Background: Increasing the complexity in modern radiotherapy techniques have increased the delivery time lowering consequently the treatment efficacy. Through simulating the delivery time delay encountered in such techniques, its’ effect on two cancer cell lines and the compensating doses given to prevent such effect was investigated. Materials and Methods: F10B16 and 4T1 cancer cell line...
The Iranian Light Source Facility (ILSF) is a new 3 GeV third generation synchrotron light source which is consisted of several pre-accelerators and a storage ring with the beam current of 400 mA. Based on the main lattice candidate, the storage ring includes of 100 dipoles, 320 quadrupoles and 320 sextupole magnets. To develop fabrication procedures and techniques and to compare the measuremen...

in recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (mri), functional magnetic resonance imaging (fmri), positron emission tomography (pet), or single photon emission tomography (spect) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. in anxiety disorders, recent...
The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...
In many published articles, there is still no mention of quality control processes, which might be an indication of the insufficient importance the researchers attach to undertaking or reporting such processes. However, quality control of data is one of the most important steps in research projects. Lack of sufficient attention to quality control of data might have a detrimental effect on the r...
