Selective Control o Egyptian Broomrape (Orobanche Aegyptiacapers.) by Glyphosate and its Amino Acid Status in Relation to Selected Hosts
… due to reduced crop alternatives. Few effective control measures exist for broomrapes. One of the most promising approaches is the use of low rates of glyphosate in hosts with tolerance to the herbicide. Recently, availability of glyphosate-resistant crops has provided an alternative in broomrape …

Design and Engineering of Protected Superconducting Qubits
… reported. Additionally, we propose enhanced mode-selective control of the soft 0−π qubit using these parallel-plate capacitors. Finally, we discuss the remaining challenges of the soft 0−π qubit and introduce alternative parameter regimes that can potentially improve Raman-based control and qubit …

Load Frequency Control for Electric Water Heater Using DBSCAN Algorithm in real-time
… This thesis develops and validates a novel control strategy for residential water heaters to provide demand-side frequency regulation while maintaining customer comfort. The approach employs Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm to dynamically group …

Analisi funzionale dei recettori per le neurotrofine p75NTR e Trka in neuroblastoma
… neurite outgrowth is concomitant with a selective enhancement of the AP-1 activity and the transcriptional activation of genes such as GAP-43 and p21(CIP/WAF), known to be involved in the differentiation process. Collectively, our results unveil a functional link between the specific …

Size and chemistry selective membranes from block polymer templates
… this dossier, we detail the efforts into the controlled radical polymerization of polyisoprene-<em>b</em>-polystyrene-<em>b</em>-poly(<em> N,N</em>-dimethylacrylamide) (PI-PS-PDMA) via. a facile reversible addition-fragmentation chain transfer (RAFT) mechanism. For this high molecular weight …

Physiological and Environmental Basis of Turfgrass and Weed Response to Mesotrione Formulations
… dioxygenase (HPPD). Although mesotrione controls many species of grass and broadleaf weeds, it is best know for selective control of perennial grasses like creeping bentgrass (Agrostis stolonifera L.). Field trials conducted at Virginia Tech and Blacksburg Country Club determined that …

Some physiological aspects of selective orchardgrass control in Kentucky bluegrass with bromacil
… (bromacil) for the selective removal of orchardgrass (Dactylis glomerata L.) from Kentucky bluegrass (Poa pratensis L.) turf and some physiological responses of the grasses to bromacil were evaluated in field studies. Bromacil reduced photosynthesis to a greater …

Development of New Organic Photoredox Catalysis Driven by Visible Light
… (PQ) promotes hydrogen atom transfer (HAT) to selectively generate acyl radicals from corresponding aldehydes without inducing crossover reactivity of thioesters. In situ formed acyl radicals then react with thiosulfonate S-esters to efficiently produce thioesters. The mild and efficient method …

Biophysics of Helices: Devices, Bacteria and Viruses
… design of microswimmers. First, the ability to selectively control large ensembles and second, the adaptivity to move through complex conduit geometries, such as the constrictions and curves of the tortuous tumour microvasculature. In this dissertation, a mechanics-based selective control …

Advancing Step-Growth Polymers: Novel Macromolecular Design and Electrostatic Interactions in Polyesters and Polyurethanes
… compared to a non-segmented copolyester control. Atomic force microscopy uncovered unique needle-like, interconnected, microphase separated surface morphologies, and small-angle X-ray scattering confirmed the presence of bulk microphase separation. This new synthetic strategy enabled …

Field and laboratory investigations on the efficacy, selectivity, and action of the herbicide clomazone
… is a recently introduced herbicide for the selective control of grass and broadleaf weeds in soybeans. Field studies were conducted in full-season no-till soybeans to determine the efficacy of clomazone as a preplant and preemergence herbicide. Clomazone applied preemergence provided large …

The control of yellow and purple nutsedge (Cyperus esculentus and rotundus) in turfgrass utilizing halosulfuron
Yellow and purple nutsedge are difficult to control worldwide. In turfgrass, the availability of herbicides that provide selective control of these weeds is limited. To address this problem, a sulfonylurea herbicide, halosulfuron, is being developed for the control of both yellow and purple …

Experimental and Theoretical Study of Resonance Raman Spectroscopy in Ground and Excited Electronic States
… powerful tool for the identification, study, and selective control of molecular processes. Raman scattering is particularly useful in observing the vibrational properties of molecules, and identifying compounds based on structure. While the experimental measurements provide structural information …

Influence of Annual Bluegrass on Putting Green Trueness and Control of Weedy Poa Species in Kentucky Bluegrass and Creeping Bentgrass Turf
… throughout the United States. Herbicides for selective control of these weeds in cool-season fairways are limited and ineffective. Methiozolin is a new isoxazoline herbicide that controls annual bluegrass on putting greens and shows promise for possible weed control in fairways. Kentucky …

A New Class of Antibiotic That Prevents Drug Tolerance, Persistence, and Resistance By Controlling Emergence of Phenotypes.
… of the ligand identified for each protein. This selective control of two proteins makes the correlation between the protein receptor to their controlled phenotypes. Inhibiting LecA results in reducing biofilm formation, eliminating small colony variants, and correlates with killing tolerant …
