Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen
Physik in unserer Zeit, EarlyView.Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.

Finite Temperatur Dynamic Susceptibility of the Free Bose Gas
, 2001 A detailed calculation of the real part of the finite temperature dynamic susceptibility of the free Bose gas is presented. After a short discussion on the different ways in which it can be calculated for temperatures above and below the Bose--Einstein ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Stream temperature‐equilibrium temperature relationship [PDF]
Water Resources Research, 2003 Equilibrium temperature is the water temperature at which the sum of all heat fluxes through the water surface is zero. It can be calculated from weather data. Mean weekly stream temperature was found to be linearly related to mean weekly equilibrium temperature above 0°C.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...
