Walmart Inc. is an American multinational retail corporation that operates a chain of hypermarkets, discount department stores, grocery stores. Headquartered in Bentonville, the company was founded by Sam Walton in 1962 and incorporated on October 31, 1969, it owns and operates Sam's Club retail warehouses. As of January 31, 2019, Walmart has 11,348 stores and clubs in 27 countries, operating under 55 different names; the company operates under the name Walmart in the United States and Canada, as Walmart de México y Centroamérica in Mexico and Central America, as Asda in the United Kingdom, as the Seiyu Group in Japan, as Best Price in India. It has wholly owned operations in Argentina, Chile and South Africa. Since August 2018, Walmart only holds a minority stake in Walmart Brasil, with 20% of the company's shares, private equity firm Advent International holding 80% ownership of the company. Walmart is the world's largest company by revenue—over US$500 billion, according to Fortune Global 500 list in 2018—as well as the largest private employer in the world with 2.2 million employees.
It is a publicly traded family-owned business. Sam Walton's heirs own over 50 percent of Walmart through their holding company, Walton Enterprises, through their individual holdings. Walmart was the largest U. S. grocery retailer in 2019, 65 percent of Walmart's US$510.329 billion sales came from U. S. operations. The company was listed on the New York Stock Exchange in 1972. By 1988, Walmart was the most profitable retailer in the U. S. and by October 1989, it had become the largest in terms of revenue. Geographically limited to the South and lower Midwest, by the early 1990s, the company had stores from coast to coast: Sam's Club opened in New Jersey in November 1989 and the first California outlet opened in Lancaster in July 1990. A Walmart in York, Pennsylvania opened in October 1990: the first main store in the Northeast. Walmart's investments outside North America have seen mixed results: its operations and subsidiaries in the United Kingdom, South America, China are successful, whereas its ventures in Germany and South Korea failed.
In 1945, businessman and former J. C. Penney employee Sam Walton bought a branch of the Ben Franklin stores from the Butler Brothers, his primary focus was selling products at low prices to get higher-volume sales at a lower profit margin, portraying it as a crusade for the consumer. He experienced setbacks because the lease price and branch purchase were unusually high, but he was able to find lower-cost suppliers than those used by other stores and was able to undercut his competitors on pricing. Sales increased 45% in his first year of ownership to US$105,000 in revenue, which increased to $140,000 the next year and $175,000 the year after that. Within the fifth year, the store was generating $250,000 in revenue; when the lease for the location expired, Walton was unable to reach an agreement for renewal, so he opened up a new store at 105 N. Main Street in Bentonville, naming it "Walton's Five and Dime"; that store is now the Walmart Museum. On July 2, 1962, Walton opened the first Walmart Discount City store at 719 W. Walnut Street in Rogers, Arkansas.
The building is now occupied by a hardware store and an antique mall, while the company's "Store #1" has since relocated to a larger discount store and now expanded to a Supercenter several blocks west at 2110 W. Walnut Street. Within its first five years, the company expanded to 24 stores across Arkansas and reached US$12.6 million in sales. In 1968, it opened its first stores outside Arkansas, in Sikeston and Claremore, Oklahoma; the company was incorporated as Wal-Mart, Inc. on October 31, 1969, changed its name to Wal-Mart Stores, Inc. in 1970. The same year, the company opened a home office and first distribution center in Bentonville, Arkansas, it had 38 stores operating with 1,500 sales of $44.2 million. It began trading stock as a publicly held company on October 1, 1970, was soon listed on the New York Stock Exchange; the first stock split occurred in May 1971 at a price of $47 per share. By this time, Walmart was operating in five states: Arkansas, Louisiana and Oklahoma; as the company moved into Texas in 1975, there were 125 stores with 7,500 employees and total sales of $340.3 million.
