Serpent (software). Serpent is a continuous-energy multi-purpose three-dimensional Monte Carlo particle transport code. It is under development at VTT Technical Research Centre of Finland since 2004.  Serpent was originally known as Probabilistic Scattering Game (PSG) from 2004 to the first pre-release of Serpent 1 in October 2008. The development of Serpent 2 was started in 2010. The current stable version Serpent 2.2.0 was released in May 2022.

Serpent was originally developed to be a simplified neutron transport code for reactor physics applications. Its main focus was on group constant generation with two-dimensional lattice calculations. Burnup calculation capability was included early on. Nowadays Serpent is used in a wide range of applications from the group constant generation to coupled multi-physics applications, fusion neutronics and radiation shielding. In addition to the original neutron transport capabilities, Serpent is able to perform photon transport.

Sodium metatungstate. Sodium metatungstate is the inorganic compound with the formula Na6[H2W12O40], sometimes written 3Na2WO4·9WO3·H2O.  It is also referred to as sodium polytungstate (SPT).  This salt has been used in the manufacture of dense aqueous solutions. Sodium metatungstate exists as white solid. The anion is the polyoxotungstate [H2W12O40]6-, which features six-coordinated tungsten(VI) centers interconnected with doubly- and triply bridging oxo ligands.

Due to its very high solubility in water (max. density 3.1 g/cm3), SPT is widely used as to produce "heavy liquid" for gravity separation (sink /float analysis) and density gradient centrifugation. It has significant advantages when compared to zinc chloride solution or the toxic halogenated carbons for sink-swim analysis. Aqueous SPT is non-toxic (unlike the denser Clerici solution), non-flammable, odorless, reusable and additionally it has a low viscosity.

Luna Ring. Luna Ring is a speculative engineering project which consists of a series of solar generators, disposed around the equator of the Moon, that could send the generated electric energy back to the Earth via microwaves from the near side of the Moon. The project was proposed by Japanese construction firm Shimizu Corporation, after the 2011 Tōhoku earthquake and tsunami destroyed the Fukushima Daiichi Nuclear Power Plant, creating public opposition against nuclear electric energy. Until then, Japan had relied heavily on nuclear power.

Construction 

The construction of a concrete ring on the Moon's equator to support the solar panels would be performed by robots that would be teleguided from Earth. Then, the solar panels would be placed on the concrete layer, and connected to microwave and laser transmitting stations. The energy sent to Earth that way could be captured by receiving stations all through the day. The fact that the ring would surround the entire moon would mean that at least half of it would always be lit by the sun, resulting in constant electric production.

In 2013, Shimizu Corporation stated that the construction of the Luna Ring could start as early as 2035. However, the practical drawbacks of putting such a technically vast and complex project into place could hamper its construction, even if it could pave the way for simpler projects in clean energy production.

Zmaj Aircraft. Zmaj (), officially named Fabrika aeroplana i hidroaviona Zmaj (English: Airplane and Hydroplane Factory Zmaj), was a Yugoslav aircraft manufacturer.

History

The company was founded in 1927 and it was the third aeronautical factory in Serbia. At the beginning it manufactured aircraft under French license, and in 1932 it started with local planes designed by Jovan Petrović and Dragoljub Šterić. Several types of aircraft were manufactured by Zmaj, among them passenger Spartans for the domestic airliner Aeroput. Zmaj workshops manufactured 359 aircraft up until 1946, when the factory stopped manufacturing for aviation industry purposes and the company was nationalised and merged with Rogožarski into Ikarus.

Hydrodynamica. Hydrodynamica (Latin for Hydrodynamics) is a book published by Daniel Bernoulli in 1738. The title of this book eventually christened the field of fluid mechanics as hydrodynamics.

Contents 
The book deals with fluid mechanics and is organized around the idea of conservation of energy, as received from Christiaan Huygens's formulation of this principle. The book describes the theory of water flowing through a tube and of water flowing from a hole in a container. In doing so, Bernoulli explained the nature of hydrodynamic pressure and discovered the role of loss of vis viva in fluid flow, which would later be known as the Bernoulli principle. The book also discusses hydraulic machines and introduces the notion of work and efficiency of a machine. In the tenth chapter, Bernoulli discussed the first model of the kinetic theory of gases. Assuming that heat increases the velocity of the gas particles, he demonstrated that the pressure of air is proportional to kinetic energy of gas particles, thus making the temperature of gas proportional to this kinetic energy as well.

