This paper contains a strain gradient theory to capture size effects in rotating nanodisks of variable thickness under thermal and mechanical loading. Material properties of nanodisks have been taken homogeneous material. The strain gradient theory and the Hamilton’s principle are employed to derive the governing equations. Due to complexity of the governing differential equation and boundary c...

Are 15-month-old infants able to detect a violation in the consistency of an event sequence that involves pretense? In Experiment 1, infants detected a violation when an actor pretended to pour liquid into one cup and then pretended to drink from another cup. In Experiment 2, infants no longer detected a violation when the cups were replaced with objects not typically used in the context of dri...

Current research examines the economic, social, cultural, policy, educational and promotional factors in using sustainable agriculture operations. Research is an applied type and its method is correlation. The statistical population consisted of 102 members of Iran Potato Cultivars. Data were collected using a census method and a questionnaire was used. The Cronbach's alpha coefficient was obta...

The cell adhesion molecule L1 (L1-CAM) plays critical roles in neurite growth. Its cytoplasmic domain (L1CD) binds to ankyrins that associate with the spectrin-actin network. This paper demonstrates that L1-CAM interactions with ankyrinB (but not with ankyrinG) are involved in the initial formation of neurites. In the membranous protrusions surrounding the soma before neuritogenesis, filamentou...

In this paper, we study relation and impact of social capital on organizational commitment among staffs of Islamic Azad University, Branch of Ayatollah Amoli. The data required were collected by using field (survey) research method and the questionary tool. Statistical population was included 152 subjects that 108 subjects were selected based on Morgan table. The descriptive results show that c...

The facility interest rate is one of the most important macroeconomic variables. The bank facility interest rate is associated with other macro-economic variables, one of which is the bank deposit interest rate. Using the time series data of the 1973-2017 period and the simultaneous equation system, the researchers estimated four equations using the three-stage least squares method.The result o...
