The use of roller compacted concrete (R.C.C) without conventional cover in important hydraulic structures is investigated through laboratory observation of abrasion phenomena sujected to high velocity flow and floating particles. The main parameters affecting abrasion and erosion resistance of R.C.C. studied in the present study include: "Mixed Hydraulic

Mean Radius" (which collectively ...
plants are always exposed to vast aspects of either environmental biotic or abiotic stresses and those stresses affecting the plant growth and therefore crop production. molecular and physiological mechanisms influence plant resistance to environmental stresses, therefore the identification of these mechanisms can be an important step in challenging the damages. in this study, plant physiologic...

twenty-two bread wheat cultivars along with susceptible (sholeh) and resistant (azadi) control cultivars were evaluated for resistance to russian wheat aphid of two growth stages including seedling and stem elongation in greenhouse. five adult aphids per plant were used for infestation. leaf chlorosis at seedling and stem elongation stages and leaf rolling at seedling stage were measured. other...
Ilvaite is a mixed-valence Fe-bearing sorosilicate, typically occurring as a late forming mineral in Ca-Fe-Si skarn deposits (Burt 1971). Its chemical composition does not differ significantly from the ideal end-member, Ca Fe2Fe (Si2O7)O(OH), except for a considerable amount of Mn, mainly substituting for Fe and, to a lesser extent, Ca (Carrozzini 1994); minor replacement of Fe and Fe by Mg and...
Incontrovertibly each person’s body has an undeniable role in shaping personality and in self- definition of ego. Nowadays and based on scientific efforts, we know sex and accordingly, gender, as a spectrum in inter bodily experience. Over the long years intersex status was considered a "disorder", but recently and in the light of modern medical, psychiatric and cognitive science, "different" e...
Acknowledgement Although developing Aryan was my dissertation project, I had the advantage of having many people by my side without whom this wouldn't have been possible. Hereby, I would like to acknowledge each of their contributions in the process. Professor Cynthia Breazeal is the first person I owe my deepest appreciation to. She had a major role to get this project up and running. When I f...

Background and Objectives: The subtilisin genes (SUBs) of Trichophyton rubrum play an important role in destroying the keratin to produce a nutritional source and virulence. This study was carried out to determine the presence of subtilisin genes in T. rubrum isolated from patients with dermatophytosis in Tehran in 2017. Materials and Methods: This descriptive study was performed on 32 pati...
An unusually Mn-rich ilvaite sample from the Perda Niedda mine in Sardinia, Italy, was studied in order to clarify the Mn distribution among the different structural sites, and to observe the structural response of the mineral upon thermally induced oxidation-dehydrogenation. The crystal structure and the chemical composition of one crystal [a = 13.014(5), b = 8.867(3), c = 5.838(4) Å, b = 90.0...
