Study Design

Cross-sectional study.

Background

The drop vertical jump task is commonly used to screen for anterior cruciate ligament injury risk; however, its predictive validity is limited. The limited predictive validity of the drop vertical jump task may be due to not imposing the cognitive demands that reflect sports participation.

Objectives

To investigate the influence of additional cognitive demands on lower extremity mechanics during execution of the drop vertical jump task.

Methods

Twenty uninjured women (age range, 18–25 years) were required to perform the standard drop vertical jump task, as well as drop vertical jumps that included additional cognitive demands. The additional cognitive demands were related to attending to an overhead goal (ball suspended overhead) and/or temporal constraints on movement selection (decision making). Three-dimensional ground reaction forces and lower extremity mechanics were compared between conditions.

Results

The inclusion of the overhead goal resulted in higher peak vertical ground reaction forces and lower peak knee flexion angles in comparison to the standard drop vertical jump task. In addition, participants demonstrated greater peak knee abduction angles when trials incorporated temporal constraints on decision making and/or required participants to attend to an overhead goal, in comparison to the standard drop vertical jump task.

Conclusion

Imposing additional cognitive demands during execution of the drop vertical jump task influenced lower extremity mechanics in a manner that suggested increased loading of the anterior cruciate ligament. Tasks utilized in anterior cruciate ligament injury risk screening may benefit from more closely reflecting the cognitive demands of the sports environment.

Zinc and plastic roofs are used vary widely in poor society because of their low price and their installation easiness. A roof installation with an inclination angle is done in order to the rain water is easy to flow. Rainfall causes noise that has a bad impact to human. This research is aimed to obtaining the effect of inclination angle of zinc and plastic roofs on the noise intensity. The research was done experimentally. The roofs investigated consist of zinc and plastic roofs in waveforms. A room with an overall size of 80 cm x 80 cm x 150 cm was made of wood as the frame. The inclination angles were varied; 10o, 20o, 30o and 40o. The rainfall was modeled by a sprayer with three different water flow rates 0,8; 1,0 and 1,2 lt/s. These flow rates represented low, medium and heavy rains. The noise intensity was measured using a sound level meter, which was placed in the centre of the room. The result shows that increasing the roof inclination angle causes the noise intensity to decrease. The plastic roof has lower noise intensity than the zinc roof. Furthermore, the experimental noise intensity data are relatively safe according to the noise safety level.

Sacrificial anode protection is one type of corrosion protection used to inhibit corrosion rate. The sacrificial anode protection works by utilizing the potential difference between anode and cathode. This research aims to determine the effect of variation in the distribution of quantities and distribution of sacrificial anode aluminum to SS400 steel corrosion rate. The method of calculating the corrosion rate used is the weight loss test. The results of this test indicate that the more uniform distribution of the anode on the surface of the cathode the better the resulting protection will be. The best protection is produced by 4 pieces of sacrificial anode size of 0,5 x 4 cm with an average rate of corrosion rate of 0,1067 mm/year. Protection with 2 pieces of sacrificial anode size 1 x 4 cm resulted in corrosion rate with average value 0,1462 mm/year, while on protection of 1 victim anode with size 2 x 4 cm can produce protection with average value of corrosion rate 0,1677 mm/year. Equivalent distribution of numbers and distributed anodes can narrow the distance between the anodes so that the value of the material's resitivity is smaller and the electrons can be distributed evenly over the entire cathode surface.The corrosion that occurs in SS400 steel is a kind of uniform corrosion. It is seen from the size of the cavity that occurs on each side of the specimen after the immersion process.

The origins of gender identity and gender expression in Anglo-American legal discourse
Authors: Kirkup Kyle
Published: January 2018

Anglo-American lawmakers are in the midst of introducing a series of anti-discrimination protections for trans people. By and large, they are making this change by adding the terms ‘gender identity’ and ‘gender expression’ to a variety of human rights law instruments. In June 2017, for example, the Parliament of Canada passed Bill C-16, An Act to Amend the Canadian Human Rights Act and the Criminal Code. The legislation adds the terms ‘gender identity or expression’ to the Canadian Human Rights Act, along with the hate crimes provisions of the Criminal Code. Similar pieces of legislation have been introduced in the United States and the United Kingdom. While legal scholarship has spent considerable time debating the merits of such legislation, comparatively less attention has been paid to the plural, and often contradictory, history of ‘gender identity’ and ‘gender expression.’ This article traces the origins of these terms, arguing that ‘gender identity’ is the product of mid-century psychiatric discourses that constructed trans people as a narrow class of persons. ‘Gender expression’ is a comparatively newer concept, emerging in the 1990s in concert with performative theories of gender that sought to demonstrate how disciplinary norms are imposed on all members of society. The contemporary reliance on these terms reflects what Eve Kosofsky Sedgwick has called the tension between ‘minoritizing’ and ‘universalizing’ accounts of gender and sexuality. The article is organized in four parts. Part I traces the origins of the term ‘gender identity,’ along with how it migrated from clinical contexts to legal forums. In 1994, the City of San Francisco became the first Anglo-American jurisdiction to entrench the term in a human rights instrument. Part II tracks the comparatively shorter history of the term ‘gender expression.’ The Part then traces the term’s reception into human rights discourse, with New York City becoming the first Anglo-American jurisdiction to use the term ‘gender expression’ in 2000. Part III examines how two terms emerging out of different historical moments and with different sets of normative preoccupations have recently fused together to capture how individuals internally identify their gender and externally perform it. The article concludes by anticipating future implications for the corpus of trans human rights law, which will inevitably continue to grapple with the tension between minoritizing and universalizing approaches.

