Morgan Jones (railroad builder). Morgan Jones (7 October 1839 – 11 April 1926) was an American railroad builder, born in Wales.

Early life
Morgan Jones was born at Tregynon, near Newtown in Powys, Wales, the son of Morgan Jones and Mary Charles Jones.  He worked on the family farm as a young man, but served an apprenticeship with the Cambrian Railways before he emigrated in 1866.

Career
In America he became foreman of a construction crew on the Union Pacific Railroad, with Grenville M. Dodge as his mentor. He was present for the driving of the "Golden Spike" joining the rails of the First transcontinental railroad in 1869.  In 1876 he was hired by Grenville Dodge, then at the Texas & Pacific Railway, to finish an extension project into Fort Worth. He brought the construction in on time, within a strict deadline from the state legislature, and was hailed as a local hero for the timely completion.

Jones went on to build and operate hundreds of miles of railroad, mostly in Texas, mostly without land subsidies. He was president of the Fort Worth & Denver City Railway, one of his most successful projects. He was also director of the Wichita Valley Railway Company.

Personal life
Jones was a bachelor. Two of his nephews from Wales, Morgan C. Jones and Percy Jones, joined him in the Texas railroad business. He lived in Abilene, Texas, at the Hotel Grace in his later years, and died in 1926, age 86.

In 2014 there was a segment on BBC Radio Cymru about Morgan Jones the Texas railroad man. His great-nephew Grant Jones was a longtime Texas state legislator.

Mühlhäuser. Mühlhäuser was a manufacturer of railbound and trackless tunnel construction equipment, such as narrow gauge rolling stock, rails, and switches; conveyor belts, concrete, and grouting and formwork equipment; and off-road service vehicles on rubber wheels.
Due to mismanagement, the company was declared bankrupt in 2019, And It was acquired by Mining Equipment Ltd. in 2020.

History 
Mühlhäuser was founded in 1907 by three Mühlhäuser brothers. In 2013, fourth-generation family member Hubertus Mühlhäuser took over the majority of the shares from his father, uncle and cousin, and later retired as managing director, in 2015. The company was later sold to Mining Equipment Ltd., in 2020.

Mühlhäuser provided equipment for the construction of the Elbe Tunnel, the New York City Subway, the Channel Tunnel and the Gotthard Base Tunnel. After the completion of the Channel Tunnel, Mühlhäuser bought back some of the used equipment and rented it out or sold it refurbished for other tunnel construction projects. For the Gotthard Base Tunnel they built bespoke ambulance trains, fire service trains and a big vacuum cleaner to remove any dust particles from the tunnel.

Apache Tika. Apache Tika is a content detection and analysis framework, written in Java, stewarded at the Apache Software Foundation. It detects and extracts metadata and text from over a thousand different file types, and as well as providing a 
Java library, has server and command-line editions suitable for use from other programming languages.

History 
The project originated as part of the Apache Nutch codebase, to provide content identification and extraction when crawling. In 2007, it was separated out, to make it more extensible and usable by content management systems, other Web crawlers, and information retrieval systems. The standalone Tika was founded by Jérôme Charron, Chris Mattmann and Jukka Zitting. In 2011 Chris Mattmann and Jukka Zitting released the Manning book "Tika in Action", and the project released version 1.0.

Features 
Tika provides capabilities for identification of more than 1400 file types from the Internet Assigned Numbers Authority taxonomy of MIME types. For most of the more common and popular formats, Tika then provides content extraction, metadata extraction and language identification capabilities.

It can also get text from images by using the OCR software Tesseract.

While Tika is written in Java, it is widely used from other languages. The RESTful server and CLI Tool permit non-Java programs to access the Tika functionality.

Notable uses 
Tika is used by financial institutions including the Fair Isaac Corporation (FICO), Goldman Sachs, NASA and academic researchers and by major content management systems including Drupal, and Alfresco (software) to analyze large amounts of content, and to make it available in common formats using information retrieval techniques.

On April 4, 2016 Forbes published an article identifying Tika as one of the key technologies used by more than 400 journalists to analyze 11.5 million leaked documents that expose an international scandal involving world leaders storing money in offshore shell corporations. The leaked documents and the project to analyze them is referred to as the Panama Papers.

Gino Colombini. Gino Colombini (1915–2011) was an Italian architect and industrial designer.

From 1933 to 1952, Colombini worked in the Milan practice of the architect and designer Franco Albini.

