Tom Balding Bits & Spurs. Tom Balding Bits & Spurs is a small metalwork manufacturer in Sheridan, Wyoming that designs and sells handmade equine riding equipment. Their products, most notably bits and spurs, are used by professional horsepeople and trainers.

History
In the 1960s, Tom Balding began working with metal as a teenager in Ontario, California, building such things as custom hot rod parts and aluminum backpack frames. In 1974, he opened his first welding and fabrication shop specializing in a precise type of welding called TIG welding.

He continued to TIG weld in the aerospace and sailing industry until he moved to Sheridan, Wyoming in the late 1970s. In Wyoming, he worked as a ranch hand until 1984, when a neighbor asked him to repair a broken bit.  He built her a new one, and for the next 15 years, he ran Tom Balding Bits & Spurs out of a repurposed mobile home.

After that, the business expanded due to increased popularity from the endorsement of multiple National Reined Cow Horse Association (NRCHA) Snaffle Bit Champions such as Bobby Ingersoll. The business is now widely recognized throughout the world of western horsemanship.

Metalwork Products
The company handcrafts metalwork products and  other items in Sheridan, Wyoming. All custom pieces are made at the fabrication shop where they are precision cut into parts and fitted together, instead of being cast. Each part of every product is made to 1/1000 of an inch accuracy.

Their products include spurs, custom spurs, heel bands, shanks, and rowels. They also handcraft bits made for shank bits, snaffle bits, baseline bits, bit shanks, and mouthpieces for Western and English markets.

The company also sells other items such as jewelry and belt buckles, including a variety of silver and turquoise jewelry; money clips, leather belts, and photo albums.

Tom Balding Bits & Spurs products are known for their design and craftsmanship and  have been featured in galleries and in museums. The company has also been featured on Discovery Channel’s How It’s Made.

Command Query Responsibility Segregation. In information technology, Command Query Responsibility Segregation (CQRS) is a system architecture that extends the idea behind command–query separation (CQS) to the level of services. Such a system will have separate interfaces to send queries and to send commands. As in CQS, fulfilling a query request will only retrieve data and will not modify the state of the system (with some exceptions like logging access), while fulfilling a command request will modify the state of the system.

Many systems push the segregation to the data models used by the system. The models used to process queries are usually called read models and the models used to process commands write models.

Although its origin is usually attributed to Greg Young in 2010, everything indicates that the precursor of CQRS was Udi Dahan who in August 2008 published on his blog a training course that aimed to apply CQRS together with SOA  and in more detail in December 2009 in the article Clarified CQRS.

I-Tree. i-Tree is a collection of urban and rural forestry analysis and benefits assessment tools.  It was designed and developed by the United States Forest Service to quantify and value ecosystem services provided by trees including pollution removal, carbon sequestration, avoided carbon emissions, avoided stormwater runoff, and more. i-Tree provides baseline data so that the growth of trees can be followed over time, and is used for planning purposes. Different tools within the i-Tree Suite use different types of inputs and provide different kinds of reports; some tools use a 'bottom up' approach based on tree inventories on the ground, while other tools use a 'top down' approach based on remote sensing data. i-Tree is peer-reviewed and has a process of ongoing collaboration to improve it.

There are seven different i-Tree applications which can enhance an individual's or organization's understanding of the benefits which trees provide in modern society. Over the course of many years the U.S. Forest Service has developed and refined these different applications: i-Tree Eco, i-Tree Landscape, i-Tree Hydro, i-Tree Design, i-Tree Canopy, i-Tree Species, and i-Tree MyTree.

History

i-Tree began in 2002 as survey of a sample of urban forest to simulate taking a tree inventory of an entire urban forest.  It then added hand held devices for efficient inventory of street trees.  The current version of i-Tree includes different tools which allow for several sources of data to be used, such as National Land Cover Data, Google Maps, and tree inventories. Some tools use continuous data on air pollution and meteorology for more accurate results.

