A macroscopic model of Columnar-to-Equiaxed Transition (CET) formation is presented. The growth of a columnar zone and an equiaxed zone are treated separately and modeled on a fixed grid. The model uses a columnar Front Tracking (FT) formulation to compute the motion of the columnar front and the solidification of the dendritic columnar mushy zone. The model for the equiaxed zone calculates the...

BACKGROUND We assessed the efficacy of amifostine for protection from chemotherapy-induced toxicities in patients treated with conventional-dose paclitaxel, ifosfamide, cisplatin (TIP) and high-dose carboplatin, etoposide and thiotepa (CET) followed by peripheral blood progenitor cell (PBPC) rescue. PATIENTS AND METHODS In a prospective single-center study 40 patients with relapsed or refract...

OBJECTIVE This randomized clinical trial was designed to compare the effects of a theory-based coping effectiveness training (CET) intervention with an active informational control (HIV-Info) condition and a waiting-list control (WLC) condition on psychological distress and positive mood in HIV-seropositive gay men. MATERIALS AND METHODS The authors recruited 149 self-identified gay or bisexu...

BACKGROUND The relative efficacy of conventional exercise therapy (CET) and behavioural graded activity (BGA) has not been fully established to inform the preference in clinical practice. OBJECTIVE To compare CET and BGA on the treatment outcome of chronic non-specific low back pain (LBP). METHODOLOGY Participants were assigned into either BGA or CET group in this randomized feasibility int...

a chemiluminescence (cl) method has been developed for the determination of hydroxyzine (hyd) and its metabolite cetirizine (cet). the method is based on sensitizing effect of cet and hyd on the weak cl reaction between ru(phen)32+ and acidic ce(iv). a mechanism for the cl reaction has been proposed on the basis of uv-vis, fluorescent and cl spectra. by using the recommended procedure, the cali...

BACKGROUND Comprehensive exercise training (CET) is an efficient strategy to decrease dyspnea perception in chronic obstructive pulmonary disease (COPD) and may result in significant improvement in ventilatory muscles function. Our aim was to evaluate the effects of general exercise training on dyspnea perception and on respiratory muscles strength in COPD patients. METHODS Consecutive COPD p...

au cours de cet article nous allons définir le concept de l’espace culturel dans la condition humaine d’andré malraux. l’«interculturel» représente une notion dynamique qui renferme l’idée de mouvement, de contact, d’interaction et d’interéchange entre deux ou plusieurs cultures. les individus appartenant aux  diverses cultures insinués dans un même contexte socio-culturel, communiquent les uns...

a simple, accurate and rapid high performance thin layer chromatography (hptlc)-densitometric method was developed for separation and determination of cetirizine (cet) as a long acting antihistamine and montelukast (mon) as an antileukotriene in pharmaceutical dosage forms. the compounds were separated on silica gel 60 f254 hptlc plates using a mixture of ethyl acetate : methanol : ammonia solu...

BACKGROUND AND OBJECTIVE Cycle ergometer training is an important component of pulmonary rehabilitation for patients with COPD. However, incremental cycle tests from which individualized cycle training intensity can be prescribed may not be readily available to clinicians. The aims of the study were to (i) investigate the physiological and psychophysical responses to the 6-min walk test (6MWT),...
