Identification of cancer subtypes is the central goal in the cancer gene expression data analysis. Modified symmetry-based clustering is an unsupervised learning technique for detecting symmetrical convex or non-convex shaped clusters. To enable fast automatic clustering of cancer tissues (samples), in this chapter, the authors propose a rough set based hybrid approach for modified symmetry-based

This study explores the possibility that the delayed hypoperfusion observed after an ischemic insult might be due to vasoconstriction induced by the release of noradrenaline from nerves originating in the locus ceruleus. Bilateral 6-hydroxydopamine lesions of the ascending bundles from the locus ceruleus were carried out in the caudal mesencephalon of rats. Local CBF was measured with an autoradio

In search of factors influencing the outcome of an ischemic insult, we induced 10 min of forebrain ischemia in rats and assessed neuronal necrosis by quantitative histopathology after 1 week of recovery. Procedures for inducing ischemia included bilateral carotid artery clamping and reduction of blood pressure to 40–50 mm Hg by bleeding. To facilitate rapid lowering of blood pressure, a ganglionic

This chapter focuses on the use of doped carbon nanomaterials in catalysis. The availability of carbon nanotubes in the ‘90s and graphene about 10 years later, prompted the development of fundamental research and novel nanotechnologies. We discuss this topic from a point of view that links fundamental surface science to the field of catalysis, in order to present the state of the art.

Att en specifik utvärderingsforskning knappast existerade i Sverige före mitten av 1970-talet beror bl a på att socialpolitiska reformer normalt föregåtts av en planerings- och beslutsprocess som inneburit omfattande politisk kontrol och värdering, såväl före som under själva genomförandet. Förändringarna inom offentlig sektor, där det tidligare planeringstänkandet ersatts av en mål- och resultats

Environmental problems and technical systems in the society are fundamentally related to hydrology. Hydrology is a very comprehensive concept. In fact, there are at least ten independent disciplines within hydrology. Classical hydrology is a descriptive science with the water balance equation as almost the only means of quantifying computations. Hydrodynamics have now to some extent been introduce

The main objective of the paper is to briefly describe and exemplify some of the work that has been carried out within the STAMP project at IEA at Lund Institute of Technology within the field of mathematical modeling of wastewater treatment (WWT) processes. Three main areas have been identified - reduced-order models of the activated sludge process, modelling of biofilm processes including some e

En undersökning av de språkligt motiverade bearbetningarna som gjorts av psalmer från 1695 års svenska psalmbok inför de tre nya psalmboksutgåvor som följt därefter. Undersökningen avser de omkring 100 1695-psalmer som finns med i alla dessa tre senare psalmböcker och sönderfaller i morfologiska, lexikala, syntaktiska och textuella bearbetningsinsatser.
