Toxic units (TU) are used in the field of toxicology to quantify the interactions of toxicants in binary mixtures of chemicals. [1] A toxic unit for a given compound is based on the concentration at which there is a 50% effect (ex. EC50) for a certain biological endpoint.

This is a list of special types of claims that may be found in a patent or patent application.For explanations about independent and dependent claims and about the different categories of claims, i.e. product or apparatus claims (claims referring to a physical entity), and process, method or use claims (claims referring to an activity), see Claim (patent), section "Basic types and categories".
Title page of the Panegyric of Leonardo Loredan (1503), created in honour of Leonardo Loredan, 75th Doge of Venice, now in the Walters Art Museum in Baltimore. A panegyric (US: / ˌ p æ n ɪ ˈ dʒ ɪ r ɪ k / or UK: / ˌ p æ n ɪ ˈ dʒ aɪ r ɪ k /) is a formal public speech or written verse, delivered in high praise of a person or thing. [1]
Pliny's Panegyricus model is familiar to the authors of panegyrics 5, 6, 7, [18] 11, and especially 10, in which there are several verbal likenesses. Sallust's Bellum Catilinae is echoed in the panegyrics 10 and 12, and his Jugurthine War in 6, 5, and 12. [19] Livy seems to have been of some use in panegyric 12 [20] and Panegyric 8. [21]
A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.
The R1 (internally called XCON, for eXpert CONfigurer) program was a production-rule-based system written in OPS5 by John P. McDermott of Carnegie Mellon University in 1978 to assist in the ordering of DEC's VAX computer systems by automatically selecting the computer system components based on the customer's requirements.
Chemical synthesis (chemical combination) is the artificial execution of chemical reactions to obtain one or several products. [1] This occurs by physical and chemical manipulations usually involving one or more reactions. In modern laboratory uses, the process is reproducible and reliable.
