Mucins in normal and diseased airways

Popular Abstract in Swedish I luftvägarna finns ett sekret, "mukus" eller "slem", som tillsammans med flimmerhårens rörelser förhindrar skadliga ämnen att nå lungorna. Denna sk mukociliära transportmekanism är av yttersta vikt för vår hälsa och överproduktion av mukus tillsammans med försämrad mukociliär transport kan innebära fara för livet. Mukus innehåller till största delen vatten (95-99%) menMucus glycoproteins (mucins) are the principal constituents of respiratory secretions in health and disease. The increased 'acidity' of mucin producing cells in the bronchitic airways is not reflected in a change of negative charge of bronchitic mucins. Furthermore, the size and macromolecular properties of mucins from chronic bronchitic sputa do not differ significantly from those in normal airwa

Julklappsrobot visar vägen för framtidens programmering

Borta är tiden då det krävdes experter för att programmera robotar. Tack vare forskning på Lunds Tekniska Högskola kan robotar numera läras upp genom att helt enkelt visa dem vad som ska göras. Detta har bland annat resulterat i roboten Yumi som kan slå in julklappar. Nästa steg för forskarna är att programmera robotar genom att få dem att förstå mänskligt tal.

Diagnostic Tools for the Undulator System of the Seeded HGHG-FEL at MAX-lab

Within a collaboration between MAX-lab and BESSY a one stage seeded HGHG-FEL has been set up at Maxlab. BESSY has built the undulator system consisting of a modulator, a radiator and an electromagnetic chicane. BESSY has also installed three types of diagnostic tools: optical fibres for a fast Cherenkov beam loss detection, optical fibres for absolute dose measurements via their radiation-induced

Functional Studies of Telomere-Binding Proteins in Saccharomyces castellii

Telomeres are the ends of linear eukaryotic chromosomes. The telomeres are essential for solving the end replication problem and they stabilize the genome by protection from degradation. The telomeres also protect the chromosomal ends from by being recognized as DNA breaks by the repair machinery, which could lead to end-to-end fusions. Dysfunctional telomeres are implicated in many complex cellul

Hygro-Mechanics of Wood Fibre Composite Materials

The work presented in this thesis deals with modelling and testing of hygro-mechanical properties of wood fibre composite materials. The material studied experimentally is high pressure laminate, HPL, which is a wood fibre network composite, made up of craft paper impregnated with phenolic or melamine resin. An analytical model for the hygro-mechanical properties has been developed. The model calc
