Let's Get Together (short story). "Let's Get Together" is a science fiction short story by American writer Isaac Asimov.  It was originally published in the February 1957 issue of Infinity Science Fiction, and included in the collections The Rest of the Robots (1964) and The Complete Robot (1982).  The robots in this tale are very different from Asimov's norm, being quite willing to work as war machines.  The tale is also based on a continuation of Cold War hostility, rather than the peaceful unified world of most of the robot stories.

Plot summary
The Cold War has endured for a century and an uneasy peace between "Us" and "Them"  exists. A secret agent arrives in America from Moscow with the story that robots identical to humans in appearance and behaviour have been developed by Them and that ten have already been infiltrated into America. When they get together, they will trigger a nuclear-level explosion (they are components of a total conversion bomb).

A conference of "Our" greatest minds in all the branches of natural science is hastily convened to decide how to detect these robots and how to catch up on this technology. Almost too late, the head of the Bureau of Robotics realises that Their plan exactly anticipates this: the infiltrator robots have replaced scientists invited to this conference, and while the explosion would kill a relatively small number of people, it would precisely include "Our" top scientists, and therefore all the scientists arriving to the conference must pass a security check before they are allowed to get together.

His guess is proven correct almost immediately, as ten of the scientists en route explode via self-destruct charges. However, the Bureau head wonders how They could have realized and acted upon the discovery of the plan so quickly. The truth dawns on him; he pulls a blaster and blows the secret agent's head off. The body slumps forward leaking "not blood, but high-grade machine oil."

Satisfaction Guaranteed (short story). "Satisfaction Guaranteed" is a science fiction short story by American writer Isaac Asimov, originally published in the April 1951 issue of Amazing Stories, and included in the collections Earth Is Room Enough (1957), The Rest of the Robots (1964), and The Complete Robot (1982).

Plot summary
Robot TN-3 (also known as  Tony) is designed as a humanoid household robot, an attempt by US Robots to get robots accepted in the home. He is placed with Claire Belmont, whose husband works for the company, as an experiment, but she is reluctant to accept him. Tony realizes that Claire has very low self-esteem, and tries to help her by redecorating her house and giving her a make-over. Finally, he pretends to be her lover, and deliberately lets the neighbors see him kissing Claire, thus increasing her self-esteem. In the end, though, Claire falls in love with Tony, and becomes conflicted and ultimately depressed when he is taken back to the lab. The TN-3 robot models are scheduled to be redesigned, since US Robots thinks that they should not produce a model that will appear to fall in love with women. US Robots robopsychologist Susan Calvin dissents, aware that women may nevertheless fall in love with robots.

Adaptations
The story was adapted as an episode of the BBC television series Out of the Unknown with Wendy Craig as Claire. The complete episode is lost, although a 2m 27s extract, audio extracts and off-screen photographs exist.

In 2002, the story was adapted for the BBC Radio 4 Afternoon Play slot.

USS Frank Cable. USS Frank Cable (AS-40) is the second  built by the Lockheed Shipbuilding and Construction Company of Seattle, Washington for the United States Navy.

The ship was christened on 14 January 1978 by Mrs. Rose A. Michaelis, wife of Admiral Frederick H. Michaelis, then Chief of Naval Material.  The ship is named for Frank Cable, an electrical engineer who had worked as an electrician and trial captain for .

History

USS Frank Cable was designed as a submarine tender for s. The ship spent 1980 until 1996 as the repair ship for SUBRON 4 and 18 in Charleston, South Carolina, tending  and s. Frank Cable began decommissioning in 1996, but then was reactivated and refitted to replace  in the Western Pacific as Commander Seventh Fleet's mobile repair and support platform.

Since arriving in Guam, USS Frank Cable has visited many Western Pacific ports to support U.S. military forces. In 1997, the ship was heavily involved with the rescue and recovery efforts following the Korean Air Flight 801 crash on Guam, and also in the recovery and clean-up efforts following Typhoon Paka. From 1980 to 2003, USS Frank Cable garnered many awards as a unit of both the U.S. Atlantic and Pacific Fleets, including seven Meritorious Unit Commendations, nine Battle Efficiency "E" awards and three Golden Anchor Awards. Frank Cable'''s most recent recognition was a Humanitarian Service Medal for support provided in recovery efforts on Guam following Super Typhoon Pongsona in 2002.

USS Frank Cable is most recently known for a sailor, MMA2 Slicer who saved a baby in 2017.

USS Frank Cable held a wreath-laying ceremony after departing Jakarta on 25 July 2022 to honor the 53 Indonesian Sailors who lost their lives aboard the KRI Nanggala which sunk on 21 April 2021 off the coast of Bali.

Dakin–West reaction. The Dakin–West reaction is a chemical reaction that transforms an amino-acid into a keto-amide using an acid anhydride and a base, typically pyridine. It is named for Henry Drysdale Dakin and Randolph West. In 2016 Schreiner and coworkers reported the first asymmetric variant of this reaction employing short oligopeptides as catalysts.

