Summary

Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today, it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems. Environmental studies are incorporating more of the social sciences in order to understand human relationships, perceptions and policies towards the environment. This entry collection features information about design and technology for improving environmental quality in every aspect.

Peptide Phytohormones
Various plant peptide hormones play a role in the defense from pathogens and herbivores and also in the interaction with beneficial microorganisms. Some families of peptide phytohormones have exclusively protective functions and are among the components of plant immunity, whereas other members of peptide phytohormones mostly play a role in the regulation of plant growth, but can be also involved in the defense response or plant–microbe interactions.

IoT Intrusion Detection Taxonomy
The taxonomy includes (1) IoT security attacks, (2) IoT architecture layers, (3) intrusion-detection systems for IoT, (3) DL techniques used in the IoT IDSs, (4) common datasets used in the evaluation of the DL systems, and (5) their classification strategies. The different areas included in the taxonomy are in various ways interconnected as root causes of IoT security vulnerabilities in IoT and/or solutions to counter such causes.

Spent Lithium-Ion Batteries Recycling
An urgent demand for recycling spent lithium-ion batteries (LIBs) is expected in the forthcoming years due to the rapid growth of electrical vehicles (EV). To address these issues, various technologies such as the pyrometallurgical and hydrometallurgical method, as well as the newly developed in-situ roasting reduction (in-situ RR) method were proposed in recent studies.

Seaweeds in Pig Nutrition
In order to reduce the antimicrobials used in livestock, it's important to find natural and sustainable molecules that boost animal performance and health. Brown seaweeds seem to be a promising dietary intervention in pigs in order to boost the immune system, antioxidant status and gut health.

Retinoic Acid and Retinaldehyde Dehydrogenase
Retinoic acid (RA) is an important biological metabolite synthesized from the retinol content (known as “vitamin A”) via a sequential cellular process in the retinoid signaling pathway (RSP). RSP-mediated RA biosynthesis is a vital physiological process in chordates, since RA interacts with the nuclear receptor superfamily, namely nuclear RA receptors (RARs) and retinoid X receptors (RXRs), bound to the RA response elements (RAREs) in the promoter region of RA target genes. Retinaldehyde dehydrogenases (RALDH) belongs to the oxidoreductase family and plays a critical role in RA synthesis from the retinaldehyde content; therefore, this enzyme is considered to be one of the key regulators of RA-related retinol metabolism and embryonic development.

Pd Nanoparticles
Among transition metal nanoparticles, palladium nanoparticles (PdNPs) are recognized for their high catalytic activity in a wide range of organic transformations that are of academic and industrial importance. The increased interest in environmental issues has led to the development of various green approaches for the preparation of efficient, low-cost and environmentally sustainable Pd-nanocatalysts.

Gaseous Emissions from the Composting Process
Compost can be used in agricultural activities due to its various positive impacts on the physical and chemical properties of the soil, meanwhile reducing utilization of inorganic fertilizers. Composting has also negative environmental impacts, some of them of social concern. This is the case of composting atmospheric emissions, especially in the case of greenhouse gases (GHG) and certain families of volatile organic compounds (VOC).

Ag-Decorated/Loaded Gas Sensors
Ag is one of the cheapest noble metals which is extensively used in the decoration or doping of semiconducting metal oxides (SMOs) to boost the overall gas-sensing performances of nanostructured SMOs. This is due to the electronic and chemical sensitization of Ag nanoparticles.

Urban Vulnerability
Urban vulnerability can be defined as the process produced by the combination of many disadvantaged dimensions in which any possibility of upward social mobility, and overcoming social condition exclusions, is extremely hard to achieve. Usually, the more vulnerable and distressed areas lack basic services and have a higher number of obsolete buildings, unfavorable social characteristics, vulnerable people, and more prominent gender differences.
