  • A dog or cat will help children’s self esteem and social development – pets are accepting and give positive reinforcement to children. Having a pet will benefit your child’s development as it promotes learning how to be responsible. They will listen to all your stories without fail – even if your human friends get tired from time to time of what you have to say, your pet will always think you “look great”, will never argue with you, and will never tell you they are too tired to talk. This is one of the greatest benefits of pets that people don’t recognize!   Pets will make you laugh, the best stress reliever in the world – your new family pet will provide many hours of amusement for your family as you “explore” your world together. What a wonderful benefit of having a pet in your home!   Another benefit of pet ownership is they help older people feel less isolated – They lessen loss for older people who are on their own and help to keep them involved in caring for another being.   
  • Pets can keep you company while you garden - This may be a stretch, but there is nothing cuter than a cat peeking out from behind the petals of your flower garden or a dog helping you “turn the earth”. Some may not consider digging a benefit of having a pet, but if properly trained it shouldn’t be a problem and your dog can actually help you tote your gardening tools around the yard and your cat will appreciate the catnip in your herb garden.

  • Psychological behaviorism is a research program within psychology.
  • Analytical or logical behaviorism is a theory within philosophy about the meaning or semantics of mental terms or concepts
  • says that the very idea of a mental state or condition is the idea of a behavioral disposition or family of behavioral tendencies.
  • Psychology is the science of behavior. Psychology is not the science of mind. Behavior can be described and explained without making reference to mental events or to internal psychological processes. The sources of behavior are external (in the environment), not internal (in the mind). In the course of theory development in psychology, if, somehow, mental terms or concepts are deployed in describing or explaining behavior, then either (a) these terms or concepts should be eliminated and replaced by behavioral terms or (b) they can and should be translated or paraphrased into behavioral concepts.

Blue Sky - Why is the Sky Blue? - 0 views

  • end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy. LIGHT IN THE AIR Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors. Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the co

  • THE BLACK SKY AND WHITE SUN On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. In space, there is no atmosphere to scatter the sun's light. On Earth, some of the shorter wavelength light (the blues and violets) are removed from the direct rays of the sun by scattering. The remaining colors together appear yellow. Also, out in space, the sky looks dark and black, instead of blue. This is because there is no atmosphere. There is no scattered light to reach your eyes. WHY IS THE SUNSET RED? As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less
  • The sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.
  • RE ABOUT:THE ATMOSPHERE WHAT IS THE ATMOSPHERE? The atmosphere is the mixture of gases and other materials that surround the Earth in a thin, mostly transparent shell. It is held in place by the Earth's gravity. The main components are nitrogen (78.09%), oxygen (20.95%), argon (0.93%), and carbon dioxide (0.03%). The atmosphere also contains small amounts, or traces, of water (in local concentrations ranging from 0% to 4%), solid particles, neon, helium, methane, krypton, hydrogen, xenon and ozone. The study of the atmosphere is called meteorology. Life on Earth would not be possible without the atmosphere.
  • d increases with increasing altitude. The increase is caused by the absorption of UV radiation by the oxygen and ozone. · The temperature increase with altitude results in a layering effect. It creates a global "inversion layer", and reduces vertical convection. Mesosphere - Extends out to about 100 km (65 miles) · Temperature decreases rapidly with increasing altitude. Thermosphere - Extends out to about 400 km ( 250 miles)
  • hes the Earth, 30% is reflected back into space by clouds and the Earth's surface. The atmosphere absorbs 19%. Only 51% is absorbed by the Earth's surface. We are not normally aware of it but air does have weight. The column of air above us exerts pressure on us. This pressure at sea level is defined as one atmosphere. Other equivalent measurements you may hear used are 1,013 millibars, 760 mm Hg (mercury), 29.92 inches of Hg, or 14.7 pounds/square inch (psi). Atmospheric pressure decreases rapidly with height. Pressure drops by a factor of 10 for every 16 km (10 miles) increase in altitude. This means that the pressure is 1 atmosphere at sea level, but 0.1 atmosphere at 16 km and only 0.01 atmosphere at 32 km. The density of the lower atmosphere is about 1 kg/cubic meter (1 oz./cubic foot). There are approximately 300 billion billion (3 x 10**20, or a 3 followed by 20 zeros) molecules per cubic inch (16.4 cubic ce

