Laboratory phase‐contrast nanotomography of unstained Bombus terrestris compound eyes
2021
Imaging the visual systems of bumblebees and other pollinating insects may increase understanding of their dependence on specific habitats and how they will be affected by climate change. Current high-resolution imaging methods are either limited to two dimensions (light- and electron microscopy) or have limited access (synchrotron radiation x-ray tomography). For x-ray imaging, heavy metal stains are often used to increase contrast. Here, we present micron-resolution imaging of compound eyes of buff-tailed bumblebees (Bombus terrestris) using a table-top x-ray nanotomography (nano-CT) system. By propagation-based phase-contrast imaging, the use of stains was avoided and the microanatomy co…
Are Pseudosciences Like Seagulls? A Discriminant Metacriterion Facilitates the Solution of the Demarcation Problem
2019
In this article, I develop a philosophical framework, or ‘metacriterion’, for the demarcation of pseudoscience. Firstly, ‘gradualist demarcation’ is discussed in depth, considering an approach to t...
Las Cortes de 1443-1446 y la Hacienda de la villa de Alcoy
2004
By means of this work, we try to analyze how onerous were for the royal town's treasury the expenses derived from their attendance to Assemblies. For this, we are taking, as an example, the royal town of Alcoy in the <i>Cortes</i> of 1443. We have based our study in the <i>Proceso de Cortes</i> and in municipal sources.<br><br>Mediante este trabajo, pretendemos analizar el peso que tenían en la hacienda de las villas reales los gastos derivados de su asistencia a Cortes. Para ello tomaremos como ejemplo la villa de Alcoy en las Cortes de 1443-1446, basando nuestro análisis en el Proceso de Cortes y en fuentes municipales.
Las Cortes de Martín el Humano (1401-1407) y su repercusión en la Hacienda de la ciudad de Valencia.
2004
The general purpose of this paper is, towards municipal source knowledge, to study Treasury incidence of Cortes council, designed by King Martin of Aragon in the city of Valencia between 1401 and 1407. Cortes books of account register some files related to complaints about the <i>Cortes</i> meeting (embassies and aids to the king...), wages (receivers, notary public, bailiffs...), the <i>Cortes</i> development (documents copy and shipment, reading of <i>fueros</i> and other local laws...) and other expenses (city entrance party games, tips to royal officials...). Negotiation, approval and distribution of <i>Cortes</i> economical donation they …
La financiación de las empresas mediterráneas de Alfonso el Magnánimo. Bailía General, Subsidios de Cortes y Crédito Institucional en Valencia (1419-…
2003
This article studies the role of the General Bailía of Valencia—the office for the management of the royal domain resources of the kingdom of Valencia- in the political and military projects of Alfonso V the Magnanimous in the Mediterranean. In this way its also analysed the role of the Parliament, a class representation of the kingdom, and the city of Valencia, main urban centre The incomes from the royal domain, the donations from the Parliaments as a representative assemblies, and the loans provided by the city of Valencia contributed in a decisive way to the guarantee of the economic viability of Alfonso Vs military expansion. It is right that the main instruments that the king had to a…
Nano composite membrane-electrode assembly formation for fuel cell-modeling aspects
2007
Long term stability is an essential requirement for fuel cell applications in automobile and stationary energy systems. In these systems the agglomeration of the catalyst nanoparticles is a well-known phenomenon which cannot be easily overcome or compensated for by re-designing the system. A direct result of this occurrence is the irreversible decrease of the electrochemical performance. Irregularities in electric field distribution are one root cause for migration and subsequent agglomeration of the catalyst nanoparticle. In this work, the impact of the electrode mechanical deformation on electric field distribution was studied using a computer modeling approach. Model of a Proton Exchange…
Las Cortes de 1428 y su repercusión en la Hacienda municipal de la ciudad de Valencia
2004
Call for Cortes council means to Valencia's city big expenses about municipal Treasury. All of them were accounted by <i>clavario</i> of the city in his book of accounts (document wages, copy, donations, etc.). From these books, and also by the same ones written by the <i>Consell</i> (Valencia city council), we can know which expenses they were, and also how, from 1428, mostly percent of these expenses were assumed by <i>Diputation del General</i> (also known as <i>Generalitat</i>, Kingdom political and economic assembly).<br><br>La convocatoria para asistir a Cortes le suponía a la ciudad de Valencia toda una serie de gastos que r…
Data from: Exposing the structure of an Arctic food web
2016
How food webs are structured has major implications for their stability and dynamics. While poorly studied to date, arctic food webs are commonly assumed to be simple in structure, with few links per species. If this is the case, then different parts of the web may be weakly connected to each other, with populations and species united by only a low number of links. We provide the first highly resolved description of trophic link structure for a large part of a high-arctic food web. For this purpose, we apply a combination of recent techniques to describing the links between three predator guilds (insectivorous birds, spiders, and lepidopteran parasitoids) and their two dominant prey orders …

Raman Spectroscopic Signatures of Echovirus 1 Uncoating
2014
ABSTRACT In recent decades, Raman spectroscopy has entered the biological and medical fields. It enables nondestructive analysis of structural details at the molecular level and has been used to study viruses and their constituents. Here, we used Raman spectroscopy to study echovirus 1 (EV1), a small, nonenveloped human pathogen, in two different uncoating states induced by heat treatments. Raman signals of capsid proteins and RNA genome were observed from the intact virus, the uncoating intermediate, and disrupted virions. Transmission electron microscopy data revealed general structural changes between the studied particles. Compared to spectral characteristics of proteins in the intact v…
