As the climate crisis has progressed, scientists have begun to ask, "How does a rapidly warming ecosystem impact human behavior?" As aggression scholars and non-professional environmentalists, it has become increasingly clear that the impact of the climate crisis, without intervention, will dramatically increase humans' exposure to risk factors known to cause aggressive and violent behavior. This article describes a model that explains the indirect and direct effects of the climate crisis on aggression and violence [...]

Developing adsorbents with appreciable morphology will create new approaches for better phosphate adsorption performance. This study aims to investigate the design of an adsorbent by impregnating silver nanoparticles (AgNPs) onto calcium oxide-activated carbon (CaO-AC). The Ag/CaO-AC nanocomposite was used as an adsorbent to remove phosphate. Batch adsorption studies were performed to evaluate the effects of adsorbent dose, initial phosphate concentration, contact time, and pH on removing phosphate from an aqueous [...]

This article quantifies the recycling potential of the metallic materials that make up three-phase induction motors. The data on the use of electric motors by type and power determines that the most significant recycling potential lies in this low-voltage motor which powers up to 75 kW. The work aims to show the possibility of such recycling in the European Union (EU). The metals used to make the various parts of the induction motor and the main recycling methods that allow their reuse are listed. It evaluates whic [...]

This research aims to model and compare two strategies for locating new hydrogen refueling stations (HRS) in a context of high uncertainty on H2 demand and on the spatial distribution of demand points. The first strategy S1 represented by an agent-based model integrating a particle swarm optimization metaheuristic consists of finding the best HRS locations by adapting to the real evolution of the demand. A second strategy S2 consists in solving a classical capacitated p-median problem based on H2 consumption foreca [...]

A multicopper oxidase, laccases catalyze the four-electron reduction of the substrate with the use of molecular oxygen. Laccases are abundant in nature and can be found in virtually every form of life on the planet. Generally speaking, laccases are classified into three types: blue, white, and yellow. Plant, bacterial and fungal laccases all have the same trinuclear copper site for substrate reduction. Non-phenolic as well as phenolic molecules are both capable of being catalyzed by this enzyme. Laccases are used i [...]

Legumes provide several ecological services to agroecosystems, but there is a lack of references on services related to N flows for a wide range of legume crops. N2O emissions were measured in two field experiments using a two-year legume-cereal crop sequence. In the first year (2014 and 2016), different legume crops were grown (lupin, pea, fava bean, common bean, soybean, chickpea) and compared to fertilized cereals (barley and sorghum). Once the seeds were harvested and the residues incorporated in the soil, unfe [...]

The chemical regeneration of exhausted granular activated carbon (GAC) from a water treatment plant to produce dialysis water used in hemodialysis treatments for chronic renal disease patients from a general Hospital of Ciego de Avila province, Cuba, was investigated. Activated carbon (AC) exhausted mainly by inorganics (Ca (Ca-chelates), Mg and Na) was regenerated using hydrochloric acid and acetic acid (one regeneration cycle). Solutions of 5%, 10%, 15% and 20%(v/v) as well as four contact times (2 h, 4 h, 6 h an [...]

Continued industrialization, urbanization and ecological destruction have caused significant environmental problems, particularly increased water pollution. Introducing harmful organic and inorganic effluents into watercourses has limited the supply and accessibility of safe and affordable drinking water. There is an urgent need to find green and sustainable abatement solutions for water remediation, many based on nanoparticles. The primary objective of this review is to explore and have a comprehensive discussion [...]

Understanding the urban environment and the health status of residents is necessary for appropriate administrative services and regional management. This study used indicator scores derived from the area statistics of cities in the Tokyo metropolitan area to identify factors that affect health status. Indices were classified into two groups: health-related and non-health-related. The index values of each group served as the observed variables and were statistically standardized. The relationship between the two gro [...]

The present research was part of a cross-sectional project involving children aged 8 to 10 years in Porto, Portugal. The project involved a first research part at primary schools where the health tests and a questionnaire were performed and a second research part concerning environmental conditions. Two groups emerged from the health questionnaire answers: one group that reported “asthma diagnosed by a doctor” and/or “wheezing or whistling in the chest during last 12 months” and another that answered negatively to [...]
