The Journey That Saved Curious George: The True Wartime Escape of Margret and H.A. Rey
No full textMany years ago, two Jewish artists from Germany met in Brazil, started a business, fell in love, and got married. The Brazilians could not pronounce their German names, so the couple shortened them to H.A. and Margret Rey. While honeymooning in Europe, the Reys decided to stay in Paris so H.A. could pursue a career as a children\u27s book author and illustrator. During this time, H.A. started developing stories about a curious little monkey, influenced by the many monkeys he saw in Brazil. But Hitler\u27s forces delayed H.A.\u27s plans for the little monkey until he and Margret could safely escape Europe
SBW Buitendijkse zones en afslagbeheer: Inventarisatie beschikbare kennis, witte vlekken en rekenmodellen
No full textIn deze rapportage wordt een beeld gegeven van de huidige beschikbare kennis en leemten daarin en de op dit moment beschikbare rekenmodellen. De faalmechanismen van dijken van voorland en dijken worden behandeld met veiligheidseisen, belastingen en sterktes. Het doel daarvan is om inzicht te krijgen in de specifieke onderdelen van het project, waarvoor op grond van de huidige beschikbare kennis en rekenmodellen nu al een aanzet kan worden gemaakt en welke onderdelen, die nog een andere uitwerking behoeven of waarvoor nog onvoldoende gegevens beschikbaar zijn
Out and All About: Fables for Old and Young
No full textThe title-page is missing in this book, and the only reference on the web is to a reprint of a book before 1923. At least this reference gives us an author. “Routledge” appears on the spine. I read only the first fable, “The Spider and the Ants,” which lasted some 20 pages and seemed to me to lose some of its focus along the way. The book is generously illustrated with partial-page black-and-white illustrations of various sizes along the way. As the beginning T of C shows, there are here some 31 fables on 256 pages before 18 pages of advertisements. Pretty cover and spine, including gold and black on red cloth.H.A. Pag
Wind Turbines near Flood Defences: Study on the impact craters of falling nacelles hitting a dike
No full textBuilding wind turbines near flood defences has numerous advantages over other locations on land. The water authorities, which own the land of the flood defence, will only permit the turbines if the flood protection assessment satisfies the safety standard after the wind turbines have been constructed. There are three types of failure of a wind turbine: falling over of the turbine, nacelle falling off the tower and blades falling of the rotor. The first two, with their relation to the flood defence, are analyzed in this report. An assessment is made, in which the additional failure probability of the flood defence is determined. The main white spots in the flood protection assessments are: First, the assessment method of wind turbines near flood defences is a gray area, which leaves room for interpretation. Secondly, the effects of the constant vibrations of wind turbines are unknown, this is currently being researched. Thirdly, the size and depth of the crater which develops after an impact of a nacelle hitting the flood defence. This third white spot is researched in this report. The Material Point Method turns out to be a good method to determine the size and depth of a crater. The nacelle of the Enercon E-126 turbine can cause at maximum a penetration depth of 3.8 meters on a dry sea dike consisting of sand. There are two impact locations on the dike which can be distinguished: an impact on the crest and an impact on the slope. If the impact is on the crest, both the crest is and large parts of both slopes are affected. The soil below the slopes is lifted up, this causes the revetment to lose its coherence. An impact on the slope will mainly affect the slope and the crest is only limited affected. However, the size and depth of the crater depend largely on the soil characteristics and the potential energy of the nacelle. Those are taken conservative in the model. So, the penetration depth of 3.8 meters is the maximum. The Expertise Network for Flood Protection gave requirements for wind turbines near flood defences. The case study is again an Enercon E-126 turbine built directly at the inner side of a sea dike in Groningen. Overtopping & overflow, inner slope-instability and instability of the revetment are considered as the governing failure mechanisms for the additional failure probability. When using only conservative assumptions, the flood protection requirements are not satisfied. However, with using more realistic assumptions, the additional failure probability can be determined more precise and therefore be lowered. In the end, the wind turbine can be moved further inland to lower the hitting probability of the flood defence, this will decrease the additional failure probability
Pilotstudie innovatieve dijken Lauwersoog: Ervaringen meerwaardebepaling innovatieve waterkeringen voor de pilotlocatie Lauwersoog
No full textBij Lauwersoog komen een aantal functies bij elkaar: haven, visserij, toerisme, natuur, maar ook waterveiligheid. De waterkering vormt een belangrijk element in het gebied. In dit rapport worden de ervaringen met het bepalen van de meerwaarde van innovatieve waterkeringen voor de pilotlocatie Lauwersoog beschreven. Het Deltaprogramma Waddengebied wil de ervaringen in de pilotstudie gebruiken in brede gebiedsbijeenkomsten, waarin samen met lokale stakeholders wordt gezocht naar geschikte waterveiligheidsstrategieën in het Waddengebied die zich naast waterveiligheid ook richten op doelstellingen voor natuur en voor de ruimtelijke kwaliteit. Uit de pilotstudie Lauwersoog kwam naar voren dat het belangrijk is dat afwegingscriteria locatiespecifiek zijn en afgestemd zijn op de kenmerken en randvoorwaarden en de opgaven, plannen en wensen voor het gebied. Op basis van de ervaringen is de werkwijze voor het bepalen van meerwaarde geschematiseerd. Het is belangrijk dat zowel stakeholders als experts worden betrokken in het proces
