The basic principle for reciprocating engines involves conversion of chemical energy in form of fuel, into mechanical energy. This occurs inside the cylinders of the engine through a process known as four-stroke operation cycle. Intake stroke begins as the piston starts downward travel. When this h...
• The physical background of well logging methods and the response with respect to reservoir characterization (physical principle and primary information from logging methods). • Rules for optimal log combinations, basic equations and m s, and fundamental techniques of log interpretation. I thank...
Fructo-oligosaccharides have been called ‘prebiotics’, as the principle of their beneficial effects is similar to probiotics, i.e. to encourage the growth of beneficial bacteria and inhibit pathogenic species. Fructo-oligosaccharides are utilized by Bacteroides spp. that prevail in healthy caecal ...
Actually how the atmospheric section of climate models work is pretty simple in principle. The atmosphere is divided up into a set of blocks (a grid) with each block having dimensions something like 200 km x 200km x 500m high. The values vary a lot and depend on the resolution of the ...
The basic principle of the structure parameter design is presented, based on the given key parameters. The accuracy of the analytical method is further validated by 3D finite element analysis. Keywords: hybrid magnetic bearing (HMB); radial control windings; cylindrical rotor; equivalent magnetic ...
The equation of the solar absorbing plate temperature can be found by applying the principle of conservation of energy to the control-volume element illustrated in Figure 5. This equation can be written as 𝑄˙𝑠𝑜𝑙𝑎𝑟𝑠𝑢𝑛→𝑝−𝒰𝑐𝑜𝑛𝑣𝑃→𝑎 (𝑇𝑝−...
