When writing this botanical and historical review, it was necessary to get acquainted with the works of different authors from the XVII to the XXI century, written in Latin, old Spanish, old French, Spanish, French, German, Dutch, English and Russian. It shows the development of knowledge about growing on the American continents rubber-bearing trees, including their species definition and a botanical description. The main attention is paid to the Castilla elastica Cerv. from the Moraceae family, which served as a source of raw materials for the manufacture of an analogue of modern vulcanized rubber for ancient peoples of Mesoamerica and was then for many years the main rubber-bearing plant, whereas the priority have been given to Hevea brasiliensis (Wild. ex A. Juss.) Muell.-Arg. only after the beginning of plantation cultivation of this species in the end of XIX century. However, interest in Castilla did not completely disappear, and in the coming millennium, attempts were made to resume plantations. Sequencing of individual fragments of the nuclear and chloroplast genomes of Castilla species has also begun. The history of the appearance of the second erroneous name of this genus as Castilloa and the long process of returning the original name Castilla are described.

Once at the core of Romance philology, the teaching of Historical Romance Linguistics has all but vanished from university curricula Even though language change is constitutive for any natural language, most bachelor degree programs focus on synchronic studies these days Nevertheless, instead of arguing for the reintroduction of compulsory Old French or Old Spanish courses, this paper promotes another vision of Historical Linguistics in academic education In line with Christmann (1975) and Böckle / Lebsanft (1989), it will be shown that it is possible to include a solid introduction to Historical Linguistics in today's curricula and, at the same time, adapt it both to modern teaching conditions and the needs of bachelor degree students by taking the contemporary Romance languages as a starting point and applying a diachronic perspective on their features In this context, the recently published History of Spanish by Ranson / Lubbers Quesada (2018) will be presented as an example of a textbook that represents this approach in a nearly perfect manner.

Background: During the last 30 years an antimicrobial stewardship program (ASP) was implemented in a facility with periods of weakness. We aim to describe the history of the sustainability failure in the local ASP. Methods: A historical review was conducted using original data from the facility library and papers published. An analysis of factors related to the failure was conducted based on the Doyle approach. Results: The first ASP was implemented from 1989 to 1996 based on the international experiences and contributes to the improvement in the quality of prescription, reduction of 52% in cost and in the incidence of nosocomial infection. The second program restarts in 2008 and decline in 2015, while the third program was guided by the Pan-American Health Organization from 2019. This program, in progress, is more comprehensive than previous ones and introduced as a novel measure the monitoring of antibiotic prophylaxis in surgery. The factors related to the sustainability were considered including the availability of antimicrobials, the leader´s support, safety culture, and infrastructure. Conclusions: The history behind thirty years of experiences in antimicrobial stewardship programs has allowed us to identify the gaps that require proactive strategies and actions to achieve sustainability and continuous quality improvement.

AbstractRuins are a statement on the building materials used and the construction method employed. Casa Ippolito, now in ruins, is typical of 17th-century Maltese aristocratic country residences. It represents an illustration of secondary or anthropogenic geodiversity. This paper scrutinises these ruins as a primary source in reconstructing the building’s architecture. The methodology involved on-site geographical surveying, including visual inspection and non-invasive tests, a geological survey of the local lithostratigraphy, and examination of notarial deeds and secondary sources to support findings about the building’s history as read from its ruins. An unmanned aerial vehicle was used to digitally record the parlous state of the architectural structure and karsten tubes were used to quantify the surface porosity of the limestone. The results are expressed from four perspectives. The anatomy of Casa Ippolito, as revealed in its ruins, provides a cross-section of its building history and shows two distinct phases in its construction. The tissue of Casa Ippolito—the building elements and materials—speaks of the knowledge of raw materials and their properties among the builders who worked on both phases. The architectural history of Casa Ippolito reveals how it supported its inhabitants’ wellbeing in terms of shelter, water and food. Finally, the ruins in their present state bring to the fore the site’s potential for cultural tourism. This case study aims to show that such ruins are not just geocultural remains of historical built fabric. They are open wounds in the built structure; they underpin the anatomy of the building and support insights into its former dynamics. Ruins offer an essay in material culture and building physics. Architectural ruins of masonry structures are anthropogenic discourse rendered in stone which facilitate not only the reconstruction of spaces but also places for human users; they are a statement on the wellbeing of humanity throughout history.

This paper explores identity and the recursive impacts of cross-cultural colonial encounters on individuals, cultural materials, and cultural practices in 20th-century northern Australia. We focus on an assemblage of cached metal objects and associated cultural materials that embody both Aboriginal tradition and innovation. These cultural materials were wrapped in paperbark and placed within a ring of stones, a bundling practice also seen in human burials in this region. This ‘cache' is located in close proximity to rockshelters with rich, superimposed Aboriginal rock art compositions. However, the cache shelter has no visible art, despite available wall space. The site shows the utilisation of metal objects as new raw materials that use traditional techniques to manufacture a ground edge metal axe and to sharpen metal rods into spears. We contextualise these objects and their hypothesised owner(s) within narratives of invasion/contact and the ensuing pastoral history of this region. Assemblage theory affords us an appropriate theoretical lens through which to bring people, places, objects, and time into conversation.

