Diiodoacetylene. Diiodoacetylene is the organoiodine compound with the formula C2I2.  It is a white, volatile solid that dissolves in organic solvents.  It is prepared by iodination of trimethylsilylacetylene.  Although samples explode above 80 °C, diiodoacetylene is the most readily handled of the dihaloacetylenes. Dichloroacetylene, for example, is more volatile and more explosive.  As confirmed by X-ray crystallography, diiodoacetylene is linear.  It is however a shock, heat and friction sensitive compound. Like other haloalkynes, diiodoacetylene is a strong halogen bond donor.

Indian locomotive class ZDM-2. The Indian locomotive class ZDM-2 is a series of narrow gauge diesel-hydraulic locomotives built for Indian Railways by the German company Maschinenbau Kiel. In the 1980s and 1990s, several of the type were fitted with KPC engines, these were reclassified as the ZDM-2R.

History 
The ZDM-2 class was designed and manufactured by Maschinenbau Kiel (MaK). The type was specially developed for the Indian 762 mm railway lines. Locomotive No 600488 was tested on the Kreisbahn Osterode-Kreiensen 750 mm gauge railway line before delivery. The class was initially used on the Kalka–Shimla Railway and the Kangra Valley Railway, then later in Nagpur. On the Kalka-Shimla line, ten ZDM-2 locomotives partly replaced the ageing steam locomotives and partly the inefficient and failure-prone ZDM-1 diesel locomotives for passenger transport. On the Kalka–Shimla line, ZDM-1 locomotives pulled only three passenger coaches, while ZDM-2 locomotives often pulled seven. The ZDM-2 and ZDM-1 locomotives that remained on the line were completely replaced by ten ZDM-3 locomotives delivered between 1970 and 1972, the former being transferred to the South Eastern Railway in 1971–1972 and the latter to the Matheran Hill Railway in 1976. The ZDM-2s were fitted with a hydraulic transmission of the Indian "Suri" type, which proved to be highly failure-prone. The series was equipped with the Maybach "MD 435" diesel engine. On the first ten units these operated at the speed of 1400 min⁻¹ for a power output of , while on the latter fifteen at 1700 min⁻¹ for a power output of .

Several members of the type were modified in the 1980s and 1990s; they were fitted with KPC hydraulic transmissions and MaK diesel engines.

Cotton maturity. Cotton maturity is a physical testing parameter of cotton fiber properties testing. It is quantified by the degree of cell wall thickening relative to its  perimeter. The maturity of individual cotton fiber is an essential aspect of the cotton classing regarding the aesthetics such as appearance, dye-uptake, etc. High volume instrument (HVI) can test cotton maturity like many other fiber properties, including length, uniformity, micronaire/fineness, strength, color, etc.

Major impact 
Cotton maturity of fibers largely depends upon the growing conditions. Cotton maturity is measured as the relative wall thickness (i.e., the area of the cell wall to that of a circle with the same perimeter as the fiber, or the ratio of the cell wall thickness to the overall ‘diameter’ of the fiber). Hence the thickness of the wall infers the extent of the maturity of cotton fibers. Cotton fibers are trichome cells composed primarily of cellulose. Mature fibers have more cellulose and a greater degree of cell wall thickening. The significant impact of immature fiber is on the finished appearance. The MIC values of immature fibers determine the processing and performance of cotton. The commonly caused defects by immature cotton are related to yarn and fabric appearance such as poor dyeing uptake, dead fibers, neps formation, and barre also (if the batch to batch maturity ratio is different).

Measurements 
Cotton classification, or classing, is the process of classifying cotton based on its grade, staple length, and micronaire. Micronaire is a measure of cotton maturity. Maturity of cotton fibers is measured with single fiber measurement test or by double compression air flow test. It is expressed in percentage or maturity ratio.

Micronaire 
Cotton's simple Micronaire value is determined by both the fineness of the fibres as well as their maturity. Micronaire values or reading represents the fineness of the cotton fiber. For example a  preferred micronaire range is 3.7 to 4.2. Upland cotton is coarser than Gossypium barbadense (Pima cotton).

ČD Class 700. The ČD Class 700 (Formerly ČSD Class T 211.0) is a two-axle diesel–mechanical locomotive. It was designed for shunting in depots, stations and sidings.

In depots, these small locomotives were used for moving and hauling locomotives during repairs (when the locomotives could not move under their own power) and in places where it was necessary to move electric locomotives without overhead lines (in roundhouses, on turntables and in engine sheds where space were limited and therefore the small overall length over the bumpers often played an important role).

