    Notes: Examination of Auger transition structures of As and x-ray photoelectron spectra of Si indicates a strong influence of the As ion implantation stage on the surface characteristics of (100) silicon. Rapid thermal annealing resulted in the electrical activation of a major portion of arsenic in the implanted zone, but a shallow region confined within a depth of ≈200 A(ring) from the surface contained As complexed with Si and O atoms. Surface characterization results agree with the observed degradation in transport properties of solar cells constructed on the As+ implanted and rapidly annealed (100) p-silicon substrates.

    Notes: Zero-field muon-spin-relaxation (μSR) and X-band ESR have been used to study the spin-freezing dynamics in single crystals of the Ising spin glass Fe2−x Ti1+x O5 . Parameters obtained for the power-law and Vogel–Fulcher descriptions of the critical slowing are consistent with other methods for x=0 and indicate significantly slower freezing in Ti-rich samples. Interpretation of cluster effects, observed in x=0.25-μSR data, as a Griffiths-like phase yields an estimate of 61±1 K for the Néel temperature in site-ordered Fe2 TiO5 .

    Notes: Contrary to recent predictions, it has been observed that the addition of small quantities of hydrogen, ethanol, and benzene to nitrogen reduce the output power of a nitrogen laser. N,N-dimethylaniline enhances the output power of the laser by 25%. A Penning ionization process is proposed as a mechanism for quenching the B 3Πg state of nitrogen.

    Notes: Abstract A procedure is described for the extraction of DNA and RNA from solitary and colonial ascidians obtained on the east coast of Australia. Modifications to more established procedures have been made to avoid nuclease digestion, binding to polyphenolic compounds and other less well characterized pigments that interfere with the use of nucleic acids for restriction-enzyme analysis and gene-cloning. Tissue is homogenized in liquid nitrogen to produce a powder which is washed three times in 0.25 M ammonium acetate, pH 5.0, to remove a variety of contaminants. This is followed by lysis and immediate extraction in a number of different phenol/CHCl3/isoamyl alcohol mixtures. Additional steps are similar to those described in previous methods. Extraction of RNA by this procedure precludes the necessity for addition of ribonuclease inhibitors.

    Description / Table of Contents: Riassunto Il metodo di Chisnell-Chester-Whitham è stato usato per studiare la propagazione di onde d’urto divergenti cilindriche e piane attraverso un gas ideale in presenza di un campo magnetico che ha solo componenti costanti assiali e azimutali, contemporaneamente per casi deboli e forti. Assumendo una distribuzione di densità iniziale ϱ0 = ϱ′r −W , dove ϱ′ è la densità al piano/asse di simmetria ew è una costante, si sono ottenute le espressioni analitiche per la velocità d’urto e la forza d’urto. Le espressioni per la pressione, la densità e la velocità delle particelle immediatamente dopo l’urto sono state determinate per entrambi i casi.
    Notes: Summary The Chisnell-Chester-Whitham method has been used to study the propagation of diverging plane and cylindrical shock waves through an ideal gas in the presence of a magnetic field having only constant axial and azimuthal components, simultaneously for both weak and strong cases. By assuming an initial density distribution ϱ0 = ϱ′r −W , where ϱ′ is the density at the plane/axis of symmetry andw is a constant, the analytical expressions for shock velocity and shock strength have been obtained. The expressions for the pressure, the density and the particle velocity immediately behind the shock have been derived for both the cases.

    Notes: Abstract An immunofluorescence technique was employed to detect the thraustochytrid protist Ulkenia visurgensis (Ulken) Gaertner, originally isolated from an algal bed, in natural samples in Goa, India. Collections were made monthly from September 1985 to November 1986. By treating the samples with antiserum prepared against this organism and conjugated with FITC stain, the protist was regularly found to occur in association with a hydroid. Several cells of the organism were observed in the coelenteron and the hydranth of the hydroid. The thraustochytrid could be repeatedly isolated in cultures from the hydroid. The cells of the protist differed from those in culture in that they lacked ectoplasmic net elements.
