The present study investigates a Multi-Objective Transportation Problem within a fuzzy environment. The cost of transportation, supply, and demand data are assumed to be inaccurate due to market variations. As a result, the parameters are imprecise or fuzzy data. We offer a multi-objective, balanced transportation problem during this work, where all the parameters are fuzzy numbers. Following a mathematical formulation, fuzzy arithmetic will be used to divide the Fuzzy MOTP into three levels MOTP (lower, medium, upper). After reducing the problem to a crisp MOTP and applying a harmonic mean to each objective function, a suggested solution procedure is presented. Determining the optimal solutions for the FMOTP under unknown situations is, thus, the most important objective of this research.

Mine tailing deposits pose a global problem, as they may contain metal contaminants in various geochemical forms and are likely to be leached from the surface into the underlying groundwater, which can result in health and/or environmental risks. Unfortunately, little is currently known regarding the water flow and mass balance related to leaching in the vadose zone as these factors are still difficult to measure at the field scale. A pilot-scale experiment was run in a 1 m instrumented column for 6 months to address this issue.

The construction of engineering projects in the Chinese Loess Plateau has resulted in large areas of exposed slopes, increasing the risk of soil erosion. Restoring the slope ecosystem is an effective means to reduce soil erosion, prevent soil and water loss, and maintain slope stability. Ecological slope protection using bio-gum solidified fiber-reinforced loess (GFSL) has been proven to achieve good vegetation restoration effects, but there remains a problem of low vegetation coverage in the early stage of protection.

Schizophrenia (SZ) is a complex, chronic mental disorder characterized by positive symptoms (such as delusions and hallucinations), negative symptoms (including anhedonia, alogia, avolition, and social withdrawal), and cognitive deficits (affecting attention, processing speed, verbal and visuospatial learning, problem-solving, working memory, and mental flexibility). Extensive animal and clinical studies have emphasized the NMDAR hypofunction hypothesis of SZ. Glycine plays a crucial role as an agonist of NMDAR, enhancing the receptor's affinity for glutamate and supporting normal synaptic function and plasticity, that is, signal transmission between neurons.

The ability of nanofluids to improve heat transmission in thermal systems is well established. This work investigates the three-dimensional theoretical behavior of Darcy-Forchheimer nanofluids in tilted magnetohydrodynamics. In this study, the Soret effect, micro-motile organisms, thermophoresis, and heat radiation are also considered.

Droplet manipulation on functional surfaces is an urgent problem to be solved. Fast and precise droplet manipulation plays an important role in many applications, such as microreactors and microfluidics. Although numerous techniques have been developed to manipulate droplets by injecting external stimuli, it remains a challenge to achieve high-precision, high-sensitivity, and fast droplet manipulation on smart, slippery response surfaces.
