… that countries with injecting drug users should introduce the so-called needle exchange programs (NEP) to curb the spread of infection by blood-borne diseases. In Sweden the first NEP started 1985 in Lund, but the program was extremely controversial in a country with such a …
This study has analyzed particel size distribution and needle content in chipped logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped logging residuals from pure softwood …

… The fire effects were estimated in the field inventory as percentage loss of needles. Also variables which describe the stand structure in the plots (height, tree composition, basal area) were measured. In the field, the border of each burned area was also mapped with GPS …
… a 2 mm mesh size. The fine material contained soil particles and spruce needles. Thecoarse material contained twigs and pine needles. The 137Cs activity was always higher in thefine material samples than in the coarse samples. The activity increased by depth. Ants, thecoarse top …
… seedlings, a wide tree diameter range) and a proportionally high amount of needle dominated litter on the ground. The negative correspondence with tree age may be related to a reduced production of needle biomass in older trees, which may reduce nutrient availability for S …
… from delimbed sawlogs are not recovered and only long top (with branches and needles still attached) is hauled the landing site. To optimize income from the LT-method knowledge about the share of recovery of respectively saw logs and fuel wood at different stand conditions and …

… are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce …
Skogen är en förnyelsebar energikälla som möjliggör för ett minskat beroende av fossila bränslen. Ur ett politiskt perspektiv minskar såväl klimatpåverkan som beroendet av importerad energi från oroliga delar av världen genom att ta tillvara skogsbränsle lokalt. I Sverige är …
… wood) and thinning with cutting of round wood and long tops (incl. branches/needles). Two stands in Medelpad, Sweden were the objects for the thinning study and data acquisition. The study shows that lodgepole pine is a suitable species if biomass energy is to be produced. There …
… fraction and 10-40 times higher in the remaining fractions (bark, branches and needles). The chloride concentration showed no relation to the amount of deposited chloride. Instead there was a correlation between concentration and amount of precipitation, measured as throughfall …
… New functions have been developed that estimate the biomass of branches and needles from stand variables. The new functions have been applied on a selection from Sveaskog´s inventory together with a model that estimates the amount of fuel collected in different terrain types in …
… a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using …
… the objects, ICP/MS-DRC was used to obtain content of boron in spruce and pine needles, pH was determined and density on the objects were determined by fixed volume cylinder sampling. 13 objects were investigated in this study and two of these were control objects where no …

… ones. Containerised seedlings had larger height-growth and greener needles than bare-rooted seedlings after the first growing season, which indicates that containerised seedlings was able to establish faster in its new environment after planting than bare-rooted seedlings. The …
… fine-wire electrodes were inserted bilateral into TrA and RA with an injection needle with guidance from an ultrasound. EMG was recorded during the middle second (while the subjects were asked to withhold the final position) and data was normalized to maximal voluntary …
