Abstract:
The present invention relates to a process for the enantiomeric enrichment of cis-8-benzyl-7,9-dioxo-2,8-diazabicyclo[4.3.0]nonane with the aid of continuous countercurrent chromatography, which is also described as SMB chromatography (SMB=simulated moving bed). In a further aspect, the invention relates to a process for the preparation of (1S,6R)-8-benzyl-7,9-dioxo-2,8-diazabicyclo[4.3.0]nonane using the aforementioned process, which furthermore includes a racemization step.
Abstract:
A method for versioning learning objects comprises identifying learning content, which includes a plurality of learning objects, for storage in a content repository. Each learning object comprises or contains at least one content file. The method then includes comparing first version information of a first of the content files to versioning information obtained from an object version file identifying a prior version of the particular learning object. In response to at least a portion of the first version information of the first content file matching a corresponding portion of the versioning information stored in the object version file, a pointer to a corresponding content file in the prior version of the learning object is stored in a new object version file.
Abstract:
Disclosed herein are systems and techniques to provide for batch processing of wizards. In general, the techniques may include a computer-implemented method that comprises presenting a wizard to a user to perform a step-by-step process, with each step associated with a step type and the step type being one of confirmation, processing, optional input, or mandatory input. The process is executed as a batch process based on a user request. Then, the batch process is interrupted based on an associated step type of a current step, the interrupting comprising comparing the associated step type to a user parameter.
Abstract:
An example method for dynamic learning courses comprises searching a plurality of learning objects to retrieve a subset of the plurality based on at least one search variable. A first learning object from the subset and a second learning object from the subset are identified. The method then includes dynamically creating a learning course using at least the first and second learning objects.

The method also includes processing the structure into a preview. The method further includes presenting the preview. In another embodiment, the invention is a system. The system includes a processor, a bus coupled to the processor, and a memory coupled to the bus. The processor is to detect a change in a structure, process the structure into a preview, and present the preview.
Abstract:
A method and apparatus for a metawizard framework is described. In one embodiment, the invention is a system. In an embodiment, the invention is a method. The method includes executing a portion of a first wizard data in a metawizard. The method also includes determining a second wizard data in the metawizard remains to be executed. The method additionally includes executing a portion of the second wizard data in the metawizard. In another embodiment, the invention is a method. The method includes linking a first wizard data to a metawizard. The method also includes selecting steps of the first wizard data as a portion of the first wizard data to execute. The method further includes linking a second wizard data to the metawizard. The method also includes selecting steps of the second wizard data as a portion of the second wizard data to execute. The method further includes programming control logic to execute the portion of the first wizard data and programming control logic to execute the portion of the second wizard data.
Abstract:
A learning system, method, and software generate a navigation path through a course based on a learning strategy. The course may be navigated by receiving graphs corresponding to the course, applying the learning strategy to the graphs, and generating a navigation path through the course for the learner based on the applied strategy. The navigation path may be used to suggest content from the course for presentation to a learner.
Abstract:
There are provided new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I) ##STR1## in which A and B are identical or different and independently of one another in each case represent hydrogen, alkyl, alkenyl, alkynyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aryl or A and B together represent the bivalent radical of a saturated or unsaturated, optionally substituted, mono-, bi-, tri- or polycyclic system, X represents alkyl, halogen or alkoxy, Y represents hydrogen, alkyl, halogen, alkoxy or halogenoalkyl, Z represents alkyl, halogen or alkoxy n represents a number 0, 1, 2 or 3, G represents hydrogen (a) or the groups ##STR2## in which E represents a metal ion equivalent or an ammonium ion, L and M represents oxygen and/or sulphur, and R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 have the meaning given in the text of the application. The new 3-hydroxy-4-aryl-5-oxo-pyrazoline derivatives of the formula (I) have a particularly pronounced activity against animal pests, in particular against insects and arachnids, and against weeds.
Abstract:
