Copper(I) sulfate. Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu2SO4. It is a white solid, in contrast to copper(II) sulfate, which is blue in hydrous form. Compared to the commonly available reagent, copper(II) sulfate, copper(I) sulfate is unstable and not readily available.

Structure 
Cu2SO4 crystallizes in the orthorhombic space group Fddd. Each oxygen in a sulfate anion is bridged to another sulfate by a copper atom, and the Cu−O distances are 196 pm.

Synthesis 
Cuprous sulfate is produced by the reaction of copper metal with sulfuric acid at 200 °C:

Cu2SO4 can also be synthesized by the action of dimethyl sulfate on cuprous oxide:

The material is stable in dry air at room temperature but decomposes rapidly in presence of moisture or upon heating. It decomposes into copper(II) sulfate pentahydrate upon contact with water.

Kong Inc.. Kong Inc. is a software company that provides open-source platforms and cloud services for managing, monitoring, and scaling application programming interfaces (APIs) and microservices. Some of the products offered by Kong Inc. include: Kong Gateway, an open-source API gateway; Kong Enterprise, an API platform that is built on top of Kong Gateway; Kong Konnect, a service connectivity platform; Kuma, an open-source service mesh; Kong Mesh, an enterprise-grade service mesh that is built on top of Kuma; and Insomnia, an open-source API design and testing tool.

History 

The original product was first developed in 2009 in Milan, Italy and first incorporated in the US as Mashape, Inc. The original project was a mash-up (web application hybrid) platform used to aggregate different functions and UI elements from third-party products and services. While developing the product the team dealt with a number of APIs, which inspired the founders to create a unified hub to organize the growing market of APIs. In November 2010 Mashape appeared online as an Alpha product  and launched in private Beta in June 2011. The team raised the first funds in the US. In 2010, Mashape received its first angel funding and a further $1,500,000 in seed funding. Mashape then rejected some acquisition offers in 2011.

In 2015 Mashape launched an open source project called Kong, which later helped the company secure an $18 million in Series B funding.  Subsequently, with the intention of pivoting the company's focus to its new Kong business, Mashape sold API Marketplace to RapidAPI, and rebranded the company to Kong Inc.

In 2019, Kong acquired Insomnia, an open-source API testing platform.

Technology 
In 2015, Mashape released Kong, an open-source management layer for APIs and Microservices that is built on top of Nginx and Cassandra/PostgreSQL with the claim of improving performance and reliability. Kong is the main engine of Mashape's marketplace.

Bushcaddy. Bushcaddy Aircraft Canada, usually just called Bushcaddy or BushCaddy, was a Canadian aircraft manufacturer based at the Cornwall Regional Airport in Summerstown, Ontario. The company specialized in the design and manufacture of kit aircraft.

By August 2020 the company website had been blanked and it is likely that the company is no longer in business.

History 

The company started as a flight training operation called Club Aeronautique Delisle Incorporated (CADI), based in Lac Saint-Jean, Quebec. It was founded by Jean Eude Potvin who designed the CADI R-80 and put it into production as a kit aircraft in 1994. He went on to design and build the R-120 and L-160.

Sean Gilmore and Marlene Gill started a flight training venture at Montréal/Saint-Lazare Aerodrome, operating a CADI R-80 aircraft. Impressed with the design they became distributors for Potvin, handling marketing outside of Quebec. In 1998 Potvin expressed a desire to retire and Gilmour and Gill bought CADI, including the rights to the R-80, R-120 and L-160 aircraft designs. They renamed the company Canadian Light Aircraft Sales and Service, commonly called CLASS. Between 1998 and 2001 Potvin still produced parts, as CLASS assumed production. Potvin retired in 2001.

To preserve the CADI name the aircraft line was called BushCaddy, a play on the abbreviation and the meaning of one who carries. To expand production the company moved to larger accommodation at nearby Les Cedres, Quebec. By 2005 they had five employees with Gilmore doing the design and engineering work and Gill handling the marketing and financial aspects. Gilmore designed the Bushcaddy L-162 Max and L-164.

In about 2010 Gilmore and Gill retired and sold the company to Tony Watkin, an Australian who relocated it to Lachute, Quebec and renamed it after the aircraft line itself, Bushcaddy International Inc.

In November 2012 the company moved production to the Cornwall Regional Airport at Summerstown, Ontario and also accepted a contract with the airport to operate the UNICOM radio service.

Description

High availability clusters (HAC) improve application availability by failing them over or switching them over in a group of systems—as opposed to High Performance Clusters, which improve application performance by running them on multiple systems simultaneously. SIOS LifeKeeper provides continuous monitoring of the entire application stack and will recover a service or application locally or on another cluster node at the same site or another geographic location. It supports all major Linux distributions and accommodates a wide range of storage architecture. SIOS clustering software synchronizes local storage on all cluster nodes creating a cluster in a cloud where shared storage is not available. SIOS LifeKeeper is SAP-certified for SAP NetWeaver and SAP S/4HANA to monitor the critical services and automatically apply SAP best practices for nonstop operation of critical SAP environments.

