A Molecular Dynamics Study on the Structure Characteristic of Calcium Silicate Hydrate (C-S-H) Gelsn two types of calcium silicate hydrate (C-S-H) gels, namely, C-S-H(I) and C-S-H(II). Our simulations indicate that, in accordance with experiments, two types of C-S-H gels both present the structural characteristics of short-range ordered but long-range disordered. Furthermore, by an analysis of th

Steady-state phytoplankton assemblages in shallow Bulgarian wetlands,lgarian natural wetlands. They all differ in their morphometry, hydrology and trophic state. Steady states were identified according to Sommer & Padisák (1993) when (i) 1, 2 or 3 species of algae contribute more than 80% of total biomass, (ii) their existence or coexistence persists for long enough

Can Mean Helicity Fluctuations Explain The Variability of The Solar Cycle?se shift and the logarithmic amplitude of the wave exhibit a correlated random walk, so that weaker (stronger) cycles last longer (shorter). The solar cycle data follow this prediction rather well. Mean helicity fluctuations are concluded to be an important source of solar cycle variability.
