Genera

Geminigeraceae is a family of cryptophytes containing the five genera Geminigera , Guillardia , Hanusia, Proteomonas and Teleaulax. [1] They are characterised by chloroplasts containing Cr-phycoerythrin 545, and an inner periplast component (IPC) comprising "a sheet or a sheet and multiple plates if diplomorphic". The nucleomorphs are never in the pyrenoid, and there is never a scalariform furrow. The cells do, however, have a long, keeled rhizostyle with lamellae (wings). [1]

<span class="mw-page-title-main">Iodine-131</span> Isotope of iodine

Iodine-131 is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production. It also plays a major role as a radioactive isotope present in nuclear fission products, and was a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Fukushima nuclear crisis. This is because 131I is a major fission product of uranium and plutonium, comprising nearly 3% of the total products of fission. See fission product yield for a comparison with other radioactive fission products. 131I is also a major fission product of uranium-233, produced from thorium.

A film poster is a poster used to promote and advertise a film primarily to persuade paying customers into a theater to see it. Studios often print several posters that vary in size and content for various domestic and international markets. They normally contain an image with text. Today's posters often feature printed likenesses of the main actors. Prior to the 1980s, illustrations instead of photos were far more common. The text on film posters usually contains the film title in large lettering and often the names of the main actors. It may also include a tagline, the name of the director, names of characters, the release date, and other pertinent details to inform prospective viewers about the film.

Iodine-123 (123I) is a radioactive isotope of iodine used in nuclear medicine imaging, including single-photon emission computed tomography (SPECT) or SPECT/CT exams. The isotope's half-life is 13.2230 hours; the decay by electron capture to tellurium-123 emits gamma radiation with a predominant energy of 159 keV. In medical applications, the radiation is detected by a gamma camera. The isotope is typically applied as iodide-123, the anionic form.

Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories:

An intentionally blank page is a page that has no content and may be unexpected. Such pages may serve purposes ranging from place-holding to space-filling and content separation. Sometimes, these pages carry a notice such as "This page was intentionally left blank." Such notices typically appear in printed works, such as legal documents, manuals, and exam papers, in which the reader might otherwise suspect that the blank pages are due to a printing error and where missing pages might have serious consequences.

<span class="mw-page-title-main">Bergère hat</span> Flat-brimmed straw hat with a shallow crown

A bergère hat is a flat-brimmed straw hat with a shallow crown, usually trimmed with ribbon and flowers. It could be worn in various ways with the brim folded back or turned up or down at whim. It is also sometimes called a milkmaid hat. It was widely worn in the mid-18th century, and versions may be seen in many British and French paintings of the period, such as The Swing by Fragonard, and in portraits by Thomas Gainsborough and Johann Zoffany, amongst others. It has been suggested that the hat was named after Madame Bergeret, who is holding a shepherdess-style hat in a Boucher portrait painted c.1766.

Acropora batunai is a species of acroporid coral that was described by Carden Wallace in 1997. Found in protected, shallow reefs, it occurs in a marine environment at depths of up to 44 m (144 ft). The species is rated as vulnerable on the IUCN Red List, with a decreasing population, and is extremely fragile. It can be found over a large area but, overall, is not common.

Mandaic lead rolls, sometimes also known as Mandaic amulets or sheets, which are related to Palestinian and Syrian metal amulets, are a specific term for a writing medium containing incantations in the Mandaic script incised onto lead sheets with a pin. Some Mandaic incantations are found on gold and silver sheets. They are rolled up and then inserted into a metal capsule with loops on it to be worn around the neck on a string or necklace.
