the canola drying process was investigated using three laboratory scale dryers connected to a computer which continuously recorded the drying processes of each unit. a completely randomized design (crd) with three replications was used for the statistical analysis. the effect of temperature (40°, 50°, 60°c) and air velocity (1, 2 m/s) on the drying kinetics of a monolayer were studied. the effe...

background: stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. the four-point kneeling exercise is one of the most common types of stabilization exercises. this quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stage...

objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...

thermal rearrangement of 7,7-dichloro-[a,c]-dibenzo-[4,1,0]-bicycloheptane (1) to 5,6-dichloro-5hdibenzo-[a,c]-cycloheptene (2) was studied in the solid phase and in solvents with different polarities. thefirst-order constants at various temperatures for the rearrangement process were evaluated from theabsorption time data. the activation parameters for this rearrangement were obtained from the...

Thermo Gravimetric Analysis (TGA) analysis was employed to investigate activation energy (Ea) for the process of degrading of poly(o-toluidine) (POT) applying Horwitz & Metzger, Coats & Redfern and Chan et al., methods. POT was synthesized by chemical oxidative polymerization method using Ammonium per Sulphate (APS) as an oxidant while Dodecylbenzene Sulphonic Acid (DBSA) and sul...

The laboratory for instrumental neutron activation analysis at the Reactor Institute Delft, Delft University of Technology uses a network of 3 gamma-ray spectrometers with well-type detectors and 2 gamma-ray spectrometers with coaxial detectors, all equipped with modern sample changers, as well as 2 spectrometers with coaxial detectors at the two fast rabbit systems. A wide variety of samples i...

objective(s) doxorubicin (dox), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. curcumin, the active compound of the rhizome of curcuma longa l. has anti-inflammatory, antioxidant and anti-proliferative activities. curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with dox, but there is no study ab...

Instrumental neutron activation analysis (INAA) was applied for the accurate and precise determination of minor and trace elements in small-sized aliquants (1 to 2 mg) of two certified reference materials (CRM), NIES No. 8 and NIST 1632c. Four laboratories used either comparative- or k0-INAA, or both, and repeated the analysis more than ten times for each CRM. Based on z-scores and zeta scores ...

aim and background: asthma is a chronic illness that can severely affect people's lives. the aim of this study was to compare anxiety, depression, brain behavioural systems (bis-bas), coping styles, anger and hostility among people with and without asthma. methods and materials: fifty women with asthma attending shahid motahhari specialized clinic in shiraz and 50 normal women were selected usi...
