Lioré et Olivier LeO H-15. The Lioré et Olivier Leo H-15 was a French twelve-seat civil flying boat, flown in a national contest in 1926. It did not win but set two load carrying records, one a world record.

Design and development

In 1926 the French government offered large prizes in a contest to produce new, multi-engined commercial seaplanes.  Compared with similar landplane competitions, few manufacturers offered a candidate; at the trials, held in July and August only the Lioré et Olivier LeO H-15 and the SPCA Météore 63 took part.

The LeO H-15 was a three-engined biplane with high aspect ratio, thin section wings of unequal span. The shorter span lower wing, with slight dihedral, was built into the hull and the upper wing was mounted on it without stagger or dihedral. The interplane struts were in parallel pairs, two outward leaning and two vertical outboard, and an interconnected central complex which both braced the wings and mounted two of its three  Gnome & Rhône 9Ab nine cylinder radial engines close inboard between the wings. The other was mounted on the upper wing over the hull.

Its hull had two steps, one under the wing trailing edge and the second further aft. The underside had a rounded, rather than V, section and was wider than its upper part. The pilot was positioned in an open cockpit just ahead of the leading edge of the wing and a "luxurious" passenger cabin, accommodating twelve, was accessed via a hatch in the nose. On each side a stabilizing float was mounted below the lower wing on extensions of the outer interplane struts, strengthened with another, inward pair.

The LeO H-15's fin was part of the hull and was roughly triangular in profile. It carried a vertical-edged, balanced rudder which extended to the lower fuselage.  A rectangular plan tailplane was mounted on the fin a little way above the fuselage, braced on each side with a parallel pair of struts to the lower fuselage and wires from the upper fin; like the rudder, the elevators were balanced.

Operational history

The LeO H-15 first flew on 10 June 1926, less than six weeks before the start of the trials on July 19 at Saint-Raphaël. It was required to achieve its Certificate of Airworthiness two days before the trials to take part. Its trials pilot was Lt. de Vaisseau Benoit. The Météore out-performed the LeO in the commercial flight tests and was judged safer and more comfortable for the passengers, though its take-offs took longer, it climbed more slowly and was less seaworthy. As a result, the Météore received the first prize of 100,000 francs and the LeO the 20,000 francs second prize.

During the trials the LeO H-15 set two records, both for aircraft carrying a load of . The first was a world duration record of 4 h 32 min 11 s and the second a French speed record over  at .

Project Unreality. Project Unreality was a video game console emulator for the Nintendo 64. It was notable for being one of the earliest attempts at Nintendo 64 emulation (predating UltraHLE by nearly a year), and the first Nintendo 64 emulator to successfully boot a commercial game.

History
Development on Project Unreality started in late 1997, just over a year after the launch of the Nintendo 64. In its earliest days, Project Unreality had few contemporaries; at the time, emulators for current-generation consoles were often hoaxes or "shells" with extremely limited emulation capabilities.

By early 1998, Project Unreality could emulate homebrew games to some extent. The emulator's initial release saw its ability to boot commercial games, a first for any Nintendo 64 emulator.

Discontinuation
In May 1998, lead programmer Michael Tedder announced that Project Unreality would be "put on the back burner for now", though no future updates were ever released. Slashdot later reported that one of Project Unreality's developers was hired to a game studio, leaving the emulator's development in limbo. This news coincided with Tedder's hiring to Z-Axis, where he continued to work until early 2000.

Though Tedder repeatedly claimed that Nintendo hadn't contacted him regarding Project Unreality, the rumor that Nintendo halted the emulator's development spread throughout the emulation scene; it has been suggested that UltraHLE's development was carried out in secret directly as a result of this rumor.

John Murphy (engineer). John A. Murphy is an American inventor and computer engineer credited with inventing ARCNET, the first commercial networking system, in 1976. He was working for Datapoint Corporation at the time. His biography appeared in the IT History Society website.

