conclusions: marital age, and socioeconomic status had a direct association, and hopefulness and marital satisfaction had an indirect one with iranian women’s decision for timing motherhood. therefore, this is the responsibility of policy-makers and healthcare providers to advise women by providing appropriate interventions and facilities. results: the results revealed that among direct pathway...
Idaho is a major malt barley (Hordeum vulgare L.) producer in the United States. Production concentrated semi-arid Snake River Plain region of southern Idaho. Irrigation and fertilizer N applications are two most important managed factors. Research was conducted at University Kimberly & Extension Center near Kimberly, ID, to determine yield, grain quality, characteristics as affected by applica...
A long-term study of four degraded streams in the upper Owens River watershed documented the recovery of riparian habitats and significant improvement in channel morphology in response to grazing strategies, recreation management, and pre-irrigation peak flows. Increased control of livestock distribution, timing of forage use and degree of forage utilization on and near stream banks was designe...
Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...
Agricultural chemical transport to surface water and the linkage to other hydrological compartments, principally ground water, was investigated at five watersheds in semiarid to humid climatic settings. Chemical transport was affected by storm water runoff, soil drainage, irrigation, and how streams were linked to shallow ground water systems. Irrigation practices and timing of chemical use gre...

Research was conducted at Colby and Tribune, KS, from 2018–2020 to evaluate irrigation strategies, hybrid maturity, seeding rate on corn production. Irrigation strategies were a combination of frequency/timing (weekly or bi-weekly) applied pre- post-silking, amounts (1 1.5 inch/week). Hybrid maturities 108- 111-day hybrids planted 25,000 30,000 seeds/a. Average ranged 7.33 12.50 in. 8.41 13.44 ...
w « superintendents in southern Florida have been slow to realize the importance of irrigation in our area because we have what appears to be abundant rainfall. Although southern Florida receives approximately 60 inches of rainfall a year, they are unevenly spaced. We have, in reality, two arid periods: one during July and August, and the other running from November to May, when our courses rec...
In order to study the effects of nitrogen application rate and timing on grain yield, phyllochron and leaf appearance rate of corn (Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili, Ardabil, Iran during 2009 growing season. Nitrogen rates were arranged in main plot w...
the purpose of this study was to examine the effect of self-control feedback on relative and absolute timing through observational and physical practices. participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked, and instructor kr) groups. they practiced a sequential timing task, which required participants to press four keys (2, 6, 8, and 4) respec...
