1. Nitrous oxide emission from soil : On extrapolation from soil environmental factors
Abstract : Nitrous oxide(N20) is a natural component of the atmosphere which contributes both to the greenhouse effect and to the destruction of stratospheric ozone. National as well as global inventories indicate thatboth natural and anthropogenic emissions from terrestrial ecosystems constitute a large fraction of the annual loading of N20 on the atmosphere.

3. Excavation in moraine and dense non-cohesive soil : Numerical analysis of soil behavior
Abstract : Excavation and moving of soil are common civil work tasks connected to the construction of buildings, roads and railways. In construction projects large amounts of soil have to be handled with different machines, tools and working methods. Soils are more or less difficult to excavate depending on their properties.

Abstract : Addition of fertiliser nitrogen (N) in crop production increases yields and protein contents, but all is not taken up by the crop. Instead, some of the N is lost to air and waters, contributing e.g. to climate change, stratospheric ozone depletion, eutrophication and acidification. READ MORE
