Equitable Life Building (Los Angeles). The  Equitable Life Building is a  International style skyscraper in the Koreatown neighborhood of Los Angeles, California. It was completed in 1969 and has 34 floors. It is tied with the Los Angeles City Hall for the 43rd-tallest building in Los Angeles. Welton Becket & Associates designed the building for the Equitable Life Insurance Company. The facade is made of precast concrete that was sandblasted to expose the beige Texas limestone aggregate.

The lobby of the Equitable Life Building hosts art in its vitrines. This space is called Equitable Vitrines. These vitrines have hosted art including Jennifer Moon's Will You Still Love Me: Learning to Love Yourself, It Is The Greatest Gift of All in 2014-2015. In an interview with Ocula Magazine, Equitable Vitrines founders Ellie Lee and Matt Connolly explained that they realised through negotiations with the building's management, 'bureaucrats, artists, and tenants—each required a different way of thinking and speaking about what art is and what it can or should do.'

Since March 2, 2015, the Equitable Life Building has served as the chancery of the Philippine Consulate General in Los Angeles, occupying part of its fifth floor.

In popular culture 
The tower has been featured in Grand Theft Auto V, although the in-gane model differs from the Equitable Life Building.

Heinkel HD 39. The Heinkel HD 39 was a special-purpose cargo aircraft developed in Germany in the 1920s to distribute the Berlin newspaper B.Z.. It was a conventional single-bay biplane with staggered wings of equal span, and a fuselage that nearly filled the interplane gap. The pilot sat in an open cockpit, and the undercarriage was of fixed, tailskid type with divided main units. The sole example of the type was built after Ernst Heinkel found out, by chance, that B.Z. required such an aircraft and had ordered two machines from Albatros. Heinkel convinced publisher Ullstein-Verlag to purchase a third aircraft from his firm.

The design was based on the HD 27 mail plane, and had a specially-designed payload bay to carry newspapers in 50 kg (110 lb) bundles. 10 separate compartments in the bay could be individually opened in flight in order to air-drop newspapers in places where the HD 39 could not land.

The HD 39 entered service alongside two Albatros L 72s in April 1926 and remained in Service until 1931, when distribution of B.Z. by air was taken over by Deutsche Luft Hansa.

Heinkel HD 40. The Heinkel HD 40 was a special-purpose cargo aircraft developed in Germany in the 1920s to distribute the Berlin newspaper B.Z.. The success of Heinkel's previous design for the publisher, the HD 39, led to the order of a similar aircraft with greater capacity, and Heinkel responded with a machine of similar layout, but considerably enlarged. Like the HD 39, it was a conventional single-bay biplane with staggered wings of unequal span, and a fuselage that nearly filled the interplane gap. The pilot sat in an open cockpit, and the undercarriage was of fixed, tailskid type with divided main units. The wings were of wooden construction, while the fuselage was built from welded steel tube skinned in plywood.

In addition to its newspaper-carrying cargo bay, the HD 40 was fitted with another compartment that could be quickly transformed between carrying extra cargo and carrying up to eight reporters or passengers. After only six months' service, the aircraft was destroyed in a crash following the failure of its engine.

Urriðafoss. Urriðafoss (, "sea trout waterfall") is a waterfall located in the river Þjórsá in southwest Iceland. With a flow rate of 360 m³/s, it has the highest average water flow of any waterfall in Iceland, and the second highest in Europe behind the Rheinfall.

The Fossafélagið Títan company was given permission in 1927 to build a power plant in Urriðafoss in connection with a railway to Reykjavík from the waterfall.
It did not happen but now Landsvirkjun is planning to build hydropower stations on the lower part of Þjórsár river, at Urriðafoss and Núpur.

The proposed Urriðafoss Power Plant is expected to have a capacity of approximately 125 MW and a power-generating capacity of  930 GWh per year. The powerhouse will be underground and a tunnel leading from the powerhouse will open out into Þjórsá river  below Urriðafoss waterfall. The waterfall is expected to disappear if the powerhouse is built.  Local residents in the area are protesting against the construction in an effort to save Urriðafoss.

