Links between single maltodextrin particles properties and powder functionality.

Maltodextrins are extensively used in the food industry to shape the physicochemical properties of food products. This multiscale study investigates three different Dextrose Equivalent (DE) maltodextrins as model matrices to elucidate the relationship between techno-functional behaviors and single particle surface properties. It was evidenced that environmental variations and glass transition influence single particle properties, significantly impacting the powder bulk behavior.

Are public meetings effective platforms for gathering environmental management preferences that most local stakeholders share?

This analysis tests the theory of the collective action problem by comparing data collected from public meetings with data collected through a random sample of households, to better understand how representative preferences expressed during public meetings are of local stakeholders within a defined social area of influence. While previous studies have focused on the lack of representative participation at public meetings, this work moves beyond the concepts of who comes to the table and why and instead, explores the way that a public engagement process, may or may not provide planners with a representative understanding of local stakeholder preferences. The findings suggest that even when starting with a comprehensive stakeholder analysis, creating space for facilitated dialogue, and carefully curating discussions to focus on shared preferences, public meetings - though highly valuable as a tool for engagement - may not be effective platforms for gathering a comprehensive understanding of the land management preferences that most local stakeholders share.

Electron Microscopy Imaging of Zinc Soaps Nucleation in Oil Paint.

Using the recently developed techniques of electron tomography, we have explored the first stages of disfiguring formation of zinc soaps in modern oil paintings. The formation of complexes of zinc ions with fatty acids in paint layers is a major threat to the stability and appearance of many late 19th and early 20th century oil paintings. Moreover, the occurrence of zinc soaps in oil paintings leading to defects is disturbingly common, but the chemical reactions and migration mechanisms leading to large zinc soap aggregates or zones remain poorly understood.

Integrated recovery management model for ex-offenders with co-occurring mental health and substance use disorders and high rates of HIV risk behaviors.

This paper provides outcomes from an evaluation of a federally funded program combining HIV prevention services with an integrated mental health and substance abuse treatment program to a population of primarily African American ex-offenders living with, or at high risk for contracting HIV in Memphis, Tennessee. During the 5-year evaluation, data were collected from 426 individuals during baseline and 6-month follow-up interviews. A subset of participants (n = 341) completed both interviews.
