What are post graduate courses?
Courses taken after graduating with a college degree. These are used to earn a higher level college degree or a second degree in a different subject.
What is the henrys law constant at 60 degrees Celsius and -10 degrees Celsius?
The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of that gas.
What is the purpose of a dog bone beam?
To reduce the near column beam section stiffness and have lateral flexibility with respect to horizontal seismic loading movements and column beam connections are not overstress.
To have a point of designated failure. You are ensuring that if failure happens, it is in the beam and not at the connection. This is necessary to avoid severe building failure that would be impossible for engineers to predict. This way, we can build for where failure will happen and even though the building would be worthless (say after an earthquake), it ensures that it will still stand and allow people to escape.
What kind of computer software are use in travel agent?
There are several GDS (Global Distributions Companies) in market, that provide software to travel agents. These software provide instant link to all airlines. Most famous companies are Amadeus, Sabre, Abacus, Galileo etc.
Medicine
Gamma rays are used in medicine to kill and treat certain types of cancers and tumors. Gamma rays passing through tissue of the body produce ionization in tissue. Gamma rays can harm the cells in our body. The rays can also detect brain and cardiovascular abnormalities.
Industry
Gamma rays can be used to examine metallic castings or welds in oil pipelines for weak points. The rays pass through the metal and darken a photographic film at places opposite the weak points. In industry, gamma rays are used for detecting internal defects in metal castings and in welded structures. Gamma rays are used to kill pesticides and bugs in food. Gamma rays are also used in nuclear reactors and atomic bombs.
Consumer goods
Gamma rays are often used in the food industry. The radioisotopes preserve foods. Although the rays never come in contact with food, beta radiation kills various organisms, such as bacteria, yeast, and insects.
Science
Gamma rays can be used to detect beryllium. They also played a very important role in the development of the atom bomb.

How do you change the gear knob on a 2001 vw golf mk4?
remove the leather gaitor first, by unclipping it from the bottom of the surround..
pull the gaitor upwards, so it looks like an inside out umbrella,
theres a metal clip at the top, you need to cut that off,
pull and twist up at the same time, it will come off with abit of force
remove the old gear knob fittings, put on your new knob and reverse the whole procedure, using a fresh jubilee clip under the gaitor the hold the knob in place...
drive.. holding your new knob.
IT IS NOT NECESSARY TO CUT THE CLIP. IT CAN BE PRIZED APART ENOUGH TO ALLOW THE KNOB TO COME OFF. JUST USE A POINTY OBJECT TO WIDEN THE CLIP OUT (I SUCESSFULLY USED A FORK).
THEN ON THE REVERSE PROCEDURE, SIMPLY SQUEEZE IT BACK TOGETHER WITH A PAIR OF CRIMPERS OR PLIERS.
What is meaning of VT written in the tail of aeroplane?
Aircraft registration schemes has varied from place to place.aircraft registration schemes has varied from place to place.
Most countries on independence have had a new allocation granted taken from either an existing ITU allocation or the former countries ITU allocation. For example after partition in 1947, India retained the VT designation used by the British, while Pakistan adopted the AP designation from the newly allocated ITU callsigns APA-ASZ.
India registration prefix -VT
India registration pattern - VT-AAA to VT-ZZZ
Why is it important to dislodge any adhering bubbles in the density test?
Bubbles in a substance being evaluated for density will make that material appear less dense. The bubbles are less dense than the substance being evaluated, and they take up volume and add almost no mass. That results in an overall reduction in the mass-per-unit-volume (desity) measurement.
Instrument flanges, (sometimes called Bleed Rings or Sampling flanges), allow a means to measure pressure or obtain fluid samples from a pressurized flange connected line. The instrument flange provides a means of having threaded ports in the line without drilling and tapping the principle equipment in the line (The operator can replace the instrument flange if the threaded ports should become damaged or begin to leak). Instrument flanges commonly have 2, 3, or 4 ports.
The two common forms of instrument flanges, the drilled through type, and the double studded type, function interchangeability.
How do you get a 20af44 toshiba TV to change to channel video 1 without a remote?
There is no way to change the input without a remote :(.
How do you test Resistance Capacitance diodes and transistors on cathode ray oscilloscope?
It is always better to remove a component from the circuit for proper testing but most of the time a resistor can be tested with a DMM set to the appropriate ohm scale, the same with a diode where the DMM is set to diode setting.
A transistor is more complicated, you first have to find the base connector and with your DMM set to diode, NPN Transistor, with negative probe to the base and positive to emitter or collector the smallest reading will be the collector and the slightly higher reading will be the emitter, no reading mean that it can be a PNP transistor then you will need to swap your probes, still no reading or a very low reading will mean the transistor is damaged
In actuality tektronics do make a curve tracer oscilloscope to test active components . But the speed is very limited. So while it may tell you that the part is good or bad it will not tell you how good or how bad it will function in the actual circuit
How do you control hot shortness?
The main reason of hot sortness is sulphur in steel. Therefore, answer of control of hot sortness is to control the sulphur in liquid steel before casting
Which address is more important the physical address or the logical address?
In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the processor forces programmers to consider both.
If you are talking about a virtual environment, however, such as in the 80286 or higher, then the logical address is more important than the physical address, because the logical address is the address of the operand, while the physical address is (somewhat) arbitrarily assigned by the operating system.
Could you give me an example of demand and supply in economics?
first you demand the blowjob, then they supply it!
How many sensors in mouse laser and what are they?
There are three, sometimes 4, if you include the buttons in the sensors.
the other one is a small CMOS camera, it takes pictures of dusts specs, and little abnormalities in the surface, and compares all the pictures.
By comparing them it can track how much it has moved, and provide feedback to the computer, most of these cameras have about 128 pixels.
The door you open before removing the gas cap to fuel your car, truck, van, or suv.
Does there exist an open source software for piping design layout schematics?
See the related link for a list of open source piping software.
