Worldwatch Institute

The Worldwatch Institute was a globally focused environmental research organization based in Washington, D. C. Worldwatch was named as one of the top ten sustainable development research organizations by Globescan Survey of Sustainability Experts. World watch Europe website ceased in 2017 and Worldwatch.org is unreachable as of January 2020. The mission of the Institute reads: Through research and outreach that inspire action, the Worldwatch Institute works to accelerate the transition to a sustainable world that meets human needs; the institute's top mission objectives are universal access to renewable energy and nutritious food, expansion of environmentally sound jobs and development, transformation of cultures from consumerism to sustainability, an early end to population growth through healthy and intentional childbearing. The Worldwatch Institute aims to inform policymakers and the public about the links between the world economy and its environmental support systems. Research conducted by the institute is interdisciplinary and global in scope.

Worldwatch's priority programs include: Building a low-carbon energy system that reduces the use of fossil fuels and lowers greenhouse gas emissions. Nourishing the Planet researches methods that create a sustainable food production system that provides a healthy, nutritious diet for all while sustaining the land and biological resources on which life depends; the project resulted in the Worldwatch Institute's flagship publication, State of the World 2011: Innovations that Nourish the Planet. Transforming economies and societies that meets human needs, promotes prosperity, is in harmony with nature. Worldwatch monitors human health, water resources, biodiversity and environmental security. 1974—The institute was founded by Lester Brown. 1975—The first Worldwatch Paper was published. 1984—First State of the World published. 1988—World Watch Magazine was launched. 1992—Vital Signs, Worldwatch's third annual series, was premiered. 2000—Christopher Flavin became President of Worldwatch in October. 2008—Worldwatch hosted the 20th Anniversary of the James E.

Tuoketuo Power Station

The Tuoketuo Power Station is the largest coal-fired power station in the world. The plant is located in Togtoh County, Inner Mongolia, China; the plant was commissioned in November 1995 by the Tuoketuo Power Company, which owns and operates the power station. The Tuoketuo Power Company is owned by three separate companies: Datang Power: 60% Beijing Power: 25% Huaneng Thermal Power: 15%The units of the facility were commissioned in six separate phases, each phase consisting of two units, rated at 600 MW each, all of which run on coal; the 1st and 2nd units were commissioned in June and July 2003, the 3rd and 4th units were commissioned in July and September 2004, the 5th and 6th units were commissioned in September and November 2005, the 7th and 8th units were commissioned in June 2006 and 9th and 10th units were commissioned in 2011. Two more 660 MW ultra-supercritical units were commissioned in 2017. All of the generated power is delivered to Beijing via 500-kV transmission lines. Two additional units of 300 MW each were commissioned, of which the generated power is used for the operations of the power plant itself, not used or delivered outside the facility.

With the addition of the final stage, it became the largest thermal power station in the world. The interval of 50 days between the commissioning of the two units of Phase I set a new record of the shortest construction time among comparable units in the North China region; the power plant exploits coal from the Junggar Coalfield 50 km away, meets its water requirements by pumping its needs from the Yellow River, located 12 km away.

Rotterdam (town), New York

Rotterdam is a town in Schenectady County, New York, United States. The population was 29,094 at the 2010 census; the town of Rotterdam is in the south-central part of the county. It was founded by Dutch settlers, who named it after the port of Rotterdam in the Netherlands, where many immigrants last touched European grounds; the town borders the city of Schenectady. Situated near the eastern end of New York State's Heritage Corridor at what is known as the "Gateway to the West", the town of Rotterdam is linked with the early development of Schenectady. At that time the present town of Rotterdam served as the outlying farmlands and wood lots for the settlers. With few exceptions, these settlers made their homes in the stockade in Schenectady but went to their farmlands during the daytime; the lands now known as Rotterdam became Schenectady's third ward when that city was incorporated in 1798. Rotterdam retained that status when the county of Schenectady was chartered in 1809. During this period, a council of aldermen and assistants from each of the four wards governed the city of Schenectady.

In May 1819, the city council recommended that the third and fourth wards be separated out as towns, on December 31, a petition to the state legislature was drafted. The legislation was passed on April 14, 1820, the final day of the legislative session, creating the town of Rotterdam; the Dellemont-Wemple Farm was added to the National Register of Historic Places in 1973, the Enlarged Double Lock No. 23, Old Erie Canal in 2008. The Mabee House, at the Mabee Farm Historic Site, the oldest surviving house in the Mohawk Valley, was added to the National Register of Historic Places May 22, 1978, it is a property of the Schenectady County Historical Society, being donated by a last descendant in his particular line, Mr. George Eugene Franchere, on January 29, 1993, the 287th anniversary of the original deed, it is being operated as a living history museum, conducts school programs, events for the public. Rotterdam has been a good town for baseball. For many years they brought up teams that would do well in the little league tournaments and Babe Ruth tournaments.

