the aim of this study was to identify various sulfidic mineralized zones in the ghare-tappeh cu deposit (nw iran) based on geo-electrical data including induced polarization (ip) and resistivity (rs) using the concentration-volume (c-v) and number-size (n-s) fractal models. the fractal models were used to separate high and moderate sulfidic zones from low sulfidic zones and barren wall rocks. b...

The chemical composition of amphiboles from granitoid rocks of Selijerd and Neshveh plutons in NW Saveh, Central Iran, are studied for petrogenetic purpuses, tectonomagmatic features and geotermobarometery of these plutons. The chemical composition of these amphiboles falls in the calcic amphibole group and is actinolite to magnasio-hornblende. They are assosiated with the active continental ma...

Gold production in New Zealand has been significant since the mid 1800s, totalling 900 t (29 Moz) to 2005. In addition, there is potential for a further 1230 t (39.5 Moz) of gold in known and undiscovered deposits. Most of the gold has originated from epithermal and mesothermal (orogenic) hydrothermal systems. Epithermal gold occurs in the Northland, Coromandel and Taupo volcanic zones in quart...

The Rahmatabad Kaolin deposit is located about 25 km southwest of Nain. This deposit is formed by alteration process from Eocene volcanic rocks and pyroclastic units. Mineralogical studies display that the kaolinite, jarosite, hematite, quartz, calcite, anortite, alunite, diaspore, chlorite, montmorillonite, illite, albite, orthoclase, halite, sanidine, goethite, malachite, azurite and sericite...

The Almacık Block is a tectonic sliver formed during the activity of North Anatolian Fault Zone (NAFZ). It includes two important zones Western Pontides (NW Anatolia): İstanbul and Sakarya Zones meet along suture zone called Intra-Pontide Suture (IPSZ). units within are exposed in eastern part Block, whereas rocks west. In presented study, some magmatic have been analysed using zircon U-Pb meth...

The proposed project is set in pure mathematics within the areas of infinite-dimensional Lie theory and geometric group theory. Its goal is to contribute to the structure theory of unitary forms (i.e., centralisers of Chevalley involutions) of Kac–Moody algebras and of Kac–Moody groups of indefinite type. The main emphasis of this project will be on finite-dimensional representations and on ide...

Although cough medicine abuse is a growing problem in many places, there is no study examining the views of young substance abusers toward cough medicine. The objective of this study was to examine personal constructions of cough medicine abusers via the repertory grid tests (N = 11). Several observations are highlighted from the study. First, personal constructions of cough medicine were mixed...

Millions of courses of antibiotics are prescribed for children with acute cough illness each year, despite evidence from randomized, placebo-controlled trials that such treatment is not effective. Evidence that children with cough for <10 days should not be treated with antimicrobial agents is presented. Older children with prolonged cough or those with underlying lung disease may benefit from ...

For each standard affine data satisfying some condition on the coroots, we define a group functor on the category of all rings which is a subgroup of some group functor R 7→ G(R[t, t−1])o T (R), where G is a Chevalley scheme and T is a torus. This functor is then shown to satisfy the conditions of the five axioms required by [Ti4] to be a ‘minimal’ Kac-Moody group.

BACKGROUND Public-private partnerships are felt to be necessary for tuberculosis (TB) control in some developing countries. OBJECTIVES To evaluate the potential of a collaboration between the National TB Programme (NTP) and private pharmacies in Bolivia, the country with the highest TB incidence in Latin America. METHODS We contacted the local Pharmacists' Association in the city of Cochaba...
