BACKGROUND & OBJECTIVES Sensitivity of Ziehl-Neelsen (ZN) method is known to be low for liquefied sputum smears. Information on the ZN sensitivity for centrifuged deposit smears is not known. This study was carried out to determine the sensitivity of ZN method for acid fast bacilli (AFB) in centrifuged deposit smears and liquefied sputum smears made from sputum samples transported in cetyl-pyri...

The Kangjiawan deposit, in the Shuikoushan district, Hunan Province, China, is a representative hydrothermal Pb–Zn–Ag– Au deposit in this region. The orebodies consist mainly of pyritic Pb–Zn ores. Silver minerals are associated with Pb–Zn mineralization. Ag-bearing Pb–Zn ores in the deposit are characterized by Ag > Cu > Sb content. Silver occurs mainly as silver minerals, such as minor argent...

BACKGROUND & OBJECTIVES Making centrifuged deposit smears from sputum to detect acid-fast bacilli (AFB) is considered hazardous. We carried out this study to stain the centrifuged deposits with carbol-fuchsin in sputum containers and to decolourize and counterstain their smears made on glass slides. METHODS The centrifuged deposits of 180 sputum samples from pulmonary tuberculosis patients we...

taknar polymetal (cu-zn-au-ag-pb) deposit: a new type magnetite-rich vms deposit, northeast of iran

pb-zn deposits in the kurdistan region, northern iraq, have occurred mainly as a stratabound and open-space filling ore bodies. they are hosted by dolostone and dolomitic-limestone of platform carbonates. the ore deposits at the studied dure and lefan areas are respectively hosted by kurra chine (upper triassic) and bekhme (upper cretaceous) formations. pyrite, sphalerite and galena are the maj...

Taknar Polymetal (Cu-Zn-Au-Ag-Pb) Deposit: A New Type Magnetite-Rich VMS Deposit, Northeast of Iran

A cooperative behavior of Zn(2+) and Li(+) to conduct charges in a Zn-LiFePO4 battery is disclosed. When Li(+) dissolves into the electrolyte, Zn(2+) would deposit, and vice versa. In light of this cooperative behavior, the battery can be viewed as a super hybrid system, which combines the strong points of Zn-air battery, lithium-ion battery and redox-flow cell.

Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...

Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...
