Polyurethanes and polycarbonates are widely used in a variety of applications including engineering, optical devices, and high-performance adhesives and coatings, etc., and are expected to find use also in the biomedical field owing to their biocompatibility and low toxicity. However, these polymers are currently produced using hazardous phosgene and isocyanates, which are derived from the reactio

The normal Auger electron spectrum of the O-2 molecule is assigned in detail on the basis of ab initio valence configuration interaction (CI) wavefunctions. Potential energy curves of the ground state, the core-ionized states and the doubly charged final states are calculated and Auger decay rates are obtained with the one-centre approximation. Using the lifetime vibrational interference method, b

Introduction. Examines how an analytical framework of situated genre analysis can be used to study how research blogs are constructed and used as tools in scholarly communication. Method. A framework was extracted from genre research theories consisting of four concepts: aim, form, content and context. The term situated genre was used to focus on social practices. The context was further elaborate

Purpose: The Purpose of this Study was to evaluate long-term outcomes of arthroscopic acromioplasty for shoulder impingement syndrome. Methods: This was a prospective cohort study of 31 shoulders (24 men) that underwent arthroscopic acromioplasty for shoulder impingement syndrome during 1992 and 1993. The mean age at surgery was 49 years (range, 33 to 68 years). A group of 29 shoulders (22 men) op

Bumblebee communities and their foraging resources were surveyed in south Swedish agricultural landscapes of contrasting complexity, defined by the size of arable fields and the amount of permanent grazed pastures. After the flowering of oilseed rape (OSR), simplified landscapes contained substantially less herbaceous flower resources and a lower proportion of perennials, compared to complex ones.

A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance. The modeling approach utilized the two-phase models involving water phase change for PEM fuel cells i.e. two-phase curr

Environmental levels of airborne carcinogenic and related substances are comparatively better known than individual exposure and its determinants. We report on a personal monitoring program involving five Swedish urban populations. The aim of the program was to investigate personal exposure to benzene, 1,3-butadiene, formaldehyde, and nitrogen dioxide (NO2). The measurements were performed among 4

Alkaline sphingomyelinase (NPP7) is an ecto-enzyme expressed in intestinal mucosa, which hydrolyses sphingomyelin (SM) to ceramide and inactivates platelet activating factor. It is also expressed in human liver and released in the bile. The enzyme may have anti-tumour and anti-inflammatory effects in colon and its levels are decreased in patients with colon cancer and ulcerative colitis. Active NP

Aim: To explore how 12-year-old Swedish children experienced being involved in a coeliac disease (CD) screening. Methods: A qualitative approach was used to analyse short narratives written by children who had taken part in a school-based CD screening. Narratives were written after blood sampling, but prior to learning of the test results. Through an oscillation between the texts, codes, subcatego

We report on In0.63Ga0.37As FinFETs utilizing nanowires grown by selective-area growth as channel. These nanowires are defined by crystallographic planes rather than pattern transfer using etching. The fabricated devices exhibit maximum transconductance g(m,max) = 2.05 mS/um at V-ds = 0.5 V, as well as record-high extrapolated f(t) = 300 GHz and f(max) = 342 GHz, on the non-planar III-V MOSFET pla

Thermal spraying is a widely applied coating technique. The optimisation of the thermal spraying process with respect to temperature or temperature induced residual stress states requires a numerical framework for the simulation of the coating itself as well as of the quenching procedure after the application of additional material. This work presents a finite element framework for the simulation

We consider several simple combinatorial problems and discuss different ways to express them using polynomial equations and try to describe the Gröbner basis of the corresponding ideals. The main instruments are complete symmetric polynomials that help to express different conditions in rather compact way.

From an interdisciplinary approach, this study aims at analyzing self-reported animal fear, specifically large carnivore fear, in relation to public willingness to pay to fulfill a governmental policy on large carnivore-induced costs. In a survey in Sweden involving more than 2,000 respondents, it was found that people whose animal fear was directed particularly toward large carnivores were less l

This dissertation is the first academic treatment and systematic analysis on the theology of Bishop Ding Guangxun (K.H. Ding) who is an internationally- renowned Christian leader of the Chinese Protestant Church in contemporary China. It seeks to explore the development of Bishop Ding’s contextual theology with special emphasis on his political theology of accommodation and cultural indigenization

The objective of the study was to assess sense of coherence (SOC) many years after traumatic brain injury (TBI) and explore the relationship between SOC and self-rated life satisfaction (LS) as well as measures of functioning and disability, sex, age at injury, injury severity and time post-injury. Sixty-six individuals (aged 18-65 years) who were 6-15 years post-injury were interviewed. Data on S

The role of inorganic pyrophosphate (PPi) as an energy carrier in the central metabolism of the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus was investigated. In agreement with its annotated genome sequence, cell extracts were shown to exhibit PPi-dependent phosphofructokinase and pyruvate phosphate dikinase activity. In addition, membrane-bound pyrophosphatase activity wa
