Combining RapidEye Satellite Images and Forest Inventory Data for Assesment of Forest Biomass

The paper presents the results of estimation of growing stock volume and live biomass in forest stands using combination of forest inventory measurements, multispectral satellite images RapidEye and digital elevation model (DEM). In a context of classification of remote sensing data we considered two nonparametric methods – k-Nearest Neighbors (k-NN) and Random Forest (RF).

Determination of the Activation Energy of the Reaction of Photosynthesis in Chlorophyll Synthesizing Microalgae

The dynamics of absorption of carbon dioxide at corresponding temperature by microalgae Chlorella was studied. The results of experimental research will allow to calculate the energy of activating photochemical reaction and other values of kinetics of increase of microalgae within the limits of the investigating temperatures. The analytical dependence of coefficient of growth biomass on temperature within the limits of the investigating temperature was established. The stages of transport of carbon dioxide from air to internal volume of microalgae cell was determined through literature.
