Corn response to long-term application of CuSO₄, ZnSO₄ and Cu-enriched pig manure
… The first field study consisted of continuing a longterm field experiment which was established in 1967 to evaluate corn response and changes in a Davidson clay loam soil to yearly additions of Cu and Zn sulfates. In 1983, the 17 annual additions of Cu and Zn resulted in cumulative totals of 280 …

Corn responses to high levels of copper application as copper rich pig manure
… three diverse Virginia soils indicated that the long-term application of Cu as either copper sulfate or Cu rich pig manure, even at high application rates (average application rate for 9 years was 108 metric tons of manure ha⁻¹ year⁻¹ or 32 kg Cu ha⁻¹ year⁻¹), had no adverse effects on corn …

Recursive Bayesian Filtering Through a Mixture of Gaussian and Discrete Particles
… filtering problems fall into two categories, deterministic and stochastic approaches. While the former is heavily used due to low computational demand, approximation error is tied to their initialization, which causes difficulty during long term application. The latter circumvents this but at …

Fostering Populations of Arbuscular Mycorrhizal Fungi Through Cover Crop Choices and Soil Management
… on yield. In the same trial, it was shown that long term application of nitrogen fertiliser influenced AM fungal community composition, but this observation was not made in a shorter validation experiment conducted at the field scale. In a sepa-rate trial, addition of a commercial AM fungal …

Phosphate Reactivity in Long-Term Manure Amended Soils in the Ridge and Valley of Virginia
… in ammonium oxalate. More recently, soils with a long-term history of manure application have exhibited properties that indicate calcium (Ca) may also be limiting P, especially in soils impacted by poultry manure. Accurate estimation of P loss potential is critical for justification of long-term …

Suitability of distributed mobile wireless networking for urban traffic congestion mitigation
… this first stage system are presented two more application scenarios according to increasing levels of penetration and increased reliability of the network. The medium-term application is the provision of mobile Internet access to allow consumer and business services. The long-term application …

Enhancing Mesenchymal Stem Cell Chondrogenesis for Cartilage Tissue Engineering
… with respect to functional growth. Transient application of TGF-β3 improved the compressive properties of MSC-laden constructs, but only when constructs were formed at a higher seeding density. Long-term dynamic compression initiated 3 days after MSC encapsulation impaired functional …

Long-term Impacts of Annual Cattle Manure and Fertilizer on Soil Quality Under Corn-Soybean Rotation in Eastern South Dakota
… soil quality; however, their impacts under long-term application in corn-soybean rotation need to be evaluated. Nutrient based recommended rates of manure applications on soils are important and also need to be monitored. This study, therefore, was conducted at two long-term sites to assess …

Environmental reviews and environmental management systems: Methodologies and organisational impacts
… environmental management strategies and the long term application of these techniques within each of these sectors. These findings are then drawn together in Chapter 5 to identify common methodological, organisational and political factors which affect the success of organisational …

Development and Characterization of highly flexible and conformable electronic devices for wearable applications
… beyond wearable devices to more-than-wearable applications. In this context, epidermal electronics is a closely related field that focuses on developing electronic devices that can be directly attached to the skin with a minimally invasive, comfortable, and possibly enabling long-term …

Strengths and limitations of bioretention sorbent amendments to simultaneously remove metals, PAHs, and nutrients from urban stormwater runoff
… parameters on sorbents performance. Then, a long-term vegetated column study was conducted to investigate the performance of three amendments (CCF, WTCR, and BFS) under intermittent runoff condition considering different runoff intensities and antecedent dry periods (ADP). The long-term …
