SI derived unit

SI derived units are units of measurement derived from the seven base units specified by the International System of Units. They are either dimensionless or can be expressed as a product of one or more of the base units scaled by an appropriate power of exponentiation; the SI has special names for 22 of these derived units, but the rest reflect their derivation: for example, the square metre, the SI derived unit of area. The names of SI derived. However, the symbols for units named after persons are written with an uppercase initial letter. For example, the symbol for hertz is "Hz", but the symbol for metre is "m"; the International System of Units assigns special names to 22 derived units, which includes two dimensionless derived units, the radian and the steradian. Some other units such as the hour, tonne and electronvolt are not SI units, but are used in conjunction with SI units; until 1995, the SI classified the radian and the steradian as supplementary units, but this designation was abandoned and the units were grouped as derived units.

Kevin Jonathan Dallman is a former Canadian-Kazakhstani professional ice hockey defenceman. He most played for Barys Astana of the Kontinental Hockey League; as a youth, Dallman played in the 1995 Quebec International Pee-Wee Hockey Tournament with a minor ice hockey team from Niagara Falls, Ontario. Undrafted, Dallman signed his first professional contract with the Boston Bruins on July 18, 2002 after a successful junior career with Guelph Storm of the Ontario Hockey League. After spending three years with Boston's AHL affiliate the Providence Bruins, Dallman made his debut for the Bruins in the 2005–06 season. Dallman played 21 games for the Bruins before he was claimed off waivers by the St. Louis Blues on December 5, 2005. After a solid performance with the Blues, Dallman signed as a free agent for the Los Angeles Kings to a two-year contract on July 10, 2006. After two years in the Kings organization Dallman left for Europe, signing with Barys Astana of the newly formed Kontinental Hockey League on July 24, 2008.

He became an offensive leader with Barys Astana, leading the KHL in scoring among defenseman with 28 goals and 30 assists for 58 points in 53 games. Dallman joined the national team, his first IIHF tournament for Kazakhstan was the final Olympic qualifying tournament in Riga. On May 18, 2012 Barys Astana team managers refused to extend Dallman's contract. "We have agreed with his agent that if the team fulfills its task and reaches the final of the tournament, we will return to discussing the contract's extension. However the team did not reach the final and Dallman did not show his best skills in the playoffs; the issue in question was. Dallman asked for a four-year extension with significant compensation demands; that is why the decision was made not to extend the contract," Barys president Nurlan Orazbayev said. Dallman signed a two-year contract with SKA Saint Petersburg on May 31, 2012. In May 2014 he returned to Barys Astana. On August 5th 2019, Dallman announced retirement from the KHL after 11 years in the KHL.

His uncle, Marty Dallman, played six games for the Toronto Maple Leafs in the late 1980s and played for Austria at the 1994 Winter Olympics. Biographical information and career statistics from, or, or, or, or The Internet Hockey Database

Gülüstan, Goranboy

Gülüstan is a village in the Goranboy District of Azerbaijan, part of the municipality of Buzluq. Gülüstan is a Persian word and means "The flower Garden". Between the 16th and the 18th century, the Fortress of Gulistan was seat of the Principality of Gulistan under the leadership of the Armenian Melik Beglarian family, one of the Five Melikdoms of Karabakh. Gülüstan has a historical significance for being the village where the Treaty of Gulistan was signed between the Russian Empire and Qajar Iran on 12 October 1813, concluding the nine-year-long Russo-Persian War. According to the agreement, Qajar Iran was forced to recognize Russian rule over territories north of Arax river with the exception of the Khanates of Erivan and Nakhchivan. In the Soviet times, the village was part of the Shahumyan Region, a majority-Armenian administrative unit outside the Nagorno-Karabakh Autonomous Oblast. Before 1991, the village was inhabited by ethnic Armenians who fled in the wake of Operation Goranboy; the Shahumian Region was incorporated into the Goranboy District.

Gülüstan is located in close proximity to the contact line between the Nagorno-Karabakh Defense Army and the army of Azerbaijan. On 3 March 1992 an Armenian transport helicopter Mi-26 carrying around 50 women and children from Gülüstan on board was shot down with a MANPADS rocket from Azerbaijan-controlled territory, 16 people were killed. Notable natives of the village are Shahen Meghrian. Treaty of Turkmenchay Gülüstan, Goranboy at GEOnet Names Server

Badhwar Park

Badhwar Park is the residential complex of the Indian Central Railway and Western Railway officers. It is located at Wodehouse Road in Cuffe Parade; the colony is situated along the coastline. The complex has been aptly named after Shri Fateh Chand Badhwar, the first Indian chairman of the Indian Railway Board. In the past, after its inception in 1925, all chairmen of the Railway Board had been Britons; the beautiful, lush green complex has a club with library etc.. The club has coaching facilities for martial arts. Badhwar Park can be reached from Churchgate or Chhatrapati Shivaji Terminus railway station by catching bus no 138 starting from CST. During the British Raj in India, Colaba railway station was a terminus railway station. At one point in time and Victoria Terminus were not the southern-most endpoint for the Mumbai suburban railway lines, Colaba railway station was terminus of Western Railway line of Mumbai suburban railway; this station was rebuilt as Badhwar Park residential complex.

