1. Outline of Basic NMR Principles Nuclear magnetic resonance (NMR), as all spectroscopic methods, relies upon the interaction of the sample being examined with electromagnetic radiation, here in a range of radio frequencies (11000 MHz). To absorb a photon of electromagnetic radiation, the transition energy ΔEsample due to the interaction of a nuclear spin in the sample with a magnetic field mu...

i ntroduction: liposuction using laser is now one of the most common cosmetic surgery. this new method has minimized the disadvantages of the conventional liposuction including blood loss, skin laxity and long recovery time. benefits of the new liposuction methods which include less trauma, bleeding and skin tightening prove the superiority of these methods over the traditional mechanical metho...

We participate in the Atmospheric Radiation Measurement (ARM) Program with two objectives: 1) to improve general circulation model (GCM) cloud/radiation treatment with focus on cloud vertical overlapping and layer cloud optical properties, and 2) to study the effects of cloud-radiation climate interaction on GCM climate simulations. This report summarizes the recent findings in sub-grid scale v...

Understanding hadronic multiparticle production is important for deriving the composition and energy spectrum of primary cosmic rays from air shower measurements at high energy. In this article, predictions of hadronic interaction models are discussed, emphasizing uncertainties and constraints due to model assumptions and accelerator measurements. The sensitivity of shower observables to model ...

Two or more factors can simultaneously make their combined effects on the biological objects. This study has focused on theoretical approach to synergistic interaction due to the combined action of radiation and another factor on cell inactivation. A mathematical model for the synergistic interaction of different environmental agents was suggested for quantitative prediction of irreversibly dam...

Background: Diazinon is one of the most common pesticides in the world playing a similar role to radiation and it could cause DNA breaks and genetic effects.Objective: In this study, radiosensitivity of a lymphoblastic cell line pretreated by Diazinon was investigated. Material and Methods: In this case-control study, the human lymphoblastic T-cell line was divided into 6 groups bas...

The main features of radiation by relativistic electrons are well approximated in the Weizsäcker-Williams method of virtual quanta. This method is best known for its application to radiation during elementary particle collisions, but is equally useful in describing “classical” radiation emitted during the interaction of a single relativistic electron with an extended system, such as synchrotron...

Physics is the science that studies the interaction between matter and energy. This discipline studies the general properties of bodies, the forces that modify the transfer of energy and the interaction between particles. Physics now has many branches, and one of them is the Biomedical Physics. Biomedical Physics in Medicine applies the principles and methods of physics. This will generate new ...

Through full-vectorial simulations and analytical models, we investigate the role of radiation and surface plasmon polaritons (SPP) in the optical interaction between a nano-slit and a parallel nano-groove on a metal surface. We quantitatively confirm the radiaton as the interaction mechanism in perfect electrical conductors (PEC), and verify the role of radiation and SPP in the slit-groove int...
