Effect of replacing nanofluid instead of water on heat transfer in a channel with extended surfaces under a magnetic field
Authors: Aghakhani Saeed , Ghasemi Behzad , Hajatzadeh Pordanjani Ahmad , Wongwises Somchai , Afrand Masoud 
Published: May 2019

Purpose
The purpose of this study is to conduct a numerical analysis of flow and heat transfer of water–aluminum oxide nanofluid in a channel with extended surfaces in the presence of a constant magnetic field. The channel consists of two parallel plates and five obstacles of constant temperature on the lower wall of the channel. The upper wall and the inlet and outlet lengths of the lower wall are insulated. A uniform magnetic field of the magnitude B0 is located beneath the obstacles. The nanofluid enters the channel with a uniform velocity and temperature, and a fully developed flow leaves the channel.

Design/methodology/approach
The control volume-based finite difference and the SIMPLE algorithm were used for numerical solution. In addition to examining the effect of the Reynolds number, the effects of Hartman number, the volume fraction of nanoparticles, the height of obstacles, the length of obstacles and the distance between the obstacles were investigated.

Findings
According to the results, the heat transfer rate increases with an increasing Reynolds number. As the Hartmann number increases, the heat transfer rate increases. The heat transfer rate also increases with an increase in the volume fraction of nanoparticles. The mean Nusselt number is reduced by an increasing height of obstacles. An increase in the distance between the obstacles in the presence of a magnetic field does not have a significant impact on the heat transfer rate. However, the heat transfer rate increases in the absence of a magnetic field, as the distance between the obstacles increases.

Originality/value
This paper is original and unpublished and is not being considered for publication elsewhere.
An adaptive inner iterative pressure-based algorithm for steady and unsteady incompressible flows
Authors: Wang Jin-Ping , Zhang Jian-Fei , Qu Zhi-Guo , Tao Wen-Quan 
Published: May 2019

Purpose
Pressure-based methods have been demonstrated to be powerful for solving many practical problems in engineering. In many pressure-based methods, inner iterative processes are proposed to get efficient solutions. However, the number of inner iterations is set empirically and kept fixed during the whole computation for different problems, which is overestimated in some computations but underestimated in other computations. This paper aims to develop an algorithm with adaptive inner iteration processes for steady and unsteady incompressible flows.

Design/methodology/approach
In this work, with the use of two different criteria in two inner iterative processes, a mechanism is proposed to control inner iteration processes to make the number of inner iterations vary during computing according to different problems. By doing so, adaptive inner iteration processes can be achieved.

Findings
The adaptive inner iterative algorithm is verified to be valid by solving classic steady and unsteady incompressible problems. Results show that the adaptive inner iteration algorithm works more efficient than the fixed inner iteration one.

Originality/value
The algorithm with adaptive inner iteration processes is first proposed in this paper. As the mechanism for controlling inner iteration processes is based on physical meaning and the feature of iterative calculations, it can be used in any methods where there exist inner iteration processes. It is not limited for incompressible flows. The performance of the adaptive inner iteration processes in compressible flows is conducted in a further study.
Patrons’ behaviours towards Malaysian slimming centres: paradigm of marketing mixes
Authors: Hassan Hasliza , Sade Abu Bakar , Rahman Muhammad Sabbir 
Published: May 2019

PurposeSlimming centres have become a hot spot for people to reduce their size and reshape their body figure through the sophisticated and modern treatments that are provided by the therapists. The purpose of this paper is to examine the influence of price, place and promotion on the behavioural intention to consume the slimming treatments.Design/methodology/approachThis research is a cross-sectional study in which 308 primary data were collected for descriptive analysis, confirmatory factor analysis and structural equation modelling. The data were collected through a survey questionnaire that was distributed to respondents who have experience in consuming slimming treatment at a slimming centre.FindingsThe majority of slimming centre consumers are working women aged 25 and above from urban areas. As an attraction, the pricing strategy is a very important influence on consumers to consume the slimming treatment at slimming centres. Although the main target market for slimming centres is career women who are earning an above average income, an excessively high price might weaken the behavioural intention of the consumer to consume the service since Malaysian women are very price conscious. The findings also indicate that there is a significant correlation relationship between price and promotion as well as place and promotion.Originality/valueThis research is expected to contribute in terms of providing more knowledge about this industry, since there are still limited findings pertaining to slimming centres, especially in the Malaysian market.
Data-based decision making in primary schools in Ethiopia
Authors: Yibrie Ahmed Ahmed 
Published: May 2019

PurposeThe Ethiopian educational system has witnessed considerable structural and curricular changes aimed to address access, equity and relevance. At the same time, there are serious concerns about educational quality as a consequence of these changes. Data use can be an important approach for changing the planning, execution, monitoring and evaluation of activities having the purpose of improving teaching and learning. The purpose of this paper is, therefore, to investigate data use in primary education in Ethiopia.Design/methodology/approachUsing a mixed methods approach, surveys and semi-structured interviews were conducted to collect data from a cluster random sample of eight primary schools representing four different levels of effectiveness in implementing a mandated school improvement program in Ethiopia.FindingsThe availability of wider ranges of input, process, outcome and context dataper sedoes not ensure actual use. A complex combination of data, user and organizational factors influences data use in schools, with organizational factors appearing to be most influential. Unrealistic accountability pressures and lack of targeted supervision support seemed to cause unintended data use, such as abuse of data.Practical implicationsSchools need more systematic professional development in data use, with explicit attention to school leadership. Moreover, it is important to make educational inspection processes more responsive to the demands of the school improvement process by adding aspects of the school improvement tradition, such as data-based decision making.Originality/valueThis study contributes to understanding of the nature, characteristics and processes of data use in a developing country context, in which competing accountability mandates often shape policy and practice.

