Enhancing Ductility of One-way Concrete Slabs Reinforced With Welded Wire Reinforcement

, 2017
A series of research studies have recently identified an issue called strain localization in welded wire reinforced (WWR) members. This phenomenon reportedly concentrates strains at welded cross wire locations and severely limit ductility. Those that identified the phenomenon used it to imply that WWR is unsafe because it does not warn of failure. This

Chewable Soft Gelatin Capsules: Design and Formulation Strategies for a Patient‐Preferred Dosage Alternative

Macromolecular Materials and Engineering, EarlyView.
Chewable softgels are a patient‐preferred alternative to conventional oral forms, offering pleasant taste, fast onset, and suitability for children or patients with swallowing difficulties. However, they present relevant challenges in their formulation: the shell must balance chewability, machinability, and stability, while the fill must mask the ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
