Fact or Science Fiction: Could Lasers become Viable Weapons in Modern World? When I say the word ‘laser’, what is the first thing that comes to your mind? Perhaps, like the majority of people, your brain jumps straight to the science fiction. For decades, since 1898 when HG Wells novel War of the Worlds swept the nation, lasers have been popular within the genre of science fiction. From lightsabers, to ray guns it seems lasers have been imagined as a myriad of different weapons. This…

Literature Review The grow-out house service robot (GOHbot) is designed to perform maintenance within a chicken house in a more sanitary way than that of human maintenance. The purpose of GOHbot’s implementation is to improve flock quality by reducing bacterial contamination without compromising meat yield. The literature discusses disease prevalence in chicken grow-out houses, especially that of Campylobacteriosis, which requires a solution like GOHbot. Multiple sources discuss the unique…

LASIK surgery has been around since the 1990s and over the past two and a half decades, it has become one of the most popular elective surgeries in the world. Surgeons have been working diligently to perfect this surgery and although it is not quite there yet, they have made significant gains in lessening side effects and improving outcomes. These articles contain information about LASIK surgery; including some history, procedure techniques, complications, and patient outcomes. These articles…

Introduction Eye enucleation is surgery to permanently remove the eyeball (globe). The space that remains (socket) after the eyeball is removed will be filled with an artificial eyeball (implant). Muscle tissue will be sewn onto the implant to keep the implant in place and to give it some movement. The natural eyeball may need to be removed because of: Injury. Diabetes. Tumors. Eye disease such as glaucoma. Inflammation or infection of the inner eye (endophthalmitis). A painful, blind eye.…

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 amplification by stimulated emission of radiation," but the word is so frequently used now that it is not capitalized anymore. The radiation is the light that is let out from the laser; this light can be able to be…

looking for laser spine surgery in LA but are still having reservations about a relatively new surgical method, here are some facts about laser spine surgery to give you peace of mind and help you make an informed decision: Fact 1: Lasers only play a small role in the procedure. The main role of the laser is to act in place of the scalpel used in traditional surgery to make incisions. The rest of the surgery is generally carried out with usual methods. Fact 2: Lasers use heat, not light. Lasers…

LITT (Laser interstitial thermal therapy) is a stereotactic-guided minimally invasive ablating technique that involves generating high temperatures thus leading to tissue coagulation, necrosis, and cellular apoptosis (1-3). LITT was initially described by Brown et al in 1983, for the treatment of tumors (5). Later, Sugiyama et al described the utility of this modality in the management of deep-seated brain tumors (6). The concept of using heat energy to treat tumors has evolved to a precise and…
