Magnetron‐Sputtered Niobium‐Coated Biochar for Reusable Adsorption of Ivermectin and Diclofenac From Water

Adelício Lucas Alberto · Sabrina Frantz Lütke · Yasmin Vieira · Cesar Aguzzoli · y 4 más

ABSTRACT Biochar was surface‐modified using the Magnetron Sputtering technique, coating it with thin films of niobium to improve its selectivity and reusability for the removal of ivermectin (IVM) and diclofenac (DCF) from water. Batch experiments were conducted to investigate the effects of pH and temperature, adsorpt...

Monte Carlo Modeling of Asphalt Surface Wear under Studded-Tire Traffic

D. Loaiza-Monsalve · J.-P. Bilodeau · B. Fournier · Félix Doucet · y 1 más

Abstract In this paper, the evolution of surface damage of asphalt pavements under studded tire traffic is examined using a combined experimental and stochastic modeling approach. Laboratory tests on six asphalt mixtures were integrated into a Monte Carlo framework that represents rutting wear as the cumulative effect...

Cryopreservation-induced proteomic alterations in Pêga donkey (Equus asinus) spermatozoa

Camilo Jose Ramirez-Lopez · Isabella Cristina Tolêdo Alves Costa · Wassali Valadares de Sousa · Yara Martins da Silva · y 10 más

Semen cryopreservation is a key tool for assisted reproduction and genetic conservation, but its efficiency remains limited in donkeys, compromising post-thaw sperm quality. This study aimed to characterize the proteomic profile of Pêga donkey spermatozoa and to investigate molecular mechanisms associated with cryopres...

Prevalence, incidence, and 6-years stability of metabolically unhealthy normal weight́s phenotype in u.s. hispanic/latino adults

Milton Fabian Suarez-Ortegón · Paola Filigrana · Wenyan Ma · Amber Pirzada · y 7 más

AIMS: Normal-weight individuals who exhibit cardiometabolic abnormalities similar to those linked to higher body weight (metabolically unhealthy normal-weight, MUNW) are difficult to detect in clinical practice. We examined factors associated with prevalent and 6-years incident MUNW, and the stability of MUNW over this...
