Isotopes of tellurium

There are 39 known isotopes and 17 nuclear isomers of tellurium (52Te), with atomic masses that range from 104 to 142. These are listed in the table below.

Naturally-occurring tellurium on Earth consists of eight isotopes. Two of these have been found to be radioactive: 128Te and 130Te undergo double beta decay with half-lives of, respectively, 2.2×1024 (2.2 septillion) years (the longest half-life of all nuclides proven to be radioactive) and 8.2×1020 (820 quintillion) years. The longest-lived artificial radioisotope of tellurium is 121Te with a half-life of about 19 days. Several nuclear isomers have longer half-lives, the longest being 121mTe with a half-life of 154 days.

The very-long-lived radioisotopes 128Te and 130Te are the two most common isotopes of tellurium. Of elements with at least one stable isotope, only indium and rhenium likewise have a radioisotope in greater abundance than a stable one.

It has been claimed that electron capture of 123Te was observed, but more recent measurements of the same team have disproved this. The half-life of 123Te is longer than 9.2 × 1016 years, and probably much longer.

124Te can be used as a starting material in the production of radionuclides by a cyclotron or other particle accelerators. Some common radionuclides that can be produced from tellurium-124 are iodine-123 and iodine-124.

The short-lived isotope 135Te (half-life 19 seconds) is produced as a fission product in nuclear reactors. It decays, via two beta decays, to 135Xe, the most powerful known neutron absorber, and the cause of the iodine pit phenomenon.

With the exception of beryllium, tellurium is the second lightest element observed to have isotopes capable of undergoing alpha decay, with isotopes 104Te to 109Te being seen to undergo this mode of decay. Some lighter elements, namely those in the vicinity of 8Be, have isotopes with delayed alpha emission (following proton or beta emission) as a rare branch.

Jeisa
One thing you could do is replace the copyright notice at Jeisa Chiminazzo with the content at Jeisa. It would be better to have her listed under her full name. The article Jesia could then be made into a redirect to Jeisa Chiminazzo or the Jesia could be deleted. Sorry about being so long in replying but I was babysitting and had no chance to get online.

WTKS-FM

WTKS-FM (104.1 MHz) is a commercial radio station licensed to Cocoa Beach, Florida, and serving Central Florida and Greater Orlando. It broadcasts a hybrid hot talk and alternative rock radio format. The station is owned and operated by iHeartMedia, Inc., with studios and offices is in Maitland, Florida).

WTKS-FM has an effective radiated power (ERP) of 100,000 watts, the maximum permitted for non-grandfathered FM stations. The transmitter tower is off Fort Christmas Road in Bithlo, Florida. WTKS-FM broadcasts using HD Radio technology. The HD2 digital subchannel carries a mainstream urban format known as "104.5 The Beat", which feeds FM translator W283AN at 104.5 MHz.

Programming
On weekdays, WTKS-FM broadcasts hot talk shows, aimed at a more youthful audience than would usually listen to conventional talk radio shows. Weekdays begin with "Monsters in the Morning", followed by "The News Junkie", "The Jim Colbert Show", "A Corporate Time with Tom & Dan" and "Real Laughs". From 10p.m. to early morning, WTKS-FM switches to alternative rock. Weekends also feature alternative rock, with some specialty shows on Sunday mornings and evenings.

Parent company iHeartMedia had picked some shows from WTKS-FM as part of XM Radio's Extreme XM channel 152. That service was discontinued in 2008.

History
The station first signed on the air on May 6, 1962. WRKT-FM originally had an automated beautiful music format, and was the sister station to WRKT (1300 AM, now WKQK). The station was owned by C. Sweet Smith. It played quarter hour sweeps of mostly instrumental cover versions of popular songs, as well as Broadway and Hollywood show tunes.

In 1967, the station changed formats to progressive rock with the new call sign WKPE. The station was initially automated, but eventually added live announcers. WKPE reverted to the WRKT call letters in 1977 with a Top 40 format as "Rocket 104", then shifting its format to adult contemporary in 1980.

