STV Royston Grange
STV Royston Grange was a Houlder Line refrigerated cargo liner steamship that was built in England in 1959. In 1972 she collided with the tanker Tien Chee in the Río de la Plata. The resulting fire killed all 74 people aboard Royston Grange and eight people aboard Tien Chee. Royston Grange's burnt-out hulk was scrapped in Spain in 1979. Royston or Roystone Grange is an 18th-century farmstead next to the site of a medieval monastic grange at Ballidon in Derbyshire, England. Houlder Line had named ships after several English granges, including Royston, since the 1890s. This ship was the company's fifth and last Royston Grange.

Firearm (Tool)
A firearm is primarily a weapon, but can be used as a tool to project either single or multiple objects at high velocity through a controlled explosion. The firing is achieved by the gases produced through rapid, confined burning of a propellant. This process of rapid burning is technically known as deflagration. In older firearms, this propellant was typically black powder, but modern firearms use smokeless powder, cordite, or other propellants. Many firearms such as mortars do not have rifled bores to impart spin to the projectile for improved flight stability, such as is seen with firearms used as weapons, although some are rifled. The lack of rifling can prevent tangling of grappling hook lines, buoy lines, and such, although some firearms intended for use at the longest ranges in these applications are rifled.

Ground Based Strategic Deterrent
The Ground Based Strategic Deterrent (GBSD) is a future American land-based intercontinental ballistic missile system (ICBM) currently in the early stages of development. It is slated to replace the aging Minuteman III missiles, currently stationed in North Dakota, Wyoming, Montana, Nebraska and Colorado, from 2029 through 2075. In 2020, under the Trump administration, the Department of the Air Force gave the defense contractor, Northrop Grumman, a $13.3 billion sole-source contract for development of the GBSD after Boeing withdrew its proposal. Northrop Grumman's subcontractors on the GBSD include Lockheed Martin, General Dynamics, Bechtel, Honeywell, Aerojet Rocketdyne, Parsons, Textron and others.

Integrated Treatment of Agro-industrial Waste
This document reports a synthetic description of a research work in which a new integrated treatment was defined for the production of biofuel and the recovery of phosphorus compounds from agro-industrial residues. As the first step of the proposed process, anaerobic co-digestion was carried out to produce biogas by exploiting raw waste mixtures. Afterwards, the residual digestates were converted to syngas using supercritical wet gasification (SCWG. Finally, the liquid phases from SCWG were treated to recover the phosphorus content as MgKPO4×6H2O crystals. This integrated treatment could be a suitable approach to exploit agro-wastes because it can produce biofuel and valuable chemicals and generates a residual effluent with a very low polluting load

Semantic Support of Cultural Heritage
The usage of semantics is not new in cultural heritage disciplines. They are commonly used to define standards for meta-, para-, and provenance information for documenting and archiving. Examples of such standards are LIDO and MIDAS Heritage. These XML schema standards are still used in cultural heritage. In recent years, however, the emergence of the Semantic Web has provided the much-required boost to semantic frameworks and technologies. It also dictates how semantics are defined and used today. Techniques and tools that formalize semantics through formalized knowledge representations have become the norm in different fields applying semantics.

Road Traffic Noise Wall Design
Despite the long-term experience in the application of noise walls, the uncertainty in wall panel service life efficiency is almost equal between panels built from established and new materials, which are—because of the desire to increase the sustainability of noise walls—developing at an ever-faster pace. The presented meta-analysis of data collected during a systematic review of concrete, metal, and wood panels’ acoustic and non-acoustic characteristics, long term performance, and cradle-to-gate sustainability aims to reduce this uncertainty and support the process of noise wall design and management by shifting the emphasis in decision making from construction costs to the long-term sustainability of the road traffic noise mitigation project. The multi-criterial analysis showed that when choosing a panel, preference should be given to those using lightweight concrete materials.

Functionalised Graphene for Sensing Applications
The demand for gas detection is increasing nowadays. However, its fast detection at room temperature (RT) is a major challenge. Graphene is found to be the most promising sensing material for RT detection, owing to its high surface area and electrical conductivity. The high edge functionalized chemically synthesized graphene derivatives thin films are promising candidates to achieve a fast gas sensing response at room temperature. The high amount of edge functional groups is prominent for the sorption of analyte gas/vapor molecules.

Reversible Solid Oxide Cell
A reversible solid oxide cell (rSOC) is a solid-state electrochemical device that is operated alternatively as a solid oxide fuel cell (SOFC) and a solid oxide electrolysis cell (SOEC). Similarly to SOFCs, rSOCs are made of a dense electrolyte sandwiched between two porous electrodes. Their operating temperature ranges from 600°C to 900°C, hence they benefit from enhanced kinetics of the reactions and increased efficiency with respect to low-temperature electrochemical technologies. When utilized as a fuel cell, the reversible solid oxide cell is capable of oxidizing one or more gaseous fuels to produce electricity and heat. When used as an electrolysis cell, the same device can consume electricity and heat to convert back the products of the oxidation reaction into valuable fuels. These gaseous fuels can be pressurized and stored for a later use. For this reason, rSOCs are recently receiving increased attention due to their potential as an energy storage solution on the seasonal scale.

Microfluidics to Study Membrane Filtration
Membrane filtration processes are best known for their application in the water, oil, and gas sectors, but also in food production they play an eminent role. Filtration processes are known to suffer from a decrease in efficiency in time due to e.g., particle deposition, also known as fouling and pore blocking. Although these processes are not very well understood at a small scale, smart engineering approaches have been used to keep membrane processes running. Microfluidic devices have been increasingly applied to study membrane filtration processes and accommodate observation and understanding of the filtration process at different scales, from nanometer to millimeter and more. In combination with microscopes and high-speed imaging, microfluidic devices allow real time observation of filtration processes.

Co-CeO2 Catalyzed Water-Gas Shift Reaction
Co-CeO2 catalysts were synthesized by the different methods to derive the optimal synthetic method and to investigate the effect of the preparation method on the physicochemical characteristics of Co-CeO2 catalysts in the high-temperature water-gas shift (HTS) reaction. Co-CeO2 catalyst synthesized by a sol-gel method features the strong metal to support interaction and the largest amount of oxygen vacancies compared to other catalysts, which affects the catalytic activity. As a result, Co-CeO2 catalyst synthesized by the sol-gel method exhibited the highest WGS activity among the prepared catalysts, even in the severe conditions (high CO concentration: ~38% in dry basis and high gas hourly space velocity: 143,000 h−1).
