The effects of thermal annealing on the viscoelastic properties and morphology of films prepared from bimodal latex blends containing equal weight fractions of soft and hard latex particles with controlled sizes were investigated. The thermal and viscoelastic properties of as-dried and annealed samples were investigated with differential scanning calorimetry and dynamic mechanical analysis (DMA).

After emigrating from England to Canada in the late 1970s, Robin Wood gained wide recognition as a major “Canadian” film critic, but he was criticized by some for his luke-warm response to the cinema of his adopted country. That response can be traced, in part, to the influence of the English literary critic F.R. Levis, but also to intellectual trends and cultural preferences Wood shared with othe

Preface. The RILEM Committee TC-117 FDC -Freeze-Thaw and De-icing Resistance of Concrete:-started its workwith a first meeting that was hel d in Essen in May 1990. A second meeting was held in Brighton in November the same year. During both meetings, some differences in opinion were disc10sed concerning the effects of different externai and internai factors on the de-icing resistance and concernin

This study aimed to investigate if there is an association between bacterial vaginosis (BV) and smoking. This cohort study included 956 randomly chosen, apparently healthy women at 2 family planning and one youth clinic. Of the 956 women, 131 women fulfilled the criteria for BV and the remaining 825 served as a control group. BV, BV-associated bacteria and gynaecological infections were diagnosed.

Cryocooled crystals of a mercury complex of Escherichia coli dUTPase diffract to atomic resolution. Data to 1.05 Å resolution were collected from a derivative crystal and the structure model was derived from a Fourier map with phases calculated from the coordinates of the Hg atom (one site per subunit of the trimeric enzyme) using the program ARP/wARP. After refinement with anisotropic temperature

The aim of this study was to develop an in-vitro release method suitable for injectable slow-release lipid formulations of local anaesthetics (or other drugs). We also aimed that the results of the in-vitro measurements should have a clear relationship to duration of action in-vivo. Six formulations of bupivacaine base in medium-chain triglyceride-glyceryl dilaurate mixtures were developed. A new

Popular Abstract in Swedish Fordons körmönster, dvs deras hastighets- och accelerationsprofiler, påverkar avgasutsläpp och bränsleförbrukning avsevärt. Detta projekt syftade till att undersöka körmönster i tätort genom att behandla följande delområden: 1) Hur kan körmönster mätas?, 2) Hur kan körmönster beskrivas? – dvs att finna mått för att karakterisera olika egenskaper hos körmönster., 3) Vad Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. This project was aimed at investigating urban driving patterns by focusing on the following issues: 1) how to measure driving patterns, 2) measures for the description of driving patterns, 3) identification of characteristics of driving patterns that have significant ef

Mouse mammary tumor virus (MMTV) has a proven role in breast carcinogenesis in wild mice and genetically susceptible laboratory inbred mice. The carcinogenic characteristics of this virus are enhanced by estrogen and other steroid hormones. MMTV-like envelope gene sequences, with 95% homology to MMTV have been identified in approximately 40% of breast cancers in US, Australian and Argentinian wome

We describe a fast and accurate collision-detection algorithm specialised for models deformed by morphing. The models considered are meshes where the vertex positions are convex combinations of sets of reference meshes. This new method is based on bounding-volume trees that are extended to support efficient tree-node updates by blending associated sets of reference bounding volumes. With our appro

In 1998, I estimated the number of birds killed on Swedish roads at about ten million. This estimate was ten times higher than a previous estimate from 1978. 1 suspected that the difference depended on different methods, and that my estimate was the most correct one. At that time I was not aware of a careful Danish study, which estimated the total road kill of birds at 3.3-3.5 million in that coun

Background. It has been previously demonstrated that addition of anti-LFA-1 to a combination of CTLA4Ig and anti-CD40L induces the permanent acceptance of dopaminergic fetal pig xenografts when transplanted into the brain of wild-type mice. The purpose of this study was to test whether this costimulation blockade also can induce acceptance of adult pig islets transplanted to C5713L/6 mice with str

Electronic and structural properties of GaAs(100)(2x4), InAs(100)(2x4), and Sb/InAs(100)(2x4) reconstructed surfaces have been studied by synchrotron-radiation photoelectron spectroscopy and scanning tunneling microscopy (STM). Based on the difference spectrum of As 3d core-level spectra of III-As(100)(2x4), measured in different surface-sensitivity conditions, as well as the line shape of the As

This report presents the derivation of a nonlinear model for the ETH helicopter laboratory process. The model is derived using Euler-Lagrange equations together with relations from propeller theory. The model is formulated as a state-space model, which enables straightforward implementation in standard simulation tools such as Simulink (TM). A set of model parameters computed from the ETH process

Adrenocorticotrophic hormone (ACTH) facilitates the synthesis of adrenal glucocorticoids by maintaining the enzymes that control the side-chain cleavage of cholesterol, the rate-limiting step in the biosynthesis of steroids 1]. Thus, ACTH is involved in the control of adrenal lipid metabolism. Recent studies have revealed that treatment with ACTH in pharmacological dosage also influences plasma li
