Potentiodynamic cyclic polarization of four orthodontic alloys (wires), namely Permachrome, Elgiloy, a beta-titanium alloy and Nitinol in a 1% NaCl solution within -500 mV and +300 mV (SCE) indicated the first three alloys to be passive whereas breakdown of passivity was observed on Nitinol. The SEM examination of the…

Four basic lead carbonates were prepared and identified by X-ray powder diffractometry. These were hydrocerussite (Pb 3 (OH) 2 (CO 3 ) 2 ), plumbonacrite (Pb 10 O(OH) 6 (CO 3 ) 6 ), and the two adducts MOH•2PbCO 3 (M = Na, K). New diffraction data are presented for the latter two compounds; they both have primitive he…

The pharmacokinetics of iohexol, a new nonionic, water-soluble contrast medium, have been determined after intravenous injection in 20 healthy volunteers, at four different dose levels (125-500 mg I/kg). The apparent volume of distribution was 0.27 1/kg, indicating distribution in the extracellular water. The biologic…
The infrared and Raman spectra of disordered paraelectric and ordered ferroelectric phases of CsH2PO4 and CsD2PO4 single crystals have been investigated at various temperatures in the 4000–10 and 4000–0 cm−1 range, respectively. An assignment of lattice and internal vibrations in terms of symmetry species and approxim…
The thermal expansion behavior of lithium, sodium, potassium, and rubidium borate glasses was measured. The results indicate that the “borate anomaly” in the thermal expansion coefficient occurs at ∼20 mol% alkali oxide. A maximum in the glass transformation and dilatometric softening temperatures also occurs at ∼27 m…
Using mean field free energy functionals of the type employed by Sullivan, we have investigated the nature of the transition from partial to complete wetting that occurs at a solid-gas interface. We show that this wetting transition can be a first or a second order phase transition. If it is first order, as predicted…
The role of water vapor in crystallite growth and the tetragonal‐to‐monoclinic phase transformation of ZrO 2 was studied using three specially prepared samples: an ultrafine powder of monoclinic ZrO 2 obtained by hydrolysis of ZrOCI 2 , an aggregated powder of tetragonal ZrO 2 obtained by thermal decomposition of Zr(O…

We studied the attachment of a number of freshwater bacteria from River Sowe, Coventry, England, to test substrata. The attachment of each organism to hydrophobic and hydrophilic surfaces was evaluated, and further studies evaluated the attachment of selected isolates to a number of substrata with a range of water wet…
Previous work has shown that the permanent adhesive of the marine mussel Mytilus edulis is a protein containing large amounts of hydroxyproline (13%) and 3,4-dihydroxyphenylalanine (Dopa, 11%). The protein also known as the polyphenolic protein is produced and stored in the exocrine phenol gland of the mussel and depo…
The present paper points out the importance of three main subjects concerning the presence of sulphur compounds in concrete: i) the maximum sulphate content of concrete aggregates specified in the Spanish concrete standard; ii) the standardized analytical method to determine sulphur compounds in aggregates for concret…
In the present paper, third of the new series started with and industrial portland cement, there is studied the influence exerted by the addition of different quantities of slag to an industrial portand cement (cement 3 < > P-450) in its chemical-resistant behavior when subjected, during various periods of time, to th…

Monte Carlo calculations for the restricted primitive model at a point in the molten salt region have been made using a variety of summation methods. The empirical conclusion is that the Ewald summation is an excellent method for this work. It is shown that it does not produce significantly anisotropic pair distributi…
In this research the process of formation of a low energy clinker is studied, when fly-ashes (rich in sulphates and lime) and fluorspar are used as raw materials (fly-ashes replaces to the tradicional raw mix partially). The availability of those fly-ashes is shown since clinker at 1.340 °C is obtained. The mineralogi…
