This work deals with different aspects of air movements in building components . The investigation shows to what degree the concept of fluid mechanics can be applied to problems concerning air flows in building Components. The applicable parts of fluid mechanics are presented as thoroughly as possible. Based on this concept, routines are outlined to make it possible to handle complex flow and pres

This paper presents the results of one of the first measurement campaigns for the double-directional characterization of outdoor to indoor wireless propagation channels. Such channels play a vital role for cellular systems with multiple antenna elements at transmitter and receiver, i.e. multiple-input multiple-output (MIMO) systems. Measurements were performed at 5.2 GHz between 53 different recei

OBJECTIVE: To explore the risk factors that have been suggested to be associated with the development of SLE. METHODS: A case-control study was performed and a questionnaire was developed to obtain the data. Consecutive female incident cases diagnosed between 1981 and 1999 in a defined geographical area in southern Sweden were included. Controls, matched for calendar year of birth, were selected r

To clarify the effects of solid fat and liquid oil on dough in more detail in a simpler system, gluten-starch doughs with different gluten contents were investigated. The results from rheological measurements indicate that dough with a higher starch content has less resistance to strain and dough with a lower starch content has a rubber-like structure. The effects of the physical state of nonpolar

The anti-inflammatory effect of purified honey bee venom (HBV) was studied using a recently described animal model in which preformed immune complexes were injected into rabbit knee-joints. As little as a single injection of 1.2 micrograms HBV/kg body weight subcutaneously significantly reduced the immune complex induced joint inflammation as measured by reduction in leukocyte counts in the joint

A convenient synthesis of benzene-1,3,5-tricarbaldehyde was developed as well as benzaldehyde derivatives carrying one or two latent aldehyde groups. The asymmetric derivatives may serve as versatile scaffolds for the synthesis of sectorial dendrimers and multifunctional molecules.

Popular Abstract in Swedish Skulle p53-målgenen TRIM22 kunna skydda mot cancer uppkomst? Frisk blodbildning En frisk vuxen människa har mellan fyra och sex liter blod, beroende på individens kroppsstorlek. Blodet produceras i benmärgen som finns i skelettbenen. Varje sekund bildas normalt i benmärgen tre till fyra miljoner blodkroppar från våra stamceller. Blodkropparna är specialiserade celler The tumor suppressor gene p53 is a transcription factor that mediates cell cycle arrest, apoptosis and differentiation. p53 mediated differentiation of leukemic cells depends on the transcriptional activity of p53 but so far no obvious differentiation inducing target gene has been identified. Using a cDNA microarray analysis, I identified TRIM22/Staf50 as a novel direct target gene to p53. The fun

In this paper stability and dynamic properties of voltage and frequency droop control of power electronic converters are investigated for a distributed generation system. Droop control is utilized to share active and reactive power among the source converters. The voltage and frequency controllers are designed so that stand-alone converter operation feeding constant power loads performs satisfacto

Small-angle, two-particle correlation functions have been measured for Ar-36+Sn-112,Sn-124 collisions at E/A=61 MeV. Total momentum gated neutron-proton (np) and proton-proton (pp) correlations are stronger for the Sn-124 target. Some of the correlation functions for particle pairs involving deuterons or tritons (nd, pt, and nt) also show a dependence on the isospin of the emitting source.

Popular Abstract in Swedish Östeuropeisk industri är ökänd både för sin miljöpåverkan och för sin besvärliga ekonomiska sits. Detta gör att resurserna som finns tillgängliga för miljöarbete är små - om dom finns överhuvudtaget. Den möjlighet som då återstår ligger i den förebyggande miljöskyddsstrategin där förbättringarna uppnås genom att gå in i produktionsprocesserna och effektivisera användninSince 1991 cleaner production projects have been pursued by the donors in Eastern European industry. These projects have aimed at demonstrating the benefits of a preventive approach to environmental protection, and to train people within the industry to perform the cleaner production assessments that constitute the core element of the preventive approach. The large merit of the preventive approach

The influence of personality factors on the appraisal of subjective quality of life in individuals with schizophrenia or schizoaffective disorder is not much investigated. The present study examined this relationship in a sample of 104 patients living in the community. The temperament and character inventory was used to assess personality and the Lancashire quality of life profile was used to asse

Thirty-two Norway spruce [Picea abies (L.) Karst.] and Scots pine (Pinus sylvestris L.) stands in southern Sweden were studied for a period of 12 years to evaluate acidification-induced chemical changes in the soil. Soil, at 20-30 cm depth in the mineral layer, was sampled three times during this period (1988, 1993 and 1999). The results show that pH(BaCl2) in mineral soil decreased by, on average

The effect of ethanol exposure on muscarinic receptor-stimulated expression of c-fos was investigated in SH-SY5Y cells. Four days of ethanol exposure enhanced carbachol-stimulated c-fos mRNA expression, analyzed with Northern blot, and Fos/AP-1 binding activity, measured with gel mobility super shift assay. Pre-incubation with muscarinic antagonists or the protein kinase C inhibitor GF109203X demo