From 1953 to 1960, Colombini was the technical director of Kartell, which was founded by Giulio Castelli to produce plastic injection moulded products. Kartell produced modern household appliances that were distinctive and colourful, which represented a complete transition from the typical utilitarian aesthetic of the 1950s.

Colombini designed many household products for Kartell that were revolutionary and affordable examples of everyday items. His products include a carpet beater (1957), a lemon squeezer (1958), plastic wash basins, salad colanders, lunch boxes and a long-handled cleaning scoop (1959). One of his most famous designs is a round umbrella stand made from ABS plastic with a stainless steel ashtray top (1965).

Colombini was awarded the Compasso d'Oro for designs that he produced for Kartell in 1955, 1957, 1958, 1959, and 1960. He died in 2011.

Clifton, Rawcliffe and Poppleton Ings. Clifton, Rawcliffe and Poppleton  ings are temporary storage area (washland scheme) for water that flows down the River Ouse in York, England.

Approximately  of water is able to be stored here which lowers the flood level by about  in the city.

Sluice gates on the north and south side allow water to enter and leave.

During the summer months the grassland is used by local farmers to graze their cattle.

In 1982, £1.25 million, was spent on increasing the height and adding sluice gates as well as heightening the embankments to allow greater storage of water.

The design of the ings allow for accommodation of water for a medium order flooding.

In the event of a higher order flooding, the embankments allow overflow thus increasing capacity of the ings.

Embankments (floodwalls) 

This area makes use of a lot of embankments.

An embankment  high typically has a footprint  wide which makes it unsuitable in some areas.

Within the embankment there is a central core, either clay or man made structure like concrete or metal piling. This gives added integrity and prevents water from seeping through under or over the embankment.

Flood scheme 
This is one of many flood defences that make up a scheme. Other projects include River Foss Barrier, Leaky dams, ings, washland storage basin, walls, and embankments.

After the flooding on 26 December 2015, the UK government proposed a complete rethink on national flood defences.

One project that showed promise with the added benefit of a fraction of the cost of concrete barrier is the Pickering flood defences that composed a plan to store as much water upstream to allow soaking into the surrounding areas and prevent flooding downstream.

Saab 107. The Saab 107 was a proposed series of small airliners that were intended to be manufactured by Saab AB of Sweden, but were never built.

Development
Two variants of a feederliner project were under development at Svenska Aeroplan AB from 1966 to 1968 with a projected first date of operation in 1973, the Saab 1071 and the Saab 1073. The design goals for both designs were minimization of turnaround time at an airport as well as production and operation costs. Following an intensive market research Saab wanted to compete with terrestrial transport in both aspects. A model of the 1071 was presented at the Hannover air show in April 1968 and model photos as well as illustrations of both projects appeared in the specialized press at about the same time. Saab needed foreign partners to share the development costs, and as none were forthcoming, Project 10 was abandoned.

Design

The Saab 1071 was projected for very short distances between small domestic airfields and international hub airports. The design featured a high wing with rectangular plan form, a circular pressurized fuselage for 40 passengers and four turboprop engines in the 800 h.p. class. Development costs were estimated at 100 million SEK and the final unit sales costs at maximal 5 million SEK. Wings and fuselage were designed to be easily stretchable at low development costs if needed later on. The wing was equipped with simple, single-pivoted slot flaps to obtain high lift for short take offs within 800 m runway. Propeller thrust reversal was intended to be used for reduction of the landing distance.

The second project Saab 1073 was intended for passenger and freight transport on somewhat longer domestic lines between airports that offer runways of 1200 m length or more. For this, the STOL requirement was less severe and for a better cruising economy the design featured two turbofans in nacelles under the high wing which had a moderate wing sweep. The T-tail kept the elevator out of the exhaust jets. The intended turbofans were in the 10,000 lb-thrust class (Rolls-Royce Trent) and the passenger capacity amounted to 80. Development costs were estimated at 300 million SEK and the final sales price at maximal 15 million SEK. Realization of this project would have needed public support as well as cooperation with a large foreign aircraft manufacturer.

SEA.1. The SEA.1 was a Belgian, multi-purpose, light twin engine monoplane flown in 1936.  Only one was built; it was later converted into a single engine aircraft and used by the military.

Design
The SEA-1 was the first aircraft built by the Société Belge d'Etudes Aéronautiques to their own design. It was intended to be capable of many rôles, both civil and military, in the same way as the Avro Anson and Potez 26 families. It was an up-to-date aircraft with a simple structure, not needing advanced construction skills or facilities.

