Published: January 2018

In Ethiopia the health system is underdeveloped and much of the rural population has limited access to modern health services. The Ethiopian government introduced the Health Extension Program which is a community-based health care delivery system aimed at accessing essential health services such as malaria treatment through its health extension workers (HEWs). The objective of this study was to evaluate factors influencing malaria treatment practice of health extension workers (HEWs) and patient adherence to antimalarial drugs. A qualitative research design that is explorative and descriptive was used. Data was collected by means of (1) in-depth individual interviews among 20 HEWs, and seven focus group discussions with malaria treated patients. Data was analyzed thematically. Four themes emerged from the data, namely: (1) health facility related factors, (2) HEWs related factors, (3) patient related factors, and (4) community related factors. Improving the availability of essential resources such as rapid diagnostic test kits (RDT) and antimalarial drugs, improving the communityâ€™s perception towards antimalarial drug effectiveness and adequately educating patients on how to take antimalarial drugs can improve malaria treatment practice of the HEWs and patient adherence to antimalarial drugs.

The efficient use of resources on the basis of the development of scientific and technical progress requires widespread implementation of new technologies for processing of metals, such as plas-ma, cathode-ray, detonation and other methods that allow to increase the lifetime of machines operation and reduce the materials and energy consumption throughout production.One of the new highly productive methods for obtaining a high-quality surface is the plasma sur-face processing (gouging) of metals. It is one of the most effective methods for surface pro-cessing applied in modern metal-processing facilities. Unlike other methods for surface pro-cessing this method includes the use of an electric arc and the produced plasma has a tempera-ture which reaches tens of thousands degrees Celsius. At such temperature, not only structural grade steel alloys can be processed, but in-fact all types of metals. The aim of this paper is to investigate the relation between the technological parameters of the process air-plasma surface gouging and the quality characteristics of the obtained surface lay-ers.The relations between technological parameters of the process air-plasma surface gouging of metals and quality parameters were obtained by using rotatable design of experiments and re-gression analyses techniques.

Prediction and Measurement of Pressure Drop of Water Flowing in a Rectangular Microchannel
Authors: Mirmanto M.
Published: January 2018

This paper presents experimental results of pressure drop measurement and prediction of water flowing through a copper rectangular microchannel with a hydraulic diameter of 437 µm. The aim of this work is to identify discrepancies between experimental data and macrochannel theory. An inlet temperature of 60oC was kept constant at the channel entrance and the experiments were performed with Reynolds numbers (based on the mean velocity and hydraulic diameter) ranging up to 4500.  The results show that the pressure drop prediction agrees with the theory. However, the trend of Poiseuille number with the Reynolds number was not constant for laminar flow. This could be due to the entrance effect. Moreover, the friction factor theory could predict the experimental data for turbulent flow. Thus, in this experiment, the theory for flow in macro passages is still applicable.

ABSTRACTDue to population growth, industry advance and rapid development, fresh and comfortable air may be difficult to get. Conditioning the air to get comfort environment may be a basic demand for people, but the prices of the device and its operation for this purpose are expensive. This research tries to solve this problem but it is just only to know the capability of the heat exchanger  to transfer/ absorb heat and is not to cool the room to be below the ambient temperature. The working fluid used was clean water and the heat exchangers employed were parallel and serpentine which were made of copper pipes with a diameter of 1/4 inch and 1/2 inch (for the header). The volumetric flow rates used were 300 ml/minutes, 400 ml/minutes and 500 ml/minutes. While the heat that should be absorbed by the water from the room is 50 W, 100 W and 150 W. The results show that the effect of volumetric flow rate on heat exchanger performance and room temperature is insignificant. From the pressure drop results, the parallel pipe heat exchanger has lower pressure drops while the serpentine has higher pressure drops.

