Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.

LFCM vitrification technology. Quarterly progress report, January-March 1986

This report is compiled by the Nuclear Waste Treatment Progrqam and the Hanford Waste Vitrification Program at Pacific Northwest Laboratory to document progress on liquid-fed ceramic melter (LFCM) vitrification technology. Progress in the following technical subject areas during the second quarter of FY 1986 is discussed: melting process chemistry and glass development, feed preparation and transfer systems, melter systems, canister filling and handling systems, off-gas systems, and process/product modeling and control

Um modelo matematico de quantificacao do efeito da disponibilidade hidrica em soja.

Utilizando resultados de experimento instalado com as cultivares de soja Parana, Bossier e Santa Rosa, plantadas em quatro epocas (10/10; 10/11; e 10/01) durante os anos-agricolas 1976/77 a 1983/84, foi derivado um modelo matematico que quantifica o efeito da oferta hidrica sobre a resposta da soja a epoca de plantio. O modelo indicou os periodos criticos de deficiencia hidrica, e explicou 52,1% 57,9% e 58,0% da variacao total observada nas cultivares Parana, Bossier e Sana Rosa, respectivamente. O modelo selecionou o subperiodo R1-R4, com o mais critico para deficiencia hidrica, no caso da cultivar Parana. No que se refere as cultivares Bossier e Santa Rosa, o modelo selecionou os subperiodos R1-R4 e R4-R6, como os mais criticos para deficiencia hidrica.Made available in DSpace on 2011-04-09T12:07:03Z (GMT).
