Real-Time Automated Personnel Identification System. The Real-Time Automated Personnel Identification System (RAPIDS) is a United States Department of Defense (DoD) system used to issue the definitive credential within DoD.  RAPIDS uses information stored in the DoD Defense Enrollment Eligibility Reporting System (DEERS) when providing these credentials.  Used together, these two systems are commonly referred to as a DEERS/RAPIDS system or DEERS/RAPIDS infrastructure.

Objectives

RAPIDS performs the following functions:
Authenticating individuals
Capturing unique identifying characteristics
Providing a distinct identification credential

Authenticating individuals
RAPIDS ensures that DoD identification credentials are provided only to personnel with a current and appropriate affiliation with the DoD

Capture unique identifying characteristics
RAPIDS captures identifying characteristics that are unique and are used to bind an individual to the information maintained in DEERS and in line with the identifying credentials issued by RAPIDS. These include, but are not limited to:
Photographs
Fingerprints

The information is stored solely in the DEERS System. Other redundant systems or repositories shall not be utilized without compelling justification for their need.

Providing a distinct identification credential
RAPIDS provides distinct identification that is used as proof of identity and DoD affiliation. It may be used as a Geneva Convention ID in accordance with DoD Instruction 1000.13.  It also acts as the United States Uniformed Services Privilege and Identification Card to access benefits and privileges, such as usage of the commissary on military installations or receiving healthcare.

Hemacite. Hemacite is a material made from sawdust and the blood of slaughtered cattle and pigs. It was invented and patented by Dr W H Dibble of New Jersey in the last quarter of the nineteenth century. Using hydraulic pressure () and chemical compounds, blood and sawdust were transformed by Dibble's Hemacite Manufacturing Company into everything from doorknobs and roller skate wheels to cash register buttons and telephone receivers; there is even extensive use in Victorian jewellery. Hemacite was inexpensive but fell out of favor with the popularity of new plastics like Bakelite. It is quite easy to misidentify Hemacite as Bakelite.

Uses
This composition was pre-plastic, and ideal for everything from doorknobs to roller skate wheels to products such as buttons, cash register keys and jewelry. The composition of Hemacite was touted as susceptible to a high polish, impervious to heat, moisture, atmospheric changes, it acted very similarity to the material Pykrete. Hemacite was cheap to produce due to blood and sawdust both being cheap materials.

Decline
Although Hemacite is a cheap material, Bakelite was cheaper to produce, and by the early to mid-1900s the popularity of plastics like Bakelite almost entirely replaced the production of Hemacite.

Broker pattern. The broker pattern is an architectural pattern that can be used to structure distributed software systems with decoupled components that interact by remote procedure calls. A broker component is responsible for coordinating communication, such as forwarding requests, as well as transmitting results and exceptions.

Definition 

The broker pattern is an architecture pattern that involves the use of an intermediary software entity, called a "broker", to facilitate communication between two or more software components. The broker acts as a "middleman" between the components, allowing them to communicate without being aware of each other's existence.

In the broker pattern, the broker is responsible for receiving messages from one component and forwarding them to the appropriate recipient. The components that communicate through the broker are known as servers or clients. The broker may also perform additional tasks, such as filtering, modifying messages, ensuring a quality of service (QoS) (e.g. 0 for "at most once"), security, or providing additional services to the software components.

The broker pattern allows the components to remain decoupled and focused on their own responsibilities, while still being able to communicate and collaborate with other components in the system. It can also be used to reduce the number of dependencies between components, making the system more flexible and easier to maintain.

Terminology 
Broker
 Maintain a routing table of registered software components.
 Maintain a filter table to reroute the transiting messages to the right software components.
 May assure additional functionalities such as information security and quality of service.

Server
 Software components responsible for sending a message out.
 It is also referred to as a publisher.

Client
 Software components that subscribed and await a specific message.
 It can also be referred to as a consumer or subscriber.

Advantages 
Source:

 Dynamic changes, additions, deletions, and relocations of components possible.
 One source of communication with the broker, which defines the interface.
 Components do not need to know each other.

Disadvantages 
 One central component that needs to be robust and efficiently written.
 No data consistency of transmitted messages.

