We offered the new theory of neutron (magnetic isotope) catalysis. For the first time it was shown that the number of neutrons in the atom, which have anomalous magnetic effect, have a great influence on the chemical properties. Our proposed theory of neutron (magnetic isotope) catalysis takes into account the influence of the magnetic field on the catalytic processes. 展开更多

This paper aims to explore and identify the obstacles facing the implementation and applications of IMRI in radiology departments within Jeddah city by analyzing related data received by direct questionnaires and interviews with all the people working in MRI units in Jeddah city and finds that the major obstacle is lacking of awareness of fMRI among medical professionals and their training. 展开更多

The aim of this work is to prove the AMF (anomalous magnetic fields) from the environment cause of AID (autoimmune diseases). The therapeutic possibilities of natural EMF (Earth's magnetic field) is pointed out and how to act to prevent AID is determined. Authors indicate in which magnetic fields the IS (immune system) defends the body. They also explain why, in medical literature, risk factors are mistakenly declared pathogens of AID. The magnetic fields intensity in 20 peoples' beds, suffering from Type 1 diabetes, was measured with proton magnetometer (accuracy of 100 nT). The measurement results are presented on sketches, patients were transferred to the natural EMF, medical condition was monitored, and AID function IS ethiopathology was studied. The correlation between AMF and organ location where AID occurred was determined by measuring. The cells of an organism, formed in natural EMF, are in magnetic balance. When an intruder enters the body, magnetic balance disappears and leukocytes with its MF (magnetic forces) destroy intruders. In the AMF, cells get enlarged MF without magnetic balance, causing IS with its MF to attack own cells, resulting AID. When an intruder enters a tissue, tissue cells and cells of intruders gain enhanced MF. IS with its MF destroys intruders. In the literature (The China Study by T. Colin Campbell), the food is presented as cause of number of diseases. It was found what led to such a misinterpretation. It has been proven that causes of mentioned diseases are only AMF, which can be located in any organ, and with Type 1 diabetes its spread to the whole body with strongest intensity on pancreas. AMF give tissue cells reinforced MF without magnetic balance causing IS to deplete own tissues, resulting AID. IS works perfectly without AMF and risk factors are only a consequence of AMF. 展开更多
