We investigate the CCN activity of freshly emitted biomass burning particles and their hygroscopic growth at a relative humidity (RH) of 85%. The particles were produced in the Mainz combustion laboratory by controlled burning of various wood types. The water uptake at sub- and supersaturations is parameterized by the hygroscopicity parameter, κ (c.f. Petters and Kreidenweis, 2007). For the wood b

In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum fuscoviride, a specialist on tansy Tanacetum vulgare, and its specialist primary hymenopterous parasitoid Lysiphlebus hirticornis, both of which are characterized by multivoltine

This paper investigates the impact of the completion of the liberalized European Internal Electricity Market on Integrated Resource Planning (IRP) and Demand-Side Management (DSM). The results presented are part of the outcomes of a study analyzing the possibilities of IRP and DSM in this new industry environment. The study, finished in May 2000, is based on empirical surveys of both the present a

Parkinson´s disease is characterized by a progressive degeneration of the nigral dopaminergic system. Treatment of disease symptoms using L-DOPA frequently induces side effects such as L-DOPA-induced dyskinesia. New therapeutic approaches are aimed at preventing neurodegeneration or restoring the dopaminergic system by fetal dopaminergic transplants. In this thesis work, we evaluated the neuroprot

Denna rapport har kallats ”Man kan inte klara hur mycket som helst”, efter ett uttalande från en av de intervjuade cheferna. Studien ingår som ett led i KVAR-projektet vid Arbetslivsinstitutet Syd i Malmö. Vid intervjuerna framkom vissa faktorer i försäkringskassemedarbetarens arbetsmiljö som enligt chefernas beskrivning kan utgöra ett hot mot medarbetarnas hälsa och arbetstillfredsställelse. Ur c

Gas turbines emissions, NOX in particular, have negative impact on the environment. To limit the emissions gas turbine burners are constantly improved. In this work, a fourth generation SIT (Siemens Industrial Turbomachinery) burner is studied to gain information about the formation of NOX emissions. The gas mixtures for the full burner are limited to natural gas with different nitrogen dilutions.

The interdisciplinary symposium ”Microstructures of Learning: Novel methods and approaches for assessing structural and functional changes underlying knowledge acquisition in the brain” took place on May 23, 2014 in Lund, Sweden. The cross-disciplinary meeting brought together researchers from linguistics, psychology, physics, chemistry, and neuroscience in order to discuss how knowledge, in part

A fully integrated 0.6 V 2.6 mA VCO aimed for the GPS L1 band is realized in a 90 nm CMOS process. The VCO operates at 6.3 GHz and a divide-by-four circuit buffer provide the wanted 1575.42 MHz signal. The VCO has a measured phase noise of-103 dBc/Hz at 100kHz offset and a chip area of 1.15mm ², including bondpads.

The article is a description and evaluation of extensive and intensive field survey as a means of locating sites from the bronze and early iron ages in the cultivated landscape of southern Sweden. It includes a discussion of other field survey efforts and recommendations about survey technique. Surface survey in December proved to be a fairly successful means of locating bronze age remains in clay

Systematic variational calculations using the multi-configuration Hartree-Fock method for Li are reported. For 1 s 2 2 s 2 S of Li, an nl -expansion is attempted in configuration space, similar to a partial wave expansion for helium-like systems. The total energy, ionization energy, specific mass shift, and hyperfine contact term are calculated with respect to increasing size of the configuration

Popular Abstract in Swedish Inom jonstråleanalysen används en partikelstråle, vanligtvis av protoner eller alfapartiklar, med hög energi för undersökning av prov. Då dessa partiklar skjuts in i provet sker kollisioner, reaktioner eller annan form av växelverkan med elektroner och kärnor i provets inre. En del av dessa processer ger upphov till högenergetisk strålning som kan studeras med lämpliga In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. Because of the limited range of ions in matter, there is a
