Temporal clear-water scour evolution at rock weirs

Shui kexue jinzhan, 2022
Rock weirs are commonly used eco-friendly river training structures. However, water flow over rock weirs can cause local scour, resulting in structural failure.

Experimental study and performance comparison on various types of rectangular piano key side weirs at a 120° section of a 180° curved channel

Applied Water Science, 2020
Application of side weirs with high effective length is necessary to discharge excessive flows, to control the flow in water conveyance systems, and irrigation and drainage systems.

Piano key weir with sloped parapet wall [PDF]

علوم و مهندسی آبیاری, 2015
Since the one of the application of piano keys weir is use in irrigation and drainage network, and it is possible that with decrease of discharge, the water level during dehydration is faced with a drastic reduction.

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

Advanced Science, EarlyView.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

On the Effect of Width of Weir in the Suppressed Weirs

Transactions of the Japan Society of Mechanical Engineers, 1961
In order to see the effect of width of weir b, experiments are performed for b=0.2, 0.1, 0.05, 0.025, and 0.0125 m when D=0.2 m, and for b=0.025 m when D=0.1 m. According as the magnitude b decreases, the drop of hydraulic gradient (water surface) increases. Consequently, the coefficient of discharge deviates from that of c when b is large.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Streamlining Diagnosis of Bardet–Biedl Syndrome: New Diagnostic Algorithm With Updated Criteria

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Considerable advances have been made in our understanding of Bardet–Biedl syndrome (BBS), particularly in its core clinical features and molecular genetics, warranting an update to the existing diagnostic criteria framework. Using a rigorous, evidence‐based, and consensus‐driven process, a multidisciplinary group of international experts and ...

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Advancing Theory and Practice Concerning CO2e Emissions: A Time‐Based Tool for Organisations

Business Strategy and the Environment, EarlyView.
ABSTRACT Although organisations are increasingly scrutinised on their CO2e emissions, economic growth is frequently encouraged. Eco‐efficiency–based initiatives—‘doing more with less’—could be a solution. The problem is that many organisations (e.g., smaller enterprises without access to specialist knowledge) have difficulties in gauging the impact of ...