Guy Gannett purchased WRKT-FM in 1981 with the intent of upgrading the 30,000-watt station to 100,000 watts from a new tower near Bithlo. The more powerful relocated tower would allow the station to serve the lucrative Orlando radio market. The call letters were changed that year to WSSP. A beautiful music format was planned, but WSSP initially adopted a country music format as Brevard's Stereo Country 104. The country format was a temporary measure until the upgrade of the station's signal could be finalized.

The move to Bithlo was completed in 1985, and WSSP became beautiful music WSSPer 104 ("whisper"). For a number of years, "WSSPer" was one of the most popular radio stations in Orlando, often ranking as the #1 station in the Arbitron ratings and posting shares as high as 17% in certain dayparts. However, by the early 1990s, the station's ratings were down, and after stunting with a robotic countdown, WSSP switched to a hot AC format as WZTU, U104.1, on May 3, 1991, in the hopes of raising ratings and revenue. "U104.1" failed miserably. Later that year, Gannett sold its radio stations in Orlando and Miami to concentrate on its television properties. WZTU was acquired by Paxson Communications Corporation, headed by Lowell "Bud" Paxson (founder of the Home Shopping Network and later PAX TV). After stunting with yet another robotic countdown, Paxson switched WZTU to CHR as WHVE "One Hundred-Four One, The Wave", at 7:45 a.m. on May 29, but despite the programming expertise of Bill Pasha of WAPE-FM in Jacksonville, ratings and revenues did not increase; the station came in 14th place in its first ratings book. "The Wave" format was dropped on August 17, 1992, after only just three months.

WHVE then changed its calls to WWNZ-FM, and began simulcasting WWNZ's talk format, though it would air a few separate shows. Paxson sold WWNZ-FM to Press Broadcasting, which also owned WKCF, in 1993. In May of that year, Press Broadcasting initiated the WTKS calls and the "Real Radio" format, which was talk shows during the week (including Howard Stern from May 1994 through February 2004 ) and alternative rock on the weekend. Real Radio was created by Sabo Media CEO Walter Sabo for Press Broadcasting. The station was sold back to Paxson in 1996 and then came under the umbrella of Clear Channel Communications (now iHeartMedia) in 1997. On June 21, 2007, Clear Channel announced the request of transfer for their entire Orlando cluster into the Aloha Station Trust upon the consummation of the impending company buyout.

WTKS held an annual "Kicks for Guns" program in association with the Orlando Police Department where citizens could exchange guns, no questions asked, for shoes. The program made international headlines when the 2007 exchange managed to net a surface-to-air rocket launcher.

WTKS-FM HD2 originally aired a simulcast of talk radio 540 WFLF, and the HD3 subchannel aired a simulcast of sports radio 740 WYGM. WTKS stopped simulcasting WYGM on the HD3 subchannel on May 6, 2012, with the WYGM simulcast moving to WJRR-HD2, resulting in the demise of "Channel X". On February 12, 2014, the WFLF simulcast moved from W283AN 104.5 to W273CA 102.5 (displacing smooth jazz), and WTKS-HD2 flipped to its current urban format as "The Beat", filling the void after long-time urban station WJHM flipped to Top 40 the previous day.

Previous shows
SBK Live originally aired from 7:00pm to 11:00pm Monday through Friday. After the show was cancelled Soul Brother Kevin moved back as a member of The Monsters in the Morning show.

The Buckethead Show with Buckethead (Jason Bailey). It originally aired from 11:00am to 3:00pm Monday through Friday. After the show was cancelled on June 26, 2013, Bailey went to CBS Radio's WZGC-FM in Atlanta to co-host The Morning Grind with Randy Cross and Kristen Ledlow.

