background previous studies have proven the development of white matter hyperintensities (wmh) in methamphetamine and opioid users. opiates and methamphetamines (ma) are the most common addictive agents in iran. the adverse effects of drugs on the cns is of concern to specialists and researchers, and given that the neurotoxicity associated with methamphetamine is greater than opioids, it is hyp...

Widespread arsenic contamination of mining wastewater of Zarshouran (West Azerbaijan province) has led to a massive epidemic of arsenic poisoning in the whole of surrounding areas. It is estimated that approximately all agriculture fields are being irrigated with the water that its arsenic concentrations elevated above the World Health Organization’s standard of 10 parts per billion. A novel ad...

in order to study the effect of intensity and exposure duration magnetic field on wheat (triticum aestivum l.) seed germination an experiment was conducted in laboratory of ferdowsi university of mashhad, iran. the experiment was including 11 treatments as three level of magnetic field intensities (pretreatment of seeds with 50, 100 and 150 mt magnetic field) and three exposure durations (10, 2...

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...

In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. The gluonic penguin structure of hadronic decays is studied thro...

introduction proteins are one of the basic and essential required compounds for life, and the creatures receive it either from a plant or animal origin. it has been reported that the positive effects caused by applying the magnetic field are due to the paramagnetic properties of the cells within the plant, and pigments such as the chloroplast. biophysical methods (magnetic fields, electricity, ...
