Reducing Earthquake Fatalities and Destructions in Iran: A Project Management Perception
Amin Akhavan Tabassi,Abu Hassan Abu Bakar,Nor'Aini Yusof 한국유통과학회 2014 Asian Journal of Business Environment (AJBE) Vol.4 No.1
Purpose – Appropriate project management knowledge as well as its effective application in the construction industry increase construction quality and, therefore, reduce fatalities and destruction. Research design, data, and methodology – This study was conducted through a comparative analysis of earthquake fatalities in Iran, Turkey, Pakistan, Indonesia, China, Haiti, Japan, and the United States of America. The data was analyzed using a frequency study. The analysis contrasts the fatalities of some of the strongest earthquakes around the world between 1960 and 2010. Results – Poor quality construction practices and a lack of effective application of project management knowledge play a major role in the vast destruction, high death toll, and dismal tragedies that are associated with earthquakes, especially in Iran. Conclusions – Despite the history of tragic earthquakes and their continuing recurrence, this study attempts to make governments, companies, and disaster management personnel aware of the dangers of poor quality construction and the deficient application of project management knowledge and, further, accentuates effective ways to prevent the probability of serious damage in future. This study contains valuable information on the effects of project management application towards reducing earthquake fatalities and destruction.
Temperature effect on spherical Couette flow of Oldroyd-B fluid
Hassan, A. Abu-El,Zidan, M.,Moussa, M.M. The Korean Society of Rheology 2007 Korea-Australia rheology journal Vol.19 No.4
The present paper is concerned with non-isothermal spherical Couette flow of Oldroyd-B fluid in the annular region between two concentric spheres. The inner sphere rotates with a uniform angular velocity while the outer sphere is kept at rest. Moreover, the two spherical boundaries are maintained at fixed temperature values. Hence, the fluid is effect by two heat sources; namely, the viscous heating and the temperature gradient between the two spheres. The viscoelasticity of the fluid is assumed to dominate the inertia such that the latter can be neglected. An approximate analytical solution of the energy and momentum equations is obtained through the expansion of the dynamical fields in power series of Nahme number. The analysis show that, the temperature variation due to the external source appears in the zero order solution and its effect extends to the fluid velocity distribution up to present second order. Viscous heating contributes in the first and second order solutions. In contrast to isothermal case, a first order axial velocity and a second order stream function fields has been appeared. Moreover, at higher orders the temperature distribution depends on the gap width between the two spheres. Finally, there exist a thermal distribution of positive and negative values depend on their positions in the domain region between the two spheres.

Hassan, Muhammad Radzi Abu,Suan, Mohd Azri Mohd,Soelar, Shahrul Aiman,Mohammed, Noor Syahireen,Ismail, Ibtisam,Ahmad, Faizah Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.7
Background: Cancer survival analysis is an essential indicator for effective early detection and improvements in cancer treatment. This study was undertaken to document colorectal cancer survival and associated prognostic factors in Malaysians. Materials and Methods: All data were retrieved from the National Cancer Patient Registry-Colorectal Cancer. Only cases with confirmed diagnosis through histology between the year 2008 and 2009 were included. Retrieved data include socio-demographic information, pathological features and treatment received. Survival curves were plotted using the Kaplan-Meier method. Univariate analysis of all variables was then made using the Log-rank test. All significant factors that influenced survival of patients were further analysed in a multivariate analysis using Cox' regression. Results: Total of 1,214 patients were included in the study. The overall 3- and 5-year survival rates were 59.1% and 48.7%, respectively. Patients with localized tumours had better prognosis compared to those with advanced stage cancer. In univariate analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p=0.001) were found to be predictors of survival. None of the socio-demographic characteristics were found to exert any influence. In Cox regression analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p<0.001) were determined as independent prognostic factors of survival after adjusted for age, gender and ethnicity. Conclusions: The overall survival rate for colorectal cancer patients in Malaysia is similar to those in other Asian countries, with staging at diagnosis, primary tumor size, involvement of lymph node and treatment modalities having significant effects. More efforts are needed to improve national survival rates in future.

Background: A colorectal cancer screening program was piloted in two districts of Kedah in 2013. There is scarcity of information on colorectal cancer screening in Malaysia. Objective: Thus, this research was conducted to evaluate the colorectal cancer screening program in the districts to provide insights intop its efficacy. Materials and Methods: A cross sectional study was conducted using data on the colorectal cancer screening program in 2013 involving Kota Setar and Kuala Muda districts in Malaysia. We determined the response rate of immunochemical fecal occult blood test (iFOBT), colonoscopy compliance, and detection rates of neoplasia and carcinoma. We also compared the response of FOBT by demographic background. Results: The response rate of FOBT for first iFOBT screening was 94.7% while the second iFOBT screening was 90.7%. Participants from Kuala Muda district were 27 times more likely to default while Indians had a 3 times higher risk of default compared to Malays. The colonoscopy compliance was suboptimal among those with positive iFOBT. The most common finding from colonoscopy was hemorrhoids, followed by tubular adenoma. Detection rate of carcinoma and neoplasia for our program was 1.2%. Conclusions: In summary, the response rate of iFOBT was encouraging but the colonoscopy compliance was suboptimal which led to a considerably low detection rate.

<P><B>Abstract</B></P> <P>Previous studies on solution concentration, density, coating time, and annealing temperature of sol-gel ZnO seeds have underrated the growth of ZnO nanostructures. However, these details are quite vital and central to growth of vertically aligned ZnO nanorods (ZNRs). The current study investigates ZNR structure and growth dependence upon solution concentration, thickness, density, diameter, annealing time, annealing temperature, and crystalline quality of sol-gel spin coated ZnO seeds. For growth optimization, we used 0.02, 0.04, and 0.09 M zinc acetate seeds in n-propanol coated two and five times on a p-Si substrate. We found that seed thickness and density depend upon successive coats and the seed solution concentration. The morphology, alignment, density, aspect ratio, crystalline quality, and optical properties of ZNRs are directly related to the seed parameters. The defect centers in seeds and ZNRs are independent of each other. We also studied the electrical characteristics of spin coated seeds, which is a hallmark in the research and development of seed oriented growth of ZnO nanostructures.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Structural, optical, electrical, and morphological properties of different concentration sol-gel ZnO seeds are presented. </LI> <LI> The ZnO nanorod (ZNR) growth depends upon the concentration, thickness, and crystalline quality of seeds. </LI> <LI> The ZNR structural and optical properties confide in the structural and optical properties of seeds. </LI> <LI> The seed layer defect density and carrier concentration are directly proportional to seed solution concentration. </LI> <LI> Annealing temperature and time are of paramount importance in seed layer stability. </LI> </UL> </P>
