This study comprises newly collected organic geochemical and petrological data on quality, quantity, maturity as well as the depositional environment of various organic matter-rich stratigraphic units in Morocco and the Central Congo Basin, DRC. In addition, 1D modeling was carried out for one locality in northern Morocco (Aït Moussa) and for two wells from the Central Congo Basin to obtain information on burial thermal and maturation history. For the Aït Moussa model, specific bulk kinetic parameters were used to evaluate the petroleum generation and timing. Paleozoic, Mesozoic and Cenozoic sediments were investigated from the Tarfaya Basin, southern part of Morocco/Western Sahara. Based on Corg measurements, samples with Corg >0.4 %, especially Late Cretaceous and Eocene sedimentswere considered for further geochemical and petrological analysis. Rock-Eval pyrolysis and biomarker assignment indicate a mixture of kerogen type I/II with an excellent petroleum generation potential of the Late Cretaceous and Eocene samples. More detailed analysis of Coniacian, and Late Turonian samples from a newly drilled well (Tarfaya Sondage No.2) in the Tarfaya Basin support the latter data. In contrast to the terrestrial influenced Santonian outcrop samples Coniacian and Santonian samples of Tarfaya Sondage No.2 revealed marine organic matter with a higher Corg content and a better quality of the organic matter, represented by alginite. Vitrinite reflectance measurements and various sterane and hopane ratios , as well as Tmax values of Rock-Eval pyrolysis indicate an early mature to immature range of the organic matter. Sulphur contents and Corg/TS support the theory of mainly oxygen-depleted waters, but it is still ambiguous whether the bottom waters were permanently anoxic or rather oxygen-deficient. Although these investigated source rocks of Late Cretaceous and Eocene age are excellent with respect to organic richness, kerogen quality and thickness, their low maturity poses a major problem for petroleum exploration. ...

Μετά από την επιδρομή των Ερούλων στην Αθήνα (267 μ.Χ.) η πόλη υπέστη μεταμορφώσεις αντίστοιχες αυτών που βίωσαν άλλες πόλεις του ελλαδικού χώρου κατά την ίδια εποχή. Όπως μαρτυρεί η οικοδομική δραστηριότητα, έως τα τέλη του 4ου αιώνα ένας εσωτερικός οχυρωματικός περίβολος κατασκευάστηκε, αρχαία δημόσια κτήρια εγκαταλείφθηκαν ή αποδομήθηκαν, εργαστήρια εγκαταστάθηκαν σε παλαιούς δημόσιους χώρους, ενώ το κέντρο βάρους της πόλης μεταφέρθηκε από τα δυτικά προς τα ανατολικά, στην περιοχή της σημερινής Βουλής και του Εθνικού Κήπου. ; After the Herulian invasion (267 CE) Athens was transformed just like other Greek cities were at that time. The analysis of the Athenian building activity shows that from the late 3rd to the 4th century an inner, reduced wall was constructed, ancient public buildings were abandoned or dismantled, workshops were installed in ancient public places, while the city's core was transferred from the west to the east, to the area of the nowadays Greek Parliament and the National Garden.

Beyond the ideological motivations based on the Holy War, in service of God, made in the public documents of the Late Middle Ages in order to justify the Christian conquests against Islam, the detailed analysis of the campaign of James II of Aragon against Nasrid Almeria in 1309-10 reveals a minimization of religious factors. On the contrary, it shows the importance of other political, social and economic motivations, fully linked to the expansionism inherent in every ruling feudal dynasty. ; Más allá de las motivaciones ideológicas basadas en la guerra santa, al servicio de Dios, realizadas en los documentos públicos de la baja edad media para justificar las conquistas cristianas contra el Islam, el análisis detallado de la campaña de Jaime II de Aragón contra la Almería nazarita en 1309-1310 revela una minimización del factor religioso y una elevación de otras causas políticas, sociales y económicas, plenamente vinculadas al expansionismo inherente a toda dinastía feudal gobernante.

In its decision A and S (judgment of 12 April 2018, case C-550/16, A et S v. Staatssecretaris van Veiligheid en Justitie), the Court of Justice of the European Union ruled – for the first time – on the relevant date for assessing the minority of an unaccompanied minor who reaches the age of majority in the course of their application for international protection. In this case, a young refugee had introduced an application for international protection while she was still minor of age but subsequently attained the age of majority during the procedure. In accordance with Art. 10, para. 3, let. a), of directive 2003/86 on the right to family reunification, she then applied for temporary residence permits for her relatives in the direct ascending line for the purposes of family reunification. Although she was granted asylum and thus fell within the scope of chapter V of directive 2003/86 laying down more favourable conditions for the family reunification of refugees, the directive was silent on whether she could have benefited from such conditions retroactively. Following its AG in this case, the Court avoided a formalistic interpretation and rather opted for a teleological approach of the more protective provisions of directive 2003/86. By doing so, it allowed their retroactive application to the young refugee and her parents. Through its interpretation, the Court restated its firm intention to protect the best interests of children – including third-country nationals – in the context of family reunification. Although it shows a definitely protective approach, the concrete impact of this decision appears to be somewhat limited in scope.

The question of how to conceptualize the role of technological innovations is of crucial importance for understanding the mechanisms and rhythms of long-term cultural change in prehistoric and early historic societies. The changes that have come about have often been modelled as gradual and linear, innovations have been considered positively as a progress in the development of humankind and the focus has been on the localisation of the origin of innovations and the routes of their spread. Appropriating Innovations goes beyond the current discussion by shedding light on condition that may facilitate the rapid spread of technological innovation and on processes involved in the integration of new technologies into the life world of the appropriating societies. In particular, papers concentrate on two key innovations, namely the transmission of the various components of the so-called "Secondary Products Revolution" in parts of the Near East and Europe during the 4th millennium BCE and the appropriation of early bronze casting technology, which spread from the Near East to Europe and China in the late 3rd and early 2nd millennium BCE.0Of particular interest is non-technological knowledge that is transmitted together with the technological, the latter being always deeply interconnected with the communication of social practices, ideas and myths. The acceptance of new technologies, therefore, requires the willingness to change existing world views and modify them due to the potentials and problems which are connected with the new technology. Contributions, therefore, concentrate on the conditions facilitating or hindering the spread of innovations and the transformative power of these innovations in the appropriating society

Heron's examination of the impact of new technology in Canada's Second Industrial Revolution challenges the popular notion that mass-production workers lost all skill, power, and pride in the work process.

The aim of this book is to review recent research and technical advances, including the progress in design codes, related to the engineering applications of light gauge metal sections made in carbon, high strength and stainless steel, as well as aluminium alloys. Included is a review of the new technologies for connections of light gauge metal members. Main advanced applications, for residential, non residential and industrial buildings and pallet rack systems are also covered. For the first time, this book takes into account all the metallic materials now used more and more for structural components. The book will be of great interest not only for researchers but also for design engineers faced to the use of new metallic materials in modern structural applications.

Foreign direct investment (FDI) in Brazil, started in the 19th century, a transition period between the Empire and the beginning of the Republic (1860-1913), when fdi theories had not yet been formulated. The British were the main investors worldwide, also in Brazil, responsible for developing essential sectors. In addition to the Europeans, the Americans also saw opportunities in the country, contributing later to the industries' installation. To better understand foreign investments in Brazil, as well as the installation of multinationals in the transition from the Empire to the Republic, we highlight the foreign investment process and the country's industrialization. The main contribution of this work is research pointing out the historical landmark of foreign investment in Brazil in the analyzed period, allowing to understand the country's urban and social development.
