Numerical investigation of heat and mass transfer in three-dimensional MHD nanoliquid flow with inclined magnetization
No full textAbstract
Heat and mass transfer rate by using nanofluids is a fundamental aspect of numerous industrial processes. Its importance extends to energy efficiency, product quality, safety, and environmental responsibility, making it a key consideration for industries seeking to improve their operations, reduce costs, and meet regulatory requirements. So, the principal objective of this research is to analyze the heat and mass transfer rate for three-dimensional magneto hydrodynamic nanoliquid movement with thermal radiation and chemical reaction over the dual stretchable surface in the existence of an inclined magnetization, and viscous dissipation. The flow is rotating with constant angular speed

about the axis of rotation because such flows occur in the chemical processing industry and the governing equations of motion, energy, and concentration are changed to ODEs by transformation. The complex and highly nonlinear nature of these equations makes them impractical to solve analytically so tackled numerically at MATLAB. The obtained numerical results are validated with literature and presented through graphs and tables. Increasing the Eckert number from

Semantically-enhanced topic recommendation systems for software projects
No full textSoftware-related platforms such as GitHub and Stack Overflow, have enabled their users to collaboratively label software entities with a form of metadata called topics. Tagging software repositories with relevant topics can be exploited for facilitating various downstream tasks. For instance, a correct and complete set of topics assigned to a repository can increase its visibility. Consequently, this improves the outcome of tasks such as browsing, searching, navigation, and organization of repositories. Unfortunately, assigned topics are usually highly noisy, and some repositories do not have well-assigned topics. Thus, there have been efforts on recommending topics for software projects, however, the semantic relationships among these topics have not been exploited so far. In this work, we propose two recommender models for tagging software projects that incorporate the semantic relationship among topics. Our approach has two main phases; (1) we first take a collaborative approach to curate a dataset of quality topics specifically for the domain of software engineering and development. We also enrich this data with the semantic relationships among these topics and encapsulate them in a knowledge graph we call SED-KGraph. Then, (2) we build two recommender systems; The first one operates only based on the list of original topics assigned to a repository and the relationships specified in our knowledge graph. The second predictive model, however, assumes there are no topics available for a repository, hence it proceeds to predict the relevant topics based on both textual information of a software project (such as its README file), and SED-KGraph. We built SED-KGraph in a crowd-sourced project with 170 contributors from both academia and industry. Through their contributions, we constructed SED-KGraph with 2,234 carefully evaluated relationships among 863 community-curated topics. Regarding the recommenders’ performance, the experiment results indicate that our solutions outperform baselines that neglect the semantic relationships among topics by at least 25% and 23% in terms of Average Success Rate and Mean Average Precision metrics, respectively. We share SED-KGraph, as a rich form of knowledge for the community to re-use and build upon. We also release the source code of our two recommender models, KGRec and KGRec+ (https://github.com/mahtab-nejati/KGRec).Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Software Engineerin
Relationship between Maternal Serum Copper Level and Birth Weight Neonate
No full textBackground and Objectives: Low birth weight (LBW) is a major public health problem. LBW is associated with increased neonatal morbidity and mortality. There is no consensus in the literature as to whether maternal copper nutrition is associated with pregnancy outcome or fetal growth. Methods: This case-control study was carried out at Alavi Hospital in Ardabil between August 2008 and August 2009. 56 women who had delivered low-birth- weight infants (<2500gr) were taken as the case group, and from the mothers who had delivered normal birth weight infants (≥2500gr), 56 were selected at random as the control group. Venous blood samples were obtained from the mothers. Serum zinc level was determined by the Atomic Absorption Spectrophotometer method. Results: Mean of birth weight in infants, maternal age, body mass index in mothers and socioeconomic or demographic factors did not differ between cases and control groups. Maternal copper concentration (μg/dl) differed between Cases and Controls; 231.75±38.12μg/dl vs. 204.42±31.30μg/dl respectively. There is a significant difference (p<0.001) in the serum copper concentration between the two groups. Conclusion: There is a negative relation between low infant birth weight and maternal copper concentration
Patient's Electronic Environment Information Rights: patient's information rights
No full textBackground and Aim: Electronic health record is one of the most important achievements of the eHealth to achieve patient-centered care. The aim of patient-centered care is the accessibility of all patient information to clinicians to have the best decisions for the patients. Creating an environment for sharing information and developing e-health information caused the security and privacy of health information of patients to become an important and challenging issue. In this regard, healthcare organizations must create a security solution to protect the rights of their patients.
Materials and Methods: This review is based on library research and Internet searches in the major databases such as Web of science, Emerald, Proquest, EBSCO host research, PubMed, and search engines like Google and Google Scholar. In this review, essays, books in the field of medical informatics, and the security of information systems in the health system have been studied.
Ethical Considerations: Publication of the results is carried out without bias, honestly, and by citing the original reliable resources and references.
Findings In this review, how to maintain information security programs and health information systems in addition to improving quality of care to achieve three main objectives related to security, including confidentiality, accuracy, and the availability around three core axes of administrative safeguards, physical safeguards, and technical safeguards are discussed.
Conclusion: The health centers should be consistent in four main areas standards, rules and policies related to the contribution and access to information, communications and operations management, access control and security of human resources including awareness and education of the users about security issues should involve a range of users ranging from therapists to legal and technical experts and always consider the principle of "protecting the rights of patients with convenient access to patient information" to develop their security and development of programs.

