Breda Ba.79S. The Breda Ba.79S was a single-engine four-seat high-wing private aircraft built in Italy in the late 1930s.  Only a few were produced.

Design and development
The Breda 79S was unusual amongst the Società Italiana Ernesto Breda's products in the late 1930s in that it was a civil machine rather than a military one.  It was a single-engined high-wing monoplane with a rather well equipped cabin for four.  The wings were joined to the upper fuselage longeron and braced with streamlined vee struts to the lower longeron in the conventional way.  They had almost straight leading edges with taper on the trailing edges and rounded tips.  Trailing edge flaps and leading edge slots were interconnected.  The tailplane was mounted at mid-fuselage height and was braced to the rounded fin, which carried a wide chord and unbalanced rudder.  These tail surfaces were fabric over wooden frames.

The aircraft was powered by a 200 hp (149 kW) Alfa-Romeo 115 six-cylinder inverted inline engine, neatly cowled but giving the Breda 79 a long-nosed look.  The engine drove a two-bladed propeller.  The fuselage was a fabric-covered welded steel structure, faired to an oval cross section.    Behind the engine and under the wings was the cabin with four seats in two rows of two. Glazing was generous, including an openable roof window, and the cabin was both thermally and acoustically insulated with controllable ventilation. The seats were deep enough to allow everyone to wear a parachute backpack  and in an emergency the pilot could open both the wide side doors and the roof light with a single lever.    The pilot's position was instrumented, and the aircraft lit, for night flying.   The divided undercarriage had widely splayed legs attached at the bottom of the wing bracing struts, carrying semi-spatted wheels (closely streamlined but with the outer side of the wheel visible).

The first Breda 79, c/n 78001 was registered as I-ABFU on 20 April 1936 together with a second example, I-ABFT c/n 78002 but it is not known when they first flew. Records are sketchy, but three seem to have been flown and used by the Ministero Aeronautica.

PT-109 (video game). PT-109 is a naval simulation video game developed by Digital Illusions and Spectrum HoloByte in 1987 for the Macintosh and MS-DOS. This game is roughly based on the events involving the Motor Torpedo Boat PT-109.

Gameplay
PT-109 is a torpedo-boat simulation game which starts in the practice-tactics mode to teach new players how to operate the boat, fire torpedoes, read radar on different displays, using the engine muffler to approach quietly, operating smoke screens, and locate other weaponry. Players also learn about the history of the ship, because some of the patrol boats were only available at specific stages during World War II. The game has four levels of difficulty, and it also gives the player the ability to send radio messages to the base to request air or ship support, an automatic pilot feature, and assignment of patrols.

Development
A remake of PT-109, called PT Boat Simulator, was released for DOS PC in 1994.

Reception
A Computer Gaming World reviewer in 1988 called PT-109 "a remarkable achievement", but stated that he no longer played the game because he had played all of the preprogrammed patrols several times and knew what would happen. He recommended using the practice mode to become familiar with the game, instead of the lowest difficulty level, to maximize its lifetime. 1991 and 1993 surveys of strategy and war games gave it two and a half stars out of five. In 1988, Dragon gave the Macintosh version of the game 4 out of 5 stars. They in 1989 gave the MS-DOS version 4½ out of 5 stars. The Palm Beach Post in 1988 approved of the Macintosh version's improved graphics compared to Gato, but reported that campaign enemies did not correctly react to the player.

Esso Northumbria. The Esso Northumbria was the first of a series of Very Large Crude Carrier ships, built by Swan Hunter at Wallsend on Tyneside, in 1969. When launched on 2 May 1969 by Princess Anne it was the largest vessel to have been built in Britain at that time.

The ship was designed to carry crude oil from the Persian Gulf, and its large design was a result of the Six Day War, which had resulted in the closing of the Suez Canal. The ship was single-hulled and was designed with relatively limited knowledge of the behaviours of such large structures at sea, being generally a straightforward scaling-up of a smaller design. It was also built to a fixed-price contract at a time when rampant inflation was occurring in Britain. This led to many attempts to cut costs; Swan Hunter ultimately made a loss on the contract. Final cost of the ship was £6.5 million.

The ship was plagued with problems both with its fittings and more seriously, with cracking of the hull under stress. It needed many repairs in its short working lifetime and this, together with fears of a major spill, prompted its retirement in 1982 after only 12 years in service. The ship was broken up at Kaohsiung, Taiwan. A similar fate befell its sister ship, the Esso Hibernia, also built on Tyneside and launched in 1970.

