Dodge Airflow truck. The Dodge Airflow truck was a special request model truck that Dodge introduced in late 1934 and available through 1940. It used styling cues from Chrysler Airflow cars and the Divco 1937 Model-B delivery vans. Most of the 265 units produced were fitted with streamlined tank truck bodies, and were used by major oil companies, like Texaco, Socony-Vacuum Oil Company and Esso.

History 
Airflow trucks were based on standard Dodge models, so from an engineering point of view they were rather conventional, despite their striking look. Five model names were assigned successively to the Airflow production; namely K-52, LM-70, LM-71, RX-70 and RX-71.

Garwood Industries and Heil Co. of Milwaukee, Wis, among others, were the producers of the tank bodies; while the bodies of two beer trucks for Joseph Schlitz Brewing Company were built by H. Barkow Co., of Milwaukee.

On display 
A restored 1940 Dodge RX70 Airflow Texaco tanker truck is on display at the Transport World museum in Invercargill, New Zealand. This truck is believed to be the only one of its type in the world that can still be driven. It was a highlight of the 2017 Southland Truck Parade held in Invercargill in October 2017.

Other streamlined tanker trucks
By the same years other streamlined tanker bodies were fitted to more conventional chassis-cabs of other truck makers, like Mack, International and Diamond T.

Specially unconventional and noteworthy were the impressive Texaco's Diamond T Doodlebug tankers, designed by the futuristic industrial designer Norman Bel Geddes. They featured a Heil low profile body and used a Hercules six-cylinder engine mounted in the rear and a large radiator behind it. Air pressure actuated the four-speed gearbox and clutch, using the same pneumatic system for braking. A compound-curved windshield and curved side glass were also noticeable features.

In Australia the Socony Vacuum Oil Company owned several remarkable streamlined Reo Speed Tankers. These trucks were built on Reo Cab over-engine three-Ton chassis. Bodies were built by Martin & King Coachbuilders in Melbourne.

Albrecht Tischbein. Johann Heinrich Albrecht Tischbein (15 November 1803, Sternberg - 22 March 1881,  Rostock) was a German engineer and shipbuilder; one of the designers of the first German iron screw steamers.

Biography 
His father was the painter and art teacher, August Albrecht Christian Tischbein. His youth was spent in the port of Rostock, where he developed his interest in ships. With help from  his cousin, the naval officer and engineer Gerhard Moritz Roentgen, he was able to train as an engineer in Seraing with John Cockerill. In 1821, he completed his course and worked in Rotterdam as a mechanical engineer, building steamships. In 1837, he constructed a wooden steamship for the  in Magdeburg. From 1838 to 1849, he was the company's Technical Director. Under his leadership, the company produced 33 ships; 14 of iron.

1850 saw the creation of the "Rostocker Dampfschiff-Fahrt-Gesellschaft", with the goal of creating two iron steamships to provide regular service between Rostock and Saint Petersburg. After studying the situation there, Tischbein returned to Rostock and, together with the master shipbuilder Wilhelm Zeltz (1814-1864), established a shipyard and machine works. Their first iron ship, the "Grand Duke Friedrich Franz", was completed in 1851. It had 60 hp and could reach a speed of 9.25 knots. After only four years of service on the route, it was sold for financial reasons. Their second iron ship, the "Grand Duke Constantine", was completed in 1852. After that, Zeltz left to build wooden sailing ships. Tischbein remained as the Director until 1876. After several mergers and a buyout, his company became part of the "Actien-Gesellschaft Neptun" in 1890. The firm is still in business under the name Neptun Werft GmbH.

In addition to his ships, he also designed gas processing plants and steam pumps.

Offpiste Discovery. The Offpiste Discovery is a series of British high-wing, single or two-place, hang gliders that were designed by Bill Pain and produced by Colin Lark's company Offpiste Aviation Limited (Off The Beaten Track) of Dursley, Gloucestershire. Now out of production, when it was available the series of aircraft were supplied complete and ready-to-fly.

Design and development
The Discovery series was designed as a Super Floater glider, for fun, local flying and an emphasis on lightness of weight, ease of rigging and simple handling requirements. It is made from aluminum tubing, with the single-surface wing covered in Dacron sailcloth. All models were British Hang Gliding and Paragliding Association certified.

The series have been frequently used in conjunction with a powered harness, as powered hang gliders.

By the mid-2000s the series had become the best-selling hang gliders in the UK.

Dienone. A dienone is a class of organic compounds with the general formula , where R is any substituent, but often H.  They are formally "derived from 1,4-diene compounds by conversion of a –CH2– group into –C(=O)– group", resulting in "a conjugated structure".  They are a kind of enone.  The class includes some heterocyclic compounds.

Properties and occurrence
The parent member is divinyl ketone.  It is a colorless liquid ([[boiling point|b.p. 38-40 °C) that tends to polymerize upon standing.

Dienones can arise via tautomerism of resorcinols and some hydroxypyridines.  

Being multifunctional, dienones engage in many reactions.  They are often good dienophiles.  They function as ligands, forming metal-alkene complexes such as tris(dibenzylideneacetone)dipalladium(0).

Cyclic dienones
Extensive work has been reported on cyclic dienones. The parent of the seven-membered ring series is tropone.  It is a not only a dienone but a trieneone.

Cyclohexadienones are a significant class of dienones, the premier members being the ortho- and para-quinones.  Many cyclohexadienones convert to phenols. In the dienone–phenol rearrangement, they convert to phenols through the dienone–phenol rearrangement:

The parent cyclopentadienone has only a fleeting existence under laboratory conditions, otherwise it dimerizes.  The substituted derivative tetraphenylcyclopentadienone is however robust solid.

Jones–Dole equation. The Jones–Dole equation, or Jones–Dole expression, is an empirical expression that describes the relationship between the viscosity of a solution and the concentration of solute within the solution (at a fixed temperature and pressure). The Jones–Dole equation is written as

where
 η is the viscosity of the solution (at a fixed temperature and pressure),
 η0 is the viscosity of the solvent at the same temperature and pressure,
 A is a coefficient that describes the impact of charge–charge interactions on the viscosity of a solution (it is usually positive) and can be calculated from Debye–Hückel theory,
 B is a coefficient that characterises the solute–solvent interactions at a defined temperature and pressure,
 C is the solute concentration.

The Jones–Dole B coefficient is often used to classify ions as either structure-makers (kosmotropes) or structure-breakers (chaotropes) according to their supposed strengthening or weakening of the hydrogen-bond network of water. The Jones–Dole expression works well up to about 1 M, but at higher concentrations breaks down, as the viscosity of all solutions increase rapidly at high concentrations.

The large increase in viscosity as a function of solute concentration seen in all solutions above about 1 M is the effect of a jamming transition at a high concentration. As a result, the viscosity increases exponentially as a function of concentration and then diverges at a critical concentration. This has been referred to as the "Mayonnaise effect", as the viscosity of mayonnaise (essentially a solution of oil in water) is extremely high because of the jamming of micrometer-scale droplets.
