Simple, high current LaB_6 cathode

A cathode constructed of a thin, directly heated strip of LaB_6 is described. The cathode is simple to construct, requires modest heating power, has high current emission capability and is quite rugged. Construction details will be given and cathode performance data presented. The cathode has been used in tokamak dc current injection experiments

Experimental Determination of the Transversal and Longitudinal Fibre Bundle Permeability

In the resin transfer moulding process, fabrics are very often used as reinforcement. These fabrics consist of fibre bundles. In this context, both the permeability of the macroscopic fabric and the permeability of the fibre bundle are the key parameters to accurately predict the impregnation of the fabrics, the impregnation time and resulting void content. The fibre bundle permeability can be either predicted theoretically or experimentally. Whereas the theoretical determination lacks on accuracy as the realistic packing of the fibres in the bundles is not integrated in the models. In this work, we present an experimental setup to measure the longitudinal and transversal permeability of fibre bundles. The results are compared to model prediction

An Analysis of Perceptions of the Relationship Between the Athletic Director and Athletics’ Direct Reports in NCAA Division II

The roles and responsibilities of the individual designated as the athletics’ direct report (ADR) on NCAA Division II member institution campuses are not clearly defined. The absence of clear guidelines creates the opportunity for differences in the relationships between the athletic director (AD) and the designated ADR between peer institutions. The purpose of this study was to explore the current relationship between ADs and ADRs and analyze current practices. Results indicated positive relations between ADs and ADRs on campus and that communication is key to a successful relationship. Recommendations for practitioners are discussed
