Lystek. Lystek International is a Canadian waste treatment technology company founded in 2000 at the University of Waterloo, Ontario, Canada to commercialize treatment technologies for biosolids and other non-hazardous, organic waste materials. Lystek is headquartered in Cambridge, Ontario, Canada and is owned by its management and R.W. Tomlinson Ltd.

Technology
Lystek's technology uses thermal hydrolysis involving high speed shearing, alkali addition and low temperature steam to produce biofertilizer. The product can be sold as a commercial biofertilizer called LysteGro or recycled to anaerobic digesters and biological nutrient removal (BNR) systems for optimization of the wastewater treatment plant operation. The Lystek process condition disintegrates microbial cell wall/membranes and hydrolyzes complex macromolecules into simpler compounds. Recycling up to 25% of the product to the digester increases biogas yields by greater than 30 % and enhances biodegradation, reducing output of biosolids by at least 20%.

Applications
The Lystek system can be installed as a back end, post Anaerobic digestion, post dewatering solution at the wastewater treatment plant. It can also take raw sludge directly without an anaerobic digester process. Alternatively, the system can be used in a regional processing hub to service multiple organic waste generators. The Lystek solution is modular and has a small footprint, making it flexible to deploy and easy to retrofit into existing facilities.

Commercial plants and projects
As of 2015, there are five installations of the Lystek technology in Ontario, and a sixth facility in North Battleford, Saskatchewan. A seventh installation, (first in the U.S.) was planned to be commissioned and fully operational in Fairfield, California by the end of the first calendar quarter of 2016.

Photosynthate partitioning. Photosynthate partitioning is the deferential distribution of photosynthates to plant tissues. A photosynthate is the resulting product of photosynthesis, these products are generally sugars.  These sugars that are created from photosynthesis are broken down to create energy for use by the plant.  Sugar and other compounds move via the phloem to tissues that have an energy demand.  These areas of demand are called sinks.  While areas with an excess of sugars and a low energy demand are called sources.  Many times sinks are the actively growing tissues of the plant while the sources are where sugars are produced by photosynthesis—the leaves of plants.  Sugars are actively loaded into the phloem and moved by a positive pressure flow created by solute concentrations and turgor pressure between xylem and phloem vessel elements (specialized plant cells).  This movement of sugars is referred to as translocation.  When sugars arrive at the sink they are unloaded for storage or broken down/metabolized.

The partitioning of these sugars depends on multiple factors such as the vascular connections that exist, the location of the sink to source, the developmental stage, and the strength of that sink. Vascular connections exist between sources and sinks and those that are the most direct have been shown to receive more photosynthates than those that must travel through extensive connections. This also goes for proximity: those closer to the source are easier to translocate sugars to.  Developmental stage plays a large role in partitioning, organs that are young such as meristems and new leaves have a higher demand, as well as those that are entering reproductive maturity—creating fruits, flowers, and seeds.  Many of these developing organs have a higher sink strength.  Those with higher sink strengths receive more photosynthates than lower strength sinks.  Sinks compete to receive these compounds and combination of factors playing in determining how much and how fast sinks receives photosynthates to grow and complete physiological activities.

Joel Gougeon. Joel Gougeon (born January 13, 1943) was a Republican member of the Michigan Senate from 1993-2002 representing the 34th district (then Ogemaw, Arenac, Bay, Tuscola, and Huron counties). He previously served as a member of the Bay County Board of Commissioners.

Gougeon received a mechanical engineering degree in 1966 from what was then the General Motors Institute by co-oping at the Saginaw Malleable Iron Foundry. After five years in the Air Force, Gougeon and his brothers formed Gougeon Brothers, Inc., which manufactured sailboats, epoxy adhesives, and wind energy blades. The methods first developed by the Gougeon brothers using West System epoxy have become the standard techniques taught in colleges the world over for building boats using epoxy. He was also a member of a number of civic organizations, including as a past president of the Bay City Lions Club and as a founder of the Bay County Crime Stoppers.

First elected in a special election in 1993 to succeed Jim Barcia after he was elected to the U.S. House, Gougeon later won two full terms in the Michigan Senate. He served on the appropriations committee. After his retirement from the Legislature, Gougeon served as a lobbyist for Saginaw Valley State University. Gougeon is also a member of the American Legion, the Elks, and the Vietnam Veterans of America.

Mission Control (video game). Mission Control is an educational platform game developed and published by Sherston Software for use in primary schools.

Plot
As with its predecessor, the game takes place on the planet Oglo. The last remaining rainforest is threatened by dangerous chemicals produced by the antagonist scientist "Gomez", aided by his robots. Through a variety of settings and activities, the player-character must save the planet and the local tribes from the planet's deforestation.

Gameplay

The game is presented in a first-person perspective, in which the player has to use various controls and mechanisms to explore the dense rainforests and solve puzzles. The game contains nine fully narrated interactive activities which include machinery, puzzles, computer programmes and control mechanisms. The player-character takes part in various scenarios including "Lifting the Heavy Box" in which the player has to use the lifting machine to load boxes into the back of a 'hoverheli', the "South Temple Maze" which involves a machine named Rover, who needs to be programmed so that it can find its way through the South Temple Maze. A control panel enables the player to give commands to Rover. "The Chemical Store" ensures the player that the poison trucks are moved safely to the recycling tank without polluting the river. "Switch the Robots Off"  involves a set of coloured lights which has to be programmed in order to deactivate the robots. The final task "Building the Bridge" involves controlling Gomez's machine to build a bridge safely to the island. The player must use logic in order to work out how to build the bridge by dropping stones one-by-one onto the supports.

