Green Social Work Practice in Rural Community
Social work interventions in rural communities feature a spectrum of interventions, from supporting residents’ health and well-being to advancing rural community social development and advocating for policy improvement. In the current global context of climate change, these efforts have been conducted through three major social work practice fields (practice with clients, research, and policymaking), addressing environmental justice and sustainability in rural community development; however, there is a paucity of nuanced understanding of current rural community-driven social work interventions pertaining to climate change and its social consequences. Generally, the foundation of social work interventions associated with climate change, disasters, and other crises is understood as green social work (GSW), namely, social work practitioners are integral to enhancing local adaptation and promoting sustainability practices in the face of increasing climate-related extreme events. GSW, which forms a theoretical framework, supports the understanding of the urgent need for social work interventions to address environmental justice and sustainability in rural communities, contributing to climate adaptation and disaster risk reduction, eventually promoting building resilient and sustainable rural communities.

Methyl Iodide
Methyl iodide, also called iodomethane, and commonly abbreviated "MeI", is the chemical compound with the formula CH3I. It is a dense, colorless, volatile liquid. In terms of chemical structure, it is related to methane by replacement of one hydrogen atom by an atom of iodine. It is naturally emitted by rice plantations in small amounts. It is also produced in vast quantities estimated to be greater than 214,000 tons annually by algae and kelp in the world's temperate oceans, and in lesser amounts on land by terrestrial fungi and bacteria. It is used in organic synthesis as a source of methyl groups.

Air Quality during Covid-19 Lockdown
Air pollution exposure is one of the greatest risks to health worldwide. It is estimated to be responsible for about 4.2 million deaths around the world every year owing to many serious diseases such as heart disease, stroke, acute and chronic respiratory diseases, and lung cancer. The WHO guideline limits are exceeded in several areas around the world, and it is estimated that about 90% of the world’s population is exposed to high air pollution levels, especially in low- and middle-income countries. The COVID-19 pandemic has forced governments to implement severe mobility restriction measures to limit the spread of the virus. This represented a unique opportunity to study the impact of mobility on urban air quality. Several studies which have investigated the relations between the quality of the air and such containment measures have shown the significant reduction of the main pollutants in the urban environment so to encourage the adoption of new approaches for the improvement of the quality of air in the cities. The aims of this entry are both a brief analysis and a discussion of the results presented in several papers to understand the relationships between COVID-19 containment measures and air quality in urban areas.

Mechanical Properties of BCC-Structured High-Entropy Alloys
A new metallurgical strategy was introduced to develop advanced materials with outstanding performance—high-entropy alloys (HEAs). Today, HEAs contain five or more multiple principle metallic elements in equal or near-equal atomic percentages. HEAs’ four core effects—high configurational entropy, sluggish diffusion, severe lattice distortion, and the cock-tail effect—are mainly responsible for their various physical and mechanical properties. HEAs present promising properties, such as high strength and fracture toughness at room temperature and high temperatures and have excellent wear resistance, and corrosion resistance, along with high-temperature oxidation.

Ketamine and Driving, Cognitive, and Motor Ability
Ketamine is a medication that has many medical purposes but also has been used illicitly by people for its dissociative properties. While driving under the influence of drugs, drivers are more likely to be involved in and cause more accidents than drivers who do not drive under the influence.  A study with ketamine and a ketamine-like medication, rapasitnel, showed that those who were given ketamine experienced more sleepiness and had decreased self-reported motivation and confidence in their driving abilities. Moreover, there seem to be significant differences in the acute versus persistent effects of ketamine, as well as the anesthetic versus subanesthetic doses, both in terms of effects and outcomes. These divergent effects complicate the clinical uses of ketamine, specifically involving driving, drowsiness, and cognitive abilities.

Smart Materials
The introduction of smart materials (SMs) will become increasingly relevant as biomedical technologies progress. Smart materials sense and respond to external stimuli (e.g., chemical, electrical, mechanical, or magnetic signals) or environmental circumstances (e.g., temperature, illuminance, acidity, or humidity), and provide versatile platforms for studying various biological processes because of the numerous analogies between smart materials and biological systems.

