text: The Goldbergs (2013 TV series)

text: Premise[edit]

text: The Goldbergs is set in the 1980s in Jenkintown, Pennsylvania. The show is loosely based on the showrunner's childhood, during which he videotaped events, many of which are reenacted throughout the program. It shows the reality of the '80s through a young boy's eyes.[6]

text: The series stars Jeff Garlin as patriarch Murray and Wendi McLendon-Covey as matriarch Beverly. Their two older children are Erica (Hayley Orrantia) and Barry (Troy Gentile). The youngest child, Adam (Sean Giambrone), documents his family life with his video camera. Beverly's father, Albert "Pops" Solomon (George Segal), is frequently around to provide advice or to help out his grandchildren (often behind his daughter's back).

text: The present-day "Adult Adam" (Patton Oswalt) narrates every episode as taking place in "1980-something".

text: Many references to real-life Philadelphia-area businesses are made, including the Wawa Inc. convenience store chain, Gimbel's department store, Willow Grove Park Mall, and Kremp's Florist of Willow Grove, Pennsylvania.

text:
Wendi McLendon-Covey as Beverly Goldberg (née Solomon),[3] the overprotective matriarch of the Goldbergs. She frequently injects herself into her children's lives, often to their embarrassment, and is supremely confident in their abilities.
Sean Giambrone as Adam Fredrick Goldberg,[3] the pop-culture obsessed youngest child of the Goldbergs. Smart and geeky, he often films his family's activities on a VHS camcorder. He often ends up having to use his middle initial to distinguish himself from another Adam Goldberg who attends the same school and is also an aspiring filmmaker.

Patton Oswalt voices the adult Adam Goldberg,[7] who narrates the show from the present day.

Jeff Garlin as Murray Goldberg,[3] the gruff, somewhat asocial patriarch of the Goldbergs. Unlike Beverly, he is realistic about his children's abilities and believes she smothers them too much. Despite his apathetic tendencies at home, he values hard work and has held various full time positions since his teenage years. Though he does not always show affection for his children, calling them morons when they make mistakes or behave in silly ways, he truly cares about them and wants them to learn how to fend for themselves. He runs his father-in-law's furniture business, loves sports, and is often seen lounging in front of his TV in his white briefs.
Troy Gentile as Barry Norman Goldberg,[3] the overconfident, slightly dim-witted middle child of the Goldbergs. Though seemingly untalented in every way (except in ice hockey and wrestling, at which he excels), he remains highly self-assured while trying to become popular in high school. He is determined to dominate everything he does, including sports; loves rap music; and is the leader of a crew called the Jenkintown Posse (abbreviated JTP, which fellow members repeat whenever the initials are spoken).
Hayley Orrantia as Erica Dorothy Goldberg,[3] the somewhat bad-tempered oldest child of the Goldbergs. Smart and musically gifted but rebellious, she is popular in school and dominant over her younger brothers. As of the fifth season, Erica has left for college at DC. School of the Arts. "Erica" is based on Adam's real-life brother, Eric Goldberg.[8]
George Segal as Albert "Pops" Solomon,[3] Beverly's laid-back widower father. Though an elderly man with a number of comic eccentricities, he acts much younger than his age and often gives sage advice to his grandchildren. Adam considers him his best friend. He once owned a successful furniture store called Ottoman Empire that allowed him to retire comfortably, and he now lets his son-in-law Murray run the business.
AJ Michalka as Lainey Lewis (Season 3–4; recurring 1–2, 5-present),[9] Erica's best friend and one of the most popular girls at school, whom Barry has had a lifelong crush on. To the surprise of many, Lainey kisses Barry at a party in the first-season finale, the two slowly grow closer together in season two, and eventually become an unlikely couple. Following the fourth season, she has gone to attend fashion school in Savannah, Georgia and ended her relationship with Barry. In season 5, she returns to Jenkintown after dropping out along with Erica to start a band. In the final seconds of the season finale she and Barry agree to wed.
Sam Lerner as 'Madman' Geoff Schwartz (Season 5-present; recurring 2-4),[10] one of Barry's best friends. The nickname "Madman" is a form of ironic humor, given how well-behaved the character is, especially compared to Barry. He is infatuated with Erica and makes many futile attempts to win her affections. At the end of the third season, he begins dating Evelyn Silver just as Erica realizes she reciprocates Geoff's feelings. He later breaks up with Evey to be with Erica.

text: Production[edit]

text: Casting[edit]

text: The project originally received a script commitment from Fox in August 2011. After Adam Goldberg's previous show, Breaking In, was canceled, he did not want to wait for another pilot season to arrive and moved it to ABC, who agreed to immediately produce it.[19][20] On January 11, 2013, Wendi McLendon-Covey was cast as the pilot's lead;[21] later, Jeff Garlin and George Segal joined the cast.[22][23]

text: Filming[edit]

text: The pilot episode was directed by Seth Gordon. On May 10, 2013, ABC picked up the show to series to air in the 2013–14 American television season.[24] It was later picked up for a full season order on November 1, 2013.[25] The program is filmed on a series of stages at Sony Pictures Studios.

