Gasoline /ˈɡæsəliːn/, also known as petrol /ˈpɛtrəl/ outside of North America, is a transparent, petroleum-derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives.

On average, a 42-gallon barrel of crude oil yields about 19 gallons of gasoline when processed in an oil refinery, though this can and does vary based on the crude oil source's assay.

The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Gasoline is produced in several grades of octane rating. Tetraethyllead and other lead compounds are no longer used in most areas to regulate and increase octane-rating, but many other additives are put into gasoline to improve its chemical stability, control corrosiveness and provide fuel system 'cleaning,' and determine performance characteristics under intended use. Sometimes, gasoline also contains ethanol as an alternative fuel, for economic or environmental reasons.

Gasoline is an album by indie rock group The Hard Lessons, released by No Fun Records on May 28, 2005 (see 2005 in music). It was received with generally favorable reviews.

A paw is the soft foot of a mammal, generally a quadruped, that has claws.

Common characteristics

The paw is characterised by thin, pigmented, keratinised, hairless epidermis covering subcutaneous, collagenous, and adipose tissue, which make up the pads. These pads act as a cushion for the load-bearing limbs of the animal. The paw consists of the large, heart-shaped metacarpal or palmar pad (forelimb) or metatarsal or plantar pad (rear limb), and generally four load-bearing digital pads, although there can be five or six toes in the case of domestic cats and bears (including giant panda). A carpal pad is also found on the forelimb which is used for additional traction when stopping or descending a slope in digitigrade species. Additional dewclaws can also be present.

The paw also includes a horn-like, beak shaped claw on each digit. Though usually hairless, certain animals do have fur on the soles of their paws. An example is the red panda, whose furry soles help insulate them in their snowy habitat.

SMS language or textese (also known as txt-speak, txtese, chatspeak, txt, txtspk, txtk, txto, texting language, txt lingo, SMSish, txtslang, txt talk) is a term for the abbreviations and slang commonly used with mobile phone text messaging, but sometimes used with other Internet-based communication such as email and instant messaging.

Three features of early mobile phone messaging encouraged users to use abbreviations: (a) Text entry was difficult, requiring multiple key presses on a small keypad to generate each letter; (b) Messages were limited to 160 characters, and (c) it made texting faster.

Once it became popular it took on a life of its own and was often used outside of its original context. At its peak, it was the cause of vigorous debate about its potentially detrimental effect on literacy, but with the advent of alphabetic keyboards on smartphones its use, and the controversies surrounding it, have receded.

History

SMS language is similar to that used by those sending telegraphs that charged by the word. It seeks to use the fewest number of letters to produce ultra-concise words and sentiments in dealing with space, time and cost constraints of text messaging. This follows from how early SMS permitted only 160 characters and some carriers charge messages by the number of characters sent.
