Environmental change drives demographic and evolutionary processes that determine diversity within and among species.Tracking these processes during periods of change reveals mechanisms for the establishment of populations and provides predictive data on response to potential future impacts, including those caused by anthropogenic climate change.He

Background.Mechanics of multicomponent and multiphase media is a branch of fluid and gas mechanics.Mathematical modeling of the dynamics of inhomogeneous media is of great importance due to the garmin 67 fact that the experimental study of many of these processes is difficult.At the same time, many models are essentially non-linear, for this reason
Hierarchically structured 3-dimensional electrodes based on branched carbon nanotubes (CNTs) are prepared on a glassy carbon (GC) substrate in a sequence of electrodeposition and chemical vapor deposition (CVD) steps as follows: Primary CNTs are grown over electrodeposited iron by CVD followed by a second Fe deposition and finally the CVD growth of
