High proteinuria selectivity index based upon IgM is a strong predictor of poor renal survival in glomerular diseases

BACKGROUND: The transport of large proteins across the glomerular capillary wall (GCW) may increase several fold in glomerular diseases. The occurrence of IgM in urine is a consequence of the presence of large defects or shunts in the GCW, whereas albuminuria is probably a result of an altered charge- and size-selectivity of the GCW. In order to examine whether patho-morphological differences infl

Weyl product algebras and modulation spaces

We discuss algebraic properties of the Weyl product acting on modulation spaces. For a certain class of weight functions omega we prove that M-(omega)(p,q) is an algebra under the Weyl product if p epsilon [1, infinity] and 1

The effect of packaging material on the sensory properties of broccoli.

Three different commercially available polymeric films were studied to determine their effect on the sensory properties of fresh broccoli (Brassica oleracea L. var. Italica cv. ‘Marathon’). The polymer materials investigated were oriented polypropylene (OPP), polyvinyl chloride (PVC) and one low density polyethylene (LDPE) which contained an ethylene absorber. The fresh broccoli was packaged and s

Behind the very notes: Playful creativity in coping with notation

This study explores musicians' ways of taking and giving meaning to notation in Western tonal music. From a socio-cultural theoretical perspective relations between traditions and individuals were especially accounted for. Linked to this perspective the method for the study was developed. Experienced pianists commented on well-prepared performances of one freely chosen work, and prescribed pieces

Evaluation of a NOx reduction system on an engine rig under stationary operation

The NOx storage and reduction approach was applied on a full-scale engine rig under stationary operation. NOx reduction experiments were performed and a catalyst model developed and tested. The exhaust system was equipped with a bypass system. A NOx reduction of 25-53% was achieved. At low temperature, higher values were reached when the exhaust gas bypass was longer than the injection period.

Maximally aligned states in Ag-99

Excited states of Ag-99 were populated via the Cr-50 + Ni-58 (261 MeV) reaction using the NORDBALL detector array equipped with charged-particle and neutron. detector systems for reaction channel separation. On the basis of the measured gammagamma-coincidence relations and angular distribution ratios a significantly extended level scheme has been constructed up to E-x similar to 7.8 MeV and I = 35

Failure monitoring in water distribution networks

An algorithm for the burst detection and location in water distribution networks based on the continuous monitoring of the flow rate at the entry point of the network and the pressure at a number of points within the network is presented. The approach is designed for medium to large bursts with opening times in the order of a few minutes and is suitable for networks of relatively small size, such

Utvärdering av Småhusskadenämndens arkiv avseende krypgrunder : genomgång av arkivet

Denna rapport redovisar resultat från en genomgång av Småhusskadenämndens arkiv. I genomgången av arkivet studerades uteluftsventilerade krypgrunder som haft fukt- och mögelskador och åtgärdats för dessa med bidrag från nämnden. Småhusskadenämnden inrättades 1986 och har under perioden 1986 - 1997 behandlat 9.227 ärenden av vilka cirka 35 % har beviljats bidrag. Ur detta material valdes 102 grunde

A cluster of genes encoding major isozymes of lignin peroxidase and manganese peroxidase from the white-rot fungus Trametes versicolor

A gene cluster from the white-rot basidiomycete Trametes (Coriolus) versicolor (Tv) PRL 572 containing three structural genes, LPGIII, LPGIV and MPGI, was characterized. The genes are arranged in the same transcriptional direction, within a 10-kb region, and found to encode quantitatively dominant isozymes of lignin peroxidase (LP) and manganese peroxidase (MP). The second gene in sequence, LPGIV,

Influence of laser phase and frequency fluctuations on photon-echo data erasure

Erasure of data stored by use of photon echoes has been investigated as a function of data writing time and data storage time. The results clarify the requirements on laser phase and frequency stability for performing photon-echo data erasure. The analysis of phase and frequency stability of a light source by the photon-echo erasure process is illustrated. A theoretical analysis emphasizing the ph

Hidden Markov models - Traffic modeling and subspace methods

The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. New important properties, both on macroscopic and
