The present work reports on the development of a bi-enzyme biosensor using diaphorase from Bacillus stearothermophilus, nicotinamide adenine dinucleotide (NAD(+))- and glutathione (GSH)-dependent formaldehyde dehydrogenase (FDH) from the genetically-engineered methylotrophic yeast Hansenula polymorpha as bio-recognition elements. The sensor architecture comprises a first layer containing diaphoras
The effects of the physical-spatial-technical environment on aging well have been overlooked both conceptually and empirically. In the spirit of M. Powell Lawton's seminal work on aging and environment, this article attempts to rectify this situation by suggesting a new model of how older people interact with their environment. Goals of the paper include (a) integration of the essential elements o
Cerebral small vessel disease (SVD) is a common accompaniment of ageing. Features seen on neuroimaging include recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy. SVD can present as a stroke or cognitive decline, or can have few or no symptoms. SVD frequently coexists with neurodegenerative disease, and can exacerbate cogn
Purpose – The aim of this study is to test the assumption that ability to handle communication and liability of newness (LoN) is enhanced by academic entrepreneurship education and/or previous start‐up experience. Design/methodology/approach – The data collection includes a questionnaire with a total sample of 392 responding entrepreneurs in Sweden. Statistical analyses are made between entrepren
Human aquaporin 2 (AQP2) is a water channel found in the kidney collecting duct, where it plays a key role in concentrating urine. Water reabsorption is regulated by AQP2 trafficking between intracellular storage vesicles and the apical membrane. This process is tightly controlled by the pituitary hormone arginine vasopressin and defective trafficking results in nephrogenic diabetes insipidus (NDI
Reactions of cis-[PtCl(NH3)(CyNH2)(OH2)](+) (Cy = cyclohexyl) with thione-containing single-stranded oligonucleotides d(T8XT8) and d(XT16) (X = I-s6 or U-s4) and the mononucleotides 4-thiouridine ((UMP)-U-s4) and 6-mercaptoinosine ((IMP)-I-s6) have been studied in aqueous solution at pH 4.1. The reaction kinetics was followed using HPLC methodology as a function of ionic strength in the interval 5
Thoracic cirripedes are sessile crustaceans that use six pairs of thoracic appendages (the cirri) to catch and handle food. We used scanning electron microscopy to examine the cirri, which include one to three pairs of maxillipeds in six species of thoracican barnacles, in search of correlations between cirral setation and feeding mode. The species studied comprise both pedunculate and sessile for
Background: While the association between increased maternal age and congenital disorders has long been recognized, the offspring of older fathers are also at increased risk of congenital disorders related to DNA errors during spermatogenesis. Recent studies have drawn attention to an association between increased paternal age and increased risk of schizophrenia. The aim of the current study was t
This article presents two new models that give a perspective on green chemistry (GC). The first model is a classification model of different green chemistry activities, while the second model concerns green chemistry policy and knowledge areas (green chemistry principles, industrial biotechnology and "the green sector"). A broad view of green chemistry is used, where all activities with the aim of
Release of cytotoxic granule proteins from activated eosinophil granules is considered to be a key pathogenic mechanism in eosinophilic diseases. Degenerated eosinophils and extracellular eosinophil granules have been repeatedly depicted. The present overview describes evidence that eosinophil lysis and distribution of free eosinophil granules (as opposed to 'classical degranulation') is an import
The human rights regime and the trade regime set obligations on states that may create conflicts that challenge a state’s autonomy for policy and regulatory practices. To deal with these conflicts, we argue that states employ different causal mechanisms from Risse, Ropp and Sikkink’s spiral model when setting their commitments to, and executing compliance with, these regime obligations, and that t
The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions
This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. First, the stray-light suppression method Periodic Shadowing (PS) is implemented in an experimental setup with a high-power high repetition rate laser syste
We studied bacterial and fungal colonization of submerged plant litter, using a known Si-accumulator (Equisetum arvense), in experimental microcosms during one month. We specifically addressed the microbial decomposer role concerning biogenic silica (bSiO2) dissolution from the degrading litter. To vary the rates and level of microbial colonization, the litter was combined with a range of mineral
We present a Bayesian ideal observer model that estimates observer translation and rotation from optic flow and an extra-retinal eye movement signal. The model assumes a rigid environment and noise in velocity measurements, and that eye movement provides a probabilistic cue for rotation. The model can simulate human heading perception across a range of conditions, including: translation with simul
The industrial sector of Sweden used 136 TWh of energy 2022 out of which the agricultural sector used 6.09 TWh. The goal of the country is to become 50% more energy efficient by 2030 compared to 2005. Furthermore, Sweden’s long-term target is to achieve net zero greenhouse gas emissions by 2045. From 2005-2022 the total energy use of the agricultural sector has been reduced by 16% but previous stu
Fourier transform infrared spectroscopy techniques were used to study the kinetics of gas-phase reactions of three lactones, γ-valerolactone (GVL), 2(5H)-furanone (2(5HF) and 3-methyl-2(5H)-furanone (3M2(5H)F) with Cl atoms, OH radicals and O3 respectively. The experiments were performed in a photochemical reactor at a total pressure of 700 Torr at room temperature (298±2 K). Both relative rate an
Through a case study of H&Ms equestrian sponsorship this study aims to investigate the communicative aspects of sports sponsorships targeting a young audience, as well as its impact on the core values of children’s and youth sports in the Swedish society. Furthermore, this study intends to investigate and create further knowledge on how elite athletes are used by commercial businesses in order
