Pulsed Electric Fields' Impact on Milk's Nutritional Composition
Milk processing can cause the demolition of the milk fat globule membrane and induce interactions between whey protein and casein with membranes, leading to changes in pH, protein, and lactose content, as well as the destruction of vitamins and enzymes, hydrolysis of proteins and lipids, disruption of calcium and phosphorus equilibrium, and reduction of the cream layer. Pulsed electric fields (PEF) are gaining recognition in food processing due to their energy efficiency, minimal energy loss, flexibility, instantaneity, non-thermal nature, and environmental friendliness. It has also been found to reduce spoilage by microorganisms and the inactivation of undesirable enzymes, as well as its better retention of organoleptic and nutritional characteristics.

Survivability Assessment
Survivability assessment can be defined as the method by which the penetration performance of a protective material is measured. The key metric here is how effective the material is at dissipating energy throughout its molecular matrix, thereby protecting the material’s integrity and providing enhanced protection to the user from both ballistic and non-ballistic threats.

Application of Non-Destructive Testing Techniques to Characterize Nanocarriers
The synthesis of tailored and highly engineered multifunctional pharmaceutical nanocarriers is an emerging field of study in drug delivery applications. They have a high surface-area-to-volume ratio, aiding the targeted drug’s bio-distribution and pharmacokinetic properties. Therefore, the characterization of nanocarriers is critical for understanding their physicochemical properties, which significantly impact their molecular and systemic functioning. To achieve specific goals, particle size, surface characteristics, and drug release properties of nanocarriers must be managed. An overview of the applications of non-destructive testing techniques (NDTT) to reveal the characteristics of nanocarriers, considering their surface charge, porosity, size, morphology, and crystalline organization. The compositional and microstructural characterization of nanocarriers through NDTT, such as dynamic light scattering, X-ray diffraction, confocal laser scanning microscopy, ultraviolet-visible spectroscopy, scanning electron microscopy, atomic force microscopy, and nuclear magnetic resonance spectroscopy, have been comprehensively reviewed. Furthermore, NDTT is only used to characterize physicochemical parameters related to the physiological performance of nanocarriers but does not account for nanocarrier toxicity. Hence, it is highly recommended that in the future, NDTT be developed to assess the toxicity of nanocarriers. In addition, by developing more advanced, effective, and precise techniques, such as machine vision techniques using artificial intelligence, the future of using NDTT for nanocarrier characterization will improve the evaluation of internal quality parameters.

DEC 3000 AXP
DEC 3000 AXP was the name given to a series of computer workstations and servers, produced from 1992 to around 1995 by Digital Equipment Corporation. The DEC 3000 AXP series formed part of the first generation of computer systems based on the 64-bit Alpha AXP architecture. Supported operating systems for the DEC 3000 AXP series were DEC OSF/1 AXP (later renamed Digital UNIX) and OpenVMS AXP (later renamed OpenVMS). All DEC 3000 AXP models used the DECchip 21064 (EV4) or DECchip 21064A (EV45) processor and inherited various features from the earlier MIPS architecture-based DECstation models, such as the TURBOchannel bus and the I/O subsystem. The DEC 3000 AXP series was superseded in late 1994, with workstation models replaced by the AlphaStation line and server models replaced by the AlphaServer line.

Door-Opening Drones
Doorknob accessories, wheelchair-mounted door-opening accessories, door-opening robots, and door-opening drones—were used to group the various technologies for manually opening doors. Drones are unmanned aerial vehicles (UAVs) with a wide range of applications, including product delivery, asset inspection, search and rescue, law enforcement and military services, disaster management, and emergency medical services. Drones are emerging as safe alternatives to humans in applications involving inaccessible environments or dangerous scenarios. In cases of medical emergencies, when a person is stuck in remote locations and an ambulance is unable to reach a patient in time, medical drones are being used for emergency medical services. Door-opening drones are unmanned aerial vehicles (UAVs) equipped with the capability to open doors.
