Explaining the ∼5-million-year delay in marine biotic recovery following the latest Permian mass extinction, the largest biotic crisis of the Phanerozoic, is a fundamental challenge for both geological and biological sciences. Ocean redox perturbations may have played a critical role in this delayed recovery. However, the lack of quantitative constraints on the details of Early Triassic oceanic an
The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of the Astropy Project is the core package astropy, which serves as the foundation for more specialized projects and packages. In this article, we summarize key features in the core package as of the rec
My thesis deals with the VW-Gesetz and its compatibility with the free movement of capital (Art. 56 EC). The whole topic is highly political because Volkswagen is the biggest car-producer in Niedersachsen (Lower Saxony) and provides many jobs in that area. There have been attempts to takeover the company, which have not been successful because the VW-Gesetz includes several provisions, which make
This book deals with the impact of the free movement rules in the EC Treaty on tax treaties in the internal market. This is a highly relevant issue since a provision in breach of teh free movement rules is inapplicable. The potential far-reaching consequences following the preclusion of tax treaty provisions makes it important for taxpayers and governments of teh Member States of teh EU to predict
We present the results of a quantum mechanical modelling of the free carrier absorption (FCA) in semiconductor heterolayers. Elastic and inelastic scatterers are considered with emphasis on the interface defects (optical phonons) contributions to the induced photon absorption for elastic (inelastic) scatterers. Various approaches to FCA are also presented (perturbation, Green's function technique)
Pulsed low energy positron beams provide a unique and non-destructive tool to depth probe the free volume of polymers at surfaces and interfaces. Since the employment of low energy positron beams in polymer research is an emerging technique, some focus in this thesis has been on extracting methods and equations needed to interpret the experimental data. The polymers chosen for this study were sele
Ultraweak light emission (UWLE) was measured from leaves of various chillingsensitive (Lycopersicon esculentum, Cucumis sativus and Phaseolus vulgaris) and tolerant (Pisum sativum and Vicia faba) plants after exposure to low (47C) temperature in the light. UWLE increased upon chilling treatment combined with illumination with 200 mol m2 s1 PAR in all plants, by about 30 in tolerant and by more tha

Purpose: We investigated the value of serum measurements for glandular kallikrein 2 (hK2), and free (f) and total (t) prostate specific antigen (PSA) in a second round of biannual screening for prostate cancer. Materials and Methods: In 1995 to 1996, 5,853 of 9,811 randomly selected men in Goteborg, Sweden 50 to 66 years old had PSA measurements. Of 660 men 611 with tPSA 3 ng/ml or greater underwe
Enligt HSVs rapport ”Kartläggning av distansverksamheten vid universitet ochhögskolor” från 2011 är genomströmningen i landets distansutbildningar betydligt lägre än motsvarande för campusutbildningar. I detta paper kommer jag att belysa fenomenet genomströmning genom att rikta blicken mot MOOCs, en annan typ av nätbaserade kurser än de som vanligtvis diskuteras i sammanhanget. MOOCs erbjuder en m
