Local Environment in Pitting Corrosion of Aluminum
The pH and chloride microsensors were used to study propagation and repassivation of pits on pure aluminum in pH 11 NaCl solution. It was concluded that the pH inside a growing pit was around 2.7, and the chloride concentration was higher than the saturation concentration. After current to the pit …

Network modularity and local environment similarity as descriptors of protein structure
… for each atom of the protein based on its local environment, known as a Smooth Overlap of Atomic Positions (SOAP) descriptor. Using these descriptors we can perform overall comparisons of the subregions identified above. In addition, by comparing the descriptors of a set of proteins known …

Senses and Local Environment: The Case of Larabanga in the Northern Region of Ghana
… everyday activities deepens our understanding of local people’s relations with the environment. This study was conducted in Larabanga, Ghana, employing anthropology of the senses and phenomenology. The study reveals that people acquire ways of doing things and organizing their lives through their …

The socio-cultural practices of the Dorset rock climbing community towards the local environment.
… to be community-driven and suggests that locality in rock climbing is acquired through knowledge, skills, bonds and friendship, rather than location and geographic proximity. The research also suggests that rock climbing has the ability to take rock climbers to the most secluded of areas. …

Examining secondary students’ mental models of a local environment after an experiential learning field trip
… students will construct a new model of the environment using prior experiences combined with new information gained during an environmental education field trip. It is hypothesized that the outdoor field trip will be a useful tool for presenting new knowledge due to the active engagement of …

New Active Green Environments (New Age): Older Adults' Perceptions About Physical Activity Opportunities in Their Local Environment
… design studies consistently find that the environment can act to serve as a barrier to physical activity, as well as a facilitator for activity options. Recent research suggests that reconfiguring the built environment in a way to increase the number and variety of opportunities for …

Local Viscosity and Environment on the Nanometer Scale
… was built and used to understand the local environment and viscosity. The rotational correlation time constants by the fluorescence anisotropy provide the information on the hydrodynamic volume and local viscosity near the probe. Instead, the fluorescence lifetime does the local …

Land Material Geometry: Spline Construction with Invasive Species in a time of Water Crisis in the Colorado River Basin
… reciprocal and reparative relationship with the local environment and ecology rather than extractive means. It suggests material sourcing tamarisk, an invasive species in southwestern desert river systems that exacerbate strains on water availability, thus, removing the plant, yet maintaining its …

Long-term dynamics and theoretical considerations in coral holobiont adaptation
Corals are predicted to adapt to environmental change in two ways: through the nuclear evolution of the host and/or through acquiring new, more suitable symbiotic partners. Given the rapid rate of climate change, considerable attention has focused on the latter, as new symbiotic partnerships could, …
