Sas coat of arms

Sas or Szász (origin: Slavic for "Saxon," Polish: Sas, Hungarian: Szász, Romanian: Saş) is a Central European coat of arms. It was borne since the medieval period by several Transylvanian-Saxon Hungarian nobility, Ruthenian nobility and Polish-Lithuanian szlachta families. The house was once a mighty princely and ducal house with origins in Saxony, Transylvania, Hungary and Ruthenia.

History

Ancient Polish-Lithuanian historians like Szymon Okolski say that the origin of these arms is derived from Saxony, where during the mid-12th century King Géza II of Hungary invited Germanic peoples of Saxony to settle in, establish trading centres and defend relatively sparsely populated Transylvania in the Kingdom of Hungary, upon which the Transylvanian Saxons were later given a privileged status in the "Diploma Andreanum" (Golden Charter of Transylvanian Saxons) issued by King Andrew II of Hungary (see Transylvanian Saxons).

The origins of the dynastic House of Sas or Szász vary depending on the source. According to the chronicles of Albertus Strepa; the outstanding military leader Comes Huyd of Hungary (a Transylvanian-Saxon), entered Galicia in 1236 with his mighty army of allied mounted warrior knights to the service of Daniel of Galicia King of Ruthenia, and each was rewarded with lands in Red Ruthenia that Huyd and his allied noble knights settled, being referred to as the Sas/Szász (Saxon) due to their Transylvanian Saxon dialect and origin.

Small Astronomy Satellite 2

The Small Astronomy Satellite 2, also known also as SAS-2, SAS B or Explorer 48, was a NASA gamma ray telescope. It was launched on 15 November 1972 into the low Earth orbit with a periapsis of 443 km and an apoapsis of 632 km. It completed its observations on 8 June 1973.

SAS 2 was the second in the series of small spacecraft designed to extend the astronomical studies in the X-ray, gamma-ray, ultraviolet, visible, and infrared regions. The primary objective of the SAS-B was to measure the spatial and energy distribution of primary galactic and extragalactic gamma radiation which energies between 20 and 300 MeV. The instrumentation consisted principally of a guard scintillation detector, an upper and a lower spark chamber, and a charged particle telescope.

SAS-2 was launched from the San Marco platform off the coast of Kenya, Africa, into a nearly equatorial orbit. The orbiting spacecraft was in the shape of a cylinder approximately 59 cm in diameter and 135 cm in length. Four solar paddles were used to recharge the 6 amp-h nickel-cadmium battery and provide power to the spacecraft and telescope experiment. The spacecraft was spin stabilized, and a magnetically torqued commandable control system was used to point the spin axis of the spacecraft to any position in space within approximately 1 degree. The experiment axis lay along this axis allowing the telescope to look at any selected region of the sky with its plus or minus 30 degree acceptance aperture. The nominal spin rate was 1/12 rpm. Data were taken at 1000 bit/s and could be recorded on an onboard tape recorder and simultaneously transmitted in real time. The recorded data were transmitted once per orbit. This required approximately 5 minutes.

Small Astronomy Satellite 3

The Small Astronomy Satellite 3 (SAS 3, also known as SAS-C before launch) was a NASA X-ray astronomy space telescope. It functioned from May 7, 1975 to April 1979. It covered the X-ray range with four experiments on board. The satellite, built by the Johns Hopkins University Applied Physics Laboratory (APL), was proposed and operated by MIT's Center for Space Research (CSR). It was launched on a Scout vehicle from the Italian San Marco launch platform near Mombasa, Kenya, into a low-Earth, nearly equatorial orbit. It was also known as Explorer 53, as part of NASA's Explorer program.

The spacecraft was 3-axis stabilized with a momentum wheel that was used to establish stability about the nominal rotation, or z-axis. The orientation of the z-axis could be altered over a period of hours using magnetic torque coils that interacted with the Earth's magnetic field. Solar panels charged batteries during the daylight portion of each orbit, so that SAS 3 had essentially no expendables to limit its lifetime beyond the life of the tape recorders, batteries, and orbital drag. The spacecraft typically operated in a rotating mode, spinning at one revolution per 95-min orbit, so that the LEDs, tube and slat collimator experiments, which looked out along the y-axis, could view and scan the sky almost continuously. The rotation could also be stopped, allowing extended (up to 30 min) pointed observations of selected sources by the y-axis instruments. Data were recorded on board by magnetic tape recorders, and played back during station passes every orbit.

Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.

1994 Group

The 1994 Group was a coalition of smaller research-intensive universities in the United Kingdom, founded in 1994 to defend these universities' interests following the creation of the Russell Group by larger research-intensive universities earlier that year. The 1994 Group originally represented seventeen universities, rising to nineteen, and then dropping to eleven. The Group started to falter in 2012, when a number of high performing members left to join the Russell Group. The 1994 Group ultimately dissolved in November 2013.

Role

The group sought "to represent the views of its members on the current state and the future of higher education through discussions with the government, funding bodies, and other higher education interest groups" and "[made] its views known through its research publications and in the media".

University Alliance, million+, GuildHE and the Russell Group were its fellow university membership groups across the UK higher education sector.
