In 2011, the only incorporated territory of the U.S. is neither an organized possession nor populated — Palmyra Atoll, the unorganized territory in equatorial waters far south of the State of Hawaii. The atoll under international law is an incorporated territory by 'explorers claim' and after serving in World War II as a supply and patrol base is only used today by a variable number of staff and researchers. The atoll also happens to be unorganized because it has no permanent occupants to petition for change, just the (rotating) assigned and visiting federal employees.
The District of Columbia is functionally similar to an incorporated territory, being fully a part of the United States as a non-state, but is classified separately as it was established under the unique constitutional provision for a federal capital rather than through Congressional authority over federal territory generally.
All other current U.S. territories are unincorporated (meaning that they are not fully part of the United States, with all aspects of the United States Constitution applying automatically), whereas other former incorporated territories are now states.

Coregency
A coregency (or co-principality) is the situation where a monarchical position (such as king, queen, emperor or empress), normally held by only a single person, is held by two.
Historical examples of this include the coregency of Frederick I of Austria and Louis the Bavarian over the Kingdom of Germany, and the coregency of William and Mary over England (along with Wales), Scotland, and Ireland. It was also found in Sparta with two Kings, San Marino with two Captains Regent, the ancient Roman Empire (by determination of Hadrian) and the Byzantine Empire, Ancient Egypt and Nubia, in these cases as a balance between King and Queen, male and female. Jure uxoris Kings in Kingdoms such as Spain and Portugal can also be found (Ferdinand V and Isabella I of Castile, Philip I and Joanna of Castile, Peter III and Maria I of Portugal, etc.).
The city of Maastricht was under the joint jurisdiction (parage) of the duke of Brabant and the prince-bishop of Liège. In 1648 it became a real condominium of two independent states, the Principality of Liège and the republic of the United Provinces. The coregency of the last was no longer held by a person but by the Estates-General of the Netherlands (until 1794).
A similar situation still exists today in Andorra, which has two Princes (the Bishop of Urgel and the President of France).
Another example is in Ancient Egypt, mainly in the Middle Kingdom, the Pharaoh occasionally appointed his successor (often one of his sons) as coregent, or joint King, to ensure a smooth succession. The Pharaoh also did this when he was elderly or unable to rule his country on his own (such as the case of Thutmose III and Amenhotep II or Amenemhat I and Senusret I). The existence of the practice makes establishing firm dates in Egyptian chronology more of a challenge, as the lengths of coregencies are often uncertain and complicate the use of accepted regnal lengths to establish dates. Some of the Queens of Egypt rose to a status of equal to the God-Kings, becoming co-rulers and / or at least as important in religious affairs, and were even portrayed with the same size as their male consort and even with the same size as the other Gods of Egypt. Such were the cases of Hatshepsut, Nefertiti, Nefertari and the Nubian Egyptian Queens. In the Ptolemaic Dynasty women finally rose to become equal co-rulers with men and even challenging them in order to become their respective consorts. This was due to a progressive improvement of the already high status of women in the Egyptian society, as well as to the religious principle of balance (Maat) between male and female. In Nubia, Queens like Amanishakheto and Amanitore were crowned alongside Kings at Dangeil and had both their pyramids at Mero? with the same height and side by side, and exerced power at the same level, even commanding armies. In Ethiopia, Kandakes also reached and hold this or a similar status.
In the book The Mysterious Numbers of the Hebrew Kings, Edwin R. Thiele proposed coregency as a possible explanation for discrepancies in the dates given in the Hebrew Bible for the reigns of the kings of Israel and Judah. At least one coregency is explicitly documented in the Bible: the coronation of King Solomon occurred before the death of his father David. Some Kings of Egypt, specially during the Twelfth Dynasty, also practised this custom, by associating their own sons in order to both prepare them for the office and prevent anyone else from usurping the throne, specially during its earlier days.

