Treatment of vestibular disorders with weak asymmetric base-in prisms: An hypothesis with a focus on Ménière's disease

BACKGROUND: Regular treatments of Ménière's disease (MD) vary largely, and no single satisfactory treatment exists. A complementary treatment popular among Dutch and Belgian patients involves eyeglasses with weak asymmetric base-in prisms, with a perceived high success rate. An explanatory mechanism is, however, lacking. OBJECTIVE: To speculate...

Treatment of vestibular disorders with weak asymmetric base-in prisms: An hypothesis with a focus on Ménière’s disease

BACKGROUND : Regular treatments of Ménière’s disease (MD) vary largely, and no single satisfactory treatment exists. A complementary treatment popular among Dutch and Belgian patients involves eyeglasses with weak asymmetric base-in prisms, with a perceived high success rate. An explanatory mechanism is, however, lacking. OBJECTIVE : To...

Reconciling privacy and security

This paper considers the relationship between privacy and security and, in particular, the traditional "trade-off" paradigm. The issue is this: how, in a democracy, can one reconcile the trend towards increasing security (for example, as manifested by increasing surveillance) with the fundamental right of privacy? Our political masters justify...

Development of a mid-Holocene estuarine basin, Rhine-Meuse mouth area, offshore The Netherlands

A proper understanding of coastal development during periods of rapid sea-level rise is a prerequisite for the prediction of future coastal response to the expected acceleration in sea-level rise. However, the development of back-barrier basins, especially in river-mouth areas, during such periods is still not well understood. Here we show the...

Implicit structural inversion of gravity data using linear programming, a validation study

In this study, a regional scale gravity data set has been inverted to infer the structure (topography) of the top of the basement underlying sub-horizontal strata. We apply our method to this real data set for further proof of concept, validation and benchmarking against results from an earlier forward modelling done elsewhere.Our aim is to...

MIBS past present and future

The microbolometer spectrometer breadboard MIBS is a prism spectrometer that uses an uncooled microbolometer detector array and has been designed for the ESA EarthCARE mission. In order to demonstrate its feasibility a breadboard has been build, and tests have been performed that show good correlation between predicted and achieved results....

Nulling at TNO TPD: Status update

TNO TPD has an extensive experience in the realisation of highly stable passive and active opto-mechanical systems. Future missions of ESA like DARWIN [1] rely heavily on these systems such as metrology equipment, delay lines, nulling equipment etc.. The nulling equipment will be used in the Nulling mode of DARWIN in which it will detect Earth...

Velocity-pressure correlation in stagnation and separation regions on surface-mounted prisms

Experiments are presented for a 1:50 scale model of the Wind Engineering Research Field Laboratory (WERFL) experimental building located on the Texas Tech University campus in Lubbock, Texas. The model was immersed in three different boundary layers generated in the Clemson University wind tunnel. These flows closely simulated the lowest 50 m of...

Motion sickness amelioration induced by prism spectacles

A side effect of the prescription of prism glasses according to the principle of Utermöhlen to improve mechanical reading skills of certain types of learning disabled children, was the alleviation of car sickness. Besides a decrease in reported symptoms after prescription of these glasses, the effect is quantified by a decrease in estimated...
