An Innovative Media Platform-Supported Blended Methodology in English for Dental Purposes Program
Authors: Asgari Arani Jafar 
Published: March 2017

Due to the existing extensive curricula of English for Dental Purposes (EDP) courses and absence of enough weekly hours to cover them in Iran, there is a limited insufficient exposure to English to improve students’ English communication skills to the levels necessary for their future career. Therefore, there have been needs to appraise the present teaching approaches and reform the configuration and context of EDP classes to yield highest profit for their students. The study was designed to address issues central to the perception and expectations of students in regard the use and the impact of the social medium, WhatsApp. As part of this impression, a spectrum of procedures has been depicted to employ this cross-platform messaging application.
This research was conducted among 70 2nd year dentistry students at Kashan University of Medical Sciences, in a course called English for Dental Purposes (EDP). The descriptive research project employing a qualitative and quasi-experimental study was chosen to collect data using a valid and reliable pretest-posttest design. Two groups 35 subjects were randomly selected via simple random sampling. The control group was taught by conventional method, while the experimental group was taught through the proposed whatsApp assisted language learning approach in a blended way. A paired t-test was utilized to compare the results of each group and an independent sample t-test was utilized to compare the results in control and experimental group. The f-ratio value is 7.88138; the t-value is 2.80738. The p-value is .006512 and the result is significant at p < .01.
Therefore, there are good reasons to think WhatsApp-based method of teaching EDP as a more effective approach than the face to face method . The Likert scale questionnaire descriptively analyzed via SPSS 16.00 version revealed experimental group had generally positive attitudes towards Apps-based teaching of academic materials.
This media helps students get to be more capacitated in EDP, advances the class learning of English for Dental Purposes, enhances students' knowledge more satisfactorily, motivates them to gain a positive impact and willingness in their class activities and had resulted in more continuity in study and self-confidence. So, it deserves considering the incorporation of the new application i.e. WhatsApp effectively in the curriculum of EDP pedagogies as an educational means.
Balloon occluded retrograde transvenous obliteration for bleeding gastric varices: Eyes see what the mind knows
Authors: Khera Pushpinder S , Myungsu Lee , Joonsung Choi 
Published: March 2017

AbstractApproximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric varices is mostly the gastrorenal shunt (GRS) which opens into the left renal vein. Balloon-occluded transvenous obliteration (BRTO) involves accessing the GRS with an aim to temporarily occlude its outflow using a balloon catheter and at the same time injecting sclerosant mixture within the varix so as to cause its thrombosis and thereby obliteration. BRTO is one of the mainstays of minimally invasive treatment for bleeding gastric varices. In the minority of cases where the GRS is absent, conventional BRTO is technically not possible. However, accessing the small alternate shunt from the inferior phrenic vein may be possible if one is aware of its existence.

Published: March 2017

Abstract
Background: In dural venous sinus thrombosis (DVST), the mortality ranges 5–30%. Deep venous system involvement and septic dural sinus thrombosis have a higher mortality rate. In acute occlusion, collateral flow may not be established, which may result in significant edema and mass effect. Endovascular interventions may be considered as a treatment option in appropriate high-risk patients with DVST. Materials and Methods: Eight patients with magnetic resonance imaging (MRI)-confirmed dural sinus thrombosis, who did not respond to the conventional standard medical treatment, were subsequently treated with mechanical thrombectomy using the Penumbra System®. In all cases, medical treatment including anticoagulants were continued following the procedure for a minimum period of 1 year. Results: Recanalization of the dural sinus thrombosis was achieved in all 8 cases. There were no immediate or late endovascular-related complications. One death occurred due to an unrelated medical event. At 6 months, there was notable improvement in the modified Rankin Score (mRS), with 5/8 (62%) patients achieving mRS of 2 or less. The follow-up ranged between 3 months and 26 months (mean: 14.5 months), and there were no new neurological events during the follow-up period. Conclusion: Cerebral venous sinus thrombosis is a rare but life-threatening condition that demands timely diagnosis and therapy. In cases of rapidly declining neurological status despite standard therapy with systemic anticoagulation and anti-edema measures, mechanical thrombectomy could be a lifesaving and effective option. In this study, good outcomes were observed in the majority of patients at long-term follow up.