ObjectiveTo investigate the burden of maternal near‐miss and death due to rupture of the gravid uterus, the indicators of quality of care, and avoidable factors associated with care deficiencies for ruptured uterus in Nigerian tertiary hospitals.DesignSecondary analysis of a nationwide cross‐sectional study.SettingForty‐two tertiary hospitals.PopulationWomen admitted for pregnancy, childbirth or puerperal complications.MethodsCases of severe maternal outcome [SMO: maternal near‐miss (MNM) or maternal death (MD)] following uterine rupture were prospectively identified over 1 year.Main outcome measuresIncidence of SMO, indicators of quality of care, and avoidable factors associated with deficiencies in care.ResultsThere were 91 724 live births and 3285 women with SMO during the study period. SMO due to uterine rupture occurred in 392 women: 305 MNM and 87 MD. Uterine rupture accounted for 11.9, 13.3, and 8.7% of all SMO, MNM, and MD, respectively. SMO, MNM, and intra‐hospital maternal mortality ratios due to uterine rupture were 4.3/1000 live births, 3.3/1000 live births, and 94.8/100 000 live births, respectively. Mortality index (% of MD/SMO) was 22.2%, and MNM:MD ratio was 3.5. Avoidable factors contributing to deaths were related to patient‐orientated problems, especially late hospital presentation and lack of insurance to cover life‐saving interventions. Medical personnel problems contributed to care deficiencies in one‐third of women who died.ConclusionUterine rupture significantly contributes to SMO in Nigerian tertiary hospitals. Strategies to improve maternal survival should address avoidable institutional factors and include community‐based interventions to encourage skilled attendance at birth and early referral of complications.Tweetable abstractUterine rupture remains an important cause of maternal death in Nigerian tertiary hospitals.
Two cases with autoantibodies to small ubiquitin‐like modifier activating enzyme: A potential unique subset of dermatomyositis‐associated interstitial lung disease

Published: May 2019

AbstractThe presence of anti‐aminoacyl tRNA synthetase (ARS) or anti‐melanoma differential‐associated gene 5 (MDA5) is strongly related to interstitial lung disease (ILD) in patients with dermatomyositis (DM). Several studies suggest a potential relationship between ILD and anti‐small ubiquitin‐like modifier activating enzyme (SAE) antibody in DM patients, but detailed clinical characteristics of anti‐SAE‐associated ILD still remain unknown. We have experienced 2 cases who were positive for anti‐SAE antibody, who presented with ILD in the context of clinically amyopathic DM. These 2 patients had the following common ILD characteristics: an insidious course with preserved pulmonary function; a limited extent of pulmonary lesions with subpleural peripheral‐dominant small ground glass opacity/consolidation on high‐resolution computed tomography; and a favorable treatment response. These findings suggest that anti‐SAE‐associated ILD is unique in terms of clinical and imaging features and differs from ILD associated with anti‐ARS or anti‐MDA5 antibody.

AbstractObjectivesBased on Andersen's healthcare utilization model, the present study examined factors associated with dental service use in older Korean Americans. Focus was on predisposing characteristics (age, gender, marital status, education and region), oral health needs (problems with teeth or gums and self‐rated oral health) and enabling factors (dental health insurance, length of stay in the United States, acculturation and family network).MethodsUsing data from surveys with Korean Americans aged 60 or older (N = 2128), a Poisson regression model examined predictors of dental visit in the past 12 months.FindingsMore than 21% of the sample reported having a problem with teeth or gums, and over half rated their oral health as either fair or poor. Approximately 71% lacked dental health insurance. The number of dental visits in the past 12 months averaged 1.40 (SD = 1.74), with about 38% having no dental visits at all. Multivariate analyses showed that higher levels of education, the presence of a problem with teeth or gums, dental health insurance coverage, longer length of stay in the United States, and larger family networks were associated with 1.01‐1.35 times higher number of dental visits.ConclusionThe findings not only confirmed the critical role of dental health insurance as a service enabler but also highlighted the importance of considering older ethnic immigrants’ oral health and dental care from the perspectives of culture and family.

