Astrocyte heterogeneity in the brain: from development to disease
In the last decades, astrocytes have risen from passive supporters of neuronal activity to central players in brain function and cognition. Likewise, the heterogeneity of astrocytes starts to become recognized in contrast ...
Development of heterogeneous node network using microcontroller with protocols CAN and Zigbee
In this paper was proposed the development of an heterogeneous system using the microcontroller (AT90CANI28) where the protocol model CAN and the standard IEEE 802.15.4 are connected. This module is able to manage and ...
Analysis of catalytic potential of a new heterogeneous catalyst in the preparation of biodiesel
In this work was investigated the catalytic potential of a new heterogeneous catalyst of stoichiometry Ca0.5K0.5TiCu0.25O3, with double perovskite structure, in the preparation of biodiesel via ethylic route. The catalyst ...
Dynamic coordination among heterogeneous agents
We study a dynamic model of coordination with timing frictions and payoff heterogeneity. There is a unique equilibrium, characterized by thresholds that determine the choices of each type of agent. We characterize equilibrium ...
Boundary Tension at the Interface of Nanoscopic Helium Films on an Heterogeneous Substrate
This paper reports the first calculation of the two-dimensional interfacial profile and energetics of nanoscopically thin films of helium, on an heterogeneous planar substrate consisting of two adjoining metals. The ...

Essa tese é constituída por três artigos: 'Tax Filing Choices for the Household', 'Optimal Tax for the Household: Collective and Unitary Approaches' e 'Vertical Differentiation and Heterogeneous Firms'.
Convenient synthesis of ketal derivatives from cubebin using amberlite as heterogeneous catalyst
Eleven ketal derivatives were prepared from the natural product cubebin using Amberlite IR-120AR as heterogeneous catalyst and ROH as the source of the alkyl group.
Comsumption Decisions in an Economy with Heterogeneous Preferences defined by a Bivariate Distribution.
(B. Preissl, 2013-04-16)
This paper considers an economy populated by heterogeneous individuals in two respects: both parameters representing the subjective discount and the risk aversion rates are supposed to have a joint distribution. That is, ...
Heterogeneous catalysis afford biodiesel of babassu, castor oil and blends
This work describes the preparation of babassu, castor oil biodiesel and mixtures in various proportions of these oils, using alkaline compounds of strontium (SrCO3 + SrO + Sr (OH)2) as heterogeneous catalysts. The mixture ...