Week News Abstract For SFP Series in 10GTEK: Counties of England
Counties of England are areas used for the purposes of administrative, geographical and political demarcation. For administrative purposes, England outside Greater London and the Isles of Scilly is divided into 83 counties. The counties may consist of a single district or be divided into several districts. As of April 2009, 27 of these counties are divided into districts and have a county council. Six of the counties, covering the major conurbations, are known as metropolitan counties, which do not have county councils, although some functions are organised on a county-wide basis by the lower-tier districts (or metropolitan boroughs) acting jointly.Much of Northumbria was also shired, the best known of these counties being Hallamshire and Cravenshire. The Normans did not use these divisions, and so they are not generally regarded as ancient counties. The huge county of Yorkshire was a successor to the Viking Kingdom of York, and at the time of the Domesday Book in 1086 it was considered to include what was to become northern Lancashire, as well as parts of Cumberland, and Westmorland. Most of the later Cumberland and Westmorland were under Scottish rule until 1092. After the Norman Conquest in 1066 and the harrying of the North, much of the North of England was left depopulated and was included in the returns for Cheshire and Yorkshire in the Domesday Book.[26] However, there is some disagreement about the status of some of this land. The area in between the River Ribble and the River Mersey, referred to as "Inter Ripam et Mersam" in the Domesday Book,[27] was included in the returns for Cheshire.[28] Whether this meant that this land was actually part of Cheshire is however not clear.[27][29][30][31][32] Additionally, the Domesday book included as part of Cheshire, areas that later became part of Wales, including the two hundreds of Atiscross and Exestan, and the southern part of Duddestan Hundred (as it was known as the time), which later became known as Maelor Saesneg, and (later still) "Flintshire Detached" (see Flintshire (historic)),[33] The Northeast, or Northumbria, land that later became County Durham and Northumberland, was left unrecorded.

life
The PETM is accompanied by a mass extinction of 35-50% of benthic foraminifera (especially in deeper waters) over the course of ~1,000 years - the group suffering more than during the dinosaur-slaying K-T extinction. Contrarily, planktonic foraminifera diversified, and dinoflagellates bloomed. Success was also enjoyed by the mammals, who radiated profusely around this time.
The deep-sea extinctions are difficult to explain, as many were regional in extent (mainly affecting the north Atlantic). General hypotheses such as a temperature-related reduction in oxygen availability, or increased corrosiveness due to carbonate-undersaturated deep waters, are insufficient as explanations. The only factor which was global in extent was an increase in temperature, and it appears that the majority of the blame must rest upon its shoulders. Regional extinctions in the North Atlantic can be attributed to increased deep-sea anoxia, which could be due to the slowdown of overturning ocean currents,[12] or the release and rapid oxidation of large amounts of methane.[20][verification needed]
In shallower waters, it's undeniable that increased CO2 levels result in a decreased oceanic pH, which has a profound negative effect on corals.[21] Experiments suggest it is also very harmful to calcifying plankton.[22] However, the strong acids used to simulate the natural increase in acidity which would result from elevated CO2 concentrations may have given misleading results, and the most recent evidence is that coccolithophores (E. huxleyi at least) become more, not less, calcified and abundant in acidic waters.[23] Interestingly, no change in the distribution of calcareous nanoplankton such as the coccolithophores can be attributed to acidification during the PETM.[23] Acidification did lead to an abundance of heavily calcified algae[24] and weakly calcified forams.[25]
The increase in mammalian abundance is intriguing. There is no evidence of any increased extinction rate among the terrestrial biota. Increased CO2 levels may have promoted dwarfing[26] – which may (perhaps?) have encouraged speciation. Many major mammalian orders – including the Artiodactyla, horses, and primates – appeared and spread across the globe 13,000 to 22,000 years after the initiation of the PETM.[26]

