Sir Evan Jones, 1st Baronet. Sir Evan Davies Jones, 1st Baronet (18 April 1859 – 20 April 1949) was a Welsh civil engineer and politician.

The son of a sea captain, he was brought up in Fishguard and studied at the University of Bristol.  He qualified as a civil engineer and was involved in the building of the Severn Tunnel and the Manchester Ship Canal.  He became a partner in Topham, Jones, & Railton, a successful engineering firm that obtained many government contracts and worked on the Aswan Dam among other projects.

Jones served in World War I as a major in the Royal Engineers; two of his three sons were killed in the war.  From 1917 he was Petrol Controller and Commissioner for Dyes under the Board of Trade, and was created a baronet in the same year.  As a Coalition Liberal, he was MP for Pembrokeshire from December 1918 to October 1922.  In 1918 he became Chairman of the Road Transport Board, and in 1919 he was appointed Controller of Coal Mines.  In 1926 he became chairman of Pembrokeshire County Council, and was both High Sheriff (1911) and Lord Lieutenant (1932) of his native county of Pembrokeshire. He was involved in the administration of the Church in Wales, National Library of Wales and University of Wales at various times. Evan Davies Jones collected Welsh bookplates as a hobby.

Cyanuric fluoride. Cyanuric fluoride or 2,4,6-trifluoro-1,3,5-triazine is a chemical compound with the formula (CNF)3. It is a 
colourless, pungent liquid. It has been used as a precursor for fibre-reactive dyes, as a specific reagent for tyrosine residues in enzymes, and as a fluorinating agent.

It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.

Preparation and reactions

Cyanuric fluoride is prepared by fluorinating cyanuric chloride. The fluorinating agent may be SbF3Cl2, KSO2F, or NaF.

Cyanuric fluoride is used for the mild and direct conversion of carboxylic acids to acyl fluorides:

Other fluorinating methods are less direct and may be incompatible with some functional groups.

Cyanuric fluoride hydrolyses easily to cyanuric acid and it reacts more readily with nucleophiles than cyanuric chloride. Pyrolysis of cyanuric fluoride at 1300 °C is a way to prepare cyanogen fluoride:
(CNF)3 → 3 CNF.

San Antonio and Mexican Gulf Railroad. The San Antonio and Mexican Gulf Railroad (SA&MG) was a railroad set up in 1850 to connect the city of San Antonio to the Gulf of Mexico.  The railroad survived the Civil War and merged with the Indianola Railroad into the Gulf, Western Texas and Pacific Railway in 1871.

History of the road
The SA&MG was chartered on September 5, 1850, with plans to connect Lavaca, Texas, later changed to Port Lavaca, Texas to San Antonio. Trackwork began in 1856, and a line was completed to Victoria, Texas in April, 1861, when the Civil War broke out. Among the founders of the railroad were German-born railroad engineer Gustav Schleicher and Joseph E. Johnston who was an army officer stationed in San Antonio, who would later be a General in the Confederate army.

To facilitate the construction of a railroad from the Gulf to San Antonio, the SA&MG received  of land from the State.

During the Civil War
Confederate General John B. Magruder ordered the destruction of the San Antonio and Mexican Gulf to prevent its falling into the hands of enemy forces.  The railroad was rebuilt by the United States government in 1865-66.

End of the road
The San Antonio and Mexican Gulf never did connect to the Gulf coast, stopping short in Victoria. On August 4, 1870, the Texas legislature authorized the consolidation of two rail lines, the Indianola Railroad Company and the San Antonio and Mexican Gulf Railroad Company, into a new corporation to be called the Gulf, Western Texas and Pacific Railway.

Clarence Hansell. Clarence Weston Hansell (January 20, 1898 – ) was an American research engineer who pioneered investigation into the biological effects of ion air. He was granted over 300 US patents, including, in the 1930s, a precursor to the modern ink jet printer that could print 750 words a minute, its data received via radio telegraph. Only Thomas Edison held more patents.

Life and education
Hansell was born in Medaryville, Indiana on January 20, 1898. He graduated from Purdue University with a Bachelor of Science degree in electrical engineering in 1919. He was awarded an honorary Doctorate of Electrical Engineering in 1952.

