A stochastic lattice model for the simulation of sandpiles is presented. The model allows for the numerical investigation of the phase segregation phenomenon occurring when different granular species are initially mixed together before deposition. The model includes the collective motion of grains along the pile surface and produces the so-called landslides. The parameters of the model are discussed. The distribution of avalanche sizes is found to broaden when the number of grain types increases. This result raises new questions about previously reported experimental observations of avalanche size distributions. [less ▲]

In the course of their disease certain patients with frontotemporal dementia (FTD) develop clinical features compatible with a motor neuron disease (FTD-MND). Previous reports have suggested that the functional pattern is similar in FTD and FTD-MND. However, some neuropathological studies suggest greater involvement of medial temporal regions in FTD-MND than in FTD. Using statistical parametric mapping (SPM96), we compared the metabolic patterns obtained at rest with positron emission tomography in 10 FTD patients and three FTD-MND patients with those obtained from 46 healthy subjects (HS). Mean age, duration of illness and dementia stage did not differ statistically between the FTD and FTD-MND groups. In comparison with HS, both groups showed frontal and anterior temporal hypometabolism at P<0.001. When the FTD-MND group was compared to the FTD group, significant hypometabolism was only observed in bilateral amygdala, bilateral hippocampus, and bilateral enthorinal and parahippocampal regions (Brodmann's areas, BA 28/36) at P<0.005. We found no significant differences in regional glucose uptake when FTD patients were contrasted to FTD-MND patients. Our results suggest statistically comparable frontal and lateral temporal hypometabolism in both conditions but greater impairment of medial temporal lobe activity in FTD-MND. Our results and a review of the literature support the hypothesis that there is a functional continuum between classical motor neuron disease (cMND), FTD-MND, and FTD. [less ▲]

The pregnancy-associated glycoprotein (PAG) concentration profiles of goats that had been experimentally inoculated with either Toxoplasma gondii or Listeria monocytogenes are described. All goats were examined regularly by ultrasonography. In T. gondii-infected females (n = 5), a slow decrease of PAG was observed throughout a period of 55 to 74 d after inoculation. Afterwards, the goats either aborted (n = 4) or kidded 1 dead and 1 weak fetus (n = 1). In L. monocytogenes-infected females (n = 8), a marked decrease of PAG was observed from the day of inoculation. Abortion occurred within 9 to 11 d post inoculation (n = 7). Only 1 goat kidded a healthy fetus. [less ▲]

Diblock copolymers of 4-vinylpyridine (4VP) and sodium methacrylate (MANa) have been synthesized and tested as dispersants for aqueous dispersions (80 wt % solid) of alumina-coated titanium dioxide. P4VP is strongly anchored onto the pigment surface. The molecular composition of the block copolymers has an effect on the amount of copolymer required for imparting good stability to the slurry. Where the two parent triblock copolymers are concerned, triblocks consisting of PMANa outer blocks have a stabilizing efficiency comparable to the diblock copolymers, whereas the reverse structure is much less efficient. In the case of a nonblock distribution of 4VP and MANa in the copolymer chains, the stabilization effect is lost. Finally, the comparison of different stabilizing blocks attached to the same anchoring block confirms that the electrosteric stabilization mechanism is superior to the steric stabilization mechanism. A decrease in the anchoring strength of the diblocks has a deleterious effect on the dispersion stability. [less ▲]

A one--dimensional model has been developed to investigate the links between auroral heat input and the atmospheric temperature and composition structure of Jupiter. Different energy distributions are used to evaluate the importance of the energy spectrum of the incident electrons for the thermal balance of Jupiter's auroral thermosphere. Radiative cooling by H_3(+) and hydrocarbon (CH_4, C_2H_2) and downward conduction are calculated to solve the heat conduction equation. The values of observable quantities such as the altitude of the H_2 emission peak, infrared (IR) and ultraviolet (UV) emissions and temperatures associated with H_2 and H_3(+) optical signatures are used to constrain the parameters of the auroral electron energy distributions. From these simulations, it appears that the precipitated auroral energy is not able to directly provide the necessary heat to balance the hydrocarbon cooling below the homopause. It is suggested however that the auroral upper stratosphere is warmer than the equatorial upper stratosphere measured by Galileo. A Maxwellian energy distribution with a total flux of 20 ergs cm(-2) s(-1) and a characteristic energy of 22 keV added to a soft Maxwellian component of 1 erg cm(-2) s(-1) and 350 eV produces results in good agreement with thermospheric observations.
