21. Numerical modelling of geomaterials at failure
Sammanfattning : Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. LÄS MER
22. Lignocellulose Degradation by Soil Micro-organisms
Sammanfattning : Lignocellulosic biomass is a sustainable resource with abundant reserves. Compared to petroleum ‐ based products, the biomass ‐ derived polymers and chemicals give better environmental profiles. A lot of research interest is focused on understanding the lignocellulose structures. LÄS MER
23. Soil microbial diversity in agriculture : Responses to land-use and extreme weather events
Sammanfattning : Land-use intensification of agricultural soils and increased occurrence and intensity of extreme weather events like drought periods are two of the main threats responsible for soil biodiversity declines. These changes in soil biodiversity can alter ecosystem functions performed especially by soil microbial communities that could further contribute to those threats. LÄS MER
24. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials
Sammanfattning : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. LÄS MER
25. Characteristics of BVOC emissions from a Swedish boreal forest : Using chambers to capture biogenic volatile organic compounds (BVOCs) from trees and forest floor
Sammanfattning : Plant-emitted biogenic volatile organic compounds (BVOCs) are a large group of hydrocarbons released by plant leaves, bark, flowers and fruits into the atmosphere and from plant roots into the soil. BVOCs have important physiological and ecological functions, such as mediating within-plant and plant-plant communication, defense against herbivores attack, protection against heat or other oxidative stress, attracting pollinators etc. LÄS MER
