The aim of the work was to determine quality of an implant mounting within a bone and its strength, as well as to find out, which factors, occurring in the implant-bone system, influence the condition of the contact of an implant mounted within a living tissue the most. The quality of an implant mounting within a bone was experimentally determined by testing 18 samples that had been prepared be...
A novel and easy crystal-mounting technique was developed for the sulfur SAD method using Cr Kalpha radiation (2.29 A). Using this technique, the cryo-buffer and cryoloop around the protein crystal can be removed before data collection in order to eliminate their X-ray absorption. The superiority and reproducibility of the data sets with this mounting technique were demonstrated using tetragona...
A design of communication area for infrared electronic-toll-collection systems to provide an extended communication interval in the vehicle traveling direction and regular boundary between contiguous traffic lanes is proposed. By utilizing two typical low-cost commercial infrared LEDs with different half-intensity angles Φ1/2 = 22◦ and 10◦, the radiation pattern of the emitter is designed to pr...
Déjà vu All Over Again? Although a substantial number of women will suffer and die from breast cancer during the upcoming years, we clearly have made stepwise progress in treating patients with this cancer over the last 3 decades. Each of these steps of progress has led to what are glibly designated “paradigm shifts.” Perhaps the most hotly debated of these paradigms is the local vs systemic na...
A standard sample holder and vial for cryocooled macromolecular crystals has been defined for use with robotic sample changers. This SPINE standard sample holder is a modified version, with added features and specifications, of sample holders in common use. In particular, the SPINE standard meets the precision required for automatic sample exchange and includes a cap that is identified by a two...
The application of the FDTD technique in the calculation of the S-parameters of specific diode mounting and waveguide probe structures is discussed in this paper. Comparative results are given and the FDTD technique is evaluated as an optimized CAD tool. Introduction The finite difference time domain method is used in the RF characterization of diode mounting and waveguide probe structures. A v...
The various models of the Olympus gastrocamera use film of either 4 or 5 mm size, with 32 exposures per roll of film. The developed film is returned from the processing laboratory, therefore, as a film strip, 4 or 5 mm in width, and approximately 34 cm in length. The Olympus Camera Company supply a viewer with a magnifying power of x 10 with each instrument, and this is of some value in examini...
