This study was conducted to investigate the effects of poultry manure (PM) and its derived biochars on chemical properties of a sample calcareous soil. Poultry manure and its derived biochars at 200(B200), 300(B300) and 400(B400)°C were incorporated with 400 g of soil at 2% level (w/w) and incubated for 150 days. Some chemical properties of soil and bio-availability of some nutritional ingr...
optimization of maintenance resources to maximize the system availability is a major concern in different manufacturing systems. therefore, a lot of effort is put to construct optimization models to reach the maximum availability level and to reduce the costs of lack of availability. however, despite these efforts, data uncertainty in the real world problems was neglected in proposed models whi...

background: formalin is an aqueous solution of formaldehyde. it is a protoplasmic poison and causes coagulation necrosis and tissue fixation. case: a 19-year-old girl was brought for autopsy to the mortuary of jss medical college, mysore. conclusion: formalin is an unusual poison to be ingested for suicidal purposes due to selective availability and its strong taste and odor.
background: in the recent years nanostructured materials have been the focus of researches due to their wide-spread possibilities to provide new shapes and structures for some materials. microemulsions can provide uniform nano-sized droplets for templating. microemulsions are isotropic, thermodynamically-stable systems of oil, water and surfactant with a 20-200 nm droplet size. they can be prep...
