AbstractThe dynamics of binary Near-Earth objects (NEO) are discussed and a simple model for the study of their dynamics is introduced. Main results on the motion and stability of binary asteroids are reviewed. The effect of perturbations external to the binary system, including solar gravity, solar radiation pressure, and planetary gravity, are considered.

Steel Core

The paper describes the core heating of ACSR (aluminum conductor steel—reinforced) conductor in stable operation under different environmental conditions. The calculations are greatly simplified in a steady state—we can calculate on a balance of power instead of a balance of energies. At a known surface, the temperature of the conductor due to solar radiation, natural convection, and joules heating as well as the temperature of the steel core were calculated, which is relevant for the tensile strength of the rope. Measurements of the surface of the conductor and the core rejected a simple model of heat transfer—it is also necessary to take into account empty air spaces between the wires of a rope. On the basis of measurements, a new model has given satisfactory compliance with the measured values.

Radiation Use

A simple model to predict seasonal growth in sugarbeet yield is presented. Time from sowing to the 'growth point date' (the date on which a plant contained 4 g sugar) is characterized by a temp. sum. The increase in sugar yield after this date is calculated from incoming solar radiation using an av. radiation use efficiency. Temp. sums and radiation use efficiencies were estimated for the 11 Dutch sugarbeet regions. (Abstract retrieved from CAB Abstracts by CABI’s permission)
