Active Design
Active Design is a set of building and planning principles that promote physical activity. Active design in a building, landscape or city design integrates physical activity into the occupants' everyday routines, such as walking to the store or making a photocopy. Active design involves urban planners, architects, transportation engineers, public health professionals, community leaders and other professionals in building places that encourage physical activity as an integral part of life. While not an inherent part of active design, most designers employing "active design" are also concerned with the productive life of their buildings and their building's ecological footprint.

Social Learning Tools
Social learning tools are tools used for pedagogical and andragogical purposes that utilize social software and/or social media in order to facilitate learning through interactions between individuals and systems. The idea of setting up "social learning tools" is to make education more convenient and widespread. It also allows an interaction between users and/or the software which can bring a different aspect to learning. People can acquire knowledge by distance learning tools, for instance, Facebook, Twitter, Khan Academy and so on. Social learning tools may mediate in formal or informal learning environments to help create connections between learners, instructors and information. These connections form dynamic knowledge networks. Social learning tools are used in schools for teaching/learning and in businesses for training. Within a school environment, the use of social learning tools can affect not only the user (student) but his/her caretaker as well as his/her instructor. It brings a different approach to the traditional way of learning which affects the student and his/her support circle. Companies also use social learning tools. They used them to improve knowledge transfer within departments and across teams. Businesses use a variety of these tools to create a social learning environment. They are also used in company settings to help improve team work, problem solving, and performance in stressful situations. Social learning tools are used for people who are willing to share their good ideas/thoughts with someone else. The ideas can be related to either the academic studies or any other daily skills that we want to share with others. Social learning tools connect learning to our daily lives. It creates a learning environment more truthful to today's society. There are a couple of common elements that should be present in a social learning tool. Technology should be involved to allow physical and cognitive learning. There should be interactions between the people who use the tool and interactions with the software. Another element is trust. Users should trust the software and what other people have created.

Respirator
A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres, including particulate matter such as dusts and airborne microorganisms, as well as hazardous fumes, vapours and gases. There are two main categories: the air-purifying respirator in which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respirator in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants. Air-purifying respirators range from relatively inexpensive single-use, disposable face masks sometimes referred to as a dust mask to more robust reusable models with replaceable cartridges often called a gas mask.

Photonic Crystals in Photovoltaics
Photonic crystals are artificial structures with a spatial periodicity of dielectric permittivity on the wavelength scale. These structures come in various materials and can be constructed in 1D, 2D, and 3D formats, providing a wide range of options for customizing the material's optical properties and potential applications. One of promising application is in the field of solar energy. By utilizing PCs in the design of solar cells, researchers can enhance their performance and efficiency by improving e.g., light management and increasing light trapping capabilities. This innovation can potentially significantly improve solar cells' effectiveness of all generations.

Arms Export Control Act
The Arms Export Control Act of 1976 (Title II of Pub.L. 94–329, 90 Stat. 729, enacted June 30, 1976, codified at 22 U.S.C. ch. 39) gives the President of the United States the authority to control the import and export of defense articles and defense services. The H.R. 13680 legislation was passed by the 94th Congressional session and enacted into law by the 38th President of the United States Gerald R. Ford on June 30, 1976. The Act of Congress requires international governments receiving weapons from the United States to use the armaments for legitimate self-defense. Consideration is given as to whether the exports "would contribute to an arms race, aid in the development of weapons of mass destruction, support international terrorism, increase the possibility of outbreak or escalation of conflict, or prejudice the development of bilateral or multilateral arms control or nonproliferation agreements or other arrangements." The Act also places certain restrictions on American arms traders and manufacturers, prohibiting them from the sale of certain sensitive technologies to certain parties and requiring thorough documentation of such trades to trusted parties. When the President is aware of the possibility of violations of the AECA, the law requires a report to Congress on the potential violations. U.S. Immigration and Customs Enforcement (ICE) conducts an industry outreach program called the Project Shield America to prevent foreign adversaries, terrorists, and criminal networks from obtaining U.S. munitions and strategic technology.

Treatments for Minimizing Sewage Sludge
Similar to other types of waste, sewage sludge (SS) must be minimized, not only to respect the European Directive 2018/851 on waste, but also because the cost of sludge management is approximately 50% of the total running costs of a wastewater treatment plant (WWTP). Usually, minimization technologies can involve sewage sludge production with three different strategies: (i) adopting a process in the water line that reduces the production of sludge; (ii) reducing the water content (dewatering processes) or (iii) reducing the fraction of volatile solids (stabilization).

Seductive Details
Seductive details are often used in textbooks, lectures, slideshows, and other forms of educational content to make a course more interesting or interactive. Seductive details can take the form of text, animations, photos, illustrations, sounds or music and are by definition: (1) interesting and (2) not directed toward the learning objectives of a lesson. John Dewey, in 1913, first referred to this as “fictitious inducements to attention.” While illustrated text can enhance comprehension, illustrations that are not relevant can lead to poor learning outcomes. Since the late 1980s, many studies in the field of educational psychology have shown that the addition of seductive details results in poorer retention of information and transfer of learning. Thalheimer conducted a meta-analysis that found, overall, a negative impact for the inclusion of seductive details such as text, photos or illustrations, and sounds or music in learning content. More recently, a 2020 paper found a similar effect for decorative animations This reduction to learning is called the seductive details effect. There have been criticisms of this theory. Critics cite unconvincing and contradictory evidence to argue that seductive details do not always impede understanding and that seductive details can sometimes be motivating for learners.

Toshiba Libretto
The Libretto was a line of subnotebook computers designed and produced by Toshiba. The line was distinguished by its combination of functionality and small size, squeezing a full Windows PC into a device the size of a paperback book. The first Libretto model, the Libretto 20, was released on April 17, 1996 (in Japan only), with a volume of 821 cm3 (50.1 cu in) and weighing just 840 g (30 oz), making it by far, the world's smallest commercially available Windows PC at the time, and a trend the Libretto Range continued for many years. The original Libretto line was discontinued in Europe and the U.S. in 1999, but the production continued in Japan with the SS, FF and then the L series until 2002. The first L series Libretto (The L1) was released on 18 May 2001 (in Japan only) and the last (The L5) just 11 Months later on 24 April 2002. Production of all Librettos ceased from 2002 until the release of the Libretto U100 in 2005. It was a further five years before the Libretto returned again in 2010 with the limited-edition dual touch screen tablet W100 model.
