SCAL FB.40. The SCAL FB.40 was a French, side-by-side seat biplane trainer chosen in 1938 for widespread use in the Aviation Populaire programme. The Second World War prevented large scale production but at least two were restored post-war, one becoming a familiar rally participant.

Design and development

After completing the nationalization of the French military aviation industry in April 1937, government attention turned to the civil sector with the establishment of the Aviation Populaire programme aimed at popularizing flying. This was proposed by the Ministre de l’Air (Air Minister) in June 1936 and officially established in July. By the end of 1937 a selection of seventeen suitable aircraft in different stages of development, including the FB.40, had been made. 

The FB.40 was a wooden, equal span biplane, with rectangular plan wings mounted with marked stagger. The lower wings were mounted on the lower fuselage longerons and the upper wing was held centrally over the fuselage on cabane struts, with N-form interplane struts completing the structure. Full span ailerons were fitted only to the lower wings.

The FB.40 was powered by a , air-cooled, four cylinder inline Régnier 4D.0. Student and instructor sat side-by-side under a cut-out in the trailing edge of the upper wing which improved their upward field of view. The tail was angular with a cropped triangular fin carrying a near rectangular rudder. Its tailplane was mounted on top of the fuselage and braced to it from below. The elevators were also rectangular in plan apart from a cut-out for rudder movement.

The FB.40 had a fixed, conventional undercarriage with its wheels on longitudinal, outward-leaning, faired V-struts hinged on the fuselage centreline. Long, thin shock absorbers were mounted on the upper fuselage longerons.

Operational history

The exact date of the first flight of the FB.40 is not known but by 30 October 1938 its initial tests at Orly, where it was flown by Henry Thibault, had proved it ready to go to C.E.M.A. at Villacoublay for certification. By 20 May 1939 the   Minié 4 D0 Horus flat four-powered FB.41 variant had logged 10 hours flight, demonstrating good flight characteristics as well as a top speed of . Though both types were offered for sale there was to be little time to build many production aircraft before the outbreak of World War II in September. No details from this period are known; however, at least two airframes survived the war.

An FB.40 was offered for sale in 1948 which may have been the aircraft that in 1949, fitted instead with a  Continental A65-8 flat four engine, began competing in rallies. Designated a FB.41, it was owned by the Aero Club de Versailles between 1957 and 1962 and based at Saint-Cyr-l'École but by 1964 was no longer on the French civil register.

By about 1954 the second survivor had been modified, though apart from a photo little is known about it.

TU Delft Library. The TU Delft Library is the main library of the Delft University of Technology (TU Delft), located in Delft, Netherlands. It was designed by the Dutch architecture firm Mecanoo and built in 1997. It is the largest technical scientific library in the Netherlands.

Building 
The library was designed in the early years of Mecanoo, whose founding members, Erick van Egeraat, Henk Döll, Francine Houben, Roelf Steenhuis and Chris de Weijer, were graduates of TU Delft. An example of a building that acts as landscape, the library is partially underground with a 15% sloped plane and a grass-covered green roof on top. Protruding from the artificial hill there is a  steel cone which acts as a source of daylight and is meant to symbolize technical engineering. Although a successful exterior element, the cone was more unsatisfactory in the interior and received some criticism in architectural reviews. A series of columns distribute heat and light throughout the interior.  The green roof system by ZinCo Benelux uses a cellular glass insulation and a  substrate. Together with the green roof and the insulation it provides, a reduced external wall surface improves the building's energy efficiency. The roof is walkable and the students use it to sit and socialize during the summer, or as a sledding hill during the winter.

In the central hall the lending desk occupies the space at the bottom of the cone, surrounded by steel struts, with the east wall covered by suspended steel-frame bookcases going up four floor and accessible via stairs. The edge of the building is used for staff offices, with a fully glazed exterior window wall. The library is located in the center of the campus next to the brutalist-style auditorium Aula, by Jo van den Broek and Jaap Bakema, providing a new spatial context to that building. The building received awards such as the Award for the Millennium, Corus Construction (2000), and has been selected as one of the most original and beautiful libraries in the world by Condé Nast Traveler and CNN Travel respectively.

