The functional zonation of liver tissue provides a framework for studying the implantation and growth of metastatic colonies within given zones of the hepatic acini. A very exact method for calibrating the position of metastatic foci in the hepatic acini was made possible by using the succinate-dehydrogenase reaction, which reveals the functional differences of the acinar zones. In mouse livers...

A constrained stochastic weather generator (CSWG) for producing daily mean air temperature and precipitation based on annual from tree-ring records is developed tested in this paper. The principle stochastically generating assumes that temperatures any year can be approximated by a sinusoidal wave function plus perturbation the baseline. CSWG three additional assumptions: (1) In each month, tot...

In the present study the effect of Prandtl number on magneto-convection in a lid driven square cavity with a sinusoidal vertical wall were investigated numerically. The horizontal bottom and top walls are adiabatic. The left and right vertical walls are temperature Th and Tc respectively with Th>Tc. The governing equations along with appropriate boundary conditions for the present problem are f...

the study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. in this study, the propagation of static ...

Introduction: Magnetic nanoparticle (MNP) hyperthermia is a promising cancer treatment approach. It is based on the evidence that by injecting MNPs such as Fe3O4 in the tumor and subjecting them to an alternating magnetic field, they release heat, generating temperatures up to 42°C that can kill cancer cells by apoptosis, usually with lowest damage to normal tissue. In previous...

This correspondence addresses the asymptotic normal distribution of the sample mean and the sample covariance matrix of mixed spectra time series containing a sum of sinusoids and a moving average (MA) process. Two central limit (CL) theorems are proved. As an application of this result, the asymptotic normal distribution of any sinusoidal frequencies estimator of such time series based on seco...

This project involved the study of Brownian motion of polystyrene microspheres in the presence of gravity and a one-dimensional sinusoidal optical potential generated by the interference of two laser beams. An exponential relationship was observed between applied laser power and particle residence time of individual interference fringes. Increasing laser power also revealed a wider distribution...

In this study, hot metal gas forming process of AA6063aluminumtubeis studied with a focus on heat transfer of both fluid and solid phases numerically. An experimental study is simultaneously conducted to validate the numerical method. Some of the most important outputs of the present study, are velocity distribution of fluid inside the tube as well as the fluid in the gap between tube and matri...
