Optic Neuritis is a condition where the optic nerve, which carries visual information from the eye to the brain, becomes inflamed. Most of the damage is done to the protective myelin sheath that surrounds the nerve, which is vital for good vision. A few symptoms that occur to people who have Optic Neuritis are: distorted color vision, blurriness, pain, and even vision loss. During a routine eye exam, a doctor will look for signs of Optic Neuritis by checking the eye pressure. The eye will be…

He indicates that most of the reports and studies completed regarding cameras causing a reduction in crashes are funded by the Insurance Institute for Highway Safety or researchers funded by them. (Rispo, 2009) While insurance rates do not increase based on red light tickets, they do increase when there is an accident, so insurance companies benefit from red light cameras as well. Rispo interviewed professor and chair of health policy and management of University of South…

Call to Your Tribe For most of my life I have always felt a little out of place, like I am walking around in a humans body, but that’s not who I really am.I am often the guardian of the lost and protector of the week. While this road I am on is not the always the easiest,I understand now that this is the contract I took on when I came to this life. As much as I have tried to fight it, it’s who I am. This road that I have chosen is one that can be quit lonely and this is the part I have…

Evil Dead is a reboot of the original 1981 movie under the same name. We follow a group of friends supporting a friend of theirs in his attempt to help his drug addict sister detox. To detox the sister the friends journey to a cabin in the middle of the forrest. Things go as far as expected as you possibly can imagine and we sit on the edge of our seats waiting to see how the story unfolds. One thing worth noting is that the movie used no CGI at all everything was practical effects. Between…

Taken It was like any other regular day. The chickens were in the hen house and sounded loud, the cows were in the pasture grazing, sleeping, and eating grass, the horses were in the barn getting settled up ready go on our morning ride. As we go through the pasture we get the feeling we are being watched and the feeling has been going on for a couple months. Animals have come up missing, there has been random bones found and then we realize that there are more bones then there should be as in…

These waves are then carried via optical fiber and on reaching the destination site they are demodulated by optical detector (photodiode, phototransistor, photoconductor etc.) to produce electrical output signal. The telecom industry uses fiber optic cable to establish communication between different exchanges such as MSC (Mobile Switching Centre) to BTS (Base Transceiver Station) and between MSC’s as well. Also, it is being widely used instead of Microwave Link to form the trunk network and…

The potential bandwidth of fiber has not been fully utilized and it is already transmitting signals at multiple gigabits per second. Fiber optic cables can go an average of 62 miles versus 1.2 miles that copper can go before the signal needs to be regenerated or boosted. Overall, it is apparent that fiber optics is a more cost effective solution. Fiber optics is non-metallic and is not susceptible to interference, such as electromagnetic interference (EMI), radio frequency (RF) or lightning.…

ECE-669c INDEPENDENT SUDY ON FIBER OPTIC SENSORS Mr. Prasanna M.Thawale School of Computer science and Engineering, California State University Northridge, Northridge-91324. Independent Study On Fiber Optic Sensors  Overview: Term: Fall-2014 Guide: Prof. Nagwa Bekir Topic: Fiber Optic Sensors .  Introduction: Fiber optic sensor since their emergence have been a sector of keen interest for researchers because of their specific and exclusive characteristics thus resulting into the…

Refraction effects are based on the fact that light travels more slowly in a denser medium (Optics). A laser pointer is a low cost laser that is easy to carry around and can be carried in the hand. It is designed to be able to use during presentations to point out areas of the slide. Technically, the word laser is an acronym that stands for "light…

Through out time knowledge about optical illusions has been deepened by many different philosophers and researchers to strengthen the explanations of illusions. Epicharmus and Protagoras, Aristotle, and Plato are only some famous philosophers well known to this day that have contributed their own knowledge about, what actually are optical illusions? Epicharmus is a Greek poet and inventor of Sicilian Comedy during 540 and 450 BC. He was one of the earliest to appreciate the concept of optical…
