Abstract:
Micro-electromechanical system (MEMS) comprising a substrate or substrate parts, and a compliant first segment or segments within the substrate or substrate parts with a predefined positive stiffness, wherein the first segment or segments is or are statically balanced. This is embodied by applying a second segment or segments within the substrate or substrate parts that provide a balancing force to the first segment or segments so as to counteract at least in a predefined working range of the first segment or segments the said predefined positive stiffness.

A method of performing near- field acoustic holography comprises the following steps. Establishing (102) acoustic data representing a set of near-field acoustic holography measurements at a first set of positions. Extrapolating (204) acoustic data using a model-based extrapolation to obtain extrapolated acoustic data relating to a plurality of positions outside the aperture. Applying (108) a spatial frequency transform to the padded acoustic data to obtain data in a spatial frequency domain. Propagating (110) the Fourier transformed acoustic data. Applying (112) a regularization in a wavenumber domain. Performing (114) an inverse spatial frequency transform.
Abstract:
The present invention relates to labelled conjugates, for example alpha 1 intergrin A-domain or collagen adhesin of S. aureus (CNA 35), for imaging extra cellular matrix components. It also relates to compositions and kits comprising these labelled conjugates and to imaging methods in which the conjugates are used. The conjugates of the invention comprise a peptide sequence which binds to an extra cellular matrix component, i.e. to an extra cellular matrix protein or to proteoglycans, and which is coupled to an imaging agent. In particular conjugates which bind to elastin, collagen or to a glycosaminoglycan are envisaged. The conjugates according to the invention have some important advantages over existing tools for imaging extra cellular matrix components, in particular for applications in tissue-engineering experiments or MRI. The use of protein conjugates of the invention allow visualization of very small extra cellular matrix components, such as newly formed collagen fibrils.
Abstract:
The present invention is concerned with the typing of cyanobacteria. Methods and nucleic acids for use therein are presented with which preparations comprising a cyanobacterium can be tested and the cyanobacterium therein classified. The classification can be used to correlate the cyanobacterium in the preparation to a pheno- and genotypic characteristics known for the typed strain. This information is useful in the variety of different applications, for instance in predicting and/or characterising toxic blooms of cyanobacteria in surface water bodies
Abstract:
Electrophoretic system having a separation system and a detection system, where the separation system has a channel (1) and a first separation electrode (2) located at a first end of the channel (1) and a second separation electrode (3) located at the second end of the channel (1), where the separation system is arranged in such a way that a potential difference can be applied between the first and second separation electrode (2, 3), where the detection system, in use, is positioned close to the channel (1) or inside the channel (1), the system having means to reduce a voltage difference between the separation system and the detection system in order to prevent electrical breakthrough between the separation system and the detection system.
Abstract:
Fibre-reinforced material that substitutes for cartilage-like tissue, consisting of a hydrophilic, relatively elastic fibre structure and a matrix of polymerised hydrogel. The fibre/matrix bonding is increased by saturating the fibre in the monomer solution before polymerisation of the hydrogel. The fibre preferably consists of a material based on polyurethane. More particularly, this material contains 10-70 % (m/m) fibres (based on the dry matter) and 1-5 % (m/m) (based on the dry matter) of a substance that contains ionised groups has been added to said hydrogel.
Abstract:
Microreactor, in particular a test reactor with high throughput rate, with a reaction section (3) in which reactions can take place. The microreactor furthermore comprises an inlet section (2), connected to the reaction section (3), for feeding reactants to the reaction section (3) and an outlet section (4), connected to the reaction section (3), for discharging reaction products. The reaction section (3) comprises at least two reaction compartments (10) in which catalyst material to be tested can be placed. At least the reaction section (3) of the microreactor (1) is essentially made of a material that is able to withstand temperatures above 500 °C, for example above 700 °C, and that has good thermal conductivity of more than 50 W/mK, for example more than 100 W/mK. An example of such a material is molybdenum.
Abstract:
Method for computing at least one marginal probability for an observed phenomenon in a probability model which describes probabilities for relationships between said phenomenon and physical parameters by using a Cluster Variation Method (CVM), said model comprising a set of variables xi said variables xi representing observations of said physical parameters, the set of variables including a plurality of subsets; the marginal probability including a subset of the set of variables, the probability model being defined by a probability distribution ppsi(x), the probability distribution ppsi(x) having a potential psi(xi) for each of the subsets.
Abstract:
The invention relates to the field of coronaviruses and diagnosis, therapeutic use and vaccines derived thereof. The invention provides replicative coronaviruses and replicative virus-like particles (VLPs) from which large parts of their genome are (at least functionally) deleted without abolishing their replicative capacities. Said deletion is preferably resulting in at least a functional deletion in that the corresponding gene is not or only partly expressed whereby the resulting gene product is dysfunctional or at least functionally distinct from a corresponding wild-type gene product. One striking result seen with VLPs provided with deletions as provided herein is that said deleted VLP, albeit capable of replication in vitro and in vivo, are in general well attenuated, in that they do not cause disease in the target host, making them very suitable for therapeutic use, said as a delivery vehicle for genes and other cargo (whereby specific targeting may be provided as well when desired), and for use as a vaccine, being attenuated while carrying important immunogenic determinants that help elicit an immune response.
Abstract:
The invention relates to a skin substitute which is suitable for the promotion of the healing of skin wounds. The skin substitute according to the present invention comprises a degradable, hydrophilic matrix, which matrix is permeable for cells, contituted by a collagen and elastin comprising biocompatible matrix material, wherein the matrix of the skin substitute comprises an inhibitor of a protease. Furthermore, the invention relates to a composition showing a protease inhibiting action for the topical application on skin wounds, which composition comprises a protease inhibitor and a pharmaceutically acceptable carrier.
