Algebraic hyperstructures theory is a natural extension of the classical‎ ‎algebraic structures‎. Because of importance and new viewpoints in this theory, we try to apply this theory to the elementary particle physics and nuclear physics presenting the definitions and the concepts of the algebraic hyperstructures. In this work we intend to use this new branch of mathematics to describe the inte...

background: ct scan and nuclear medicine exams deliver a great part of medical exposures. this study examined professional radiation hazards in ct scan and nuclear medicine workers.   methods : in a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. physical dosimetry was performed for exposed workers. blood samples were ob...

Nuclear level density is one of the most important concepts in nuclear physics; basically, it is the key in dealing with nuclear statistical problems. This quantity plays an essential role in the statistical calculation of reactor physics, astrophysics, researches in the average energy of heavy- ion collision and calculations related to neutron evaporation and other applications. This quantity ...

Introduction: In spite of development in the medical physics technologies, medical physics curriculum for medical students in Iran has not been updated, while teaching medical physics in many universities around the world has been designed based on applied aims. It seems that modern subject teaching in diagnosis and therapy must be alternated with theoretical subjects of medical physics. Method...

  One of the most interesting application of the many-body methods to the nuclear physics is the calculation of the properties of the nuclear matter, especially its binding energy. In this paper, we have studied the influence of Δ -isobar on the properties of the symmetrical nuclear matter using the lowest order constrained variational (LOCV) method with the V28 potential. It is shown that the ...
