Characteristics of Bioethanol Fuel Obtained From LignocelluloseI Biomass in Internal Combustion Reciprocating Engines With Spark- and Compressioignition
(Eesti Maaülikool, 2013)It can be claimed about the use of bioethanol produced on the basis of lignocellulose raw material under Estonian conditions that: 1. The amount of fuel produced from one hectare of natural grasslands is seven times ... -
Disturbance effects on boreal forest ecosystem carbon dynamics
(Eesti Maaülikool, 2013)Fire is the most prevalent form of stand-replacing natural disturbance in boreal forests. However, corresponding with increasing global resource demand, harvesting now affects millions of ha of boreal forest each year, yet ... -
Microsites and tree regeneration dynamics: prolonged storm effects in hemiboreal mixed forest
(Eesti Maaülikool, 2013)Windstorm, among the main natural disturbance agents in central and northern Europe, is found to have controversial effects on the direction of forest succession. Storm severity explains part of the contradiction, but the ... -
Precise hydrodynamic levelling using pressure gauges with application to improvement of the Estonian National Levelling Network
(Eesti Maaülikool, 2013)Levelling is a branch of surveying which is used to determine height differences with respect to benchmarks with known heights. Precise heights are important in many applications, e.g. in geodesy, engineering and oceanography. ... -
Understorey vegetation and factors affecting it in young deciduous forest plantations on former agricultural land
(Eesti Maaülikool, 2013)The establishment of forest plantations (including short-rotation forest plantations) is seen as one way to reemploy abandoned agricultural sites. The main goal of commercial forest plantations is the production of timber ...
