background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...

background recombinant human erythropoietin (rhuepo) treatment can increase hemoglobin levels and decrease transfusion requirements. this study aims to investigate how blood transfusion influences hemoglobin levels in patients receiving rhuepo for 12 weeks. materials and methods this was a case-control study of 60 patients less than 15 years with anemia and a solid tumor in any location between...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

tehran has a population of over 12 million and produces more than 7500 tons of waste every day. tehran’s municipal solid waste is processed and landfilled at kahrizak disposal center. due to inappropriate waste management, a lake with a leachate volume of 180,000m3 has been formed. to solve this problem a leachate treatment plant is currently under construction. a byproduct of leachate treatmen...

a chelating resin is prepared by condensation polymerization of aniline with formaldehyde andcharacterized by ft-ir, elemental analysis and studied for the preconcentration and determination of traceplatinum ion from environmental water sample using inductively coupled plasma-atomic emission spectroscopy(icp-aes). the optimum ph value for sorption of the metal ions was 5. the maximum adsorption...

a study of the biokinetics of anaerobic digestion of municipal solid waste (msw) was carried out using anaerobic batch digester. from the experimental results, the kinetic parameters (coefficient values) of the digestion of the msw were determined. the maximum rate of substrate utilization (k), saturation constant (ks), endogenous decay coefficient (kd), biomass yield or microbial growth yield ...

the present study deals with characterization of dispersions of a poorly water-soluble drug, celecoxib (clx) in polyvinyl caprolactame–polyvinyl acetate–polyethylene glycol graft copolymer (soluplus® (sol)) prepared by different techniques. dispersions of clx in sol at different ratios (2:1, 1:1, 1:2, 1:4 and 1:6) were prepared by spray drying, conventional solvent evaporation and melting metho...

abstract aims: increasing of the population and development of urban areas, has led to solid waste generation increasing which is one of the problems and difficulties that put human and environmental health in danger. the aim of present study was to determine the knowledge and attitude level of kashan university of medical sciences’ students about solid waste recycling. instrument & methods: th...

background : common variable immunodeficiency (cvid) is associated with a broad spectrum of symptoms related to infections, chronic lung diseases, autoimmune diseases, and tumors; however, solid tumors are rare complications of cvid and gastric cancer, specially, has been reported very rarely. case presentation : the present case report describes a 28 years old known case of cvid male, who was ...

We propose a method to predict the value of the external strain where a generic amorphous solid will fail by a plastic response (i.e., an irreversible deformation), solely on the basis of measurements of the nonlinear elastic moduli. While usually considered fundamentally different, with the elastic properties describing reversible phenomena and plastic failure epitomizing irreversible behavior...