text: Music[edit]

text: The show's theme song, "Rewind," was written at Goldberg's request by I Fight Dragons, his favorite band, specifically for the show.[26] A soundtrack, featuring songs performed on the show by the cast members, was released on December 6, 2017.[27]

text: Reception[edit]

text: Critical reception[edit]

text: The Goldbergs pilot received mixed reviews, averaging a score of 52% on Metacritic based on reviews from 26 critics.[28]

text: Tim Goodman of The Hollywood Reporter called it "one of the rare freshman comedies to deliver", giving credit to the show's "outstanding writing" and "strong cast".[29] David Wiegand of the San Francisco Chronicle wrote, "you'll immediately like everyone in the family and the jokes derive from credible situations".[30]

text: Hank Stuever of The Washington Post said the show was "obnoxiously loud".[31] David Hinckley of The New York Daily News said the show is "just awful".[32] Tierney Bricker of E! News gave a more positive review, saying that the show is "like Modern Family mixed with A Christmas Story".[33]

text: The Goldbergs was included in TV Guide's 2013 Top Twenty "Best Shows of the Year",[34] along with The Hollywood Reporter[35] and Today.[36] In addition, SpoilerTV awarded The Goldbergs with the honor of Best Comedy of 2013–2014.[37]

text: The second season had a Rotten Tomatoes score of 100% fresh with five reviews,[38] and there were many calls from both critics and the public to renew the show for a third season.[citation needed] The show continued to be well received, with Entertainment Weekly calling the season two premiere "the best of any family comedy on TV in the way it eschews dysfunction for its more appropriate, real-world term: love".[39]

text: After the series was renewed for season 3, ABC network chief Paul Lee stated that both he and ABC believed that the show will be around for "a long time".[40]

text: Syndication[edit]

text: The show went into syndication in September 2017 and began airing on local stations on September 11, Nick at Nite on September 18, Pop on September 24, and will also begin to air on TV Land.

text: Schooled[edit]

text: In November 2016, it was first reported that ABC was developing a spinoff that would centre around recurring character Rick Mellor, played by Bryan Callen.[57] On January 10, 2017, Wendi McClendon-Covey's character was reported as appearing in the script in a guest appearance.[58] The script was ordered to pilot on February 2, 2017.[59].

text: On March 16, 2017, it was confirmed that Nia Long had been cast as the female lead in the role of Lucy Winston. At the same time it was confirmed that Tim Meadows would reprise his recurring role from The Goldbergs as Andre Glascott. Jay Chandrasekhar was also confirmed to direct.[60]

text: On May 17, 2017, ABC passed on the spin-off,[61] despite it reportedly testing very well - going as far to test better than the pilot of the original series.[62] At the same time, Adam F. Goldberg revealed the title of the failed spin-off - "Schooled".[63]

text: On January 8, 2018, it was announced that the pilot would air as a special episode of The Goldbergs on January 24, 2018, under the episode title The Goldbergs: 1990-Something. Along with Nia Long as Lucy Winston and Tim Meadows as teacher-turned-principal Andre Glascott (who is also revealed to be Lucy's brother), the pilot also starred Rachel Crow as Lucy's rebellious teenage daughter Felicia, and Summer Parker as Felicia's bubbly younger sister Gigi, with Octavia Spencer narrating as the present-day Felicia.

text: After the pilot aired, Goldberg had expressed hope that the airing would prompt discussions with ABC that could lead to the series being picked up for the 2018–19 TV season.[62] Three months later, on April 16, 2018, it was announced that ABC had officially picked up the spinoff, Schooled, for a 13-episode season slated to air in 2018. It was also announced that AJ Michalka would reprise her role as Lainey Lewis from The Goldbergs in the new show, but Nia Long will not return to the spinoff due to being a regular cast member on the CBS drama series NCIS: Los Angeles.[64]


document_title: Heart murmur

question_text: where does the murmur associated with aortic stenosis radiate

root

text: Heart murmur

text: Classification[edit]

text: Murmurs can be classified by seven different characteristics: timing, shape, location, radiation, intensity, pitch and quality.[3]

tag: p

text:
Timing refers to whether the murmur is a systolic or diastolic murmur.
Shape refers to the intensity over time; murmurs can be crescendo, decrescendo or crescendo-decrescendo. Crescendo murmurs progressively increase in intensity. Decrescendo murmurs progressively decrease in intensity. With crescendo—decrescendo murmurs (diamond or kite-shaped murmurs), a progressive increase in intensity is followed by a progressive decrease in intensity.
Location refers to where the heart murmur is usually heard best. There are four places on the anterior chest wall to listen for heart murmurs; each of the locations roughly corresponds to a specific part of the heart and should be listened to (through the stethoscope) with the patient lying down, face up. The four locations are:

Aortic region - the 2nd right intercostal space.
Pulmonic region - the 2nd left intercostal spaces.
Tricuspid region - the 4th left intercostal space.
Mitral region - the 5th left mid-clavicular intercostal space.

tag: ul

text:
Left lateral decubitus.
With the patient sitting upright.
With the patient leaning forward and exhaling.

text:
Radiation refers to where the sound of the murmur radiates. The rule of thumb is that the sound radiates in the direction of the blood flow.
Intensity refers to the loudness of the murmur, and is graded according to the Levine scale, from 1 to 6:[4][5]

The murmur is only audible on listening carefully for some time.
The murmur is faint but immediately audible on placing the stethoscope on the chest.
A loud murmur readily audible but with no palpable thrill.[6]
A loud murmur with a palpable thrill.
A loud murmur with a palpable thrill. The murmur is so loud that it is audible with only the rim of the stethoscope touching the chest.
A loud murmur with a palpable thrill. The murmur is audible with the stethoscope not touching the chest but lifted just off it.

