An accurate one-diode model suited to represent the current-voltage characteristics of crystalline and thin-film photovoltaic modules
2020
Abstract In this paper a new one-diode model, conceived in order to be used to represent the current-voltage curves of both crystalline and thin-film photovoltaic modules, is presented. The model parameters are calculated from the information contained in the datasheets issued by manufactures by means of simple iterative procedures that do not require the assumption of simplifying hypotheses. Some innovative relations describing the dependence of the parameters from the solar irradiance and cell temperature are adopted in order to permit the model to reliably simulate the electrical behaviour of photovoltaic devices operating in real conditions. The ability of the model to calculate the cur…

The building of the Zisa, commissioned by William I, began in 1164-1165; it was completed by William II in the years immediately following. It was built as a splendid place for rest and amusement, ...
"Un puente sobre el abismo", de Higinio Noja Ruiz (1932) : cultura libertaria y literatura pacifista de entreguerras
2021
El escritor, ensayista y militante anarquista Higinio Noja Ruiz publicó en 1932 la novela Un puente sobre el abismo en la Editorial Estudios de Valencia. En ella Noja abordó el tema de las guerras y la lucha contra ellas a través de su protagonista, Guillermo Arjona, un joven burgués mallorquín muy influido por su lectura de las novelas sobre la Primera Guerra Mundial y casi obsesionado con esta temática. Se analiza aquí en primer lugar la figura de Noja Ruiz (1994-1972), prolífico novelista social a la vez que ensayista y pensador libertario de las décadas de 1920 y 1930. La trayectoria de Noja es inseparable de la de la revista cultural y editorial libertaria valenciana Estudios (1928-193…
Ideas and lives across the Atlantic. The American Anarchism in the Galician libertarian press
2019
In this article we will analyse, from a transnational history point of view, the presence of American anarchism in the Galician libertarian press until 1936. In the 19th and 20h centuries, the transatlantic migrations contributed to develop a dense network of contacts and relationships between Galicia and American countries. This network involves anarchist militants on both sides of the Ocean. The Galician anarchists have a close collaboration with her Americans libertarian comrades; and many Galician militants are actively committed in the labour movement of their host countries. The Galician libertarian press shows this relationship and this participation in different ways (articles, cont…
Nuevos datos sobre el uso de materia colorante durante el Neolítico antiguo en las comarcas centrales valencianas
2006
La caracterización mineralógica de materias colorantes procedentes de los yacimientos valencianos de la Cova de l'Or, la Cova de la Sarna y la Cova Fosca de la Vall d'Ebo demuestra el uso de dos tipos de materia colorante durante el Neolítico Antiguo: Hematites y Cinabrio. Las características y distribución geográfica de cada una de ellas nos remiten a dos estrategias distintas de obtención y. probablemente. de utilización de las mismas.
Ritual Experts and Participants in the Ancient Near East and the Hebrew Bible
2020
AbstractThe chapter summarizes the roles and tasks of ritual experts and participants within the Hebrew Bible and its cultural environment. The first part reflects on the responsibilities of the kings, the priests, and the priestesses within the ancient Near East (Mesopotamia, Mari, Hittite Anatolia) and ancient Egypt. Then the chapter turns to the concepts of the Hebrew Bible. The second part demonstrates how the priests and Levites take care for the rituals, the sacrifices, purity, teaching, and administration. Cult prophets and the king have their limited and special functions. Third, at certain points lay people may participate in the cult: the offering person, women, children, and the …
Andrea e gli argentieri Memingher in Sicilia
2018
Andrea Memingher è una tra le più enigmatiche figure di argentieri attivi a Palermo nella seconda metà del XVII secolo. Si può ritenere che la famiglia avesse origini nordiche e che, dopo un passaggio a Napoli, si stabilisse definitivamente a Palermo, inserendosi nella maestranza degli orafi e argentieri della città, probabilmente grazie ad un matrimonio con una figlia o una sorella o una vedova di un membro palermitano della maestranza. La presenza di Paolo Memingher nel capoluogo siciliano è attestata già nel 1660, due anni prima della data di inizio della sua attività, protrattasi fino al 1678. Il più importante esponente della famiglia fu Andrea, figlio di Paolo, il quale dovette la sua…

The Stern-Gerlach experiment revisited
2016
The Stern-Gerlach-Experiment (SGE) of 1922 is a seminal benchmark experiment of quantum physics providing evidence for several fundamental properties of quantum systems. Based on today's knowledge we illustrate the different benchmark results of the SGE for the development of modern quantum physics and chemistry. The SGE provided the first direct experimental evidence for angular momentum quantization in the quantum world and thus also for the existence of directional quantization of all angular momenta in the process of measurement. It measured for the first time a ground state property of an atom, it produced for the first time a `spin-polarized' atomic beam, it almost revealed the electr…
