Data from: Ecological impact assessments of alien species in Norway
2020
Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in local biodiversity and ecosystem functioning, and, ultimately, to biotic homogenisation. We risk-assessed all alien plants, animals, fungi and algae, within certain delimitations, that are known to reproduce in Norway. Mainland Norway and the Arctic archipelago of Svalbard plus Jan Mayen were treated as separate assessment areas. Assessments followed the Generic Ecological Impact Assessment of Alien Species (GEIAA) protocol, which uses a fully quantitative set of criteria. A tot…
Quantification and viability assays of Toxoplasma gondii in commercial "Serrano" ham samples using magnetic capture real-time qPCR and bioassay techn…
2014
"Serrano" ham is a typical pork product from the Mediterranean area, highly valued for its flavour. To make Serrano ham, pork undergoes a salting and a subsequent fermentation process known as curing. Certain pigs used for meat production are an important source of Toxoplasma gondii infection in humans. We have developed a method for quantifying and assaying the viability of the T. gondii present in commercial Serrano ham samples. A magnetic capture method for the isolation of T. gondii DNA and a qRT-PCR were used to estimate the T. gondii burden in 475 commercial samples of "Serrano" ham in two presentation formats: ham pieces and sliced ham. The infectivity capacity of T. gondii in positi…

The PREDIMED-Plus trial was supported by the European Research Council (Advanced Research grant 2014–2019; agreement #340918; granted to M.Á.M.-G.); the official Spanish institutions for funding scientific biomedical research, CIBER Fisiopatología de la Obesidad y Nutrición (CIBEROBN) and Instituto de Salud Carlos III (ISCIII) through the Fondo de Investigación para la Salud (FIS) which is co-funded by the European Regional Development Fund (coordinated FIS projects led by J.S-S. and J.V., including the following projects: PI13/00673, PI13/00492, PI13/00272, PI13/01123, PI13/00462, PI13/00233, PI13/02184, PI13/00728, PI13/01090, PI13/01056, PI14/01722, PI14/00636, PI14/00618, PI14/00696, PI…
A new tool to create on-line examinations. Integration into Aula Virtual.
2009
Actualmente, la Universitat de València utiliza un Sistema de Gestión del Aprendizaje (en ingles Learning Management System LMS), como apoyo al proceso de enseñanza-aprendizaje. Este LMS incluye una herramienta que permite a los profesores crear exámenes online. Sin embargo, la interfaz de usuario que provee la plataforma no presenta un entorno amigable. Para mejorar la usabilidad del modulo, hemos desarrollado un programa informático que simplifica el proceso. Partiendo de un programa open source denominado QAED, desarrollado en la Universitat Pompeu Fabra, lo hemos extendido para permitir a los profesores crear exámenes offline. Después, pueden importarse fácilmente al Aula Virtual.
Debonding failure mechanisms in prestressed CFRP/epoxy/concrete connections
2014
Abstract This paper presents an investigation on the failure mode in prestress force-release tests of CFRP strips bonded to concrete substrates. Background of the study is the gradient anchorage technique. Firstly, experimental test series are presented. It is shown that considerable differences in failure mechanisms between lap-shear and the before mentioned release tests exist. The study reveals a strong Mode I-influence in the debonding process, compared to a Mode II for lap-shear tests. Secondly, FE simulations with a commercially available software are introduced. It is demonstrated that delamination in a force-release test occurs by a mixed-mode failure over the strip width.
Coloristic and antimicrobial behaviour of polymeric substrates using bioactive substances
2016
A major concern in reducing microbial contamination of healthcare and hygiene products motivated us to seek viable alternatives in order to create such barriers. The antimicrobial and anti-oxidant effects of natural extracts are well-known, their application onto polymeric supports is still challenging in terms of investigation. To our knowledge, the method of natural dyeing of different polymeric substrates using bioactive substances derived from black currant and green walnut shells, in conjunction with biomordants, and their long term effects have not been very consistently reported. The main objective of the study is based on the comparative study of different polymeric fibrous substrat…
Experimental Evaluation of a New Thermal Process for Microorganisms Inactivation
2015
A new thermal process for the inactivation of microorganisms in beverages has been studied and is presented in this paper. The treatment, not yet studied in the scientific literature, mainly consists of a thermal shock characterized by temperature increases up to 30°C/s, with final temperatures up to 65°C. This study presents the first experimental results obtained by the application of the new thermal treatment, with different combinations of the process parameters (rate of temperature rise, final temperature and holding time), on separate suspensions of Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Listeria innocua and Candida albicans. The required rapid temperature in…
Lung Ultrasonography – A Paraclinical Investigation Promoter in Community-Acquired Pneumonia Diagnosis in Children
2019
Abstract Lung ultrasonography is an excellent alternative to chest radiography, with better sensitivity, specificity, positive and negative predictive values and, finally, with better accuracy. The lung ultrasonography is proven to be useful in trying to reduce the request of chest radiography. In the opinion of most specialists, lung ultrasonography is recommended to be a valuable tool for the diagnosis of community-acquired pneumonia in children. Considering the fact that clinical examination remains essential because it suspects the diagnosis, the evolution does not require radiologic follow-up, also the pathologic findings at the clinical examination may change over the course of a day,…
Histophotometry: a new method for automated histological examination of solid tissue samples demonstrated on bladder cancer.
1979
The purpose of this study was to demonstrate the ability of a new method to discriminate between benign and malignant tissue. Tissue samples from three patients with bladder tumours and one patient with bladder diverticula have been examined by histophotometry. This method, based on the correlation of nuclear volume and nucleic acid contents per cell uses thick formalin fixed samples. The results are obtained by measurements averaging more than one hundred thousand cells per sample. By this histophotometric examination a clear differentiation between malignant and benign tissue could be achieved. It was also possible to determine the degree of malignancy and to differentiate between infiltr…
Profiling of compounds and degradation products from the postharvest treatment of pears and apples by ultra-high pressure liquid chromatography quadr…
2010
This study deals with a simple strategy to pinpoint potential unknown compounds in full scan mass spectrometry (MS) experiments. Forty samples of apples and pears intended for human consumption were analyzed by ultra-high performance liquid chromatography quadrupole-time-of-flight (UPLC–QqTOF-MS), after extraction of the possible contaminants by rinsing the peel of the fruit with ethyl acetate. The peaks were visually recognized in the total ion chromatogram (TIC). Two major types of postharvest treatments were detected in this set of samples: imazalil (IMZ)/ethoxyquin (EQ) and thiabendazole (TBZ)/diphenylamine (DPA). The present work also describes the metabolites formed by degradation of …
