Sustainable Architecture–What’s Next?
Sustainable architecture encompasses more than energy efficiency, zero carbon dioxide (CO2) emission or renewable energy use in the built environment. It also needs to alleviate overall impacts on the natural environment or ecosystem that surrounds it. It may be argued that primitive vernacular architecture (architecture without architects) built and operated using local techniques and resources alone can be considered to be sustainable. Yet later, after the 1992 Rio Conference and its declarations, more specific definitions emerged putting weight on the rational use of land area, materials and energy, preferably local, as well as area efficient planning, economy and recyclability. The advantage of this is to reduce the ecological footprint of buildings and the climate gas emissions from a sector that represents 35–50 percent of global climate gas emissions, depending on how one counts. This paper clarifies concepts, questions cemented truths and points a way forward by asking; what’s next?

Epidemiology of Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. About 10% of latent infections progress to active disease which, if left untreated, kills about half of those affected. Typical symptoms of active TB are a chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically called consumption due to the weight loss. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is based on chest X-rays, as well as microscopic examination and culture of body fluids. Diagnosis of latent TB relies on the tuberculin skin test (TST) or blood tests. Prevention of TB involves screening those at high risk, early detection and treatment of cases, and vaccination with the bacillus Calmette-Guérin (BCG) vaccine. Those at high risk include household, workplace, and social contacts of people with active TB. Treatment requires the use of multiple antibiotics over a long period of time. Antibiotic resistance is a growing problem with increasing rates of multiple drug-resistant tuberculosis (MDR-TB). As of 2018, one quarter of the world's population was thought to have latent infection with TB. New infections occur in about 1% of the population each year. In 2018, there were more than 10 million cases of active TB, resulting in 1.5 million deaths and making it the number one cause of death from an infectious disease at that time. As of 2018, most TB cases occurred in the regions of South-East Asia (44%), Africa (24%) and the Western Pacific (18%), with more than 50% of cases being diagnosed in eight countries: India (27%), China (9%), Indonesia (8%), the Philippines (6%), Pakistan (6%), Nigeria (4%) and Bangladesh (4%). The number of new cases each year has decreased since 2000. About 80% of people in many Asian and African countries test positive while 5–10% of people in the United States population test positive by the tuberculin test. Tuberculosis has been present in humans since ancient times.

Tank Steering Systems
Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both. Half-track vehicles avoid this by combining steerable wheels and fixed-speed tracks. Early steering systems were adopted from tracked work vehicles, generally using a clutch to reduce power to one track, causing it to slow down. These designs have numerous problems, notably when climbing hills or running at high speed, as the reduction in power causes the overall speed to slow. Delivering power to both tracks while turning them at different speeds is a difficult design problem. A series of more advanced designs were introduced, especially through World War II, that maintained power to both tracks during steering, a concept known as regenerative steering. Some also allowed one track to move forward while the other reversed, allowing the tank to spin in place, a concept known as neutral steering. The first really successful system was the British double differential design of 1924, which was copied by both the United States and Germany. Most modern Western designs use a variation of the double differential, while Soviet designs preferred to use two separate transmissions in a single housing. Systems using electric motors with variable speed controls have been tried on a number of occasions, but have not entered widespread service.

Carbon-based Materials for Hydrogen Storage
Carbon in its various forms (e.g., nanotubes, fullerenes, graphene) create a family of substances that enable the storage of large amounts of hydrogen in a reversible manner, which is confirmed by both computer simulations and experimental results.The main contraindication to using hydrogen as an energy source in mobile applications is still the low gravimetric density achieved by the available systems (according to the recommendations of the US Department of Energy, it should be 6 wt.%).

Technologies in Adaptive Dynamic Building Envelopes
Adaptive Dynamic Building Envelope (ADBE) is the term used to describe envelope systems that increase the adaptability of the building skin toward changing ambient conditions, resulting in better energy efficiency and thermal comfort. ADBEs exploit the benefits of passive and active technologies that manage the energy and mass transfer between building and outdoor environment. There is a range of technologies that an ADBE can incorporate to enhance a building’s energy performance. According to their usage, they can be sorted into four categories, i.e., technologies for energy harvesting, technologies affecting heat transfer, technologies for air conditioning, and technologies for storage systems. ADBEs vary from one another based on their level of active-passiveness, and user controllability. The first characteristic is the level of how active or passive the technologies used in the final ADBE product perform. The second characteristic is the level of occupant interaction with the envelope, meaning if the user has the ability to operate some functions on the ADBE manually, or through the usage of building energy management systems.