A Case Report of Decompensated Cirrhosis of Liver with Sideroblastic Anemia.
No full textUNLABELLED: A 35-year-old man was admitted to hospital with severe anemia. Two years back, he had presented with bleeding esophageal varices and subsequently diagnosed as a case of chronic liver disease with portal hypertension. He was then treated with esophageal band ligation. He tested positive for hepatitis B surface antigen with HBV DNA levels of 4 × 106 copies/ml by PCR. His repeat endoscopy showed grade 1 esophageal varices with no evidence of recent or active bleeding. On further investigation, his bone marrow showed dimorphic erythroid hyperplasia with ring sideroblasts and diagnosis of sideroblastic anemia was made. Although rarely, it was suggested that as cirrhosis is a chronic process, it may cause nutritional deficiency, which in turn may lead to the development of anemia.

Abdominal cystic echinococcosis in Bangladesh: a hospital-based study
No full textIntroduction: Cystic echinococcosis (CE) is reported from nearly all geographic areas of Bangladesh, but little information is available on its epidemiologic and clinical features. The aim of this study was to describe the clinical manifestations of hepatic and abdominal CE cases presenting to tertiary referral hospitals in Dhaka, Bangladesh.
Methodology: A retrospective study was conducted via chart reviews of hepatic and abdominal CE patients under care at tertiary referral hospitals in Dhaka, Bangladesh, between 2002 and 2011. Age, sex, education level, occupation, urban versus rural residence, drinking water source, history of dog ownership, cyst type and location, and clinical manifestations were recorded for all patients.
Results: Of the 130 patients enrolled, 92 (70.8%) were female and 38 (29.2%) were male. The majority of patients were from rural (76.2%) rather than urban (23.8%) areas. All cases were from the northern part of the country, with no cases reported from the south or southeast. Most patients were between 21 and 40 years of age. A total of 119 patients (91.5%) had cysts only in the liver, with the remaining 8.5% having cysts in both the liver and lungs or in the abdominal cavity. Seventy-six (58.5%) of the hepatic cysts were stage CE1, indicating recent infection.
Conclusions: Active transmission of Echinococcus granulosus appears to be occurring in Bangladesh, as indicated by the high number of CE1 hepatic cysts seen at tertiary care hospitals

No full textABSTRACTBackgroundHepatic venous pressure gradient (HVPG) reflects the portal pressure in patients with cirrhotic portal hypertension. The aim of the study was to assess the relation of HVPG to variceal size, Child—Pugh status, and variceal bleeding.Materials and methodsA total of 96 patients with cirrhosis of liver were enrolled prospectively and each patient's HVPG level was measured via the transfemoral route. Clinical and biochemical evaluation and upper gastrointestinal (GI) endoscopy were done in each subject. Severity of cirrhosis was assessed by Child's status.ResultsThe mean HVPG was higher in patients with Child's B and C (14.10 ± 7.56 and 13.64 ± 7.17 mm Hg respectively) compared with those of Child's A (10.15 ± 5.63 mm Hg). The levels of HVPG differed significantly between Child's classes A and B (p = 0.011) and Child's A and C (p = 0.041). The mean HVPG was also higher in bleeders compared with nonbleeders with large varices (17.7 ± 5.5vs14.9 ± 4.7 mmHg respectively; p = 0.006).ConclusionHepatic venous pressure gradient seems to be important to assess the severity of liver cirrhosis.How to cite this articleAl Mahtab M, Noor E Alam SM, Rahim MA, Alam MA, Khondaker FA, Moben AL, Mohsena M, Akbar SMF.
