Family Planning Perspectives pared with 63% of those among Hispanic women and 54% of those among white and other non-Hispanic women.2 The greater prevalence of unplanned pregnancy among low-income women and among black or Hispanic women reflects their lower levels of contraceptive use3 and higher likelihood of contraceptive failure.4 However, it is not clear whether racial and ethnic difference...

cold tolerance is an adaptative mechanism that plants in temperate climates require to survive and grow in suboptimal temperatures.  exposed plant to low temperature produces a myriad of measurable changes in biochemical characters that are often highly correlated with plant cold tolerance.  a key element of cereal adaptation to cold is represented by the capacity for physiological adjustments ...

frost occurrence during plant growth created special conditions to evaluate the effects of planting date on dry matter content and agronomical characteristics of potato cultivars influenced by natural frost in field conditions. a split-plot experiment with three replications was carried out to compare three planting dates, as main plot, from 1 to 21 november with 10 day intervals and four culti...

The evaporator in a frost-free refrigerator typically has more tube rows, but frost deposition reduces along the airflow direction. Correspondingly, fin distribution is thinner upstream rows denser downstream, and good match between achieved to recover capacity loss. However, quantitative design principles of non-uniform are lacking. A quasi-static frosting model established experimentally veri...

It is well known that the characteristics of concrete components greatly affect the durability of high strength/high performance (HS/HP) concrete against frost action. Undoubtedly, precise recognition of this relationship leads &#10to appropriate selection of the type and proportions of concrete components in any particular project. In the current study, the aim is to investigate the possibilit...

The purpose of this study was to investigate the mental representation of cognate and noncognate translation pairs in languages with different scripts to test the prediction of dual lexicon model (Gollan, Forster, & Frost, 1997). Two groups of Persian-speaking English language learners were tested on cognate and noncognate translation pairs in Persian-English and English-Persian directions with...
