摘要:
A slide viewer capable of simultaneous display of more than one representation of an area of interest of a slide is provided. The slide viewer includes a database containing at least two data files representing different representations for a same area of interest on one or multiple correlated slides or at least two different digital presentations of the same representation. The representations are views of different illumination and/or of different contrast. Associated with the database are a processor and a display. The processor retrieves data files representing different representations of the same of area of interest and displays them on the display. A user is allowed to simultaneously view representations of the same area of interest, where the representations are of views different from each other by either illumination and/or contrast or by the digital information content presented, and/or by the information acquired from multiple correlated slides.

A scanning device for biological slides is provided, which can be operated in an interactive routine mode as well as in an unsupervised high speed automatic mode. In the first case, typical components, which the pathologist is used to operating manually, such as the microscope, the stage and the focus, and which have to be motorized for the automatic unsupervised system mode, are configured to simulate manual use, operation, and response. A non-interlaced area scan camera supports the interactive selection and acquisition of individual images in the manual mode, as well as the continuous high-speed scan motion for the rare event detection and virtual slide scan applications of the system. Due to the particular requirements to accommodate both operational modes, methods are described for constructing the virtual slide out of image tiles with varying overlap areas in the x- and y-directions.

The invention relates to processes and means for the biotechnologically fermentative production of riboflavin (hereinafter also referred to as vitamin B2) and means for the implementation of this process, in particular a modified microbial host cell with increased riboflavin yield. The invention thus provides new processes and means for the regulation of the expression of enzyme activities involved in the riboflavin production of the host cell.
摘要:
Disclosed is a toroidal core current transformer comprising a primary conductor which penetrates the toroidal core and a secondary winding that is wound around the toroidal core. A measuring shunt (RSh) or a load (Zb) is provided at the secondary end. In order to compensate the phase error (f) between the primary current (IP) and the secondary current (Is), a compensation circuit (K) whose capacity (C) is measured substantially according to equation (I) or (II) is provided at the secondary end. In equation (I) or (II), C represents the capacity of the compensation circuit, ω represents the radian frequency, φ represents the phase error between the primary current and the secondary current, Rsh represents the resistance of an optional measuring shunt, and Zb represents the impedance of an optional load. C = tan ϕ ω · R sh ( I ) C = tan φ ω · Z _ ( II )

Disclosed are methods and systems for analyzing images of specimens processed by a programmable quantitative assay or more specifically a robust programmable quantitative dot assay, PDQA, that enable specimens to be imaged and assessed across a wide variety of conditions and applications. Specific embodiments directed to immunohistochemical applications provide more quantitative methods of imaging and assessing biological samples including tissue samples.
摘要:
The present invention relates to a process for operating a centrifuge which has a drive shaft used for loading, a drum which is connected to the drive shaft and has a drum casing and a drum base, a filter with a working region situated within the filter, an annular space formed between the filter and the drum casing, at least one drum base opening which is formed in the drum base and opens out into the annular space, and at least one swirl nozzle which is arranged in such a manner that it injects a fluid through the at least one drum base opening into the annular space. The process according to the invention includes the steps of loading a product suspension into the working region through the drive shaft, centrifuging the product suspension and drying the product suspension, wherein the drum rotates continuously during drying, and a fluid is injected into the drum through the annular space by means of the at least one swirl nozzle, and the rotational speed of the drum during drying is selected such that a product cake formed in the drum does not collapse.