Epistolæ Obscurorum Virorum

The Epistolæ Obscurorum Virorum (English: Letters of Obscure Men) was a celebrated collection of satirical Latin letters which appeared 1515–1519 in Hagenau, Germany. They support the German Humanist scholar Johann Reuchlin and mock the doctrines and modes of living of the scholastics and monks, mainly by pretending to be letters from fanatic Christian theologians discussing whether all Jewish books should be burned as un-Christian or not.

Background
The work was based upon the real-life public dispute between German humanist Johann Reuchlin and certain Dominican friars, especially the formerly Jewish convert Johannes Pfefferkorn who had obtained Imperial authority from Holy Roman Emperor Maximilian I to burn all known copies of the Talmud in 1509. The title is a reference to Reuchlin's 1514 book Epistolae clarorum virorum (English: Letters of famous/bright men) which provided a collection of letters to Reuchlin on scholarly and intellectual matters from eminent German humanists such as Ulrich von Hutten, Johann Crotus, Konrad Mutian, Helius Eobanus Hessus, and others, to show that his position in the controversy with the monks was approved by the learned. The Latin adjective obscurus ("dark, hidden, obscure") is the opposite of clarus ("bright, famous, obvious") used in the title of Reuchlin's book.

Structure and presumptive authors
Most of the letters found in Epistolæ Obscurorum Virorum are addressed to Hardwin von Grätz in Deventer and contain mock accusations against him, such as allegation that he had been intimate with Johannes Pfefferkorn's wife (Letter XII) and that Grätz had defecated his pants in public (letter XL). The letters profess to be written by certain ecclesiastics and professors in Cologne and other towns of Germany. Grätz had made himself odious to the liberal minds of the time by what they saw as his arrogant pretension, his determined hostility to the spirit of the age, and his lax morality.

The first issue of the work contained 41 letters, but more were added later. The collection was published anonymously, and the authorship has been a fertile subject of controversy, but the main portion of the letters are attributed to the humanists Crotus Rubeanus a.k.a. Johannes Jäger, who is said to have originated the idea and the title; Ulrich von Hutten, who contributed mainly to the second volume; Erasmus; and Reuchlin. The work is credited with hastening the Protestant Reformation.

Bans and papal excommunication
The book was banned in many places, and with regard to the rise of Martin Luther's Protestant Reformation, Pope Leo X excommunicated the authors, readers, and disseminators of the Epistolæ Obscurorum Virorum in 1517, citing the fact that the discussed matter of burning all Jewish books, especially the Talmud, was not held as a majority view among Christian scholars.

Legacy
The modern term obscurantism derives from the title of this work. As the theologians in the book intended to burn "un-Christian" works, Enlightenment philosophers used the term for conservative, especially religious enemies of progressive Enlightenment and its concept of the liberal spread of knowledge.

Watchdog journalism

Watchdog journalism is a form of investigative journalism where journalists, authors or publishers of a news publication fact-check and interview political and public figures to increase accountability in democratic governance systems.

Role
Watchdog journalists gather information about the actions of people in power and inform the public in order to hold elected officials to account. This requires maintaining a certain professional distance from people in power. Watchdog journalists are different from propagandist journalists in that they report from an independent, nongovernmental perspective. Due to watchdog journalism's unique features, it also often works as the fourth estate. The general issues, topics, or scandals that watchdog journalists cover are political corruption and any wrongdoing of people in power such as government officials or corporation executives.

Three dimensions of operationalization
The role of the press to be a "watchdog" and monitor a government's actions has been one of the fundamental components of a democratic society. Ettema and Glasser (1998) argue that watchdog journalism's most important role is that their “stories implicitly demand the response of public officials.” Playing a role as a Fourth Estate, watchdog journalism is able to force governments to meet their obligations to the public by publicizing issues such as scandals, corruption, and failure to address needs of the public. Mellado (2015) identified and developed three dimensions of operationalization of the watchdog role: the intensity of scrutiny, journalistic voice, and the source of news event.