The USDA–ARS has released a new nuclear male sterile sorghum [Sorghum bicolor (L.) Moench] mutant BTx623ms8 (Reg. No. GS‐786, PI 682727). Previously, seven sorghum nuclear male sterile mutants have been reported, but three are no longer available. Here we register a new nuclear male sterile mutant isolated from a mutagenized BTx623 mutant library that is genetically different from any of the four male sterile mutants currently available. The ms8 mutant had microscopic transparent anthers that abort early during microsporogenesis. It can be easily identified at early stages of anthesis by the appearance of prominent white, hairy stigma, rather than yellow anthers as seen in BTx623 and all other fertile sorghum accessions. We have developed BC6F2 seeds that produce approximately 50% male sterile plants by pollinating the homozygous ms8 mutants with the heterozygous fertile plants. The ms8 is a single recessive nuclear gene mutation and can be easily bred into other sorghum lines through recurrent backcrossing, broadening the utility of this easily recognizable nuclear male sterility.

Authors: Billah Syed Muhammad Baqui , Jahan Muna Shalima
Published: January 2018

Objective: To assess the metabolic syndrome (MetS) status in pre and post menopausal women of Bangladesh.Materials and Methods: Secondary analysis from a cross-sectional study on 276 willing females from an urban and a rural area. The socio-epidemiologic factors were studied with anthropometric examination, blood pressure recording and fasting blood for analysis of triglyceride (TG), high density lipoprotein (HDL), fasting blood sugar (FBS) between pre and post menopausal women.Results and Discussion: Only 19.8% premenopausal women had MetS (95% CI=15.7%-24.7%) compared to that of 50% (95% CI=39.9%-60.1%) menopausal (p<0.001). Low HDL cholesterol prevailed in almost 97% respondents in both groups (p=0.12). The menopausal women had higher TG (51.6%, p=0.07), obesity (10.9%, 0=0.004), high FBS (40.6%, p<0.001) and hypertension (HTN, 32.8%, p<0.001) compared to those of (TG 39.3%, obesity 6.1%, high FBS 19.8% and HTN 9.9% respectively) premenopausal women. On logistic regression, HTN (OR=3.8, 95%CI: 1.9-7.7) and high FBS (OR=2.2, 95%CI: 1.1-4.2) produced significantly higher odds of being associated with menopause. Only menopause became significantly associated with MetS (OR=4.3, 95%CI: 23.0-7.9) after adjusted with residence and education of the respondents.Conclusion: MetS is highly prevalent in post menopausal women in Bangladesh. Women approaching menopause should be brought under health education scheme for awareness of MetS while aging.Bangladesh Journal of Medical Science Vol.17(1) 2018 p.42-46

Published: January 2018

Background: Literature study shows, there are several variations regarding BCCAO duration and duration of reperfusion after BCCAO that can cause cerebral ischemia. Duration of BCCAO techniques varies between 10 to 30 minutes, while the duration of reperfusion period ranging between 45 minutes to 72 hours. Differences in the duration of occlusion, duration of BCCAO reperfusion and the sex of animal model could lead to different responses to ischemia conditions.Objective. This study aims to determine whether the duration BCCAO and sex of the animal models influences the volume of cerebral ischemia after 24 hours reperfusion.Method: This study uses post-test only study group design. The subjects are 20 female and 20 male Wistar rat that being divided into 8 groups which are male rat with occlusion duration of 5 minutes, 10 minutes and 20 minute, also the female rat with occlusion duration of 5 minutes, 10 minutes, 20 minutes respectively. BCCAO occlusion then followed by 24 hour reperfusion. Rat decapitation and brain extraction are done after reperfusion. Brain tissue sliced into 2 mm size and stained with 0.05% TTC solution for 30 minutes. Ischemic brain volume are being observed using Cavalieri method. Statistical data are being analyzed using One Way Anova.Result: There are significant difference in male rat cerebral ischemia volume between 5 minutes and 10 minutes occlusion (p<0.006). Meanwhile, there are no significant difference at cerebral ischemia volume between 10 and 20 minutes occlusion group (p=0.377). There are significant differences in the volume of brain ischemia between the 5, 10 and 20 minutes ischemia group (p<0.05). Post-hoc test showed no significant differences between the male and female rat (p>0.05).Conclusion: Duration of the bilateral common carotid artery occlusion for 5 and 10 minutes affect the volume of cerebral ischemia in male rat after 24 hour reperfusion. The occlusion of bilateral common carotid artery for 5,10 and 20 minutes also affect the volume of cerebral ischemia in female rat after 24 hour reperfusion. No significant differences of cerebral ischemia volume between the sexes after 5, 10 and 20 minutes occlusion.Bangladesh Journal of Medical Science Vol.17(1) 2018 p.129-137

