Denitrifying microbial communities along a boreal stream with varying land-use
2019
Streams have an important role in regulating nitrogen (N) transportation from terrestrial ecosystems to downstream waters. Here, we examined how catchment land-use affects potential denitrification rates and the function and composition of denitrifier communities in boreal stream sediments, using stable isotope incubations and qPCR and 454-pyrosequencing targeted on nirS, nirK and nosZ genes. Although land-use influenced the water chemistry as higher nitrite + nitrate (NO x − ) concentration at the agriculture-affected sampling point, sediment organic matter content was found to be the key factor in regulating potential denitrification rates. However, the abundance as well as the diversity …
Microbial Community Response on Wastewater Discharge in Boreal Lake Sediments
2017
Despite high performance, municipal wastewater treatment plants (WWTPs) still discharge significant amounts of organic material and nitrogen and even microbes into the receiving water bodies, altering physico-chemical conditions and microbial functions. In this study, we examined how nitrified wastewater affects the microbiology of boreal lake sediments. Microbial community compositions were assessed with next generation sequencing of the 16S rRNA gene, and a more detailed view on nitrogen transformation processes was gained with qPCR targeting on functional genes (nirS, nirK, nosZI, nosZII, amoAarchaea, and amoAbacteria). In both of the two studied lake sites, the microbial community compo…
The occurrence of Echinorhynchus salmonis Müller, 1784 in benthic amphipods in the Baltic Sea
2015
The acanthocephalan Echinorhynchus salmonis Muller, 1784 is a common parasite of salmonid fish, but it has rarely been reported from an intermediate host. Samples of benthic amphipods, Monoporeia affinis (Lindstrom), were taken from multiple, deep sites (usually below 70 m) in the Gulf of Bothnia over the course of more than a decade and examined for acanthocephalans. Overall, only 0.44% of 23 296 amphipods were infected, all with just a single worm. This prevalence is consistent with several previous reports of acanthocephalans in deep-water, benthic amphipods, but it appears low compared to that often reported for acanthocephalan species infecting littoral amphipods. Parasite occurrence d…
Dialogue as a Response to the Psychiatrization of Society? Potentials of the Open Dialogue Approach
2021
In recent decades, the use of psychosocial and psychiatric care systems has increased worldwide. A recent article proposed the concept of psychiatrization as an explanatory framework, describing multiple processes responsible for the spread of psychiatric concepts and forms of treatment. This article aims to explore the potentials of the Open Dialogue (OD) approach for engaging in less psychiatrizing forms of psychosocial support. While OD may not be an all-encompassing solution to de-psychiatrization, this paper refers to previous research showing that OD has the potential to 1) limit the use of neuroleptics, 2), reduce the incidences of mental health problems and 3) decrease the use of ps…
Por sus obras los conoceréis. Documentos de perpetrador y voces de víctimas en Retratos de identificação (Anita Leandro, 2014)
2021
espanolEn los ultimos anos, el estudio de los perpetradores de violencia de masas ha crecido sustancialmente en publicaciones academicas, museos, memorias y cobertura mediatica. Lo ha hecho cada vez con menos dependencia respecto a los influyentes y muy avanzados Holocaust Studies. Ademas, los horizontes de la investigacion se han ampliado desde las personalidades y la maquinaria de destruccion al estudio mas cercano de los documentos, objetos y mirada de los perpetradores. Es en este dominio donde se inscribe un film como Retratos de identificacao de Anita Leandro (2014), film que, nacido de la investigacion historica, se propone reescribir mediante el uso de la composicion y el montaje lo…
Contributo allo studio delle modifiche “indirette” al processo del lavoro introdotte con il D.Lgs. n. 149/2022
2023
L’Autore esamina alcune delle modifiche al codice di procedura civile introdotte con il D.Lgs. n. 149/2022, interrogandosi circa la loro applicabilità al processo del lavoro. Si tratta, in particolare: delle ordinanze ex artt. 183 ter e quater c.p.c.; del procedimento “semplificato” ex artt. 281 decies e ss., c.p.c.; delle udienze mediante collegamenti audiovisivi e del deposito di note scritte in sostituzione dell’udienza (artt. 127-127 ter c.p.c.); del rinvio pregiudiziale in Cassazione ex art. 363 bis c.p.c. The Author examines some of the amendments to the Code of Civil Procedure introduced with Legislative Decree no. 149/2022 and their applicability to the labor process. These are, in …
Las estrategias del comercio especializado
2006
Este trabajo presenta una revisión y actualización de las estrategias empleadas por los minoristas especializados en su lucha competitiva con los minoristas generalistas. En un primer apartado se delimita el concepto de especialista, según la literatura académica, para pasar después a cuantificar su situación en España, en Europa y en Estados Unidos. A continuación se analiza la posición de los especialistas en los diferentes subsectores de actividad, para finalizar con una propuesta de las estrategias llevadas a cabo por los especialistas en España. This paper contains a review and update of the strategies used by specialized retailers to compete with their general counterparts. After defi…
A mate to die for? A model of conditional monogyny in cannibalistic spiders.
2012
Monogynous males in various species actively limit themselves to mating with a single female in their lifetime. Whereas previous models have considered monogyny as an obligate mating strategy, here we explore the potential of monogyny to evolve as a context-specific (conditional) behavior. Using a state-dependent dynamic game model based on the biology of the cannibalistic spider Argiope bruennichi, we confirm that conditional monogyny can evolve under broad conditions, including an even sex ratio. We predict that males should make a terminal investment when mating with large, virgin females, especially if population density is low and the encounter occurs late in the season. We encourage e…
De l'embauche à la démission ou les écueils du travail associatif dans les associations locales de solidarité internationale
2010
A partir d’une pré-enquête réalisée dans deux associations de solidarité internationale impliquée dans le commerce équitable et partant du constat que le turn-over des salariés y est important, nous avons cherché à comprendre pourquoi, après quelques mois, les nouvelles recrues décident de mettre prématurément un terme à leur activité. Nous nous sommes intéressé à la fois aux organisations, aux salariés mais aussi aux bénévoles présents dans ces collectifs afin d’appréhender l’ensemble des interactions qui s’y produisent pour mieux saisir les facteurs et contraintes à la fois structurelles, individuelles ou relationnelles. On montre que, bien souvent, l’associatif est envisagé comme un lieu…
Earth resistance measurements in urban contexts: Problems and possible solutions
2017
Both EN 50522 and IEEE Std. 81 propose the Fall of Potential Method (FPM) to carry out the measurement of the resistance to earth of an Earthing System (ES). However, in urban areas, the recommended distances between the ES and auxiliary electrodes are not easy to respect, due to the presence of buildings and tarmac. Moreover, unknown buried metallic parts, as well as the interconnection among the ESs made by the Distributor System Operator, could modify the earth potential profile of the area, affecting the measurement results. In this paper, the issues that could affect the measurement result if FPM is used in an urban context are presented. A parametric analysis, carried out with Comsol …
