Smear Test
Cytopathology (from Greek , ''kytos'', "a hollow"; , ''pathos'', "fate, harm"; and , ''-logia'') is a branch of pathology that studies and diagnoses diseases on the cellular level. The discipline was founded by George Nicolas Papanicolaou in 1928. Cytopathology is generally used on samples of free cells or tissue fragments, in contrast to histopathology, which studies whole tissues. Cytopathology is frequently, less precisely, called "cytology", which means "the study of cells". Cytopathology is commonly used to investigate diseases involving a wide range of body sites, often to aid in the diagnosis of cancer but also in the diagnosis of some infectious diseases and other inflammatory conditions. For example, a common application of cytopathology is the Pap smear, a screening tool used to detect precancerous cervical lesions that may lead to cervical cancer. Cytopathologic tests are sometimes called smear tests because the samples may be smeared across a glass microscope sli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pap Test
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), cervical smear (BE), cervical screening (BE), or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or colon (in both men and women). Abnormal findings are often followed up by more sensitive diagnostic procedures and, if warranted, interventions that aim to prevent progression to cervical cancer. The test was independently invented in the 1920s by Georgios Papanikolaou and Aurel Babeș and named after Papanikolaou. A simplified version of the test was introduced by Anna Marion Hilliard in 1957. A Pap smear is performed by opening the vagina with a speculum and collecting cells at the outer opening of the cervix at the transformation zone (where the outer squamous cervical cells meet the inner glandular endocervical cells), using an Ayre spatula or a cytobrush. A similar method is used to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smear (card Game)
Smear (also known as Schmier) is a North-American trick-taking card game of the All Fours group, and a variant of Pitch (Setback). Several slightly different versions are played in Michigan, Minnesota, Northern and Central Iowa, Wisconsin and also in Ontario, Canada. It is highly likely that the name is related to the German word '' schmieren'', which is used in point-trick games such as Skat for the technique of discarding a high-value card on a trick which your partner is winning. The name might perhaps be connected to the fact that a high-scoring card may be discarded in a trick won by the player's partner, like in Pinochle, or even to "smudge," which is the highest bid in some forms of Pitch. Ten-point partnership Smear Partnership Smear is played by four players in fixed partnerships, sitting crosswise. It can also be played by six players in three partnerships. The following version is one of several described by John McLeod. Deck and basic game structure The game is p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smear Campaign
A smear campaign, also referred to as a smear tactic or simply a smear, is an effort to damage or call into question someone's reputation, by propounding negative propaganda. It makes use of discrediting tactics. It can be applied to individuals or groups. Common targets are public officials, politicians, political candidates, activists and ex-spouses. The term also applies in other contexts such as the workplace.Jay C. Thomas, Michel Hersen (2002) Handbook of Mental Health in the Workplace The term ''smear campaign'' became popular around 1936. Definition A smear campaign is an intentional, premeditated effort to undermine an individual's or group's reputation, credibility, and character. Like negative campaigning, most often smear campaigns target government officials, politicians, political candidates, and other public figures. However, private persons or groups may also become targets of smear campaigns perpetrated in companies, institutions, the legal system, and other ...

Smear Campaign (album)
''Smear Campaign'' is the twelfth studio album by grindcore band Napalm Death. It was recorded with producer Russ Russell at Foel Studios, Wales, and was released on 15 September 2006. It was released as a regular CD, and as a digipak edition featuring two bonus tracks and a sticker of the cover artwork. Differently coloured versions of the cover art exist. Shortly before the release, Barney Greenway mentioned that the album features a guest appearance by Anneke van Giersbergen, ex-vocalist for the Dutch rock band The Gathering, saying, " hehas offered up a few parts to a track, which I've yet to hear. But before some people recoil in horror about Napalm going operatic rock or whatever, this was done for good effect and relevance to the track. It will work. It will rock. I'm sure. And we're grateful to Anneke (who is an awesome vocalist in her own right) in advance for giving it a stab." ''Smear Campaign'' is a concept album criticising religion in general. Track listing P ...

