Using a ground-based and an above-canopy eddy covariance system in addition to stem respiration measurements, the annual respiratory fluxes attributable to soil, stems and foliage were determined for a Scots pine (Pinus sylvestris L.) forest growing in central Siberia. Night-time foliar respiration was estimated on the basis of the difference between fluxes measured below and above the canopy and
This paper presents a state-of-the-art analysis of current systems for product identification utilized within the Swedish sector of construction and facility management. The study also discusses the concept of object and class identification in information systems development. The purpose of the study is to identify and define concepts in a common information structure that provides a framework fo
Avdelningen för Fastighetsvetenskap, LTH, Lund universitet utbildar lantmätare i juridik och ekonomi. Vi bjuder nu in till ett heldagsseminarium om en fråga där lantmätare ofta möter jurister, nämligen förvärv av fastigheter genom fastighetsreglering istället genom köp som fullbordas med lagfart. Seminariet kommer att behandla bland annat följande: • Bakgrunden till möjligheten att förvärva geno
This book chapter discusses gender variations in modern art in Sweden and internationally.
Popular Abstract in Swedish Immunförsvaret är till för att bekämpa patogener såsom bakterier, virus, parasiter och svamp. Det kan också bekämpa cancerceller även om dessa har en förmåga att undkomma till slut. För att kunna känna igen och eliminera främmande kroppar måste immunförsvaret kunna skilja på dem och våra kroppsegna ämnen. Immunförsvaret består av vita blodkroppar. Vita blodkroppar är enT cells constitute a heterogenous population of lymphocytes. Their unifying property is that they express surface bound antigen-receptors, called T cell receptors (TCRs). The TCR is a heterodimer composed of either TCRalpha and beta chain proteins (alphabeta TCR) or gamma and delta chain proteins (gammadelta TCR). Depending on which TCR isotype that is expressed, the T cells are divided into alpha
This paper presents a fast, pipelined and scalable hardware architecture for inverting complex valued matrices. The matrix inversion algorithm involves, a QR-factorization based on the squared Givens rotations algorithm, the application of a recurrence algorithm for inversion of an upper triangular matrix R, and a matrix multiplication of R-1 with Q. We show that traditional triangular
The number of electrically driven loads in a modern vehicle is constantly increasing. Many loads that former were mechanically driven will in the future be driven by electricity. This implies that a number of electronic systems have to be packed together in the limited space in a vehicle. When different electronic systems are placed close to each other, there is always a risk for electromagnetic i
The aim of this thesis was to elucidate the mechanisms by which planktivorous fish can affect planktonic communities in lakes and how they may affect benthic communities through their effects on planktonic communities. In a laboratory experiment, nutrients released by fish increased algal biomass and altered phytoplankton community structure, suggesting that fish can affect phytoplankton by direct
