Year 230 (CCXXX) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Agricola and Clementinus (or, less frequently, year 983 Ab urbe condita). The denomination 230 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Antares (rocket)

Antares (), known during early development as Taurus II, is an expendable launch system developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems after Northrop Grumman acquired Orbital ATK) and the Yuzhnoye Design Bureau to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads heavier than 5,000 kg (11,000 lb) into low-Earth orbit, Antares is the largest rocket operated by Orbital ATK. Antares launches from the Mid-Atlantic Regional Spaceport and made its inaugural flight on April 21, 2013.NASA awarded Orbital a Commercial Orbital Transportation Services (COTS) Space Act Agreement (SAA) in 2008 to demonstrate delivery of cargo to the International Space Station. For these COTS missions Orbital intends to use Antares to launch its Cygnus spacecraft. In addition, Antares will compete for small-to-medium missions. Originally designated the Taurus II, Orbital Sciences renamed the vehicle Antares, after the star of the same name, on December 12, 2011.

The first four Antares launch attempts were successful. During the fifth launch on October 28, 2014, the rocket failed catastrophically, and the vehicle and payload were destroyed. The failure was traced to a fault in the first stage engines. After completion of a redesign program, the rocket had a successful return to flight on October 17, 2016, delivering cargo to the ISS.

BRP Laguna (LS-501)

BRP Laguna (LS-501) was an LST-1-class tank landing ship currently under the Philippine Navy. She was transferred to the Philippine Navy on 13 September 1976, operating as BRP Laguna (LT-501).Formerly known as the USS LST-230 , She was built for the United States Navy during World War II

LST-230 was laid down on 10 June 1943 at Seneca, III., by the Chicago Bridge & Iron Co.; launched on 12 October 1943; sponsored by Mrs. Lottie Reeks; and commissioned on 3 November 1943. She was previously known as BRP Laguna (LT-501) prior to a classification change implemented by the Philippine Navy starting April 2016

Boeing 727

The Boeing 727 is an American midsized, narrow-body three-engined jet aircraft built by Boeing Commercial Airplanes from the early 1960s to 1984. It can carry 149 to 189 passengers and later models can fly up to 2,700 nautical miles (5,000 km) nonstop. Intended for short and medium-length flights, the 727 can use relatively short runways at smaller airports. It has three Pratt & Whitney JT8D engines below the T-tail, one on each side of the rear fuselage with a center engine that connects through an S-duct to an inlet at the base of the fin. The 727 is the only Boeing trijet, as a commercial design entering production.

The 727 followed the 707, a quad-jet airliner, with which it shares its upper fuselage cross-section and cockpit design. The 727-100 first flew in February 1963 and entered service with Eastern Air Lines in February 1964; the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that December. The 727 became a mainstay of airlines' domestic route networks and was also used on short- and medium-range international routes. Passenger, freighter, and convertible versions of the 727 were built.

The highest production rate of the 727 was in the 1970s; the last 727 was completed in 1984. As of July 2018, a total of 44 Boeing 727s (2× 727-100s and 42× -200s) were in commercial service with 23 airlines, plus a few more in government and private use. Airport noise regulations have led to 727s being equipped with hush kits. Since 1964, there have been 118 fatal incidents involving the Boeing 727. Successor models include variants of the 737 and the 757-200. The last commercial passenger flight of the type was in January 2019.

Boeing 737

The Boeing 737 is a short- to medium-range twinjet narrow-body airliner developed and manufactured by Boeing Commercial Airplanes in the United States. Originally developed as a shorter, lower-cost twin-engine airliner derived from the 707 and 727, the 737 has developed into a family of thirteen passenger models with capacities from 85 to 215 passengers. The 737 is Boeing's only narrow-body airliner in production, with the 737 Next Generation (-700, -800, and -900ER) and the re-engined and updated 737 MAX variants also in use.

The 737 was originally envisioned in 1964. The initial 737-100 made its first flight in April 1967, and entered airline service in February 1968 with Lufthansa. Next, the lengthened 737-200 entered service in April 1968. In the 1980s Boeing launched the longer 737-300, -400, and -500 variants (referred to as the Boeing 737 Classic series) featuring CFM56 turbofan engines and wing improvements.