In the 1980s, Walmart continued to grow and by the company's 25th anniversary in 1987, there were 1,198 stores with sales of $15.9 billion and 200,000 associates. This year marked the completion of the company's satellite network, a $24 million investment linking all operating units with the Bentonville office via two-way voice and data transmission and one-way video communication. At the time, the company was the largest private satellite network, allowing the corporate office to track inventory and sales and to communicate to stores. In 1988, Walton was replaced by David Glass. Walton remained as Chairman of the Board. With the contribution of its superstores, the company surpassed Toys "R" Us in toy sales in 1998. While it was the third-largest retailer in the United States, Walmart was more profitable than rivals Kmart and Sears by the late 1980s. By 1990, it became the largest U. S. retailer by revenue. Prior to the summer of 1990, Walmart had no presence on the West Coast or in the Northeast, but in July and October that year, it opened its first stores in California and Pennsylvania, respectively.
By the mid-1990s, it was far and away the most powerful retailer in the U. S. and expanded into Mexico in 1991 and Canada in 1994
Maryland is a state in the Mid-Atlantic region of the United States, bordering Virginia, West Virginia, the District of Columbia to its south and west. The state's largest city is Baltimore, its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, the Chesapeake Bay State, it is named after the English queen Henrietta Maria, known in England as Queen Mary. Sixteen of Maryland's twenty-three counties border the tidal waters of the Chesapeake Bay estuary and its many tributaries, which combined total more than 4,000 miles of shoreline. Although one of the smallest states in the U. S. it features a variety of climates and topographical features that have earned it the moniker of America in Miniature. In a similar vein, Maryland's geography and history combines elements of the Mid-Atlantic and South Atlantic regions of the country. One of the original Thirteen Colonies of Great Britain, Maryland was founded by George Calvert, a Catholic convert who sought to provide a religious haven for Catholics persecuted in England.
In 1632, Charles I of England granted Calvert a colonial charter, naming the colony after his wife, Queen Mary. Unlike the Pilgrims and Puritans, who enforced religious conformity in their settlements, Calvert envisioned a colony where people of different religious sects would coexist under the principle of toleration. Accordingly, in 1649 the Maryland General Assembly passed an Act Concerning Religion, which enshrined this principle by penalizing anyone who "reproached" a fellow Marylander based on religious affiliation. Religious strife was common in the early years, Catholics remained a minority, albeit in greater numbers than in any other English colony. Maryland's early settlements and population centers clustered around rivers and other waterways that empty into the Chesapeake Bay, its economy was plantation-based, centered on the cultivation of tobacco. The need for cheap labor led to a rapid expansion of indentured servants, penal labor, African slaves. In 1760, Maryland's current boundaries took form following the settlement of a long-running border dispute with Pennsylvania.
Maryland was an active participant in the events leading up to the American Revolution, by 1776 its delegates signed the Declaration of Independence. Many of its citizens subsequently played key military roles in the war. In 1790, the state ceded land for the establishment of the U. S. capital of Washington, D. C. Although a slave state, Maryland remained in the Union during the U. S. Civil War, its strategic location giving it a significant role in the conflict. After the war, Maryland took part in the Industrial Revolution, driven by its seaports, railroad networks, mass immigration from Europe. Since the Second World War, the state's population has grown to six million residents, it is among the most densely populated states in the nation; as of 2015, Maryland had the highest median household income of any state, owing in large part to its close proximity to Washington, D. C. and a diversified economy spanning manufacturing, higher education, biotechnology. Maryland has been ranked as one of the best governed states in the country.
The state's central role in American history is reflected by its hosting of some of the highest numbers of historic landmarks per capita. Maryland is comparable in overall area with Belgium, it is the 42nd largest and 9th smallest state and is closest in size to the state of Hawaii, the next smaller state. The next larger state, its neighbor West Virginia, is twice the size of Maryland. Maryland possesses a variety of topography within its borders, contributing to its nickname America in Miniature, it ranges from sandy dunes dotted with seagrass in the east, to low marshlands teeming with wildlife and large bald cypress near the Chesapeake Bay, to rolling hills of oak forests in the Piedmont Region, pine groves in the Maryland mountains to the west. Maryland is bounded on its north by Pennsylvania, on its west by West Virginia, on its east by Delaware and the Atlantic Ocean, on its south, across the Potomac River, by West Virginia and Virginia; the mid-portion of this border is interrupted by District of Columbia, which sits on land, part of Montgomery and Prince George's counties and including the town of Georgetown, Maryland.
This land was ceded to the United States Federal Government in 1790 to form the District of Columbia.. The Chesapeake Bay nearly bisects the state and the counties east of the bay are known collectively as the Eastern Shore. Most of the state's waterways are part of the Chesapeake Bay watershed, with the exceptions of a tiny portion of extreme western Garrett County, the eastern half of Worcester County, a small portion of the state's northeast corner. So prominent is the Chesapeake in Maryland's geography and economic life that there has been periodic agitation to change the state's official nickname to the "Bay State", a nickname, used by Massachusetts for decades; the highest point in Maryland, with an elevation of 3,360 feet, is Hoye Crest on Backbone Mountain, in the southwest corner of Garrett County, near the bo
The chairman is the highest officer of an organized group such as a board, a committee, or a deliberative assembly. The person holding the office is elected or appointed by the members of the group, the chairman presides over meetings of the assembled group and conducts its business in an orderly fashion. In some organizations, the chairman position is called president, in others, where a board appoints a president, the two different terms are used for distinctly different positions. Other terms sometimes used for the office and its holder include chair, chairwoman, presiding officer, moderator and convenor; the chairman of a parliamentary chamber is called the speaker. The term chair is sometimes used in lieu of chairman, in response to criticisms that using chairman is sexist, it is used today, has been used as a substitute for chairman since the middle of the 17th century, with its earliest citation in the Oxford English Dictionary dated 1658–1659, only four years after the first citation for chairman.
Major dictionaries state that the word derives from a person. A 1994 Canadian study found the Toronto Star newspaper referring to most presiding men as "chairman", to most presiding women as "chairperson" or as "chairwoman"; the Chronicle of Higher Education uses "chairman" for men and "chairperson" for women. An analysis of the British National Corpus found chairman used 1,142 times, chairperson 130 times and chairwoman 68 times; the National Association of Parliamentarians adopted a resolution in 1975 discouraging the use of “chairperson” and rescinded it in 2017. The Wall Street Journal, The New York Times and United Press International all use "chairwoman" or "chairman" when referring to women, forbid use of "chair" or of "chairperson" except in direct quotations. In World Schools Style debating, male chairs are called "Mr. Chairman" and female chairs are called "Madame Chair"; the FranklinCovey Style Guide for Business and Technical Communication, as well as the American Psychological Association style guide, advocate using "chair" or "chairperson", rather than "chairman".
The Oxford Dictionary of American Usage and Style suggests that the gender-neutral forms are gaining ground. It advocates using "chair" to refer both to women; the Telegraph style guide bans the use of both "Chair" and "Chairperson" on the basis that "Chairman" is correct English. The word chair can refer to the place from which the holder of the office presides, whether on a chair, at a lectern, or elsewhere. During meetings, the person presiding is said to be "in the chair" and is referred to as "the chair". Parliamentary procedure requires that members address the "chair" as "Mr. Chairman" rather than using a name – one of many customs intended to maintain the presiding officer's impartiality and to ensure an objective and impersonal approach. In the United States, the presiding officer of the lower house of a legislative body, such as the House of Representatives, is titled the Speaker, while the upper house, such as the Senate, is chaired by a President. In his 1992 State of the Union address, then-U.
S. President George H. W. Bush used "chairman" for men and "chair" for women. In the British music hall tradition, the Chairman was the master of ceremonies who announced the performances and was responsible for controlling any rowdy elements in the audience; the role was popularised on British TV in the 1960s and 1970s by Leonard Sachs, the Chairman on the variety show The Good Old Days."Chairman" as a quasi-title gained particular resonance when socialist states from 1917 onward shunned more traditional leadership labels and stressed the collective control of soviets by beginning to refer to executive figureheads as "Chairman of the X Committee". Vladimir Lenin, for example functioned as the head of Soviet Russia not as tsar or as president but in roles such as "Chairman of the Council of People's Commissars of the Russian SFSR". Note in particular the popular standard method for referring to Mao Zedong: "Chairman Mao". In addition to the administrative or executive duties in organizations, the chairman has the duties of presiding over meetings.