Badhwar Park was the location of landing of the 10 terrorists from Pakistan on the evening of 26/11/2008, who went on to kill 188 persons in Mumbai

The Disposable American

The Disposable American: Layoffs and Their Consequences is a 2006 book written by New York Times reporter Louis Uchitelle, it was his first. It was published by Inc.. The book is concerned with the far reaching layoffs occurring in the United States, the damage he perceives this causes the country, the psychological harm he perceives dealt to workers by this phenomenon. According to the book's author, Louis Uchitelle, the waves of major layoffs are injurious to the United States in three key areas: the phenomenon disadvantages companies leaving them unable to compete, it has removed numerous middle class jobs, it disadvantages former middle class workers who are forced to work lower paying jobs.

Planetary Data System

The Planetary Data System is a distributed data system that NASA uses to archive data collected by Solar System missions. The PDS is an active archive that makes available well documented, peer reviewed planetary data to the research community; the data comes from orbital and robotic missions and ground-based support data associated with those missions. It is managed by NASA Headquarters' Planetary Sciences Division; the main objective of the PDS is to maintain a planetary data archive that will withstand the test of time such that future generations of scientists can access and use preexisting planetary data. The PDS tries to ensure compatibility of the archive by adhering to strict standards of storage media, archiving formats, required documentation. One critical component of the PDS archive is the storage media; the data must be stored and efficiently with no degradation of the data over the archive's lifespan. Therefore, the physical media must remain readable over many years. PDS is migrating toward electronic storage as its "standard" media.

The format of the data is important. In general, non-proprietary formats are best; when a proprietary format is submitted to the archive an accompanying plain text file is required. It is assumed that the scientists of the future will at least be able to make sense of regular ASCII bytes if the proprietary software and support ceases to exist. PDS allows illustrations to be included in the archive as individual images. PDS adheres to many other standards including, but not limited to, special directory and file naming conventions and label requirements; each file in the PDS archive is accompanied by a searchable label. The archive must be able to stand alone. There is no guarantee that the people who worked with and submitted the data to the archive will be available in the future to field questions regarding the data, its calibration or the mission. Therefore, the archive must include good descriptive documentation of how the spacecraft and its instruments worked, how the data were collected and calibrated, what the data mean.

The quality of the documentation is examined during a mission independent PDS peer review. The PDS is composed of 6 science discipline nodes and 2 support nodes. In addition, there are several subnodes and data nodes. Atmospheres Node – handles non-imaging atmospheric data Geosciences Node – handles data of the surfaces and interiors of terrestrial planetary bodies Cartography and Imaging Science Node – archives many of the larger planetary image data collections Planetary Plasma Interaction Node – handles data consisting of the interaction between the solar wind and planetary winds with planetary magnetospheres and surfaces Ring-Moon Systems Node – handles planetary ring system data Small Bodies Node – handles asteroid and planetary dust data Comet Subnode Asteroid/Interplanetary Dust Subnode Engineering Node – provides systems engineering support to the PDS Navigation and Ancillary Information Facility Node – maintains the SPICE information system The PDS is divided into a number of science discipline "nodes" which are individually curated by planetary scientists.

The PDS Management Council serves as the Technical Policy Board of the PDS, provides findings for NASA with respect to planetary science data management, ensures coordination among the nodes, guarantees responsiveness to customer needs, monitors the appropriate uses of evolving information technologies that may make PDS tasks both more efficient and more cost effective. It is formed by the principal investigators of the science discipline nodes, along with the leaders of the Technical Support Nodes, the Project Manager, Deputy Project Manager; the Solar System Exploration Data Services Office at the Goddard Space Flight Center handles PDS Project Management. NASA and the PDS engaged in development of a Roadmap for the period 2017 to 2026; the purpose of the roadmap effort was to outline a strategy for moving forward in planetary data archiving under the auspices of a growing data volume, new computing capabilities and facilities, a growing community of planetary science investigators.
