    Notes: Abstract The use of a multivariate procedure is demonstrated in the analysis of a survey of various firesafety actions and beliefs in a college student population. A canonical correlation analysis identified three significant factors and revealed that performing a safety inspection of one's residence for potential hazards was associated with beliefs in one's personal efficacy in handling fire situations, whereas engaging in more emergency-related actions such as checking to see if one's smoke detector was working properly, knowing the emergency telephone number, having it posted by the telephone, and knowing two exits out of each area of the home was related to beliefs of susceptibility and seriousness concerning fires. A third factor revealed an association between having a sprinkler system (but not a fire extinguisher) present in the place of residence, vacuuming the dust from a smoke detector, and having ever practiced an emergency escape with beliefs reflecting susceptibility to future (but not present) fire hazards, adequacy of firesafety knowledge, and beliefs in the effectiveness of firesafety inspections. It is shown that the results of this analysis can be quite useful in guiding the development of firesafety education materials; also, the need to differentiate the specific motivational approach depending upon the type of firesafety action being promoted with this particular population is revealed.

    Notes: Abstract An activated titanium electrode with an oxide layer, composed of a mixture of Cr2O3, TiO2 and Sb2O3 (optimal mole ratio chromium:titanium:antimony about 2∶1∶1) has been fabricated by thermal decomposition of the chlorides on a titanium substrate at 650°C. The black-green layer adheres well and has a thickness in the order of micrometres. Its structure is explained using a pore model, based on SEM, AES and electrochemical results. Service life time of electrodes in 1 M H2SO4 for oxidation of isopropanol in terms of the turn over factor of Cr2O3 is between 100 and 400. Preparative electro-organic oxidation of isopropanol, tetrahydrofuran and ethylbenzene have been performed with current densities of 0.5 to 5 mA cm−2. The current efficiencies for the main products, acetone, γ-butyrolactone and acetophenone are 100, 53 and 20%, respectively. These results parallel those of the homogeneous oxidation with chromic acid in solution.

    Potentiodynamic electrodeposition of paint (EDP) (1985)
    Springer
    Journal of applied electrochemistry 15 (1985), S. 825-836 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract Potentiodynamic electropainting at a rotating iron disc electrode has been investigated with three different EDP resins, two anodic from the acrylate type and one cathodic from the epoxide type, and a wide variation of conditions. Voltage scan rate (ν s=1 to 200 Vs−1), voltage range (40 to 200V) and electrode rotation speed (n=60 and 1000rpm) were the most important parameters. The (cyclic) voltammetric curves obtained generally exhibit three characteristic features: (1) The current rises steeply at the start of the experiment. Bath resistance transforms the potentiodynamic curve simultaneously into a galvanodynamic curve. After a transition time, τ, a critical pH is attained at the phase boundary and electrocoagulation occurs. This leads to a rapidly decreasing current density. The sharp c.d. maximum thus established has a peak voltage,U p, which increases withν s according to the relation logU P∼ 1/3 log νs in accordance with theory. (2) At high voltages, a limiting current density is observed, increasing with the square root of νs. This could be quantitatively interpreted in terms of dynamic growth of film thickness governed by Ohmic ion transport in the film. The preceding part of theU/j curve declines withj ∼t −1/2, which indicates the prevalence of space charge effects. (3) Ohmic lines are measured in the course of the first reverse scan and in all quasi steady state follow up cycles. They are flatter by a factor of 1000 in regard to the initial Ohmic line and reflect low voltage Ohmic behaviour of the EDP-film. At high voltages positive current deviations occur due to Child's law. The curves can be measured easily and reproducibly. Due to their salient features it is proposed to use them for characterization of EDP-paints.

    Positive polyacetylene electrodes in aqueous electrolytes (1985)
    Springer
    Journal of applied electrochemistry 15 (1985), S. 159-166 
    Details
    ISSN: 1572-8838

