Different sample treatment approaches for the analysis of T-2 and HT-2 toxins from oats-based media.
2010
A LC-DAD method is proposed for the determination of the T-2 and HT-2 toxins in cultures of Fusarium langsethiae in oat-based and other in vitro media. Test media consisted of freshly prepared milled oats to which T-2 and HT-2 toxin stock solutions were added. Different mixtures of extraction solvent (acetonitrile:water and methanol water), extraction times (30', 60' or 90') and drying methods were investigated. Results showed that extraction with methanol: water (80:20, v/v) for 90 min, drying with N-2 and subsequent analysis by LC-DAD was the fastest and most user friendly method for detecting HT-2 and T-2 toxins production by F. langsethiae strains grown on oat-based media at levels of 0…
Toward learning autonomous pallets by using fuzzy rules, applied in a Conwip system
2012
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-4057-8 Nowadays, material planning and control strategies are becoming continuously complex tasks spanning from individual plants to logistic networks. In fact, this is the consequence of increasing intricacy in product variants and their respective convolution in networks’ structures. Customers ask for specific products with individual characteristics that force companies for more clever performances by more flexibility. For doing so, the existing planning and control systems, which work based on central m…
The radio antipodal and radio numbers of the hypercube
2011
International audience; A radio k-labeling of a connected graph G is an assignment f of non negative integers to the vertices of G such that |f(x) − f(y)| \ge k + 1 − d(x, y), for any two vertices x and y, where d(x, y) is the distance between x and y in G. The radio antipodal number is the minimum span of a radio (diam(G) − 1)-labeling of G and the radio number is the minimum span of a radio (diam(G))-labeling of G. In this paper, the radio antipodal number and the radio number of the hypercube are determined by using a generalization of binary Gray codes.
¿Cabe hablar de una «generación de la crisis»? Discusión en torno a una noción sobreexplotada
2018
This article states that nowadays there is an overuse (or a misuse) of the «Generation» idea. The discussion among many authors over the «Generation of crisis» concept suggests that it is useful to outline the characteristics of the target of population of the collective of youth who are mainly affected by the economic and social crisis over the past years. Nevertheless, through analyzing the meanings of the «Generation of Crisis» made by Mannheim, Ortega and other classic authors, it is clear that the social class approach together with the generational one are needed to define this concrete concept. The conclusion of the articleis that both approaches are seen as underpinning their utilit…
Romanssi, satiiri vai yhteiskunnallinen kannanotto? : Virpi Hämeen-Anttilan Suden vuosi 2000-luvun suomalaisena yliopistoromaanina
2013
Tiivistelmä – Abstract Kaunokirjallinen fiktio perustuu usein todelliseen maailmaan ja todellisiin ihmisiin. Lukijat etsivät kirjallisuudesta kiinnekohtaa todellisuuteen ja käyttävät kirjallisuutta oman maailmankuvansa hahmottamiseen, tavalla tai toisella. Lukija myös usein olettaa, että kaunokirjallisuudesta saatu kuva vastaa todellisuutta. Lukija muodostaa tulkintansa hyödyntäen omaa eri lähteistä saatua kompetenssiaan, käyttäen esimerkiksi lajitietouttaan luokittelemalla tekstin tiettyyn lajiin kuuluvaksi. Tämän tutkielman lähtökohtana oli tarkastella yliopistoyhteisön ilmenemistä kaunokirjallisuudessa, nimenomaan suomalaisissa romaaneissa ja suomalaisessa kontekstissa. Kyseistä ilmiötä …
Nuevos caminos, territorio y paisaje en la Comarca de la Costera (Valencia). La mirada de los viajeros
2019
Por sus condiciones físicas, el valle de la Costera ha sido históricamente un lugar de paso obligado en el itinerario que, desde la llanura litoral valenciana, se dirige al sur y al centro peninsular. A finales del siglo XVIII se construye una moderna carretera y a mediados del XIX entra en servicio el ferrocarril entre Madrid y Valencia. En este trabajo analizamos la relación que se establece entre los caminos y el paisaje, y cómo esta se ha reflejado en los escritos que los viajeros que, entre finales del siglo XVIII y a lo largo de todo el siglo XIX, recorrieron por carretera y ferrocarril el valle de la Costera. Sus relatos integran estas modernas obras públicas con la visión secuencial…
Use of algae in active biomonitoring of Surface waters
2014
Przeprowadzono badania biomonitoringowe trzech zbiorników retencyjnych położonych na terenie województwa opolskiego (południowa Polska): Zbiornika Turawa, Zbiornika Nysa i Zbiornika Otmuchów. W glonach słodkowodnych Spirogyra sp. i morskich Palmaria palmata (Linnaeus) Weber & Mohr, eksponowanych w badanych wodach, oznaczono metodą absorpcyjnej spektrometrii atomowej (AAS) przyrosty stężeń: Mn, Fe, Cu, Zn, Cd i Pb. W wodach oznaczano także pH, konduktywność oraz stężenie Mn i Fe. Stężenia Cu, Zn, Cd i Pb w badanych wodach były mniejsze od granicy oznaczalności metody. Badania prowadzono od czerwca do lipca 2014 r. Wskazano na różnice w przyrostach stężeń metali ciężkich w próbkach glonów eks…

About Vertex Mappings
2019
Summary In [6] partial graph mappings were formalized in the Mizar system [3]. Such mappings map some vertices and edges of a graph to another while preserving adjacency. While this general approach is appropriate for the general form of (multidi)graphs as introduced in [7], a more specialized version for graphs without parallel edges seems convenient. As such, partial vertex mappings preserving adjacency between the mapped verticed are formalized here.
Using 2-colorings in the theory of uniquely Hamiltonian graphs

We use the concept of 2-coloring in analyzing UH3 graphs and building exact specifications of functions to find new UH3 graphs by Hamiltonian cycle edge extractions
