Susceptibility of Seven Termite Species (Isoptera) to the Entomopathogenic Fungus Metarhizium anisopliae
2009
International audience; Seven termite species (Isoptera) from five families were tested for disease susceptibility against the entomopathogenic fungus Metarhizium anisopliae using a standard protocol: Mastotermes darwiniensis (Mastotermitidae), Hodotermopsis sjoestedti (termopsidae), Hodotermes mossambicus (Hodotermitidae), Kalotermes flavicollis (Kalotermitidae), Reticulitermes flavipes and Prorhinotermes canalifrons (Rhinotermitidae), and Nasutitermes voeltzkowi (termitidae). Our results showed a large diversity in disease susceptibility against M. anisopliae among the different species tested and we suggest that the evolution of disease resistance mechanisms in Isoptera may be influenced…
Development of a rapid and highly sensitive biochemical method for the measurement of fungal spore viability. An alternative to the CFU method
2001
Abstract 1 A biochemical method, based on dehydrogenase activity (DHA) measurement, has been developed as an alternative to colony forming unit (CFU) enumeration, for assessing the viability of fungal spores. In viable cells, a tetrazolium salt (MTT) is reduced to a coloured formazan (MTTf) by cellular dehydrogenase enzymes. From the colorimetric assay developed by Mosmann for mammalian cells, the procedure has been adapted and optimised using P. digitatum spores as a model. Propan-2-ol has been selected as the best solvent to extract the MTTf from the spores. The sensitivity of the method has been considerably increased by determining the optimal conditions of incubation for the MTT reduct…

One-dimensional heterogeneous solids with uncertain elastic modulus in presence of long-range interactions: Interval versus stochastic analysis
2013
The analysis of one-dimensional non-local elastic solids with uncertain Young's modulus is addressed. Non-local effects are represented as long-range central body forces between non-adjacent volume elements. For comparison purpose, the fluctuating elastic modulus of the material is modeled following both a probabilistic and a non-probabilistic approach. To this aim, a novel definition of the interval field concept, able to limit the overestimation affecting ordinary interval analysis, is introduced. Approximate closed-form expressions are derived for the bounds of the interval displacement field as well as for the mean-value and variance of the stochastic response.

MEDLEM database, a data collection on large Elasmobranchs in the Mediterranean and Black seas
2020
The Mediterranean Large Elasmobranchs Monitoring (MEDLEM) database contains more than 3,000 records (with more than 4,000 individuals) of large elasmobranch species from 21 different countries around the Mediterranean and Black seas, observed from 1666 to 2017. The principal species included in the archive are the devil ray (1,868 individuals), the basking shark (935 individuals), the blue shark (622 individuals), and the great white shark (342 individuals). In the last decades, other species such as the thresher shark (187 individuals), the shortfin mako (180 individuals), and the spiny butterfly ray (138) were reported with increasing frequency. This was possibly due to increased public a…
Profesora Imanuela Bencingera (1865-1935) privātkolekcija Latvijas Universitātes Bibliotēkas krājumā
2016
The private library of Immanuel Benzinger (1865-1935), a professor of theology at the Faculty of Theology of the University of Latvia from 1921 till 1935, is one of remarkable historical collections at the disposal of the Library of the University of Latvia. It comprises literature that reflects all areas of prof. Immanuel Benzinger’s interests and had provided him a high level of competence in the field of theology, covering a broad spectrum of research materials on the Old Testament, biblical archeology and biblical geography, biblical languages and resources for studying them, etc.etc. This historical collection mostly represents books issued at the end of the19th century and the first d…
Seasonal and daily variation in physical activity among three-year-old Finnish preschool children
2013
The purposes of this study were to assess seasonal, daily, and gender variations in children’s physical activity (PA). ActiGraph GT3X accelerometers were used to record the three-year-old children’s PA levels for five consecutive days in autumn and winter. Complete data for both seasons were obtained for 47 children. Despite a significant difference in seasonal temperatures (p < .001), differences were only found for weekdays light PA (p = .021). No difference in PA was observed between weekdays and weekend days. Only 20% of the sample had ≥120 minutes light-to-vigorous PA (LMVPA), and 46% of children had ≥60 minutes moderate-to-vigorous PA (MVPA). Boys spent more minutes in LMVPA (p = .001…
Epistemic governance in local policy debates : The case of entitlement to early childhood education and care in Finland
2019
In Finland, children below school age have enjoyed the right to attend subsidised full-time early childhood education and care (ECEC). However, the attendance rate in Finland is low in comparison to other Nordic countries. Furthermore, the entitlement was restricted to 20 h per week in 2016 unless the child’s parents work or study full-time or unless it is believed that the child will benefit from full-time ECEC. The debates concerning restrictions in ECEC entitlement in three municipal councils serve as the data for this study. By using the framework of epistemic governance, we identify three differing constructions of the ECEC’s societal functions in the municipal policy debates. The simi…
