# Bony bream

Bony bream Nematalosa erebi are a widespread and common, small to medium-sized Australian freshwater fish often found in large shoals throughout much of northern and central Australia, and the Murray-Darling basin.

## Description

A deep bodied, laterally compressed fish with a blunt snout. Spineless dorsal fin with the posterior ray developed into a long filament. Usually silver overall, sometimes grey to greenish dorsally. In Victoria it has been reported to develop a rusty red tinge especially around the mouth which is thought to be related to breeding. Some populations develop a dark blotch on the shoulder.

## Distribution

Common and widespread throughout its range, found in the Pilbara, Timor Sea, Gulf of Carpentaria, Northeast Coast, Murray-Darling (at elevations below 200 metres, 650 ft) Are present in Tinaroo Dam, elevation 660m, often referred to as "Barra lollies" because of a tendency for impoundment barramundi to round them up and Lake Eyre Australian drainage divisions. Tends to forms large shoals near the bottom.

## Habitat

Variable, but mostly in shallow areas of slow flowing or still rivers and streams, especially in turbid conditions; desert bores; and, fresh or saline lakes (up to almost sea water salinity). Can tolerate water temperatures between 9° and 38 °C and a pH between 4.8 and 8.6. Despite these wide tolerances, bony bream are susceptible to low oxygen levels and are often the first species to succumb when ephemeral habitats begin to dry up.

## Diet

Primarily feeds on benthic algae but also consumes detritus and small invertebrates.
# Julius Gustaaf Arnout Koenders

Julius Gustaaf Arnout Koenders (1 March 1886 – 17 November 1957) was a Surinamese teacher and fervent activist for Sranan Tongo. As a teacher, he was forced to use the Dutch language thus denying the children their own language. He was an early advocate of Sranan and Creole culture.

## Writer

In 1943, the women's organisation Pohama asked Koenders to help them. Pohama consisted of about 20 women who wanted to strengthen the education of their children and make them proud of their own heritage. Pohama organised cultural evenings in theatre Thalia in Paramaribo, and was known for their 1 July event to remember the emancipation of slavery in Suriname. Koenders wrote his first publication for them called Foe memre wi afo [In memory of our forefathers] about the Creole language, and went to write much more for the organisation.
Even though most of his literary work consisted of translations of existing work into Sranan Tongo, Koenders was influential in inspiring the next generation like Eddy Bruma and Trefossa.
Koenders also wrote articles in Dutch about education in De schakel tussen school en huis (The bridge between school and home) using the pseudonym Kris Kras. The magazine was published every two weeks and was bundled with Dagblad Suriname.

## Foetoe-boi

Foetoe-boi was a monthly periodical he published with the association Pohama from May 1946 to April 1956, and was the editor responsible for it, though other authors were involved. It was published in both Sranan Tongo and Dutch, with many articles based on his own ideals. The cultural association Wie Eegie Sanie which was founded in 1951 by Eddy Bruma would continue Koenders' pioneering work after Foetoe-boi stopped.

# Petasites pyrenaicus

Petasites pyrenaicus, the winter heliotrope, is a medicinal and ornamental flowering plant in the family Asteraceae.

## Description

This perennial grows from deep rhizomes. The leaves are large, suborbicular and up to 20 cm across and stalked with small regular teeth. The species is dioecious, male and female flowers being borne on separate plants. The erect flower-heads grow in short racemes on stems up to 25 cm long with a few scale-leaves. The florets are pinkish-mauve and appear in December in Ireland and from January to March$^{:323}$ in Great Britain. The flowers have a vanilla-like scent. Other species to be found in Ireland and Great Britain: Petasites hybridus (L.) P.Gaertner, B. Meyer & Scherb, Petasites albus (L.) Gaertner. and Petasites japonicus (Siebold & Zucc.) Maxim.

## Distribution

Petasites pyrenaicus is native to the Mediterranean region of Europe, including Italy, Sicily, Sardinia and north Africa. It was introduced to Great Britain in 1806 where it has become naturalized. It was recorded in the wild by at least 1835 in Middlesex It is also introduced and naturalized in Ireland. Female plants are unknown in the British Isles.$^{:771}$ The male plant is grown as an ornamental in gardens and some churchyards, and was well established by the start of the 20th century.

## Ecology

Common on shady roadside banks. The underground rhizomes allow it to spread and its large leaves can shade out other plants. It is considered an invasive plant but can be controlled by cultivation or weedkiller.
# Juuso Ngaikukwete

Juuso Amuaalua (Hamalwa) Ngaikukwete (born c. 1873 in Oukwanyama, Ovamboland, Namibia — died 17 June 1955) was one of the first seven Ovambo pastors, whom the director of the Finnish Missionary Society, Matti Tarkkanen ordained into priesthood in Oniipa, Ovamboland, on 27 September 1925, with a permission granted by the Bishop of Tampere, Jaakko Gummerus.

# Izz al-Din ibn Rukn al-Din Mahmud

Izz al-Din (died September 29, 1382) was the Mihrabanid malik of Sistan from 1352 until 1380. He was the son of Rukn al-Din Mahmud.