Pitch may be low, medium or high and is determined by whether it can be auscultated best with the bell or diaphragm of a stethoscope.
Quality refers to unusual characteristics of a murmur, such as blowing, harsh, rumbling or musical.

text: A mnemonic to remember what characteristics to look for when listening to murmurs is SCRIPT: Site, Configuration (shape), Radiation, Intensity, Pitch and quality, and Timing in the cardiac cycle.

text: The use of two simple mnemonics may help differentiate systolic and diastolic murmurs; PASS and PAID. Pulmonary and aortic stenoses are systolic while pulmonary and aortic insufficiency (regurgitation) are diastolic. Mitral and tricuspid defects are opposite.[7]

text: Interventions that change murmur sounds[edit]

text:
Inhalation leads to an increase in intrathoracic negative pressure, which increases the capacity of pulmonary circulation, thereby prolonging ejection time. This will affect the closure of the pulmonary valve. This finding, also called Carvallo's maneuver, has been found by studies to have a sensitivity of 100% and a specificity of 80% to 88% in detecting murmurs originating in the right heart.[8][9] specifically positive Carvallo's sign describes the increase in intensity of a tricuspid regurgitation murmur with inspiration.[10]
Abrupt standing
Squatting, by increasing afterload and increasing preload.
Handgrip maneuver, by increasing afterload
Valsalva maneuver. One study found the Valsalva maneuver to have a sensitivity of 65%, specificity of 96% in detecting hypertrophic obstructive cardiomyopathy (HOCM).[8] Both standing and Valsalva maneuver will decrease venous return and subsequently decrease left ventricular filling, resulting in an increase in the loudness of the murmur of hypertrophic cardiomyopathy, since outflow obstruction is increased by decreasing preload. Alternatively, squatting increases systemic vascular resistance, increasing afterload and helping to hold the obstruction in a more open configuration, decreasing the murmur. Maximum handgrip exercise also results in a decrease in the loudness of the murmur.[11]
Post ectopic potentiation
Inhaled amyl nitrite is a vasodilator that diminishes systolic murmurs in left-to-right shunts in ventricular septal defects, and reveals right-to left shunts in the setting of a pulmonic stenosis and a ventricular septal defect.[12]
Methoxamine
Positioning of the patient. That is, putting patients in the left lateral position will allow a murmur in the mitral valve area to be more pronounced.

text: Anatomic sources[edit]

text: Systolic

text: Aortic valve stenosis typically is a crescendo/decrescendo systolic murmur best heard at the right upper sternal border sometimes with radiation to the carotid arteries. In mild aortic stenosis, the crescendo-decrescendo is early peaking whereas in severe aortic stenosis, the crescendo is late-peaking, and the S2 heart sound may be obliterated.

text: Stenosis of Bicuspid aortic valve is similar to the aortic valve stenosis heart murmur, but a systolic ejection click may be heard after S1 in calcified bicuspid aortic valves. Symptoms tend to present between 40 and 70 years of age.

text: Mitral regurgitation typically is a holosystolic (pansystolic) murmur heard best at the apex, and may radiate to the axilla or precordium. A systolic click may be heard if there is associated mitral valve prolapse. Valsalva maneuver in mitral regurgitation associated with mitral valve prolapse will decrease left ventricular preload and move the murmur onset closer to S1, and isometric handgrip, which increases left ventricular afterload, will increase murmur intensity. In acute severe mitral regurgitation, a holosystolic (pansystolic) murmur may not be heard.

text: Pulmonary valve stenosis typically is a crescendo-decrescendo murmur heard best at the left upper sternal border, associated with a systolic ejection click that increases with inspiration (due to increased venous return to the right side of the heart) and sometimes radiates to the left clavicle.

text: Tricuspid valve regurgitation presents as a holosystolic (pansystolic) murmur at the left lower sternal border with radiation to the left upper sternal border. Prominent v and c waves may be seen in the JVP (jugular venous pressure). The murmur will increase with inspiration.

text: Hypertrophic obstructive cardiomyopathy (or hypertrophic subaortic stenosis) will be a systolic crescendo-decrescendo murmur best heard at the left lower sternal border. Valsalva maneuver will increase the intensity of the murmur, as will changing positions from squatting to standing.

text: Atrial septal defect will present with a systolic crescendo-decrescendo murmur best heard at the left upper sternal border due to increased volume going through the pulmonary valve, and is associated with a fixed, split S2 and a right ventricular heave.

text: Ventricular septal defect (VSD) will present as a holosystolic (pansystolic) murmur at the left lower sternal border, associated with a palpable thrill, and increases with isometric handgrip. A right to left shunt (Eisenmenger syndrome) may develop with uncorrected VSDs due to worsening pulmonary hypertension, which will increase the murmur intensity and be associated with cyanosis.

text: Flow murmur may be heard at the right upper sternal border in certain conditions, such as anemia, hyperthyroidism, fever, and pregnancy.

text: Diastolic

text: Aortic valve regurgitation will present as a diastolic decrescendo murmur heard at the left lower sternal border or right lower sternal border (when associated with a dilated aorta). This may be associated with bounding carotid and peripheral pulses (Corrigan's pulse, Watson's water hammer pulse), and a widened pulse pressure.

text: Mitral stenosis typically presents as a diastolic low-pitched decrescendo murmur best heard at the cardiac apex in the left lateral decubitus position. It may be associated with an opening snap. Increasing severity will shorten the time between S2(A2) and the opening snap. (i.e. In severe MS the opening snap will occur earlier after A2)

text: Tricuspid valve stenosis presents as a diastolic decrescendo murmur at the left lower sternal border, and signs of right heart failure may be seen on exam.

text: Pulmonary valve regurgitation presents as a diastolic decrescendo murmur at the left lower sternal border. A palpable S2 in the second left intercostal space correlates with pulmonary hypertension due to mitral stenosis.