 * Intensity of scrutiny: Watchdog journalism has a few levels of scrutiny in terms of its reporting style. First of all, at the lowest level, questions and interrogations are a key way to investigate people with power. At a next level, denunciation is still not necessarily needed. But it consists of more obvious and somewhat aggressive questions and interrogations. Lastly, the highest level of scrutiny involves the strategy which is designed for people who are investigated to confess their wrongdoing, which requires a variety of evidence of wrongdoing to be used.
 * Journalistic voice: Watchdog journalism needs a few types of voices which are required to address the scrutiny. Specifically, journalists' own voice or a third party's voice is the most general type. In the case of a detached orientation of watchdog journalism, it is likely to use a third party's voice to question, criticize, and denounce wrongdoings what people with power do rather than using journalists' voices.
 * Source of news event: There is a specific type of event that watchdog journalism is interested in to question, criticize, and denounce. Specifically, not only corruptions of the relationship between people with power and media, but also issues about judiciary processes or external investigations are likely to be handled by a detached orientation of watchdog journalism.

Predictors of watchdog role performance
Depending on the differences in a social and organizational level, a performance of the journalistic role also changes. In turn, there are a few factors that are likely to have an influence over the type of watchdog performance in the journalism.

 * Democracy: Watchdog journalism can work effectively in well-established democratic countries, owing to the high level of the freedom of the press, journalistic autonomy and independence. A low level of press censorship, state intervention, and institutional control are ensured at the same time.
 * Audience orientation: Audience orientation is one of the factors that affects the performance of journalistic roles. For instance, in China, market newspapers are more likely to play a role as the watchdog journalism than an official newspaper, which is supposed to publicize corruptions of people with power such as how they misuse existing policy or law, does. At this point, there is a huge difference in reporting styles between popular press and elite press.
 * Media political leaning: The political orientation of the journalism is closely associated to the performance of the watchdog role. To be specific, according to what Mellado et al. (2017) found in five Latin American countries, the media that serves the interests of the right or moderates is less likely to work as a watchdog than the media serving interests of the left. In addition, biased tendency of the media has a great impact on the coverage of the political issues or scandals.
 * News beats: The performance of the watchdog journalism is influenced by journalistic specialization. For instance, based on what Reich (2012) found, journalists who deal with political issues are highly likely to act as watchdogs than ones who cover business issues. Similar tendency appears in other countries including China, Chile, and Spain. To be specific, in these countries, watchdog journalism can be found in the field that covers the political scandals, while business and economy journalists are less likely to act as watchdog.

Detached watchdog
Detached watchdog journalism, one of the four identified journalism cultures, puts emphasis on neutrality, fairness, objectivity, and impartiality. This is the most familiar and pervasive type of a few forms of watchdog journalism. Detached watchdog refers to observing issues in a detached manner. So it pursues a different approach in scrutinizing wrongdoings and publicizing them to the public from what interventionist approach does. In addition this is the reason why characteristics including neutrality, fairness, objectivity, and impartiality are important. But it does not mean that watchdog journalists do not take a skeptical and critical action. The detached watchdog journalism is predominant especially in the western countries such as Germany, the United States, Austria, and Switzerland.

In the detached approach, the most predominant form of watchdog journalism, criticism and question which are done by sources are the least intense levels of scrutiny. Since the detached watchdog journalism generally consists of third parties (or sources) that question, criticize, and denounce wrongdoings, it tends to play a passive role in terms of investigating people in power. In this regard, one of the characteristics that distinguishes between detached and the other type of approaches named interventionist watchdog journalism is the type of event that journalists handle. The type of event that prompts the journalists to act as a watchdog to scrutinizing people in power by questioning and criticizing is different based on the approaches. Within liberal media systems, the phenomenon that journalists are highly likely to take the detached approach of the watchdog journalism can be often seen because of liberal media systems’ a few unique features such as the factuality and objectivity.

