“…Ground penetrating radar (GPR) has become one of the key technologies in subsurface sensing and, in general, in non-destructive testing (NDT), since it is able to detect both metallic and nonmetallic targets. GPR for NDT has been successfully introduced in a wide range of sectors, such as mining and geology, glaciology, civil engineering and civil works, archaeology, and security and defense. …”

“…In addition, mining and postprocessing of raw materials may accelerate weathering processes and chemically alter the environment through, for example, acidification or pollution by heavy metals. Environmental damage brings the necessity for ecosystem reconstruction in affected areas. …”

“…The contributions collected in this book aim at gaining a deeper understanding on the relationship between the underlying structural order and the resulting physical properties in several illustrative aperiodic systems, including the border line between QCs and related complex metallic alloys, hierarchical superlattices, electrical transmission lines, nucleic acid sequences, photonic quasicrystals, and optical devices based on aperiodic order designs…”

“…New technologies and equipment, which improve and modify optical laser parameters, contribute to better absorption of laser energy by metals or powder surfaces and allow for multiplying laser power that can positively influence the industrial spread of the laser in mass production and advance the existing manufacturing methods. …”

“…Based on the geochronological analysis, the magnetic susceptibility anthropogenic sources of metals in south-eastern Baltic lake sediments from the Neolithic to the Medieval Age were determined. …”

“…The third chapter is dedicated to concrete specific solutions with strong practical relevance and high transfer potential for digitized work and learning in the construction sector and in the metal sector. The final fourth chapter presents comprehensive and freely accessible online offers such as a media pool for educational purposes, a learning media database and a hybrid learning system with a virtual 3D building model. …”

“…Environmental Protection Agency (EPA) defines PM as a mixture of extremely small particles and liquid droplets comprising a number of components, including 'acids (such as nitrates and sulfates), organic chemicals, metals, soil or dust particles, and allergens (such as fragments of pollen and mold spores)'. …”

“…La Mancha es un mar de tierra aquietado por la pobreza, de secos labrantíos, y si acaso se distingue algo son alguno que otro humilde aprisco asustado de casas de nombre que suena con los puros metales del yunque castellano. No es vivir en peligro la hazaña de don Quijote, es morir en peligro, adentrarse en el denso boscaje de la tristeza y amancer sin ninguna fe en días vencidos, derrota tras derrota. …”

“…Un año después en Asturias, fundará la Sociedad de Obreros en Hierro y demás Metales de Gijón. Y en 1913 será nombrado secretario general del Sindicato Obrero Metalúrgico Asturiano. …”

“…Em 1913, ingresó en la Sociedad de Obreros en Hierro y demás Metales " El Porvenir " de Madrid, vinculada a la UGT. …”

“…La expansión de España, Francia, Inglaterra y Provincias Unidas en los territorios de Norteamérica a partir del siglo XVI tiene su origen en múltiples causas: la búsqueda de metales preciosos, el asentamiento de nuevas poblaciones fuera del alcance de la presiones políticas y religiosas dominantes en Europa, la demanda de recursos naturales, el comercio de pieles, la necesidad de puertos seguros que garantizasen las rutas de navegación, el afán evangelizador, la gloria personal y los intereses geoestratégicos fueron algunos de los motivos. …”

“…Far from the exclusivity established by the metropolis in the relations with its respective colonies, what actually existed was a global trading network within which money, precious metals, merchandise and flows of information circulated, legally at times and tolerated on other occasions and, always, with the mechanisms established to enforce the law proving insufficient to put an end to the transactions conducted outside the law. …”
