Numerical simulation for magnetohydrodynamic three dimensional flow of Casson nanofluid with convective boundary conditions and thermal radiation
Authors: Gupta Sumit , Sharma Kalpna 
Published: September 2017

Purpose
The purpose of this study is to analyze magnetohydrodynamic three-dimensional flow of Casson nanofluid over a stretching sheet in presence of thermophoresis and Brownian motion effects. In contrast, the convective surface boundary conditions with the effects of radiation are applied.

Design/methodology/approach
The governing partial differential equations are transformed into highly nonlinear coupled ordinary differential equations consisting of the momentum, energy and nanoparticle concentration via suitable similarity transformations, which are then solved the using optimal homotopy analysis method (OHAM) a Mathematica Package BVPh2.0.

Findings
The influence of emerging physical flow parameters on fluid velocity component, temperature distribution and nanoparticle concentration are discussed in detail. Also, an OHAM solution demonstrates very good correlation with those obtained in the previously published results. It is noticed that OHAM can overcome the earlier restriction, assumptions and limitation of traditional perturbation method. The main advantage of this method is that OHAM can be applied directly to nonlinear differential equations without using linearization and round-off errors, and therefore, it cannot be affected by error associated to discretization.

Originality/value
Here the approximate solutions are compared with the numerical results published in earlier work.
The comparison of two reliable methods for the accurate solution of fractional Fisher type equation
Authors: Saha Ray S. 
Published: September 2017

Purpose
The purpose of this paper is the comparative analysis of Haar Wavelet Method and Optimal Homotopy Asymptotic Method for fractional Fisher type equation. In this paper, two reliable techniques, Haar wavelet method and optimal homotopy asymptotic method (OHAM), have been presented. The Haar wavelet method is an efficient numerical method for the numerical solution of fractional order partial differential equation like the Fisher type. The approximate solutions of the fractional Fisher-type equation are compared with those of OHAM and with the exact solutions. Comparisons between the obtained solutions with the exact solutions exhibit that both the featured methods are effective and efficient in solving nonlinear problems. However, the results indicate that OHAM provides more accurate value than the Haar wavelet method.

Design/methodology/approach
Comparisons between the solutions obtained by the Haar wavelet method and OHAM with the exact solutions exhibit that both featured methods are effective and efficient in solving nonlinear problems.

Findings
The comparative results indicate that OHAM provides a more accurate value than the Haar wavelet method.

Originality/value
In this paper, two reliable techniques, the Haar wavelet method and OHAM, have been proposed for solving nonlinear fractional partial differential equation, i.e. fractional Fisher-type equation. The proposed novel methods are well suited for only nonlinear fractional partial differential equations. It also exhibits that the proposed method is a very efficient and powerful technique in finding the solutions for the nonlinear time fractional differential equations. The main significance of the proposed method is that it requires less amount of computational overhead in comparison to other numerical and analytical approximate methods. The application of the proposed methods for the solutions of time fractional Fisher-type equations satisfactorily justifies its simplicity and efficiency.

Authors: Tapaswini Smita , Mu Chunlai , Behera Diptiranjan , Chakraverty Snehashish 
Published: September 2017

Purpose
Vibration of large membranes has great utility in engineering application such as in important parts of drums, pumps, microphones, telephones and other devices. So, to obtain a numerical solution of this type of problems is necessary and important. In general, in existing approaches, involved parameters and variables are defined exactly. Whereas in actual practice, it may contain uncertainty owing to error in observations, maintenance-induced error, etc. So, the main purpose of this paper is to solve this important problem numerically under fuzzy and interval uncertainty to have an uncertain solution and to study its behaviour.

Design/methodology/approach
In this study, the authors have considered a new approach is known as double parametric form of fuzzy number to model uncertain parameters. Along with this a semianalytical approach, i.e. variational iteration method, has been used to obtain uncertain bounds of the solution.

Findings
The variational iteration method has been successfully implemented along with the double parametric form of fuzzy number to find the uncertain solution of the vibration equation of a large membrane. The advantage of this approach is that the solution can be written in a power series or a compact form. Also, this method converges rapidly to obtain an accurate solution. Various cases depending on the functional value involved in the initial conditions have been studied and the behaviour has been analysed. Applying the double parametric form reduces the computational cost without separating the fuzzy equation into coupled differential equations as done in traditional approaches.

Originality/value
The vibration equation of large membranes has been solved under fuzzy and interval uncertainty. Uncertainties have been considered in the initial conditions. New approaches, i.e. variational iteration method along with the double parametric form, have been applied to solve the vibration equation of large membranes.

