1. Studies of aquatic environments have shown that community organisation may strongly affect ecosystem functioning. One common phenomenon is a change in nutrient level following a shift in the fish community composition. Although several hypotheses have been suggested, there is no consensus on which mechanisms are involved. Our study evaluated indirect effects of benthivorous fish on the biogeoch
As reduction of sample complexity is a central issue in membrane proteomic research, the need for new pre-fractionation methods is significant. Here we present a method for fast and efficient enrichment of Escherichia coli inner membranes expressing a His-tagged integral membrane L-fucose-proton symporter (FucP). An enriched inner membrane fraction was obtained from a crude membrane mixture using
We present CHS, a computer program designed to calculate the condensation energy of the homogeneous superconducting electron gas. The correlation energy, which we treat at the level of the RPA, is an essential ingredient for the construction of a local density approximation in the framework of density functional theory for superconductors (SCDFT) [Kurth et al., Phys. Rev. Lett. 83 (1999) 2628].
Spectrographic graphite electrodes were modified through adsorption with laccase from Trametes versicolor. The laccase-modified graphite electrode was used as the working electrode in an amperometric flow-through cell for monitoring phenolic compounds in a single line flow injection system. The experimental conditions for bioelectrochemical determination of catechol were studied and optimized. The
The thalassaemia syndromes, endemic in the Mediterranean area, the Middle East, the Indian subcontinent, the Far East and in tropical Africa, are the most common hereditary disorders in humans, and millions of people are affected by diseases. Due to a widespread population flow between continents in recent past centuries, the thalassaemias are now occurring with relatively high frequency in many n
I focus on the distinction between sensation and perception. Perceptions contain additional information that is useful for interpreting sensations. Following Grush, I propose that emulators can be seen as containing (or creating) hidden variables that generate perceptions from sensations. Such hidden variables could be used to explain further cognitive phenomena, for example, causal reasoning.
Two approaches based on alkaline hydrolysis, in combination with either stir-bar sorptive extraction (SBSE) or sonication, were developed for the determination of banned azo dyes in bovine leather. All dyes were determined indirectly by measuring their corresponding harmful amines, formed after chemical reduction. Quantification was performed by employing standard addition methodology to compensat
BACKGROUND: Blockade of CD40 ligand (CD40L; CD154, gp39) is a potential treatment for autoimmune disease and allograft rejection. However, CD40L-/- mice are capable of mobilizing cellular immune responses to viral, parasitic, and intracellular bacterial infections as well as rejecting skin grafts with nearly the same efficiency as wild-type mice. CD40L-deficient mice (CD40L-/-) or wild-type mice t
Information on the first excited states in the N = Z = 41 nucleus Nb-82 sheds light on the competition of isospin T = 0 and T = 1 states in the A similar to 80 region. The measurement was performed at the GSI laboratory using fragmentation of a Ag-107 primary beam at 750 MeV/u on a 4 g/cm(2) Be-9 target. The fragments were separated and identified unambiguously in the FRagment Separator. Three exc
Having a child with a disability undoubtedly affects parents in many ways, including their well-being. However, the specific mental health trajectories of parents, differentiated by the severity of impairments and parental roles, remain under-explored. We investigate the mental-health effects of having a child with a disability. Using individual-level register data from Sweden, we exploit the epid
In this chapter, we evaluate how the concept of the entrepreneurial ecosystem - a systemic approach to regional economic development that is receiving increased attention from both policymakers and academics - can assist in analysing and understanding the informal economy. We argue that despite the focus of entrepreneurial ecosystems on high-growth entrepreneurship, the ‘systemic’ perspective of t
J. S. Wilson proved in 1971 an isomorphism between the structural lattice associated to a group belonging to his second class of groups with every proper quotient finite and the Boolean algebra of clopen subsets of Cantor’s ternary set. In this paper we generalize this isomorphism to the class of branch groups. Moreover, we show that for every faithful branch action of a group G on a spherically h
Being the most common of the upper extremity fractures, the distal radius fracture rightfully earns its attraction. In a global population rapidly growing older, the number of patients with a distal radius fracture will increase. Innovative devices have been developed in the last few decades to restore the anatomy. The well-trained surgeon has all the options to fix the majority of fractures in an
Esophageal lesions are common findings in disorders of the digestive tract in patients living with HIV, the most typical symptoms being odynophagia and/or dysphagia. This article provides a narrative review of the spectrum of esophagitis in patients living with HIV, focusing on fungal, viral, bacterial and non-infectious etiologies, as well as co-infections with viral hepatitis viruses. The articl
Introduction: The healthcare sector is globally experiencing increasing demands and workplace interventions on an organisational level is sought to create healthy workplaces. The aim of this study was to provide an overview of Nordic research on the work environment and health of healthcare professionals, with a focus on identifying organisational-level risk and health-promoting factors. Methods:
In electric passenger vehicles with modest performance the drivetrain usually consists of one inverter, one electrical machine and a single-speed transmission. The inverter is typically a two-level inverter using either Si IGBT transistors with an anti-parallel Si diode, or a SiC MOSFET transistor with or without an anti-parallel diode. The benefits of selecting SiC MOSFET as semiconductor technol