PZL M-17. The PZL M-17 "Duduś Kudłacz" (initially EM-5A) was a Polish twin-boom pusher general aviation and trainer aircraft of 1977, which remained a prototype.

Design and development
The aircraft was an amateur design of a team of students of Warsaw University of Technology (Politechnika Warszawska) led by Edward Margański. It had an unorthodox layout of a pusher with twin booms and very streamlined fuselage. A crew of two sat side by side, and had double controls. A tricycle landing gear was retractable.

The plane was designed in 1969–1971. At the design stage it was designated EM-5A (EM for Margański) and nicknamed Duduś Kudłacz (Hairy Duduś). The aircraft factory PZL-Mielec in Mielec got interested in the design and took over its development, under a designation PZL M-17. The design was modified there with help of Margański, plastic and duralumin construction was changed to riveted duralumin, and a less powerful engine.

The only prototype was flown on 7 July 1977 by S. Wasil. It was not produced in series. In 1979 the prototype was given to Rzeszów University of Technology. A shortcoming of a streamlined fuselage was a cramped cockpit, the crewmen were half-laying in a similar way, as in gliders.

The plane was a mid-wing monoplane. It had a two-blade wooden propeller and a 310-liter fuel tank .

Kawasaki Ki-28. The , World War II Allied reporting name "Bob", was an experimental fighter aircraft designed for the Imperial Japanese Army and meant as a replacement for the Kawasaki Ki-10. It flew in 1936 but was never produced for actual use, as the Army chose the Nakajima Ki-27.

Design & Development
The Ki-28 was initially produced by Kawasaki Kōkūki Kōgyō K.K. in response to Japanese Army specifications for a fighter to replace the existing Kawasaki Ki-10. In mid-1935, Kawasaki, Mitsubishi, and Nakajima were instructed to build competitive prototypes. The Kawasaki design was based on its earlier but unsuccessful Ki-5. It was a low-wing cantilever monoplane of all-metal construction, except for fabric-covered control surfaces, with a conventional tail unit, fixed tailskid landing gear, and powered by a  Kawasaki Ha 9-II-Ko liquid-cooled inline V12 engine.

Service trials proved that the Kawasaki Ki-28 was the fastest of the three contenders, but the Nakajima Ki-27 was by far the most maneuverable and had the lowest wing-loading. On this basis, the Ki-27 was selected by the Imperial Japanese Army Air Force. Despite losing to the Ki-27, the Ki-28 provided Kawasaki with valuable experience, which would later help with development of the Kawasaki Ki-60 and Kawasaki Ki-61 fighters.

Mistakenly believing the Ki-28 to have entered production in Japan as the Army Type 97 Fighter, the Allies assigned it the reporting name "Bob" during World War II.

Richard Meyer (mathematician). Richard Ernst Meyer (23 March 1919 – 16 January 2008) was a mathematician and engineer.

Born in Berlin, Germany, Meyer received his PhD in aeronautical engineering from ETH Zürich in 1946. He worked at the University of Manchester and in 1953, he got a job as a senior lecturer in aeronautical engineering at the University of Sydney. He studied turbines, which led him to the research of supersonic aeronautics and the theory of characteristics. Meyer did both theoretical and experimental research; he set up a supersonic laboratory in Australia. He was elected into the Australian Academy of Science in 1956.

In 1957, Meyer moved to the department of applied mathematics at Brown University. By this time, he had also become interested in the theory of water waves. Additionally, he looked into theoretical aspects of hyperbolic and singular partial differential equations and asymptotics. Meyer became a professor of mathematics at the University of Wisconsin–Madison in 1964, where he worked until he was named professor emeritus in 1994.

Meyer died on 16 January 2008.