text: Continuous and Combined Systolic/Diastolic

text: Patent ductus arteriosus may present as a continuous murmur radiating to the back.

text: Severe coarctation of the aorta can present with a continuous murmur: a systolic component at the left infraclavicular region and the back due to the stenosis, and a diastolic component over the chest wall due to blood flow through collateral vessels.

text: Acute severe aortic regurgitation is associated with a three phase murmur, specifically a midsystolic murmur followed by S2, followed by a parasternal early diastolic and mid-diastolic murmur (Austin Flint murmur). Although the exact cause of an Austin Flint murmur is unknown, it is hypothesized that the mechanism of murmur is from the severe aortic regurgitation jet vibrating the anterior mitral valve leaflet, colliding with the mitral inflow during diastole, with increased mitral inflow velocity from the narrowed mitral valve orifice leading to the jet impinging on the myocardial wall.[13][14]

text: Another uncommon cause of a continuous murmur is a ruptured sinus of valsalva.[15] Usually the murmur is well heard in the aortic area and along the left sternal border.

text: Types and disease associations[edit]

text: Cooing dove murmur[edit]

text: The cooing dove murmur is a cardiac murmur with a musical quality (high pitched - hence the name) and is associated with aortic valve regurgitation (or mitral regurgitation before rupture of chordae). It is a diastolic murmur which can be heard over the mid-precordium.[1]

tag: table

text: Alex (Jeff Roop) and Jenn (Missy Peregrym) are shown driving from the city towards the country in their SUV. Jenn uses her cell phone, which irritates Alex. They arrive at the visitor center and are greeted by the park ranger (Nicholas Campbell). Alex tells him they have a reservation and will be leaving Monday. Alex also claims he is experienced and does not need a trail map, so the pair leave without one. As the couple prepares for their backpacking trip, Alex sees that Jenn has packed her cellphone on the left side pocket of her backpack.

text: The duo arrive at their campsite by canoe. As they unload and set up their tent, Alex pokes fun at Jenn's handheld flare and bear spray, claiming she won't need it. The two skinny dip at a waterhole. As night begins to settle, Alex goes for more firewood, leaving Jenn alone. He comes back to find that Brad (Eric Balfour) has approached Jenn whilst he was gone. Alex sees the duo and loudly drops the firewood to interrupt their conversation. He finds out that Jenn has invited Brad for dinner, as Brad has caught a few fish. Alex goes into the tent to look for a shirt and calls Jenn inside to talk with her about Brad.

text: When the couple come out of the tent, Brad sees that he is unwanted and decides to leave. The couple state it was a misunderstanding, and Brad is invited to dinner. Throughout dinner, Alex and Jenn are uneasy. When asked if they should pair the fish with a starch, Alex picks veggies and Brad picks potatoes. When Jenn offers to have both, Brad insists on having only potatoes, further increasing the tension. Brad is very comfortable in front of the couple to the point of urinating in front of them, but the couple become more and more uneasy.

text: The dinner concludes and as Brad departs for his own trek, he turns around and confronts Alex face-to-face about his statement on having a "misunderstanding". Alex eventually explains himself and Brad walks away. Alex reprimands Jenn for asking a stranger to dinner, as she apologizes multiple times.

text: Alex makes breakfast for Jenn the next morning, which is the first time he has done so for her. The couple continue to hike. Alex notices a bear print in the trail but keeps it to himself and continues on the trail. He sees a wintergreen plant and eats the leaves, while Jenn declines. As night settles again, the duo set up camp. Throughout the night, strange noises are heard, scaring Jenn. Alex dismisses the noises as acorns falling. In the morning, Alex stands outside looking at a broken branch. Jenn says with sarcasm "Did an acorn do that?".

text: The couple continue their hike and Alex decides to go off the path to the lake he has mentioned and been to before. Just as he thinks they are about to be greeted by a beautiful view of the lake, he is shocked to find out they are in the middle of a forest. The two realize they are lost and without a trail map. Alex also reveals that he secretly left Jenn's cellphone in the car. The two get into a heated argument, with Jenn berating Alex for trying to impress her and pointlessly wandering off the trail. Jenn asks why Alex even brought the two on the trip, and he reveals he was going to propose.

text: At night, a black bear pokes around the tent while the two sleep and eats the food stored in a bag outside. The couple find the torn cans in the morning, and Alex tells her it must have been a raccoon he saw last night. They hike almost an entire day, trying to find their way out, and stumble across signs of a bear. They try to hike as far as possible before dark, and then camp for the night. The bear attacks the following morning, making its way into the tent and lashing Jenn's arm before biting into Alex's shin. It retreats momentarily from Jenn's bear mace before dragging Alex outside and eating him alive. Jenn escapes the battered tent while the bear is occupied with Alex, taking the engagement ring before running away.

text: She sees some wintergreen and begins eating the leaves by the bunch, and then breaks her leg while descending a waterfall when again being chased by the bear. She begins succumbing to dehydration, but manages to make her way back to the canoe by trailing a buck. She manages to paddle back to the visitor center. Brad is seen about to embark with a group of tourists when one of them points to Jenn, who had just collapsed on the ground, and Brad rushes to her aid.

text: Historical trend[edit]

text:
Taking the above data and plotting it yields the graph shown to the right.
The dark plot is the nominal issued price of the stamp and the light plot is the price adjusted for inflation and is shown in 2016 US cents.

text:
This plot shows that, despite the rise in the nominal cost of a first-class stamp, the adjusted cost of the stamp has stayed relatively stable.
The large jumps in the early 1900s are because a change by a single penny was large compared to the cost of the stamp.
For example, the price increase from $0.02 to $0.03 on July 6, 1932 was a 50% increase in cost.
Additionally, while the cost of the stamp itself remained fixed, the adjusted price in 2016 dollars was not fixed over time which added to larger jumps in adjusted prices.

