Weight loss

Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue and/or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional weight loss is commonly referred to as slimming.

Unintentional

Characteristics

Unintentional weight loss may result from loss of body fats, loss of body fluids, muscle atrophy, or even a combination of these. It is generally regarded as a medical problem when at least 10% of a person's body weight has been lost in six months or 5% in the last month. Another criterion used for assessing weight that is too low is the body mass index (BMI). However, even lesser amounts of weight loss can be a cause for serious concern in a frail elderly person.

Sheet metal

Sheet metal is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are constructed with sheet metal. Thicknesses can vary significantly; extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.

Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter.

The thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous (iron based) metals and nonferrous metals such as aluminum or copper; copper thickness, for example is measured in ounces (and represents the thickness of 1 ounce of copper rolled out to an area of 1 square foot).

Trenton, New Jersey

Trenton is the capital city of the U.S. state of New Jersey and the county seat of Mercer County, as well as briefly the former capital of the United States. The city's metropolitan area is grouped with the New York metropolitan area by the United States Census Bureau, but directly borders the Philadelphia metropolitan area and is part of the Federal Communications Commission's Philadelphia Designated Market Area. As of the 2010 United States Census, Trenton had a population of 84,913, making it the state's 10th-largest municipality. The Census Bureau estimated that the city's population was 84,034 in 2014.

Trenton dates back at least to June 3, 1719, when mention was made of a constable being appointed for Trenton, while the area was still part of Hunterdon County. Boundaries were recorded for Trenton Township as of March 2, 1720, a courthouse and jail were constructed in Trenton around 1720 and the Freeholders of Hunterdon County met annually in Trenton. Trenton became New Jersey's capital as of November 25, 1790, and the City of Trenton was formed within Trenton Township on November 13, 1792. Trenton Township was incorporated as one of New Jersey's initial group of 104 townships by an act of the New Jersey Legislature on February 21, 1798. On February 22, 1834, portions of Trenton Township were taken to form Ewing Township. The remaining portion of Trenton Township was absorbed by the City of Trenton on April 10, 1837. A series of annexations took place over a 50-year period, with the city absorbing South Trenton borough (April 14, 1851), portions of Nottingham Township (April 14, 1856), both the Borough of Chambersburg Township and Millham Township (both on March 30, 1888), as well as Wilbur Borough (February 28, 1898). Portions of Ewing Township and Hamilton Township were annexed to Trenton as of March 23, 1900.

Half marathon

A half marathon is a road running event of 21.0975 kilometres (13.1094 mi). It is half the distance of a marathon and usually run on roads. Participation in half marathons has grown steadily. One of the main reasons for this is that it is a challenging distance, but does not require the same level of training that a marathon does. In 2008, Running USA reported that the half marathon is the fastest growing type of race. A 2010 article by Universal Sports echoed the growing popularity of the distance. It is common for a half marathon event to be held concurrently with a marathon, using almost the same course with a late start, an early finish or shortcuts. The half marathon is also known as a 21K, 21.1K or 13.1 miles, although these values are rounded and not formally correct.

World record progression

World records in the half marathon are ratified by the International Association of Athletics Federations, the international governing body for the sport of athletics.

The official IAAF world record for men is 58:23, set by Zersenay Tadese of Eritrea on March 21, 2010 at the Lisbon half marathon in Portugal, and for women is 1:05:09, set by Florence Kiplagat of Kenya on February 15, 2015, in Barcelona, Spain.