The Boeing 737 Next Generation (NG) was introduced in the 1990s, with a redesigned, increased span wing, upgraded "glass" cockpit, and new interior. The 737 NG comprises the 737-600, -700, -800, and -900 variants, with lengths ranging from 31.09 to 42.06 m (102 to 138 ft). Boeing Business Jet versions of the 737 NG are also produced. The 737 was revised again in the 2010s for greater efficiency, with the 737 MAX series featuring CFM LEAP-1B engines and improved winglets. The 737 MAX entered service in 2017 but, after a successful start, was grounded worldwide in March 2019 following two fatal crashes.

The 737 series is the highest-selling commercial jetliner in history. The 737 has been continuously manufactured since 1967; the 10,000th was rolled out on March 13, 2018, a MAX 8 destined for Southwest Airlines, and over 4,600 orders are pending. Assembly of the 737 is performed at the Boeing Renton Factory in Renton, Washington. Many 737s serve markets previously filled by 707, 727, 757, DC-9, and MD-80/MD-90 airliners, and the aircraft currently competes primarily with the Airbus A320 family. As of 2006, there were an average of 1,250 Boeing 737s airborne at any given time, with two either departing or landing somewhere every five seconds.

Cessna 182 Skylane

The Cessna 182 Skylane is an American four-seat, single-engined light airplane, built by Cessna of Wichita, Kansas. It has the option of adding two child seats, installed in the baggage area.

Introduced in 1956, the 182 has been produced in a number of variants, including a version with retractable landing gear, and is the second most popular Cessna model, after the 172.

DFS 230

The DFS 230 was a German transport glider operated by the Luftwaffe in World War II. It was developed in 1933 by the Deutsche Forschungsanstalt für Segelflug (DFS - "German Research Institute for Sailplane Flight") with Hans Jacobs as the head designer. The glider was the German inspiration for the British Hotspur glider and was intended for airborne assault operations.

In addition to the pilot, the DFS-230 glider had room for nine men who sat close together on a narrow bench located in the middle of the fuselage (half facing port, half facing starboard). Entry and exit to the cramped interior was by a single side door. The front passenger could operate its only armament, a machine gun. It was an assault glider, designed to land directly on top of its target, so it was equipped with a parachute brake. This allowed the glider to approach its target in a dive at an angle of eighty degrees and land within 20 metres (60 ft) of its target. It could carry up to 1,200 kg (2,600 lb) of cargo.

It played significant roles in the operations at Fort Eben-Emael, the Battle of Crete, and in the rescue of Benito Mussolini. It was also used in North Africa. However, it was used chiefly in supplying encircled forces on the Eastern Front such as supplying the Demyansk Pocket, the Kholm Pocket, Stalingrad, and the defenders of Festung Budapest (until February 12, 1945). Although production ceased in 1943, it was used right up to the end of the war, for instance, supplying Berlin and Breslau until May 1945.

By means of a cable running along the tow rope the pilots of the tow-plane and of the freight glider were able to communicate with each other which made blind flying possible, when necessary. The towing speed of the DFS-230 was approximately 190 km/h (116 mph). It dropped its landing gear as soon as it was safely in the air, and landed by means of a landing skid. The DFS-230 could be towed by a Ju 52 (which could tow two with difficulty), a He 111, a Ju 87, Hs 126, a Bf 110, or a Bf 109. The Ju 52 towed the glider using a 40 metres (131 ft) cable or, in bad weather, a much shorter rigid bar connected by an articulated joint to the tow aircraft. The DFS-230 had the highest glide ratio (18) of any World War 2 military glider other than the Antonov A-7. This was because it was thought that the glider had to be capable of a long approach during landing, so that it could be released a considerable distance from the target so the sound of the towing aircraft did not alert the enemy.

German submarine U-230

U-230 was a Type VIIC U-boat built for Nazi Germany's navy (Kriegsmarine) for service during World War II.

She was laid down on 25 November 1941, at the Krupp yard in Kiel as yard number 600, launched on 10 September, and commissioned on 24 October 1942, with Kapitänleutnant Paul Siegmann in command. Her First Officer, during her first three war patrols, was Herbert Werner, author of the best-selling postwar memoir Iron Coffins. She carried out three patrols and was a member of three wolfpacks before moving to the Mediterranean. She was scuttled there by her crew when the Allies landed near Toulon, France in August 1944.

List of unconstructed state highways in California

The following state highways in the U.S. state of California are entirely or partially unconstructed; in other words, their routings have been defined by state law, but no route has been adopted by the California Department of Transportation (Caltrans).