text: Historical notes[edit]

text: Domestic parcel post service was adopted in 1913, 25 years after the Post Office had agreed to deliver international parcel post packages pursuant to the Universal Postal Union treaty and various bilateral agreements with other nations.[17] Initially, there were no or few postal regulations governing packages mailed by parcel post. E.g., to construct a bank in Vernal, Utah, in 1916, a Salt Lake City company ascertained that the cheapest way to send 40 tons of bricks to the building was by parcel post.[18]

text: Bulk postal rates were restructured in 1996:[citation needed]

text:
Second Class became Periodicals
Third and Fourth Class Mail became Standard Mail (A) and (B)
Special Fourth Class Mail was renamed Special Standard Mail

text: In 2007, First Class Mail was restructured to include variable pricing based on size, not just on weight.  Shape-based postage pricing is a form of dimensional weight. Also at that time, International Parcel Post air service was re-branded as Priority Mail International, and Parcel Post surface service was discontinued for international destinations.[19]

text: Regular Air Mail service began in 1918 and over the years rates varied considerably depending on distance and technology. Domestic Air Mail, as a class of service, officially ended May 1, 1977. By that time all domestic First Class Mail was being dispatched by the most expeditious means, surface or air, whether or not the Air Mail postage had been paid.[citation needed]

text: Additional charges for Special delivery existed from 1885 to 2001. Today, Express Mail Overnight is the most similar service level.[citation needed]

text: During the summer of 2010 the USPS requested the Postal Regulatory Commission to raise the price of a first class stamp by 2 cents, from 44 cents to 46 cents, to take effect January 2, 2011. On September 30, 2010, the PRC formally denied the request, but the USPS filed an appeal with the Federal Court of Appeals in Washington DC.[20][21]

text: On September 25, 2013, the USPS announced a 3 cent increase in the First Class postal rate, to be effective January 26, 2014, increasing the price of a stamp to 49 cents. Bulk mail, periodicals, and package service rates were also increased by 6 percent. A loss of US$5 billion during the 2013 fiscal year was the reason given for the increase.[22]

text: The legislation which set the price to 49 cents was enacted as a temporary measure and as an "exigent surcharge for mailing products and services".[23] However, this legislation was set to expire in April 2016. As a result, the Post Office retained one cent of the price change as a previously allotted adjustment for inflation, but the price of a first class stamp became 47 cents: for the first time in 97 years (and for the third time in the agency's history[24]), the price of a stamp decreased.


document_title: List of Rock and Roll Hall of Fame inductees

question_text: when was led zeppelin inducted into hall of fame

text: Inductees[edit]

text: Performers[edit]

text: The performers category is meant for recording artists and bands that have "influence and significance to the development and perpetuation of rock and roll."[2] Artists become eligible for induction in that category 25 years after the release of their first record. In order to be inducted, an artist must be nominated by a committee that selects anywhere from nine to a dozen candidates. Ballots are sent to 600 "rock experts" who then evaluate the candidates and vote on who should be inducted. The performers who receive the highest number of votes and more than 50 percent of the vote are inducted. In 2011, the number inducted was five. The rest of the categories are voted on by special committees.[2] In 2012, six additional bands and groups were inducted as performers by a special committee, due to the controversial nature of their band being excluded when their lead singer was inducted. "There was a lot of discussion about this," said Terry Stewart, a member of the nominating committee. "There had always been conversations about why the groups weren't included when the lead singers were inducted. Very honestly, nobody could really answer that question – it was so long ago... We decided we'd sit down as an organization and look at that. This is the result."[10]

text: Early influences[edit]

text: Artists inducted into the early influences category are those "whose music predated rock and roll but had an impact on the evolution of rock and roll and inspired rock's leading artists."[2] Unlike the performers category, these inductees are selected by a committee. The full process is not transparent and it is unclear who comprises this selection committee.[2]

text: Non-performers (Ahmet Ertegun Award)[edit]

text: The non-performer category honors "songwriters, producers, disc jockeys, record executives, journalists and other industry professionals who have had a major influence on the development of rock and roll."[2] Several of the inductees in this category were in fact prominent performers as well. The inductees in this category are selected by the same committee that chooses the early influences. The full process is not transparent and it is unclear who comprises this selection committee.[2] This category has been criticized for inducting those that have "been coming to the dinner for years and paying for their tickets" and not revealing their full criteria.[140] In 2008, this category was renamed the "Ahmet Ertegün Award".[141]

text: Sidemen[edit]

text: Established in 2000, the sidemen category "honors those musicians who have spent their careers out of the spotlight, performing as backup musicians for major artists on recording sessions and in concert." A separate committee, composed mainly of producers, chooses the inductees.[2] In 2010, the category was renamed to "Award for Musical Excellence". According to Joel Peresman, the president of the Rock and Roll Hall of Fame Foundation, "This award gives us flexibility to dive into some things and recognize some people who might not ordinarily get recognized."[143]

text: Multiple inductees[edit]

