We present the concept and results of an investigation all-optical vector-magnetic-field sensor scheme developed for biological applications such as nonzero-field magnetoencephalography magnetocardiography. The differs from classical two-beam Bell-Bloom in that detecting laser beam is split into two beams, which are introduced cell orthogonal directions, ratio amplitudes magnetic resonance sign...

The aim of this work is to develop a wireless local area network (LAN) between different types of users (Radiation Oncologists, Radiological Physicists, Radiation Technologists, etc) for efficient patient data management and to made easy the availability of information (chair side) to improve the quality of patient care in Radiation Oncology department. We have used mobile workstations (Laptops...

We read with great interest an article by Shokri et al. entitled "Effects of Wi-Fi (2.45 GH z) exposure on apoptosis, sperm parameters and testicular histomorphometry in rats: a time course study" that is published in the latest issue of the Cell Journal (Vol.17, 2015: 322-331). In this article, Shokri et al. have presented their findings obtained in an experiment on an animal model. These rese...

Radiofrequency radiation (RFR), e.g. electromagnetic waves emitted by our cell phones and Wi-Fi, are referred to as non-ionizing. This means that in contrast to the ionizing radiation, which does induce ionization of water and biologically important macromolecules, RFR does not have a capacity for such effects. Unlike, for example X-rays, the energy of RFR is not enough to break electrons off t...

An optical breakdown caused by a nanosecond laser beam focused into a gaseous medium forms a laser spark in the given gaseous environment. The most likely processes triggered by the spark are those of radiation chemistry forming radicals and more complex molecules from originally simple gas components. Owing to its high energy density, the laser spark is an ideal instrument to simulate the ener...

Recent progress in kilojoule-scale high-intensity lasers has opened up new areas of research in radiography, laboratory astrophysics, high-energy-density physics, and fast-ignition (FI) laser fusion. FI requires e cient heating of pre-compressed high-density fuel by an intense relativistic electron beam produced from laser–matter interaction. Understanding the details of electron beam generatio...

the purpose of this paper is to obtain necessary and suffcient conditionsfor existence approximate fixed point on geraghty-contraction. in this paper,denitions of approximate -pair fixed point for two maps tα , sα and theirdiameters are given in a metric space.
