Lincoln Construction Co.. The Lincoln Construction Company was an American construction company in Nebraska.  The company built several bridges in Nebraska between 1913 and 1916.  A state engineer, after inspecting one of the company's bridge, found that "the workmanship as a whole was decidedly poor" and recommended suspending all payments on the bridge until the "poor appearance" was remedied.  Company president, W.S. Collett, stated that the company's experience in the bridge business had been "more or less disastrous, from a financial point... which leads me to the conclusion that I had better quit while my credit remains good."

Despite the findings of the state engineer, five of the bridges built by Lincoln Construction Company have been listed on the National Register of Historic Places. They are: 
Cambridge State Aid Bridge, on Nebraska Highway 47 over the Republican River, 0.6 miles south of Cambridge, Nebraska (Lincoln Construction Co.), NRHP-listed
Carns State Aid Bridge (1913), County Road over the Niobrara River, 10.8 miles northeast of Bassett, Nebraska (Nebraska State Engineer, designer, Lincoln Construction Company, builder), NRHP-listed
Deering Bridge (1916), County Road over School Creek, 2 miles north, 2 miles east of Sutton, Nebraska (Nebraska Bureau of Roads & Bridges, designer, and Lincoln Construction Company, builder), NRHP-listed
Stewart Bridge, County Road over Big Sandy Creek, 1 mile east and 8 miles north of Oak, Nebraska (Nebraska Highway Department and Lincoln Construction Co.), NRHP-listed
Sutherland State Aid Bridge (1914–1915), County Road over the North Platte River, 4.2 miles north of Sutherland, Nebraska (Nebraska Bureau of Roads & Bridges, designer, and Lincoln Construction Company, builder of the arches), NRHP-listed

Steffturbine. The Steffturbine is a turbine for generating electrical energy using hydropower. Their functioning and performance was proven by the scientific investigations of Ivo Baselt within the framework of his dissertation.

The Steffturbine is suitable for the use in micro or small hydro-electric power stations and can be operated as a modular system. Modules can be deployed with heads of between 3 and 5 meters and maximum flow rates of 0.5 m3/s to generate up to 10 kW of electric power. The Steffturbine has been developed by Walter Reist Holding AG and is marketed as a complete system with generator and control electronics included.

Function 

The Steffturbine is driven by the potential energy of the water, it operates like an overshot water wheel. It comprises a conveyor chain equipped with profiled paddles circulating around two wheels. These wheels are arranged so that the flowing water drives the conveyor chain on an inclined plane.  Different turbine inclinations are possible.

Water is fed to the Steffturbine through an inlet channel. The inflow of water loads the paddles. The power thus exerted onto the paddles causes the chain, which is mounted to run on roller bearings, to move. In turn, the circulating chain imparts a rotational motion to the drive wheels. A generator is connected to the rotating drive wheels via an overdrive transmission. The generator converts the rotational mechanical power into an electrical output. The resultant electrical power is modulated by means of the electronic control system and adapted to the different operating modes.

Applications 

The Steffturbine can be employed for grid supply in isolated or stand-alone operation or as part of a combined network solution. The mechanical design is the same for all operating modes, and only the output electronics require fitting with different components. The Steffturbine can be deployed in any location where water flows down a gradient, for example rivers, dams, treatment plants, or existing weirs set for revitalization, with the inclination and length of the Steffturbine being adjusted to the local conditions. In the simplest case, the Steffturbine can also be laid on the surface, for the water to flow through it. As a result, the river-course ecosystem remains largely unaffected.

Efficiency 
The turbine is at its most efficient at inclinations between 30° and 60°. Its efficiency during the individual development phases was tested under laboratory conditions. For the first prototype, a maximum of 86% was achieved. Implementation of optimization options derived from the tests resulted in an improvement of turbine efficiency to 92%.

Stacking factor. The stacking factor (also lamination factor or space factor) is a measure used in electrical transformer design and some other electrical machines. It is the ratio of the effective cross-sectional area of the transformer core to the physical cross-sectional area of the transformer core. The two are different because of the way cores are constructed.

Transformer cores are usually made up of thin metal sheets stacked in layers. The layers are laminated with varnish or other insulating material. The purpose is to reduce eddy currents in the core while keeping a high magnetic flux.  Since the insulator is non-ferro-magnetic, little, if any, magnetic flux is contained within it.  It is mainly in the metal sheets.  The insulation takes up a finite space, so the effective area the flux occupies is less than the physical area of the core. The stacking factor depends on the thickness of the lamination of the steel sheets which comprise the core.

The stacking factor is usually 0.9. The stacking factor is always less than 1.

The stacking factor is used when calculating the magnetic flux density within the core. Because the flux is confined within a smaller area in a laminated core, the flux density is higher than it would be in a homogeneous core.

Laminated cores always have a stacking factor less than unity; a stacking factor of unity implies no laminate at all. Stacking factors are typically 0.95 or higher for transformer cores and machine stators. However, cores made from amorphous metal have a stacking factor of around 0.8, compared to 0.96 for silicon steel.

A related concept in transformer design is window space factor. This is defined as the ratio of the area occupied by the copper windings to the area of the space they pass through (the "window"). The higher the operational voltage of the transformer, the smaller this ratio needs to be in order to provide more space for insulation.

Martin-Handasyde No. 3. The Martin Handasyde No.3 was an early British  single-seat monoplane design, built in partnership by H.P. Martin and George Handasyde. Only one was built.

Design and development
The  Martin-Handasyde No.3 bore a strong resemblance to the Antoinette monoplanes, with a slender  wood-covered triangular fuselage, and tapered wings which were braced by mid-span kingposts.  Lateral control was by wing-warping and the angle of incidence of the wings varied from 5° at the wing root to zero at the tip.  The undercarriage consisted of a pair of wheels on a cross-axle supplemented by a forward-projecting curved skid.  It was initially powered by a  Antoinette V-8 engine. This was later changed for a  J.A.P.

It was first flown at Brooklands by H.P. Martin during November 1910, and was flown throughout 1912 by Graham Gilmour, who was eventually killed in the aircraft when it suffered a mid-air structural failure over Richmond Park on 17 February 1912.

A two-seater version of the aircraft, the Martin Handasyde 4B, also called the Dragonfly, with a wingspan of  was built for Thomas Sopwith and was displayed at the 1911 Aero Show at Olympia.

Stella Atkins. Stella Atkins is a Professor Emeritus in computing science at Simon Fraser University in Canada, and one of the founding members of the Systers community for technical women in computing. Her primary research interests are in medical computing (includes laparoscopic surgery, sleep studies and telehealth) and medical image display and analysis.

Education 
Atkins grew up in England with an intense interest in math. Her father was an engineer and her mother, a statistician. She enjoyed reading math books for fun but because her sister was studying mathematics in college, she wanted to take a different route and pursued chemistry studies instead. When choosing a university, Atkins chose University of Nottingham in England, because chemist Dorothy Hodgkin, who had just received a Nobel Prize in Chemistry, was there. 

After Atkins received her B.Sc. in chemistry from Nottingham University (1966), she went on to work at the Shell Refining Company as a chemical engineer. There she performed simulations of oil refineries and oil flow, and developed her interest in computing. 

Atkins later became a scientific computer programmer advisor at the University of Warwick in England and received her M.Phil. in computer science from there in 1976. In 1985, Atkins received a Ph.D. in computer science from the University of British Columbia.