Statmho. The statmho is the unit of electrical conductance in the electrostatic system of units (ESU), an extension of the centimeter-gram-second (CGS) system to cover electrical units. It is sometimes called the statsiemens, with symbol statS.

Conversion 
In the ESU system, the permittivity of free space is set to unity by definition.  This results in unit conversions to the SI system containing a power of the speed of light, c, as well as a power of 10.  In the case of the statmho, the conversion from siemens (S) is given by:

1 S ≘ c2 × 10−5 s2/m2 × 1 statmho.

The value of c in the SI system is  metres per second exactly by definition. However, in the era in which the ESU system was in use, the speed of light was determined by measurement and was taken to be approximately  centimetres per second.

1 statmho ≘ 1.112650 pS.

The sign ≘ denotes 'correspondence' between quantities.  Equality does not apply, since the systems of quantities underlying the two systems of units are mutually incompatible.

Statohm. The statohm (symbol: statΩ) is the unit of electrical resistance in the electrostatic system of units which was part of the CGS system of units based upon the centimetre, gram and second.

The static units in that system are related to the corresponding electromagnetic units by a factor of the speed of light.  Those units are known as absolute units, and so the counterpart of the statohm is the abohm (abΩ), and their proportions are:

1 statΩ  ≘ c2 abΩ ≈  abΩ where c is the speed of light in centimetres per second.

These units are not common now.  The SI unit of resistance is the ohm (Ω).  The statohm is nearly a trillion times larger than the ohm and is the largest unit of resistance ever used in any measurement system.  The statohm as a practical unit is as unusably large as the abohm is unusably small.

1 statΩ  ≘ c2 ×  Ω ≈  Ω

Emily C. Duncan. Emily Cornelius Duncan (; born 1849) was an American inventor who received two patents in 1903 and 1904 for banking-related calculators.

Duncan was born in Coral, Illinois as Emily Cornelius Forbes and later resided in Centralia, Wisconsin (which later became Wisconsin Rapids) and Jennings, Louisiana. She invented new banking calculators and was mentioned in Inventive Age magazine in February 1905. Duncan was recognized as one of many women who worked in the age of technology before the actual computer. She was married to inventor James Eugene Duncan and although he was believed to be the only inventor in the family written accounts from her granddaughter indicated she assisted her husband with numerous inventions.

Based on her written statement provided in the original patent application she stated that her goal was to provide a "simple and readily understood structure with which computations ordinarily requiring considerable time and care may be accurately and quickly made". The other objective of her invention was "to provide a device of the above character in which parts may be readily substituted, so that computations of different kinds may be made".

The first apparatus was intended for computing interest in 1 at six, seven, or eight per cent. The calculator was first designed to easily be used by any mathematician, but her original patent provided detailed illustration of two apparatuses with details explaining how the calculator was to be operated. The invention was designed more specifically for computing in hundreds.

In 1904, she received another patent for an invention relating to improvements in calculators. Her objective of this invention was to improve the construction of time-calculators and to provide a more durable device designed primarily for determining the number of days between any two dates within a year with absolute accuracy.

Lebouder Autoplane. The Lebouder Autoplane was a French amateur built modular roadable aircraft, with a car-like component that could be separated from its aeronautical parts.  The sole Autoplane flew and drove successfully in the early 1970s.

Design and development

From a distance or in flight, the two seat Autoplane appeared to be a conventional, single engined, high wing braced monoplane with a fixed tail wheel undercarriage. On the ground the front part of the fuselage was seen to be a seriously modified Vespa 400 micro-car, a common, small, four wheeled, open top two seater powered by an  motorcycle engine.  For road use this had lights and direction indicators mounted on a nose grille, a forward bumper and, inside, a standard steering wheel but also a set of flight instruments and engine controls. The Autoplane's roadable component also had both the aircraft's  Continental air-cooled flat four under the bonnet and the original engine which powered it on the road at up to .

The Autoplane had a rectangular plan wing.  Its rear fuselage, open at the front until the car/forward fuselage was inserted, was attached to the wing underside from about half chord and tapered rearwards to a conventional tail with a triangular dorsal fillet leading to a large rectangular fin and rudder. The horizontal tail, also rectangular in plan, was attached to the fuselage bottom.

Joining these two parts into an aircraft took two people a little over half an hour.  The steering wheel stowed in the car and the bumper in the rear fuselage, then the car was backed into the fuselage opening and linked to the wings by attaching on each side a single lift strut to a bracket on the lower car body.  This positioned the windscreen at the wing leading edge and the side windows enclosed the cabin. Entry was via standard car-type, forward hinged doors. Removing the grille revealed  a propeller boss and the propeller was bolted on. The Vespa 400 had been modified so that the front wheels could be swung downward and forward on V struts, forming the Autoplanes's narrow track main undercarriage. Its rear suspension was also modified to allow the wheels to be retracted upwards into the body. After a flight, this procedure was reversed, releasing the car to the road.

The date of the first flight is uncertain but it was before 13 July 1973 when the Autoplane received its Certificate of Airworthiness. Later in 1973 it appeared at two RSA meetings, at Montdidier and Montargis, winning four prizes.  Lebouder flew it until it was damaged in an accident in 1975. The damage was chiefly confined to the undercarriage and propeller but the Autoplane never flew again, though the road vehicle survived.
