We evaluated the efÞcacy of the systemic insecticides dinotefuran, emamectin benzoate, Þpronil, and imidacloprid for preventing attacks and brood production of southern pine engraver beetles (Coleoptera: Curculionidae: Scolytinae) and wood borers (Coleoptera: Cerambycidae) on standing, stressed trees and bolt sections of loblolly pine, Pinus taeda L., in eastern Texas. Emamectinbenzoate signiÞc...

For high current synchrotron SIS it is crucial to improve the multiturn injection efficiency. We study active emittance exchange due to a second order (skew quadrupole) difference resonance which is modified by the presence of space charge. We start from an analytical expression for the coherent tune shift of this resonance and compared it with computer simulation for the SIS synchrotron lattic...

A theory of dipole flow is developed to model flow induced by a vertical circulation well consisting of injection and extraction chambers in a single borehole. Included in the theory are an analytical description of the kinematic flow structure around a vertical circulation well and the drawdown in the well chambers. Using Stokes' stream function, simple criteria are derived to determine the re...

Despite of the technological importance developing AlGaN deep UV LEDs on Si, there are only a few reports about Si based epilayers. Herein, we show vertical with polarization enhanced p-AlGaN epilayer. The devices emit at 278 nm, uniform current injection. Compared to using standard epilayer, series resistance epilayer is reduced by factor 5. This work represents first report

7 Persistent scatterers synthetic aperture radar interferometry (PSI) analysis is viewed as a 8 promising monitoring technique for multiyear detection of ground surface displacements 9 during long term CO2 injection into deep aquifers (of the order of 25 to 50 years). 10 This technique was successfully utilized at the CO2 storage site of In-Salah (Algeria). 11 Nevertheless, this success may not...

We present a three-dimensional thermohydromechanical numerical study of the evolution and distribution of the stress tensor within the northwest part of The Geysers geothermal reservoir (in California), including a detailed study of the region around one injection well from 2003 to 2012. Initially, after imposing a normal faulting stress regime, we calculated local changes in the stress regime ...