Such duties at meetings include: Calling the meeting to order Determining if a quorum is present Announcing the items on the order of business or agenda as they come up Recognition of members to have the floor Enforcing the rules of the group Putting questions to a vote Adjourning the meetingWhile presiding, the chairman should remain impartial and not interrupt a speaker if the speaker has the floor and is following the rules of the group. In committees or small boards, the chairman votes along with the other members. However, in assemblies or larger boards, the chairman should vote only when it can affect the result. At a meeting, the chairman only has one vote; the powers of the chairman vary across organizations. In some organizations the chairman has the authority to hire staff and make financial decisions, while in others the chairman only makes recommendations to a board of directors, still others the chairman has no executive powers and is a spokesman for the organization; the amount of power given to the chairman depends on the type of organization, its structure, the rules it has created for itself.
If the chairman exceeds the given authority, engages in misconduct, or fails to perform t
Leadership in Energy and Environmental Design
Leadership in Energy and Environmental Design is one of the most popular green building certification programs used worldwide. Developed by the non-profit U. S. Green Building Council it includes a set of rating systems for the design, construction and maintenance of green buildings and neighborhoods that aims to help building owners and operators be environmentally responsible and use resources efficiently. Development of LEED began in 1993, spearheaded by Natural Resources Defense Council senior scientist Robert K. Watson; as founding chairman of the LEED Steering Committee, Watson led a broad-based consensus process until 2007, bringing together non-profit organizations, government agencies, engineers, builders, product manufacturers and other industry leaders. The LEED initiative was supported by a strong USGBC Board of Directors, chaired by Steven Winter from 1999 to 2003, active staff, including Nigel Howard. At that time, USGBC’s Senior Vice President of LEED, Scot Horst, became chair of the LEED Steering Committee before joining USGBC staff.
Early LEED committee members included USGBC co-founder Mike Italiano, architects Bill Reed and Sandy Mendler, builders Gerard Heiber and Myron Kibbe, engineer Richard Bourne. As interest in LEED grew, in 1996, engineers Tom Paladino and Lynn Barker co-chaired the newly formed LEED technical committee. From 1994 to 2015, LEED grew from one standard for new construction to a comprehensive system of interrelated standards covering aspects from the design and construction to the maintenance and operation of buildings. LEED has grown from six volunteers on one committee to 119,924 staff and professionals. LEED standards have been applied to 83,452 registered and certified LEED projects worldwide, covering around 13.8 billion square feet. Many U. S. federal agencies and states and local governments require or reward LEED certification. However, four states have banned the use of LEED in new public buildings, preferring other industry standards that the USGBC considers too lax. Unlike model building codes, such as the International Building Code, only members of the USGBC and specific "in-house" committees may add to, subtract from, or edit the standard, subject to an internal review process.
Proposals to modify the LEED standards are offered and publicly reviewed by USGBC's member organizations, which number 12,216. USGBC's Green Business Certification Inc. offers various accreditation to people who demonstrate knowledge of the LEED rating system, including LEED Accredited Professional, LEED Green Associate, since 2011, LEED Fellows, the highest designation for LEED professionals. GBCI certifies projects pursuing LEED. LEED has evolved since 1998 to more represent and incorporate emerging green building technologies; the pilot version, LEED New Construction v1.0, led to LEED NCv2.0, LEED NCv2.2 in 2005, LEED 2009 in 2009. LEED v4 was introduced in November, 2013; until October 31, 2016, new projects could choose between LEED 2009 and LEED v4. New projects registering after October 31, 2016 have been required to use LEED v4. LEED 2009 encompasses ten rating systems for the design and operation of buildings and neighborhoods. Five overarching categories correspond to the specialties available under the LEED professional program.
