Inventarisatie van blootstellingsmomenten en beschikbare meetgegevens tijdens het verwijderen van asbestdaken

Informatiemaatschappij

Ontwikkelingen in onder meer sociale media, internettechnologie en platformen lei-den tot nieuwe diensten en resulteren in andere manieren van samenwerken, en ver-snellen daarmee ook maatschappelijke veranderingen. In het tweede decennium van de eenentwintigste eeuw kunnen we stellen dat we ons volop in de informatiemaat-schappij bevinden....

European Regulatory Framework on Novel Foods and Novel Food Additives

In Europe, commercialization of a "novel food (or ingredient)" or a "food additive," requires food companies to follow a premarket approval scheme set up by the European Commission, a long (3-5 years) and costly (R&D and administrative) process for the food operator to consider beforehand when seeking a competitive edge.Other chapters in this...

Team spirit makes the difference: The interactive effects of team work engagement and organizational constraints during a military operation on psychological outcomes afterwards

This article prospectively explores the effects of collective team work engagement and organizational constraints during military deployment on individual-level psychological outcomes afterwards. Participants were 971 Dutch peacekeepers within 93 teams who were deployed between the end of 2008 and beginning of 2010, for an average of 4 months,...

Verwijdering van fenol uit waterige stromen: Nieuw type van solvent impregnated resins omtwikkeld door TNO

Binnen de procesindustrie kan het reinigen van grote, waterige stromen een belangrijk onderdeel van de proceskosten vormen. Voor het verwijderen en terugwinnen van hydrofobe koolwaterstoffen zoals benzeen, bestaan verschillende processen. Het winnen van wateroplosbare koolwaterstoffen is echter een uitdaging. Een nieuwe studie, uitgevoerd door...

Hogere waarde creëren uit algen

Samen met de algenkweker "Algae Food and Fuel" gaat TNO een mobiele algen bioraffinaderij bouwen om op een groot aantal locaties war algen worden gekweekt in te kunnen zetten.

Simultaneous clostridial fermentation, lipase-catalyzed esterification, and ester extraction to enrich diesel with butyl butyrate

The recovery of 1-butanol from fermentation broth is energy-intensive since typical concentrations in fermentation broth are below 20gL -1. To prevent butanol inhibition and high downstream processing costs, we aimed at producing butyl esters instead of 1-butanol. It is shown that it is possible to perform simultaneously clostridial fermentation...

A model of psychological resilience for the Netherlands Armed Forces

In the current study, a model of psychological resilience was developed for the Netherlands Armed Forces and a number of important relations were tested using a longitudinal design. The model of resilience was based on a systematic literature review of resilience in high-risk professions and interviews with military domain experts. The model...

The influence of resilience resources on long-term adaptation after deployment

Psychological resilience is seen as a factor influencing soldiers’ performance, mental health, and long-term adaptation after deployment. Factors related to unit’s morale as evaluated by the Netherlands Morale Instrument were compared to soldiers mental health evaluation six months after return from deployment to Afghanistan. For this study the...

New ways of working: A proposed framework and literature review

The drive towards new ways of working is of great relevance to our modern world. Many companies and organizations have introduced aspects of this new approach in recent years, while many others are on the verge of doing so. The new way of working consists of a large variety of measures enabling flexibility in time and place Expectations are...

Co-start vergroot succes van innovatieprojecten

TNO werkt in veel van haar onderzoeks- en adviesprojecten vanuit een denkkader genaamd 'Co-star(*)'. De 'star' (of asterisk*) is te vervangen door verschillende werkwoorden, zodat je Co-Creatie, Co-Design, Co-Productie, Co-Constructie, Co-Development, Co-Learning en dergelijke krijgt. Co-S tar staat voor open innovatie, voor samenwerken en voor...

Techno-economic evaluation of solvent impregnated particles in a bioreactor

Most fermentation products have a feedback inhibiting effect on the host organism. In situ product recovery (ISPR) can be a means to overcome this product inhibition in fermentations. Particles such as solvent impregnated resins or capsules can be valuable tools for product recovery based on extraction. To evaluate, which kind of particle will...

Short-cut calculations for integrated product recovery options in fermentative production of bio-bulk chemicals

Microorganisms are generally sensitive to high concentrations of products that they excrete. Such product inhibition and toxicity effects can significantly be reduced by the integration of fermentations with separation technologies to remove the products continuously. Cost-calculations are required to select the preferred integration method....

Preparation and analysis of high capacity polysulfone capsules

Since the concept of solvent impregnated resins was introduced in the early 1980s, the technique has been applied to a limited amount of applications. The main disadvantage of the resins was that the amount of solvent inside was limited to approximately 1.5 ml/g polymer. A new generation of solvent impregnated resins is introduced. These...

Extractant selection strategy for solvent-impregnated resins in fermentations

The application of extractants in whole-cell biocatalysis can have a positive impact on industrial fermentations, in terms of productivity, total amount of product produced, and cell growth. When a product is continuously removed from the microorganism surroundings, product inhibition will be diminished. The strategy is exemplified using phenol...
