Technologie en grondstoffen voor vleesvervangers en hoogwaardige eiwitten
In deze studie is een inventarisatie gemaakt van mogelijke grondstoffen en technologieën voor de productie van duurzame eiwitproducten voor humane voeding; eiwitproducten die ter vervanging van minder duurzame vleesproducten geconsumeerd kunnen worden. De studie is uitgevoerd in opdracht van het Ministerie van LNV, programma duurzame voedselsystemen
Rock Powder Can Improve Vermicompost Chemical Properties and Plant Nutrition: an On-farm Experiment
Together with farmers, we evaluated nutrient availability from vermicomposted gneiss powder, assessed its influence on growth promotion, nutrition and heavy metal accumulation in maize plants and the effect on soil chemical properties in the field. Three soil treatments were applied: fertilization with vermicompost with gneiss powder, fertilization with vermicompost without gneiss powder, and soil without fertilization (control), in a randomized block design with five replicates. The dry weight of shoots and the concentrations of potassium, calcium, magnesium, manganese, nickel, chrome and lead in the dry matter of maize were higher with vermicompost with gneiss powder. In the soil, the potential of hydrogen and phosphorus, potassium and calcium concentrations were higher with vermicompost with gneiss. There were no detectable levels of heavy metal wastes in the soil after the experiment. We conclude that vermicomposted gneiss powder has potential for use in agriculture as a nutrient source and can improve soil chemical properties

Urgent bedreigde typische soorten en vegetatietypen van Natura 2000-habitattypen
Dit rapport is de weerslag van een onderzoek naar de urgent bedreigde en potentieel urgent bedreigde typische soorten en de urgent bedreigde en potentieel urgent bedreigde vegetatietypen van de habitattypen van de Natura 2000-gebieden. In totaal zijn 67 typische soorten als Urgent Bedreigd gecategoriseerd; nog eens 26 soorten zijn gecategoriseerd als Potentieel Urgent Bedreigd. Voor de vegetatietypen geldt dat er 15 (sub)associaties Urgent bedreigd zijn. Op een bijbehorende cdrom wordt voor al deze soorten en vegetaties de huidige verspreiding gegeven, of herstel binnen of buiten Natura 2000 zou moeten plaatsvinden, wat de knelpunten hierbij zijn en waar de beste herstellocaties gelegen zijn
Large negative velocity gradients in Burgers turbulence
We consider 1D Burgers equation driven by large-scale white-in-time random
force. The tails of the velocity gradients probability distribution function
(PDF) are analyzed by saddle-point approximation in the path integral
describing the velocity statistics. The structure of the saddle-point
(instanton), that is velocity field configuration realizing the maximum of
probability, is studied numerically in details. The numerical results allow us
to find analytical solution for the long-time part of the instanton. Its
careful analysis confirms the result of [Phys. Rev. Lett. 78 (8) 1452 (1997)
[chao-dyn/9609005]] based on short-time estimations that the left tail of PDF
has the form ln P(u_x) \propto -|u_x|^(3/2).Comment: 10 pages, RevTeX, 10 figure
