Normal Vibrations and Molecular Forms of Methyl Ethyl Sulfide.

cis-Dichloridobis(ethyl methyl sulfide-κS)oxidovanadium(IV)

The mononuclear title complex, [VCl2O(C3H8S)2], features a V(IV)=O double bond [1.5845 (15) Å] in an overall trigonal-bipyramidal coordination environment defined by two Cl(-) and the S atoms of two (CH3CH2)(CH3)S ligands. In the crystal, pairs of mol-ecules form centrosymmetric dimers via C-H⋯O hydrogen bonds between the methyl C-H group and the oxidovanadium O atom of a neighbouring mol-ecule.

The use of normal forms for analysing nonlinear mechanical vibrations

A historical introduction is given of the theory of normal forms for simplifying nonlinear dynamical systems close to resonances or bifurcation points. The specific focus is on mechanical vibration problems, described by finite degree-of-freedom second-order-in-time differential equations. A recent variant of the normal form method, that respects the specific structure of such models, is recall...

A Mouse Model of Acute and Delayed Complications of Sulfur Mustard Analogue, 2-Chloroethyl Ethyl Sulfide

Background: Numerous studies have been conducted on humans, animals, and cell cultures exposed to Sulfur Mustard (SM). However, the precise mechanism and cause or long-term pattern of SM injuries are not well defined. There is no protocol available for treating people with severe eye, lung, and skin ailments. The current study aimed to develop an animal model of the acute and delayed complicati...
