Stress wave propagation through grainy, or granular, materials is important for detecting the magnitude of earthquakes, locating oil and gas reservoirs, designing acoustic insulation and designing materials for compacting powders.
Access to green spaces in metro areas--parks, trails, even the tree cover in a neighborhood - is largely associated with income and race, new research indicates. Researchers combined census-block-group demographic and socio-economic data with satellite imagery to analyze access to green spaces and vegetation in two metropolitan areas: Columbus, Ohio, and Atlanta, Georgia. Their study appears in the August issue of the journal Landscape and Urban Planning.
Published in the International Journal of Agricultural Sustainability, their research examined the role of social network brokers - well-connected individuals within a community - in the adoption of innovative farming practices in Battambang Province in North-Western Cambodia. The authors, Dr Petr Matous, Junjian Zhang and Associate Professor Daniel Tan found that less popular farmers were better influencers, compared to their more popular peers.
Scientists at Osaka University show how buildings and moving objects can be virtually removed from real-time images in a process of "diminished reality." This work can be beneficial for urban and campus planners.
With more accurate modeling data, response teams can better predict the search area grid from the air, and reduce emergency response time when lives are on the line.
The study may suggest new strategies to limit virus attacks and prevent or combat diseases like Sars and Covid-19 based on biomedical and engineering principles. The research was conducted by the University of Trento and by the University of Napoli Federico II, in collaboration with researchers at Carnegie Mellon University and at the University of Pittsburgh, in the USA, and with the universities of Palermo and Ferrara, where experiments were carried out
The latest report from the National Institute for Transportation and Communities (NITC), by Marc Schlossberg and Heather Brinton of the University of Oregon, is a guide for city staff and leadership on adopting local policy and code to respond to the emergence of emerging transportation technologies and encourage their responsible use.
An international research team has conducted a field survey on two species of eel native to Japan and other organisms that share the same habitat, revealing for the first time in the world that these eels can act as comprehensive surrogate species for biodiversity conservation in freshwater rivers. It is hoped that conducting activities to restore and protect eel populations will contribute greatly to the recovery and conservation of freshwater ecosystems.
An international study led by the University of Plymouth (UK) suggests islands composed of gravel material can evolve in the face of overtopping waves, with sediment from the beach face being transferred to the island's surface.
Researchers at Linköping University, Sweden, are attempting to convert carbon dioxide, a greenhouse gas, to fuel using energy from sunlight. Recent results have shown that it is possible to use their technique to selectively produce methane, carbon monoxide or formic acid from carbon dioxide and water. The study has been published in ACS Nano.
