This paper presents a new interpretation of the binary blending operator of implicit modeling. Instead of considering the operator as a composition of potential functions, we propose to consider it as an implicit curve extruded in an implicit extrusion field. An implicit extrusion field is a 2D space for which each coordinate is a potential field. The study of general concepts around implicit e...

Egg stalk silks of the common green lacewing Chrysoperla carnea likely comprise at least three different silk proteins. Based on the natural spinning process, it was hypothesized that these proteins self-assemble without shear stress, as adult lacewings do not use a spinneret. To examine this, the first sequence identification and determination of the gene expression profile of several silk pro...

Pretreatment of biomass before subjecting it to enzyme saccharification is crucial with regards to facilitating access of enzyme to biomass. Extrusion, as a continuous and cost-effective pretreatment method, combines heating with high shear and mixing resulting in much greater specific surface areas of biomass. The objective of this study was to examine the effect of extrusion as a pretreatment...

The ultrastructural cytology and reproduction of Amphiacantha longa Caullery et Mesnil, 1914 is described. Merogonial reproduction was not observed. The sporogony follows two lines: free disporoblastic and enveloped, polysporoblastic, involving sporoblast mother cells. The enveloped sporogony is endogenous in spore sacs of sporont origin, daughter cells are formed by vacuolation. Probably all s...
