Old Navy

Jeffersons stars Isabel Sanford and Sherman Helmsley appeared in a number of Old Navy television commercials in the late 1990s and early 2000s. Rather, plum is derived from the Old English word plume. Magic remains an informal mascot of the company, though Donovan has since passed away. The plum, however, does not get its name from this root. According to Gap Inc., Magic, a Airedale terrier mix, was rescued from the streets of San Jose. The Latin plumbum has given birth to a number of terms in the English language:. Another popular spokesperson was former Vogue editor Carrie Donovan, who often appeared in ads with company "spokesdog", Magic. The earliest pencils actually used lead, though 'pencil leads' have been made for the last couple of centuries from graphite, a naturally occurring form (allotrope) of carbon.

Old Navy is also known for its advertising campaigns featuring celebrities such as Morgan Fairchild and hip hop artist Lil Kim. For that reason many universities do not hand out lead-containing samples to women for instructional laboratory analyses. A common tagline used in their campaigns is the widely recognized "(insert clothing article here) for the whole family!". Lead is considered to be particularly harmful for women's ability to reproduce. In sharp contrast to the Gap's advertisements, Old Navy's feature chipper family members sporting their clothing line while engaging in wholesome family activities, such as barbecueing. It has been suggested that what was known as "Devon colic" arose from the use of lead-lined presses to extract apple juice in the manufacture of cider. The most notable aspect of Old Navy's television advertisements are their satirical tone toward a retro time period, vaguely between 1940 and 1960. Lead salts used in pottery glazes have on occasion caused poisoning, when acid drinks, such as fruit juices, have leached lead ions out of the glaze.

In its Canadian stores, a similar shirt with the Canadian flag is sold. Paint containing lead has been withdrawn from sale in industralised countries, though many older houses may still contain substantial lead in their old paint: it is generally recommended that old paint should not be stripped by sanding, as this generates inhalable dust. Each year's shirt features a slightly-altered flag graphic with the year listed below. The concern about lead's role in mental retardation in children has brought about widespread reduction in its use (lead exposure has been linked to schizophrenia). The chain releases a shirt every summer emblazoned with an American flag. Main article: lead poisoning. Old Navy informally bills itself as an all-American brand. Although this has been banned in industrialized nations, there was a recent scandal involving lead-laced Mexican candy being eaten by children in California (http://www.ocregister.com/investigations/2004/lead/part1_printable.html).

Perhaps Old Navy's most recognizable product are their popular flip-flops. At one point in time, some lead compounds, because of their sweetness, were used by candy makers. In addition to clothing, Old Navy also sells a variety of accessories such as shoes, handbags, toys, hats, and sunglasses. The historical use of lead acetate (also known as sugar of lead) by the Roman Empire as a sweetener for wine is considered by some to be the cause of the dementia which affected many of the Roman Emperors. (And rivals like American Eagle, Abercrombie and Fitch and Hollister) Old Navy's stores contain specialized sections for infants, boys, girls, men, and women, and within these categories contain styles for many occasions. Long term exposure to lead or its salts (especially soluble salts or the strong oxidant PbO₂) can cause nephropathy, and colic-like abdominal pains. counterparts. Lead is a poisonous metal that can damage nervous connections (especially in young children) and cause blood and brain disorders.

Old Navy's target market largely consists of teenagers; accordingly, the clothing is trendy, yet more affordable than its other Gap Inc. The ranges of isotopic ratios for most natural materials are 14.0 - 30.0 for ²⁰⁶Pb/²⁰⁴Pb, 15.0 - 17.0 for ²⁰⁷Pb/²⁰⁴Pb, and 35.0 - 50.0 for ²⁰⁸Pb/²⁰⁴Pb, although numerous examples outside these ranges are reported in the literature. In 2001, Old Navy opened 12 stores in Canada, offerring the same products at slightly higher prices. Each is reported relative to ²⁰⁴Pb, the only non-radiogenic stable isotope. The online store, oldnavy.com, commenced operations in 2000. The corresponding half-lives of these decay schemes vary markedly: 4.47 × 10⁹, 7.04 × 10⁸ and 1.4 × 10¹⁰ years, respectively. While this motif was quickly dropped, many stores retain a warehouse-like/urban decor. ²⁰⁶Pb, ²⁰⁷Pb and ²⁰⁸Pb are all radiogenic, and are the end products of complex decay chains that begin at ²³⁸U, ²³⁵U and ²³²Th, respectively.

The name "Old Navy" was chosen because originally the stores were supposed to emulate the look and feel of a traditional military surplus store. Lead has four stable, naturally occurring isotopes: ²⁰⁴Pb (1.4%), ²⁰⁶Pb (24.1%), ²⁰⁷Pb (22.1%), and ²⁰⁸Pb (52.4%). As of 2005, Old Navy has more than 800 stores in many cities in the United States and Canada, the largest of which is in Chicago, Illinois. Main Article: Isotopes of lead. Launched in 1994 as a value chain, Old Navy opened its first store Colma, California. The molten lead bullion is then refined by additional smelting with air being passed over the lead to form a slag layer containing any remaining impurities and producing 99.9% pure lead. . The lead is then cooled in stages which causes the lighter impurites (dross) to rise to the surface where they can be removed.