The density of air also decreases rapidly with altitude. At 3 km (2 miles) air density has decreased by 30%. People who normally live closer to sea level experience temporary breathing difficulties when traveling to these altitudes. The highest permanent human settlements are at about 4 km (3 miles). LAYERS OF THE ATMOSPHERE The atmosphere is divided into layers based on temperature, composition and electrical properties. These layers are approximate and the boundaries vary, depending on the seasons and latitude. (The boundaries also depend on which "authority" is defining them.) LAYERS BASED ON COMPOSITION Homosphere

Basketball Tip, Basketball Tips, Basketball Shooting Tips, Free Basketball Tips - 0 views

  • One of the keys to getting the most out of your training program is to work outside of your comfort zone.
  • I can't argue that you're doing something to stay in shape and work on your game. But you're not really pushing yourself, and you shouldn't really expect those types of workouts to pay huge dividends.
  • Change your approach. Push yourself harder than you normally do, and you'll start to see results. Instead of shooting 30 or 40 random, lazy jump shots, create a plan for yourself. Shoot from 4 or 5 spots on the floor until you've made 30 or 40 shots from each spot (or some number that you set as a goal for yourself). Get in the triple-threat position, head-fake, take a quick dribble to one side or the other, get good lift on your shot (really getting off the ground), and concentrate on your follow-through. Push yourself to move quicker than you normally do, and to jump higher than you normally do.

  • Or when you go to the track, create a plan to really work on your stamina and quickness. Run 2 laps at a good pace to warm up. Then do some interval training where you sprint at top speed for 40 or 50 yards, then walk for 30 or 45 seconds to get your wind back. When you first start doing interval training, you'll probably only be able to do 4 or 5 repetitions, but you'll get in better shape over time and the numbers will increase. As you get into better shape, you'll work your way up to longer distances, shorter breaks in between sprints, and more repetitions. Follow-up your sprints with 4 or 5 hard minutes of jumping rope. Mix in some longer distance training during the week and you're on your way to really improving your stamina and quickness.

Aircraft - Wikipedia, the free encyclopedia - 0 views

  • An aircraft is a vehicle which is able to fly through the Earth's atmosphere or through any other atmosphere. Rocket vehicles are not aircraft if they are not supported by the surrounding air. All the human activity which surrounds aircraft is called aviation.
  • Heavier-than-air aircraft must find some way to push air or gas downwards, so that a reaction occurs (by Newton's laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term aerodyne. There are two ways to produce dynamic upthrust: aerodynamic lift, and powered lift in the form of engine thrust. Aerodynamic lift is the most common, with aeroplanes being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called rotary wings. A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, the wing must move forwards through the air; this movement of air over the aerofoil shape deflects air downward to create an equal and opposite upward force, called lift, according to Newton's third law of motion. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed or rotary. With powered lift, the aircraft directs its engine thrust vertically downwards. The initialism VTOL (vertical take off and landing) is applied to aircraft that can take off and land vertically. Most are rotorcraft. Others, such as the Hawker Siddeley Harrier, take off and land vertically using powered lift and transfer to aerodynamic lift in steady flight. Similarly, STOL stands for short take off and landing. Some VTOL aircraft often operate in a short take off/vertical landing regime known as STOVL. A pure rocket is not usually regarded as an aerodyne, because it does not depend on the air for its lift (and can even fly into space), however many aerodynamic lift vehicles have been powered or assisted by rocket motors. Rocket-powered missiles which obtain aerodynamic lift at very high speed due to airflow over their bodies, are a marginal case.
  • The forerunner of the aeroplane is the kite

Includes the important class of delta wings. Location of the horizontal stabiliser, if any. Dihedral angle - positive, zero or negative (anhedral). A variable geometry aircraft can change its wing configuration during flight. A flying wing has no fuselage, though it may have small blisters or pods. The opposite of this is a lifting body which has no wings, though it may have small stabilising and control surfaces.

