Morphologies and droplet sizes of alkyd-acrylic hybrids with high solids content

Alkyd-acrylic hybrids having final solids content of 75-80% were prepared by dropping alkyd resin into an acrylic dispersion. The resulting suspo emulsion structures and the alkyd droplet sizes in the hybrids were dependent on the preparation procedure as well as the interfacial tension between the two liquid phases, sigma(12), the shear rate, gamma, the latex/alkyd ratio and the viscosity ratio,

Epitope spreading and autoimmune glomerulonephritis in rats induced by a T cell epitope of Goodpasture's antigen

An amino-terminal region of a, chain of type IV collagen noncollagenous domain [alpha(3)(IV)NC1] that induces experimental autoimmune glomerulortephritis (EAG) in rats has been identified. Only recombinant antigens that contain a nine-amino acid (AA) span of alpha(3)(IV)NC1, consistent with a T cell epitope, could induce EAG. It was hypothesized that synthetic peptides of this region should induce

Influence of the consumption of fatty Baltic Sea fish on plasma levels of halogenated environmental contaminants in Latvian and Swedish men

We examined the influence of widely varied consumption of fatty fish from the Baltic Sea and of age on plasma concentrations of polychlorinated biphenyls (PCBs), polychlorobiphenylols (OH-PCBs), 2, 2-bis(4-chlorophenyl)-1,1,1-trichloroethane (4,4'-DDT), 2, 2-bis(4-chlorophenyl)-1,1-dichloroethane (4,4'-DDE), 2,2',4, 4'-tetrabromodiphenyl ether (BDE-47), hexachlorobenzene (HCB), and pentachlorophen

En text är en text är en text? Om en terminologisk tredelning av textbegreppet

Ett terminologisk förslag till tredelning av textbegreppet i första hand ägnat att handha texttraditioner som rymmer större eller mindre variation: textverk = den abstrakta storhet som i olika manifestationer uppfattas som ett och samma verk (ett slags motsvarighet till fonemet), textvittne = den specifika manifestationen av ett textverk, textbärare = den konkreta (och därmed multimodala) bäraren

Detection of duplicate defect reports using natural language processing

Defect reports are generated from various testing and development activities in software engineering. Some-times two reports are submitted that describe the same problem, leading to duplicate reports. These reports are mostly written in structured natural language, and as such, it is hard to compare two reports for similarity with formal methods. In order to identify duplicates, we investigate usi

Creep Recovery and Elastic Modulus of High Performance Concrete

This article outlines an experimental and numerical study on short-term and long-term creep recovery in High Performance Concrete. About 200 cylinders and 800 cubes were tested. The ambient climate was held constant at 20 °C and 55% relative humidity. Results and analyses are presented as regards short-term and long-term creep recovery with some related properties. The creep deformations are separ

Fatty-acid-displaced transcriptional repressor, a conserved regulator of cytochrome P450 102 transcription in Bacillus species

Bacillus subtilis strain 168 encodes two flavocytochromes P450, Cyp102A2 and Cyp102A3. The cyp102A3 gene is preceded by, and organized in an operon with, a gene for a transcriptional regulator, encoded by fatR. The paralogous gene, cyp102A2, is most likely transcribed as a mono-cistronic message. We show that fatR encodes a protein that binds to an operator sequence that is present upstream of its

Mitogenic effects of ATP on vascular smooth muscle cells vs. other growth factors and sympathetic cotransmitters

The sympathetic nervous system has been shown to exert a trophic influence on vascular smooth muscle cells (VSMC). Therefore, we studied the growth-regulating effects of the sympathetic cotransmitters ATP, neuropeptide Y (NPY), and norepinephrine (NE). ATP in concentrations of 1-100 microM greatly increased the incorporation of [3H]thymidine in VSMC from rat aorta and vena cava. ATP also increased

Animism, fetishism, and objectivism as strategies for knowing (or not knowing) the world

Animistic or 'relational' ontologies encountered in non-Western (i.e. premodern) settings pose a challenge to Western (i.e. modern) knowledge production, as they violate fundamentalassumptions of Cartesian science. Naturalscientists who have tried seriously to incorporate subject-subject relations into their intellectual practice (e.g. Uexküll, Bateson) have inexorably been relegated to the margin

The role of context and inhibition in ADHD.

We have shown in a computational model that a poor memory for context could result in some of the behaviors associated with ADHD, which is well in line with the dynamic developmental theory. Given the important role of context in extinction, a weaker context due to a steeper delay-of-reinforcement gradient would result in impaired inhibition.