E. C. Cracknell. Edward Charles Cracknell (1831 – 14 January 1893) was an electrical engineer, Superintendent of Electric Telegraphs, New South Wales, and Lieutenant-Colonel commanding the Submarine Miners of the New South Wales Militia. He is considered Australia's third telegraph pioneer, after S. W. McGowan of Victoria and Charles Todd in South Australia.

History
Cracknell was born in Rochester, Kent, England, and educated at Oxford. In November 1855 he left for Adelaide in company with (later Sir) Charles Todd, head of the South Australian Post and Telegraph Department, having been selected by Todd as his assistant and future successor. They both came out to South Australia aboard the Irene, and promptly set about installing the line from Adelaide to Port Adelaide and The Semaphore, replacing a less permanent privately operated line financed and constructed by James MacGeorge. Around the end of 1857, he was appointed assistant to Ben Hay Martindale ("Captain Martindale"), Superintendent of Telegraphs in New South Wales, and on 26 January 1858 opened the telegraph line from Sydney to Liverpool, a distance of . This was the third line opened by the Telegraphic Department, the first being between Sydney and Parramatta, and the second Sydney with South Head.
Cracknell succeeded Captain Martindale as Superintendent in 1861, with P. B. Walker as assistant. In 1880 he represented New South Wales at the Berlin Postal Conference. He was a strong advocate for the illumination of Sydney by electric light.

Military
Cracknell was interested in military science, and prominent in promoting the shore defence of Sydney Harbour by means of torpedoes. In April 1874 he was commissioned lieutenant in the Torpedo Corps of the Naval Brigade, which in 1877 became the Submarine Miners Corps of the NSW Military Forces, and was promoted to the rank of major. On 6 April 1886 he was gazetted lieutenant colonel commanding.

He prepared "torpedo" defences at Port Jackson, Newcastle and Botany Bay.

Death
Cracknell died after a heart attack, and was accorded a full military funeral before burial at Waverley Cemetery.

P. B. Walker succeeded him, as Engineer-in-Chief of Telegraphs.

Family
Cracknell married Margaret Cunningham in Rochester c. 1853; they had three surviving daughters and one son:
Ada Sophia Cracknell (27 September 1856 in North Adelaide – ) married Ernest Collingwood Colquhoun on 28 August 1885
Edward William Cracknell (born 26 November 1858 – 15 December 1931) was architect and engineer remembered for advocating alternative route for South Gippsland railway line.
Eva Florence Cracknell (29 April 1861 – ) married A. C. F. Webb on 23 November 1892
Alice Ellen Cracknell (c. 1872 – 13 April 1891)
They had a home "Richmond" on Edgecliffe Road, Sydney

His brother William John Cracknell (died 1 December 1898) was for many years Superintendent of Telegraphs in Queensland.

Windstar YF-80. The Windstar YF-80 is an American single seat homebuilt replica of the Lockheed F-80.

Design and development

The YF-80 is a two-thirds scale replica of a Lockheed F-80 or T-33. The aircraft is a composite construction, single engine, low wing design with retractable tricycle landing gear. The tip tanks are removable for aerobatic flight. The aircraft is powered by a Chevy 350 V-8 turbocharged engine driving a turbine thrust section. The thrust section is driven by belts with high gear ratios to drive the turbine closer to the rotational speed it was originally designed for.

The aircraft project was intended to showcase the Davis engine technology with a static prototype displayed in 1977. Burt Rutan was approached to build the composite fuselage, but the US$240,000 cost estimate was declined. Davis attempted to produce a production prototype fuselage for US$80,000. By 1987 the project was not complete, resulting in a court case between investors. The prototype was re-engined with a Turbomeca Marboré II turbine engine as the Stargate YT-33.

Thermal transpiration. Thermal transpiration (or thermal diffusion) refers to the thermal force on a gas due to a temperature difference. Thermal transpiration causes a flow of gas in the absence of any other pressure difference, and is able to maintain a certain pressure difference called thermomolecular pressure difference in a steady state. The effect is strongest when the mean free path of the gas molecules is comparable to the dimensions of the gas container.

Thermal transpiration appears as an important correction in the readings of vapor pressure thermometers, and the effect is historically famous as being an explanation for the rotation of the Crookes radiometer.