The locomotives were manufactured by ČKD between 1957 and 1962. A total of 824 were produced for the Czechoslovak State Railways, various Czechoslovak industrial enterprises and for export to the Soviet Union, the GDR, China, Romania, Albania and Bulgaria.

Technical details

Engine
They were fitted with a Tatra 111 A engine. The engine is an air cooled, V12, fuel injected, four-stroke diesel. It has an output of 121 kW and a displacement of 14.823 litres. The cylinder bore is 110 mm and the piston stroke is 130 mm. Each cylinder has one intake and one exhaust valve, an injection nozzle and a piston equipped with five piston rings. The engine has three camshafts. One drives the intake valves and the other two drives the exhaust valves. The idle speed is set to 720 rpm, the nominal (maximum) speed to 1600 rpm.

Transmission
The locomotives were fitted with a ČKD M 150-4 mechanical, four-speed transmission which is used to transfer power from the engine to the two driven wheelsets.

Blue Water 24. The Blue Water 24 is an American trailerable sailboat that was designed by Thomas C. Gillmer as a blue water cruiser and first built in 1961.

The design was developed into the Passage 24 in 1979, using a new coach house on the existing hull design.

Production
The Blue Water 24 design was a commission by Blue Water Boats who had it built by Holden Laminates in the United States starting in 1961, but it is now out of production.

Design
The Blue Water 24 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig and can also be cutter rigged. The hull has a raked stem, an angled transom, a keel-mounted rudder controlled by a tiller and a fixed long keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel.

The boat is fitted with a Universal Atomic 4  gasoline engine for docking and maneuvering. The fuel tank holds  and the fresh water tank has a capacity of .

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two quarter berths in the main cabin. The galley is located on the port side just aft of the bow cabin. The head is located opposite the galley on the starboard side. Cabin headroom is .

For sailing the design is equipped with a large headsail genoa and a 3/4 jib, that can be used in any combinations.

The design has a hull speed of .

Operational history
In a 2010 review Steve Henkel wrote, "best features: The broad bowsprit with a pulpit extended over it gives good purchase for dealing with an anchor We also like the big portlights in the doghouse, the better to check out one’s neighbors in a cozy anchorage. Worst features: ... Of the four comp[etitor]s listed below, the Blue Water 24 has by far the least enticing accommodations plan. For example, there appears to be no dining table, nor any place to put one. And the enclosed head compartment is located smack dab amidships, leaving only an 18-inch space to stand in front of the galley."

Jacob Bell (pilot boat). The Jacob Bell was a 19th century Sandy Hook pilot boat built by the shipbuilder Jacob Bell for a group of New York Pilots in 1840. She was named in honor of the shipbuilder Jacob Bell, who was a partner in the Brown & Bell firm. After fourteen years of service she went ashore in a gale off Sandy Hook in 1854.

Construction and service 

On 22 January 1840, the pilot boat, Jacob Bell, was launched from the Brown & Bell shipyard, on the East River. She was built by shipbuilder Jacob Bell. The Bell, was named in honor of the shipbuilder Jacob Bell, who was a partner in the Brown & Bell firm. The launch was witnessed by a large party of ladies and gentlemen. She was owned by a company of New York pilots, including James Britton, Mitchell Eleock, Halston, and others. Her dimensions were 71 ft. in length; 19 ft. breadth of beam; 8 ft. in depth; and 84-tons burthen. Her cost was $8,000. She was expected to beat the famous Washington, which was known for her speed. The boat number "4" was painted as a large number on the mainsail.

In 1840, there were only eight New York pilot boats. They were the Phantom, No. 1; Washington, No. 2; New York No. 3; Jacob Bell, No. 4; Blossom, No. 5; T. H. Smith, No. 6; John E. Davidson, No. 7; and the Virginia, No. 8.

On 14 December 1840, Wm. H. Rolston, of the pilot boat Jacob Bell, along with other pilots from the port of New York, stated that they had never been employed by J. D. Stevenson and no compensation has been offered or demanded.

On March 15, 1844, an Admiral of the New York Clipper Boats thanked the pilots of the Charlotte Ann, Jacob Bell, Blossom, and Joseph N. Lord for their service and for the fact that they have often been boarded two hundred miles at sea by New York pilots.

On February 15, 1848, pilot-boat Jacob Bell, off Egg Harbor City, New Jersey passed a brig that was capsized. The wreck was also seen by the pilot-boat Washington, the previous day.