In plan its cantilever low wing was strongly straight tapered, with almost all the sweep on the trailing edge. The wingtips were semi-elliptical. It had a one-piece, wooden, two box spar structure with plywood skin.  The outer parts of the wing carried broad chord, fabric covered ailerons with flaps inboard from the ailerons to the fuselage.  Its , five cylinder Armstrong Siddeley Genet Major IA radial engines were mounted close to the fuselage, well ahead of the leading edges.  They were enclosed in broad chord cowlings, with long nacelles behind them that reached to the trailing edges.  Their fuel tanks were in the wing.

The slim, tapered, flat-sided fuselage was built around four chrome-molybdenum steel longerons and was fabric covered. Its enclosed cockpit had side-by-side seats at the leading edge, with a cabin behind them lit by four windows on each side and fitted with up to six passenger seats.  It was entered by a large, port-side door. At the rear, the tapered horizontal tail was mounted close to the top of the fuselage and carried inset, trim tab-assisted elevators.  The SEA-1 had a small fin but a large, rounded, balanced rudder which was also tab-assisted.  The tail surfaces were all ply covered.

The SEA-1 had a retractable undercarriage.  Its low pressure mainwheels were fork-mounted with oleo strut shock absorbers under the engines, resulting in a track of ; the wheels were enclosed in the nacelles in flight.  There was a small tailwheel on the fuselage under the rudder.

Development

The SEA-1 was registered as a Peetermans SEA.1, OO-PET, on 28 May 1936. The date of its first flight is not known but by early September 1936 it had flown for fifteen hours. It appeared at the Brussels Aero show in 1937, which opened on 26 May, but by mid-1938 it had undergone major revisions which replaced the twin Genet Majors with a single , seven cylinder Armstrong Siddeley Cheetah radial and also replaced the retractable undercarriage with fixed gear.

It was removed from the civil register on 7 July 1938 and used as a training machine by the Belgian forces.

Lerotholi Polytechnic. Lerotholi Polytechnic is a technical and vocational school in Maseru, Lesotho.

History and operations
Lerotholi Polytechnic (LP) is an autonomous public institution that was established in 1905. It is governed by the Lerotholi Polytechnic Act of 1997 and offers both Crafts and Technician programmes.

The institution comprises four schools, namely, the School of Engineering and Technology (SET), and the School of the Built Environment (SOBE), which offers certificates in craft programs and diplomas in engineering. The School of Enterprise and Management (SEM) offers certificates in Textiles and diplomas in commercial programmes. The School of Continuing Education (SOCE) focuses on increasing access to education by offering specific need-based programs and courses to industry and the general public while also using available opportunities to generate income for the institution. 

Chief Lerotholi first conceptualized Lerotholi Polytechnic, as a technical and vocational school in 1894, to be the first of its kind in Lesotho. In 1905, the first building was erected and various courses in trades were introduced. New skills and trades were added to the curriculum in 1929.

In 1960, the school changed to an artisan-oriented institution. Two new schools were established in the 1970s and 1980s, the Commercial Training Institute and the Technician Training School. In 1991, the three schools were merged. This amalgamation came to be known as Lerotholi Polytechnic (LP).

In an effort to respond to the global trends of liberalization, the government of Lesotho relinquished its responsibility over the institution and granted it autonomy through the LP Act, No. 20 of 1997 – a move intended to afford the institution the leverage to decide its own strategic direction.

Controversy 
Since 2009, Lerotholi Polytechnic has received significant negative attention for the abusive hazing rituals allegedly targeted at first year students. The school was forced to cancel its graduation ceremony during the same year after a student was beaten to death by former students. At least six students have reportedly died as a direct result of the school's “initiation” traditions.

Rutan Grizzly. The Rutan Model 72 Grizzly is a tandem-wing STOL research aircraft designed by Burt Rutan, now preserved at the EAA AirVenture Museum, Oshkosh. The aircraft exhibited excellent short take-off and landing (STOL) capabilities.

Design and development

This composite-construction aircraft features three lifting surfaces: A front wing with approximately half the span of the main wing and a cruciform empennage. Front and main wings are connected by a pair of struts with square cross-section which also serve as fuel tanks. Both wings carry Fowler flaps on part of their span for STOL. The fixed tail-wheel undercarriage has four low-pressure, small-diameter main-wheels, on two cantilever spring struts, with a spring mounted tail-wheel assembly. The four-seat cabin is completely enclosed with a combination of flat, squared and outward-bulged tear-drop shaped windows.

After completion of testing the Grizzly was donated to the EAA AirVenture Museum, Oshkosh in 1997.