Don’t be so hateful: The insufficiency of anti-discrimination and hate crime laws in improving trans well-being
Authors: Ashley Florence
Published: January 2018

The question of judicial protection of trans people has come to the fore in recent years, culminating in Bill C-16 which added gender identity and gender expression to the federal anti-discrimination and hate crime laws. In this article, the author contests the notion that anti-discrimination and hate crime laws are effective in mitigating anti-trans harassment, discrimination, and violence. Suggesting that the model of anti-trans acts which underlies anti-discrimination and hate crime laws is erroneous, the author argues that the law’s impact on trans well-being will be modest and that a careful analysis of anti-trans attitudes enables us to identify a number of more effective governmental avenues toward trans emancipation.
The management of Premenstrual syndrome: A review
Authors: Malik Rabia , Bhat Muzafar Din Ahmad
Published: January 2018

Premenstrual Syndrome is a set of physical, emotional and behavioural symptoms that start during the week preceding menstruation and are alleviated when the menstrual flow begins. Epidemiological surveys have estimated that the frequency of PMS symptoms is about 80-90% with impairment of functioning. Women with severe PMS should be managed by a multi disciplinary team, which might comprise a hospital or community gynaecologist, psychiatrist or psychologist, dietician and counselor. Where there is multidisciplinary provision of care, this is of benefit both from the diagnostic and therapeutic point of view, giving the ability to offer a broad range of interventions from lifestyle interventions and cognitive behavioural therapy (CBT) to gynaecological interventions.Bangladesh Journal of Medical Science Vol.17(1) 2018 p.16-20

Published: January 2018

Introduction: Hysterectomy is the most commonly performed gynaecological surgery in India as well as in abroad. It is frequently done in myometrial and endometrial pathologies and rarely for other causes. Hysterectomy is definitive management for diseases like fibroid, adenomyosis, dysfunctional bleeding, prolapsed uterus and malignant lesions of uterus and adenexa. We aimed our study to observe incidence of different pathologies of uterus and other reproductive organs in hysterectomy specimens and retrospective correlation between clinical diagnosis and histopathological finding of hysterectomy cases.Materials and Methods: Retrospective data were collected from our routine histopathological laboratory. Detailed history, clinical examination and operative findings and provisional diagnosis of all 950 hysterectomy cases were recorded during study period of 2 years. Histopathological diagnosis was correlated with clinical and preoperative diagnosis.Observations: Abdominal hysterectomy (734 cases, 77.26%) was the most common route of approach during surgery. Common pre-operative diagnoses were fibroid uterus (32%), dysfunctional uterine bleeding (28.95%), uterine prolapsed (22.74%). Other causes included uterine polyps (1.6%), complications of pregnancy (2.74%), ovarian tumours (8.42%), cervical carcinomas (2.97%) etc. Common pathologies on histology were leiomyoma (32%), adenomyosis (20.32%), atrophic endometrium (17.26%) and endometrial pathology (8.95%).Discussion: Our study has been correlated with other studies of India and other south Asian countries. Most common indication of hysterectomy in our study is dysfunctional uterine bleeding (32%) but Gupta et al and Jha R et al found utero-vaginal prolapse as most common indication. Leiomyoma was the most common histology diagnosed in the present series. Clinical diagnosis was possible in 67.57% cases in our study similar to Khan et al (70.51%).Conclusions: Histopathological examination of hysterectomy specimens helps to detect the exact causes and underlined pathology.Bangladesh Journal of Medical Science Vol.17(1) 2018 p.88-92

Crossing Continents
Authors: Colebrook Claire
Published: January 2018

This essay works through Ranjan Ghosh and J. Hillis Miller's co-authored work on thinking across continents. Taking both authors at their word I explore two senses of the continent, both of which threaten to wreak havoc on any simple or benevolent exercise of cross-cultural exchange. The first sense of continent pertains to continuity, a sense of extensive or connected land; a sense that is bound up with identity and capture. The second sense of continent hearkens back to restraint. Thinking about literature and its specific mode of inscription precludes any continuous or restrained plane of writing. What it might mean to think across continents would almost certainly require crossing our fixed sense of the continent out, and of writing incontinently.

