Numerical and experimental study of the combination of labyrinth weir with orifice and its effect on discharge coefficient

open access: yesعلوم آب و خاک, 2021
The combination of a labyrinth weir with an orifice is a proper solution for floating material to pass over the weir and transfer sediment through the orifice. Additionally, creating a slot in the overflow wing leads to higher discharge.

Repeatable Genomic Outcomes Along the Speciation Continuum: Insights From Pine Hybrid Zones (Genus Pinus)

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Hybridization is a widespread evolutionary process and a key source of evolutionary novelty. Despite intensive study, the extent to which hybridization is deterministic and repeatable, particularly in recurrent contact events involving the same species under varying ecological conditions, remains unclear. Here, we investigated three replicated

Comparison of Discharge Coefficient Between Arced Piano Key Weir and Non-Arc Piano Key Weirs [PDF]

open access: yesمهندسی منابع آب, 2020
In this paper, discharge coefficient of arced piano key weir compared against two models of normal or fashionable piano key weirs with no arc in their plan. The arced piano key weirs are less investigated. Piano key weirs are pretty new sort of labyrinth

Tracking Long‐Term Trends in Sockeye Salmon (Oncorhynchus nerka) Population Dynamics Using Sterol and Stanol Biomarkers in Lake Sediments

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract We analyzed biomarkers, including sterols, stanols, and δ15N, in sediment cores from lakes with well‐documented sockeye salmon return histories. Our goal was to improve estimates of past changes in salmon escapement, that is, the population that return to their freshwater nursery lakes, inferred using sediment biogeochemical markers ...

Experimental study and modelling discharge coefficient of trapezoidal and rectangular piano key weirs

open access: yesApplied Water Science, 2020
Crest length is an important parameter in influencing the discharge handling capacity of a weir. Nonlinear weirs with longer crests are cost effective alternatives for those existing dam structures which are more susceptible to failure due to loss of ...

Age‐Dependent Effects of Loss of Contactin‐Associated Protein‐Like 2, an Autism‐Associated Gene, on the Acquisition and Recall of Fear Memory

open access: yesAutism Research, Volume 18, Issue 5, Page 1011-1023, May 2025.
ABSTRACT The contactin‐associated protein‐like 2 (Cntnap2) gene is relevant to autism spectrum disorder (ASD), which is associated with age‐specific structural alterations in limbic brain regions. The Cntnap2 gene encodes for the contactin‐associated protein‐like 2 (CASPR2) protein, and CASPR2 protein levels are high in the amygdala, a limbic region ...

MISFITS, POWER, AND HISTORY: RETHINKING ABILITY THROUGH AN ANIMAL LENS

open access: yesHistory and Theory, Volume 64, Issue 1, Page 75-95, March 2025.
ABSTRACT In this article, we construct a critical history of “ability” by focusing on the specific case study of dark‐dwelling animals and the ways in which they have been understood over the course of modernity. Such creatures were frequently the subjects of assumptions and judgments about what they could and could not do.

Downstream Flood Inundation Assessment Due to Dam Breach of Dudhkoshi Storage Hydroelectric Project Using HEC‐RAS 2D

open access: yesAdvances in Civil Engineering, Volume 2025, Issue 1, 2025.
Dam breach is rare but catastrophic event that occurs when a dam fails and releases impounded water downstream causing significant damage. Dam breach has a low probability of occurrence but carries high risk of destruction. Dudhkoshi Storage Hydroelectric Project (DKSHEP) concrete‐faced rock‐fill dam (CFRD) was studied for dam breach under overtopping ...

Application of the Evolutionary Methods in Determining the Discharge Coefficient of Triangular Labyrinth Weirs

open access: yesعلوم آب و خاک, 2019
A labyrinth weir is a nonlinear weir folded in the plan-view which increases the crest length and the flow rate for a given channel width and an upstream flow depth.

Concordant Signal of Genetic Variation Across Marker Densities in the Desert Annual Chylismia brevipes Is Linked With Timing of Winter Precipitation

open access: yesEvolutionary Applications, Volume 17, Issue 12, December 2024.
ABSTRACT Climate change coupled with large‐scale surface disturbances necessitate active restoration strategies to promote resilient and genetically diverse native plant communities. However, scarcity of native plant materials hinders restoration efforts, leading practitioners to choose from potentially viable but nonlocal seed sources.
