Resolution (mass spectrometry)

In mass spectrometry, resolution measures of the ability to distinguish two peaks of slightly different mass-to-charge ratios ΔM, in a mass spectrum.

Resolution and resolving power

There are two different definitions of resolution and resolving power in mass spectrometry.

IUPAC definition

The IUPAC definition for resolution in mass spectrometry is

Where a larger resolution indicates a better separation of peaks. This definition is used in a number of mass spectrometry texts. This use is also implied by the term "high-resolution mass spectrometry."

A high value for resolution corresponding to good separation of peaks is similar to the convention used with chromatography separations, although it is important to note that the definitions are not the same. High resolution indicating better peak separation is also used in ion mobility spectrometry

Resolving power definition

Some mass spectrometrists use the definition that is similar to definitions used in some other fields of physics and chemistry. In this case, resolving power is defined as:

Angular resolution

Angular resolution or spatial resolution describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution.

Definition of terms

Resolving power is the ability of an imaging device to separate (i.e., to see as distinct) points of an object that are located at a small angular distance or it is the power of an optical instrument to separate far away objects, that are close together, into individual images. The term resolution or minimum resolvable distance is the minimum distance between distinguishable objects in an image, although the term is loosely used by many users of microscopes and telescopes to describe resolving power. In scientific analysis, in general, the term "resolution" is used to describe the precision with which any instrument measures and records (in an image or spectrum) any variable in the specimen or sample under study.

HMNZS Resolution (A14)

HMNZS Resolution (A14) was a hydrographic ship of the Royal New Zealand Navy (RNZN). Originally the United States Naval Ship USNS Tenacious (T-AGOS-17), the Stalwart-class ocean surveillance ship was used by the United States to locate and track Soviet submarines from 1989 to 1997, when she was transferred to the RNZN for use as a hydrographic survey ship. She served until 27 April 2012. She was subsequently sold to EGS Group, a private surveying company, and renamed RV Geo Resolution.

Construction

The ship's construction contract was awarded 20 February 1987 to VT Halter Marine, Inc. of Moss Point, Mississippi, under then name Intrepid. Her keel was laid down 26 February 1988, she was launched 17 February 1989 and commissioned as USNS Tenacious on 29 September 1989. The renaming was prompted by protests from veterans of the Essex-class aircraft carrier USS Intrepid, who felt that the surveillance ship was not a fitting vessel to carry on the carrier's name.

Operational history

EMI

EMI Group Limited (originally Electric and Musical Industries), also known as EMI Music or simply EMI, was a British multinational music recording and publishing company, and electronics device and systems manufacturing company, headquartered in London, England.

At the time of its break-up in 2012 it was the fourth-largest business group and family of record labels in the recording industry and was one of the big four record companies (now the big three). Its record labels included EMI Records, Parlophone, Virgin Records, and Capitol Records. EMI Group also had a major publishing arm, EMI Music Publishing—also based in London with offices globally.

The company was once a constituent of the FTSE 100 Index, but faced financial troubles and $4 billion in debt, leading to its acquisition by Citigroup in February 2011. Citigroup's ownership was temporary, as it announced in November 2011 that it would sell its music arm to Vivendi's Universal Music Group for $1.9 billion, and EMI's publishing business to a Sony/ATV consortium for around $2.2 billion. Other members of the Sony consortium include the Estate of Michael Jackson, Blackstone, and Abu Dhabi–owned investment fund Mubadala.

PolyEast Records

PolyEast Records (formerly EMI Philippines) is a record label in the Philippines. It is a member of the Philippine Association of the Record Industry and from 2008 until 2013, the international licensee of EMI.

History

It was inaugurated in 1977 as Canary Records by Orly Ilacad after resigning from Vicor Music due to a major conflict with then co-owner Vic Del Rosario. It became OctoArts International in 1978. It was the first record company that introduced Minus One in the market.

The label's prior international releases were distributed by Dyna Records under the name Dyna EMI until 1995, when it began a distribution deal with EMI & became OctoArts EMI. In 2002, after a series of restructure, it became EMI Philippines.

In 1997 Octoarts was also at its top peak when it introduced its top female pioneering artist Jessa Zaragoza, for her first album entitled "Just Can't Help Feelin" her famous single rose her to popularity distributing the song "Bakit Pa" and also released a film with the same title two years later with Octoarts Films and GMA Films which also led Jessa to finish her last final albums with Octoarts "Phenomenal" (1999) and "Siya Ba Ang Dahilan" (Is She The Reason?) (2000) and also released a compilation entitled The Best Of Jessa Zaragoza before she moved to top pioneering Filipino recording company Star Records.

The First 48

The First 48 is an American documentary television series on A&E. Filmed in various cities in the United States, the series offers an insider's look at the real-life world of homicide investigators. While the series often follows the investigations to their end, it usually focuses on their first 48 hours, hence the title. Each episode picks one or more homicides in different cities, covering each alternately, showing how detectives use forensic evidence, witness interviews and other advanced detective skills to identify suspects. While most cases are solved within the first 48 hours, some go on days, weeks, months, or even years after the first 48.

The series was nominated for a Distinguished Documentary Achievement Award in the Continuing Series category by the International Documentary Association, eventually losing out to American Experience. By season 6, The First 48 had become the highest rated non-fiction justice series on television, and had gained critical acclaim along with controversy. The season 8 premiere, "Gone", which aired on January 1, 2009, garnered a domestic audience of 2.3 million viewers which made it the series' most watched episode, at the time.