Published: January 2018

The characteristic of interaction with various enzymes and processivity-promoting nature during DNA replication makes β-clamp an important drug target. Helicobacter pylori (H. pylori) have several unique features in DNA replication machinery that makes it different from other microorganisms. To find out whether difference in DNA replication proteins behavior accounts for any difference in drug response when compared to E. coli, in the present study, we have tested E. coli β-clamp inhibitor molecules against H. pylori β-clamp. Various approaches were used to test the binding of inhibitors to H. pylori β-clamp including docking, surface competition assay, complex structure determination, as well as antimicrobial assay. Out of five shortlisted inhibitor molecules on the basis of docking score, three molecules, 5-chloroisatin, carprofen, and 3,4-difluorobenzamide were co-crystallized with H. pylori β-clamp and the structures show that they bind at the protein-protein interaction site as expected. In vivo studies showed only two molecules, 5-chloroisatin, and 3,4-difluorobenzamide inhibited the growth of the pylori with MIC values in micro molar range, which is better than the inhibitory effect of the same drugs on E. coli. Therefore, the evaluation of such drugs against H. pylori may explore the possibility to use to generate species-specific pharmacophore for development of new drugs against H. pylori.
A Modal Solution for Finite Length Rods with Non-Uniform Area
Authors: Hull Andrew
Published: January 2018

This paper derives a modal solution to the displacement field of a finite length rod whose area varies with respect to its length. This new method facilitates a solution to any problem where the area and derivative of the area can be represented as analytical functions. The problem begins by writing the longitudinal displacement of the non-uniform area rod as a series of indexed coefficients multiplied by the eigenfunctions of the uniform area rod. This series solution is inserted into the non-uniform area rod equation and multiplied by a single p-indexed eigenfunction. This equation is then integrated over the interval of the rod. Although the resultant expressions are not orthogonal, they can be written as a set of linear algebraic equations which can be solved to yield the unknown coefficients. Once these are known, the displacement of the system can be calculated. Five example problems are included: the first one has a non-uniform area that corresponds with a known analytical solution, the second has an area that can be represented by a Fourier series, the third and fourth have areas that do not have a known analytical solution and the fifth is a generic second order non-constant coefficient differential equation. Four of these problems are verified with other methods. Convergence of the series solution is discussed. It is shown that this new model is almost two orders of magnitude faster than corresponding finite element analysis.
Poisoning Effect of SO2 on Honeycomb Cordierite-Based Mn–Ce/Al2O3Catalysts for NO Reduction with NH3 at Low Temperature
Authors: Wang Chengzhi , Zhang Cheng , Zhao Yonggang , Yan Xin , Cao Peng
Published: January 2018

Honeycomb cordierite-based Mn–Ce/Al2O3 catalysts were prepared by the impregnation method and used for low-temperature selective catalytic reduction (SCR) of NOx with NH3, with and without SO2 and/or H2O in a homemade fixed-bed tubular reactor. The catalyst reached nearly 80% NOx conversion at 100 °C in the absence of SO2. However, SO2 reduces the catalytic activity (80% to 72%) of the honeycomb cordierite-based Mn–Ce/Al2O3 catalysts under identical conditions. This finding demonstrated that the catalyst exhibited high activity at low temperature and excellent SO2 resistance in the presence of 50 ppm SO2. The fresh and sulfated honeycomb cordierite-based Mn–Ce/Al2O3 catalysts were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), N2 adsorption–desorption, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetry and differential thermal analysis (TG-DTA), and Fourier transform infrared (FT-IR) spectroscopy. Characterization results indicated that the deactivation by SO2 was primarily the result of the deposition of ammonium hydrogen sulfate and sulfated CeO2 on the catalyst surface during the SCR process. The formed sulfates depressed the catalytic activity via the blocking of pores and the occupation of active sites. Additionally, the competitive adsorption between SO2 and NH3 always decreased the catalytic activity.
