Let k be a field and X a smooth projective variety of dimension d over k. Generalizing a construction of Kato and Somekawa, we define a Milnortype group Ks(k; CH0(X);Gm) which is isomorphic to the ordinary Milnor K-group Km s (k) in the case X = Spec k. We prove that Ks(k; CH0(X);Gm) is isomorphic to both the higher Chow group CHd+s(X, s) and the Zariski cohomology group Hd Zar(X,K d+s).

Chlorination, ozonation and non-thermal plasma water purification technologies were compared in terms of their effectiveness, efficiency, capital operating costs, energy yield chemical demand. Retrofitting technology to chlorination plants offered the lowest cost (ZAR 14,000 or USD 253,376 based on current South African Reserve Bank rate ZAR/USD 18.0983) most effective contaminant removal (of t...

BACKGROUND This study aims at evaluating the cost-effectiveness of a 2-dose schedule human papillomavirus (HPV) vaccination programme of HPV and human immunodeficiency virus (HIV) naïve 12-year-old girls, in addition to cervical cancer (CC) screening alone, in South Africa. The study aims to account for both the impact of the vaccine among girls who are HIV-positive (HIV+) as well as HIV-negati...

different types of iron oxides deposits have been identified along the khaf – dorouneh volcanic and plutonic belt in north east of iran. kuh-e-zar is one of these ore deposits known as fe- oxide gold deposit. the main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the etm+ data. data processing has been done by envi (environment for visualizing...
