Earlier Sagdeev pseudopotential treatments of ion-acoustic double layers in plasmas with two electron populations were based on a model in which both electron densities were described by isothermal Boltzmann distributions. Using a more recent fluid-dynamical approach, with polytropic equations of state indices gamma(j), one finds analytically that no double layers can be formed for gamma(j)>= 3/2, due to total rarefaction of the cooler electrons or infinite compression of the ions. For gamma(j)< 3/2, rarefactive double layers occur, but, just below 3/2, at unrealistically small cool electron densities or large Mach numbers. As gamma(j) decreases towards 1, these constraints become less restrictive and go over smoothly to those known from Boltzmann studies. Contrary to what appears in the literature, very weak compressive double layers can also be found for Boltzmann electrons, but only for soliton conditions barely above the existence threshold; i.e., marginally super-ion-acoustic. Any slight increase in the critical Mach number destroys the possibility of having positive double layers, and, within the limits of numerical accuracy, no window could be found for gamma(j)not equal 1, where compressive double layers exist.(c) 2006 American Institute of Physics.

This paper studies the design of a pay-as-you-go social security system in an overlapping generations model where fertility is in part stochastic and in part determined through capital investment. If investments are publicly observable, pension benefits must be linked positively to the level of investment, and payroll taxes negatively to the number of children. The outcome is characterized by full insurance with all parents, regardless of their number of children, enjoying identical consumption levels. Without observability, benefits must increase, and payroll taxes decrease, with the number of children. The second-best level of investment, and the resulting average fertility rate, are less than their corresponding first-best levels. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

The aim of the current paper was to elaborate an immobilization method of thrombin receptor agonist peptide (TRAP-6) in biodegradable biocompatible poly(d,l)-lactide-co-glycolide (PLGA) inicroparticles and to demonstrate the effect of the entrapped peptide for tissue repair, namely,for a gastric ulcer treatment in rats. TRAP-6 was entrapped in polymer using w/o/w double emulsion-evaporation technique. The morphology of empty and TRAP-6 loaded microparticles was evaluated by light and scanning electron microscopy (SEM). In vitro release kinetics profile of TRAP-6 from microparticles was studied by HPLC. To investigate gastric mucosal protection effect in vivo, TRAP-6-loaded microparticles were administered in a rat stomach after a previous mucosal injury (a gastric ulcer). Microparticles with entrapped TRAP-6 were found to reduce both an inflammation and proliferation phases of wound healing, and thus accelerated tissue repair in rats. [less ▲]

In Medical Microbiology, in addition to the direct methods of indentification of infectious agentss, the serologic indirect techniques by quantification of antibodies have extremely useful in infectiology, for the diagnosis and the therapeutic or vaccination follow-up as well as for epidemiologic enquiries, serodiagnosis methods have significantly improved. Meanwhile, results may reveal hard to interpret, especially when are tries to specify the time of the beginning of an infection. The results require in the majority of the cases to be compared on two subsequent serum samples, to observe a possible increase in antibodies level. In addition, the infectious serology results may not be considered as the only element of final diagnosis. In all cases, they have to be interpreted and challenged against the clinical context.

A field experiment designed to assess the biodiversity related to nettle strips closed to crops, and more particularly the aphid and related beneficial populations, was established in experimental farm located in Gembloux (Belgium). Margin strips of nettle (Urtica dioica) closed to wheat (Triticum aestivum), green pea (Pisum sativum) and rape (Brassicae napus) fields were investigated. The diversity, abundance of aphids and related predators were analysed according to the plant crop species and the differential pesticide application (treated plot and control). Insects were visually observed every week during all the cultivation season. Two main families of aphidophagous predators were found in all field crops and nettle, the Coccinellidae and Syrphidae. The diversity of the aphidophagous predators was shown to be higher on nettle than in field crops, particularly the Chrysopidae, the Anthocoridae and the Miridae. However, a striking difference of ladybird abundance was observed according to the aphid host plant. In one side, Coccinella septempunctata was much more abundant on Acyrthosiphon pisum infested green pea than on the other host plant species. At the opposite, higher occurrence of Harmonia axyridis was observed on the aphid infested nettle plants than on the crop plants. In particular, none of H. axyridis was found in wheat crop. Also, more than only a significant positive correlation between predator and aphid abundance, specialised relations between particular aphid species and some so-called generalist predators was determined in the fields. Finally, intraguild interactions between the aphidophagous predators was assessed and shown that only a significant negative correlation between Episyrphus balteatus and H. axyridis related to the nettle aphid, Micrlophium carnosum, was observed. The relative distribution of the ladybirds, namely C. septempunctata and H. axyridis according to the host plant, nettle strips and crop plots was discussed in relation to integrated pest management approach.

The Venus airglow has been observed from spectrometers on board rockets probes and satellites such as OUVS on Pioneer Venus Venera Galileo HUT on the Space Shuttle and quite recently SPICAV on Venus Express The spectrum is dominated by emissions from helium hydrogen oxygen and carbon lines and CO bands Localized emissions of OI at 1304 and 1356 A have been sporadically observed on the nightside and are likely caused by precipitation of auroral electrons in the wake of the planet We have developed a Monte Carlo code solving the Boltzmann equation for energetic electrons to calculate the energy distribution function and fluxes of primary and secondary auroral electrons and for photoelectrons The model is used to calculate the vertical distribution of the excitation rate of various excited states For optically thick transitions such as the 3P-3S triplet at 1304 A a radiative transfert code is used to calculate the emergent emission rate We find that the relative intensity of the oxygen and CO Cameron band emissions is a sensitive indicator of the energy of auroral electrons The observed values indicate that the mean energy is on the order of 10-50 eV Dayglow intensity and distributions are also compared with observed characteristics [less ▲]

Rochet (1991) showed that with distortionary income taxes, social insurance is a desirable redistributive device when risk and ability are negatively correlated. This finding is re-examined when ex post moral hazard and adverse selection are included, and under different informational assumptions. Individuals can take actions influencing the size of the loss in the event of accident (or ill health). Social insurance can be supplemented by private insurance, but private insurance markets are affected by both adverse selection and moral hazard. We study how equity and efficiency considerations should be traded off in choosing the optimal coverage of social insurance when those features are introduced. The case for social insurance is strongest when the government is well informed about household productivity. [less ▲]
