Martian geysers (or CO2 jets) are putative sites of small gas and dust eruptions that occur in the south polar region of Mars during the spring thaw. "Dark dune spots" and "spiders" – or araneiforms – are the two most visible types of features ascribed to these eruptions. Martian geysers are distinct from geysers on Earth, which are typically associated with hydrothermal activity. These are unlike any terrestrial geological phenomenon. The reflectance (albedo), shapes and unusual spider appearance of these features have stimulated a variety of hypotheses about their origin, ranging from differences in frosting reflectance, to explanations involving biological processes. However, all current geophysical models assume some sort of jet or geyser-like activity on Mars. Their characteristics, and the process of their formation, are still a matter of debate. These features are unique to the south polar region of Mars in an area informally called the 'cryptic region', at latitudes 60° to 80° south and longitudes 150°W to 310°W; this 1 meter deep carbon dioxide (CO2) ice transition area—between the scarps of the thick polar ice layer and the permafrost—is where clusters of the apparent geyser systems are located. The seasonal frosting and defrosting of carbon dioxide ice results in the appearance of a number of features, such dark dune spots with spider-like rilles or channels below the ice, where spider-like radial channels are carved between the ground and the carbon dioxide ice, giving it an appearance of spider webs, then, pressure accumulating in their interior ejects gas and dark basaltic sand or dust, which is deposited on the ice surface and thus, forming dark dune spots. This process is rapid, observed happening in the space of a few days, weeks or months, a growth rate rather unusual in geology – especially for Mars. However, it would seem that multiple years would be required to carve the larger spider-like channels. There is no direct data on these features other than images taken in the visible and infrared spectra.

List of Fate/stay night characters
The Japanese adult visual novel Fate/stay night features a number of characters created by Type-Moon, some of whom are classified as Servants with special combat abilities. The characters listed have appeared mainly in two anime television series adaptations (Fate/stay night and Fate/stay night: Unlimited Blade Works) produced by Studio Deen and Ufotable respectively. A Fate/stay night: Unlimited Blade Works animated film was released prior to its TV series. Other characters from the franchise can be found on their respective titles, such as with Fate/Zero, Fate/Apocrypha, Fate/Extra Last Encore or Fate/kaleid liner Prisma Illya.

Grenada ( () grin-AY-də) is a sovereign state in the West Indies in the Caribbean Sea at the southern end of the Grenadines island chain. Grenada consists of the island of Grenada itself plus six smaller islands which lie to the north of the main island. It is located northwest of Trinidad and Tobago, northeast of Venezuela and southwest of Saint Vincent and the Grenadines. Its size is 348.5 square kilometres (134.6 sq mi), and it had an estimated population of 112,200 in July 2018. Its capital is St. George's. Grenada is also known as the "Island of Spice" due to its production of nutmeg and mace crops, of which it is one of the world's largest exporters. The national bird of Grenada is the critically endangered Grenada dove.

The national bird of Grenada is the critically endangered Grenada dove. Before the arrival of Europeans in the Americas, Grenada was inhabited by the indigenous Arawaks and later by the Island Caribs.. Christopher Columbus sighted Grenada in 1498 during his third voyage to the Americas. Although it was deemed the property of the King of Spain, there are no records to suggest the Spanish ever landed or settled on the island. Following several unsuccessful attempts by Europeans to colonise the island due to resistance from the Island Caribs, French settlement and colonisation began in 1650 and continued for the next century. On 10 February 1763, Grenada was ceded to the British under the Treaty of Paris. British rule continued until 1974 (except for a period of French rule between 1779 and 1783). From 1958 to 1962 Grenada was part of the Federation of the West Indies, a short-lived federation of British West Indian colonies. On 3 March 1967, Grenada was granted full autonomy over its internal affairs as an Associated State. Independence was granted on 7 February 1974, without breaking formal ties with the Commonwealth, under the leadership of Eric Gairy, who became the first Prime Minister of Grenada, with Queen Elizabeth as Head of State. In March 1979, the Marxist–Leninist New Jewel Movement overthrew Gairy's government in a popular bloodless coup d'état and established the People's Revolutionary Government (PRG), headed by Maurice Bishop as Prime Minister. Bishop was later executed by military hardliners, prompting a US led invasion in October 1983. Since then democratic governance has been restored and the island has remained politically stable.

Science studies
Science studies is an interdisciplinary research area that seeks to situate scientific expertise in broad social, historical, and philosophical contexts. It uses various methods to analyze the production, representation and reception of scientific knowledge and its epistemic and semiotic role. Similarly to cultural studies, science studies are defined by the subject of their research and encompass a large range of different theoretical and methodological perspectives and practices. The interdisciplinary approach may include and borrow methods from the humanities, natural and formal sciences, from scientometrics to ethnomethodology or cognitive science. Science studies have a certain importance for evaluation and science policy. Overlapping with the field of science, technology and society, practitioners study the relationship between science and technology, and the interaction of expert and lay knowledge in the public realm.

Copelatus bakewelli is a species of diving beetle. It is part of the genus Copelatus of the subfamily Copelatinae and the family Dytiscidae. It was described by J.Balfour-Browne in 1939.

Tsageri (Georgian: ცაგერი, Cageri) is a town in Georgia, located in Racha-Lechkhumi and Kvemo Svaneti region in the west of the country and serving as an administrative center of the homonymous district. Tsageri is located at 475 m above sea level, on the right bank of the Tskhenis-Tsqali, an affluent of the Rioni river. As of the 2014 census, the town had a population of approximately 1,320, mostly Georgians.
