1. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status
Sammanfattning : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. LÄS MER
2. Reassembling the Environmental Archives of the Cold War : Perspectives from the Russian North
Sammanfattning : To what extent the environmental history of the Arctic can move beyond thedivide between Indigenous peoples and newcomers or vernacular and academicways of knowing?

3. On the mortality of patients treated with dental implants: Association to age, degree of tooth loss, and treatment modality
Sammanfattning : Rehabilitation of partially or completely edentulous patients with implant-supported prostheses is a common treatment in dentistry. Clinical studies evaluating this type of treatment have largely focused on technical and biolog-ical complications. LÄS MER
4. Characterization of Aeromonas, Enterobacteriaceae, Pseudomonas, Bacillus and Lactobacillus spontaneously growing to high numbers in milk, minced meat, fish or cheese
Sammanfattning : The spoilage flora of refrigerated raw and pasteurized milk was classified and identified by numerical phenotypic analysis. Isolations of bacteria were made at a defined spoilage stage, when the total aerobic count was 106-107 cfu per ml. The secondary flora of ripened Swedish and Norwegian cheeses was investigated by numerical analysis. LÄS MER
