Desferrioxamine-B (DFOB) is a bacterial trihydroxamate siderophore and probably the most studied to date. However, the manner in which DFOB adsorbs at mineral surfaces and promotes dissolution is still under discussion. Here we investigated the adsorption and dissolution reactions in the goethite-DFOB system using both in situ infrared spectroscopic and quantitative analytical methods. Experiments

STUDY DESIGN. Symptomatic patients were retrospectively analyzed and compared with a control group from an ongoing prospective and consecutive study. OBJECTIVES. To determine the presence and extent of epidural fibrosis in patients with and without recurrent sciatic pain after previous lumbar discectomy, contrast-enhanced magnetic resonance images were evaluated and correlated with surgical findin

Popular Abstract in Swedish Cancer är ett samlingsnamn på sjukdomar som kännetecknas av okontrollerad celltillväxt. I friskt tillstånd växer kroppens celler kontrollerat. Cancertillståndet startar när någon av dessa celler förändras så att tillväxten ökar. När tillväxten ökar så tilltar också celldelningen. Om ingen åtgärd vidtas kommer cancern till slut att slå ut funktionen hos det organ som denCancer is the collective name for diseases that have one thing in common ? uncontrolled cell growth. The increase in cancer cell proliferation eventually results in tumor formation and, in the worst case, metastatic spread to other organs. Common treatment modalities of cancer include chemotherapy and radiation therapy. However, these methods are associated with severe side effects as well as indu

Popular Abstract in Swedish Gående som mellanmänsklig handling Traska, spatsera, flanera, power-gå, ila, dra fötterna efter sig, ta en stärkande promenad eller bara vandra bort i tankarna för en kort stund. Att gå är en komplex handling som omfattar allt från upplevelsen av marken som vi går på till människorna vi möter. Både när vi är ute och går själva eller tillsammans med andra så förhåller vThere is a lack of attention toward the diversity in experiences of architecture that are expressed through walking. Through the application of autoethnography and critical perspectives of queer and feminist theory, this dissertation develops a method for investigating experiences of architecture in regard to the activity of walking. In addition, this thesis addresses the influence of form, materi

Popular Abstract in Swedish I avhandlingen presenteras ett matematiskt ramverk för analys av datagenomströmning i paket-baserade radionät som stör varandra. Tidigare forskning om prestanda i paketradionät täcker många olika system och aspekter. Tidigare publicerade arbeten har dock till stor del varit begränsade till fixa paketlängder. Ramverket som presenteras i avhandlingen tillåter detaljerad a

To avoid eutrofication and excessive algal bloms it is necessary to reduce the phosphorus contents in wastewater. Previous wastewater treatment systems often have a good process for phosphorus reduction but in general not the ability to recycle the material and phosphorus for further utilisation after its use in wastewater treatment. Polonite® is a material with large content of calciumoxide wh

While many species suffer from human activities, some like geese benefit and may show range expansions. In some cases geese (partially) gave up migration and started breeding at wintering and stopover grounds. Range expansion may be facilitated and accompanied by physiological changes, especially when associated with changes in migratory behaviour. Interspecific comparisons found that migratory te
