Carbon sequestration in Danish forests. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000. [PDF]
Biotechnologie, Agronomie, Société et Environnement, 2000 The Danish national reports on land-use change and forestry has so far only considered C sequestration in existing forests and in afforestation areas on former arable land. The standing stock of wood in existing forests was 55.2 millions cubic m in 1990,

Entropy and Phase Coexistence in Clusters: Metals vs. Nonmetals
Entropy, 2010 Small clusters violate the Gibbs phase rule by exhibiting two or more phases in thermodynamic equilibrium over bands of temperature and pressure. The reason is the small number of particles comprising each system.

Forests and the national greenhouse gas inventory of Germany. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]
Biotechnologie, Agronomie, Société et Environnement, 2000 Since 1995, experiences have been gathered with the calculation of National Greenhouse Gas Inventories in Germany. Because only marginal changes of the total forested area occur in Germany, relevant changes of the balance of greenhouse gases in the ...

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Graphical representation of chemical periodicity of main elements through boxplot
Educación Química, 2018 Graphics play an important role in data analysis. Boxplots are powerful graphical representation of data that gives an overview and a numerical summary of a data set. In this paper boxplots are used to analyze the periodic trends of main elements.
