this study was designed to investigate the impacts of teachers self-disclosure on students foreign language classroom anxiety, attitude to english language learning and their achievement scores at the end of the term. there were 48 female learners of intermediate level. they were not randomly selected. there were one experimental group with 21 students and one control group with 27 students.the...
Partial shadowing has been identified as a main cause for reducing energy yield of grid-connected photovoltaic systems. The impact of the applied system configuration on the energy yield of partially shadowed arrays has been widely discussed. Nevertheless, there is still much confusion especially regarding the optimal grade of modularity for such systems. A 5-kWp photovoltaic system was install...
www.aafp.org/afp Volume 87, Number 10 ◆ May 15, 2013 Among adults with atrial fibrillation, the annual rate of stroke ranges from 1 to 20 percent, depending on comorbidities and the patient’s history of cerebrovascular events. Because of the risk of bleeding associated with antithrombotics such as warfarin (Coumadin) that are used to reduce the incidence of atrial fibrillation–related stroke, i...
Abstract The aim of this study was to investigate the role of working memory capacity and errorless and errorful practice on the learning the relative timing was a motor task. 50 Participants based on were selected aged 22±4 years as accessible samples randomly assigned to one of four groups (errorless low working memory capacity, errorful low working memory capacity, errorless high working me...
In this paper, in addition to some elementary facts about the ultra-groups, which their structure based on the properties of the transversal of a subgroup of a group, we focus on the relation between a group and an ultra-group. It is verified that every group is an ultra-group, but the converse is not true generally. We present the conditions under which, for every normal subultra-group of an u...
to evaluate the effect of different light intensities on the degree of conversion (dc) of dual-cured resin cement at different depths of translucent fiber posts.thirty translucent fiber posts were randomly assigned into three (n=10) groups. they were cemented in the simulated canal spaces using duo-link dual-cured resin cement. the cement was light-cured under 600, 800 and 1100 mw/cm(2) light i...
This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...
In this article we study the arcwise connected component in the Pontryagin dual of an abelian topological group. It is clear that the set of continuous characters that can be lifted over the reals is contained in the arcwise connected component of the dual group. We show that the converse is true if all arcs in the character group are equicontinuous sets. This property is present in Pontryagin ...
BACKGROUND AND OBJECTIVES The aim of this study was to examine the anti-proliferative and anti-inflammatory effects of a stent coated with abciximab and alpha-lipoic acid (ALA) in a porcine coronary overstretch restenosis model. MATERIALS AND METHODS A total of 10 pigs were randomized into two groups (10 pigs, 10 coronaries in each group) in which the coronary arteries were stented with a dua...
BACKGROUND Studies with functional and applicable methods and new cognitive demands involving executive function are needed to improve screening, prevention and rehabilitation of cognitive impairment and falls. OBJECTIVE to identify differences in gait, dual task performances, and history of falls between elderly people with preserved cognition, mild cognitive impairment and mild Alzheimer's ...
