Business Process Outsourcing
Business process outsourcing (BPO) is a subset of outsourcing that involves the contracting of the operations and responsibilities of a specific business process to a third-party service provider. Originally, this was associated with manufacturing firms, such as Coca-Cola that outsourced large segments of its supply chain. BPO is typically categorized into back office outsourcing, which includes internal business functions such as human resources or finance and accounting, and front office outsourcing, which includes customer-related services such as contact centre services. BPO that is contracted outside a company's country is called offshore outsourcing. BPO that is contracted to a company's neighbouring (or nearby) country is called nearshore outsourcing. Often the business processes are information technology-based, and are referred to as ITES-BPO, where ITES stands for Information Technology Enabled Service. Knowledge process outsourcing (KPO) and legal process outsourcing (LPO) are some of the sub-segments of business process outsourcing industry.

Dragonchain
Dragonchain is a hybrid blockchain platform for enterprises and developers. It was originally developed at The Walt Disney Company in Seattle in 2014 and then open-sourced in 2016. Despite extensive speculation, there is no current relationship between Disney and Dragonchain. The open source code is maintained by the Dragonchain Foundation. The commercial blockchain platform is maintained by the commercial entity named The Dragon Company. Dragonchain is a public/private hybrid blockchain platform that allows integration with other blockchain protocols, legacy systems, oracles, and API's. Developers can use existing smart contracts from the library or write their own smart contracts to build (decentralized) blockchain applications in known languages. In 2020, Medek Health launched Covid SafePass with the City of Apopka, using Dragonchain blockchain solutions in line with the FDA guidance on Digital Health Policies and Public Health Solutions for COVID-19.

Medicinal Mushrooms and COVID-19
Many mushroom species are consumed as food, while significant numbers are also utilised medicinally. Mushrooms are rich in nutrients and bioactive compounds. A growing body of in vitro, in vivo, and human research has revealed their therapeutic potentials, which include such properties as anti-pathogenic, antioxidant, anti-inflammatory, immunomodulatory, gut microbiota enhancement, and angiotensin-converting enzyme 2 specificity. The uses of medicinal mushrooms (MMs) as extracts in nutraceuticals and other functional food and health products are burgeoning. COVID-19 presents an opportunity to consider how, and if, specific MM compounds might be utilised therapeutically to mitigate associated risk factors, reduce disease severity, and support recovery. As vaccines become a mainstay, MMs may have the potential as an adjunct therapy to enhance immunity.

RNA Vaccine
A ribonucleic acid (RNA) vaccine or messenger RNA (mRNA) vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. The vaccine transfects molecules of synthetic RNA into immune cells, where the vaccine functions as mRNA, causing the cells to build foreign protein that would normally be produced by a pathogen (such as a virus) or by a cancer cell. These protein molecules stimulate an adaptive immune response which teaches the body to identify and destroy the corresponding pathogen or cancer cells. The mRNA is delivered by a co-formulation of the RNA encapsulated in lipid nanoparticles which protect the RNA strands and help their absorption into the cells. Reactogenicity, the tendency of a vaccine to produce adverse reactions, is similar to that of conventional non-RNA vaccines. People susceptible to an autoimmune response may have an adverse reaction to RNA vaccines. The advantages of RNA vaccines over traditional protein vaccines are ease of design, speed and lower cost of production, and the induction of both cellular and humoral immunity. RNA vaccines, such as the Pfizer–BioNTech COVID-19 vaccine, have the disadvantage of requiring ultracold storage before distribution; other mRNA vaccines, such as the Moderna, CureVac, and Walvax COVID-19 vaccines, do not require such ultracold storage temperatures. In RNA therapeutics, mRNA vaccines have attracted considerable interest as COVID-19 vaccines. In December 2020, Pfizer–BioNTech and Moderna obtained approval for their mRNA-based COVID-19 vaccines. On 2 December, the UK's Medicines and Healthcare products Regulatory Agency (MHRA) became the first medicines regulator to approve an mRNA vaccine, authorizing the Pfizer–BioNTech vaccine for widespread use. On 11 December, the US Food and Drug Administration (FDA) issued an emergency use authorization for the Pfizer–BioNTech vaccine and a week later similarly approved the Moderna vaccine. The use of RNA in vaccines has occasioned substantial misinformation in social media, wrongly claiming that the introduction of RNA alters a person's DNA.

Fundamentals of Microwave Technology in Catalyst Production
The fundamentals and mechanisms of microwave irradiation are fundamentals of microwave technology. Two mechanisms of the microwave technology, electric field and magnetic field heating, which make microwave irradiation unique and potentially viable in numerous fields are included as well. These aspects are essential to be understood prior to investigating microwave-absorbing catalysts for the production of biofuel. With the outstanding benefit of microwave heating, the active sites of catalysts or entire catalysts can be heated selectively to enhance the catalytic performance. In the case of microwave-unabsorbing material, selective heating of the catalyst will result in heat transfer to organic solvents and eventually increases the conversion yield. The kinetic rate by microwave irradiation was higher than conventional heating by 1.15 times.

Liquid Cooling and Ventilation Garment
A Liquid Cooling Garment (LCG) is a form-fitting garment that is used to remove body heat from the wearer in environments where evaporative cooling from sweating and open-air convection cooling does not work, or the wearer has a biological problem that hinders self-regulation of body temperature. A Liquid Cooling and Ventilation Garment (LCVG) has additional crush-resistant ventilation ducts, which draw moist air from the wearer's extremities, keeping the wearer dry. In a fully enclosing suit where exhaled breathing air can enter the suit, the exhaled air is moist and can lead to an uncomfortable feeling of dampness or wetness. While this technology is most commonly associated with space suits, it is also used in a wide range of Earth-bound applications where open-air cooling is difficult or impossible to achieve, such as fire fighting, working in a steel mill and increasingly by surgeons during long or strenuous procedures.
