The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to

In cold climates all user requirements for footwear (insulation, waterproof, vapour permeability, drying etc.) can’t be met easily due to their conflicting nature. Defining user conditions is important. Cold may be roughly divided into the three ranges (>+5; +5 to 10; < 10 °C). The choice of proper footwear may be based on this approach. It also reduces some of the conflicting user requirements. U

Methods to achieve admittance matching of rectangular dielectric resonator antennas intended for 60~GHz impulse radio are reported. The motivation is to find a suitable antenna that may be integrated in the V-band gated tunnel diode wavelet generator, replacing its tank circuit and forming a low complexity transmitter. Probed one- and two-port scattering parameter measurements have been performed

The paper presents main conceptual distinctions underlying much of modern philosophical thinking about value. The introductory Section 1 is followed in Section 2 by an outline of the contrast between non-relational value (impersonal good, or good, period) and relational value (good for someone, or—more generally—good for some entity). In Section 3, the focus is on the distinction between final and

Designs for Extremely Large Telescopes (ELTs) are quite well advanced,but the requirements of instruments have had limited impact. Sinceprovision of a suitable environment for instruments is a critical aspectof all telescopes, we outline some well-known and some less-appreciatedchallenges of designing instruments for ELTs. A wide-field spectrometer(WFSPEC) with ~10 arcmin field-of-view, probably w

Popular Abstract in Swedish The phenol oxidase “laccase” was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. However, its use in one of the oldest biotechnologies, i.e. the making of lacquerware in East-Asia, dates back to 5000-6000 BC. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes one elecLaccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product. Based on these highly desired mild oxidising conditio

Carbon nanotubes (CNTs) can be seen as graphene sheets rolled to form cylinders. CNTs may be categorised as single- (SWCNT) or multi-walled (MWCNT). Due to the small size, the number of particles as well as the surface area per mass unit is extremely high. CNTs are highly diverse, differing with respect to e.g., diameter, length, chiral angles, chemical functionalisation, purity, stiffness and bul

Within a course in academic writing, first-term students of English currently construct individualized study-plans detailing both what they should do during the term and when they should do it. Students calculate the average workload for all their courses, and include in their study-plans all the hours they should spend both in and outside the classroom on each course, totalling in 40-hour working
