Algal Biochar-Metal Nanocomposite Particles Tailor the Hydration Kinetics and Compressive Strength of Portland Cement Paste.

Biochar can improve the mechanical properties of portland cement paste and concrete. In this work, we produced algal biochar-zinc (biochar-Zn) and algal biochar-calcium (biochar-Ca) nanocomposite particles and studied their effect on the hydration kinetics and compressive strength of cement paste. Results show that 3 wt % biochar-Zn delayed peak heat evolution during cement hydration from 8.

Health equity: A concept analysis.

Background: Although health equity is critically important for healthcare delivery, there are inconsistencies in its definitions or lack of definitions.

Purpose: Develop a comprehensive understanding of health equity to guide nursing practice and healthcare policy.

Method: Walker and Avant's concept analysis method was used to establish defining attributes, antecedents, consequences, and empirical referents of health equity.

Predictable Changes in Eelgrass Microbiomes with Increasing Wasting Disease Prevalence across 23° Latitude in the Northeastern Pacific.

Predicting outcomes of marine disease outbreaks presents a challenge in the face of both global and local stressors. Host-associated microbiomes may play important roles in disease dynamics but remain understudied in marine ecosystems. Host-pathogen-microbiome interactions can vary across host ranges, gradients of disease, and temperature; studying these relationships may aid our ability to forecast disease dynamics.

The Future Is Big-and Small: Remote Sensing Enables Cross-Scale Comparisons of Microbiome Dynamics and Ecological Consequences.

Coupling remote sensing with microbial omics-based approaches provides a promising new frontier for scientists to scale microbial interactions across space and time. These data-rich, interdisciplinary methods allow us to better understand interactions between microbial communities and their environments and, in turn, their impact on ecosystem structure and function. Here, we highlight current and novel examples of applying remote sensing, machine learning, spatial statistics, and omics data approaches to marine, aquatic, and terrestrial systems.

Relationship Between Burnout and Professional Behaviors and Beliefs Among US Nurses.

Objective: To evaluate the relationship between burnout and professional behaviors and beliefs among US nurses.

Methods: We used data from 2256 nurses who completed a survey that included the Maslach Burnout Inventory and items exploring their professional conduct (documented something they had not done so they could "close out" an encounter in the EHR or part of the assessment not completed, requested continuing education credit for an activity not attended) and beliefs about reporting impaired colleagues.

Results: On multivariable analysis, burnout was independently associated with higher odds of reporting 1 or more unprofessional behaviors in the last year and not believing nurses have a duty to report impairment among colleagues due to substance use or mental health problems.