Malacostraca
Malacostraca (from New Latin; from grc μαλακός (malakós) 'soft', and όστρακον "shell") is the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, amphipods, mantis shrimp and many other, less familiar animals. They are abundant in all marine environments and have colonised freshwater and terrestrial habitats. They are segmented animals, united by a common body plan comprising 20 body segments (rarely 21), and divided into a head, thorax, and abdomen.

Maya
Maya (/ˈmɑːjə/; Devanagari: माया, IAST: māyā), literally "illusion" or "magic", has multiple meanings in Indian philosophies depending on the context. In later Vedic texts, māyā connotes a "magic show, an illusion where things appear to be present but are not what they seem"; the principle which shows "attributeless Absolute" as having "attributes". Māyā also connotes that which "is constantly changing and thus is spiritually unreal" (in opposition to an unchanging Absolute, or Brahman), and therefore "conceals the true character of spiritual reality". In the Advaita Vedanta school of Hindu philosophy, māyā, "appearance", is "the powerful force that creates the cosmic illusion that the phenomenal world is real." In this nondualist school, māyā at the individual level appears as the lack of knowledge (avidyā) of the real Self, Atman-Brahman, mistakingly identifying with the body-mind complex and its entanglements. In Hinduism, māyā is also an epithet for goddess Lakshmi, and the name of a manifestation of Lakshmi, the goddess of "wealth, prosperity and love". In Buddhist philosophy, Māyā is invoked as one of twenty subsidiary unwholesome mental factors, responsible for deceit or concealment about the nature of things. Maya is also the name of Gautama Buddha's mother.

Haskell (Programming Language)
Haskell (/ˈhæskəl/) is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research and industrial application, Haskell has pioneered a number of programming language features such as type classes, which enable type-safe operator overloading. Haskell's main implementation is the Glasgow Haskell Compiler (GHC). It is named after logician Haskell Curry. Haskell's semantics are historically based on those of the Miranda programming language, which served to focus the efforts of the initial Haskell working group. The last formal specification of the language was made in July 2010, while the development of GHC has expanded Haskell via language extensions. The next formal specification (As of 2020). On 29 October 2021 GHC2021 was released in GHC version 9.2.1. Haskell is used in academia and industry. (As of May 2021), Haskell was the 28th most popular programming language by Google searches for tutorials, and made up less than 1% of active users on the GitHub source code repository.

Prestressed Concrete Girders
Prestressing methods were used to realize long-span bridges in the last few decades. For their maintenance, dynamic nondestructive procedures for identifying prestress losses were mainly developed since serviceability and safety of Prestressed Concrete (PC) girders depend on the effective state of prestressing. In fact, substantial long term prestress losses can induce excessive deflections and cracking in PC bridge girders. However, old unsolved problematics exist since a variation in prestress force does not significantly affect the vibration responses of such PC girders. As a result, this makes uncertain the use of natural frequencies as appropriate parameters for prestress loss determinations. Thus, amongst emerging techniques, static identification based on vertical deflections has preliminary proved to be a reliable method. In fact, measured vertical deflections take accurately and instantaneously into account the changes of structural geometry of PC girders due to prestressing losses. Given the current state of methodologies, the manuscript represents a state-of-the-art review of some important works on determining prestress losses. The attention is principally focused on a static nondestructive method, and a comparison with dynamic ones is elaborated.

FDG-PET/CT in the Monitoring of Lymphoma Immunotherapy Response
Cancer immunotherapy is a type of cancer treatment that uses the immune system to fight cancer cells. Some of these treatments stimulate the immune system, while others prime the immune system to identify better and target cancer cells. In parallel with the implementation of cancer immunotherapy, therapy-specific FDG PET/CT response criteria were explicitly designed specifically for that purpose. FDG PET/CT plays a key role in the newly developed response criteria, and several FDG PET/CT-based criteria have been proposed to address all patterns of response to therapy, including indeterminate response, pseudoprogression, and hyperprogression using several metrics, such as SUV, MTV, and TLG. This research aims to discuss the effects and side effects of cancer immunotherapy and to correlate this with the proposed criteria and relevant patterns of FDG PET/CT in lymphoma immunotherapy as applicable. Additionally, the latest updates and future prospects will be explored.

Dextran
Dextran is an exopolysaccharide (EPS) synthesized by lactic acid bacteria (LAB) or their enzymes in the presence of sucrose. Dextran is composed of a linear chain of d-glucoses linked by α-(1→6) bonds, with possible branches of d-glucoses linked by α-(1→4), α-(1→3), or α-(1→2) bonds, which can be low (<40 kDa) or high molecular weight (>40 kDa). The characteristics of dextran in terms of molecular weight and branches depend on the producing strain, so there is a great variety in its properties. Dextran has commercial interest because its solubility, viscosity, and thermal and rheological properties allow it to be used in food, pharmaceutical, and research areas.