Origins of the Exodus story
While the story in the books of Exodus, Numbers and Deuteronomy is the best-known account of the Exodus, there are over a hundred and fifty references scattered through the Bible, and the only significant body of work that does not mention it is the Wisdom literature.[3] The earliest mentions are in the prophets Amos (possibly) and Hosea (certainly), both active in 8th century Israel; in contrast Proto-Isaiah and Micah, both active in Judah at much the same time, never do; it thus seems reasonable to conclude that the Exodus tradition was important in the northern kingdom in the 8th century, but not in Judah.[4] In a recent work, Stephen C. Russell traces the 8th century prophetic tradition to three originally separate variants, in the northern kingdom of Israel, in Trans-Jordan, and in the southern kingdom of Judah. Russell proposes different hypothetical historical backgrounds to each tradition: the tradition from Israel, which involves a journey from Egypt to the region of Bethel, he suggests a memory of herders who could move to and from Egypt in times of crisis; for the Trans-Jordanian tradition, which focuses on deliverance from Egypt without a journey, he suggests a memory of the withdrawal of Egyptian control at the end of the Late Bronze Age; and for Judah, where the tradition is preserved in the Song of the Sea, he suggests the celebration of a military victory over Egypt, although it is impossible to suggest what this victory may have been.

Week News Abstract For SFP Series in 10GTEK:Etymology of Cymru
The modern Welsh name for themselves is Cymry, and Cymru is Welsh for "Land of the Cymry". The etymological origin of Cymry is from the Brythonic word combrogi, meaning "fellow-countrymen".[10] The use of the word Cymry as a self-designation derives from the post-Roman Era relationship of the Welsh with the Brythonic-speaking peoples of northern England and southern Scotland, the peoples of Yr Hen Ogledd (English: The Old North). In its original use, it amounted to a self-perception that the Welsh and the "Men of the North" were one people, exclusive of all others.[11] In particular, the term was not applied to the Cornish or the Breton peoples, who are of similar heritage, culture, and language to both the Welsh and the Men of the North. The word came into use as a self-description probably before the 7th century.[12] It is attested in a praise poem to Cadwallon ap Cadfan (Moliant Cadwallon, by Afan Ferddig) c. 633. In Welsh literature, the word Cymry was used throughout the Middle Ages to describe the Welsh, though the older, more generic term Brythoniaid continued to be used to describe any of the Britonnic peoples (including the Welsh) and was the more common literary term until c. 1100. Thereafter Cymry prevailed as a reference to the Welsh. Until c. 1560 Cymry was used indiscriminately to mean either the people (Cymry) or their homeland (Cymru).
The Latinised forms of these names are Cambrian or Cambric ("Welsh") and Cambria ("Wales"). They survive as lesser-used alternative names for Wales, Welsh and the Welsh people. Examples include the Cambrian Mountains (which cover most of Wales), the newspaper Cambrian News, as well as the organisations Cambrian Airways, Cambrian Railways and Cambrian Archaeological Association. Outside Wales, this form survives as the name of Cumbria in North West England, which was once a part of Yr Hen Ogledd. This form also appears at times in literary references, perhaps most notably in the pseudohistorical Historia Regum Britanniae of Geoffrey of Monmouth, where the character of Camber is described as the eponymous King of Cymru.Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to iron) is the last nuclear fusion reaction that is exothermic. This allows radioactive nickel to become the last element to be produced before collapse of a supernova leads to events that scatters this precursor radionuclide of iron into space.

