A recent international group of scientists identified fatigue as “the largest identifiable and preventable cause of accidents in transport operations (between 15 and 20% of all accidents)‚ surpassing that of alcohol or drug related incidents in all modes of transportation. Official statistics often underestimate this contribution.” (Rosekind‚ 1993). Fatigue engendered by sleep loss and circadian disruption can degrade all aspects of human capability. Significant reductions in operator performance

Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient

Many muscle properties change during fatigue including the

I had so many questions going through my head‚ but I only had 10 minutes to hurry up and get ready. Hair‚ teeth‚ makeup‚ and soccer gear that’s everything I thought to myself.
