Bacteria utilize complement regulators as a means of evading the host immune response. Here, we describe protocols for evaluating the role vitronectin acquisition at the bacterial cell surface plays in resistance to the host immune system. Flow cytometry experiments identified human plasma vitronectin as a ligand for the bacterial receptor outer membrane protein H of Haemophilus influenzae type f.
The parabolic equation is approximated by a set of ordinary differential equations and by finite difference equations. special attention is given to the approximation of the boundary condition. Some identities suitable to check numerical calculations are also derived.
Purpose: This paper aims to explore how the ownership transfer from a highly industrialised country to less industrialised countries influences consumers’ brand perceptions. Design/methodology/approach: Three acquisition cases of premium car brands (Jaguar, Land Rover and Volvo) are investigated using qualitative data from online brand communities. Findings: When country of ownership (COOW) for br
This paper presents the case study of a newly constructed 1600 m2 kindergarten building in Oslo, Norway. The building has been designed within the framework of the Norwegian Research Council Project LowEx, which aims at engineering solutions to achieve a seasonal coefficient of performance (SCOP) of 6–10 for heating, a seasonal energy efficiency ratio (SEER) of 80–100 for cooling, and an 80% reduc
Many reinforced concrete bridges in Europe and around the world are damaged by reinforcement corrosion and the annual maintenance costs are enormous. It is therefore important to develop reliable methods to assess the structural capacity of corroded reinforced concrete structures and avoid unnecessary maintenance costs. Although there are advanced models for determining the load carrying capacity
Combining sustainable consumption with the circular economy concept could help tackle challenges, such as resource scarcity and climate change by reducing resource throughput and increasing cycling of products and materials within the economic system, thereby reducing emissions and virgin material use. To achieve sustainable consumption in a circular economy production and consumption practices ne
Precis som för bilindustrin, investeras stora belopp på att skapa obemannade fartyg. De huvudsakliga fördelarna är att säkerheten förväntas förbättras, vinsternakommer att öka, samt att utsläppen kommer att minska. Helt autonoma fraktfartyg förväntas kunna korsa Atlanten helt obemannat innan år 2030, och fram tillsdess förväntas tekniken gradvis förbättra säkerheten och ersätta arbetsuppgiftersom As for the automotive industry, large efforts are being made by industry andacademia to create autonomous ships. Te solutions for this is very technologyintense, as many building blocks, often relying on AI technology, need to worktogether to create a complete system that is safe and reliable to use. Even whenthe ships are fully unmanned, humans are still foreseen to guide the ships whenunknown si
A neutral ceramidase activity stimulated by bile salt was previously identified in the intestinal content. Recently, bile salt stimulated lipase (BSSL) was found to have ceramidase activity. It is unknown whether the ceramidase activity previously found is attributable to BSSL. To address this question, we compared the behaviors of high quaternary aminoethyl (HQ) anion exchange chromatography, the
Social entrepreneurship is a hot topic on many campuses around the world. The past decade has seen the birth of many a course on starting up social ventures, the development of whole educational programmes on social innovation, the establishment of university centres for the promotion of social impact and the launch of incubation labs for students who want to make the world a better place. Althoug
Businesses today need to recognize that they have to be fast at realizing and exploiting new competitive advantages before the opportunity is lost. Instead of the traditional focus on price and quality, there is a shift towards the delivery of value to customers. This is strongly connected to the reduction of downtime of production and high reliability. Here the spare parts supply chain plays an i
The field of child welfare could be considered one of the most complex social systems to work within. Whether punishing for errors or satisficing calls for accountability with firing employees and pointing to individuals as the root causes of bad outcomes, the current practice in child welfare is to utilize backward looking accountability. It is argued here that child welfare agencies would benefi
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
With this thesis we want to prove that by using a single formula for picking stocks, Joel Greenblatt’s ‘’Magic Formula’’, it is possible to achieve returns higher than those achieved by a related index. To prove this, we will construct a portfolio, according to “The Magic Formula”, and backtest the portfolio in the Swedish stock market. The test period will be March 1999 to January 2010 and we wil
We present an up-to-date, comprehensive summary of the rates for all types of compact binary coalescence sources detectable by the initial and advanced versions of the ground-based gravitational-wave detectors LIGO and Virgo. Astrophysical estimates for compact-binary coalescence rates depend on a number of assumptions and unknown model parameters and are still uncertain. Themost confident among t
Simulations of climate over the Last Millennium (850-1850 CE) have been incorporated into the third phase of the Paleoclimate Modelling Intercomparison Project (PMIP3). The drivers of climate over this period are chiefly orbital, solar, volcanic, changes in land use/land cover and some variation in greenhouse gas levels. While some of these effects can be easily defined, the reconstructions of sol
The light-dependent regulation of stromal enzymes by thioredoxin (Trx)-catalysed disulphide/dithiol exchange is known as a classical mechanism for control of chloroplast metabolism. Recent proteome studies show that Trx targets are present not only in the stroma but in all chloroplast compartments, from the envelope to the thylakoid lumen. Trx-mediated redox control appears to be a common feature
The phylogeny of the subfamily Xanthorioideae (Teloschistaceae) is re-analysed based on ITS, LSU and mtSSU sequences, including a new set of specimens representing 31 genera, of which five are proposed as new: Golubkovia, Igneoplaca, Langeottia, Scythioria and Verrucoplaca. Two new species, Ovealmbornia volkmarwirthii from South Africa and Gondwania sejongensis from Antarctica are described, illus