Chiroptera - 0 views

  • One unique feature of bats is their modified forelimbs, which support a wing membrane (patagium). The basic elements of the mammalian limb are present in bats, although the relative sizes of most bones and muscles differ from those of nonflying mammals. The most elongated parts of the limb are those of the hand (metacarpal bones) and fingers (phalanges). The primary functions of these bones in bats is to provide support for the patagium and control its movements.
  • Numerous blood vessels and nerves are present throughout the wing membrane. Bats also have five unique muscles present in the patagium, and use additional muscles in the chest and back to move the wings up and down.
  • The most obvious difference between bird wings and those of bats is that bird wings are made of feathers, not a skin membrane. Birds have an elongated arm, but do not have elongated fingers like bats. Additionally, the muscles used in both the upstroke and downstroke are found in the chest of birds, while the upstroke muscles are on the back in bats (Fenton, 1983).
  • ...7 more annotations...
  • The orientation of the hindlimb is also unique to bats. The hip joint is rotated 90° so that the legs project sideways and the knee faces almost backwards. Due in part to the rotation of the hindlimb, the walking motion of bats differs from other tetrapods, often appearing awkward. The hindlimb is designed to support the patagium in flight and allow the bat to roost hanging from its hindlimbs. Most bats have a tendon system in the toes that locks the claws in place so the bat can hang upside down even when asleep.
  • The body of a bat is ventrally compressed with a short neck region. The bones tend to be slender and light-weight. The majority of the body weight is concentrated in the chest region due to the large flight muscles.
  • The overall shape of the head varies more in bats than within most other groups of mammals. Some bats have very elongated muzzles while others have broad, short faces. There is a correlation between the shape of the head and the type of food eaten. For example, most nectar feeders have long, narrow muzzles that are good for reaching into flowers, while many fruit eaters have short, broad faces good for biting rounded fruits (Hill and Smith, 1984).
  • The ears range from small and round to large and pointed, and often have a cartilaginous fold (tragus) present at the notch of the ear. There is additional variation in the nasal and lip regions of bats. Some bats have complex noseleafs, folds, or wrinkles on their muzzles.
  • A major misconception about bats is that they are blind. This idea originated from the fact that bats are able to successfully maneuver in the dark and often have small eyes. While some bats do have very small eyes (most Microchiroptera) many have large and complex eyes (Megachiroptera).
  • Bats usually have black or brown fur, although the fur can also be gray, white, red, or orange. In some species there are stripes on the face or down the back, or patches of white on the face or above the shoulder. The length of the fur also varies among species from short and dense to long and fluffy. The wing membrane is usually dark in color, although it may have white on the tips or be a lighter color around the bones in the membrane. A few bats have white or pale yellow wings. There are also little hairs on the membrane itself. These hairs can be the color of the wing or the same color as the body.
  • The bat monophyly hypothesis states the Megachiroptera and Microchiroptera are each others closest relatives in an evolutionary sense (i.e., they form a clade).

The dope on steroids: Why some athletes take the risk : UMNews : University of Minnesota - 0 views

  • The stakes in Athens are fierce. The difference between an Olympic gold or silver medal could be a one hundredth of a second on the track or in the pool; an inch on the pole vault or shot put.
  • The athletes who make the Olympic cut are blessed with the right combination of physical and psychological traits, including an intense competitive drive and an unrelenting determination to be the best. This is the stuff of champions.
  • Steroids are not just for elite athletes--they can be used by anyone who wants to change his or her body image. The Centers for Disease Control's Youth Risk Behavior Surveillance report shows more than a million youth taking steroids, and the numbers have been rising every year.
  • ...13 more annotations...
  • Unfortunately, sometimes so are steroids. For decades, athletes have used anabolic (meaning muscle-building) steroids and other performance-enhancing drugs to build strength and endurance. And those drugs are getting more and more sophisticated in an effort to evade detection. Doping, as the practice is called, is illegal and, by most people's standards, unethical. Athletes who have been caught using these drugs have been stripped of their Olympic medals and world records and banned from their sports, sometimes for years, and on occasions for a lifetime.
  • "There are rights and wrongs in life, and if it's against the rules, it's cheating to do it," says Wiese-Bjornstal. "I love sports, but some athletes treat elite sports as if they are life itself, more important than their health, their loved ones, and even their lives."
  • In addition, steroids mess with your body. Potential side effects include high blood pressure, strokes, nausea, sleep problems, increased aggressiveness, and severe mood swings. In men, steroids can reduce sperm count and cause impotence, breast growth, and shrunken testicles. In women, side effects can include reduced breast size, increased body and facial hair, a deepened voice, and menstrual problems.
  • With the risks and consequences of steroid use so high, why do some athletes continue to dope?
  • "The major underlying factor [with steroids use] is that winning at all costs is the most important thing," says Diane Wiese-Bjornstal, associate professor in the School of Kinesiology.
  • She says that athletes that use steroids often have the mindset that "they are demonstrating that they are as highly committed to their sport as they can be and are doing whatever it takes to prove to themselves, their coaches, and to the world that they are true athletes who will do anything to win."

