A new preconcentration procedure to quantify total acid hydrolyzed fluoride in selected beverages and foods by spectrophotometry
(2015)
A new micellar-mediated, cloud-point extraction (CPE) method has been developed for the quantification of trace levels of fluoride by means of spectrophotometry. The method is based on the selective ion association of ...
Effects of al concentration on photovoltaic property of ZnO: Al/p-type si by pulsed filtered cathodic vacuum arc deposition system
(2015)
The effects of Al concentration on XPS, Raman, Hall and photovoltaic properties of Al-doped ZnO films were investigated onto Si (100) substrate by pulsed filtered cathodic vacuum arc deposition (PFCVAD) system, at room ...
Prevalence of sleep disorders in the Turkish adult population epidemiology of sleep study
(2015)
Sleep disorders constitute an important public health problem. Prevalence of sleep disorders in Turkish adult population was investigated in a nationwide representative sample of 5021 Turkish adults (2598 women and 2423 ...
Processing and mechanical properties of B<inf>4</inf>C/diamond impregnated Fe/Co MMC
(2015)
Cobalt is currently used in the production of diamond reinforced metal matrix composites (i.e. stone-cutting tools). Herein, how sintering temperature and matrix composition influences the material properties of diamond ...
In-hospital journey of patients with heart failure
(2015)
The number of patients diagnosed with heart failure (HF) is gradually increasing as a result of the increase in the elderly population. As the proportion of patients admitted to the emergency room with the diagnosis of ...
Lymphocytopenia is associated with poor NYHA functional class in chronic heart failure patients with reduced ejection fraction
(TURKISH SOC CARDIOLOGY, 2015)
Objective: In heart failure (HF) patients, functional capacity has been demonstrated to be a marker of poor prognosis, independent of left ventricular ejection fraction (EF). Lymphocyte count is currently recognized in ...
Investigation of thermal stress in different metal-ceramic restorations by mathematical analysis
(2015)
Objectives: The aim of this study was to investigate the effect of heat changes in oral environment producing thermal stresses (TS) in prosthetic restorations by a mathematical method. Material and Methods: Three different ...
