Plutonium (centipede)
''Plutonium zwierleini'', in the Monotypic taxon, monotypic genus ''Plutonium'', is one of the largest scolopendromorph centipedes in Europe, and one of the few potentially harmful to humans. Nevertheless, it has been rarely reported, only from the southern part of the Iberian Peninsula, Iberian and Italian Peninsula, Italian peninsulas, Sardinia and Sicily. Morphology The body is mainly brown-orange, slightly darker on the head and the most posterior part of the body, including the ultimate pair of appendages. Conversely, the antennae and the walking legs are paler. The body length may surpasses 12 cm, which is the maximum measured from the anterior margin of the head to the posterior tip of the trunk, among the few specimens collected. Even higher measures have been reported in the past. ''P. zwierleini'' is fully blind, without trace of eyes. As in all other centipedes, the first appendages of the trunk are a pair of piercing fangs, which are used to grasp and poison pr ...

Plutonium Zwierleini - Trecastagni - 2 - Lucio Bonato
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoricity, pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a Deuterium, deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which subsequently Beta decay, beta-decayed to form the new element with atomic number 94 and atomic weight 238 ( ...

Scolopendromorpha
The centipedes or Chilopoda are divided into the following orders. Scutigeromorpha The Scutigeromorpha are anamorphic, reaching 15 leg-bearing segments in length. Also known as house centipedes, they are very fast creatures, and able to withstand falling at great speed: they reach up to 15 body lengths per second when dropped, surviving the fall. They are the only centipede group to retain their original compound eyes, within which a crystalline layer analogous to that seen in chelicerates and insects can be observed. They also bear long and multi-segmented antennae. Adaptation to a burrowing lifestyle has led to the degeneration of compound eyes in other orders; this feature is of great use in phylogenetic analysis. The group is the sole extant representative of the Notostigmophora, defined by having a single spiracle opening at the posterior of each dorsal plate. The more derived groups bear a plurality of spiracular openings on their sides, and are termed the Pleurostigmoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sorrento
Sorrento (, ; nap, Surriento ; la, Surrentum) is a town overlooking the Bay of Naples in Southern Italy. A popular tourist destination, Sorrento is located on the Sorrentine Peninsula at the south-eastern terminus of the Circumvesuviana rail line, within easy access from Naples and Pompei. The town is widely known for its small ceramics, lacework and marquetry (woodwork) shops. The Sorrentine Peninsula has views of Naples, Vesuvius and the Isle of Capri. The Amalfi Drive, connecting Sorrento and Amalfi, is a narrow road along the high cliffs above the Tyrrhenian Sea. Ferries and hydrofoils connect the town to Naples, Amalfi, Positano, Capri and Ischia. Limoncello, a digestif made from lemon rinds, alcohol, water and sugar, is produced in Sorrento along with citrus fruit, wine, nuts and olives. History Origins The Roman name for Sorrento was . From the 8th century BC the area had the presence of a community of indigenous villages, which was a crossing point for Etr ...

Taormina
Taormina ( , , also , ; scn, Taurmina) is a ''comune'' (municipality) in the Metropolitan City of Messina, on the east coast of the island of Sicily, Italy. Taormina has been a tourist destination since the 19th century. Its beaches on the Ionian sea, including that of Isola Bella, are accessible via an aerial tramway built in 1992, and via highways from Messina in the north and Catania in the south. On 26–27 May 2017 Taormina hosted the 43rd G7 summit. History The history of Taormina dates back to before Ancient Greece established its first colony on Sicily in 734 BCE. After the fall of the Western Roman Empire, Taormina continued to rank as one of the more important towns of the island. Taormina followed the history of Sicily in being ruled by successive foreign monarchs. After the Italian unification, Taormina began to attract well-off tourists from northern Europe, and it became known as a welcoming haven for gay men and artists. Main sights The present ...

Spiracle (arthropods)
A spiracle or stigma is the opening in the exoskeletons of insects and some spiders to allow air to enter the trachea. In the respiratory system of insects, the tracheal tubes primarily deliver oxygen directly into the animals' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles surrounding the spiracle. In order to open, the muscle relaxes. The closer muscle is controlled by the central nervous system, but can also react to localized chemical stimuli. Several aquatic insects have similar or alternative closing methods to prevent water from entering the trachea. The timing and duration of spiracle closures can affect the respiratory rates of the organism. Spiracles may also be surrounded by hairs to minimize bulk air movement around the opening, and thus minimize water loss. Although all insects have spiracles, only some spiders have them, such as orb weavers and wolf spiders. Ancestrally, spide ...
