The title compound, C24H29NO4, is the product of a Petrenko-Kritchenko condensation of 1,5-bis-(2-formyl-phen-oxy)-3-oxa-pentane, pentan-3-one and methyl-ammonium acetate in ethanol. The mol-ecule has mirror symmetry. The aza-14-crown-3 ether ring adopts a bowl conformation stabilized by a weak intra-molecular C-H⋯O hydrogen bond. The conformation of the C-O-C-C-O-C-C-O-C polyether chain is t-g...

Micro-electro-mechanical Systems (MEMS) are components with micron-scale moving parts based on materials and processes of microelectronics fabrication. This is a good example of on-chip integration of electronics, microstructures, microsensors and microactuators. Accurate simulation of MEMS requires precise modeling of all effects of mechanical and damping forces, electrostatic forces and inner...

The paper examines the methodological principles of the psychological study of ecological consciousness as one of the urgent interdisciplinary problems of XX–XXI century, caused by the aggravation of global ecological problems and the need for the realization of the “sustainable development”ideas. Ecological consciousness is considered as multilayered, dynamic, reflexive element of human consci...

Neurexophilin was discovered as a neuronal glycoprotein that is copurified with neurexin Ialpha during affinity chromatography on immobilized alpha-latrotoxin (Petrenko et al., 1996). We have now investigated how neurexophilin interacts with neurexins, whether it is post-translationally processed by site-specific cleavage similar to neuropeptides, and whether related neuropeptide-like proteins ...

We present a 60-year record of the stable isotopes of atmospheric carbon monoxide (CO) from firn air samples collected under the framework of the North Greenland Eemian Ice Drilling (NEEM) project. CO concentration, δ13C, and δ18O of CO were measured by gas chromatography/isotope ratio mass spectrometry (gc-IRMS) from trapped gases in the firn. We applied LGGE-GIPSA firn air models (Witrant et ...

cules resembling neuropeptides (Petrenko et al., 1996; Neurexins are expressed in hundreds of isoforms on Missler and Südhof, 1998b). Single LNS domains are the neuronal cell surface, where they may function sufficient for ligand binding. b-neurexin containing a as cell recognition molecules. Neurexins contain LNS sole LNS domain binds a-latrotoxin and neuroligin (Ichtdomains, folding units fou...

The title compound, C26H32N2O4(M)·C2H4O2, (I), is the product of the Petrenko-Kritchenko condensation of N-propyl-piperidinone with 1,5-bis-(2-formyl-phen-oxy)-3-oxa-pentane and ammonium acetate. In M, the aza-14-crown-3-ether ring adopts a bowl conformation, with the configuration of the C-O-C-C -O-C-C-O-C polyether chain being t-g ((-))-t-t-g ((+))-t (t = trans, 180°; g = gauche, ±60°). The d...

The coronavirus outbreak is a global event that has bypassed national borders and affected the entire world. Therefore, examining social representations of can reveal problems structure peoples experiences in particular context. To identify coronavirus, authors conducted survey within territory Sverdlovsk region. covered period from March 11 to May 11, 2020. data were collected two stages: at f...
