abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
Dithranol is a potent agent in treating psoriasis but its adverse effects on intact skin have limited its usage. There are many proposed mediators for its adverse effects including prostaglandins, histamine, platelet activating factor and free radicals. In this study we examined the effect of different agents (diazepam, terfenadine, indomethacin and garlic extract) on dithranol-induced skin dam...
