摘要:
The invention relates to a method for monitoring changes and states in reaction chambers as well as a supply unit which is used for introducing a liquid culture medium during cell culture analyses. The aim of the invention is to allow for an air bubble-free measurement in reaction chambers so as to monitor changes and states therein without using any degassing process. Said aim is achieved by withdrawing or pumping off a fluid from a receptacle via a hose and/or pipe system and conveying said fluid to a supply unit. The fluid drips or flows into a trickling chamber via an inlet duct, said fluid forming a supply above a head and a reaction chamber. The height of the fluid level, and thus the supply volume, is determined with the aid of a suction duct.

In a method for examination of the surface of an object for a topographic and/or a chemical property, the object-surface is impinged with surface-structure selective biocomponents for examination of a topographic property and/or with chemoselective biocomponents for the examination of a chemical property, together with a nutrient medium and/or an osmotic protective medium for the biocomponents. The biocomponents contained in the nutrient medium and/or the osmotic protective medium are in contact with the object-surface or are spaced from the object surface by less than the detection range of the biocomponents. The object surface is then examined with the biocomponents contained in the nutrient medium and/or the osmotic protective medium by determining at least one examination measurement value. The examination measurement value is compared with a reference measurement value, and conclusions can be drawn about the topographic and/or chemical properties of the object from the result of the comparison. Using the method, an object surface can be examined for a topographic and/or chemical property in a simple manner with a high measuring sensitivity.

A measuring device (1) for measuring or investigating physiological parameters using biological cells or chemical and biologically active substances contained in an analyte (2). The measuring device comprises a sensor (4) with an electronic measurement structure (6) located on a substrate (5). Function-specific receptor cells and/or target cells (7) form part of the sensor (4) and are in direct contact with the measurement structure (6). For measurement, the medium under investigation can be brought into contact with the target cells or receptor cells (7). The measuring device (1) is especially compact in its design and facilitates largely feedback-free investigation of biological or chemical components contained in the analyte.

A process for structuring a surface layer of an object includes applying bio-components to the surface of the object that carry away surface material. The bio-components are contained in at least one of a nutrient and osmotic protective medium. The at least one of a nutrient and osmotic protective medium having the bio-components contained therein is removed after the surface material is carried away from the object surface.

A chip arrangement (1) has a substrate board (2) with an opening (3), into which a carrier chip (4) is inserted, which has an electrical or electronic structural component (5). At least one conductor path (7) is integrated into the carrier chip (4), which connects the structural component (5) to the electrical connection contact (8). The carrier chip (4) is inserted into the opening (3) in such a way that its ends project beyond the opposite-facing, flat-sided surfaces (9, 9′) of the substrate board (2), and thereby form overhangs (10, 10′). Here, the structural component is arranged on the overhang (10) projecting beyond the one surface (9), and the connection contact (8) is arranged on the overhang (10′) projecting beyond the other surface (9′), and the conductor path (7) connecting the structural component (5) and the connection contact (8) passes through the opening (3). A seal is arranged between the substrate board (2) and the carrier chip (4).

Apparatus, systems, and methods may operate to publish one or more stored back end data models accessible to a user interface and a development environment; to receive a configuration context; to generate derived model attributes by filtering, according to the configuration context, back end data attributes associated with the stored back end data models; to derive a set of mapping rules based on the derived model attributes; and store the set of mapping rules to be used to direct run-time data model request transformation activity. Further activities may include receiving an end-user request from a displayed user interface, transforming the end-user request into a transformed request according to the stored set of mapping rules, and transmitting the transformed request to one of the stored back end data models. Additional apparatus, systems, and methods are disclosed.

Some implementations provide a resource planning system for receiving a first scheduling request for a resource's time. This first scheduling request may include a date range and the estimated amount of time needed from the resource, but does not necessarily include concrete date and time facts. This first scheduling request may be refined by a second scheduling request, which specifies concrete date and time facts to schedule a portion of the resource's time that was originally requested by the first scheduling request.

Various embodiments of systems and methods for providing business process visibility at real time are described herein. One or more business activity events are received at a local business activity event manager. Further, business process binding information associated with the one or more business activity events is retrieved at the business activity manager from a business process model manager. A relationship of the one or more business activity events with a business process using the business process binding is identified at the business activity event manager. Upon determination, a business process log manager is triggered for logging a business activity log of a business process instance at real time. Furthermore, the business activity log is extracted to monitor and analyze the business process instance at real time.
摘要:
A device (1) for the carrying out of investigations on cell cultures (2) which take place in a liquid culture medium (4). The device possesses at least a receptacle (3) to contain the culture medium (4) including the cell culture (2), wherein one or more sensors (6) for measurement of the cell culture activities is provided and wherein the receptacle (3) has at least an opening for the adding and the removal of liquid culture medium (4) and the like. A separating element (7) can be introduced into the open upper part of the receptacle (3) and can be brought within the said receptacle (3) in a position close to the bottom (5), in which the said separating element (7) makes a boundary forming a partial space (8) which has a small volume in relation to the entire volume of the receptacle (3). Further, a flow channel (9) is provided, which first, communicates with the small volume partial space (8), and second, communicates with the said reservoir (14). This flow channel (9) and/or the sensors (6) are placed in the area of the small volume partial space (8). By means of the capability for adjustment of the separating element (7) as to its distance from the bottom of the receptacle (3), in the neighborhood of the cell culture (2) a microreaction volume exactly fitting the current requirements can be adjusted. By means of the flow channel (9), the cell culture (2) in the small volume partial space (8) stands in fluid communication with that in the reservoir. For the regeneration of the cell culture solution in the small volume partial space, the separating element (7) can be elevated and depressed, or it is possible, to inject into the small volume partial space of the receptacle (3) a quantity of liquid and by means of a through-flow channel. In this case, a convective mixing of fresh and spent medium takes place through the flow channel (9) between the small volume partial space and the reservoir (14).
