Article Abstract
Due to the worldwide water supply crisis, sustainable strategies are required for a better use of this resource. The use of magnetic water has been shown to have potential for improving irrigation efficacy. However, a lack of modelling methods that correspond to the experimental results and minimize error is observed. This study aimed to estimate the replacement rates of magnetic water provided by irrigation for lettuce production using a mathematical model based on fuzzy logic and to compare multiple polynomial regression analysis and the fuzzy model. A greenhouse study was conducted with lettuce using two types of water, magnetic water (MW) and conventional water (CW), and five irrigation levels (25, 50, 75, 100 and 125%) of crop evapotranspiration. Plant samples for biometric lettuce were taken at 14, 21, 28 and 35 days after transplanting. The data were analyzed via multiple polynomial regression and fuzzy mathematical modeling, followed by an inference of the models and a comparison between the methods. The highest biometric values for lettuce were observed when irrigated with MW during the different phenological stage evaluated. The fuzzy model provided a more exact adjustment when compared to the multiple polynomial regressions.

Bismuth ferrite (BiFeO), a perovskite oxide with both ferroelectric and antiferromagnetic properties, has emerged as a promising material for environmental cleanup due to its piezo-photocatalytic activity. The material's ability to degrade organic pollutants, such as azo dyes, under both light irradiation and mechanical stress (ultrasonic waves) offers a dual-action mechanism for efficient wastewater treatment. In this work, we explore the synthesis of BiFeO nanoparticles a simple sol-gel method, followed by characterization of their structural, magnetic, and photocatalytic properties.

Most individuals with moderate-to-severe diffuse axonal injury (DAI) have impaired verbal fluency (VF) capacity. Still, the relationship between brain and VF recovery post-DAI has remained mostly unknown. The aim was to assess brain changes in 13 cortical thickness regions of interest (ROIs), fractional anisotropy (FA), and free water (FW) in three language-related tracts; the VF performance at 6 and 12 months after the DAI; and whether brain changes from 3 to 6 months predict VF performance from 6- to 12-month post-DAI.

Water-ion interactions govern the physicochemical properties of aqueous solutions, impacting the structure of the hydrogen bonding network and ion diffusivities. To elucidate these effects under alkaline conditions relevant to diverse application spaces, we examined NaOD-DO solutions using two-dimensional infrared spectroscopy (2D-IR), small-angle X-ray scattering (SAXS), and nuclear magnetic resonance spectroscopy (NMR). Vibrational energy transfer between the donor anion SeCN, used as a 2D-IR probe, and the acceptor anion OD was used to track the average separation distance of ions in the DO solutions, while SAXS and NMR experiments measured the structure of the bulk DO solvent.

Synthesis, characterization, and electrocatalytic water oxidation studies of the cubane-type complexes [(μ-)CoCl(MeOH)] (1) and [(μ-)CoCl(MeOH)] (2) are herein reported. Cubanes 1 and 2 were obtained in high yields under mild conditions by self-assembly of the ligands = 1--2-benzimidazolylmethanol and = 1-methyl-2-benzimidazolylmethanol with CoCl·6HO in basic methanolic solution. Both compounds feature a cubane-type structure in which the central {CoO} units are built by four Co centers coordinated by alkoxide-bridged oxygen and nitrogen atoms from the deprotonated ligands and stabilized by MeOH molecules and chloride ions.
