Heterologous genes for xylose utilization were introduced into an industrial Saccharomyces cerevisiae, strain A, with the aim of producing fuel ethanol from lignocellulosic feedstocks. Two transformants, A4 and A6, were evaluated by comparing the performance in 4-l anaerobic batch cultivations to both the parent strain and a laboratory xylose-utilizing strain: S. cerevisiae TMB 3001. During growth
Popular Abstract in Swedish Hematopoes är den process under vilken alla röda och vita blodceller i kroppen bildas. Denna process sker kontinuerligt i benmärgen och förser kroppen med blodceller under hela livet. I benmärgen finns en viss typ av omogna celler sk stamceller som alla olika typer av blodceller bildas ifrån. Genom att stamceller gradvis mognar så bildas mogna blodceller som transporterThe Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. The ojective of this thesis was to investigate the role of WT1 during human hematopoiesis and leukemia. To ga
Has the 'Swedish model' forced Sweden into stagnating economic growth? And has this caused Sweden to lag behind other comparable OECD-countries from the 1970s and onwards, i.e. since Sweden chose a welfare path different from many other countries? This has been the subject of a more than twenty year long controversy between Walter Korpi, professor of sociology and social policy, and leading Swedis
Pre-treatment of sisal pulp prior to its anaerobic digestion was investigated using an activated sludge mixed culture under aerobic conditions in batch bioreactors at 37 degrees C. The progression of aerobic pre-treatment of the residue in relation to the activities of some extracellular hydrolytic enzymes in the slurry was monitored. The highest activity of hydrolytic enzymes was obtained at 9 h
Responses to isotonic quick releases of rabbit urinary bladder strips and rat portal veins activated by AC-stimulation and K+-high medium were studied. The AC stimulation was adjusted to give the same tension as th K+-contractures. Releases were performed at peak of the contractions (which was attained after 1.5-4.5 s AC-stimulation or 2-3 min in K+-high solution). The length response consisted of
This chapter deals with the depictions of movement of violence in key narratives in Roman historiography.
First results from a study into the abundance trends of oxygen in the Galactic thin and thick disks are presented. Oxygen abundances for 63nearby F and G dwarf stars, based on very high resolution spectra (R∼215 000) and high signal-to-noise (S/N>400) of the faint forbidden oxygen line at 6300Å, have been determined. Our findings can be summarized as follows: 1) at [Fe/H]<0 the oxygen trends in th
Popular Abstract in Swedish Större delen av den kunskap vi har om Universum får vi genom att undersöka det ljus som olika kosmiska objekt sänder ut. Det synliga ljuset från en stjärna består av kontinuerlig strålning (Planckstrålning) vars färg ger ett mått på temperaturen av stjärnans yta på samma sätt som färgen hos upphettade metallföremål. Vid en närmare undersökning av stjärnans spektrum kan The new generation of high resolution astronomical instruments such as the Hubble Space Telescope (HST) or the Very Large Telescope (VLT) has renewed the demand for accurate atomic parameters like wavelengths, oscillator strengths and line profiles accompanied by reliable uncertainty estimates. Fourier transform spectroscopy has proven to be a powerful tool when measuring these parameters. In this
Occlusion is the most common reason for lowered recognition yield in free-flow license-plate reading systems. (Non-)occluded characters can readily be learned in separate neural networks but not together. Even a small proportion of occluded characters in the training set will already significantly reduce the overall recognition yield. This paper shows that a modular network can handle a realistic

Tetrapyrroles are synthesised through a single branched biosynthetic pathway. Heme and chlorophyll are synthesised from the common intermediate protoporphyrin IX at the heme-chlorophyll branch-point. Ferrochelatase catalyses the synthesis of heme by inserting Fe(II) into the protoporphyrin macro-cycle while magnesium chelatase, a three-subunit enzyme, catalyses the first unique step in chlorophyll
Popular Abstract in Swedish Malmö erbjuder speciellt goda möjligheter till epidemiologiska studier, därför att all sjukhusbunden vård erbjuds av ett enda sjukhus som dessutom i stort sett endast täcker Malmös egna behov. Därtill kommer att nu avlidne professor Folke Linell redan under 1950-talet insåg den stora betydelsen för sjukvårdens kvalitet av en omfattande obduktionsverksamhet. Under periodIn the present thesis incidence, survival, mortality, cure and prognosis in invasive breast cancer in Malmö was studied over a 30 year period. Validated data from the Cancer Registry and the Cause of Death Registry were used. In the process of validation systematical biases were identified in both registers. The incidence increased over time and was strongly related to increases in diagnostic acti
We investigating the role of anticipation and attention in a dynamic environment in a number of large scale simulations of an agent that tries to negotiate a number of gates that continuously open and close. In particular we have looked at learning mechanisms that can predict the future positions of the gates and control strategies that will allow the agent to pass through the gates unharmed. The
