Support for low-carbon energy and opposition to new large dams encourages global development of small hydropower facilities. This support is manifested in national and international energy and development policies designed to incentivize growth in the small hydropower sector while curtailing large dam construction. However, the preference of small to large...
Rapid hydropower development is occurring in China's Yunnan province in response to increasing clean energy demands, exposing potential vulnerabilities of the area's ecosystems, communities, and geopolitical systems. Here, we present original data on the cultures, economics, hydro-politics, and environments of the Nu River basin, based on household surveys, analysis of...
A nivel profesional los bibliotecarios han proclamado un responsabilidad ética que asegure acceso a la información a la población entera. Aún así existen muchas barreras para cumplir este cometido, entre ellos distintos niveles educativos y tecnológicos alrededor del planeta, costes a la hora de obtener información de investigación y concentración...
Ocean Drilling Program (ODP) Leg 204 to Hydrate Ridge, located on the continental slope offshore Oregon (USA), was the first drilling expedition dedicated to understanding gas hydrate processes in accretionary complexes and provided a testbed for a number of different techniques for estimating the gas hydrate content of sediments. It...
Land-associated, sound-scattering layers of mesopelagic micronekton surround the Hawaiian Islands. These animals undergo diel
migrations during which they split into multiple, distinct layers that have differences in animal density, taxonomic composition,
and size. A video-camera system capable of quantitatively estimating the biological constituency of the layers was combined with
a...
In this article, we provide a brief overview of generative artificial intelligence and large language models. We then propose eight critical questions that libraries should ask when exploring this technology and its implications for their communities. We argue that libraries have a unique role in facilitating informed and responsible use...
Internal‐tide generation is usually predicted from local topography, surface tides, and stratification. However, internal tides are often observed to be unrelated to local spring‐neap forcing, appearing intermittently in 3–5 day bursts. Here we suggest a source of this intermittency by illustrating how remotely‐generated shoaling internal tides induce first‐order changes in...
PURPOSE OF THE STUDY: Maintaining perceived psychological control in older adulthood is
beneficial for health, well-being, and adjustment to chronic illness. Theoretically, control over
specific, personally meaningful domains should inform general control beliefs. Thus, the
objective of the present study was to examine perceived control over the exercise domain
(operationalized...
Many industrially important reactions use immobilized enzymes in non-aqueous, organic
systems, particularly for the production of chiral compounds such as pharmaceutical precursors.
The addition of a spacer molecule (“tether”) between a supporting surface and enzyme often
substantially improves the activity and stability of enzymes in aqueous solution. Most “long”
linkers...
