The story begins when Cathy is dumped by her boyfriend, Victor. The next morning she notices a strange mark on her arm, but sets it aside as a spider bite.

# Attila (clothing)

The attila is an elaborately braided Hungarian shell-jacket or short coat, decorated with lace and knots. Historically it was part of the uniform of the Hungarian cavalry known as hussars (or huszárs). It was a part of the everyday wear of rural men as well as members of the nobility and officials.
The attila was made in many styles and many colors including black, gray, blue, green, red and white. Some of these overlapped with the Turkish dolman. The origins of the attila are believed to go back to the 16th century when Hungarians adopted the practice of wearing their short coats slung on one shoulder. When worn in this fashion the jacket was often referred to as a pelisse. In cold or wet weather the attila could be buttoned across the chest and worn as a conventional jacket.
One possibly mythical account, reported by an English general, is that one night a Hungarian cavalry unit was attacked by the Turks and had no time to dress properly. Instead they just threw on their short coats half shouldered and went into battle. Supposedly the Turks on seeing the "flying sleeves of the short coats", thought that they were fighting men who had more than two arms, and fled.
Other accounts suggest that Hungarian hussars wore their short coat slung over one shoulder to provide limited protection from glancing sword blows. Earlier Hungarian horsemen had used slung animal skins as a shield in this way. After 1850 the Austro-Hungarian cavalry attila became longer. In 1892 the attila also became part of the Hungarian forester's ceremonial uniform. It was dark green or black with seven golden braids and golden buttons. During the late 18th and 19th centuries hussar regiments were raised in many European and Latin American armies and the fur trimmed pelisse, worn over a braided attila or dolman, often continued to be worn in the slung fashion described. By the mid-19th century the attila had become part of the ceremonial uniform of the Royal Netherlands East Indies Army
Michael Kovats, the Hungarian hussar, who recruited, trained, organized, and led some of the first American cavalry into battle, wore an attila as part of his uniform.

# 2022–23 División de Honor Juvenil de Fútbol

## Competition format

# Canasite

Canasite is a mineral whose name is derived from its chemical composition of calcium (Ca), sodium (Na), and silicon (Si). It was approved in 1959 by IMA.

## Properties

It is a relatively rare mineral. It occurs as aggregates in charoite, creating cabochons when contrasted against swirling purple charoite. It is extremely rare for canasite to be faceted. As crystals, it occurs in a size up to 10 cms, but in platy aggregates it can reach up to 20 cms in size. It is also granular. Twinning is usual, and can occur as polysynthetic, which is when multiple twins align in a parallel. It has a barely detectable 1.12% potassium radioactivity based on the GRapi unit (Gamma Ray American Petroleum Institute Units). It consists of mostly oxygen (41.98%), silicon (26.8%) and calcium (15.93%), but otherwise contains sodium (7.31%), potassium (6.22%), which gives its radioactive properties, fluorine (1.51%) and hydrogen (0.24%). There are two varieties of canasite: fluorcanasite and frankamenite. Purple canasite may be confused with stichtite, but recent research has found that the mineral advertized as canasite is a new specimen.

## Occurrences and localities

Canasite has been found in three localities, all in Russia. In Khibiny massif, it grows in a differentiated alkalic massif in pegmatites, and in the Murun massif, it grows in charoitic rocks. It also occurs in the Kola Peninsula. In Khibiny massif, it is associated with titanite, eudialyte, orthoclase, nepheline, pyroxene, lamprophyllite and fenaksite, while the specimens from Murun massif are usually associated with charoite, tinaksite and miserite.
# CAPOS syndrome

CAPOS syndrome is a rare genetic neurological disorder which is characterized by abnormalities of the feet, eyes and brain which affect their normal function. These symptoms occur episodically when a fever-related infection is present within the body. The name is an acronym for "cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss".

## Signs and symptoms

Usually, individuals with this condition have cerebellar ataxia, areflexia, high-arched feet, optic nerve wasting/degeneration, sensorineural deafness.
These symptoms have variable onset, but they generally begin episodically after having a fever-causing infection such as the common cold, manifesting mainly as sudden-onset ataxic episodes and encephalopathy. Other triggers include pregnancy and giving birth. Other symptoms that occur during the episodic ataxia includes hypotonia, nystagmus, strabismus, dysarthria, dysphagia, areflexia/hyporeflexia, and temporary deafness. More serious symptoms include loss of consciousness and/or onset of a coma.
These symptoms usually improve alongside the illness that caused the fever.
General frequency of episodes with people suffering from CAPOS syndrome is 1-3.

## Complications

There are various complications associated with the disorder, some of them include vision impairment/blindness due to optic atrophy characteristic of the disorder, deafness due to atrophy of the nerves that aid in hearing, problems with walking due to the ataxia, etc.

## Causes

This condition is caused by autosomal dominant missense mutations in the ATP1A3 gene, in chromosome 19. The mutation is thought to be gain-of-function.

## Epidemiology

According to OMIM, only 14 cases have been described in medical literature.

## History

This condition was first discovered in 1996 by Nicolaides et al. when they described a mother and two siblings (brother and sister) with (summarized) early-onset reoccurring cerebellar ataxia and progressive optic atrophy accompanied by sensorineural deafness.
# Hugh D.T. Williamson

Hugh Dean Thomas Williamson C.B.E. (1901–1985) was an Australian banking executive and philanthropist.
Williamson was born 4 February 1901 in Ballarat and died 20 December 1985 in Melbourne. He was the son of John Christopher Williamson and Jane (née Thomas) Williamson. In 1929 he married Louise Buchanan McPherson. Near the time of his retirement they began living apart. He met Elaine Berkefeld, who became his companion for the remainder of his life.
Williamson spent 44 years in banking, beginning in 1917 with the Ballarat Banking Company. He spent most of his career with the former Bank of Australasia and following the merger with ANZ rose to the position of general manager of ANZ Bank, a position he held for seven years until his retirement in June 1961. As general manager, he was responsible for eliminating the fractious attitudes following the merger, smoothing an adversarial relationship with the central bank, mechanizing back office operations, and improving branch efficiencies. He was a past president of the Australasian Institute of Banking and Finance, a predecessor of FINSIA, the Financial Services Institute of Australasia.
Post-retirement he applied the profits from his extensive investments to support his community interests, which included the Salvation Army and the trust of the Victorian Arts Centre. Through Williamson's will, the Hugh Williamson Foundation was established in 1986, and distributes more than A$1M per year. The Foundation focuses on multiple projects, including the arts the environment, scholarships and community leadership, in particular the eponymous Williamson Community Leadership Program (which later became Leadership Victoria).