That suite consists of: Green Building Design & Construction LEED for New Construction LEED for Core & Shell LEED for Schools LEED for Retail: New Construction and Major Renovations LEED for HealthcareGreen Interior Design & Construction LEED for Commercial Interiors LEED for Retail: Commercial InteriorsGreen Building Operations & Maintenance LEED for Existing Buildings: Operations & MaintenanceGreen Neighborhood Development LEED for Neighborhood DevelopmentGreen Home Design and Construction LEED for Homes LEED forms the basis for other sustainability rating systems such as the Environmental Protection Agency's Labs21. To make it easier to follow LEED requirements, in 2009 USGBC helped BuildingGreen develop LEEDuser, a guide to the LEED certification process and applying for LEED credits written by professionals in the field. After four years of development, aligning credit across all LEED rating systems and weighing credits based on environmental priority, USGBC launched LEED v3, which consists of a new continuous development process, a new version of LEED Online, a revised third-party certification program and a new suite of rating systems known as LEED 2009.
Under LEED 2009, there are 100 possible base points distributed across six credit categories: "Sustainable Sites", "Water Efficiency", "Energy and Atmosphere", "Materials and Resources", "Indoor Environmental Quality", "Innovation in Design". Up to 10 additional points may be earned: four additional points may be received for Regional Priority Credits, six additional points for Innovation in Design. Buildings can qualify for four levels of certification: Certified: 40–49 points Silver: 50-59 points Gold: 60-79 points Platinum: 80 points and above The LEED 2009 performance credit system aims to allocate points "based on the potential environmental impacts and human benefits of each credit." These are weighed using the environmental impact categories of the United States Environmental Protection Agency's Tools for the Reduction and Assessment of Chemical and Other Environmental Impacts. and the environmental-impact weighting
Photovoltaic solar panels absorb sunlight as a source of energy to generate electricity. A photovoltaic module is a packaged, connected assembly of 6x10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications; the most common application of solar energy collection outside agriculture is solar water heating systems. Photovoltaic modules use light energy from the Sun to generate electricity through the photovoltaic effect; the majority of modules use wafer-based crystalline silicon cells or thin-film cells. The structural member of a module can either be the back layer. Cells must be protected from mechanical damage and moisture. Most modules are rigid, but semi-flexible ones based on thin-film cells are available; the cells must be connected electrically in one to another. A PV junction box is attached to the back of the solar panel and it is its output interface.
Externally, most of photovoltaic modules use MC4 connectors type to facilitate easy weatherproof connections to the rest of the system. USB power interface can be used. Module electrical connections are made in series to achieve a desired output voltage or in parallel to provide a desired current capability; the conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. Bypass diodes may be incorporated or used externally, in case of partial module shading, to maximize the output of module sections still illuminated; some special solar PV modules include concentrators in which light is focused by lenses or mirrors onto smaller cells. This enables the use of cells with a high cost per unit area in a cost-effective way. Solar panels use metal frames consisting of racking components, reflector shapes, troughs to better support the panel structure. In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by Alexandre-Edmond Becquerel.
Though the premiere solar panels were too inefficient for simple electric devices they were used as an instrument to measure light. The observation by Becquerel was not replicated again until 1873, when Willoughby Smith discovered that the charge could be caused by light hitting selenium. After this discovery, William Grylls Adams and Richard Evans Day published "The action of light on selenium" in 1876, describing the experiment they used to replicate Smith's results. In 1881, Charles Fritts created the first commercial solar panel, reported by Fritts as "continuous, constant and of considerable force not only by exposure to sunlight but to dim, diffused daylight." However, these solar panels were inefficient compared to coal-fired power plants. In 1939, Russell Ohl created the solar cell design, used in many modern solar panels, he patented his design in 1941. In 1954, this design was first used by Bell Labs to create the first commercially viable silicon solar cell; each module is rated by its DC output power under standard test conditions, ranges from 100 to 365 Watts.
