The electric field-assisted charge carrier photogeneration in a Ladder-Type Methyl substituted Poly(Para-Phenylene) was investigated by studying the electromodulated ultrafast transient differential absorption spectra and kinetics. The field stimulated appearance of the polaron absorption and quenching of the singlet exciton absorption proves that dissociation of excitons into geminately bound ele

The structural gene LPGVI (1463 bp including 6 introns), characterized from the white-rot basidiomycete Trametes versicolor (PRL 572), encodes a 342-residue mature polypeptide of 36.7 kDa, preceded by a 26-residue signal/propeptide. LPGVI is identified as the gene encoding the 43 kDa lignin peroxidase isozyme LP7 as based on the partial amino acid sequence information available. The polypeptide de

The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics. The thesis include the construction and evaluation of different variable selection te

Investigation of photoinduced processes in different C60–Sn nanostructures excited by 150 fs laser pulses at 400 nm (109 W/cm2) was performed with femtosecond supercontinuum probing of difference absorption and reflection in the spectral range of 400–1600 nm. The dynamics of relaxation are quite different for various nanostructures depending on the deposition mode and the ratio of tin and fulleren

Cross-sectional studies have reported strong correlations between plasma levels of complement C3, insulin, and glucose. This prospective study explored whether elevated levels of C3, C4, and other inflammation-sensitive plasma proteins (ISPs; fibrinogen, orosomucoid, α1-antitrypsin, haptoglobin, and ceruloplasmin) are associated with the development of diabetes. Plasma proteins were measured in 2,

Hummingbird hawkmoths were tested for their preferences for different types of sugar. In triple choice tests, moths sucked for longer periods from sucrose than from fructose and glucose. Naive moths released in a large flight cage and monitored over 24 days, drank on average 137 mul sucrose, 67 mul fructose and 7 mul glucose daily. In an independent test, moths spent more time feeding from sucrose

Spring migration of arctic breeding birds, mainly waders and Dark-bellied Brent Geese Branta bernicla, was followed by tracking radar in Lund, South Sweden, during 1998-2001 in order to evaluate the capacity of these birds to exploit favourable winds. A total of 888 radar tracks were collected. Here I report on measured flight speeds, flight altitudes and winds and compare these with results from

In linear response, the electric conductance of mesoscopic, two-terminal devices is symmetric with respect to the direction of an external magnetic field. The conductance symmetry, in general, breaks down in the non-linear regime of transport. Here we consider semiconductor quantum dots and show certain symmetries survive in the non-linear conductance with respect to the bias voltage and magnetic

The high-resolution far-infrared absorption spectrum of the gaseous molecular complex H3N-HCN is recorded by means of static gas-phase Fourier transform far-infrared spectroscopy at 247 K, using a synchrotron radiation source. The spectrum contains distinct rotational structures which are assigned to the intermolecular NH3 libration band v(9)(1) (v(B)) of the pyramidal H3N-HCN complex. A rovibrati

One-nucleon removal reactions at relativistic energies have been used as a spectroscopic tool to characterise the ground state properties of several neutron-rich isotopes in the sd-shell. Using the FRS at GSI, the longitudinal momentum distributions of the emerging fragments after one-nucleon removal were measured. The relative contributions of the remaining fragments in their ground and excited s

This study analysed the costs of median and ulnar nerve injuries in the forearm in humans and factors affecting such costs. The costs within the health-care sector and costs of lost production were calculated in 69 patients with an injury to the median and/or ulnar nerve in the forearm, usually caused by glass, a knife, or a razorblade. Factors associated with the variation in costs and outcome we

Denna rapport utgör redovisningen av tredje och sista etappen i ett arbete om utbytbarhet, material- och energiflöden i installationer för byggnader. De tre etapperna är redovisade i varsin rapport och utgör tillsammans en licentiatuppsats. Första etappen i arbetet utgjordes av litteraturstudien "Installationer ur ett livscykelperspektiv" (Rapport (TABK-99/3058) med syftet att redogöra för det a

Using two epochs of HST/WFPC2 images of the metal-rich globular clusterNGC 6528 we derive the proper motions of the stars and use them toseparate the stars belonging to NGC 6528 from those of the Galacticbulge. The stellar sequences in the resulting colour-magnitude diagramfor the cluster are significantly better determined than in previouslypublished data. From comparison of the colour-magnitude
