On accelerated iterative methods for the solution of systems of linear equations
(Taylor & Francis Ltd, 2002)
In literature, it has been reported that the convergence of some preconditioned stationary iterative methods using certain type upper triangular matrices as preconditioners are faster than the basic iterative methods. In ...
Nonsurgical treatment of a catamenial pneumothorax with a Gn-RH analogue
(Karger, 2002)
Catamenial pneumothorax is a rarely encountered entity characterized by recurrent pneumothorax concurrent with menstruation. Numerous mechanisms have been postulated in the etiology of catamenial pneumothorax and treatment ...
The precise human bioclock, possibly imported
(Churchill Livingstone, 2002)
Contrary to what has long been suggested, the biological clock is not a poor timekeeper. In fact, it has been working in precision for millions of years as a genetically set clock, independent of environmental periodicity. ...
Short-term effect of nasal intermittent positive-pressure ventilation in patients with restrictive thoracic disease
(Karger, 2002)
Background: The use of nasal intermittent positive pressure ventilation (NIPPV) would be expected to ameliorate dyspnea, ventilatory capacity and exercise tolerance durably in individuals with hypercapnic respiratory failure ...
Effect of trapidil in ischemia/reperfusion injury of peripheral nerves
(Oxford Univ Press Inc, 2002)
OBJECTIVE: Ischemia plays an important role in the development of pathological changes in nerve tissue, and restoration of blood flow results in injury (ischemia/ reperfusion [I/R] injury) mediated by toxic oxygen free ...
Tourniquet application and epinephrine injection to penile skin: is it safe?
(Springer-Verlag, 2002)
Although a tourniquet is frequently used in penile surgery there is still no consensus on safe application time. The aim of the present study is to investigate the effect of malondialdehyde (MDA) levels and histological ...
