28.6% in diagnosing IUGR. Similarly, S/D ratio of the umbilical artery had a sensitivity of 100 %, specificity of 46.2%, in diagnosing adverse foetal outcome. RI was 100% sensitive in diagnosing foetal outcome.Conclusion: Umbilical artery Doppler plays an important role in PIH in diagnosing IUGR and predicting a foetal outcome.

The results showed that the tensile properties of the composites were improved with the increase of extrusion ratio only up to 12 : 1 for the extrusion temperatures of 450 and 500 °C, but continued to improve at extrusion temperature of 550 °C due to the considerable reduction in porosity and appropriate alignment of reinforcing phase. Furthermore, the increased extrusion temperature resulted in improvement of elongation and tensile strength at the expense of yield strength. It was found that the extrusion treatment under the conditions of larger sized particles, lower temperature and higher ratio provided more pronounced breakage of SiC particles which could be beneficial if the broken pieces of SiC were totally embedded in the matrix.
(Not) Becoming the Norm

Women have long served in the Israel Defense Forces, notwithstanding
strong opposition by the Chief Rabbinate. In the twenty-first
century, approximately 25 percent of female graduates of Israel’s religious
high school system enlist, despite social disapproval. Israel’s Orthodox
community has largely ignored the issue in the past. Recently, however,
rabbis and public figures within the religious community have acknowledged
the reality of women’s conscription and have shown some willingness
to address it. Although religious female soldiers are still atypical,
they are no longer viewed as the anathema they once were. This article
presents a possible model for this legitimation as a social process. It then
describes the relationship between religious women, military service, and
conscription in Israel, concluding with a suggestion about broader contexts
within which this change can be viewed.

Determining the optimum placement of braces in steel frames has always been one of the most challenging issues in structural engineering. In this paper, the size and placement of the X-braces in planar frame structures is determined in a way that the total weight of the braced frames becomes minimum, while satisfying the design requirements and constraints. Variables of the optimization contain the cross sections for beams, columns, and X-braces as well as the placement of these braces in the frames. Attempt has also been made to consider all the constraints of an actual design problem. One of the other objectives of this study is to investigate the effect of including or excluding some of the constraints affecting the optimization of the planar frame design. For this purpose, the Colliding Bodies Optimization (CBO) and CBO-MDM algorithms have been utilized. Modified Dolphin Monitoring (MDM) operator is recently developed for improving the performance of the metaheuristic algorithms. Here, this operator is utilized to enhance the performance of the CBO algorithm to optimize the weight of the frames. For additional comparison of the results, the particle swarm optimization (PSO) algorithm and imperialist competitive algorithm (ICA) are used.

Petroleum system of Srikail gas field using sequence stratigraphy
Authors: Hossain Md Imam Sohel , Woobaidullah ASM , Rahman Md Jamilur
Published: March 2018

A sequence stratigraphic analysis was carried out on the sedimentary packages of parts of the Bengal Basin hydrocarbon province. This paper focuses on the identification of petroleum system of Srikail Gas Field within eastern folded belt of Bengal basin using sequence stratigraphic concept. Three strike and five dip seismic lines are used in this work and data analysis is done using Petrel 2015 software. Seismic line-2 (SK-2) of Srikail is good in resolution and is used here only for identifying potential petroleum system. Seven sequence boundaries were identified on the basis of onlap and reflection truncation. The result of the interpreted sequence boundary has revealed that all the elements which are required to generate a potential prospect are present in the study area. Fine grained sediments deposited during the rising and lowering of sea level might act as a potential source rock. Time contour maps of the study area have revealed that the NWSE trending anticlinal Srikail structure is largely affected by shale filled channel in the crestal and western flank. The channel filled shale is later acting as a seal on north and western part of the structure. Erosional remnants truncated against shale fill canyon is acting as prospective reservoirs in the Srikail gas field. The NW-SE trending anticlinal structure and shale fill canyon help this sand as potential traps for hydrocarbon accumulation. Hence the petroleum system of the study area become very prospective in terms of hydrocarbon accumulation.Bangladesh J. Sci. Res. 30(1&2): 1-9, December-2017
Under-five child mortality in Bangladesh: Classical and Bayesian approaches to Cox proportional hazard model
Authors: Nilima Shahnaz
Published: March 2018

