When consumed, the false morel's principal active agent, gyromitrin, is hydrolyzed into the toxic compound monomethylhydrazine ( MMH ).

A lethal dose of gyromitrin has been estimated to be 10 – 30 mg / kg for children and 20 – 50 mg / kg in adults.

Strains with much lower concentrations of gyromitrin have been discovered, and the fungus has been successfully grown to fruiting in culture.

The method, which involves acid hydrolysis of gyromitrin followed by derivatization with pentafluorobenzoyl chloride, has a minimum detectable concentration equivalent to 0. 3 microgram of gyromitrin per gram of dry matter.

Monomethylhydrazine, as well as its precursors methylformylhydrazine and gyromitrin and raw Gyromitra esculenta, have been shown to be carcinogenic in experimental animals.

Monomethylhydrazine, as well as its precursors methylformylhydrazine and gyromitrin and raw Gyromitra esculenta, have been shown to be carcinogenic in experimental animals.

A 1985 study reported that the stems of G. esculenta contained twice as much gyromitrin than the cap, and that mushrooms collected at higher altitudes contained less of the toxin than those collected at lower altitudes.

Raw Gyromitra are toxic due to the presence of gyromitrin, and it is not known if all of the toxin can be removed by parboiling.

Although the amount of gyromitrin present can be significantly reduced through parboiling, there is evidence that repeated consumption can increase risk of toxicity.

The gyromitrin is leached into the water where it will remain, therefore the parboiling water must be discarded and replaced with fresh water after each round of boiling.

If boiling the mushrooms indoors, care should be taken to ensure adequate ventilation, and, if symptoms of gyromitrin poisoning appear, immediately seek fresh air.

Toxic effects from gyromitrin may also be accumulated from sub-acute and chronic exposure due to " professional handling "; symptoms include pharyngitis, bronchitis, and keratitis.

Gyromitra esculenta contains levels of the poison gyromitrin that vary locally among populations ; although these mushrooms are only rarely involved in poisonings in either North America or Western Europe, intoxications are seen frequently in eastern Europe and Scandinavia.

Drying the mushrooms can also reduce the concentration of gyromitrin ; ten days of open air desiccation leads to the loss of 90 % of gyromitrin.

Even after boiling, small amounts of gyromitrin remain in the mushrooms.

Several Gyromitra species are traditionally considered very good edibles and several steps are available to remove gyromitrin from these mushrooms and allow their consumption.

However, false advertising and so-called " quack " advertisements became a problem, which ushered in the regulation of advertising content.

In 1997, at the invitation of Logitech CEO Pierluigi Zappacosta, Adams, wearing a wig and false mustache, successfully impersonated a management consultant and tricked Logitech managers into adopting a mission statement that Adams described as " so impossibly complicated that it has no real content whatsoever.

She seems content to be a perpetual student, however, until she meets Nick, seeing in him a real person under the false persona.

Something sayable must have content that is fully intelligible to a person without that person's knowing if it is true or false.

A vacuous truth is a truth that is devoid of content because it asserts something about all members of a class that is empty or because it says " If A then B " when in fact A is inherently false.

As such, the ideologic content of the data and information are determined by the vocabulary with which the messages are presented — how the messages are presented ; thereby determines the value of the information as “ reliable ” or “ unreliable ”, as “ true ” or “ false ”, for the recipient reader, listener, and viewer.

Not that false joy that dreams content

The letter pointed out several similarities between their work and " Cog ", and warned the agency that they were considering legal action on the basis of the " commercialisation and simplification of the film's content and the false impression that might have endorsed the use ".

* In the 2009 case of James " Jim " Brown v. Electronic Arts, Inc., the District Court of the Central District of California dismissed athlete Jim Brown's theory of false endorsement under the Lanham Act and determined that the First Amendment protects the unauthorized use of a trademark in an artistic work when the mark has artistic relevance to the work and does not explicitly mislead as to the source or content of the work.

Non-content base statistical means can help lower false positives because it looks at statistical means vs. blocking based on content / keywords.

Third, these false positives are not equally distributed: since content filtering is prone to reject legitimate messages on topics related to products frequently advertised in spam.

A statistical filter can also respond quickly to changes in spam content, without administrative intervention, as long as users consistently designate false negative messages as spam when received in their email.

Hindsight bias may cause memory distortion, where the recollection and reconstruction of content can lead to false theoretical outcomes.

The lower probability theory is favoured by critical rationalism because the higher the informative content of a theory the lower will be its probability, for the more information a statement contains, the greater will be the number of ways in which it may turn out to be false.

For instance, the historian Daniel C. Peterson, chairman of the LDS apologetics group Foundation for Ancient Research and Mormon Studies ( FARMS ) at Brigham Young University, suggested the Tanners ' willingness to debunk false documents regardless of their content was a sign of integrity:

They are often assumed to be the simplest components of thought and can express meanings or content that can be true or false.

Popper called his ' principle of rationality ' nearly empty ( a technical term meaning without empirical content ) and strictly speaking false, but nonetheless tremendously useful.

Even while praising Gladwell's attractive writing style and content, Pinker sums up Gladwell as " a minor genius who unwittingly demonstrates the hazards of statistical reasoning ," while accusing him of " cherry-picked anecdotes, post-hoc sophistry and false dichotomies " in his book Outliers.
