ASBESTOS |
|
Asbestos (a misapplication of Latin: asbestos "quicklime" from Greek ἄσβεστος: a-, "not"; sbestos, "extinguishable") describes any of a group of fibrous metamorphic minerals of the hydrous magnesium silicate variety. The name is derived for its historical use in lamp wicks; the resistance of asbestos to fire has long been exploited for a variety of purposes. It was used in fabrics such as Egyptian burial cloths and Charlemagne's tablecloth, which, according to legend, he threw in a fire to clean. Asbestos occurs naturally in many forms (see below); it is mined from metamorphic deposits.

BICYCLE HELMETS |
|
A bicycle helmet is designed to provide head protection for cyclists. Helmets are most suitable for preventing injury in straight falls, and for reducing friction related damage to the head. Modern bicycle helmets were first developed in the 1970s.

BIRTH INJURY |
|
Occasionally during the birth process, the baby may suffer a physical injury that is simply the result of being born. This is sometimes called birth trauma or birth injury. 1 in 200 babies is born with some form of birth injury, and many of these cases may have been caused by medical negligence.

CLOTHING / GARMENT / APPAREL |
|
Clothing is defined, in its broadest sense, as coverings for the torso and limbs as well as coverings for the hands (gloves), feet (socks, shoes, sandals, boots) and head (hats, caps). Humans nearly universally wear clothing, which is also known as dress, garments, attire, or apparel. People wear clothing for functional as well as for social reasons. Clothing protects the vulnerable nude human body from the extremes of weather and other features of our environment. But every article of clothing also carries a cultural and social meaning.

CRISIS COMMUNICATIONS |
|
Crisis communications is the art and science of working with the public through the print, broadast, cable and Internet media when an event, which could have negative, devastating impact to a governmental, corporate or non-profit organization, suddenly starts to gather hurricane strength. It is the most creative and exhausting counseling that a public relations and public affairs professional would be asked to perform as he turns a negative into a positive.

DEMOLITION |
|
Demolition is the opposite of construction: the tearing-down of buildings and other structures. It is contrasted with deconstruction, which is the taking down of buildings while carefully preserving valuable elements for re-use.
|
DROWNING |
|
Drowning is death caused by the filling of the lungs by a liquid, usually water, rendering breathing ineffective and leading to death due to asphyxia. Near drowning is initial survival of a drowning event, and can lead to serious secondary complications including death later on; cases of near drowning therefore also require attention by medical professionals. Secondary drowning is death due to chemical and biological changes in the lungs after a near drowning incident or exposure to chemicals. In many countries, drowning is one of the leading causes of death for children under 14 years old.

EYE DISEASE |
|
There are many diseases and disorders that may affect the eyes.
As the eye ages certain changes occur that can be attributed solely to the aging process. Most of these anatomic and physiologic processes follow a gradual decline.
|
LASIK |
|
LASIK, an acronym for Laser-assisted In Situ Keratomileusis, is a form of refractive laser eye surgery procedure performed by ophthalmologists intended for correcting vision. The procedure is usually a preferred alternative to photorefractive keratectomy, PRK, as it requires less time for full recovery, and the patient experiences less pain overall.
|
MOTORCYCLE HELMETS |
|
A motorcycle helmet is a type of protective headgear used by motorcycle riders. The primary goal of a motorcycle helmet is to protect the rider's head during impact, although many helmets provide additional conveniences, such as face shields, ear protection, intercom etc.

OPHTHALMOLOGY |
|
Ophthalmology is the branch of medicine which deals with the diseases of the eye and their treatment. The word ophthalmology comes from the Greek roots ophthalmos meaning eye and logos meaning word; ophthalmology literally means "the science of eyes." As a discipline it applies to animal eyes also, since the differences from human practice are surprisingly minor and are related mainly to differences in anatomy or prevalence, not differences in disease processes. By convention the term ophthalmologist is more restricted and implies a medically trained specialist. Since ophthalmologists perform operations on eyes, they are generally categorized as surgeons.
|
PEST CONTROL |
|
Pest control refers to the regulation or management of another species defined as a pest, usually because it is believed to be detrimental to a person's health, the ecology or the economy.
|
POLYMERS |
|
Polymer is a generic term used to describe a very long molecule consisting of structural units and repeating units connected by covalent chemical bonds. The term is derived from the Greek words: polys meaning many, and meros meaning parts [1]. The key feature that distinguishes polymers from other molecules is the repetition of many identical, similar, or complementary molecular subunits in these chains. These subunits, the monomers, are small molecules of low to moderate molecular weight, and are linked to each other during a chemical reaction called polymerization.

TIRES |
|
A tire (U.S. spelling) or tyre (UK spelling) is device covering the circumference of a wheel. It is an essential part of most ground vehicles and is used to dampen the oscillations caused by irregularities in the road surface, to protect the wheel from wear and tear as well as to provide a high-friction bond between the car and the road to improve acceleration and handling. Today most tires, especially those fitted to motor vehicles, are manufactured from synthetic rubber, however other materials such as steel may be used.