      Diane Wiese-Bjornstal's Comment
  • From a moral and ethical framework, Wiese-Bjornstal believes this is twisted thinking. "There are rights and wrongs in life, and if it's against the rules, it's cheating to do it," she says. "I love sports, but some athletes treat elite sports as if they are life itself, more important than their health, their loved ones, and even their lives."
    • anonymous
       
      Wiese-Bjornstal's Comment
  • She also says there is pressure to dope because of the belief that everyone else is doing it, and that if an athlete wants to compete at the highest level, she or he has to do it, too.
  • Nancy Cullen, a sports psychology consultant for the University, says the temptation to use steroids and other performance-enhancing drugs simply comes down to the rigors and pressure of elite competition and the desire to win. She cites an alarming poll taken in 1995 of 198 sprinters, swimmers, power lifters and others, most of whom were Olympians or aspiring Olympians. The poll asked if the athletes would take a banned performance-enhancing substance if they knew if would help them win and they wouldn't be caught--195 responded, yes.
  • Most athletes train for perfection," says Cullen. "The drive to achieve and win is so strong. If the difference between winning or losing is a hundredth of a second, and there is a drug that might give you the edge, the temptation can be great."
  • For some Olympic events, steroid scandals have cast a pall over the games, leaving viewers to wonder after each win, "Did he take drugs? Did she?"
  • Both Wiese-Bjornstal and Cullen agree that education, beginning with young athletes, is important in the fight against steroid use, as are drug testing and stiffer penalties for those who are caught. They also believe that coaches and parents play an important role in supporting the healthy ambitions of developing athletes.
  • "It's important to teach athletes to know what the consequences are and to learn other training practices that are legal and don't involve taking drugs," says Cullen. "Strive to win, strive for perfection, but do it within the rules of the game."

List of breakdance moves - Wikipedia, the free encyclopedia - 0 views

  • The Top Rock is a combination of steps done while standing up. This is the entry dance that Bboys and Bgirls use to start their set. These steps are done before you do a power set or before you go down to the floor. This is the breaker's chance to show how well he or she can rock the beat and/or make gestures to intimidate their opponent
  • The foundational footwork sequence. Although many variations exist that either add or subtract steps in the sequence, the 6-step is the most basic form of downrock.
  • A Power Move is any type of move in Bboying which requires spinning and/or rotating in a way that can be done so in multiple rounds. All Power Moves (or series of a type of Power Move) can be connected in combos to form a "Power Combo". Breakers that use mostly Power combos in there sets are commonly known as "Power Heads". Example: Flare-Air Flare-Elbow Air Flare-Air Flare-1990...etc Or-Air Flare 1.5-Babymill-Windmill-Swipe-Windmill-Halo-Headspin...etc The possible number of combinations are endless and only limited by stamina, strength and imagination. In 2002 The Guinness Book of World Records began tracking number of power move rotations for their world record standings. At that time Canadian Gregory Burbidge broke records for Air Flare, Headspins, and Elbow Airflares. American Lauren Jacob held the record for Chair Flares. American Laura Derrick held the record for Tappingmills. Nicole Jones (nationality unknown) held the record for Munch Airflares. In 2004 Guinness removed these titles from their records. At the time Gregory Burbidge was the only one who still held records from the original group.