Published: March 2017

Abstract
Background: Tetralogy of Fallot (TOF) is a complex congenital heart disease with anatomic variations. Although the pulmonary valve in TOF is abnormal, it has not been studied well, especially on newer imaging modalities such as multidetector computed tomography (CT), which gives excellent anatomic detail. Aims: The aim of this study was to assess the morphology of pulmonary valve in TOF on CT and evaluate its association with the degree of hypoplasia of infundibulum and pulmonary trunk. Materials and Methods: The cardiac CT scans of 30 patients with TOF were reviewed to evaluate the morphology of the pulmonary valve, infundibulum, and pulmonary arteries. Fisher's exact test was performed to examine the association between pulmonary valve morphology and degree of hypoplasia of the infundibulum and pulmonary trunk. Results: 16.7% of patients with TOF had pulmonary atresia. The prevalence of tricuspid, bicuspid, and absent valves were 10%, 53.3% and 6.7%, respectively. In another 13.3% of patients, although valve tissue was present, exact morphology could not be determined on CT. The commissures of 62.5% of the bicuspid valves were at 12 o'clock and 6 o'clock or slightly off the midline. There was statistically significant association between valve morphology and degree of infundibular hypoplasia (P < 0.001) and calibre of pulmonary trunk (P < 0.001). Conclusion: Morphological abnormality of the pulmonary valve is common in TOF. The most common type of pulmonary valve in TOF patients is bicuspid valve with commissures at 12 o'clock and 6 o'clock or slightly off the midline. Fewer cusps of the pulmonary valve are associated with a more severe degree of pulmonary artery hypoplasia.
Efficient Time-Stepping/Spectral Methods for the Navier-Stokes-Nernst-Planck-Poisson Equations
Authors: Liu Xiaoling , Xu Chuanju 
Published: March 2017

AbstractThis paper is concerned with numerical methods for the Navier-Stokes-Nernst-Planck-Poisson equation system. The main goal is to construct and analyze some stable time stepping schemes for the time discretization and use a spectral method for the spatial discretization. The main contribution of the paper includes: 1) an useful stability inequality for the weak solution is derived; 2) a first order time stepping scheme is constructed, and the non-negativity of the concentration components of the discrete solution is proved. This is an important property since the exact solution shares the same property. Moreover, the stability of the scheme is established, together with a stability condition on the time step size; 3) a modified first order scheme is proposed in order to decouple the calculation of the velocity and pressure in the fluid field. This new scheme equally preserves the non-negativity of the discrete concentration solution, and is stable under a similar stability condition; 4) a stabilization technique is introduced to make the above mentioned schemes stable without restriction condition on the time step size; 5) finally we construct a second order finite difference scheme in time and spectral discretization in space. The numerical tests carried out in the paper show that all the proposed schemes possess some desirable properties, such as conditionally/unconditionally stability, first/second order convergence, non-negativity of the discrete concentrations, and so on.
Delaunay Graph Based Inverse Distance Weighting for Fast Dynamic Meshing
Authors: Wang Yibin , Qin Ning , Zhao Ning 
Published: March 2017

AbstractA novel mesh deformation technique is developed based on the Delaunay graph mapping method and the inverse distance weighting (IDW) interpolation. The algorithm maintains the advantages of the efficiency of Delaunay graph mapping mesh deformation while it also possesses the ability of better controlling the near surface mesh quality. The Delaunay graph is used to divide the mesh domain into a number of sub-domains. On each sub-domain, the inverse distance weighting interpolation is applied, resulting in a similar efficiency as compared to the fast Delaunay graph mapping method. The paper will show how the near-wall mesh quality is controlled and improved by the new method
Simulating Magnetohydrodynamic Instabilities with Conservative Perturbed MHD Model Using Discontinuous Galerkin Method
Authors: Ma Jun , Guo Wenfeng , Yu Zhi 
Published: March 2017

