abstract this study examined the relationship between noticing pronunciation and the improvement pronunciation by administering a 50 item story, as proficiency- test in order to investigate the effectiveness of noticing pronunciation on the improvement of pronunciation. accordingly 60 qualified students were selected and assigned to the two groups of experimental and control randomly, each gr...
Ultrasonic Patches In article number 2100785 by Xue Feng and co-workers, a flexible ultrasonic patch is designed fabricated for chronic wound treatment. While the applied to damaged area of wound, it makes conversion Rac1-GDP Rac1-GTP, which can accelerate healing wound. The soft, light completely conform treatment treat effectively.
AIM To evaluate the clinical treatment effects of a glycine powder air-polishing or ultrasonic device on peri-implant mucositis. MATERIALS AND METHODS Thirty-seven patients with one implant diagnosed with peri-implant mucositis (probing depth ≥4 mm (0.2N) and bleeding on probing (BOP) (primary outcome)) were randomly assigned to treatment with either glycine powder air-polishing (GPAP) or ult...
Xylanase treatment can be an environmentally friendly way to improve the formability and drainability of chemi-mechanical pulp (CMP). Improvements in xylanase treatment efficiency are possible with application of an ultrasonic wave via the cavitation effect. Results showed that the specific surface area (SSA) of the combined treated pulp increased by 14.6% at an ultrasonic treatment of 30 min a...
abstract the following study, in the first place, attempted to examine the effect of less experienced teachers participation in experienced teachers classes on their own skills and teaching methodology, in the second place, attempted to find out the role of teachers training in students achievements. for this purpose, 21 efl teachers were selected according to available sampling in kish l...
A full matrix capture technique is presented that allows for real-time imaging through a non-planar surface where the geometry is known. For an identified geometry the point of incidence at the refractive interface is calculated using Fermat’s principle and iterative techniques for each possible transducer position which is pre-processed ahead of the inspection. This information is combined wit...
This paper presents two novel applications of ICA in Non Destructive Evaluation by ultrasounds applied to diagnosis of the material consolidation status and to determination of the thickness material profiles in restoration of historical buildings. In those applications the injected ultrasonic pulse is buried in backscattering grain noise plus sinusoidal phenomena; this latter is analyzed by IC...
This article addresses the effect of ultrasonication as a pretreatment to anaerobic digestion of four types of animal manure, including swine slurry, beef feedlot manure, dairy manure slurry, and separated dairy manure effluent. The effect of ultrasonication on soluble chemical oxygen demand (SCOD) and biochemical methane potential (BMP) were determined, and the energy efficiency of ultrasonic ...
Medical plants are adapted to different kinds of dormancy to survive in the worst situations. Regarding to ecological viewpoint, this kind of adaptation is very important in respect to restriction of genetic draft and decrease of genetic resource of medicinal plants. This leads to plant survival even after prolonged drought. Since some of them are endangered species and in the other hand increa...
