In order to find the susceptibility of the Claisen rearrangement and next proton shift reaction of ally) aryl etherto the substiment effects in pan position, the kinetic and the:rmodynamie parameters are calculated at The33 LTP level using 6-3110. b asis set. The calculated activation energies for the rearrangements and protonshift reactions are around 3133 kcaUmol and 52.16 kcal/mol, nap.. liv...

C2-symmetric diimine generated in situ from (R,R)-HPEN and 8-formylquinoline was readily transformed to novel chiral pre-III bearing 1(S),2(S)-bis(quinolin-8-yl) ethane salicylic aldehyde fragments via stereoselective diaza-Cope rearrangement. The structure absolute configuration of the product established by X-ray diffraction study corresponding Rh(III) complex. In presence pre-III, practicall...

objective: group a rotaviruses (garv) are responsible for the vast majority of severe diarrhea worldwide that kills an estimated 600,000-870,000 children annually. since infantile gastroenteritis is a main health problem, therefore diagnosis and treatment of this disease is crucial. gene rearrangements have been detected in vitro during serial passages of the virus at a high multiplicity of inf...

Awareness for promoting equality is gaining popular acclaim, and, as a consequence, the initiative to form an IEEE Antennas and Propagation Society (AP-S) Committee on Promoting Equality (COPE) momentum. The name of this committee aptly fits its motives, it gives us immense pleasure bring your attention via “COPE Corner” in Magazine.

As the world is about to find out whether or not our civilisation is up to the challenge of dealing with climate change, research shows a wide range of responses from other species, which may benefit or suffer from the change, and mitigate it or make it worse. Michael Gross reports.

(1) Use of vague, exaggerated or untestable claims—including: (a) assertion of imprecise claims and (b) use of obscurantist language. (2) Over-reliance on confirmation rather than refutation—including: (a) assertion of claims that cannot be falsified in the event that they are incorrect; (b) over-reliance on testimonials and anecdotes; (c) selective use of experimental evidence. (3) Lack of ope...
