1Optimal selection of annulus radius ratio to enhance heat transfer with minimum entropy generation in developing laminar forced convection of water-Al2O3 nanofluid flow显示文摘Heat transfer and entropy generation of developing laminar forced convection flow of water-Al_2O_3 nanofluid in a concentric annulus with constant heat flux on the walls is investigated numerically. In order to determine entropy generation of fully developed flow, two approaches are employed and it is shown that only one of these methods can provide appropriate results for flow inside annuli. The effects of concentration of nanoparticles, Reynolds number and thermal boundaries on heat transfer enhancement and entropy generation of developing laminar flow inside annuli with different radius ratios and same cross sectional areas are studied. The results show that radius ratio is a very important decision parameter of an annular heat exchanger such that in each Re, there is an optimum radius ratio to maximize Nu and minimize entropy generation. Moreover, the effect of nanoparticles concentration on heat transfer enhancement and minimizing entropy generation is stronger at higher Reynolds.Siavashi Majid Jamali Mohammad 2017Journal of Central South University2017,24,8:23
2Persistent alanine aminotransferase elevation among the general Iranian population: Prevalence and causes显示文摘AIM: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran. METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was ≥ 40 U/L, it was rechecked twice within 6 mo. Those with ≥ 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran.Raika Jamali Mahmoodreza Khonsari Shahin Merat Masoud Khoshnia Elham Jafari Alireza Bahram Kalhori Hassan Abolghasemi Sedighe Amini Mahtab Maghsoudlu Mohammad Reza Deyhim Houri Rezvan Akram Pourshams 2008World Journal of Gastroenterology2008,14,18:7
3Serum adipokines might predict liver histology findings in non-alcoholic fatty liver disease显示文摘AIM: To assess significance of serum adipokines to determine the histological severity of non-alcoholic fatty liver disease.METHODS: Patients with persistent elevation in serum aminotransferase levels and well-defined characteristics of fatty liver at ultrasound were enrolled. Individuals with a history of alcohol consumption, hepatotoxic medication, viral hepatitis or known liver disease were excluded. Liver biopsy was performed to confirm nonalcoholic liver disease(NAFLD). The degrees of liver steatosis, lobular inflammation and fibrosis were determined based on the non-alcoholic fatty liver activity score(NAS) by a single expert pathologist. Patients with a NAS of five or higher were considered to have steatohepatitis. Those with a NAS of two or lower were defined as simple fatty liver. Binary logistic regression was used to determine the independent association of adipokines with histological findings. Receiver operating characteristic(ROC) analysis was employed to determine cut-off values of serum adipokines to discriminate the grades of liver steatosis,lobular inflammation and fibrosis. RESULTS: Fifty-four participants aged 37.02 ± 9.82 were enrolled in the study. Higher serum levels of visfatin, IL-8, TNF-α levels were associated independently with steatosis grade of more than 33% [β = 1.08(95%CI: 1.03-1.14), 1.04(95%CI: 1.008-1.07), 1.04(95%CI: 1.004-1.08), P < 0.05]. Elevated serum IL-6 and IL-8 levels were associated independently with advanced lobular inflammation [β = 1.4(95%CI: 1.09-1.8), 1.07(95%CI: 1.003-1.15), P < 0.05]. Similarly, higher TNF-α, resistin, and hepcidin levels were associated independently with advanced fibrosis stage [β = 1.06(95%CI: 1.002-1.12), 19.86(95%CI: 2.79-141.19), 560.72(95%CI: 5.98-5255.33), P < 0.05]. Serum IL-8 and TNF-α values were associated independently with the NAS score, considering a NAS score of 5 as the reference value [β = 1.05(95%CI: 1.01-1.1), 1.13(95%CI: 1.04-1.22), P < 0.05]. CONCLUSION: Certain adipokines may determine the severity of NAFLD histology accurately.Raika Jamali Mohsen Razavizade Abbas Arj Mohammad Hossein Aarabi 2016World Journal of Gastroenterology2016,22,21:7
4Use of 2-(tert-butoxy)-N-(3-carbamothioylphenyl)acetamide and graphene oxide for separation and preconcentration of Fe(Ⅲ),Ni(Ⅱ),Cu(Ⅱ) and Zn(Ⅱ) ions in different samples显示文摘A simple and selective method using a column packed with graphene oxide(GO) as a solid phase extractant has been developed for the multi-element preconcentration of Fe(Ⅲ),Ni(Ⅱ),Cu(Ⅱ) and Zn(Ⅱ)ions prior to flame atomic absorption spectrometric determinations.The method is based on the sorption of mentioned ions on synthesized GO using 2-(tert-butoxy)-N-(3-carbamothioylphenyl)acetamide as a chelating agent.Several parameters on the extraction and complex formation were optimized.Under the optimized conditions(pH 6,flow rate 9 mL/min),metal ions were retained on the column,then quantitatively eluted by HNO3solution(5 mL,3.0 mol/L).The preconcentration factor was calculated as250.The detection limits for the analyte ions of interest were found in the range of 0.11 ng/mL(Ni2+) to0.63 ng/mL(Cu2+).The column packed with GO was adequate for metal ions separation in matrixes containing alkali,alkaline earth,transition and heavy metal ions.Mohammad Reza Pourjavid Ali Akbari Sehat Majid Haji Hosseini Mohammad Rezaee Masoud Arabieh Seyed Reza Yousefi Mohammad Reza Jamali 2014Chinese Chemical Letters2014,25,5:2

16Improvement of the thermoelectric efficiency of pyrene-based molecular junction with doping engineering显示文摘In this study, the thermoelectric properties of pyrene molecule doped with boron and nitrogen atom at different sites of molecule are investigated using density functional theory and none-equilibrium Green's function formalism in the linear response regime. Our calculations show that when the impurities are added to the edge of the molecule, the anti-resonant peaks will appear in the transmission diagram in the vicinity of the Fermi energy level. So it increases the thermoelectric figure of merit of the system in comparison with the one that the impurity is located in the center of molecule. Additionally,the seebeck coefficient signs are not the same among the B, N, and N & B doped devices, indicating that the types of the carriers can be changed with different types of doping.Mohammad Farid Jamali Meysam Bagheri Tagani Hamid Rahimpour Soleimani 2017Chinese Physics B2017,26,12:0
