s The purpose of this study was carried out by the embryotoxicity risk assessment of the dental alloys containing indium. We produced Ag-In alloy, Ag-Pd-Au-Cu alloy and gold alloy for porcelain bonding. For the extraction of these alloy components into the ES-D3 cell culture medium, each alloy was reduced to a powder using a diamond point and sterilized after rinsing. In order to facilitate the...

We examine predicative adjectives as an unsupervised criterion to extract subjective adjectives. We do not only compare this criterion with a weakly supervised extraction method but also with gradable adjectives, i.e. another highly subjective subset of adjectives that can be extracted in an unsupervised fashion. In order to prove the robustness of this extraction method, we will evaluate the e...

Pyrite and arsenopyrite are known to be the most common gold-bearing sulfide minerals in refractory gold ores. Traditionally, these have been first oxidized by roasting, acidic pressure oxidation or bio-oxidation release gold, after which is dissolved subsequent cyanide leaching step. The chloride (chloride-bromide) solution presents an alternative cyanide-free media, able not only leach minera...

The material on the gold content of coastal-marine deposits western coast Kamchatka is analyzed and resource potential briefly characterized. A review technological estimates obtained from study gold-bearing samples taken in promising areas strip, Bolshaya Vorovskaya River north to Cape Levashova south, presented. Stock materials supplemented by our studies were used. Gold-bearing with very fin...

Contamination of water from nanomaterials will be an emerging problem in the future due to incorporation of nanomaterials in many commercial products and improper disposal of waste materials. In this report, electrospun polyvinyl alcohol nanofibers (PVA NFs) with diameters ranging between 300 and 500 nm were used for the extraction of nanosized contaminants from the aqueous environment. To obta...
