Mix cropping of alfalfa (Medicago sativa) and annual ryegrass (Lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. In this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...

Standard-length porous-coated tapered femoral stems perform exceedingly well in primary total hip arthroplasty (THA) at long-term follow-up. Nevertheless, there are multiple reasons to strongly consider the relatively new concept of short tapered stems. First, there is already a wide variation in the lengths of "standard" components and the ideal length is unknown. The goal of tapered stems is ...

An uncemented stem has been used successfully in total hip arthroplasty for 2 decades, and some implants have been updated. The authors have used second-generation uncemented proximal porous coating stems, the Echo Bi-Metric Full Proximal Profile stem (Echo FPP; Biomet, Warsaw, Indiana) and the Echo Reduced Proximal Profile stem (Echo RPP; Biomet). This article reports short-term outcomes with ...

Asparaginase was extracted from plant parts of Pisum sativum subspp. Jof collected from a field crop. Asparaginase activity was detected in seeds, stems and leaves extracts. Enzyme activity was higher in seeds extracts (30.0 U/ml) compared with leaves extracts (26.4 U/ml) and stems extracts (16.1 U/ml), respectively. Optimum conditions for the activity of crude asparaginase extracted from plant...

This article studies Young Avestan forms in -āiš (formally instr.pl.m./n. of a-stems), nom.-acc.pl.f. ā-stems) and -īš nom.pl.f. ī-stems) that are used contexts where neuter nom.-acc.pl. / collective (a-stems) (consonantstems) expected. It is argued these -āiš, , secondarily created pluralizations original collectives reaction to the syntactic change according which their singular verbal concor...

Progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. A linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. The opposite femur was used as the control measurement. Bone mineral density was unchanged at two mo...

analysis of genetic diversity in germplasm collections can facilitate reliable classification of accessions as well as identification of subsets of core accessions with possible utility for specific breeding purposes. to investigate the pattern of genetic variation in tall fescue (festuca arundinacea schreb) germplasm, a field experiment was accordingly conducted. seeds of 25 iranian, 11 hungar...

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 m...
