In mission critical systems, especially when software is involved, system-level testing is required to be sure the system/software operates correctly. This is often called Verification & Validation. The two are related, but verification is concerned with testing the system functions against the requirements document (which is essential in a critical system). Each requirement should be testable, and all requirements should be tested. Validation is the process of testing that the system and software behaves as it should when interacting with other systems and components.
Verification & Validation is a long, tedious, and expensive process but is essential for mission-critical systems such as where human life or large investment or one-of-a-kind technology is at risk.
The contracts to locate underground utilities are put up for bid on various time lines. Contact your desired companies to determine contract requirements and inquire when the contract will come up for bid. Be aware that the larger companies contract with multiple utility companies in the same area so they can achieve multiple charges while visiting the same site. This allows them to bid cheaper than a single contract only allowing to charge for one utility per visit.

"statified sampling" is a way of getting an 'average' which represents the entire universe, or every thing that exists that somebody wants to count or measure. The entire universe is broken down into groups that dont overlap and a 'sample' is taken from each group. If it is done to the satifaction of statiticians, it can be as accurate, if not more because of the problems of counting and measuring everything, than a total count of measurments.
One of the factors affecting density besides temperature?
Two major factors that determine density (D) are mass (M) and volume (V). Density is related to those factors by the important equation D = M/V.
How has the tsunami and earthquake in japan impacted global supply chains?
Global supply chains hugely depend upon accessibility, timeliness and insuring the tangible products that have to be transported. Tsunami in Japan followed by earthquake led to huge damages to the base-centres of the major supply chain giants which were completely wiped out in Japan. Moreover it hampered the accessibility roads, ports and means of communication. So it has caused huge loss to the base-centres, means of transportation, channels of commuting and communication .
This all depends on the type of field, what a company is trying to advertise, how to get the message out, etc.

Relationship between conductance and viscous flow?
viscosity is inversily change with the conductivity
a bearing is the direction one object is from another object.
A bearing can be taken to a fixed or moving object, so a fixed bearing would be the direction towards a fixed object.

Does a c02 tank have to be used upright?
A CO2 tank does not necessarily have to be upright. It depends if you want liquid CO2 or gaseous CO2. When I purchased a CO2 tank for a specific application, namely, CO2 snow cleaning, I had the option of getting a tank that either had a dipstick, that picked up liquid CO2 from the bottom of the tank, or one that had no dipstick so that it collected gas from the top of the tank. I selected a tank without the liquid pickup. So, my upright tank output gas. However, if I wanted liquid CO2, I would put my tank slightly upside down, and get liquid CO2. It is probably not recommended to run a commercial gas tank in a non-upright position. So, depending on what type of tank you have, and what type of output you want, the answer to your question literally is: depends. For farm and garden use, you are probably seeking gaseous output, and probably have a tank with no dipstick; based on these assumptions, yes, you will need to keep your tank upright.
