Numerical Investigation of the Effect of Inserted Twisted Tape inside Submerged Bundle Tubes on its Thermal Performance
Authors: Ali Kamal Mohammed , Abbas Abdalrazzaq K.
Published: June 2018

Twisted tape insertion in the smooth plain tube is one of the types of passive methods that are used to enhance heat transfer. Swirl fluid flow inside the tube and related heat transfer characteristics are very complex. ANSYS FLUENT (V 16.1) and ASPEN industrial program are used in analyzing this technique for enhancement heat transfer. A circular plain tube has length L=8534mm and 17 mm inner diameter with a twisted tape of twist ratio of y = (H/D) = (150/17) =8.8 along the plain tube were considered for this study. Eight Reynolds numbers (Re) of 784, 1000, 2000, 3000, 4000, 5000, 6000 and 7000 are used to analyze the response of thermal performance. Crude oil API 28 exit temperature, film heat transfer coefficient, Nusselt number and overall enhancement ratio results are presented for both empty and inserted plain tube with a comparison between the two cases. An increase of 0.76 to 2.36 overall enhancement is predicted with twist ratio 8.8 for Reynolds number 784 to 7000 respectively.

Authors: Hussein Maha Ali
Published: June 2018

An experimental investigation has been made to study the influence of using v-corrugated aluminum fin on heat transfer coefficient and heat dissipation in a heat sink. The geometry of fin is changed to investigate their performance. 27 circular perforations with 1 cm diameter were made. The holes designed into two ways, inline arrangement and staggered in the corrugated edges arrangement. The experiments were done in enclosure space under natural convection. Three different voltages supplied to the heat sink to study their effects on the fins performance. All the studied cases are compared with v-corrugated smooth solid fin. Each experiment was repeated two times to reduce the error and the data recorded after reaching the steady state conditions. The results showed that the v-corrugated fin dissipate heat twice and triple times than flat plate mentioned in past research with the same dimension. Also, the inline perforated fin gave higher enhancement percentage than solid one by 15, 32 and 36% for 110, 150 and 200 V voltages supplied. Finally, the staggered perforation arrangement gave the higher enhancement percentage with 22, 42 and 45% for the same voltages supply.

Authors: Abdul-Majeed Mohammed Amer
Published: June 2018

In this study, polymeric ultrafiltration (UF) membranes were prepared by phase inversion method to obtain both antibacterial and organic antifouling properties. The membranes were cast from a solution of polyvinylidene fluoride (PVDF) and formative silver (Ag) nanoparticles were successfully immobilized on a polymer. This was done using a solvent N, N-dimethylformamide (DMF) which is a solvent for the PVDF polymer meanwhile it is a reducing agent for silver ion. The effect of silver nanoparticles additives on the performance of polymeric ultrafiltration membrane was verified. Chemical composition and morphology of the surfaces of the membranes were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The antibacterial property of modified membrane and the influence of silver nanoparticles on pure water flux of composite membrane at 0.2 Mpa were also verified. The experimental results obtained concluded that the composite membrane properties have been improved by the integration of Ag nanoparticles. The grafted membrane with silver nanoparticles has shown a clear ability to inhibit the growth of E. coli, Pseudomonas Aeruginosa, and Bacillus Cereus. While the clean PVDF membrane (without any additives) did not show any effect of preventing the growth of these species of bacteria referred to above. The pure water flux, porosity and the mean pore size of composite membrane can reach 261.8 L/m2 h, 85.4%, and 0.0206 µm, respectively, and it was much more than that of pure PVDF membrane.

