Mammalian prion diseases are fatal neurodegenerative disorders dependent on the prion protein PrP. Expansion of the oligopeptide repeats (ORE) found in PrP is associated with inherited prion diseases. Patients with ORE frequently harbor PrP aggregates, but other factors may contribute to pathology, as they often present with unexplained phenotypic variability. We created chimeric yeast-mammalia...

The chemical and physical composition of the feldsparquartz sand-ore differ from location to location in a given open pit mine mine and the utilisation of the raw-ore, as well as its resale value will depend on these properties. Thus. a very important aspect of the operation is to determine quickly and accurately the properties of the sand at a given location. Laboratory methods are accurate bu...

A significant contemporary challenge for gold mining companies is to define economic process options for treating more complex ore bodies as the less refractory ores become depleted. Demonstration of economic treatment options allows gold companies to maintain and increase their ore reserves. The selection of options to treat a specific ore is significantly impacted by factors such as mineralog...

Su canlı hayatı için en önemli ihtiyaçtır. Birçok endüstriyel ve tarımsal faaliyet suların kirlenmesine neden olmakta, insan çevre sağlığını mutajenik, alerjik, toksik hatta ölümcül boyutta etkilemektedir. Türkiye, 16 Temmuz 2021 tarihinde resmi gazetede yayımladığı bir genelgede sürdürülebilir ekonomik büyümenin iklim değişikliği ile mücadelenin, kaynak-etkin yeşil ekonomiye geçisin adımlarını...

Pseudonannolene spelaea n. sp. is the first strictly cave-dwelling species described for the family Pseudonannolenidae. It is found in iron ore caves in the Brazilian Amazon. The family Pseudonannolenidae is exclusively Neotropical and frequently found in caves of Brazil, from which 20 species are known. The new species is compared with its congeners and with related cave-dwelling species. The ...

In order to simplify the factor which affected on granulation properties of iron ore, experiment was conducted by using nuclei and fine ore having smooth surface. The effect particle size hematite strength investigated. results obtained are follows:

Abstract—Accurately positioning detection of concealed deposits or ore-bodies is one of the difficult problems in mineral exploration field. Theory calculation and exploration practices for tunnel gravity indicate that 3D high-precision Tunnel Gravity Exploration Method (TGEM) can find concealed high-density three-dimensional ore-bodies in the depth. The ore-finding breakthroughs at the depth o...
