The warning bells rang as Chad and Byron raced up the stairs. But at the top, Chad began gasping as his chest tightened. He stopped and felt inside his pocket.
Byron stopped, too. “Bad asthma attack?”
Chad wheezed and nodded, then pointed down the hall.
“We won’t be late. Got your inhaler yet?”
Chad pulled out a small plastic tube, shook it, and inhaled from it. He inhaled again and took several gulps of air. “I can breathe again. Let’s get going,” Chad said.
But before long, Chad was wheezing and coughing badly.
When the two friends reached the nurse’s office, Ms. Jassen hurried to Chad’s side. “What’s wrong?” she …
Sun Microsystems’ recently announced Ultra Enterprise 450 Work Group server is a stiff competitor for Compaq’s ProLiant servers. The Enterprise 450 levels the cost-of-ownership issue against Windows NT/Intel (Wintel) servers, offers better performance, supports PC-client environments, and offers the resiliency of Solaris and scalability across Sun’s Enterprise server product line (which supports up to 64 processors in a symmetric multiprocessor/server configuration). Compaq’s ProLiant 7000 (see article, next page) is strategically positioned against the 450, but Sun’s 450 announcement is a bold strike against Wintel.
The Enterprise 450 is a robust midrange server. It supports up to four UltraSparc II processors, which use Sun’s UPA system bus; it has a …
Mosquitoes are pesky little creatures. They bite–and you itch like crazy–but they also can carry much menace.
It all begins in the water.
Female mosquitoes lay their eggs in water. And some species don’t need much water: an old tire, a discarded cup from someone’s fast food lunch, a birdbath, a hole in a tree. Others hatch in still lakes or sewage ponds.
The larvae grow to be one-tenth to one-fourth-inch long, float to the top of the water, and are called “wrigglers.” They breathe air through a snorkel-like device (called a siphon) that they poke out of the water. They are filter feeders, sifting out organic debris …
To his teachers, 16-year-old Jason is the student most likely to fall asleep in class. After all, his school day is followed by a grueling basketball practice and three hours behind a fast-food counter. Then there’s homework, late-night phone chats with his girlfriend, and catching up on MTV. When Jason’s head finally hits the pillow, his mind is still racing with thoughts about everything from tomorrow’s history test to his latest outbreak of zits. Then, just when it seems like he’s finally settled into a cozy sleep, his alarm clock rousts him out of bed to start another day.
Jason is suffering from insomnia, a sleep disorder that …
Jessica would never forget the night she awoke in the middle of an earthquake. All she could think of was getting out of the house. Later, she huddled with her family and looked at the ruins of their home. “What are we going to do?” she whispered.
Eric slammed his bedroom door. He didn’t want to talk to his father OR his mother. “I felt angry about the divorce,” he said later, “but scared, too. I wasn’t sure what would happen to me.”
Marcie used to stay with her grandmother after school. Sometimes she brought a friend, and they listened to her wonderful stories. “Whenever I had a problem, …
Floods are devasting. People whose lives have been devastated by floods have suffered loss of homes, cars, pets, and even loved ones.
Since floods are nature’s most frequent natural disaster, maybe you have even survived a flood. You probably recall this year’s raging floods in California or the flooding in the Midwest in the summer of 1993, which many called the “flood of the century.” Even though major floods are reported in the national news, many small yet serious floods occur that are are not nationally reported. That’s why it’s important for your to know what to do in case a flood threatens you, your family, and …
Sharon awoke in the morning with a throbbing headache she couldn’t shake. Later that day she went to the doctor complaining of an achy tiredness and burning throat. Dr. Conroy popped a thermometer in Sharon’s mouth. “Have you been camping or in the woods lately?” she asked.
“Yes,” Sharon said. “We went camping over the weekend. Why?”
“Well, you definitely have a fever, and if that rash on your arm was caused by a tick, you may have Lyme disease. We’ll need to take a blood test.”
The Lowdown on Lyme
Lyme disease is a bacterial infection spread primarily through the infected bite of the black-legged tick (the so-called deer …
IF you’re looking forward to the balmy days of summer so you can get a healthy tan, you’d better think twice. Due to the rising rates of melanoma (the most deadly form of skin cancer) and other health problems caused by the sun’s rays, there’s no such thing as a “healthy” tan. How can something that makes you look great be so deadly?
Blame Those Ultraviolet Rays
The sun emits two types of ultraviolet (UV) radiation: UV-A and UV-B. According to the National Academy of Sciences, UV-A probably causes as much as 95 percent of the melanoma-inducing effect of sunlight. UV-A and UV-B both play major roles in causing less …
Whether you know it or not. Antioxidants are vitamins that are present in foods you eat every day–especially fruits, vegetables, nuts, and vegetable oils. Antioxidant vitamins are an important part of the body’s cell protection system. The antioxidants we have the most information on are vitamin C, vitamin E, and beta carotene, a form of vitamin A.
These antioxidant vitamins are at the center of one of today’s biggest health debates. Everyone agrees that they’re needed for good health. The debate is about whether consuming large amounts of these vitamins can help prevent cancer, heart disease, and other serious diseases.
What’s an Antioxidant?
Why are these vitamins referred …
Baseball is still America’s favorite pastime. Many people participate in the sport on many different levels. Most people, however, don’t think of it as an aerobic event. But baseball does focus on explosive power for hitting and short sprint running and provides a score of fitness benefits. Getting in shape for the game is extremely important.
“One of the key ingredients in training is building core strength–abdominal muscles, low back, and oblique muscles,” says Mark Cibrario, strength and conditioning coach at Glenbrook North High School in Northbrook, Illinois.
As a trainer for high school athletes in a variety of sports, Cibrario’s personal favorite is baseball. …
