Finn River (County Fermanagh and County Monaghan)
The Finn River (Irish: An Fhinn or Abhainn na Finne), also known as the River Finn, is a small river that flows through parts of County Fermanagh and County Monaghan in the south of Ulster, the northern province in Ireland. Part of the river forms the boundary between County Fermanagh and County Monaghan, thus forming a short part of the border between Northern Ireland and the Republic of Ireland. Two very short stretches of the river, just north of Redhills and at Castle Saunderson, near Belturbet, also form part of the boundary between County Fermanagh and County Cavan. Parts of the river flow entirely within County Fermanagh, while other parts of the river flow entirely within County Monaghan. The Finn River should not be confused with the better known and much longer River Finn in County Donegal in the west of Ulster. The Finn River rises on the slopes of Slieve Beagh in the south-east of County Fermanagh, rising to the north of Roslea, a village also located in south-east Fermanagh. It initially flows in a southerly direction, meandering around both Rough Hill and Gola, two neighbouring townlands in the north-west of County Monaghan that are a short distance north-east of Roslea. The river then flows back into Fermanagh, skirting around the north-western, western and southern edges of Roslea and along the western edge of Spring Grove Forest, crossing back into County Monaghan beside New Bridge. At a place between New Bridge and Aghafin House, the river meanders around a sharp bend, flowing in a south-easterly direction for almost two miles, entirely within County Monaghan, between the townland of Aghafin, just north-east of Clones, and the townland of Nook, just south-east of Stonebridge. Thereafter, the river mainly flows in a south-westerly direction, all the way to its mouth on Upper Lough Erne. The river flows through Stonebridge and Analore, two hamlets in West Monaghan. It flows very close to Ballynure House, a now ruined Late Georgian residence just outside Analore. The Finn flows to the east, and then to the south, of Clones, the main town in West Monaghan. The river flows just to the north and north-west of the Hilton Park Demesne, near the village of Scotshouse, also in West Monaghan. The Finn flows through Wattlebridge, a hamlet in the south-east of County Fermanagh, then enters Upper Lough Erne nearby, entering the lough directly opposite Derrykerrib (Irish: Doire Ceirbe), an island and townland also in the south-east of County Fermanagh. The river flows into a narrow channel of the lough at this place, where the townland of Edergool in County Fermanagh meets the townland of Castlesaunderson Demesne, where Castle Saunderson is located, in County Cavan. Thus, half of the river's mouth is in County Fermanagh, while the other half is in County Cavan. The river's mouth, which is at the edge of the Castle Saunderson Demesne, is also very near the Lanesborough Demesne, a former demesne in the townland of Quivvy on the County Cavan shore of Upper Lough Erne. The Lanesborough Demesne, near Belturbet, is directly opposite the north-western shore of Derrykerrib Island. Traditionally, the Finn River was considered navigable for most of the year by certain types of river boat, from its mouth upstream as far as Cumber Bridge in the townland of Coolnalong (Irish: Cúil na Long), a bridge located between Scotshouse and Clones. The river meanders significantly throughout most of its course.

Galápagos Islands
The Galápagos Islands (official name: Archipiélago de Colón, other Spanish name: Las Islas Galápagos, Spanish pronunciation: [las ˈislas ɣaˈlapaɣos], local pronunciation: [laz ˈihlah ɣaˈlapaɣoh]), part of the Republic of Ecuador, are an archipelago of volcanic islands distributed on either side of the equator in the Pacific Ocean surrounding the centre of the Western Hemisphere. Located 906 km (563 mi) west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS Beagle. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection. The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000. The first recorded visit to the islands happened by chance in 1535, when Fray Tomás de Berlanga, the Bishop of Panamá, was surprised with this undiscovered land during a voyage to Peru to arbitrate in a dispute between Francisco Pizarro and Diego de Almagro. De Berlanga eventually returned to the Spanish Empire and described the conditions of the islands and the animals that inhabited them. The group of islands was shown and named "Insulae de los Galopegos" (Islands of the Tortoises) in Abraham Ortelius's atlas published in 1570. The first crude map of the islands was made in 1684 by the buccaneer Ambrose Cowley, who named the individual islands after some of his fellow pirates or after British royalty and noblemen. These names were used in the authoritative navigation charts of the islands prepared during the Beagle survey under captain Robert FitzRoy, and in Darwin's popular book The Voyage of the Beagle. The newly independent Republic of Ecuador took the islands from Spanish ownership in 1832, and subsequently gave them official Spanish names. The older names remained in use in English-language publications, including Herman Melville's The Encantadas of 1854. Administratively, Galapagos constitutes one of the provinces of Ecuador, made up of three cantons that bear the names of its most populated islands, namely: San Cristóbal, Santa Cruz and Isabela.

