Most structured latex particles are formed in the nonequilibrium state as a result of the reaction kinetics proceeding faster than the phase separation kinetics. Of the many factors controlling such morphologies, the polarity and glass transition temperature (Tg) of the seed polymer are important. In order to study the direct effect of the seed polymer Tg on morphology, we produced a series of pol

Lignocellulose hydrolysate is an abundant substrate for bioethanol production. The ideal microorganism for such a fermentation process should combine rapid and efficient conversion of the available carbon sources to ethanol with high tolerance to ethanol and to inhibitory components in the hydrolysate. A particular biological problem are the pentoses, which are not naturally metabolized by the mai

Snapshot Spectral Imaging enables the acquisition of hyperspectral images (HSI) from 2D projected measurements employing specialized optical systems, such as the Coded Aperture Snapshot Spectral Imager (CASSI). Specifically, the CASSI system performs spatio-spectral codification of light obtaining 2D projected measurements. These measurements are then processed by algorithms to obtain the desired

In this paper, we take a fresh look at the determination of the transition matrix for a homogeneous, biisotropic particle employing the Null-field approach. The condition for passivity of the material is discussed. In particular, we focus on some previously unproved properties of the Beltrami spherical vector waves, such as completeness, orthogonality, and linear independence, which are all instru

Lead halide perovskites (LHPs) nanocrystals (NCs), owing to their outstanding photophysical properties, have recently emerged as a promising material not only for solar cells but also for lighting and display applications. The photophysical properties of these materials can be further improved by chemical engineering such as cation exchange. Hot carrier (HC) cooling, as one of the key photophysic

Popular Abstract in Swedish Denna avhandling har sin upprinnelse i utvecklingen av en metod för datorvisualis-ering och en metod för participativ ingenjörskonst. De två metoderna är intimt förknippade med varandra och benämns tillsammans “Computer Visualization in Participatory Engineering” (VIPE), något som på svenska skulle kunna benämnas ”Datorvisualisering för Participativ Ingenjörsvetenskap”.This thesis tells the initiation story of a computer visualization methodology and a participatory engineering methodology. The two methodologies are tightly coupled and for the purpose of this thesis, as a unit, named Computer Visualization in Par-ticipatory Engineering (VIPE). VIPE aims at a concurrent focus on technical and economical as well as ergonomic demands, by means of advancing communic

Purpose: To investigate the relative importance of spatial resolution and noise on the image quality of clinical radiographs. Methods: The spatial resolution and noise of fifteen digitised lumbar spine radiographs were altered with image processing. Three different MTF curves and three different Wiener spectra were combined into seven different combinations of spatial resolution and noise. These s

Popular Abstract in Swedish Systemisk lupus erythematosus (SLE) är en autoimmun reumatisk systemsjukdom som drabbar flera av kroppens olika organsystem, såsom rörelseapparat, hud och inre organ. Vidare ses en mångfald störningar i kroppens immunsystem. Sjukdomen drabbar oftast kvinnor. Vad som orsakar SLE är ännu så länge ofullständigt klarlagt, men man vet att yttre faktorer (miljöfaktorer) samveSystemic lupus erythematosus (SLE) is a complex autoimmune disease in which environmental factors interact with genetic factors in the development of the disease process and evolution of clinical manifestations. In this thesis both exogenous factors and host factors were investigated, as well as important immunopathological aspects including involvement of immune complex (IC), the complement syste

The Danish national return-to-work (RTW) program aims to improve the management of municipal sickness benefit in Denmark. A study is currently ongoing to evaluate the RTW program. The purpose of this article is to describe the study protocol. The program includes 21 municipalities encompassing approximately 19 500 working-age adults on long-term sickness absence, regardless of reason for sickness

This paper describes a named entity recognition (NER) system for short text messages (SMS) running on a mobile platform. Most NER systems deal with text that is structured, formal, well written, with a good grammatical structure, and few spelling errors. SMS text messages lack these qualities and have instead a short-handed and mixed language studded with emoticons, which makes NER a challenge on

Increased recirculation of process water has given rise to problems with formation of calcium oxalate incrusts (scaling) in the pulp and paper industry and in forest biorefineries. The potential in using oxalate decarboxylase from Aspergillus niger for oxalic acid removal in industrial bleaching plant filtrates containing oxalic acid was examined and compared with barley oxalate oxidase. Ten diffe

Photoexcitation of conjugated polymerfullerene blends results in population of a local charge transfer (CT) state at the interface between the two materials. The competition between recombination and dissociation of this interfacial state limits the generation of fully separated free charges. Therefore, a detailed understanding of the CT states is critical for building a comprehensive picture of t

As distributed systems continue to evolve, automatic resource management is becoming more and more impor tant. The resource management system must be able to dynamically handle large heterogeneous systems in a way that gives good performanceand resource utilization. In the performance context, allocating software modules to nodes in an efficient way is of high interest. This paper considers the pr

This review discusses the complicated two-electron dynamics of a helium atom in an intense, short laser pulse. A helium gas in femtosecond laser pulses at long wave lengths (lambda similar to 700 nm) and high intensities (I similar to 10(15) W/cm(2)) produces surprisingly high numbers of He2+ ions. These laser fields cause large and fast electron oscillations, which makes a solution of the time-de

We describe a novel method for determining weak association constants of oligomeric protein complexes formed transiently under equilibrium conditions. This type of equilibrium process is recognized as being biologically important, but generally hard to study. Heteronuclear spin relaxation rates measured at multiple protein concentrations are analyzed using relaxation rates predicted from hydrodyna

By exposing photosystem II (PSII) samples to an incrementing number of excitation flashes at room temperature, followed by freezing, we could compare the Mn-derived multiline EPR signal from the S-2 oxidation state as prepared by 1, 5, 10, and 25 flashes of light. While the S-2 multiline signals exhibited by these samples differed very little in spectral shape, a significant increase of the relaxa

Purpose. To investigate the structural development of the colloid phases generated during lipolysis of a lipid-based formulation in an in vitro lipolysis model, which simulates digestion in the small intestine. Materials and Methods. Small-Angle X-Ray scattering (SAXS) coupled with the in vitro lipolysis model which accurately reproduces the solubilizing environment in the gastrointestinal tract a

Aromatic side chains are attractive probes of protein dynamic, since they are often key residues in enzyme active sites and protein binding sites. Dynamic processes on microsecond to millisecond timescales can be studied by relaxation dispersion experiments that attenuate conformational exchange contributions to the transverse relaxation rate by varying the refocusing frequency of applied radio-fr
