Developing remote sensing approaches for integrated pest and pollinator management in turfgrass
… courses are currently using remote sensing and light reflectance to detect non-insect pests in turfgrass. This thesis aims to develop remote sensing and light reflectance methods to aid in a turfgrass IPPM plan, to document the phenology of ABW weevil (Listronotus maculicollis Kirby, Coleoptera: …

Grain hardness and slow dry matter disappearance rate in barley
… for SKCS hardness, milling energy, endosperm light reflectance, feed particle size, protein and beta-glucan. Hardness measurements ranked genotypes similarly across environments. Feed particle size was correlated with milling energy but not other hardness measurements. Hardness measurements …

Expanding the Application of Spectral Reflectance Measurement in Turfgrass Systems
Light reflectance from plants can be used as a non-invasive predictor of health and yield for many cropping systems, and has been investigated to a lesser extent with managed turfgrass systems. The frequent agronomic inputs associated with maintaining golf course grasses allow for exceptional stand …

A critical comparison of human face rendering techniques
Human skin exhibits complex light reflectance properties that make it difficult to render realistically. In recent years, many techniques have been introduced to render skin, with varying degrees of complexity and realism. In this thesis, I will implement several of these techniques, and use them …

Cloning and Characterization of the dominant Inhibitor of Wax 1 (Iw1) gene in polyploid wheat
… to determine the effects of non-glaucousness on light reflectance and transmission as well as on water-use efficiency (WUE). Finally, the composition of surface waxes in glaucous and non-glaucous NILs was elucidated using a combination of electron microscopy and biochemical methods. Here, we have …

Prothonotary Warbler (Protonotaria citrea) Plumage as an Indicator for Infection: the Relationship between Haemosporidia Infection and Breast Feather Reflectance in a Neotropical Migrant Passerine
… and status. This study describes breast feather reflectance of adult Prothonotary Warblers (Protonotaria citrea) (n=169), insectivorous Neotropical migrant passerines, throughout the Ultraviolet (UV) and human visible light spectra and examines the relationship between Haemosporidia (pathogen …

Tikslinis fotovoltinių silicio prietaisų savybių keitimas, panaudojant gilų paviršiaus tekstūrinimą ir dvimatės medžiagos dangas /
… This allowed for a predictable variation of the light reflection from the semiconductor surface. The thesis also presented a method for forming large-area black silicon using two-step metal-assisted chemical etching. The dependencies of the light reflectance on technological parameters such as …

The effects of common household cleaning agents and aging on the removal of quantitatively applied food stains from rayon, nylon, and olefin pile upholstery fabrics
… arm. Soil removal was evaluated by measuring light reflectance and color values on a Hunter Color-Difference Meter®. A consumer panel rated the specimens according to AATCC Stain Release Replicas, and stated whether or not each specimen was acceptable for use in their homes. Statistical …

Novel Optical Endoscopes for Early Cancer Diagnosis and Therapy
… place. Though visible and near infrared (NIR) light undergo a wide range of complex interactions in tissue — interactions which can be harnessed to yield useful information about the underlying pathology — optical imaging has yet to be fully utilised in clinic, with many existing techniques …

Introgression of genes from rape to wild turnip
… was nearly twice that for bee pollination. Light reflectance patterns under UV light revealed a marked difference between wild turnip and rape flowers compared to near identical appearance under visible light. The data indicates that bees are able to distinguish between rape and wild turnip …

Precision Nutrition Tools to Support Extensive Forage-Based Livestock Systems
… with a spectral sensor programmed to measure light reflectance at 18 wavelengths before bench chemistry analysis for each sample. The data collected were split into three parts and used in random forest regressions. We found that the resulting root mean square prediction errors (RMSPE) for …

Design of bio-inspired texturing treatments, via high power ultra-short pulse lasers, of ferritic stainless steel surfaces that inhibit the formation of bacterial biofouling on tools for hospital use and in the food industry
… of the nanostructured samples was consistently slightly higher than that of the untextured ones, maintaining a certain linearity concerning the SDAE of each treatment. Additionally, both qualitative and quantitative analyses of surface bright were conducted post-laser treatment, as this is an …