AbstractIn magnetically confined plasma research, the understandings of small and large perturbations at equilibrium are both critical for plasma controlling and steady state operation. Numerical simulations using original MHD model can hardly give clear picture for small perturbations, while non-conservative perturbed MHD model may break conservation law, and give unphysical results when perturbations grow large after long-time computation. In this paper, we present a nonlinear conservative perturbed MHD model by splitting primary variables in original MHD equations into equilibrium part and perturbed part, and apply an approach in the framework of discontinuous Galerkin (DG) spatial discretization for numerical solutions. This enables high resolution of very small perturbations, and also gives satisfactory non-smooth solutions for large perturbations, which are both broadly concerned in magnetically confined plasma research. Numerical examples demonstrate satisfactory performance of the proposed model clearly. For small perturbations, the results have higher resolution comparing with the original MHD model; for large perturbations, the non-smooth solutions match well with existing references, confirming reliability of the model for instability investigations in magnetically confined plasma numerical research.
The revised ‘Common Time’ program as a strategy for student engagement and retention at university

Published: March 2017

The School of Human Services and Social Work at Griffith University (Brisbane, Australia) developed the Common Time program in 2002 for its first year undergraduate students to increase student success in academic learning and to facilitate student engagement with staff and fellow students. Common Time consists of a series of facilitated forums during the initial weeks of each semester, where the first year cohort meet weekly to discuss general first year issues and receive information relevant to the first year university experience. As the program underwent changes in 2013, this paper discusses the findings of an evaluative research initiative. The results indicate that the revised 2013 Common Time program was, for the most part, effective in orientating and engaging these first year students during their transition into university study. However, further revisions to the program are needed to improve students’ opportunities to build meaningful social networks in particular.
Victorian maternal child health nurses’ knowledge, attitudes and beliefs towards national registration changes
Authors: Breach Rayleen , Jones Linda K. 
Published: March 2017

In 2010 National Registration for nurses was established which was likely to impact the role of the maternal and child health nurses (MCH) in Victoria. This study explored the perceived impact of the national changes to the MCH nurse workforce in Victoria following the implementation of national registration and a proposed national service framework. A qualitative exploratory descriptive design was employed with the purpose of exploring the knowledge, attitudes and beliefs of Key Stakeholders (KSH) to the recent changes and perceived impact to Victorian MCH nurses. The significance of this study lies with understanding the gaps in current knowledge of KSH to the national changes. Outlined briefly in this paper will be main findings from the KSH. This involved interviewing 12 KSH from management positions, including Local Government Coordinators, Policy Advisors to the Department of Education and Early Childhood Development, the Municipal Association of Victoria, along with academics from Universities that provide postgraduate Child and Family Health education programs for the MCH nurse qualification. Date was transcribed verbatim and content analysis used. Categories were developed by identifying recurrent patterns from the data, labels were then chosen which reflected the participant’s words: “common standard”; “losing our identity”; “universal service”; “we do it well” and “imposed from above”. Overall the KSH were concerned how the disparity in education and qualifications would be resolved and the effect this would have on the service. Findings from this study highlight the importance of comprehensively investigating services offered by all jurisdictions and using collaboration, communication and leadership to effectively introduce change.

