Discharge Gap

This paper studies on a newly developed method, WEDM in gas, and discribes the features of finishing dry-WEDMed surface, such as narrower discharge gap length, higher surface straightness accuracy and no electrochemical etching actions. Low-speed WEDM removal rate in gas can be improved by increasing the wire winding speed. High-speed WEDM in gas has a significant advantage as high removal rate beyond the abovementioned good points, which is available for improving conventional high-speed WEDM quality.

Ultrastructural Findings

Characterization of Borrelia burgdorferi strains by means of negative staining EM has become an integral part of many studies related to the biology of the Lyme disease organism. However, relying solely upon negative staining to compare new isolates with prototype B31 or other borreliae is often unsatisfactory. To obtain more satisfactory results, we have relied upon a correlative approach encompassing a variety EM techniques, i.e., scanning for topographical features and cryotomy, negative staining and thin sectioning to provide a more complete structural characterization of B. burgdorferi.For characterization, isolates of B. burgdorferi were cultured in BSK II media from which they were removed by low speed centrifugation. The sedimented borrelia were carefully resuspended in stabilizing buffer so as to preserve their features for scanning and negative staining. Alternatively, others were prepared for conventional thin sectioning and for cryotomy using modified procedures. For thin sectioning, the fixative described by Ito, et al.
