The evolving treatment of services of general economic interest under EU law
No full textThis book contains a collection of economic and legal essays written by academics and practitioners who contributed to the elective Master's course ‘State Aid and Public Procurement in the European Union’ at Maastricht University, and to two conferences on State aid and public procurement organised in Maastricht in 2013 and 2014. The course, the conferences and this book aim to provide stakeholders - students, but also practitioners, civil servants, and consumers - with a better knowledge of the EU rules on public procurement law and State aid. By treating these two legal fields in one volume, the book also intends to draw attention to the largely unexplored links and interfaces between public procurement and State aid rules, which both aim to complete the internal market and to prevent the distortion of competition. Both fields also share common concepts, and furthermore observance of public procurement rules may limit the risk of individual transactions being qualified as State aid (as the Altmark case law and related Commission packages illustrate)
An experimental investigation of the photoproduction of pi+ mesons from hydrogen near threshold
No full textThis thesis describes the experimental work carried out by the author from 1953 to 1931 on the investigation of the photoproduction of pi+ mesons from hydrogen near threshold. The research was motivated by the lack of experimental measurements in the low energy region verifying the predicted threshold energy dependence given by Dispersion Relations and the violation in the well known connection between the low energy pion interactions. Chapter I provides a summary of the theoretical attempts to describe the photoproduction of pions from hydrogen and gives a detailed study of the field of low energy plon photoproduction. Chapter II is a review of previous experimental methods and results in the field of low energy plon photoproduction, and illustrates the necessity of an accurate set of experimental results in the low energy region. Chapter III describes the construction of a specially designed, pressure compensated thin-walled liquid hydrogen target, for the detection of low energy pions. The construction and operation of the target and the compensator design was carried out by the author. The initial design or the target was carried out in collaboration with Dr. W. Hogg. Chapter IV describes two methods of detecting mesons, one by a time of flight method and the other by a delayed coincidence technique. The construction and testing of the time of flight telescope were carried out by the author and the experiment was performed In collaboration with Drs. G.H. Lewis and H.E. Asuma. Preliminary tests on the delayed coincidence technique previously developed by Drs. G.Z. Lewis and R.E. Azuma were carried out by the author using a thin polythene target. Chapter V contains a description of the threshold meson experiment which provides the most accurate Information showing the non-linear threshold energy dependence of the cross-section. The author was responsible for the operation of the liquid hydrogen target during the complete experiment which was of three weeks duration, while the operation, monitoring and collection of the experimental data was shared with Drs. G.H. Lewis. R.S. Asuraa and Dr D. Leith. The analysis of the results have been evaluated independently by the author. The thesis concludes with a discussion of the present state of the knowledge in the field of low energy pion physios
Transport and expression in human melanomas of a transferrin-like glycosylphosphatidylinositol-anchored protein.
No full textMelanotransferrin, also called p97, is a cell surface glycoprotein which was first described as a marker antigen for human melanoma cells. Although p97 has a striking structural similarity to human serum transferrin and lactoferrin, its function has not yet been determined. One feature that distinguishes p97 from the other members of the transferrin family is the presence of a stretch of 24 hydrophobic amino acids at the C terminus, previously assumed to form a proteinacious transmembrane domain. In this study, sensitivity to bacterial phosphatidylinositol-specific phospholipase C, biosynthetic labeling with [3H]ethanolamine, and partitioning in Triton X-114 are used to establish that p97 is expressed at the cell surface as a glycosylphosphatidylinositol-anchored protein. In addition, to gain insight into the intracellular transport of p97, biosynthetic transport studies were performed on a melanoma cell line. These studies resulted in the identification of an additional form of p97 which is found in the medium and which likely does not originate from an alternatively spliced form of the p97 mRNA. These findings, together with our recent observation of the co-localization of p97 and the transferrin receptor in brain capillary endothelium (W. A. Jefferies, M. R. Food, R. Gabathuler, S. Rothenberger, T. Yamada, and P. L. McGeer, manuscript submitted) raise important questions about the function of the two forms of p97 detected and the possible involvement of this protein in a cellular iron uptake mechanism that is independent from the transferrin/transferrin receptor system
DESY-01-104 ISSN 0418-9833 July 2001 On the Rise of the Proton Structure Function F 2
No full textA measurement of the derivative (@ ln F 2 =@ ln x) Q 2 (x; Q ) of the proton structure function F 2 is presented in the low x domain of deeply inelastic positron--proton scattering. For 5 10 x 0:01 and Q (x; Q ) is found to be independent of x and to increase linearly with ln Q . Submitted to Phys. Lett. B C. Adloff , V. Andreev , B. Andrieu , T. Anthonis , V. Arkadov , A.

Are healthy workplaces innovative? How workplace health management can help launching workplace innovation
No full textBased on a review of existing literature and studies, the author explores the synergies between workplace innovation and workplace health management. The object of investigation is the overlap between workplace health management and workplace innovation with a hybrid primary focus on concurrent improvement of organisational performance and quality of working life. The review provides an insight into which internal and external elements play a decisive role in the process towards better performance and quality of working life. The author clarifies how workplace health management and workplace innovation share common ground with respect to the salutogenic quality of an organisational system. Moreover, he suggests a model to conceptually distinguish workplace health management and workplace innovation with regard to the specific focus. Finally, the comparison points to opportunities how the two concepts can reinforce each other
