TiO2 for Removal of VOCs
Purification of air from the VOCs (Volatile Organic Compounds) by the photocatalytic process has been confirmed to be very perspective. Although many various photocatalysts have been prepared and studied so far, TiO2 is still the most commonly used, because of its advantageous properties such as non-toxicity, relatively low cost and high stability. Surface modifications of TiO2 were extensively proceeded in order to increase photocatalytic activity of the photocatalyst under both UV and visible light activations. High yield of VOCs decomposition can be achieved on TiO2, depending on its structure and preparation method. The contact time of reactant with the active sites of TiO2 surface will determinate the efficiency of the photocatalytic process. Although VOCs decomposition can occur under weak UV light, more intensive UV irradiation will guarante complete mineralisation process.

Digital and Smart Cities
Mobility is notoriously a key aspect of our modern economy and humans' way of life. In an edge situation such as the current coronavirus pandemic, transportation is one of the first affected mechanisms of a city. In our paper, we highlight the potential of operations research and computational intelligence tools for cities' services. The contributions involves aspects of optimization, internet-of-thing and internet-of-value (brought with concepts of Blockchain). When we sum up all these tools, it becomes possible to envision the potential that emerging software and systems can bring to society, associated with the wave of innovation surroundings the smart cities.

Endocrine-Disrupting Compounds
The continual detection of endocrine-disrupting chemicals (EDCs) (ng/L or µg/L) in water and wastewater has attracted critical concerns among the regulatory authorities and general public, due to its associated public health, ecological risks, and a threat to global water quality. Presently, there is a lack of stringent discharge standards regulating the emerging multiclass contaminants to obviate its possible undesirable impacts.

Terrorist and Built Environment
Terrorist impacts have been increasing over time in many countries, being one of the most significant threats for the Built Environment (BE), intended as a network of open spaces (streets, squares) and facing buildings, and their users. Due to the relevance of the perpetrator “will” and the quickness of actions, Terrorism is assimilable to Sudden Onset Disasters (SUOD). BE and its morpho-technological features can be inherently prone or resilient to terrorism risk. The analysis of Risk Mitigation and Reduction Strategies (RMRSs) can support the safety of BE from a sustainable point of view, above all when they transform the existing urban environments.

Mk F3 155mm
The 155 mm self-propelled gun Mk F3, or the Canon de 155 mm Mle F3 Automoteur (Cn-155-F3-Am), was developed in the early 1950s by the French Army to replace their American M41 Gorilla 155mm self-propelled guns. The Mk F3 is the smallest and lightest 155 mm motorized gun carriage ever produced, and because of its size and low cost it has found considerable success on the export market. Constructed on a modified AMX-13 light tank chassis, the Mk F3 is novel in incorporating room inside for only two of the eight required crewmen (the others riding in support vehicles). This allows the 155 mm gun to be placed on a smaller chassis than that employed by other armies, but exposes the outside crew members to enemy fire and other hazards.

Reticle
A reticle, or reticule also known as a graticule, is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight, spotting scope, theodolite, optical microscope or the screen of an oscilloscope, to provide measurement references during visual inspections. Today, engraved lines or embedded fibers may be replaced by a digital image superimposed on a screen or eyepiece. Both terms may be used to describe any set of patterns used for aiding visual measurements and calibrations, but in modern use reticle is most commonly used for weapon sights, while graticule is more widely used for non-weapon measuring instruments such as oscilloscope display, astronomic telescopes, microscopes and slides, surveying instruments and other similar devices. There are many variations of reticle pattern; this article concerns itself mainly with the most rudimentary reticle: the crosshair. Crosshairs are typically represented as a pair of perpendicularly intersecting lines in the shape of a cross, "+", though many variations of additional features exist including dots, posts, concentric circles/horseshoes, chevrons, graduated markings, or a combination of above. Most commonly associated with telescopic sights for aiming firearms, crosshairs are also common in optical instruments used for astronomy and surveying, and are also popular in graphical user interfaces as a precision pointer. The reticle is said to have been invented by Robert Hooke, and dates to the 17th century. Another candidate as inventor is the amateur astronomer William Gascoigne, who predated Hooke.

Fusil Automatique Modèle 1917
The Fusil Automatique Modèle 1917 (English: Model 1917 Automatic Rifle) (also called the RSC M1917 ) was a gas-operated, semi-automatic rifle that the French Army placed in service during the latter part (1917) of World War I. It was chambered in then-standard 8mm Lebel, the rimmed cartridge used in other French Army infantry weapons of the time. Altogether, the French National Armories (primarily MAS (Manufacture d'Armes de St Etienne) and MAT (Manufacture d'Armes de Tulle) had manufactured 86,000 RSC M1917 rifles when their production run ended in late November 1918. However very few have survived in fully functional, semi-automatic condition and those have become highly sought-after collectibles.
