Autosuficiència energètica. Estudi pilot a Alinyà (Alt Urgell)

A aquest estudi s'ha analitzat si és viable l'autosuficiència energètica en base a un estudi pilot al nucli rural d'Alinyà aprofitant els recursos naturals de la zona. S'ha realitzat un estudi del consum energètic de la població i s'ha comparat amb el potencial de producció energètica dels recursos renovables locals incloent energia provinent de la biomassa i aprofitada en calderes individuals per a cada habitatge, energia solar en teulades i energia hidroelèctrica a partir de centrals minihidràuliques restaurades ja existents. També s’ha realitzat un anàlisi per detectar possibles factors d’ineficiència energètica i a partir d’aquí, proposar una sèrie de mesures per corregir aquesta. S'han comptabilitzat les emissions de CO2 derivades del consum energètic i les proporcions que representa cada tipus de font energètica sobre el total del nucli. També s'ha establert una comparativa del consum mitjà per habitant i any entre la població i Catalunya; el consum a Alinyà és d'1,46 Tep's, mentre que el de Catalunya és d'1,7 Tep's, el nostre estudi no contempla la mobilitat, si se li resta aquest vector a la mitjana de Catalunya veiem que és de 0,9 Tep's, per tant, hi observem un major consum energètic. El 76% del consum d'Alinyà prové dels combustibles fòssils, concretament del gasoil, el nucli té una forta dependència respecte a aquesta energia, que a més a més representa el 86% (56T CO2 eq.) de les emissions totals de CO2. Per finalitzar, s'ha demostrat que és possible assolir l'autosuficiència energètica mitjançant l'implantació d'una combinació d'estratègies, viables en tots els aspectes; tant tècnics com socioeconòmics. Abastint el poble d'energia a un menor cost econòmic i amb un estil de vida més respectuós amb el medi ambient.

Basis set superposition error-counterpoise corrected potential energy surfaces : application to hydrogen peroxide ... X (X=F-, Cl-, Br-, Li+, Na+) complexes

Møller-Plesset (MP2) and Becke-3-Lee-Yang-Parr (B3LYP) calculations have been used to compare the geometrical parameters, hydrogen-bonding properties, vibrational frequencies and relative energies for several X- and X+ hydrogen peroxide complexes. The geometries and interaction energies were corrected for the basis set superposition error (BSSE) in all the complexes (1-5), using the full counterpoise method, yielding small BSSE values for the 6-311 + G(3df,2p) basis set used. The interaction energies calculated ranged from medium to strong hydrogen-bonding systems (1-3) and strong electrostatic interactions (4 and 5). The molecular interactions have been characterized using the atoms in molecules theory (AIM), and by the analysis of the vibrational frequencies. The minima on the BSSE-counterpoise corrected potential-energy surface (PES) have been determined as described by S. Simón, M. Duran, and J. J. Dannenberg, and the results were compared with the uncorrected PES

Transient prenatal expression of NPY-Y1 receptor in trigeminal axons innervating the mystacial vibrissae.

Using immunohistochemistry in combination with confocal laser scanning microscopy, we studied the ontogeny of neuropeptide Y-Y1 receptor (Y1-R) expression in the trigeminal system of the rat. The study was limited to the nerve fibers innervating the mystacial pad and the trigeminal ganglia. In the trigeminal ganglia, Y1-R-immunoreactive (IR) neurons were first observed at E16.5. At this same stage some nerve fibers in the trigeminal ganglia also exhibited Y1-R-like immunoreactivity (LI). Strongly Y1-R-IR nerve fibers innervating the follicles of the mystacial vibrissae were first observed at E18. After double labeling, the Y1-R-LI was found to be colocalized with the neuronal marker protein gene product 9.5. At P1 only weak labeling for the Y1-R was found around the vibrissae follicles, whereas the neurons in the trigeminal ganglia were intensely labeled. The same was true for the adult rat, but at this stage no Y1-R labeling at all was observed in nerve fibers around the vibrissal follicles. These results strongly support an axonal localization of the Y1-R at this developmental stage. The transient expression of the Y1-R during prenatal mystacial pad development suggests a role for the Y1-R in the functional development of the vibrissae.

The E3 ubiquitin ligase Itch regulates sorting nexin 9 through an unconventional substrate recognition domain.

The level of intracellular proteins is mainly regulated through modifications by ubiquitin ligases that target them for degradation. Members of the NEDD4 family of E3 ubiquitin ligases, such as Itch (atrophin-1 interacting protein 4), possess up to four WW domains for specific association with PY motif-containing substrates. We have identified sorting nexin 9 (SNX9), a protein involved in endocytic processes, as a new substrate of Itch. Itch ubiquitylates SNX9 and regulates intracellular SNX9 levels. Using truncated proteins, we found that the interaction with SNX9 is mediated by the proline-rich domain (PRD) of Itch, a domain distinct from the conventional WW recognition domain, and the SH3 domain of SNX9. Interaction with the PRD of Itch is essential for SNX9 ubiquitylation and degradation. Furthermore, this effect is specific for Itch, as NEDD4, a related PRD-containing E3 ligase, does not bind SNX9. SNX18, a second member of the SNX family containing an SH3 domain, was also found to bind to Itch. Our results indicate that the pool of substrates of NEDD4 family E3 ubiquitin ligases extends beyond proteins containing PY motifs.