Similar products include Fujitsu PRIMECLUSTER, IBM HACMP, HP ServiceGuard, IBM Tivoli System Automation for Multiplatforms (SA MP), Linux-HA, Microsoft Cluster Server (MSCS), NEC ExpressCluster, Red Hat Cluster Suite, Veritas Cluster Server and Sun Cluster. 

In 2009, the company launched a program enabling users of HP ServiceGuard, which HP stopped selling that year, to migrate to the LifeKeeper for Linux product. LifeKeeper has won the Best Clustering Solution Award at LinuxWorld on several occasions.

George G. Sharp. George G. Sharp, Inc. is a marine design and naval architecture firm established in 1920 in New York City by George Gillies Sharp, former Chief Surveyor of the American Bureau of Shipping. The firm started with the design of excursion steamboats on the Delaware and Hudson rivers, then moved into oceangoing passenger and cargo shipping. From 1934 Sharp designed a standardized series of merchant ships for the U.S. Department of Commerce. During World War II Sharp designed the standardized Victory ship, of which 534 were built, and 50 escort carriers.

Some of the 1500 vessels designed by Sharp include:
 Type C2 ship prototype
 Type C3 ship prototype
 SS Ancon, SS Panama and SS Cristobal, "World of Tomorrow" ships for the Panama Railroad Steamship line, 1939
 Milwaukee Clipper, the last passenger steamship on the Great Lakes, 1940
 Mississippi River Towboat, built for the U.S. Army Corp Engineers, 1942
 Victory ship, 534 built during World War II
 , 50 built during World War II
  and three other destroyer tenders based on C3 hulls during World War II
 , 13 built for the U.S. Coast Guard during World War II
 ,  and  passenger cargo ships for the Mississippi Shipping Company's South American Service, 1946–47
  and  storeships for the U.S. Navy in the 1950s
 , class of seven for the U.S. Navy in the 1960s
 NS Savannah, the first nuclear-powered merchant ship
 , four nuclear-powered cruisers for the U.S. Navy in the 1970s
 Staten Island Ferrys Andrew J. Barberi and Samuel I. Newhouse (1970s), Alice Austen and John A. Noble (1980s and 1990s), and the Guy V. Molinari, Senator John. J. Marchi and Spirit of America (2000s).

By the 1930s Sharp was described together with Gibbs & Cox as one of the leading naval architecture firms in the United States. In 1938, he designed the passenger cargo vessel Cristobal for Panama Line Service to the Canal Zone.

Sharp prepared the working drawings for the Casablanca class escort carriers built by Henry J. Kaiser's California Shipbuilding Corporation in 1942–43. and the working plans for the Victory Ship series in 1943, allowing individual shipbuilding yards to modify the plans according to local practices.

After World War II, the company developed a 17,000-ton luxury liner, the SS Del Norte, for service between New Orleans and the east coast of South America. The Del Norte was built by the Ingalls Shipbuilding Corporation at Pascagoula, Mississippi and each room featured ocean views through casement windows. The ships were characterized by a dummy funnel in which officer's quarters, radio room and emergency generator were housed. Del Norte, first of the three, was described as 'today's ship of tomorrow,' it was the first cargo-passenger ship equipped with commercial radar.

In addition to design services, Sharp provides consultation on modification, maintenance, safety, systems integration and program management, with about 600 employees.

1919 United States Army Air Service aircraft designation system. From 1919 until 1924, the United States Army Air Service used a system to designate the types of aircraft it was operating, based on role and specific characteristics of the aircraft. When first instituted, Roman numerals were used to number the designations in use. These numerals were only applied to the first 15 types before being abandoned. Air-cooled and Water-cooled refer to the engines installed, while Pursuit was the name given to fighter aircraft in the US Army, at that time. The system was replaced by the 1924 United States Army Air Service aircraft designation system.

The vessels are also fitted with various terrestrial and satellite based communication systems including a Fleet-500 satellite communication system.

The ships are equipped with a 30 mm CRN 91 Naval Gun, which is gyro-stabilized with an electro-optical fire control system. They can undertake day and night patrolling for anti-smuggling, anti-poaching and fisheries monitoring in shallow waters. They also carry on board a high-speed fibre-reinforced plastic boat, two Gemini boats and one water scooter for search and rescue operations. They have fully air conditioned and modular accommodation for 6 officers and 34 sailors.

Operational history 
On the evening of 24 August 2024, ICGS Rajratan, in coordination with Maritime Rescue Coordination Sub Centre (MRCSC) Pipavav and an ICG Dornier 228, rescued 9 crew members of IFB Angel. The Fishing Boast was adrift 70 km south of Diu amid rough seas due to an engine failure. The boat was later towed to Jafarabad.

Ships in class
The first vessel in the series ICGS Rajshree was commissioned by Director General Indian Coast Guard, Vice Admiral M.P. Muralidharan at GRSE Jetty on 15 February 2012. Firstly commanded by Commandant Pankaj Verma, an alumnus of the prestigious US Naval War College, Newport. The ship is named after an old Seaward class defense boat (SDB) of the Indian Navy INS Rajshree that served from 1983 to 2006.The second ship, ICGS Rajtarang, was commissioned at Chennai on 19 May 2012, and the third, ICGS Rajkiran, on  29 August 2012, at Visakhapatnam.
