Influential People in Medicine The person I chose was Patrice Erna Bath‚ age 74. I chose her because I have working experience in the ophthalmology and I enjoyed my time working in this field. I was curious to see if any women made any inventions. The more I researched about Mrs. Bath the more intrigued I became with her accomplishments. Patrice Bath was born November 4‚ 1942‚ in Harlem‚ NY‚ Bath’s parents were Rupert Bath and Gladys Bath. Her father was born in Trinidad and was the first

theoretical possibility. This low energy form of matter was far from where it is today. Bose and Einstein had done all they could do‚ the rest was a mystery left in our hands. Scene 3—Fast forward a few more years to the 1960s and when the first laser was built. Now scientists and researchers had greater opportunities‚ but still it was limited. Around this time I didn’t know much about Bose-Einstein Condensates‚ I was just beginning to get interested in the topic. It wasn’t until I started school

there are laser beams underwater that‚ in order to protect Atlantis‚ these laser beams shoot out a laser beam to protect the city. In the book The Bermuda Triangle the author Charles Berlitz explains that even if lasers shot planes and ships out of the sky how would they still work even after spending thousands of years underwater (Berlitz‚20). Berlitz has a very good point that the theory of laser beams shooting planes and ships down could not work. Hypothetically even if the lasers lasted all

Distinguish between MYOPIA and HYPEROPIA and outline how technologies can be used to correct these conditions. Hyperopia and Myopia are both vision problems and refractive errors but Hyperopia‚ more commonly known as farsightedness‚ is when a person has trouble seeing things far away but has no trouble seeing them close up‚ Myopia is known as near-sightedness‚ it is when the person can see things far away with no problems but when things are closer to them they have trouble focusing on them and

pattern under the scanning spot. The process for exposing data marks on a recordable optical disk is shown in Fig. 3‚ where an input stream of digital information is converted with an encoder and modulator into a drive signal for a laser source. The laser source emits an intense light beam that is directed and focused onto the surface with illumination optics. As the surface moves under the scanning spot‚ energy from the intense scan spot is absorbed‚ and a small‚ localized region heats

A barcode is an optical machine-readable representation of data‚ which shows data about the object to which it attaches. Originally‚ barcodes represented data by varying the widths and spacings of parallel lines‚ and may be referred to as linear or 1 dimensional (1D). Later they evolved into rectangles‚ dots‚ hexagons and other geometric patterns in 2 dimensions (2D). Although 2D systems use a variety of symbols‚ they are generally referred to as barcodes as well. Barcodes originally were scanned

Electrical Safety in the Perioperative Environment There are numerous ways electricity is employed in the operating room environment‚ such as X-ray machines‚ electrosurgical units‚ monitors‚ surgical table and lights‚ endoscopic cameras and monitors‚ lasers‚ and robotics. Each piece of machinery comes with certain safety precautions when using them in the perioperative environment. Since almost all injuries in the OR result in human error‚ it is important to follow these precautions to ensure patient
