The Araçuaí and Ribeira orogens have been studied for decades, recently, these two were described as the Araçuaí–Ribeira Orogen System. Despite much work investigating this orogenic system, some issues, such connection between orogens, are still not fully understood. This aimed to present unpublished Lu-Hf data Santa Angélica Intrusive Complex (SAIC) host rocks that part of Rio Negro magmatic a...

hydraulic fracturing (hf), as a stimulation technique in petroleum engineering, has made possible the oil production from reservoirs with very low permeability. the combination of horizontal drilling and multiple hf with various perforation angles has been widely used to stimulate oil reservoirs for economical productions. despite the wide use of hf, there are still ambiguous aspects that requi...

background &objectives; : high fat (hf) diet by affecting the oxidative stress and nitric oxide (no) production may lead to different effects on function of the heart after myocardial infarction (mi). in the present study we aimed to address the hypothesis that high release of no by activated macrophages affects lv function after mi. methods : the animals were randomly divided into four groups ...

heart failure (hf) is still a major problem worldwide with high morbidity and mortality rates. the recently developed medication for hf is still incapable of reducing its morbidity and mortality, and clinical data supporting the efficacy and safety of its mainstay therapy remain insufficient. arginine-vasopressin (avp) plays important roles in circulatory and water homeostasis, one of which is ...

Introduction: Dental ceramics are considered as materials that can restore the appearance of natural teeth. Etching the inner surface of a ceramic restoration with hydrofluoric acid (HF) followed by using a silane coupling agent is a well-known and recommended method to increase the bond strength. The aim of etching on ceramic structure is to enhance the surface roughness (Ra) and energy and to...

Consider the link bandwidth allocation for transport of correlated traac on a single link with nite buuer capacity under a maximum allowable delay constraint d max. In our measurement architecture, traac is decomposed into three frequency regions: low-frequency (LF) traac in 0 < j!j ! L , high-frequency (HF) traac in j!j ! H and mid-frequency (MF) traac in ! L < j!j < ! H. The zero-frequency co...

OBJECTIVE Brain natriuretic peptide (BNP) has potent lipolytic action and, probably, a role in the biological mechanisms of obesity. Clinically, high levels are found in subjects with heart failure (HF). Low levels and inverse relation to BMI lead to questioning of its clinical utility in obese subjects, but heterogeneous results are found in severe obesity. METHODS In order to describe BNP b...

The Turán function ex(n, F ) of a graph F is the maximum number of edges in an F -free graph with n vertices. The classical results of Turán and Rademacher from 1941 led to the study of supersaturated graphs where the key question is to determine hF (n, q), the minimum number of copies of F that a graph with n vertices and ex(n, F ) + q edges can have. We determine hF (n, q) asymptotically when...

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...

Of the 16 presentations at the three Hotline sessions of the 30th European Congress of Cardiology, held in Munich, Germany, 30 August–3 September 2008, nine are summarized below, since the others have already been published (BEAUTIFUL, Lancet 2008; 372; 807–821; TRANSCEND, Lancet 2008: 372; 1174– 1183; GISSI-HF (n-3-PUFA), Lancet 2008 (Epub ahead of print); GISSI-HF (rosuvastatin), Lancet 2008 ...
