… there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the …
… weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined. Two breeds were included in the study, Swedish Red cows (SRB) and Swedish Holsteins (SH). This study was part of a larger …

… a distinct trend with increasing symptom development with increasing conidia concentration while the dry weight matter result did not indicate a similar distinct trend. The bioassay gives a relatively quick result and is easy to execute. For a clearer result, more plants per …
what are the soil requirements”
… hypotheses were that the soils would be acidic and highly weathered with low concentrations of plant available nutrients. Soils on lower altitudes were hypothesized to be less acidic and have higher concentration of nutrients. The soil description was expected to result in a …
En fallstudie av ett antal klasslärares syn på begreppetarbetsminne och arbetsminnesträning
… teachers in my study term difficulties that can arise for students as concentration difficulties, which according to previous research can count towards deficiencies in working memory. All of the respondents in this study believe that it is mostly special education teacher who …

… other than iron oxides are apatite, monazite and xenotime. The relative concentration of the REE-bearing phases differs from the other apatite-iron oxide mineralizations in the area, for example Grängesberg, by a higher concentration of xenotime and lower contents of allanite.
… were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables. Land use and especially intensive forestry and short distances of the water flow are suggested as possible …
… net used to move the larva, since it was in contact with all the substances concentrations. The standard deviations from the ellipsometry tests are very high, most likely due to uneven adsorption of the substances to the surface. With more tests and measurements, more accurate …

Utredning av hur metallbelastningen varierat över tid med hjälp av sediment som ett naturligt historiearkiv
… as a natural archive of historical metal inputs to the pond. I found that the concentration of lead, copper, zinc and nickel were elevated in comparison to background levels in sediment. Elevated concentrations were found in the deep layer of the sediment core, 14-20 cm with an …
