Fitting Analysis of Flow Capacity of Labyrinth Weir Basedon the Length Change of Overflow Leading Edge

Renmin Zhujiang, 2020
Even in the mountain valley reservoir, the labyrinth has a large capacity for overflowunder low head conditions, but its flow capacity decreases significantly with the increase ofweir head.

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

Journal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

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

علوم 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.

Comparison of Scour Properties of Classical and Trapezoidal Labyrinth Weirs

Arabian Journal for Science and Engineering, 2021
Free overfall structures might affect the structural safety of weirs. Thus, it is essential to minimize local scour in the downstream pool to ensure structural safety. In the present study, triangular, trapezoidal, and labyrinth weirs were analyzed numerically for free overfall with the Computational Fluid Dynamics method to estimate local scour depths.

Inhibition of peripheral CB1 receptors modulates food intake and metabolic efficiency in obesity independently of the gut–brain vagal axis

British Journal of Pharmacology, Volume 183, Issue 16, Page 4953-4968, August 2026.
Background and Purpose Obesity involves profound disruptions in neuronal circuits, neuroendocrine communication and the endocannabinoid system. While global blockade of cannabinoid CB1 receptors improves metabolism, its clinical use is limited by neuropsychiatric side effects.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, Volume 33, Issue 4, Page 633-645, August 2026.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Topographic Barriers and Lowland Corridors Structure Gene Flow in the Chagas Vector Rhodnius pallescens Across the Isthmian Forests

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Biogeographic processes can profoundly shape the connectivity and evolutionary potential of arthropod disease vectors. We investigated how Panama's ecological and topographic transitions structure populations of the kissing bug Rhodnius pallescens, the primary vector of the Chagas disease agent Trypanosoma cruzi in the region.

Flow simulation over semicircular labyrinth weir using ANSYS -fluent

Tikrit Journal of Engineering Sciences, 2022
This study investigates the flow of a semicircular labyrinth weir in an open channel by experimental and numerical methods. The experiments were carried out in a channel with a length of 3.5m and width of 0.25m and 0.3m height under five different flow ...

Genome‐Wide SNP Diversity in Natural and Cultivated Populations Informs Restoration Ecology With Three Calamagrostis Species From the Northwest Territories of Canada

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT There is growing demand for data‐driven frameworks to guide robust plant restoration strategies in response to anthropogenic disturbances. Several seed‐sourcing (i.e., provenancing) strategies have been proposed, which balance the use of locally adapted genotypes against mixed genotypes to reduce mutation load or assist migration to anticipate
