Designers Choice. The Designers Choice is an American sailing dinghy that was designed by Sparkman & Stephens as a sail training and racing boat and first built in 1978. It was Sparkman & Stephens' design #2349.

The Designers Choice was later developed into the Shadow, by making the cockpit longer and deeper and adding internal seating.

Production
The design was built by Howmar Boats in the United States starting in 1978. A total of 1,500 boats were produced, but the company went out of business in 1983 and the boat went out of production at that time.

Design
The Designers Choice is a recreational sailboat, built predominantly of fiberglass. The hull design is flat aft, so the boat will plane. It has a fractional sloop rig with anodized aluminum spars and a loose-footed mainsail. The hull has a slightly raked stem, a vertical transom, a transom-hung, kick-up rudder controlled by a tiller and a retractable centerboard. The forward part of the boat is open, without a foredeck. The aft deck includes a small stowage locker. The cockpit is self-draining. The boat displaces .

The boat has a draft of  with the centerboard extended and  with it retracted, allowing beaching or ground transportation on a trailer.

For sailing the design is equipped with an outhaul, boom vang, a Cunningham and a jib window. It is also fitted with foam flotation for buoyancy, hiking straps and may also be optionally equipped with a spinnaker for sailing downwind.

The boat may be fitted with a small outboard motor for docking and maneuvering.

The design has a Portsmouth Yardstick racing average handicap of 101.3 and is raced with a maximum crew weight of .

Operational history
In a 1994 review Richard Sherwood wrote, "this is a combination boat, meant for training, racing, or general sailing. The Designers Choice has curved sections forward and is relatively dry. With flat surfaces aft, she planes."

Enrico Bianchini. Enrico Bianchini (30 July 1903 – 24 October 1971) was an Italian civil engineer. His work was part of the architecture event in the art competition at the 1936 Summer Olympics.

Life and career
Born in Robbio, in the province of Pavia, on 30 July 1903, Bianchini completed his early studies in Massa. He initially attended the art history course at the University of Pisa (1920–1922) before enrolling in the School of Engineering in Rome, where he graduated in civil engineering on 22 April 1926. From August of that year, he worked with the engineering firm Poggi, Gaudenzi & C., which later hired him as a designer and site manager in 1927, a role he held until 1938. During this time, he oversaw numerous projects, including industrial buildings, cinemas, and bridges.

Between 1929 and 1931, he collaborated on the construction of artistic features of the A11 Highway with the Saverio Parisi firm.

Bianchini also partnered with architect Raffaello Fagnoni for nearly two decades. Together, they drafted urban plans for Pisa, Faenza, and Asti; contributed to the Mussolini Stadium in Turin and the municipal stadium in Lucca; restored historical buildings; and designed public works such as Carabinieri barracks and railway stations. Bianchini focused on reinforced concrete structures, such as the University of Trieste building and various Fascist-era projects in Florence and other cities.

After 1938, he became technical director of the SACIP company. Post-World War II, Bianchini led the construction of industrial, residential, and civic projects, including factories, stadiums, public housing, and power plants across Tuscany. He also worked independently on villas and residential complexes in the region.

Moelva (Agder). Moelva (old spelling: Maa Elv) is a river in the municipalities of Birkenes and Lillesand in Agder, Norway.  It originates from a hill south of Tveide in Birkenes and empties into the Tingsakerfjord, east of the town of Lillesand.  Large parts of the disused, former railway Lillesand-Flaksvand Line followed the river bank.

An old stone bridge is still located by Helvetesfossen. It was restored by the Norwegian Public Roads Administration in 1993.

Hydropower  
The hydropower company Lillesand Elektrisitetsverk was started as a private company in 1916. There were dams in all tributaries to Moelva, dam at Helvetesfossen and pipeline down to the power station at Tingsaker, that had a turbine of 150 hp, a generator of 125 kW and an oil transformer of 7 kW.  The power plant was sold and closed in 1970.

Fishing 
Moelva is a sea trout leader in the lower part. It is Lillesand municipality that has been responsible for both the preparation and clearing of the riverbed and built a threshold dam in the lower part of the river. The sea trout population has recovered after a decline due to pollution.

Carbon dioxide recorder. A carbon dioxide recorder (or CO2 recorder) is a machine that can record the level of carbon dioxide at different times. It is more sophisticated than a carbon dioxide detector which only has to indicate the presence of carbon dioxide. There are three main types of carbon dioxide recorder: chemical, physical, and electrical.

Mechanism

Chemical
The chemical carbon dioxide recorder, sucks the gas through a chemical that absorbs carbon dioxide. They include the Simmance combustion recorder; Hays automatic CO2 recorder, and electroflo CO2 recorder.

The Arndt carbon dioxide recorder used a potassium hydroxide solution to absorb carbon dioxide.

The Uehling recorder uses the chemical, sodium hydroxide to absorb the carbon dioxide, and measures the change in volume of the gas.

Physical
The physical carbon dioxide recorder, includes Webster CO2 recorder. The Remarex carbon dioxide recorder uses vanes spinning in the gas under test and the air.

Electrical
Electrical recorders use a thermal conductivity method, where the resistance of a heated wire is measured.

Form
Carbon dioxide recorders can be handheld, or wall mount. They can have an audible or light indicator alarm if level is too high. Units can also measure humidity and temperature.

