Music

Music is an art form that involves organized sounds and quiet. It is articulated in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture).Music may also absorb generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, traditional or religious purposes. The definition of what constitutes music varies according to culture and social context, with assorted interpretations of the term being established under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.

The history of music predates the written word and is tied to the enlargement of each unique human culture. The development of music among humans occurred against the backdrop of natural sounds such as birdsong and the sounds other animals use to communicate. primeval music, once more commonly called primitive music, is the name given to all music created in preliterate cultures (prehistory), beginning somewhere in very late geological history.

Cooking barbecued food properly

Always make sure you cook chicken, pork, burgers, sausages and kebabs until they're piping hot all the way through, none of the meat is pink and any juices run clear.

If you're barbecuing for lots of people, you could cook meat indoors and finish it off on the barbecue for added flavour.

Remember, when you reheat food on the barbecue, always make sure it's piping hot all the way through before serving.

Also:

* Wait until the charcoal is glowing red, with a powdery grey surface, before you start to cook.
* Make sure frozen food is properly thawed before you cook it.
* Turn the food regularly, and move it around the barbecue, to cook it evenly.
* Check that the centre of the food is piping hot.
* Don't assume that if meat is charred on the outside that it will be cooked properly on the inside.

Computer Energy Savings

Every time we leave on computers when not in use, we are wasting electricity. Following are a few simple tips to consider:

* Turn off all desktop computers and peripheral devices, including monitors and storage media devices, at night and during any prolonged absence such as weekends or vacation time. Turning off the equipment at night can cut the annual energy costs from 100 to 400 kWh per computer. Contrary to popular belief, turning equipment on and off does not shorten the life span of computers or related equipment.

* Computer manufacturers provide Energy Star power-management features that allow you to program your computer to go into "sleep" mode after a certain time interval. Information Services recommends that you set your power management to turn off your monitor after 10 minutes and your hard disks after 20 minutes. See Power Management for PC and Mac instructions for setting power management.

* Limit screen-saver use. A screen saver does not save energy. In fact, more often than not, a screen saver not only will draw power for the monitor, but also will keep the CPU from shutting down. You can set your computer to go from screen-saver to sleep mode.

* Purchase flat-screen monitors. They use significantly less energy and are not as hard on the eyes.

Food allergy and intolerance

Food allergy and food intolerance are both types of food sensitivity. When someone has a food allergy, their immune system reacts to a particular food as if it isn't safe. If someone has a severe food allergy, this can cause a life-threatening reaction.

Food intolerance doesn't involve the immune system and is generally not life-threatening. But if someone eats a food they are intolerant to, this could make them feel ill or affect their long-term health.

If you think you have a food allergy or intolerance, then it's important to get a proper diagnosis. Don't cut food groups out of your diet without medical advice, because you could miss out on important nutrients.

If you want to know when a food has been withdrawn or recalled because the allergy labelling is missing or incorrect or if there is any other food allergy risk, check out the Agency's Allergy Alerts page on food.gov.uk. You can also sign up for email or text alerts.

Bone Health

Bones play many roles in the body. They provide structure, protect organs, anchor muscles, and store calcium. Adequate calcium consumption and weight bearing physical activity build strong bones, optimizes bone mass, and may reduce the risk of osteoporosis later in life.

Peak Bone Mass

Peak bone mass refers to the genetic potential for bone density. By the age of 20, the average woman has acquired most of her skeletal mass. A large decline in bone mass occurs in older adults, increasing the risk of osteoporosis. For women this occurs around the time of menopause.

It is important for young girls to reach their peak bone mass in order to maintain bone health throughout life. A person with high bone mass as a young adult will be more likely to have a higher bone mass later in life. Inadequate calcium consumption and physical activity early on could result in a failure to achieve peak bone mass in adulthood.

Osteoporosis

Osteoporosis or "porous bone" is a disease of the skeletal system characterized by low bone mass and deterioration of bone tissue. Osteoporosis leads to an increase risk of bone fractures typically in the wrist, hip, and spine.
