The influence of BHA, BHT and TBHQ on the oxidation stability of soybean oil et...
Domingos,Anderson K.; Saad,Emir B.; Vechiatto,Wellington W. D.; Wilhelm,Helena M.; Ramos,Luiz P.The effect of synthetic antioxidants such as BHT (butyl-hydroxytoluene), BHA (butyl-hydroxyanisol) and TBHQ (t-butyl-hydroxyquinone) was evaluated on the induction time of soybean oil ethyl esters with low oxidation stability, employing the Rancimat method (EN14112). Interaction effects were also investigated by employing a 2³ factorial design, which had as minimum and maximum levels the concentrations of zero ...
Distribuição e amostragem de Sitophilus zeamais (M.) em grãos de trigo armazena...
Santos,Anderson K.; Faroni,Lêda R. D’Antonino; Santos,Jamilton P. dos; Guedes,Raul N. C.; Rozado,Adriano F.O objetivo deste trabalho foi encontrar, em uma massa de grãos, o tipo de distribuição populacional de Sitophilus zeamais (Mostch., 1895) e calcular o número de amostras necessárias para um programa de monitoramento dessa praga. Utilizou-se um silo metálico com 12,5 t de trigo tipo durum, da safra de setembro/1998. Durante o carregamento do silo, o trigo foi infestado com S. zeamais, de tal forma que obtivesse ...
Hadron energy reconstruction for the ATLAS calorimetry in the framework of the ...
Akhmadaliev, S.; Amaral, P.; Ambrosini, G.; Amorim, A.; Anderson, K.; Andrieux, M. L.; Aubert, B.; Augé, E.; Badaud, F.; Baisin, L.; Barreiro, F.This paper discusses hadron energy reconstruction for the ATLAS barrel prototype combined calorimeter (consisting of a lead-liquid argon electromagnetic part and an iron-scintillator hadronic part) in the framework of the non-parametrical method. The non-parametrical method utilizes only the known e/h ratios and the electron calibration constants and does not require the determination of any parameters by a min...
Nível de dano econômico de Sitophilus zeamais (M.) em trigo armazenado
Santos,Anderson K.; Faroni,Lêda R. D'Antonino; Guedes,Raul N. C.; Santos,Jamilton P. dos; Rozazdo,Adriano F.Calcular o nível de dano econômico (NDE) para o principal inseto-praga Sitophilus zeamais (Motschulsky, 1895) do trigo armazenado, foi o objetivo deste trabalho. Para o cálculo do NDE relacionaram-se o grau de infestação e as perdas qualitativa e quantitativa dos grãos, depois de três meses de armazenamento. Utilizaram-se potes de vidro transparente de 2,5 L, com 1,5 kg de grãos de trigo tipo durum, da safra de...
Results from a new combined test of an electromagnetic liquid argon calorimeter...
Akhmadaliev, S.; Albiol, F.; Amaral, P.; Ambrosini, G.; Amorim, A.; Anderson, K.; Andrieux, M. L.; Aubert, B.; Augé, E.; Badaud, F.; Baisin, L.A new combined test of an electromagnetic liquid argon accordion calorimeter and a hadronic scintillating-tile calorimeter was carried out at the CERN SPS. These devices are prototypes of the barrel calorimeter of the future ATLAS experiment at the LHC. The energy resolution of pions in the energy range from 10 to 300 GeV at an incident angle [theta] of about 12° is well described by the expression , where E is...
Hadronic shower development in Iron-Scintillator Tile Calorimetry
Amaral, P.; Amorim, A.; Anderson, K.; Barreira, G.; Benetta, R.; Berglund, S.; Biscarat, C.; Blanchot, G.; Blucher, E.; Bogush, A.; Bohm, C.; Boldea, V.The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter presents a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behaviour is obtained. The underlying radial energy densities for the four depth...
Síndrome serotoninérgica associada ao uso de paroxetina: relato de caso
CAVALLAZZI,LUÍS OTÁVIO; GREZESIUK,ANDERSON K.Relatamos um caso de síndrome serotoninérgica pelo uso de inibidor da recaptação da serotonina, a paroxetina. Tal síndrome por esta droga, sem combinações, ainda não tinha sido descrita na literatura.
Evaluation of Fermi read-out of the Atlas Tilecal prototype
Ajaltouni, Z.; Albiol, F.; Alifanov, A.; Amaral, P.; Amelin, D.; Amorim, A.; Anderson, K.; Angelini, C.; Agnvall, S.; Antola, A.; Astesan, F.Prototypes of the FERMI system have been used to read out a prototype of the ATLAS hadron calorimeter in a beam test at the CERN SPS. The FERMI read-out system, using a compressor and a sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. ; http://www.sciencedirect.com/science/article/B6TJ...
Interlaboratory comparisons of petrography of liquefaction residues from three ...
Hower, J. C.; Anderson, K. B.; Mackay, G.; Pinheiro, H.; Flores, D.; Lemos de Sousa, M. J.Three Argonne Premium coal samples, the Beulah-Zap lignite (North Dakota), the high volatile A bituminous Stockton (West Virginia), and the low volatile Pocahontas No. 3 (Virginia), were ground to three initial sizes: -20 mesh, -100 mesh, and "micronized". The samples were each subjected to liquefaction at 673 K for 30 min at a 2:1 tetralin :coal ratio and in an H 2 atmosphere at 13.79 MPa (~ 2000 psi). Polishe...
