Research on Fire Behavior of Ship Engine Room

Research Article of American Journal of Basic and Applied Sciences Research on Fire Behavior of Ship Engine Room Chen keye College of Ocean Science and Engineering, Shanghai Maritime University, Shanghai 201306, China. Due to the need for high performance and reduced commercial cost of ownership, and due to many outstanding advantages such as high strength and light weight, steel has been widely used in engineering practice. In the case of fire, in order to prevent and protect these structures, it is the key issue to study the fire behavior environment. The engine room is also the source of power for ships. It is a high-risk area with frequent fires. Therefore, this paper mainly uses FDS to conduct numerical simulation research through a scaled-down engine room with a size of 3m×3m×3.5m. The change of temperature, pressure and smoke movement in the closed cabin with time at a fire source height of 1.5m is studied. The research shows that the fire behavior inside the closed cabin conforms to the two-zone model, and the fire suppression method of the closed fire has its significant advantages, And looked for the best time to reopen the cabin and the location of subsequent repair structures.

Apiculture Constraints and Opportunities in Diga and Wayu Tuka Districts

Research Article of American Journal of Basic and Applied Sciences Apiculture Constraints and Opportunities in Diga and Wayu Tuka Districts Amsalu Arega1, Hailu Mazengia2 and Muse Haile melekot2 1Bako Agricultural Research Center 2Bahirdar University, College of Agriculture and Environmental Science The study was conducted in Diga and Wayu Tuka Districts to determine the constraints and opportunities of beekeeping. Questionnaire surveys was administered to 146 beekeepers (97.1% males). Majority of the respondents started beekeeping after 2010 (28.03%) by catching colonies as honey bee colony source (54.8%). The major dearth period of the area was late march to early may. The trend of beekeeping in the study area was shifting from traditional to modern beekeeping and the trend of honeybee colony and its yield was decreasing due to honeybee health problem of the area (pests, predators, pathogenic disease, high cost of bee equipment and agrochemical application). In the study area the major pests and predators considered as challenges were ants, beetles, wax moth, varroa destructor and some predators like honey badgers, honeybee eater birds, dead head hawks moth, lizards, wasps and birds respectively. For the reason of time restraint in this study area, farther study on the driving force of challenge and opportunity of beekeeping is suggested by monitoring throughout the year.

Optimization of overhaul of EMU Based on Planning Model

Research Article of American Journal of Basic and Applied Sciences Optimization of overhaul of EMU Based on Planning Model Yu Cao1*, Hairui Zhang1, Zhong Zheng2 1College of Science, China Three Gorges University, Yichang, 443002, China. 2College of Electrical Engineering & New Energy, China Three Gorges University, Yichang 443002, China. With the speed increase of the railway and the construction of the passenger dedicated line, the application efficiency and maintenance quality of the EMU, as the main means of transport of the passenger dedicated line, are directly related to the safe operation of the passenger dedicated line. Therefore, it is very necessary to carry out high-efficiency and high-quality maintenance work for EMU. In this paper, the maintenance problem of EMU is studied. According to the different maintenance process of EMU under different conditions, a mixed nonlinear programming model is established, and the software is used to solve the shortest total time of maintenance of all EMU is 541 min. The model provides a reference for the optimization of maintenance of EMU in actual production and life, and is helpful to improve the maintenance efficiency of EMU.

Research Article of American Journal of Basic and Applied Sciences COMPLIANCE AND DOSAGE FORM PREFERENCE IN IRON/ FOLIC ACID SUPPLEMENTATION IN ANTENATAL CARE MOTHERS, AYDER COMPREHENSIVE SPECIALIZED HOSPITAL, NORTHERN ETHIOPIA: A CROSS SECTIONAL STUDY Teshome Abegaz, Arega Gashaw School of Public health, Mekelle University Background: Globally, iron deficiency anaemia is one of the major health problems of pregnant women. Less than one percent took iron supplements during their last pregnancy, and the major problem with iron-folate supplementation during pregnancy is non-compliance. Objective: The aim of this study is to assess prevalence of Compliance and Dosage Form Preference in Iron folic acid supplementation (IFAS) in Antenatal Care (ANC) visit others, Ayder Comprehensive Specialized Hospital, Ethiopia. Methods: A cross sectional study was conducted at Ayder comprehensive specialized hospital antenatal care from Oct.2018 – Feb.2019. Result: The total number of study participants was 278 and 172 (63.3 %) were in compliance with iron / folic acid supplementation. The five associated variables indicated significant association at 95% confidence interval for compliance to iron/folic acid supplementation was, age less than 28 years AOR=.044, [.015-.128] , a monthly income AOR=10.304, [3.220-32.970] family size AOR=.144 [.036-.565], four and more ANC visits AOR=4.193, [1.689-10.411, first trimesters and second trimester AOR=21.168, [6.297-71.158] and AOR=4.458, [1.592-12.485] , AOR=4.193, [1.689-10.411] all with p value < 0.05. Conclusion: In this study, compliance with prenatal iron folate supplementation remains very poor as 63.3%. Mother’s age, monthly income, number of ANC visits, family size and trimesters have been found to be significantly correlated with compliance during pregnancy with prenatal iron foliate supplementation. Therefore, during the ANC visit health workers and health extension workers must regularly advise on IFAS benefits to strengthen adherence to IFAS during current and future pregnancies. For the implementation and refinement of iron supplementation program strategies and acceptable dosage forms, more ...
