# Acacia nigripilosa

Acacia nigripilosa is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to Western Australia.

## Description

The shrub typically grows to a height of 0.5 to 2 metres (1.6 to 6.6 ft). It has glabrous ash-grey, coloured branchlets. the ascending to erect dull to shiny green phyllodes have a linear to narrowly oblong-elliptic or oblanceolate shape. The phyllodes have a length of 2 to 7 cm (0.79 to 2.76 in) and a width of 1 to 8 mm (0.039 to 0.315 in) and are narrowed at the base. It blooms from July to September and produces yellow flowers. The inflorescences occur singly or in pairs along an axes of 1 to 3 mm (0.039 to 0.118 in). The flower-heads have a slightly obloid shape and contain 18 to 34 golden flowers. The seed pods that form after flowering resemble a string of beads and have a length of 4 to 9 cm (1.6 to 3.5 in) and a width of 4 to 7 mm (0.16 to 0.28 in). the shiny dark brown seeds within the pods have an oblong-elliptic to ovate shape and a length of around 4 mm (0.16 in).

## Taxonomy

The species was first formally described by the botanist Joseph Maiden in 1920 as part of the work Notes on Acacias, No. IV, with descriptions of new species as published in the Journal and Proceedings of the Royal Society of New South Wales. It was reclassified in 2003 as Racosperma nigripilosum by Leslie Pedley then transferred back to the genus Acacia in 2006. The only other synonym for this species is Acacia nigripilosus.
There are two recognized subspecies:
* Acacia nigripilosa subsp. latifolia
* Acacia nigripilosa subsp. nigripilosa

## Distribution

It is native to an area in the Mid West, Goldfields and Wheatbelt regions of Western Australia where it grows in sandy soils around laterite. It is found as far north as around Yuna south to around Goomalling and east out to Mount Holland where it is found in scrubland or open woodland communities.

# Iść w stronę słońca

"Iść w stronę słońca" is a 1981 song by Polish band 2 Plus 1.

## Song information

The song was composed by the band's leader Janusz Kruk, and the lyrics were written by Andrzej Mogielnicki, a popular Polish lyricist. It was first released on a cardboard record by Tonpress in 1981, a popular medium often replacing the single format in the pre-1990s Poland. In the same year, the track appeared on a various artists EP VIII konkurs na piosenkę dla młodzieży, which also included songs by such popular Polish acts as Izabela Trojanowska and Kombi.

# Inverted binocular phenomenon

Disowning Pain Phenomenon (or "Inverted binocular phenomena") is the subject of a 2008 study which suggested that distorting the body image can change the way people sense how it feels. For example, when a person sees an organ through inverted binoculars, it looks smaller than it really is, which may reduce the pain connected to that organ.
Ten patients with persistent discomfort in their right arms that was exacerbated by movement were instructed to move their arms while their visual impressions of those arms were adjusted. They first used binoculars to magnify how their bodies appeared, then switched to inverted binoculars to lessen the size of the image. They were also asked to rate the level of pain they felt while viewing the image. The more limbs that developed, the greater pain was felt. Binocular magnifying and minimizing can even modify the extent of edema.

# Active Wheel

Active Wheel was a Michelin-developed tire which incorporates an electric motor and suspension It was presented at Challenge Bibendum 2004's edition on the Hy-Light concept car and showcased during Paris Motor Show "Mondial de l'automobile"in 2008 both on the Venturi Volage electric sports car and on the Heuliez Will. The project was interrupted in 2014.
Like other in-wheel motors, the ActiveWheel design provides direct power delivery of approximately 30 kW (40 hp), as well as regenerative braking. In addition, it replaces a mechanical suspension with an active suspension driven by an in-wheel electrical suspension motor that controls torque distribution, traction, turning maneuvers, pitch, roll and suspension damping for that wheel. However, the effects of shocks, water and snow to such an "in-wheel" design have not been precisely studied.
Siemens VDO, developing a similar concept called eCorner, was purchased by Continental in 2007.
# 21 Vulpeculae

21 Vulpeculae is a single, white-hued star in the northern constellation of Vulpecula. Its distance can be estimated from the annual parallax shift of 10.4302±0.0696 mas, yielding a separation of 313 light years. The star is faintly visible to the naked eye at night, having an apparent visual magnitude of 5.19. It is moving further away with a heliocentric radial velocity of about +7 km/s, having come within 243 ly (74.53 pc) around 4.2 million years ago.
There is some disagreement about the class of this star. Cowley et al. (1969) listed it as an A-type subgiant star with a stellar classification of A7 IVn, where the 'n' notation indicates "nebulous" lines due to rapid rotation. The luminosity class of IV suggests the star has exhausted the supply of hydrogen at its core and is evolving away from the main sequence. Slettebak (1982) classified it as an A5 IV shell star and it was so regarded by Hauck & Jaschek (2000), while Abt & Morrell (1995) listed it with a class of A5 Vn, indicating a rapidly-rotating A-type main-sequence star. It is a Delta Scuti type variable star, with a dominant pulsation period of 0.1881 days and an amplitude of 0.016 in magnitude.
David and Hillenbrand (2015) found an average mass for this star of 1.61 times the mass of the Sun, whereas Zorec and Royer (2012) list a much higher mass estimate of 2.36±0.03 M$_☉$. It is about 356 million years old with a projected rotational velocity of 222 km/s. This rapid rotation is giving the star an oblate shape with an equatorial bulge that is an estimated 16% larger than the polar radius. Observations since 1997 suggest 21 Vul has an orbiting disk of gaseous material that is too equatorially confined to make it a shell star. The line strengths from this disk have been decreasing over time.
