Background: Virtual education refers to a variety of teaching-learning methods that are implemented and supported electronically. The present study was conducted to determine the effects of group blogging on the attitude of nursing students towards virtual education.    Methods: This was a quasi-experimental pretest-posttest study in which all fifth-semester nursing students (n=25) w...

Due to the frequent drought periods, water consumption increase, and competition of different water-using sectors, the Hirmand catchment is in a critical water status in the Sistan region. This threat has been intensified in recent years. To cope with this problem, we must pay more attention to different types of water use such as virtual water as a water saving method. The present study calcul...

in  this paper  thin  films of  tin sulfide (sns) were deposited on  the glass substrates using spray pyrolysis method with the substrate temperatures in the range of 400–600℃, keeping the other deposition parameters constant. in  this work  the characteristic of sns  thin  films  investigated. the xrd pattern and optical transmittance of thin films also are discussed. with the change in concen...

substrates' concentration profile was studied in a porous matrix containing immobilized amyloglucosidase for glucose production. this analysis was performed by using an analytical method called least square method, and the results were compared with numerical solution. effects of effective diffusivity, michael's constant, maximum reaction rate and initial substrate concentration were studied on...