Indicators of detached orientation and operationalization

 * Questioning by sources: People other than journalists can question people in power by expressing opinions and giving statements or quotes.
 * Criticism by sources: People other than journalists can criticize those with power can through expressing negative opinions or giving a statement or quote.
 * Denunciation by sources: People other than journalists can provide a testimony or an evidence about something that people with power do and say.
 * External investigation: Corruptions, scandals, or issues of people in power are often scrutinized and covered by the news media even though journalists do not handle them directly.
 * Questioning by the journalist: Journalists can work as a watchdog by checking the legitimacy and integrity of people in power's action.
 * Criticism by the journalist: The journalists are allowed to judge and condemn what people in power do by making assertions.
 * Denunciation by the journalist: The journalists can denounce and accuse something that is hidden illegally by people in power by making assertions.
 * Reporting of conflict: The journalists can bring a source, an institution, or people in power that have to be scrutinized to the table.

In practice
Historically, a lot of examples have proven that watchdog journalism has the power to dislodge corrupt people in power from their positions. One of the most famous examples is how coverage of the Watergate scandal, done by watchdog journalists Bob Woodward and Carl Bernstein, led to resignation of the U.S. President Richard Nixon on August 9, 1974.

Washington Post's coverage of Watergate scandal
The Watergate scandal was one of the biggest political scandals in the United States. It involved Richard Nixon, the 37th president of the United States and led him to resign.

This scandal stemmed from the exposure of a burglary of the Democratic National Committee headquarters in the Watergate Office Building, Washington D.C. committed by 5 former FBI and CIA agents, who were paid to plant a bug to help Nixon's re-election campaign. After the 5 were arrested, investigative journalists Bernstein and Woodward gradually exposed more details of the plot in a series of stories in The Washington Post. Eventually in 1973 the U.S. House of Representatives decide to commence an impeachment process against Nixon. Audio tapes that Nixon had secretly made of events in the Oval Office revealed that Nixon tried to cover up details of the crime. As a result, the impeachment against Richard Nixon was approved by the House judiciary committee. He resigned from the presidency on August 9, 1974.

The role of Washington Post as watchdog journalism in the case of Watergate scandal
The case of Watergate scandal was a famous example showing the role of watchdog journalism, how it works, and its impact. The media, particularly The Washington Post, significantly contributed to highlighting the fact that a connection did exist between the breaking into of the Watergate Office and Richard Nixon's re-election committee, leading to an explosion of publicity and public attention. In order to cover the scandal, anonymous sources became the main material that The Washington Post relied on. However, Washington Post investigative journalists Bob Woodward and Carl Bernstein were significant contributors who uncovered information and evidence that proved the agents' break-in to plant a bug and attempts to conceal it, which then resulted in the intervention of the Justice Department, FBI, CIA, and the White House. Woodward and Bernstein also conducted interviews with witness Judy Hoback Miller, the bookkeep who worked at the Richard Nixon's re-election committee, to uncover evidence of conspiracy: Richard Nixon and his committee mishandling funds and destroying records. However, the most valuable and reliable source was an anonymous whistleblower nicknamed Deep Throat by Woodward and Bernstein. Every meeting between Washington Post investigative journalists and Deep Throat was held secretly. Through these meetings, Richard Nixon's, his committee's and the White House's involvement in the scandal were researched. It was later revealed that Deep Throat, the anonymous informant, was the 1970s FBI deputy director William Mark Felt, Sr.

Crisis in watchdog journalism

Journalism's role as a socio-political watchdog is threatened in many societies across the world. Due to watchdog journalism's ability to establish responsibility and handle corruption, particularly for those in power, it is often viewed as a dangerous and powerful tool. Since many local news media establishments and newspapers have faced closing or consolidation in recent years, watchdog journalism is in danger of extinction. In the United States, more than 1,400 cities in the last 15 years ago have seen independent local newspapers close, particularly cities where journalism that reported issues caused by corruption was needed. The phenomenon of disappearing watchdog journalism is observed to have negative outcomes for communities: for example, the dishonest actions of powerful societal figures like politicians are unable to be watched and criticized. Lack of transparency in these communities due to disappearing critical and independent journalism creates problems and stifles a healthy democracy.

