according to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. the low value residual gold ions existed in acid leaching tail solution in mouteh gold mine in iran with fellow heavy metals as pollutants (fe2+, cu2+, and zn2+). preparation of nano gold particles is achieved by two steps: first, by addition of ammonia as separatio...
the aim of the study is to determine the major source and extent of metal pollution in the vicinity of dashkasan gold mine. dashkasan mine has resulted in extensive contamination of soils by arsenic (as) and potentially toxic ore-related elements including mercury (hg), antimony (sb) and cadmium (cd). soils samples were collected and analyzed for as, cd, hg, pb and sb. the concentration of each...
objective(s): abdominal adhesions are one of the most important problems, occurring after intra-abdominal surgery in more than 90% of cases. this condition is the leading cause of bowel obstruction, infertility, and abdominal/pelvic pain. gold nanoparticles (gnps) have been shown to be non-toxic and exhibit anti-inflammatory, anti-angiogenic and antioxidant activities. the purpose of this study...
background: radiation-sensitive polymer gels are among the most promising three-dimensional dose verification tools and tissue-like developed to date. among the special features of this type of dosimeters, is be doped with other elements or chemicals which made them appropriate for investigating of dose enhancement with contrast agents, by high atomic number. material and methods: in this study...
background: the study was aimed to explore the association between arterial oxygen saturation (spo2) and spirometer parameters of disease severity in copd patients with a view to identify whether the pulse oximetry can be used as an alternative to arterial values in the clinical management of copd patients in a routine practice. materials and methods: thirty-one patients with copd were included...
The Chah-Bagh gold occurrence is located in Muteh mining district, in the central part of the Sanandaj-Sirjan zone. Gold mineralization occurs in ductile to ductile-brittle shear zones and is comparable with orogenic gold deposits. Silicification and sulfidization are the most important hydrothermal alteration features in the inner parts of altered shear zones and coincide most closely with the...

Background and purpose: Synthesis of homogeneous and equally important nanoparticles is very popular in various sciences. Preparation and use of gold nanoparticles is very important according to their applications in biotechnology. For synthesizing homogeneous gold nanoparticles many substrates and nanostructures have been used. This study aimed at synthesis of gold nanoparticles by apoferriti...
Hedging is one of the most important topics in investment field, which could be noticed from different points of view. We evaluate the role of gold relative to different indices in Tehran Security Exchange (TSE) as a representative of Iran Capital Market .In this topic gold charecterristics of “save haven” and “hedge” versus TSE are studided. Daily Price Returns of 21 TSE stock indices and dail...
