Extraordinary transmission through subwavelength apertures is usually observed in a narrow bandwidth range, and the transmission outside this range is low, in agreement with classical results. The analysis presented here is based on the Babinet's principle and hence scattering by the complementary structure, where the apertures are replaced by finite scatterers. It is shown that the transmission c

We report preliminary clinical results of autofluorescence imaging of malignant and benign skin lesions, using pulsed 355 nm laser excitation with synchronized detection. The novel synchronized detection system allows high signal-tonoise ratio to be achieved in the resulting autofluorescence signal, which may in turn produce high contrast images that improve diagnosis, even in the presence of ambi

This study focuses on the embedding of new biotech solutions into three business landscapes - US, China and Taiwan. A "state-of-the-art" chromatography system tuned for operating in the step between laboratory and large-scale production is used as the common point of departure to investigate the supplier-user interfaces involving biotechnology in each of the three countries; the resource interacti

Deal & Kennedy tar i sin förståelse av företaget utgångspunkt i de riter och ritualer som utvecklas inom företag. Viktiga beståndsdelar i dessa ritualer är olika motton, förekomsten av "hjältar", speciella ceremonier som t.ex. fester samt det kulturella nätverket eller den dolda hierarkin inom företaget.

Aim: To characterize early amplitude-integrated electroencephalogram (aEEG) and single-channel EEG (aEEG/EEG) in very preterm (VPT) infants for prediction of long-term outcome. Patients: Forty-nine infants with median (range) gestational age of 25 (22-30) weeks. Methods: Amplitude-integrated electroencephalogram/EEG recorded during the first 72 h and analysed over 0-12, 12-24, 24-48 and 48-72 h,

Welinders Swedish history of archaeology: A review of Stig Welinder’s book “Min svenska arkeologihistoria” (My Swedish history of archaeology) (2003).

There is a functional relationship between the heparan sulfate proteoglycan glypican-1 and the amyloid precursor protein of Alzheimer disease. In wild-type mouse embryonic fibroblasts, expression and processing of the amyloid precursor protein is required for endosome-to-nucleus translocation of anhydromannose-containing heparan sulfate released from S-nitrosylated glypican-1 by ascorbate-induced,

Cytokines like interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha), released during the inflammatory process, play important roles in the development of airway hyperresponsiveness. The effects of these cytokines are mediated by cell surface receptors, specific for each cytokine. The expression of cytokine receptors is a dynamic process, where receptors can be up- or down-regula

Aim. The aim of this study is to examine associations between caregiver burden, perceived health and sense of coherence in family caregivers to persons with dementia living at home. Background. Most of the studies on family caregivers have focused on burden and morbidity. However, the caregiver's sense of coherence and perceived health have not been studied earlier in relation to caregiver burden.