Tier-Scalable Reconnaissance
Tier-Scalable Reconnaissance is the term for an approach to deploying and controlling vehicles in multiple areas of interest, such as in the exploration of planets or diverse regions on Earth. It is not a rigid or fixed paradigm, but is infinitely extensible. It uses hierarchical levels of oversight called tiers, each tier commanding or controlling the vehicles within the tier beneath it. The size of each tier can be scaled from one to many vehicles.

Mortuary Archaeology
Mortuary archaeology, also known as bioarchaeology, is the study of human remains in their archaeological context. Mortuary archaeology aims to generate an understanding of disease, migration, health, nutrition, gender, status, and kinship among past populations. Ultimately, these topics help to produce a picture of the daily lives of past individuals. Mortuary archaeology tends to focus how individuals can contribute to understanding the population. Mortuary archaeologists draw upon the humanities, as well as social and hard sciences to have a full understanding of the individual. Mortuary archaeologists also use living groups to their advantage when studying populations that are no longer living. Mortuary archaeologists also are involved in conflict archaeology, and study mass burials from different historical events, like World War II and the Guatemalan genocide. These particular events will deal with comingled individuals. However, not all events are involved in mass burials or of historic context. One instance of a single individual involved in conflict, is that of Otzi. This is an example of a single individual that had been shot and killed. There are different methods that contribute to mortuary archaeology including analyzing different burial techniques between and within populations and creating a biological profile of the individual(s).

Teaching Sustainability in Planning and Design Education
Education for sustainable development (ESD) benefits school improvement and individual students, allowing them to ask critical questions about the status quo, clarify their values, and think systemically. In the fields of planning and design, including urban planning, regional planning, landscape architecture, and urban design, sustainability is vital to address the development dilemmas of environmental protection, urban development, economic activity, and social expectations. Design and planning decisions must consider a wide range of activities representing the goals of preservation, development, economic opportunities, social justice, and many others.

List of Minerals Approved by IMA (K)
This list includes those recognised minerals beginning with the letter K. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). The list is divided into groups: The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'. The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).

Sirente Crater
The Sirente crater (Italian: Cratere del Sirente) is a small shallow seasonal lake in Abruzzo, central Italy. The depression, which is located at the center of the Prati del Sirente, a mountainous highland north of the Sirente massif in the Apennines, is 13 km (8.1 mi) from the village of Secinaro. Its formation has prompted a number of theories in recent years. Although in the absence of shock-metamorphic and / or geochemical evidence it is not yet possible to confirm the meteoritic impact theory, no other theories for the origin of this geological structure have been proven yet. Interest in the Sirente crater began in the late 1990s after Swedish geologist Jens Ormö, an impact crater specialist, noticed ridges near the site that indicated a bolide collision. A research team named "The Sirente Crater Group" along with two scientists from the International Research School of Planetary Science of Pescara (IRSPS) began a detailed examination of the area. The team concluded the meteorite struck the Earth with the force of a small nuclear bomb; approximately one kiloton in yield. The blast would have created a mushroom cloud and shockwaves similar to a nuclear explosion.

Jeannette Expedition
The Jeannette Expedition of 1879–1881, officially called the U.S. Arctic Expedition, was an attempt led by George W. De Long to reach the North Pole by pioneering a route from the Pacific Ocean through the Bering Strait. The premise was that a temperate current, the Kuro Siwo, flowed northwards into the strait, providing a gateway to the Open Polar Sea and thus to the pole. This theory proved illusory; the expedition's ship, USS Jeannette and its crew of 33, was trapped by ice and drifted for nearly two years before she was crushed and sunk, north of the Siberian coast. De Long then led his 32 men on a perilous journey by sled, dragging the Jeannette's whaleboat and two cutters, eventually switching to these small boats to sail for the Lena Delta in Siberia. During this journey, and in the subsequent weeks of wandering in Siberia before rescue, 20 of the ship's complement died, including De Long. The chief exponent of the theory of a warm-water gateway to the North Pole was the German cartographer August Petermann. He encouraged James Gordon Bennett Jr., the proprietor of the New York Herald, to finance a polar expedition based on the untried Pacific route. Bennett acquired a former Royal Navy gunboat, the Pandora, and changed her name to Jeannette. De Long, whom Bennett chose to lead the expedition, was a serving naval officer with previous Arctic experience. Although essentially a private venture, in which Bennett paid all the bills, the expedition had the full support of the U.S. Government. Before departure the ship was commissioned into the U.S. Navy as USS Jeannette, and sailed under navy laws and discipline. Before its demise, the expedition discovered new islands—the De Long Islands—and collected valuable meteorological and oceanographic data. Although Jeannette's fate demolished the widely believed Open Polar Sea theory, the appearance in 1884 of debris from the wreck on the south-west coast of Greenland indicated the existence of an ocean current moving the permanent Arctic ice from east to west. This discovery inspired Fridtjof Nansen to mount his Fram expedition nine years later. A monument to the Jeannette's dead was erected at the United States Naval Academy in Annapolis, in 1890.
