Pseudo-Supersymmetry and the Domain-Wall/Cosmology Correspondence
The correspondence between domain-wall and cosmological solutions of gravity
coupled to scalar fields is explained. Any domain wall solution that admits a
Killing spinor is shown to correspond to a cosmology that admits a
pseudo-Killing spinor: whereas the Killing spinor obeys a Dirac-type equation
with hermitian `mass'-matrix, the corresponding pseudo-Killing spinor obeys a
Dirac-type equation with a anti-hermitian `mass'-matrix. We comment on some
implications of (pseudo)supersymmetry.Comment: 11 pages, contribution to the proceedings of IRGAC 2006;v3: minor

Chemotherapie bij bacillaire dysenterie
Uit een studie van de litteratuur over chemotherapie met sulfanilamidederivaten blijkt, dat de gevoeligheid van shigellae voor de preparaten nog weinig is nagegaan. Dit feit was aanleiding, om langs verschillende wijze te trachten meer inzicht in de werkzaamheid der chemotherapeutica van de sulfanilamidereeks ten opzichte van bacillaire dysenterie te verkrijgen. ...

Shifting Patterns in Marks and Registration: France, the United States and United Kingdom, 1870-1970
This paper looks at trademarks and brands, beyond the conventional interests of marketing and law, as a way to explaining the evolution of international business and economies in general. It shows that the perspective defended by many scholars such as Chandler (1990), Wilkins (1991, 1994) and Koehn’ (2001), about the Anglo-Saxon countries, and in particular the United States, leading the transition to modern trade-marks is narrow in its focus. Instead of the United States standing out as historically on the leading edge of innovation in the law and practice of trade marking, it appears from several directions to have been on the trailing edge. France and Britain have a more enduring interest in trademarking. The paper also looks at one particular subset of trade mark registration data – non durable consumer goods. These, and in particular food, are the dominant sectors in the three countries in terms of trademarking, reflecting the character of the sectors where imagery associated with the products is so central in competition. The paper relies on original data from three countries, France, the United Kingdom and the United States, in particular trade mark registrations, and the analysis spans for a period of one hundred years period 1870-1970.trade marks, brands, international business history, intellectual property rights, trademark law
A batch modelling approach to monitor a freeze-drying process using in-line Raman spectroscopy
Characterisation of Flavonoid Aglycones by Negative Ion Chip-Based Nanospray Tandem Mass Spectrometry
Flavonoids are one of the most important classes of natural products having a wide variety of biological activities. There is wide interest in a range of medical and dietary applications, and having a rapid, reliable method for structural elucidation is essential. In this study a range of flavonoid standards are investigated by chip-based negative ion nanospray mass spectrometry. It was found that the different classes of flavonoid studied have a combination of distinct neutral losses from the precursor ion [M-H]− along with characteristic low-mass ions. By looking only for this distinct pattern of product ions, it is possible to determine the class of flavonoid directly. This methodology is tested here by the analysis of a green tea extract, where the expected flavonoids were readily identified, along with quercetin, which is shown to be present at only about 2% of the most intense ion in the spectrum
Early changes in diaphragmatic function evaluated using ultrasound in cardiac surgery patients: a cohort study.
Little is known about the evolution of diaphragmatic function in the early post-cardiac surgery period. The main purpose of this work is to describe its evolution using ultrasound measurements of muscular excursion and thickening fraction (TF). Single-center prospective study of 79 consecutive uncomplicated elective cardiac surgery patients, using motion-mode during quiet unassisted breathing. Excursion and TF were measured sequentially for each patient [pre-operative (D1), 1 day (D2) and 5 days (D3) after surgery]. Pre-operative median for right and left hemidiaphragmatic excursions were 1.8 (IQR 1.6 to 2.1) cm and 1.7 (1.4 to 2.0) cm, respectively. Pre-operative median right and left thickening fractions were 28 (19 to 36) % and 33 (22 to 51) %, respectively. At D2, there was a reduction in both excursion (right: 1.5 (1.1 to 1.8) cm, p < 0.001, left: 1.5 (1.1 to 1.8), p = 0.003) and thickening fractions (right: 20 (15 to 34) %, p = 0.021, left: 24 (17 to 39) %, p = 0.002), followed by a return to pre-operative values at D3. A positive moderate correlation was found between excursion and thickening fraction (Spearman's rho 0.518 for right and 0.548 for left hemidiaphragm, p < 0.001). Interobserver reliability yielded a bias below 0.1 cm with limits of agreement (LOA) of ± 0.3 cm for excursion and - 2% with LOA of ± 21% for thickening fractions. After cardiac surgery, the evolution of diaphragmatic function is characterized by a transient impairment followed by a quick recovery. Although ultrasound diaphragmatic excursion and thickening fraction are correlated, excursion seems to be a more feasible and reproducible method in this population
Implementing european programs: creating platforms for innovation of physiotherapy education

Trends in physiotherapy education: retrospective analysis of ECPE presentations
The last decade both physiotherapy and education faced many demands. Educators are challenged to show evidence and report their best practices. An overview of what has been the focus in the ECPE conference show and the main areas of interest and the development in the European Higher Education Area. It provides the opportunity to benchmark towards the policy statement of education of the World Physiotherapy Confederation. Thus increase the consistency and perhaps assisting in formulating a relevant research agenda for the future. The purpose of this study is to give an overview of the trends in physiotherapy education of the last decennium as it is presented at the conferences of the European the World Physiotherapy Confederation (ECPE). A descriptive and retrospective study was carried out and qualitative and quantitative analysis was made on the basis of content and study design/ methodology, by 3 independent reviewers of all abstracts presented at each of the two previous ECPE conferences of 2004 (Estoril - Portugal) and 2008 (Stockholm -Sweden). Categories for content analyses were developed on base of the distribution and main themes used in the conference. This analysis was constrainted by lack of transparency on the description of methodologies in the abstracts and also by the different organization of the abstract books. We needed to create a category "Not Conclusive" and make our decisions based on the rahter classic distinction of qualitative and quantitative study types and methodology. In the results we can find an increase of total presentations from the first to the second conference. In both conference there is a clear preference for special interest issues and in the research the qualitative studies are more favored. There is a total increase in research and implementation research from the first conference to the second. We intepretate this as a logical consequence as in the first conference most of the presentations were focused on new strategies and policies. In the second conference the aim was more directed to the implementation and scientific grounding of these innovations. Educations Institutes and professionals developed more research on Continuous Professional Development, Teaching and Learning strategies, Curriculum Development and Clinical Education. Presumably these topics are related with the European movement – ‘ Europe a strong society in 2020!’, where education and professionals should meet an European standard. The next step could be a comparison with WCPT and educational networks like COHEHRE and ENPHE. It helps researchers and educators to get a better inside of the research agenda and build upon earlier work. It gives an incentive to the development of high quality methodologies. An overview of reports in conferences gives the opportunity to compare with published results and could challenge publishing criteria.N/
