Akaflieg Darmstadt D-41. The Akaflieg Darmstadt D-41 was a two-seat, side-by-side configuration sailplane designed to perform as well as tandem seaters.  It was built in Germany in the 1990s and was used by Akaflieg Darmstadt students until it was lost in a crash.

Design and development
The Akademische Fliegergruppe of the Technical University of Darmstadt (Akaflieg Darmstadt) was first formed in 1921. It was, and is, a group of aeronautical students who design and construct aircraft as part of their studies and with the help and encouragement of their University.  The D-41 was completed in 1993.  It was designed to show that a two-seat sailplane of side-by-side layout, with its better visibility for the instructor, who sits in the rear seat in a tandem configuration trainer, and easier instructor-pupil communication, could have as high performance as one with the more usual tandem seat arrangement.

The D-41 was constructed from mixed composite materials, using GRP, CRP and aramid reinforced polymer.  It had a mid-set wing of straight double tapered plan with a continuous straight leading edge with almost no sweep.  Flaps filled the whole of the trailing edge inboard of the ailerons.  The forward fuselage and cockpit region was wider than that of a tandem seater but inclined seats kept the depth down, leading to a flattened oval cross section of not much greater area.  The cockpit was covered with a long, single piece canopy reaching back to the wing leading edge.  Behind the wing the fuselage became slender, ending in a T-tail with straight edged, tapered surfaces.  The D-41 had a retractable central undercarriage. The side-by-side configuration requires cockpit ballast for solo flying and the D-41 also had provision for 200 kg (440 lb) of water ballast for competition flying.

Operational history

The D-41 was used by the Akaflieg students and proved popular, but was lost in a fatal accident during an aborted launch. A spin developed which it was impossible to recover from before crashing, killing both pilots.

Flory–Rehner equation. In polymer science Flory–Rehner equation is an equation that describes the mixing of polymer and liquid molecules as predicted by the equilibrium swelling theory of Flory and Rehner. 
It describes the equilibrium swelling of a lightly crosslinked polymer in terms of crosslink density and the quality of the solvent. 

The Flory–Rehner equation is written as:

where,  is the volume fraction of polymer in the swollen mass,  the molar volume of the solvent,  is the number of network chain segments bounded on both ends by crosslinks, and  is the Flory solvent-polymer interaction term.

In its full form, the Flory–Rehner equation is written as:

where,  is the specific volume of the polymer,  is the primary molecular mass, and  is the average molecular mass between crosslinks or the network parameter.

Flory–Rehner theory 

The Flory–Rehner theory gives the change of free energy upon swelling of the polymer gel similar to the Flory–Huggins solution theory:
.

The theory considers forces arising from three sources:
 The entropy change  caused by mixing of polymer and solvent
 The heat of mixing of polymer and solvent , which may be positive, negative, or zero so, that 
 The entropy change caused by reduction in numbers of possible chain conformations via swelling 

The Flory–Rehner equation was used to model the cooking of steaks in a journal article in 2020

Antonov T-2M Maverick. The Antonov T-2M Maverick is a Ukrainian ultralight trike, designed and produced by Antonov.

Design and development
The T-2M was developed by the Antonov Design Bureau at the end of the Cold War when it became necessary to explore civil markets for aircraft, including microlights for club flying. Aside from production for recreational purposes, the T-2M was also designed for use by the Russian Special Forces for use on infiltration missions, and as such incorporated a sophisticated wing folding mechanism at their request.

The T-2M features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-side-by-side configuration open cockpit, tricycle landing gear and a single engine in pusher configuration. The aircraft is made from tubing, with its wing covered in Dacron sailcloth. Its  area wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The standard engine supplied was the  Rotax 582 twin-cylinder, two-stroke, liquid-cooled powerplant. The smaller  Rotax 503 and the four-stroke  Rotax 912 were also supplied.

The T-2M introduced two features not found on western trikes. It has side-by-side seating, which offers advantages in flight training and also has a large single piece leaf spring main landing gear, which is simple, light, low drag and eliminates many of the large number of parts that other designs use. The aircraft can be operated on wheels, skis and floats. An agricultural aircraft aerial application package is also available.

The T-2M was sold in North America and a dealer, UK-Air, was based in Mississauga, Ontario, Canada. It sold for US$18,500 in 2000.

Kyoto Express. Kyoto Express is a container ship of the Colombo Express class of ships owned and operated by Hapag-Lloyd AG. Registered in Monrovia, Liberia, the vessel has been in operation since 2005.

Hull and engine
Built by Hyundai Heavy Industries in Ulsan, South Korea, the Kyoto Express was completed in November 2005. The ship is fully cellular, has nine holds, and has a cargo capacity of 8749 TEU. The ship is 335.07 meters in length, 42.87 meters across the beam, and draws a draught of 14.61 meters.

The ship features a main propulsion plant of a B&W 12K98ME that generates 93,323 hp. The main engine drives a single, fixed-pitch screw, capable of propelling the vessel at a speed of 24.5 knots.

Crane collapses at docks
On January 18, 2008 at approximately 4:35pm, a crane collapsed onto the Kyoto Express at the Southampton Container Terminals. The part of the dock was evacuated, and there were no reported injuries.

Even after four weeks from the crane incident, many ships and vessels had to reroute to other ports due to the dock's suspended operations for rebuilding and repairing. The Kyoto Expresss departure was delayed for about 10 days while debris and damaged containers from the collapse were cleared from the ship and dock.

Due to the incident, Honda lost total production at its South Marston factory because the parts could not be delivered, and the 5,000 staff members were sent home. The Kyoto Express was carrying gearboxes and transmissions for Swindon from the Far East that were eventually rerouted to Amsterdam which had to be then transported on land to the United Kingdom.

"This crane failure at Southampton at the weekend has caused us a major problem with the unloading of key engine components," said Julie Cameron, head of corporate communications at Honda. "As a result the car production was disrupted due to this parts shortage. Arrangements have been made to transport the outstanding parts, by road, back to the UK. We are expecting delivery this morning, when full production is estimated to restart on both lines. During this non-production time, associates are being given an opportunity to take holidays and other activities such as training are planned."

The projected loss of production was between 600 and 1,000 vehicles.
