STUDY OBJECTIVE Sleep apnea (SA) may promote hearing impairment (HI) through ischemia and inflammation of the cochlea. Our objective was to assess an independent association between SA and HI in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) participants. METHODS We used data from the HCHS/SOL, a multicenter population-based study of self- identifying Hispanic/Latinos 18- to ...
Background: Purpose of the study is to evaluate field-in-field (FIF) and sliding-window intensity modulated radiation therapy (SW-IMRT) treatment plans in terms of homogeneity index (HI), conformity index (CI) and normal tissue doses for organs at risk (OAR) in patients with endometrial carcinoma along with deriving a new expression for CI. Materials and Methods: Four different FIF plans with d...
Thirty soybean cultivars from different maturity groups were evaluated in a randomized complete block design with four replications in Research Station of College of Agriculture at Tehran University in Karaj in 2004. The purpose was to determine genetic relationship of some important agronomic traits related to seed yield. Analysis of variance showed that there were significant differences amon...

The current research was carried out to investigate grain yield and components and their genetic diversity and heritability of some important agronomic traits, in 19 chickpea genotypes, based on a randomized complete block design with 3 replications in Research Field of Bu-Ali Sina University, Hamadan, Iran in 2011-2012 growing seasons. The ANOVA results showed that, there were highly significa...
Seed yield of alfalfa (Medicago sativa L.) is important in determining the effective distribution of new cultivars to farmers. Many genetic and environmental factors affect seed yield. This study was conducted to explain seed yield variation induced by either environmental conditions or cultivars. We analyzed seed yield, aboveground phytomass, harvest index, and seed yield components for a set ...
in order to investigation of nitrogen fertilizer split application effect on quantity yield and grain quality of rice varieties, an experiment was carried out based on rcbd design as split plot experiment in three replications in langroud in 2006. mainand sub factor were variety (hashemi and bahar 1) and five nitrogen fertilizer split application (split of 150 kg.ha-1 n at transplanting, stemmi...
proper use of water resources in arid and semi-arid regions is important and vital. this study was conducted to evaluate the effect of irrigation scheduling by various methods on crop yield and water use efficiency (wue) by wheat, and determining suitable irrigation-scheduling method for irrigation of wheat in saeedabad, tabriz. a field experiment was conducted with 10 irrigation treatments (i1...
The historical sediment record of Lake Sonachi (Kenya) was used to study the influence of lake depth and mixing regime on patterns of sedimentation in a small, fluctuating tropical soda lake. Lake Sonachi last desiccated completely in the early nineteenth century and has fluctuated between 3and 18-m lake depth over the past 115 yr. A freeze-core of offshore sediments describes recent lake histo...
