Resedabi Hylaeus signatusNT (Panzer) (Hymenoptera: Colletidae) påträffat i Botaniska trädgården i Lund.

A first find and a few subsequent observations of the oligolectic Large Yellow-Face Bee Hylaeus signatusNT (Panzer) were made during the second half of August in the Botanical Garden of Lund, province of Scania, Southern Sweden. About a dozen of specimens were attracted to a stand of Reseda luteola, one of its primary pollen sources. This bee is one of several newcomers among solitary bees in SwedA first find and a few subsequent observations of the oligolectic Large Yellow-Face Bee Hylaeus signatusNT (Panzer) were made during the second half of August in the Botanical Garden of Lund, province of Scania, Southern Sweden.

Development of the thermotolerant methylotrophic yeast hansenula polymorpha as efficient ethanol producer

Until recently, the methylotrophic yeasts, including Hansenula polymorpha, have not been considered as a potential producer of biofuels, particularly, ethanol from lignocellulosics. However it is already known that the thermotolerant methylotrophic yeast H. polymorpha is capable to ferment xylose, glucose and cellobiose, the main sugars of lignocellulosic hydrolysates, under elevated temperature.

”Filmreformens förste avantgardist” : Experimentfilmaren Peter Kylberg

This dissertation is about the Swedish filmmaker, painter and composer Peter Kylberg (1938). Kylberg’s nine films produced between 1959 and 1996 serves as a historical delimitation. A purpose of the study is to critically review the existing historical writing surrounding Swedish film culture and film politics, during the timespan in focus. The approach of the dissertation is chronological and pre

Generation of Ultrashort Pulses – From Femtoseconds to Attoseconds

Electronic dynamics takes place on the attosecond timescale and can thus only be studied using a tool with attosecond temporal resolution. High harmonic generation (HHG) provides coherent attosecond pulses in the extreme ultraviolet spectral region. The work presented in this thesis focuses on generating and characterizing ultrashort femtosecond pulses and using them for HHG, together with a gatin

The ins and outs of SMIM1 and its relationship to the expression of Vel blood group antigen

Background: Vel blood group expression is dependent on Small Integral Membrane Protein 1 (SMIM1), a recently discovered erythroid protein. SMIM1 consists of 78 amino acids (aa) and shows only limited homology to other human proteins but is evolutionarily conserved, indicating its importance. The protein has a predicted transmembrane domain but the direction of insertion into the red blood cell (RB

Adsorption, desorption, and redox reactions at iron oxide nanoparticle surfaces

Soils play a critical role in the carbon (C) cycle by regulating the atmospheric carbon dioxide (CO2) levels, and correspondingly the Earth’s climate. However, there are still countless questions of how biological and geochemical soil processes affect the C cycle. To be able to predict future implications on the Earth’s climate, we need to understand these processes. Globally, soils store more C tIron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport. Recently, it has been shown that certain ectomycorrhizal (EC
