[EN] The dataset contains information on citrus fruit prices and varieties across different provinces in the Comunitat Valenciana, Spain, over multiple seasons (2015-2016 to 2023-2024 seasons). It includes various statistical indicators derived from weekly price observations. The data aims to support agricultural market analysis, price forecasting, and clustering methodology research., Authors acknowledge the support of “Ayuda a Primeros Proyectos de Investigación (PAID-06-22), Vicerrectorado de Investigación de la Universitat Politècnica de València (UPV)”.

The Bezold effect, known by the influence of the shape and size of surrounding objects on the color appearance of a stimulus, has been studied by numerous authors. Situations have been studied in which the color stimulus is superimposed on an achromatic grating consisting of black and white lines arranged alternately with different spatial frequencies. The aim of the work is to determine whether the orientation of the grating lines (horizontal or vertical) induces a significantly different color appearance variation for different grating frequencies. A set of observers with normal color vision evaluated the variations in the color appearance of three light stimuli when superimposed on the same grating arranged horizontally and vertically, according to a procedure described by the authors in a previously published paper. The results show that the samples observed on the horizontal pattern present a Bezold effect significantly higher than those obtained when the samples are observed on the vertical pattern.

This dataset includes the raw data collected from two Open Access megapublisher websites (mdpi.com and frontiersin.org) across several SEO tools (Ahrefs, Semrush, SERPstats, Ubersuggest, Sistrix). From each domain name, SEO-level metrics (e.g., organic keywords, global traffic, traffic by country) were collected and structured.

[EN] This dataset includes bibliographic metadata on publications related to university rankings, used as a baseline for a literature review on the topic. Specifically, 1730 publications collected from Scopus were categorized according to types of university rankings studies, and three thesauri were used in VOSviewer for data normalization.

[EN] The overall objective of the NEW4ALMOND project is to improve the health status and productivity of almond, through the development of techniques and procedures that allow reducing the impact of the most important diseases of the crop and thus contribute to its management from an economic and environmental point of view. The NEW4ALMOND_SP3_Diaporthe_amygdali_Population_Genetics dataset includes part of the data obtained in the activities of Subproject 3 developed at the UPV related with improving the knowledge about the population genetics of Diaporthe amygdali.

[EN] The efficiency of Orange G (OG) azo dye degradation using an electrochemical method under potentiostatic conditions has been comparatively studied in two electrolytic cells (divided and undivided cells) in the presence or absence of chloride ions with Pt-modified textile electrodes. The morphology of the carbon-based electrodes with nanoparticles of platinum electrochemically dispersed on their surface was analyzed using field emission scanning electron microscopy (FESEM) and EDX analysis. The FESEM analyses confirmed that the textile surface was coated by Pt nanoparticles. According to the experimental results obtained, when the same solutions are comparatively treated with the two cells, the undivided cell always gives a quicker decolorization than the divided cell – and the decrease in total organic carbon (TOC), chemical oxygen demand (COD), and total nitrogen (TN) confirms this result. The degree of OG removal was monitored by spectroscopic methods and high-performance liquid chromatography (HPLC). The results indicate that that full best dye removal is obtained at a loaded charge of around 0.17 Ah L−1 which is associated with an electrical energy per order (EEO) of 0.189 kW h m−3 order−1. Based on the results obtained, the electrochemical process with TCRGO-Pt electrodes could be useful as a pretreatment technique or treatment for decolorizing wastewaters containing dyes., The authors wish to thank the Spanish Agencia Estatal de Investigación (AEI) and European Union (FEDER funds) for the financial support (contract MAT2016-77742-C2-1-P) and Chemviron Carbon who kindly donated the FlexzorbTM FM10 activated carbon fabrics.

[EN]This dataset contains anonymised responses to a national survey conducted in Spain between June 2021 and June 2022. The survey explores menstrual health, education, access to menstrual products, perceived stigma, and the impact of menstruation on daily life. It includes responses from a diverse population and aims to contribute to research on menstrual equity and social perceptions of menstruation in the Spanish context.

[EN] Pectin, a multifunctional polysaccharide with food, pharmaceutical and biomedical applications, can be sustainably extracted from Theobroma cacao and Coffea arabica pod husk waste. This study optimized an eco-friendly, ascorbic-acid-assisted acid extraction to maximize galacturonic acid (GalA) content, achieving optimal conditions for cocoa (R= 0.02 g/mL, P= 45:55 v/v AA:HCl, T= 65 min) and coffee (R= 0.01 g/mL, P= 100:0 v/v AA, T= 65 min). The extraction yielded pectin with ≥74% GalA, meeting USP/FCC pharmaceutical-grade criteria, with cocoa and coffee husk yields of ~7% and ~21%, respectively. Dialysis increased purity, raising molecular weight up to ~297000 Da and narrowing dispersity. Extracted pectin exhibited higher total phenolic and flavonoid contents than commercial citrus pectin and showed superior antioxidant capacity (ORAC up to 53.1 mg TE/g; DPPH up to 2420 mg TE/g), supported by metabolomic profiling that identified abundant antioxidant metabolites such as protocatechuic acid, trigonelline and catechol. In vitro assays with human dermal fibroblasts demonstrated cytocompatibility at 0.1 mg/mL, mild ROS-scavenging effects and selective modulation of inflammatory cytokines, with cocoa pectin reducing IL6 and dialyzed coffee pectin showing strong IL-6 suppression.
