Development and evaluation of shallow injection of slurry into ley [PDF]

, 2004
Shallow injection of slurry on grassland can reduce ammonia emissions compared to surface spreading and increase plant nitrogen utilisation. Other advantages include enhanced silage quality and lower odour.

Nitrous oxide emissions from multiple combined applications of fertiliser and cattle slurry to grassland

, 2008
Fertiliser and manure application are important sources of nitrous oxide (N2O) emissions from agricultural soils. The current default IPCC emission factor of 1.0% is independent of the type of fertiliser and manure, and application time, method and rate.

Mitigating Ammonia Emissions from Liquid Manure Using a Commercially Available Additive Under Real-Scale Farm Conditions

Atmosphere
Ammonia (NH3) is a major anthropogenic pollutant originating from agricultural activity, particularly livestock operations. NH3 emissions from livestock slurry storage pose risks to environmental quality and human health.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Incidental phosphorus and nitrogen loss from grassland plots receiving chemically amended dairy cattle slurry

, 2012
peer-reviewedChemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. This study examined P

Pressure drop of flowing ice slurries in industrial heat exchangers [PDF]

, 2009
Experiments were conducted to determine the characteristics of ice flows through industrial heat exchangers (a Tetra Plex (R) C6-SR and a Tetra Spiraflo (R) MTC70/W-3).

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Assessing Nitrogen Use Efficiency and Nitrogen Loss in a Forage-Based System Using a Modeling Approach

Agronomy, 2016
In intensive agriculture, N supply often exceeds crop requirements, even in nitrate vulnerable zones (NVZ). In farmland, the N surplus gives rise to NO3− leaching and consequent groundwater pollution.

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Assessing the balance between greenhouse gases and ammonia emissions from Irish pastures amended with cattle slurry [PDF]

, 2012
Agriculture in Ireland is the main source of ammonia (NH3) and contributes 30% of greenhouse gas emissions (GHG), with the majority of these emissions associated with livestock production.
