Authors: Anil Kumar Naik B. , Vinod A. V. 
Published: November 2017

Abstract
The rheological behavior and effective thermal conductivity of CMC-based non-Newtonian nanofluids were investigated. Non-Newtonian nanofluids of different concentrations were prepared by dispersing Fe2O3, γ-Al2O3 and CuOnanoparticles in three different concentrations of (0.5, 0.75, and 1.0 wt. %) aqueous carboxymethyl cellulose (CMC) solution (base fluid). Experiments were carried out to examine the effect of concentration of nanofluid and temperature on rheological behavior and effective thermal conductivity of non-Newtonian nanofluid. Viscosity and thermal conductivity were measured by rheometer and transient hot wire technique, respectively. The rheological characterization and thermal conductivity measurements were done in the range 30°C–50°C. Flow behavior index and consistency index were determined. As the concentration of nanofluid and temperature were increased, the thermal conductivity of nanofluid was found to increase. A correlation for predicting the thermal conductivity of non-Newtonian nanofluid was developed. The correlation predicted the thermal conductivity of non-Newtonian nanofluids reported by other researchers very well. The results obtained were compared with the model predictions from literature.
MicroRNA Tissue Atlas of the Malaria Mosquito Anopheles gambiae
Authors: Lampe Lena , Levashina Elena A 
Published: November 2017

Abstract
Anopheles gambiae mosquitoes transmit the human malaria parasite Plasmodium falciparum, which causes the majority of fatal malaria cases worldwide. The hematophagous lifestyle defines mosquito reproductive biology and is exploited by P. falciparum for its own sexual reproduction and transmission. The two main phases of the mosquito reproductive cycle, previtellogenic (PV) and postblood meal (PBM), shape its capacity to transmit malaria. Transition between these phases is tightly coordinated to ensure homeostasis between mosquito tissues and successful reproduction. One layer of control is provided by microRNAs (miRNAs), well-known regulators of blood meal digestion and egg development in Aedes mosquitoes. Here, we report a global overview of tissue-specific miRNAs (miRNA) expression during the PV and PBM phases and identify miRNAs regulated during PV to PBM transition. The observed coordinated changes in the expression levels of a set of miRNAs in the energy-storing tissues suggest a role in the regulation of blood meal-induced metabolic changes.
Comparison of ChIP-Seq Data and a Reference Motif Set for Human KRAB C2H2 Zinc Finger Proteins

Published: November 2017

AbstractKRAB C2H2 zinc finger proteins (KZNFs) are the largest and most diverse family of human transcription factors, likely due to diversifying selection driven by novel endogenous retroelements (EREs), but the vast majority lack binding motifs or functional data. Two recent studies analyzed a majority of the human KZNFs using either ChIP-seq (60 proteins) or ChIP-exo (221 proteins) in the same cell type (HEK293). The ChIP-exo paper did not describe binding motifs, however. Thirty-nine proteins are represented in both studies, enabling the systematic comparison of the data sets presented here. Typically, only a minority of peaks overlap, but the two studies nonetheless display significant similarity in ERE binding for 32/39, and yield highly similar DNA binding motifs for 23 and related motifs for 34 (MoSBAT similarity score &gt;0.5 and &gt;0.2, respectively). Thus, there is overall (albeit imperfect) agreement between the two studies. For the 242 proteins represented in at least one study, we selected a highest-confidence motif for each protein, utilizing several motif-derivation approaches, and evaluating motifs within and across data sets. Peaks for the majority (158) are enriched (96% with AUC &gt;0.6 predicting peak vs. nonpeak) for a motif that is supported by the C2H2 “recognition code,” consistent with intrinsic sequence specificity driving DNA binding in cells. An additional 63 yield motifs enriched in peaks, but not supported by the recognition code, which could reflect indirect binding. Altogether, these analyses validate both data sets, and provide a reference motif set with associated quality metrics.

Published: November 2017

Abstract

Objectives
The purpose of this work was to investigate the fitness of the existing truck seats for Bangladeshi truck drivers and suggest a guideline for drivers’ seats based on their anthropometry.

Methodology
In this study, eight anthropometric measurements of 120 Bangladeshi truck drivers and seven seat dimensions of ninety trucks of three brands namely, TATA, ASHOK LEYLAND, and ISUZU were considered for investigating the considerable mismatch between seat dimensions and drivers’ anthropometry. The data were analyzed using two-sample t-tests to identify the relationship between existing seat dimensions and drivers’ anthropometry.