Mains electricity

Mains electricity (as it is known in the UK and Canada; US terms include grid power, wall power, and domestic power) is the general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses, and it is the form of electrical power that consumers use when they plug domestic appliances, televisions and electric lamps into wall outlets.

The two principal properties of the electric power supply, voltage and frequency, differ between regions. A voltage of (nominally) 230 V and a frequency of 50 Hz is used in Europe, most of Africa, most of Asia, much of South America and Australia. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other voltages exist, and some countries may have, for example, 230 V but 60 Hz. This is a concern to travellers, since portable appliances designed for one voltage and frequency combination may not operate with, or may even be destroyed by another. The use of different and incompatible plugs and sockets in different regions and countries provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.

Mains electricity by country

Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see Industrial and multiphase power plugs and sockets.) Some countries have more than one voltage available. For example, in North America most sockets are attached to a 120 V supply, but there is a 240 V supply available for large appliances. Often different sockets are mandated for different voltage or current levels.

Voltage, frequency, and plug type vary, but large regions may use common standards. Physical compatibility of receptacles may not ensure compatibility of voltage, frequency, or connection to earth (ground), including plugs and cords. In some areas, older standards may still exist. Foreign enclaves, extraterritorial government installations, or buildings frequented by tourists may support plugs not otherwise used in a country, for the convenience of travellers.

National Highway 230 (India)

For old National Highway 230,refer to National Highway 85 (India).

National Highway 230 (NH 230) is a National Highway in India.

No. 230 Squadron RAF

No. 230 Squadron is an RAF squadron, currently based at RAF Benson.

The squadron was part of Royal Air Force Germany, operating the Puma HC.1 there from 1980. Following the drawdown at the end of the Cold War, the squadron disbanded on 30 April 1992. This was short-lived however and the squadron reformed at RAF Aldergrove on 4 May 1992, again with the Puma HC.1.

The squadron is well experienced in night flying; almost a third of flights are undertaken after dark.

The 2004 Future Capabilities chapter of the UK Defence White Paper, Delivering Security in a Changing World announced a plan to reduce the squadrons Puma force by 6 helicopters. It was announced in late 2008 that the squadron was to move to RAF Benson by 2010. The Squadron re-equipped with Puma HC Mk2 in 2014 following removal from service of the Puma HC Mk1.

Section 230 of the Communications Decency Act

Section 230 of the Communications Decency Act of 1996 (a common name for Title V of the Telecommunications Act of 1996) is a landmark piece of Internet legislation in the United States, codified at 47 U.S.C. § 230. Section 230(c)(1) provides immunity from liability for providers and users of an "interactive computer service" who publish information provided by third-party users:

No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.

In analyzing the availability of the immunity offered by this provision, courts generally apply a three-prong test. A defendant must satisfy each of the three prongs to gain the benefit of the immunity:

The defendant must be a "provider or user" of an "interactive computer service."

The cause of action asserted by the plaintiff must treat the defendant as the "publisher or speaker" of the harmful information at issue.

The information must be "provided by another information content provider," i.e., the defendant must not be the "information content provider" of the harmful information at issue.

Series 30

The Series 30, often shortened as S30, is a software platform and application user interface created by Nokia for its entry level mobile phones, lower than Series 40. Some S30 phones are capable of running Java apps. In 2014, Microsoft acquired Nokia's mobile phones business and later discontinued S30 in favor of Series 30+.

The first Series 30 device was the Nokia 1100 from 2003. Originally, S30 was supposed to have just one menu key, but a second one was added with the release of the Nokia 1110. All S30 devices also don't have a 5-way d-pad, only a 4-way d-pad (except the Nokia 1100 which just has a 2-way d-pad).

Space group

In mathematics, physics and chemistry, a space group is the symmetry group of a configuration in space, usually in three dimensions. In three dimensions, there are 219 distinct types, or 230 if chiral copies are considered distinct. Space groups are also studied in dimensions other than 3 where they are sometimes called Bieberbach groups, and are discrete cocompact groups of isometries of an oriented Euclidean space.

In crystallography, space groups are also called the crystallographic or Fedorov groups, and represent a description of the symmetry of the crystal. A definitive source regarding 3-dimensional space groups is the International Tables for Crystallography (Hahn (2002)).