Pat Smear
Georg Albert Ruthenberg (born August 5, 1959), better known by his stage name Pat Smear, is an American musician. He is best known for being the lead guitarist and co-founder of Los Angeles-based punk band The Germs and for being a rhythm guitarist for the rock band Nirvana, which he joined as a touring guitarist in 1993, and Foo Fighters, with whom he has recorded six studio albums. After Nirvana disbanded following the suicide of its frontman Kurt Cobain, drummer Dave Grohl went on to become the frontman of rock band Foo Fighters, with Pat soon joining on guitar. He left Foo Fighters in 1997, before rejoining as a touring guitarist in 2005, and has been a full-time member since 2010. Early life Georg Ruthenberg was born and raised in West Los Angeles, California to a mother of African-American and Native American descent and a Jewish German immigrant father. His parents enrolled him in piano lessons at a young age, and a few years later, he began teaching himself to play the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smear (optics)
In optics, smear is used to refer to motion that has low temporal frequency relative to the integration/exposure time. This typically results from a relative rate of the image with respect to the detector (e.g., caused by movement in the scene). Smear is typically differentiated from jitter, which has a higher frequency relative to the integration time. Whereas smear refers to a relatively constant rate during the integration/exposure time, jitter refers to a relatively sinusoidal motion during the integration/exposure time. The equation for the optical modulation transfer function associated with smear is the standard sinc In mathematics, physics and engineering, the sinc function, denoted by , has two forms, normalized and unnormalized.. In mathematics, the historical unnormalized sinc function is defined for by \operatornamex = \frac. Alternatively, the u ... function associated with an extended sample :\mathrm_\mathrm(u) = \frac where is the spatial frequency an ...

Glissando
In music, a glissando (; plural: ''glissandi'', abbreviated ''gliss.'') is a glide from one pitch to another (). It is an Italianized musical term derived from the French ''glisser'', "to glide". In some contexts, it is distinguished from the continuous portamento. Some colloquial equivalents are slide, sweep (referring to the "discrete glissando" effects on guitar and harp, respectively), bend, smear, rip (for a loud, violent gliss to the beginning of a note), lip (in jazz terminology, when executed by changing one's embouchure on a wind instrument), plop, or falling hail (a glissando on a harp using the back of the fingernails). On wind instruments, a scoop is a glissando ascending to the onset of a note achieved entirely with the embouchure. Portamento Prescriptive attempts to distinguish the glissando from the portamento by limiting the former to the filling in of discrete intermediate pitches on instruments like the piano, harp, and fretted stringed instruments have run u ...

Astronomical Interferometer
An astronomical interferometer or telescope array is a set of separate telescopes, mirror segments, or radio telescope antenna (radio), antennas that work together as a single telescope to provide higher resolution images of astronomical objects such as stars, nebulas and galaxy, galaxies by means of interferometry. The advantage of this technique is that it can theoretically produce images with the angular resolution of a huge telescope with an aperture equal to the separation between the component telescopes. The main drawback is that it does not collect as much light as the complete instrument's mirror. Thus it is mainly useful for fine resolution of more luminous astronomical objects, such as close binary stars. Another drawback is that the maximum angular size of a detectable emission source is limited by the minimum gap between detectors in the collector array. Interferometry is most widely used in radio astronomy, in which signals from separate radio telescopes are combi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandwidth Smearing
Bandwidth smearing is a chromatic aberration of the reconstructed image of a celestial body observed by an astronomical interferometer that occurs because of the frequency bandwidth. In Fourier terms, the different frequencies of the bandwidth probe different spatial frequencies which results in a reconstruct map containing elongated radial features. It is overcome by going to higher spectral resolutions or, in radioastronomy Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming f ..., by using different centres of phase for image reconstruction.

Time Smearing
Time smearing or time-average smearing is the degradation of the reconstructed image of a celestial body observed by a ground-based interferometer that occurs because of the duration of the observation. Unlike single telescopes or cameras that can compensate the Earth's rotation in real time with a dedicated mount, the different telescopes of the interferometer are at fixed positions on the Earth. As a result, maps obtained with interferometers feature the elongated orthoradial features similar to those of night sky photographs taken with a fixed tripod, unless they use short enough integration times. The smearing is a problem for long integration times or very separated telescopes. Mostly an issue in radioastronomy, it severely limits the usable field of view of observations in very long baseline interferometry Very-long-baseline interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy. In VLBI a signal from an astronomical radio source, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
