In this study, the effect of earthquake loads on roof gable walls and the behaviours of these roof gable walls are investigated.In preparation of the study, two experiments on cradle roof system which gets and does not get any loads off the roof members were carried out in all.The experiments were performed on the shaking table in Earthquake Resear
Uncoupling between molecular and morphological evolution is common in many animal and plant lineages.This is especially frequent among groups living in ancient deep lakes, because these ecosystems promote rapid morphological diversification, and has already been demonstrated for Tanganyika cychlid fishes and Baikal amphipods.Ostracods are also very
Habitat assessment of species is one of the most important strategies to conserve biodiversity in the protected areas.The main objective of this study is to present an ecological assessment model for habitat management of brown bears using the MaxEnt algorithm in Oshtorankooh protected area, Lorestan.55 presence points of brown bear and seven envir
We investigated structure optimization, mechanical stability, electronic and bonding properties of the nanolaminate compounds Ti2PbC, Zr2PbC, and Hf2PbC using the first-principles calculations.These structures display nanolaminated edifices where MC layers are interleaved with Pb.The calculation of formation energies, elastic moduli and phonons rev
