Blowout (tire)

A blowout is a rapid loss of inflation pressure of a pneumatic tire leading to an explosion. The primary cause for this is encountering an object that cuts or tears the structural components of the tire to the point where the structure is incapable of containing the pressurized air, with the escaping pressurized air adding to further tear through the tire structure.

It is also fairly common for tread separations to be termed “blowouts” - even those where the inflation pressure is not compromised. Because of this confusion, the term is rarely used by experts in tire failures, where the term "impact damage" is more frequently used.

Tire blowouts have been a concern since the dawn of the motoring age. First generation automotive tires suffered from frequent problems until technology developed.

Blowout (geomorphology)

Blowouts are sandy depressions in a sand dune ecosystem (psammosere) caused by the removal of sediments by wind.

Commonly found in coastal settings and arid margins, blowouts tend to form when wind erodes into patches of bare sand on stabilized vegetative dunes. Generally, blowouts don’t form on actively flowing dunes due to the fact that they need to be bound by some extent, such as plant roots. These depressions usually start on the higher parts of the stabilized dunes on the account that desiccation and disturbances are more considerable which allows for greater surface drag and sediment entrainment when sand is bare. Most of the time, exposures become quickly re-vegetative before they could become blowouts and expand; however, when the opportunities are given, wind erosion can lower the exposure surface and create a tunneling affect, which increases the wind speed. The depression may continue until it hits a non-erodible substrate or morphology limits it. The eroded substances climbs the steep slopes of the depression and become deposited on the downwind side of the blowout which can form a dune that covers vegetation and lead to a larger area of depression; a process that helps create parabolic dunes.

Hair straightening

Hair straightening is a hair styling technique used since the 1890s involving the flattening and straightening of hair in order to give it a smooth, streamlined, and 'sleek' appearance. It became very popular during the 1950s among black males and females of all races. It is accomplished using a hair iron or hot comb, chemical relaxers, Japanese hair straightening,Brazilian hair straightening, or roller set/blowdryer styling. In addition, some shampoos, conditioners, and hair gels can help to make hair temporarily straight.

The process is often called "rebonding" in some countries from Southeast Asia (e.g. Singapore, Malaysia and Philippines). The term "rebonding" was first used by REDS Hairdressing from Singapore in the late 1980s, which slowly spread to the rest of the region. If done often, flat irons and chemicals can be damaging to hair. Excessive straightening often results in split ends. However, heat protectant sprays can decrease the damage.
