Moth

Moths comprise a group of insects related to butterflies, belonging to the order Lepidoptera. Most lepidopterans are moths and there are thought to be approximately 160,000 species of moth, many of which are yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species.

Differences between butterflies and moths

While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.

Although the rules for distinguishing moths from butterflies are not hard and fast, one very good guiding principle is that butterflies have thin antennae and (with one exception) have small balls or clubs at the end of their antennae. Moth antennae can be quite varied in appearance, but in particular lack the club end. The divisions are named by this principle: "club-antennae" (Rhopalocera) or "varied-antennae" (Heterocera).

Moth (dinghy)

The Moth Class is the name for a small development class of sailing dinghy. Originally a cheap home built sailing boat designed to plane, now it is an expensive largely commercially produced boat designed to hydroplane on foils. Many of the older design Moths still exist and are fun recreational boats but far slower.

History

Beginnings

The current International Moth is a result of merging two separate but similar historical developments. The first occurred in Australia in 1928 when Len Morris built a cat rigged (single sail) flat bottomed scow(horizontal bow rather than the "normal" vertical) to sail on Andersons' Inlet at Inverloch, a seaside resort, 130 km from Melbourne. The scow was hard chined, was 11 feet (3.4 m) long, and carried 80 square feet (7.4 m²) in single mainsail. The craft was named "Olive" after his wife. The construction was timber with an internal construction somewhat like Hargreave's box kite. "Olive's" performance was so outstanding, that a similar boat "Whoopee" was built. Len Morris then sold "Olive", and built another boat called "Flutterby", and with those three boats, the Inverloch Yacht Club was formed. Restrictions for the class known as the Inverloch Eleven Footer class were then drawn up, with the distinguishing characteristic that of being not a one-design boat but rather that of a boat permitting development within the set of design parameters.

Moth (album)

Moth is the third full-length album by American indie band Chairlift, released in the United States via Columbia Records on January 22, 2016.

Critical reception

Before being released, Consequence of Sound, Pitchfork, Stereogum, and Billboard included Moth in their lists of most anticipated albums of 2016, and it has received generally favorable reviews.Brooklyn Magazine named the album its "Album of the Month" for January 2016.

In a positive review for Exclaim!, Stephen Carlick wrote that "with Moth, Chairlift make a strong claim to being one of pop music's best songwriting teams, with the production and vocal chops to bring their compositions fully and vibrantly to life."Rolling Stone praised the album as "a record where love, music and love for music come together beautifully."

Borax

Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. Powdered borax is white, consisting of soft colorless crystals that dissolve easily in water.

Borax has a wide variety of uses. It is a component of many detergents, cosmetics, and enamel glazes. It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound, in the manufacture of fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, and as a precursor for other boron compounds.

In artisanal gold mining, the borax method is sometimes used as a substitute for toxic mercury in the gold extraction process. Borax was reportedly used by gold miners in parts of the Philippines in the 1900s.

The term borax is used for a number of closely related minerals or chemical compounds that differ in their crystal water content, but usually refers to the decahydrate. Commercially sold borax is partially dehydrated.

Borax (disambiguation)

Borax is Sodium borate, a boron-containing mineral.

BORAX experiments

The BORAX Experiments were a series of safety experiments on boiling water nuclear reactors conducted by Argonne National Laboratory in the 1950s and 1960s at the National Reactor Testing Station in eastern Idaho. They were performed using the five BORAX reactors that were designed and built by Argonne. BORAX-III was the first nuclear reactor to supply electrical power to the grid in the United States in 1955.

Evolution of BORAX

This series of tests began in 1952 with the construction of the BORAX-I nuclear reactor. BORAX-I experiment proved that a reactor using direct boiling of water would be practical, rather than unstable, because of the bubble formation in the core. Subsequently the reactor was used for power excursion tests which showed that rapid conversion of water to steam would safely control the reaction. The final, deliberately destructive test in 1954 produced an unexpectedly large power excursion that "instead of the melting of a few fuel plates, the test melted a major fraction of the entire core." However, this core meltdown and release of nuclear fuel and fission products provided additional useful data to improve mathematical models. The tests proved key safety principles of the design of modern nuclear power reactors. Design power of BORAX-I was 1.4 megawatts thermal. The BORAX-I design was a precursor to the SL-1 plant, which was sited nearby and began operations in 1958. The principles discovered in the BORAX-I experiments helped scientists understand the issues which contributed to the fatal incident at SL-1 in 1961.
