The aim of this study was to determine how roots and their ectomycorrhizal symbionts affect the fluxes of nitrous oxide (N2O) from nutrient-rich drained organic forest soils. Specifically, the relative impacts of roots and mycorrhizal mycelia on N2O fluxes were investigated using two different trenching treatments, excluding (a) roots or (b) roots and mycorrhizal mycelia, from the soil. N2O fluxes

High-spin states have been studied in Pr-135(59), populated through the Cd-116(Na-23,4n) reaction at 115 MeV, using the Gammasphere gamma-ray spectrometer. The negative-parity yrast band has been significantly extended to spin similar to 45 (h) over bar and excitation energy 21.5 MeV, showing evidence for several rotational alignments. The positive-parity yrast band of Ce-135(58), populated throug

Our study had three objectives: to extend the plasmid-based transformation protocol to a clinical isolate of C. trachomatis belonging to the trachoma biovar, to provide "proof of principle'' that it is possible to "knock out'' selected plasmid genes (retaining a replication competent plasmid) and to investigate the plasticity of the plasmid. A recently developed, plasmid-based transformation proto

Ur regnskogens skugga berättar om en ovanlig resa. År 1754 gav sig Daniel Rolander iväg på en strapatsrik färd till Sydamerika och Surinams urskogar. Han var Carl von Linnés mest litterärt begåvade lärjunge och hade skickats ut för att insamla växter och djur och beskriva landet. Resultatet av den tvååriga resan blev rika samlingar och en 700-sidig resejournal som målande berättar om växt- och dju

Glioblastoma multiforme (GBM) is the most common brain tumor in adults. It presents an extremely challenging clinical problem, and treatment very frequently fails due to the infiltrative growth, facilitated by extensive angiogenesis and neovascularization. Pericytes constitute an important part of the GBM microvasculature. The contribution of endogenous brain pericytes to the tumor vasculature in

The factors in self-report inventories measuring the five-factor model (FFM) correlate with one another although they theoretically should not. Study 1 showed, across three different FFM-questionnaires, that almost all of the common variance between factors can be attributed to a single general factor related to social desirability. In Study 2, simple rephrasing of items from a FFM-questionnaire m

Dorsal agenesis of the pancreas is a rare congenital disorder. We report a case of a 65-year-old man with mild abdominal pain and insulin-dependent diabetes mellitus. Computed tomography (CT) of the abdomen showed a short pancreas with no pancreatic tissue ventral to the splenic vein. Magnetic resonance cholangiopancreatography (MRCP) visualized the absence of a dorsal duct system and confirmed th

This paper investigates the decision-making processes of mayors on the municipal level in Brandenburg, Germany, to support 100% renewable energy policies as well as the respective key success factors. Three different cases and their specific settings are examined: (1) Turnow-Preilack with Germany's largest solar power plant, (2) Prenzlau, a town claiming the title 'City of Renewable Energy’ and (3

The association between low levels of vitamin D and the occurrence of chronic widespread pain (CWP) remains unclear. The aim of our analysis was to determine the relationship between low vitamin D levels and the risk of developing CWP in a population sample of middle age and elderly men.

A new energy and angle resolved analyzer for photoelectron spectroscopy is described. This analyzer is based on combining an advanced focusing electron lens system with time-of-flight measurements. A position sensitive detector gives time and position for the electron events. From this information the kinetic energy and start direction are obtained through a transformation procedure, giving both a

Review of William Skidelsky,Federer and Me. A Story of Obsession.

The premise of this article is that climate effects on lakes can be quantified most effectively by the integration of process-oriented limnological studies with paleolimnological research, particularly when both disciplines operate within a common conceptual framework. To this end, the energy (E)-mass (m) flux framework (Em flux) is developed and applied to selected retrospective studies to demons

It has been argued that high-multiplicity proton-proton collisions at the LHC may exhibit collective phenomena usually studied in the context of heavy-ion collisions, such as elliptic flow. We study this issue using DIPSY-a Monte Carlo event generator based on the QCD dipole model. We calculate the eccentricity of the transverse area defined by the spatial distribution of produced gluons. The resu

Cities are crucial to mitigating climate change and can serve as sites for innovations, providing examples of ways to conduct effective politics in transport, energy and land-use. What does it take to become a model for climate politics? This article argues that a few innovative measures will not suffice. A common vision based on broad legitimacy is crucial to achieving this position. Using a theo

This paper describes a novel approach to the quantitative investigation of the impact of varying relative humidity (RH) and temperature on the structure and thermodynamic properties of salts and crystalline cement hydrates in different hydration states (i.e. varying molar water contents). The multi-method approach developed here is capable of deriving physico-chemical boundary conditions and the t

This thesis provides knowledge of occupational engagement in day centres for people with psychiatric disabilities and contributes to measurement development in the area of occupational engagement. The first study focused on the characteristics of the occupations carried out at the day centre by exploring occupational engagement using time-use diaries with a person-environment-occupation perspectiv
