Innovativa åtgärdsförslag för renovering av byggnadsskal och installationer
- 2011
-
Rapport (refereegranskat)abstract
- I rapporten presenteras resultat från en del av Milparena projekt som rör åtgärder på byggnadsskalet och installationssystemen som har gjorts för att öka energieffektiviteten i byggnaden. Dels presenteras ett antal pilotprojekt och de åtgärder som har utförts i dessa projekt. Ett antal metoder för att tilläggsisolera, byta fönster och lufttäta klimatskalet presenteras. En renovering kan innebära förändrade tryck- och fuktförhållanden som kan påverka såväl värmebehovet som byggnadskonstruktionens beständighet och innemiljön i byggnaden. I rapporten presenteras därför ett systematiskt sätt, hur man undviker eventuella risker för oönskade konsekvenser genom att göra undersökningar av byggnadernas tekniska status före renovering, simuleringar av hygro-termiska förhållandena för olika alternativa renovering metoder, uppföljning och kontroll av resultaten i bygg- och bruksfasen. I rapporten presenteras även dokumentation av befintliga och utveckling av innovativa värmeåtervinningssystem för miljonprogrambyggnadernas typiska ventilationssystem, en systematisk genomgång av befintliga och utveckling av nya värmesystem samt varmvattensystem. Den senaste tidens utveckling av styr och mätsystem ger helt andra möjligheter till återkoppling än de som fanns när miljonprogrammet byggdes. Inom projektet har därför också en systematisk genomgång gjorts av metoder att minska värmebehovet genom förbättrad mätning och driftsövervakning.

- Among the thirteen human aquaporins (AQP0-12), the primary structure of AQP8 is unique. By sequence alignment it is evident that mammalian AQP8s form a separate subfamily distinct from the other mammalian aquaporins. The constriction region of the pore determining the solute specificity deviates in AQP8 making it permeable to both ammonia and H(2)O(2) in addition to water. To better understand the selectivity and gating mechanism of aquaporins, high-resolution structures are necessary. So far, the structure of one human aquaporin (HsAQP5) has been solved at atomic resolution. For mammalian aquaporins in general, high-resolution structures are only available for those belonging to the water-specific subfamily (including HsAQP5). Thus, it is of interest to solve structures of other aquaporin subfamily members with different solute specificities. To achieve this the aquaporins need to be overexpressed heterologously and purified. Here we use the methylotrophic yeast Pichia pastoris as a host for the overexpression. A wide screen of different detergents and detergent-lipid combinations resulted in the solubilization of functional human AQP8 protein and in well-ordered 2D crystals. It also became evident that removal of amino acids constituting affinity tags was crucial to achieve highly ordered 2D crystals diffracting to 3Å.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To explore chimney sweeping work tasks, chimney sweeps’ use of protective equipment, and type of fuel used by clients, over time. Further, to assess work-relatedness of current eye and airway symptoms. Methods: In a cross-sectional study in 2011, male Swedish chimney sweeps (n = 483; age 21–69 years) answered a questionnaire about their occupational history and eye and airway symptoms. Results: Between 1960 and 2010, black-soot-sweeping in private homes was the major task, although it decreased during the time period, for chimney sweeps. Between 1975 and 2010, the use of petroleum oil decreased, whereas the use of pellets and wood increased. Also, the use of gloves and masks increased significantly. Black-soot-sweeping in industry was associated with work-related eye symptoms (prevalence odds ratio POR = 3.76, 95% CI: 1.72–8.24, for every 10% increment of working time, adjusted for age and tobacco smoking). Chimney sweeps also had slightly higher prevalence of cough with increasing black-soot-sweeping (POR = 1.06, 95% CI: 0.99–1.13 for every 10% increment, further adjusted for the use of mask), and the association was more pronounced, although nonsignificant, for black-soot-sweeping in industry (adjusted POR = 1.26, 95% CI: 0.98–1.61). Conclusions: Chimney sweeping tasks and use of protective equipment as well as type of fuel used by the clients changed significantly over the last 35 years, which may have changed chimney sweeps’ exposure to soot. Still, chimney sweeps in Sweden have black-soot-sweeping-related eye and airway symptoms.

Tidskriftsartikel (refereegranskat)abstract
- Since the 1990s, a new model for market control organized through tripartite standards regimes (TSR), has expanded globally and affected most market exchanges through standard-setting, accreditation, and certification. This article investigates business-consumer relations under this regime, with a specific focus on the functions of accreditation and certification. In our case study of Sweden, a new picture of consumer protection under late capitalism evolves. Seeing it as a form of neoliberalization, the article uncovers a transition between two regimes of control; from one built on a potential conflict between consumer and business interests, to one based on the assumption that business interests are beneficial for all parties. Although business interest was formulated as pleasing the consumer-or the customer-by both certification firms and the Swedish Accreditation Authority, in practice consumer interest as something worth protecting was made abstract in the era of the TSR.

Ulriksdals slott under 350 år
- 1995
-
Rapport (populärvet., debatt m.m.)abstract
- Studierna har utgått från Ulriksdals slott, uppfört av Jacob De la Gardie för 350 år sedan. Som kungligt slott har Ulriksdal genomgått ombyggnader under 1600 - och 1700-talet, men präglas idag mest av Karl XVs omfattande omdaning på 1850-talet och Gustav VI Adolfs lika genomgripande förändringar på 1920-talet.Slottet har bjudit på rika studiemöjligheter av stilideal, planlösning, interiörgestaltning, snickerikultur och stormtekniska system från hela 350-årsperioden. Genom noggranna uppmätningar och inventeringar på plats kopplade till arkivstudier har slottets komplicerade förändringshistoria kunnat analyseras,

Do men with excessive alcohol consumption and social stability have an addictive personality?

Tidskriftsartikel (refereegranskat)abstract
- The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n = 100) in comparison to a population-based control group (n = 131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality".
