Lower and Middle Cambrian brachiopods from the Iberian Chains and Sierra Morena (Spain)
2021
Brachiopods from the Lower and Middle Cambrian of the Iberian Chains and Sierra Morena are described. The following taxa occur in the Iberian Chains: "Lingulella" sp., Redlichella cf. bohemica (Barrande), Dictyonina radioplicata sp. n., Micromitra sp., Trematobolus simplex (Vogel), Trematobolus borobiensis sp. n. and Jamesella sp. The taxa "Lingulella" sp. and Sibiria? sp. are reported from the Lower Cambrian of Sierra Morena. Brachiopods constitute several distinct associations: the relatively shallow water Trematobolus assemblage near the Lower-Middle Cambrian boundary interval is followed by the deeper DictyoninaRedlichella assemblage. The alternation of these assemblages permit us to i…
Authorship vs. Assemblage in Digital Media
2021
This chapter outlines an approach to complement current analyses on agencies of storytelling in digital environments. As our everyday life and meaning-making are increasingly entangled with digital platforms such as those of social media services, ways to critically examine digital media as an environment in literary theory are urgently needed – something that the existing analyses have mostly ignored. The particular point of contention in this chapter is the concept of authorship which has gone hand in hand with the understanding of authoring as a work of distinct agents, as it fails to acknowledge the ways in which human agency is entangled with more-than-human actors within digital envir…
Flexural behavior of external beam-column reinforced concrete assemblages externally strengthened with steel cages
2016
In this paper, an experimental study referring to the flexural behavior of full-scale external beam-column joints externally strengthened with steel angles and strips and subjected to cyclic reversal loading is presented. One control specimen and five other specimens having the same characteristics as the control specimen but strengthened with steel angles and strips along beams and columns, and characterized by different configurations of strengthening in the critical regions, were tested. The control specimen was designed with a weak column and strong beam to reproduce the most common cases of old frame structures in the Mediterranean area, which were designed only for gravity loads and a…
The unique fossil assemblage from the Lode Quarry (Upper Devonian, Latvia)
2001
The unique fossil fauna from the Lode clay quarry, lower Frasnian, Latvia, includes a diverse ichthyofauna of at least 15 taxa of agnathans and gnathostomes, representing most of the major taxa of Devonian vertebrates. Six new fish taxa (five species and one genus) were discovered during the last ten years. Exceptionally well-preserved juvenile fishes (<i>Asterolepis ornata, Lodeacanthus gaujicus</i>) provide unique data on ontogenetic change. Diverse arthropods are recorded. Parasitic platyhelminth remains in juvenile fish bodies is their first discovery in the fossil record, and represents the oldest parasitic association ever found. A complete faunal and floral list for the L…
Rabbit: More than the Magdalenian main dish in the Iberian Mediterranean region. New data from Cova de les Cendres (Alicante, Spain)
2020
Abstract In the Mediterranean Iberian region, rabbit has an important role in the human diet, mainly during the Final Upper Palaeolithic. The archaeological and experimental works about rabbit processing and consumption from the last years provide a wide and relevant framework. The site of Cova de les Cendres (Alicante, Spain) has a relevant role in the knowledge of the Iberian Upper Palaeolithic human subsistence, and offer a wide chronological sequence. The Magdalenian levels of Cendres provide a well-preserve archaeological assemblage of rabbit remains (ca. 90% of the total fauna) to study the human behaviour. The results show subsistence activities focus not only on meat and marrow imme…
Deciphering Biotic Interactions and Their Role in Soil Microbial Community Assembly and Functions
2022
Microbial communities play a key role in ecosystem functioning as well as in plant, animal, and human welfare. Their assembly relies on different processes commonly referred to as abiotic and biotic filters. Despite the widespread emphasis on abiotic filters in terrestrial ecosystems, a growing body of evidence suggests that interactions between microorganisms play a critical role in community assembly. However, the contribution of these interactions to microbial community assembly and the factors influencing them have not been clearly established. In most cases, biotic interactions between microorganisms have been investigated based on cocultures of a handful of strains, completely overloo…
A detailed analysis of the spatial distribution of Schöningen 13II-4 'Spear Horizon' faunal remains
2021
The Middle Pleistocene Schöningen 13II-4 'Spear Horizon' (Germany) is a key site for the study of human evolution, most notably for the discovery of Paleolithic wooden weaponry and evidence for developed hunting strategies. On the other hand, the 'Spear Horizon' offers an excellent opportunity to approach hominin spatial behavior, thanks to the richness of the archeological assemblage, its exceptional preservation, and the vast expanse of the excavated surface. Analyzing how space was used is essential for understanding hominin behavior at this unique open-air site and, from a wider perspective, for approaching how humans adapted to interglacial environments. In this article, we present an …
You realise you are better when you want to live, want to go out, want to see people: Recovery as assemblage
2021
Background: The lack of social and material perspectives in descriptions of recovery processes is almost common in recovery research. Aim: Consequently, we investigated recovery stories and how people with mental health and/or addiction challenges included social and material aspects in these stories. Method: We conducted focus group and individual interviews. We investigated how the participants narrated their stories and how they assembled places and people in their recovery stories. Results: We found that narratives of recovery became assemblages where humans and their environments co-exist and are interdependent. Conclusion: As such, narratives about recovery are about everyday assembla…
On chip optical nanotweezing for dielectric particles manipulation
2014
On chips optical nanocavities have become useful tools for trapping and manipulation of colloidal objects. In this thesis we study the nanocavities as building blocks for optical forces, trapping and handling of particles. Proof of concept of trapping dielectric microspheres appears as the starting point of the development of lab on chip. In the first chapter we go through the literature of optical forces in free space and integrated optics. The second chapter presents the experimental tools for the characterization of nanocavities and the set-up developed to perform optical measurements with the colloidal particles. The third chapter describes the proof-of-concept trapping of polystyrene p…
Una asociación peculiar de fusulinas en las calizas de Tanes, sección de Campo de Caso (Pensilvánico, Moscoviense superior; zona Cantábrica, España)
2021
The Campo de Caso section (eastern part of the Cantabrian Zone, NW Spain) exposes a middle to upper Moscovian (Middle Pennsylvanian) succession, up to 3500-m thick, consisting of marine shelfal and deltaic siliciclastic and shale deposits with numerous intercalated fossiliferous limestones. A limestone outcropping in the upper part of this section, close to the village of Tanes, has yielded a fusuline assemblage composed of species of the genera Eostaffella, Pseudonovella, Ozawainella, Pseudostaffella, Neostaffella, Schubertella, Fusiella, Taitzehoella, Fusulinella, Beedeina and Putrella . The specific composition of these genera, considered as a whole, indicates an early to mid- Myachkov…