The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 W module will have twice the area of a 16% efficient 230 W module. There are a few commercially available solar modules that exceed efficiency of 24% Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but cannot cover the entire solar range. Hence, much of the incident sunlight energy is wasted by solar modules, they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into six to eight different wavelength ranges that will produce a different color of light, direct the beams onto different cells tuned to those ranges; this has been projected to be capable of raising efficiency by 50%. A single solar module can produce only a limited amount of power. A photovoltaic system includes an array of photovoltaic modules, an inverter, a battery pack for storage, interconnection wiring, optionally a solar tracking mechanism.
Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multi-junction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells. The Spectrolab scientists predict that concentrator solar cells could achieve efficiencies of more than 45% or 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions; the best achieved sunlight conversion rate is around 21.5% in new commercial products lower than the efficiencies of their cells in isolation. The most efficient mass-produced solar modules have power density values of up to 175 W/m2. Research by Imperial College, London has shown that the efficiency of a solar panel can be improved by studying the light-receiving semiconductor surface with aluminum nanocylinders similar to the ridges on Lego blocks; the scattered light travels along a longer path in the semiconductor which means that more photons can be absorbed and converted into current.
Although these nanocylinders have been used the light scattering occurred in the near infrared region and visible light was absorbed strongly. Aluminum was found to have absorbed the ultraviolet part of the spectrum, while the visible and near infrared parts o
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus, independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, longer underwater endurance than breath-hold divers. Although the use of compressed air is common, a new mixture called enriched air has been gaining popularity due to its benefit of reduced nitrogen intake during repetitive dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, consist of one or more diving cylinders containing breathing gas at high pressure, supplied to the diver through a regulator, they may include additional cylinders for range extension, decompression gas or emergency breathing gas. Closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases; the volume of gas used is reduced compared to that of open circuit, so a smaller cylinder or cylinders may be used for an equivalent dive duration.
Rebreathers extend. Scuba diving may be done recreationally or professionally in a number of applications, including scientific and public safety roles, but most commercial diving uses surface-supplied diving equipment when this is practicable. Scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers. A scuba diver moves underwater by using fins attached to the feet, but external propulsion can be provided by a diver propulsion vehicle, or a sled pulled from the surface. Other equipment includes a mask to improve underwater vision, exposure protection, equipment to control buoyancy, equipment related to the specific circumstances and purpose of the dive; some scuba divers use a snorkel. Scuba divers are trained in the procedures and skills appropriate to their level of certification by instructors affiliated to the diver certification organisations which issue these certifications; these include standard operating procedures for using the equipment and dealing with the general hazards of the underwater environment, emergency procedures for self-help and assistance of a equipped diver experiencing problems.
A minimum level of fitness and health is required by most training organisations, but a higher level of fitness may be appropriate for some applications. The history of scuba diving is linked with the history of scuba equipment. By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered. Closed circuit equipment was more adapted to scuba in the absence of reliable and economical high pressure gas storage vessels. By the mid twentieth century, high pressure cylinders were available and two systems for scuba had emerged: open-circuit scuba where the diver's exhaled breath is vented directly into the water, closed-circuit scuba where the carbon dioxide is removed from the diver's exhaled breath which has oxygen added and is recirculated. Oxygen rebreathers are depth-limited due to oxygen toxicity risk, which increases with depth, the available systems for mixed gas rebreathers were bulky and designed for use with diving helmets; the first commercially practical scuba rebreather was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London.
His self contained breathing apparatus consisted of a rubber mask connected to a breathing bag, with an estimated 50–60% oxygen supplied from a copper tank and carbon dioxide scrubbed by passing it through a bundle of rope yarn soaked in a solution of caustic potash, the system giving a dive duration of up to about three hours. This apparatus had no way of measuring the gas composition during use. During the 1930s and all through World War II, the British and Germans developed and extensively used oxygen rebreathers to equip the first frogmen; the British adapted the Davis Submerged Escape Apparatus and the Germans adapted the Dräger submarine escape rebreathers, for their frogmen during the war. In the U. S. Major Christian J. Lambertsen invented an underwater free-swimming oxygen rebreather in 1939, accepted by the Office of Strategic Services. In 1952 he patented a modification of his apparatus, this time named SCUBA, which became the generic English word for autonomous breathing equipment for diving, for the activity using the equipment.