Application
Carbon dioxide recorders have been used in schools and hospitals to determine whether enough fresh air is being circulated. A carbon dioxide recorder can be used to measure the composition of flue gas to check if combustion is at its most efficient. In agriculture, they can be used to measure levels of carbon dioxide in greenhouses, where the levels are deliberately elevated.

Tyndall's bar breaker. Tyndall's bar breaker is a physical demonstration experiment to demonstrate the forces created by thermal expansion and shrinkage. It was demonstrated 1867 by the Irish scientist John Tyndall in his Christmas lectures for a "juvenile auditory".

Setup 
The bar breaker experiment comprises a very rigid frame (d) and a massive connecting rod (b). The rod is held on one side by a cast iron bar (c) that is going to be broken in the experiment and, at the other end, by a nut (a) that is used to compensate the thermal expansion.

Procedure
During the experiment the steel rod (b) is heated with a flame (e) up to red heat temperature. During the heating phase the thermal expansion of the rod (b) is compensated by tightly fastening the nut (a). Taking away the flame starts the cooling phase. Typically the bar (c) breaks within a few minutes with a loud bang or it is at least deformed significantly.

OroraTech. OroraTech is a German aerospace start-up company providing wildfire monitoring by employing nanosatellites. It was founded in 2018 as a university spin-off at the Technical University of Munich (TUM). The headquarters are in Munich, Germany. In June 2023, OroraTech joined the Copernicus Programme of the European Space Agency.

History 

OroraTech's key idea had been developed during the MOVE-II CubeSat project and WARR at the TUM. Starting as a spin-off in January 2017, the company was incorporated as Orbital Oracle Technologies GmbH (short: OroraTech) in September 2018. Since OroraTech's technology is based on academic research at the TUM, TUM professors Ulrich Walter, a former astronaut, and Alexander W. Koch act as advisors to the company.

Technology 

Wildfire detection using infrared sensors in space had been proposed as a technology since the 1990s. Technological advances, notably sunk space launch cost, enabled non-state actors to enter the market. As such, OroraTech operates a software platform for the detection and monitoring of wildfires based on measuring thermal-infrared radiation from space. The company is using data from existing satellites and develops their own constellation of 3-U CubeSats with thermal-infrared cameras to further improve temporal and spatial resolution of fire detection.

The software platform generates various overlays on base maps to visualize fire risk and fire detections. At the current stage, the platform uses data from twelve satellites in polar and geostationary orbits, including such by NASA, ESA, and EUMETSAT. In early 2020, the platform had around 100 active users.

The satellite technology is based on research from the MOVE-II project at the Chair of Astronautics (LRT) at the TUM. During the project, a 1-Unit CubeSat was launched with SpaceX in December 2018. OroraTech's first nanosatellite, based on the original CubeSat, was developed to reach 10 cm x 10 cm x 34 cm in size, weighing around 1.2 kg, and it was launched on 13 January 2022 as part of SpaceX's Transporter-3 rideshare mission. The satellite features an uncooled thermal-infrared imager for space applications, and GPU-accelerated on-orbit processing to reduce downlink latency and bandwidth for quicker wildfire alert dissemination, making it particularly efficient in tackling the issue of detecting wildfires in late afternoon images.

As of June 2022, the company plans to put its next eight satellites into orbit by the end of 2023, aiming for a detection time of 30 minutes. A second satellite, once again hosted on a Lemur-2 cubesat platform, was launched on 12 June 2023 on a Falcon 9 Block 5 rocket as part of SpaceX Transporter-8 rideshare mission.

Field application 

The technology is used by Wildfire Services in British Columbia (Canada) and New South Wales (Australia) for wildfire detection and wildfire suppression. International media used images from OroraTech's wildfire service for coverage of the 2020 wildfire season in California, 
Oregon, British Columbia, and Siberia.

Alhena (AKL-38). Alhena (AKL-38) was a Design 381 (Vessel, Supply, Diesel, Steel, 177') built for the United States Army as FS-257. The Army vessel was U.S. Coast Guard crewed, serving in the  Southwest Pacific during World War II.

The ship was acquired by the United States Navy 12 December 1951, named Alhena and loaned to the Republic of Korea the same day. She was the second ship of the United States Navy to bear the name but had no U.S. Navy service under the name. The ship was returned from loan January 1960, struck the next month and sold for scrap in June 1960.

Ship history

U.S. Army (1944–1951)
FS-257 was laid down in 1944 by Wheeler Shipbuilding, Whitestone, New York, yard number 71, for delivery to the United States Army. On 24 June 1944 the U.S.  Coast Guard manned freighter was commissioned at New York with  Lt. G. P. Hammond, USCG as commanding officer. On 26 June FS-257 departed for the Southwest Pacific operating there through the landings at Leyte. In July 1945 the ship ran aground in the general vicinity of Maripipi island and was assisted off the beach by FS-406.

U.S. Navy/Republic of Korea service (1951–1960)
On 12 December 1951, during the Korean War, FS-257 was acquired by the United States Navy, named Alhena, after the third largest object in the Gemini constellation, and on the same day loaned to Republic of Korea for service with the Republic of Korea Navy. She left Korean naval service in January 1960, and was returned to U.S. custody shortly thereafter. On 1 February 1960, she was struck from the Naval Register.

Fate
She was sold for scrap to Hong Kong Rolling Mills, Ltd. in June 1960. The ship is listed among a registry of naval vessels that contained asbestos in her construction.
