the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
800x600 as a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. today laptops are a great tool for education and learning, work and personal multimedia. millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). over the past several...
Although, the hot solar corona was discovered more than sixty years ago, however, the exact dissipation mechanism that heats the corona is still unknown. Resonant absorption and damping of Alfven waves appear to be one of the major candidates in this respect. The corona is highly structured and inhomogeneous medium, containing a large number of discrete magnetic loops. In this paper a cylindr...
various stresses during life can affect metabolism and brain activities, immune and endocrine systems directly and indirectly, and ultimately, causes animal behavior change. the cellular and molecular level change in neurotransmitter and hormone concentrations led to the functional changes of operating systems in the intracellular organelles. these events cause of course oxidative stress. all ...

the purpose of this study was the relationship between problem – solvi ability with fdi cognitive style of students.the research method was correlation method. for data analysis pearson test was used. statistical society in this research was all the students of alligoodarz city in 1391-92 year.to sampling of statiscal population was used sampling multi-stage random the size of sample selected 2...
In quark potential models, two–body current contributions to baryon magnetic moments arise necessarily to satisfy the continuity equation for the electromagnetic current. On the other hand, the näıve additive quark model predicts the experimental octet magnetic moments to within 5%. We demonstrate that consistently derived two–body current contributions to the octet baryon magnetic moments are ...
Volume integral formulations for solving electromagnetic problems in the frequency domain are proposed. Firstly, it is based on a magnetic flux B and current density J facet interpolation for representing the electromagnetic problem through an equivalent circuit. Secondly, magnetic vector potentials A and electric vector potential T are considered thanks to discrete geometric approach. The form...
The Tera hertz radiation from a finite size superconductor media inside a magnetic field has been investigated. The tera hertz radiation is due to the flux flow motion inside the media. The electromagnetic fields inside the superconductor due to fluxons are calculated and using those fields, the radiation is obtained. In this research, the effects of finite size on the radiated power and signal...
Magnetic brain stimulation used as a method of psychological interventions in the treatment of diseases. This method functions used in the treatment of clinical disorder such as speech and movement disorders caused by stroke, tinnitus, Parkinson's disease, nervous tics. Applications in the field of psychological therapy, it is possible to stimulate specific brain area involved in certain mental...
