Ductile failure prediction of U-notched bainitic functionally graded steel specimens using the equivalent material concept combined with the averaged strain energy density criterion

The final publication is available at Springer via http://dx.doi.org/10.1134/S102995991903010XIn this paper, the ductile fracture of bainitic functionally graded steel has been studied. Fracture tests was performed on U-notched specimens made of bainitic functionally graded steel under mode I. The averaged strain energy density criterion combined with equivalent material concept was employed to predict the ductile fracture of bainitic functionally graded steel. For this purpose, first, based on equivalent material concept, the mechanical properties of virtual brittle functionally graded steel were obtained. Then the averaged value of strain energy density over a well-defined control volume was calculated by finite element analysis for U-notched virtual brittle functionally graded steel. After that, the fracture loads was obtained based on the averaged strain energy density criterion. The agreement between experimental fracture loads and theoretical predictions was good.Peer ReviewedPostprint (author's final draft

Bicultural Iranians’ political tendency: in between two cultures

The present study aimed to examine differences in a range of psychosocial variables and  political tendencies across three groups, namely Iranian new-comers (who have lived in the UK for less than two years), bicultural Iranians (born and raised in the UK or raised in the UK since they were under 10 years old), and UK citizens (bicultural participants were excluded). The target variables measured in the present study consisted of empathy, Theory of Mind (ToM), flexibility, suggestibility, openness to experiences, normative identity style, interpersonal trust, prosocial behaviour, egalitarian sex role, authoritarianism and adherence to democracy. A series of MANOVAs revealed significant main group effects for most of variables. The results of post hoc and polynomial tests yield an incremental linear trend on empathy, theory of mind, interpersonal trust, openness, prosocial behaviour and adherence to democratic values for groups ordered as Iranian new comers, bicultural and British; a decreasing trend was also observed on normative identity style, suggestibility, and authoritarianism. The between-two cultures’ findings of bicultural group might be explained by learning through political socialization. This provides support for the fact that being raised in a different cultural setting can have a vivid impact on people’s psychological characteristics and socio-political tendency

Determination of nutritional requirements of kutum fish (Rutilus frissi kutum) fingerling

Three experiments carried out to determine optimize level of crude protein, lipid and gross energy requirements of Kutum fish (Rutilus frissi kutum) fingerling. A completly randomized design consisted of 4 treatments with triplicates which those was used with four experimental dietary crude protein levels (35, 40. 45 and 50% CP), Four crude lipid levels (8, 12, 16 and 20%) and four gross energy levels (4250, 4500, 4750 and 5000 k cal/kg of diet) being tested separately. Kutum fish fingerling averaging 1067 ± 98 mg,,2378 ± 185 mg, and 1067 ± 143 mg respectively and stocked with density of 20 fish at volum 80 liters. Fish fed with 3% of wet body weight at three times, 9 am, 12 am and 4 pm. The following performance parameters were evaluated final weight, weight gain, feed intake, feed conversion ratio, specific growth rate, protein effieciency ratio and condition factor. Fish fed diets 40% CP, 20% CL and 4500 K Cal/kg Gross energy could meet the nutritional requierments of kutum fish fingerling