Collections and activities 
The library is the university's central library and also includes a learning center, student workspace rooms, a bookshop and a café. As of 2017 it had a collection of more than 862,000 books, and 16,000 magazine subscriptions. The TU Delft Library is a founding partner of DataCite, a global network established to "improve access to research data on the Internet". In 2017 the library started a data stewardship project focused on research data management.

Elly Schwab-Agallidis. Elly Schwab-Agallidis (born Elly Agallidis, , ;  – ) was a Greek physicist/physical chemist and one of the first women in Greece to be awarded a PhD in the field. She was the wife of Georg-Maria Schwab, who met her in Munich as the supervisor of the experimental work for her doctoral thesis; the couple then worked together as researchers in the Kanellopoulos Institute after they emigrated in Greece. Her most famous work concerned the properties and reactivity of parahydrogen.

Biography 
Elly Agallidis was born in 1914 to a middle class family of Athens; she was the first child of Ioannis Agallidis and Maria-Edith Agallidis (née Zannou). She graduated with a degree in Physics from the University of Athens in 1934 and continued with postgraduate studies in the Physical Chemistry Laboratory of the University of Munich, then under the direction of Heinrich Otto Wieland. It was there that she met Georg-Maria Schwab, her future husband, who suggested that she examine parahydrogen and supervised her experimental work.

Schwab was banned from teaching in Nazi Germany due to his half-Jewish origin. With the increasing fear of prosecution, he decided in 1930 to emigrate to Elly's homeland, Greece. Agallidis and Schwab married in Athens the same year. Schwab-Agallidis was able to find work for both in the chemical laboratory of the Kanellopoulos Institute of Chemistry and Agriculture, where the couple collaborated on various topics of physico-chemical research for the next ten years (1939–1949). Among those topics Schwab-Agallidis continued her work on the properties of parahydrogen, for which she received her PhD by the Department of Physics of the University of Athens in 1939 and published multiple relevant papers in the following years. At the same period she also delivered lectures on Physical Chemistry at the University of Athens.

After a difficult period for the couple during the Axis occupation of Greece and the resumption of their research after the liberation of Greece, the two scientists eventually returned to West Germany when Schwab was offered the Professorship of Physical Chemistry at the University of Munich in 1951.

Elly Schwab-Agallidis died in Essen at the age of 92 in 2006.

Green transport hierarchy. The green transport hierarchy (Canada), street user hierarchy (US), sustainable transport hierarchy (Wales), urban transport hierarchy or road user hierarchy (Australia, UK) is a hierarchy of modes of passenger transport prioritising green transport. It is a concept used in transport reform groups worldwide and in policy design. In 2020, the UK government consulted about adding to the Highway Code a road user hierarchy prioritising pedestrians. It is a key characteristic of Australian transport planning.

History
The Green Transportation Hierarchy: A Guide for Personal & Public Decision-Making by Chris Bradshaw was first published September 1994 and revised June 2004. As part of a pedestrian advocacy group in the United States, he proposed the hierarchy ranking passenger transport based on environmental emissions. The reviewed ranking listed, in order: walking, cycling, public transport, car sharing, and finally private car.

It was first prepared for Ottawalk and the Transportation Working Committee of the Ottawa-Carleton Round-table on the Environment in January 1992, only stating 'Walk, Cycle, Bus, Truck, Car'.

Trip length
Trip speed

Adoption
The author directed the hierarchy at both individual lifestyle choices and public authorities who should officially direct their resources – funds, moral suasion, and formal sanctions – based on the factors.

Bradshaw described the hierarchy to be logical, but the effect of applying it to seem radical.

The model rejects the concept of the balanced transportation system, where users are assumed to be free to choose from amongst many different yet ‘equally valid’ modes. This is because choices incorporating factors that are ranked low (walking, cycling, public transport) are seen as generally having a high impact on other choices.
