Continental CD-230. The Continental CD-230 is a four-cylinder, horizontally opposed aircraft Diesel engine produced by Continental Motors, Inc.
The engine received its type certificate from the US Federal Aviation Administration on December 19, 2012, under the official TD-300-B designation.
A later revision adds the TD-300-C with a higher critical altitude.

Design and development
In 2008, Teledyne Continental's new president, Rhett Ross, announced that the company is very concerned about future availability of 100LL avgas, and as a result will develop a Diesel engine in the  range for certification in 2009 or 2010.

Rather than develop a new Diesel engine from scratch, Continental decided to license an existing design to develop. The company did not release details on which engine they licensed, but the aviation media have identified it as the French SMA SR305-230 engine.

Antimony(III) sulfate. Antimony sulfate, Sb2(SO4)3, is a hygroscopic salt formed by reacting antimony or its compounds with hot sulfuric acid.  It is used in doping of semiconductors and in the production of explosives and fireworks.

Structure
Antimony(III) sulfate consists of interconnected SbO6 octahedra, which the corners are bonded to the sulfate ion.

Production
Antimony(III) sulfate was first produced in 1827 by the reaction of antimony(III) oxide and 18 molar sulfuric acid at 200 °C:

The concentration of the sulfuric acid is important, as a lower concentration will produce basic antimony oxides, while a higher concentration will produce antimony(III) pyrosulfate. The reaction of elemental antimony and 18 M sulfuric acid will also produce antimony(III) sulfate:

Chemical properties
Antimony sulfate is deliquescent, hydrolyzing in moist air and water, producing various basic antimony oxides and antimony(III) oxide. It is soluble in acids.

Uses
Owing to its solubility, antimony sulfate has uses in the doping of semiconductors. It is also used for coating anodes in electrolysis and in the production of explosives and fireworks.

Safety
Antimony(III) sulfate causes irritation to the skin and mucous membranes.

Natural occurrence
Natural analogue of the exact compound is yet unknown. However, basic hydrated Sb sulfates are known as the minerals klebelsbergite and coquandite.

Siemens (unit). The siemens (symbol: S) is the unit of electric conductance, electric susceptance, and electric admittance in the International System of Units (SI). Conductance, susceptance, and admittance are the reciprocals of resistance, reactance, and impedance respectively; hence one siemens is equal to the reciprocal of one ohm () and is also referred to as the mho. The siemens was adopted by the IEC in 1935, and the 14th General Conference on Weights and Measures approved the addition of the siemens as a derived unit in 1971.

The unit is named after Ernst Werner von Siemens. In English, the same word siemens is used both for the singular and plural. Like other SI units named after people, the symbol (S) is capitalized but the name of the unit is not. For the siemens this distinguishes it from the second, symbol (lower case) s.

The related property, electrical conductivity, is measured in units of siemens per metre (S/m).

Definition 
For an element conducting direct current, electrical resistance  and electrical conductance  are defined as

where  is the electric current through the object and  is the voltage (electrical potential difference) across the object.

The unit siemens for the conductance G is defined by
 
where  is the ohm,  is the ampere, and  is the volt.

For a device with a conductance of one siemens, the electric current through the device will increase by one ampere for every increase of one volt of electric potential difference across the device.

The conductance of a resistor with a resistance of five ohms, for example, is (5 Ω)−1, which is equal to a conductance of 200 mS.

Mho 

A historical equivalent for the siemens is the mho (). The name is derived from the word ohm spelled backwards as the reciprocal of one ohm, at the suggestion of Sir William Thomson (Lord Kelvin) in 1883. Its symbol is an inverted capital Greek letter omega: .

NIST's Guide for the Use of the International System of Units (SI) refers to the mho as an "unaccepted special name for an SI unit", and indicates that it should be strictly avoided.

The SI term siemens is used universally in science and often in electrical applications, while mho is still used in some electronic contexts.

The inverted capital omega symbol (℧), while not an official SI abbreviation, is less likely to be confused with a variable than the letter "S" when writing the symbol by hand. The usual typographical distinctions (such as italic for variables and roman for units) are difficult to maintain. Likewise, it is difficult to distinguish the symbol "S" (siemens) from the lower-case "s" (seconds), potentially causing confusion. So, for example, a pentode’s transconductance of  might alternatively be written as  or  (most common in the 1930s) or .