## Biography

Izz al-Din was appointed as malik by the notables of Sistan in 1352 after the death of Jalal al-Din Mahmud. Soon after his ascension, a conflict broke out between him and his cousin Muhammad ibn Nusrat al-Din Muhammad, who was governor of the town of Uq and commanded a large degree of support in northern Sistan. Muhammad rebuilt several fortresses and seized crown lands in his locality. Civil war quickly erupted, during which the canals and agricultural fields of Sistan were damaged and famine became a serious problem. In the midst of this war 'Izz al-Din granted refuge in 1363/1364 to Timur Barlas, who had recently been expelled from Transoxiana.
In Izz al-Din's later years popular discontent began to grow against his vizier, Muhammad 'Ata'. The opposition was soon joined by Izz al-Din's son, Qutb al-Din. One day, while the malik was on a hunting trip, a Shahr-i Sistan mob overran the citadel and killed the vizier. Qutb al-Din and his supporters then battled Izz al-Din's forces and defeated them. The malik was captured and exiled.
Izz al-Din, intent on recovering his throne, made his way to Herat and gained the support of the Kartid malik Giyath al-Din Pir 'Ali. Together with the malik of Farah, Iksandar ibn Inaltigin, Izz al-Din and a Kartid force invaded Sistan in the spring of 1380. Qutb al-Din, seeing many of his supporters abandon him, decided to flee, enabling Izz al-Din to retake Shahr-i Sistan. Qutb al-Din, however, was invited by several nobles and military commanders to return; upon doing so he defeated Izz al-Din and Iksandar and forced them to leave Sistan. At this point Izz al-Din's desire to maintain his rule weakened; he returned to Sistan and renounced the throne in favor of his son. He died two years later, in 1382.

# Boué–Dupuis formula

In stochastic calculus, the Boué–Dupuis formula is variational representation for Wiener functionals. The representation has application in finding large deviation asymptotics.
The theorem was proven in 1998 by Michelle Boué and Paul Dupuis. In 2000 the result was generalized to infinite-dimensional Brownian motions and in 2009 extended to abstract Wiener spaces.

## Boué–Dupuis formula

Let $C([0,1],\mathbb {R} ^{d})$ be the classical Wiener space and $B$ be a $d$-dimensional standard Brownian motion. Then for all bounded and measurable functions $f:C([0,1],\mathbb {R} ^{d})\to \mathbb {R}$ we have the following variational representation
    $-\log \mathbb {E} \left[e^{-f(B)}\right]=\inf \limits _{V}\mathbb {E} \left[{\frac {1}{2}}\int _{0}^{1}\|V_{t}\|^{2}\mathrm {d} t+f\left(B+\int _{0}^{\cdot }V_{t}\mathrm {d} t\right)\right],$
where:
* The expectation is with respect to the probability space of $B$.
* The infimum runs over all processes which are progressively measurable with respect to the augmented filtration ${\mathcal {F}}^{B}$ generated by $B$
* $\|\cdot \|$ denotes the $d$-dimensional Euclidean norm.
# Ponte di Quintodecimo

# Paddy Walker House

The Paddy Walker House (also known as the Walker House) is the town of Kincardine's oldest building and the oldest standing hotel in Bruce County, Ontario, Canada.

## History

In 1850, Francis "Paddy" Walker travelled across the frozen Lake Huron from Goderich, Ontario to the 2 year old settlement of Penetangore (Kincardine, Ontario). Mr. Walker arrived in the settlement with his wife Jane and his seven sons. Realizing that when new settlers like himself arrived to Penetangore they would need somewhere to stay, Paddy Walker soon built a Hotel situated near the mouth of the Penetangore (later the Harbour).
The Walker House served as a hotel under the management of Paddy Walker and his descendants until 1942 when the Walker house was sold to Marie and Al Gairns. The Walker house was still used as a hotel under the ownership of Mr. and Mrs. Gairns until they decided to turn it into a rooming house. After the death of Mr. Gairns, Marie Gairns used the Walker House as her own private home well into the 1990s.

## Fire and revitalization

In January 1995, a fire broke out in the Walker House and Marie Gairns had to be rescued from the Walker House in her chair by local fireman.
The building was severely damaged and wasn't touched for three years and left to suffer from the natural elements. A rumor was spread that the Municipality of Kincardine was going to demolish the Walker house. The locals felt that that action would have too many negative results. As a result, the Paddy Walker Heritage Society was created, and the society bought the Walker House from Mrs. Gairns in 1998. Many restorations were done to the Walker House and the construction was completed in 2008 in time for the 2008 Kincardine Old Boys Reunion.

## The Walker House Today

The Walker House serves Kincardine and the surrounding region as a heritage centre, providing exhibits, programmes and hosting events that interpret local history.
The Walker House Heritage society is a meeting room for the Kincardine Heritage Society, as well as a local museum. It is closed during the winter months but open during the summer months as Kincardine's main industry is tourism.

# Pentaerythritol tetraacrylate

Pentaerythritol tetraacrylate (PETA, sometimes PETTA, PETRA) is an organic compound. It is a tetrafunctional acrylate ester used as a monomer in the manufacture of polymers. As it is a polymerizable acrylate monomer, it is nearly always supplied with an added polymerisation inhibitor, such as MEHQ (monomethyl ether hydroquinone).

## Uses

PETA is part of a family of acrylates used in epoxy resin chemistry and ultraviolet cure of coatings. Similar monomers used are 1,6-hexanediol diacrylate and trimethylol propane triacrylate. It is a derivative of pentaerythritol One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers.
The molecule's acrylate group functionality enables the molecule to do the Michael reaction with amines. It is therefore sometimes used in epoxy chemistry enabling a large reduction in cure time. As the molecule has 4 functional acrylate groups it confers high cross-link density. Ethoxylation maybe used to produce ethoxylated versions which find use in electron beam curing. The material also has pharmaceutical uses