text: As of 2017, 22 performers have been inducted twice or more; fourteen have been recognized as a solo artist and with a band and seven have been inducted with two separate bands. Eric Clapton is the only one to be inducted three times: as a solo artist, with Cream and The Yardbirds.[159] Clyde McPhatter was the first to ever be inducted twice and is one of three artists to be inducted first as a solo artist and then as a member of a band, the other artists being Neil Young and Rod Stewart. Stephen Stills is the only artist to be inducted twice in the same year. Crosby, Stills & Nash, inducted in 1997, is the only band to see all of its inducted members be inducted with other acts: David Crosby with The Byrds in 1991, Stephen Stills with Buffalo Springfield in 1997, and Graham Nash with The Hollies in 2010. The Beatles, inducted in 1988, is the second band to have all of its members be inducted, as well as the only band to have each of its members be inducted for their solo careers as their second induction. Ringo Starr is the first inductee to be inducted twice in different categories (The Beatles were inducted in the performers category in 1988 and Starr was inducted as a solo artist in the Award for Musical Excellence category in 2015). He also holds the record for the longest time between first and second inductions, at 27 years. Both of Stills' inductions happened during the 1997 ceremony and Clapton and McPhatter were inducted in back-to-back years (1987/88 for McPhatter, 1992/93 for Clapton, as well as his solo induction in 2000). The Traveling Wilburys are the only band to have all of its members be inducted without the band itself having been inducted: Roy Orbison as a solo artist in 1987, Bob Dylan as a solo artist in 1988, George Harrison with the Beatles in 1988 and as a solo artist in 2004, Tom Petty with Tom Petty and the Heartbreakers in 2002, and Jeff Lynne with the Electric Light Orchestra in 2017.

document_title: PR interval

question_text: what is the significance of the pq interval

text: PR interval

text:
In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200ms in duration.
The PR interval is sometimes termed the PQ interval.

text: Interpretation[edit]

text: Variations in the PR interval can be associated with certain medical conditions:

text:
Duration
A long PR interval (of over 200 ms) may indicate a first degree heart block.[1] Prolongation can be associated with hypokalemia, acute rheumatic fever,[2] or carditis associated with Lyme disease.[3]
A short PR interval (of less than 120ms) may be associated with Wolff–Parkinson–White syndrome, Lown–Ganong–Levine syndrome, or Junctional rhythms.
A variable PR interval may indicate other types of heart block.[citation needed]
PR segment depression may indicate atrial injury[4] or pericarditis.[5]
Variable morphologies of P waves in a single EKG lead is suggestive of an ectopic pacemaker rhythm such as wandering pacemaker or multifocal atrial tachycardia.[citation needed]


document_title: Microchip implant (animal)

question_text: where is the microchip placed in a dog

question_tokens: where is the microchip placed in a dog

text: Microchip implant (animal)

text: Uses and benefits[edit]

text: Animal shelters, animal control officers and veterinarians routinely look for microchips to return lost pets quickly to their owners, avoiding expenses for housing, food, medical care, outplacing and euthanasia. Many shelters place chips in all outplaced animals.

text: Microchips are also used by kennels, breeders, brokers, trainers, registries, rescue groups, humane societies, clinics, farms, stables, animal clubs and associations, researchers, and pet stores.

text: Some pet doors can be programmed to be activated by the microchips of specific animals, allowing only certain animals to use the door.[1]

text: Some countries require microchips in imported animals to match vaccination records. Microchip tagging may also be required for CITES-regulated international trade in certain endangered animals: for example, Asian Arowana are tagged to limit import to captive-bred fish.  Also, birds not banded who cross international borders as pets or for trade must be microchipped so that each bird is uniquely identifiable.

text: Usage[edit]

text: Microchips can be implanted by a veterinarian or at a shelter. After checking that the animal does not already have a chip, the vet or technician injects the chip with a syringe and records the chip's unique ID. No anesthetic is required it is a simple procedure and causes little discomfort: the pain is minimal and short-lived[2]. A test scan ensures correct operation.

text: An enrollment form is completed with chip ID, owner contact information, pet name and description, shelter and/or veterinarian contact information, and an alternate emergency contact designated by the pet owner. Some shelters and vets designate themselves as the primary contact to remain informed about possible problems with the animals they place. The form is sent to a registry, who may be the chip manufacturer, distributor or an independent entity such as a pet recovery service. Some countries have a single official national database. For a fee, the registry typically provides 24-hour, toll-free telephone service for the life of the pet. Some veterinarians leave registration to the owner, usually done online, but a chip without current contact information is essentially useless.

text: The owner receives a registration certificate with the chip ID and recovery service contact information. The information can also be imprinted on a collar tag worn by the animal. Like an automobile title, the certificate serves as proof of ownership and is transferred with the animal when it is sold or traded; an animal without a certificate could be stolen.

text: Authorities and shelters examine strays for chips, providing the recovery service with the ID number, description and location so they may notify the owner or contact.  If the pet is wearing the collar tag, the finder does not need a chip reader to contact the registry. An owner can also report a missing pet to the recovery service, as vets look for chips in new animals and check with the recovery service to see if it has been reported lost or stolen.

text: Many veterinarians scan an animal's chip on every visit to verify correct operation. Some use the chip ID as their database index and print it on receipts, test results, vaccination certifications and other records.

text: Some veterinary tests and procedures require positive identification of the animal, and a microchip may be acceptable for this purpose as an alternative to a tattoo.

text: Components of a microchip[edit]

text: A microchip implant is a passive RFID device. Lacking an internal power source, it remains inert until it is powered by the scanner or other power source.

text: Most implants contain three elements: a 'chip' or integrated circuit; a coil inductor, possibly with a ferrite core; and a capacitor. The chip contains unique identification data and electronic circuits to encode that information. The coil acts as the secondary winding of a transformer, receiving power inductively coupled to it from the scanner. The coil and capacitor together form a resonant LC circuit tuned to the frequency of the scanner's oscillating magnetic field to produce power for the chip. The chip then transmits its data back through the coil to the scanner.

