Pateyar antimony ore deposit is located 13 km northeast of Anarak. From geological aspect the ore deposit is part of the upper Anarak metamorphic cover ling Chah - Gorbeh and Morghab complexes.These rocks have Late Proterozoic age. The ore deposit is composed of metamorphic, igneous and sedimentary rocks.This area is tectonically very active. The antimony minerals associated with quartz (as a gaunge), are concentrated as vein in fault contact zones.Arsenic, gold, Silver, copper and molybdenum are associated with antimony study in this paper.A high correlation is observed between antimony and arsenic elements. Based on geochemical studies and fabric evidences, pateyar antimony deposit is formed in two stages. At first stage, ore minerals associated with detrital sediments is precipitated and in the second stage, mobile elements from country rock during metamorphic activities are concentrated in faults and open spaces and is enriched by ore minerals.

Abstract: Antimony mineralization occured in Hamedan district (Faghireh) which is related to Alvand Granitoids. The mineralization occured as a series of veins. Thickness of veins are variable and reach up to 0.7m. The veins are emplaced along high angle faults. These faults acted as a pathway for migration of ore fluids. Veins are composed of stibnite, pyrite, realgar and orpiment with quartz as a gangue. The textures of veins are open space filling, however brecciations also occured. Monzogranites, which formed the main part of Alvand pluton, is the host of quartz - stibnite veins. Monzogranites are composed of quartz, sodium plagioclase (oligoclase), orthoclase, biotite and sometimes muscovite.The veins are composed of 30.5% antimony, 0.83 ppm gold and 498 ppm arsenic. Based on geochemical studies, Sb, Au, AS, Ag, Hg, Sn, Ni, Co and Cr contents of host rocks are much higher than the world's average monzograniets and have probably anomalies. Spiderdiagrams show an identical pattern for host rocks and veins, which strongly suggests that these veins are cogenetic with the intrusive rocks (monzogranite).In summary, with all geological evidences in the region, it can be concluded that the mineralization is probably occured in the epithermal type.

Acute cutaneous Leishmaniasis (ACL) is an endemic disease in developing countries. The first line drug for treatment of ACL, according to WHO recommendation, is the pentavalent antimony compounds such as meglumine antimonite (Glucantime [sb]). High cost, side effects, multiple injections and incomplete efficacy are limitations of this therapy. We evaluated the efficacy of intralesional (IL) injection of Zinc sulfate 2% in treatment of ACL and compared that with efficacy of IL injection of Glucantime (sb). This prospective double-blind case control clinical trial was performed on 104 patients with typical lesions of ACL and positive direct smear. These patients were treated by IL injection of contents of one of two similar vials A or B. The vials were coded by an independent physician. The patients were seen in two weeks intervals and injection was repeated when required. Improvement was evaluated by clinical examination and direct smear. Follow-up period was six weeks. 66 patients were followed until 6 weeks (35 patients from A group and 31 from B group). After 6 weeks, the cure rates were 60% for A solution and 83.87% for B solution. After 2,4 and 6 weeks of treatment, the responses to therapy with A solution were respectively 3.5±1.14, 3.68±1.11 and 3.8±1.05 versus 3.84±1.11, 4.6±1.25, 3.85±1.24 for B solution. After second and forth weeks, the efficacy of treatment with B solution was higher than A solution (P<0.01), but after six weeks no significant differences were observed between two groups (P>0.05). After only one injection of B solution, cure rate was 54.84%. Reinjection significantly increased efficacy of A, but not of the B solution. A solution was Glucantime and B solution was Zinc sulfat 2%. On the basis of this trial, treatment of ACL by intralesional injection of Zinc sulfate 2% maybe effective.

In this research the best conditions of biosorption of Sb III and Sb V were studied by using of Saccharomyce cerevisiae. This is a cheap, non-toxic yeast and available at stores.Biosorption of solution of 2.5ppm of antimony at 60 C and after 30 minutes is the best condition.Maximum of biosorption is at pH 3 for Sb III (%90±%3) and minimum at pH 10 is 20±%4. for Sb V maximum of biosorption at pH 10 is 5%±%3 and at pH 3 is 35±%4. At pH 7 bisorption of Sb III is %80±%3 and fr Sb V is %20±%2. Species were measured with ICP-AES.

Thin film thermopiles are widely used as small size sensors, in particular to sense infra-red thermal radiations. In this paper a method for designing and fabrication of thin films Bi-Cu thermopiles in linear array of 8 and 11 elements in series and mono-layer is introduced. Also, fabrication of Bi-Sb and Bi-Cu thin film thermopiles, which are used as IR radiation sensors, made in multilayer form with 100 series junctions in circular shape are presented. The samples are fabricated on a PCB board with double-sided copper laminated as a substrate. The results of our measurements show that the output voltage produced due to temperature difference between junctions, is very sensitive and linear to temperature difference
