Product Innovation Knowledge Transfer for Developing Countries: Towards a systematic Transfer Approach
The transfer of knowledge on product innovation to small- and medium-sized enterprises and local knowledge institutions in developing countries is expected to be one of the key drivers for competiveness and economical growth, and a part of the solution to environmental and social challenge. In that respect, this PhD study focuses on how the process of the current knowledge transfer takes place and how it can be improved. A combination of literature review and empirical research has resulted into a conceptual framework to describe the complex and dynamic process of product innovation knowledge transfer to developing countries. In order to improve this process, a systematic approach has been developed and operationalized by a needs assessment tool and a design manual: The UNEP Design for Sustainability for Developing Economies (D4S-DE) Manual (www.d4s-de.org). Both tools have been tested in practice by practitioners and have been evaluated by an academic review board.Design EngineeringIndustrial Design Engineerin
Where do we draw lines: professional relationship boundaries and the child and youth care practitioner
The question of professional relationship boundaries is a poignant one, in light of the many boundary grey-zones that are created by the variety of young people’s needs, practice settings and professional relationship contexts within the field of child and youth care. In order to support practitioners’ development of critical thought and awareness of professional boundaries, this paper applies a professional relationship boundaries conceptual framework to child and youth care work, and the literature is consulted to explore the impacts of boundary violations, influences on individual’s boundaries, cues to indicate blurring boundaries, and key strategies to maintain balanced boundaries

J.C. Painter letter to Benjamin Lundy
Letter from J.E. Painter to (presumably) Benjamin Lundy, answering a request for information about the history and operations of the Underground Railroad. Letter includes details of a story of an ex-slave transported on the Underground Railroad through Ohio and stories of the plight of other fugitive slaves crossing the Ohio River.
Benjamin Lundy (1789-1839) was a prominent Quaker abolitionist best known for his development of abolitionist periodicals. His "Genius of Universal Emancipation" was first published in 1821 from his home in Mt. Pleasant, Ohio, and enjoyed a wide circulation across the antebellum United States. In the 1820s, the young William Lloyd Garrison came to work for The Genius. Benjamin Lundy traveled widely seeking subscriptions to The Genius, giving talks about the anti-slavery movement, and observing and documenting the conditions of enslaved people across the Americas. He was also involved in the establishment of freed slave colonies in Mexico
Turbulent wakes of plates with non-equilibrium similarity scalings
We have conducted hot wire anemometry measurements of six different axisymmetric turbulent wakes which demonstrate the existence in all these wakes of non-equilibrium mean flow profile scalings and of the underlying self-preservation and non-equilibrium dissipation scalings. These mean flow profile scalings are different from those of all documented canonical boundary-free turbulent shear flows to date, all of which have been established for very far downstream regions
Energy dissipation and flux laws for unsteady turbulence
Direct Numerical Simulations of spatially periodic unsteady turbulence show that the high Reynolds number scalings of the instantaneous energy dissipation rate and interscale energy flux at intermediate wavenumbers are qualitatively different from the well-known cornerstone scalings of equilibrium turbulence where and are time-dependent rms velocity and integral length-scales. Instead, they both scale as where and are length and velocity scales characterizing initial/overall unsteady turbulence conditions
De werktuigen voor het bemalen van onze polders en boezems gedurende de afgeloopen 20 jaren
Rede, uitgesproken op 15 September 1919, bij overdracht van de waardigheid van Rector-Magnificus. Prof. ir. J.C. Dijxhoorn was rond de 1e wereldoorlog hoogleraar Werktuigbouwkunde aan de TU. Hij was ook Rector Magnificus van 1916-1919. Bij de overdracht van dit rectoraat heeft hij een lezing gegeven over de ontwikkeling van de Nederlandse gemalen in de periode van 1900 – 1920.

The spatial origin of -5/3 spectra in grid-generated turbulence
A combined wind tunnel and computational study of grid-generated turbulence along the centreline shows that the close to -5/3 power law signature of energy spectra in the frequency domain originates in the production region close to the grid where the velocity derivative statistics become quite suddenly isotropic but also where the turbulent fluctuating velocities are very intermittent and non-Gaussian. As the inlet flow velocity increases, these power laws are increasingly well defined and increasingly close to -5/3 over an increasing range of frequencies. However, this range continuously decreases with streamwise distance from the grid even though the local Reynolds number first increases and then decreases along the same streamwise extent. The intermittency at the point of origin of the close to -5/3 power spectra consists of alternations between intense vortex tube clusters with shallow broad-band spectra and quiescent regions where the velocity fluctuations are smooth with steep energy spectra
Perception of validity of clinical and preclinical methods for assessment of torsades de pointes liability
In 2007 a meeting on drug-induced torsades de pointes (TdP) was held in London, UK, under the auspices of the British Society for Cardiovascular Research (BSCR). One of the objectives was to explore the validity of available biomarkers, risk factors and preclinical investigational methods for the detection of drug-induced TdP liability preclinical methods and clinical 'thorough QT' testing. The first symposium was entitled "How validated are current models and biomarkers for testing drug-induced torsades de pointes liability?" Validation, as far as the symposium was concerned, meant that the endpoints measured in the method predict TdP liability specifically, selectively and quantitatively. Topics (and the publications derived from the presentations) were: human volunteer phase 1 studies [Vik, T., Pollard, C., & Sager, P. (2008-this issue), the anaesthetized rabbit TDP model [Carlsson, L. (2008-this issue), the AV blocked canine preparation [Oros, A., Beekman, J.D.M., & Vos, M. A. (2008- this issue), QT interval and its corrections in the in vivo conscious canine [Fossa, A. A. (2008-this issue), the rabbit heart failure model [Hamlin, R. L., & Kijtawornrat, A. (2008-this issue), the rabbit Langendorff preparation and the Screenit approach [Dumotier, B. M., Deurinck, M., Yang, Y., Traebert, M., & Suter, W. (2008-this issue), the wedge preparation [Yan G.-X. (2008-this issue)] and hERG screens [Hancox, J.C., McPate, M.J., El Harchi, A., & Zhang, Y. h. (2008-this issue). Unbeknownst to the speakers before the start of the sessions, the audience were invited, during the session, to rate each approach on a 0 to 10 scale in terms of the extent to which each approach appeared to be validated. The outcome of this exercise forms the basis of this article. We invite you to evaluate for yourselves the accompanying reviews in this edition of Pharmacology and Therapeutics.
