The results of the first assessment antimony release into atmospheric air on territory Belarus are discussed. main anthropogenic sources emission have been identified, factors developed, and volumes for period from 1990 to 2020 calculated. It is shown that total emissions varied in range 1.6 5.6 tons per year with maximum values early s, minimal – 2000. Antimony country estimated at 2.4 t, cont...

The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...

1Institute of Endemic Diseases, University of Khartoum, Khartoum, Sudan. ABSTRACT A longitudinal study was done in a leishmaniasis-endemic region in eastern Sudan during the period November 2001–February 2003 to determine the incidence of failure of sodium stibogluconate treatment. We studied 820 confirmed visceral leishmaniasis patients. All were treated with sodium stibogluconate, 20 mg/kg bo...

Nanostructures have the potential to exhibit good thermoelectric properties by tuning and controlling their size and thickness, and the competing electrical and thermal properties can be decoupled by engineering the interface and grain boundary. In the present study, Sb2Te3 nanoplatelets with different sizes were fabricated using a practical solvothermal method. The thickness of the platelets w...

We present a lattice dynamics study of orthorhombic antimony sulphide (Sb2S3) obtained using density-functional calculations in conjunction with the supercell force-constant method. The effect of Born effective charges is taken into account using a mixed-space approach, resulting in the splitting of longitudinal and transverse optical (LO-TO) phonon branches near the zone center. Zone-center fr...

a pentavalent antimony compound with the formula Sb.O-H, C7H170-N, containing 28.35 per cent of antimony. The compound makes a stable watery solution and is supplied in ampoules as a 30 per cent solution. Methyl glucamine antimoniate (MGA) is reported to be of a very low toxicity, the m.l.d. being 30 mg. per 20 gm. white mouse or about 1.5 gm. per kilo. It was found to possess curative action i...