Abstract The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different materials, operating at different wavelengths. In the UK, academia, industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications. This historical review looks at the contribution the UK has made to the advancement of the technology, the development of systems and components and their exploitation over the last 60 years.

Psoriasis is a chronic, inflammatory disease with a varying degree of clinical presentations. Managing psoriasis has always been arduous due to its chronicity and its propensity to relapse. Prior to the development of targeted biologic therapies, there were few effective treatments for psoriasis. Ancient psoriasis therapies included pinetar, plant extracts, psychotherapy, arsenic, and ammoniated mercury. In the 19th century, chrysarobin was developed. Then, in the early half of the 20th century, anthralin and coal tar were in widespread use. In the latter half of the 20th century, treatments were limited to topical first-line therapies, systemic drugs, and phototherapy. However, as the treatment of psoriasis has undergone a revolutionary change with the development of novel biologic therapies, patients with moderate to severe psoriasis have been able to avail therapies with high efficacy and durability along with an acceptable safety profile. This article is a brief historical review of the management of psoriasis prior to the inception of biologics and with the development of novel biologic therapies.

The importance of magnesite for the EU economy and industry is very high, making the understanding of their genesis for the exploration for new deposits a priority for the raw materials scientific community. In this direction, the study of the magnesite-hosting ultramafic rocks can be proved very useful. For the present study, ultramafic rock samples were collected from the magnesite ore-hosting ophiolite of the Gerakini mining area (Chalkidiki, Greece) to investigate the consecutive alteration events of the rocks which led to the metallogenesis of the significant magnesite ores of the area. All samples were subjected to a series of analytical methods for the determination of their mineralogical and geochemical characteristics: optical microscopy, XRD, SEM, EMPA, ICP–MS/OES and CIPW normalization. The results of these analyses revealed that the ultramafic rocks of the area have not only all been subjected to serpentinization, but these rocks have also undergone carbonation, silification and clay alteration. The latter events are attributed to the circulation of CO2-rich fluids responsible for the formation of the magnesite ores and locally, the further alteration of the serpentinites into listvenites. The current mineralogy of these rocks was found to be linked to one or more alteration event that took place, thus a significant contribution to the metallo- and petrogenetic history of the Gerakini ophiolite has been made. Furthermore, for the first time in literature, Fe inclusions in olivines from Greece were reported.

In the 12th and 13th centuries, the troubadours in Occitania and the trouvères in northern France composed songs with texts in the vernacular and monophonic melodies. For the troubadours, the vernacular was Old Occitan; for their northern counterparts, Old French. This difference in idiom is sometimes held to mark a distinction between two separate but analogous traditions of medieval song. The medieval practices of compiling multilingual lyric anthologies and of borrowing melodies seem instead to affirm the contiguity of song culture across different languages. The term “lyric” during this period typically designates a text set to melody, but not all manuscripts of troubadour and trouvère lyric preserve song melodies. Music survives for nearly half of the trouvère repertory (about three thousand songs) but only about 10 percent of the twenty-six hundred extant troubadour songs. The compositional period for troubadours and trouvères is conventionally defined rather rigidly as 1100–1300, and the songs themselves as strophic and monophonic. However, the troubadours and trouvères also composed in non-strophic genres (lais and descorts), and the trouvères composed in non-musical lyric genres (congés, dits) as well as in polyphonic forms. Adam de la Halle and Jehan de Lescurel, for example, produced small but significant collections of single-text polyphonic pieces. Of course, the composition of French and Occitan song also continued beyond 1300, albeit in different social and cultural contexts, by which point the long history of its study and reception had already begun. Some of the most important reference works, such as the Pillet-Carstens Bibliographie, date from the early 20th century and come from France and Germany, while Anglophone publications on troubadour and trouvère music only began to emerge in the second half of the 20th century. Modern scholars continually renew this material by bringing it into conversation with critical theory (Giving Voice to Love: Song and Self-Expression from the Troubadours to Guillaume de Machaut, cited under General Studies), feminist theory (Songs of the Women Trouvères, cited under Anthologies), and social history (The Owl and the Nightingale: Musical Life and Ideas in France 1100–1300, cited under Musical, Literary, Social, and Political Studies; The World of the Troubadours: Medieval Occitan Society, c. 1100-c.1300 and Parler d’amour au puy d’Arras: Lyrique en jeu, both cited under Regional Studies). The vibrancy in troubadour and trouvère scholarship also comes from interdisciplinary collaboration and exchange among musicologists, historians, paleographers, and literary scholars. Despite their shared primary sources, the fields of musicology and of literary studies have approached troubadour and trouvère material differently, and with different emphases. In part, these differences can be ascribed to the difficulty of defining a corpus of study, which does not always overlap for the two fields. The organization of this article echoes some of these tensions between older but fundamental reference works and newer directions of inquiry, and the sometimes separate, sometimes unified, treatment of troubadour and trouvère song.
