Zein-based nano/microparticles have been demonstrated to be promising carrier systems for both the food industry and biomedical applications. However, the fabrication of size-controlled zein particles has been a challenging issue. In this study, a modified anti-solvent precipitation method was developed, and the effects of various factors, such as mixing method, solvent/anti-solvent ratio, temp...
از آنجا که یادگیری لغت یکی از پایه های اساسی فراگیری زبان خارجی است و در سیستم آموزش و پرورش وقت بسیار کمی به آموزش زبان انگلیسی اختصاص داده شده است محقق برآنست به بررسی سه فعالیت که گمان می رود به بسط دانش واژگانی فراگیران کمک می کنند بپردازد.
BACKGROUND The purpose of this study was to determine the impact of instructor feedback and video tutorials on skill acquisition during proficiency-based laparoscopic suturing training. METHODS Performance data from a prospectively maintained database were reviewed for three groups of novices (n = 34 medical students) who completed the same proficiency-based laparoscopic suturing curriculum o...
The "flipped classroom" is a learning model in which content attainment is shifted forward to outside of class, then followed by instructor-facilitated concept application activities in class. Current studies on the flipped model are limited. Our goal was to provide quantitative and controlled data about the effectiveness of this model. Using a quasi-experimental design, we compared an active n...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
sex-linked mutant scute (sc), its noma1 allele, and a number of minor Tf:nes which can be shown to exist by selective breeding, form a developmental system which determines the number of bristles on the scutellum of Drosophila mlanogaster. In unselected stocks almost all flies grow four bristles when one or two + genes are present at the scute locus; that is, development is canalised at this le...
Introduction Supercontinuum (SC) has attracted considerable attentions due to its versatility in many fields such as telecommunication [1], optical metrology [2] and medical science. The SC phenomenon originates from the third-order nonlinearity of the media. In nonlinear optical fibers, both chromatic dispersion and nonlinear effects determine the SC generation characteristics. Different dispe...