Other kinds of music are instrumental music, opera, etc. Those kinds of music also affect you. The music that affects you the most is calm music like instrumental or fast music like rock or techno. Rock and techno make you speed up, and instrumental or calm music makes you slow down and feel more calm.

      oooooooooooooooooohhh i didnt know this its kind of off topic but i like it it does have music involved
  • Music can also slow down and equalize brain waves. A brain has 4 kinds of waves. It has beta waves, alpha waves, theta waves, and delta waves. When we do daily activities and experience emotions that’s when we use beta waves. Calmness is when we use alpha waves ,when your sleeping you use theta waves , and lastly when you are in deep sleep or in meditation that is when delta waves are used. When your brain waves are slow that is when you are very calm. Different types of music cause different waves. If you listen to calm music then the waves will drop to delta and theta. If you listen to fast or loud music your brain waves will most likely be alpha or beta.

Howstuffworks "How Performance-Enhancing Drugs Work" - 0 views

  • Every two years as the Olympic Games begin, we hear about athletes using or at least being tested for performance-enhancing drugs. Every time the Tour de France rolls around, there's talk of possible doping. Sometimes, competitors raise the question when one athlete does particularly well. Other times, tests catch athletes with drugs in their systems. The practice of using artificial substances or methods to enhance athletic performance is called doping. Doping has become such a great concern that the United States formed an Anti-Doping Agency.
  • Why Some Athletes Use DrugsAthletes face enormous pressure to excel in competition. They also know that winning can reap them more than a gold medal. A star athlete can earn a lot of money and a lot of fame, and athletes only have a short time to do their best work. Athletes know that training is the best path to victory, but they also get the message that some drugs and other practices can boost their efforts and give them a shortcut, even as they risk their health and their athletic careers.
  • As far back as ancient Greece, athletes have often been willing to take any preparation that would improve their performance. But it appears that drug use increased in the 1960s. One well-publicized incident happened at the Seoul Olympics in 1988 when sprinter Ben Johnson tested positive for anabolic steroids and was stripped of his gold medal. Athletes may also misuse drugs to relax, cope with stress or boost their own confidence. Athletes may have several reasons for using performance-enhancing drugs. An athlete may want to: Build mass and strength of muscles and/or bones Increase delivery of oxygen to exercising tissues Mask pain Stimulate the body Relax Reduce weight Hide use of other drugs

  • A steroid is a chemical substance derived from cholesterol.
  • he body has several major steroid hormones -- cortisol and testosterone in the male, estrogen and progesterone in the female. Catabolic steroids break down tissue, and anabolic steroids build up tissue. Anabolic steroids build muscle and bone mass primarily by stimulating the muscle and bone cells to make new protein.
  • Athletes use anabolic steroids because they increase muscle strength by encouraging new muscle growth. Anabolic steroids are similar in structure to the male sex hormone, testosterone, so they enhance male reproductive and secondary sex characteristics (testicle development, hair growth, thickening of the vocal cords). They allow the athlete to train harder and longer at any given period.
  • Anabolic steroids are mostly testosterone (male sex hormone) and its derivatives. Examples of anabolic steroids include: Testosterone Dihydrotestosterone Androstenedione (Andro) Dehydroepiandrosterone (DHEA) Clostebol Nandrolone
  • hese substances can be injected or taken as pills. Anabolic steroids have a number of possible and well-known side effects, including: Jaundice and liver damage because these substances are normally broken down in the liver Mood swings, depression and aggression because they act on various centers of the brain In males, the excessive concentrations interfere with normal sexual function and cause: Baldness Infertility Breast development
  • In females, the excessive concentrations cause male characteristics to develop and interfere with normal female functions. The drugs can: Stimulate hair growth on the face and body Suppress or interfere with menstrual cycle, possibly leading to infertility Thicken the vocal cords, which causes the voice to deepen, possibly permanently If pregnant, interfere with the developing fetus

  • ORIGIN OF THE CELEBRATION Section: Festival The start of the New Year has been celebrated in China for more than 3,000 years. New Year was a time when the farmers gave thanks for the harvest and prayed to the gods for a good harvest in the coming year. This was the one period in the busy farming year when there was time to have a celebration and when the family could get together, relax, and be merry. Chinese New Year begins with a New Moon. The Lunar Year is calculated from the time it takes for the Moon to travel around the Earth, while the Western (Gregorian) calendar is based on the time it takes for the Earth to circle the Sun. The orbits of the Moon bear no relation to the time it takes for the Earth to go around the Sun, which is why the Chinese Lunar New Year is celebrated on a different date each year. In China the New Year was renamed the Spring Festival, in 1911, when the Western calendar was officially accepted in China. However, it is still commonly known around the world as the Chinese New Year. Chinese years are named after one of twelve animals. These have been used in the same order to name the years since the sixth century A.D. Each animal is said to have its own personality and emotions, which are present in people born within its year. ~~~~~~~~By Sarah Moyse This article is copyrighted.