Authors: Khan Umar , Abbasi Adnan , Ahmed Naveed , Mohyud-Din Syed Tauseef 
Published: September 2017

Purpose
The purpose of this paper is to explore the impact of thermal radiation, viscous dissipation and Joule heating effects on the flow of a magneto-nanofluid between two horizontally placed plates. Three distinct shapes of nanoparticles in a base fluid (water) are considered to compose the nanofluid.

Design/methodology/approach
Introducing feasible similarity variables, the flow model is transformed into a nonlinear and coupled system of ordinary differential equations. The consequent system is solved by using homotopy analysis method.

Findings
Furthermore, the influence of embedded parameters on velocity and temperature profiles is highlighted graphically. The same is done for showing the variations in skin friction coefficient and local rate of heat transfer. Under certain conditions, present results compared with already existing results in the literature. Some main findings are pinpointed in the last section before the bibliography. From presented work, it is analyzed that the velocity field along y-axis and x-axis are increasing and decreasing functions of suction/injection parameter. The velocity of the fluid starts increases for Reynolds number and declines for volumetric fraction of the nanoparticles. Significant variations in angular velocity are observed for volumetric fraction and Reynolds number, respectively. Thermal field increases rapidly for brick-shaped nanoparticles, and for platelet-shaped nanoparticles, it decreases rapidly. Local rate of heat transfer increases for radiation and Reynolds number and starts decreasing for Eckert number.

Originality/value
The study presented is original and has not been submitted to any other journal for the publication purpose. The contents are original and proper references have been provided wherever applicable.

Authors: K. Venkatadri , S. Gouse Mohiddin , M. Suryanarayana Reddy 
Published: September 2017

Purpose
This paper aims to focus on linear and non-linear convection in a lid-driven square cavity with isothermal and non-isothermal bottom surface.

Design/methodology/approach
It is assumed that the top moving wall is adiabatic and the bottom wall is heated in two modes, and the rest of the walls are maintained at uniform cold temperature. The coupled governing non-linear partial differential equations are solved numerically with MAC algorithm for conducting a parametric study with uniform and non-uniform temperature bottom wall.

Findings
The numerical results are depicted in the form of streamlines, temperature contours and variation of local Nusselt number. The local Nusselt number at the bottom wall of the cavity increases in presence of non-linear temperature parameter as compared with linear temperature parameter and heat transfer reduces with increasing of Ha for uniform and non-uniform heating of bottom wall.

Research limitations/implications
The numerical investigation is conducted for unsteady, two-dimensional natural convective flow in a square cavity. An extension of the present study with the effect of inclination of cavity, wavy walls and triangular cavity will be the interest of future work.

Originality/value
This work studies the effect of magnetic field in the presence of linear convection and non-linear convection. This study might be useful to cooling of electronic components, alloy casting, crystal growth and fusion reactors, etc.
Evaluating planting date and variety management strategies for adapting winter wheat to climate change impacts in arid regions
Authors: Hesam Arefi Iman , Saffari Mehri , Moradi Rooholla 
Published: September 2017

PurposeThe purpose of this study is to simulate the climate change impacts on winter wheat production and evaluate the possibilities of using various varieties and shifting planting date as two climate change adaptation strategies in Kerman Province, Iran.Design/methodology/approachTwo types of global circulation model and three scenarios for three periods were used. Daily climatic parameters were generated by LARS-WG (Long Ashton Research Station-Weather Generator). The CERES-wheat model was used to simulate future winter wheat growth, development and production.FindingsThe results showed that CO2had no effect on the phenology of winter wheat, and the negative impact of temperature on the grain yield was higher than the positive effect of CO2enrichment. The length of the reproductive growth period of the winter wheat was significantly shortened as affected by the negative impacts of rise in temperature. The simulated results indicated that the grain yield of common (medium maturing) variety of winter wheat will decline, ranging from −0.27 to −18.71 per cent according to future climate changes. Adaptation strategies showed that the early maturing variety had a higher and more stable grain yield under climate change conditions than medium and delayed maturing varieties. Earlier planting date (20 October) increased wheat grain yield under future climatic conditions than common (November 5) planting date. In reverse, later planting (November 20) would accelerate harmful effects of climate change on wheat grain yield.Originality/valueThe results highlighted the potential of early maturing variety and early planting date as the appropriate agronomical approaches for mitigating harmful impacts of climate change on winter wheat production in arid regions.
Evaluating the environmental and economic impacts of one China’s HDR geothermal energy based heating system in a life cycle framework
Authors: LIU Hongtao 
Published: September 2017

Purpose
In recent years, fast urban expansion in China has stimulated rapid energy consumption growth and increased environmental pollution. Therefore, it is important to utilize clean and renewable energy in district heating for the sustainable urban development. This study aimed to investigate the environmental and economic impacts of one hot dry rock (HDR) geothermal energy-based heating system in a life cycle framework.

