Shifting the resource base for chemical production from fossil feedstocks to renewable raw materials provides exciting possibilities for the use of industrial biotechnology-based process tools. This review gives an indication of the current developments in the transition to bio-based production, with a focus on the production of chemicals, and points out some of the challenges that exist in the la
A new Certified Reference Material (CRM) for radionuclides in sediment (IAEA-385) is described and the results of the certification process are presented. Eleven radionuclides (K-40, Cs-137, Ra-226, Ra-228, Th-230, Th-232, U-234, U-238, Pu-238, Pu239+240 and Am-241) have been certified and information mass activities with 95% confidence intervals are given for seven other radionuclides (Sr-90, Pb-
In isolated conjugated polymers two explanations are in discussion for the redshift of the emission on a picosecond time scale-exciton energy transfer (EET) between conjugated segments along the chains and conformational changes of these segments themselves, i.e., torsional relaxation. In order to resolve this question we perform femtosecond time-resolved transient absorption measurements of the e
Background The summarized importance of haemostatic and metabolic variables (insulin, lipids including lipoprotein (a) [Lp(a)] and leptin) in predicting first myocardial infarction, as well as possible interactions among these variables, have not been reported. Design A prospective case-control study nested within the Northern Sweden Health and Disease Cohort. Methods Sixty-two men diagnosed with
Ruthenium complexes offer new perspectives in cancer therapy; towards this aim we have synthesized a new amphiphilic unimer able to coordinate ruthenium complexes and to form liposomes.
The von Willebrand Disease Prophylactic Network (vWD PN) has been initiated to study the natural history of vWD bleeding, and to prospectively study the role of von Willebrand Factor (vWF) concentrate prophylaxis in vWD. Patients with all types of vWD in need of treatment with vWF concentrate will be enrolled into the study. Quality of life will be measured and safety and efficacy will be monitore
Improved understanding of the importance of different surfaces in supporting attached nitrifying and denitrifying bacteria is essential if we are to optimize the N removal capacity of treatment wetlands. The aim of this study was therefore to examine the nitrifying and denitrifying capacity of different surfaces in a constructed treatment wetland and to assess the relative importance of these surf
Urbanisation is increasing worldwide, and there is now ample evidence of phenotypic changes in wild organisms in response to this novel environment. Yet, the genetic changes and genomic architecture underlying these adaptations are poorly understood. Here, we genotype 192 great tits (Parus major) from nine European cities, each paired with an adjacent rural site, to address this major knowledge ga
Two key challenges for governing and managing critical infrastructure risk and resilience are interdependencies between infrastructures and the multi-actor setting in which they operate. This paper looks beyond the Critical Infrastructure (CI) field of research to identify and discuss cross-disciplinary approaches to address these challenges. It explores two related and slightly overlapping resear
Unsatisfactory indoor air quality (IAQ) can result from emissions of volatile organic compounds from the materials of the building. A surface emissions trap (cTrap) can be used to stop such emissions thus preventing them from reaching the indoor air. The present study concerned an apartment where the tenants experienced skin and mucous membrane irritation due to moisture-driven emissions from the
We examine a two-dimensional Coulomb gas consisting of n identical repelling point charges at an arbitrary inverse temperature β, subjected to a suitable external field. We prove that the gas is effectively localized to a small neighbourhood of the droplet – the support of the equilibrium measure determined by the external field. More precisely, we prove that the distance between the droplet and t
Most commercial prosthetic hands lack closed-loop feedback, thus, a lot of research has been focusing on implementing sensory feedback systems to provide the user with sensory information during activities of daily living. This study evaluates the possibilities of using a microphone and electrotactile feedback to identify different textures. A condenser microphone was used as a sensor to detect th
Peptic Ulcer Disease (PUD) is the most common disorder of the stomach and duodenum, which is associated with Helicobacter pylori infection. PUD occurs due to an imbalance between offensive and defensive factors and Proton Pump Inhibitors (PPI), Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) and antibiotics are frequently used for the treatment. Recently, medicinal plants have emerged as efficacious
INTRODUCTION: Autoimmune disorders have become increasingly acknowledged as having a more causative role in encephalitis than previously assumed. Anti-N-methyl-D-aspartate receptor encephalitis seems to be the most prevalent disorder. Symptoms of the neuropsychiatric phase in children and adolescents include abnormal behavior, seizures, and neurologic symptoms. We present a report on a teenage gir
One important step in binary modeling of environmental problems is the generation of absence-datasets that are traditionally generated by random sampling and can undermine the quality of outputs. To solve this problem, this study develops the Absence Point Generation (APG) toolbox which is a Python-based ArcGIS toolbox for automated construction of absence-datasets for geospatial studies. The APG
