Yttrium(II) oxide. Yttrium(II) oxide or yttrium monoxide is a chemical compound with the formula YO. This chemical compound was first created in its solid form by pulsed laser deposition, using yttrium(III) oxide as the target at 350 °C. The film was deposited on calcium fluoride using a krypton monofluoride laser. This resulted in a 200 nm flim of yttrium monoxide.

Nordica 20. The Nordica 20 is a Canadian trailerable sailboat that was designed by B. Malta-Muller as a cruiser and first built in 1975.

The Nordica 20 is most likely a development of the Malta-Muller-designed Lynaes Senior, which was built in Denmark. The Halman 20 is a development of the Nordica 20.

Production
The design was built by Nordica Yachts, a brand of Exe Fibercraft in Canada, starting in 1975, but it is now out of production.

Design
The Nordica 20 is a recreational keelboat, built predominantly of fibreglass. It has a masthead sloop rig, a spooned plumb stem, a rounded transom, a keel-mounted rudder controlled by a tiller and a fixed long keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel.

The boat is fitted with an inboard BMW or Renault  diesel engine or an outboard motor for docking and manoeuvring. The fuel tank holds .

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee berths in the main cabin. Cabin headroom is .

The design has a PHRF racing average handicap of 276 and a hull speed of .

Operational history
The boat is supported by an active class club, Nordica Boats.

In a 2010 review Steve Henkel wrote, "... best features: The springy sheer and rounded stern on both the Nordica and Halman give them a salty look. Worst features: [They] have relatively small cockpits; more than two occupants would constitute a crowd. Perhaps that is just as well, since buoyancy aft is limited by the pinched stern; more than two occupants would push the stern down, upsetting the natural trim of the hull. Consequently the extra two berths are pretty much usable only for stowage or in harbor."

RJ Scaringe. Robert Joseph "RJ" Scaringe (born January 19, 1983) is an American entrepreneur and engineer, and the founder and CEO of electric vehicle manufacturer Rivian.

Early life and education
Robert Joseph Scaringe was born on January 19, 1983. His father, also named Robert Scaringe, is an engineer and founder of Mainstream Engineering Corporation. Scaringe grew up a car enthusiast, restoring them in his neighbor's garage. After learning of the great negative environmental effects of cars, however, he decided to focus his life on creating a more sustainable and environmentally friendly transportation system.

Scaringe grew up in Melbourne, Florida. He attended Melbourne Central Catholic High School. Scaringe received his bachelor's degree in mechanical engineering from Rensselaer Polytechnic Institute. He then received a master's degree in mechanical engineering at the Massachusetts Institute of Technology (MIT) and went on to also receive a doctorate in mechanical engineering at MIT's Sloan Automotive Lab.

Personal life
Scaringe married Meagan McGone in Michigan in August 2014. The couple have three children together.

According to Forbes, Scaringe's net worth was estimated at $3.4 billion as of April 2021, but he lost his billionaire status in March 2022 due to Rivian's declining share value.

Career
Scaringe returned to Rockledge, Florida, and founded Mainstream Motors in the year of 2009 as the sole employee. The name of the company changed to Rivian Automotive in 2011.

In November 2021, Rivian went public, listing its shares on the Nasdaq.

Scaringe is chairman of the board and has 9.5% voting power. Additionally, he has veto power over board decisions due to his 100% ownership of the company's class B shares. In total, Scaringe owns about 1.4% of Rivian.

SafetyNet. SafetyNet consists of several application programming interfaces (APIs) offered by the Google Play Services to support security sensitive applications and enforce DRM. Currently, these APIs include device integrity verification, app verification, recaptcha and web address verification.  It is an extension of AVB2.0 and dm-verity.

Attestation 

The SafetyNet Attestation API, one of the APIs under the SafetyNet umbrella, provides verification that the integrity of the device is not compromised.
In practice, non-official ROMs such as LineageOS fail the hardware attestation and thus restrict the user from using a non-compliant ROM while being able to use third-party apps (mainly banking) that require the API.
Due to this, some consider this a monopolistic practice deterring the entrance of competing mobile operating systems in the market. 

Attestation requires a network connection for Google Play Services to connect to Google servers and validate the hardware signatures. Amongst the checks, the API looks for bootloader unlock status, ROM signature and kernel strings. Upon successful checks, Google Play will mark the device as Certified.

The SafetyNet Attestation API (one of the four APIs under the SafetyNet umbrella) has been deprecated.  Google expects to fully replace it with the Play Integrity API by the end of January 2025. Like the SafetyNet APIs, the Play Integrity API is offered by Google Services and thus is not available on free Android environments (AOSP). Therefore, apps that require the API to be available may refuse to execute on AOSP builds.

EXL 100. The EXL 100 is a computer released in 1984 by the French brand Exelvision, based on the TMS 7020 microprocessor from Texas Instruments. This was an uncommon design choice (at the time almost all home computers either used 6502 or Z80 microprocessors) but justified by the fact that the engineering team behind the machine (Jacques Palpacuer, Victor Zebrouck and Christian Petiot) came from Texas instruments.
It was part of the government Computing for All plan and 9000 units were used in schools.

