Research activities related to the role of forests and forestry in climate change mitigation in Austria. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
Forests and forestry play important roles in Austria with its close to 50/ forest cover. This paper provides details about the Austrian forest carbon inventory, discusses briefly the sources and sinks accounted under the land use, land use change and ...

Self-organization and autonomous control of intralogistics systems in line with versatile production at Werk 150

open access: yesProceedings of the Conference on Production Systems and Logistics, 2020
The planning and control of intralogistics systems in line with versatile production systems of smart factories requires new approaches and methods to cope with changing requirements within future factories.

A note on withdrawal through a point sink in fluid of finite depth

open access: yes, 1996
Withdrawal flow through a point sink on the bottom of a fluid of finite depth is considered. The fluid is at rest at infinity, and a stagnation point is present at the free surface, directly above the point sink. Numerical solutions are computed by means

Organic carbon sink dynamics and carbon sink-source balance in global lakes during the Anthropocene

open access: yes
The carbon burial and greenhouse gas emissions of lakes are pivotal in the global carbon cycle to offset or accelerate global warming. However, their balance or the magnitude of anthropogenic increase of carbon burial remains uncertain in global lakes ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Towards an integrated scientific approach for carbon accounting in forestry. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
In the COST E21-Action ""Contribution of Forests and Forestry to Mitigate Greenhouse Effects"", emphasis is put on the quantification of carbon storage in the forest ecosystems and on the understanding of linkages between human activities and climate ...

A rational approximation to the evolution of a free surface during fluid withdrawal through a point sink

open access: yes, 2010
The time varying flow in which fluid is withdrawn from a reservoir through a point sink of variable strength beneath a free surface is considered. Asymptotic techniques are used to derive an approximate solution to the flow that is valid at intermediate ...

Real source-sink pair

open access: yes, 2012
This work is concerned with the interaction of a source-sink pair. The main parameters of the problem are source and sink flow rates, the axial and lateral separations of the source and sink, and the angle between the axes of source and sink.

Does the Application Flow Rate of Nutrient Solutions Prepared in Brackish Water Affect Coriander Production?

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Flow rates for applying nutrient solutions in hydroponic systems are empirically known, yet uncertainties remain regarding whether brackish water affects the optimal flow rate and, consequently, biomass production and allocation. This study evaluated whether variations in application flow rate affect coriander biomass when brackish water is ...

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]

open access: yesBiotechnologie, 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 ...
