Bimetallic catalyst system for the degradation of PCBs in sediments.

In this paper, we report the successful application of a patent-pending reduced bimetallic nanoparticle catalytic system developed for the remediation of polychlorinated biphenyl (PCB)-contaminated sediment and aquatic media. The formation of bimetallic nanoparticles associated with the granular activated carbon (GAC) were confirmed by high-resolution transmission electron microscopy. X-ray photoelectron spectroscopy showed the presence of the bimetallic matrix in reduced, albeit mixed, states.

Interactions between corticotropin releasing factor signaling and prophylactic antibiotics on measures of intestinal function in weaned and transported pigs.

The study objective was to evaluate the interaction between corticotrophin releasing factor () receptor signaling and prophylactic antibiotic administration on intestinal physiology in newly weaned and transported pigs. Pigs (n = 56; 5.70 ± 1.

Investigating the effects of jute nesting material and enriched piglet mats on sow welfare and piglet survival.

Domesticated sows are motivated to perform nesting behavior prior to farrowing, and nesting material can reduce piglet cold stress. However, nesting material may not be practical in most production systems due to the potential for clogging slurry systems. Therefore, the study objectives were to assess an alternative nesting material provided prior to farrowing on sow welfare and piglet survival, and to investigate the effect of the entire nesting environment on piglet survival and growth performance.

The Impact of a Virtual Tobacco Prevention and Advocacy Training Among Youth in Appalachian Kentucky Communities.

Background: Engaging youth is an important component of comprehensive tobacco control programs.

Purpose: This paper describes the impact of a virtual tobacco prevention training program to encourage and prepare youth in Appalachia to support tobacco prevention policies, to strengthen interpersonal confidence to address tobacco use within their communities and enhance advocacy self-efficacy for tobacco control.

Methods: A two-part evidence-informed peer-led tobacco prevention and advocacy training was implemented among 16 high school students from Appalachian counties in Kentucky.

A behavior and physiology-based decision support tool to predict thermal comfort and stress in non-pregnant, mid-gestation, and late-gestation sows.

Background: Although thermal indices have been proposed for swine, none to our knowledge differentiate by reproductive stage or predict thermal comfort using behavioral and physiological data. The study objective was to develop a behavior and physiology-based decision support tool to predict thermal comfort and stress in multiparous (3.28 ± 0.
