    Wageningen PhD theses


    This database contains bibliographic descriptions of all Wageningen University PhD theses from 1920 onwards. It is updated on a daily basis by WUR Library.

    Author abstracts and/or summaries are added to all descriptions. A link to the full text dissertation is added to the bibliographic description. In a few cases, no electronic version is available, mostly because of copyright issues.

    Hard copies of all theses are available for loan at WUR Library. To request them, click the link Request this publication in the full record presentation. This is a fee based service.

Lipid production in microalgae [PhD thesis]

Abstract:
Een goed voorbeeld van een bulkproduct dat gewonnen kan worden uit microalgen is triacylglycerol (TAG), een vet dat bestaat uit een glycerol molecuul met daaraan 3 vetzuurketens. Om de productie van TAG te kunnen verhogen is begrip van het biologische mechanisme dat TAG vorming veroorzaakt onontbeerlijk. Het doel van dit onderzoek was dan ook om meer inzicht te krijgen in het mechanisme van TAG accumulatie in microalgen die blootgesteld zijn aan nadelige groeicondities, en om de verkregen kennis te vertalen naar optimale kweekcondities voor TAG productie.

The views of experts and the public regarding societal preferences for innovation in nanotechnology [PhD thesis]

Abstract:
Nanotechnology represents an emerging technology with varied application areas. It has been identified as the next scientific breakthrough with potential for positive impacts for society. The development and application of emerging technologies has been shown to be contingent upon societal responses to those technologies and their applications. Socio-psychological factors will potentially influence societal responses to nanotechnology, and play an important role in its development and commercialisation. The views of both experts and the general public regarding societal preferences for innovations in nanotechnology will be important in identifying which applications will be commercialised. If expert views regarding the determinants of societal acceptability do not align with those held by the general public, applications that consumers will reject may be introduced early in the commercialisation trajectory and focus public opinion on the negative aspects of nanotechnology. Conversely, applications which are acceptable to consumers may never be commercialised if experts perceive that consumers are likely to reject them. This thesis identifies and describes factors influencing societal response to nanotechnology by incorporating views from experts and the general public. Three research approaches were utilised. The first focussed on reviewing previous scientific research into the socio-psychological factors that influence public acceptance of new technologies. The second focussed on identifying and quantifying expert views on the factors that will influence societal acceptance or rejection of nanotechnology. The third tested whether the different factors do, in fact, drive public opinion.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