Published: May 2019

AbstractAimTo examine the distribution and association of sociodemographic, adherence, and barriers‐to‐care factors in relation to glycaemic control within insulin regimens in US children with Type 1 diabetes in the SEARCH for Diabetes in Youth Study.MethodsSelf‐ or parent‐reported data from 1095 children with Type 1 diabetes aged 10–17 years were collected on insulin regimen, sociodemographics, diabetes self‐management, diabetes‐related family conflict and barriers to care. Multivariable logistic regression analysis identified poor glycaemic control correlates within each insulin regimen.ResultsParticipants included 694 children on insulin pump therapy, 188 receiving basal–bolus injections, and 213 on a mixed insulin regimen. Of these, 28.5%, 45.2% and 51.2%, respectively, had poor glycaemic control [HbA1c ≥ 80 mmol/mol (9.5%)]. Family conflict between parent and child regarding diabetes management was the only factor significantly associated with poor glycaemic control in all insulin regimens (insulin pump, P≤ 0.0001; basal–bolus injections, P=0.0002; mixed insulin regimen, P=0.0103). For children on insulin pump, poor control was significantly associated with non‐white race (P=0.0008), living in multiple households (P=0.0331), having Medicaid insurance (P=0.0090), and decreased insulin adherence (P<0.0001). For children on a mixed insulin regimen, living in multiple households (P=0.0256) and not spending enough time with healthcare provider (P=0.0058) correlated with poor control.ConclusionsA high percentage of US children with Type 1 diabetes had poor glycaemic control, especially those not using an insulin pump. Early identification of children with risk factors associated with poor glycaemic control within insulin regimens and addressing diabetes‐related family conflict may allow interventions to improve diabetes management.
Evidence and potential mechanisms of traditional Chinese medicine for the treatment of type 2 diabetes: A systematic review and meta‐analysis

Published: May 2019

AbstractTraditional Chinese medicine (TCM) has recorded knowledge of diabetes for over 2000 years. Because a considerable number of TCM studies exhibit design defects, such as limited intervention duration, small sample sizes and inconsistent efficacy evaluations, the role of TCM in the treatment of diabetes cannot be fully elucidated. In this review, we evaluate randomized controlled trials of prediabetes, diabetes and diabetic complications published in the past decade. We found that TCM could significantly improve glucose control and clinical indices in patients with diabetes and effectively delay the progression of diabetes. We also summarize potential pharmacological mechanisms underlying the efficacy of TCM medication/herbs and their active ingredients for treating diabetes. More rigorously designed experiments and long‐term evaluation of TCM for diabetes will allow for more effective diabetes management.
Manual fish length measurement accuracy for adult river fish using an acoustic camera (DIDSON)

Published: May 2019

AbstractTotal lengths (LT) of 50 free‐swimming fish in a tank, silver carp Hypophthalmichthys molitrix and rainbow trout Oncorhynchus mykiss, were measured using a DIDSON (Dual‐frequency IDentification SONar) camera. Using Sound Metrics software, multiple measurements of each fish (LT, side aspect angle and distance from the camera) at different times were analysed by two experienced operators while a subset of data was analysed by two inexperienced operators. The main result showed high variability in intra‐fish LT measurements. The number of measurements required to minimise errors and to obtain robust fish measurements (true LT ± 3 cm) was estimated by a bootstrap method. Three to five measurements per fish were recommended for fish surveys in rivers. In this experimental study, aiming to reproduce river conditions, no evidence of fish position (side aspect angle and distance from the camera) effect was detected, but an operator effect (partially explained by training) was observed. General linear mixed models also showed that lengths of the smallest fish (LT < 57 cm) were overestimated and lengths of the largest fish (LT > 57 cm) were underestimated in comparison with their true lengths. In conclusion, we highlight that this technology, like any monitoring methods, returns imperfect observations. We advise DIDSON users to ensure that measurements are carried out correctly in order to draw accurate conclusion from this new technology.
An overview of active and passive targeting strategies to improve the nanocarriers efficiency to tumour sites
Authors: Attia Mohamed F , Anton Nicolas , Wallyn Justine , Omran Ziad , Vandamme Thierry F 
Published: May 2019

Abstract

Objectives
This review highlights both the physicochemical characteristics of the nanocarriers (NCs) and the physiological features of tumour microenvironment (TME) to outline what strategies undertaken to deliver the molecules of interest specifically to certain lesions. This review discusses these properties describing the convenient choice between passive and active targeting mechanisms with details, illustrated with examples of targeting agents up to preclinical research or clinical advances.

Key findings
Targeted delivery approaches for anticancers have shown a steep rise over the past few decades. Though many successful preclinical trials, only few passive targeted nanocarriers are approved for clinical use and none of the active targeted nanoparticles. Herein, we review the principles and for both processes and the correlation with the tumour microenvironment. We also focus on the limitation and advantages of each systems regarding laboratory and industrial scale.

Summary
The current literature discusses how the NCs and the enhanced permeation and retention effect impact the passive targeting. Whereas the active targeting relies on the ligand-receptor binding, which improves selective accumulation to targeted sites and thus discriminates between the diseased and healthy tissues. The latter could be achieved by targeting the endothelial cells, tumour cells, the acidic environment of cancers and nucleus.
