'De menschen koopen alleen boeken, welke ze nodig hebben'. Uitgeverij De Erven F. Bohn, 1900-1940
No full textA history of the Dutch publishing firm De Erven F. Bohn during the years 1900-1940, the study argues that the Dutch publishing industry in this period is characterised by a proliferation of different publishing fields, resulting in a gradual evolution of most large publishing houses from general to specialised. It studies the structure of various publishing fields, particularly by focusing on the different strategies of list building as distinguishing characteristics of the distinctive fields and the subsequent amplification of the segmentation of the Dutch publishing landscape.Modern and Contemporary Studie
Decreased baseline variability on fetal heart rate pattern in a fetus with heterotaxy syndrome
No full textIn a fetus with suspected heterotaxy syndrome, a decreased/absent baseline variability of fetal heart rate pattern developed at gestational week 36(+5) and continued for 5 days until birth at gestational week 37(+2), while repeat biophysical profile scorings with ultrasound were consistently unremarkable. This neonate weighing 2404 g with Apgar scores of 7 (1-min) and 8 (5-min) and umbilical arterial cord blood pH of 7.28 with base deficit of 3.9mmol/L, showed a heart rate of 120 b.p.m. for 3 h after birth, but subsequently developed sinus bradycardia (84 b.p.m.) unresponsive to crying. Isoproterenol initiated 9 h after birth was effective in the increase of heart rate to 120 b.p.m. in this neonate. Brain magnetic resonance imaging at 16 days of age was unremarkable. The decreased/absent baseline variability of fetal heart rate pattern was speculated to have been caused by sinus node dysfunction, and not by reduced fetal oxygenation in this case

Traffic Safety of Kerbs
No full textIn the goal of creating a safer environment for bicyclists and pedestrians, there is an on-going debate about the usefulness of kerbs as a separation between these two modes. Right angled kerb types separate well but are not forgiving. Sloped and levelled kerb types are more forgiving, but the extent to which they separate is unknown. A video analysis is performed, observing almost 15,000 cyclists for 12 different locations. From the analysis, it can be concluded that any kerb type functions well in terms of separating cyclists from pedestrians. The number of movements from bicycle track to sidewalk was very low (0.21%) and no (near-) accidents were found. Due to these findings, it is recommended to design forgiving (sloped and levelled) kerb types. More research is needed on how ‘forgiving’ sloped kerbs actually are.Civil Engineering and GeosciencesTransport & Plannin
Design Study of a Flexible-Membrane Tsunami Barrier Concept
No full textThe inundation height of the Tohoku tsunami of 2011 exceeded the design levels of many coastal barriers and several structures collapsed. Hundreds of seawalls and breakers are (planned to be) (re)built in the Tohoku district. There is much debate about the conventional tsunami walls and it is therefore suggested to consider alternative tsunami barrier. One of the latest innovations in the field o ftsunami barriers, is the so-called 'Tsunami Catcher'. This is a flexible-membrane barrier which is self-deploying when a tsunami occurs, due to the buoyancy of a floating element. The floater is connected to a membrane and cables which hold the floater on its position. During normal conditions, the membrane is folded in a trench-tpye structure and does not form a visual obstruction of the coastline. In this report, a feasibility assesment of the flexible-membrane barrier for the case study of Kamakura is completed.Civil Engineering and GeosciencesHydraulic EngineeringCivil Engineering, Hydraulic Engineering, Hydraulic Structure
The Design of Inflatable Hydraulic Structures
No full textAdditional thesis with a size of 10 European Credits. A Finite Element Method model is established for an inflatable barrier. The inflatable storm barrier of Ramspol in the Netherlands is taken as reference project. The FEM program that is used is called EASY and is specialized in highly deformable structures. With the model, an optimal design for the abutments of the barrier is found.Hydraulic EngineeringCivil Engineering and Geoscience
