Di-tert-butyl ether
Di-tert-butyl ether is a  tertiary ether, primarily of theoretical interest as the simplest member of the class of di-tertiary ethers.  Di-tertiary ethers are notoriously challenging to prepare because conventional SN,2 and dehydration methods favor elimination; as late as 1941, the existence of the molecule remained in doubt.

A mediocre-yielding synthesis for di-tert-butyl ether alkylates silver carbonate with tert-butyl chloride.

Tert-Butyl chloride
tert-Butyl chloride is the organochloride with the formula (CH3)3CCl.  It is a colorless, flammable liquid. It is sparingly soluble in water, with a tendency to undergo hydrolysis to the corresponding tert-butyl alcohol.  It is produced industrially as a precursor to other organic compounds.
1993 Southern Conference baseball tournament
The 1993 Southern Conference baseball tournament was held at College Park in Charleston, South Carolina, from April 28 through May 1. Second seeded Western Carolina won the tournament and earned the Southern Conference's automatic bid to the 1993 NCAA Division I baseball tournament. It was the Catamounts seventh tournament win.

The tournament used a double-elimination format. Only the top eight teams participate, so Furman was not in the field.

Hybrizyme
Hybrizyme is a term coined to indicate novel or normally rare gene variants (or alleles) that are associated with hybrid zones, geographic areas where two related taxa (e.g. species or subspecies) meet, mate, and produce hybrid offspring. The hybrizyme phenomenon is widespread and these alleles occur commonly, if not in all hybrid zones. Initially considered to be caused by elevated rates of mutation in hybrids, the most probable hypothesis infers that they are the result of negative (purifying) selection. Namely, in the center of the hybrid zone, negative selection purges alleles against hybrid disadvantage (e.g. hybrid inviability or infertility). Stated differently, any allele that will decrease reproductive isolation is favored and any linked alleles (genetic markers) also increase their frequency by genetic hitchhiking. If the linked alleles used to be rare variants in the parental taxa, they will become more common in the area where the hybrids are formed.

Reproductive isolation
The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They prevent members of different species from producing offspring, or ensure that any offspring are sterile. These barriers maintain the integrity of a species by reducing gene flow between related species.

The mechanisms of reproductive isolation have been classified in a number of ways. Zoologist Ernst Mayr classified the mechanisms of reproductive isolation in two broad categories: pre-zygotic for those that act before fertilization (or before mating in the case of animals) and post-zygotic for those that act after it. The mechanisms are genetically controlled and can appear in species whose geographic distributions overlap (sympatric speciation) or are separate (allopatric speciation).
Kidsty Pike
Kidsty Pike is a fell in the English Lake District, standing to the west of Haweswater Reservoir. It is a subsidiary top of Rampsgill Head, but has long achieved the status of a separate fell, thanks to its classic peaked profile. Wainwright followed this convention in his Pictorial Guide to the Lakeland Fells.

Haweswater Reservoir
Haweswater is a reservoir in the valley of Mardale, Cumbria in the Lake District, England. The man-made reservoir, which was created by damming the original natural lake, was completed by 1935. It raised the water level in the valley by 29 m (95 ft).

The valley was dammed by Manchester Corporation, after it had obtained permission from the UK Parliament through the passing of the Manchester Corporation Act 1919 (9 & 10 Geo. 5. c. cxix). The local act of Parliament was for the supply of drinking water to Manchester. However, the decision caused public outcry because the farming villages of Measand and Mardale Green would be lost when Mardale was flooded.

Construction work on the dam began in 1929. Haweswater was completely flooded by 1935. The reservoir is now owned and managed by United Utilities. It supplies about 25% of North West England's water supply.
Sthenistis
Sthenistis is a monotypic moth genus in the family Immidae. Its only species, Sthenistis gyrtoniformis, is found in Sri Lanka. Both the genus and species were described by George Hampson in 1896.

The wingspan is about 22 mm (0.87 in). The forewings are pale brown, thickly marked with short dark brown streaks in the interspaces, the inner margin paler, also the outer area except towards the costa. There are traces of an antemedial line appearing as a wedge-shaped mark on the inner margin and there is a dark speck at the lower angle of the cell, with an obscure oblique line from it to the inner margin. The hindwings are fuscous brown. Females have broader forewings, with the inner and outer areas prominently paler.

