Abstract
Continuous Flight Augers (CFA) require special expertise to construct but done properly they are economical and very successful for areas with inconsistent load carrying capacities. Examples include using CFA pilings for guard rails, highway reinforcement, highway junction improvements and buildings. The CFA pilings are similar to driven and bored piles but offer different advantages when working in good to marginal soils and in projects where the load capacity needs vary. An auger with a hollow tube is used to bore the hole and then when the auger tip reaches the final depth concrete is added as the auger ...

Lubrication is an important function that sustains the life of an engine. Lubricants help in reducing friction and wear of the parts of the engine. Lack of lubrication can lead to corrosion and formation of rust on the engine of an airplane. All engines require lubrication regardless of the frequency of their use. Airplanes that are frequently used can have issues of rust formation and corrosion (EAI, 2015). The idle airplanes have a higher risk of rust formation and corrosion compared to the airplanes that are frequently used. It is easier to lubricate and maintain airplanes that are on ...

I. Introduction
According to the renowned French criminalist Edmond Locard, “every time someone enters an environment, something is added and something is removed from it”. What Locard meant was that in every crime scene, there is some physical evidence left behind that can help identify the unknown suspect (Kalyan & Waghamode, 2014). Since people commit crimes one of the most common types of physical evidence that is left behind id biological material or materials produced by the human body. Indeed, one of the oldest forms of biological evidence that criminalists and police have used in crime investigations is the fingerprint.
