Preservation of panorama mesdag, the Haque

This paper deals with the preservation of the Panorama Mesdag, a cylindrical painting, more than 14 meters high and 120 meters in circumference. The vista of the sea, the dunes and Scheveningen village was painted by one of the most famous painters of the Hague School, Hendrik Willem Mesdag. It is the oldest 19th century panorama in the world in its original site and a unique cultural heritage. About three years ago the building, which is a uniquely complex structure, was damaged by a nearby excavation. In the years to follow a series of measures have been taken of which the compensation grouting of the foundation is the most extensive from a geotechnical point of view.\ud This paper outlines the history of the damage, the construction of the building and most importantly the extents of the compensation grouting and the result of the grouting and the extensive monitoring. The effectiveness of the grouting is determined and conclusions have been drawn for the still to be performed excavations and construction activities

Influence of inspiration level on bronchial lumen measurements with computed tomography

SummaryBackgroundBronchial dimensions measured in CT images generally do not take inspiration level into consideration. However, some studies showed that the bronchial membrane is distensible with airway inflation. Therefore, re-examination of the elasticity of bronchi is needed.PurposeTo assess the influence of respiration on bronchial lumen area (defined as distensibility) in different segmental bronchi and to explore the correlations between distensibility and both lung function and emphysema severity.Material and methodsIn 44 subjects with COPD related to alpha-1-antitrypsin deficiency (AATD), bronchial lumen area was measured in CT images, acquired at different inspiration levels. Measurements were done at matched locations in one apical and two basal segmental airways (RB1, RB10 and LB10). Airway distensibility was calculated as lumen area difference divided by lung volume difference.ResultsBronchial lumen area in the lower lobes (RB10 and LB10) correlated positively with FEV1%predicted (p=0.027 for RB10; and p=0.037 for LB10, respectively). Lumen area is influenced by respiration (p=0.006, p=0.045, and, p=0.005 for RB1, RB10 and LB10, respectively). Airway distensibility was different between upper and lower bronchi (p<0.001), but it was not correlated with lung function.ConclusionLumen area of third generation bronchi is dependent on inspiration level and this distensibility is different between bronchi in the upper and lower lobes. Therefore, changes in lumen area over time should be studied whilst accounting for the lung volume changes, in order to estimate the progression of bronchial disease while excluding the effects of hyperinflation

The Virtues of Balm in Late Medieval Literature

This article argues that balm, or balsam, was, by the late medieval period, believed to be a panacea, capable of healing wounds and illnesses, and also preventing putrefaction. Natural history and pharmacological texts on balm from the ancient and late antique periods emphasized specific qualities of balm, especially its heat; these were condensed and repeated in medieval encyclopedias. The rarity and cost of balsam, from antiquity through the medieval period, and the high rate of counterfeiting also demonstrate its high demand and significance in medicine and religious ritual. Travel writing and itineraria from the early and central medieval periods added a new layer to ideas about the capabilities of balsam: that it originated from a Christian miracle and was a particularly Christian plant

Wood Densitometry in 17 th and 18 th Century Dutch, German, Austrian and French Violins, Compared to Classical Cremonese and Modern Violins

Abstract Classical violins produced by makers such as Antonio Stradivari and Guarneri del Gesu have long been considered the epitome of the luthier&apos;s art and the expressive tool of choice for the most celebrated violinists. It has been speculated these makers had access to wood that was unique in some way and that this was responsible for their acclaimed tonal characteristics. In an attempt to discern whether the above conjecture is true, we analyzed 17 modern and classical Dutch, German, Austrian and French violins by wood densitometry using computed tomography and correlated these results with our previous study of modern and Cremonese violins; in all studying 30 instruments of the violin family. In order to make this comparison possible we developed methods to cross calibrate results from different CT manufacturers using calibration wood pieces. We found no significant differences in median densities between modern and classical violins, or between classical violins from different origins. These results suggest that it is unlikely classical Cremonese makers had access to wood with significantly different wood density characteristics than that available to contemporaneous or modern makers

Infants’ intentionally communicative vocalisations elicit responses from caregivers and are the best predictors of the transition to language: a longitudinal investigation of infants’ vocalisations, gestures, and word production

What aspects of infants’ prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalisations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they 1) are early instances of intentional communication and 2) elicit verbal responses from caregivers. In study 1, 11-month-olds (N = 134) were observed to coordinate vocalisations and gestures with gaze to their caregiver’s face at above chance rates, indicating that they are plausibly intentionally communicative. Study 2 tested whether those infant communicative acts that were gaze-coordinated best predicted later expressive vocabulary. We report a novel procedure for predicting vocabulary via multi-model inference over a comprehensive set of infant behaviours produced at 11- and 12-months (n = 58). This makes it possible to establish the relative predictive value of different behaviours that are hierarchically organised by level of granularity. Gaze-coordinated vocalisations were the most valuable predictors of expressive vocabulary size up to 24 months. Study 3 established that caregivers were more likely to respond to gaze-coordinated behaviours. Moreover, the dyadic combination of infant gaze-coordinated vocalisation and caregiver response was by far the best predictor of later vocabulary size. We conclude that practice with prelinguistic intentional communication facilitates the leap to symbol use. Learning is optimised when caregivers respond to intentional vocalisations with appropriate language
