Characterization of Ce0.9Gd0.1O1.95 powders synthesized by spray drying

Ce_0.9Gd_0.1O_1.95 powders were synthesized by spray drying and successive calcinations. The phase purity, BET surface area, and particle morphology of as-sprayed and calcined powders were characterized. After calcination above 300 °C, the powders were single phase and showed a BET surface area of 68 m²/g when calcined at 300 °C. The conductivity, in air, of sintered pellets was measured by electrochemical impedance spectroscopy (EIS) and it was found to be comparable with literature values. The activation energy for the total conductivity was around 0.83 eV. The powder calcined at lower temperature showed better sinterability and higher total conductivity due to an increased bulk conductivity.     

Review of Coping strategies therapy for bulimia nervosa.

Reviews the book, Coping strategies therapy for bulimia nervosa by David L. Tobin (see record 2000-07256-000). The book starts with a short introduction of the need for combination treatments and the obstacles therapists have to overcome in order to arrive at a cost-effective care for bulimic patients. The first part of the book provides a framework for coping strategies therapy (CST). The author reviews empirical and theoretical models of psychotherapy. This discussion is followed by an overview of CST, with short summaries of the different doses of therapy that are a central outcome of the author's work. The second part of the book is an elaboration of the details of the different doses of therapy: Dose 1 (problem engagement with a "remoralizing" aim; 1-2 sessions), Dose 2 (problem engagement with a "remediating" aim; 3-8 sessions), Dose 3 (emotion engagement with a rehabilitating aim; 9-20 sessions), and Dose 4 (problem and emotion disengagement with the aim of "rooting out the source of the disease"; 50-100+ sessions). Each dose is a separate treatment program designed for a specific bulimic patient group, and each has a specific aim and starts at a specific level of motivation for change. Basic aims for the author are to justify the broad range of activities on a theoretical and empirical basis, to organize those activities to help clinicians make rationally administered interventions, to provide a rationale for combining diverse interventions, and to build an informed basis that facilitates clinical care. These are far-reaching aims, and the reviewer thinks Tobin takes a large and interesting step toward a more integrative understanding and practical approach to the treatment of eating disorders.

Post-mortem metabolism in fresh porcine, ovine and frozen bovine muscle

After slaughter, beef carcasses (n = 20) in groups of two were subjected to five treatments (one side only) including intermittent spray-chilling using water, 1% acetic acid or 1% lactic acid, or a single spray treatment with 1% acetic acid or 1% lactic acid. Intermittent spray-chilling consisted of two sprays of 30 s duration per hour for 12h. Single spray treatment consisted of one 30 s spray after entering the chill cooler. The other side of each carcass (control) was air chilled (at 2 to 3°C; air velocity 1 to 3 m/s) only. Five subprimal cuts were taken from each side at 48 h post mortem, vacuum packaged and stored for 28 days at 2°C. Intermittent sprays of sides with acetic or lactic acid resulted in significant (1.8-4.3 log/cm(2)) reductions in aerobic plate count of the strip loin, boneless rib and clod over their controls after these subprimal cuts had been vacuum packaged and stored for 28 days at 2°C in high-oxygen barrier (HOB) film. Lactobacillus spp. were dominant in the microflora of the subprimals from the control and treated sides. When sides were treated with a single sprays of acid, significant reductions in APC were noted only for some cuts of sides treated with lactic acid. After 28 days of storage, there were few significant differences in percentage purge, lean color, and off-odor scores between subprimals from control and treated sides.

Systemic methotrexate toxicity. A pharmacological study of its occurrence after intrathecal administration in a patient with renal failure

Methotrexate pharmacokinetic studies, performed on a patient with renal impairment who had toxic effects following 20 mg/sq m of intrathecally administered methotrexate, demonstrated prolonged serum concentrations of the drug, which accounted for the condition. After the return of normal renal function, pharmacokinetic studies were repeated following the same dose and route of administration of methotrexate. On this occasion there was a rapid clearance of serum methotrexate below toxic levels.     

The parallel implementation of the one-dimensional Fourier transformed Vlasov-Poisson system

A parallel implementation of an algorithm for solving the one-dimensional, Fourier transformed Vlasov-Poisson system of equations is documented, together with the code structure, file formats and settings to run the code. The properties of the Fourier transformed Vlasov-Poisson system is discussed in connection with the numerical solution of the system. The Fourier method in velocity space is used to treat numerical problems arising due the filamentation of the solution in velocity space. Outflow boundary conditions in the Fourier transformed velocity space removes the highest oscillations in velocity space. A fourth-order compact Padé scheme is used to calculate derivatives in the Fourier transformed velocity space, and spatial derivatives are calculated with a pseudo-spectral method. The parallel algorithms used are described in more detail, in particular the parallel solver of the tri-diagonal systems occurring in the Padé scheme.

An energy condition for initiation of interfacial microcracks at inclusions

Fracture mechanics is applied to the problem of microcrack initiation on cylindrical (spherical) particles in a matrix. The numerical calculations have been performed by the finite element method.A stress criterion for the initiation of interfacial, cap shaped, microcracks is derived as function of inclusion size and bonding strength. It is found that the cracks are unstable below a minimum “cap angle”. Comparison with experiments shows reasonable quantitative agreement.