  • RELIGIONS AND RITUALS Section: Festival Although the New Year celebration is not mainly a religious one, many Chinese will visit a temple at this time of the year to make an offering to the Buddha or to the gods in the hope of making the New Year a good one. Ancestors and gods are honored with ceremonies in the home around a family altar decorated with flowers. Incense and candles are burned at the altar. At important family banquets the ancestors may be recognized as "spiritual guests" and first offered food that is afterward eaten with the meal. The Chinese have three main systems of ideas that are important to them: Confucianism, Daoism, and Buddhism. Although these systems are very different, many Chinese follow some or all of the rituals associated with them just to be safe. Confucius lived in the fifth century B.C. and spoke about the value of good behavior in private life and in government. He said that politeness, honesty, courage, and loyalty were what made good people. He believed in self-development through education and thought that people gain in wisdom as they grow older. It is part of the Confucian tradition to honor parents and ancestors.
  • Daoism comes from the teachings of Laozi, who lived at the same time as Confucius. His book, the Dao De Jing (The Way and Its Power), describes the way (dao means "way") to live at peace with nature so as not to upset natural balances. The Way involves balance between opposite forces. They are called yin and yang. While yin is dark and female, yang is the opposite, being light and male. When yin and yang are balanced, there is perfect harmony with nature. Unlike Confucianism and Daoism, which started in China, Buddhism came from India and is based on the teachings of the Buddha -- a holy man. Buddha taught that people need to let go of earthly desires and become fully aware of what they are doing in the present. Buddhists believe that after death each soul moves on to another body, which may be animal or human. What one is chosen for in the next life depends on how good or bad the person has been in this life. The Chinese also pray to other gods, holding the view that the more gods who can look after them the better. The important ones are the Kitchen God, who watches the family in the home, the Jade Emperor, who is the most important god in heaven, the God of Wealth, who determines how wealthy people are, and the Door Gods. ~~~~~~~~By Sarah Moyse This article is copyrighted.

  • HOLIDAY CELEBRATIONS On New Year's Eve, Chinese families have a special feast of seafood and dumplings. Dessert is always Nian Gao- a special New Year's Cake. Everyone stays up late to watch the midnight fireworks. On New Year's Day families go door to door to visit. They exchange gifts with their relatives and neighbors. It is thought to be bad luck to fight or argue at the start of a New Year. Everyone is warm and friendly toward each other. Fireworks light the night sky during a New Year celebration in Hong Kong. ~~~~~~~~By Kieran Walsh Kieran Walsh is a winter of children's nonfiction books, primarily on historical and social studies topics.

The Health Benefits of Owning a Cat: Pets Reduce Risk of Heart Attack, Stroke, and Othe... - 0 views

  • Cat ownership helps children to learn responsibility and develop a greater capacity for empathy at an early age. In addition, pets provide unconditional love and acceptance, which can help children through difficult times.
  • Cats also offer protection against certain physical conditions. If adopted before or shortly after a child is born, owning a cat reduces the risk of developing animal allergies, asthma, and possibly other illnesses as well. One study found that children living with pets were 13-18% less likely to miss school due to illness than children without pets. Researchers who measured the salivary immunologobulin levels of young pet owners found that their immune function was less likely to be in the sub-normal range than that of non-pet-owners.

      The Santa Monica Bay Restoration Project conducted a study to identify adverse health effects of untreated urban runoff by surveying over 13,000 swimmers at three bay beaches. The study established a positive association between an increased risk of explains health outcome measures at various distances from storm drains. For example, the study found a 1-in-14 chance of fever for swimmers in front of the drain versus a 1-in-22 chance at 400 or more yards away.

  • The three primaryactivities used in these programs include efforts to characterizestorm water runoff; BMPs aimed at reducing pollutants in stormwater runoff to the maximum extent practicable; and reportingprogram activities, monitoring results, and costs of implementingthe program. Some BMPs are structural-meaning that they aredesigned to trap and detain runoff until constituents settle orare filtered out.

