<p>The Open Hydrosystem Information Network (OpenHi.net) is a state-of-the-art information infrastructure for the collection, management and free dissemination of hydrological and environmental information related to Greece’s surface water resources. It was launched two years ago as part of a the national research infrastructure “Hellenic Integrated Marine Inland water Observing, Forecasting and offshore Technology System” (HIMIOFoTS), which also comprises a marine-related component (https://www.himiofots.gr/). The OpenHi.net system receives and processes real-time data from automatic telemetric stations that are connected to a common web environment (https://openhi.net/). In particular, for each monitoring site it accommodates stage measurements, raw and automatically post-processed. Furthermore, in some specially selected sites time series related to water quality characteristics (pH, water temperature, salinity, DO, electrical conductivity) are provided. The web platform also offers automatically-processed information in terms of discharge data, statistics, and graphs, alerts for extreme events, as well as geographical data associated with surface water bodies. At the present time, the network comprises about 20 stations. However, their number is continuously increasing, due to the open access policy of the system (the platform is fully accessible to third-parties uploading their data). In the long run, it is envisioned that a national-scale hydrometric infrastructure will be established, covering all important rivers, lakes and reservoirs of the country.</p>

The application of e-Science technologies to disciplines in the arts and humanities raises major questions as to how those technologies can be most usefully exploited, what tools and infrastructures are needed for that exploitation, and what new research approaches can be generated. This paper reviews a number of activities in the UK and Europe in the last 5 years which have sought to address these questions through processes of experimentation and targeted infrastructure development. In the UK, the AHeSSC (Arts and Humanities e-Science Support Centre) has played a coordinating role for seven projects funded by the Arts and Humanities e-Science Initiative. In Europe, DARIAH (Digital Research Infrastructure for the Arts and Humanities) has sought to develop a deeper understanding of research information and communication in the arts and humanities, and to inform the development of e-infrastructures accordingly. Both sets of activity have indicated a common requirement: to construct a framework which consistently describes the methods and functions of scholarly activity which underlie digital arts and humanities research, and the relationships between them. Such a ‘methodological commons’ has been formulated in the field of the digital humanities. This paper describes the application of this approach to arts and humanities e-Science, with reference to the early work of DARIAH and AHeSSC.

This paper reports the results of research into air, water and oil flow through pipes filled with open-cell metal foams, which form a material with a considerable potential for application in the design of process equipment. This study applied three metal foams with various geometrical parameters. The objective of the experiments involved the measurement of pressure drop within a relatively large range of the variability of the flow conditions. On the basis of data from the literature and analysis of the results of experiments, an assessment was undertaken concerned with the influence of the geometrical parameters of the foams as well as velocities and fluid properties on the flow regime and pressure drop. The results demonstrate that the theory concerned with the fluid flow through porous media has a limited application with regard to metal foams due to the considerable turbulence of the flow through such foams. If flow occurs in other conditions than laminar regime, the permeability of metal foams is relative not only to the geometrical structure of the foams but also depends on the properties and velocity of the fluid. The present study demonstrated that the assessment of the flow regime can apply the modified Reynolds number in which the characteristics dimension is defined on the basis of the parameters accounting for the geometrical foam structure. Three flow regimes were distinguished – laminar flow, transient Forchheimer and transient Froud flow. The ranges corresponding to the occurrence of the particular flow regimes were subsequently determined.

Abstract This commentary focuses on three points: the need to consider semiotic ideologies of both researchers and autistic people, questions of commensurability, and problems with “the social” as an analytical concept. It ends with a call for new research methodologies that are not deficit-based and that consider a broad range of linguistic and non-linguistic communicative practices.
