Health Factors in Islamic Perspectives and its Relation to Sustainability with Case Study at Traditional and Modern Mosque

The study elucidates how health consideration integrated to the traditional, conventional and modern mosque design in Bangladesh. A literature survey is conducted to understandard the definition of health based on Islamic perspective. The purpose is to compare its sustainability and relationship with traditional and present design pattern of mosque. The literature study identifies four primary factors on health in the mosque design associated with natural lighting, ventilator, location of toilets and rainwater discharge. Analysis comprises design on natural lighting related to sun shading and indirect lighting, rainwater discharge related to rainwater deflection and leakages and wall openings related to natural cross air ventilation. In this study, Kalitikor Central Mosque, Bandar based on traditional pattern, Noyashorok Jamia Mosque and Amborkhana Jamia Mosque were chosen as modern type mosque. The analysis however shows the weakness that Kalitikor Central Mosque and Amborkhana Jamia Mosque design does not apply enough windows in the construction for opening furthermore Amborkhana Jamia Mosque design includes toilet facilities within the mosque. Noyashorok Jamia Mosque have sufficient opening in Back and left side however Amborkhana and Nayashork both of the mosque have no open windows facilities in it’s right hand side. The traditional toilet system is also a threat to health and safety factor. DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11547 J. Environ. Sci. &amp; Natural Resources, 5(1): 01-08, 2012</jats:p

Study of sorption of 2,4-d on outer peristaltic part of waste tire rubber granules

From this study it was evident that outer peristaltic parts of waste tire granules gave the highest removal. Film and pore diffusions are the major factors controlling rates of sorption from solution by porous adsorbents. For sorption of 2,4-D on waste tire rubber granules, the sorption rate coefficient of second-order kinetic equation was utilized indirectly to determine the rate-limiting step. The diffusion coefficient lies in the scale of 10(-8)cm(2)/s, and the pore diffusion coefficient is in the range of 10(-9) -10(-1)0cm(2)/s. So both film and pore diffusion are rate limiting. Considering external mass transfer from fluid to particle, using the effect of initial concentration, and using the effect of adsorbent size, no conclusion was reached regarding rate-controlling steps. It is apparent from the study that external mass transfer (film diffusion) as well as intra-particle diffusion (pore diffusion) play significant roles in the sorption process for 2,4-D removal from water onto rubber granules