With pyridine as a base and solvent, refluxing conditions are required. However, with the addition of 4-dimethylaminopyridine (DMAP) as a catalyst, the reaction can take place at room temperature.

With some acids, this reaction can take place even in the absence of an α-amino group.

This reaction should not be confused with the Dakin reaction.

Reaction mechanism
The reaction mechanism involves the acylation and activation of the acid 1 to the mixed anhydride 3.  The amide will serve as a nucleophile for the cyclization forming the azlactone 4.  Deprotonation and acylation of the azlactone forms the key carbon-carbon bond.  Subsequent ring-opening of 6 and decarboxylation give the final keto-amide product.

General ketone synthesis
Modern variations on the Dakin–West reaction permit many enolizable carboxylic acids – not merely amino acids – to be converted to their corresponding methyl ketones.  For example, β-aryl carboxylic acids can be efficiently converted to β-aryl ketones by treatment of an acetic anhydride solution of the acid with catalytic N-methylimidazole.  This reactivity is attributed in part to generation of acetylimidazolium, a powerful cationic acetylating agent, in situ.

Eugène Bourdon. Eugène Bourdon (1808–1884) was a French watchmaker and engineer. He is the inventor of the Bourdon tube pressure gauge for which he obtained a patent in 1849.

Biography
Eugène Bourdon was born in Paris on 8 April 1808, the son of a silk merchant. From elementary school, he showed an interest in mechanical devices. His father sent him to Nuremberg for 2 years to learn German. Back in Paris, he assisted his father in his business until his father died in 1830. Eugène then worked in an optician's shop until 1832, when he set up his own workshop.

Eugène specialized in scientific instruments and model steam engines. While searching for a mechanism to measure gas pressure, without the use of a mercury manometer, he imagined using the bending of a circular tube made of a metal with good elastic properties. From this he developed the Bourdon tube pressure gauge, patented in Paris on 18 June 1849, and he granted a licence to the workshops of Felix Richard (1809-1876). His invention was crowned with the gold medal at the World's Fair in 1849. Two years later, at the World's Fair in 1851, he was awarded the Council Medal, shared with his competitor, Lucien Vidi.

Death
Bourdon died on 29 September 1884 and is buried in the Père Lachaise Cemetery.

Breaker (hydraulic). A breaker is a powerful percussion hammer fitted to an excavator for demolishing hard (rock or concrete) structures. It is powered by an auxiliary hydraulic system from the excavator, which is fitted with a foot-operated valve for this purpose. Additionally, demolition crews employ the hoe ram for jobs too large for jackhammering or areas where blasting is not possible due to safety or environmental issues.

Breakers are often referred to as "hammers", "peckers", "hoe rams" or "hoe rammers". These terms are popular and commonly used amongst construction/demolition workers. The first hydraulic breaker, Hydraulikhammer HM 400, was invented in 1967 by German company Krupp (today German company Atlas Copco) in Essen.

Engineers Without Borders (Australia). Engineers Without Borders Australia (EWB) is an Australian non-profit organisation with 20 active chapters, operating nationally and internationally with the published aim of improving the quality of life of disadvantaged communities through education and the implementation of sustainable engineering projects. EWB Australia was established in 2003 by a group of engineers from Melbourne who were motivated to take action on the developmental front through engineering.

In its declaration of aims on its website, EWB Australia outlines four principal areas of focus:
 Clean Water, Sanitation and Hygiene 
 Appropriate Housing 
 Clean Energy
 Digital Access

EWB espouses a strengths-based approach  to sustainable development and advocates the creation of systemic change through humanitarian engineering. The EWB declares support for the UN Sustainable Development Goals, whose 17 goal areas it regards as replacing the Millennium Development Goals, using them as part of the framework through which it operates in partnership with developing communities.

The organisation offers assistance to entrepreneurs, ranging from problem identification to the design, implementation and support of solutions, with an emphasis on education and training.  EWB engages with engineering students, professionals in the industry as well as the broader community in three key areas:  Programs (Projects), Education and Advocacy.

In its 2005 Conference held at the University of Melbourne, "necessary steps and actions to foster effective development at the grass roots, and identify the social, cultural, economic, and environmental aspects of development work" were tabled for debate.  At its Engage 2009 National Conference, prominent reporter Eric Campbell gave a talk entitled 'Reporting on the World'. The 2011 Conference was held at Fremantle with a focus on "undergraduate engineering experience, with engineering academics from all around the world presenting on their research and practice".

In 2017 EWB granted an Innovation Award to students at the University of Canterbury (New Zealand)

In Financial Year 2019, EWB reported AUD$4.6mil in income.

Risk (short story). "Risk" is a science fiction short story by American writer Isaac Asimov, first published in the May 1955 issue of Astounding Science Fiction, and reprinted in the collections The Rest of the Robots (1964) and The Complete Robot (1982).

