The 825-1110 angstroms EUV spectrum of Venus.
On 15 August 1994 we launched the EUVS sounding rocket payload to observe the 825-1110 angstrom region of Venus's far ultraviolet airglow spectrum. The EUVS telescope/spectrograph obtained good data at five times higher spectral resolution than was previously available in the far ultraviolet. We present these data and compare our results to those obtained by the Galileo UVS and Venera 11/12 UV spectrophotometers. We identify several new spectral emission features, including both singly ionized nitrogen and molecular nitrogen in Venus's spectrum. We also see evidence for electron-impact-induced emission from CO. Finally, the EUVS data indicate that the "Ar" emissions detected in Venus's far ultraviolet spectrum by Venera 11/12 spectrophotometers are in fact not due to argon, thus eliminating the discrepancy between in situ and remote sensing measurements.

Certifying foreign-trained technologists: should the CSLT change?
The certification of foreign-trained technologists is a very sensitive issue, and the CSLT must proceed with caution in making changes to the system. The policy cannot afford to be too lenient, lest in this litigation-conscious climate an incident were to occur that could undermine the credibility of the certification process. On the other hand, it must not be protectionist and discriminatory. If the labour market does become undersupplied with medical technologists, employers in non-regulated provinces may choose to replace their ranks with non-CSLT-certified employees. If this were to happen to a significant degree, employers might come to rely less and less on the CSLT's stamp of approval. In either case, the value of the CSLT, and the RT itself, is at risk.

Clinical aspects of granulomatous orchitis.
Granulomatous orchitis can present in a variety of forms varying from acute to chronic. Clinically, testicular neoplasm is usually diagnosed and radical orchiectomy is performed, with the correct diagnosis being made on microscopic examination. In this article 6 cases of granulomatous orchitis are presented, with a variety of clinical presentations varying from acute to the more chronic forms.

Peptidergic transmission in the brain. VI. Behavioral consequences of central activation.
Having described a peptidergic transmitter system in the rat brain, we now begin to evaluate its behavioral function. We stimulated cell bodies in the medial amygdaloid nucleus (AME) with indwelling bilateral electrodes. These cell bodies contain a vasopressin-like peptide and send fibers to the hippocampus where the peptide is released upon stimulation. There the peptide inhibits hippocampal output in the awake rat just as it does in the anesthetized rat and in the rat brain slice. The stimulation reorganizes behavior with the same latency and duration as the hippocampal effect. For about 15-20 minutes after the brief stimulus, rats remain motionless with eyes wide open. This "freezing" state is punctuated by episodes of exploratory behavior. The stimulus appears to have a positive affective quality. Review of the literature in light of the present results indicates a probable role for this peptidergic system in the generation of sexual behavior in male rats.
