Utilization of an ethanol driven, combustion-based power generator promises high-efficiency combustion in diesel-like engines and avoids problems connected to shrinking supplies of fossil fuels since fuels like ethanol or dimethyl ether can be produced from renewable resources. Fuel injection into such generator through a piezoelectric micro mass flow controller (MMFC) features low power consumpti
Background: Survivors of Hodgkin lymphoma (HL) in childhood have an increased risk of subsequent malignant neoplasms (SMNs). Herein, the authors extended the follow-up of a previously reported Late Effects Study Group cohort and identified patients at highest risk for SMNs to create evidence for risk-based screening recommendations. Methods: The standardized incidence ratio was calculated using ra
Bone marrow transplantation (BMT) is a conceptual and elegant example of stem cell therapy, rendered possible by the dual capacity of hematopoietic stem cells (HSCs) to self-renew and differentiate. These defining features ultimately ensure the production of all blood cell lineages and simultaneous maintenance of the stem cell pool, thereby maintaining lifelong homeostasis. Banked umbilical cord b
During the past 15 years the Scandinavian Sarcoma Group has treated 140 patients with Ewing's sarcoma. Two protocols have been used. SSG IV included 52 patients between 1984 and 1990 and SSG IX, 88 patients since 1990. After 5 years of treatment, local recurrences occurred in 19% of the patients (M0 + M1) in the SSG IV group and 10% in the SSG IX group. Distant metastases developed in 57% of the M
This doctoral thesis consists of six studies concerning persons with insulin dependent diabetes mellitus (IDDM). The first two deal with relationships between life events, social support and metabolic control (HbA1C) over a two year period. For the female subjects, results obtained for this period were inconsistent. For the male group, negative life events and poor social support were found to be
The overall aim of this work was to evaluate symptoms, subjectively scored function and physical outcome in patients with surgically treated ankle fractures. Another aim was also to evaluate the effects of a standardised but individually suited supervised training program. In all, 209 patients with surgically treated ankle fractures were included in three different samples: 54 individuals aged 18-
A secondary sexual character may act as an honest signal of the quality of the individual if the trait bears a cost and if its expression is phenotypically condition dependent. The cost of increasing the trait should be tolerable for individuals in good condition but not for those in a poor condition. The trait thus provides an honest signal of quality that enables the receiver to choose higher qu
Seventy-three Swedish blood donors (52 men, 21 women; median age 36 years) repeatedly reactive for hepatitis C antibodies (anti-HCV C-100-3) were tested with a second-generation (2nd-gen) anti-HCV Elisa and a 4-band recombinant immunoblot assay (RIBA 2). These results were correlated to serum alanine aminotransferase (S-ALAT), liver morphology and viremia as detected by 'nested' polymerase chain r
This thesis explores women’s access to property in Kenya. It consists of three parts. The first gives the Kenyan background, the theoretical and methodological approach. The second presents the findings in relation to the social construct of the gender and elaborates them in the contexts of women´s subsistence work, colonization and its aftermath and women´s formation of organizations. The third p
Popular Abstract in Swedish Användningen av informations och kommunikationsteknik (IKT eller IT) påverkar vårt sätt att kommunicera i arbetslivet. Det underlättar distansarbete och skapar möjligheter till s.k. virtuella möten - att samarbeta utan att träffas fysiskt. Detta kan i sin tur påverka behovet av pendlings- och tjänsteresor, genom att vi får tillgång information, en funktion eller en tjänInformation and Communication Technologies change the way we work and communicate, enabling us to telework and to have virtual meetings - collaborating without a physical meeting. This can influence the need for commuting and business travel by provision of access to an activity without mobility - virtual mobility. The large environmental impact of travel makes this potential travel reduction inte
INTRODUCTION: General practitioners are often interested in doing research but are hampered by lack of time and research training. Interpreting the results of others can also be difficult. For this reason a course in basic research methods for GPs was started in Sweden in 1989. It was originally aimed at GPs but was later extended to hospital physicians as well. The course is given regionally and
Popular Abstract in Swedish Parallellt med att kommunerna under 1990-talet fick ett utvidgat ansvar för t.ex. vården av och omsorgen om äldre och funktionshindrade gavs de större frihet att lokalt bestämma över sina organisationsformer. Omständigheterna ledde till ett starkt kommunalt reformtryck, inte minst genom de reformförslag som på olika sätt och i varierande grad utmanade den traditionella
Is the decline of the increasing incidence of non-Hodgkin lymphoma (NHL) in Sweden and other countries a result of cancer preventive measures? The yearly age-standardized incidence of NHL increased significantly in Sweden during 1971-1990, for men an average of 3.2% and for women 3.1%. The corresponding figures for 1991-2000 were -0.8% and -0.2%, respectively. A decline of the increasing incidence
Popular Abstract in Swedish Ljus kan beskrivas som en elektromagnetisk våg och har då en viss våglängd. Färgen på ljuset förändras beroende på våglängden. Av det synliga ljuset har violett ljus den kortaste våglängden och rött ljus den längsta. Det finns även elektromagnetisk strålning utanför det synliga området, från Röntgenstrålning till radiovågor. Det vi kallar det optiska området sträcker siAtoms and molecules absorb and emit light at certain, welldefined wavelengths, and this forms the basis of spectroscopy. The wavelengths are given by the discrete energy levels of the atoms/molecules. When illuminated by light of a suitable wavelength, the light will be absorbed, making it possible to deduce information on the presence and concentration of various elements and compounds. When ato
Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. Over time, there is a steady deterioration of glycaemic control that raises the need for effective therapy targeted at the underlying defects in
Thermodynamic parameters are presented here illustrating the effects caused by the two anticancer active metal complexes cisplatin and oxaliplatin after introduction into four closely related RNA and DNA duplexes. The duplexes used are blunt end, fully complementary 15-mer duplexes with a centrally located either GG- or GNG (here: N = T or U) binding site. For all duplexes, a common trend of reduc
Popular Abstract in Swedish Näthinnan (retina) ligger längst bak i ögat och fungerar som filmen i en kamera. Stavar och tappar registrerar ljus och signalen går via nerver till syncentra i hjärnan. Blodkärl löper genom näthinnan och förser cellerna med syre och näring samt transporterar bort slaggprodukter. Kärlsjukdomar, som t.ex. diabetes, blodproppar i näthinnan till följd av åderförkalkning oc