  • Several officials in the cities we visited said that their annualcosts are likely to increase. A number of factors could affectthe costs. For example, a Baltimore City official explained thatthe anticipated, future program costs depend on several factors,including (1) requirements in watershed- management planscurrently being developed, (2) pollution-reduction goals the citywill be required to achieve, (3) requirements of the stateregulatory agency in future permits, and (4) requirements thecity may have to meet if TMDLs or numeric effluent limits areincorporated into NPDES storm water permits. Other city officialsalso expressed concern about the extent to which TMDLs couldaffect their future costs. These city officials are concernedthat when and if TMDLs are established, their future storm waterpermits may require that storm water runoff meet specific waterquality standards. For example, Los Angeles County's trash TMDLcould potentially drive the county's storm water management costsupward, and the county expects additional TMDLs to be imposed. Onthe other hand, Worcester officials estimated that their futurestorm water costs would be about the same as they were at thetime of our review-about $4.5 million per year.

The Wrong Way to Win - 0 views

  • The Wrong Way to Win › Introduction to The Wrong Way to Win › Why Do Athletes Use Performance-enhancing Drugs? › Masking Pain and Managing Weight and Stress › Detecting Drugs Why Do Athletes Use Performance-enhancing Drugs?
  • An athlete may want to: Build mass and strength of muscles and/or bones Increase delivery of oxygen to exercising tissues Mask pain Stimulate the body Hide use of other drugs
  • Many drugs are banned outright in Olympic competitions. However, some drugs, such as cortisone and local anesthetics, are merely restricted because they have legitimate clinical uses. Athletes may also misuse drugs to reduce weight, relax, cope with stress or boost their own confidence. Whatever the reason, doping has many unsafe if not deadly side effects.

  • Another method for improving oxygen concentration is blood doping -- infusing whole blood into an athlete. An athlete who infuses his own blood may cause infection or cardiovascular problems because of the increased blood volume (high blood pressure, blood clots, heart failure and stroke). An athlete who uses someone else's blood runs the risk of acquiring viral infections such as HIV/AIDS. These are huge risks for a result that can also be achieved by training at high altitudes.
  • In addition to taking drugs that build mass and strength, some athletes take drugs and engage in practices that increase the amount of oxygen in tissues. Endurance athletes, like cyclists or cross-country skiers, may use Erythropoietin (EPO). EPO can increase an athlete's oxygen supply by as much as seven to 10 percent. As mentioned earlier, EPO is extremely dangerous, if not deadly in some cases. The increased red cell density caused by EPO can thicken the blood. The thickened blood -- which is more like honey than water -- cannot flow through the blood vessels well. To pump the thickened blood, the heart must work harder. This increases the chances of heart attack and stroke.
  • Athletes looking to build mass may also abuse Human Growth Hormone (hGH). Excessive hGH levels increase muscle mass by stimulating protein synthesis, strengthen bones by stimulating bone growth and reduce body fat by stimulating the breakdown of fat cells. Use of hGH has become increasingly popular because it is difficult to detect. Side effects include overgrowth of hands, feet, and face (known as acromegaly), enlarged internal organs, especially heart, kidneys, tongue and liver and heart problems.
  • Athletes use anabolic steroids to increase muscle strength. Anabolic steroids, which can be injected or taken as pills, allow the athlete to train harder and longer at any given period. The possible and well-known side effects of anabolic steroid use include jaundice and liver damage, mood swings, depression and aggression. Men may also suffer from baldness, infertility and breast development. Females may grow excessive hair on the face and body and suffer from infertility. The substances Human Chorionic Gonadotropin (hCG), Luteinizing Hormone (LH) may also produce the same side effects.

