hydrogels are introduced to modem medicine as novel materials suitable for a variety ofbiomedical applications. studying hydrogels as novel biomaterials has become a fast-developingand exciting research field during the last two decades. these interesting biomaterials have found awide range of application including contact lenses, vehicles for drug delivery and scaffold in tissueengineering and...

in this paper, i attempt to bring together approaches to literacy in theory and in practice, drawing upon various activities i have been involved in over the years–research in iranian villages during the 1970s; linking research and theory to literacy policy, with particular reference to a contribution to the unesco global monitoring report in 2004 and involvement in an ongoing adult literacy tr...

  In the present study, the effect of stirring speed and the type of cross linking agent on the size and formation of microencapsulated Silver carp (Hypophthalmichthys molitrix) oil were investigated. The gelatin/gum Arabic was used for encapsulating and the capsules were prepared by complex coacervation. Microcapsules were analyzed by optical microscopy technique and particle size analyzer. Re...

Iranian identity cannot be conceived of as a uniform monolithic concept. But, thanks to certain upheavals in the history of the country, it has turned into the triple concept of national/Islamic/modern. Hofstede’s (2001) cultural framework represents a well-validated operationalization of culture based on six cultural dimensions  (power distance, individualism/collectivism, masculinity/feminini...

Polyethylene’s application for insulating is highly advanced but due to thermoplastic properties, its application confronts constraints such as the limited 70°C temperature of the conductor. Polyethylene thermosetting procedure in which molecules are knotted and a 3D-molecular-network formed is developed to conquer the mentioned problem and to raise the applicable temperature of the i...
