On the localized wave patterns supported by convection-reaction-diffusion equation
A set of traveling wave solution to convection-reaction-diffusion equation is
studied by means of methods of local nonlinear analysis and numerical
simulation. It is shown the existence of compactly supported solutions as well
as solitary waves within this family for wide range of parameter values
Isomers and odor or nose as stereochemist
Nasz zmys艂 powonienia jest w stanie rozpozna膰 wiele zapach贸w, kt贸re pozornie s膮 bardzo do siebie podobne. Dzi臋ki temu, 偶e receptory w臋chowe s膮 w pewien spos贸b selektywne mo偶liwe jest ozr贸偶nienie zapach贸w zar贸wno enancjomerycznych par lotnych substancji jak i innych stereoizomer贸w. W niniejszej pracy przedstawione zosta艂y r贸偶nice i podobie艅stwa w艂a艣ciwo艣ci pachowych
izomer贸w przestrzennych. Przedstawione zwi膮zki charakteryzuj膮 si臋 odmiennym zapachem oraz intensywno艣ci膮 ale s膮 r贸wnie偶 takie, gdzie zmiana dotyczy tylko jednej z tych cech.Our sense of smell is able to recognize a variety of scents, which apparently are very similar. Thus olfactory receptors that are in some way it is possible to distinguish selective enantiomeric pairs fragrances and other volatile substances stereoisomers. This paper presents the differences and similarities odor characteristics of spatial isomers. The compounds are characterized by a different odor and intensity but also those where the change affects only one feature
