Local factors influencing the rate of diffusion of residential photovoltaic (PV) systems are insufficiently understood. This multiple-case study explored five Swedish municipalities which have had a particularly high PV density in terms of number of installations per capita, compared to other municipalities. The aim was to identify and assess local factors that could explain these relatively high

Electron–ion coincidence measurements with energy-resolved electrons are a powerful tool in studies of molecular fragmentation processes, since fragmentation from a specific doorway state can be monitored while the remaining reactions are discriminated. Presently, we have applied this technique in measurements of coincidence spectra of the CD4 and SF6 molecules after valence and core electron exci

Utbildning har förmodligen aldrig haft en mer upphöjd ställning än under de senaste decennierna. Samtidigt befinner sig skolan, eller snarare skolinstitutionen, i kris. Krisen har medfört att lärarna mer definieras som en del av problemet än av lösningen. Försöken att styra läraren i riktning mot en ”maktens lärare”, en anställd som lojalt gör det uppdragsgivaren vill, har därför också stått högt

Whereas most research in SLA assumes the relationship between the first language (L1) and the second language (L2) to be unidirectional, this study investigates the possibility of a bidirectional relationship. We examine the domain of manner of motion, in which monolingual Japanese and English speakers differ both in speech and gesture. Parallel influences of the L1 on the L2 and the L2 on the L1

Vad händer när en spricka i putsen utsätts för hydrostatiskt vattentryck? Kan vatten transporteras i isoleringen? Hur påverkar horisontella och vertikala isolerskarvar vattenledningen? Kan vatten transporteras i gränsskiktet mellan puts och isolering? Vad händer om vatten når isolerhållarna? Kan vatten nå bakomliggande stomme? I ett forskningsprojekt vid Lunds tekniska högskola har experimentella

Synthetic peptides derived from the sequence surrounding tyrosine-857 in the human platelet-derived growth factor (PDGF) beta-receptor were used to elucidate the requirement for length and presence of negative and positively charged amino acids in substrates of the PDGF beta-receptor protein tyrosine kinase. The measured Km for the different peptides were all in the range 1-10 mM. A peptide of onl

The purpose of this descriptive cohort study was to describe patients with hip fracture on the basis of ASA physical status and to identify preoperative risk factors associated with postoperative outcome up to 4 months after surgery. Data were collected prospectively through the Swedish National Hip Fracture and Anesthetic registers and retrospectively from medical and nursing records. The 428 pat

To identify from a patient's perspective, difficulties and differences in the comprehension of five global presenteeism measures in patients with inflammatory arthritis and OA across seven countries.

Recently, we proposed using Capon's minimum variance principle to find the fundamental frequency of a periodic waveform. The resulting estimator is formed such that it maximizes the output power of a bank of filters. We present an alternative optimal single filter design and then proceed to quantify the similarities and differences between the estimators using asymptotic analysis and Monte Carlo s
