Several sets of OPLS parameters have been published. There is OPLS-ua (united atom), which includes hydrogen atoms next to carbon implicitly in the carbon parameters, and can be used to save simulation time. OPLS-aa (all atom) includes every atom explicitly.
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
3 Days to Kill is a 2014 action thriller film [2] directed by McG and written by Luc Besson and Adi Hasak. [3] It stars Kevin Costner, Amber Heard, Hailee Steinfeld, Connie Nielsen, Richard Sammel, and Eriq Ebouaney. [4] It was released on 21 February 2014, [5] received mixed reviews, and grossed $52.6 million against its $28 million budget.
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
7 Days to Die is a survival horror video game set in an open world developed by the Fun Pimps. It was released through early access for OS X and Windows on December 13, 2013, [ 1 ] and for Linux on November 22, 2014. [ 2 ]
Radioactive decay is a random process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed. [2] [3] [4] However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as a half-life.
OPLS-AA, MMFF, GBSA solvent model, conformational sampling, minimizing, MD. Includes the Maestro GUI which provides visualizing, molecule building, calculation setup, job launch and monitoring, project-level organizing of results, access to a suite of other modelling programs.
