Application of Box-Behnken design and response surface methodology for modeling of some Turkish coals
(ELSEVIER SCI LTD, 2007)
The aim of our research was to apply Box-Behnken experimental design and response surface methodology for modeling of some Turkish coals. As a base for this study, standard Bond grindability tests were initially done and ...
Density of impurity states of hydrogenic impurities in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We investigated the effects of the magnetic field on the density of impurity states in a GaAs/GaAlAs inverse parabolic quantum well (lPQW) for different Al concentrations at the well center. The calculations were performed ...
Comparison of myocardial performance index versus ratio of isovolumic contraction time/ejection time in left ventricular systolic dysfunction
(SPRINGER, 2007)
Myocardial performance index (MPI) has been regarded as an important parameter in the evaluation of ventricular systolic function in congestive heart failure. This study was designed to investigate the relationship between ...
Comparison of nasal volume changes during rapid maxillary expansion using acoustic rhinometry and computed tomography
(OXFORD UNIV PRESS, 2007)
The purpose of this study was to compare nasal volume changes using acoustic rhinometry (AR) and computed tomography (CT). The subjects were 10 children (6 girls and 4 boys, with an age range of 12-14 years) who required ...
Evaluation of pressure ulcer risks in patients with the cerebrovascular disease
(UNIVERSITATSVERLAG ULM GMBH, 2007)
It is known that patients with neurologic disorders are at high risk for the development of pressure ulcers. The most effective approach in pressure ulcers is the identification of patients at risk and their prevention. ...
