background: genetic polymorphism of milk proteins has been associated with composition, manufacture, and traits of milk. caseins are the most important milk proteins whose genes are strongly linked and inherited as a raceme. κ-casein which is a quantitatively minor constituent of bovine milk is thought to play a critical role in organization, fixation and aggregation of casein micelles and firm...

conclusions in this study, phylogenetic reconstruction of hcv-1 sequences clearly indicated for molecular tracing and ancestral relationships of the hcv genotypes in iran, and showed the likelihood of domestic origin for hcv-1a and various origin for hcv-1b. evidence acquisition the phylogenetic analyses were performed based on the nucleotide sequences of ns5b gene of hcv genotype 1 (hcv-1), wh...

background: mycoplasmas can cause acute and chronic diseases at multiple sites with wide-range complications and have been implicated as cofactors in diseases. the infections influenced form genital mycoplasmas specifically mycoplasma hominis and mycoplasma genitalium potentially affect reproductive disorders, and infertility. objective: isolation and molecular identification of mycoplasma geni...

Bridge structure performance estimation under a seismic hazard can be significantly influenced by the level of modelling detail within the simulation of the soil structure interaction phenomenon. As the computational demands of such estimation greatly restricts the implementation of a detailed truncated FEM simulation of the semiinfinite soil domain, the Kelvin – Voigt Model within the framewor...

Correlation of the coda of large earthquakes can be used to retrieve body waves at teleseismic distances. This retrieval depends on waves propagating with equal energy in all directions (equipartitioning). We carry out a beamforming analysis of body waves at periods of 10 and 40 s recorded at USArray and show that the late coda, up to 10 h after the Okhotsk earthquake, is dominated by waves pro...

tivity phenomenon that is widely accepted as indicating the base of the gas-hydrate stability zone. The acoustic impedance difference between sediments invaded with gas hydrate above the BSR and sediments without gas hydrate, but commonly with free gas below, are accepted as the conditions that create this reflection. The relationship between BSRs and marine gas hydrate has become so well known...

Traditionally the foundation in a dam is modeled by a sub-structuring approach for the purpose of seismic performance analysis. The main disadvantage of sub-structuring approach is that it cannot be used for solving nonlinear dynamic problems. Therefore, in that case seismic response analysis must be carried out in time domain. Among the different earthquake input mechanisms the deconvolved ear...

The present study evaluates how the soft first story irregularity condition should be defined: (a) as a significant reduction of the lateral shear stiffness of all resisting frames within a given story, as established in the seismic provisions of Mexican building codes or, (b) as a substantial reduction of the lateral shear stiffness of one or more resisting frames within a given story, as prop...
