abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
background: dielectric barrier discharge (dbd), a source of non-thermal plasma, is used in surface decontamination. objective: to study the effect of dbd plasma treatment, we evaluated the effect of plasma exposure time on inactivation of bacillus subtilis. results: applying the dbd plasma to the culture of b. subtilis caused complete sterilization of the surface without any thermal effects. in...
in this study the effect of the alkylating agent, sulfur mustard, on calf thymus chromatin was investigated using uv/vis spectroscopy, gel electrophoresis and thermal denaturation techniques. the results show that treatment of isolated chromatin with sulfur mustard releases histones from the core particles but does not affect histone h i and nonhistone chromosomal proteins. the content of relea...
Neopentyl glycol (NPG) has been extensively used as solid-solid phase change materials (PCMs) for thermal energy storage applications. The objective of the present study was to evaluate the impact of biofield treatment on physical, spectral and thermal properties of NPG. The study was performed in two groups (control and treated). The control group remained as untreated, and treatment group was...
OBJECTIVE To compare the benefits of a thermal cure and non-thermal rehabilitation in treatment of knee osteoarthritis (KOA). METHODS Randomized therapeutic trial including patients with knee osteoarthritis (American College of Rheumatology criteria). Patients were randomly divided into two groups. Spa treatment consisted of underwater shower, massage-jet showers, hydromassage, pool rehabilit...
Six Holstein cows (averaging 475 kg body weight, 2.3 parities and 96 d in lactation) fitted with catheters in the hepatic portal vein, mesenteric vein and intercostalis posterior artery were exposed to treatments of thermal comfort environments with libitum or restricted (75% of ad libitum) DM intake and a thermal stress environment with ad libitum intake in two balanced 3 x 3 latin squares to ...
ABSTRACT No comparison exists between laser and other non laser modalities. we have reviewed our 6 years experience in 34 consecutive patients with the endoscopic diagnosis of WMS. All patients were followed up.Coexistent disorders included systemic sclerosis,choronic renal failure ,cirrhosis, rheumatoid arthritis, diabetes mellitus,malignancy . Endoscopic ablation of WMS had been indertaken i...
The study addresses the effect of thermal treatment on the internal structure of polyelectrolyte multilayers (PEMs). In order to get insight into the internal structure of PEMs, Neutron Reflectometry (NR) was used. PEMs with a deuterated inner block towards the substrate and a non-deuterated outer block were prepared and measured in 1% RH and in D2O before and after a thermal treatment. Complem...
Today the use of pretreatment operations to reduce time, energy and cost of drying of agricultural products and foodstuffs are taken into consideration. In this study the Rosemary herb dried by using the microwave pre-treatment at three treatments (90 W for 5 min, 180 W for 2.5 min and 360 W for 1.5 min) and control treatment (without pre-treatment) in a hot air dryer at temperatures of 40, 50 ...
