This paper reports on a numerical study of the thermodynamic and basic combustion characteristics of oxy-fuel combustion in gas turbine related conditions using detailed chemical kinetic and thermodynamic calculations. The oxy-fuels considered are mixtures of CH4, O-2, CO2 and H2O, representing natural gas combustion under nitrogen free gas turbine conditions. The GRI Mech 3.0 chemical kinetic mec
This study reports increasing iron concentrations in rivers draining into the Baltic Sea. Given the decisive role of iron to the structure and biogeochemical function of aquatic ecosystems, this trend is likely one with far reaching consequences to the receiving system. What those consequences may be depends on the fate of the iron in estuarine mixing. We here assess the stability of riverine iron
Replicated, factorial mesocosm experiments were conducted across Europe to study the effects of nutrient enrichment and fish density on macrophytes and on periphyton chlorophyll a (chl-a) with regard to latitude. Periphyton chl-a densities and plant decline were significantly related to nutrient loading in all countries. Fish effects were significant in a few sites only, mostly because of their co
A Summary In a large cohort of elderly women followed for 10 years, we found that balance, gait speed, and self-reported history of fall independently predicted fracture. These clinical risk factors are easily evaluated and therefore advantageous in a clinical setting. They would improve fracture risk assessment and thereby also fracture prevention. Introduction The aim of this study was to identi
Popular Abstract in Swedish Chefskap och ledarskap hos sjuksköterskor i högre chefsbefattningar inom hälso- och sjukvården. I dagens hälso- och sjukvård har sjuksköterskor i chefsposition en förändrad och utökad roll, bland annat till följd av decentraliserade organisationer och utökade ansvarsområden. Utvecklingen av omvårdnaden kommer till en del att vara beroende av chefernas förmåga och skickThe aim of this thesis was to illuminate the management and leadership of nurse managers within Swedish health care organizations and to recognize influencing factors of importance for the nurse managers in exercising and developing their management. The interviewees were all active in their positions at the time of the interviews. The nurse managers served at top management levels in either execu
In a Northern country such as Sweden, energy use in the home may be reduced by 20% through changes in behaviour. However, little is known about how households respond to policy instruments encouraging such change or to what degree this in turn may affect the workload of women and men in such communities. The current study presents findings from interviews with 30 households in Sweden that particip

The health effects were measured by scales that assess mindfulness, health, positive and negative affects, life satisfaction and psychological wellbeing. The training period was 30 days and 234 persons participated in three randomly assigne
Karst är landskap och karakteristika som är viktiga både ur hydrologisk och geologisk synpunkt och som är utvecklade genom vattnets vittring av oftast karbonathaltiga stenar. Denna uppsats kartlägger världens karstområden, beskriver egenskaper av karst och karsthydrologi och strävar efter att definiera problem och möjligheter med vattenhantering i karstlandskap. Akvifärer i karst skiljer sig i månSummary: Water is, and will in the near future be even more, a key issue for the global development, and for issues concerning equal rigts for all mankind. Water is a necessity and a scarce resource in great parts of the world and it therefore exists a great need for development and management of the world’s waters. With fresh waters being increasingly accentuated for their importance in global de
De senaste 100 åren har den globala medeltemperaturen ökat i genomsnitt 0,74 grader, vilket medför stora effekter för såväl människor som djur och natur. En av de största konsekvenserna till den globala uppvärmningen är att den stigande havsnivån blir allt mer påtaglig världen över. Glaciärer och inlandsisar har börjat smälta allt mer, där avsmältningen medför en global ökning i havsnivån. HavsnivThe rising sea level is becoming more evident around the world as less as well as more developed countries are starting to fully comprehend the consequenses. It is also generally accepted that the sea level rise is accelerated by human-induced global warming. Glaciers and ice sheets are melting more and more, which together with temperature induced thermal expansion of the seas which leads to a gl

Background: Limited data exist on transcatheter aortic valve replacement (TAVR) outcomes in patients with bicuspid aortic valve (BAV) stenosis. This study compared TAVR outcomes in BAV versus tricuspid aortic stenosis. Methods: This observational study included all patients who underwent TAVR in Sweden from 2016 to 2022, excluding those with pure aortic insufficiency and valve-in-valve procedures.
Introduction Many studies have aimed at identifying additional prognostic tools to guide treatment choices and patient surveillance in lung cancer by assessing the expression of individual proteins through immunohistochemistry (IHC) or, more recently, through gene expression-based signatures. As a proof-of-concept, we used a multi-cohort, gene expression-based discovery and validation strategy to
Human telomerase reverse transcriptase (hTERT) is a critical factor in unlimited cell proliferation and immortalization, with numerous studies demonstrating that high expression of hTERT is a poor prognostic factor in various types of cancer. Ubiquitin-conjugating enzyme E2D 3 (UBE2D3) is a member of the E2 family, and participates in the ubiquitin proteasome pathway to regulate basic cellular act

In this prospective study, 25 consecutive patients with untreated primary hypothyroidism were tested with a highly sensitive perimetric technique, since a high prevalence of visual field defects has been described in this condition. All patients had clinical hypothyroidism, a serum TSH value greater than 20 mU/l (reference range 0.4-4.0) and decreased/low normal serum total T4 concentration. Visua
High plasma levels of oestrogens are associated with increased breast cancer risk. If smoking, as has been suggested, have both a tumour initiating mutagenic effect and a protective anti-oestrogenic effect, one would assume that smokers who give up smoking have the highest incidence of breast cancer. This was evaluated in the follow-up of a cohort of 10,902 women of whom 4,359 were premenopausal.