text: These components are encased in biocompatible soda lime or borosilicate glass and hermetically sealed. Datamars has also started selling polymer microchips that are being implanted in pets.[3].

text: Implant location[edit]

text: In dogs and cats, chips are usually inserted below the skin at the back of the neck between the shoulder blades on the dorsal midline. According to one reference, continental European pets get the implant in the left side of the neck.[4] The chip can often be felt under the skin. Thin layers of connective tissue form around the implant and hold it in place.

text: Horses are microchipped on the left side of the neck, halfway between the poll and withers and approximately one inch below the midline of the mane, into the nuchal ligament.

text: Birds are implanted in their breast muscles. Proper restraint is necessary so the operation requires either two people (an avian veterinarian and a veterinary technician) or general anesthesia.

text: Implanted microchips can distort magnetic resonance imaging (MRIs), including those of the spinal cord.[5]

text: Animal species[edit]

text: Many animal species have been microchipped, including cockatiels and other parrots, horses, llamas, alpacas, goats, sheep, miniature pigs, rabbits, deer, ferrets, penguins, sharks, snakes, lizards, alligators, turtles, toads, frogs, rare fish, chimpanzees, mice, and prairie dogs—even whales and elephants.  The U.S. Fish and Wildlife Service uses microchipping in its research of wild bison, black-footed ferrets, grizzly bears, elk, white-tailed deer, giant land tortoises and armadillos.

text: Worldwide use[edit]

text:
Microchips are not yet universal, but they are legally required in some jurisdictions such as the state of New South Wales, Australia[6]
and the United Kingdom (for dogs, since 6 April 2016[7]).

text: Some countries, such as Japan, require ISO-compliant microchips or a compatible reader on imported dogs and cats.[8]

text: In New Zealand, all dogs first registered after 1 July 2006 must be microchipped. Farmers protested that farm dogs should be exempt, drawing a parallel to the Dog Tax War of 1898.[9] Farm dogs were exempted from microchipping in an amendment to the legislation passed in June 2006.[10] A National Animal Identification and Tracing scheme in New Zealand is currently being developed for tracking livestock.

text: In April 2012 Northern Ireland became the first part of the United Kingdom to require microchipping of individually licensed dogs.[11] Dog microchipping became mandatory in England on 6 April 2016.[12]

text: In Israel, microchips in dogs are mandatory.[citation needed]

text: Australia has a National Livestock Identification System.

text: The United States uses the National Animal Identification System for farm and ranch animals other than dogs and cats. In most species except horses, an external eartag is typically used in lieu of an implant microchip. Eartags with microchips or simply stamped with a visible number can be used. Both use ISO 15 digit microchip numbers with the U.S. country code of 840.

text: Cross-compatibility and standards issues[edit]

text: In most countries, pet ID chips adhere to an international standard to promote compatibility between chips and scanners. In the United States, however, three proprietary types of chips compete along with the international standard. Scanners distributed to United States shelters and veterinarians well into 2006 could each read at most three of the four types. Scanners with quad-read capability are now available and are increasingly considered required equipment.  Older scanner models will be in use for some time, so United States pet owners must still choose between a chip with good coverage by existing scanners and one compatible with the international standard. The four types include:

text:
The ISO Conformant Full Duplex type has the greatest international acceptance. It is common in many countries including Europe (since the late 1990s) and Canada. It is one of two chip protocol types (along with the "Half Duplex" type sometimes used in farm and ranch animals) that conform to International Organization for Standardization standards ISO 11784 & 11785. To support international/multivendor application, the 3-digit country code can contain an assigned ISO country code or a manufacturer code from 900 to 998 plus its identifying serial number.[Note 1]  In the United States, distribution of this type has been controversial. When 24PetWatch.com began distributing them in 2003 (and more famously Banfield Pet Hospitals in 2004) many shelter scanners couldn't read them.  (Some still can't; asking local shelters about this is still a good idea.)  At least one Banfield-chipped pet was inadvertently euthanized.[13]
The Trovan Unique type is another pet chip protocol type in use since 1990 in pets in the United States.[14] Patent problems forced the withdrawal of Trovan's implanter device from United States distribution and they became uncommon in pets in the United States, although Trovan's original registry database "infopet.biz" remained in operation. In early 2007, the American Kennel Club's chip registration service, AKC Companion Animal Recovery Corp, which had been the authorized registry for HomeAgain brand chips made by Destron/Digital Angel, began distributing Trovan chips with a different implanter. These chips are read by the Trovan, HomeAgain (Destron Fearing), and Bayer (Black Label) readers. Despite multiple offers from Trovan to AVID [15] to license the technology to read the Trovan chips, AVID continues to distribute readers that do not read Trovan or the ISO compliant chips.
A third type sometimes known as FECAVA or Destron[Note 2] is available under various brand names. These include, in the United States, "Avid Eurochip", the common current 24PetWatch chips, and the original (and still popular) style of HomeAgain chips.  (HomeAgain and 24Petwatch can  now supply the true ISO chip instead on request.) Chips of this type have 10 digit [hexadecimal] chip numbers. This "FECAVA" type is readable on a wide variety of scanners in the United States and has been less controversial, although its level of adherence to the ISO standards is sometimes exaggerated in some descriptions.[16][17][18]  The ISO standard has an annex (appendix) recommending that three older chip types be supported by scanners, including a 35-bit "FECAVA"/"Destron" type.[19] The common Eurochip/HomeAgain chips don't agree perfectly with the annex description, although the differences are sometimes considered minor.[Note 3]  But the ISO standard also makes it clear[Note 4] that only its 64-bit "full-duplex" and "half-duplex" types are "conformant"; even chips (e.g., the Trovan Unique) that match one of the Annex descriptions are not. More visibly, FECAVA cannot support the ISO standard's required country/manufacturer codes. They may be accepted by authorities in many countries where ISO-standard chips are the norm, but not by those requiring literal ISO conformance.
Finally, there's the AVID brand Friendchip type, which is peculiar due to its encryption characteristics.  Cryptographic features are not necessarily unwelcome; few pet rescuers or humane societies would object to a design that outputs an ID number "in the clear" for anyone to read, along with authentication features for detection of counterfeit chips, but the authentication in "Friendchips" has been found lacking and rather easy to spoof to the AVID scanner. Although no authentication encryption is involved, obfuscation requires proprietary information to convert transmitted chip data to its original label ID code. Well into 2006, scanners containing the proprietary decryption were provided to the United States market only by AVID and Destron/Digital Angel; Destron/Digital Angel put the decryption feature in some, but not all, of its scanners, possibly as early as 1996. (For years, its scanners distributed to shelters through HomeAgain usually had full decryption, while many sold to veterinarians would only state that an AVID chip had been found.)  Well into 2006, both were resisting calls from consumers and welfare group officials to bring scanners to the United States shelter community combining AVID decryption capability with the ability to read ISO-compliant chips. Some complained[20] that AVID itself had long marketed combination pet scanners compatible with all common pet chips except possibly Trovan outside the United States. By keeping them out of the United States, it could be considered partly culpable in the missed-ISO chips problem others blamed on Banfield.[Note 5]  In 2006, the European manufacturer Datamars, a supplier of ISO chips used by Banfield and others, gained access to the decryption secrets and began supplying scanners with them to United States customers. This "Black Label" scanner was the first four-standard full-multi pet scanner in the United States market. Later in 2006, Digital Angel announced[21] that it would supply a full-multi scanner in the United States.[Note 6] In 2008 AVID announced a "breakthrough" scanner,[22] although as of  October 2010[update] AVID's is still so uncommon that it's unclear whether it supports the Trovan chip. Trovan also acquired the decryption technology in 2006 or earlier, and now provides it in scanners distributed in the United States by AKC-CAR.  (Some are quad-read, but others lack full ISO support.)

