    Notes: Summary. A total of 369 women with clinical and mycological evidence of vaginal candidiasis received treatment, after random allocation, with either a single oral 150-mg dose of fluconazole (188 women) or 200 mg of intravaginal clotrimazole given daily for 3 consecutive days (181 women). They were assessed at 5–16 days and again at 27–62 days after treatment. Candida species were completely eradicated from the vagina in 72% of the fluconazole group and in 62% of the clotrimazole group at the long-term assessment (P=0·07). Favourable clinical responses were obtained in 99% of the fluconazole group and in 97% of the clotrimazole group at the short-term assessment and in 93% and 84% respectively at the long-term assessment when there was a significant advantage for fluconazole treatment (P=0·02). Symptoms in patients receiving fluconazole were relieved more rapidly (P〈0·001). Treatment-related side-effects were few and minor in both groups. It is concluded that treatment of vaginal candidiasis with fluconazole, as a single oral dose, was more effective in the long term, relieved symptoms more rapidly, and was as safe as treatment with intravaginal clotrimazole.

    Notes: Diamondlike carbon (DLC) thin films have been prepared by chemical vapor deposition assisted by electron cyclotron resonance plasma at low pressure with radio frequency (rf) power applied to the substrate. The microstructure studies by transmission electron microscopy and electron energy loss spectroscopy show the existence of nanocrystalline diamond grains in DLC films prepared at 0.35 Pa. The cluster's size varies from 4 to 30 nm with bias voltage (Vb) varying from −200 to −600 V. A phase transition from hexagonal to cubic diamond was also observed with increasing Vb. © 1997 American Institute of Physics.

    Notes: Abstract Auger electron (AES), electron energy loss (EELS) and X-ray photoelectron spectroscopy (XPS) were used to identify the reaction products at the fibre-matrix interface in SiC nicalon fibre-LAS (Li2O, Al2O3, SiO2) or LAS + Nb2O5 glass matrix composites. Chemical bonding of the different elements was investigated by AES using sputter-depth profiling on fibres extracted from two matrices by etching in hydrofluoric acid. The chemistry of the silicium was studied by EELS in nicalon-LAS + Nb2O5 composite cross-sections. XPS was performed on fibres extracted from the nicalon-LAS + Nb2O5 composite to confirm EELS and AES results. These investigations show that in both composites the reaction scale at the fibre-matrix interface consists of a carbon layer next to the matrix and of a silicate phase rich in oxygen which contains carbon, probably in the form of a silicon oxycarbide, and which is located between the carbon layer and the fibre core.

    Notes: Abstract Secondary ion mass spectrometry (SIMS) and energy dispersive X-ray spectroscopy (EDX) were used to analyse interphases which develop at the fibre—matrix interface during fabrication of SiC nicalon fibre—LAS (Li2O, Al2O3, SiO2) or LAS+Nb2O5 glass matrix composites. SIMS was performed on fibres extracted from composites by dissolution of the matrix in hydrofluoric acid (HF). The composition of the interphases which remain on the fibre periphery was studied using sputter-depth profiling. EDX analysis of the interphases was performed on nicalon-LAS+Nb2O5 composite cross-sections. These investigations show that in both composites the reaction products at the fibre—matrix interface consist of a carbon layer and a silicate phase, rich in oxygen, located between the carbon layer and the fibre core. The analyses also demonstrate the efficiency of SIMS for analysing compositional changes in the near surface of fibres of small diameter.
