Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Johannes Hjellbrekke (born 1965) is a Norwegian sociologist. He is Professor of Sociology at the University of Bergen and was editor-in-chief of Sosiologisk tidsskrift (the Norwegian Journal of Sociology) from 2003 to 2005.
To prevent decomposition, the xenon tetroxide thus formed is quickly cooled into a pale-yellow solid. It explodes above −35.9 °C into xenon and oxygen gas, but is otherwise stable. A number of xenon oxyfluorides are known, including XeOF 2, XeOF 4, XeO 2 F 2, and XeO 3 F 2. XeOF 2 is formed by reacting OF 2 with xenon gas at low temperatures.
In a 2023 study, anecdotal claims surrounding THC-O-acetate's supposed ability to initiate psychedelic experiences were shown to not be significant. Answers using the Mystical Experience Questionnaire (MEQ) were under the threshold of a true experience, and those who had used classical psychedelics such as LSD or psilocybin consistently scored lower on the MEQ.
RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
2.7 to 2.9 μm for hydrogen fluoride (<80% atmospheric transmittance) Chemical reaction in a burning jet of ethylene and nitrogen trifluoride (NF 3) Used in research for laser weaponry, operated in continuous-wave mode, can have power in the megawatt range. Deuterium fluoride laser ~3800 nm (3.6 to 4.2 μm) (~90% atm. transmittance) chemical ...
Orthomyxoviridae (from Ancient Greek ὀρθός (orthós) 'straight' and μύξα (mýxa) 'mucus') [1] is a family of negative-sense RNA viruses.It includes seven genera: Alphainfluenzavirus, Betainfluenzavirus, Gammainfluenzavirus, Deltainfluenzavirus, Isavirus, Thogotovirus, and Quaranjavirus.
Greenfoot is an integrated development environment using Java or Stride designed primarily for educational purposes at the high school and undergraduate level. It allows easy development of two-dimensional graphical applications, such as simulations and interactive games.
