Low-power vacuum pumps are commonly used for Southern and Northern transfer from agarose gels and for slot and dot blotting. Unfortunately, commercially available vacuum pumps are expensive and susceptible to contamination with transfer reagents. The following describes the use and construction of a very simple and cheap apparatus, which generates and measures a partial vacuum as effectively as...

objective: in all ceramic fixed partial dentures the connector area is a common fracture location. the survival time of three-unit fixed partial dentures may be improved by altering the connector design in regions of maximum tension. the purpose of this study was to determine the effect of buccolingual increase of the connector width on the stress distribution in posterior fixed partial denture...

Assembly planning attempts to arrange product assembly sequences on the basis of the input of product description, similar assembly plans and assembly constraints. Assembly planning is frequently viewed as a creative thinking process, which requires extensive assembly planning experience. Assembly product modeling with mechanical connection functions has increasingly focused on assembly sequenc...

Most diagram editors and graph construction tools provide some form of automatic connector routing, typically providing orthogonal or poly-line connectors. Usually the editor provides an initial automatic route when the connector is created and then modifies this when the connector end-points are moved. None that we know of ensure that the route is of minimal length while avoiding other objects...

An optical package for mounting VCSEL and PIN diodes for transmitting and receiving optical signals has been developed. The diodes couple to the fibers in a commercial MT connector. The package is quite compact with its physical size significantly smaller than that of the MT connector. This design simplifies the testing and assembly of the optical components because the MT connector with the lo...

A five unit fixed dental prosthesis with a pier abutment poses a unique challenge of a fulcrum and torquing forces at the intermediate abutment. The use of a rigid connector can lead to localization of forces on the pier abutment. Therefore, the use of a non-rigid connector as a stress breaker has been advocated to alleviate the situation. The following case report describes the factors associa...

The important meaning of the optical fiber connector scratches detection was introduced based on wavelet packet and machine vision. To detect the optical fiber connector scratches by using the UltraPAC system, aiming at the scratches feature, the method of analyzing and extracting the scratches eigenvalue by using wavelet packet analysis and pattern recognition by making use of the wavelet neur...