The story is a sequel to "Little Lost Robot". It is set in the same location, but involves a different positronic robot – one of the few in Asimov's stories to have neither a serial number nor nickname.

Plot summary
The researchers at Hyper Base are ready to test the first hyperspace ship. Previous experiments were successful in transportation of inert objects, but all attempts to transport living creatures have led to complete loss of higher brain function. As such, the ship has a positronic robot at the controls, since a robot is more expendable than a human, and its brain can later be precisely analyzed for errors to determine the cause. The ship fails to function as planned, and Susan Calvin persuades Gerald Black, an etherics engineer (who had also appeared in "Little Lost Robot"), to board the ship in order to locate the fault.

As Calvin suspects, Black finds that the fault lies with the robot, which, as a result of imprecise orders, has damaged the controls of the ship. They realize that the precise and finite robot mind must be compensated for by human ingenuity.

Lenny (short story). "Lenny" is a science fiction short story by American writer  Isaac Asimov, originally published in the January 1958 issue of Infinity Science Fiction, and included in the collections The Rest of the Robots (1964), The Complete Robot (1982), and Robot Visions (1990).

Plot summary
U.S. Robots is planning the production of the LNE series of robots, which are designed for boron mining in the asteroid belt. After a technician neglects to lock a terminal, a factory tourist accidentally reprograms the prototype LNE, wiping clean the structure of the robot's brain, and rendering it a baby in all effects.

Robopsychologist Susan Calvin experiments with it, in the process naming it "Lenny" (and developing maternal feelings for it), and after a month, has been able to teach it a few simple words and actions. She gets emotionally attached to Lenny and realizes that robots can be built that are able to learn, instead of being built for a fixed and specific purpose.

Complications arise when Lenny, unaware of its own force, breaks the arm of a computing technician, which is about to cause widespread "robots attacking humans" panic. However, Susan Calvin manages to exploit the sense of danger to add a new thrill of robotic investigation, just as happens with space exploration or radiation physics.

Harlan Ellison's screenplay
The Harlan Ellison screenplay I, Robot, based on Asimov's Robot stories, would greatly expand Lenny's role and link "Lenny" to "Evidence". The latter short story concerns Stephen Byerley, a politician who has been accused of being a robot and therefore ineligible for office. The original short story never explicitly states whether or not Byerley is a human. However, the screenplay reveals that Byerley is not just a robot, but Lenny in disguise.

Access 5. Access 5 was a national project run by NASA in collaboration with industry, the Federal Aviation Administration (FAA), and the United States Department of Defense (DoD), in order to introduce high altitude, long endurance (HALE) remotely operated aircraft (ROA) for routine flights in the National Airspace System (NAS). It was the first project in the United States to formally attempt to integrated unmanned aircraft into the national airspace system (NAS).  The primary objective was to open up airspace for commercial unmanned aviation.  Access 5 commenced in May 2004 and was slated to run for five years. The project received initial funding in the amount of $101M from NASA and guarantees of support from the ROA industry. It was managed out of Dryden Flight Research Center. The program was managed by Jeff Bauer out of NASA Dryden and R. Scott Dann, a General Atomics program manager who filled the role of industry director.  R. Scott Dann was also the founder and first president of the UAV National Industry Team (UNITE). A good portion of the leadership on the Access 5 program were involved in the NASA ERAST (Environment Research and Sensor Technology) program, another pioneering program in UAS development.     

The goal of Access 5 was to enable what government and industry leaders believe will ultimately be a robust civil and commercial market for HALE ROA. The current lack of ready access to the NAS inhibits investment in ROA commercialization and the ability of users to obtain cost-effective ROA services. Access 5 seeks to remove the barriers to aviation's most compelling new offering in decades.  Access 5 was the first organized effort to advanced UAVs into the national airspace system (NAS).  The members of the Access 5 project developed the first comprehensive plan for the integration of UAS into the NAS.  The plan included all the tasks that would have to be accomplished in four categories, 1.) UAS Technology, 2.) Aviation Infrastructure, 3.) Policy and Regulation, and 4.) Implementation. The plan was later resurrected in the first FAA UAS Aviation Rule Committee.  The work conducted by UNITE/Access 5 was pioneering and  the precursors to all future efforts to introduce UAS into the NAS including the formation of the first FAA UAS Aviation Rule Committee (ARC) led by Jim Williams (FAA) and chaired by R. Scott Dann (General Atomics).

The project was terminated on February 28, 2006 after a reorganization of NASA's research programs to focus on returning man kind to the Moon. The cancellation of the program led members of the UAV National Industry Team (UNITE) alliance, which includes Boeing, General Atomics, Lockheed Martin, Northrop Grumman, AeroVironment, and Aurora Flight Sciences to advocate for a new national plan in testimony before the United States Congress.
