Effects of anthropogenic magnetic fields on the behavior of a major predator of the intertidal and subtidal zones, the velvet crab Necora puber.

With the progress of the offshore renewable energy sector and electrical interconnection projects, a substantial rise in the number of submarine power cables is expected soon. Such cables emit either alternating or direct current magnetic fields whose impact on marine invertebrates is currently unknown and hardly studied. In this context, this study aimed to assess potential short-term exposure (30 min) effects of both alternating and direct magnetic fields of increasing intensity (72-304 μT) on the behavior of the high-ecological value velvet crab (Necora puber).

Insights into the behavioural responses of juvenile thornback ray Raja clavata to alternating and direct current magnetic fields.

As part of energy transition, marine renewable energy devices (MRED) are currently expanding in developed countries inducing the deployment of dense networks of submarine power cables. Concern has thus raised about the cable magnetic emissions (direct or alternating current) because of potential interference with the sensorial environment of magneto-sensitive species, such as sharks and rays. This study sought to assess the short-term behavioural responses of juvenile thornback rays (Raja clavata) (n = 15) to direct and alternating (50 Hz) uniform 450-μT artificial magnetic fields using 1 h focal-sampling design based on a detailed ethogram.

Electroconvulsive Therapy in Germany: Development Over 8 Years With a Background of 4 Decades.

Objectives: The use of electroconvulsive therapy (ECT) in Europe varies broadly between the extremes of Sweden on one side and Italy on the other. Here, we document the frequency, practice and standards of ECT in Germany in 2016, compare it with a survey of 2008, and describe the historical background.

Methods: A questionnaire was sent electronically to the 396 psychiatric institutions in Germany.

[The public health department of the Western French Guiana Hospital: a 5-year return of experience].

Introduction: The western French Guiana hospital (Chog) is atypical. The creation of a public health department (PSP) is the result of a willingness of the institution to respond to public health issues on its territory. The main objective of this article is to identify the levers and impediments for the development of public health activities within this hospital, after five years of implementation.