Design/methodology/approach
By using the input–output-based life cycle analysis model, the energy consumption, CO2 emission and other pollutants of the HDR-based heating system were evaluated and then compared with those of other four heating systems based on burning coal or natural gas. The life cycle costs of the HDR-based heating system were also analyzed.

Findings
The results showed that using HDR geothermal energy for heating can significantly reduce fossil fuel consumption, CO2 emission as well as environmental pollution, and its life cycle costs are also competitive.

Originality/value
This study not only evaluated the environmental and economic impacts of the HDR-based heating system in a life cycle framework but also provided a methodological life cycle assessment framework that can estimate both economic and environmental benefits, which can be used in policy making for China’s urban development.
Child and adolescent mental health services: longitudinal data sheds light on current policy for psychological interventions in the community
Authors: Neufeld Sharon A.S. , Jones Peter B. , Goodyer Ian M. 
Published: September 2017

Purpose
The purpose of this paper is to expand upon policy implications of a recent study assessing adolescent mental health service contact and subsequent depression.

Design/methodology/approach
Review of related evidence from academic and grey literature.

Findings
Studies assessing the role of mental health services in reducing mental disorder during adolescence are sparse, and even prevalence figures for adolescent mental disorders are out-of-date. Adolescent mental health service contact rates are shown to fall concurrent with budgetary decreases. School-based counselling is highlighted as an important source of help that may be at risk of being cut. Increased training of General Practitioners and school counsellors is needed to improve efficiency in specialist Child and Adolescent Mental Health Services (CAMHS).

Practical implications
Longitudinal studies of young people’s mental health should include mental health service usage and its relationship with subsequent mental health outcomes.

Social implications
Funding cuts to CAMHS must be avoided, school-based counselling must be protected, and service referrers should be better trained.

Originality/value
This paper highlights the need for increased CAMHS data, sustained funding, and improved training for this vital service.
Identification and characterization of a brilliant yellow pigment produced by Bordetella pertussis
Authors: Odanaka Keita , Iwatsuki Masato , Satho Tomomitsu , Watanabe Mineo 
Published: September 2017

ABSTRACTCulture supernatants of Bordetella pertussis are a brilliant yellow; however, the structure and biological role of the responsible pigment have not been investigated. In this study, a brilliant yellow‐colored fraction was extracted from culture supernatants of B. pertussis and analyzed by HPLC. UV–visible spectral analysis and mass spectrometry identified the brilliant yellow pigment as riboflavin. Riboflavin production was high in lag and early log phases and riboflavin was found to enhance growth of B. pertussis in low‐density cultures. Riboflavin production is not regulated by the BvgAS system. In addition, it was found that other Bordetella species, such as B. parapertussis, B. holmesii and B. bronchiseptica, also release riboflavin into their culture supernatants. This is the first report that B. pertussis secrets riboflavin to the extracellular space and that riboflavin may promote its growth. The mechanism may be associated with pathogenesis of B. pertussis.

Authors: Laudicella Mauro , Martin Stephen , Li Donni Paolo , Smith Peter C. 
Published: September 2017

ObjectivesTo measure the impact of the improvement in hospital survival rates on patients’ subsequent utilization of unplanned (emergency) admissions.Data Sources/Study SettingUnplanned admissions occurring in all acute hospitals of the National Health Service in England between 2000 and 2009, including 286,027 hip fractures, 375,880 AMI, 387,761 strokes, and 9,966,246 any cause admissions.Study DesignPopulation‐based retrospective cohort study. Unplanned admissions experienced by patients within 28 days, 1 year, and 2 years of discharge from the index admission are modeled as a function of hospital risk‐adjusted survival rates using patient‐level probit and negative binomial models. Identification is also supported by an instrumental variable approach and placebo test.Principal FindingsThe improvement in hospital survival rates that occurred between 2000 and 2009 explains 37.3 percent of the total increment in unplanned admissions observed over the same period. One extra patient surviving increases the expected number of subsequent admissions occurring within 1 year from discharge by 1.9 admissions for every 100 index admissions (0.019 per admission, 95% CI, 0.016–0.022). Similar results in hip fracture (0.006[0.004–0.007]), AMI (0.006[0.04–0.007]), and stroke (0.004(0.003–0.005)).ConclusionsThe success of hospitals in improving survival from unplanned admissions can be an important contributory factor to the increase in subsequent admissions.