The ohm had officially replaced the old "siemens unit", a unit of resistance, at an international conference in 1881.

Canadian Pacific Air Lines Flight 301. 

Canadian Pacific Air Lines Flight 301 was a scheduled passenger flight from Honolulu, Hawaii to Nadi, Fiji. On 22 July 1962, it was being operated by a Bristol Britannia 314 four-engine turboprop airliner of Canadian Pacific Air Lines, registered CF-CZB. On departure from Honolulu International Airport, the aircraft had engine problems; while attempting a subsequent return and landing on three engines, the crew initiated a go-around that resulted in the plane crashing on the airfield, killing 27 of the 40 on board. It was the worst civil air carrier accident in Hawaii's history.

Accident
Shortly after take-off from Honolulu, the crew received an engine fire warning for the number one engine, which they feathered. They then jettisoned fuel before returning to Honolulu 40 minutes later. Their three-engined approach appeared to be normal, but at the last minute the crew decided to go around and attempt another approach.

The aircraft then banked and veered to the left, and the left wing tip hit the ground about 550' from the center of the runway. The aircraft disintegrated as it moved across the airfield before hitting some heavy earth-moving equipment. Apart from the rear fuselage and tail, the aircraft was destroyed by fire. Thirteen on board escaped, but 7 crew and 20 passengers were killed.

Aircraft
The aircraft, a Bristol Britannia 314 four-engined turboprop, was built in the United Kingdom, and first flew on 14 April 1958. It was delivered new to Canadian Pacific Air Lines on 29 April 1958, and was originally named Empress of Vancouver (later renamed Empress of Lima).

Probable cause
The accident investigation board concluded the probable cause of the accident was "the attempted three-engine go-around, when the aircraft was in a full landing configuration, at insufficient airspeed and altitude to maintain control."

James W. Jones. James William Jones ISO (1843 – 26 April 1920) was a South Australian surveyor and senior public servant.

Career
Jones was born in Waymouth Street, Adelaide, the son of prominent civil engineer Thomas Jones.
Thomas Jones (5 December 1809 – c. 20 November 1892) was a civil engineer born in Cowbridge in Glamorganshire, Wales, who arrived in Adelaide on 7 July 1840. He supervised construction of the City Bridge (on what is now King William Road) in 1843, the Port Elliot breakwater, and the Port Elliot to Goolwa tramway from 1853 to 1856. He remained at Port Elliot as engineer and supervisor of the tramway until 1871. He was appointed Town Surveyor for Moonta in 1872 and works supervisor for the (Yorke) Peninsula Road Board in 1875. He designed the Anglican Church in Moonta, completed 1874. He was the founder of the Manchester Unity of Oddfellows in South Australia.

He was educated at J. L. Young's Adelaide Educational Institution, and was soon working for his father on the Port Elliot to Goolwa tramway, for which his father received official criticism. He joined the State public service as a draughtsman in 1865 and was appointed Chief Surveyor then Deputy Surveyor-General in the Department of Survey and Crown Lands. He explored the area north-east of Eucla in 1880, and discovered the Kudna rockhole and catacombs, an immense network of limestone caves, lakes and underground passages under the Nullarbor Plain. He was appointed Conservator of Water in 1887 and Secretary to the Commissioner of Works in 1902. He was secretary of the South Australia branch of the Royal Geographical Society of Australasia from its foundation in 1885 to 1894. He was elected president of the Institute of Surveyors in 1912. He was chairman and president of the Harbors and Marine Board in 1914. He was secretary of the Cheer-Up Society during the First World War.
He was appointed Companion of the Imperial Service Order in 1911.
His retirement in 1914 was marked by a farewell from a large congregation of fellow-officers.

Recognition
Jones Island (South Australia) was named for him.

