GreenCharge : demotest i fält med elbuss
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- GreenCharge Sydost är en sammanslutning av regionförbund, kommuner, landsting och företag medett övergripande syfte att främja införandet av elfordon i främst sydöstra Sverige. Blekinge TekniskaHögskola är huvudman för projektet med ansvar för att driva forskningen, och Miljöfordon Syd attdriva den operativa projektledningen avseende demonstrationer och samverkan med intressenter.Under 2013 gjorde forskningen inom GreenCharge en beräkningsstudie som påvisade att elbussar urett livscykelperspektiv har mycket mindre utsläpp än dagens dieselbussar och totalkostnaden skullekunna bli 25 % lägre över en 8-års period i Karlskrona på linje 1 och 7, 21 % i Jönköping på linje 1och 3, samt 17 % i Sundsvall på linje 2 och 4. Detta gäller under antagande att bussen drivs med nygrön el, att realränteökningen blir 1 % per år samt att energi-pristrender sedan 10 år tillbaka fortsättergälla framöver.. Beräkningsstudien antog också efter simuleringar utifrån befintliga linjer och aktuellavärden från busstillverkare en energianvändning på 1,04 kWh/km för eldrift.

- The Swedish personal assistance system, facilitated through Swedish legislation (known as the LSS), allows children with profound intellectual and multiple disabilities (PIMD) to receive subsidized personal assistance. This assistance may be either a hired professional from outside the family or a parent paid as a personal assistant. The type of personal assistant can impact activity selection. As noted by bio-ecological systems theory, participation in "systems" beyond the household is important for a child's cognitive and social development, including the development of children with disabilities. The authors explored whether children's personal assistant type (i.e., external or parental) is related to their presence in socially integrative activities (SIAs) versus non-socially integrative activities (NSIAs). The relationship between children's activity engagement and their personal assistant type was examined via a descriptive, comparative study based on a questionnaire. Sixty families answered, providing quantitative data about personal assistance type across 56 common family activities. Children's external assistants showed a greater presence in SIAs than children's parental assistants, who showed a greater presence in NSIAs. The level of activity engagement between personal assistant type, however, had a less direct relationship. In accordance with bio-ecological systems theory, activity selection can influence the child's cognitive and social development. Ultimately, this study suggests that external assistants partake in more SIAs than parental assistants, likely as a function of providing respite for families. This respite stems from the LSS's implicit role for external personal assistants to also serve as relief for parents. In turn, by facilitating exposure to broader systems, these external assistants can play a critical role in children's social and cognitive development.

Overeating saturated fat promotes fatty liver and ceramides compared to polyunsaturated fat : a randomized trial
- 2019

Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: Saturated fat (SFA) versus polyunsaturated fat (PUFA) may promote non-alcoholic fatty liver disease (NAFLD) by yet unclear mechanisms.OBJECTIVE: To investigate if overeating SFA- and PUFA-enriched diets lead to differential liver fat accumulation in overweight and obese humans.DESIGN: Double-blind randomized trial (LIPOGAIN-2). Overfeeding SFA vs PUFA for 8 weeks, followed by 4 weeks of caloric restriction.SETTING: General community.Participants: n=61 overweight or obese men and women.INTERVENTION: Muffins high in either palm (SFA)- or sunflower oil (PUFA) were added to the habitual diet.MAIN OUTCOME MEASURE: Lean tissue mass (not reported here). Secondary and exploratory outcomes included liver and ectopic fat depots.RESULTS: By design, body weight gain was similar in SFA (2.31±1.38 kg) and PUFA (2.01±1.90 kg) groups, P=0.50. SFA markedly induced liver fat content (50% relative increase) along with liver enzymes and atherogenic serum lipids. In contrast, despite similar weight gain, PUFA did not increase liver fat or liver enzymes or cause any adverse effects on blood lipids. SFA had no differential effect on the accumulation of visceral fat, pancreas fat or total body fat compared with PUFA. SFA consistently increased, while PUFA reduced circulating ceramides; changes that were moderately associated with liver fat changes and proposed markers of hepatic lipogenesis. The adverse metabolic effects of SFA were reversed by calorie restriction.CONCLUSIONS: Saturated fat markedly induces liver fat and serum ceramides whereas dietary polyunsaturated fat prevent liver fat accumulation, reduce ceramides and hyperlipidemia during excess energy intake and weight gain in overweight individuals.