Web Television
Web television is original episodic online video content produced for broadcast on the Internet via the World Wide Web. The phrase "web television" is also sometimes used to refer to Internet television in general, which includes Internet-transmission of programs produced for both online and traditional terrestrial, cable, or satellite broadcast. Web television content includes web series such as Carmilla, Husbands, Red vs. Blue, Teenagers, The Lizzie Bennet Diaries, and Video Game High School, among hundreds of others; original miniseries such as Dr. Horrible's Sing-Along Blog; animated shorts such as those of Homestar Runner; and exclusive video content that supplements conventional television broadcasts. The current major distributors of web television are Amazon, Crackle, Hulu, Netflix, Newgrounds, Roku, and YouTube. Examples of web television production companies include: Generate LA-NY, Next New Networks, Revision3, and Vuguru. In 2008, the International Academy of Web Television, headquartered in Los Angeles, formed in order to organize and support web television actors, authors, executives, and producers. The organization also administers the selection of winners for the Streamy Awards. In 2009, the Los Angeles Web Series Festival was founded. Several other festivals and award shows have been dedicated solely to web content, including the Indie Series Awards and the Vancouver Web Series Festival. In 2013, in response to the shifting of the soap opera All My Children from broadcast to web television, a new category for "Fantastic web-only series" in the Daytime Emmy Awards was created. Later that year, Netflix made history by earning the first Primetime Emmy Award nominations for web television series, for Arrested Development, Hemlock Grove, and House of Cards, at the 65th Primetime Emmy Awards. Hulu earned the first Emmy win for Outstanding Drama Series, for The Handmaid's Tale at the 69th Primetime Emmy Awards.

Incompressible Navier Stokes Equations
A closely related problem to The Clay Math Institute "Navier-Stokes, breakdown of smooth solutions here on an arbitrary cube subset of three dimensional space with periodic boundary conditions is examined. The incompressible Navier-Stokes Equations are presented in a new and conventionally different way here, by naturally reducing them to an operator form which is then further analyzed. It is shown that a reduction to a general 2D N-S system decoupled from a 1D non-linear partial differential equation is possible to obtain. This is executed using integration over n-dimensional compact intervals which allows decoupling. Here we extract the measure-zero points in the domain where singularities may occur and are left with a pde that exhibits finite time singularity. The operator form is considered in a physical geometric vorticity case, and a more general case. In the general case, the solution is revealed to have smooth solutions which exhibit finite-time blowup on a fine measure zero set and using the Gagliardo-Nirenberg inequalities it is shown that for any non zero measure set in the form of cube subset of 3D there is finite time blowup.

End-of-Life Vehicles Recycling
End-of-life vehicle (ELV) recycling is a process that spends energy and could be an energy source as well. This part of energy recovering depends on many different factors related to the broad and local aspects of ELV recycling. The ELV recycling process is consuming energy from different energy sources (electrical, fossil), however, this consumption is lower in relation to energy consumption during the production of new vehicle parts from the very beginning. ELVs have, in the first phase, been considered as an environmental problem, which must be solved through many decision-making approaches, directives, and standards. Accordingly, it may be concluded, that this issue is very complex since it includes a lot of relations concerning ELV recycling, as well as broad infrastructure and socio-economic environment factors. On the other hand, there is not enough relevant and reliable information related to the ELV recycling and energy recovery through ELV recycling process. This information can be obtained through user responses, financial analysis, business analysis, or some government body relevant information sources. Due to new regulations related to ELV recycling, the responsibility of manufacturers is becoming increasingly important. They are obligated to design and revise their processes and adapt them to new legislation norms.

Renewable Energy and Energy Storage Systems
The use of fossil fuels has contributed to climate change and global warming, which has led to a growing need for renewable and ecologically friendly alternatives to these. It is accepted that renewable energy sources are the ideal option to substitute fossil fuels in the near future. Significant progress has been made to produce renewable energy sources with acceptable prices at a commercial scale, such as solar, wind, and biomass energies. Hybrid renewable energy systems are needed with good energy management to balance the various renewable energy sources’ production/consumption/storage.

Volunteering
Volunteering is generally considered an altruistic activity where an individual or group provides services for no financial or social gain "to benefit another person, group or organization". Volunteering is also renowned for skill development and is often intended to promote goodness or to improve human quality of life. Volunteering may have positive benefits for the volunteer as well as for the person or community served. It is also intended to make contacts for possible employment. Many volunteers are specifically trained in the areas they work, such as medicine, education, or emergency rescue. Others serve on an as-needed basis, such as in response to a natural disaster.
