In the water-oxidizing reactions of photosystem II (PSII), a tyrosine residue plays a key part as an intermediate electron-transfer reactant between the primary donor chlorophylls (the pigment P-680) and the water-oxidizing Mn cluster. The tyrosine is deprotonated upon oxidation, and the coupling between the proton reaction and electron transfer is of great mechanistic importance for the understan
The entity sinusitis, bronchiectasis, and situs inversus is since long named Kartagener syndrome. Nowadays the designation used is primary ciliary dyskinesia (PCD), which implies cilia with decreased or total absence of motility, which may result in sinusitis, chronic bronchitis, bronchiectasis, and male infertility. A large number of deficiencies detectable on the ultrastructural level give rise
Thymus colonisation and thymocyte positioning are regulated by interactions between CCR7 and CCR9, and their respective ligands, CCL19/CCL21 and CCL25. The ligands of CCR7 and CCR9 also interact with the atypical receptor CCRL1 (also known as ACKR4), which is expressed in the thymus and has recently been reported to play an important role in normal alpha beta T-cell development. Here, we show that
Asperger syndrome (AS) and non-verbal learning disability (NLD) are both characterized by impairments in motor coordination, visuo-perceptual abilities, pragmatics and comprehension of language and social understanding. NLD is also defined as a learning disorder affecting functions in the right cerebral hemisphere. The present study investigates if individuals with AS and a cognitive profile consi
Aerococcus is a genus that comprises seven species, of which Aerococcus urinae, and Aerococcus sanguinicola are emerging human pathogens. Aerococci are gram positive cocci that are easily misidentified as streptococci or staphylococci, and thus the incidence of aerococcal infections has been underestimated. With the introduction of matrix-assisted laser desorption ionization time-of-flight mass sp
Protein–protein interactions play important roles in bacterial pathogenesis. Surface-bound or secreted bacterial proteins are key in mediating bacterial virulence. Thus, these factors are of high importance to study in order to elucidate the molecular mechanisms behind bacterial pathogenesis. Here, we present a protein-based strategy that can be used to identify and isolate bacterial proteins of i
The classification of 2 532 new settlements in the Census of India 2011 as 'urban', and specifically as 'Census Towns', has brought small and emerging urban centres back into the purview of urban studies and urban development in India. Taking this to be a point of entry, this article seeks to explore how the urban has been framed and approached from different and competing epistemological standpoi
A comprehensive, three-dimensional model of a proton exchange membrane (PEM) fuel cell based on a steady state code has been developed. The model is validated and further be applied to investigate the effects of various porosity of the gas diffusion layer (GDL) below channel land areas, on thermal diffusivity, temperature distribution, oxygen diffusion coefficient, oxygen concentration, activation
Drop fragmentation in high intensity turbulent emulsification processing equipment-such as rotor-stator mixers (RSMs)-has traditionally been described in terms of a stress balance; between the stabilizing stress of the drop and the time-averaged turbulent stress at the most intense position of the flow. As shown in part 1 of this series, this approach is often a fruitful first approximation. Howev
Under de senaste två decennierna har sexualbrottslagstiftningen, som återfinns i brottsbalkens sjätte kapitel, genomgått flera omfattande reformer. Flera av dessa har syftat till att skärpa straffansvaret vid sexualbrott på distans. Vid genomförda reformer har lagstiftarens syfte alltjämt varit att skifta fokus från de sexuella handlingarnas tekniska karaktär till kränkningen som sådan vid avgräns
Sammanfattning Förtroendet för samhällsinstitutioner har genom historien varit avgörande för deras bestående. I utvecklade samhällen som Sverige behöver medborgarna förlita sig på att lagföringen görs korrekt. Förtroendet är i sin tur avgörande för att människor rättar sig efter domar och beslut. Tydlig kommunikation är vidare ett krav för att tilliten till domstolarna ska kunna byggas samt stärka
Köttkonsumtionen ökar hela tiden och bidrar till en negativ klimatpåverkan. Detta på grund av de växthusgaser som köttindustrin medför. Att äta en mer växtbaserad kost kan ha en effektfull inverkan på minskandet av dessa växthusgaser. Sverige är ett av de länder som är sämst på att äta baljväxter, då vi mer eller mindre enbart äter ärtsoppa och bruna bönor med fläsk, när det kommer till baljväxterMeat consumption keeps increasing, which in time, contributes to a negative climate impact due to the greenhouse gases that the meat industry causes. Eating a more plant-based diet can have a direct impact on the reduction of these greenhouse gases. Sweden is one of the countries were its people stick to a minimum number of legumes in their diet, as they only eat it in everyday meals like pea so
The possibility to have a strongly first order electroweak phase transition, which is one of the Sakharov conditions for electroweak baryogenesis together with $\mathcal{CP}$ violation and baryon number violation, in general Two-Higgs-Doublet Models (2HDMs) is here investigated. Different kinds of $\mathbb{Z}_{2}$ breaking beyond standard assumptions are studied, in particular by allowing it to be
The purpose of this study was to investigate the applicability of data-driven experimental design for the optimization of a hard coating for cutting tools in metal machining. The complexity of metal machining leads to difficulty in theoretically modeling and understanding the interactions and correlations between parameters and performance. Because of this and the importance of incremental perform
