With some design care, a mass flow sensor, pressure transducer and a temperature sensor can provide a fast and accurate method of measuring many difficult volumes.
We derive the Gell-Mann and Low renormalization group equation in the Wilsonian approach to renormalization of massless gφ in four dimensions, as a particular case of a non-linear equation satisfied at any scale by the Wilsonian effective action. We give an exact expression for the β and γφ functions in terms of the Wilsonian effective action at the Wilsonian renormalization scale ΛR; at the fi...
Local mass conservation is of great importance for accurate simulation of fluid flows, especially if the resulting velocity field is to be coupled to a transport equation. Previous work on simulation of saturated groundwater flows have used both mixed finite element methods and discontinuous Galerkin methods to achieve local mass conservation. However, legacy code using a continuous Galerkin fi...
Tip leakage loss introduces major part of losses of the rotor in axial gas turbines. Therefore, the rotor blade tip has a considerable effect on rotor efficiency. To understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). Various blade tip configurations s...
Abstract: Background and Aim: Recruitment of fast twitch muscles cause an increase in muscle mass and strength but these muscles are recruited in high intensities. Old people or persons in rehabilitation process couldn’t do intense training. On the other hand, it has been told that training with blood flow restriction could recruit fast twitch muscles in low intensity. Therefore, we decided to...

In the field of plant nutrition there are many problems which require, for their solution, an understanding of the distribution of accumulated mineral salts between various plant parts. In their discussion of interrelations of salt accumulation with growth and development of the plant body, Steward and Sutcliffe (14) have provided a background for understanding distribution problems. But, they ...
Fuel feeding and inhomogeneity of fuel typically cause process fluctuations in the circulating fluidized bed (CFB) process. If control systems fail to compensate for the fluctuations, the whole plant will suffer from fluctuations that are reinforced by the closed-loop controls. This phenomenon causes a reduction of efficiency and lifetime of process components. Therefore, domain experts are int...
I review the multiphase cooling flow equations that reduce to a relatively simple form for a wide class of self-similar density distributions described by a single parameter, k. It is shown that steady-state cooling flows are not consistent with all possible emissivity profiles which can therefore be used as a test of the theory. In combination, they provide strong constraints on the temperatur...