Results
The results showed a mismatch in seat dimensions and anthropometric measurements for nearly all truck brands and the existing seat dimensions were found to be inappropriate for Bangladeshi drivers. For all the truck brands, the percentage mismatch of seat height, seat depth, seat width, backrest height, and steering wheel clearance varied between 71% and 98%, 23% and 79%, 33% and 84%, 28% and 65%, and 53% and 100% respectively. Subsequently, an attempt was made to provide ergonomically correct seat dimensions for Bangladeshi truck drivers. Further, generalized equations to design the appropriate seat dimensions were developed using the least square regression technique. The recommended seat height, depth and width, backrest height, and steering wheel clearance were found to be appropriate for 82%, 79%, 76%, 98%, and 100% of drivers respectively.

Conclusion
The analysis and results of this study can be useful in developing guidelines for design and manufacture of truck driver seats in Bangladesh.

Abstract

Objectives
The purposes of this study were to clarify 1) the prevalence of foot and ankle pain and 2) the factors associated with foot and ankle pain among nurses.

Methods
Nurses working at a university hospital in Japan were recruited to participate in this crosssectional, questionnaire-based study. The occurrence of foot and ankle pain in the previous month was assessed by using the Standardized Nordic Questionnaire and the Manchester Foot Pain and Disability Index. Subjects also answered questions on footwear-related factors, including using the visual analog scale for shoe comfort. In addition, information on personal factors and psychosocial factors was collected using the Job Content Questionnaire. The relationships between the presence of foot and ankle pain and the associated factors were examined using multiple logistic regression analysis.

Results
Responses of 636 nurses (response rate, 67%) were included for analysis. The prevalence of foot and ankle pain was 23% and 51% when using the Standardized Nordic Questionnaire and the Manchester Foot Pain and Disability Index, respectively. The prevalence of pain that prevented the nurses from performing activities of daily living and work was 4% and 17%, respectively. A low level of shoe comfort, personal factors (age and body mass index), and psychosocial factors (low job control and high job strain) was independently associated with the presence of foot and ankle pain.

Conclusions
Foot and ankle pain occurred frequently in nurses. Shoe comfort, personal factors, and psychosocial factors were associated with foot and ankle pain.

***Relationship between functional class and left ventricular ejection fraction in patients with coronary heart disease who were candidates for cardiac rehabilitation***AIMS: To assess the potential relation between the New York Heart Association functional class and left ventricular ejection fraction in coronary heart disease patients who were candidates for cardiac rehabilitation.METHODS: This is a retrospective cross-sectional study based on the analysis of medical records of coronary heart disease patients who were candidates for the Cardiac Rehabilitation Program of Hospital Universitário de Santa Maria, state of Rio Grande do Sul, Brazil. Both male and female patients aged 50 to 65 were included, whereas patients with chronic renal failure, anemia, poor echocardiographic image quality, non-sinus rhythm, and also those individuals whose medical records lacked sufficient information were excluded. Data were collected from August 2015 to March 2016, and the information that made up the variables of interest was extracted from the medical records, such as: clinical and demographic data (sex, age, comorbidities, clinical diagnosis, surgical and drug treatment), left ventricular ejection fraction values obtained by echocardiography (conventional and tissue Doppler echocardiography), and functional class from the ergometric test. Statistical analysis was performed using Kruskal-Wallis test followed by Dunn’s post-hoc test. The significance level was set at p<0.05.RESULTS: A total of 131 medical records were consecutively evaluated, of which 102 met the inclusion criteria. Mean age was 59.23±7.95 years and 70 (68.63%) patients were male, with a predominance of functional class I. There was an inverse relation between functional class and ejection fraction: the more advanced the functional class, the more compromised the cardiac performance (p=0.036).CONCLUSIONS: In this sample of patients with coronary heart disease who were candidates for cardiac rehabilitation, there was an inverse relation between left ventricular ejection fraction and functional class. This finding provides information about the limitations imposed by the disease on patient’s exercise capacity and heart function and can contribute to the development of a physical training program.

