Objective:The Study aimed to develop a rapid inexpensive and simple method for preliminary isolation and detection of *** from clinical *** to probe the impact of deteriorating health measures on the pulmonary tuberculosis control program in Basra ***:A simple monophasic-diphasic setup (MDCS) was used for the isolation and preliminary identification of *** setup consists of a slanted Lowenstein-Jensen medium,the bottom of it is covered with 1 mL of tuberculosis broth thus establishing a diphasic solid liquid environment at the bottom of the screw capped test tube and above them a monophasic ***:During 7 months period from the beginning of December 2003 to the end of June 2004,1 295 cases were managed in Tuberculosis and Chest Diseases Clinic in Basra *** 348 cases were diagnosed as active pulmonary *** consist of 232 new cases and 116 previously registered *** MDCS method showed higher recovery of isolation rate of ***(92.3%) than Lowenstein-Jensen,and pyruvate methods with 78.1%and 51.9%*** this method revealed more rapid appearance of results of 12 days than Lowenstein-Jensen,and pyruvate media with 22 days and 23 days respectively by the traditional culturing *** the study revealed that drug resistance against one or more anti tuberculosis drugs was 23.1%for new cases and 70.8%for the old *** drug resistance accounts for 20%of total isolates from old *** was based on using the critical concentration and 1%proportional *** was more common among males than females with 69.4%and 30.6%respectively. A significant correlation(P<0.05) was found between the productive age group(25-54) and incidence of tuberculosis. Tuberculosis was higher among married(83.8%) than unmarried peoples(22%).Children,husbands and wives showed higher infection rates than others indicating kinship *** of treatment was highly

Effects of magnetic Reynolds number on swimming of gyrotactic microorganisms between rotating circular plates filled with nanofluids

引用

Applied Mathematics and Mechanics(English Edition) 2020年第4期41卷 637-654页

作者： Lijun ZHANG M.B.ARAIN M.M.BHATTI A.ZEESHAN H.Hal-sulami College of Mathematics and Systems Science Shandong University of Science and Technology Nonlinear Analysis and Applied Mathematics (NaaM)-Research Group Department of Mathematics Faculty of Science King Abdulaziz University Department of Mathematics and Statistics International Islamic University

The three-dimensional(3D) nano?uid ?ow among the rotating circular plates ?lled with nanoparticles and gyrotactic microorganisms is studied. A generalized form of the magnetic Reynolds number is used for the mathematical modeling of the ferro-nano?uid ?ow. The torque e?ects on the lower and upper plates are calculated.A di?erential transform scheme with the Pad′e approximation is used to solve the coupled highly nonlinear ordinary di?erential equations. The results show that the squeeze Reynolds number signi?cantly suppresses the temperature, microorganism, and nanoparticle concentration distribution, and agree well with those obtained by the numerical method.