In popular culture

 In the 1971 feature film Get Carter starring Michael Caine, the Esso Hibernia appeared in the background of a shootout scene at the ferry terminal.
 In 2019, The Dreadnoughts, a Canadian folk punk band, released "Roll Northumbria," a song which details an alternate version of the Northumbria's short lifespan, in which the cracks in the hull cause an oil spill.

Soldier Integrated Protective Ensemble. The Soldier Integrated Protective Ensemble (SIPE) program is the initial step in developing an integrated modular clothing and equipment system for combat ground troops of the United States Army.

Testing
The field portion of the Soldier Integrated Protective Ensemble (SIPE) Advanced Technology Demonstration (ATD) was conducted at Fort Moore, Georgia, from September through November 1992. Individual task performance-data were collected by the Test and Experimentation Command (TEXCOM) Close Combat Test Directorate, and collective task performance data were assessed by personnel from the U.S. Army Infantry School (USAIS). Soldier impressions on and suggestions for the SIPE equipment were collected. As a technical advisory service to the SIPE ATD, U.S. Army Research Institute for the Behavioral and Social Sciences (ARI) personnel collected this data. The SIPE, configured as a head-to-toe individual fighting system, demonstrated considerable potential for enhanced soldier capabilities and operational effectiveness. However, the equipment, only prototype in nature, affected test soldier performance and attitude. The enhanced communications capability and thermal sight on the rifle, as well as some items of clothing, were deemed very acceptable; other items were rejected or insufficiently tested. Further testing would be beneficial.

Psychological effect
This system will increase lethality, mobility, survivability, command and control and overall protection of the troops. This environmental chamber study compared physiological responses of volunteers exercising in MOPP 0, MOPP 1, and MOPP 4 with equivalent SIPE configurations, including SIPE 4 with and without ambient air microclimate cooling (MCC). Responses to all uniforms were compared over 100 minutes of continuous treadmill walking at 30.0 deg C, 50% rh. Responses to MOPP 4 and SIPE 4 with no cooling were also compared over 100 minutes at 18.5 deg C, 50% rh. Responses to MOPP 4 and SIPE 4 MCC were compared over four hours of intermittent work-rest cycles at 30.0 deg C, .50% rh. There were no differences between MOPP 0 and SIPE 0, MOPP 1 and SIPE 1, and MOPP 4 and SIPE 4 with no cooling (in both environments) . Core temperature, skin temperature, heat storage, and heart rate were lower in SIPE 4 MCC than in MOPP 4; while evaporative cooling was greater in SIPE 4 MCC than in MOPP 4. Three volunteers completed the 4-hour tests in SIPE 4 MCC with similar advantageous trends apparent from the cooling. It is concluded that the SIPE clothing did not increase thermal strain compared to equivalent MOPP levels, and MCC, (although increasing uniform weight by approximately 10 kg) reduced thermal strain at 30.0 deg Celsius.

ExoCarta. ExoCarta is a manually curated database of exosomal proteins, RNA and lipids.

Exosomes are cell-derived vesicles that are present in many and perhaps all biological fluids, including blood, urine, and cultured medium of cell cultures. The reported diameter of exosomes is between 30 and 100 nm, which is larger than LDL, but much smaller than for example, red blood cells. Exosomes are either released from the cell when multivesicular bodies fuse with the plasma membrane or they are released directly from the plasma membrane. It is becoming increasingly clear that exosomes have specialized functions and play a key role in, for example, coagulation, intercellular signaling, and waste management. Consequently, there is a growing interest in the clinical applications of exosomes. Exosomes can potentially be used for prognosis, therapy, and biomarkers for health and disease.

Bioinformatics analysis of exosomes
Exosomes contain RNA, proteins, lipids and metabolites that is reflective of the cell type of origin. As exosomes contain numerous bioactive molecules, including proteins, nucleic acids, lipids, sugars, and related conjugates, large scale analysis including proteomics and transcriptomics is often performed. Currently, to analyse these data, non-commercial tools such as FunRich can be used to identify over-represented groups of molecules.

Schoonschip. Schoonschip was one of the first computer algebra systems, developed in 1963 by Martinus J. G. Veltman, for use in particle physics.

