Tetraphenyldiphosphine
Tetraphenyldiphosphine is the organophosphorus compound with the formula [PPh2]2, where Ph = phenyl (C6H5).  It is a white, air-sensitive solid that dissolves in nonpolar solvents.  It is a centrosymmetric molecule with a P-P bond of 2.2592 Å.

Tetraphenyldiphosphine  is produced by reductive coupling of chlorodiphenylphosphine...

2 Ph2PCl  +  2 Na  →   Ph2P-PPh2  +  2 NaCl

...or dehydrogenation of diphenylphosphine catalyzed by bis(triphenylphospine)nickel(II) bromide:

2 Ph2PH → Ph2P-PPh2 + H2

The compound is used as a source of the Ph2P− group.

Ph2P-PPh2  +  2 Na  →     +  2 NaPPh2

Alternatively, the compound can homolyze along the weak P–P bond, in which case the resulting radicals add to alkenes and alkynes.

Oxidation with oxygen or sulfur gives the corresponding diphosphine dioxide or disulfide.

Phenyl group
In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5−, and is often represented by the pseudoelement symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen atom, which may be replaced by some other element or compound to serve as a functional group. A phenyl group has six carbon atoms bonded together in a hexagonal planar ring, five of which are bonded to individual hydrogen atoms, with the remaining carbon bonded to a substituent. Phenyl groups are commonplace in organic chemistry. Although often depicted with alternating double and single bonds, the phenyl group is chemically aromatic and has equal bond lengths between carbon atoms in the ring.
Welsh Marches
The Welsh Marches (Welsh: Y Mers) is an imprecisely defined area along the border between England and Wales in the United Kingdom.  The precise meaning of the term has varied at different periods.

The English term Welsh March (Medieval Latin: Marchia Walliae) was originally used in the Middle Ages to denote the marches between England and the Principality of Wales, in which Marcher lords had specific rights, exercised to some extent independently of the king of England.  In modern usage, "the Marches" is often used to describe those English counties which lie along the border with Wales, particularly Shropshire and Herefordshire, and sometimes adjoining areas of Wales. However, at one time the Marches included all of the historic counties of Cheshire, Shropshire, Herefordshire, Worcestershire and Gloucestershire.

The project was funded by Team Encounter, a Texas-based startup, which went out of business in 2004.

Both transmissions were at ~150 kW, 5.01 GHz (FSK +/-24 kHz).
The Anchorage (Marietta, Ohio)
The Anchorage is a historical home in the Harmar neighborhood of Marietta, Ohio, United States.  Also known as the Putnam Villa, it was built in 1859 by Douglas Putnam for his wife Eliza.  Douglas was the great grandson of General Israel Putnam.  Douglas' brother, David Putnam, Jr. was the leading abolitionist in Marietta.  David was said to frequent the home, leading to the belief the home was used as part of the Underground Railroad although no evidence has been uncovered.

In 1894, the Knox family bought the house from the Putnams.  The Knox family was involved in boat building and gave the home the name of The Anchorage.  From 1960 to 1986 the house was a nursing home.  Since 1996, the home has been owned by the Washington County Historical Society.

Harmar, Marietta
Harmar is a historic neighborhood in the city of Marietta, Ohio, United States.

Zillergründl Dam
The Zillergründl Dam is an arch dam on the Ziller River in the upper Ziller Valley of Tyrol state, Austria. It lies 16 km (10 mi) east of Mayrhofen. The primary purpose of the dam is hydroelectric power generation and it supports a 360 MW pumped-storage power station. As part of the Zemm-Ziller Development, construction on the dam began in 1981 and, along with the Häusling Pumped Storage Power Plant, it was completed in 1986. The power plant was fully commissioned by 1988. The dam is the second tallest in Austria.

Arch dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas.

Latrodectism
Latrodectism (/lætrəˈdɛktɪzəm/) is the illness caused by the bite of Latrodectus spiders (the black widow spider and related species). Pain, muscle rigidity, vomiting, and sweating are the symptoms of latrodectism.

There are several spider species all named black widow: southern black widow spider (L. mactans), the European black widow (L. tredecimguttatus), Western black widow spider (L. hesperus), Northern black widow spider (L. variolus). Other Latrodectus that cause latrodectism are the Australian redback spider (L. hasselti), the New Zealand katipō spider (L. katipo) and the South American Latrodectus corallinus and Latrodectus curacaviensis. Several other members of the genus Latrodectus are not commonly associated with latrodectism, including the cosmopolitan brown widow (L. geometricus).

Latrodectus tredecimguttatus
Latrodectus tredecimguttatus, also known as the Mediterranean black widow or the European black widow, is a species in the genus Latrodectus of the widow spiders. It is commonly found throughout the Mediterranean region and central Asia, hence the name. Specimens from central Asia are also known by the binomial name Latrodectus lugubris; that name, however, is now considered improper, though it is still commonly found in the literature. Latrodectus tredecimguttatus was previously considered a subspecies of Latrodectus mactans.

Commodore DOS
Commodore DOS, also known as CBM DOS, is the disk operating system used with Commodore's 8-bit computers. Unlike most other DOSes, which are loaded from disk into the computer's own RAM and executed there, CBM DOS is executed internally in the drive: the DOS resides in ROM chips inside the drive, and is run there by one or more dedicated MOS 6502 family CPUs. Thus, data transfer between Commodore 8-bit computers and their disk drives more closely resembles a local area network connection than typical disk/host transfers.

Commodore 8050
The Commodore 8050, Commodore 8250, and Commodore SFD-1001 are 5¼-inch floppy disk drives manufactured by Commodore International, primarily for its 8-bit CBM and PET series of computers. The drives offered improved storage capacities over previous Commodore drive models.

They are notable for the disk drive having twice the processing power than the connected computer in having two 1MHz 6502 processors sharing operation of communication and disk operation, though only supporting 4k of main memory. The disk operating system is actually contained within the disk drive unit with commands being sent via the 8 bit GPIB interface where the system decodes the message and carries out the requested operation such as formatting a disk without further involvement from the connected computer.

21 Lyncis
21 Lyncis is a single star in the northern constellation of Lynx. It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.61. The star is located at a distance of about 274 light years away from the Sun, based on parallax. It is moving further away from the Earth with a heliocentric radial velocity of around +27 km/s.

This object is an ordinary A-type main-sequence star with a stellar classification of A0.5Vs, where the 's' suffix indicates "sharp" lines in the spectrum, usually due to slow rotation. It is about 272 million years old with a projected rotational velocity of 18 km/s. The star has 2.22 times the mass of the Sun and is radiating 102 times the luminosity of the Sun from its photosphere at an effective temperature of 9,692 K.

A-type main-sequence star
An A-type main-sequence star is a main-sequence (core hydrogen burning) star of spectral type A. The spectral luminosity class is V. These stars have spectra defined by strong hydrogen Balmer absorption lines. They measure between 1.7 and 2.1 solar masses (M☉), have surface temperatures between 7,600 and 10,000 K, and live for about a quarter of the lifetime of the Sun. Bright and nearby examples are Altair (A7), Sirius A (A1), and Vega (A0). A-type stars do not have convective zones and thus are not expected to harbor magnetic dynamos. As a consequence, because they do not have strong stellar winds; they lack a means to generate X-ray emission.