They would have one team go on to win a national championship in the latter. In August 1977, the all star team Carman little league would go on to qualify for the little league World Series in Williamsport, Pennsylvania, they would go on to finish 4th. 3 years in 1980, the same boys from that Carman team, along with a few mixed in from Rotterdam little league would become Babe Ruth World Series champions. They clawed their way out of the losers bracket to defeat Hawaii in 2 games in one day for the title; the tournament took place in North Dakota. Years in 2014, a team from Rotterdam Babe Ruth, went on to go to the semifinals in the Mid-Atlantic Regional Baseball Tournament. Rotterdam is the home of a large Net Zero housing Complex The Mohawk River defines the northeast town line; the New York State Thruway passes through the town. According to the United States Census Bureau, the town has a total area of 36.4 square miles, of which 35.7 square miles is land and 0.77 square miles, or 2.11%, is water.

The Rotterdam Town Board consists of five members, including the Supervisor, a voting member.

Boundary (topology)

In topology and mathematics in general, the boundary of a subset S of a topological space X is the set of points which can be approached both from S and from the outside of S. More it is the set of points in the closure of S not belonging to the interior of S. An element of the boundary of S is called a boundary point of S; the term boundary operation refers to taking the boundary of a set. Notations used for boundary of a set S include bd, fr, ∂S; some authors use the term frontier instead of boundary in an attempt to avoid confusion with a different definition used in algebraic topology and the theory of manifolds. Despite widespread acceptance of the meaning of the terms boundary and frontier, they have sometimes been used to refer to other sets. For example, the term frontier has been used to describe the residue of S, namely S \ S. Felix Hausdorff named the intersection of S with its boundary the border of S. A connected component of the boundary of S is called a boundary component of S. There are several equivalent definitions for the boundary of a subset S of a topological space X: the closure of S minus the interior of S: ∂ S:= S ¯ ∖ S ∘ the intersection of the closure of S with the closure of its complement: ∂ S:= S ¯ ∩ ¯ the set of points p ∈ X such that every neighborhood of p contains at least one point of S and at least one point not of S: ∂ S:= Consider the real line R with the usual topology and Q, the subset of rationals.

One has ∂ = ∂ = ∂ = ∂∅ = ∅ ∂Q = R ∂ = These last two examples illustrate the fact that the boundary of a dense set with empty interior is its closure. In the space of rational numbers with the usual topology, the boundary of, where a is irrational, is empty; the boundary of a set may change if one changes the topology. For example, given the usual topology on R2, the boundary of a closed disk Ω = is the disk's surrounding circle: ∂Ω =. If the disk is viewed as a set in R3 with its own usual topology, i.e. Ω = the boundary of the disk is the disk itself: ∂Ω = Ω. If the disk is viewed as its own topological space the boundary of the disk is empty; the boundary of a set is closed. The boundary of the interior of a set as well as the boundary of the closure of a set are both contained in the boundary of the set. A set is the boundary of some open set; the boundary of a set is the boundary of the complement of the set: ∂S = ∂. The interior of the boundary of a closed set is the empty set. Hence: p is a boundary point of a set if and only if every neighborhood of p contains at least one point in the set and at least one point not in the set.

A set is closed if and only if it contains its boundary, open if and only if it is disjoint from its boundary. The closure of a set equals the union of the set with its boundary. S = S ∪ ∂S; the boundary of a set is only if the set is both closed and open. The interior of the boundary of the closure of a set is the empty set. Conceptual Venn diagram showing the relationships among different points of a subset S of Rn. A = set of limit points of S, B = set of boundary points of S, area shaded green = set of interior points of S, area shaded yellow = set of isolated points of S, areas shaded black = empty sets; every point of S is either a boundary point. Every point of S is either an accumulation point or an isolated point; every boundary point of S is either an accumulation point or an isolated point. Isolated points are always boundary points. For any set S, ∂S ⊇ ∂∂S, with equality holding if and only if the boundary of S has no interior points, which will be the case for example if S is either closed or open.

Since the boundary of a set is closed, ∂∂S = ∂∂∂S for any set S. The boundary operator thus satisfies a weakened kind of idempotence. In discussing boundaries of manifolds or simplexes and their simplicial complexes, one meets the assertion that the boundary of the boundary is always empty. Indeed, the construction of the singular homology rests critically on this fact; the explanation for the apparent incongruity is that the topological boundary is a different concept from the boundary of a manifold or of a simplicial complex.