Arthur Balfour
Arthur James Balfour, 1st Earl of Balfour, KG, OM, PC, DL (pronunciation: bal-foor ; 25 July 1848 – 19 March 1930) was a British Conservative politician and statesman. He served as the Prime Minister of the United Kingdom from July 1902 to December 1905, and was later Foreign Secretary in 1916–1919.
Born in Scotland and educated as a philosopher, Balfour first entered parliament in the 1874 general election. At first seen as something of a dilettante, he attained prominence as Chief Secretary for Ireland from 1887–1891. In this post, he authored the Perpetual Crimes Act (1887) (or Coercion Act) aimed at the prevention of boycotting, intimidation and unlawful assembly in Ireland during the Irish Land War.
Balfour succeeded his uncle Lord Salisbury as Prime Minister and Conservative Party leader in July 1902 (Balfour had been Conservative leader in the House of Commons since 1891). As Prime Minister, Balfour oversaw such events as the Entente Cordiale, but his party was split over tariff reform and in December 1905 he relinquished power to the Liberals. The general election the following January was a disaster for the Conservatives and their Liberal Unionist allies, left with a mere 157 seats in Parliament. Balfour himself lost his Manchester East seat and was rushed back to parliament in a by-election for the City of London constituency. He continued as Leader of the Opposition throughout the crisis over the Lloyd George People's Budget and the Parliament Act, but after failing to win either of the two General Elections in 1910 he resigned as leader in November 1911.
He returned to the Cabinet as First Lord of the Admiralty in the coalition government formed in May 1915, then in David Lloyd George's coalition government he was Foreign Secretary (1916–1919). In this post, he authored the Balfour Declaration of 1917, supporting the establishment of a Jewish homeland in Palestine, and for which his name perhaps remains best known today. Balfour retired from the House of Commons at the 1922 general election, and was granted an Earldom. In the late 1920s he served as an elder statesman in the second government of Stanley Baldwin.

Immanence
Immanence refers to philosophical and metaphysical theories of divine presence, in which the divine is seen to be manifested in or encompassing of the material world. It is often contrasted with theories of transcendence, in which the divine is seen to be outside the material world. It is usually applied in monotheistic, pantheistic, or panentheistic faiths to suggest that the spiritual world permeates the non-spiritual.
Immanence is generally associated with mysticism and mystical sects[citation needed], but most religions have elements of both immanent and transcendent belief in their doctrines. Major faiths commonly devote significant philosophical efforts to explaining the relationship between immanence and transcendence, but these efforts run the gamut from casting immanence as a characteristic of a transcendent God (common in Abrahamic faiths) to subsuming transcendent "personal" gods in a greater immanent being (Hindu Brahman) to approaching the question of transcendence as something which can only be answered through an appraisal of immanence (Buddhism, and some philosophical perspectives).

Week News Abstract For SFP Series in 10GTEK: Context
Dr. Kathy Gaughan, assistant professor of clinical sciences at Kansas State University's Veterinary Medical Teaching Hospital, points out that "the surgery stops the barking, but it doesn't address why the dog was barking in the first place."Gaughan notes that visitors to her clinic who request debarking are usually looking for a "quick fix". Gaughan states that, commonly, those who seek debarking live in apartments, or have neighbors who complain.Gaughan also counts "breeders with many dogs" among those who most often seek convenience devocalization. However, Dr. Gaughan does not agree with those who claim the procedure is cruel, stating "Recently, some animal advocates have asserted this surgery is cruel to the animal; some countries have even outlawed the procedure. I do not believe the surgical procedure is cruel; however, failing to address the underlying factors is inappropriate."
Some breeders seek the surgery in order to limit or diminish noise levels for personal reasons ranging from convenience to prevention; some breeders even seek the surgery for puppies prior to going to new homes.[citation needed] However, the fundamental flaw lies within the dog owner's capacity to make appropriate decisions based on their ability to properly provide and care for their breed of choice, which includes taking into consideration living conditions.[unbalanced opinion][citation needed]
Most dogs can be taught to offer more acceptable behaviors in lieu of barking and other noisy behaviors. It is important to remember that dogs may make noise while playing, when excited, stressed, bored, under or over exercised, and for any number of other reasons. Dog owners need to make educated decisions about the breed(s) and breed mixes they choose to bring into their homes by doing research on the history of the breed(s), the breed today, and the necessary requirements for the breed.
The Football League has been associated with a title sponsor since 1983.

