language learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Natural mortality of Trachurus novaezelandiae and their size selection by purse seines off south-eastern Australia
The natural mortality (M) and purse-seine catchability and selectivity were estimated for Trachurus novaezelandiae, Richardson, 1843 (yellowtail scad)-a small inshore pelagic species harvested off south-eastern Australia. Hazard functions were applied to two decades of data describing catches (mostly stable at a mean +- SE of 315 +- 14 t p.a.) and effort (declining from a maximum of 2289 to 642...
متن کاملAge at Natural Menopause and Stroke Mortality
Background and Purpose—Young age at natural menopause has been related to increased cardiovascular mortality, but few studies have examined the relationship with stroke risk specifically. Methods—In a cohort of 19 731 Norwegian women, we analyzed the relationship between age at natural menopause and stroke mortality. A total of 3561 women died of stroke during the 37-year follow-up from 1961 th...
متن کاملProtective effect of natural honey applied during ischemia and reperfusion on infarct size in ischemic heartheart
Introduction: In the current study, protective effect of natural honey applied during ischemia/reperfusion (I/R) was studied on infarct size in ischemic heartheart. Methods: Ischemic hearthearts (n=8 per group) were mounted on a Langendorff apparatus at constant pressure then subjected to 30 min regional ischemia followed by 120 min reperfusion. In control group, the hearts were perfused by ...
متن کاملShould hunting mortality mimic the patterns of natural mortality?
With growing concerns about the impact of selective harvesting on natural populations, researchers encourage managers to implement harvest regimes that avoid or minimize the potential for demographic and evolutionary side effects. A seemingly intuitive recommendation is to implement harvest regimes that mimic natural mortality patterns. Using stochastic simulations based on a model of risk as a...