Published: November 2017

Purpose: To systematically review studies on cost-effectiveness of implementing Antimicrobial stewardship programmes (ASP) in the hospital setting. Methods: A systematic literature search was performed using electronic databases, such as EMBASE, PubMed/Medline, CINAHL, NHS and CEA Registry from 2000 until 2017. The quality of each included study was assessed using Joanna Briggs Institute Critical Appraisal Checklist for Economic Evaluations and Consolidated Health Economic Evaluation Reporting Standards Statement checklist. Results: Of the 313 papers retrieved, five papers were included in this review after assessment for eligibility. The majority of the studies were cost-effectiveness studies, comparing ASP to standard care. Four included economic studies were conducted from the provider (hospital) perspective while the other study was from payer (National Health System) perspective. The cost included for economic analysis were as following: personnel costs, warded cost, medical costs, procedure costs and other costs. Conclusions: All studies were generally well-conducted with relatively good quality of reporting. Implementing ASP in the hospital setting may be cost-effective. However, comprehensive cost-effectiveness data for ASP remain relatively scant, underlining the need for more prospective clinical and epidemiological studies to incorporate robust economic analyses into clinical decisions.

Whirl Simulation of Drill Collar and Estimation of Cumulative Fatigue Damage on Drill-Collar Connection
Authors: Zhao Dapeng , Hovda Sigve , Sangesland Sigbjørn 
Published: November 2017

Summary
Most drill-collar-connection failures are attributed to cumulative fatigue caused by bending vibration. An important class of bending vibration is whirl, which is formed by the eccentricity of the rotational drill collar. The contact between the drill collar and the borehole causes extreme harmful backward whirl, even chaotic whirl. A two-degree-of-freedom nonlinear lumped-mass model is used to represent the drill collar in whirl. Unlike other studies, the stick/slip vibration causing fluctuation of rotary speed is taken into account. In this lumped-element model, the contact forces obey the Hertzian contact law, which leads to lateral bounce of the drill collar and affects the borehole wall chaotically. The modified Karnopp friction model is adopted to simulate the stick/slip rotary vibration of the bottomhole assembly (BHA). On the basis of the time-domain responses of whirl, the continuous-bending-stress history is broken down into individual stress ranges with an associated number of stress cycles using the rainflow-counting method. The cumulative fatigue damage is estimated using Miner's rule. The conclusion of this paper indicates that chaotic lateral vibration and fatigue damage happen at a lower rotational speed than previously reported.
Human excreta: a resource or a taboo? Assessing the socio-cultural barriers, acceptability, and reuse of human excreta as a resource in Kakul Village District Abbottabad, Northwestern Pakistan
Authors: Khalid Abda 
Published: November 2017

Abstract
Sustainable reuse of human excreta in socially and religiously conservative societies is extremely difficult. People's perceptions and acceptability regarding the reuse of human excreta is mainly linked to their culture. In addition, certain societies regard the cultural and social barriers more than the religious barriers. The aim of this study is to understand the perceptions of people about the reuse of human excreta for agricultural purposes. Qualitative research methods were used for data collection. Farmers in the village recognized the importance and economic benefit of reusing human excreta. They accepted the reuse of human excreta on their farms only if they were supplied with a treatment facility. Contrary to the farmers, the local community showed reluctance in reusing human excreta while recognizing the nutritional value of it. It was therefore concluded that the main barrier in sustainable and safe re-use of human excreta lies in socio-cultural and religious foundations of traditional societies like Kakul village in Abbottabad District.

Authors: Kitsai Juliana Anatolyevna 
Published: November 2017

According to the author, changes in higher education are focused on the implementation of the concept of entrepreneurial university. This concept involves the changes of the basic approaches to both the organization of internal activities of higher education institutions and to interaction with other actors (the state, regional authorities, business, foreign partners). The concept of an entrepreneurial university (University 3.0.) is associated with a general reform of the social sphere, oriented toward the process of its denationalization.

Published: November 2017

Background:A number of previous studies have concluded that long-term unemployment is destructive to health.Objective:This study examined health behavior and self-assessed health of some long-term unemployed persons living in the city of Turku, in Southwestern Finland.Methodology:The qualitative data were collected from February to March 2016 from 40 long-term unemployed men and women, aged between 31 to 63 years.Results:Of the participants 85% (n=34) reported that their long-term unemployment situation had had a negative impact on their health. There were 95% (n=36) who needed medical care because of their health condition. There were 59% (n=24) who were not satisfied with the healthcare and social services compared to 49% (n=16) who were satisfied with the services.Conclusion:There were more single men than single women among the participants. Half of the participants had a profession of which the women constituted the majority. Several participants were suffering from a chronic disease. The participants were not satisfied of their lives and attributed their health behavior and poor health conditions to their long-term unemployment situation. They were not satisfied also with the healthcare and social services provided to them.