Week News Abstract For SFP Series in 10GTEK: Food
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry, which is operated by multinational corporations that use intensive farming and industrial agriculture to maximize system output.
Food safety and food security are monitored by agencies like the International Association for Food Protection, World Resources Institute, World Food Programme, Food and Agriculture Organization, and International Food Information Council. They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food.
The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights (ICESCR), recognizing the "right to an adequate standard of living, including adequate food", as well as the "fundamental right to be free from hunger".
The Wal-Mart camel is the fossil of a prehistoric camel (Camelops sp.) found at a Wal-Mart construction site in Mesa, Arizona in 2007. Workers digging a hole for an ornamental citrus tree found the bones of two (juvenile and infant) animals that may have lived as long as 10,000 years ago. Arizona State University Geology Museum curator Brad Archer calls it an important and rare find for the area.Wal-Mart officials and Greenfield Citrus Nursery owner John Babiarz whose crew discovered the remains agreed that the bones will go directly to the Geology Museum at Arizona State University where further research and restoration of the fossils could be done. Camels lived in what is now Arizona until about 8,000 years ago.More camel bones were found in Gilbert, Arizona in May 2008.

Week News Abstract For SFP Series in 10GTEK: Resource
A resource is a source or supply from which benefit is produced. Typically resources are materials or other assets that are transformed to produce benefit and in the process may be consumed or made unavailable. From a human perspective a natural resource is anything obtained from the environment to satisfy human needs and wants.[1] From a broader biological or ecological perspective a resource satisfies the needs of a living organism (see biological resource).
The concept of resources has been applied in diverse realms, including with respect to economics, biology, computer science, land management, and human resources, and is linked to the concepts of competition, sustainability, conservation, and stewardship. In application within human society, commercial or non-commercial factors require resource allocation through resource management.
Resources have three main characteristics: 1) utility, 2) limited availability, and 3) potential for depletion or consumption. Resources have been variously categorized as biotic versus abiotic, renewable versus non-renewable, and potential versus actual, along with more elaborate classifications.
There are three fundamental differences between economic versus ecological views: the economic resource definition is human-centered (anthropocentric) and the ecological resource definition is nature-centered (biocentric or ecocentric); the economic view includes desire along with necessity, whereas the biological view is about basic biological needs; and economic systems are based on markets of currency exchanged for goods and services, whereas biological systems are based on natural processes of growth, maintenance, and reproduction.

Week News Abstract For SFP Series in 10GTEK: Subsonic and transonic behavior
As an aircraft enters the transonic speeds just below the speed of sound, an effect known as wave drag starts to appear. Using conservation of momentum principles in the direction normal to surface curvature, airflow accelerates around curved surfaces, and near the speed of sound the acceleration can cause the airflow to reach supersonic speeds. When this occurs, an oblique shock wave is generated at the point where the flow slows down back to subsonic speed. Since this occurs on curved areas, they are normally associated with the upper surfaces of the wing, the cockpit canopy, and the nose cone of the aircraft, areas with the highest local curvature.
Shock waves require energy to form. This energy is taken out of the aircraft, which has to supply extra thrust to make up for this energy loss. Thus the shocks are seen as a form of drag. Since the shocks form when the local air velocity reaches supersonic speeds over various features of the aircraft, there is a certain "critical mach" speed (or drag divergence mach number) where this effect becomes noticeable. This is normally when the shocks start generating over the wing, which on most aircraft is the largest continually curved surface, and therefore the largest contributor to this effect.
One of the simplest and best explanations of how the swept wing works was offered by Robert T. Jones: "Suppose a cylindrical wing (constant chord, incidence, etc.) is place in an airstream at an angle of yaw - ie., it is swept back. Now, even if the local speed of the air on the upper surface of the wing becomes supersonic, a shock wave cannot form there because it would have to be a sweptback shock - swept at the same angle as the wing - ie., it would be an oblique shock. Such an oblique shock cannot form until the velocity component normal to it becomes supersonic."
One limiting factor in swept wing design is the so-called "middle effect". If a swept wing is continuous - an oblique swept wing, the pressure iso-bars will be swept at a continuous angle from tip to tip. However, if the left and right halves are swept back equally, as is common practice, the pressure iso-bars on the left wing in theory will meet the pressure iso-bars of the right wing on the centerline at a large angle. As the iso-bars cannot meet in such a fashion, they will tend to curve on each side as the near the centerline, so that the iso-bars cross the centerline at right angles to the centerline. This causes an "unsweeping" of the iso-bars in the wing root region. To combat this unsweeping, German aerodynamicist Dietrich Küchemann proposed and had tested a local indentation of the fuselage above and below the wing root. This proved to not be very effective.During the development of the Douglas DC-8 airliner, uncambered airfoils were used in the wing root area to combat the unsweeping. Similarly, a decambered wing root glove was added to the Boeing 707 wing to create the Boeing 720.
At low Mach numbers induced drag dominates drag concerns. Airplanes during takeoff and gliders are most concerned with induced drag. One way to reduce induced drag is to increase the aspect ratio of the lifting surface. This is why gliders have such long, narrow wings. An ideal wing has infinite span and induced drag is reduced to a two dimensional property. At lower speeds, during takeoffs and landings, an oblique wing would be positioned perpendicular to the fuselage like a conventional wing to provide maximum lift and control qualities. As the aircraft gained speed, the wing would be pivoted to increase the oblique angle, thereby reducing the drag and decreasing fuel consumption.