Career
Hansell founded the RCA Radio Transmission Laboratory at Rocky Point, New York, Long Island in 1925, and headed the lab for over 30 years.
He was also involved in radio and fiber optics research and suggested the invention of polarized sunglasses.

His interest in the biological effects of ionized air was spurred in 1932 when he noticed that the moods of one of his colleagues at Rocky Point Laboratory swung in response to the ions being generated by their equipment. He noted that when the equipment generated negative ions, his colleague's mood was upbeat. Conversely, positive ions generated a downbeat mood. Hansell researched the therapeutic possibilities of negative ions throughout his life.  Current scientific studies support his findings, and negative ion therapy may be useful in alleviating depression in some people.

He died in 1967. His papers are kept at State University of New York, Stony Brook.

OLPC XS. The OLPC XS (often spoken as "School Server") is a Linux-based OS (a Fedora Linux-based distribution) designed to be installed on generic low-to-midrange mildly ruggedized servers. Initial plans of building a custom server geared for the role have been postponed, OLPC however offers hardware recommendations for the system, and plans to support the XO laptops running as a server for very small schools.

OLPC XS can provide children's XO laptops and their Sugar Learning Platform with network connectivity for backups, anti-theft leases, web browsing, system, content updates, asynchronous collaboration tools such as Moodle, etc.

Projected specifications 

The (currently on hold) plans call for an energy-efficient design that does not require moving parts for basic functionality. It will be mildly ruggedized.

The XS Server's CPU is a PowerPC, the MPC7447A from Freescale, with AltiVec support.

The system will boot from flash memory, which is far less likely to fail than a hard disk. Hard disks will be provided for storing a library of local content and for making backups of the children's data. The XS is intended to ship with one hard disk installed, and a second to serve as either a spare or for increased capacity. The second is not installed by default because this would consume extra power.

There will be three 802.11s wireless mesh connections. Each will be a USB device with a 3-meter (10 foot) cable, allowing good antenna placement (high, unobstructed) and good server placement (dry, secure).

Sliver (textiles). A sliver () is a long bundle of fibre that is generally used to spin yarn. A sliver is created by carding or combing the fibre, which is then drawn into long strips where the fibre is parallel. When sliver is drawn further and given a slight twist, it becomes roving.

Worsted textiles differ from woolen textiles in that, after carding, they are subjected to gilling, a process to make sure the sliver has a more uniform linear weight, and lubricants are added.

Soldier 2025. Soldier 2025 is a United States Army research and development project to create an advanced, high-tech combat uniform for U.S. infantry soldiers. The features of this outfit include nanotechnology, built-in sensors, and physical augmentations.

The ACU

Nanotechnology
Chameleonic camouflage - Technology embedded in the fabric of the uniform, most likely chemical receptors, would change color autonomously to blend in with the surrounding environment. This fabric is black when inactive.
Liquid armor - The fabric might also be treated with shear thickening fluid, a mix of polyethylene glycol and nanoscale glass particles. This mix would function like chainmail, flexible with low speed motion such as running, but hard and solid against high speed motion such as that of a bullet impact, preventing serious injury or death. The technology has already proven effective when combined with Kevlar armor.

Sensory equipment
Internal sensors - Thermal sensors monitoring both the environment and the soldier would automatically adjust the temperature of the uniform, keeping the wearer as comfortable as possible. Other sensors would detect injuries, the intake of harmful chemicals, and other physical harm, and built-in medical equipment would administer treatment as best able.
Situational awareness - A front-mounted video camera, vision aides (such as night vision sensors) and sound detectors providing three-dimensional audiological hearing would be embedded in the uniform's helmet. The face visor would act as a heads-up display, voice-activated to show ground maps, locations of fellow troops, and other needed information.
Communication - Real-time transmission would allow home base to see and hear everything the soldier does. This allows for provisions such as interlingual translation or sudden change of orders.

Augmentations
Internal respirator - A breathing device built into the helmet eliminates the need for gas masks.
XO Muscles - An exoskeletal structure on the legs permits the wearer to carry two to three times their body weight and feel only one time their body weight, increasing effective speed and endurance. No such enhancement is built into the arms or main body.

