What is the difference between DSC and TGA?
What is the difference between DSC and TGA? Differential scanning calorimetry (DSC) examines the temperature difference between a sample in a small pan and an empty pan when both are heated together. Thermogravimetric analysis (TGA) places a small sample into a balance that is enclosed in an oven. What TGA can tell you? The data […]
What did FEMA do wrong in Hurricane Katrina?
What did FEMA do wrong in Hurricane Katrina? Perhaps the most appalling aspect of the federal response to Katrina was that officials obstructed private relief efforts, as these examples illustrate: FEMA repeatedly blocked the delivery of emergency supplies ordered by the Methodist Hospital in New Orleans from its out-of-state headquarters. What did the Post Katrina […]
How much humidity does an evaporative cooler add?
How much humidity does an evaporative cooler add? when using an evaporator cooling technique, each time you drop the temperature 20 degrees you double the relative humidity. If you start out with 95 degree F and a relative humidity of 25%, the swamp cooler can get you 75 degrees and 50% relative humidity. At what […]
What are five advantages of work sampling over time study methods?
What are five advantages of work sampling over time study methods? Advantages of Work Sampling: (1) It is a cheaper technique than time study and production study. (2) Only one analyst can perform work sampling study of many activities. (3) Observers does not require much training. (4) It is more useful in non-repetitive and indirect […]
How does chlorine destroy ozone?
How does chlorine destroy ozone? When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created. How does the ozone layer protect […]
What is the work breakdown structure of a project?
What is the work breakdown structure of a project? A Work Breakdown Structure (WBS) is a deliverable-oriented hierarchical decomposition of the work to be executed by the project team to accomplish the project objectives and create the required deliverables. A WBS is the cornerstone of effective project planning, execution, controlling, monitoring, and reporting. What is […]

How do you calculate ultimate tensile stress?
How do you calculate ultimate tensile stress? Divide the the applied load by the cross-sectional area to calculate the maximum tensile stress. For example, a member with a cross-sectional area of 2 in sq and an applied load of 1000 pounds has a maximum tensile stress of 500 pounds per square inch (psi). What is […]
What is asynchronous counter?
What is asynchronous counter? Asynchronous counters are those whose output is free from the clock signal. Because the flip flops in asynchronous counters are supplied with different clock signals, there may be delay in producing output. The number of output states of counter is called “Modulus” or “MOD” of the counter. When designing a mod […]
