Essay On Optical Fibres

New sciences have also contributed to technology, as in the theoretical preparation for the invention of the steam engine. In the 20th century, innovations in semiconductor technology increased the performance and decreased the cost of electronic materials and devices by a factor of a million, an achievement unparalleled in the history of any technology.”

Furthermore, X-ray of higher energy than required for imaging is used for radiation therapy. The radiation therapy makes use of ionization radiation (and no images) for the treatment of diseases, such as

powered technology once was cutting-edge as well. It played a large role in supporting the

The body has many amazing systems within it. The muscular system is on of the systems that is the most intriguing. Type I, Type IIa, and Type IIb comprise the muscular fiber types within the human body. Type I or Slow-twitch fibers contain mitochondria. These mitochondria use the oxygen that is taken in to create adenosine triphosphate (ATP). ATP fuels muscle contraction. Type I fiber is considered to be aerobic due to the use of oxygen. The slow-twitch muscle fibers are also known as red fibers. This alias is due to the dark red appearance cause by the amount of myoglobin within the fiber. Slow-twitch fibers are the first within the body to be activated due to having a lower activation threshold. They create their own energy source which allows these fibers to sustain force for a longer period of time. The negative aspect is they are unable to create a large amount of force. If the fibers are unable to generate the amount of force that is needed then the fast-twitch fibers will be activated.

X-rays have numerous different effects on the tissues of the body, depending on the time of exposure and energy of the X-ray photons. Best contrast between different tissues is when the photon energy is about 30 keV, for diagnostic purposes. Resulting in the photoelectric effect dominating at this energy. The tissues absorb X-rays and electrons are released. The X-ray absorption depends on the number of protons in the nuclei of the atoms encountered. A high number will attenuate the beam, producing a strong x-ray shadow, enabling for a high quality image of

The word laser is an acronym for, “Light Amplified by Stimulated Emissions of Radiation”, this means that all the lights in a laser have the same wavelength. Within a century of the laser being invented it occupied a major role in scientific research, medicine, industry, and even daily life. Lasers are used in the medicine field for procedures such as, laser eye surgery, heart, stomach, and intestinal surgeries. These procedures laser procedures are said to be harmless. Major factory industries use lasers to cut many things ranging from thin

Thanks to him, the university received Canada’s first betatron in 1948. The betatron made use of magnets to speed up electrons to an energy level of 25-million electron volts. This created powerful X-rays that had the ability to be used for cancer treatment, however extensive usage of the machine was impossible due to the fact that it was too costly, and the X-rays it composed weren't always powerful enough to reach tumors that were deep inside of the

Photons are the particles that are created within the accelerator because os its exposure to radiation. Whenever there is an excessive amount of radiation applied to cells or particles they are either vanished or transformed. If cancer cells were transformed into photons they would be transformed and would change the composure of those cells that have cancer. Since the particle accelrators both produc a high level of energy the energy le

A scientist would need a glass tube with positive and negative electrodes. The tubes were called cathode tubes, and they were common in the late 1890s. The air leaves the glass tube, and a florescent glow is produced when a high voltage runs through the tube. The scientist needs to cover the glowing tube with a heavy, black paper or cardboard. Then the scientist will see the green colored fluorescent light illuminating from the box. This is known as the X-Rays which energizes the phosphorescent materials in the room. The newly discovered ray would pass through objects, and it can cast a shadow of most solid objects. The ray consists of electron passing through the matter underneath the cathode tube. It can pass through human tissues, but it cannot pass through bones and metal

Another experiment that the lab has been working on is trying to build a high powered laser. This experiment is said to help with optical perspective for scientists. The lab is also

Copper will do just fine. Obviously fiber optics will be the better choice, but “beggars can’t be choosers”

According to The American Cancer Society, 43.92% of males and 38% of females have the risk of developing cancer during his/her lifetime (“Lifetime Risk,” 2013). External beam therapy is a common cancer treatment that is distributed from a machine and is focused on the cancer inside the patient (External Beam Therapy, 2014). The treatment is a lot like getting an x-ray only the treatment is more time-consuming and uses a high dosage of radiation which is measured in units called Gray (Gy) (“External Beam Therapy” n.d.). Some of the machines for external beam therapy include linear accelerators, cobalt machines, and orthovoltage X-ray machines (Hopkins, n.d.). The type of machine used on each patient will be decided by the radiation oncologist (Hopkins, n.d.). The machine will not touch the patient and as you read further you will learn it does not hurt, and the radiation cannot be seen, felt, or smelled (“Lifetime Risk”, 2013). External Beam Therapy is an effective and safe treatment plan used to treat cancer.

In this digital age, we rely on technology for all our daily needs. So this article FBI Hunts SF Bay Area Fiber-Optic Cable Cutters written by Richard Adhikari, explains to us how attackers are able to cut fiber optic cables without a motive, which affects many parts of San Francisco. Also, disrupts cable companies. In this article he wants us getting involved to prevent these cuttings from happening around the United States, what is being done to prevent it from happening, and what is the impact of the cables being cut.

Nine Facts About Fiber If you've been looking for a way towards a high octane diet, you'll find fiber to be exactly what you need. Even though research has shown fiber to be powerful, many people aren't taking this nutrient seriously. To help you fuel your health with fiber, here are 10 facts to help.

In terms of education, enormous equipment and expensive yet high quality machines have always surrounded the College of Medical Radiation Technology (or CMRT). However, it is not just about the cost but also about their effectiveness and usefulness for the CMRT students. With these machines, students get to have hands-on activities that prepare them for when they take their internship in hospitals and as future health
