The understanding of flavor dynamics is of fundamental importance in elementary particle physics. The study of K and B decays plays a crucial role in this respect. In particular, the precise measurement of the rare kaon decays K → πνν and K L → πνν is regarded as a theoretical ideal for the understanding of CP violation in the Standard Model (SM). These modes provide a clean environment for ext...

In this work, we discuss exclusive semileptonic $B_c$-meson decays: $B_c\to \eta_c(J/\psi)l\nu$ and D(D^*)l\nu$ in the framework of relativistic independent quark(RIQ) model based on an average flavor confining potential equally mixed scalar-vector harmonic form. We calculate invariant form factors representing decay amplitudes from overlapping integrals meson wave functions derivable RIQ model...

sulfur mustard (sm) has been used as a chemical weapon in some conflicts, and many veterans and civilians have been injured thereby. pulmonary, cutaneous, and ocular effects of sm have been frequently reported, although it seems that other organs such as the cardiovascular system are probably also affected. there are a number of studies evaluating the cardiovascular impacts of sm. however, thes...

background: despite almost the three decades passed since the chemical attacks of iraqi’s army against the iranian troops, some veterans are still suffering from long-term complications of sulfur mustard (sm) poisoning, including certain skin complaints specially dryness, burning, and pruritus. we thus aimed to evaluate the skin’s water and lipid content in patients with a disability of >25% du...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

Background and Objective: Temporal lobe epilepsy is hallmarked with neuronal degeneration in some areas of hippocampus and mossy fiber sprouting in dentate area. Considering some evidences on neuroprotective and antioxidant activity of silymarin (SM), this study was undertaken to evaluate the preventive effect of this agent on structural changes in hippocampus of kainate-epileptic rats. Materia...

Sulphur mustard (SM) is an alkylating agent that was first used as a chemical warfare agent during the First World War in 1917. SM is readily absorbed from the skin, respiratory and gastrointestinal tract and is distributed to several organs. SM may act rapidly and persistently upon DNA replicating mechanism of the individual cells during mitosis particularly in the hematopoietic system. O...

This thesis deals with the design, realisation, and testing of the wavelength tunable 1540-nm laser modules that are intended for fibre optic communications. The short external cavity laser uses an electrically controlled silicon micromachined Fabry–Perot interferometer (FPI) device as the tuning element. First, the most common techniques for the diode laser wavelength tuning and applications f...
