Calcium transporting ATPases in plant cells.

Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol

Handledning av kandidat- och magisteruppsatser.

Difficulties had been identified with regard to bachelor and master theses. The quality varied too much, as did supervision. The report discusses possible ways of improving the situations,looking at other departments at Lund University, as well as the Copenhagen Business School. The report suggests some measures for improving the process as well as for supporting supervisors.

Towards climate-responsible peatlands management

In the early 1970’s, about 80 ha of rich fen, meadows and wet forest on the margins of the largeand pristine raised bog ‘Komosse’ in Southern Sweden were drained by ditches to promote spruce(Picea abies) growth and forestry production. Draining had a dramatic impact on forest productionon the nutrient-rich peaty soils downhill from the ditches. In 40 years, most of the meadows andfens had turned i

Pheromones

Pheromones are chemical signals, that is, carriers of information between individuals within a species. Pheromones induce a physiological or behavioral response in the receiving individual, and often play a crucial role in mate finding and other interactions among animals. Most pheromone research has been done with insects, and in particular with species regarded as pests. For these, application o

Numerical study of thermo-acoustic waves generation by a swirling flame using a new approach based on large eddy simulation

The new challenge of the Gas Turbine industry is to develop new technologies for meeting electricity demand growth and reducing harmful emissions. Thus, a better understanding of the combustion phenomenon and an improvement in simulation capabilities are needed. In this paper, we present a new technique that is computationally efficient, for capturing the thermo-acoustic waves in low Mach number c

Kinetic Characterization of dUTPase from Escherichia coli

The enzyme dUTPase catalyzes the hydrolysis of dUTP to dUMP and pyrophosphate, thereby preventing a deleterious incorporation of uracil into DNA. The best known dUTPase is that from Escherichia coli, which, like the human enzyme, consists of three identical subunits. In the present work, the catalytic properties of the E. coli dUTPase were investigated in the pH range 5-11. The enzyme was found to