This study examines the determinants of under-five child mortality in Bangladesh using the data extracted from the Bangladesh Demographic and Health Survey (BDHS), 2011 and 2014. Product-Limit method and Log-Rank test have been used for bivariate analysis. Cox proportional hazard model has been employed under both classical and Bayesian approaches. Cox regression analysis reveals that region (Barisal and Sylhet), maternal education (higher education), mother’s membership of NGO have significant impact on child mortality. The results obtained using Bayesian Cox PH model are almost similar except one key finding. Under Bayesian analysis, child’s size at birth appeared as potential determinant of under-five mortality whereas it has insignificant effect on child survival when classical Cox model has been applied.Bangladesh J.

Purpose: The present study aimed to identify the learning preferences of dental students and to characterize their relationship with academic performance at a dental school in Isfahan, Iran. Methods: This cross-sectional descriptive study included 200 undergraduate dental students from October to November 2016. Data were collected using a 2-part questionnaire. The first part included demographic data, and the second part was a Persian-language version of the visual, aural, read/write, and kinesthetic questionnaire. Data analysis was conducted with the chi-square test, 1-way analysis of variance, and multiple linear regression. Results: The response rate was 86.6%. Approximately half of the students (51.5%) had multimodal learning preferences. Among the unimodal group (48.5%), the most common mode was aural (24.0%), followed by kinesthetic (15.5%), reading-writing (8.0%), and visual (1.0%). There was a significant association between academic performance and the reading/writing learning style preference (P< 0.01). Conclusion: Multimodal learning styles were the most preferred. Among single-mode learning styles, the aural style was most common, followed by the kinesthetic style. Students with a reading/writing preference had better academic performance. The results of this study provide useful information for preparing a more problem-based curriculum with active learning strategies.
Making Trans Cinema: A Roundtable Discussion with Felix Endara, Reina Gossett, Chase Joynt, Jess Mac, and Madsen Minax
Authors: Rosskam Jules
Published: March 2018

In conversation with Jules Rosskam, trans filmmakers Felix Endara, Chase Joynt, Reina Gossett, Madsen Minax, and Jess Mac explore the contemporary state of trans cinema production, trans methodologies and social practices, the corporeality of cinema, and the relationship between theory and practice. Like somatechnics complicates the term ‘body modification,’ cinema broadens the ways in which we think and talk about films to include the world around the film – the technologies, power(s), relationships, disciplines, spaces, and techniques. The filmmakers discuss the various ways in which their embodied experiences influence and necessitate particular modes of production, reception, and theorization. There is a dynamic and organic movement between the past, present, and future, between dominant and experimental cinemas; one deeply rooted in the urgent intersectionality of trans.
Bodies in Transition: Somatechnics and the Experimental Art of Liselotte Wajstedt'sSámi Nieida Jojk(Sámi Daughter Yoik, 2007)
Authors: Moffat Kate
Published: March 2018

Swedish-Sámi filmmaker and artist Liselotte Wajstedt and her experimental road movie documentary Sámi Nieida Jojk (Sámi Daughter Yoik, 2007) provides a unique insight into displaced Indigenous identity. To explore her mother's repressed Sámi ancestry, Wajstedt uses an eclectic mix of techniques, including animation, collage illustrations, photographs, and superimposition. Throughout the film, Wajstedt uses her body as a physical canvas, projecting images of her autobiographical journey onto herself. These methods contribute to a sense of metamorphosis, where the filmmaker plays with and challenges conventional Sámi representations through film form. I propose that somatechnics, a concept that describes a reciprocal relationship between the body and technology, provides a helpful way of understanding Wajstedt's work. I argue that cinema can work as a somatechnic tool that can help unpack the Indigenous body as a symbol of cultural, geopolitical, and ethnic identity politics. I also explore Sámi Daughter Yoik as a nomadic film, arguing that the somatechnic potential of cinema is most evident when themes of space, transition, and the body converge to create a more fluid understanding of Sámi identity onscreen.
