As wondrous as it is, the human eye is not without its flaws. It is an imperfect optical system that suffers from a wide array of aberrations, or defects, that have varying impacts on the quality of vision. Like fingerprints, each person’s eye, and its aberrations, is unique. Lower-order aberrations including sphere, cylinder and axis of rotation (astigmatism) are measured using standard ophthalmic instrumentation that has existed for decades. In most cases, these visual defects can be corrected with optical or surgical corrections that provide an acceptable result in terms of patient comfort and visual acuity. Higher-order aberrations, which may account for as much as 20% of the total defects in the eye’s optical system and that are generally regrouped under the “irregular astigmatism” diagnosis, are impossible to diagnose with traditional ophthalmic devices including ophthalmoscopes, retinoscopes or optometers. Although many patients can still achieve perfect visual acuity (20/20), even when these aberrations remain uncorrected, common symptoms including comet, halo and starburst effects can have an important effect on the overall quality of vision. Imagine Eyes’ irx3™ Wavefront Aberrometer overcomes the limitations imposed on less sophisticated diagnostic equipment by applying a completely different approach to ophthalmic diagnosis. By measuring the patient’s entire optical system in one procedure, the irx3 not only provides basic ophthalmic data typically used in prescribing optical corrections but equally an abundance of detailed data on the ensemble of the aberrations present and their effect on the patient’s vision. This data is not only essential for prescribing corrections but also for qualifying patients for different types of optical or surgical corrections. When corrections are applied, especially surgical corrections, comparing the results to the precorrected state is a difficult task. The irx3 can measure with optical or surgical corrections in place, thereby allowing the practitioner to compare the pre and post-corrected results. Even more, the irx3’s proprietary wavefront accommodation assessment allows clinicians to dynamically and objectively evaluate the effectiveness of corrections for presbyopic patients. Correcting for complex aberrations can be a difficult and time-consuming task for both practitioner and patient. Even more, perfect correction does not always mean perfect patient comfort. Oftentimes, doctors must chose to under or overcorrect certain defects in order to provide the patient with optimal visual comfort. The crx1™ Adaptive Optics Visual Simulator is the first in a new generation of adaptive optics phoropters that will revolutionize the way doctors treat both commonplace and complex ocular deficiencies by allowing them to simulate the visual outcome of various corrections before applying them. Retinal diseases are considered a major public health issue. In the US alone, there are over 7 million people that suffer from various forms of retinopathy including diabetic retinopathy, retinitis pigmentosa, macular degeneration and others. Diagnosing and treating retinal pathologies has been a arduous task, largely because of the fact that the eye is an imperfect optical medium that makes obtaining detailed, high-resolution, in vivo images of the retina extremely difficult. Recently, a team of scientists using Imagine Eyes’s adaptive optics technology in combination with OCT techniques were able to acquire exceptional high-resolution, three-dimensional images of retinal microstructures that were, until then, only visible via ex vivo microscopic examination. The leap from diagnosing retinal pathologies to effectively treating them is long. Currently, the major problem revolves around the fact that the focal point of surgical lasers is too large to avoid damaging the healthy tissue in proximity to the diseased cells. In addition to providing doctors the tools they need to visualize the living retina, Imagine Eyes’ technology will, in the future, enable surgical laser manufacturers to reduce the size of the laser’s focal point to that of a single cell. For the first time, doctors will be able to precisely select the cells to be treated while leaving the surrounding healthy tissue intact.

At school we are taught to read, write, and do some arithmetic, which is like math. We need to learn this because then we can read the bible, write letters to people and keep track of our amount of money. Our town is considered lucky to have a schoolhouse because most towns don’t have one. If we didn’t have a school our parents would teach us some things. Then we would probably have the same job that our father has when we grow up. The schoolhouse consists of one room and one teacher. We use the room as a place to learn and in the winter we eat inside and in the summer we eat outside. A wooden stove heats the room and we have to bring in a log to put on the fire. The kids that are in the classroom are from the ages of six to twelve. We all have to learn our lessons by repeating them over and over--boring. This way helps us remember the lessons better. We learn from a hornbook. It looks like a wooden paddle with a paper attached to it with letters, numbers and maybe a verse from the bible on the paper, I am able to hold it in my hand so it is pretty small. My verse is from John 3:16.

the fuses on a motherboard are devices that protect it from electric currents that are too powerful. Each fuse contains a piece of metal inside of itself that melts when the electric current becomes to strong, which stops the electricity from flowing. Motherboards use special fuses called polymeric positive temperature coefficient thermistors; in English, this translates into "a fuse that will reset itself." These fuses protect the motherboard from frying every time a larger amount of electricity surges through the computer power supply Instructions:- hings you~ll need: * Antistatic wrist wrap * Screwdriver 1. * 1 Put on your antistatic wrist wrap. If you wish to check the motherboard fuses and not use an antistatic wrist wrap, touch a grounded piece of metal, such as a doorknob. Move the computer to a place with no carpet flooring. This will protect your motherboard from static electricity. * 2 Turn off your computer and unplug the power cable from the back. * 3 Take your screwdriver and unfasten the screws that are holding up the left side panel on the back of your PC. Remove the side panels. * 4 Lay the computer on its right side. * 5 Look at the motherboard and locate the motherboard fuses; they appear as two metal connectors, which are soldered onto the motherboard, connected by a small bridge, which is the actual fuse. The metal connectors will most likely be a silver color, and the connector will be white. The fuses on a motherboard are never larger than a few millimeters

As our lifestyles become more ~developed~ by the day, so does the damage we do to the environment. Our every move, from watching television, to working at a computer, to taking a flight to our favourite holiday destination harms the environment in one way or the other. Air and water pollution levels are increasing world over by the day. Available information shows that more than 700,000 children under five die from diarrhea in India alone. Never before has the need to use alternative resources, such as wind, solar and nuclear energy been so high. A good time to start would be now!
