Estimation of forest biomass has received much attention in recent decades. Airborne and spaceborne (SAR) have a great potential to quantify biomass and structural diversity because of its penetration capability. Polarizations are important elements in SAR systems due to sensitivity of them to backscattering mechanisms and can be useful to estimate biomass. Full Polarimetric Synthetic Aperture ...
In this study, species composition, density and biomass of zooplanktons including Rotatoria, Protozoa and Meroplanktons were sampled using Juday net with mesh size of 100 µ at depths of 5, 10 and 20 meters in southern Caspian Sea (Babolsar) in two seasons of cold (Feb. 2015) and warm (June 2015) . This study identified Asplanchna sp. and Synchaeta sp. from Rotatoria, and Balanus sp., Pelecypoda...

Biomass measurement is important in terms of ecological and economical evaluation of the structure and conditions of habitat and can provide an estimate for carbon sequestration in different organs of tree. In order to assess the amount of biomass in harvested and unmanaged Beech stands, two compartments (511 and 514) of Safaroodchr('39')s forest were selected. A plot of 6.25 hectare from e...
it is difficult to prevent accidents in the transport of hazardous goods, so the development of strategies for managing crisis situations and the optimization of action plans are important. the crisis situation is a continuous event in time when its evolution is unpredictable because it depends on a whole of complex factors resulting from the environment of the crisis. decision making in crisis...
The greening of economic and industrial activities requires that new relationships be formed between private actors who often never met before on the business or policy arenas. To initiate and give direction to the sustainability transition, public actors may choose to become involved in partnerships for policy implementation, next to industrial prime movers. After having catalyzed the process,...
Germany is in the process of transforming its system of electricity generation and distribution. Th e transformation process was advanced by a number of civil society actors keen on dismantling the old centralised, undemocratic, environmentally unsound and unhealthy system, and replacing it with a new one, closer to the people, decentralised and using renewable energies. One type of transformat...
