    Digitalization in Just-In-Time Approach as a Sustainable Solution for Maritime Logistics in the Baltic Sea Region

    by Olena de Andres Gonzalez, Heikki Koivisto, Jari M. Mustonen, Minna M. Keinänen-Toivola

    This research provides an overview of the process and results of the development and implementation of the Port Activity Application. The aim of the application is to improve the coordination and information exchange mechanisms between the existing systems of ports and ships during piloting ordering process to ensure their effective interoperability, giving a better understanding of the impact of digitalization on the sustainability of seaports and maritime transport. To implement this concept, a system of step-by-step actions was developed, including determining the current situation, developing a business model and business logic for implementing an appropriate information and communication technology (ICT) solution, analysing the local government structure, analysing intermodal information exchange between stakeholders, developing and testing a new ICT tool. The ports of Rauma, Finland, and Gävle, Sweden, were used as pilot ports. As a result of the study, the main bottlenecks in the process of information exchange in ordering pilotage were identified. An improved business model and business logic, that allows the rational use of resources and reduces CO2 emission and the pressure on the environment, was developed. The testbed was conducted in an environment of real port operations. Currently, the open access source code is available for use for maritime cluster actors.

    Rapid Urbanization and Infrastructure Pressure: Comparing the Sustainability Transition Potential of Water and Energy Regimes in Namibia

    by Nina Savela, Jarkko Levänen, Sara Lindeman, Nnenesi Kgabi, Heikki Koivisto, Meri Olenius, Samuel John, Damas Mashauri, Minna M. Keinänen-Toivola

    This article presents a comparative study of the urban water and energy sectors in the coastal city of Walvis Bay in Namibia, where the rapid urbanization places pressure on public infrastructure development. A multidata approach is used to study the ability of the energy and water sectors to adapt to this pressure. Theoretically, the analysis is guided by the systems transition framework. A comparison between the two regimes is made on four dimensions: (1) regime dynamics, (2) level of complexity, (3) level of coordination, and (4) multiplicity of perceptions. The energy regime was found to be more capable of transitioning towards more sustainable practices due to better outcomes in multi-stakeholder engagement, a higher level of transparency, and differing landscape and niche development. The energy regime is also more open for new service providers. The water regime, on the other hand, suffers from overlapping roles and practices as well as non-existent monitoring authorities, which together negatively affect the regime’s transition potential. Both regimes suffer from lack of funding and weak institutional capacities. In conclusion, the transition potential of the studied regimes is found to increase when cross-sectoral governance is strengthened.

    The Seasonality of Nitrite Concentrations in a Chloraminated Drinking Water Distribution System

    by Pirjo-Liisa Rantanen, Ilkka Mellin, Minna M. Keinänen-Toivola, Merja Ahonen, Riku Vahala

    We studied the seasonal variation of nitrite exposure in a drinking water distribution system (DWDS) with monochloramine disinfection in the Helsinki Metropolitan Area. In Finland, tap water is the main source of drinking water, and thus the nitrite in tap water increases nitrite exposure. Our data included both the obligatory monitoring and a sampling campaign data from a sampling campaign. Seasonality was evaluated by comparing a nitrite time series to temperature and by calculating the seasonal indices of the nitrite time series. The main drivers of nitrite seasonality were the temperature and the water age. We observed that with low water ages (median: 6.7 h) the highest nitrite exposure occurred during the summer months, and with higher water ages (median: 31 h) during the winter months. With the highest water age (190 h), nitrite concentrations were the lowest. At a low temperature, the high nitrite concentrations in the winter were caused by the decelerated ammonium oxidation. The dominant reaction at low water ages was ammonium oxidation into nitrite and, at high water ages, it was nitrite oxidation into nitrate. These results help to direct monitoring appropriately to gain exact knowledge of nitrite exposure. Also, possible future process changes and additional disinfection measures can be designed appropriately to minimize extra nitrite exposure.

    Proactive Approach for Safe Use of Antimicrobial Coatings in Healthcare Settings: Opinion of the COST Action Network AMiCI

    by Merja Ahonen, Anne Kahru, Angela Ivask, Kaja Kasemets, Siiri Kõljalg, Paride Mantecca, Ivana Vinković Vrček, Minna M. Keinänen-Toivola, Francy Crijns

    Infections and infectious diseases are considered a major challenge to human health in healthcare units worldwide. This opinion paper was initiated by EU COST Action network AMiCI (AntiMicrobial Coating Innovations) and focuses on scientific information essential for weighing the risks and benefits of antimicrobial surfaces in healthcare settings. Particular attention is drawn on nanomaterial-based antimicrobial surfaces in frequently-touched areas in healthcare settings and the potential of these nano-enabled coatings to induce (eco)toxicological hazard and antimicrobial resistance. Possibilities to minimize those risks e.g., at the level of safe-by-design are demonstrated.