 RabbitMQ
 MQTT

Confusions around the pattern 
The broker pattern and publish–subscribe pattern have some similarities and are sometimes confused. Nevertheless, when it comes to the representation, there are some core differences:
 The Broker architectural pattern is represented by a Many to One to Many diagram.
 The Publish-subscribe architectural pattern is represented by a Many to Many diagram. Here, the messaging functionalities are hidden as a Cross-cutting concern.

Terre Haute, Brazil and Eastern Railroad. The Terre Haute, Brazil and Eastern Railroad was a short-line railroad that was incorporated May 1, 1987 and began operations on October 15, 1987. The TBER operated over 30 miles of the Pennsylvania Railroad's St. Louis-Indianapolis-Pittsburgh Line, which had been abandoned by Conrail in 1984 in favor of the former New York Central-Big Four St. Louis Line subdivision. The line extended from Terre Haute to Limedale and included a seven-mile branch line to the Amax Coal Company's Chinook Mine south of Brazil. 
 
The TBER interchanged with the Soo Line Railroad's Latta Subdivision, Conrail's St. Louis Line and CSX's CE&D Subdivision in Terre Haute. Traffic was an even mix of lumber, fertilizer, and plastic pellets inbound and grain, cement, and plastic pipe outbound. A tourist excursion called the Beaver Hawk Express was operated under contract between Brazil, Indiana and Limedale. Coal traffic was also anticipated but failed to materialize, as a result the line entered bankruptcy. The TBER ceased operation on December 31, 1993, and the line was dismantled.

Motive Power
The TBER operated three locomotives. 
100 an ex-Missouri Pacific EMD SW1200
101 an ex-Chicago Rock Island & Pacific EMD SW8
6999 an ex-Pennsylvania, Penn Central, Conrail EMD SD7 was owned by the proprietors of the Beaver Hawk Express and never saw service on the TBER.

Georgia Nuclear Aircraft Laboratory. The Georgia Nuclear Aircraft Laboratory, also known as AFP No. 67, for Air Force Plant 67 was a United States Air Force test facility located in the Dawson Forest in Dawsonville, Georgia. It was the site of Lockheed's lab for investigating the feasibility of nuclear aircraft. The site was used for irradiating military equipment, as well as the forest to determine the effect of nuclear war, and its effects on wildlife. The area was closed in 1971 and acquired by the city of Atlanta for a second airport, but its topography was determined to be ill-suited for an airport. Documents explaining what went on at the site remain classified. The entrance to the underground portion of the facility is accessible, but it is entirely flooded, except for a few feet of the top level. The only objects left above ground were the concrete foundations on which the buildings and reactors were placed.

Sparging (chemistry). In chemistry, sparging, also known as gas flushing in metallurgy, is a technique in which a gas is bubbled through a liquid in order to remove other dissolved gas(es) and/or dissolved volatile liquid(s) from that liquid. It is a method of degassing. According to Henry's law, the concentration of each gas in a liquid is proportional to the partial pressure of that gas (in the gaseous state) in contact with the liquid. Sparging introduces a gas that has little or no partial pressure of the gas(es) to be removed, and increases the area of the gas-liquid interface, which encourages some of the dissolved gas(es) to diffuse into the sparging gas before the sparging gas escapes from the liquid. Many sparging processes, such as solvent removal, use air as the sparging gas. To remove oxygen, or for sensitive solutions or reactive molten metals, a chemically inert gas such as nitrogen, argon, or helium is used.

Liquid chromatography
Solvents used in high-performance liquid chromatography (HPLC) are often sparged with helium.

Engineering
In biochemical engineering, sparging can remove low-boiling liquids from a solution. The low-boiling components evaporate more rapidly, so the gas bubbles remove more of them from the bulk solution containing higher-boiling components. It is an alternative to distillation, and it does not require heat.

Environmental chemistry

In environmental chemistry, air sparging is an in situ remediation technique that removes volatile pollutants from contaminated groundwater and soil.

Metallurgy
In metallurgy, gas flushing removes dissolved gases from the molten metal prior to the material being processed. For example, before casting aluminium alloys, argon bubbles are injected into liquid aluminium using a rotary degasser. The argon bubbles rise to the surface, bringing with them some of the dissolved hydrogen. The degassing step reduces the occurrence of hydrogen gas porosity. In the steel making process, this method is used very commonly for duplex steel and some high reactivity metals.

