The Metropolitan Area of Barcelona is a densely populated region in the North-East of the Iberian Peninsula. Infrastructures in this area play a significant role in the economy of this part of Europe. The combination of the Mediterranean Sea and the complex topography is responsible for the occurrence of severe weather events in this location and the surrounding areas. The use of remote sensing data in an hourly resolution allows the identification and characterization of those severe episodes, helping in determini [...]

The presence of shopping malls causes a social, economic, and environmental impact. The bibliometric analysis is a valuable method used to dentify published research papers, and understand historic information published in scientific journals. This method can be used to carry out qualitative and quantitative analyses of scientific production on a specific subject. This analytical method primarily focuses on analyzing the bibliometric study of the solid waste management method used in shopping malls. A small number [...]

Hydrogels are three-dimensional, hydrophilic networks of polymers with a high water absorption capacity. We investigated the removal of monovalent cationic dye, methylene blue, from aqueous solutions by a polyvinyl alcohol/Sodium alginate/Starch mix hydrogel to discover a solution to the environmental waste-water problem. By applying a gamma radiation dose from a Co-60 source without adding a hazardous cross-linker, a novel PVA/SA/Starch mix hydrogel was synthesized. The effects of factors like irradiation dose and [...]

The management of healthcare waste (HCW) presents a significant environmental and public health challenge, aggravated by gaps in current Brazilian federal regulations. This study provides a comprehensive analysis of specific state and municipal legislation on HCW, comparing it with ANVISA Resolution No. 222/2018 and CONAMA Resolution No. 358/2005 to ascertain whether local regulations enhance management practices and can act as supplementary instruments to federal guidelines. The methodology was structured into thr [...]

This study evaluates three shading configurations designed and tested in a preliminary stage of responsive shading device development. The strategy is based on trigonometric relationships focused on solar angles at any given moment. The configurations are thus related to the ratio of the window area shaded by a responsive brise-soleil that provides 0%, 50%, or 100% shading of the indoor space, based on the daylight needs and the indoor thermal control realized. Shading simulations were performed for Pomona, Califor [...]

Extended Producer Responsibility (EPR) places liability, physical, financial, and/or informative responsibility for a product throughout its life cycle on its producer. Implementing such schemes is expected to result in many environmental and social benefits. Yet, academic and practitioner discussions on the mechanisms focus on environmental impacts, whereas social dimensions of EPR are often side-lined. This short communication contributes to addressing this gap by establishing a research agenda for the justice di [...]

Decomposition of spent coffee grounds (SCGs), a byproduct of brewing coffee, in disposed landfill sites releases significant amounts of potent greenhouse gases. This study aims to investigate the maximum recycling proportions of SCGs, a nonconventional filler material, for permeable interlocking concrete paving (PICP) blocks. These blocks have a porous structure that helps mitigate surface ponding while maintaining sound structural performance. Using Scanning Electron Microscope image analysis, the water absorbency [...]

The first step in managing an entity's carbon emissions involves measurement as 'what gets measured gets managed' and measurement lies at the heart of carbon management. The study of carbon management is important to all stakeholders as it enables calculation of emissions that can help determine opportunities for emissions reductions to address climate change which can improve energy efficiency and brand reputation. Alphabet is an interesting company to study given its main commercial activities relate to the devel [...]

Soil is a very complex medium made of minerals, organic matter, microorganisms, air, and water. Vibrational spectroscopy techniques are exceptionally well-suited to be used with portable and hand-held devices. In this study, NIR spectroscopy was applied using portable instrumentation and the holistic Aquaphotomics approach to identify the differences in three Mediterranean soil profiles from Sardinia (Italy). The soil samples (95) collected from alluvial and loess-sampling sites in the three study areas of North Sa [...]

Environmentally motivated voluntary diet modifications are the focus of much research and public discourse. Yet the nuanced multi-faceted, multi-dimensional nature of agriculture-earth interactions, and limited public environmental knowledge likely combine to undermine the efficacy of environmentally motivated dietary shifts, squandering limited good will. To counter this, here I devise two related indices for crudely estimating importance of various environmental impacts of alternative dietary choices. Based on th [...]

This project demonstrates how to use existing syntheses of many decades of historical social science research to produce empirically derived land-use maps in a GIS for large regions for a specific target year at a resolution appropriate to the calibration of existing anthropogenic land-cover change (ALCC) models. Disagreement among the outputs of various ALCC models results from differing estimates of population and assumptions about how much food a given population requires and the productivity per unit area of va [...]

Regressive Autism [RA] is a subtype of autism spectrum disorder (ASD) that manifests as the loss of previously acquired developmental milestones and skills. Early life dysregulation of neurodevelopment due to exposure to toxic metals has been associated with ASD, but the underlying biological mechanisms by which metals influence neurodevelopment remain unclear. We explored the potential role of thimerosal or ethylmercury on neurite formation and oxytocin receptor (OXTR) modulation in four human-developing neuronal [...]

Cyanobacteria blooms alter aquatic ecosystems and occur frequently in shallow prairie lakes, which are predicted to increase in salinity as the regional climate becomes hotter and drier. However, flat landscapes that experience depression bottom salinity with high concentrations of sulfate in addition to sodium and chloride, may mitigate nutrient increases or even inhibit cyanobacteria growth. Cyanobacteria can dominate shallow lakes with low N:P ratios because many cyanobacteria species fix dissolved N2, whether d [...]

The practice of reconciliation ecology in urban environments relies heavily on urban green space as the primary source of vegetated habitat in cities. However, most cities lack the quantity, connectivity, and accessibility of green space needed to provide essential ecosystem services for the health, well-being, and resilience of human and non-human species. In reaction to urban densification and the increasing frequency and severity of climate change impacts, this study argues that architecture could strategically [...]

The Contingent Valuation (CV) Method, like other stated preference techniques, seeks to measure economic preferences for public goods. Throughout the development and application of this non-market procedure, the accuracy of the measured preferences has been front-and-centre among practitioners and potential users. The most important issue of debate has been the extent to which the method can reliably measure economic preferences. In this article, a new methodology is described that enables multiple indicators of la [...]

Gaseous elemental mercury (GEM) was monitored in the atmosphere of a coastal site situated in the Northern Aegean Sea of Greece from August 2014 to January 2015. The selected sampling site is seldom impacted by human activities. Thus, it was possible to study the processes involved in natural terrestrial, aquatic, and atmospheric environments. The diurnal and monthly variations in the concentration of GEM as well as the factors influencing these variations were determined. The GEM concentrations were found to be in [...]

Currently, almost half of the human population is at risk of acquiring dengue. Other emerging pathogens affecting human populations transmitted by Aedes (Stegomyia) aegypti are chikungunya and Zika viruses. People who live in poor areas are more susceptible to be infected by these diseases. The lack of selective garbage collection and inadequate water storage are important factors in the dynamics of vector-borne transmission. This study took place in Estrutural City, the poorest city in Brasilia, Brazil, which host [...]