Immidae
Immoidea is a superfamily of pantropical moths containing only the family Immidae comprising ten genera with around 250 species, over half of them in the genus Imma. Many are brightly coloured and diurnal. The position of this group is currently uncertain within the group Obtectomera . The larvae feed on the leaves of dicotyledons and conifers including Podocarpus (Dugdale et al. 1999).
Kincade Fire
The Kincade Fire was a wildfire that burned in Sonoma County, California in the United States. The fire started northeast of Geyserville in The Geysers at 9:24 p.m. on October 23, 2019, and subsequently burned 77,758 acres (31,468 ha) until the fire was fully contained on November 6, 2019. The fire threatened over 90,000 structures and caused widespread evacuations throughout Sonoma County, including the communities of Geyserville, Healdsburg, Windsor, and Santa Rosa. The majority of Sonoma County and parts of Lake County were under evacuation warnings and orders. Lake county only had one evacuation order and that was the town of Middletown. The fire was the largest of the 2019 California wildfire season, and also the largest wildfire recorded in Sonoma County at the time before being surpassed by the LNU Lightning Complex fires in 2020.

LNU Lightning Complex fires
The LNU Lightning Complex fires were a large complex of wildfires that burned during the 2020 California wildfire season across much of the Wine Country area of Northern California – Lake, Napa, Sonoma, Solano, and Yolo Counties, from August 17 to October 2, 2020. The complex was composed of numerous lightning-sparked fires, most of which were small. While they ignited separately from each other, the Hennessey Fire eventually grew to merge with the Gamble, Green, Markley, Spanish, and Morgan fires, scorching 192,000 acres (777 km2) by itself, for a total burn area of 363,220 acres (1,470 km2) in the complex. The fire, which burned in the hills surrounding several large cities, such as Fairfield, Napa, and Vacaville, destroyed 1,491 structures and damaged a further 232. In all, six people were killed and another five injured. The LNU Lightning Complex is the seventh-largest wildfire in California history.

Gameplay is very similar to the gameplay of Rugrats: Royal Ransom and shares the same plot, released a year later.

Single-player video game
A single-player video game is a video game where input from only one player is expected throughout the gameplay. Video games in general can feature several game modes, including single-player modes designed to be played by a single player in addition to multi-player modes.

Most modern console games, PC games and arcade games are designed so that they can be played by a single player; although many of these games have modes that allow two or more players to play (not necessarily simultaneously), very few actually require more than one player for the game to be played. The Unreal Tournament series is one example of such.

Lviv during the Middle Ages
In the Middle Ages, Lviv was an important economic, cultural and political center of Ruthenia. Its history covers the period from the foundation of the fortress in the mid-13th century to the second half of the 16th century, when the Polish–Lithuanian Commonwealth was formed and the Jagiellonian dynasty was interrupted. The first written mention of Lviv dates back to 1256. From the 2nd half of the 13th century it was one of the largest cities of the Kingdom of Galicia–Volhynia, after 1341 — the center of the "Ruthenian Kingdom" within Poland. In 1370, Lviv was ceded to the Kingdom of Hungary, and in 1387, it returned to the Kingdom of Poland. After 1433, Lviv became the administrative center of the Ruthenian Voivodeship. The population of the medieval city was characterized by multi-ethnicity and multi-confessionalism, which often led to friction and open conflict between different communities.

Sifnos
Sifnos (Greek: Σίφνος) is an island municipality in the Cyclades island group in Greece. The main town, near the center, known as Apollonia (pop. 918 as of 2021), is home of the island's folklore museum and library. The town's name is thought to come from an ancient temple of Apollo on the site of the church of Panayia Yeraniofora.  The second-largest town is Artemonas, thought to be named after an ancient temple of Apollo's sister Artemis, located at the site of the church of Panayia Kokhi.  The village of Kastro, was the capital of the island during ancient times until 1836. It is built on top of a high cliff on the island's east shore and today has extensive medieval remains and is the location of the island's archeological museum. The port settlement, on the west coast of the island is known as Kamares.
