—Position awareness in unknown and large indoor spaces represents a great advantage for people, everyday pedestrians have to search for specific places, products and services. In this work a positioning solution able to localize the user based on data measured with a mobile device is described and evaluated. The position estimate uses data from smartphone… (More)
Proeulia triquetra Obraztsov (Lepidoptera: Tortricidae) is an occasional pest in fruit orchards in central-southern Chile. In order to develop species-specific lures for detection and monitoring of this species, we identified the female-produced sex pheromone. (Z)-11-Tetradecenyl acetate (Z11-14:OAc), (E)-9-dodecenyl acetate (E9-12:OAc), and… (More)
Insulin secretion and insulin sensitivity indexes are related by hyperbolic functions, allowing the calculation of the disposition index (DI) as the product of the acute insulin response (AIR) and the insulin sensitivity index (Si) from intravenous glucose tolerance test (IVGTT). Our objective was to develop an oral-DI based on the oral glucose tolerance… (More)
The electronic structure of a Mn(II) ion bound to highly oxidizing reaction centers of Rhodobacter sphaeroides was studied in a mutant modified to possess a metal binding site at a location comparable to the Mn4Ca cluster of photosystem II. The Mn-binding site of the previously described mutant, M2, contains three carboxylates and one His at the binding… (More)
The title compound, C(14)H(17)NO(5)S, was prepared by oxidation of (2R,3S,4R)-2-phenyl-sulfonyl-methyl-1-hy-droxy-3,4-iso-pro-pyl-idene-dioxy-pyrrolidine. Its crystal structure confirms unequivocally its configuration. Two inter-molecular C-H⋯O inter-actions help to establish the packing.
The title compound C(7)H(11)NO(3) was prepared by intra-molecular nucleophilic displacement of 2,3-O-iso-propyl-idene-d-erythronolactol. There are two mol-ecules in the asymmetric unit, which are related by a pseudo-inversion centre. The crystal structure determination confirms unequivocally the configuration of the chiral centres as 3S,4R. In the crystal… (More)
The synthesis of a new chiral pyrrolidine has been performed using 2,3-O-isopropylidene-D-erythronolactol as a suitable starting material.
We have used chemical vapor deposition (CVD), for the synthesis of carbon nanotubes (CNTs) by the sublimation of iron phthalocyanines (FePcs); by the catalytic decomposition of acetylene over iron nanoparticles, supported on a thermal Si oxide and also by a Pd catalyst supported on alumina. We have explored different means of growing multiple wall CNTs and… (More)
