The effects of density and food on remating were investigated using Drosophila melanogaster. The frequency of remating was unaffected by density for some combinations of fly strains but was reduced at low relative densities for other combinations. Until females had used most of their stored sperm, remating was less likely when food was absent or contact with food was prevented. Food availabilit...

Background and Aim: The frequency of patient complaints, and subsequent lawsuits filed by patients against dentists has been on the rise in the recent years. Given the importance of being aware of these issues and preventing them, the purpose of this study was to assess the frequency of dental complaints filed in the Medical Council Organization of three cities of Mazandaran Province (Sari, Bab...

The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...

The propagation of torsional waves in a prestressed fiber-reinforced half-space under the effect of magnetic field and gravity has been discussed. The problem has been solved analytically using Whittaker function to obtain the exact solution frequency equations. Numerical results for stress, gravity and magnetic field are given and illustrated graphically. Comparisons are made with the results ...

We have developed a second-harmonic-generation (SHG) microscopy system whose electric filed at the focus is controlled three-dimensionally in order to observe three-dimensional molecular orientation with high spatial resolution. Figure 1 shows the developed system. The system consists of a femtosecond laser to induced nonlinear optical phenomenon (SHG), a parallel-aligned liquid-crystal spatial...

Gravity data inversion is one of the important steps in the interpretation of practical gravity data. The inversion result can be obtained by minimization of the Tikhonov objective function. The determination of an optimal regularization parameter is highly important in the gravity data inversion. In this work, an attempt was made to use the active constrain balancing (ACB) method to select the...
