Hemoprotozoa of domestic animals in France: Prevalence and molecular characterization
2008
Very limited information is available on epizootiology of haematozoan infections in French domestic animals. In an attempt to address this issue, prevalence of piroplasmida was studied in carnivores and ruminants, whereas prevalence of Hepatozoon spp. was only investigated in carnivores. In total, 383 animals were included in the survey (namely 116 cats, 108 dogs, 91 sheep and 68 cows). Parasite diagnosis was carried out using molecular methods such as PCR and sequencing of the 18S rRNA gene. In addition, ruminant samples were analyzed with the reverse line blotting technique (RLB). Results of RLB and PCR plus sequencing were in total agreement. In carnivores, haematozoan prevalence was clo…
New Sperm Morphology Analysis in Equids : Trumorph ® Vs Eosin-Nigrosin Stain
2021
Equine Reproduction Service. Department of Animal Medicine and Surgery. Veterinary Faculty. Autonomous University of Barcelona. National Agency for Research and Development (ANID), Ministry of Education, Chile (2017/72180128). Secretary of Higher Education, Science, Technology and Innovation (SENESCYT)(CZ02-000507-2019) The evaluation of the male fertility potential is based on the analysis of the basic spermatic characteristics of concentration, motility and morphology. Thus, the study of sperm morphology is a fundamental element in the seminal analysis, but its real meaning has been biased by the techniques used for its evaluation. These techniques involve dehydration phases and subsequen…
Data quality of 5 years of central norovirus outbreak reporting in the European Network for food-borne viruses
2008
ABSTRACT Background The food-borne viruses in Europe (FBVE) network database was established in 1999 to monitor trends in outbreaks of gastroenteritisdue to noroviruses (NoVs), to identify major transmission routes of NoV infections within and between participating countries and to detectdiffuse international food-borne outbreaks.Methods We reviewed the total of 9430 NoVoutbreak reports from 13 countries with date of onset between 1 January 2002 and 1 January2007 for representativeness, completeness and timeliness against these objectives.Results Rates of reporting ranged from a yearly average of 1.8 in 2003 to 11.6 in 2006. Completeness of reporting of an agreed minimumdataset improved ove…
La pintura de flores de Miguel Parra (1780-1846)
2013
Although Miguel Parra Abril (Valencia, 1780-Madrid, 1846) is one of the most important Valencian School painters of floral still lifes, this aspect of his work remains little known. The present article addresses this oversight in two ways. First, by offering an overview of his oeuvre as a painter of floral subjects from his student days at the Fine Arts Academy of Valencia through his mature works. Second, by analyzing two heretofore-unpublished floral compositions in relation to his more familiar works, particularly those located in private collections until recent years.Aunque Miguel Parra Abril (Valencia, 1780-Madrid, 1846) es uno de los pintores de flores más importantes de la Escuela v…
LA PLACE DU CULINAIRE DANS LE MONDE DE L’ÉCRIT : ENTRE EXCELLENCE ET HUMANISME
2016
International audience; Profitant d'une sorte d'incarnation à la loi du plaisir, le fait culinaire se représente aux consommateurs comme un heureux manuscrit ou ebook aux images pieusement alléchantes, et propose une modélisation et normalisation d'influence pour le commun des mortels. Les vertiges de l'édition culinaire Face à l'épidémie des livres 1 de pratique culinaire, que l'on peut sans aucune mesure différencier des ouvrages de culture gastronomique, et compte tenu du grand nombre édité chaque année, faire l'exercice d'un éventuel résumé du sujet pourrait être une périlleuse tentative. En fonction de l'angle de vue disciplinaire, on prendrait le risque de passer à côté de l'essentiel…
The bridge volcanic LIdar-BILLI: A review of data collection and processing techniques in the Italian most hazardous volcanic areas
2020
Volcanologists have demonstrated that carbon dioxide (CO2) fluxes are precursors of volcanic eruptions. Controlling volcanic gases and, in particular, the CO2 flux, is technically challenging, but we can retrieve useful information from magmatic/geological process studies for the mitigation of volcanic hazards including air traffic security. Existing techniques used to probe volcanic gas fluxes have severe limitations such as the requirement of near-vent in situ measurements, which is unsafe for operators and deleterious for equipment. In order to overcome these limitations, a novel range-resolved DIAL-Lidar (Differential Absorption Light Detection and Ranging) has been developed as part of…

There are given two examples, that illustrates the challenges library have faced regarding the process of creating exhibitions.
Municipal Solid Waste Management in the Accra Metropolitan Area, Ghana
2003
Municipal solid waste management in Accra, Ghana, is at present delivered in an unsustainable manner. Due to uncontrolled urbanisation, large quantities of waste are generated daily in Accra, and this exerts much pressure on an over strained solid waste management system. Coupled with weak institutional capacity, and lack of resources, both human and capital, the city authorities face difficulties in ensuring that all the waste generated in the city is collected for disposal. Home collection of waste is limited to high and, some middle income areas while the poor are left to contend with the problem on their own. This leads to indiscriminate disposal of waste in surface drains, canals and s…
Groundwater radon measurements in the Mt. Etna area.
2003
Radon levels were measured in 119 groundwater samples collected throughout the active volcanic area of Mt. Etna by means of a portable Lucas-type scintillation chamber. The measured activity values range from 1.8 to 52.7 Bq l(-1). About 40% of the samples exceed the maximum contaminant level of 11 Bq l(-1) proposed by the USEPA in 1991. The highest radon levels are measured in the eastern sector of the volcano, which is the seismically most active zone of the volcano. On the contrary the south-western sector, which is both seismically active and a site of intense magmatic degassing, display lower radon levels. This is probably due to the formation of a free gas phase (oversaturation of CO(2…
The ELECTRE I method to optimise GPR data processing analyses for maintenance of water networks
2017
Management of water supply systems (WSSs) can be effectively pursued by means of data processing techniques based on Ground Penetrating Radar (GPR) image mining. This approach enables to collect different graphical representations of WSS buried elements on the basis of which planning maintenance interventions, with the objective of improving the overall condition of the system. This paper proposes to support this kind of techniques by means of a multi criteria decision making (MCDM) point of view. In particular, the ELECTRE I method is suggested to treat results coming from the application of different techniques. A real case study is applied with relation to a set of four alternatives, whi…
