Decades of beauty: Achieving aesthetic goals throughout the lifespan

Journal of Cosmetic Dermatology, Volume 22, Issue 11, Page 2889-2901, November 2023., 2023
Abstract Background Several elements, including age, influence judgments of beauty and attractiveness. Aging is affected by intrinsic factors (e.g., genetics, race/ethnicity, anatomical variations) and extrinsic factors (e.g., lifestyle, environment).

Investigation of turbulent flows using spillway models aiming to aid downstream migration of fish

River Research and Applications, Volume 39, Issue 6, Page 1110-1121, July 2023., 2023
Abstract Dams and other flow control structures constitute obstacles to upstream and downstream aquatic habitats, reducing life‐cycle success and even eliminating diadromous and potamodromous fish species from river basins. Providing effective passage past hydroelectric dams is critical for restoring habitat connectivity and sustaining populations of ...

Carbon and Water Fluxes of the Boreal Evergreen Needleleaf Forest Biome Constrained by Assimilating Ecosystem Carbonyl Sulfide Flux Observations

Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 7, July 2023., 2023
Abstract Gross primary production (GPP) by boreal forests is highly sensitive to environmental changes. However, GPP simulated by land surface models (LSMs) remains highly uncertain due to the lack of direct photosynthesis observations at large scales. Carbonyl sulfide (COS) has emerged as a promising proxy to improve the representation of GPP in LSMs.

Intercomparison of Atmospheric Carbonyl Sulfide (TransCom‐COS; Part One): Evaluating the Impact of Transport and Emissions on Tropospheric Variability Using Ground‐Based and Aircraft Data

Journal of Geophysical Research: Atmospheres, Volume 128, Issue 6, 27 March 2023., 2023
Abstract We present a comparison of atmospheric transport model (ATM) simulations for carbonyl sulfide (COS), within the framework of the atmospheric tracer transport model intercomparison project “TransCom‐COS.” Seven ATMs participated in the experiment and provided simulations of COS mixing ratios over the years 2010–2018, using state‐of‐the‐art ...

Numerical and experimental models applied to an ogee crest spillway and roller bucket stilling basin

RBRH, 2020
Traditionally, reduced physical models are used to allow control, instrumentation and experimental evaluation of flow. More recently, computational fluid dynamics (CFD) has emerged as a tool that allows numerical modeling of flows and can complement the ...

Numerical Investigation of Guide Walls Geometry at the Entrance of Dam Spillway (Case Study: Karun-3 Dam)

علوم آب و خاک, 2022
One of the most important hydraulic structures in a dam is the spillway. The design of the ogee spillway crest is based on the lower profile of the free-flow jet passing through the sharp-crested weir.
