Photoactivation of photosystem II has been studied in the FUD 39 mutant of Chlamydomonas reinhardtii that lacks the 23 kDa extrinsic subunit of photosystem II. We have taken advantage of the slow photoactivation rate of FUD 39, earlier demonstrated in Rova, E. M., et al. [(1996) J. Biol. Chem. 271, 28918-28924], to study events in photosystem II during intermediate stages of the process. By measur

A method was developed for the determination of benzene in urine. The sample was pumped through the donor channel of a membrane extraction unit with a micro-porous membrane, separating the donor channel from an identical acceptor channel purged with nitrogen. The analyte reached the acceptor channel by diffusion through the membrane and was then swept by the carrier to a solid sorbent tube, where

The flora of 17 islets was studied during the period 1968-2000, with thorough inventories from 1971. At each visit the species present and their population sizes were noted. The flora of the smallest islets of hard rock consisted mainly of perennials, and remained unchanged in terms of species present throughout the period of study. In the larger and more complex islets the major part of the flora

Alkyl glycosides are surfactants with good biodegradability and low toxicity, attractive to produce by an enzymatic method to get a well-defined product. In this paper, we report a novel thermostable variant of a family 3 β-glucosidase to be an efficient catalyst in alkyl-glucoside forming reactions using transglycosylation with hexanol or octanol as the acceptor molecule. The enzyme has an appare

The mechanism of the reaction of ketene with hydroxyl radical has been studied by ab initio CCSD(T)-F12/cc-pVQZ-F12//B3LYP/6-311G(d,p) calculations of the potential energy surface. Temperature- and pressure-dependent reaction rate constants have been computed using the RRKM-Master Equation and transition state theory methods in the temperature range of 300–3000 K and in the pressure range of 0.01–

This article aims to enable a conversation between cosmopolitan thought, with focus on individual ethical experiences and reflections, and research on embodied military experiences. While we derive our ethical reasoning from cosmopolitanism, we concede that it lacks sensitivity to individuals’ other-regarding reflections and acts. Moreover, it does not sufficiently problematize the ways in which c

Economic history has recently emphasised the impact of economic shrinking on long-term economic growth, but economic theories do not provide explanations for how and why some countries avoid economic shrinking. In this case study of institutional change in post-independence Indonesia, we examine how the country managed to reduce the frequency of shrinking during the authoritarian regime and beyond

Satellite remote sensing of plant phenology provides an important indicator of climate change. However, start of the growing season (SOS) estimates in Northern Hemisphere boreal forest areas are known to be challenged by the presence of seasonal snow cover and limited seasonality in the greenness signal for evergreen needleleaf forests, which can both bias and impede trend estimates of SOS. The ne

During the past few decades systemic corruption has come to be seen as a significant factor which hinders socio-economic development, posing a serious threat to the political, economic and social well-being of many developing and transition countries. Under conditions of systemic corruption, many institutions, rules and norms of behaviour have become adapted to a corrupt modus operandi. Public off

With the present demand on fast and inexpensive aerosol source apportionment methods, the Aethalometer model was evaluated for a full seasonal cycle (June 2014–June 2015) at a rural atmospheric measurement station in southern Sweden by using radiocarbon and levoglucosan measurements. By utilizing differences in absorption of UV and IR, the Aethalometer model apportions carbon mass into wood burnin

This paper reports a numerical investigation on the effect of cavity geometry on fuel transport and mixing processes in a scramjet combustor with a single rear-wall-expansion cavity. The numerical solver and the LES methods were validated against available experimental data and the numerical results were shown in good agreement with the experiments. Effect of the cavity rear wall height on the non

Background: Type 2 diabetes (T2D) and poor mental health are two major public health concerns in Europe. Ethnicity is identified as a risk marker for both conditions. Middle-Eastern immigrants represent the largest group of non-European immigrants in Sweden and are at increased risk for T2D. In clinical trials, lifestyle interventions focusing on physical activity and healthy diet have been shown

This article documents the muon reconstruction and identification efficiency obtained by the ATLAS experiment for 139 fb - 1 of pp collision data at s=13 TeV collected between 2015 and 2018 during Run 2 of the LHC. The increased instantaneous luminosity delivered by the LHC over this period required a reoptimisation of the criteria for the identification of prompt muons. Improved and newly develop

For polarization-resolved reflection experiments such as ellipsometry, not only is high reflectivity in a wide spectral range required for mirrors but also the quality of their polarization response is important. Furthermore, for VUV ellipsometry, optimal angles of incidence at the sample are between 45° and 60° with respect to the surface normal. In the best case, a setup should even allow variab
