Popular Abstract in Swedish Kemisk vittring har en avgörande betydelse för hur näringsämnen frigörs, ansamlas och kan utnyttjas i mark/växtsystemet. Vittringshastigheten har därför stor betydelse för hur skogs- och jordbrukare kan optimera skogsskötseln och skördeuttaget, inom ramen för ett uthålligt skogsbruk. I avhandlingen studeras vittring av epidot och lermineral för att vidareutveckla den geChemical weathering is one of the most important processes supporting life on Earth. Chemical weathering continuously contributes macronutrients and micronutrients to the soil solution. These recycling, essential elements are used as building blocks for all organic living matter. Chemical weathering is a vital factor in the analysis and understanding of a large number of important environmental is

Plasma lipids and lipoproteins were studied in 26 nonobese diabetic patients, either newly diagnosed or unsatisfactorily controlled by oral antidiabetic treatment. Measurements were performed before and 3-4 mo after the institution of insulin treatment. In a subgroup of seven patients, the activities of lipoprotein lipase (LPL) and hepatic lipase (HL) in postheparin plasma and the elimination rate

Popular Abstract in Swedish Våtmarker är en naturtyp som man finner i övergångszoner mellan land och vatten. Idag talas det mycket om våtmarkers positiva natur- och miljövärden i avrinningsområden i det moderna jordbrukslandskapet. Våtmarker ger omväxling i landskapet och är viktiga biotoper för växter och djur. I våtmarker ansamlas mycket dött växtmaterial och tillsammans med en god tillgång på vIn this thesis, I have studied nitrogen turnover processes in watermeadows. A watermeadow is a wetland where water infiltrates through the soil of a grassland field. It is hypothesized that infiltration of water through the soil matrix promotes nutrient transformations compared to surface flow of water, by increasing the contact between water, nutrients, soil organic matter and bacteria. I have st

We study the problem of clustering fingerprints with at most p missing values (CMV (p) for short) naturally arising in oligonucleotide fingerprinting, which is an efficient method for characterizing DNA clone libraries.We show that already CMV(2) is NP-hard. We also show that a greedy algorithm yields a min(1 + ln n, 2+pln l) approximation for CMV(p), and can be implemented to run in O(nl2p) time.

The aim of this study was to describe social participation expressed as accomplished ordinary activities, health-related quality of life (HRQoL) and life satisfaction (LS), among elderly men and women with osteoporosis-related fractures with and without pain, compared to non-fractured controls. The study was a population-based case–control study conducted at a university hospital, including 408 su

The present study demonstrates the use of a simple and versatile melt-compounding route to prepare NaClO4-containing poly(ethylene oxide) PEO/clay nanocomposites combining excellent mechanical properties with a competitive level of the ionic conductivity. The nanostructure and the resulting thermal, mechanical and conductive properties of the salt-containing PEO/clay nanocomposites were found to b

Growth hormone deficiency (GHD) is associated with decreased bone mineral density (BMD). Low BMD is correlated to increased fracture risk. There are no studies on fracture risk in GHD patients on GH therapy and no studies on BMD in adults with childhood onset (CO) craniopharyngioma (CP) on GH therapy. We have shown a doubled fracture incidence in CO GHD women and decreased incidence of fractures i

We present a brief account of the most salient properties of vortices in dilute atomic Fermi superfluids near a Feshbach resonance.

The aims of this study were to evaluate the oral health status and nutritional status in a group of geriatric rehabilitation patients, and to analyse the relationship between these two parameters. Nurses at the ward performed structured assessments of oral and nutritional status using the Revised Oral Assessment Guide and the Subjective Global Assessment form in 223 newly admitted patients. Most o

In a previous report, a large regional variation was reported in total mortality and mortality rate from ischaemic heart disease (IHD) in mid-Sweden. In this report, IHD prevalence and risk factor data are presented. A postal questionnaire was sent out to a random sample of men aged 45-64 years in each of 40 communities. 14,675 men (88%) responded. Based on a validity study, IHD cases were defined

I föreliggande rapport redovisas en studie där en ny provningsmetod utarbetats för att prova alkalibeständigheten hos vattenavvisande preparat för fasadimpregnering.

An Fmoc-protected δ-sugar amino acid, prepared by oxidation of a glucosamine derivative, was coupled to three different tripeptide tert-butyl esters (H-Tyr-Tyr-Tyr-OtBu, H-Tyr-Glu(OBzl)-Tyr-OtBu and H-Tyr-Arg(Mtr)-Tyr-OtBu) and the resulting sugar amino acid/amino acid hybrids were transformed into dimers that were subsequently cyclized to give three C2-symmetric macrocycles. The macrocycles were

Hepatitis C virus (HCV) belongs to the Hepacivirus genus in the Flaviviridae family. Among the least known viral proteins in this family is the nonstructural protein NS4B, which has been suggested to be a part of the replication complex. Hydrophobicity plots indicate a common profile among the NS4B proteins from different members of the Flaviviridae family, suggesting a common function. In order t

Mycobacterium tuberculosis complex strains cultured in Denmark have been analyzed by IS6110 restriction fragment length polymorphism (RFLP) on a routine basis from 1992 and onwards. Due to the influx of immigrants with tuberculosis, the number of strains harboring only one to five copies of IS6110 has increased steadily. Since the discriminatory power of IS6110 fingerprinting for such strains is p
