Reprocessing tailings for gold recovery is generating new low-grade refractory secondary tailings. Unlocking trapped within these potentially holds additional economic value. In this study, the use of supercritical carbon dioxide (scCO2) at 100 bar and 40 °C extraction from such a sample (0.27 g Au/t) was investigated. The research identified screened following ligands as suitable extractants i...

This year marks the fiftieth anniversary of first implant an inflatable penile prosthesis (IPP). The authors this paper want to celebrate event with a narrative review current literature. main scopes are antibiotic prophylaxis, patient satisfaction, and future developments. IPP in 1973, performed by Branteley Scott was turning point history prosthesis, revolutionizing treatment erectile dysfunc...

Breathlessness is a distressing symptom, uniformly faced at some point in the disease process all patients with Chronic Obstructive Pulmonary Disease (COPD). Despite maximal medical therapy and pulmonary rehabilitation, COPD continue to experience refractory dyspnea, pain, poor appetite, limitations of physical activity, emotional distress, depression overall health-related quality life. Our cu...

objective the lennox-gastaut syndrome (lgs), one of the most difficult epilepsy syndromes to treat, is characterized by a triad of intractable seizures of various types, a slow (< 2.5-hertz) spike-wave pattern in eeg and mental retardation. the aim of this study was to evaluate the efficacy and safety of lamotrigine as add-on therapy in intractable epilepsy of children with lgs. materials & met...

objective midazolam is a significant and effective drug for control of a life-threatening condition, generalized and partial refractory convulsive status epilepticus. the goal of this study was evaluation of midazolam efficacy for management of this serious disease and its two side effects, hypotension and respiratory failure. materials & methods our study was done using a quasi experimental me...

we discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. th e most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. moreover, since the systemic involvement of the di...

Since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. After gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, One of these methods is activated carbon.The loading of gold from industrial thiosulfate solut...
