In this paper, a certain type of ammunition bracket was studied, the stress distribution under working load is calculated by static analysis and display Graphic Tee dynamic analysis, the stress distribution result show that the maximum load during the working cycle is the instantaneous impact force.Through ANSYS software, Goodman theory method was
An important metric for many aspects of species conservation planning and risk assessment is an estimate of total population size.For landbirds breeding in North America, Partners in Flight (PIF) generates global, continental, and regional population size estimates.These estimates are an important component of the PIF species assessment process, bu
Abstract Background Metazoan cells only utilize a small subset of the potential DNA replication origins to duplicate the whole genome in each cell cycle.Origin choice is linked to cell growth, differentiation, and replication stress.Although various genetic and epigenetic signatures have been linked to the replication efficiency of origins, there i
The seismic rehabilitation of existing r.c.and masonry buildings is a topical issue in Civil Engineering.A useful technique consists in the introduction of external bracing system.This kind of intervention can be improved throughout the introduction of dissipative links, here investigated with the help of some examples.The Braces links are made of
BACKGROUND:Phlebotomus (Paraphlebotomus) sergenti is at least one of the confirmed vectors for the transmission of cutaneous leishmaniasis caused by Leishmania tropica and distributed widely in Morocco.This form of leishmaniasis is considered largely as anthroponotic, although dogs were found infected with Leishmania tropica, suggestive of zoonosis
