A highly functionalized six-membered cyclic carbonate, methacrylated trimethylolpropane (TMP) cyclic carbonate, which can be used as a potential monomer for bisphenol-free polycarbonates and isocyanate-free polyurethanes, was synthesized by two steps transesterifications catalyzed by immobilized Candida antarctica lipase B, Novozym®435 (N435) followed by thermal cyclization. TMP was functionalized

Electromagnetic scattering by a bounded object located inside a parallel plate waveguide is the subject of this paper. The exciting field in the waveguide is either an arbitrary source located at a finite distance from the obstacle or a plane wave generated in the far zone. The analytic treatment of the problem relies on an extension of the null field approach or Tmatrix method.

The fillet of the gear tooth is highly stressed in operation; so for heavily loaded gears, the fillet geometry must be controlled. The manufacturer's task is to, within acceptable tolerances, produce the gear to the designer's specifications regardless of the manufacturing method. Most often gear cutting tools are used that work under generating conditions. The tool will form the gear tooth; so to

The paper is concerned with heat integration of a conceptual hydrogen plant connected with a sugar factory. The sugar factory serves as a source of sucrose-containing thick juice for the hydrogen plant, where this feedstock is processed to hydrogen. Moreover, this connection gives an opportunity to utilize waste heat from the sugar factory. Hydrogen is produced by two-stage fermentation, that is,

Rheumatoid arthritis (RA) is a systemic disease, with an increased risk of co-morbidity from cardiovascular disease (CVD), in particular among those with severe disease. Environmental risk factors are of potential interest for both prevention and treatment of RA. Our aim was to examine changes in the occurrence of CVD over time and, using immunohistochemistry, study markers of inflammation in vas

Purpose: To characterize the clinical phenotype regarding retinal function and macular appearance in patients with spinocerebellar ataxia type 7 (SCA 7), with an emphasis on electrophysiological findings. Methods: Three patients from two Swedish families were given an ophthalmological examination including visual acuity, fundus inspection, Farnsworth's color vision test, Goldmann perimetry, full-f

In recent years, smog has become one of greatest challenges in China and many other countries. However, there are limited attentions of measuring public environment awareness of air pollution and the relations between public environmental awareness and smog prevention in a Chinese context. This study was designed to investigate the facts of public environmental awareness in a typical city of China

Geometry-based stochastic channel models (GSCMs) are extended to support multi-link simulations by applying the concept of common clusters. This novel approach aims to control the correlation between different links, inter-link correlation, by adjusting the amount of power simultaneously propagating via the same clusters in the different links. The behavior of common clusters is analyzed based on

Inflammatory processes have previously been shown to influence cognition and progression of dementia. An involvement of interleukin (IL)-6 has in particular been suggested as altered levels of IL-6 in cerebrospinal fluid (CSF) have been found in patients with Alzheimer's disease (AD). Also, an association between cognitive decline and levels of IL-6 in CSF have been reported. The aim of the presen

Economic crises directly and indirectly affect the financial health of museums. Despite this reality, however, analysing the impact of the economic cycle on museums has not generated much interest among researchers; to date published studies on the recent financial crisis and its reverberations in the museum sector are rare. This article, after acknowledging this lack of research, discusses specif

The ability of chondroitin/dermatan sulfate (CS/DS) to convey biological information is enriched by the presence of iduronic acid. DS-epimerases 1 and 2 (DS-epi1 and 2), in conjunction with DS-4-O-sulfotransferase 1, are the enzymes responsible for iduronic acid biosynthesis and will be the major focus of this review. CS/DS proteoglycans (CS/DS-PGs) are ubiquitously found in connective tissues, ba

Partial migration is a common phenomenon among many animals and occurs in many types of ecosystems. Understanding the mechanisms behind partial migration is of major importance for the understanding of population dynamics and, eventually, ecosystem processes. We studied the effects of food availability on the seasonal partial migration of cyprinid fish from a lake to connected streams during winte

The objectives of the study were to compare antibody response in immunosuppressed patients with rheumatoid arthritis (RA) after vaccination with heptavalent pneumococcal conjugate vaccine (PCV7) to that of RA patients and healthy controls vaccinated with 23-valent polysaccharide vaccine (PPV23) and to study the impact of disease and/or treatment characteristics and type of vaccine on antibody resp

In this paper we introduce and study a certain intricate Cantor-like set C contained in unit interval. Our main result is to show that the set C itself, as well as the set of dissipative points within C, both have Hausdorff dimension equal to 1. The proof uses the transience of a certain non-symmetric Cauchy-type random walk.

We have studied the (0001) surface termination of Rh2O3 on a Rh(111) single crystal using a combination of high resolution core level spectroscopy, low energy electron diffraction, scanning tunneling microscopy and density functional theory. By exposing the Rh(111) to atomic oxygen we are able to grow Rh2O3 layers exposing the (0001) surface. The experiments support the theoretical predictions sta

This paper presents two class-C CMOS VCOs with a dynamic bias of the core transistors, which maximizes the oscillation amplitude without compromising the robustness of the oscillation start-up, thereby breaking the most severe trade-off in the original class-C topology. An analysis of several different oscillators, starting with the common class-B architecture and arriving to the proposed class-C

Tubes form the basic structure of several organs like lungs, kidneys, glandular organs like the pancreas, mammary and salivary glands. Tube formation involves a series of dynamic and interdependent cellular processes, including cytoskeletal reorganization, assembly of intercellular junctional complexes, and cell polarization. Understanding how cells polarize and coordinate tubulogenesis during org

Den här artikeln för fram digitaliseringen och konsekvenserna av Internet som ett studieobjekt med inneboende möjligheter för metodutveckling inom rättssociologi och den bredare rättsvetenskapen – vilket i sin tur adresserar en teoretisk potential. Artikeln lyfter fram tre aspekter som det argumenteras för är av särskild vikt att adressera: 1.) de stora datamängdernas och mätbarhetens metodologisk

I såväl media som inom myndigheter och organisationer har det under de senaste åren i allt högre grad uppmärksammats att migrerande arbetskraft inom jordbruket/den gröna näringen eventuellt används på ett sätt som kan strida mot arbetsrättsliga och sociala regleringar.Avsikten med föreliggande studie är framförallt att sammanställa den forskning som finns avseende olika arbetslivs- och arbetsmiljö
