Early Season Population Dynamics and Residual Insecticide Effects on Bird Cherry-oat Aphid, Rhopalosiphum padi in Arkansas Winter Wheat
… through random sampling of whole plants and pan trapping methods to evaluate aphid immigration. The field plots were divided into four subplots treated with a systemic insecticide seed treatment (at the recommended rate of 0.148 liters of insecticide per 45 kilograms of seed or 5.0 fluid ounces …

A new apparatus for experiments with Caesium Bose-Einstein Condensates
… distribution of the atoms. Laser cooling and trapping methods are introduced, and the effects of each cooling stage on the gas are demonstrated. The final cooling stage, evaporative cooling, is presented by way of examining the gas after it has undergone each evaporation phase so we observe …

Botanical processes in urban derelict spaces
… bank investigation, field mapping and seed rain trapping methods. Interpretation of the data involved a range of approaches including vegetation classification and ordination, comparative analysis of plant functional attributes and the development of regression models incorporating landscape and …

Flight Activity, Oviposition Pit Distribution, and Emergence Densities of Monochamus titillator and M. carolinensis in the Ozark-St. Francis National Forest in Arkansas
… of Monochamus species may allow refinement of trapping methods, as well as better understanding of how Monochamus species interact among each other.</p>

Vertical activity, host preference, and population studies of adult Culicoides (Diptera: Ceratopogonidae)
… whether the host was a bird or a mammal. Three trapping methods (Goat-Baited Trap, Black Light Trap, and D-Vac) were employed simultaneously to investigate the seasonal and daily activity patterns of Culicoides and to determine the relative effectiveness of the three methods. The Black Light …

Unconventional structured semiconductors and their applications in optoelectronics and photovoltaics
… (1-5 μm thick) combined with effective light trapping methods. We have developed a new capillary-driven self-assembly process to generate three-dimensional (3D) Si structures in millimeter range from a 2D precursor. Based on these 3D Si structures, we have constructed spherical and cylindrical …

The community ecology of a riverine turtle assemblage in the Tennessee River Gorge
… To examine these hypotheses, a balanced trapping regime was carried out during May through August, from 2000 to 2006, in the Tennessee River Gorge. Trapping methods included baited traps (hoop nets and fyke nets) and unbaited traps (fyke nets, basking traps, hand capture, and trammel …

The silicon-vacancy centre in diamond for quantum information processing
… to atom-like quantum properties without complex trapping methods while displaying a rich physics due to interactions with their solid-state environment. Such properties have made them an advantageous building block for quantum information processing, in particular to construct a quantum network, …

Host plant associations and chemical ecology of Cerambycidae
… my dissertation research was to evaluate current trapping methods and potential ways of optimizing these methods. I compiled a comprehensive list of larval hosts for North American cerambycid species based on rearing records and larval gallery descriptions to gain a better understanding of …

The Ecological Effects of Cattle Grazing on Reptiles and Small Mammals in a San Joaquin Valley Grassland
… pairs of two grazed and two ungrazed sites. Live trapping methods appropriate to sampling reptiles (coverboards and pit fall traps) and small mammals (Sherman live traps) were used to determine species richness and abundance of these taxa. <em>Uta stansburiana</em> (side-blotched lizard) …

Mechanism of Action of Antipsychotics, Haloperidol and Olanzapine in vitro
… deoxyribose degradation assay and EPR spin trapping methods. HP was also found to quench singlet oxygen in a dose-dependent manner. HP was found to enhance the microsomal lipid peroxidation in a dose-dependent manner and at 10 µM it augmented the lipid peroxide accumulation by 100% whereas …

Improved estimates of risk of exposure to pathogens transmitted by mosquitoes
… of mosquito abundance are affected by the trapping methods used to capture them, and we considered the degree to which this factor needs to be taken in to account when analyzing mosquito abundance data. Further, we developed weather based weekly prediction models for the WNV mosquito …

Screen design for Borrelia burgdorferi lipoprotein secretion pathway components using periplasmic protein capture and suppressor mutations
… yielded no subsurface CspA. Second, two protein trapping methods were attempted. These were designed to stall the interaction between pathway components and lipoproteins inside of the periplasm. The introduction into the bacterial periplasm of the mammalian binding protein Calmodulin and surface …

Artificial Night Lighting and Anthropogenic Noise Alter Animal Activity, Body Condition, Species Richness, and Community Structure
… the two when both were present. We used standard trapping methods across a gradient of light, noise, and both combined while also accounting for variations in moonlight, vegetative structure, and weather. We found that an increased level of artificial night-lighting resulted in lower trap success …

Flame and fodder: how fire and grazing shape arthropod communities in the Okavango Delta
… richness, evenness and diversity varied between trapping methods and between groups studied, illustrating the varied responses of arthropod communities to disturbances. Ants and Collembola varied significantly between seasons, but not between disturbance types, while wasps and spiders differed …

Integrated pest management of the banana weevil, Cosmopolites sordidus (Germar), in South Africa
… determine the potential of semiochemical mass trapping, elucidate the efficacy of cultural and chemical control methods and establish economic thresholds for the banana weevil on Cavendish bananas in South Africa. Pest status of the insect is variable around the world, and may be influenced by …
