Multilingual dictionary of tourism = Diccionario multilingüe de turismo
2014
Este recurso lexicográfico ha sido elaborado por el Grupo de investigación COMETVAL (Corpus Multilingüe de Turismo de la Universitat de València) http://www.uv.es/cometval/wikibase/cas/index.wiki). COMETVAL se crea en 2009 y desde entonces ha contado con ayudas de diversos organismos (Universitat de València, la Agencia Valenciana de Turismo y, en la actualidad, el Ministerio de Economía y Competitividad). Pertenecen a dicho grupo un importante número de investigadores de diferentes departamentos y universidades españolas (Universitat de València, Universitat Politècnica de València, Universidad Católica de Valencia San Vicente Mártir, Universitat Jaume I de Castellón y Universidad de Almer…
Senatus consultum ‚ultimum‘ und Erklärung zum Staatsfeind zwischen Recht, Rhetorik und Politik im spätrepublikanischen Rom
2020
Sulla base di un riesame delle fonti che danno notizie sull'ultima età repubblicana - considerata una fase di crisi - il senatus consultum cd. ultimum e la dichiarazione di nemico della patria (hostis rei publicae) vengono rilette in rapporto fra loro con particolare attenzione alle intersezioni che i due istituti presentano sul piano strettamente giuridico, su quello retorico e su quello politico. L'analisi così condotta consente così di scorgere proprio nell'ultima fase della libera res publica i precedenti storici del ricorso all'idea dello 'stato di necessità' come strumento volto a giustificare il sacrificio dei diritti fondamentali dei cittadini e apre una nuova prospettiva di ricerca…
CoproID predicts the source of coprolites and paleofeces using microbiome composition and host DNA content
2020
Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical distortions in archaeological sediments, making their source species difficult to identify on the basis of fecal morphology or microscopic features alone. Here we present a reproducible and scalable pipeline using both host and microbial DNA to infer the host source of fecal material. We apply this pipeline to newly sequenced archaeological specimens and show that we are able to distinguish morphologically similar human and canine paleofeces, as well as non-fecal sediments, fro…
A case report of double etiology of ecthyma gangrenosum
2019
Abstract Rationale: Ecthyma gangrenosum is a cutaneous infection, most commonly occurring during sepsis evolution with Pseudomonas aeruginosa on an immunocompromised background. There have been rare case reports in previously healthy children and rarer are the cases with double etiology. Patient concerns: We present the case of a female Caucasian patient, aged 1 year and 8 months, who developed severe sepsis during flu evolution with predominant respiratory and cerebral manifestations. On admission, at skin level, there was noticed a necrotic coccygeal ulceration (with rapid increasing dimensions 0.5/0.5 cm in 24 hours), and with the transformation from a dry necrosis in a sphacelus at the …
Tourism-related informal interaction in Chembe, Malawi : an ethnographic study
2016
Tutkielmassa tarkastellaan turismin liittyvää vapaamuotoista kanssakäymistä paikallisten malawilaisten sekä ulkomaalaisten asukkaiden ja matkailijoiden välillä. Etnografinen pääaineisto on kerätty Malawissa keväällä 2013 ja se koostuu haastatteluista ja muistiinpanoista. Tosisijainen aineisto koostuu raporteista ja asiakirjoista, joiden tarkoitus on hahmotella ruohonjuuritason vuorovaikutukselle laajempi yhteiskunnallinen konteksti. Metodologisesti tutkielma hyödyntää ranskalaisen sosiologin ja etnologin Pierre Bourdieun esittelemää käytännön teoriaa ja sen keskeisiäkäsitteitä, jotka ovat kenttä, pääoma ja habitus. Tutkielman tarkoitus on valottaa niitä tekijöitä, jotka määrittävät eri toim…
The natural history of Echinorhynchus bothniensis Zdzitowiecki and Valtonen, 1987 (Acanthocephala) in a high Arctic lake.
2015
The acanthocephalan Echinorhynchus bothniensis Zdzitowiecki and Valtonen, 1987 differs from most other species in the genus Echinorhynchus Zoega in Muller, 1776 by infecting mysids (order Mysida) instead of amphipods (order Amphipoda) as intermediate hosts. Here we report on the occurrence of E. bothniensis in mysids (Mysis segerstralei Audzijonytė et Vainola) and in its fish definitive hosts in a high Arctic lake. Out of 15 907 sampled mysids, 4.8% were infected with a mean intensity of 1.05 worms (range 1-5), although there was notable variation between samples taken in different years and sites. Larger mysids appear more likely to be infected. Of five fish species sampled, charr,Salvelin…
Segregation and co-occurrence of larval cestodes in freshwater fishes in the Bothnian Bay, Finland
1992
SUMMARYTwo autogenic (Triaenophorus crassus and T. nodulosus) and four allogenic (Diphyllobothrium latum, D. dendriticum, D. ditremum and Schistocephalus solidus) larval cestode species were found in 13 out of 31 fish species studied from the Bothnian Bay, NE Baltic. Gasterosteus aculeatus was the most heavily infected fish with 4 larval cestode species; for two of them (D. ditremum and S. solidus) the three-spined stickleback was found to be the required fish intermediate host. Among allogenic cestode species, those restricted to different definitive host species segregated their larval population in relation to the fish host, while, for example, D. ditremum and S. solidus, both maturing i…
The impact of variable hatching rates on parasite control: a model of an aquatic ectoparasite in a Finnish fish farm
2006
Summary 1 Many parasites of medical and veterinary importance infect via free-living stages that undergo a period of development in the environment before seeking a host. Frequently, considerable variation is observed in the development rates of these stages, such that some individuals may be considered to occupy distinct subpopulations, similar to a plant's seed bank. Under certain conditions, these subpopulations may act as a reservoir for the parasite, buffering it from the impact of management strategies and reducing control success. 2 We assessed the impact of intraspecific variation in development rates on parasite control by developing a population dynamic model of the ectoparasite A…
Phenotypic tradeoffs between egg number and egg size in three parasitic anisakid nematodes
2007
Phenotypic tradeoffs between number and size of eggs were tested in three component populations of three marine anisakid nematodes: Anisakis simplex, Pseudoterranova decipiens and Contracaecum osculatum. Body and uterine volumes (as proxies of female size), and egg number, mean egg volume and clutch volume (as descriptors of reproductive output) were measured in 50 females of each species. Evidence of a phenotypic tradeoff was detected only in A. simplex; the first time that has been found in a parasite population. Comparison of feasible values inferred from the van Noordwijk and de Jong's model and current data showed that interindividual variation in egg size was narrower than expected in…
