Persistence of leprosy in northeast Brazil: epidemiological characterization and spatial distribution over a decade.

Leprosy is an infectious disease caused by Mycobacterium leprae, predominantly affecting vulnerable populations. This study analysed the spatial and spatiotemporal distribution of leprosy cases in northeast Brazil and their epidemiological characteristics. An ecological study use...

Influence of Steel Fiber Distribution on the Mechanical Performance of SFRC

Abstract This study investigated the flexural behavior of steel fiber-reinforced concrete (SFRC) with a nonuniform fiber distribution using a layered casting approach. Specimens composed of a fiber-reinforced bottom layer and a conventional concrete top layer (layered SFRC, LSFRC...

Reproducible Multicriteria Reanalysis of a Four-Criterion UASB-Oriented Source Matrix for WWTP Biogas-Recovery Prioritization

This study performs a computationally reproducible multicriteria reanalysis of a four-criterion, UASB-oriented source matrix reported in a 2015 MSc dissertation. Two author-generated numerical scenarios, each containing six WWTP alternatives, are treated as constructed cases rath...

Microparticles of greenish-brown propolis extract: phytochemical, physicochemical characterisation and in vitro dissolution profile

The low solubility of propolis in water and its limited bioavailability reduce the effectiveness of bioactive compounds, demonstrating the necessity of techniques that can overcome these limitations. Spray-drying is a promising approach to overcoming these challenges. In this stu...