Knee scooter. A knee scooter or knee walker is a two-, three- or four-wheeled alternative to crutches or a traditional walker as an ambulation aid. It is known by many other names, including knee coaster, knee cruiser, knee caddy, orthopaedic scooter, or leg walker.

Over the years, it has taken on many forms—from small-wheeled devices suitable for indoor use, to larger, sturdier units capable of use outside on grass or paved surfaces. Today’s version is usually a lightweight, foldable design that, with the knee flexed, supports the shin of the unusable limb. The opposite foot makes contact with the floor or ground, providing propulsion.

Operation
The objective of the scooter is to create a safe, comfortable, and easy-to-maneuver alternative to the traditional crutch. Prior to its introduction, those experiencing foot surgery, bunionectomies, gout, below-the-knee amputations, diabetic ulcers and wounds, as well as foot sprains or fractures, had no choice but to limit activity during rehabilitation. Their only options were crutches, a traditional walker, a wheelchair, or bed rest.

The scooter does have limitations that may make it unsuitable for some patients, including those with leg injuries above or near the knee. It cannot navigate stairs, and is significantly heavier and more difficult to load into a vehicle than crutches.

Rental
As knee scooters are often used while the user recovers after surgery, they are often rented for a short period of time, usually about four weeks. While a Medicare E0118 code may have been present in the past for dealers to provide this to patients/beneficiaries, as changes are made to funding, many dealers have the option of renting these products directly for a short-use period. Due to complexities, costs of renting (if the injury is longer than typical), and possible inconvenience of return, some choose to simply purchase this product instead.

Stanford University Network. The Stanford University Network, also known as SUN, SUNet or SU-Net is the campus computer network for Stanford University.

History
Stanford Research Institute, formerly part of Stanford but on a separate campus, was the site of one of the four original ARPANET nodes. Later ARPANET nodes were located in the Stanford Artificial Intelligence Laboratory, the Computer Science Department, and the Stanford University Medical Center. In late 1979, the Xerox Palo Alto Research Center donated equipment including Xerox Alto computers, a laser printer, and file server connected by Ethernet local area network technology.

A router based on the PDP-11 computer from Digital Equipment Corporation with software from MIT was used to connect the Ethernet to the ARPANET. The PARC Universal Packet protocol was initially used on the local parts of the network, which was the experimental version of Ethernet with a data rate under 3 megabits/second. As the TCP/IP protocols evolved through the 1980s, a TCP/IP network was built on the main campus, extending to other departments, and connecting many other computers. This network was called the Stanford University Network or SUN. Today, the campus network is referred to as SUNet.

Andy Bechtolsheim, a Stanford graduate student at the time, designed a SUN workstation for use on the network in 1980. It was inspired by the Alto, but used a more modular design powered by a Motorola 68000 processor interfaced to other circuit boards using Multibus. The workstations were used by researchers to develop the V-System and other projects. Bechtolsheim licensed the design to become the basis of the products of Sun Microsystems (whose name was a pun based on the SUN acronym).

The CPU board could be configured with Bechtolsheim's experimental Ethernet boards, or commercial 10 megabit/second boards made by 3Com or others to act as a router. These routers were called Blue Boxes for the color of their case. The routers were developed and deployed by a group of students, faculty, and staff, including Len Bosack who was in charge of the computer science department's computers, and Sandy Lerner who was the Director of Computer Facilities for the Stanford University Graduate School of Business. All told there were about two dozen Blue Boxes scattered across campus. This original router design formed the base of the first Cisco Systems router hardware products, founded by Bosack and Lerner (who were married at the time).

The original router software was called NOS, Network Operating System, written by William Yeager, a staff research engineer at Stanford's medical school. Distinguishing features of NOS were that it was written in C and that it was multi-tasking capable; this allowed additional network interfaces and additional features to be easily added as new tasks. NOS was the basis of Cisco's IOS operating system. In 1987, Stanford licensed the router software and two computer boards to Cisco, after investigations by Stanford staff members such as Les Earnest.
