Metellina mengei is a spider of the family Tetragnathidae that is found in Europe up to Georgia. It was once considered a form of M. segmentata that occurs in spring. M. mengei is much rarer than M. segmentata. [1]
Metellina. mengei is very similar to Metellina segmentata , from which it can only be discerned by comparing genital features. It is about 5 mm long. Adults are found from May to July. [1]
The lorica segmentata, also called lorica lamminata, is a type of personal armour that was used by soldiers of the Roman Empire, consisting of metal strips fashioned into circular bands, fastened to internal leather straps. The lorica segmentata has come to be viewed as iconic of the Roman legions in popular culture. The tendency to portray Roman legionaries clad in this type of armour often extends to periods of time that are too early or too late in history.
The Soyuz programme is a human spaceflight programme initiated by the Soviet Union in the early 1960s. The Soyuz spacecraft was originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok and Voskhod programmes.
Kosmos is a designation given to many satellites operated by the Soviet Union and subsequently Russia. Kosmos 1, the first spacecraft to be given a Kosmos designation, was launched on 16 March 1962.
The Kosmos-3M is a Russian space launch vehicle, member of the Kosmos. It is a liquid-fueled two-stage rocket, first launched in 1967 and with over 420 successful launches to its name. The Kosmos-3M uses UDMH fuel and AK27I oxidizer to lift roughly 1,400 kg (3,100 lb) of payload into orbit. It differed from the earlier Kosmos-3 in its finer control of the second-stage burn, allowing operators to tune the thrust and even channel it through nozzles that helped orient the rocket for the launching of multiple satellites at one time. PO Polyot has manufactured these launch vehicles in the Russian town of Omsk for decades. It was originally scheduled to be retired from service in 2011; however, in April 2010 the Commander of the Russian Space Forces confirmed that it would be retired by the end of 2010. One further launch, with Kanopus-ST, was planned; however, this was cancelled in late 2012 as the rocket had exceeded its design life while in storage ahead of the launch.
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) is a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water.
The Kosmos rockets were a series of Soviet and subsequently Russian rockets, derived from the R-12 and R-14 missiles, the best known of which is the Kosmos-3M, which has made over 440 launches. The Kosmos family contained a number of rockets, both carrier rockets and sounding rockets, for orbital and sub-orbital spaceflight respectively. The first variant, the Kosmos-2I, first flew on 27 October 1961. Over 700 Kosmos rockets have been launched overall.
A manica was a type of iron or bronze arm guard, with curved and overlapping metal segments or plates, fastened to leather straps, worn by Roman gladiators called crupellarii, and later optionally by soldiers.
The Bion satellites, also named Biocosmos, is a series of Soviet biosatellites focused on space medicine. They are part of the Kosmos satellites.
Roman military personal equipment was produced in small numbers to established patterns, and it was used in an established manner. These standard patterns and uses were called the res militaris or disciplina. Its regular practice during the Roman Republic and Roman Empire led to military excellence and victory. The equipment gave the Romans a very distinct advantage over their barbarian enemies, especially so in the case of armour. This does not mean that every Roman soldier had better equipment than the richer men among his opponents. According to Edward Luttwak, Roman equipment was not of a better quality than that used by the majority of Rome's adversaries. Other historians and writers have stated that the Roman army's need for large quantities of "mass produced" equipment after the Marian Reforms and subsequent civil wars led to a decline in the quality of Roman equipment compared to the earlier Republican era:
"The production of these kinds of helmets of Italic tradition decreased in quality because of the demands of equipping huge armies, especially during civil wars...The bad quality of these helmets is recorded by the sources describing how sometimes they were covered by wicker protections, like those of Pompeius' soldiers during the siege of Dyrrachium in 48 BC, which were seriously damaged by the missiles of Caesar's slingers and archers."
"It would appear that armour quality suffered at times when mass production methods were being used to meet the increased demand ..." and "...the reduced size curiasses would also have been quicker and cheaper to produce, which may have been a deciding factor at times of financial crisis, or where large bodies of men were required to be mobilized at short notice, possibly reflected in the poor-quality, mass produced iron helmets of Imperial Italic type C, as found, for example, in the River Po at Cremona, associated with the Civil Wars of AD 69 AD; Russel-Robinson, 1975, 67"
"Up until then, the quality of helmets had been fairly consistent and the bowls well decorated and finished. However, after the Marian Reforms, with their resultant influx of the poorest citizens into the army, there must inevitably have been a massive demand for cheaper equipment, a situation which can only have been exacerbated by the Civil Wars..."
Metellina is a genus of tetragnathid spiders that occurs mostly in Eurasia, with two species found in North America. M. segmentata was introduced to Canada.
Metellina segmentata is a spider in the family Tetragnathidae with a Palaearctic distribution. This spiders name is often shortened to Meta segmentata,and some even call it Araneus segmentatus simply meaning, orb weaving spiders. It is primarily found in Europe, with the highest number in the United Kingdom, but the species has also been introduced to Canada.
The Kosmos-3 was a Soviet carrier rocket, derived from the R-14 missile, which was used to orbit satellites between 1966 and 1968. It was quickly replaced by the modernised Kosmos-3M. Six were flown, four as orbital carrier rockets, and two on sub-orbital flights. All launches occurred from Site 41/15 at the Baikonur Cosmodrome.
Dnepropetrovsk Sputnik, also known as DS, was a series of satellites launched by the Soviet Union between 1961 and 1982. DS satellites were used for a number of missions, including technological and scientific research, and radar tracking targets for anti-satellite weapons and anti-ballistic missiles. 185 were launched, using dedicated Kosmos rockets.·
Kosmos 459, also known as DS-P1-M No.5 was a satellite which was used as a target for tests of anti-satellite weapons. It was launched by the Soviet Union in 1971 as part of the Dnepropetrovsk Sputnik programme, and used as a target for Kosmos 462, as part of the Istrebitel Sputnikov programme.
Kosmos 1241 was a target satellite which was used by the Soviet Union in the 1980s for tests of anti-satellite weapons as part of the Istrebitel Sputnikov programme. It was launched in 1981, and was itself part of the Dnepropetrovsk Sputnik programme. It was a target for Kosmos 1243 and Kosmos 1258.
Kosmos 97, also known as DS-U2-M No.1, was a Soviet satellite which was launched in 1965 as part of the Dnepropetrovsk Sputnik programme. It was a 267 kilograms (589 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and used to conduct tests involving atomic clocks.
Metellina merianae is a spider species found in Europe up to Georgia.
Apolania is a monotypic genus of East African wandering spiders containing the single species, Apolania segmentata, first described from a male found by Eugène Simon in 1898. No females have been described yet, and it has only been found in Seychelles.
Metellina curtisi is a species of long-jawed orb weaver in the spider family Tetragnathidae. It is found in North America.
Metellina mimetoides is a species of long-jawed orb weaver in the spider family Tetragnathidae. It is found in North America.
