# Briana Marela

Briana Marela Lizárraga is an American musician. Previously from Seattle, Marela is now based in Oakland, California.

## Biography

Marela grew up in Seattle and studied music technology while attending college in Olympia, Washington. She independently released two albums before signing with Jagjaguwar Records, who issued All Around Us in 2015. Alex Somers produced the album.
Her fourth album, Call It Love, was released in August 2017. Following the release of this album, Marela was dropped by Jagjaguwar, and she took time off from active performance as a solo artist while a student in the MFA program at Mills College. In April 2020, Marela's father, who lived in Peru, died, and due to the effects of the COVID-19 pandemic, she was unable to visit his home country for more than a year; these experiences influenced the content of her fifth album, You Are a Wave, which was released in September 2022.

# Acrossus rufipes

Acrossus rufipes, the night-flying dung beetle, is a species of scarab beetle. It was first recorded by the zoologist Carl Linnaeus as Acrossus rufipes in his 10th edition of Systema Naturae. The species was more recently considered a member of the genus Aphodius, but is now again classified as Acrossus rufipes.
Acrossus rufipes is found in the Palearctic and North America.

## Etymology

The species name rufipes is Latin for "red foot". It shares this name with a number of other species including the spider Sphodros rufipes.
Its British common name "the night-flying dung beetle" is given due to it being common for it to mistakenly find its way on its night-time flight from the dung-fields, to artificial lights among human habitation.

## Description

The outer body ranges from dark brown to black, while the legs are black with a red tinge. At 9–13 millimetres (0.35–0.51 in) in size, it is one of the largest of the genus Aphodius. It has ten ridges on each of its wing-covers (called elytra). It has a shovel-shaped head which it used to move the earth when it burrows.

## Behaviour

This species feeds and breeds in various types of dung, and in the British Isles it is usually seen between the months of April and October. The beetle is particularly sensitive to light. During the daytime hours or under artificial light, it instinctively burrows into the nearest moist soil or preferably fresh dung. From at least 4 centimetres (1.6 in) underneath the soil it is able to sense that night has fallen, since it soon emerges from the soil when all light is extinguished, and prepares for its night-time flight in search of mates or new sources of food.

## Symbiosis

The beetle has a symbiotic relationship with at least one species of mite, which is able to latch-on to the beetle's body beneath its hard shell, and remain securely attached when the beetle is burrowing or flying. The beetle thus provides the mites with safety and transport, while the mites are known to feed on mould in the dung, that would otherwise cause the beetle's source of food to decompose.

# Modau

The Modau is a 44-kilometre-long (27 mi) right tributary of the river Rhine running through the German state of Hesse. Historically, there have been many watermills on the river and its tributaries, giving rise to the name Mühltal ("Mill Valley"), a district through which the river flows. It passes through Darmstadt, and Ober-Ramstadt, and Pfungstadt, and flows into a branch of the Rhine in Stockstadt am Rhein.

## Erosion

Due to erosion of the river, it was needed to place various stones into the channel bed of the river to prevent abrasion, hydraulic action and early attrition
# Microgecko varaviensis

Microgecko varaviensis is a species of lizard in the family Gekkonidae. It is endemic to Iran.
# Questiomycin A

Questiomycin A is an antibiotic made by the fungus Penicillium expansum.
# Arabian Peninsular Reconnaissance Flight RAF
## Aden Protectorate Reconnaissance Flight

From 1956 Gloster Meteor FR Mk.9 aircraft from No. 208 Squadron RAF were deployed to Aden for operations against rebel tribesmen and Yemeni insurgents. This Squadron was withdrawn at the time of the Suez Crisis. 'C' Flight 208 Squadron returned in 1958 and was re-designated as the Aden Protectorate Reconnaissance Flight, formed on 1 August 1959, flying Meteor FR.9's. This flight was disbanded and renamed Arabian Peninsular Reconnaissance Flight on 1 October 1959.

## Arabian Peninsular Reconnaissance Flight

The Arabian Peninsular Reconnaissance Flight was formed at RAF Khormaksar when the Aden Protectorate Reconnaissance Flight was dis-banded and renamed on 1 October 1959. The flight continued to fly the Meteor FR.9's on tactical reconnaissance missions until it was disbanded in April 1960, handing the tactical recce mission over to No. 8 Squadron RAF, flying Hawker Hunter FR.10's.
# Atinia gens

The gens Atinia was a minor plebeian family at ancient Rome, which came to prominence during the late Republic. No members of this gens ever attained the consulship, although several were praetors in the early second century BC, beginning with Gaius Atinius Labeo 195.

## Origin

The nomen Atinius belongs to a class of gentilicia originally derived from surnames ending in -inus. The geographical and ethnic origin of this gens is not stated in any surviving authority, but if based on the town of Atina—originally a Volscian city in eastern Latium, subsequently occupied by the Samnites, then a Roman municipium following the Samnite Wars—it would follow the pattern of numerous other localities that gave rise to Roman gentes. With the exception of Titus Atinius, a figure ascribed to the mythology of the early Republic, all of the Atinii occurring in history belong to the period following the Second Punic War.

