Over the years, various technologies have been utilized for Natural Organic Matter (NOM) removal with varying degrees of success. Conventional treatment methods comprising of coagulation, flocculation, sedimentation, or filtration are widely used to remove NOM. An alternative to these conventional methods is to use spiral wound membranes. These membranes tend to remove too much hardness whilst bei
BACKGROUND While there is ample evidence for health risks associated with heat and other extreme weather events today, little is known about the impact of weather patterns on population health in preindustrial societies.OBJECTIVETo investigate the impact of weather patterns on population health in Sweden before and during industrialization.METHODSWe obtained records of monthly mortality and of mon
How do donors reason and justify their choices when faced with dilemmas in a charitable context? In two studies, Swedish students were confronted with helping dilemmas based on the identifiable victim effect, the proportion dominance effect and the ingroup effect. Each dilemma consisted of two comparable charity projects and participants were asked to choose one project over the other. They were t

The neuronopathic forms of the human inherited metabolic disorder, Gaucher disease (GD), are characterized by severe neuronal loss, astrogliosis and microglial proliferation, but the cellular and molecular pathways causing these changes are not known. Recently, a mouse model of neuronopathic GD was generated in which glucocerebrosidase deficiency is limited to neural and glial progenitor cells. We
Genital high-risk human papillomaviruses (HPVs) cause cervical cancer and are also found in a small proportion of nonmelanoma skin cancers (NMSCs). We used cancer registry linkages to follow the 856,000 serum donors included in the Southern Sweden Microbiology Biobank or the Janus Biobank in Norway, for incident skin cancers occurring up to 30 years after serum donation. Serum samples taken before
The classic obligate pollination–seed consumption mutualism between yuccas and yucca moths has been thought to be mediated by chemical cues, but empirical data on pollinator attraction to host floral volatiles in this association have been lacking. Here we show that the scent from virgin flowers of the host Yucca glauca is sufficient to attract its obligate pollinator Tegeticula yuccasella in Y-tu
The text of the Skara Missal Compared to Other Liturgical Sources. A large number of printed sources have been consulted and compared with Skara Missal on a quntitative as well as qualitative basis; individual characteristics as well as the evident concordance with many identical readings have been noted and compiled. On the basis of comparisons of various paryers and prefaces it may first of all
Popular Abstract in Swedish Pyralidfjärilars reproduktionsekologi eller Med mitt mått mätt omåttligt mottlik sex Skadeinsekter Alla har väl någon gång haft besvär med inomhusskadeinsekter. Om inte, känner ni alldeles säkert någon som har haft det. Vem tycker inte att det är obehagligt att hitta larver och spinn i sina flingor på morgonen? När insekterna väl har fått sitt grepp om skafferiet, ärOlfactory cues play an important role in the reproduction of three pyralid moths, the Indian meal moth (Plodia interpunctella), the Mediterranean flour moth (Ephestia kuehniella) and the almond moth (E. cautella). Both males and females of P. interpunctella are capable of multiple matings. More energy is placed into the first mating by the male, as indicated by the larger spermatophore donated by
The major cytogenetic subgroup of lipomas is characterized by aberrations of chromosome segment 12q13-15, which recombines with a large number of other chromosomal regions. The gene HMGA2 is the main target in these aberrations. For some recurrent rearrangements, chimeric transcripts, including the 5' part of HMGA2, have been described. The 3' partners identified are LPP, LHFP, CMKOR1, and EBF. In
Mechanical properties and rate of ATP breakdown (JATP) have been determined in the chemically skinned guinea-pig taenia coli at 22 degrees C. The influence of varied [Ca2+], [Mg ATP] and muscle length were investigated. The shortening response after a step decrease in force (isotonic quick release) was highly curvilinear in the first 100-200 ms. This effect was shown to be a time-dependent respons
Popular Abstract in Swedish I avhandlingen redovisas undersökningar av näringsdynamiken hos fem olika lövträdsarter (ask, björk, bok, ek och lind) vilka jämförs med gran, som är ett mycket undersökt trädslag ur närings-synvinkel. Målsättningen med studierna var att klargöra de olika trädslagens näringstillstånd under likartade förhållanden, deras inverkan på och samspel med marken, samt deras näriThis thesis considers several important aspects of nutrient dynamics and allocation in adult stands of Swedish forest tree species (Quercus robur L., Tilia cordata Mill., Fraxinus excelsior L., Betula pendula Roth., Fagus sylvatica L. and Picea abies (L.) Karst) planted on the same soils. Differences between species in macro- (N, P, K, Ca, Mg, S), and micro- (B, Cu, Fe, Mn, Zn) nutrient levels in
Popular Abstract in Swedish Vad har jag gjort de senaste åren? Och varför? Det är det många som har undrat. Så stundtals även jag. Vad jag skriver nedan syftar inte till att förklara detta, utan är bara ämnat som en kort introduktion. Jag har de senaste åren jobbat med gener och proteiner från både växter och bakterier. Både gener och proteiner är väldigt små saker, men även den minsta lilla sak This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. The focus has been to establish where the metal and the porphyrin binds to the enzyme, and how they are pu
Background Epidemiological studies have, so far, identified factors associated with increased risk for incident or progressive OA, such as age, sex, heredity, obesity, and joint injury. There is, however, a paucity of long-term data that provide information on the nature of disease progression on either group or individual levels. Such information is needed for identification of study cohorts and
Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. The conversion of
Previous studies have reported variation in BRCA1 breast and ovarian cancer risks with mutation position, suggesting that mutations toward the 3' end of the gene are associated with lower ovarian cancer risks. We evaluated the evidence for genotype-phenotype correlations in 356 families with protein-truncating BRCA1 mutations. In contrast to previous reports, the ovarian:breast cancer ratio associ
The action of three matrix metalloproteinases (MMPs), 72- and 95-kDa gelatinases (MMP-2 and MMP-9) and PUMP (MMP-7), and a cysteine proteinase, cathepsin B, were investigated on aggrecan the major proteoglycan of cartilage. All the enzymes cleaved aggrecan although the activity of the 95-kDa gelatinase was very low. Specific cleavage sites were investigated following incubation with a purified agg
Background. Previous studies have shown high rates of psychosis among Afro-Caribbean immigrants to the UK and immigrants to the Netherlands. Rates of schizophrenia-like psychoses (SLP), i.e. schizophrenia or other non-affective psychosis, among the native-born and immigrant populations were assessed in Malm, the city in Sweden with the highest proportion of immigrants.Methods. All adult patients a
Human malignant infantile osteopetrosis (arOP; MIM 259700) is a genetically heterogenous autosomal recessive disorder of bone metabolism, which, if untreated, has a fatal outcome. Our group, as well as others, have recently identified mutations in the ATP6i (TCIRG1) gene, encoding the a3 subunit of the vacuolar proton pump, which mediates the acidification of the bone/osteoclast interface, are res
To study mechanical control of tissue differentiation, we designed a new version of the previously described bone conduction chamber. The bone conduction chamber consists of a cylindrical titanium chamber for implantation in the rat tibia. It has tissue ingrowth openings at one end, located subcortically, and the other end protrudes into the subcutis. The newly developed load chamber has a mobile