Nowotny phase. In inorganic chemistry, a Nowotny chimney ladder phase (NCL phase) is a particular intermetallic crystal structure found with certain binary compounds. NLC phases are generally tetragonal and are composed of two separate sublattices. The first is a tetragonal array of transition metal atoms, generally from group 4 through group 9 of the periodic table. Contained within this array of transition metal atoms is a second network of main group atoms, typically from group 13 (boron group) or group 14 (carbon group). The transition metal atoms form a chimney with helical zigzag chain. The main-group elements form a ladder spiraling inside the transition metal helix.

The phase is named after one of the early investigators H. Nowotny. Examples are RuGa2, Mn4Si7, Ru2Ge3, Ir3Ga5, Ir4Ge5 V17Ge31, Cr11Ge19, Mn11Si19, Mn15Si26, Mo9Ge16, Mo13Ge23, Rh10Ga17, and Rh17Ge22.

In RuGa2 the ruthenium atoms in the chimney are separated by 329 pm. The gallium atoms spiral around the Ru chimney with a Ga–Ga intrahelix distance of 257 pm. The view perpendicular to the chimney axis is that of a hexagonal lattice with gallium atoms occupying the vertices and ruthenium atoms occupying the center. Each gallium atom bonds to 5 other gallium atoms forming a distorted trigonal bipyramid. The gallium atoms carry a positive charge and the ruthenium atoms have a formal charge of −2 (filled 4d shell).

In Ru2Sn3 the ruthenium atoms spiral around the tin inner helix. In two dimension the Ru atoms form a tetragonal lattice with the tin atoms appearing as triangular units in the Ru channels.

The occurrence of a LCP phase can be predicted by the so-called 14 electron rule. In it the total number of valence electrons per transition metal atom is 14.

Aggregate modulus. In relation to biomechanics, the aggregate modulus (Ha) is a measurement of the stiffness of a material at equilibrium when fluid has ceased flowing through it. The aggregate modulus can be calculated from Young's modulus (E) and the Poisson ratio (v).

The aggregate modulus of a similar specimen is determined from a unidirectional deformational testing configuration, i.e., the only non-zero strain component is E11. This configuration is opposed to the Young's modulus, which is determined from a unidirectional loading testing configuration, i.e., the only non-zero stress component is, say, in the e1 direction.  In this test, the only non-zero component of the stress tensor is T11.

EOn. eOn was a volunteer computing project running on the Berkeley Open Infrastructure for Network Computing (BOINC) platform, which uses theoretical chemistry techniques to solve problems in condensed matter physics and materials science.  It was a project of the Institute for Computational Engineering and Sciences at the University of Texas.

Traditional molecular dynamics can accurately model events that occur within a fraction of a millisecond.  In order to model events that take place on much longer timescales, Eon combines transition state theory with kinetic Monte Carlo.  The result is a combination of classical mechanics and quantum methods like density functional theory.

Since the generation of new work units depended on the results of previous units, the project could only give each host a few units at a time.

On May 26, 2014, it was announced that eOn would be retiring from BOINC.

Rex Smith Aeroplane Company. Rex Smith Aeroplane Company was an American aircraft manufacturer in College Park, Maryland.

The founder, Rex Smith, was an inventor and a patent attorney. He placed his offices in Washington D.C., and operations at College Park Airport. The company was capitalized with $500,000 in 1910 with Victor J Evans as president and Rex Smith as Vice president.

In 1911, Rex Smith moved his hangar to line up with the Army Aviation School, and hired Frank Kastory from Anzani, and Abraham Whalomie Raygorodsky from Russia. He test flew Smith aircraft alongside Fox engine powered Curtiss aircraft. Rex also hired Tony Jannus, and Paul Peck as test pilots. In a stroke of coincidence, flying at the same airport at the same time was another military aviator, Paul W. Beck.

The Rex Smith Biplane was used in the successful April 3, 1911 U.S. Army Signal Corps experiments in wireless communications. Potomac river pontoon experiments on April 5, were not as successful, with the aircraft plowing into the water headfirst nearly drowning the test pilot Jannus. Just two days later the machine was ready again. Janus took up actor Nat M. Wills, and later two female passengers at the same time. Marking the first time an aircraft flew with more than one passenger in the United States.

The Signal Corps did not buy any Smith Biplanes, they did however use them from time to time to train pilots to fly the Curtiss aircraft at the same field.