Authors: Rizwan ASM , Islam Md Rakibul , Yusuf Md Ghulam
Published: January 2018

In Bangladesh tuberculosis (TB) cases are fairly common but isolated hepatobilliary TB cases are extremely rare. Liver abscess due to TB without involvement of any other site causes diagnostic delay and can easily confuse with pyogenic or amoebic liver abscess or haepatocellular carcinoma. We present a case of a 44-years-old diabetic,normotensive male who presented with prolonged high grade fever with chill and rigor with tender hepatomegally. He was put on treatment for liver abscess but was not responding. Later on, histopathology was done and it turned out to be a case of tuberculous liver abscess.Bangladesh Journal of Medical Science Vol.17(1) 2018 p.155-157
Literary Intransigence: Between J. Hillis Miller and Ranjan Ghosh
Authors: Van Den Abbeele Georges
Published: January 2018

Hillis Miller and Ranjan Ghosh think literature from opposite but complementary points of view. Miller is the advocate of close reading and generally an inductive approach whereby specific interpretive problems in regard to specific literary texts critically revise broader theoretical assumptions and presuppositions. Ghosh, on the other hand, plays the consummate theorist, appropriating and critically developing various concepts in dialogue with a wide range of contemporary critical voices, then applying that revised/expanded concept to the analysis of specific works. Each models a different way to move between theory and interpretation, but both ground their thinking in the strangeness of literature, what Miller calls its ‘idiosyncrasy’ and Ghosh, based on his reinvigoration of the Hindi term, sahitya, its sacredness. This piece argues for the fundamental ‘foreignness’ of literature (and culture in general) as underwriting both approaches. Following upon Voloshinov, Benjamin, and others, I situate both theory and criticism of literature within the larger problem of translation as a crossing between languages that also brings the foreign into the native tongue, an irreducibility I call literary intransigence. As opposed to platitudes about ‘world’ literature, literary intransigence implies instead a vigorous reading of all literature as foreign.
Literature/Ethics/Reading
Authors: Nayar Pramod K.
Published: January 2018

The chapters on ethics and / of reading in Ranjan Ghosh and J. Hillis Miller's Thinking Literature across Continents propose two models of responding to literature. Ghosh sees literature as embodying a hunger for Otherness. Miller insists on the ethical authority of a given literary work over the reader, its ethical obligations to the characters within and to the readers it addresses, and the ethical acts and decisions of the characters within the work. Ghosh's account of literature as hunger opens up aesthetics to the question of the ethical, including the ethics of representation, reading, and Othering. Along with Miller's formula for reading ethically, the two chapters offer us an approach that may be termed, after Kwame Anthony Appiah, cosmopolitan reading, made possible by the sympathetic imagination that literature embodies.
Surface Waves Propagating on Grounded Anisotropic Dielectric Slab
Authors: Chen Zhuozhu , Shen Zhongxiang
Published: January 2018

This paper investigates the characteristics of surface waves propagating on a grounded anisotropic dielectric slab. Distinct from the existing analyses that generally assume that the fields of surface wave uniformly distribute along the transverse direction of the infinitely large grounded slab, our method takes into account the field variations along the transverse direction of a finite-width slab. By solving Maxwell’s equations in closed-form, it is revealed that no pure transverse magnetic (TM) or transverse electric (TE) mode exists if the fields are non-uniformly distributed along the transverse direction of the grounded slab. Instead, two hybrid modes, namely quasi-TM and quasi-TE modes, are supported. In addition, the propagation characteristics of two hybrid modes supported by the grounded anisotropic slab are analyzed in terms of the slab thickness, slab width, as well as the relative permittivity tensor of the anisotropic slab. Furthermore, different methods are employed to compare the analyses, as well as to validate our derivations. The proposed method is very suitable for practical engineering applications.
Entropy Measures for Stochastic Processes with Applications in Functional Anomaly Detection
Authors: Martos Gabriel , Hernández Nicolás , Muñoz Alberto , Moguerza Javier
Published: January 2018

We propose a definition of entropy for stochastic processes. We provide a reproducing kernel Hilbert space model to estimate entropy from a random sample of realizations of a stochastic process, namely functional data, and introduce two approaches to estimate minimum entropy sets. These sets are relevant to detect anomalous or outlier functional data. A numerical experiment illustrates the performance of the proposed method; in addition, we conduct an analysis of mortality rate curves as an interesting application in a real-data context to explore functional anomaly detection.
