In modern times, assessing the impact of climate change on the vulnerability of radiological practices is necessary to implement risk management policies and secure facilities.
Scientific, political and socio-economic aspects of the dossier on plastic pollution solicited by the European Commission.In November 2017, as part of the EU Plastics Strategy, the European Commission (EC) requested that the European Chemical Agency (ECHA) develop a dossier on microplastics' restriction under REACH. REACH is a EU chemical regulation adopted in 2006, and its aims are the protection of human health and the environment.
The requested restriction process concerns not only environmental and health risk assessments but is closely related to socio-economic impacts within the union. Therefore, several EU committees, such as the Risk Assessment Committee (RA) and the Committee for Socio-Economic Analysis (SEA) are involved in the examination of the preparatory study submitted by ECHA.
The whole restriction process is clearly described by E. Kentin in European Physical Journal Plus (EPJ Plus).

In modern times, assessing the impact of climate change on the vulnerability of radiological practices is necessary to implement risk management policies and secure facilities.
Global warming goes hand in hand with increasing instances of climate-related natural disasters such as storms, droughts, floods, and rainfalls. The effects of climate change, beyond having a tremendous impact on ecosystems, are also remarkable risk factors for anthropogenic systems (some examples include infrastructure, agriculture, and tourism).
In Europe, flooding events have increased in the last few years, particularly in the Mediterranean region, which has a high climatic risk because of its complex orography and the presence of human activities.
In the European Physical Journal Plus, G. M. Contessa et al. analyze the influence of climate change on human activities involving ionizing radiation in Italy.

History revealed by integrating multiple layers of clues from medieval village remnants
Archaeologists now have new tools for studying the development of medieval villages and the transformation of the historical landscapes surrounding them. In a study recently published in EPJ Plus, scientists have attempted to reconstruct the history of Zornoztegi, an abandoned medieval village located in the Basque Country, Spain. To do so they rely on the various analysis methods available to archaeologists, including radiocarbon dating, archaeological and historical records, archaeobotanical and optical microscope analyses of samples found on the site, together with a statistical analysis model. Paola Ricci from the University of Campania “Luigi Vanvitelli” in Italy and colleagues used this approach to establish the history of the village in the time leading up to the Middle Ages.

Will the oceans be clean again? - How to search for and identify microplastics in the marine environment using digital holography.
In recent years the pollution of soil and oceans has drastically increased, affecting the food chain and consequently causing damage to plant life, contaminating fauna and damaging human health.
Among the major contaminants, microplastics play a relevant role and even though several techniques have been proposed to analyse the presence of such material in water, the overall data are largely incomplete. A group of Italian researchers (F. Merola et al.) have proposed using a non-invasive technique based on digital holography to search for and reconstruct the shape of different types of microplastics in water.
They report in the European Physical Journal Plus (EPJ Plus) how it is possible to identify different fragments of the most used types of plastic (such as PET, PVC, PP, PE and PS), which heavily contaminate the seas, and how this high-resolution technique is able to distinguish plastics from organisms such as diatoms, a major group of microalgae living in the marine environment.
EPJ Plus Focus Point - Systems and Security: Advanced Methods with Chaos and Complexity
- Details
- Published on 05 September 2018
Complexity, as far as information theory is concerned, plays an important role in extracting the amount of uncertainty in dynamics. Several entropy-based measurements have been successfully implemented to quantify the divergence of a system. Uncertainty also plays an effective role, in the field of cryptography, in generating secret keys and to design the most secure model. Recently, real applications have been implemented considering the effect of dynamical complexity, in the field of optical communications, using semiconductor lasers. This EPJ Plus Focus Point edited by Santo Banerjee is a collection of research articles based on the recent developments of communication schemes using chaos and dynamical complexity. The results have been implemented with dynamical models, circuit design, complex networks along with their applications in image, video and optical communications.
EPJ Plus Focus Point - Modelling Complex Real-World Problems with Fractal and New Trends of Fractional Differentiation
- Details
- Published on 14 August 2018
Differential operators with non-singular kernels have been suggested recently and have raised interest in many fields of science, technology and engineering. They have being recognized to have brought news tools in applied mathematics and other applied sciences, as they are able to capture and observe a more complex physical behavior of nature. One of their unique properties is crossover behavior; in particular, their ability to capture Brownian motion, stochastic processes, anomalous diffusion and power-law dependency processes. This Focus Point on Modelling Complex Real-World Problems with Fractal and New Trends of Fractional Differentiation edited by A. Atangana, Z. Hammouch, G. Mophou and K. M. Owolabi in EPJ Plus aims at capturing current developments and initiatives of these new mathematical tools in modeling real-world problems. It focuses on new numerical and analytical methods for solving the complex real-world problems arising in physics. Several new results were presented and published in this Focus Point. In particular, a revolutionary paper has led to the extension of the field of non-local operators and their applications. The particular attention devoted to these new mathematical tools leaves no doubt on the fact that the future of modeling real-worl problems relies on these operators.

A new study reveals how to best evaluate the circulation of magnetic fields around closed loops
Concerns about the effects of magnetic fields on human health require careful monitoring of our exposure to them. Mandatory exposure limits have been defined for electric and hybrid vehicle architectures, in domestic and work environments, or simply to shelter sensitive devices from unintended sources of magnetic disturbance. In a new study published in EPJ Plus, physicists Jose Manuel Ferreira and Joaquim Anacleto from the Trás-os-Montes e Alto Douro University in Portugal develop a method for deriving an approximate value of the circulation around a loop of the magnetic field generated by the flow of electric current in an arbitrarily-shaped wire of a given length.

New model examines the relative role of random interactions between individuals in a crowd compared to interactions stemming from their eagerness to be on their way
Ever found yourself crushed in a metro station at rush hour? The mathematician Carlo Bianca and physicist Caterina Mogno, both from the engineering research lab ECAM-EPMI in Cergy-Pontoise, France, have developed a new model to study the movement of crowds exiting a metro station. In a recent study published in EPJ Plus, they have for the first time employed models typically used to study gases consisting of a large number of molecules that collide at random (known as thermostatted kinetic theory) to study the consequences of the different interactions occurring among pedestrians in a crowd while exiting a metro station.
EPJ Plus Focus Point - Transition to Sustainable Energy Systems
- Details
- Published on 07 March 2018
The “Focus Point on the Transition to Sustainable Energy Systems” in the European Physical Journal Plus (EPJ Plus) tries to answer central questions regarding the planned Energy Transition, focusing on the power sector in Europe. Important is the role played by intermittent renewables as a low carbon electricity source, central in the plans by the EU Commission in its Energy Roadmap 2050. Their intermittency however strongly reduces efficiency and security of supply and back up by other systems is unavoidable – large storage and/or nuclear and/or fossil based. Storage of excess electricity production by intermittent renewables at the level required seems far-fetched at this moment and much more research will be needed before this can substantially contribute. With a limited contribution of dispatchable renewable electricity (hydro, bio-fuels etc.) and excluding à priori nuclear power, on various grounds, a continued use of fossil fuels imposes itself to guarantee a secured supply of electricity – in strong contrast with the original aims of the EU Energy Roadmap 2050. A rational debate involving all options is urgently needed and it is hoped that the set of papers in this focus point can contribute to improve insights in a determining factor for the future of our children and grandchildren.
