abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
BACKGROUND To highlight the usefulness of reverse radial artery flap in covering various soft tissue defects of hand in paediatric age group. METHODS A total of 16 reverse radial artery flaps were utilized in a period of three years to cover various soft tissue defects of hand for paediatric age group patients. The age ranged from 5-18 years. The two common causes of soft tissue defects in th...
BACKGROUND Long-term outcomes of major upper extremity replantations are infrequently reported. It is believed that replantation is indicated for amputations at all levels in children and for all distal amputations in adults. Replantations of arm or proximal forearm amputations in adults are controversial. OBJECTIVE To evaluate the results of major upper extremity replantations, defined as th...
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
OBJECTIVES The aim of this study was to evaluate long-term clinical and functional results of major upper extremity replantations. METHODS We retrospectively evaluated 26 male patients (mean age 27 years; range 3 to 69 years) who underwent major upper extremity replantations and had a mean follow-up of 11.3 years (range 5 to 19 years). The levels of the replantations were transmetacarpal (n=6...
اکسیدهای آهن ترکیبی شیمیایی از آهن و اکسیژن می باشند. بطور کلی 16 نوع ترکیب شناخته شده از اکسیدها و هیدروکسیدهای آن وجود دارد. در میان این اکسیدها، آهن 3 اکسید(fe2o3) بسیار مورد توجه است. این اکسید خود از چهار فاز متفاوت آلفا، بتا، گاما و اپسیلون با ویژگیهای منحصر به فرد تشکیل شده است. فاز گامای این اکسید (?- fe2o3)، مگهمایت نام دارد که ساختاری کریستالی و ایزومتریک داشته و فری مغناطیس است. این ...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (goetz technique). primary healing occurred in all of them without any complication. the conception rate obtained after surgery was 70.1%. five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. three mares have produced several healthy foals without any ...
BACKGROUND The ischemic "steal" syndrome complicates angio-access in a growing number of hemodialysed patients. Until now, operative attempts (fistula ligation or banding) to treat this problem have met with only limited success. OBJECTIVE To assess the results of DRIL (distal revascularization-interval ligation) procedure in treating the "steal" syndrome. METHODS A retrospective review (19...
