Compressors are mechanical apparatus that raise the oil and gas pressure and allow it to be conveyed from the production site, through the supply chain, to the reservoir or the customers. Compressors are grouped into Positive displacement and Dynamic or Kinetic compressors.
The effect of surface functionalisation of zinc doped silica nanoparticles on cellular uptake
Essay - 10 pages - Physics
Nanoparticles are described as particles that have less than 100 nanometre (nm) in a dimension (Khan and Arif, 2012, p. 85). Zinc (Zn) is one of the elements that has been known for its anti-cancer properties (Kim et al., 2013). On the other hand, silica nanoparticle (SiO2 NP) is one of the...
Design of 2, 4 Shell & Tube heat exchanger
Essay - 23 pages - Physics
This project report presents the application of Kern's Method for the optimal design of shell-and-tube heat exchangers. A primary objective in the heat exchanger design is the estimation of the minimum heat transfer area required for a given heat duty, as it governs the overall cost of the heat...
Has the patch clamp given us more information about the initiation of the action potential?
Essay - 6 pages - Physics
An action potential is an electrical discharge that propagates along the length of a cell to transmit a signal. It is initiated by depolarizing the cell via an ion influx until the cell becomes positive in comparison to its external environment, and then rapidly repolarizes to its negative...
Simulation of coal bed methane flow characteristics in coal seams
Essay - 4 pages - Physics
The efficiency of methane released from a coal bed depends on various physical and structural factors of the coal bed. Methane is a gas that is absorbed on the internal surface of coal. The amount of gas that can be produced from a given coal bed depends on various factors such as seam thickness,...
