rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
This study was carried out in order to determine the more suitable seedling age on rice cultivars in Chaparsar Rice Research station of Mazandaran province in 2009. This experiment was laid out as split plot in a randomized complete block design with 3 replications. The main plots were seedling age with four levels (20, 33, 37 and 40 days) and sub plots were rice cultivars (Hashemei, Khazar, hy...

This study was carried out to determine the effect of pre-incubation storage periods on egg weight loss, embryonic development and hatchability of hatching pullet eggs. Three hundred eggs were used for this experiment. The eggs were sourced on five different days (sixty eggs per day) at three days interval (day 0, 3, 6, 9, and 12) and weighed. The sixty (60) eggs collected on each day were subd...
Developmental times and survivorship of tarnished plant bug nymphs, Lygus lineolaris (Palisot de Beauvois), and longevity and reproduction of adult tarnished plant bug adults reared on green beans were studied at multiple constant temperatures. The developmental time for each life stage and the total time from egg to adult decreased with increasing temperature. Eggs required the longest time to...
