Comparison of soil fungal/bacterial ratios in a pH gradient using physiological and PLFA-based techniques

We have compared the total microbial biomass and the fungal/bacterial ratio estimated using substrate-induced respiration (SIR) in combination with the selective inhibition technique and using the phospholipid fatty acid (PLFA) technique in a pH gradient (3.0-7.2) consisting of 53 mature broad-leaved forest soils. A fungal/bacterial biomass index using the PLFA technique was calculated using the P

Cost-Benefit Analysis of Separation Distances - a utility-based approach to risk management decision-making

Decision-making in risk management reflects a normative choice of approach. This dissertation is concerned with the possibility of putting the decision in focus by employing an optimum decision criterion within a utility-based approach. The dissertation describes a cost-benefit analysis of separation distance, a risk-reducing measure used in land use planning in the vicinity of hazardous installat

From the meaning of embodiment to the embodiment of meaning

Unlike in much of the contemporary discussion of embodiment, phenomenology is really involved with the body as a kind of meaning appearing to consciousness; and it does not only attend to the body of the biological organism, but also to the kind of organism-independent artefacts which are required by some sign systems. Because it is concerned with meaning, phenomenology is akin to semiotics. From

Growth and optical properties of strained GaAs-GaxIn1-xP core-shell nanowires

We have synthesized GaAs-GaxIn1-xP (0.34 < x < 0.69) core-shell nanowires by metal-organic vapor phase epitaxy. The nanowire core was grown Au-catalyzed at a low temperature (450 degrees C) where only little growth takes place on the side facets. The shell was added by growth at a higher temperature (600 degrees C), where the kinetic hindrance of the side facet growth is overcome. Photoluminescenc

Control Systems with Friction

Popular Abstract in Swedish Avhandlingen behandlar reglertekniska problem orsakade av friktion. Tre aspekter behandlas: modellering, analys av självsvängningar orsakade av friktion och friktionskompensering. En ny relativt enkel matematisk modell för friktion presenteras och studeras. Modellen kan återge experimentella observationer av friktionsbeteende. Matematiska verktyg för att bestämma självsFriction-related problems are frequently encountered in control systems. This thesis treats three aspects of such problems: modeling, analysis, and friction compensation. A new dynamic friction model is presented and investigated. The model is described by a first order nonlinear differential equation with a reasonable number of parameters, yet it captures most of the experimentally observed frict

An investigation of pairing correlations in diabatic configurations at high spin and large deformation: applications to the description of SD bands in Eu-143

The HFB cranked shell model is applied in an investigation of the selfconsistent pairing properties of the superdeformed (SD) bands in Eu-143. Results from a fully pairing and deformation selfconsistent mesh calculation of the properties of the most intense SD band in 143Eu are presented, as well as pairing selfconsistent calculations done at a fixed deformation close to the SD minimum for an exci

Glycemia and insulinemia in healthy subjects after lactose-equivalent meals of milk and other food proteins: the role of plasma amino acids and incretins1,2,3

Background: Milk products deviate from other carbohydrate-containing foods in that they produce high insulin responses, despite their low GI. The insulinotropic mechanism of milk has not been elucidated. Objective: The objective was to evaluate the effect of common dietary sources of animal or vegetable proteins on concentrations of postprandial blood glucose, insulin, amino acids, and incretin

Compaction of forest soil by logging machinery favours occurrence of prokaryotes

Soil compaction caused by passage of logging machinery reduces the soil air capacity. Changed abiotic factors might induce a change in the soil microbial community and favour organisms capable of tolerating anoxic conditions. The goals of this study were to resolve differences between soil microbial communities obtained from wheel-tracks (i.e. compacted) and their adjacent undisturbed sites, and t

Proteome analysis of cultured fibroblasts from type 1 diabetic patients and normal subjects

Context: Protein profiling of diabetic tissues could provide useful biomarkers for early diagnosis, therapeutic targets, and disease response markers. Cultured fibroblasts are a useful in vitro model for proteome analysis and study of the molecular mechanisms involved in diabetes. Objective: The objective of the study was to isolate and characterize the proteins of cultured fibroblasts, obtained b

Dense resistivity and induced polarization profiling for a landfill restoration project at Harlov, Southern Sweden

A resistivity and time-domain induced polarization (IP) survey was conducted at a landfill Site under restoration at Harlov in Southern Sweden. The covering of the landfill had begun some years ago, without keeping precise records of the work done, as is usual in such procedures. The survey was conducted in two steps, on two adjacent areas. First, a number of geoelectrical sections were made on a

Holocene climate variability at multidecadal time scales detected by sedimentological indicators in a shelf core NW off Iceland

A Holocene sediment record is presented from the Djupall trough, situated on the inner shelf northwest of Iceland. The paleoclimatic development has been interpreted on the basis of mass accumulation rate, carbonate content, mean grain size, sediment petrology and 29 radiocarbon dates. The results demonstrate in the early Holocene (10,000-8000 cal year BP) high sediment accumulation rates attribut

How technology is reshaping the practice of nongynecologic cytology - Frontiers of cytology symposium

To pay tribute to the Founders of Acta Cytologica, this Golden Anniversary symposium on nongynecologic cytology revives the written symposium style of the 1950s. Participants from countries throughout the world were asked how new technologies are currently applied in their laboratories and whether future advances and challenges can be predicted. The specific questions and the participants' answers
