The present paper aims to determine the relationship between ICT usage and generation gap in Tehran urban family. This research is based on a survey in which a systematic random sampling of 384 families has been chosen to be questioned from different districts of Tehran. The results of the test showed a meaningful relationship between the usage of ICT and generation gap in urban households of T...

In this study, thermodynamic and economic analysis of a photovoltaic electricity generation system (PVEGS) with and without self-cleaning panels is reported. In the first part, thermodynamic analyses are used to characterize the performance of the system. In the second part, the economic comparison of photovoltaic electricity generation with and without self-cleaning panels is carried out for a...

Search-based optimization methods have been used for software engineering activities such as software testing. In the field of software testing, search-based test data generation refers to application of meta-heuristic optimization methods to generate test data that cover the code space of a program. Automatic test data generation that can cover all the paths of software is known as a major cha...

   Transmission era from tradition to modernity has been accompanied by cultural, economic, social and political changes. Rapid Social and Cultural changes of recent decades in developing countries, including Iran, have affected the Social and Cultural Values of Parents and children and have caused what is named as “Generation Gap”. The purpose of this paper is to designate the relationship bet...

The present study carefully examined entropy generation during wustite pellet reduction to sponge iron. The finite volume method was used to solve the governing equations. The grain model was used to simulate the reaction rate. The reactant gases including carbon monoxide and hydrogen were converted to water and carbon dioxide after wustite reduction. Entropy is generated by heat transfer, mass...

background; water treatment sometimes needs a coagulation and flocculation process to remove suspended and colloidal materials. inorganic coagulants used create concerns about pollution of the environment and harmful effects on the human’s health. the studies carried out previously indicated the capability of an active coagulant agent extracted from descurainia sophia seed to remove turbidity o...

Traditional Iranian Medicine (TIM) consists of the sum total of all the knowledge and practices used in Persia from ancient times to now, from generation to generation relying exclusively on practical experience and observation handed down from generation to generation. TIM roots go back to over 2000 years ago and It is not too bold to go even further and claim that the Persians taught the Gree...

The present study investigates the hydrophilic properties of acrylonitrile/acrylic acid P(AN/AA) copolymer films with various acrylic acid (AA) contents dendrigrafted with citric acid from zero to fourth generation numbers. It was found that the hydrophilicity of the dendrigrafted films was a complicated phenomenon. Various parameters such as intermolecular hydrogen bonding, roughness and activ...