After World War II, military frogmen continued to use rebreathers since they do not make bubbles which would give away the presence of the divers. The high percentage of oxygen used by these early rebreather systems limited the depth at which they could be used due to the risk of convulsions caused by acute oxygen toxicity. Although a working demand regulator system had been invented in 1864 by Auguste Denayrouze and Benoît Rouquayrol, the first open-circuit scuba system developed in 1925 by Yves Le Prieur in France was a manually adjusted free-flow system with a low endurance, which limited its practical usefulness. In 1942, during th
Atlantic Station is a neighborhood on the northwestern edge of Midtown Atlanta, United States comprising a retail district, office space, condominiums and apartment buildings. First planned in the mid-1990s and opened in 2005, the neighborhood's 138 acres are located on the former brownfield site of the Atlantic Steel mill. Atlantic Station is located on the site of the Atlantic Steel mill, which opened in 1901; the steel mill was nearly closed in the mid-1970s, but it remained nominally operational to avoid the huge costs it would have required to remediate the soil contamination present after years of operation. Developer Jim Jacoby, who redeveloped Florida's Marineland, began putting the project together in 1997 when his company became the property contractor of the land; the redevelopment of the land into what is now Atlantic Station was financed by private investment, but was supplemented by a special tax district to pay for city tax bonds for public utilities. The development was planned to include 15,000,000 square feet of retail, residential space as well as 11 acres of public parks.
Its size encouraged the Postal Service to award the neighborhood its own ZIP code: 30363. Atlantic Station was designed with energy efficiency in mind and many of the buildings are LEED certified. Additionally, the project was developed to help mitigate urban sprawl and reduce air pollution by allowing many more people to live and work within walking distance of most everyday things they need, with many alternative transportation options nearby; the proposed BeltLine transit/greenway project is expected to pass within a few miles of the development. In October 2003, the first residents moved into the development; the 17th Street bridge was completed in January 2004 and the first round of retail establishments opened in October 2005. Atlantic Station received the EPA's 2004 Phoenix Award as the Best National Brownfield Redevelopment, as well as the Sierra Club's 2005 America's Best New Development Projects listing. In July 2005, a pre-dawn fire destroyed a large wood-frame residential building under construction.
Two days it was ruled arson after a major investigation. In addition to the destruction of the 65-unit Element building, only framed-in at the time, another 80 inhabited units at the Art Foundry across Mecaslin Street had damage to the facade, including scorching, broken windows, melted miniblinds. At least five million dollars of damage was done to the buildings, 18 cars parked on the street were destroyed and another 7 were damaged from the intense heat. In a joint venture, North American Properties Atlanta, founded by Mark Toro, CB Richard Ellis Investors closed on the purchase of Atlantic Station's retail component on December 31, 2010. Toro and the NAP management launched a social media blitz, attended community meetings and real estate symposiums to discuss challenges, such as crime, invite feedback. Toro's vision to transform Atlantic Station included new retail, new restaurants, better parking and a renewed effort to make Atlantic Station a destination for in-town residents. On October 1, 2015, Atlantic Station's retail core was sold to Hines Interest Limited Partnership with an unnamed joint financial partner.
Atlantic Station comprises three distinct areas that are lined along 17th Street between the Downtown Connector and Northside Drive, the District, the Commons, the Village. The District is. Opened on October 21, 2005, it was constructed in the style of an outdoor mall, with choices of shopping, a 16-screen Regal movie theater. Above the retail levels is an additional two to three stories of condominiums. With the 7,200-space parking garage underneath, the shopping area is pedestrian-friendly and many of the surface level streets are closed off for special events; the southwest corner of The District is home to the 26-story, 336-foot TWELVE Hotel and Residences Atlantic Station, completed in December 2005. In addition, townhomes constructed in 2004 line 16th Street one block south of The District; the District's office space is located along the six-lane 17th Street Corridor, is home to the 22-story tall 171 17th Street, known as the Wells Fargo Building and completed in 2004, the 17-story 201 17th Street, completed in 2007.
