Abstract:
... Continuous conducting lines of width 5–20 μm have been printed with a Ag nanoparticle ink using drop-on-demand (DOD) electrohydrodynamic (EHD) inkjet printing on Si and PDMS substrates, with advancing contact angles of 11° and 35°, respectively, and a zero receding contact angle. It is only possible to achieve stable parallel sided lines within a limited range of drop spacings, and this limiting r ...

Abstract:
... Microplastic (MP) contamination has been reported to be higher in terrestrial compared to aquatic environments. This is probably due to the fact that plastic items are mostly produced and used in terrestrial environments and have a longer residence time. However, there are several links between the terrestrial and aquatic environments. We analyzed drainage water samples from agricultural soils in ...

Abstract:
... Idealized numerical modeling of thermally driven baroclinic exchange is performed to understand how cross‐shore flow is modulated by steady alongshore currents and associated shear‐generated turbulence. In general, we find that shear‐driven vertical mixing reduces the temperature gradients responsible for establishing the baroclinic flow, such that cross‐shore thermal exchange diminishes with alon ...

Abstract:
... The selection of suitable drainage materials is crucial for the efficient operation of subsurface drainage systems. Previous studies on drainage material selection have focused on anti‐clogging characteristics, and less attention has been given to their effects on the process of soil salt leaching, which is an important consideration in arid and semi‐arid areas. To investigate the influence of sub ...

Abstract:
... A set of cloud-permitting-scale numerical simulations during January–February 2018 is used to examine the diurnal cycle (DC) of precipitation and near-surface variables (e.g., 2 m temperature, 10 m wind and convergence) over the Indo-Pacific Maritime Continent under the impacts of shore-orthogonal ambient winds (SOAWs). It is found that the DC of these variables and their variabilities of daily ma ...

Abstract:
... High indoor temperatures in traditional finisher pig buildings may lead to deteriorating production results, increased pen fouling and increased respiration rate and rectal temperature. Floor cooling may improve the thermal conditions for pigs on solid floors during warm periods, and therefore the objective was to investigate whether floor cooling could lower the respiration rate (RR), increase th ...

Abstract:
... The negative impact of agriculture on the quality of local water streams is widely recognized. Fertilizer residues not taken up by the crops leach into the drainage water and enter the surface water, resulting in eutrophication. Despite various initiatives to prevent this leaching by optimizing fertilizer schemes, the desired effect was not achieved, and the focus has shifted to denitrifying end-o ...

Abstract:
... Biopores and cracks in soils act as fast transport pathways for water and solute, potentially leading to pesticide leaching shortly after application. The biopore module in the agrohydrological model Daisy was developed to simulate preferential water flow directly to drainpipes, in drain‐connecting biopores, and to deeper soil layers, in matrix‐terminating biopores. We tested the biopore module in ...

Abstract:
... Tailings ponds Slovinky and Markušovce (Slovakia) belong to the group of high-risk areas threatening human health and the environment due to the high concentrations of potentially toxic elements. The aim of this study was to identify iron bacteria living in these extreme environments and to assess the impact of selected physicochemical parameters of drainage water, flowing from tailings ponds, on ...

Abstract:
... The environmental changes in the wetlands are one of the major problems facing us in recent decades. Lately, many fluctuations have been observed in Wadi El-Rayan lakes. The geo-spatial analysis plays a great role in detecting the changes in Wadi El-Rayan lakes. The aim of the current study is to enrich the knowledge about Wadi El-Rayan Depression and to identify the changes in its lakes (Upper La ...

Abstract:
... Weathering of mine waste rock can result in high concentrations of zinc (Zn) and cadmium (Cd) in surface and ground water. Design and implementation of mitigation measures requires an understanding of the mineralogical occurrence of Zn and Cd within the waste rock as well as the subsequent weathering and leaching processes. Recent geochemical studies have focused on the characterization of seleniu ...

Abstract:
... Measurements of the tracers, ¹²⁹I, CFC‐11, and SF₆ on water samples collected in the Arctic Ocean in 2015 have been used to calculate mean ages, Γ and mixing, Δ parameters using transit time distributions (TTDs) to constrain water circulation and mixing time scales. Values of Γ and Δ determined separately using the two tracer pairs, SF₆‐CFC‐11, and ¹²⁹I‐CFC‐11 are in good agreement for gas solubil ...

Abstract:
... Changing temperatures and precipitation patterns from climate change are a major risk to crop yields. Producers have technology options for mitigating this risk with one such technology termed drainage water recycling (DWR). DWR involves diverting subsurface drainage water to ponds where it is stored for later irrigation. Crop insurance may interfere with DWR adoption by providing producers with a ...

... In order to obtain smaller diameter melt-blown fiber, we improved the air slot of the melt-blown die in this research and designed the new melt-blown die with the gradually shrinking air slot and arc nose head. Using the numerical simulation method, we analyzed that the new die and the common die affect the velocity field, temperature field, air pressure field, and turbulence strength on the cente ...

Abstract:
... Mitigation measures are needed for reducing chronic dissolved phosphorus (P) losses from agricultural soils with a legacy of excessive P inputs to surface waters. Since pipe drains are an important pathway for P transport from agricultural soils to surface waters in flat areas, removing P from drainage water can be an effective measure. During a 4.5 year-field experiment, we tested the performance ...

Abstract:
... One of the common irrigation systems in the paddy fields is field-to-field irrigation. The management of these irrigation systems is difficult and essential because of the water scarcity. Estimating the parameters affecting the water balance in paddy fields is necessary by considering the irrigation requirements of downstream fields. The objective of this study is to develop a computational model ...
... The purpose of this study is to solve the problem of industrial waste storage. Waste from the production of mineral fertilizers is considered in this study (as an example—phosphogypsum LLC «Industrial group «Phosphorit»). Waste storages on a landfill have a significant negative impact on the environment. This fact has been confirmed by studies of wastewater from the dump (drainage water). Phosphog ...

Abstract:
... Agricultural drainage water quality changes over time until it reaches a balance. In areas with shallow and saline groundwater, it might take several years to reach a balance. In such cases, knowledge of the quantity and quality of drainage water is necessary to manage it. The drainage water generated must then be managed for reuse purposes where it is of suitable quality and is finally discharged ...

Abstract:
... Stakeholders for nutrient‐impaired watersheds have long discussed the causes and consequences of nutrient surpluses associated with intensive livestock production. Nonetheless, nutrient surpluses relative to crop requirement, particularly with phosphorus (P), persist and continue to contribute to water quality impairment. Nutrient life‐cycle analysis shows that mineral P, from soil minerals or min ...
