the cheshmeh hafez polymetal deposit is located in troud – chahshirin mountain range in southeastern damghan. in this province, the volcanism and associated mineralization are closely related to major faults anjilo and troud with nw-se trend. the exposed rocks in the study area consist of volcano clastic sequence of sandstone, tuff, volcano breccias and mostly andesitic and andesitic- basalt fl...

Hydrogels are an important class of highly hydrated polymers that are widely investigated for potential use in soft tissue engineering. Generally, however, hydrogels lack the ability to mineralize, preventing the formation of chemical bonds with hard tissues such as bone. A recent trend in tissue engineering involves the development of hydrogels that possess the capacity to mineralize. The stra...

The growing interest in Ghana’s gold mining sector due to the recent upsurge in the price of gold has impacted greatly on the economy of the country with regard to its revenue generation capacity. There is therefore the need to develop this sector. Hence, any new method which is relatively low cost and has comparable efficiency compared to prevailing conventional methods in delineating new pote...

The functional response to and recovery from coal-coking waste effluent was evaluated for sediment microbial communities. Twenty estimates of microbial population density, biomass, and activity were measured five times during a 15-month period. Significant effects on microbial communities were observed in response to both wastewater contamination and diversion of the wastewater. Multivariate an...

Accelerated bleaching, photobleaching and mineralization of the non-biodegradable azo-dye, Orange II, was observed with oxone in solutions with Co2+-ions. The bleaching rate of Orange II in the dark was found to follow a first-order kinetics with respect to [Co2+] with a rate constant of 20 M−1 s−1. Fitting of the Orange II photobleaching experimental points in the presence of the Co2+/oxone re...

The influence of sedimentation rates on biogeochemistry of riparian forests was studied near ephemeral streams at Fort Benning, GA. Upper reaches of seven ephemeral streams had received varying rates of sedimentation stemming from erosion along unpaved roadways at the military installation. Two reference catchments were also included in the study. Decomposition of foliar litter, microbial C and...
