The international research network Choir in Focus held its second meeting during Lund International Choral Festival in October 2010. The seminars included presentations relating to choir and identity, gender, choral leadership as well as intra-musical and artistic questions. One aspect of the network’s activity is to explore possibilities for connections between historical and contemporary perspec

Popular Abstract in Swedish I slutet på 1400-talet såg Christoffer Columbus, som förste europé, gummi användas av indianerna i Sydamerika. Han tog med sig materialet hem till Portugal, men kunde säkert inte föreställa sig de stora mängder gummi som några hundra år senare skulle komma att användas världen över. Mer än 17 miljarder kilo gummi produceras varje år. Nästan hälften är naturgummi och komBiotechnological processes offer environmentally friendly and sometimes cost-effective alternatives to traditional chemical and mechanical methods. It is important to take advantages of the opportunities these processes provide to fulfil the demands and expectations of a future environmentally sustainable society. This work exploits the possibilities of applying biotechnological methods to allow r

Chloroplast gene expression is regulated by developmental and environmental signals. It has been proposed that there is a direct coupling between electron transport in biological membranes and gene expression (J. F. Allen, 1992, Biochim. Biophys. Acta 1098, 275-335). The hypothesis predicts the existence of a sensor in the thylakoid membrane capable of transmitting redox signals to the chloroplast

Laser spectroscopic techniques are powerful tools for monitoring real-world phenomena. A wide variety of methods for establishing spectroscopic contact with a species exist: Absorption, emission, fluorescence, Raman scattering, acousto-optic, and opto-galvanic phenomena. Extreme sensitivity and specificity characterize the methods, which can be used for in situ monitoring and, in some cases, for r

Developing large complex software products aimed for a broad market involves a great flow of wishes and requirements. The former are elicited from customers while the latter are brought forth by the developing organization. These are preferably kept separated to preserve the different perspectives. The interrelationships should however be identified and maintained to enable well-founded decisions.

Recent developments in characteristic mode (CM) analysis enable a more systematic approach to designing multi-antennas for mobile terminals. However, some of the advantages of developing antennas through CMs are based on accurate mode tracking over frequency. Existing tracking methods are primarily based on the tracking of eigencurrents over frequency, by which mode swapping and degenerate modes c

Popular Abstract in Swedish Läkning av achilles-senrupturer är idag en långdragen process, som ofta tar flera månader innan senan är fullt funktionsduglig. Syftet med studierna är att förbättra senläkningen i samband med achillesrupturer. Bone Morphogentic Proteins (BMP) är främst kända för att stimulera benläkning och bentillväxt. De lokala förhållandena har dock visat sig ha stor betydelse för cWe wanted to improve tendon healing by adding a growth factor. Bone Morphogenetic Proteins (BMPs) are well known to stimulate bone healing and bone formation. The local environment is of major importance for cell differentiation after a BMP has been added. Cartilage Derived Morphogenetic Proteins (CDMPs) -1, -2 and -3 (BMP 14, 13 and 12 or GDF 5, 6 and 7) form a subgroup in the BMP-family and are

Popular Abstract in Swedish Interaktiva miljöer erbjuder en märkbar utvecklingmöjlighet när det gäller bl.a. anpassningsmöjlighet samt uppmuntran till handling och interaktion. Fysisk träning och terapi för barn med funktionshinder är ofta varaktig, tröttsam och långtråkig genom att vara repetitiv - och detta är ofta fallet för både barnet och terapeuten. Idag finns emellertid mycket begränsade kdaptive responsive environments that encourage interaction for children with severe disabilities offer a distinct potential for play and learning in rehabilitation. Physical training and therapy for these children is often enduring, tedious, and boring through repetition - and this is often the case for both the child and the facilitator/therapist. Despite this, little is yet known about how the u

Mismatch negativity (MMN) is an EEG voltage fluctuation caused by the brain's automatic reaction to unexpected changes in a repetitive stimulation. In an experiment we studied 68 infants of which 2/3 were born preterm. Due to noise of large amplitude, the MMN is difficult to detect in a single infant's EEG. Therefore grand average, which is a average of many subjects EEG recordings, is sometimes u
