Friction stir processing (FSP) has been developed on the principles of friction stir welding (FSW) as an effective and efficien new method for grain refinement and microstructural modification, providing intense plastic deformation as well as higher strain rates than other conventional severe plastic deformation methods. FSP produces an equiaxed homogeneous microstructure consisting of fine gra...

The frequency of haploid production following the inlerspecific pollination of eight tetraploid pot<lto cuhi var~ (Solanum wherosum subsp. IIlberosum) with Solanum phureja clone 1.22 was investigated. A total of 185 haploids were produced with an overall haploid frequency of 3.9 haploids/lOO [ruits. The haploid frequency was affected by the genotype of the maternal parent. Atlantic, NDR60-2, Su...

Epstein-Barr virus (EBV)-induced transformation effi ciencies were quantitated for peripheral blood leukocytes from two patients with xeroderma pigmentosum (XP) and a patient with the related disorder Cockayne's syndrome. By transformed centers or limiting dilution assays, there were no observed differences in transformation efficien cies between XP, Cockayne's syndrome, or normal adult leukocy...

A clonal rat osteogenic sarcoma cell line, UMR 106-06, was used to study the effects of retinole acid (RA) on its growth and morphology. Retinole acid caused a reversible, time and dosedependent inhibition of growth. RA-treated cells were larger, were more adherent to the substratum, and contained fewer mitotic figures. Half-maximal growth inhibition was observed at 10~8 M. Among the naturally ...

heart failure (hf) is a common disease with high health care costs and high mortality rate knowledge of the health-related quality of life (qol) outcomes of hf may guide decision making and be useful in assessing new therapies for population. yet little is known about qol of hf patients in iran. objectives: to assess health related qol of patients with hf with two different instrument and to co...

interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...

background :many studies have reported the increase in strength of the untrained contralateral limb after unilateral training. the aim of this study was to compare the cross education effect in the young and elderly persons.   methods : in this quasi-experimental and pre-post study, 12 young people aged 28.25 ±3.11 years and 12 elderly persons (aged 73.08 ± 5.3 years) participated. the subjects...