Authors: Meiszterics Zsófia , Kónyi Attila , Hild Gábor , Sárszegi Zsolt , Gaszner Balázs 
Published: November 2017

Aim & methods:
This 6-month prospective, observational, noninterventional, open-label clinical study assessed the effectiveness/safety of trimetazidine in 737 patients with stable angina pectoris and Type 2 diabetes mellitus (OGYI/51534–1/2014).
Results:
Trimetazidine-based therapy was effective in stable coronary artery disease, with significant improvements from baseline (p < 0.05) in: number of angina attacks/week (2.9 ± 2.4 vs 1.1 ± 1.6), angina severity (Canadian Cardiovascular Society Classification 1.9 ± 0.8 vs 1.2 ± 0.8), exercise capacity (metabolic equivalents 6.1 ± 1.7 vs 6.5 ± 1.7), and exercise-induced myocardial ischemia (min 5.5 ± 2.5 vs 6.5 ± 2.6).
Discussion:
Trimetazidine treatment significantly (p < 0.05) improved glucose metabolism, lowered HbA1c (7.1 ± 1.1% vs 6.6 ± 1.0%), glucose levels (7.7 ± 2.1 mmol/l vs 6.9 ± 1.6 mmol/l) and decreased arterial stiffness (pulse wave velocity 11.2 ± 2.1 m/s vs 10.4 ± 2.2 m/s). In most patients, the tolerability of trimetazidine was rated as excellent to good, with a low incidence of adverse events.
Perbandingan Kinerja Reservoir Gas Konvensional dengan Coal Bed Methane (CBM)
Authors: Suranto Ahmad Muraji 
Published: November 2017

Reservoir gas konvensional yang dikenal oleh masyarakat luas adalah reservoir yang terdiri dari jebakan reservoir (cap rock), batuan reservoir dan isi (gas). Sedangkan perangkapnya bisa berupa perangkap struktur, stratigtafi, patahan atau kombinasi dari ketiganya. Sedangkan reservoir yang menghasilkan gas methane batubara (Coal Bed Methane yang disingkat CBM) merupakan zona batubara yang terisolasi, memiliki rekah alam dan terisi oleh air. pada kondisi awal kedua tipe reservoir ini (reservoir gas konvensional dan CBM) mempunyai karakteristik yang berbeda, sehingga teknik perhitungan cadangan, cara memproduksikan dan kinerjanya akan berbeda pula. Karena mempunyai latarbelakang yang berbeda maka kiranya perlu dilihat kinerjanya seberapa jauh perbedaannya karena keduanya memproduksikan gas hidrokarbon.

Untuk melihat kinerja reservoirnya baik reservoir gas konvensional atau CBM maka dalam kajian ini menggunakan simulator. Dari kedua model, volume masing-masing reservoir dibuat sama, dan dilakukan sensitivitas karakteristik reservoirnya terhadap masing-masing model. Hasil akhir yang dibandingkan adalah kinerja dari masing-masing reservoir tersebut.

Hasil yang didapat dari kajian ini adalah bahwa reservoir CBM mempunyai laju produksi gas lebih rendah, daerah pengurasan lebih kecil dan recovery factor lebih sedikit bila dibandingkan dengan reservoir gas konvensional. Tetapi karena cadangan gas konvensional semakin lama semakin menipis, maka reservoir CBM sebagai alternatif yang perlu dikembangkan setelah gas konvensional. Kebijakan pajak pemerintah sangat penting untuk kelangsungan produksi CBM.

SUMMARYObjective:The purpose of this study was to determine the fracture strength of endodontically treated mandibular premolar teeth restored with composites and different reinforcement techniques.Methods and Materials:Forty-eight freshly extracted human mandibular premolar teeth were randomly divided into four groups: group IN, group CR, group FRC, and group PRF. Group IN consisted of teeth with intact crowns and served as the control group. In the other three groups, endodontic treatment was performed and standard mesio-occluso-distal (MOD) cavities were prepared. Then cavities were restored with hybrid resin composite only, flowable composite and hybrid resin composite, and Ribbond, flowable composite and hybrid resin composite in groups CR, FRC and PRF, respectively. All of the teeth were subjected to fracture by means of a universal testing machine, and compressive force was applied with a modified stainless-steel ball at a crosshead speed at 0.5 mm/min.Results:The highest values were observed in group IN, while the lowest values were determined in group CR. There was not any statistically significant difference between group CR and group FCR (p&gt;0.05). When groups CR, FCR, and PRF were compared, group PRF showed significantly better fracture strength than did groups CR and FCR (p&lt;0.05). It was determined that there was not any significant difference between group IN and group PRF (p&gt;0.05).Conclusions:Polyethylene ribbon fiber considerably increases the fracture strength of mandibular premolar teeth with MOD cavities restored with composite.
