A superplastically formed structural assembly is provided, as is an associated preform and method for forming such an assembly. The assembly includes a skin member and a support member that are joined to define a space between the members and between the joints. The assembly can be produced by joining the members in a flat configuration, and then forming the resulting preform to a predetermined shape of the structural assembly. The support member defines at least one aperture in communication with the space between the members. Thus, the skin member can be formed by delivering a pressurized fluid through the support member to the skin member, e.g., to superplastically form the skin member against a die that defines a contour surface corresponding in shape to the predetermined configuration of the assembly. The support member can extend in a substantially direct configuration between opposing portions of the skin member.

The invention provides novel organometallic complexes useful as olefin metathesis catalysts. The complexes have an N-heterocyclic carbene ligand and a chelating carbene ligand associated with a Group 8 transition metal center. The molecular structure of the complexes can be altered so as to provide a substantial latency period. The complexes are particularly useful in catalyzing ring closing metathesis of acyclic olefins and ring opening metathesis polymerization of cyclic olefins.

A portable blower-vacuum includes a housing having an inlet and an outlet. A motor is disposed within the housing for rotatably driving an impeller to transfer an airflow from the inlet to the outlet. The blower-vacuum also includes an elongated air outlet structure over which an elongated blower tube may be slid for attachment in a blower mode and removed in a vacuum mode. The outlet structure possesses a configuration that improves the ease with which the blower tube may be fitted to the air outlet. The blower-vacuum also includes a cover disposed over the inlet in a blower mode and a skirt adapted to cooperate with the cover and the inlet to substantially reduce or eliminate lateral airflow from entering the inlet from between the cover and the housing.

A device and a method are provided for the analysis of a sample plate on which at least two material samples are situated. In the method, one impedance spectrum is measured for each of the material samples. As a function of the respectively measured impedance spectrum, a configuration of a circuit equivalent is determined which includes at least one electronic component. Then, for an error minimization computation, starting values for the components of the respective circuit equivalents are determined. In the error minimization computation, a theoretical impedance spectrum is calculated for at least one of the material samples, based on the impedance spectrum measured for the material sample, as well as the starting values for the components of the respective circuit equivalent, and fit values are determined for the components of the respective circuit equivalent. Subsequently, a validation variable is determined for the calculated, theoretical impedance spectrum, and an evaluation variable is ascertained by comparison of at least one of the fit values for the components to a reference value.

System and method for efficient maintenance of indexes for XML files are described. In one embodiment, the method comprises storing an XML document in an XML database; providing a first XML index definition document (“XIDD”) for defining a first index for the XML document, wherein the first XIDD is applied to the XML document to create a first set of index keys for the XML document stored in the XML database; responsive to a change to the XML document affecting an update node thereof, performing a limited, localized traversal of the XML document around the update node to determine whether the change affects the first set of index keys; and updating the first set of index keys as necessitated by the change.