Published: June 2018

Pigs play a key role in inter-species transmission of influenza virus, because they have receptors to both avian and human influenza viral strains. A study was conducted in three different districts namely Bhaktapur, Kavre and Banke with face to face type of questionnaire survey and serum sample collection. Indirect Enzyme Linked Immunoassay was utilized for the collected 231 samples for serologic evidence of influenza A. Of the total 231 samples tested, 11 were positive for Influenza virus A with an overall sero-prevalence of (4.76%; Cl95%: 2.68-8.324) Kavre district had highest (5.88%; Cl95%: 2.539-13.04) sero-prevalence, followed by Bhaktapur (5.13%; Cl95%: 2.012-12.46) and Banke (2.94%; Cl95%; 0.8104-10.1) with no significant difference (p=0.685). Rearing swine along with poultry was the most significant risk factor (p=0.03); all positive cases were from the farms that adopted integrated farming system with little to no bio-security measures, especially poultry and swine. Present finding depicts that Influenza A is prevalent in pig farms of Kavre, Banke and Bhaktapur. Further research is needed to sub-type the influenza virus and also determine the effect of commercial poultry and migratory birds on the outbreak of influenza A in swine.  Int. J. Appl. Sci.

In order to contribute to cotton cultivation sustainability in west central Côte d'Ivoire, a phytosanitary diagnostic study was conducted in 11 plots. It consisted of monitoring the sanitary condition of 10 rural plots and an experiment plot set up at the Research Farm of University Jean Lorougnon Guédé of Daloa according to the regular and careful inspection of cotton seed germination, seedling health and cotton plants throughout the growing season. The results obtained indicated that the cotton varieties used by farmers had very low germination with maximum number of healthy seedlings of 43.75 % in an experiment condition. Highest number of infected seedlings (24-51%) showing characteristic symptoms of seedling blight leading to their death was observed. Under cultivation, a variety of pests was identified on cotton plants. The most important were Bemisia tabaci, Jacobiella fasciali, Helicoverpa armigera, Dysdercus sp, Earias sp, Zonocerus Variegatus, Haritalodes derogata. The Species Zonocerus Variegatus and Haritalodes derogata proved to be devastating on the experimental plot where 100% loss was recorded. The main disease observed at flowering stages in cotton plants was cotton virescence disease. Although lowly infection were observed (0.11 -0.35%) cotton cultivation monitoring and management must be set up so as to prevent its expansion in the west central. Theses finding gives useful information to farmers to reduce cotton yield losses in west central Côte d'Ivoire.Int. J. Appl. Sci. Biotechnol. Vol 6(2): 152-157
Dilemma and Factionalism in the Maoist Politics of Nepal
Authors: Ayadi Arjun Bahadur
Published: June 2018

The history of the Communist movement of Nepal has passed almost 70-years since the formation of the Communist Party of Nepal (CPN) in 1949. During this period, the Communist movement of Nepal passes through so many ups and downs, twists and turns, and defeats and victories. It has taken different paths in course of its development. It has experienced series of split and merger, which still continues. The Maoist, a radical faction of the communist movement, led the armed struggle for ten-years between 1996-2006 to seizes political power and establish a “New People’s Democracy”. However, the deadly armed struggle concluded in negotiation after 10-year and Maoists re-entered in the competitive politics. As it entered in the competitive politics, the CPN (Maoist), revised its ideological goal from “New People’s Democracy” to “Democracy in the Twenty First Century”. After these ideological change, it has entered in the vicious circle of split and merger. In this context, this paper aims to understand the relations between political dilemma and fraction taken place in the history of Communist movement of Nepal in general and Maoist politics in particular. On the basis of documentary analyses, this paper argues, the whole Communist movement of Nepal including Maoists politics suffered from ideological dilemma (between liberal and radical line) that resulted internal contradiction within the movement leading toward the series of split and generated the serious crisis to radical politics in Nepal.Journal of Political Science, Volume XVIII, 2018, page: 1-24
The need of Change in Contemporary Nepalese Foreign Policy
Authors: Dahal Ram Kumar
Published: June 2018

The year 2017 has witnessed important changes in Nepal including the holding of Central, Provincial and Local elections in course of implementing the federal constitution-the constitution of Nepal, 2015. Besides these national changes, important changes have occurred in regional and global politics. In the changed national, regional and global context, Nepal has to readjust, reorient and reformulate its foreign policy to serve the growing needs and aspirations of its people. Both the internal and external issues and challenges have to be timely and properly addressed by means of an appropriate contemporary Nepalese foreign policy. The nonaligned foreign policy formulated during the cold war period has to develop new mechanisms and capabilities to cope with the changing time and situation, to fulfill the growing aspirations and expectations of the Nepalese people in the present context and to maintain its independent regional and global image and personality. In this context, Nepal has to realize the significance of its specific, unique and peculiar characteristics and convert/transform them as elements of national power and contribute towards strengthening/consolidating its foreign policy.Journal of Political Science, Volume XVIII, 2018, Page: 82-113

The issue of indigenous and non-indigenous, minorities and the majority has become an exaggerated issue causing the sentiment and the disturbance of relations between ethnic minorities and ethnic majority. This article was intentionally written to see a portrait of harmony between ethnic Minang and Tionghoa in Padang City. Lately it is so easy to insult and degrade the religion of others. Therefore, this article aims to provide awareness to the parties who deliberately divide relations and harmony among tribes, religions, races and groups in Indonesia. One of portraits of inter-ethnic and inter-religious harmony can be seen in West Sumatra. The ability of ethnic Chinese to be ethnic Minang who use matrilineal system by emphasizing the element of motherhood makes the potential of conflict can be minimized.  The harmony between the two ethnics could frequently end with inter-ethnic marriage.

Melioidosis, a “great mimicker,” is a potentially severe and fatal illness. In this paper we present a Québec case of imported pulmonary melioidosis in a young patient who failed to demonstrate any of the risk factors traditionally associated with progression to clinical disease. Although reported cases of imported disease in Canada are exceedingly rare, a surge of cases in the Caribbean and sporadic autochthonous cases in the United States increase the likelihood that we will encounter more cases in Canada.

Published: June 2018

Aujourd’hui on constate une forte hétérogénéité des opérations de LBO et l’apparition d’un nouveau « business model » chez les sociétés de Private Equity. Alors que les fonds s’assuraient d’une baisse des coûts chez les sociétés cibles de LBO avant de les revendre rapidement, du fait de la crise et du manque de cibles, ils adoptent une vision de plus long terme. En effet les fonds tentent de détecter des entreprises à potentiel fort et les aident à le réaliser. Ceci explique en partie la croissance des opérations de LBO secondaire. L’objectif est, à l’aide d’une revue de la littérature, d’apprécier la diversité de ces opérations et les performances des firmes cibles, puis de comprendre l’évolution de la stratégie des fonds en période de crise, de coût de la dette faible, et de marché boursier perturbé.
Introduction

Published: June 2018

People at the popular level often hold religious perceptions and engage in
religious practices that make sense to them within their own existential situations,
even if they fall outside orthodoxy. Although political leaders and religious
authorities may attempt to mould people’s religious perceptions and practices
according to their own ideas and interpretations of religion, people frequently
find ways to evade or ignore such pressures, to rationalise their deviations or
to continue to live and think according to their own self-generated religious
frameworks. The authors of the articles in this special issue provide examples of
how people’s actual practices and religious beliefs arise out of their own personal
situations and histories though at odds with the pronouncements of religious
specialists.
Understanding the Zār
Authors: Beeman William O.
Published: June 2018

This article explores the structure and meaning of the Zār ceremony
as carried out throughout the Persian Gulf. This ceremony is mirrored by similar
ones throughout North and East Africa, suggesting that the Zār may have resulted
from cultural diffusion along historical trade routes. The Zār practitioners, the
bābā and the māmā, must cultivate extensive skills in musical performance,
movement and coordination in order to affect a palliative relief for persons affected
by spirit ‘winds’ that inhabit them, causing physical and emotional distress. The
Zār ceremony is an important method of non-allopathic treatment for emotional
disorders that might elsewhere be treated through psychiatry in clinical settings.
Practitioners see it as compatible with Islam, though not a strictly Islamic practice.
Economic Transitions and Land Ownership
Authors: Melkumyan Hamlet , Hovsepyan Roman
Published: June 2018

The Yezidis of Armenia, traditionally considered transhumant
pastoralists, have been changing their economic habits over the past century.
Nowadays, they are more engaged in agriculture than they were a century ago. The
social and cultural backgrounds of these transformations are discussed, showing
the involvement of the treatment of the Armenians and the adaptive character of
the Yezidis’ economy. Presently, the Yezidis practise animal breeding and plant
cultivation in parallel, using the human resources available in their family. The
ongoing transformations in the economy and their engagement in agriculture are
challenging the conservative lifestyle of the Yezidi community. Thus, the people
who have shifted to the agrarian economy are seen as outsiders in the traditional
framework and are perceived to be of low prestige.

