The end of the Cold War and the subsequent dismantling of the Soviet Union has brought about fundamental changes in the Baltic Sea region in the last decade. In view of these developments, this article addresses two central questions when it comes to Baltic Sea security—how can the current peace in the Baltic Sea region be characterized and what are the prospects and problems involved in achieving
Popular Abstract in Swedish En cell är den minsta beståndsdelen av det som vi definierar som liv. Cellen avgränsas av ett cellmembran som gör att rätt miljö, dvs rätt koncentration av alla nödvändiga molekyler, upprätthålls inuti cellen. Cellmembranet består bl a av olika slags fett, sk lipider. Många små molekyler kan fritt passera igenom membranet medan andra kräver specifika transportkanaler i The aquaporins (AQPs) belong to a family of water permeable membrane channels found in virtually all living organisms. Thirteen isoforms of mammalian AQPs are found, whereas in Arabidopsis thaliana 35 genes encoding AQPs are found. The AQPs are distributed in different organs, cell types and in different subcellular membranes. The aquaporins form homotetramers where each monomer functions as an in

The afternoon effect, i.e., that prices in a sequence of auctions with identical items are decreasing with the order in which the auctions are terminated, is a frequently observed phenomenon in empirical auction studies. Using an unsurpassed amount of data from sequential online train ticket auctions, we investigate two hitherto unexplored dimensions inherent in sequential auctions, namely, the ti
This thesis presents a three-particle correlation analysis with pions originating from Sulphur-Lead and Lead-Lead collisions at 200 and 158 GeV/c per nucleon respectively, taken by the CERN heavy-ion experiment NA44. The genuine three-body correlation is suppressed in both colliding systems which indicates that the particle production source is partly coherent. The two-dimensional three-particle c

Recent choir related research has different points of departure. One point of departure involves theory and methodology developed in cultural and social sciences. Another includes historical musicology. With choir as an overarching umbrella concept, the network Choir in Focus provides the scope for cooperation across national and disciplinary borders. This includes cooperation between the traditio
Popular Abstract in Swedish Det stratosfäriska ozonlagret håller på att förtunnas och detta kommer att leda till att mer skadlig ultraviolett-B (UV-B) strålning når ner till biosfären. För att undersöka hur detta påverkar ett subarktiskt hedekosystem har vi bestrålat ett sådant med extra UV-B strålning motsvarande 15 % ozonförtunning. Studierna har utförts på en dvärgbuskhed vid Abisko NaturvetensThe stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). An ozone depletion of 15 % under clear sky conditions was simu
Unattended Ground Sensor Networks (UGSN) are becoming increasingly popular for surveillance and situational awareness applications. Acoustic sensors can be used in UGSN to detect and to classify targets, and these sensors are cost efficient, easy to deploy, and above all, non-jammable since they are passive. An array of acoustic sensors can detect multiple sound sources and determine the direction