End of service

After fourteen years of service, the Jacob Bell, went ashore in a gale at the Sandy Hook beach on February 16, 1854 with a loss of all the crew. She was filled with water. She lay on the beach through February and March and was reported in bad condition. By April 13, the Bell was taken off the beach and returned to the city.

Hermann Paucksch. Hermann Johann Gottlieb Paucksch (13 April 1816, Landsberg an der Warthe - 5 March 1899, Landsberg an der Warthe) was a German mechanical engineering contractor and manufacturer.

Biography 
He was born to Johann Gottlieb Paucksch, a Master Turner, and his wife Dorothea, née Jabelt. As he grew up, he learned the trade of a brass worker. While still young, he married and had a large family. In 1843, he and his father started a mechanical engineering workshop. In 1863, he took a partner (Johann Heinrich Freund, otherwise unknown), becoming "Paucksch & Freund" and producing steam boilers. 

In 1874, anticipating passage of the "" (social legislation) proposed by Otto von Bismarck, he set up a pension and disability fund for his employees and provided it with an initial fund of 5,000 Thalers. Each employee then made an annual contribution of two Thalers. Three years later, he had a small castle built just outside Landsberg, known as the "Villa Paucksch". It later served briefly as a hospital, then was home to the "Grodzki House of Culture" until 2014. It has been named an "object of cultural heritage" by the Polish government.

In 1884, his eldest son became Technical Director. Four years later, the company was converted to a stock corporation. In 1893, there was a major fire at the factory and he retired, leaving the company's operation to his sons. At its height, it produced steam boilers, steam engines, ship steam engines, gas engines, diesel engines, turbines, transmissions, mash and water pumps, steam cutting mills, complete alcohol distilleries and drying systems. 

He was a member of the Landsberg City Parliament, under the Prussian three-class franchise, and was made an honorary citizen. In 1896 he showed his gratitude to the city by donating a fountain, created by Cuno von Uechtritz-Steinkirch, one of the sculptors working on the Siegesallee who, in 1901, would also create a monument to Paucksch on the main city bridge. Both works were melted down for use as war materiel during World War II. In 1997, a replica of the fountain was created, with donations from former German residents. The recreation was carried out by the Polish sculptor, .

Pierre Waché. Pierre Waché (born 10 December 1974) is a French Formula One engineer. He is the technical director at the Red Bull Racing Formula One team.

Career 
Waché earned a doctorate in fluid dynamics from the National Polytechnic Institute of Lorraine, specialising in bio-mechanical engineering. After graduating, he began working in 2001 for the global tyre manufacturer Michelin in their Formula One programme, and was an engineer that was responsible for the interaction between tyres and track conditions for Formula One cars. At the end of 2006, Michelin left Formula One as a tire supplier, which resulted in Waché being recruited by BMW Sauber as a performance engineer, working with tyres and suspension.

In 2009, BMW announced that it would leave Formula One, which resulted in Waché replacing Loïc Serra as the head of vehicle performance for Sauber. In 2013, he moved to Red Bull Racing and become the chief engineer with a focus on vehicle performance; six months later, he was appointed to succeed Mark Ellis as performance director. In 2018, he took on the role of technical director being responsible for the design and production of the car, second only to Adrian Newey.

Vought V-326. The Vought V-326 (alternatively Vought-Sikorsky VS-326) was an American experimental aircraft used by Pratt & Whitney as a high altitude engine test bed.

Design and development 
Vought began work on the V-326 in 1941 at the request of Pratt & Whitney.  Designed as a test bed for the R-4360 Wasp Major radial engine, the aircraft was based on the XTBU-1 Sea Wolf and used components from the F4U Corsair.  The V-326 was a low-wing monoplane with a pressurized two-seat cockpit.  Its main landing gear rotated 90 degrees and retracted rearward into the wings.  In the rear fuselage was a compartment for ballast.  The engine's carburetor was fed by a scoop situated ahead of the vertical stabilizer.

Operational history 
The V-326 made its first flight on June 18, 1943 at the hands of P&W chief test pilot A. Lewis McClain.  Harold B. Archer flew most subsequent flights, with pressurization troubles keeping most flights below .

The second aircraft, the V-326A, made its first and only flight on August 30, 1944.  It subsequently underwent modifications, though they were not completed as the need for the aircraft faded.  Both aircraft were scrapped in 1946, the V-326 having only 111 hours logged.

Variants 
V-326
First aircraft with a deep cowling enclosing the supercharger and a three-bladed propeller.

V-326A
Second aircraft with a tight cowling, intakes under the wings feeding the twin superchargers, and a four-bladed propeller.
