    Introduction: The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards. Printed circuit boards can be used for just about anything from power dividers to filters. Ring resonators are used to find microwave substrates produced in the ring resonators and can be antennas to circuit boards. The FR4 Ring Resonator is used for…

    to reduce conduction losses and allow it to reach breakeven. One such method would be to protect the grids with magnetic fields so as to prevent the particles from every coming into contacts with the grids directly (Hedditch et al.). This would greatly reduce losses due to conduction and potentially allow breakeven to occur, however as of now these ideas are only hypothetical. As a result, right now fusors are used predominately as neutron sources rather than power sources. This machine uses…

    Maxwell and Faraday- A Brief History of Electromagnetism The field of electromagnetism was established in 1819, twelve years before Maxwell was born. Hans Christian Oersted from Denmark was the first scientist who thought of the possibility that magnetism and electricity were related. He considered such a possibility because of the observations he made during an experiment. He Placed a wire above a compass and passed a current through the wire. He noticed that the needle of compass moved when…

    Energy is the ability to work, more, or elicit change in matter. Energy cannot be formed or impaired; it’s always preserved. Potential energy is a kind of spared energy that objects have because of their position or configuration. Energy comes in many forms, and can be converted from one form to another. Kinetic energy is energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to…

    allowed to test the geometrical accuracy of the system on real patients. The vertebra is easily visualized on the integrated megavoltage imaging system and allows for accurate comparison of field co-ordinates with MRI co-ordinates. The system was accepting patients since around 2012. (Ref 4). The individual MRI-Linac procedures were very reproducible, on average taking 41 min (range 33–44 min) and were well tolerated by the patients. This excludes approximately 15 min of bringing…

    things apart, he can throw cars and move buildings all with the flick of a finger. The Earth itself also happens to be one big magnet, creating a magnetic field, or type of force field, that extends miles beneath the Earth’s surface and into space. Now, split campers into 8 groups of 3 or 4, giving each group two magnets. Have campers hold the magnets close together. What happens? Can they make the magnets stick together or push each other away? Now have them use the magnet to pick up a…

    10754BPhotoelectric separation technology is a method to separate different materials according to the characteristic of the light reflection of material surface and has been used to separate glass of different colours. The colorless glass and colored glass contained in the waste glass should be separated according to various colors. Electric separation is a method using different electrical properties of components in high voltage electric field to separate wastes. This technology is mainly…

    in them being less bright. In this type of circuit the electric current travels through a single path through the circuit, the voltage of the device being used is proportional to the resistance, the current in a circuit is numerically equal to the voltage over resistance, and the sum of each resistance is equal to the total resistance. For parallel circuits, the resistance of the circuit decreases as the amount of parallel branches increases, the sum of all the currents in the parallel branches…

    With this information, the volunteers’ amygdalae lit up. The neuroscientists were able to predict that a volunteer would feel a nonexistent electric shock by “reading their mind” and mapping the brain (Begley 1992). In order to complete the functional map of the brain, technologies and devices were invented with the purpose of extending neuroscientists’ knowledge of the brain. Mapping the Brain not only emphasizes on how the brain is similar to a map with its different regions, but also on how…
