One gram of of the element radium generates approximately 1 curie of activity (Marie Curie, the woman after whom the curie is named, did much of her research using radium). (For an extensive explanation of nuclear materials and nuclear radiation, see How Nuclear Radiation Works.) Let's take...
And while they cost very little, smoke detectors save thousands of lives each year. In fact,it is recommended that every home have one smoke detector per floor. All smoke detectors consist of two basic parts: a sensor to sense the smoke and a very loud electronic horn to wake people...
Go back and re-read the section a few times, it is important to understand this aspect. There is much more to the analysis not shown here – see the Bowling & Grippo paper on the entire analytical method for the Precision Wideband Controller for more info. ...
Medical alert systems are also beneficial for seniors who have limited mobility. Often, these seniors cannot get up and move around quickly in an emergency. With a medical alert system, they can stay in their bed or chair and push a button to get help. It is much safer than moving around...
How Much Propane Does a 30000 BTU Heater Use One-third gallon, aka .33 gallons, per hour. If it ran all day, it would use up to 7.9 gallons. How is this determined? MY LATEST VIDEOS Heat from an open (non-ducted) propane heater comes directly from the open flame. So, for practica...
Even rain is a problem, because it decreases visibility and damages the balloon material (of course, it's not much fun to fly around in wet weather anyway). And while you need a nice wind current to have a good flight, very strong winds could easily wreck the balloon. Pilots also call...

To prevent problems in the future, it's a good idea tohave the furnace tuned uponce a year to make sure everything — particularly the flame sensor — is in good working order. The sensor is much easier to clean when it has only a thin coating of carbon deposits than when it has a...
With stacked sensors, these processing chips have been added to the back of the sensor, essentially creating a ‘stack’ of chips sandwiched together. By stacking them in this way, the distance the pixel values have to travel is drastically reduced, resulting in much faster processing s...
The fuel system might be supplying too much or too little fuel to the mix, meaning that combustion does not occur properly. There might be an impurity in the fuel (like water in your gas tank) that prevents the fuel from burning. Lack of compression: If the charge of air and fuel cann...
