Sustainable sediment management in Jordanian dams: Feasibility, economic viability, and agricultural reuse potential [PDF]

open access: yesJournal of Water and Land Development
Jordan has long faced severe water scarcity, which has significant implications for agriculture, industry, and domestic consumption. This crisis is further exacerbated by climate change, population growth, regional conflicts, and unsustainable water use.

Does a decision support tool designed to depict West Nile virus risk explain variation in ruffed grouse Bonasa umbellus use of managed forests?

open access: yesWildlife Biology, EarlyView.
Infectious diseases are commonly cited as significant contributors to wildlife population declines. It is, therefore, important to investigate the extent to which tools designed to mitigate the effects of infectious diseases explain wildlife responses to habitat management.

Startup Characteristics of Dredging Thermal Protection Structures

open access: yes气体物理
Dredging thermal protection, as a semi-active thermal protection method, is characterized by its simple structure and the absence of the need to carry additional coolants, making it suitable for the leading edge thermal protection of hypersonic vehicles.

Impact of Klaipėda port jetties reconstruction on adjacent sea coast dynamics / Rekonstruotųjų klaipėdos uosto molų įtaka gretimų jūros krantų dinamikai

open access: yesJournal of Environmental Engineering and Landscape Management, 2012
During the reconstruction of 2001–2002, the Klaipėda port jetties were lengthened (the northern jetty by 205 m and the southern by 278 m). These works produced an impact on dynamic coastal processes in the neighbourhood of the port. The evaluation of the

Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

open access: yesWildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Optimization Design of a Winch Suction Underwater Dredging Robot Using Orthogonal Experimental Design

open access: yesJournal of Marine Science and Engineering
In marine engineering and water conservancy projects, dredging often occurs due to silt accumulation, which can impede the long-term development of water ecosystems and water storage systems. To enhance dredging efficiency and the performance of dredging

The wolf is back! Non‐consumptive effects of the return of a large carnivore on the use of supplementary feeding sites by roe deer

open access: yesWildlife Biology, EarlyView.
Understanding how prey species tradeoff predation risk and resource acquisition is particularly important for advancing our knowledge of predator–prey relationships. We investigated this by studying the use of concentrated anthropogenic resources, namely supplementary feeding sites, by roe deer Capreolus capreolus before and after grey wolf Canis lupus

Sediment Resuspension and Deposition on Seagrass Leaves Impedes Internal Plant Aeration and Promotes Phytotoxic H2S Intrusion

open access: yesFrontiers in Plant Science, 2017
HIGHLIGHTS:Sedimentation of fine sediment particles onto seagrass leaves severely hampers the plants' performance in both light and darkness, due to inadequate internal plant aeration and intrusion of phytotoxic H2S.Anthropogenic activities leading to ...

Development of ± 550 kV DC GIS Basin Insulator

open access: yesHigh Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.
