Comparison of monolithic and microparticulate columns for reversed-phase liquid chromatography of tryptic digests of industrial enzymes in cleaning p…
2011
Abstract Enzymes of several classes used in the formulations of cleaning products were characterized by trypsin digestion followed by HPLC with UV detection. A polymeric monolithic column (ProSwift) was used to optimize the separation of both the intact enzymes and their tryptic digests. This column was adequate for the quality control of raw industrial enzyme concentrates. Then, monolithic and microparticulate columns were compared for peptide analysis. Under optimized conditions, the analysis of tryptic digests of enzymes of different classes commonly used in the formulation of cleaning products was carried out. Number of peaks, peak capacity and global resolution were obtained in order t…
Marcos mentales: ¿marcos morales? Deliberación pública y democracia en la neuropolítica
2018
En este trabajo trato de abordar el concepto de «marco mental» como clave para entender la concepción que la neuropolítica tiene de la deliberación pública y la democracia. En un primer lugar expondré los puntos centrales de las teorías de Jonathan Haidt y George Lakoff sobre el marco mental y la deliberación pública. Después pondré en relación la idea del marco mental con el concepto de «marco referencial» de Taylor. Finalmente, analizaré críticamente el modelo de deliberación pública y de democracia que cabe extraer del concepto de marco mental en la neuropolítica.
Influence of gravity vector on eye movement elicited by linear acceleration.
1991
When the body/head motion is sensed by otolith organs, they respond not only to the resultant acceleration of the motion but also to the gravitational force. We investigated the influence of the gravity vector on the otolithic-ocular reflex caused by motion in normal subjects. The sled type linear accelerator, moving back and forth with a frequency of 0.25 Hz and an amplitude of 2 m, generated right-left linear acceleration with a maximum magnitude of 0.5 g. We tested every subject under seven different postures: 1) 135 degrees forward tilted (F.T.), 2) 90 degrees F.T., 3) 45 degrees F.T., 4) upright sitting, 5) 45 degrees backward tilted (B.T.), 6) 90 degrees B.T., and 7) 135 degrees B.T. …
European vestibular experiments on the Spacelab-1 mission: 4. Thresholds of perception of whole-body linear oscillation.
1986
Thresholds for the detection of linear oscillatory motion at 0.3 Hz in the X, Y and Z body axes were determined during the flight of Spacelab-1 and on the ground pre- and post-flight, using the method of limits with a single staircase procedure. Pre-flight, Z axis thresholds (mean 0.077 ms-2) were significantly higher than X and Y thresholds (mean 0.029 ms-2). Measures obtained on three crew members in-flight exhibited thresholds greater, by a factor of 1.5-4.3, than those obtained pre-flight. Post-flight, two crew members had significantly elevated X and Y axis thresholds whereas the other two crew members had lowered thresholds in X, Y and Z axes. In general, thresholds had returned to pr…
The Cave of Vecchiuzzo: anthropology, paleopathology and hierarchy of the human group with a statistical overview (Petralia Sottana – Palermo, Italy)
2013
Lo scavo della Grotta del Vecchiuzzo fu il primo effettuato nelle Madonie (Sicilia centrooccidentale). Fin dalla sua scoperta avvenuta per mano di Collisani e Carapezza nel 1936, il ritrovamento di manufatti nel vano principale indicò che la grotta era stata abitata. Gli scavi, effettuati a partire dal 1937, indicarono che la grotta era stata adibita ad abitazione o forse a santuario e che era stata abitata intorno al terzo millennio a.C. I resti scheletrici, attribuiti ad almeno quindici individui, sono stati studiati dal punto di vista antropologico, antropometrico e paleopatologico, combinando metodologie tradizionali a quelle più moderne. Sui dati odontometrici raccolti è stata effettua…
The burial of Bad Dürrenberg, Central Germany: osteopathology and osteoarchaeology of a Late Mesolithic shaman's grave
2006
The isolated burial of Bad Durrenberg is one of the richest Mesolithic graves in Europe. Although it was excavated in the 1930s, new spectacular anthropological and archaeological evidence has emerged during a recent re-study. Firstly, we present here the results of an anthropological re-evaluation of certain features of the skull base and the foramen magnum. Our work has clearly established that the observable features are caused by an anatomical variation that also includes an atlar anomaly. This developmental variation possibly caused various neuropathological symptoms. The Bad Durrenberg burial consequently represents a unique case of the possible interpretation of abnormal behaviours i…
Sinistral transport along the Trans-European Suture Zone: detrital zircon–rutile geochronology and sandstone petrography from the Carboniferous flysc…
2010
AbstractThe Lower Carboniferous flysch of the Istanbul Zone in Turkey is an over 1500 m thick turbiditic sandstone–shale sequence marking the onset of the Variscan deformation in the Pontides. It overlies Lower Carboniferous black cherts and is unconformably overlain by Lower Triassic continental sandstones and conglomerates. The petrography of the Carboniferous sandstones and the geochronology and geochemistry of the detrital zircons and rutiles were studied to establish the provenance of the clastic rocks. The sandstones are feldspathic to lithic greywackes and subgreywackes with approximately equal amounts of quartz, feldspar and lithic clasts. The amount of quartz and lithic fragments d…
Mollusk carbonate thermal behaviour and its implications in understanding prehistoric fire events in shell middens
2018
Abstract Archaeological shell middens are particularly important for reconstructing prehistoric human subsistence strategies. However, very little is known about shellfish processing, especially when related to the use of fire for dietary and disposal purposes. To shed light on prehistoric food processing techniques, an experimental study was undertaken on modern gastropod shells (Phorcus lineatus). The shells were exposed to high temperatures (200–700 °C) to investigate subsequent mineralogy and macro- and microstructural changes. Afterwards, the three-pronged approach was applied to archaeological shells from Haua Fteah cave, Libya (Phorcus turbinatus) and from shell midden sites in the U…
Reflections on the Other Side. A Southern Iberia Origin for the First Pottery Production of Northern Morocco?
2021
Archaeological works in Morocco (the Spanish-Moroccan team) were funded by a European Research Council Advanced Grant AGRIWESTMED (Origins and spread of agriculture in the western Mediterranean region) coordinated by L.P.-CH. Processing works were performed thanks to a IJCI-2016-27812 -Spanish Ministry of Science, Innovation and Universities-Universidad de Granada, Juan de la Cierva-Incorporacion Agreement (2016, by RMMS), and by funding provided in the framework of project "Archaeobiology of the Neolithic of the Southern Iberian Peninsula" (NeArqBioSI) A-HUM-460-UGR18 by Consejeria de Economia, Conocimiento, Empresas y Universidad.
