The orthogonal array design has been used to determine the optimum conditions for gold recovery from Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation. The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore . T...

Phytoremediation is the technique based on the use of plants to remediate sites contaminated with organic and inorganic pollutants. This technology is rapidly growing as is helpful to growing industries. Colocasia esculenta is a tropical plant grown primarily for its edible corm and the root vegetables. It has many names like Taro and Eddoe. It is a wide spread emergent aquatic plant, generally...

The recycling of organic wastes is required from the viewpoint of environmental issues. Sewage sludge makes up about 30% of the organic wastes in Japan, and at present, the ratio is increasing (Study group on bio-waste recycling, 1999); therefore, it is important to treat and utilize the sewage sludge. Conventional treatment methods such as land filling and ocean dumping have been regulated to ...

in order to investigate the effect of municipal solid waste (msw) compost and sewage sludge (ss) on yield and concentration of heavy metals in soil and black cumin (nigella sativa l.) an experiment with msw compost at 0, 15, 30 t.ha-1 (c0, c15 and c30) and sewage sludge at 0, 15, 30 t.ha-1 (s0, s15 and s30) in a factorial experiment based on completely randomized design with three replications ...

Objective To investigate the prevalence of autonomic dysreflexia (AD) using ambulatory blood pressure monitoring (ABPM) and the autonomic dysfunction following spinal cord injury (ADFSCI) questionnaire in patients with spinal cord injury (SCI) above T6. Methods Twenty-eight patients diagnosed with SCI above T6 were enrolled. ABPM and ADFSCI were utilized to assess AD. Using ABPM, systolic blo...

The purpose of this study was to investigate the protective effects of ischemic post-conditioning on damage to the barrier function of the small intestine caused by limb ischemia-reperfusion injury. Male Wistar rats were randomly divided into 3 groups (N = 36 each): sham operated (group S), lower limb ischemia-reperfusion (group LIR), and post-conditioning (group PC). Each group was divided int...

Aquaporin-2 (AQP-2), a water channel located on the apical membrane of collecting duct cells, regulates water reabsorption under the control of vasopressin (AVP). Using an antibody directed to human AQP-2, a quantitative Western blot analysis was performed to determine the collecting duct responsiveness to an oral, nonpeptide, V2 receptor antagonist (VPA-985) in patients with chronic NYHA II an...