OBJECTIVE

Intraplaque hemorrhage (IPH) is most often caused by the rupture of neovessels; however, the factors of intraplaque neovessel vulnerability remain unclear. In this study, the authors focused on pericytes and aimed to investigate the relationship between IPH and pericytes.

METHODS

The authors retrospectively analyzed the medical records of all patients with carotid artery stenoses who had undergone carotid endarterectomy at their hospitals between August 2008 and March 2016. Patients with carotid plaques that could be evaluated histopathologically were eligible for study inclusion. Intraplaque hemorrhage was analyzed using glycophorin A staining, and patients were divided into the following 2 groups based on the extent of granular staining: high IPH (positive staining area > 10%) and low IPH (positive staining area ≤ 10%). In addition, intraplaque neovessels were immunohistochemically evaluated using antibodies to CD34 as an endothelial cell marker or antibodies to NG2 and CD146 as pericyte markers. The relationship between IPH and pathology for intraplaque neovessels was investigated.

RESULTS

Seventy of 126 consecutive carotid stenoses were excluded due to the lack of a specimen for histopathological evaluation; therefore, 53 patients with 56 carotid artery stenoses were eligible for study inclusion. Among the 56 stenoses, 37 lesions had high IPH and 19 had low IPH. The number of CD34-positive neovessels was equivalent between the two groups. However, the densities of NG2- and CD146-positive neovessels were significantly lower in the high IPH group than in the low IPH group (5.7 ± 0.5 vs. 17.1 ± 2.4, p < 0.0001; 6.6 ± 0.8 vs. 18.4 ± 2.5, p < 0.0001, respectively).

CONCLUSIONS

Plaques with high IPH are associated with fewer pericytes in the intraplaque neovessels. This finding may help in the development of novel therapeutic strategies targeting pericytes.
A football helmet prototype that reduces linear and rotational acceleration with the addition of an outer shell

OBJECTIVE

Amid the public health controversy surrounding American football, a helmet that can reduce linear and rotational acceleration has the potential to decrease forces transmitted to the brain. The authors hypothesized that a football helmet with an outer shell would reduce both linear and rotational acceleration. The authors’ objectives were to 1) determine an optimal material for a shock-absorbing outer shell and 2) examine the ability of an outer shell to reduce linear and/or rotational acceleration.

METHODS

A laboratory-based investigation was undertaken using an extra-large Riddell Revolution football helmet. Two materials (Dow Corning Dilatant Compound and Sorbothane) were selected for their non-Newtonian properties (changes in viscosity with shear stress) to develop an outer shell. External pads were attached securely to the helmet at 3 locations: the front boss, the side, and the back. The helmet was impacted 5 times per location at 6 m/sec with pneumatic ram testing. Two-sample t-tests were used to evaluate linear/rotational acceleration differences between a helmet with and a helmet without the outer shell.

RESULTS

Sorbothane was superior to the Dow Corning compound in force reduction and recovered from impact without permanent deformation. Of 5 different grades, 70-duro (a unit of hardness measured with a durometer) Sorbothane was found to have the greatest energy dissipation and stiffness, and it was chosen as the optimal outer-shell material. The helmet prototype with the outer shell reduced linear acceleration by 5.8% (from 75.4g to 71.1g; p < 0.001) and 10.8% (from 89.5g to 79.8g; p = 0.033) at the side and front boss locations, respectively, and reduced rotational acceleration by 49.8% (from 9312.8 rad/sec2 to 4671.7 rad/sed2; p < 0.001) at the front boss location.

