Crystal nucleation and growth processes induced by an externally applied shear strain in a model metallic glass are studied by means of nonequilibrium molecular dynamics simulations, in a range of temperatures. We observe that the nucleation-growth process takes place after a transient, induction regime. The critical cluster size and the lag-time associated with this induction period are determ...
We have carried out a survey for CO J=1-0 and J=2-1 emission in the 260 early-type galaxies of the volume-limited ATLAS sample, with the goal of connecting their star formation and assembly histories to their cold gas content. This is the largest volume-limited CO survey of its kind and is the first to include many Virgo Cluster members. Sample members are dynamically hot galaxies with a median...
pasteurella multocida is considered to be an important cause of ovine pneumonia and results causes considerable economic losses in iran. ribotyping pcr (ribo-pcr) was used for investigating the diversity of ovine and caprine p.multocida. a total of 120 swab tonsil and nasal samples were obtained from sheep and goats. they were analyzed by biochemical tests and ribo-pcr 16s-23s ribosomal rna gen...
the polymerase chain reaction (pcr) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. avipoxvirus (apv) specific dna was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from tehran province. sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...
Structures of pand sd-shell nuclei are studied with the deformed-basis antisymmetrized molecular dynamics method using the Gogny D1S and Skyrme SLy7 forces as effective interactions. By the energy variation with a constraint, energy curves as functions of quadrupole deformation parameter β are obtained. The energy curves for sd-shell nuclei show structure change as a function of β, and suggest ...

Drought is one of the most important factors limiting crop yields around the world. Drought stress in plants, the change (increase or decrease) in the production of plant proteins. This research was carried out using bread wheat genotypes. For evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....
Aims: To generate new medicaments for control and treatment of the parasitic protozoan Toxoplasma gondii. Study Design: Structure similarity search and isostere search was conducted over a broad range of structure categories. Correlation and highest similarity scores were implemented to select the best drug candidates. Place and Duration of Study: University of Nebraska, Department of Chemistry...
