In these notes we are going to present a technique which is a multi-dimensional analogue of some methods which are nowadays standard inscattering theory on the real line for the Schrödinger operator. These methods are based on the construction of operators intertwining the Schrödinger operator with the free operator, obtained when the potential term is removed. The multi-dimensional technique us
Disposition ascription has been discussed a good deal over the last few decades, as has the revisionary metaphysical view of ordinary, persisting objects known as 'fourdimensionalism'. However, philosophers have not merged these topics and asked whether four-dimensional objects can be proper subjects of dispositional predicates. This paper seeks to remedy this oversight. It argues that, by and lar
Many of the original sociological premises, concepts and ideas regarding social action, legal change and social reform were initially formulated by studying conditions specific to Western industrial societies. The socio-cultural consequences of globalisation over the last three decades have, however, affected the relationship between state, law and society, blurred sharply drawn distinctions betwe
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
