# Hélio Ferraz de Almeida Camargo

Hélio Ferraz de Almeida Camargo (6 June 1922 – 14 July 2006) was a Brazilian zoologist and lawyer, who primarily worked with Brazilian birds.

## Life

Camargo was born in the city of Piracicaba, São Paulo, in 1922, son of Theodureto Leite de Almeida Camargo and Davina Ferraz de Almeida Camargo. He studied Law in the University of São Paulo, graduating in 1952. However, he was deeply interested in zoology and began working in 1944 as a trainee in the Zoology Department of Secretaria da Agricultura do Estado de São Paulo – which in 1969 became the Museum of Zoology of the University of São Paulo, being effectivated as biologist in 1946. Camargo started working with Dr. Olivério Pinto, taking the administration of the bird section of the museum after his retirement. From 1966 to 1979, he was substitute director of the museum, until retiring in 1980, but continued working as the curator of the bird section until 2001.
The bulk of his work was with Brazilian birds diversity, going to field to collect specimens for the museum in various biomes of the country and publishing the results of his observations. In 1989 he described, with Rolf Grantsau, the new amazon species Amazona kawalli. He also worked in the fish section of the museum and during the 1950s he studied spiders, even naming three new Brazilian species: Parawixia inopinata Camargo, 1951, Wagneriana gavensis (Camargo, 1951) and Tetragnatha soaresi, which he synonymized as junior synonym of T. longidens Mello-Leitão, 1945, in 1953.
In recognition of his work in ornithology, the hummingbird Phaethornis ochraceiventris camargoi Grantsau, 1988 and the furnarid Heliobletus contaminatus camargoi Silva & Stotz, 1992 were named after him.

## History

Rugby in the then Czechoslovakia was much affected following the nationwide restructuring of Physical Education and Sport in 1953. The Sokol Zbrojovka Brno club split in two, Spartak Zbrojovka Brno (now Dragon Brno) and Slavia VŠ Brno.
The club played in the Řečkovice, Pisárky, Tuřany, and Kníničky areas of Brno as well as the town of Šlapanice and the village of Troubsko, before finally managing to secure their present home ground, the Sportovní areá Ondreje Sekory, at Bystrc.

# Pão por Deus

Pão-por-Deus (Portuguese pronunciation:, "Bread for God") is the Portuguese tradition of souling celebrated all over Portugal, named for the soulmass-cakes given to the poor on All Saints' Day, typically by children and youth. Names for the custom vary through different regions of the country, for instance, around Leiria it is known as "Dia do Bolinho" ("Cookie Day").

## Origins

There are records of the day of Pão-de-Deus in the 15th century. On 1 November 1755 in Lisbon, after the vast majority of the city's residents lost everything to the Great Lisbon earthquake the survivors had to ask for this bread in the neighbouring towns.

## Customs

From early in the morning (8 or 9 am) children meet together and walk around the neighborhood, knock at all doors and local stores and say "Pão-por-Deus" to the adults they meet.
People at home give them small gifts such as broas (small bread-like cakes flavored heavily with anise and nuts), chocolates, candy, nuts, fruit, or in some cases, money.
At the local stores, the offers are different. A store may give the children treats or a sample of a product they sell: bakers give a little bread, fruit stalls give some chestnuts, and so on.
In the Azores, the children are given a cake called "caspiada" during this ritual begging. The cakes have the shape of the top of a skull.
The Pão-de-Deus or Santoro is the bread, or offering, that is given to the dead, the Molete or Samagaio (also called sabatina, raiva da criança (child's rage)) is the bread, or offering, that is given when a child is born.
# Ion Atanasiu

Ion A. Atanasiu (25 September 1894 – 19 December 1978) was the founder of the Romanian School of Electrochemistry and the first to teach this subject in Romania. He is known as the originator of cerimetry, an analytical method based on Cerium (IV) as titration reagent.
Born in Iași, Atanasiu became a professor of geology at the University of Iași and later at the University of Bucharest. He was elected corresponding member of the Romanian Academy in 1940. His father, Sava Athanasiu, a geologist and paleontologist, became a honorary member of the Academy in 1945, while his brother, Gheorghe Atanasiu [ro], a physicist, became a titular member in 1963.

# Pen (livestock farm)

A pen was a livestock farm on the Island of Jamaica. Pen-keeping included the breeding of cattle, horses, mules, sheep and dairy farming. Gardner (1873), referring to the 1750s, stated: "The life of a tolerably successful pen-keeper was at this period, as it is now, the most enviable to be found in the colony. Cattle thrive well, and few servants are required when once a pen is well established."
Batchelors Hall Pen was owned by Chaloner Arcedekne; it supplied Golden Grove Plantation, owned by the prominent Simon Taylor. Correspondence between the two men survives.

# Prionosciadium saraviki

Prionosciadium saraviki, common name saraviki, is a plant species in the genus Prionosciadium, in the carrot family, Apiaceae. It is known only from a mountainous region of the Sierra Madre Occidental in the Mexican State of Chihuahua. Type locale is the village of Nabogame, approximately 18 km northwest of Yepachic, Chihuahua, 10 km east of the border with Sonora. The plant grows there mostly along creekbanks and near springs.
Prionosciadium saraviki is a biennial producing a flowering stalk up to 2 m (7 feet) tall. It bears a compound umbel with hundreds of small yellow flowers. The taproot is up to 3 cm in diameter, white with a papery, copper-colored skin.
A few sources (e.g. The Plant List) have misspelled the epithet as "saravikii." This is an error because the epithet is the native name for the species, not honoring a person.

## Uses

The epithet "saraviki" is the local name for the plant as used by the Pima Bajo (= Mountain Pima) peoples of the region in which the plant is found. They sometimes eat the edible taproots. The roots and shoots have a pleasing aromatic scent.
# R Sagittae

R Sagittae is an RV Tauri variable star in the constellation Sagitta that varies from magnitude 8.0 to 10.5 in 70.77 days. It is a post-AGB low mass yellow supergiant that varies between spectral types G0Ib and G8Ib as it pulsates. Its variable star designation of "R" indicates that it was the first star discovered to be variable in the constellation. It was discovered in 1859 by Joseph Baxendell, though classified as a semi regular variable until RV Tauri variables were identified as a distinct class in 1905.
R Sagittae is classified as an RV Tauri variable because of the distinctive regular variations with alternating deep and shallow minima. The period is conventionally quoted as the time between two deep minima and is the fundamental pulsation mode. The shallow minimum is the result of a first overtone pulsation. It is further classified as RVb since the average and maximum magnitude varies slowly over several years. The main period also varies over a period of decades. It has around 90% the mass of the Sun and an average effective (surface) temperature of around 5000 K. It is around 10,000 times as luminous as the Sun. Measurement of its parallax by the Gaia satellite yields a distance of around 8,100 light-years.
Variable star observer David Levy recommends that amateur observers monitor it once a week to observe changes in brightness.
RV Tauri variables are post-AGB stars, originally similar to the Sun but now in the last stages of their lives. They are crossing the Cepheid instability strip as they lose their outer layers on the way to becoming a planetary nebula. Although their spectra and luminosities resemble supergiants, they are old low mass population II stars. A period-colour-luminosity relationship has been derived from observations of RV Tauri variables in the Large Magellanic Cloud that is closely related to the relationship for type II Cepheid variables.
