In this work extensions to principal component analysis (PCA) for wastewater treatment (WWT) process monitoring are discussed. Conventional PCA has some limitations when used for WWT monitoring. Firstly, PCA assumes that data are stationary, which is normally not the case in WWT monitoring. Secondly, PCA is most suitable for monitoring data that display events in one time-scale. However, in WWT op

The antiproliferative activity, and the capability of priming of glycosaminoglycan chains, of two series of peracetylated mono- and bis-xylosylated dihydroxynaphthalenes have been investigated for normal HFL-1 cells, as well as transformed T24 cells, and compared to the unprotected analogs. Our data show increased antiproliferative activity upon peracetylation, but a loss of selectivity towards T2

The aim of this study was to investigate construct validity and internal consistency of a modified version of the Consumer Emergency Care Satisfaction Scale used on persons accompanying emergency department patients. The sample comprised 128 persons. The results showed satisfactory reliability, and an exploratory factor analysis revealed 3 factors: caring, teaching, and clinical competence. The mo

In this thesis, we propose methods based on constraint programming (CP) for solving an optimization problem in telecommunications, the single shortest path routing problem. The problem is to find optimal values for a set of routing configuration parameters in a shortest path routing protocol, for a given network. With optimal parameters, traffic is routed through the network in a way which is opti

We present a novel bonding technique developed for the fabrication of a cantilever-based biosensing system with integrated optical read-out. The read-out mechanism is based on single-mode waveguides fabricated monolithically in SU-8. For optimal operation of the read-out mode, the cantilever waveguides should be homogenous and this bonding technique ensures free-hanging cantilevers that are surrou

En vanlig klocka kan hjälpa till med när och hur länge. Den kan öka lugnet och framförhållningen men den kan också öka hetsen och minska marginalerna. Almanackan kan stödja planering, överblick och tillbakablick. Även den kan både brukas och missbrukas

We have measured radiative lifetimes for selenium and tellurium resonance levels by using short pulse laser excitation in differentially heated resonance cells. We obtained tau(3S1 Se I) = 2.9(5) ns and tau(3S1 Te I) = 3.1(5) ns, which together with branching ratio values given by Ubelis and Berzinsh yield the absorption oscillator strength f(abs)(Se I, 196.0 nm) = 0.074(16) and f(abs)(Te I, 214.3

Tensins are proposed cytoskeleton-regulating proteins. However, Tensin2 additionally inhibits Akt signalling and cell survival. Structural modelling of the Tensin2 phosphatase (PTPase) domain revealed an active site-like pocket receptive towards phosphoinositides. Tensin2-expressing HEK293 cells displayed negligible levels of plasma membrane phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P

Background: Polymorphism within the same species, population, and sex is an interesting problem for the evolutionary biologist, since differences in fitness between the morphs have to cancel out over evolutionary time, otherwise morphs of lower fitness would become extinct. One way this may be achieved is through the adoption of different morph-specific reproductive strategies, allowing morphs to

Examination of nationalist ideologies via two films from the former Yugoslavia in which the underground plays a major role – Emir Kusturica's Underground and Srdjan Dragojevic's Pretty Village, Pretty Flame.