AimThe present study aimed to describe referral patterns of general practitioner (GP) registrars to dietitians/nutritionists. There is a paucity of research regarding GP referral patterns to dietitians/nutritionists. Limited data show increasing referrals from established GPs to dietitians/nutritionists. There are no data on GP registrar (trainee) referrals.MethodsThis was a cross‐sectional analysis of data from the Registrar Clinical Encounters in Training (ReCEnT) study. ReCEnT is an ongoing, multicentre, prospective cohort study of registrars, which documents 60 consecutive consultations of each registrar in each of the three six‐month GP training terms. The outcome factor in this analysis was a problem/diagnosis resulting in dietitian/nutritionist referral (2010–2015). Independent variables were related to registrar, patient, practice and consultation.ResultsA total of 1124 registrars contributed data from 145 708 consultations. Of 227 190 problems/diagnoses, 587 (0.26% (confidence interval: 0.23–0.29)) resulted in dietitian/nutritionist referral. The most common problems/diagnoses referred related to overweight/obesity (27.1%) and type 2 diabetes (21.1%). Of referrals to a dietitian/nutritionist, 60.8% were for a chronic disease, and 38.8% were related to a Chronic Disease Management plan. Dietitian/nutritionist referral was significantly associated with a number of independent variables reflecting continuity of care, patient complexity, chronic disease, health equity and registrar engagement.ConclusionsEstablished patients with chronic disease and complex care needs are more likely than other patients to be referred by registrars to dietitians/nutritionists. Nutrition behaviours are a major risk factor in chronic disease, and we have found evidence for dietitian/nutritionist referrals representing one facet of engagement by registrars with patients’ complex care needs.

Published: September 2017

AbstractThree new Chinese yam polysaccharides (namely HSY, huaishanyao in Chinese) were isolated using the methods of boiled water extraction and stepwise ethanolic precipitation, combined with the tangential flow ultrafiltration membrane system. Their molecular weights were determined by high performance gel permeation chromatography. Three type yam polysaccharides in different molecular weight were isolated: HSY‐I (>50 kDa), HSY‐II (10 to 50 kDa), HSY‐III (<10 kDa). The monosaccharide and glycosidic bond links composition were analyzed with GC and Smith degradation. The structure characteristics were further discussed combined with infrared spectrophotometry. Dexamethasone‐induced insulin resistance glucose/lipid metabolism diabetic mice model was established to evaluate the hypoglycemic effect of different concentration of HSY and different molecular weights polysaccharide HSY‐I, HSY‐II, and HSY‐III. The results indicated that the HSY polysaccharide mixture, HSY‐I and HSY‐II had hypoglycemic effect.Practical ApplicationThree polysaccharides from Chinese yam tuber were isolated in this study. Their structures were characterized and hypoglycemic effects were evaluated. The result clearly identified the benefits of this plant as a healthy functional food.

Published: September 2017

AbstractAimThis phase II, open‐label study evaluated the efficacy and safety of neoadjuvant therapy with bevacizumab plus XELOX (capecitabine and oxaliplatin) for untreated metastatic colorectal cancer with unresectable liver metastases and assessed conversion of unresectable to resectable metastases after neoadjuvant treatment.MethodsPatients received bevacizumab 5 mg/kg and oxaliplatin 85 mg/m2 on day 1, and capecitabine 1000 mg/m2 twice daily on days 1–5 followed by 2 days of rest in a 14‐day cycle for 12 cycles; bevacizumab was excluded in cycles 6 and 7. Patients were later divided into resected and unresected groups, depending upon whether they underwent curative resection after chemotherapy. Efficacy and safety were evaluated.ResultsOf 45 patients enrolled, 17.8% completed the study. The resection rate of liver metastases after neoadjuvant therapy was 42.2%. The median time to disease progression was 10.1 and 8.7 months in the resected and unresected groups, respectively (P = 0.1341). Response rate was significantly higher in the resected (47.4%) versus the unresected group (34.6%; P = 0.0010), and seven patients achieved complete response (resected group). Overall, 94.3% of adverse events were of mild or moderate severity, and grade ≥3 adverse events occurred in 4.3% and 7.3% of patients in the resected and unresected groups, respectively. The most common adverse events in both groups were palmar‐plantar erythrodysesthesia syndrome, decreased appetite, thrombocytopenia, peripheral neuropathy, fatigue, diarrhea, vomiting, proteinuria and nausea.ConclusionNeoadjuvant therapy with bevacizumab plus XELOX was well tolerated and effective in previously untreated metastatic colorectal cancer patients with initially unresectable liver metastases.
