The Silicon Controlled Rectifier (‘SCR’) is widely used for ESD protection due to its superior performance and clamping capabilities. However, many believe that SCR based ESD protection is prone to latch-up, competitive triggering, long development cycles and slow trigger speed. This paper provides an overview of the problems and corresponding design solutions available.

Fire-prone landscapes are increasingly being settled. Monitoring this development is an emerging need, and a low-cost method would benefit emergency managers. Existing changedetection methods can be expensive and time consuming when applied to low-density urban change in large, vegetated areas. Nighttime satellite imagery is explored as means for addressing this problem, and a case study is pre...

more than 30% of iran's land is formed from mountainous areas. so each year, landslides cause damages to structures, residential areas and forests, creating sedimentation, muddy floods and finally deposit the sediments in reservoir dams. therefore, for preventing of this damages and expressing the sensitivity rate of hillslopes, landslide hazard zonation is considered in prone areas. the p...

Consumers are taking unprecedented interest in the way food is produced, processed and marketed and are increasingly calling for their governments to accept greater responsibility for food safety and consumer protection (FAO/WHO, 2003). There is growing concern for ways in assessing possible preventive and corrective actions in order to develop new practices to reduce or eliminate different haz...

Radiation-induced skin reactions are an unavoidable side effect of external beam radiation therapy, particularly in areas prone to friction and excess moisture such as the axilla, head and neck region, perineum and skin folds. Clinical studies investigating interventions for preventing or managing these reactions have largely focussed on formulations with moisturising, anti-inflammatory, anti-m...

We propose that guilt proneness is a critical characteristic of leaders and find support for this hypothesis across 3 studies. Participants in the first study rated a set of guilt-prone behaviors as more indicative of leadership potential than a set of less guilt-prone behaviors. In a follow-up study, guilt-prone participants in a leaderless group task engaged in more leadership behaviors than ...

Monocyte-derived foam cells figure prominently in rupture-prone regions of atherosclerotic plaques. Peripheral blood monocytes in culture can produce certain enzymes that degrade extracellular matrix, known as matrix metalloproteinases (MMPs). Lipid-laden macrophages may thus contribute to weakening of extracellular matrix of rupture-prone atherosclerotic plaques. However, the spectrum and regu...

bottom-up approaches have emerged as promising alternatives for generation of organized nanostructures and electronic components. [ 4 ] Bottom-up techniques generally rely upon molecular self-assembly phenomena to produce defi ned structures that could be practically utilized. [ 5 , 6 ] Here, we describe a new bottom-up approach for construction of thin-fi lm TCEs through self-assembly of alkyl...
