We used the MATLAB Program to calculate the mass stopping power and range of alpha particles in biological human body tissues (such as water and the eye lens tissues) at energies between 0.2 and 200 MeV. The Bethe Block formula was used to calculate the mass stopping power, and the simple integration (continuous slowing down approximation) method was used to calculate the alpha particle ranges. Empirical formulae were developed to determine mass-stopping power and ranges of water and eye lens ti...

This paper presents a meticulous analysis of the alterations in the human body’s center of gravity and static friction during movement. The objective is to comprehend the autonomous locomotion of the human body without external propulsion or tension. A wave theory model is proposed to elucidate the fundamental process of human motion on the ground. By considering one foot as a fulcrum, the other foot functions as a lever, generating torque and propelling the forward movement of the human body. T...

On the Earth’s surface the continuous flow of fluids (different gases) is observed. During the preparation of an earthquake, there is the deformation of the environment which changes mass transfer conditions, and changes of this flow arise. These changes are perceived as earthquake precursor. It is the simplest to watch such variations on the flow of the radioactive gas of radon. In work calculation of this precursor in the two-phase environment is made.

Holography has a wide application in medicine, optical computers, scanners among others. Conventional studies on analogue holograms have mainly been conducted on image generation, processing and reconstruction. However, these conditions may vary thus affecting hologram quality. Since convection holography uses photosensitive recording interference patterns in holographic material, there is a need to evaluate aberration or how high intensity of light has been reconstructed. In this paper, we anal...

Exposure of humans to electromagnetic radiations emanating from the antenna of telecom masts and its health effects on humans have been a subject matter for many scientists today. In Ogwashi-Uku, there is no documented literature or generally accepted findings on the health effects of exposure to effects of electromagnetic radiations from the antenna of telecom masts which may be a result of studies not exceeding the world’s permissible limits. This study, therefore, seeks to evaluate the extent...

In this paper, it is studied that the processing mechanism of SiN brittle material in Axial Ultrasound Vibration Assisted Grinding. Search for the relationship between machine tool system and ultrasonic system in AUAG machining, and establish the mathematical model of system matching. The importance of system matching for AUAG machining is verified by the influence of ultrasonic parameters on grinding force and workpiece surface quality. I verify the correctness of the theory. The matching model...

Surface integrals of vector fields play an important role in the solutions of natural science and physical science. The Gauss theorem reduces the difficulty of directly computing surface integrals of vector fields. This paper introduces an approach for the computation of integral surfaces in vector fields and obtains a generalized mathematical expression based on Gauss theorem. Moreover, the computation time is investigated by two classical examples.

Study of gauge symmetry is carried over the different interacting and non-interacting field theoretical models through a prescription based on Lagrangian formulation. And the prescription is capable of testing whether a given model possesses a gauge symmetry or not. It can successfully formulate the gauge transformation generator in all the cases whatever subtleties are involved in it. It is found that the prescription has the ability to show a direction how to extend the phase space using auxil...
