Seah (unit)

The se'ah or seah (Hebrew: סאה‎) is a unit of dry measure of ancient origin used in Halakha (Jewish law), which equals one third of an ephah, or bath. Its size in modern units varies widely according to the criteria used for defining it.

According to Herbert G. May, chief editor of two classic Bible-related reference books, the bath may be archaeologically determined to have been about 5.75 gallons (22 liters) from a study of jar remains marked 'bath' and 'royal bath' from Tell Beit Mirsim. Since the bath unit has been established to be 22 litres, 1 se'ah would equal 7.33 litres or 7.33dm³.

In the context of a mikveh, a se'ah can be about twice as much in order to accommodate even the most stringent rabbinical ruling on immersion. A mikveh must, according to the classical regulations, contain enough water to cover the entire body of an average-sized person; based on a mikveh with the dimensions of 3 cubits deep, 1 cubit wide, and 1 cubit long, the necessary volume of water was estimated as being 40 se'ah of water. The exact volume referred to by a seah is debated, and classical rabbinical literature specifies only that it is enough to fit 144 eggs; most Orthodox Jews use the stringent ruling of the Avrohom Yeshaya Karelitz, according to which one seah is 14.3 litres, and therefore a mikveh must contain approximately 575 litres . This volume of water could be topped up with water from any source, but if there were less than 40 seahs of water in the mikveh, then the addition of 3 or more pints of water from an unnatural source would render the mikveh unfit for use, regardless of whether water from a natural source was then added to make up 40 seahs from a natural source; a mikveh rendered unfit for use in this way would need to be completely drained away and refilled from scratch.

Hobart-class destroyer

The Hobart class is a ship class of three air warfare destroyers (AWDs) being built for the Royal Australian Navy (RAN). Planning for ships to replace the Adelaide-class frigates and restore the capability last exhibited by the Perth-class destroyers began by 2000, initially under acquisition project SEA 1400, which was redesignated SEA 4000. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force (plus assets ashore) from aircraft and missile attack, the planned Australian destroyers are expected to also operate in anti-surface, anti-submarine, and naval gunfire support roles.

Planning for the Australian Air Warfare Destroyer (as the class was known until 2006) continued through the mid-2000s, with the selection of the Aegis combat system as the intended combat system and ASC as the primary shipbuilder in 2005. In late 2005, the AWD Alliance was formed as a consortium of the Defence Materiel Organisation (DMO), ASC, and Raytheon. Between 2005 and 2007, Gibbs & Cox's Evolved Arleigh Burke-class destroyer concept and Navantia's Álvaro de Bazán-class frigate competed for selection as the AWD design. Although the Arleigh Burke design was larger and more capable, the Álvaro de Bazán design was selected in June 2007 as it was an existing design, and would be cheaper, quicker, and less risky to build.

Securities Exchange Act of 1934

The Securities Exchange Act of 1934 (also called the Exchange Act, '34 Act, or 1934 Act) (Pub.L. 73–291, 48 Stat. 881, enacted June 6, 1934, codified at 15 U.S.C. § 78a et seq.) is a law governing the secondary trading of securities (stocks, bonds, and debentures) in the United States of America. A landmark of wide-ranging legislation, the Act of '34 and related statutes form the basis of regulation of the financial markets and their participants in the United States. The 1934 Act also established the Securities and Exchange Commission (SEC), the agency primarily responsible for enforcement of United States federal securities law.

Companies raise billions of dollars by issuing securities in what is known as the primary market. Contrasted with the Securities Act of 1933, which regulates these original issues, the Securities Exchange Act of 1934 regulates the secondary trading of those securities between persons often unrelated to the issuer, frequently through brokers or dealers. Trillions of dollars are made and lost each year through trading in the secondary market.

Dart (comics)

Dart (Jill August) is a fictional Image Comics superhero. Created by Erik Larsen, she first appeared in 1992, in Savage Dragon #2 (ongoing series).

Publication history

Dart has appeared in numerous issues of Savage Dragon as a supporting character, as well as being a major character in the Freak Force series and subsequent mini-series. In February 1996, she received her own eponymous three-issue limited series, written by Julie Ditrich and Bruce Love with artwork by Jozef Szekeres.

Fictional character biography

Jill August was born on August 12, 1969, in Detroit, Michigan. She grew up timid and demoralized, witnessing her mother's constant spousal abuse at the hands of her father, and her friends' abuse at the hands of a cruel coach at school. She witnessed her father beat her mother to death, a crime for which he was sentenced to life in prison, effectively leaving Jill an orphan.

As a teenager, Jill saw a female friend being assaulted by several men in a bar in Detroit. Attempting to intervene, she fell against a dartboard hung on the barroom wall, and the men began to attack her as well. Instinctively, she used the darts to defend herself, throwing them at her attackers with astonishing accuracy, seriously injuring all of them. She subsequently decided to use this newly discovered skill to both help others and manage her feelings of helplessness (and the rage that comes with those feelings).

Dart (missile)

Darts are missile weapons, designed to fly such that a sharp, often weighted point will strike first. They can be distinguished from javelins by fletching (i.e., feathers on the tail) and a shaft that is shorter and/or more flexible, and from arrows by the fact that they are not of the right length to use with a normal bow.

The term has been used to describe an extremely wide variety of projectiles, from heavy spear-like ammunition for siege engines or atlatls to tiny poisoned needles for use in blowguns.

Plumbatae or martiobarbuli

Plumbatae or martiobarbuli were lead-weighted darts carried by infantrymen in Antiquity and the Middle Ages. The first examples seem to have been carried by the Ancient Greeks from about 500 B.C. onwards, but the best-known users were the late Roman and Byzantine armies. The best written source for these tactical weapons is Vegetius's treatise known as De Re Militari (1.17):

Prehistory

Some of the earliest evidence of advanced tool use includes remnants of an early type of dart, which can be considered the ancestor of arrows as well as bows (see Operation). Reconstructions of this system have a range of over one hundred metres (yards) and can penetrate several centimetres of oak. This technology was used worldwide from the Upper Palaeolithic (late Solutrean, c. 18,000-16,000 BC) until the development of archery made it obsolete (see Replacement).
