background: although percutaneous coronary intervention (pci) is an excellent therapy for coronary artery disease, there is a paucity of information on the efficacy of pci in improving diastolic function, especially in iran. because of the high prevalence of left diastolic dysfunction in coronary artery disease patients and its probable progression to heart failure, an evaluation of the role of...

In this paper, a mathematical model for symmetrical multi-layer sheet rolling, in which the layers are unbounded before rolling, by using the upper bound method and stream function theorem is proposed. Using this model, we can investigate the plastic deformation behavior of sheets at the roll gap during rolling. Effect of various rolling conditions such as initial and final thickness and flow s...

the present study aimed to investigate two numerical solutions of the navier-stokes equations. for this purpose, the mentioned flow equations were written in two different formulations, namely (i) velocity-pressure and (ii) vorticity-stream function formulations. solution algorithms and boundary conditions were presented for both formulations and the efficiency of each formulation was investiga...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...

The statistics of velocities in the cellular automaton model of Nagel and Schreckenberg for traffic are studied. From numerical simulations, we obtain the probability distribution function (PDF) for vehicle velocities and the velocity-velocity (vv) covariance function. We identify the probability to find a standing vehicle as a potential order parameter that signals nicely the transition betwee...

A new approach to consider balance dynamics for modelling slow vortical motion is suggested within the rotating shallow water primitive equations. Instead of a traditional approach using divergence and ageostrophic vorticity as fast variables, the velocity is exactly expressed as a sum of the gradient part, described by a Bernoulli function, and the rest, an agradient part, proportional to the ...

Using constrained simulations of the local Universe for generic cold dark matter and for 1 keV warm dark matter, we investigate the difference in the abundance of dark matter halos in the local environment. We find that the mass function within 20 hMpc of the Local Group is ∼ 2 times larger than the universal mass function in the 10 − 10 hM⊙ mass range. Imposing the field of view of the on-goin...

there are various ways for estimating velocity of money in economic literature and each has its own specific weaknesses and strengths. particularly, since a great deal of financial innovations and changes have recently taken place affecting the velocity of money, many traditional methods can no langer calculate the equilibrium velocity of money, and they are no longer dependable from the econom...

the base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...
