A safe and effective method for treatment of chronic subdural haematoma
(CANADIAN J NEUROL SCI INC, 2007)
Objective: Burr-hole irrigation and burr-hole drainage without irrigation are the most popular methods for treatment of chronic subdural haematoma. It is not well known if irrigation is necessary or which method has a ...
Modeling and optimization of Multi-Gravity Separator to produce celestite concentrate
(ELSEVIER SCIENCE SA, 2007)
In this study, a three-level Box-Behnken factorial design combined with response surface methodology (RSM) for modeling and optimizing of some operations parameter of Multi-Gravity Separator (MGS) to produce a celestite ...
A parametric study of phenolic compounds desorption performance from organobentonite by supercritical fluids
(ELSEVIER SCIENCE BV, 2007)
Supercritical fluid desorption has been carried out in a fixed bed column to desorp nitrophenolic compounds from organically modified bentonite. The experiments were carried out in the sequence of synthesis of organobentonite ...
Screening of the antioxidative properties and total phenolic contents of three endemic Tanacetum subspecies from Turkish flora
(ELSEVIER SCI LTD, 2007)
Methanolic extracts of three different Tanacetum subspecies [Tanacetum densum (Lab.) Schultz Bip. subsp. sivasicum Hub-Mor and Grierson, Tanacetum densum (Lab.) Schultz Bip. subsp. eginense Heywood and Tanacetum densum ...
Alterations in spontaneous contractions of rat proximal and distal colon after peritonitis
(W B SAUNDERS CO-ELSEVIER INC, 2007)
Background/ Purpose: The aim of this study was to investigate the effect of peritonitis on spontaneous contractions of distal and proximal colon smooth muscle isolated from rats. Methods: Peritonitis was induced by cecal ...
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. ...
