Experimental evaluation of reinforced concrete columns produced with natural perlite aggregates under cyclic loading

Structural Concrete, EarlyView.
Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, EarlyView.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Supersonic transporter (SST) deformity of penile prosthesis: Current management strategies

UroPrecision, EarlyView.
Abstract Supersonic transporter (SST) deformity, also known as floppy glans syndrome, represents a persistent source of post‐operative dissatisfaction among patients undergoing inflatable penile prosthesis (IPP) implantation. Although infection and mechanical failure rates have declined with advances in device design and surgical technique, SST ...

Flame Retardant Polyolefins Using Fibers From Leather Waste: Adjusting Extrusion Variables to Balance the Property Profile

Journal of Vinyl and Additive Technology, EarlyView.
Adjusting extrusion variables are a key to balance the flame retardancy and mechanical properties of polyolefin/leather waste fiber composites. ABSTRACT The extrusion processing variables represent a key to the optimal use of additives and thus the development of flame‐retardant polymer composites. Adjusting the property profile, for example, finding a

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Blended Polypropylene Fibers

Journal of Macromolecular Science, Part A, 1998
The preparation, and especially the dyeability of blended fibers polypropylene and terpolymer acrylonitrile-butadiene-styrene and/or polypropylene and polystyrene, respectively are presented in this paper. Modified polypropylene fibers fix the dyestuffs much better and have lower tenacity according to the amount of the additive.
