Les micromammifères du département de l'Isère (Rhône-Alpes, France) : répartition par district naturel.

2013

Micromammals of the French department of Isère (Rhône-Alpes) : distribution by natural district. - This article presents the distribution of the species of micromammals of the department of Isère (Rhône-Alpes, France), by natural district from the analysis of 78,100 specimens inventoried and registered in a database of the micromammals of the department. For each species, a comparison of its distribution is made between districts. This synthesis is a photograph of the current knowledge and it also allows to define the future researches to improve the knowledge and the protection of micromammals in Isère.

El litigio climático ante la responsabilidad intergeneracional

2021

El carácter intergeneracional del litigio climático plantea un interés sobre la protección jurídica de las generaciones futuras. La preocupación intergeneracional no es novedosa en el Derecho, sin embargo, debido al ascendiente número de litigios climáticos presentados por jóvenes en nombre propio y en el de las generaciones futuras para demandar mayor ambición climática han incorporado nuevas formas de observar este fenómeno. En esta contribución se lleva a cabo un estudio sobre sus implicaciones, la relevancia que puede tener el reconocimiento en normas internacionales e internas de los vínculos intergeneracionales, y cómo, a través del litigio climático, es posible vislumbrar nuevas form…

Air-kerma evaluation at the maze entrance of HDR brachytherapy facilities.

2014

In the absence of procedures for evaluating the design of brachytherapy (BT) facilities for radiation protection purposes, the methodology used for external beam radiotherapy facilities is often adapted. The purpose of this study is to adapt the NCRP 151 methodology for estimating the air-kerma rate at the door in BT facilities. Such methodology was checked against Monte Carlo (MC) techniques using the code Geant4. Five different facility designs were studied for (192)Ir and (60)Co HDR applications to account for several different bunker layouts.For the estimation of the lead thickness needed at the door, the use of transmission data for the real spectra at the door instead of the ones emit…

Compositional and morphological analyses of wax in northern wild berry species.

2019

Accepted manuscript version, licensed CC BY-NC-ND 4.0. Aerial surfaces of plants are covered by a waxy cuticle protecting plants from excessive water loss and UV light. In the present study, composition and morphology of cuticular waxes of northern wild berry species bilberry (Vaccinium myrtillus L.), lingonberry (V. vitis-idaea L.), bog bilberry (V. uliginosum L.) and crowberry (Empetrum nigrum L.) were investigated. Scanning electron microscopy (SEM) revealed differences in epicuticular wax morphology, and gas chromatography–mass spectrometry (GC–MS) analysis confirmed variation in chemical composition of cuticular waxes between the berry species. The dominant compounds in bilberry and li…

Under my wing: lesser kestrels and jackdaws derive reciprocal benefits in mixed-species colonies

2011

In mixed-species assemblages, antipredator benefits for a timid species nesting close to a more pugnacious one are often reported. Advantages for the protected species are usually manifested in terms of higher reproductive success than conspecifics nesting remote to the protector species. Whether the protector species also accrues any benefit remains untested, and the species-specific behavioral traits underlying enhanced reproductive output in mixed-species associations remain poorly documented. We studied associations between lesser kestrels (Falco naumanni) and jackdaws (Corvus monedula) nesting in rural buildings in the Gela Plain (Italy). We tested for interspecific interactions of jac…

Nanostructures materials for protection and consolidation of ancient structures

2014

The preservation and appreciation of the built cultural heritage is of particular interest, through researches and studies on innovative technologies. As evidenced by the good results obtained in some interventions both at national and international level, activities for the conservation of cultural heritage must be the result of synergies and collaboration of interdisciplinary groups, science and knowledge: architecture, engineering, technology, sociology, economics, urban planning, legislation must be managed and planned to work together. The theme of protection and consolidation of ancient structures, applying non-traditional technologies, requires a comprehensive overview of strategies …

Project report : Methodology for terminology harmonisation

2020

A common understanding of language and concepts used is essential for any meaningful communication. For large rescue operations effective communication is crucial to save lives. Such operations can require cooperation among first responders from several sectors with a different understanding of terms and concepts. Redningshåndboka (the National Rescue handbook) provides a common glossary for use across all sectors for their communications in training and practice. However, today each sector maintains their own glossaries, acronyms and jargon, causing potential misunderstandings in joint operations. In this report we propose a way to apply the Norwegian Public Management Standard from the No…

Visitor Regulations vs Rules for visiting Morizsala

1913

Regulations issued by the Riga Society of Naturalists (Naturforscher-Verein zu Rīga; 1845 – 1939) for visitors to Moricsala. The rules were created by approving the first nature protected area in Latvia. The material is stored in the Botany and Mycology collections of the Museum of the University of Latvia.

Biologically based models of cancer risk in radiation research

2020

PURPOSE: In radiation risk analysis the state-of-the-art approach is based on descriptive models which link excess rates of cancer incidence and mortality to radiation exposure by statistical association. To estimate the number of sporadic and radiation-induced cases descriptive models apply parametric dose response function which directly determine the radiation risk. In biologically-based models of cancer risk (BBCR models) dose responses are implemented for key events on the biological level such as early mutations or clonal expansion of initiated cells. Influenced by radiation these events then shape the risk response on the epidemiological level. Although BBCR models facilitate a more …