CONCLUSIONS

Sorbothane (70 duro) was chosen as the optimal outer-shell material. In the outer-shell prototype helmet, the results demonstrated a 5%–10% reduction in linear acceleration at the side and front boss locations, and a 50% reduction in rotational acceleration at the front boss location. Given the paucity of publicly reported helmet-design literature and the importance of rotational acceleration in head injuries, the substantial reduction seen in rotational acceleration with this outer-shell prototype holds the potential for future helmet-design improvements.
Invalid certificates in modern browsers: A socio-technical analysis
Authors: Giustolisi Rosario , Bella Giampaolo , Lenzini Gabriele
Published: June 2018

The authentication of a web server is a crucial procedure in the security of web browsing. It relies on certificate validation, a process that may require the participation of the user. Thus, the security of certificate validation is socio-technical as it depends on traditional security technology as well as on social elements such as cultural values, trust and human-computer interaction.

This manuscript analyzes extensively the socio-technical security of certificate validation as carried out through today’s most popular browsers. First, we model processes, protocols and ceremonies that browsers run with servers and users as UML activity diagrams. We consider both classic and private browsing modes and focus on the certificate validation. We then translate each UML activity diagram to a CSP# model. The model is expanded with the LTL formalization of five socio-technical properties pivoted on user involvement with certificate validation. We automatically check whether the CSP# models are socio-technically secure against Man-in-the-Middle attacks using the PAT model checker. The findings turn out to be far from straightforward. From them, we state best-practice recommendations to browser vendors.

We therefore considered 31 patients with HBI, to determine the serum levels of inflammatory markers (C-Reactive Protein, CRP and or interleukine-6, IL-6) to establish their impact on functional status (Functional Independence Measure, FIM: 18 indicating the worst performance and 126, a normal score).

RESULTS:

The results showed an inflammation prevalence (CRP >0.5 mg/dl and/or IL 6 >7 pg/ml) of 74.2% at admission to Rehab. FIM reduction was more pronounced in inflamed compared to non-inflamed subjects ( p <  0.05) and significantly correlated with blood variables sensitive to inflammation, such as alpha 1 globulin ( r = – 0.565) and neutrophil/ lymphocyte ratio ( r = – 0.52), CRP ( r = – 0.365). At discharge from Rehab, the inflammation rate diminished. Inflamed patients showed similar gains in FIM score as their controls. In the entire population, the FIM gain was significantly associated with a gain in serum albumin, only ( r = +0.56).

CONCLUSIONS:

We conclude that systemic inflammation is prevalent in HBI patients and contributes to reduce patient functional status. However, during the Rehab stage, inflammation does not hinder the improvement rate of functional capacity.
Calcidiol serum levels and blood pressure responses in normotensive patients with dietary goat milk
Authors: Yusni Yusni
Published: June 2018

Background: Calcidiol (25-hydroxyvitamin D or 25(OH) D) is the active form of vitamin D that can be measured in the blood. Vitamin D functions as a regulator of blood pressure and a vitamin D deficiency is associated with an increased risk of hypertension. Goat’s milk is thought to have anti hypertensive effect. That is likely due to the amount of vitamin D found in goat’s milk, but requires further investigation. This research was conducted to analyze the effect of consuming goat’s milk on blood pressure and its relationship with calcidiol serum in normotensive patients.Materials and Methods: The design of this research was experimental laboratory with randomized pretest-posttest with a control group using 18 sedentary women aged 18-19 years. The treatment was 250 ml/day of goat’s milk given in the morning after breakfast for 110 days. The data were analyzed by the statistical t-test (p<0.05).Results: A significant decrease of systolic blood pressure (p=0.00) and no significant decrease of diastolic blood pressure (p=0.51) were observed in the trial group. Levels of calcidiol serum did not increase significantly (p=0.06) after consuming goat’s milk in the trial group.Conclusion: It can be concluded that goat’s milk can decrease blood pressure but does not affect calcidiol serum in normotensive patients. Further research is needed to determine the effect of goat’s milk on blood pressure in hypertensive patients.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.337-341

