Perceptual consumer requirements are often disregarded in the product development process. The consequence of this is that products may become more attractive to the design practitioners than to the target consumers. This paper describes the development of a new internet based tool, VIPET (Visual Internet Product Emotion Tool), that can be used for global evaluation of visual product qualities by

We study the self-adjoint Pauli operators that can be realized as the square of a self-adjoint Dirac operator and correspond to a magnetic field consisting of a finite number of Aharonov–Bohm solenoids and a regular part, and prove an Aharonov–Casher type formula for the number of zero-modes for these operators. We also see that essentially only one of the Pauli operators are spin-flip invariant,

In the 20 years since the discovery of Helicobacter pylori the number of formally described Helicobacter spp. has increased dramatically. The majority of species in the genus have been associated with some form of pathology. Similar to other Gram-negative bacteria, all helicobacters have lipopolysaccharides or endotoxins in the outer leaflet of their outer membrane which is an important modulator

Excited states have been studied in Ar-35 following the O-16(Mg-24,1alpha1n)Ar-35 fusion-evaporation reaction at 60 MeV using the Ge-detector array GASP. A comparison with the mirror nucleus Cl-35 shows two remarkable features: (i) A surprisingly large energy difference for the 13/2(-) states, in which the hitherto overlooked electromagnetic spin-orbit term is shown to play a major role, and (ii)

5-S-cysteinyldopa and 6-hydroxy-5-methoxyindole-2-carboxylic acid are important intermediate metabolites in the formation of cutaneous melanin pigment. Since they both are serious candidates as markers of melanoma progression, their stability in urine has been investigated during storage at various conditions. The results show that storage at -20 degrees C is necessary. Both compounds are nonstabl

Chromosome aberrations, in particular translocations and their corresponding gene fusions, have an important role in the initial steps of tumorigenesis; at present, 358 gene fusions involving 337 different genes have been identified. An increasing number of gene fusions are being recognized as important diagnostic and prognostic parameters in malignant haematological disorders and childhood sarcom

BACKGROUND The sperm chromatin structure assay (SCSA) parameter DNA fragmentation index (DFI) has been shown to predict in vivo and in vitro fertility. So far most SCSA studies have been based on SCSA analysis performed on neat semen. The aim of this study is to assess whether SCSA analysis of sperm prepared by density gradient centrifugation (DGC) could add more information in regard to the predi

AIM: To investigate whether perinatal events, intrauterine or postpartum, are associated with the development of primary sclerosing cholangitis (PSC) later in life. METHODS: Birth records from 97 patients with adult PSC in Sweden were reviewed. Information on perinatal events including medications and complications during pregnancy, gestation length, birth weight and length were collected. Two con

Pathogenic bacteria often produce proteinases that are believed to be involved in virulence. Moreover, several host defence systems depend on proteolysis, demonstrating that proteolysis and its regulation play an important role during bacterial infections. Here, we discuss how proteolytical events are regulated at the surface of Streptococcus pyogenes during infection with this important human pat

Palaeomagnetic data from the 337 Ma Mageroy dykes (northern Norway) are of exceptionally high quality, and a positive contact test along with an existing regional result from the Silurian Honningsvag Igneous Suite attests to a primary Early Carboniferous magnetic signature. The palaeomagnetic pole (S 14.8degrees, E320.1degrees, dp/dm = 4.4/8.6degrees) is the first Early Carboniferous pole from Bal

The visual content of out-of-body experiences (OBEs) has received little attention but a number of theories of OBEs include implicit predictions regarding the determinants of this phenomenological feature. Hypnagogic imagery and unusual sleep experiences, weak synaesthesia and preference for employing object and spatial visual imagic cognitive styles were psychometrically measured along with the i

Øresund EcoMobility contributes to knowledge creation for sustainable transport and green logistics, city transport, and energy systems with a specific focus on the conditions and needs of the Øresund region. In this book, long distance goods transport and strategies for green corridors through the Øresund and Europe are studied, multi-criteria models for analysis in transport and infrastructural

The Swedish Academy of Sciences was founded in 1739. The article presents and discusses the explicit language policy of the academy and analyzes some aspects of the language and rhetoric of the transactions (in Swedish) of the academy:textual organization, objectivity, rhetorical devices, lexical apparatus, syntactic machinery and techniques of presentation. Special interest is devoted to the tran