    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract Polyacetylene films, contacted with platinum mesh, have been polarized anodically in aqueous H2SO4, HClO4, HBF4 and H2F2 of medium concentrations (30–70 wt%). Two oxidation peaks are observed, the equivalents of which are 1 $${\text{(1) 0}}{\text{.045 F mol}}^{ - {\text{1}}} {\text{ CH (2) 0}}{\text{.23 F mol}}^{ - {\text{1}}} {\text{ CH}}$$ The potential of the Process 1 decreases linearly with increasing acid concentration by 20–40 mV mol−1 dm−3, while the potential of Peak 2 exhibits normal Nernst behaviour (about + 60 mV decade−1. Process 1 is partially reversible, while Process 2 is totally irreversible. From these findings for Process 1 we conclude the reversible insertion of anions into the polyacetylene host lattice, which is primarily oxidized to the polyradical cation, with the co-insertion of acid molecules HA to yield the insertion compound [(CH)+·yA−·vyHA] x y⩽4.5% andv=1.5 for H2SO4 and HClO4. In the course of Process 2, the polymer is irreversibly oxidized according to $$( - ^ \cdot {\text{CH}} \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot ^ \oplus {\text{ CH}} - )_{x/2} + 2{\text{H}}_{\text{2}} {\text{O}} \to ( - \mathop {\text{C}}\limits_{\mathop \parallel \limits_{\text{O}} } \cdot \cdot \cdot \cdot \cdot \cdot \cdot \cdot \mathop {\text{C}}\limits_{\mathop \parallel \limits_{\text{O}} } - )_{x/2} + 6{\text{H}}^{\text{ + }} + 5e^ - $$ As this process occurs to some extent even in the potential region of Process 1, a continuous degradation of the host lattice occurs upon cycling.

    Length distribution of aluminum etch tunnels (1989)

    Notes: Abstract A model was derived for the length distribution of aluminum etch tunnels, based on an assumed constant death rate per unit length. Both active and dead tunnels were accounted. The model gives reasonable fits to measured tunnel length distribution data with two adjustable parameters, the death rate per unit length and the number of active tunnels. The death rate parameter has a value of about 2% of tunnels dying per μm of growth length for the set of experimental data. The numbers of active and dead tunnels appear to be consistent with other tunnel measurements.

    Notes: Abstract Galvanostatic electrodeposition of polypyrrole from more than 20 nonaqueous and aqueous electrolytes containing anions such as BF 4 − , ClO 4 − , HSO 4 − , Tos−, HCO 3 − , H2PO 4 − , HPO 4 2− , H2BO 3 − and NO 3 − at the substrates Pt, Au, Cu, Ti, stainless steel/V2A and Fe was investigated. The passivating substrates Pt, Au, Ti and V2A could be electrocoated under a broad variety of conditions. Cu dissolved anodically. The same was true for Fe with only one important exception, namely aqueous nitrate. Smooth, well-adhering polypyrrole layers were obtained on iron at NO 3 − concentrations of 0.01–1 M and at current densities of 0.5–10 mA cm−2. The degree of insertion for nitrate ions was abouty=0.25, confirmed by elemental analysis. Current efficiencies with regard to thisy were about 90%. The layers were stable in air for a long time.

    A select and insert sorting algorithm (1988)

    Notes: Abstract A general sorting algorithm, having the well knownO(n 2) algorithmsStraight Insertion Sort andSelection Sort as special cases, is described. This algorithm is analyzed in the case that certain choices in the algorithm are done randomly, and this yields an algorithm that has an average complexity ofO(n 1.5) and a worst case complexity ofO(n 2). However, making random choices (by some random number generator) is time consuming, and a simple “quasi-random” scheme is therefore implemented. Test runs indicate that also this version has average complexity ofO(n 1.5), and it even seems to perform better than the version using real random choices (even if we disregard the time used for the random choices). This version also needs very little administrative overhead, and it therefore compares favourably to many other sorting algorithms for small and medium sized arrays.

    Observation of rotational rainbow scattering in atom-triatomic molecule collisions: K, Rb-CO2 (1985)

    Notes: Abstract Rotational rainbow scattering has been measured in the systems K- and Rb-CO2 at collision energies 0.17≦E≦0.56 eV and CMS angles 110°≦ϑ≦170°. The ellipsoidal hard shell anisotropy of the normal (repulsive) potentials is evaluated to be (c−a)=0.67Å in K−CO2, (c−a)=0.63Å in Rb−CO2, averaged over a slight energy dependence. Below an apparent activation thresholdE a≅0.23 eV, nearly equal in both systems, the scattering largely conforms to that of diatomic molecules, indicating linear, rigid rotor type behaviour as the dominant collisional response of triatomic CO2. AboveE a characteristic, eventually drastic distortions set in. They are probably caused by intermediary charge transfer which activates a complex, coupled vibrational, rotational motion inM +-CO 2 − , altering the outcome of the collisions altogether. The simple model of a partially absorptive, hard shell is used to find that some gross features of the distortions are consistent with distinct properties of the acceptingelectronic orbital 6a 1 in CO 2 − .
