SOLUTION OF THE RAYLEIGH PROBLEM FOR A POWER-LAW NON-NEWTONIAN CONDUCTING FLUID VIA GROUP METHOD

引用

Applied Mathematics and Mechanics(English Edition) 2002年第6期23卷 639-646页

作者： Mina B.Abd-el-Malek Nagwa A.Badran Hossam S.hassan Department of Engineering Mathematics and Physics Faculty of Engineering Alexandria University 21544 Alexandria Egypt Department of Basic and Applied Science Arab Academy for Science and Technology and Maritime Transport P O Box 1029 Alexandria Egypt

An investigation is made of the magnetic Rayleigh problem where a semi_infinite plate is given an impulsive motion and thereafter moves with constant velocity in a non_Newtonian power law fluid of infinite extent. The solution of this highly non_linear problem is obtained by means of the transformation group theoretic approach. The one_parameter group transformation reduces the number of independent variables by one and the governing partial differential equation with the boundary conditions reduce to an ordinary differential equation with the appropriate boundary conditions. Effect of the some parameters on the velocity u(y,t) has been studied and the results are plotted.

Rotation Scaling and Translation Invariants of 3D Radial Shifted Legendre Moments

引用

International Journal of Automation and computing 2018年第2期15卷 169-180页

作者： Mostafa el Mallahi Jaouad E1Mekkaoui Areal Zouhri Hicham Amakdouf hassan Qjidaa Faculty of Sciences Sidi Mohamed Ben Abdellah University Fez Morocco Department of Mathematics and Computer Science Polydisciplinary Faculty Sultan Moulay Slimane University Beni Mellal Morocco

This paper proposes a new set of 3D rotation scaling and translation invariants of 3D radially shifted Legendre moments. We aim to develop two kinds of transformed shifted Legendre moments： a 3D substituted radial shifted Legendre moments （3DSRSLMs） and a 3D weighted radial one （3DWRSLMs）. Both are centered on two types of polynomials. In the first case, a new 3D ra- dial complex moment is proposed. In the second case, new 3D substituted/weighted radial shifted Legendremoments （3DSRSLMs/3DWRSLMs） are introduced using a spherical representation of volumetric image. 3D invariants as derived from the sug- gested 3D radial shifted Legendre moments will appear in the third case. To confirm the proposed approach, we have resolved three is- sues. To confirm the proposed approach, we have resolved three issues： rotation, scaling and translation invariants. The result of experi- ments shows that the 3DSRSLMs and 3DWRSLMs have done better than the 3D radial complex moments with and without noise. Sim- ultaneously, the reconstruction converges rapidly to the original image using 3D radial 3DSRSLMs and 3DWRSLMs, and the test of 3D images are clearly recognized from a set of images that are available in Princeton shape benchmark （PSB） database for 3D image.

Spot urinary sodium for assessing dietary sodium restriction in cirrhotic ascites

引用

World Journal of Gastroenterology 2009年第29期15卷 3631-3635页

作者： Mohammed Abdelhamid el-Bokl Bahaa eldeen Senousy Khaled Zakaria el-Karmouty Inas el-Khedr Mohammed Sherif Monier Mohammed Sherif Sadek Shabana hassan Shalaby Department of Gastroenterology and Hepatology Ain Shams University school of Medicine Abbassia 11566 Cairo Egypt

AIM： To evaluate the accuracy of spot urinary Na/K and Na/creatinine （Cr） ratios as an alternative to 24-h urinary sodium in monitoring dietary compliance in patients with liver cirrhosis and ascites treated with diuretics. METHODS： The study was carried on 40 patients with liver cirrhosis and ascites treated with diuretic therapy. Patients were divided into two groups according to 24-h urinary sodium. We measured spot urine Na/K ratio, Na/ Cr ratio and 24-h urinary sodium. Student＇s t test was used to compare the interval variables and x^2 test to compare the nominal variables between the two groups. Receiver operator characteristic curve was used to identify the best cutoff point for Na/K and Na/Cr ratio. RESULTS： The best cutoff point for Na/K ratio was 2.5 （P 〈 0.001） and area under the curve （AUC） was 0.9, and for Na/Cr ratio, the best cutoff point was 35 （P 〈 0.001） and AUC was 0.885. Na/K ratio showed higher sensitivity and accuracy compared to Na/Cr ratio （87.5% and 87% for Na/K ratio; 81% and 85% for Na/Cr ratio, respectively）. CONCLUSION： Spot urine Na/K ratio has adequate accuracy for assessment of dietary sodium restriction compared with 24-h urinary sodium in patients with liver cirrhosis and ascites.

Maternal-Fetal Hepatitis E Transmission:Is It Underestimated?

引用

Journal of Clinical and Translational Hepatology 2014年第2期2卷 117-123页

作者： Maysaa el Sayed Zaki Mohammed Magdy Abd el Razek hassan Magdy Abd el Razek Clinical Pathology Mansoura Faculty of Medicine Egypt Mansoura University Hospital Egypt

Hepatitis E virus (HEV) is an enterically transmitted virus;and several modes of transmission have been proposed, including blood transfusion, person to person transmission, and transplacental transmission. HEV during pregnancy is asso-ciated with an unfavorable prognosis for mothers and in severe cases can cause acute fulminate hepatitis and death. Transplacental transmission of HEV usually results in unfa-vorable outcomes of pregnancy, mainly fetal loss, preterm labor, and hepatic dysfunction in neonates. In this review, we will summarize the effects of HEV on maternal-fetal health in various clinical situations.

Micropunch grafting for healing of refractory chronic venous leg ulcers

Chinese Journal of Plastic and Reconstructive Surgery 2022年第4期4卷 166-170页

Background: Chronic venous ulcers are a serious problem for both patients and physicians. The CEAP classification(clinical manifestations(C), etiologic factors(E), anatomic distribution of disease(A), and underlying pathophysiologic findings(P)) for chronic venous disorders(CVD) was developed in 1994. Published papers on CVD use all or part of the CEAP. Micropunch grafts, which are a variation of skin grafts, have been used with great success in plastic surgery for both esthetic and reconstructive purposes. This study aimed to assess the outcomes of micropunch grafting in the treatment of chronic refractory venous ***: Patients with chronic venous ulcers who did not respond to conservative treatment for more than 6months were included in the study. All patients underwent ulcer coverage by micropunch skin grafts using a micrometer. The patients were discharged on the same day as the surgery. Micropunch skin grafts were manually counted per square centimeter intraoperatively and during follow-up using Dermlite DermatoschopeTM II Pro *** satisfaction was assessed by using a ***: Twenty patients underwent the surgery. Most of the patients were middle-aged males. The ulcers were predominantly small-and medium-sized. The mean operation time was 167.00 ± 86.01 min. After 6 months, the survival rate of the planted micrografts was 84%. Three ulcers had graft loss and two patients had an infection at the ulcer site, which was managed conservatively. The patients were followed-up for 14 ***: Micropunch grafting is a useful and convenient method for the treatment of difficult venous ulcers and can be performed on an outpatient basis.
