A new ruthenium complex, [RuBrCl(C28H32N2)], has been synthesized and characterized by elemental analysis, 1H NMR, 13C NMR, IR-spectroscopy and a single-crystal X-ray diffraction study. The Ru atom in this complex is best described as having a considerably distorted octa-hedral coordination environment with the arene occupying three coordination sites. Two further coordination sites are occupied by chloride and bromide ligands, while the sixth site is occupied by the carbene. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C6H4C(CH3)3 arene by a CH2 bridge. This leads to a system with very little apparent strain. …

Feature Preserving Continuous Level-Of-Detail For Terrain Rendering, Lucas Jay Shinkovich Dec 2008

Feature Preserving Continuous Level-Of-Detail For Terrain Rendering, Lucas Jay Shinkovich

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the vast processing power of modern GPUs, rendering terrain geometry at sufficient frame rates is still a very difficult task. This is mainly due to the large terrain data that must be managed, displayed and modified at high frame rates. While traditional level-of-detail algorithms for terrain utilize most of the CPU and a fraction of the GPU, our algorithm exploits the parallel processing capabilities of the GPU. We represent the terrain geometry as a set of geometry images which allows us to apply image processing techniques to preserve terrain features during level-of-detail transitions and to render terrain that has …

Side-Effects Of Pesticides On The Life Cycle Of The Mite Pathogenic Fungus Neozygites Floridana, V. W. Wekesa, M. Knapp, I. Delalibera

All Peer-Reviewed Publications

The tomato red spider mite, Tetranychus evansi Baker and Pritchard, is an invasive species in Africa causing considerable damage to Solanaceous crops. The fungal pathogen Neozygites floridana Weiser and Muma from Brazil has been considered a potential candidate for introduction into Africa for the control of T. evansi. To be incorporated in the tomato production system, N. floridana has to be compatible with the pesticides used for the control of other pests and diseases. Pesticides used in tomatoes that might affect the fungus were therefore studied by the use of different methods. Two insecticides (Lambda-cyhalothrin and Methomyl), two acaricides (Propargite …

Empirical Two-Point Α-Mixing Model For Calibrating The Ech2o Ec-5 Soil Moisture Sensor In Sands, Toshihiro Sakaki, Anuchit Limsuwat, Kathleen M. Smits, Tissa H. Illangasekare

Civil Engineering Faculty Publications - Archive

Recently improved ECH2O soil moisture sensors have received significant attention in many field and laboratory applications. Focusing on the EC-5 sensor, a simple and robust calibration method is proposed. The sensor-to-sensor variability in the readings (analog-to-digital converter (ADC) counts) among 30 EC-5 sensors was relatively small but not negligible. A large number of ADC counts were taken under various volumetric water contents (?) using four test sands. The proposed two-point a-mixing model, as well as linear and quadratic models, was fitted to the ADC – ? data. Unlike for conventional TDR measurements, the effect of sensor characteristics is lumped into …

Regulation Of Oviposition In Anopheles Gambiae S.S.: Role Of Inter- And Intra-Specific Signals, Leunita A. Sumba, C. Brandon Ogbunugafor, Arop L. Deng, Ahmed Hassanali

All Peer-Reviewed Publications

Females of Anopheles gambiae Giles normally oviposit in a large number of fresh, small, sunlit, and spatially spread temporary pools. Such pools are associated with lower levels of predation compared to large, longer-lasting habitats. We compared oviposition levels on preferred (water collected from natural anopheline larval habitats) and non-preferred (distilled water) aqueous substrates by gravid females that contained different densities of conspecific eggs or early and late instar larvae. The presence of conspecific larvae, but not eggs, had a positive or negative effect on the ovipositional responses of gravid An. gambiae females, depending on the quality (preferred or non-preferred by …

On Representations Of Quantum Groups Uq(Fm(K,H)), Xin Tang, Yunge Xu Oct 2008

On Representations Of Quantum Groups Uq(Fm(K,H)), Xin Tang, Yunge Xu

College of Health, Science, and Technology

We construct families of irreducible representations for a class of quantum groups Uq(fm(K,H). First, we realize these quantum groups as hyperbolic algebras. Such a realization yields natural families of irreducible weight representations for Uq(fm(K,H)). Second, we study the relationship between Uq(fm(K,H)) and Uq(fm(K)). As a result, any finite-dimensional weight representation of Uq(fm(K,H)) is proved to be completely reducible. Finally, we study the Whittaker model for the center of U q(fm(K,H)), and a classification of all irreducible Whittaker representations of Uq(fm(K,H)) is obtained. © 2008 Australian Mathematical Society.
