Thin films of a perovskite proton conductor SrCeO3 were fabricated by ArF excimer laser deposition method using bulk SrCeO3 ceramic targets. For incident laser fluences greater than similar to 1 J/cm(2), ablative deposition was observed. SrCeO3 films with predominant growth along the (200) and (121) were deposited on Si and MgO substrates at 600 degrees C. We have found that the oxygen pressure during deposition is the most critical parameter for obtaining oriented films.

Safer sex campaigns directed at heterosexuals have increasingly targeted women to encourage them to take responsibility for condom use. It appears, however, that many women are unable or unwilling to accept this role. In this article we report on one particular kind of obstacle that some women face in initialing condom use. We draw on data from interviews with 14 women, aged 22 to 43 years, about their experiences with, and views of, condoms. There was considerable variability, as well as commonalities, among the women interviewed in the way they regarded condoms. Using a feminist poststructuralist form of discourse analysis, we explored two women's accounts of being unable to initiate condom use despite their stated intentions not to have intercourse without a condom and having condoms in their possession. We suggest that this particular dynamic results from the passivity women can experience th rough being positioned in a discourse of heterosexual feminine sexuality in general and a discourse of heterosexual romance in particular. We discuss how this passivity can be experienced by women who are otherwise assertive and committed to sexual equality, making it confusing and disconcerting for them and others.

The effects of 10 days dehydration and rapid rehydration on the Na and K metabolism in the Bedouin camel were examined. The research was carried out during 2 periods in the summer, a cool and a hot period. In the hot period the effects of dehydration were more severe. The K metabolism was more affected than that of the Na. The K concentrations in the urine declined while those of Na increased. There was also marked changes in the filtered loads, excreted loads and reabsorption of the 2 cations. Following rehydration significant changes in the cation metabolism were recorded within 15-45 min. Antidiuretic hormone and not aldosterone possibly caused the changes in the 2-cation metabolism.

Results are reported for multichannel spectrophotometric observations of the strong IR source centered on the nebulous star HD 44179 and the associated Red Rectangle (RR) nebula, which were conducted over the wavelength range from 0.35 to 1.1 microns. The stellar spectrum is found to be anomalous, with a large Balmer absorption jump and a substantial IR excess. It is shown that the RR is apparently a reflection nebula, has the same Balmer jump as the star, and is redder than the star. Attempts are made to fit the stellar spectrum to model atmospheres for a B star with an abnormal envelope and for a low-gravity F star. The total luminosity of the RR is estimated, its surface brightness is analyzed, and the ratio of the nebula's surface brightness per sq arcsec to that of the star is evaluated. The chemical composition of the dust grains in the RR is considered.