"Schoonschip" refers to the Dutch expression "schoon schip maken": to make a clean sweep, to clean/clear things up (literally: to make the ship clean). The name was chosen "among others to annoy everybody, who could not speak Dutch". 

Veltman initially developed the program to compute the quadrupole moment of the W boson, the computation of which involved "a monstrous expression involving in the order of 50,000 terms in intermediate stages"   

The initial version, dating to December 1963, ran on an IBM 7094 mainframe.  In 1966 it was ported to the CDC 6600 mainframe, and later to most of the rest of Control Data's CDC line.  In 1983 it was ported to the Motorola 68000 microprocessor, allowing its use on a number of 68000-based systems running variants of Unix.

FORM can be regarded, in a sense, as the successor to Schoonschip.

Contacts with Veltman about Schoonschip have been important for Stephen Wolfram in building Mathematica.

W.W.S.2 Żaba. The WWS-2 Żaba (Frog) was a single-seat training glider designed and built in Poland from  1937.

Development 
Czerwiński improved the design of the CWJ-bis, with reduced structure weight and changes to the flying control surfaces, to improve performance and manoeuvrability. The W.W.S. 2 followed the primary trainer concept with a skeletal fuselage wire-braced to a simple fabric covered wing, supported by two struts each side, and tail unit. The completely open seating area followed the theory of the day, that called for the student pilot to feel the wind on his/her body to fully appreciate the movements of the aircraft in response to control movements and atmospheric changes, such as gusts, turbulence or thermals. One W.W.S. 2 survived the war, to fly again, and was retired to the Kraków Aviation Museum in 1950.

Production of the  Żaba at  the W.W.S. Commenced in 1937, with 60-70 built before the outbreak of World War II. The  Żaba II (Żaba-bis) was produced at the Lwow aviation workshops (L.W.L.), with approx 150 built, 20 for export.

Variants 
 WWS-2 Żaba – production aircraft from W.W.S. From 1937.
 WWS-2-bis Żaba II – improved version with reduced weight and improved controls built by the Lwow Aviation Workshops (L.W.L.).
 CWA Wren – A  WWS-2 Żaba built in Canada, after WWII, by Wacław Czerwiński.

The Magic Cauldron (essay). "The Magic Cauldron" is an essay by Eric S. Raymond on the open-source economic model. It can be read freely online and was published in his 1999 book, The Cathedral and the Bazaar.

Contents
The essay analyzes the economic models that Raymond believes can sustain an open-source project in four steps:
 It first analyzes what the author sees as classical myths about the cost refund in software development and tries to present a game-theory based model of the supposed stability of open-source cooperation.
 Secondly, it presents nine theoretical models that would work for sustainable open-source development: two non-profit, seven for-profit.
 Thirdly it states a theory to decide when it is economically interesting for software to remain closed.
 Finally, it examines some mechanisms that, according to Raymond, the market invented to fund for-profit open-source development (like patronage system and task markets).

W.W.S.3 Delfin. The WWS-3 Delphin (Dolphin) was a single-seat glider designed and built in Poland from  1936.

Development 
To provide a higher performance glider, to complement the W.W.S.1 Salamandra and W.W.S.2 Żaba, Wacław Czerwiński designed an all wood glider with smooth lines derived from wind tunnel tests at the Lwów Technical University. With a stiff structure optimised for higher speeds the W.W.S.3 had pleasant flying characteristics. The first prototype was built with two alternative tailplanes, one conventional with separate elevator, the other an all-flying surface, both of which were evaluated in airworthiness trials at the I.B.T.L. (Instytut Badań Technicznych Lotnictwa – Institute of Aviation Technical Research) during 1937. Production aircraft were produced at W.W.S and at L.W.L.(Lwówskie Warsztaty Lotnicze – Lwów Aviation Workshops) with the all-flying tail for pitch control.

The cantilever gull wings were constructed as a divided pair, with diagonal supplementary spars and plywood skinned leading edge D torsion box. The fuselage was constructed as a semi-monocoque shell, with integral fin carrying the rudder and all-flying tailplane. A pneumatically sprung nose skid formed the undercarriage.

Production continued until the outbreak of World War II, with most aircraft being destroyed except for examples confiscated by the German and Soviet authorities. One example taken by German forces was left behind in Denmark at the end of the war, and refurbished for the Stamgruppen Gliding Club (regn OY-DYX), where it flew for several years.