Comparision of Different Raw Densities and Board Thicknesses in the Production of Enzymatically Bonded Fiberboards
Authors: Kirsch Alexander , Reuter Patrick , Kharazipour Alireza , Euring Markus 
Published: March 2017

Reducing CO2 emissions for the long term is an important issue in countering climate change. For this reason, the use of renewable construction materials inter alia wood-based materials is becoming increasingly important. Wood based materials often depend on petrochemical-based binding agents, most of which contain and emit formaldehyde. This causes environmental and health-related difficulties that could be rectified by avoiding the utilization of these adhesives. For this purpose, enzymatically bonded medium-density fiberboards (MDF) with a targeted raw density of 650 kg/m³ and 750 kg/m³ and high-density fiberboards (HDF) with a density of 900 kg/m³ were produced in different thicknesses. Laccase-Mediator-System (LMS) was applied to manufacture the boards and to compare them to those glued with UF and inactivated laccase, respectively. These panels were tested in terms of their physical technical properties, such as internal bond strength (IB), modulus of rupture (MOR) and thickness swelling (TS) after 24 h immersion. The aim was to show the correlation between density and these properties for fiberboards bonded this way. Most panels meet the requirements of the European standard when LMS and UF-resin were used. The possibility to produce fiberboards bonded with alternative bonding agents opens up the way to alternative, innovative, healthy and environmental-friendly wood based products.

Abstract
To ensure that the Comprehensive Osteopathic Medical Licensing Examination- USA (COMLEX-USA) reflects the evolving practice of osteopathic medicine, the National Board of Osteopathic Medical Examiners has developed new content and format specifications for an enhanced, competency-based examination program to be implemented with COMLEX-USA Level 3 in 2018. This article summarizes the evidence-based design processes that served as the foundation for blueprint development and the evidence supporting its validity. An overview is provided of the blueprint’s 2 dimensions: Competency Domains and Clinical Presentations. The authors focus on the evidence that supports interpretation of test scores for the primary and intended purpose of COMLEX-USA, which is osteopathic physician licensure. Important secondary uses and the educational and catalytic effect of assessments are also described. This article concludes with the National Board of Osteopathic Medical Examiners’ plans to ensure that the COMLEX-USA series remains current and meets the needs of its stakeholders-the patients who seek care from osteopathic physicians.
An Analysis of Use of conditional Sentences by Arab Students of English
Authors: Haza' Al Rdaat Sadam , Gardner Sheena 
Published: March 2017

Conditional sentences are made of two clauses namely “if-clause” and “main clause”. Conditionals have been noted by scholars and grammarians as a difficult area of English for both teachers and learners. The two clauses of conditional sentences and their form, tense and meaning could be considered the main difficulty of conditional sentences. In addition, some of non-native speakers do not have sufficient knowledge of the differences between conditional sentences in the two languages and they tried to solve their problems in their second language by using their native language. The aim of this study was to analyse the use of conditional sentences by Arab students of English in semantic and syntactic situations. For the purpose of this study, 20 Arab students took part in the questionnaire, they were all studying different subjects and degrees (bachelor, master and PhD) at Coventry University. The results showed that the use of type three conditionals and modality can be classified as the most difficult issues that students struggle to understand and use.

Abstract

The article describes the preparation of 2‐(2‐(Dicyclohexylphosphino)phenyl)‐1‐methyl‐1
H
‐indole (CM‐phos).We selected the Fischer indole synthesis as our primary tool to synthesize the indole templates from phenylhydrazine and 2’‐bromoacetophenone. With the methylated ligand precursor, CM‐phos could be afforded easily by lithiation and subsequently trapping with chlorodicyclohexylphosphine. It should be noted that CM‐phos in combination with the precatalyst palladium(II) acetate is highly active and effective in amination and Suzuki cross‐coupling reaction of aryl mesylates.

Abstract
The article describes the synthesis of 5‐(Hydroxymethyl)furfural (HMF). Under investigations are broad range of HMF conversions to useful chemicals for the industry such as polymer industry, pharmacy, fuel chemistry. The procedure described herein is based on simple precipitation of the reaction media (tetraethyl ammonium bromide) allowing complete separation of HMF in high yields and purity in a single step without extraction or column chromatography. Although HMF is known to be unstable, no formation of side products or decomposition was observed during the work up procedure and it was isolated with above 95% purity by HPLC and can be directly used in further reactions or if required stored in the freezer.
