Scattering of positronium (Ps) by helium atom has been investigated in a three-Ps-state coupled-channel model including Ps(1s,2s,2p) states using a recently proposed time-reversal-symmetric regularized electron-exchange model potential. Specifically, we report results of differential cross sections for elastic scattering and target-elastic Ps excitations. We also present results for total and d...
The paper belongs to the field of ultrafast optics. Acousto-optic pulse shaping has been studied experimentally for binary intensity modulation in a chirped amplification laser system. Direct time-domain measurement rise/fall time with picosecond streak camera was performed Ti:sapphire regenerative amplifier. It discovered that sign second order dispersion produced by acousto-optic delay line a...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Received: 7 April, 2009 Accepted: 17 June, 2009AbstractBackground & Aims: Antidepressants are very common therapeutic agents in medicine. Design and using new antidepressants have built a new scope for depression treatment. Bupropion is an atypical antidepressant but it is used as an anti-smoke agent widely due to its smoke cessation. Its effectiveness in producing smoking cessation seems inde...
Introduction: Oxidative stress can impair the antioxidant protective capacity of the body, which is associated with decreased capacity of the body's internal defense system. There are some evidences that training and pumpkin seed (PS) consumption by different mechanisms have a protective effect on myocardial tissue by inhibiting oxidative stress. The aim of the present study was to investigate ...

vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
Aim: research on violent behaviors in schools, due to its implications on students educational performance, is among the priorities and instructional policies. Bulling in school is known as a global phenomenon and has a serious impact on students health. The aim of this study was to present the model of Relationship between personality and neuropsychological Coolidge test and bulling behavior ...
The present research studies the performance of Converter Sludge (CL)as a nano-activator of persulfate (PS) in Permeable Reactive Barrier (PRB) as an in-situ technology for leachate treatment.In batch experiments, the acidic conditions (pH = 3) have been the most suitable for removal operations, where COD and NH3 removal efficiencies are 69.15% and 60.96%, respectively. The Box–Behnken design (...