text: Numerous references in print state that the incompatibilities between different chip types are a matter of "frequency". One may find claims that early ISO adopters in the United States endangered their customers' pets by giving them ISO chips that work at a "different frequency" from the local shelter's scanner, or that the United States government considered forcing an incompatible frequency change. These claims were little challenged by manufacturers and distributors of ISO chips, although later evidence suggests the claims were disinformation. In fact, all chips operate at the scanner's frequency. Although ISO chips are optimized for 134.2 kHz, in practice they are readable at 125 kHz and the "125 kHz" chips are readable at 134.2 kHz.  Confirmation comes from government filings that indicate the supposed "multi-frequency" scanners now commonly available are really single-frequency scanners operating at 125, 134.2 or 128 kHz. In particular, the United States HomeAgain scanner didn't change excitation frequency when ISO-read capability was added; it's still a single frequency, 125 kHz scanner.[23]

text: (For users requiring Shelter-Grade certainty, this table is not a substitute for testing the scanner with a set of specimen chips.  One study[37] cites problems with certain Trovan chips on the Datamars Black Label scanner. In general, the study found none of the tested scanners to read all four standards without some deficiency. The study predates the most recent scanner models, however.)

text: Reported adverse reactions[edit]

text: RFID chips are used in animal research, and at least three studies conducted since the 1990s have reported tumors at the site of implantation in laboratory mice and rats.[38] Noted veterinary associations[39] responded with continued support for the procedure as reasonably safe for cats and dogs, pointing to rates of serious complications on the order of one in a million in the U.K., which has a system for tracking such adverse reactions and has chipped over 3.7 million pet dogs. A recent study found no safety concerns for microchipped animals with RFID chips undergoing MRI at one Tesla magnetic field strength.[40] In 2011 a microchip-associated fibrosarcoma was reported found in the neck of a 9-year old, neutered-male cat. Histological examination was consistent with postinjection sarcoma, but all prior vaccinations occurred in the hindlegs.[41]

text: The microchip is implanted in the subcutaneous tissues causing an inflammatory response until scar tissue develops around the microchip. Studies on horses [42] are used as the basis for short inflammatory response claims, while procedures on done on small kittens and puppies.  Humans are reporting swelling and bruising at the time of implant with itching and pinching sensations for up to two years.[43]  The broader impacts on inflammatory disorders and cancer have not been determined and most of the health risks that were defined in the FDA Guidance developed for human implants [44] should be considered.  Adverse event reporting in the US can be made by the pet owner or a veterinarian to the FDA. https://www.fda.gov/AnimalVeterinary/SafetyHealth/ReportaProblem/ucm055305.htm

text: Adverse event reporting for animal microchips has been inconsistent. The UK’s Veterinary Medicines Directorate (VMD) assumed the task of adverse event reporting for animal microchips there in April 2014.  Mandatory microchipping of dogs and mandatory adverse event reporting went into effect in the UK in February of 2015.  The first report was issued for the period of April 2014 through December 2015 [45]. There were 1,500 adverse events reported for an unknown number of pets.  The estimate for the total cat and dog population of the UK is 16 million with 8.5 million dogs subject to mandatory microchipping. 4.5% of the adverse events are from adverse reactions and most of the rest from scanner failures and migration.  Microchip Adverse Event Reports for 2016 and 2017 do not appear to have been released.
