Richard L. Cevoli. Richard L. Cevoli (October 24, 1919 – January 18, 1955) served as a United States Naval Aviator and carrier fighter pilot during World War II and the Korean War. Decorated for valor in both conflicts, Cevoli reached the rank of Commander before he was killed in a plane crash in 1955.

Pre-military
Richard Leo Cevoli was a lifelong resident of East Greenwich. He graduated from La Salle Academy and later from Rhode Island State College, where he earned a degree in civil engineering. He worked for the engineering firm, Merritt, Chapman & Scott, and joined the Navy a month after the attack on Pearl Harbor.

Military career

World War II
While serving with Fighting Squadron 18 (VF-18) aboard the U.S.S. Intrepid, Cevoli and other members of the squadron strafed a Japanese battleship during the Battle of Leyte Gulf, silencing many of its guns. The following day, he scored a hit with a 500lb bomb, disabling a Japanese aircraft carrier. Cevoli is also credited with four confirmed air victories and three probables during his service with VF-18.

Korean War
From 1949 until 1951, Cevoli served as the Executive Officer in Fighting Squadron 32 (VF-32) on board the USS Leyte. In the winter of 1950, he and his pilots provided close in air support against 70,000 Chinese soldiers crossing the Yalu River and enabled 30,000 United Nations soldiers to escape encirclement. He was also division leader for Thomas J. Hudner Jr. and Jesse L. Brown. He radioed for help when Brown was shot down on 4 December 1950, during the mission for which Hudner would receive the Medal of Honor. The story of Brown and Hudner's friendship and service is the subject of Adam Makos' book Devotion, which was subsequently turned into a feature film. Thomas Sadoski was cast to play Richard Cevoli.

Post-war service
After the war, Cevoli graduated from the Naval War College. In 1954 he assumed command of Fighting Squadron 73 (VF-73) and attained the rank of Commander. He was killed during a training mission on January 18, 1955, when his F9F-6 Cougar jet crashed into a forest shortly after takeoff from Jacksonville, Florida.

Rope lock. In a theater fly system, a rope lock is a device used to prevent a rope, and the line set it controls, from moving. A rope lock is controlled by a steel handle that engages the lock when vertical and releases it when horizontal. The handle is typically red powder coated or covered by a red rubber grip. A steel, oval-shaped safety ring encircles both the rope and the handle to ensure that the lock cannot be accidentally released. Rope locks are mounted to a locking rail, which provides structural support and holds them at a convenient level for the stage crew.

Locking mechanism
Two metal cams, one stationary and one movable, are used to immobilize the rope. The position of the movable cam is controlled by the locking handle. When the handle is raised, the movable cam is pressed towards the stationary cam so as to grip the rope by compressing it between the cams. Conversely, the lock is released by lowering the handle, thus retracting the movable cam away from the stationary cam and releasing the grip on the rope. The position of the stationary cam can usually be adjusted with a socket head adjustment screw. This enables the spacing between the cams to be adjusted so that, when locked, the rope lock can accommodate ropes of different diameters.

Simple rope locks are designed to immobilize only balanced or slightly unbalanced loads; they will not hold significantly unbalanced line sets in place nor are they intended to be used for line set speed control. Most traditional rope locks are rated to hold a difference of  or less. For this reason, proper loading technique is essential for safe operation. Misuse of the rope lock is a common source of rigging accidents, especially among students. More complex rope locks are available which will prevent unlocking if the line set is excessively unbalanced. These load-sensing locks reduce the probability of accidents, but may cause inconvenient loading situations and are more expensive than simpler locks. Rope locks are also available which are designed to hold unbalanced line-sets and act effectively as a brake.

Many rope locks provide a hole that will accommodate a padlock. When a padlock is installed, the control lever is locked in the vertical orientation and the line set cannot be moved. A rope lock is typically padlocked to prevent accidental movement of the set.

Civil Aircraft Missile Protection System. Civil Aircraft Missile Protection System (CAMPS) is an infrared countermeasure against infrared-homed anti-aircraft missiles, specifically designed to defend civilian aircraft flying under  against MANPADS.  

The system was developed by Saab Avitronics, Chemring Countermeasures and Naturelink Aviation. 

The decoys use a pyrophoric substance that burns at a relatively low temperature, thereby avoiding any fire safety concerns associated with conventional pyrotechnic military flares, such as those used by a similar Israeli system.  The onboard processor uses neural network pattern recognition algorithms to classify potential threats detected by its infrared sensors.  The system was successfully demonstrated at the Overberg Test Range in March 2007.

Motunui. Motunui (large island in Māori, from Motu Nui) is a settlement in northern Taranaki, in the North Island of New Zealand. It is located on State Highway 3 close to the shore of the North Taranaki Bight, six kilometres east of Waitara.

Industry
Motunui is the location of the Motunui methanol plant, which was the largest in the world at the time of construction. It was opened in 1986 to convert natural gas to methanol, then the methanol to synthetic petrol using a process developed by Mobil. The plant was one of the Think Big projects of the Third National Government. 

The process became uneconomic in the late 1990s as a result of falling oil prices, so the synthetic petrol part of the plant was decommissioned, with petrol production ceasing in April 1999, and the plant instead produced methanol for export. Production of methanol ceased in 2004 as the approaching depletion of the Maui gas field raised gas prices. Methanol train No. 2 was recommissioned in 2008, followed by train No. 1 in 2012. Currently owned and operated by Methanex, the plant's two trains have a total annual production capacity of 2.4 million tonnes of methanol.

