BACKGROUND Addressing vulnerability to heat-related mortality is a necessary step in the development of policies dictated by heat action plans. We aimed to provide a systematic assessment of the epidemiologic evidence regarding vulnerability to heat-related mortality. METHODS Studies assessing the association between high ambient temperature or heat waves and mortality among different subgrou...
A spherical parallel manipulator (also called an orientational parallel manipulator or rotational parallel manipulator) refers to a threedegree-of-freedom (3-DoF) parallel manipulator in which the moving platform undergoes a 3-DoF spherical motion or rotates about a fixed point. In this paper, we propose a new method for the type synthesis of non-overconstrained (isostatic) spherical parallel m...
Bu çalışmada, ışgının çiçek (RRF), yaprak (RRL) ve kök (RRR) gibi farklı bölgelerinin ayrı özütleri hazırlanarak asidik ortamda bakırın korozyonuna koruma etkileri incelenmiştir. Böylelikle kullanılmayan diğer kısımlarının da faydaya dönüştürülmesi mümkün olabilecektir. amaçla, RR özütlerinin 1 M HCl çözeltisinde 1000 ppm çözeltileri hazırlanmıştır. Bakır metalinin bu çözeltilerdeki elektrokimy...
In the abstracts in this journal that describe effective treatments, we provide our readers with numbers that summarise their clinical effect. These include the number of patients you need to treat to prevent I adverse outcome (NNT) and both die absolute risk reduction (ARR) and relative risk reduction (RRR) in the occurrence of adverse outcomes achieved by active therapy. In this EBM Note, we ...
BACKGROUND Randomized trials have established statins as an agent for prevention of coronary heart disease (CHD). The purpose of this study was to assess the hypothesis that standard-dose statin therapy has a beneficial effect in normocholesterolemic diabetic patients with CHD. METHODS AND RESULTS A prospective, randomized, open, blinded-endpoint trial was conducted from 2002 to 2004 at 55 ho...
We identified urinary polyphenol metabolite patterns by a novel algorithm that combines dimension reduction and variable selection methods to explain polyphenol-rich food intake, and compared their respective performance with that of single biomarkers in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. The study included 475 adults from four European countries (Ger...
AIM To detect and quantify dentine sialoprotein (DSP) in the gingival crevicular fluid (GCF) of luxated teeth. METHODOLOGY Eighteen subjects were enroled and distributed as follows. Group I (n = 6, positive control): subjects with primary second molar teeth undergoing physiological root resorption. Group II (n = 6, negative control): subjects with permanent mature maxillary central incisors. ...
Spatial Data Infrastructures (SDI) aim to link people with spatial services and data. Increasingly, SDI initiatives are focusing on a particular type of data: large-scale people relevant data. Examples include the ownership parcel layer and built environment information. To improve the management of these essential SDI layers, consideration of land parcels and their administration is needed. In...
In layout problem of manufacturing cells, cells have rectangular shapes and must be positioned without overlapping. The objective is to minimize the total transportation cost. RRR 1-2014, May 2014 Page 1
AIMS To describe the drinking patterns and their baseline predictive factors during a 12-month period after an initial evaluation for alcohol treatment. METHODS CONTROL is a single-center, prospective, observational study evaluating consecutive alcohol-dependent patients. Using a curve clustering methodology based on a polynomial regression mixture model, we identified three clusters of patie...
