A comparison of the influence of barn-cured and field-cured alfalfa hay on milk production
… was conducted to compare the influence of barn-cured and field-cured alfalfa hay out from the same field on milk production and liveweight of dairy cows. Twelve Holstein cows were used in this trial. The double-reversal feeding method was followed. Grain was fed at the same rate to each group of …

Flue-cured tobacco: alternative management systems
The United States share of the exported flue-cured tobacco market has decreased over the last decade as other countries have increased production of improved quality tobacco. Such tobacco is available at a substantially lower price than U. S. tobacco and thus desirable for the manufacture of less …

Degradation and stabilisation of diisocyanate cured polybutadiene
Hydroxyl terminated polybutadiene (HTPB) has been used as a rocket propellant binder which is required to be stored for at least twenty years. It is found that the excellent stress-strain characteristics of this propellant can be totally lost, during this long storage, due to the deterioration of …

Strip-till flue-cured tobacco production in Virginia
Flue-cured tobacco (Nicotiana tabacum L.) is an intensively cultivated crop that typically receives four to eight primary tillage passes before being transplanted on a raised row-ridge. Strip-tillage, a conservation tillage system that only requires tilling a small strip before transplanting, has …

Studies of Low-Nicotine Flue-Cured Tobacco Production
Flue-cured tobacco (Nicotiana tabacum) has been managed to optimize the yield of high-quality cured leaf while maintaining nicotine levels within a relatively narrow range based on the Regional Minimum Standards Program. Among the 3,000 plus alkaloids found in tobacco, nicotine accounts for greater …

Self-healing of high temperature cured epoxy and composites
… have limited applications in low-temperature cured polymer matrices. Initially, self-healing epoxy adhesives were developed using a proven healing system - encapsulated dicyclopentadiene (DCPD) monomer and Grubbs’ first generation catalyst particles. Both quasi-static fracture and fatigue …

Quarterly import demand for North American flue-cured tobacco
… in the North American market share of flue-cured tobacco exports indicates that producers on this continent have entered into an era of competition from foreign flue-cured tobacco exporters. In order to understand this problem and obtain additional information on the factors influencing …

Prediction of Water Activity in Cured Meat using Microwave Spectroscopy
… techniques to determine quality parameters in cured meat. The first approach is online monitoring of weight loss in the meat curing process, which is a significant measurement for the meat industry because the weight loss is used as a method of tracking the curing process. Currently, weight …

Processing - Structure - Property Relationships in Catalyst Cured Epoxy Systems (Morphology)
… bulk density and morphology for catalyst cured epoxy systems based on diglycidyl ether of bisphenol A (DGEBA). The methods of thermally stimulated discharge (TSD) analysis, free oscillation torsion pendulum, differential scanning calorimetry (DSC), tensile mechanical test, and transmission …

Characterizing resistance in flue-cured tobacco to Globodera tabacum solanacearum
… to Globodera tabacum solanacearum in flue-cured tobacco was characterized in vitro, in the greenhouse, and field. The objectives of this study included evaluation of hatching of G. t. solanacearum as stimulated by root exudate, penetration and development of G. t. solanacearum on roots, and …

Responses of flue-cured tobacco to harvesting and curing variables
Two flue-cured tobacco varieties (Nicotiana tabacum L.) and eight harvesting and curing methods were simultaneously evaluated. Harvesting variables involved the removal of different leaf numbers on different schedules. Curing methods included single or separate barn conventional curing and a bulk …

Visible Light Cured Thiol-vinyl Hydrogels with Tunable Gelation and Degradation
Hydrogels prepared from photopolymerization have been widely used in many biomedical applications. Ultraviolet (200-400 nm) or visible (400-800 nm) light can interact with light-sensitive compounds called photoinitiators to form radical species that trigger photopolylmerization. Since UV light has …

Steam Cured Self-Consolidating Concrete and the Effects of Limestone Filler
… of self-consolidating concrete designed and cured for precast/prestressed applications. This study investigates the role of limestone filler on the hydration kinetics, mechanical properties (12 hours to 300 days), microstructural and durability performance (rapid chloride permeability, linear …

Efficacy of Herbicide Combination on Burley and Dark-Air Cured Tobacco
… of herbicide combination on burley and dark air-cured tobacco Nictotiana tabacum were tested in field research plots in the summer of 2000 at Western Kentucky University's Agricultural Research and Education Complex. The randomized complete block design contained six treatments replicated three …

Structure-property relationships of electron beam cured systems containing bis-GMA
… the acrylate end groups were more reactive in EB cured systems than analogous methacrylates probably due to their higher polymerization enthalpy and less steric hindrance. Phase separation, which would provide rubber toughening without depressing the high glass transition temperature, was not …

Influence of ethephon on growth and flowering of flue-cured tobacco
… acid) influences growth and flowering of flue-cured ‘NC 82’ tobacco; 2) examine the relationship between temperatures in the seedling environment and premature flowering and determine how time of plant bed cover removal affects premature flowering; and 3) quantify the ethylene released from …

Evaluating the potential of aerial remote sensing in flue-cured tobacco
Flue-cured tobacco (Nicotiana tabacum L.) is a high value-per-acre crop that is intensively managed to optimize the yield of high quality cured leaf. Aerial remote sensing, specifically unmanned aerial vehicles (UAVs), present flue-cured tobacco producers and researchers with a potential tool for …
