Assessment of Soiling Dynamics and Cleaning Efficiency for Photovoltaic Modules Under Different Dust Environments

Solar RRL, EarlyView.
A laboratory framework reproduces site‐specific soiling and cleaning dynamics of photovoltaic modules using real dusts from contrasting climates. Accelerated humidity–temperature cycling replicates 1 month of outdoor cementation in only ≈ 1.5 days.

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

steel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

Punching shear in flat slab systems – Experimental quantification of unconsidered system influences

Structural Concrete, EarlyView.
Abstract Due to the demand for slender and functional buildings, flat slabs are a frequently used load‐bearing element in buildings. However, the concentrated load introduction at the slab‐column connection is often the governing detail in design due to punching shear failure.

Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy. Design A total of 19 patients who were diagnosed with otosclerosis and underwent surgical treatment in our hospital were collected.

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

Artificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.
