Growing concerns for food security and alleviation of hunger necessitate knowledge-based crop management technologies sustainable production. In this study 13 winter bread wheat genotypes (old, relatively old, modern, breeding lines) were evaluated under three different tillage systems, i.e., conventional (CT; full with residue removed), reduced (RT; chisel retained) no-tillage (NT; retained on...

A numerical model of the NW-Sabalan geothermal field was developed. The model covers a total area of 96 km and extends vertically from variable elevation of 2200-3600m a.s.l to 1,000m b.s.l. The model has 2,595 grid blocks in l4 horizontal layers. The boundary conditions and distributions of horizontal and vertical permeabilities were obtained by trialand-error matching of the initial temperatu...

results no significant difference was observed between the two groups in terms of chronic low back pain; frequency of low back pain in clinical staff was 18% (18 individuals) and in office staff this was 17% (17 individuals) (p < 0.05). chronic low back pain in the clinical group might be related to flexion and extension, twisting, pulling or pushing, carrying, handling of patients, and sitting...

development of new cultivars with high seed yield and desirable characteristics are major goals of lentil program for moderate and semi warm climate of iran. kimiya is a new lentil (lens cultivars medik) cultivar with high-yield, yield satability and adaptability to rainfed conditions. the iranian agricultural research, education and extension organization issued registration for kimiya on 9 au...

Alcohol availability, measured in terms of geographic density of alcohol­sales outlets, is linked to specific patterns of alcohol­related motor vehicle crashes in communities. To curb alcohol­related problems such as violence, traffic crashes, and drinking and driving, community advocates often focus on reducing alcohol availability through modifications of zoning laws and licensing requirement...

The genetic basis underlying inbreeding depression and heterosis for three grain yield components of rice was investigated in five interrelated mapping populations using a complete RFLP linkage map, replicated phenotyping, and the mixed model approach. The populations included 254 F(10) recombinant inbred lines (RILs) derived from a cross between Lemont (japonica) and Teqing (indica), two backc...
