1 Symptoms are due to the effects of excess acetylcholine on nicotinic and muscarinic acetylcholine receptors in the CNS, at neuromuscular junctions, and in the sympathetic, and parasympathetic nervous systems. 2  Nicotinic and muscarinic receptors have different. 3  Functions.
We're taking here about mains voltage (say 120 V or 230 V AC) power supplies with power ranging from a few Watts to several hundred Watts. Switch mode power supplies are everywhere; here are some pictures of their guts. The big high power components and small heat sinks are typical of SMPS. These devices are incredibly reliable, but being very often left powered all the time (even when their load is switched off), they still are the weak link.
Radiant heat pre-heats the fuel in front of the fire, making the fuel even more flammable. For every 10Ë slope, the fire will double its speed. For example, if a fire is travelling at 5 km per hour along flat ground and it hits a 10Ë slope it will double in speed to 10 km per hour up the hill. By increasing in speed the fire also increases in intensity, becoming even hotter. The opposite applies to a fire travelling downhill. The flames reach less fuel, and less radiant heat pre-heats the fuel in front of the fire. For every 10Ë of downhill slope, the fire will halve its speed. Fires tend to move more slowly as the slope decreases.
