Investigating Performance Properties of Three New Types of UF Membranes for Carwash Sector Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
PVC and its derivatives were used to prepare new types of UF membranes. Membranes had a high degree of removal efficiency of pollutants from carwash wastewater. The morphological SEM cross‐sectional of the membranes reveals to be porous ultrafiltration membranes.

Enhancing Signal Purity in Josephson Structure Measurements

open access: yesAdvanced Physics Research, EarlyView.
A low‐noise signal measurement system for dilution refrigerators is presented, combining multistage cryogenic filtering and electromagnetic shielding to suppress broad‐spectrum noise. The setup enables sub‐nanoampere switching current measurements in Josephson junctions, surpassing commercial systems.

Hypercanines: Not just for sabertooths

open access: yesThe Anatomical Record, EarlyView.
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape

open access: yesThe Anatomical Record, EarlyView.
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.
