Novi nalazi nezavičaje vrste mnogočetinaša, Chaetozone corona (Polychaeta: Cirratulidae), u Jadranskom moru

Several specimens of the alien polychaete Chaetozone corona were encountered at sites along the Italian coasts of the Adriatic Sea between 2006 and 2015, indicating its successful establishment in the area. Morphological variability between specimens from the North Adriatic and the South Adriatic was detected. Methyl Green staining patterns revealed further minor differences suggesting the presence of two slightly different populations. Chaetozone corona does not appear to be invasive in natural conditions, but it appears more abundant in polluted port sediments, what may represent the main source of introduction.Nekoliko primjeraka nezavičajnog mnogočetinaša Chaetozone corona pronađeno je uzduž talijanske obale Jadranskog mora između 2006. i 2015. godine, što ukazuje na uspješnu uspostavu populacije ove vrste na tom području. Ustanovljena je morfološka varijabilnost između uzoraka iz Sjevernog i Južnog Jadrana. Metilni zeleni oblici/obrasci bojenja otkrili su daljnje manje razlike ukazujući na prisutnost dvije neznatno različite populacije. Chaetozone corona izgleda da se ne ponaša invazivno u prirodnim uvjetima, no čini se da je oblilnija u zagađenim lučkim sedimentima, što može predstavljati glavni izvor unosa

Data Shepherding in Nanotechnology : The Exposure Field Campaign Template

In this paper, we demonstrate the realization process of a pragmatic approach on developing a template for capturing field monitoring data in nanomanufacturing processes. The template serves the fundamental principles which make data scientifically Findable, Accessible, Interoperable and Reusable (FAIR principles), as well as encouraging individuals to reuse it. In our case, the data shepherds’ (the guider of data) template creation workflow consists of the following steps: (1) Identify relevant stakeholders, (2) Distribute questionnaires to capture a general description of the data to be generated, (3) Understand the needs and requirements of each stakeholder, (4) Interactive simple communication with the stakeholders for variables/descriptors selection, and (5) Design of the template and annotation of descriptors. We provide an annotated template for capturing exposure field campaign monitoring data, and increase their interoperability, while comparing it with existing templates. This paper enables the data creators of exposure field campaign data to store data in a FAIR way and helps the scientific community, such as data shepherds, by avoiding extensive steps for template creation and by utilizing the pragmatic structure and/or the template proposed herein, in the case of a nanotechnology project (Anticipating Safety Issues at the Design of Nano Product Development, ASINA).In this paper, we demonstrate the realization process of a pragmatic approach on developing a template for capturing field monitoring data in nanomanufacturing processes.

Technical guidance on monitoring for the Marine Stategy Framework Directive

The Marine Directors of the European Union (EU), Acceding Countries, Candidate Countries and EFTA Countries have jointly developed a common strategy for supporting the implementation of the Directive 2008/56/EC, “the Marine Strategy Framework Directive” (MSFD). The main aim of this strategy is to allow a coherent and harmonious implementation of the Directive. Focus is on methodological questions related to a common understanding of the technical and scientific implications of the Marine Strategy Framework Directive. In particular, one of the objectives of the strategy is the development of non-legally binding and practical documents, such as this technical guidance on monitoring for the MSFD. These documents are targeted to those experts who are directly or indirectly implementing the MSFD in the marine regions. The document has been prepared by the Joint Research Centre of the European Commission (JRC) with the contribution of experts from Member States, Regional Seas Conventions and ICES and following consultation of the Working Group on Good Environmental Status.JRC.H.1-Water Resource

Monitoring and Optimisation of Ag Nanoparticle Spray-Coating on Textiles

An automatic lab-scaled spray-coating machine was used to deposit Ag nanoparticles (AgNPs) on textile to create antibacterial fabric. The spray process was monitored for the dual purpose of (1) optimizing the process by maximizing silver deposition and minimizing fluid waste, thereby reducing suspension consumption and (2) assessing AgNPs release. Monitoring measurements were carried out at two locations: inside and outside the spray chamber (far field). We calculated the deposition efficiency (E), finding it to be enhanced by increasing the spray pressure from 1 to 1.5 bar, but to be lowered when the number of operating sprays was increased, demonstrating the multiple spray system to be less efficient than a single spray. Far-field AgNPs emission showed a particle concentration increase of less than 10% as compared to the background level. This finding suggests that under our experimental conditions, our spray-coating process is not a critical source of worker exposure