Old Navy's corporate operations are with The Gap in San Francisco and San Bruno, California. The concentrate is sintered before being smelted in to produce a 97% lead concentrate. Old Navy is a brand of clothing and chain of stores that is owned by Gap Inc., which also owns the Gap, Banana Republic, and Forth & Towne brands. The concentrate, which can range from 50% to 60% lead, is dried and then treated using pyrometallurgy. The Froth flotation process separates the lead and other minerals from the waste rock (tailings) to form a concentrate. The ore is then treated using extractive metallurgy.

In mining, the ore is extracted by drilling or blasting and then crushed and ground. But more than half of the lead used currently comes from recycling. Other common varieties are cerussite (PbCO₃) and anglesite (PbSO₄). The main lead mineral is galena (PbS), which contains 86.6% lead.

Currently lead is usually found in ore with zinc, silver and (most abundantly) copper, and is extracted together with these metals. Native lead does occur in nature, but it is rare. Recently, lead use is being further curtailed by the RoHS directive. lead consumers' compliance with environmental regulations that significantly reduced or eliminated the use of lead in nonbattery products, including gasoline, paints, solders, and water systems.

Much of this shift was a result of the U.S. By the mid-1980s, a significant shift in lead end-use patterns had taken place. The English word "plumbing" also derives from this Latin root. Lead's symbol Pb is an abbreviation of its Latin name plumbum.

Lead pipes that bear the insignia of Roman emperors are still in service and many Roman "pigs" (ingots) of lead figure in Derbyshire lead mining history and in the history of the industry in other English centres. Alchemists thought that lead was the oldest metal and associated it with the planet Saturn. Lead was mentioned in the Book of Exodus. In the early bronze age lead was used with antimony and arsenic.

Lead has been used by humans for at least 7000 years, because it was (and continues to be) widespread and easy to extract, as well as easy to work with, being both highly malleable and ductile as well as easy to smelt. Lead is the only metal in which there is zero Thomson effect. Lead can be toughened by adding a small amount of antimony or other metals to it. sulfuric acid).

Because of this property, it is used to contain corrosive liquids (e.g. This true metal is highly resistant to corrosion. Lead has a bright luster and is a dense, ductile, very soft, highly malleable, bluish-white metal that has poor electrical conductivity. .

(But see the article on Bismuth, which has a half life so long it can be considered stable.). Lead has the highest atomic number of all stable elements. Lead is used in building construction, lead-acid batteries, bullets and shot, and is part of solder, pewter, and fusible alloys. A soft, heavy, toxic and malleable poor metal, lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air.

plumbum) and atomic number 82. Lead is a chemical element in the periodic table that has the symbol Pb (L.

S., and Edwards, R. L., Levine, A. Keisch, B., Feller, R. Aplomb comes from the French à plomb, meaning plumb vertical, and therefore confident and cool.

Plumbism is the medical term for lead poisoning. sense of plum (derived from plumb) meaning 'completely'. Plumb crazy may derive from the fact that lead poisoning can cause insanity; or, according to the Oxford English Dictionary, from a U.S. Plumbing the depths derives from the use of the lead weight to draw the sounding line down to the bottom of the water body (or to the end of the line if the water's really deep!).

Plumb wall is so-said because a plumb bob is used to find the vertical. Plumb bob or plummet, a small, pointed body of metal the weight of which is used to draw a string vertical under tension, refers to the fact that they were originally made from lead. Plumbing, or system of piping, derives from the fact that pipes were once made of lead. see isotope geochemistry.

See Category:Lead minerals. Lead is used as electrodes in the process of electrolysis. Tetraethyl lead has been used in leaded fuels to reduce engine knocking; however, this is no longer common practice in the Western World due to health concerns. It changes the optical characteristics of the glass and reduces the transmission of radiation.

Lead glass is comprised of 12-28% lead. for lead cooled fast reactors. Molten lead is used as a coolant, eg. Lead is used as shielding from radiation.

[1]. Because of the dangers, European and North American manufacturers use more expensive alternatives such as zinc. Lead is used in some candles to treat the wick to ensure a longer, more even burn. Lead is used as projectiles for firearms and fishing sinkers because of its density, low cost verse alternative products and ease of use due to relatively low melting point.

Lead sticks were used as pencils but has been replaced by graphite for the last 450 years. Lead was used for plumbing in Ancient Rome and water mains and service pipes up until the early 1970's. Lead is used as a coloring element in ceramic glazes, notably in the colors red and yellow. Lead was used as a pigment in Lead paint for white as well as yellow and red colors.

Lead is a major constituent of the Lead-acid battery used extensively in car batteries.