Background and career
Originally from Tulsa, Oklahoma, Murphy graduated from the University of Notre Dame in 1965 with a B.S. degree in electrical engineering. He first worked at IBM, then Motorola, Telex, and Singer Business Machines before joining Datapoint, where he led design of the computer networking system ARCNET. Victor Poor had established the R&D function at Datapoint as industry leading: with Harry Pyle, Poor co-created the architecture that was ultimately implemented in the first successful computer microprocessor, the Intel 8008.

ARCNET
Developed in 1976, ARCNET (Attached Resource Computer NETwork) was the first widely available networking system for microcomputers.

Datapoint had pioneered microprocessors; the challenge ARCNET addressed was how to facilitate the efficient transmission of information between different machines. In an interview with Len Shustek for the Computer History Museum, Murphy notes that Datapoint took ARCNET from concept to reality in "under a year and probably very much under a year." As the first commercial local area network, ARCNET found early success, but corporate struggles at Datapoint led to slower adoption in the 1980s, relative to other commercial alternatives like Ethernet. According to Techopedia, "ARCnet was the first simple networking based solution that provided for all kinds of transmission regardless of the transmission medium or the type of computer."

Cyclopropylacetylene. Cyclopropylacetylene is an hydrocarbon with the chemical formula . Under normal conditions, the substance is a colorless liquid. Cyclopropylacetylene is a precursor pharmaceuticals and other organic compounds.

Synthesis
Several methods have been published on the synthesis of cyclopropylacetylene. The earliest preparation starts with the chlorination of cyclopropylmethylketone with phosphorus pentachloride. Thereafter, the reaction product, 1-cyclopropyl-1,1-dichloroethane, is converted into cyclopropylacetylene via double dehydrochlorination. This occurs in presence of a strongly basic solution, such as potassium tert-butoxide in dimethyl sulfoxide:

However, the yield of this method is not substantial (20-25%). A one-pot synthesis of cyclopropylacetylene has been reported in which 5-chloro-1-pentyne reacts with n-butyl lithium or n-hexyl lithium. Cyclohexane is used as a solvent. The reaction is a metalation followed by a cyclization. The reaction product is then cooled, and an aqueous solution of ammonium chloride is added slowly. There is a two-phase mixture: a heavy water phase and a lighter organic phase containing cyclopropylacetylene.

Applications
Cyclopropylacetylene is used as reagent in organic reactions. It is, for example, a building block of the antiretroviral and psychotropic drug efavirenz. It can also be used in the azide-alkyne Huisgen cycloaddition.

Static fatigue. Static fatigue, sometimes referred to as delayed fracture, describes the progressive cracking and eventual failure of materials under a constant, sustained stress. (It is different from fatigue, which refers to the deformation and eventual failure of materials subjected to cyclical stresses.) With static fatigue materials experience damage or failure under stress levels that are lower than their normal ultimate tensile strengths. The exact details vary with the material type and environmental factors, such as moisture presence and temperature. This phenomenon is closely related to stress corrosion cracking.

Typical occurrence

Stress corrosion cracking 
Stress corrosion cracking (SCC) happens when a stressed material is in a corrosive (chemically destructive) environment.  One example of SSC embrittlement is when moisture increases static fatigue degradation of glass. SCC is also seen in hydrogen embrittlement and embrittlement of some polymers.

Plastic Deformation (Plastic Flow) 
Plastic deformation happens when stresses flatten, bend, or twist a material until it cannot return to its original shape. This can create cracks in the material and decrease its lifetime.

Testing 
Static fatigue tests can be used to determine the lifespan of a material with different loads and environmental conditions. However, accurately assessing a material's true static fatigue life presents challenges, as these tests often require an extended duration and there is significant variability in the results.

Examples of Static Fatigue and Stresses on Materials 
Plastic pipes under water or other fluids experience hydrodynamic forces that can result in fatigue. The pipes reach failure sooner as temperatures and exposure to aggressive substances increase.