The design is unusual compared with similar machines of the time, as it had a separate central processing unit. Two keyboards are available: one with rubber keys and another with a more standard touch. Keyboard and joystick were not connected to the central unit by a cable but by infrared link, and are battery powered. Many extensions were available: modem, floppy disk drive and a 16 KB CMOS RAM powered by an integrated lithium battery.
Its TMS 5220 sound processor was capable of French speech synthesis, another unusual feature.

The machine came with a BASIC version on cartridge named ExelBasic.

Specifications
Release price: 3,190 French francs
 CPU: TMS 7020 at 4.9 MHz
 Graphics chip: TMS 3556 (40 x 25 character text mode, 320 x 250 pixel graphics mode, 8 colors)
 Sound: TMS 5220 (with speech synthesis in French)
 Storage: cartridge port, cassettes, optional floppy disk drive
 Memory: 34 KB RAM (2 KB RAM + 32 KB Shared VRAM), 4 to 32 KB ROM
Variants: A version with an integrated V23 modem named Exeltel was released in 1986

Compaction (textiles). Compaction (compacting) is a finishing process used to minimize shrinking in textiles. Textile products that are loosely woven or knitted shrink more, whereas tightly knitted and woven products are more stable. The structure of knitted fabrics is competitively loose and flexible. Compaction, like sanforization for woven fabric, is intended to reduce shrinkage in tube and open width Knitted textiles.

Compactor 
A compactor is a textile finishing machine that is specifically designed for compaction. Compaction has a mechanism that shrinks the fabric forcibly in order to render it shrinkproof, preventing any residual shrinking in the applied fabric. The machine has two cylinders, the delivery cylinder moves faster than the take-off cylinder. Shrinkage in textiles is an undesirable property caused by fiber properties, fabric structure and elongations caused during prior treatments.

Components 
A compactor machine is equipped with an entry, small tenter frame, steaming unit and a set of felt and rollers. It may have J Box or rolling at exit. There are Compactors with a metal shoe also (Reference: Tube-Tex.)

Functions 
Compaction results in smoother surfaces, controlled twisting, and shrinkage of the fabric. Additionally it helps in adjusting width and the GSM of the fabric by manipulating fabric density.

Harry Rehnberg. Harry Rehnberg (1910–1975) was an American chemist and businessperson most notable for being the founder of Halcon International and for inventing the revolutionary Halcon process.

Early life 

Rehnberg was born in Everett, Washington, November 21, 1910, the son of Swedish immigrants Alex Rehnberg and Helen Rehnberg.

Education 

He completed his degree in mechanical engineering at the University of Washington, Seattle.

Career

Austin Company 

His very first job out of college was at the Austin Company, where he assisted in the design and construction of tanks.

Manhattan Project 

It was during World War II that he worked on the development of the atom bomb in the Manhattan Project at Oak Ridge, Tennessee.

It was in the course of his work on the Manhattan Project, that he met Ralph Landau, with whom he would go on to collaborate in many of his future business ventures.

Halcon International 

In 1962 Ralph Landau and Harry Rehnberg discovered a novel process - the Halcon process - for converting propylene  intopropylene oxide. In the new process, hydroperoxides serve as a source of oxygen atoms, which are transferred to the olefin by metal catalysts. Propylene oxide is used in polyurethane foams and in rigid polymers. The side products of the reaction include styrene and tert-Butyl alcohol, which are also useful. The company reorganized in 1963 to form Halcon International, in preparation for expansion. Rehnberg was chairman of the new company, and Landau president. Five subsidiaries were created:

 Halcon Research and Development
 Halcon Scientific Design for design and construction
 Halcon Computer Technologies for computerized engineering services
 Catalyst Development Corp. for manufacture of proprietary catalysts
 Halcon Chemical Company.

Adétikopé Solar Power Station. The Adétikopé Solar Power Station is a planned  solar power plant in Togo, with , attached battery energy storage. The power station is in the development stage, under concessional terms by the company Arise Integrated Industrial Platforms (Arise IIP), a subsidiary of the Africa Finance Corporation (AFC), in partnership with the Government of Togo. As of July 2021 a qualified EPC company was being sought to construct the power station, either on its own or in partnership with the existing stakeholders. When completed, this power station will be the largest grid-ready solar power plant in West Africa. The energy is primarily intended to power an industrial park, Adétikopé Industrial Platform (PIA), a  business and industrial development, immediately north of Lomé, the national capital.

Location
The power station would be located in the Adétikopé Industrial Platform, in Zio Prefecture, in the Maritime Region of Togo. This is approximately , north of the city center of Lomé, Togo's capital city.

Overview
Arise IIP, working with the Togolese government is in the process of establishing an industrial park at Adétikopé. To supply power to the businesses and industries in the new industrial park, Adétikopé Solar Power Station is being developed. In addition to the 390 megawatt solar farm, a battery storage system with capacity of 200MWh and a 161 kVA substation will be constructed.

Tendering for EPC partner
The developer/owners of this power station have given prospective EPC bidders two choices. The first option is to design, build, operate for 5 years and then transfer the power plant to Arise IIP. Under this option, Arise IIP will finance the development. The second option is for the EPC company to form a joint venture with Arise IIP and sign a 20-year power purchase agreement with the Togolese electricity utility company. Under this option Arise IIP and the EPC company will raise the funding jointly.
