U OF T PROFESSORS DEVISE BETTER WAY TO TEST SIGHT IN BABIES In a darkened room at Toronto's Hospital for Sick Children, a baby, its head dotted with electrodes, sits in its mother's lap and watches flashing black and white checkerboards and stripes on a television screen. Soon after the test, doctors will know if the child can see and how well it can see. The testing procedure, which involves measuring brain wave activity pro

Bacterial resistance is a problem that has profoundly impacted the medical community. Bacterial resistance results when bacteria become resistant to individual antibiotics through the development of specific defense mechanisms which render the antibiotic ineffective. This problem has become evident in recent years as numerous cases have been reported in which antibiotics are not effective against the bacteria that they have fought off for years. The recent troubles with bacteri

1. Introduction: This report is the first stage of the design, construction and testing of a balsa wood structure. In April, the design will be tested against classmates' designs, where the design with the highest load/weight ratio wins. The information gained from this report will be used in the construction of the structure. The report is composed of two sections. The first is an evaluation of material properties of balsa, glues and different joint conf

Daniel Bernoulli was born into a family of mathemeticians on February 8, 1700. He was the only person in his family to make an impressive mark on physics. Bernoulli became a Swiss physicist and mathmatician who made enourmous contributions to the world of physics. He uncovered many significant phenomena in hydrodynamics, and in 1738, published his most famous work, Hydrodynamica, which was a study of equilibrium, pressure, and velocity of fluids. He proved t

It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two types of models: Big Bang and Steady State. However, through many observational evidences, the Big Bang theory can best explain the creation of the universe. The Big Bang model postulates that about 15 to 20 billion years ago, the universe violently exploded into being, in an event called

Picture this. A man is involved in a severe car crash in Florida which has left him brain-dead with no hope for any kind of recovery. The majority of his vital organs are still functional and the man has designated that his organs be donated to a needy person upon his untimely death. Meanwhile, upon checking with the donor registry board, it is discovered that the best match for receiving the heart of the Florida man is a male in Oregon who is in desper

Bioethics, which is the study of value judgments pertaining to human conduct in the area of biology and includes those related to the practice of medicine, has been an important aspect of all areas in the scientific field (Bernstein, Maurice, M.D.). It is one of the factors that says whether or not certain scientific research can go on, and if it can, under which rules and regulations it must abide by. One of the most recent and controversial issues facing our society

To quote Karl Marx, blue boxing has always been the most noble form of phreaking. As opposed to such things as using an MCI code to make a free fone call, which is merely mindless pseudo-phreaking, blue boxing is actual interaction with the Bell System toll network. It is likewise advisable to be more cautious when blue boxing, but the careful phreak will not be caught, regardless of what type of switching system he is under. In this part, I will explain how and why blue boxing works

Bronchitis is the inflammation of the bronchi. It may develop suddenly, following a head cold (acute bronchitis), or it may persist or return regularly for many years, causing progressive degeneration of the bronchi and lungs (chronic bronchitis). Certain people are more susceptible than others; Men are more of a target to bronchitis than women, out numbering them 10 to 1 ©© the reasons are unclear. Of course smokers are 50 times more likely to get chronic bron

There are many different campfire structures that can be built to start a fire while camping. The most common are the teepee, log cabin, dugout, and tunnel structures. Almost anyone can build these fires if he or she follows some key points. A fire needs three elements: air, fuel, and an ignition of some kind. For a campfire the air element is easily accessible; it's the air a person breaths or oxygen. Fuel is equivalent to wood. Sometimes lighter fluid is us