Dog and Cat Owners Gain Health Benefits - BestFriendsPetCare.com - 0 views

  •  
    Good for body Some of the studies show that owning a pet can have very real physical benefits for their owners. These include: * Pet owners have lower blood pressure. It has long been known that the act of stroking a pet can reduce blood pressure. But a study at the State University of New York at Buffalo found that the beneficial effects continue even when the pet is not present. The study, which looked at a group of stockbrokers with hypertension, concluded that just owning a pet can help lower blood pressure -and keep it lower, even in stressful settings. * Pet owners have lower blood cholesterol levels. A study of more than 5,400 people conducted by Australia's Baker Medical Research Institute found that pet owners had not only lower blood pressure, but also lower levels of blood cholesterol and triglycerides in comparison to the non-pet owners, reducing the risk of heart disease. * Pet owners have a higher survival rate after serious illness. Two studies have found that heart attack patients who owned the pets were significantly more likely to be alive a year after they were discharged from the hospital than those who didn't. What's more, a study conducted at City Hospital in New York found that the presence of a pet affected survival rate even more than having a spouse or friends. Patients in hospitals or nursing homes who have regular visits from their pets have shown to be more receptive to treatment. The need to care for their pet gives them reason to recover and the will to live. * Pet owners have fewer doctors' visits. Studies conducted by Cambridge University in England and at the University of California at Los Angeles have found that pet ownership corresponds to overall improved health and fewer medical care visits. A study of Medicare patients also found that seniors who own dogs go to the doctor less than those who do not. Even the most highly-stressed older dog owners in the study had 21 % fewer physician's visits than non-dog ow

Cat School - 0 views

  •  
    All cats love to play, and playing is an important part of any kittens development. Playing is how cats learn the important lessons of attack and defense. They may look cute when attacking a ball or piece of metal foil, but they are actually learning or practicing the art of stalking, chasing and pouncing. Cats need to play all through their lives, so don't stop playing with him just because he reaches adulthood. A cat that is played with regularly is more likely to be happy, content and healthy and less likely to suffer from behavioural and weight problems. Just like humans, a cat who remains ative in mind and body can remain healthy and alert well into their old age.

  • Section: Festival The start of the New Year has been celebrated in China for more than 3,000 years. New Year was a time when the farmers gave thanks for the harvest and prayed to the gods for a good harvest in the coming year. This was the one period in the busy farming year when there was time to have a celebration and when the family could get together, relax, and be merry. Chinese New Year begins with a New Moon. The Lunar Year is calculated from the time it takes for the Moon to travel around the Earth, while the Western (Gregorian) calendar is based on the time it takes for the Earth to circle the Sun. The orbits of the Moon bear no relation to the time it takes for the Earth to go around the Sun, which is why the Chinese Lunar New Year is celebrated on a different date each year. In China the New Year was renamed the Spring Festival, in 1911, when the Western calendar was officially accepted in China. However, it is still commonly known around the world as the Chinese New Year. Chinese years are named after one of twelve animals. These have been used in the same order to name the years since the sixth century A.D. Each animal is said to have its own personality and emotions, which are present in people born within its year. ~~~~~~~~By Sarah Moyse This article is copyrighted.

  • Holidays are very important to the French. The French begin the year with a celebration of the Jour de l'An, which is New Year's Day. They greet each other by saying "Bonne Annee!" (Happy New Year). On January 6th there is la Fete des Rois (the Festival of the Three Kings), where people have a King's Cake. Whoever finds the special toy that has been baked into the cake gets to be king or queen for the day. In February, the French celebrate la Saint-Valentin or Valentine's Day by giving, valentines and chocolates. Also the French mark the start of Lent (a religious time when people fast) with Mardi Gras celebrations. On the 1st of April people play tricks on each other and say "Poisson d'avril!" which means "April fish!" People have little paper fishes that they cut out and try to stick on the backs of their friends that day. Easter is an important holiday in France. On the morning of Easter Sunday, most French people go to church. Afterwards, they carry home candles that have been blessed by priests. For Easter, which is called Le Pacques, omelettes, (an egg dish) are usually eaten for breakfast. People also give each other chocolate eggs and chocolate bunnies.

During the summer months, there is the Tour de France, which is a bicycle race. The 14th of July is France's Independence Day, called Bastille Day. There are parades and fireworks, and people decorate their houses and celebrate all day. Christmas is a favorite holiday in France for the young and old. On Christmas Eve, families often attend midnight mass. After church, they return home for a big dinner called le reveillon. Dinner often consists of such foods like soup, turkey, goose, and oysters. A popular dessert at Christmas time is buche de Noel, a cake filled with chocolate and rolled into the shape of a log. The cake represents the Yule log that burns in the fireplaces of the French people during Christmas.
