Cattle and goat grazing on the herbaceous cover of a lowered caatinga.
(In: INTERNATIONAL CONFERENCE ON GOATS, 4., 1987, Brasília, DF. Proceedings... Brasília, DF: EMBRAPA-DDT, 1987. v. 2, p. 1431. Resumo 184, 1987)
Conceptual design of biomass-fired cogeneration plant through a knowledge-based system
Industries such as sugar/ethanol and paper/pulp generate large amount of biomass as by-products that must be properly handled to avoid environmental damage. A synergetic alternative to address this issue is to use the ...
Allometric relations for biomass partitioning of Nothofagus antarctica trees of different crown classes growing in a site quality gradient
(Elsevier Science, 2010-03)
Data on tree biomass are essential for understanding the forest carbon cycle and plant adaptations to the environment. We determined biomass accumulation and allometric relationships in the partitioning of biomass between ...
Study of the mechanical and energetic properties of pellets produce from agricultural biomass of quinoa, beans, oat, cattail and wheat
(SpringerPaíses Bajos, 2017)
The lack of conventional fuels in rural areas in Peru drives people to burn agricultural wastes that are used as fuel. Burning these wastes produce a large amount of gaseous pollutants that harm the health of ...
Influence of fertilizer on coumarin content and biomass production in Mikania glomerata sprengel
Mikania glomerata Sprengel leaf extracts have been used in cough syrup formulations due to the presence of active coumarin derivatives. Yields of such natural compounds in cultivated plants can be affected by several ...
Differential root and shoot biomass recovery in wheat and barley with transient waterlogging during preflowering
Aims: Wheat and barley plants exposed to waterlogging reduced their growth, but the final impact on grain yield depends on the capacity of the plant to recover after stress. The aim of this study was to evaluate shoot and ...
Negative and positive interactions among plants: effect of competitors and litter on seedling emergence and growth of forest and grassland species
Living plant neighbours, but also their dead aboveground remains (i.e. litter), may individually exert negative or positive effects on plant recruitment. Although living plants and litter co-occur in most ecosystems, few ...
Biomass Refinery as a Renewable Complement to the Petroleum Refinery
(BERKELEY ELECTRONIC PRESS, 2010)
Biomass Refinery is a sequential of eleven thermochemical processes and one biological process with two initial basic treatments: prehydrolysis for lignocellulosics and low temperature conversion for biomass with medium-to-high ...
Biomass production and mineral element supply of selected useful tropical plants.
