Is talc dangerous for babies? (archived) What is talc? Talc (hydrous magnesium silicate) is a soft greenish grey mineral found throughout the world. Itвs crushed, dried and milled to create talcum powder. In its raw form, talc is often contaminated with asbestos (a known carcinogen) and crystalline silica. In theory, contaminants are removed during the purification process but in reality some of these dangerous substances remain. Talc particles have the potential to enter and lodge themselves in the body -- reports focus on lungs and ovaries -- and cause tumours, lesions and other damage. Another safety issue relates to accidental inhalation of the powder: itвs said to dry out the lining of the lungs and can obstruct small airways, resulting in respiratory distress or even death.
Symptoms of emphysema vary from mild to severe and include shortness of breath (dyspnea), cough, and difficulty breathing upon exertion (e. g. , exercise). Emphysema is a chronic (long lasting), progressive condition, which means the symptoms usually worsen over time. Because the onset of the disease is gradual, many cases are not diagnosed until irreversible damage has occurred. Episodes of worsening symptoms (called exacerbations) are common in patients who have emphysema. Exacerbations become more frequent in advanced disease. Cyanosis (bluish tint to the lips, fingertips, and skin; caused by low levels of oxygen [O2] in the blood) Patients who have emphysema often have chronic bronchitis as well. Chronic bronchitis results in a productive cough that is present for at least 3 months
For those considering a degree in Computer Science but need further convincing, the Complete University Guide lends its expertise. Here's P6 compelling reasons to study for a Computer Science degree: 1. The digital age needs computer scientists Like it or not you're living in it this is the Digital Age. Computer programmes have all but infiltrated every aspect of our lives. Computer scientists theorise, design, develop, and apply the software and hardware for the programmes we use day in day out sounds pretty important to us. 2. Computer science students have excellent graduate prospectsP Check out our Computer Science, look down the Graduate Prospects column and you'll notice that computer science students stand a pretty good chance of being professionally employed or in further study

MassachusettsБ Supreme Judicial Court Б the stateБs highest court Б will hear arguments today in, a case in which an anonymous atheist couple is of the phrase Бunder GodБ in recitations of the Pledge of Allegiance in public schools. The plaintiffs, represented by the American Humanist Association, are appealing a lower court ruling that went in favor of the school district. With the school year getting underway around the country, here are five facts about the Pledge of Allegiance and its legal history: The original version of the Pledge of Allegiance did not include the words Бunder God.

Wouldn't it be great to make nearly $111 million a year simply to play a game? Tiger Woods, along with many other professional athletes, certainly think so. But do these athletes really deserve all that money? In my mind, absolutely not. Professional athletesбare making too much money in a society where salaries and wages are traditionally based on the value of one's work. In today's society, one should be paid according to the jobБs economic importance and their value to society. Teaching is one of the most economically important occupations because our future economy relies on the education of its youth, yet teachers are paid astronomically less than the average professional athlete is. In fact, each basket Kobe Bryant scores earns him equivalent to the average classroom teacherБs
Asked by: Liza Dennis, Brighton Solar eclipses are not actually rarer than lunar eclipses in fact, they occur in about equal numbers, usually about two of each per year. For example, between 2000BC to 3000AD there will be 11,898 solar eclipses and 12,064 lunar eclipses. However, at any one location on Earth, it is much less common to see a solar eclipse than a lunar one. And the reason for this is entirely due to geometry. A lunar eclipse, when the Moon moves through the shadow of the Earth, is visible from wherever the Moon is above the horizon, which is over half of the Earth. However, when the Moon appears to move in front of the Sun during a solar eclipse, the shadow cast by the Moon is much smaller than Earth. Its only about 480km (300 miles) wide when cast onto the Earths surface.
Reading and hearing about Greek mythology is one thing but why are modern people still made to study them? The answer to that is very simple: to learn. People still study the ancient Greeks and their myths much in the same reason they study other cultures and that is so they can learn from it. After all, when you study a culture as progressive as that of the ancient Greeks, you really canБt help but learn lessons. These myths, for their part, show modern people a glimpse of how they thought in the past, what they considered important, how their morals worked, etc. Another reason to study those Greek myths is because they have contributed a lot to classic and modern literature in the form of symbols. The ancient Greeks have influenced us in more ways than we can imagine. They have given us
Physical affection (e. g. , hugging and kissing) is an important aspect of romantic relationships. Displays of physical affection are associated with relationship satisfaction, and in turn greater relationship satisfaction is associated with greater sexual satisfaction. Therefore, physical affection plays a large role in the emotional and sexual benefits derived from a romantic pairing. In addition, research has shown than a person s satisfaction with the physical affection in their relationship is a strong predictor of love, liking, and overall satisfaction. Despite this connection, the ways in which we can express physical affection vary, and as such, more research is needed. Researchers surveyed 295 college students to examine the link between physical affection and relationship
