More than just a Green Façade: Vertical Gardens as Active Air Conditioning Units
No full textAbstractThis paper explores the potential of a vertical garden to function as an active evaporative cooling air conditioning unit. It builds on previous work by Davis, Ramirez and Vallejo [1]. This study shows the results of a full scale, building incorporated vertical garden that measured 1.5 m wide by 2.8 m high. Air flowed behind the garden substrate, where it was cooled and humidified as it flowed down the back of the garden through its contact with the humid surface. The experimental results were compared to the mathematical model developed by Davis and Hirmer [2]. Overall, it was suspected that variations in ambient temperatures during the measurements taking process had a major influence on the results. In taking the data considered most reliable into account however, the results of the mathematical model end experimental data were within 0.44°C. The results indicate that such gardens show great promise for building climate control, but where further research is needed in order to mitigate the influence of fluctuations in ambient temperatures

An Adaptive Control Strategy for Dynamic Response of an Autonomous DC system
No full textThe dynamic behaviour - steady-state and transient - of the DC Microgrids during power disturbance can affect the system’s general performance. A hybrid combination of energy storage devices with slow frequency response, like a Fuel Cell, and with a fast dynamic response, like a Super-Capacitor, provides an improved dynamic response to stabilise DC bus voltage. However, control parameters should be designed based on the preferences of the system. This paper proposes a fuzzy-based controller to determine the Virtual Capacitor Droop controller to achieve the desired transient response. The proposed dynamic control method is validated through MATLAB/Simulink.Accepted author manuscriptDC systems, Energy conversion & StorageOrganisation & Governanc

Differential susceptibility of poplar hybrids to the aphid Chaitophorus leticomelas (Homoptera : Aphididae)
No full textRamirez, C.C. (reprint author) Instituto de Biología Vegetal y Biotecnología, Universidad de Talca, Casilla 747, Talca, Chile.Zamudio, F. Facultad de Ciencias Forestales, Universidad de Talca, PO Box 747, 2 Norte 685, Talca, Chile.After its recent introduction to Chile, the aphid Chaitophoris leucomelas Koch is becoming a serious pest affecting commercial poplar, Populus spp., plantations. The pattern of natural infestation of C. leucomelas among poplar hybrids with different pedigrees and the aphid intrinsic rate of increase (r(m)), of C. leucomelas were assessed in the field. In most of the hybrids, aphid abundance peaked in March (late summer). Among 12 types of poplar- crosses, [(P. trichocarpa Torr. & Gray x P. deltoides Bartram ex Marshall) x (P. trichocarpa x P. deltoides)] and [(P. trichocarpa x P. mowiczii Henry) x P, maximowiczii] showed the highest and lowest aphid densities: respectively. A trend to find more aphids in branch bases was apparent. The intrinsic rate of C. leucomelas increase was higher in [(P. trichocarpa x P. deltoides) x P. deltoides] hybrids. and lower in [(P. trichocarpa x P. maximmowiczii) x P. trichocarpa] hybrids. Aphid density and perfomance were higher in hybrids with P. deltoides parentage. whereas hybrids with P. maximowiczii parentage showed lower aphid densities and performance. Hybrids with P. nigra L. parentage, namelly, [P. trichocarpa x P. nigra] also had high aphid density, but aphid performance was lower compared with hybrids with P. deltoides parentage. These results suggest that among poplar hybrids studied. susceptibility to G. leucomelas is inherited through P. deltoides, whereas resistance seems to be inherited through P. maximowiczii. Thus, P. maximowiczii hybrids are recommended for commercial or ornamental planting programs in zones where there is a high risk of aphid infestation
Use of estradiol-BSA conjugates to characterize membrane estrogen binding sites in brain cells: Biochemical and physiological studies
No full textRapid nongenomic actions of estrogen probably involve one or several membrane estrogen receptors/binding proteins, which are different from classical estrogen receptor (ER). Specific membrane binding sites for estrogen (mEBS) in female rat brain were demonstrated by a novel and sensitive radioligand binding assay using 17-estradiol covalently linked with (\sp{125}I) -labeled bovine serum albumin (17-E-6- (\sp{125}I) BSA conjugate), as a ligand. These membrane binding sites (dissociation constants of 3-34 nM and total binding sites of 3-40 pmol/mg protein) in crude synaptosomal fractions (P2) from hypothalamus, olfactory bulb, and cerebellum show distinct binding specificity from classical ER. To establish if the mEBS identified by 17-E-6- (\sp{125}I) BSA represent putative membrane estrogen binding proteins, a ligand blotting technique was used. Three major binding proteins with molecular weights of about 23, 28, and 32 kDa, and three additional proteins (18, 40, and 130 kDa), were specifically labeled. The 23 and 40 kDa proteins were concentrated in mitochondrial fractions (mP2) whereas 18, 28, and 32 kDa proteins were enriched in microsomal fractions (P3). One of these membrane estrogen binding proteins (23 kDa) was purified from digitonin-solubilized P2 fractions by affinity columns coupled with 17-E-6-BSA and was identified as the oligomycin-sensitivity conferring protein (OSCP), a subunit of the F\sb0F\sb1 ATP-synthase/ATPase required for the coupling of a proton gradient across the F\sb0 sector of the mitochondrial membrane to ATP synthesis in the F\sb1 sector. OSCP, therefore, represents an estrogen target site in addition to ER in the cells and may play an important role in estrogen-induced changes in cell energy metabolism. The unlabeled ligand, 17-E-6-BSA (1-100 nM), was biologically active in rapidly facilitating the release of dopamine from corpus striatum, an important estrogen target site that lacks classical ER. This rapid action of estrogen is consistent with the presence of mEBS in the plasma membranes of these cells and future work is ongoing to purify this putative mEBS and/or clone its cDNA.Made available in DSpace on 2011-05-07T13:19:27Z (GMT).

The electronic structure calculations were done using the M062X hybrid exchange-correlation functional in conjunction with the 6-31G** basis sets for oxygen and hydrogen. For the iodine and samarium atoms the Stuttgart Koln relativistic effective core potentials were utilized with their associated valence basis sets. Starting from the optimized geometry of SmI2 embeded in the microsolvation environment, we find a swift substitution of the iodine ions by eight tightly bound water molecules around Sm(II). Through the Sm-O radial distribution function and the evolution of the Sm-O distances, the present study predicts a first rigid Sm(II) solvation shell from 2.6,to 3.4 (A) over circle, whose integration leads to a coordination number of 8.4 water molecules, and a second softer solvation sphere from 3.5 to ca. 6 (A) over circle. The Sm(II)-O radial distribution function is in excellent agreement with that reported for Sr2+ from:EXATS studies, a fact that can be explained because Sr2+ and Sm2+ have almost identical ionic radii (ca. 1.26 (A) over circle) and coordination numbers: 8 for Sr2+ and 8.4 for Sm2+. The theoretical EXAFS spectrum was obtained from the BOMD trajectory and is discussed in the light ofthe experimental spectra for Sm(III). Once microsolvation is achieved, no water exchange events were found to occur around Sm2+, in agreement with the experimental data for Eu2+ (which has a nearly identical charge-to-ionic radius relation as Sm2+),-where the mean residence time of a water molecule in [Eu(H2O)(8)](2+) is known to be ca. 230 ps
