the aim of this study was to investigate the effect of focus of attention on learning dart throwing in mentally retarded children.in this quasi-experimental study, 22 mentally retarded boys (age 10-12 years old) were randomly selected according to iq (50-70) and were assigned to two homogenous attention (internal, external) groups after the pretest and a training session according to the obtain...

swot analysis is used extensively as an assessment and planning method, particularly in tourism planning. however, there are little documentations on application of swot analysis in ecotourism. an assessment on systematic use of swot analysis was carried out in the present study to highlight the applicability of the swot technique in detailed investigations. in this study, based on field survey...

Background: The treatment of open tibial fractures is still an orthopaedic challenge and full of complications. In many cases the use of external fixator that has been known as a non-union machine is obligatory with a high incidence of pin track infection and other complications. The aim of this study was to compare the use of external fixation as a definite method for treatment of open tibial ...

The effective parameters of (5, 0) and (5, 5) single-wall carbon nanotubes during the interaction with carbon dioxide as sensors are determined. The interaction of carbon dioxide  molecules with internal and external walls of the nanotubes is studied using Gaussian 03 coding by density functional theory (DFT) at the B3LYP/6-311G level of theory. CO2 rotation around tube axles vertically and par...

The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...

AB S TRACT The effects of external anions on gating of Na channels of frog skeletal muscle were studied under voltage clamp. Anions reversibly shift the voltage dependence of peak sodium permeability and of steady state sodium inactivation towards more negative potentials in the sequence : methanesulfonate < Cl5 acetate < Br5N03 < S04 < benzenesulfonate < SCN< C104-; approximately the lyotropic...