Collected primary data were analyzed using the Statistical Package for the Social Sciences version 14.015.Results: Male (69.63%) students and students of schools in the town (84.97%) performed better. Majority of the students in towns (46.85%; 49.65%) and villages (45.51%; 50.90%) drank dairy milk and ate meat respectively, once or twice in a week. Many students in towns (30.77%) and villages (38.92%) ate eggs for 3 to 4 days in a week. Maximum students in town (53.50%) and in village (46.71%) took fish for 5 to 7 days and 3 to 4 days in a week, respectively. Many students in town (39.86%) and in village (59.88%) took fruits 1 to 2 days and 5 to 7 days in a week, respectively. Most (74.31%) of the students who took dairy milk, meat (73.68%), fruits (66.67%), fish (65.81%) and eggs (64.71%) everyday in a week obtained A grade.Conclusions: Schools, availability of dairy milk, meat, fruits, fish and eggs, Tiffin intake status and gender affected the academic performances but educational institutions had no effect on weekly dairy milk, eggs and meat intake of the students but weekly fish and fruits intake status were affected.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.355-359

Aim of study: To assess knowledge, attitude and practice of primary care physicians offering primary health care (PHC), toward adult vaccination and their own vaccination coverage as well as to identify reasons for low vaccination coverage.Methodology: A cross-sectional study design, this study included 103 PHC physicians in Abha City. A self-administered questionnaire was designed by the researcher for data collection.Results: About three fourths of PHC physicians (73%) had poor knowledge, while 21% had moderate knowledge and only 6% had good knowledge, while 41% had positive attitude toward adult vaccination, 49% had neutral attitude while 10% had negative attitude. Most PHC physicians (70%) had poor practice regarding adult vaccination, while 20% had moderate practice and 10% had good practice. PHC physicians’ knowledge was significantly better among older and non-Saudi physicians (p<0.001 and p=0.001, respectively). PHC physicians’ positive attitude toward adult vaccination was significantly higher among female participants (p=0.013), among Non-Saudi physicians (p=0.004) and among those with experience in primary health care more than 10 years (p=0.044). PHC physicians’ good practice regarding adult vaccination was significantly higher among older physicians and among those with experience in primary health care more than 10 years (p=0.004). The most frequently stated reasons for low adult vaccination coverage were “Lack of coordinated immunization programs for adults” (63.1%), “Physicians do not inform patients about adult vaccination because they do not have enough time” (61.2%) and “Lack of availability of up-to-date records and recording systems” (55.3%).Conclusions: Knowledge of PHC physicians in Abha City regarding adult vaccination is suboptimal. Most of them do not have negative attitude toward adult vaccination. Their practice regarding adult vaccination is mostly poor. There are several obstacles against implementing vaccination of adults.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.369-381

Authors: Arquez Humberto Ferreira
Published: June 2018

Background: The blood supply of the hand is complex and challenging. Awareness of the anatomical variationis necessary not only for the anatomist but also for surgeons.The ulnar artery provides a major blood supply to the hand with the assistance of the radial artery in the form of the superficial palmar arch.The objective of this study was reported a rareanatomical variation of the superficial palmar arch.Materials and Methods: The anatomical variation described was found during routine dissection performed by medical students of second semester in a 75-year-old male embalbed adult cadaver in the laboratory of Morphology of the University of Pamplona.Results and Discussion: In the right hand, the superficial palmar arch only gave rise to two common palmar digital arteries. In the left hand, the arch provided common palmar digital arteries which ran into the first, third and the fourth spaces and one proper palmar digital for the little finger. The arch does not supply the second intermetacarpal space.Conclusions: Less critical knowledge of vasculature of the hand might lead iatrogenic injury during surgery, microvascular surgery for revascularization, replantation and composite tissue transfers.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.496-500

Foreign body denture is common among edentulous adults because of decrease the sensitivity of the oral cavity. Carelessness in handling dentures and failure to seek early medical attention even the denture has broken are among the contributing factors. Persistence of symptoms with normal radiograph findings still require further actions which include surgical intervention. Rigid esophagoscopy remain as standard treatment modality for removal of foreign body.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.515-517
