Further insight in the web consolidation process - Part III. Modelling of paper shrinkage

A model for the web consolidation process in the paper dryer is developed and compared with experimental data for the kraft pulps. The model contains one parameter called the shrinkage factor which is used as the fitting parameter to the experimental data. The shrinkage factor can have a value between zero implying no shrinkage and a value of one which implies that all the liquid volume removed le

Origin invariant calculation of optical rotation without recourse to London orbitals

We propose an inherently origin invariant formulation of specific optical rotation obtained from the conventional velocity gauge expression by subtracting the static limit from the electric dipole-magnetic dipole polarizability: (omega) --> (omega) - (0). London (gauge including) atomic orbitals are therefore not needed to ensure origin invariance and, consequently, this modified velocity gauge fo

Pluggable checking and inferencing of nonnull types for Java

We have implemented a non-null type checker for Java and a new non-null inferencing algorithm for analyzing legacy code. The tools are modular extensions to the JastAdd extensible Java compiler, illustrating how pluggable type systems can be achieved. The resulting implementation is compact, less than 230 lines of code for the non-null checker and 460 for the inferencer. Non-null checking is a loc

Direct electrochemical oxidation of DNA on polycrystalline gold electrodes

Electrochemical CV and SWV studies were performed with double stranded DNA from salmon testes (dsDNA) and single stranded DNAs, containing 25 nucleotides (ssDNA) directly adsorbed at polycrystalline An electrodes. A distinct oxidation peak at + 730 mV (SWV, scan rate 0.248 V s(-1)) or at + 730 - + 780 mV (CV, scan rate from 0.3 to 1 V s(-1)) was obtained with DNA-modified Au electrodes after a tim

Simulation of chromatographic processes applied to separation of proteins

The advantages of using a detailed mathematical model for fixed bed chromatography is demonstrated by the personal computer program SIMCHROM. The chromatography model includes axial dispersion in the bulk liquid, external and internal mass transfer resistances and an instationary non-linear adsorption model. Frontal and pulse chromatography can be studied for single and multicomponent systems. The

Lack of association between plasma homocysteine levels and microangiopathy in type 1 diabetes mellitus

The reactive vascular-injuring amino acid homocysteine was previously shown to be increased in plasma in diabetic patients with clinical signs of nephropathy. In this study, plasma homocysteine was measured in type 1 diabetic patients with normoalbuminuria (n = 22), microalbuminuria (n = 40) and proteinuria (n = 14) in order to investigate whether plasma homocysteine levels are increased already a

Circulating soluble E-selectin in early rheumatoid arthritis: a prospective five year study

Background: Soluble E-selectin (sE-selectin) is a marker of activation of vascular endothelium. Objective: To examine serum levels of sE-selectin in a cohort of 85 patients with early rheumatoid arthritis (RA) followed up for five years. Methods: sE-selectin levels were assessed annually using an enzyme linked immunosorbent assay (ELISA) and related to simultaneously obtained clinical and laborato

2-Bromoethyl glycosides for synthesis of glycoconjugates on solid support

2-Bromoethyl glycosides can easily and in high yields be transformed into sulfones by treatment with a suitable thiol followed by oxidation with mCPBA. The observation that the so formed sulfones were cleaved by treatment with NaOMe/MeOH was used to design a new safety catch linker for synthesis of glycoconjugates on solid support.

Reliability and responsiveness of elbow trajectory tracking in chronic poststroke hemiparesis

This study established the reliability of a novel upper-limb trajectory-tracking task for assessment of perceptual motor control in hemiparetic adults. Eleven persons with chronic poststroke hemiparesis (mean 58.6 months) and eleven nondisabled control subjects performed an elbow flexion-extension task against a low-resistance isotonic load at three speeds: 25degrees/s, 45degrees/s, and 65degrees/

The effects of small roundabouts on emissions and fuel consumption: a case study

The effects of small roundabouts on emissions and fuel consumption were evaluated using the “car-following” method in a before/after study. The results showed that at a roundabout replacing a signalised junction, CO emissions decreased by 29%, NOx emissions by 21%, and fuel consumption by 28%. At roundabouts, replacing yield regulated junctions, CO emissions increased on average by 4%, NOx emissio

Six X-linked agammaglobulinemia-causing missense mutations in the src homology 2 domain of Bruton's tyrosine kinase: Phosphotyrosine-binding and circular dichroism analysis

Src homology 2 (SH2) domains recognize phosphotyrosine (pY)-containing sequences and thereby mediate their association to ligands. Bruton's tyrosine kinase (Btk) is a cytoplasmic protein tyrosine kinase, in which mutations cause a hereditary immunodeficiency disease, X-linked agammaglobulinemia (XLA). Mutations have been found in all Btk domains, including SH2, We have analyzed the structural and

Embodied Rituals and Ritualized Bodies : Tracing Ritual Practices in Late Mesolithic Burials

This thesis explores the ritual dimensions of the mortuary practices in the late Mesolithic cemeteries at Skateholm in Southern Sweden and Vedbæk-Bøgebakken in Eastern Denmark. With a combination of methods and theories that all focus on the ritual practices as action, a new approach to burials in archaeology is proposed. Special attention is given to the treatment of the body after death, which i

"Institutions", What Is In a Word? A Critique of the New Institutional Economics

This thesis is a critique of the New Institutional Economics (NIE) in economic history. The focus is on explanations to the origin and development of capitalist institutions within NIE. After a methodological discussion in chapter 1 the author investigates into how well NIE succeeds in explaining capitalist institutions. In chapters 2 and 3, a conceptual critique of the theoretical bases of evolu
