Dynamics of Energy Efficient Lighting
The paper discusses the results of a time dynamic analysis of the possible effects of government and utility sponsored energy efficiency programmes on lighting energy use in Sweden. Scenarios are developed of electricity demand and efficiency improvement, based on various types of energy performance standards and utility demand-side management (DSM) investments. The scenarios account for the dynam

Företag, regioner och internationell konkurrens : Om regionala resursers betydelse
The overall purpose of this thesis is to study regional variation in the international competitiveness (export capacity, market orientation and production aboard) of Swedish manufacturing industry, and to contribute to explaination of this variation. The explanation is sought for in differences in regional production milieu as well as in differences in localization of industrial sectors and claims
Xenotransplantation on the arena of a university hospital
Pitfalls in the interpretation of long-term inhalation experiments
Age- and weight-matched groups of mice were enclosed in airtight chambers and exposed to clean, filtered air for 1 month. At the end of the exposure period, body, liver and spleen weights and plasma butyrylcholinesterase (BuChE) activity were measured. More than twice as many significant differences in these parameters occurred compared with the expected results if only random differences existed
Pristane, a non-antigenic adjuvant, induces MHC class II-restricted, arthritogenic T cells in the rat.
Pristane-induced arthritis (PIA) in rats, a model for rheumatoid arthritis (RA), is a T cell-dependent disease. However, pristane itself is a lipid and unable to form a stable complex with a MHC class II molecule. Therefore, the specificity and function of the T cells in PIA are as unclear as in rheumatoid arthritis. In this study, we show that activated CD4+ alphabetaT cells, which target periphe
Pre-eclampsia is a potent risk factor for deterioration of retinopathy during pregnancy in Type 1 diabetic patients
The aim of the present study was to examine the influence of pregnancy on deterioration of retinopathy in patients with Type 1 diabetes mellitus. Sixty-five pregnant Type 1 diabetic women attending the University Hospital in Lund were studied retrospectively. The degree of retinopathy, and levels of HbA1c and blood pressure 12 months before, during, and 6 months after pregnancy were compared of th
Fetal ductus venosus, middle cerebral artery and umbilical artery flow responses to uterine contractions in growth-restricted human pregnancies.
Objective To explore fetal ductus venosus (DV) flow velocity changes relative to umbilical artery (UA) blood flow and brain-sparing flow (BSF) during uterine contractions. Methods Forty-five term fetuses suspected of having growth restriction were exposed to an oxytocin challenge test (OCT) with simultaneous Doppler velocimetry in the UA, middle cerebral artery (MCA) and DV. Basal BSF was defined
Long term efficacy and safety of cyclosporin versus parenteral old in early rheumatoid arthritis: a three year study of radiographic progression, renal function, and arterial hypertension
Objective: To compare the three year safety and efficacy of cyclosporin and parenteral gold in the treatment of early, active, severe rheumatoid arthritis (RA), and to study the reversibility of cyclosporin associated renal dysfunction in patients who discontinued cyclosporin treatment. Methods: The patients continued to receive cyclosporin or parenteral gold in an 18 month open extension to an 18
U-EPX levels and wheezing in infants and young children with and without RSV bronchiolitis
An association between severe infant bronchiolitis due to respiratory syncytial virus (RSV) and subsequent wheezing is well documented. High levels of urinary eosinophil protein X (U-EPX) have been related to active disease in asthmatic children. The aim of this study was to analyse whether RSV bronchiolitis leads to an increase in U-EPX levels and whether wheezing is more common in children with
An evolutionary analysis of the aetiology and pathogenesis of juvenile-onset myopia
The available evidence suggests that both genes and environment play a crucial role in the development of juvenile-onset myopia. When the human visual system is examined from an evolutionary perspective, it becomes apparent that humans, living in the original environmental niche for which our species is genetically adapted (as hunter-gatherers), are either slightly hypermetropic or emmetropic and

Styr- och reglertekniska funktioners inverkan på energiförbrukningen
Rapporten behandlar styr- och reglertekniska funktioners inverkan på energiförbrukningen i byggnader. Den omfattar presentation av undersökta objekt med beskrivning av de olika installationssystemen, redogörelse för redan gjorda driftserfarenheter samt beskrivning av energibesparande modifieringar av driftsätt.
The eta(c)(2980) formation in two-photon collisions at LEP energies
eta(c)(2980) production in gammagamma interactions has been detected via its decays into K(s)(0)K(-/+)pi(-/+), K+K-K+K- and K(+)K(-)pi(+)pi(-) in the data taken with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative width averaged over all observed decay channels is Gammagammagamma=13.9+/-2.0(stat.)+/-1.4(syst.)+/-2.7 (BR) keV. No direct decay channel eta(c)-->pi(+)pi(-)pi(+)
Chlorophyll biosynthesis in higher plants. Regulatory aspects of 5-aminolevulinate formation
Chlorophyll, heme, phytochrome and siroheme biosynthesis in higher plants is regulated by the supply of their precursor 5-aminolevulinate (ALA), which is derived from glutamate. Glutamate conversion to ALA occurs only in the plastid and requires chloroplast coded tRNA(Glu) and nuclear coded glutamyl-tRNA synthetase, glutamyl-tRNA reductase and glutamate 1-semialdehyde aminotransferase. The chromos