## Branches and cognomina

The only distinct family of this gens bore the cognomen Labeo, a surname originally referring to someone with thick or prominent lips, one of an abundant class of cognomina derived from the physical characteristics of an individual.

## Members

* Titus Atinius, according to legend, 491 BC had visions foretelling catastrophe unless the Great Games were held on a grand scale. The senate heeded his warning, and held the festival, averting divine wrath.
* Gaius Atinius Labeo, tribune of the plebs in 196 BC, required the senate to consider the claims of the consuls Lucius Furius Purpureo and Marcus Claudius Marcellus to a triumph separately, and passed a law establishing five colonies. Praetor peregrinus in 195, he was probably the author of the lex Atinia de usucapione.
* Gaius Atinius, one of the military tribunes in Gaul in 194 BC, where he served under the command of the consul Tiberius Sempronius Longus. He might be the same person as Gaius Atinius Labeo, praetor in 188 BC.
* Marcus Atinius, killed in Gaul while serving as praefectus socium under the consul Tiberius Sempronius Longus in 194 BC.
* Gaius Atinius Labeo, praetor in 190 BC, received the province of Sicilia.
* Gaius Atinius (Labeo), praetor in 188 BC, received Hispania Ulterior as his province.
* Marcus and Gaius Atinius, two of the main leaders of the Bacchanalia in 186 BC, arrested and brought before the consuls Spurius Postumius Albinus and Quintus Marcius Philippus for confession.

# Chambi National Park

Chambi National Park (sometimes Chambi Mountain National Park or Djebel Chambi National Park) is a national park in Tunisia's Kasserine Governorate. Located in the country's west-central part, the park is close to the border with Algeria. It protects the flora and fauna surrounding Mount Chambi (Djebel Chambi), the highest mountain peak (1,544m above sea level) in Tunisia.
The park is part of the Mont de Tebessa forest massif which spans the area from Kasserine to the Algerian border. The parks has no permanent rivers or streams, but it is one of the last refuges of the endangered Cuvier's gazelle and home to the vulnerable Barbary sheep. The park is also the site of notable plant life (holm oak and Cotoneaster nummularia, Aleppo pine, and Stipa tenacissima) and birds (including the Tunisian crossbill, the Egyptian vulture, Bonelli's eagle, and the peregrine falcon, among others).
In 1970, a 300-hectare (740-acre) fenced reserve was established to protect Cuvier's gazelle. In 1977, the park and its surrounding areas were designated a UNESCO biosphere reserve. The 6,723-hectare (16,610-acre) park was established as a national park in 1980.

# Microgenomates

The Microgenomatota or Microgenomates are a proposed supergroup of bacterial candidate phyla in the Candidate Phyla Radiation.
Organisms from the Microgenomates group have never been cultured in a lab; rather they have only been detected in the environment through genetic sequencing.
The Microgenomates group was originally discovered from sequences retrieved from the Yellowstone National Park hot spring "Obsidian Pool" and named OP11.
The group was later split into the additional bacterial phyla Absconditabacteria (SR1) and Parcubacteria (OD1) and then into over 11 more bacterial phyla, including Curtisbacteria, Daviesbacteria, Levybacteria, Gottesmanbacteria, Woesebacteria, Amesbacteria, Shapirobacteria, Roizmanbacteria, Beckwithbacteria, Collierbacteria, Pacebacteria.
# Quasisimple group

In mathematics, a quasisimple group (also known as a covering group) is a group that is a perfect central extension E of a simple group S. In other words, there is a short exact sequence
    $1\to Z(E)\to E\to S\to 1$
such that $E=[E,E]$, where $Z(E)$ denotes the center of E and [ , ] denotes the commutator.
Equivalently, a group is quasisimple if it is equal to its commutator subgroup and its inner automorphism group Inn(G) (its quotient by its center) is simple (and it follows Inn(G) must be non-abelian simple, as inner automorphism groups are never non-trivial cyclic). All non-abelian simple groups are quasisimple.
The subnormal quasisimple subgroups of a group control the structure of a finite insoluble group in much the same way as the minimal normal subgroups of a finite soluble group do, and so are given a name, component.
The subgroup generated by the subnormal quasisimple subgroups is called the layer, and along with the minimal normal soluble subgroups generates a subgroup called the generalized Fitting subgroup.
The quasisimple groups are often studied alongside the simple groups and groups related to their automorphism groups, the almost simple groups. The representation theory of the quasisimple groups is nearly identical to the projective representation theory of the simple groups.

## Examples

The covering groups of the alternating groups are quasisimple but not simple, for $n\geq 5.$
