the voltammetric behaviour of sulfadoxine (sdn) was studied at a glassy carbon electrode in 0.2 m phosphate buffer solutions using cyclic, differential-pulse (dpv) and square wave voltammetry (swv). the dependence of the current on ph, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of sdn. the oxidation process was shown to be diffusi...

This paper presents a new approach to global clock distribution in which traditional tree-driven grids are augmented with onchip inductors to resonate the clock capacitance at the fundamental frequency of the clock node. Rather than being dissipated as heat, the energy of the fundamental resonates between electric and magnetic forms. The clock drivers must only provide the energy necessary to o...

in the past 25 years, rising of the caspian sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. the main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. the goal of this study is to introduce a proper setback line for th...