Trevor Pearcey. Trevor Pearcey (5 March 1919 – 27 January 1998) was a British-born Australian scientist, who created CSIRAC, one of the first stored-program electronic computers in the world.

Born in Woolwich, London, he graduated from Imperial College in 1940 with first class honours in physics and mathematics. He emigrated to Australia in 1945.

In a 1948 paper, published in the Australian Journal of Science, he envisaged using a digital electronic computer for providing information over a national telecommunications network:

He bet that he could make an electronic device that would be 1000 times faster than the best electronic device of the time. One of his calculators filled a small room, weighing 7 tons.

He was awarded a D.Sc. by the University of Melbourne in 1971.

In his later years he lived on the Mornington Peninsula near Melbourne.

The Pearcey Foundation and the Pearcey Award for outstanding achievement by an Australian in the ICT industry are named after him.

Water Supply (Water Quality) Regulations 1989. The Water Supply Water Quality Regulations 1989 (SI No. 1147) are regulations imposed on the England and Wales Water industry by statutory instrument. The regulations were signed jointly by Peter Walker, Secretary of State for Wales and Michael Howard who, as Minister for Water and Planning, was responsible for implementing water privatization in England and Wales during 1988/89. Most of the measures came into force on 1 September 1989, and the rest on 1 January 1990. The regulations have been superseded by several later instruments.

Revocation 
The 1989 regulations were revoked in England by the Water Supply (Water Quality) Regulations (SI 2000/3184) and in Wales by the Water Supply (Water Quality) Regulations (SI 2001/3911). Further changes were made by the Water Industry Act 1991.

Wholesomeness 
Schedule 2 of the regulations prescribes concentrations for substances that affect wholesomeness.

Wool top. Topmaking mills make wool top, a semi-processed product from raw wool. The process requires that the wool be scoured (washed) and combed and sorted. The longer fibers resulting from the process are called tops, and are in a form ready for spinning. To be closer to customers, some of the industry has moved from Australia, Europe and the US to China. Many American and British companies produce high quality wool top in from sheep wool and fiber; most work with the fleece from cleaning it to hand dying.

A topmaker is an old term for a person engaged in the process.

Nash (tugboat). Nash is a World War II U.S. Army Large Tug (LT) seagoing tugboat built as hull #298 at Jakobson Shipyard, Oyster Bay, New York as a Design 271 steel-hulled Large Tug delivered in November 1943. Originally named Major Elisha K. Henson (LT-5), in 1946 she was renamed John F. Nash by the U.S. Army Corps of Engineers. Since retirement from the Corps of Engineers, LT-5 has been renamed Major Elisha K. Henson. As of the 1992 date of its listing as a National Historic Landmark, LT-5 was believed to be one of the last functional U.S. Army vessels that participated in Normandy landings.

Service in World War II 
LT-5 sailed to Great Britain in February 1944 in anticipation of Operation Overlord, the planned allied invasion of Europe. On June 6, 1944, LT-5 sailed for Normandy with two barges as part of Operation Mulberry, in support of Overlord. Under fire, the tug ferried supplies to the landing beaches for the next month, in the process shooting down a German fighter aircraft on June 9.

After the war, LT-5 returned to the United States. Assigned to the Buffalo District of the U.S. Army Corps of Engineers in May 1946, LT-5 was renamed John F. Nash after Buffalo District's Senior Engineer and Chief Civilian Assistant for the period 1932 to 1941. From 1946 to 1989, John F. Nash served the lower Great Lakes region by assisting in the maintenance of harbors, and construction projects that included the St. Lawrence Seaway in the 1950s.

Post-military career 
Renamed Major Elisha K. Henson, she has been largely restored to her original configuration by the H. Lee White Marine Museum in Oswego, New York where she is currently on display. Tours are available Mid-May through the end of September. LT-5 was declared a National Historic Landmark in 1992.  A sister ship located at Kewaunee, Wisconsin, the  Major Wilbur Fr. Browder (LT-4), now the Tug Ludington, is a museum ship which also served the U.S. Army at D-Day and otherwise has a similar history, which was listed on the National Register in 2002.
