The gram-positive, endospore-forming bacterium Bacillus subtilis contains several membrane-bound c-type cytochromes. We have isolated a mutant pleiotropically deficient in cytochromes c. The responsible mutation resides in a gene which we have named ccdA (cytochrome c defective). This gene is located at 173 degrees on the B. subtilis chromosome. The ccdA gene was found to be specifically required
As semiconductor electronics keep shrinking, functionality depends on individual atomic scale surface and interface features that may change as voltages are applied. In this work we demonstrate a novel device platform that allows scanning tunneling microscopy (STM) imaging with atomic scale resolution across a device simultaneously with full electrical operation. The platform presents a significan
Moraxella catarrhalisis a human respiratory pathogen that causes acute otitis media in children and is associated with exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD). The first step inM. catarrhaliscolonization is adherence to the mucosa, epithelial cells, and extracellular matrix (ECM). The objective of this study was to evaluate the role ofM. catarrhalisint

By counting the number of upcrossings of the mean level by a stationary Gaussian process one can estimate the mean frequency of the process. If the mean level is unknown and estimated from the observed mean level, then this crossing estimator is more or less biased, depending on the length of the observation interval. It is shown that if the interval is at least two mean wavelengths, then the bias
Long-term instability in multiplanet exosystems is a crucial consideration when confirming putative candidates, analysing exoplanet populations, constraining the age of exosystems and identifying the sources of white dwarf pollution. Two planets that are Hill stable are separated by a wide-enough distance to ensure that they will never collide. However, Hill-stable planetary systems may eventually
Popular Abstract in Swedish Det knyts stora förhoppningar till högre utbildning. Nästan var tredje svensk tillbringar några år vid universitet och högskolor. Den erfarenhet de får bär de med sig i hela sitt vuxna liv. Den påverkar deras åsikter om vetenskap, kritiskt tänkande och universitetslärare så länge de lever. Högre utbildning ska förse professioner, myndigheter och näringsliv med kvalificeHigher education (HE) is and has been a growing concern for various stakeholders for a considerable time. Sometimes contradictory attempts to reform HE have increased the pressure on academic teachers and contributed to an experience of demand overload. This research conceptualises HE organisations so that dynamics related to change and stability become understandable. A socio-cultural perspective
It is generally accepted that China will be a great competitor to the Western industrialized countries in the twenty-first century. Is this a reasonable opinion? Is it true that China’s size and growth rate are important in measuring its potential as a competitor? Two questions should be considered. First, is the growth rate of the Chinese economy based on productivity gains? If economic growth is
We analyze the convergence rate of the Dirichlet-Neumann iteration for the fully discretized one dimensional unsteady transmission problem. Specifically, we consider the coupling of two linear heat equations on two identical non overlapping intervals. The Laplacian is discretized using finite differences on one interval and finite elements on the other and the implicit Euler method is used for the

Party polarization research at the academic level has been limited so far compared to media coverage. Nonetheless, there is increasing academic attention on the effects of polarization on policy intensity. This study aims to analyse the impact party polarization has on the government response carried out in the EU countries during Covid-19. The specialized literature study how political polarizati
Oestrogen is not only a sex hormone but also an important regulator of the immune system. Expression of the heavy chain of IgM (mu) is essential for B-cell differentiation. However, a small number of IgA-positive B cells can be found in mice lacking the mu chain (mu MT-/-). The aim of this study was to investigate the effects of oestrogen on this alternative B-cell pathway in mu MT-/- mice. Our re