In 2005, an unmanned production station for the new offshore Pohokura oil/gas field was constructed immediately west of the methanol plant. This began commercial production in September 2006.

August 2004 tornado
On the morning of 15 August 2004, a rare and deadly F3 tornado struck Motunui. The tornado killed two people and injured two others when a farmhouse on Epiha Road was completely demolished. A glass house was damaged, and livestock was killed. The tornado was the strongest ever recorded in New Zealand.

Pin and hanger assembly. A pin and hanger assembly is used to connect two plate girders of a bridge.  These assemblies are used to provide an expansion joint in the bridge.  One beam (the anchor span) is set on a pier with a short section cantilevered out toward the next pier.   The other (the suspended span) begins underneath the anchor span, and has its far end resting on the next pier.  The beams have holes directly above each other.  The two holes are connected using hangers, a pair of connecting plates sandwiching the bridge girders.  A pair of large steel pins through the plates and girder webbing provide the hinges, holding up the suspended span while allowing it to move longitudinally.  Large washers are bolted to each end of the pin to retain the hangers.  Exceptionally long spans may have two sets of girders cantilevered from opposite bridge piers with a third set of girders suspended by pin and hanger assemblies from both cantilevers.

Safety concerns
Pin and hanger assemblies are considered fracture critical bridge components, meaning that the assemblies are non-redundant and failure of these systems could cause part or all of the bridge to collapse. The collapse of the Mianus River Bridge in Connecticut exposed potential flaws with pin and hanger bridges that could lead to catastrophic failures, if left unchecked.  Because of this, state departments of transportation incur costly expenses on bridges with pin and hanger assemblies, as they require constant inspection and maintenance.  As a result of these safety concerns, and advances in bridge design to allow longer spans, pin and hanger assemblies are no longer used on new bridges in the United States.

Retrofitting
Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly.  Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should the pin and hanger assembly fail.  Another redundancy is connecting the cantilevered and suspended girders at the pin and hanger assembly with welded blocks and tie rods.  Replacement options include bolted splices (gusset plates) plus shear connectors; a link slab; a ship-lap joint; and a new pin and hanger assembly with improved materials.

Composite epoxy material. Composite epoxy materials (CEM) are a group of composite materials typically made from woven glass fabric surfaces and non-woven glass core combined with epoxy synthetic resin. They are typically used in printed circuit boards.

There are different types of CEMs:

 CEM-1 is low-cost, flame-retardant, cellulose-paper-based laminate with only one layer of woven glass fabric.
 CEM-2 has cellulose paper core and woven glass fabric surface.
 CEM-3 is very similar to the most commonly used PCB material, FR-4. Its color is white, and it is flame-retardant.
 CEM-4 quite similar to CEM-3 but not flame-retardant.
 CEM-5 (also called CRM-5) has polyester woven glass core.

Micritisation. Micritisation is the activity of certain organisms in the clasts of carbonate sediments, whereby the organisms retract nutrients from the carbonate.  Micritisation is a process that falls under diagenesis of a sediment.

The organisms can be algae, fungi or bacteria.  These organisms bore small "tunnels" in the original crystals that the clasts were built from.  When the micritisation goes on long enough the process can form micritisation envelopes around the clast, especially with larger clast (such as shell fragments).

Micritisation disrupts the original crystal structure, chemical composition and structure of the clasts in the sediment.

WVA number. WVA numbers (Waren-Vertriebs-Artikel-Nummern) are a reference and assignment system for brake linings, clutch facings, brake shoes and other friction materials which will especially be used in road vehicles but also in mechanical engineering. The WVA numbering system has been developed by the "VRI-Verband der Reibbelagindustrie" (Federation of Friction Industry), Cologne / Germany. The VRI is the German Federation of Friction Industry and a member of FEMFM - Federation of European Manufacturers of Friction Materials.

Taking the dimensionally determined parameters of the friction materials into account the system assigns the differently dimensioned linings to the respective areas of application and use and accordingly offers a basis for the cooperation and for the exchange of information between manufacturers, distributors and customers.

Extensional viscosity. Extensional viscosity  (also known as elongational viscosity) is a viscosity coefficient when the applied stress is extensional stress. It is often used for characterizing polymer solutions.
Extensional viscosity can be measured using rheometers that apply extensional stress. Acoustic rheometer is one example of such devices.

Extensional viscosity is defined as the ratio of the normal stress difference to the rate of strain. For uniaxial extension along direction :

Raritan River Project. The Raritan River Project was founded by the Edison Wetlands Association (EWA) in 1995 to protect human health, quality of life, and the environment against threats, including pollution, overdevelopment, and lack of public access to waterways.

The Raritan River is the longest river solely in New Jersey, flowing through 49 municipalities, including an industrial corridor known as Central New Jersey’s “Chemical Belt”. The Raritan also flows through many of New Jersey’s 18,500 contaminated industrial sites, making it the twelfth most polluted river in U.S.

Over 200 contaminated sites are adjacent or drain into the lower Raritan River, including abandoned industrial sites, Superfund sites, old landfills, dredge dumping areas and old army arsenals.  Residents continue to be exposed to toxic waste through recreational use of the river and eating contaminated fish despite warning that it may be hazardous to their health.  The mission of the Raritan River Project is to clean up and protect the lower reaches of the Raritan River by identifying and reducing sources of contamination. The goal of the EWA is to stop the ongoing pollution, clean up the existing contamination and restore the watershed.