Research 

Researchers using i-Tree have examined:

 The benefits of urban trees 
 Selecting the best tree planting locations 
 Storm damage to urban forests
 Potential bird habitats
 PM2.5 removal and health effect

Vieww. Vieww, previously known as GoalControl, is a German company based in Aachen,  which provides technologies for use in sports.

The company's main product is a goal-line technology for association football, called Vieww 4D (also previously known as GoalControl). The system features 14 high speed cameras which are mounted around the stadium, 7 directed to each of the goals. These cameras are used to detect if the ball has crossed the goal line or not. The camera is capable of taking 500 pictures per second and the ball's movement within . The data from the camera  is then sent to the central image processing center located within the stadium using a fiber optics cable, where a virtual representation of the ball is output to confirm the goal. The referee is equipped with a watch displaying the camera's data which will vibrate and display a signal whenever a goal is scored. This signal is then transmitted wirelessly.

The technology was licensed by FIFA in early 2013 alongside competing systems GoalRef, Hawk-Eye, and Cairos. Testing of the camera systems were completed in February, 2013. The GoalControl system was used at the 2013 Confederations Cup as a trial run, where it detected 68 goals and during the 2013 FIFA Club World Cup to track the ball, while GoalRef was used for display. The system was used 2014 World Cup in Brazil where it would be the first World Cup to feature goal-line technology. During the 2014 World Cup, one notable event of the GoalControl goal-line technology being used to award a goal was in the group E match between France and Honduras in which a kick from France's Karim Benzema bounced back from the goal post and an attempt to save the ball by Honduras' goalkeeper Noel Valladares led to an own goal.

A vote cast in early 2014 by the 36 German clubs of the first and second division decided with only 12 out of 36 votes for using the system due to the "exorbitant cost" of €250,000 (chip in the ball) to €500,000 (Hawk-Eye, GoalControl) per club. The support of 24 clubs would have been required to carry the motion.

Industrial Extraction. Industrial Extraction is the process by which harmful air contaminants are removed from the work place for the protection of employees and the environment.

In the UK, the Health and Safety Executive has implemented COSHH regulations to ensure all industrial workplaces protect the health of their employees via effective Local Exhaust Ventilation (LEV).  This policy is now being mirrored in other parts of the world including China and North America.

Harmful air contaminants can be particles, gases or vapours and/or combinations or all three. ‘Particles’ include dusts, fumes, mists and fibres.

Extraction systems 
Extraction systems to remove airborne particles from industrial workplaces have been in use for a number of years.

Centrifugal systems 
Centrifugal systems are used in a wide range of manufacturing applications in industries including aerospace, automotive, medical, defence and food production. These systems use a perforated drum with specially designed vanes which rotate at very high speeds. Oil mist is drawn into the unit and impacts on the vanes at high velocity and specially designed synthetic pads assist the collection process and filter out stray solid particles.

The centrifugal force then pushes the oil to the unit’s outer case where it drains back to the machine for re-use or collection and clean air is returned to the workshop through the top of the unit. The dangerous particles have been removed and employees are protected from the potential health hazards associated with breathing in polluted air.

2,4-Diaminotoluene. 2,4-Diaminotoluene is an aromatic organic compound with the formula . It is one isomer of six with this formula. It is a white solid, although commercial samples are often yellow-tan.

Preparation
It is prepared by hydrogenation of 2,4-dinitrotoluene using a nickel catalyst.  Commercial samples often contain up to 20% of the 2,6-isomer.

A laboratory method involves reduction of 2,4-dinitrotoluene with iron powder.

Use
It is mainly used to manufacture toluene diisocyanate, which is a key raw material in polyurethane chemistry. It is still the starting material used when non-phosgene methods of production of toluene diisocyanate are used.

It is also a degradation product of polyurethane materials produced using toluene diisocyanate.  

Its reaction with benzenediazonium chloride gives the cationic azo dye Basic Orange 1.   Condensation of 2,4-diaminotoluene with acetaldehyde gives the acridine dye called Basic Yellow 9.

Toxicity
Aromatic amines in general often are classed as toxic and so the toxicity profile of this species has been studied. It has received more in depth study in the 21st century.
