the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
Pendulous lichens dominate canopies of boreal forests, with dark Bryoria species in the upper canopy vs. light Alectoria and Usnea species in lower canopy. These genera offer important ecosystem services such as winter forage for reindeer and caribou. The mechanism behind this niche separation is poorly understood. We tested the hypothesis that species-specific sunscreening fungal pigments prot...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
Suitable alterations in gene expression are believed to allow animals to survive drastic changes in environmental conditions. Drosophila melanogaster larvae cease eating and exit moist food to search for dry pupation sites after the foraging stage in what is known as the wandering stage. Although the behavioral change from foraging to wandering causes desiccation stress, the mechanism by which ...
High-Level Resistance of Nosema ceranae , a Parasite of the Honeybee, to Temperature and Desiccation
maize improvement for high temperature tolerance requires the reliable assessment of parental inbred lines and their combinations. fifteen maize inbred lines were evaluated during 2007 and 2008 in shushtar city (khuzestan province). the inbred lines were planted at two dates: 6 july, to coincide heat stress with pollination time; and 27 july, as normal planting to avoid high temperature during ...
جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...
BACKGROUND Diverse organisms across taxa are desiccation tolerant, capable of surviving extreme water loss. Remarkably, desiccation tolerant organisms can survive years without water. However, the molecular mechanisms underlying this rare trait are poorly understood. RESULTS Here, using Saccharomyces cerevisiae, we show that intracellular trehalose is essential for survival to long-term desic...
the purpose of this quantitative study was to investigate the relation between efl teachers’ self-efficacy beliefs and their success. moreover, the study was an analysis of the teacher age, gender and years of teaching experience, to examine the manner in which these factors relate to teacher self-efficacy as defined by bandura (1997) and teaching effectiveness as evaluated by their own student...
