To be sustainable, farmed fish should be environmentally suitable, biologically ideal, socially acceptable and economically viable. As these sustainability indicators (SIs) strongly influence consumers’ fish purchase intent, farms should report them as a balanced source of sustainability information. However, in the literature, little attention has been paid to biological indicators in assessing ...

This Special Issue of Religions approaches “Sámi religion” from a long-term perspective seeing both the past religious practices and contemporary religious expressions as aspects of the same phenomena. This does not refer, however, to a focus on continuity or to a static or uniform understanding of Sámi religion. Sámi religion is an ambiguous concept that has to be understood as a pluralistic ...

Successional processes can be observed for many organisms and resources, but most studies of succession have focused on plants. A general framework has been proposed, advocating that successional patterns in species turnover are predominantly driven by competition, dispersal or abiotic limitation, and that the patterning of species accumulation over time gives clues to which process is most influential ...

Understanding the relationship between remote sensing reflectance, R_rs(λ) and the inherent optical properties (IOPs) of natural waters is potentially a key to improving our ability to determine biogeochemical constituents from radiometric measurements. These relationships are usually described as a function of absorption, <i>a</i>(λ), and backscattering, b_b(λ), coefficients, ...

<i>Background</i> - The COVID-19 pandemic is a global public health emergency and experts emphasize the need for rapid and a high degree of communication and interaction between all parties, in order for critical research to be implemented. We introduce a resource (website) that provides bibliometric analysis showing the current content and structure of the published literature. As new research is ...

Immunofluorescence microscopy is routinely used in the diagnosis of and research on renal impairments. However, this highly specific technique is restricted in its maximum resolution to about 250 nm in the lateral and 700 nm in the axial directions and thus not sufficient to investigate the fine subcellular structure of the kidney’s glomerular filtration barrier. In contrast, electron microscopy ...

This paper addresses the problem of position control or waypoint tracking for an underactuated quadrotor. The proposed control law is what is known as reaction based in the way that the attitude system reacts to errors in the translational motion. This methodology requires no generation of desired attitude or angular velocity and the resulting control law is model-independent in that it does ...

A growing number of older people in Norway receive care services at home. Public policy aims at promoting social safety, preventing social problems and providing recipients of care with the means to live an active and meaningful everyday life together with others. However, health-related services have long been prioritized at the expense of other care services. Our aims are to investigate how ...

Whole-body magnetic resonance imaging (MRI) is increasingly being used for a number of indications. Our aim was to review and describe indications and scan protocols for diagnostic value of whole-body MRI for multifocal disease in children and adolescents, we conducted a systematic search in Medline, Embase and Cochrane for all published papers until November 2018. Relevant subject headings and free ...
