Frying
Frying is one of the oldest unit operations to produce food products with a crisp texture, an aromatic flavour and a golden-brown colour. Deep-fried foods such as French fries, potato/veggie crisps are popular among consumers. Detailed insights into the frying process in terms of heat, mass (water and oil) and momentum transfers are outlined in this entry.

Talkboy
Talkboy is a line of handheld voice recorder and sound novelty toys manufactured by Tiger Electronics (now owned by Hasbro) in the 1990s. The Talkboy was originally conceived as a cassette recorder and player prop for the 1992 film Home Alone 2: Lost in New York. At the request of director John Hughes and 20th Century Fox, Tiger designed and built the prop, and was given permission by the movie studio to sell a retail version of the toy. Two cassette recorders modeled after the film prop were released in 1992 and 1993, respectively. The original model did not have the variable-speed voice changer of the film version and sold only moderately during the 1992 holiday shopping season. In April 1993, Tiger released the Deluxe model, which added the voice-changing feature. Following the release of Home Alone 2 on home video in July with an insert advertising the Deluxe Talkboy, interest in the toy spiked. Retailers had severely underestimated demand, and as a result the Deluxe Talkboy was one of the most highly sought-after toys during the 1993 holiday shopping season, selling out of stores across the United States. A pink version of the cassette recorder called "Deluxe Talkgirl" was released in 1995. The success of the Talkboy cassette recorders spawned a product line of electronic toys. Tiger transitioned to digital recorders for subsequent devices, using solid-state storage and adding sound effects, beginning with "Talkboy/Talkgirl F/X+" pens in 1995, which sold more than a million units in 45 days.

Smart Logistics in Industry 5.0
Given the importance of human centricity, resilience, and sustainability, the emerging concept of Industry 5.0 has pushed forward the research frontier of the technology-focused Industry 4.0 to a smart and harmonious socio-economic transition driven by both humans and technologies, where the role of the human in the technological transformation is predominantly focused on. The core elements of Industry 5.0 show that following the technology-centric transition of Industry 4.0, the societal, environmental, and human perspectives require more attention, which will yield significant impacts on logistics operations and management. For instance, the personalization of demands implies a personalized delivery system. Incorporating customers into the design requires highly intelligent CPS and system integration. Human–machine interaction triggers the interaction of various topics such as safety, human behavior, etc. Thus, there exist various challenges and approaches to addressing smart logistics issues in Industry 5.0.

Puma (IFV)
The Puma is a Germany infantry fighting vehicle (IFV) (Schützenpanzer or short SPz) designed to replace the aging Marder IFVs currently in service with the German Army. Production of the first batch of 350 vehicles began in 2010 and is scheduled for completion by the second quarter of 2021. A second batch of 210 Pumas has received funding. Mass production began on 6 July 2009. The companies responsible for this project are Krauss-Maffei Wegmann and Rheinmetall Landsysteme, who created a joint venture in the form of Projekt System Management GmbH (PSM). The Puma is one of the world's best-protected IFVs, while still having a high power-to-weight ratio.

Wireless Sensor Networks Architecture
Wireless sensor networks (WSNs) have taken a giant leap in scale, expanding their applicability to a large variety of technological domains and applications, ranging from the Internet of things (IoT) for smart cities and smart homes to wearable technology healthcare applications, underwater, agricultural and environmental monitoring and many more. This expansion is rapidly growing every passing day in terms of the variety, heterogeneity and the number of devices which such applications support. Data collection is commonly the core application in WSN and IoT networks, which are typically composed of a large variety of devices, some constrained by their resources (e.g., processing, storage, energy) and some by highly diverse demands. Many challenges span all the conceptual communication layers, from the Physical to the Applicational. In addition, the integrated unit architecture and the platform design can be subject to various stringent constraints. For example, size requirements can impose a strict constraint on the device design; low power consumption, low production cost, and self-operation can represent additional constraints.  Accordingly, the device architecture is fundamental and affects many other factors in the system. For example, power supply affects the life span; it also affects transmission range, memory, and processing unit, which in turn can affect the algorithms that can be executed on the device, etc.

Acrylic Bone Cements
Acrylic bone cements (ABC) are widely used in orthopedics for joint fixation, antibiotic release, and bone defect filling, among others. Most of the commercial ABCs available today consist of two components, one solid, based mainly on poly(methyl methacrylate) (PMMA), and one liquid, based on methyl methacrylate (MMA), which are mixed and, through the polymerization reaction of the monomer, transformed into a hardened cement paste.

Medical Implantable Antenna Technology
Implantable antennas are mandatory to transfer data from implants to the external world wirelessly. Smart implants can be used to monitor and diagnose the medical conditions of the patient. The dispersion of the dielectric constant of the tissues and variability of organ structures of the human body absorb most of the antenna radiation.
