Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.

2015

Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…

Quantification of Platinum in Edible Mushrooms Using Voltammetric Techniques

2021

Edible mushrooms are a food source with interesting nutritional values. The chief objective of this research was to develop a consistent method for the quantitative ultra-trace analysis of Pt in mushrooms, which is complex because it cannot be readily quantified by common analytical procedures. This research is one of the first analytical methods to establish Pt amount in these vegetables. In this research, 28 different edible mushroom samples from Italy were investigated. Determination of Pt in mushrooms was completed using Differential Pulse Voltammetry (DPV). In this study, we applied the standard addition method because there are no certified reference mushrooms containing platinum grou…

Recovery of mobility function and life-space mobility after ischemic stroke: the MOBITEC-Stroke study protocol

2020

Abstract Background Stroke is a major cause of disability and stroke incidence increases with age. Stroke frequently results in permanent limitations of mobility, and, consequently, the need for the help of others in activities of daily living. In order to optimize rehabilitative efforts and their functional outcomes, detailed knowledge of the functional recovery process, regarding mobility, is needed. Objectives of the MOBITEC-Stroke study are: 1.) To characterize mobility, including lower extremity physical function (LEPF) and life space (the geospatial extent of all of a person’s movements), and changes in mobility within the first year after stroke. 2.) To identify and characterize subg…

First report on the helminthfauna of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula

2016

Summary Information about the prevalence of helminth parasites of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula is almost non-existent and there is no reliable data reported from Spain. Fourteen A. flavicollis from the Erro River valley (Navarre, Spain) were examined for endoparasites, between February 2001 and July 2002. Thirteen specimens (92.9 %) of the total sample were parasitized by at least one of the following six helminth species: one trematode (Corrigia vitta), one cestode (Taenia parva larvae) and four nematodes (Trichuris muris, Calodium hepaticum, Heligmosomoides polygyrus and Syphacia stroma). This is the first report about the helminthfauna of A. fla…

Los nuevos derechos sociales: El derecho al cuidado como fundamento del pacto constitucional

2016

ResumenNos encontramos ante un momento histórico y político que sugiere una revisión constitucional, con necesidades específicas y diferentes a las de 1978. Existen nuevas demandas que exigen que se revise el pacto constitucional. Algunas afectan directamente al catálogo de derechos, especialmente a los llamados derechos sociales, y se refieren por un lado, a la necesidad de otorgar a los derechos sociales ya reconocidos la consideración de fundamentales con todo lo que ello conlleva; y por otro, a la necesidad de crear nuevos derechos. El previsible aumento de personas necesitadas de cuidados, la escasez de servicios públicos para su asistencia, el tipo de cuidado informal prestado casi ex…

“I Like to Keep my Archaeology Dead”. Alienation and Othering of the Past as an Ethical Problem

2019

As archaeologists, we have to deal with the dead, and as David Clarke once said, we like to keep our archaeology dead. From an epistemological perspective, alienation from the dead seems almost inevitable; otherwise, we would only project today’s conditions onto the past. Therefore, the past must be, and must remain, a foreign country. These alienating processes have ethical implications, however, especially when it comes to the study of human remains. In this article, we analyze the structures within the scientific discipline of archaeology that normalize practices, such as the labeling of human bone material during excavations and the object-like display of skeletons in museums. We argue …

Some characterisations of groups in which normality is a transitive relation by means of subgroup embedding properties

2018

[EN] In this survey we highlight the relations between some subgroup embedding properties that characterise groups in which normality is a transitive relation in certain universes of groups with some finiteness properties.
