Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

Sustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing

Experimental reintroduction of woody debris on the Williams River, NSW: geomorphic and ecological responses [PDF]

, 2004
A total of 436 logs were used to create 20 engineered log jams (ELJs) in a 1.1 km reach of the Williams River, NSW, Australia, a gravel-bed river that has been desnagged and had most of its riparian vegetation removed over the last 200 years.

Microporous Self‐Assembled Pd(II) Tetrahedral Cages for Rapid and Reversible Multi‐Phase Sequestration of Iodine and Methyl Iodide

Small, EarlyView.
This work reports a family of microporous, self‐assembled tetrahedral coordination cages that efficiently capture iodine, polyiodides, and methyl iodide from vapor, aqueous, and organic media. The cages display exceptional uptake capacities, rapid kinetics, and high selectivity, enabling the first dynamic vapor‐phase iodine capture by coordination ...

Investigating the effect of curved shape of bridge abutment provided with collar on local scour, experimentally and numerically

Ain Shams Engineering Journal, 2015
Scour around bridge supports such as abutments can result in structural collapse and loss of life and property, so there is a need to control and minimize the local scour depth.

Mechanics‐based model for cold joints in reinforced concrete members

Structural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Field study of scour around Bridge piers in the transitional section of the Qiantang River

Ain Shams Engineering Journal
With the rapid development of bridge construction, the safety of bridges under complex hydrological conditions has become an increasingly critical issue. This study investigates the local scour characteristics of bridge piers in the transition section of

‘CLOSING THE CARBON LOOP’: Climate Policy Discourses and the Material Politics of Municipal Waste‐to‐Biofuel Programs

International Journal of Urban and Regional Research, EarlyView.
Abstract Waste‐to‐biofuel (WTB) programs have gained popularity as a municipal circular economy and an emissions reduction strategy. The upgrading of biofuels to renewable natural gas (RNG) has drawn particular interest, as RNG can displace conventional fossil fuels in any existing natural gas end use and be delivered through existing pipeline ...

Local scour at group of bridge piers founded in gravel bed in staggered arrangement

Results in Engineering
Local scour around bridge piers is the common cause of undermining of bridge foundation. Many researchers have studied local scour around bridge pier in finer sediment bed.

Scour Damage Detection and Structural Health Monitoring of a Laboratory-Scaled Bridge Using a Vibration Energy Harvesting Device

Sensors, 2019
A vibration-based bridge scour detection procedure using a cantilever-based piezoelectric energy harvesting device (EHD) is proposed here. This has an advantage over an accelerometer-based method in that potentially, the requirement for a power source ...