Projections
Soldier 2025 was showcased at the 24th Army Science Conference in 2024. While still in its conceptual phases, it was stated soldiers should be able to don combat uniforms similar to the showcased idea by the year 2025, as implied by the name of the project.

Possible termination
Some sources state that Soldier 2025 is part of the Land Warrior program, which was terminated in 2007, and this project was terminated along with it. However, the connection between the two is unclear at this time and requires confirmation.

Slope deflection method. The slope deflection method is a structural analysis method for beams and frames introduced in 1914 by George A. Maney. The slope deflection method was widely used for more than a decade until the moment distribution method was developed. In the book, "The Theory and Practice of Modern Framed Structures", written by J.B Johnson, C.W. Bryan and F.E. Turneaure, it is stated that this method was first developed "by Professor Otto Mohr in Germany, and later developed independently by Professor G.A. Maney". According to this book, professor Otto Mohr introduced this method for the first time in his book, "Evaluation of Trusses with Rigid Node Connections" or "Die Berechnung der Fachwerke mit Starren Knotenverbindungen".

Introduction 
By forming slope deflection equations and applying joint and shear equilibrium conditions, the rotation angles (or the slope angles) are calculated. Substituting them back into the slope deflection equations, member end moments are readily determined. Deformation of member is due to the bending moment.

Slope deflection equations 

The slope deflection equations can also be written using the stiffness factor  and the chord rotation :

Derivation of slope deflection equations 
When a simple beam of length  and flexural rigidity  is loaded at each end with clockwise moments  and , member end rotations occur in the same direction. These rotation angles can be calculated using the unit force method or Darcy's Law.

Rearranging these equations, the slope deflection equations are derived.

Equilibrium conditions

Joint equilibrium 
Joint equilibrium conditions imply that each joint with a degree of freedom should have no unbalanced moments i.e. be in equilibrium. Therefore,

Here,  are the member end moments,  are the fixed end moments, and  are the external moments directly applied at the joint.

Shear equilibrium 
When there are chord rotations in a frame, additional equilibrium conditions, namely the shear equilibrium conditions need to be taken into account.

Example 

The statically indeterminate beam shown in the figure is to be analysed.
Members AB, BC, CD have the same length .
Flexural rigidities are EI, 2EI, EI respectively.
Concentrated load of magnitude  acts at a distance  from the support A.
Uniform load of intensity  acts on BC.
Member CD is loaded at its midspan with a concentrated load of magnitude .
In the following calculations, clockwise moments and rotations are positive.

Degrees of freedom 
Rotation angles , , , of joints A, B, C, respectively are taken as the unknowns. There are no chord rotations due to other causes including support settlement.

Fixed end moments 
Fixed end moments are:

Slope deflection equations 
The slope deflection equations are constructed as follows:

Joint equilibrium equations 
Joints A, B, C should suffice the equilibrium condition. Therefore

Rotation angles 
The rotation angles are calculated from simultaneous equations above.

Member end moments 
Substitution of these values back into the slope deflection equations yields the member end moments (in kNm):

William E. Sawyer. William Edward Sawyer (c. 1850 – May 15, 1883) was an American inventor whose contribution was primarily in the field of electric engineering and electric lighting.

His primary inventions included:
 Telegraph apparatus for cable use (March 31, 1874)
 Automatic and autographic telegraph and circuit (February 2, 1875)
 Electric engineering and lighting apparatus and system (August 14, 1877)
 Device for effecting the static discharge in autographic telegraphy (November 6, 1877)
 Electric switch (June 29, 1880)
 Electrical safety device for elevators (July 6, 1880)

A 1920 article in The New York Times described him as best known for pioneering the development of the incandescent light.
In partnership with Albon Man (June 29, 1826- February 18, 1905) he founded Electro-Dynamic Light Company to produce incandescent lamps. From 1879 thorough 1885 the company successfully defended his patents against the interests of the Edison company. The patent was controlled by the Thomson-Houston Electric Company until 1888 when Westinghouse Electric bought the company producing the lamp, Consolidated Electric Light. Sawyer-Man based 'stopper' lamps, although not as long lasting as the Edison lamp, did allow Westinghouse to successfully illuminate the Chicago World's Columbian Exposition of 1893. The Sawyer-Man company was eventually purchased by the Westinghouse Corporation and became the Westinghouse lighting division.
