––Estimating local deer populations is an important consideration for deer managers. Shelled corn is commonly used to attract white-tailed deer (Odocoileus virginianus) to infrared-triggered camera survey sites. The addition of mineral formulations may increase deer visitation. We evaluated the effect of four mineral formulations on deer visitation at two study areas in Tennessee. Mineral formu...

Introduction: The discovery of ferric hydroxides/oxyhydroxides, jarosites (iron-bearing sulfates thought to have formed via aqueous activity) and other sulfate-bearing minerals in the Meridiani region provides strong evidence that liquid water once flowed on the Martian surface [1-3]. It is suggested that sulfate deposits enriched in iron and mixed iron oxyhydroxide were precipitated form meltw...

Background. Earlier we showed that the newly created sulfate-chloride sodium-magnesium drinking mineral waters “Myroslava” (5 g/L) and “Khrystyna” (10 have favorable effects on neuroendocrine-immune complex metabolism of patients with their violations. At same time, influence both one constellation parameters is similar, despite twofold difference in mineralization, while other it different. Th...

Sulfur is an essential macronutrient for plant growth and development. Reaching a thorough understanding of the molecular basis for changes in plant metabolism depending on the sulfur-nutritional status at the systems level will advance our basic knowledge and help target future crop improvement. Although the transcriptional responses induced by sulfate starvation have been studied in the past,...

Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

Pore water and sediment geochemistry in the western Black Sea were investigated on long Calypso piston core samples. Using this type of coring device facilitates recovery thick record necessary to analyze transport-reaction processes response postglacial sea-level rise intrusion Mediterranean salt 9 ka ago, thus, better characterize key biogeochemical process changes shift from lacustrine marin...

Sulfur and molybdenum trace impurities in speleothems (stalagmites stalactites) can provide long continuous records of volcanic activity, which are important for past climatic environmental reconstructions. However, the chemistry governing incorporation element-bearing species into calcium carbonate phases forming is not well understood. Our previous work has shown that substitution tetrahedral...

In this article, the efficiency of microwave pretreatment, which is an environmentally friendly, low-energy consuming method for recovery from refractory gold-silver ores, was investigated. The ore sample belonged to oxidized Bolkardağ deposit, contains carbonate (calcite, dolomite, smithsonite, hydrozincite), silicate (quartz, hemimorphite), sulfate (beudantite, plumbo-jarosite), and iron oxy/...
