Abstract:
... Given the growth in consumers' environmental awareness, firms are increasingly concerned with used product reuse and remanufacturing. In this paper, we investigate two recycling cooperation modes: recycling alliance mode and cost sharing mode. We develop an analytical approach for determining whether and how the manufacturer and retailer in a closed-loop supply chain (CLSC) should enter a recyclin ...

Abstract:
... Solid-state nanopore has the ability to detect proteins at a single-molecule level with its high sensitivity, high-throughput, and low cost. Improvements in fabrication, functionalization, and characterization of solid-state nanopores keep evolving. Various analytical methods targeted towards diagnostic applications using nanopore-based devices are appearing. This review article provides an overvi ...

Abstract:
... Recent research related to the evolution of different types of green water events, generated in wave flume experiments, has shown that some events, such as plunging-dam-break (PDB) and hammer-fist (HF) types, can present multiple-valued water surface elevations during formation at the bow of the structure. However, the applicability of analytical models to capture the evolution (i.e., the spatio-t ...

Abstract:
... When analyzing agriculture’s total factor productivity, traditional measurement approaches do not take into account the inefficiency value. The production functions are assumed to be analyzed on basis of the random boundaries, which makes the analysis results inaccurate and unreliable. As a result, this paper proposes an analytical approach for agricultural total factor productivity based on the s ...

Abstract:
... Soil nitrogen (N) is controlled by several environmental factors. However, it is unclear how these factors and their interactions affect soil N fractions (SNFs) because of the lack of systematic N extraction methods. The Harbin–Dali belt, a transect more than 3,300 km long across China covering various climates, topographies, soil parent materials and vegetation types, was taken as the study area, ...

Abstract:
... Land consolidation is an instrument that readjusts land parcel shapes and reallocates land rights in order to minimize farmland fragmentation, optimize agricultural output, and generate optimal living and working conditions in rural areas. The optimization and reallocation algorithms typically rely on monetarized values of land parcels, soil quality, and compensation amounts. Yet, land management ...

Abstract:
... A collaborative trial (an interlaboratory study) is reputed to be the most reliable way of validating an analytical procedure applied to a defined class of test material. The most important outcome of a trial is the collection of reproducibility standard deviations estimated at various mass fractions of the analyte. These standard deviations are good estimates of standard uncertainties to be expec ...

Abstract:
... The application of high-temperature superconducting (HTS) equipment faces challenges that thick current leads connecting superconducting devices with external power sources will generate huge thermal load loss and the difficulty in persistent current operation for a long period. In this work, we have proposed the mechanism of a novel mechanically operated HTS energy converter based on the electrom ...

Abstract:
... Methylmercury (MeHg), a potent neurotoxin, can be formed, migrated and transformed in environmental compartments, accompanying with unique mass-dependent and mass-independent fractionation of mercury (Hg). These Hg isotope fractionation signals have great potential to probe the transformation and transport of MeHg in aquatic environments. However, the majority of studies to date have focused on to ...

Abstract:
... The objective of the current research is to develop a novel analytical approach for the performance evaluation and optimization of a run-of-river hydropower facility. Two types of turbines, Kaplan and Francis are considered and the analysis is validated on the basis of a new hydrological model through adopting a case study approach. In the second step of the study, a sensitivity analysis was condu ...

Abstract:
... ²³⁶U is an anthropogenic radionuclide that is produced from nuclear reactions of ²³⁵U(n, γ) and ²³⁸U(n, 3n). It has gained extensive attention in the field of environment, geology, nuclear emergency, and nuclear forensics. Due to the unique physical and chemical character and the distinct fingerprint character from different sources, ²³⁶U has been successfully applied in the environmental tracer, ...

Abstract:
... The hydrological conditions near the soil surface influence the soil erosion process, as determined by the soil erodibility and critical shear stress. The soil erodibility and critical shear stress of saturated purple soil slopes were computed and compared with those of unsaturated purple soil slopes. The detachment capacities computed through the numerical method (NM), modified numerical method ( ...

Abstract:
... Empirical wind-retrieval algorithms for synthetic aperture radar (SAR), such as the geophysical model function (GMF) CMOD5N in the C-Band, are currently well developed. The retrieval accuracy of GMFs, however, is lower in the presence of marine phenomena such as oceanic fronts and mesoscale eddies, making SAR wind retrieval challenging under these conditions. In this study, we proposed a scheme fo ...

Abstract:
... Tobacco and tobacco smoke contain a complex mixture of over 9500 chemical compounds, many of which have been recognized as hazardous to human health by regulatory agencies. In 2012, the U.S. Food and Drug Administration established a list of harmful and potentially harmful constituents in unburned tobacco and tobacco smoke, 79 of which are considered as carcinogens. Over the past 10 years, with ad ...

Abstract:
... Microplastics are a subject of growing interest as they are a potential threat for living organisms. Textile microfibers (MFs) are an important microplastics sub-group that have been reported as a major source of microplastics release into the environment. This pollution occurs mainly during the washing of synthetic garments. However, standardized methods to quantify and characterize these MFs are ...
