Effect of Organic Amendments on Heavy Metal Distribution and Uptake in Vegetable Gardens in Senegal
(Virginia Tech, 2016-09-23)The major constraints to food production in West Africa are related to the lack of suitable lands. Consequently, farmers incorporate organic amendments and wastewater to improve their yields. Within some limits, such wastes ... -
The effects of various concentrations of phytase on broiler growth performance, phosphorus digestibility, tibia ash, and phosphorus utilization
(Virginia Tech, 2016-09-22)Two experiments were conducted to determine the effects of various phytase concentrations on broiler growth performance, carcass composition, phosphorus digestibility, tibia ash and phosphorus utilization. The first ... -
The Dietary Patterns, Behavioral/Health Perceptions, and Nutrition Knowledge of Smoking and Nonsmoking Foodservice Shiftworkers
(Virginia Polytechnic Institute and State University, 1987)The effects of shiftwork can be complex and nonuniform. This study was conducted to determine the dietary patterns, behavioral/health perceptions, and nutrition knowledge of smoking and nonsmoking foodservice shiftworkers.
Experimental Evaluation of the Rate of Rise Technique for Measuring Outgassing Rates in a Vacuum
(Virginia Polytechnic Institute, 1967)With an increase of interest in space flight and vacuum research, there has been a corresponding increase in the need for values of outgassing rates of many materials. In space flight the knowledge of the outgassing rates ...Gender and Pest Management in the Ecuadorian Andes
(Virginia Tech, 2011-03-23)This research was conducted to assess the intersection of gender and pesticide knowledge to identify gendered dynamics that may prove important to consider when implementing an Integrated Pest Management (IPM) program. Key ...Shade, Moisture, and Woody Vegetation in Stormwater Management Basins: Influence on Cattail (Typha spp.) Growth
(Virginia Tech, 2010-04-30)Stormwater management basins (SWMB) are used to mitigate urban runoff. The Virginia Department of Transportation relies on dry detention basins planted with mowed turfgrass. However, these basins often retain water; resulting ...Spatial Relationships Between Potential Bioavailable Organic Carbon and Sediment Grain Size at a Chlorinated Solvent-Contaminated Site
(Virginia Tech, 2011-02-03)Chlorinated ethenes are considered one of the most prevalent sources of groundwater contamination in developed countries. Natural attenuation of chlorinated ethenes is possible through the process of microbial reductive ...The Citizen-Soldier in the American Imagination: Traces of the Myths of World War II in the "Army Strong" Recruitment Campaign
(Virginia Tech, 2010-05-03)The myth of the citizen-soldier resonates strongly in the American imagination and helps (re)construct America the nation. The construction of this myth in the historical context of World War II is especially prominent in ...A Comparative Study of Cooling System Parameters in U.S. Thermoelectric Power Plants
(Virginia Tech, 2010-08-30)As the importance of water use in the power generation sector increases across the nation, the ability to obtain and analyze real power plant data is pivotal in understanding the water energy nexus. The Navajo Generating ...Characterization of Laminated Magnetoelectric Vector Magnetometers to Assess Feasibility for Multi-Axis Gradiometer Configurations.
(Virginia Tech, 2010-11-19)Wide arrays of applications exist for sensing systems capable of magnetic field detection. A broad range of sensors are already used in this capacity, but future sensors need to increase sensitivity while remaining ...The Absurd and Film: From the Existential Moment to Metaphysical Revolt
(Virginia Tech, 2010-04-30)In recent cinematic history, films have often expressed through the experiences of characters an 'existential moment' in which fundamental assumptions about life are questioned and potentially rendered meaningless. The ...Chuaria, Vendotaenia, and the taphonomy of the Carbonaceous Compression
(Virginia Tech, 2010-05-03)Carbonaceous Compressions are a widespread preservational style for fossils, yet their taphonomy remains poorly understood. Previous studies focusing on the taphonomy of carbonaceous compressions have primarily looked at ...Gender and Pest Management in Ghana: Implications for the Introduction of an IPM Program for Tomato
(Virginia Tech, 2012-04-20)The purpose of this research is to identify gender-based constraints and opportunities to the introduction of an Integrated Pest Management (IPM) program for tomato crops based on a case study of tomato farmers in the town ...Crystallization, Melting Behavior, Physical Properties, and Physical Aging of Ethylene/1-Octene Copolymers
(Virginia Tech, 2011-05-03)The time dependence of the physical properties of ethylene/1-octene (EO)-copolymers after primary crystallization is investigated by calorimetry, density, and creep measurements. The temporal evolution of the multiple ...INTRACELLULAR TRANSPORT IN CANCER TREATMENTS: CARBON NANOHORNS CONJUGATED TO QUANTUM DOTS AND CHEMOTHERAPEUTIC AGENTS
(Virginia Tech, 2012-04-26)Cancer therapies are often limited by bulk and cellular barriers to transport. Nanoparticle or chemotherapeutic compound intracellular transport has implications in understanding therapeutic effect and toxicity. The scope ...Evaluation of the Jet Test Method for determining the erosional properties of Cohesive Soils; A Numerical Approach
(Virginia Tech, 2012-05-02)Estimates of bank erosion typically require field measurements to determine the soil erodibility since soil characteristics are highly variable between sites, especially for cohesive soils. The submerged jet test device ...Response of Peripheral Blood Lymphocytes from RAO-affected Horses to b2-Agonist Stimulation
(Virginia Tech, 2011-05-03)Recurrent airway obstruction (RAO) affects middle-age horses, inducing bronchoconstriction and airway inflammation. β2-agonists like salbutamol are used as treatment, promoting airway smooth muscle (ASM) relaxation and ...Operationalizing Scale in Watershed-based Stormwater Management
(Virginia Tech, 2011-04-29)Watershed-based stormwater management (WSM) has been proposed as more effective for stormwater management than traditional methods of controlling stormwater, which are carried out based on jurisdictional lines at the ...A Bidirectional Pipeline for Semantic Interaction in Visual Analytics
(Virginia Tech, 2016-09-21)Semantic interaction in visual data analytics allows users to indirectly adjust model parameters by directly manipulating the output of the models. This is accomplished using an underlying bidirectional pipeline that first ...Crush Strength Analysis of Hollow Glass Microspheres
(Virginia Tech, 2016-09-21)Porous Wall Hollow Glass Microspheres (PWHGMs) were developed by the Savannah River National Laboratory. What makes these microspheres unique is the interconnected porosity spread throughout their wall allowing various ...
