Chapter 4‚ page 1 4 Nuclear Magnetic Resonance Pieter Zeeman observed in 1896 the splitting of optical spectral lines in the field of an electromagnet. Since then‚ the splitting of energy levels proportional to an external magnetic field has been called the "Zeeman effect". The "Zeeman resonance effect" causes magnetic resonances which are classified under radio frequency spectroscopy (rf spectroscopy). In these resonances‚ the transitions between two branches of a single energy level

Role of Folic Acid in Neural Tube Defects | A genetic‚ environmental‚ and nutritional approach to better understanding of abnormal conditions | | Darshak Joshi | July 6th‚ 2013 | | Introduction Human birth defects‚ today‚ continues to be a highly investigated research. There remain many convoluted combination of genetic and environmental factors that can cause birth defects. While some conditions are easily repaired through surgery‚ neural tube defects (NTDs) present problems

Magnetic resonance imaging (MRI) is a type of scanner that uses strong magnetic field and radio waves to produce complete images inside the body. An MRI scanner is a large tube that contains strong magnets. The patient lie inside the tube during the scan. The MRI scanner is used to observe almost any part of the body including the brain and spinal cord‚ bones and joints‚ breasts‚ heart and blood vessels and internal organs such as the liver‚ womb or prostate gland. The results of an MRI scan can

MAGNETIC RESONANCE IMAGING Magnetic resonance imaging (MRI) has developed into one of the most versatile techniques in clinical imaging and biomedical research by providing non-invasively high resolution‚ three-dimensional anatomical and contrast-enhanced images of living tissue. The two most common groups of contrast-enhancing agents are gadolinium-based complexes and magnetic nanoparticles. Both types of contrast agents shorten locally the relaxation time of bulk water protons via rapid exchange

There are two devices that are most commonly used and each device has specific indications and contraindication. 2 Research question This study was done to answer the following question: Are licensed practitioner’s beliefs about airways (oral ET-tube and LMA) consistent with the current printed information and do they report using the airways in a similar manner? To answer this question‚ we first needed to know what practices the current published studies have suggested will have better out-comes

endotracheal tube you will prefer RAE‚ flexomettalic or mcintosh? What are the problems associated with these tubes? Ans- Ideal ET Tube is south facing RAE (Ring Adair Elwin) tube fixed in center over the lower lip. RAE Endotracheal Tubes are designed to conveniently position the anesthesia circuit out of the surgical field. Problem- Difficult to pass Suction catheter. Fixed curvature hence more chances of endobronchial intubation or inadvertent extubation. Flexometallic tubes- Inner diameter of tube decreases

only 4 miles long (6.5 kilometers) running from the west of London to the city in the east. It was not very deep and steam trains were used. Then deeper tunnels were built and in 1890 the electric railway was opened. Londoners called this system the Tube and it is still a very popular name for the London Underground. Some deep stations of the London Underground were used for protection of people during the Second World War. A great number of people use the underground system every day because it connects

Magnetic Resonance Imaging (MRI) is a medical imaging technology that uses strong magnetic fields and radio waves to create graphic images of the body’s anatomical and internal structures (1). MRI relies primarily on the protons in fat and water molecules of the body‚ as these protons respond to the static magnetic field created in ways that allows for a high quality image to be generated (2). These images contrasts specific tissue and different anatomical structures. For example‚ MRI can reveal
