Vilken föryngringsmetod ger bäst resultat på torra och friska marker, höst- eller vårplanering? : en jämförande studie utförd på uppdrag av Stora Enso Skog por Persson, Stefan

“…An equal distribution aimed at clear cut areas witch have been scarification with harrow and excavator. The clear cut areas should also have low site index. …”

Skogsdikningens historia på Kosta revir por Boley, Klara

“…Between 1952- 1958 the dynamite had a short breakthrough as a drainage method, before it was replaced by the excavator. A closer study has been made in Hampmossen in Kosta national forest region, that was drained in the 1930’s. …”

Grovkrossning av stubbar : en produktivitetsstudie por Bertilsson, Mattias

Problematizing productivity : exploring patterns of thought in the swedish national food strategy por Eriksson, Viktor

“…By analysing how the problems of environmental sustainability and productivity are addressed, the study aims to excavate unearthed ways of thinking. The findings show that environmental sustainability is assumed to be attained through increased and intensified production, hoping to substitute ‘unsustainable’ international produce with Swedish ‘sustainable’ produce on the world market. …”

Allometric Models for Estimating Carbon Fixation in Citrus Trees por Quinones, Ana, Martínez-Alcántara, Belén, Font, Antonio, Forner-Giner, María A., Legaz, Francisco, Primo-Millo, Eduardo, Iglesias, Domingo J.

“…We proposed quantifying the net primary production in different-aged citrus trees through the measurement of annual increases in the C content of the biomass of trees of different ages completely excavated. The measured net primary production in mature citrus was 27 kg C tree(-1) (1143 g C m(-2) yr(-1); 11.4 Mg C ha(-1) yr(-1)) with a similar behavior to that of different forests. …”

Development of a bioacoustic sensor for the early detection of Red Palm Weevil (Rhynchophorus ferrugineus Olivier) por Gutiérrez, Abelardo, Ruiz-Martínez, Vicente, Moltó, Enrique, Tapia, Gervasio, Téllez-Navarro, María M.

“…Bioacoustic sensors provide a good alternative for early detection of this pest because larvae activity is audible while they excavate tunnels to feed. This work describes the different stages for the development of an original electronic device based on acoustic sensors for early detection of Red Palm Weevil larvae in the interior of palms. …”

Implication of groundwater fluctuation on the seasonal salt dynamic in the Harran Plain, south-eastern Turkey por Cullu, M.A., Aydemir, M., Qadir, Manzoor, Almaca, A., Ozturkmen, A.R., Bilgic, A., Agca, N.

“…A study was carried out to investigate the effect of groundwater fluctuation on the seasonal salt dynamic in four widespread soil series in the Harran Plain with different natural drainage, south-eastern Turkey. Four profiles were excavated and soil samples were collected seasonally up to 100 cm depth with 10 cm intervals. …”
