| 1 | Unsteady MHD flow and heat transfer near stagnation point over a stretching/shrinking sheet in porous medium filled with a nanofluid显示文摘In this article, the unsteady magnetohydrodynamic(MHD) stagnation point flow and heat transfer of a nanofluid over a stretching/shrinking sheet is investigated numerically. The similarity solution is used to reduce the governing system of partial differential equations to a set of nonlinear ordinary differential equations which are then solved numerically using the fourth-order Runge–Kutta method with shooting technique. The ambient fluid velocity, stretching/shrinking velocity of sheet, and the wall temperature are assumed to vary linearly with the distance from the stagnation point. To investigate the influence of various pertinent parameters, graphical results for the local Nusselt number, the skin friction coefficient,velocity profile, and temperature profile are presented for different values of the governing parameters for three types of nanoparticles, namely copper, alumina, and titania in the water-based fluid. It is found that the dual solution exists for the decelerating flow. Numerical results show that the extent of the dual solution domain increases with the increases of velocity ratio, magnetic parameter, and permeability parameter whereas it remains constant as the value of solid volume fraction of nanoparticles changes. Also, it is found that permeability parameter has a greater effect on the flow and heat transfer of a nanofluid than the magnetic parameter. | Sadegh Khali Saeed Dinarvand Reza Hossei Hossein Tamim Ioan Pop | 2014 | Chinese Physics B2014,23,4: | 4 |
| 2 | Aspirin use for primary prophylaxis: Adverse outcomes in non-variceal upper gastrointestinal bleeding显示文摘AIM: To compare outcomes of patients with nonvariceal upper gastrointestinal bleeding(NVUGIB) taking aspirin for primary prophylaxis to those not taking it.METHODS: Patients not known to have any vascular disease(coronary artery or cerebrovascular disease) who were admitted to the American University of Beirut Medical Center between 1993 and 2010 with NVUGIB were included. The frequencies of in-hospital mortality, re-bleeding, severe bleeding, need for surgery or embolization, and of a composite outcome defined as the occurrence of any of the 4 bleeding related adverse outcomes were compared between patients receiving aspirin and those on no antithrombotics. We also compared frequency of in hospital complications and length of hospital stay between the two groups.RESULTS: Of 357 eligible patients, 94 were on aspirin and 263 patients were on no antithrombotics(controlgroup). Patients in the aspirin group were older, the mean age was 58 years in controls and 67 years in the aspirin group(P < 0.001). Patients in the aspirin group had significantly more co-morbidities, including diabetes mellitus and hypertension [25(27%) vs 31(112%) and44(47%) vs 74(28%) respectively,(P = 0.001)], as well as dyslipidemia [21(22%) vs 16(6%), P < 0.0001).Smoking was more frequent in the aspirin group [34(41%) vs 60(27%), P = 0.02)]. The frequencies of endoscopic therapy and surgery were similar in both groups. Patients who were on aspirin had lower inhospital mortality rates(2.1% vs 13.7%, P = 0.002),shorter hospital stay(4.9 d vs 7 d, P = 0.01), and fewer composite outcomes(10.6% vs 24%, P = 0.01). The frequencies of in-hospital complications and re-bleeding were similar in the two groups.CONCLUSION: Patients who present with NVUGIB while receiving aspirin for primary prophylaxis had fewer adverse outcomes. Thus aspirin may have a protective effect beyond its cardiovascular benefits. | Karina M Souk Hani M Tamim Hussein A Abu Daya Don C Rockey Kassem A Barada | 2016 | World Journal of Gastrointestinal Surgery2016,8,7: | 3 |
| 3 | Prevalence and factors associated with irritable bowel syndrome among university students in Lebanon:Findings from a cross-sectional study显示文摘AIM: To describe the bowel habits and the prevalence of irritable bowel syndrome(IBS) and to investigate the influence of health behavior and social factors on IBS prevalence in university students. METHODS: This cross-sectional study was conducted at five major universities in Greater Beirut and its suburbs, between February and June 2014. Using a convenience sample, a total of 813 students aged 18 years old and above participated in this study. Participants were asked to complete a comprehensive anonymous questionnaire which detailed characteristics on socio-demographic, health-related, and lifestyle factors, as well as IBS. The ROME Ⅲ criteria were used as a tool to ascertain IBS. A χ2 test was used to determine differences between categorical variables; stepwise logistic regression was used to measure the association between IBS and its risk factors.RESULTS: An overall prevalence of IBS of 20% was recorded among university students. The bivariate analysis showed that females were significantly more likely to report having IBS than males(29.1% vs 18.2%, P < 0.01). Those living at the school dormitory or in a private residence(39.5%) were more likely to have IBS than those living with their families(16.3%)(P < 0.01). The multivariate analysis showed that those who had a relatively high family income level(US$ > 2000) were almost 6 times more likely to report havingIBS than their counterparts.CONCLUSION: This is the first study to describe the nature of IBS among young adults in Lebanon. The prevalence of IBS among university students in our sample was higher than that reported in the West. | Christy Costanian Hala Tamim Shafika Assaad | 2015 | World Journal of Gastroenterology2015,21,12: | 3 |