Week News Abstract For SFP Series in 10GTEK:Celebes Sea
Hydrologically, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologically ocean basins are large geologic basins that are below sea level. Geologically, there are other undersea geomorphological features such as the continental shelves, the deep ocean trenches, and the undersea mountain ranges (for example, the mid-Atlantic ridge) which are not considered to be part of the ocean basins; while hydrologically, oceanic basins include the flanking continental shelves and shallow, epeiric seas.
Some consider the oceanic basins to be the complement to the continents, with erosion dominating the latter, and the sediments so derived ending up in the ocean basins. Others regard the ocean basins more as basaltic plains, than as sedimentary depositories, since most sedimentation occurs on the continental shelves and not in the geologically-defined ocean basins.
Hydrologically some geologic basins are both above and below sea level, such as the Maracaibo Basin in Venezuela, although geologically it is not considered an oceanic basin because it is on the continental shelf and underlain by continental crust.
Earth is the only planet with bimodal hypsography, reflecting the different kinds of crust, oceanic crust and continental crust. Oceans cover 70% of the Earth's surface. Because oceans lie lower than continents, the former serve as sedimentary basins that collect sediment eroded from the continents, known as clastic sediments, as well as precipitation sediments. Ocean basins also serve as repositories for the skeletons of carbonate- and silica-secreting organisms such as coral reefs, diatoms, radiolarians, and foraminifera.
Geologically, oceanic basins may be actively changing size or may be inactive, depending on whether there is a moving plate tectonic boundary associated with it. The elements of an active - and growing - oceanic basin include an elevated mid-ocean ridge, flanking abyssal hills leading down to abyssal plains. The elements of an active oceanic basin often include the oceanic trench associated with a subduction zone.
The Atlantic ocean and the Arctic ocean are good examples of active, growing oceanic basins, whereas the Mediterranean Sea is shrinking. The Pacific Ocean is also an active, shrinking oceanic basin, even though it has both spreading ridge and oceanic trenches. Perhaps the best example of an inactive oceanic basin is the Gulf of Mexico, which formed in Jurassic times and has been doing nothing but collecting sediments since then. The Sea of Japan and Bering Sea are also good examples of inactive oceanic basins.
The border between the Celebes and the Sulu Sea is at the Sibutu-Basilan Ridge. Strong ocean currents, deep sea trenches and seamounts, combined with active volcanic islands, result in complex oceanographic features.
