Experimental validation and extension of a blade element momentum model for counter-rotation dual-rotor wind turbine with double rotational armature design [PDF]

Wind Energy Science
Small wind turbines face significant challenges in achieving commercial viability due to lower efficiency and higher energy costs compared to utility-scale systems and competing renewable technologies. Counter-rotating dual-rotor wind turbines (CR-DRWTs)

IVyTools: Space–Time Image Velocimetry for Streamflow

River Research and Applications, EarlyView.
ABSTRACT Accurate streamflow measurements are essential for hydrologic monitoring, flood forecasting, and water resource management. Traditional in situ methods, although reliable, are often impractical or unsafe during flood conditions or at inaccessible locations. Image velocimetry techniques offer a potential non‐contact alternative, yet operational

MRI-based anatomical and biomechanical characterization of the human masticatory muscles

Frontiers in Bioengineering and Biotechnology
Biomechanical models of the masticatory muscles quantify the complex force and movement patterns of the masticatory system and are essential for evidence-based diagnosis, treatment planning, and prosthetic care in the craniomandibular region.

Accounting for animal movement during aerial imaging surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Development and characterization of biparental mapping population for the properties of seed and seed coat applicable to seed longevity in soybean (Glycine max (L.) Merrill)

BMC Plant Biology
Background Short life span of soybean seed under ambient storage conditions is a serious challenge for crop production and germplasm maintenance. There are scarce reports on linkage mapping of QTLs for seed longevity, and the molecular mechanisms remain ...

HISTOPATHOLOGICAL EVALUTION OF HEAING OF GASTRIC WOUNDS FOLLOWING ELECTROSURGERY AND CONVENTIONAL SURGERY IN EXPERIMENTAL DOGS [PDF]

Journal of Veterinary and Animal Sciences, 1996
The healing of gastric wounds following electrosurgery and conventional surgery was compared in ten experimental dogs based on histopathological studies. Comparatively an acute and severe inflammatory reaction was a feature of electrosurgical incisions
