Background : Recognizing effects of static magnetic field (SMF) varying flux density on flora and fauna is attempted. For this purpose the influence SMF upon porphine molecule studied. Methods Computations effect 0.0, 0.1, 1, 10 100 AFU (1 > 1000 T) were performed in silico for changes distribution electron that molecule. HyperChem 8.0 software was used together with AM1 method optimizat...

Influence of external static magnetic fields on solidification, solid phase transformation of metallic materials have been reviewed in terms of Lorentz force, convection, magnetization, orientation, diffusion, and so on. However, the influence of external static magnetic fields on properties of metallic functional materials is rarely reviewed. In this paper, the effect of static magnetic fields...

To evaluate whether cognitive processes, sensory perception, and vital signs might be influenced by static magnetic fields in magnetic resonance imaging (MRI), which could pose a risk for health personnel and patients, we conducted a meta-analysis of studies that examined effects of static magnetic fields. Studies covering the time from 1992 to 2007 were selected. Cohen's d effects sizes were u...

one of the most important advantages of particle simulation as compared to fluid simulation is the capacity for working with and tracing particles. in particle simulations, the test particle method is usually used to get some idea of the behavior of plasma or other substances. in this method, first, a small number of particles are injected into the frame of static electromagnetic fields. then, ...

This study was designed to investigate the effects of applying 1 mT static magnetic field (SMF) during the vitrification process, on the viability of ovarian follicles after vitrification-warming and autotransplantation. The study was conducted in two phases. In the first phase, ovaries of female NMRI mice (6 to 8 weeks old) were randomly divided into three groups: 1- Freshly isolated ovaries f...

Comments on "Is Sperm Motility Maturation Affected by Static Magnetic Fields?" In the paper titled "Is Sperm Motility Maturation Affected by Static Magnetic Fields?" (1), the authors conclude that "sperm production is unaffected because no changes were observed in testicular or epididymal weights after exposure to static magnetic fields." This conclusion, however, is not supported by the data p...

 This study was undertaken to investigate the influence of static magnetic field (SMF) on bone marrow cellular density (BMCD) variation proportionally trabeculae. Female albino Wistar rats exposed with 2.4 ± 0.2 millitesla for 1–4 weeks duration continuously versus 1 h, 2 6 and 8 h/day. Trephine biopsy femurs examined under optical microscope. Data analyzed ImageJ software. Results showed...