China Eastern Airlines

China Eastern Airlines Corporation Limited known as China Eastern, is an airline headquartered in the China Eastern Airlines Building, on the grounds of Shanghai Hongqiao International Airport in Changning District, Shanghai. It is a major Chinese airline operating international and regional routes, its main hubs are at Shanghai Pudong International Airport and Shanghai Hongqiao International Airport. China Eastern Airlines is China's second-largest carrier by passenger numbers after China Southern Airlines. China Eastern and its subsidiary Shanghai Airlines became the 14th member of SkyTeam on 21 June 2011; the parent company of China Eastern Airlines Corporation Limited is China Eastern Air Holding Company. China Eastern Airlines was established on 25 June 1988 under the Civil Aviation Administration of China Huadong Administration. In 1997, China Eastern took over the unprofitable China General Aviation and became the country's first airline to offer shares on the international market. In 1998 it founded China Cargo Airlines in a joint venture with COSCO.

In March 2001, it completed the takeover of Great Wall Airlines. China Yunnan Airlines and China Northwest Airlines merged into China Eastern Airlines in 2003; the Chinese government has a majority ownership stake in China Eastern Airlines, while some shares are publicly held. On 20 April 2006 the media broke the news of a possible sale of up to 20% of its stake to foreign investors, including Singapore Airlines and Japan Airlines, with Singapore Airlines confirming that negotiations were underway. After receiving approval from the State Council of China, it was announced that on 2 September 2007 Singapore Airlines and Temasek Holdings would jointly acquire shares of China Eastern Airlines. On 9 November 2007 investors signed a final agreement to buy a combined 24% stake in China Eastern Airlines: Singapore Airlines would own 15.73% and Temasek Holdings an 8.27% stake in the airline. Singapore Airlines' pending entry into the Chinese market prompted the Hong Kong carrier Cathay Pacific to attempt to block the deal by buying a significant stake in China Eastern and voting down the deal together with Air China at the shareholders' meeting in December 2007.

However, on 24 September Cathay Pacific announced. Air China's parent company, state-owned China National Aviation Corporation, announced in January 2008 that it would offer 32% more than Singapore Airlines for the 24% stake in China Eastern complicating the deal that Singapore Airlines and Temasek had proposed. However, minority shareholders declined the offer made by Singapore Airlines, it is thought. On 11 June 2009, it was announced; the merger of China Eastern and Shanghai Airlines was expected to reduce excess competition between the two Shanghai-based carriers while consolidating Shanghai's status as an international aviation hub. In February 2010 the merger was completed. Shanghai Airlines became a wholly owned subsidiary of China Eastern Airlines. However, Shanghai Airlines retained its livery; the new combined airline was expected to have over half of the market share in Shanghai, the financial hub of China. China Eastern Airlines acquired China United Airlines in October 2010. In March 2012, it was announced that China Eastern was forging a strategic alliance with the Qantas Group to set up Jetstar Hong Kong, a new low cost airline to be based at Hong Kong International Airport, which would commence operations in 2013.

China Eastern would hold a 50% stake in the new airline, with the Qantas Group holding the other 50%, representing a total investment of US$198 million. However, in June 2015, the Hong Kong authority refused to issue operating license to Jetstar Hong Kong. China Eastern and Qantas subsequently announced the end of the investment. In April 2013, China Eastern got a temporary permit to operate in the Philippines, but the Civil Aviation Authority of the Philippines required them to obtain a technical permit and an airport slot. In 2012, China Eastern was awarded the “Golden Ting Award” at the China Capital Market Annual Conference 2012, recognizing it as one of the 50 most valuable Chinese brands by WPP and ranking in the top ten of FORTUNE China's CSR ranking 2013. On September 9, 2014, China Eastern introduced new livery. In 2015, the airline entered a partnership with Delta Air Lines in which Delta will buy a 3.55% share in China Eastern for $450 million. China Eastern from June 30, 2015, launched new service to the US, as the Skyteam member plans three weekly ChengduNanjingLos Angeles operation with Airbus A330-200 aircraft.

In 2017, China Eastern Airlines reported a net profit of CNY6.4 billion, up 41% over net income of CNY4.5 billion in 2016. China Eastern Airlines has a strong presence on routes in North America and Australia; the airline looks to exploit the domestic market potential as it boosts flight frequencies from Shanghai to other Chinese cities. The airline is accelerating the pace of international expansion by increasing flight frequencies to international destinations. In 2007 it began operations to New York City from Shanghai, making it the longest non-stop route for the airline. In 2016, China Eastern Airlines launched direct flights from Shanghai to Prague, Madrid and St. Petersburg. China Eastern Airlines has codeshare agreements with the following airlines: As of January 2020, the China Eastern Airlines fleet consists of the following aircraft: China Eastern Airlines