In addition, disappearing of a local newspaper that plays a role as a watchdog journalism is related to putting a financial problem directly on members in a community. Based on the research conducted by the University of Illinois at Chicago and the University of Notre Dame, it is found that increasing in borrowing costs after a local newspaper is closed has a close connection with municipal government. It indicates that the absence of a watchdog journalism leaves the public out of a discussion and helps people in power such as government officials to refuse to meet public scrutiny. People in power are highly likely to engage in wasteful spending because there is no journalism that watches and criticizes their actions, decisions, and policies. To simply put, if there is no investigative journalism, important issues that public must know are not covered. So instead of reporting on fraud, abuse, and waste, useless and meaningless topics will be handled as if they are the only problem that a community faces. For instance, a corruption scandal which is related to various public infrastructures such as hospital that require more resources with a high quality to provide better service to public will be less likely to be told.

An extreme example is provided by the City of Bell scandal: Bell, California is a modest income community of roughly 37,000 in Los Angeles County. In 1999 or shortly thereafter the local newspaper died. In 2010 the Los Angeles Times found that the city was near bankruptcy in spite of having atypically high property tax rates. Part-time city council members collected almost $100,000 a year. The Chief of Police's salary was over $450,000, roughly double that of the Los Angeles Chief of Police, whose department included almost 10,000 officers vs. 48 for Bell. The city manager made almost $800,000, almost double that of the President of the United States.

Isotopes of antimony

Antimony (51Sb) occurs in two stable isotopes, 121Sb and 123Sb. There are 35 artificial radioactive isotopes, the longest-lived of which are 125Sb, with a half-life of 2.75856 years; 124Sb, with a half-life of 60.2 days; and 126Sb, with a half-life of 12.35 days. All other isotopes have half-lives less than 4 days, most less than an hour.

There are also many isomers, the longest-lived of which is 120m1Sb with a half-life of 5.76 days.

With the exception of beryllium, antimony is the lightest element observed to have isotopes capable of undergoing alpha decay, with the isotope 104Sb being seen to undergo this mode of decay. Some lighter elements, namely those in the vicinity of 8Be, have isotopes with delayed alpha emission (following proton or beta emission) as a rare branch.

Isotopes of tin

Tin (50Sn) is the element with the greatest number of stable isotopes (ten; three of them are potentially radioactive but have not been observed to decay). This is probably related to the fact that 50 is a "magic number" of protons. In addition, twenty-nine unstable tin isotopes are known, including tin-100 (100Sn) (discovered in 1994) and tin-132 (132Sn), which are both "doubly magic". The longest-lived tin radioisotope is tin-126 (126Sn), with a half-life of 230,000 years. The other 28 radioisotopes have half-lives of less than a year.

Tin-117m
Tin-117m is a radioisotope of tin. One of its uses is in a particulate suspension to treat canine synovitis (radiosynoviorthesis).

Tin-121m
Tin-121m (121mSn) is a radioisotope and nuclear isomer of tin with a half-life of 43.9 years.

In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce tin-121 at higher yields. For example, its yield from uranium-235 is 0.0007% per thermal fission and 0.002% per fast fission.

Tin-126
Tin-126 is a radioisotope of tin and one of the only seven long-lived fission products of uranium and plutonium. While tin-126's half-life of 230,000 years translates to a low specific activity of gamma radiation, its short-lived decay products, two isomers of antimony-126, emit 17 and 40 keV gamma radiation and a 3.67 MeV beta particle on their way to stable tellurium-126, making external exposure to tin-126 a potential concern.

Tin-126 is in the middle of the mass range for fission products. Thermal reactors, which make up almost all current nuclear power plants, produce it at a very low yield (0.056% for 235U), since slow neutrons almost always fission 235U or 239Pu into unequal halves. Fast fission in a fast reactor or nuclear weapon, or fission of some heavy minor actinides such as californium, will produce it at higher yields.
