However, due to the new structure of the cloud computing model, several security concerns have been raised and many other security threats have been needed to be reevaluated according to the cloud structure. Besides, the traditional security risk assessment methods become unfit for cloud computing model due to its new distinguished characteristics. In this paper, we analysis the ability to assess the security risks in cloud computing environments

The Mediating Role of Marketing Innovation Between Internal Social Media Utilization and Business Performance of Smes in Saudi Arabia

Purpose: The usage of social media (SM) by small and medium enterprises (SMEs) received relatively less attention and the findings in the literature are mixed in terms of the effect of SM on SME performance. The purpose of this study is to examine the effect of SM utilization on SME business performance (SMEBP) in Saudi Arabia.   Theoretical Framework: Based on the resource-based view, this study proposed that SM internal utilization (SMIU) affects positively the SMEBP and marketing innovation (MI). MI is expected to affect the SMEBP and mediate the effect of SMIU on SME performance (profitability (PR) and business growth (BG).   Design/Methodology/Approach: The population of this study is the SMEs in Al-Riyadh city in Saudi Arabia. A simple random sampling is deployed. The data was collected using a questionnaire. A total of 451 respondents representing SMEs participated in this study.   Findings: The finding was derived using Smart PLS version 4. The findings showed that SMIU affected positively PR and BG of SME and MI. MI affected positively the PR and BG of SME and mediated partially the effect of SMIU on PR and BG of SME.   Research practical Implication:  Decision makers are advised to deploy SM more effectively and to create a rewarding culture for innovative ideas to improve performance.   Originality/Value: This study helps to enhance the understanding regarding the role of marketing innovation and social media internal usage in improving the performance of SMEs in emerging economies

A Food Frequency Questionnaire for Hemodialysis Patients in Bangladesh (BDHD-FFQ): Development and Validation

Diet is a recognized risk factor and cornerstone for chronic kidney disease (CKD) management; however, a tool to assess dietary intake among Bangladeshi dialysis patients is scarce. This study aims to validate a prototype Bangladeshi Hemodialysis Food Frequency Questionnaire (BDHD-FFQ) against 3-day dietary recall (3DDR) and corresponding serum biomarkers. Nutrients of interest were energy, macronutrients, potassium, phosphate, iron, sodium and calcium. The BDHD-FFQ, comprising 132 food items, was developed from 606 24-h recalls and had undergone face and content validation. Comprehensive facets of relative validity were ascertained using six statistical tests (correlation coefficient, percent difference, paired t-test, cross-quartiles classification, weighted kappa, and Bland-Altman analysis). Overall, the BDHD-FFQ showed acceptable to good correlations (p 0.05). Cross-quartile classification indicated that <10% of patients were incorrectly classified. Weighted kappa statistics showed agreement with all but iron. Bland-Altman analysis showed positive mean differences were observed for all nutrients when compared to 3DDR, whilst energy, carbohydrates, fat, iron, sodium, and potassium had percentage data points within the limit of agreement (mean ± 1.96 SD), above 95%. In summary, the BDHD-FFQ demonstrated an acceptable relative validity for most of the nutrients as four out of the six statistical tests fulfilled the cut-off standard in assessing dietary intake of CKD patients in Bangladesh

Design and biomechanical performance analysis of a user-friendly orthotic device

Material selection and proper design are essential for developing a new product, especially biomedical devices. Stance-control-orthosis (SCO) are walking assistive device for the patients with weak quadriceps. This manuscript presents the development of a prefabricated SCO with suitable material and design. It is 45 lighter than commercially available prefabricated device. It contains some adjustable features to make it competent for wide range of patients in terms of height (153-183 cm) and weight. Finite element analysis (FEA) was used for selecting the best material and optimizing weight of different components of this device. Basic structures the device were made of aluminum alloy 7075-T6. Carbon-fiber epoxy composite material was used for fabricating the support braces of the device and a polypropylene made foot part was included. Components were fabricated according to FEA results and had been evaluated by mechanical tests. Almost similar results of FEA were found during mechanical tests. The device gait performance was assessed and compared with commercially available prefabricated SCO. The results revealed a better gait. Proper material selection and design made this orthotic device light, structurally stable, functionally suitable and cosmetically acceptable to users. (C) 2014 Elsevier Ltd. All rights reserved

Cloud computing adoption challenges

Despite the cloud computing being a new approach to computing service delivery or just a kind of unstandardized distributed systems or maybe a high level of IT outsourcing, cloud computing is expected to become the most common computing language in the next decades. There are many challenges that slow the adoption of cloud computing. In this paper, we discuss some cloud computing adaptation challenges from the perspectives of cloud service providers and clients in terms of standards, security, legislation, performance, and service cost

Microfluidic Biochemical Sensor Based On Circular SIW-DMS Approach For Dielectric Characterization Application

This work proposes an advancement of microwave planar resonator sensor with high sensitivity for microfluidic dielectric characterization. The physical design was employed based on circular substrate integrated waveguide (CSIW) with an integration of defected microstrip structure (DMS). This approach can be applied to accelerate the dielectric detection, structure miniaturization and material differentiation. The presented sensor operates based on variations in the dielectric properties of solvents in the vicinity of a planar open-ended microstrip resonator device. Further analysis in volume and concentration were performed to validate the reliability of the sensor. Validation and functionality of the sensor were investigated by experimental and results comparison. A mathematical model was developed to determine the dielectric constant and the loss tangent of the microfluidic samples. The average error detection has a lower percentage value of 0.11% by comparison to the commercial and ideal dielectric properties of the aqueous samples. The maximum relative error detection, ±0.37% implied better accuracy compared to the existing resonator sensors with more than 400 of the Q-factor. The proposed CSIW-DMS sensor was found to give higher accuracy and detection response; besides easier to fabricate, and compatible for integration with other electronic components in an RF sensor for variety of application

Inclusivity in global research.

Hemodialysis (HD) is a treatment for ensuring the survival of end-stage kidney disease (ESKD) patients, and nutrition care is integral to their management. We sent questionnaires to evaluate the total dialysis service capacity and nutrition services across all dialysis facilities (DF) in Bangladesh, with responses from 149 out of 166 active DFs. Survey results revealed that 49.7% of DFs operated two shifts, and 42.3% operated three shifts daily, with 74.5% holding between one and ten dialysis machines. Sixty-three percent of DFs served between one and 25 patients per week, and 77% of patients received twice-weekly dialysis. The average cost for first-time dialysis was 2800 BDT per session (range: 2500–3000 BDT), but it was lower if reused dialyzers were used (2100 BDT, range: 1700–2800 BDT). Nutritionists were available in only 21% of the DFs. Parameters related to nutritional health screening (serum albumin, BMI, MIS-malnutrition inflammation assessment, and dietary intakes) were carried out in 37.6%, 23.5%, 2%, and 2% of the DFs, respectively, only if recommended by physicians. Nutrition education, if recommended, was provided in 68.5% of DFs, but only in 17.6% of them were these delivered by nutritionists. The recommendation for using renal-specific oral nutrition supplements (ONS) is not a familiar practice in Bangladeshi DFs and, therefore, was scarcely recommended. Dialysis capacity across Bangladesh is inadequate to meet current or projected needs and nutrition education and support across the DFs to benefit improving patients’ quality of life is also inadequate.</div
