Omdat de consequenties van onveilig handelen groot kunnen zijn in de Rotterdamse haven, heeft veiligheid de grootste prioriteit bij zowel werkgevers als werknemers. Nog steeds worden veiligheidsinstructies op veel plekken via een klassieke lesmethode – door informeren, toepassen en toetsen – overgebracht aan de werknemers in de haven. De inzet...

Omdat de consequenties van onveilig handelen enorm kunnen zijn in de bouw- en industriesector, heeft veiligheid er de hoogste prioriteit. Daarom vinden TNO-onderzoeker Karen Oude Hengel en business developer Geeske Steeneken het een gemiste kans dat veiligheidsinstructies in de industrie op veel plekken nog steeds op een klassieke manier worden...

Wrinkling of elastomeric coatings by an electric field is reported. The associated changes in the coating's optical properties yield switchable mirrors and windows. The field Ec needed to induce wrinkling is a factor of 4.4 lower than the theoretically predicted value, which is attributed to space-charge injection. Copyright © 2013 WILEY-VCH...

The thickening functionality of four acetylated di-starch adipates with variations in starch source and amylose and adipate contents was evaluated in a simplified small-scale model sauce system at fourteen processing conditions with variations in temperature, shear, and pH. A processing stability factor for a given starch was defined as a...

A laboratory-scale process is presented for the manufacture of starch and gluten from wheat. Main feature of this process is that whole wheat kernels are crushed dry between smooth rolls prior to wet disintegration in excess water in such way that gluten formation is prevented and fibres can be removed by sieving. Centrifugation of the endosperm...

The aim of this work was to identify the transitions in the complex DSC profiles of potato starch at a low water content. Preparative DSC involves the thermal processing of samples in stainless steel DSC pans in a way that allows their subsequent structural characterization. The low temperature (LT), dual melting (M1-M2), and high temperature ...

When aqueous potato starch suspensions were heated into the solution state and cooled, spreadable particle gels were obtained with a spherulite morphology and a cream-like texture. This so-called superheated starch (SHS) exhibits more effective gelling properties than maltodextrin, which is currently applied as a fat mimetic. In addition, a gel...

The occurrence of surface effects in the acetylation of granular potato starch with acetic anhydride to degrees of substitution 0.04-0.2 was studied by two different approaches. The first approach involved the fractionation of granular starch acetates into five different size classes and analysis of their acetate content. Alternatively, two...

TNO Kwaliteit van Leven heeft een nieuwe vetvervanger op zetmeelbasis ontwikkeld, die als 'clean label'-ingrediënt toegepast kan worden. Het is in lage concentraties al functioneel. Hierdoor is er minder van nodig, wat leidt tot een lagere energie-inname bij consumptie.

The effect of the granule structure on the methylation of starch was investigated by comparing the substitution patterns of potato starch methylated in granular suspension and in solution to DS 0.3. Substitution patterns were analyzed by successive digestion with α-amylase and amyloglucosidase, fractionation of the resulting malto...

Amylomaltases or D-enzyme (4-α-glucanotransferases; E.C. 2.4.1.25) are carbohydrate-active enzymes that catalyze the transfer of glucan units from one α-glucan to another in a disproportionation reaction. These enzymes are involved in starch metabolism in plants or maltose/glycogen metabolism in many microorganisms. The amylomaltase of the...

Introduction: Elevated hearing thresholds have been documented in some astronauts after long-term spaceflights although noise levels were lower than those normally associated with noise-induced hearing loss in ground-based operations. The present study was conducted to determine whether prolonged exposure (70 h) to levels (72 dBA) recorded on...

While the Speech Transmission Index ~STI! is widely applied for prediction of speech intelligibility in room acoustics and telecommunication engineering, it is unclear how to interpret STI values when non-native talkers or listeners are involved. Based on subjectively measured psychometric functions for sentence intelligibility in noise, for...

Active noise reduction is a successful addition to passive ear-defenders for improvement of the sound attenuation at low frequencies. Design and assessment methods are discussed, focused on subjective and objective attenuation measurements, stability, and high noise level applications. Active noise reduction systems are suitable for integration...

In an earlier study we derived robust frequency-weighting functions for prediction of the intelligibility of short nonsense words.These frequency-weighting functions are applied for prediction of intelligibility such as with the speech transmission index (STI).Six independent experiments revealed essentially similar frequency-weighting functions...
