Humanin Attenuates NMDA-Induced Excitotoxicity by Inhibiting ROS-dependent JNK/p38 MAPK Pathway (open access)

Humanin Attenuates NMDA-Induced Excitotoxicity by Inhibiting ROS-dependent JNK/p38 MAPK Pathway

This article highlights a study aimed to investigate neuroprotective mechanisms of HN. We analyzed intracellular Ca²+ levels, reactive oxygen species (ROS) production, and the MAPKs signal transduction cascade using an in vitro NMDA-mediated excitotoxicity of cortical neurons model.

Preparation and Characterization of 3D Printed PLA-Based Conductive Composites Using Carbonaceous Fillers by Masterbatch Melting Method (open access)

Preparation and Characterization of 3D Printed PLA-Based Conductive Composites Using Carbonaceous Fillers by Masterbatch Melting Method

This article highlights a study aimed at improving the conductivity of polylactic acid (PLA)-based composites by incorporating carbonaceous fillers. The composites with the addition of graphene nanoplatelets (rGO) or multi-walled carbon nanotubes (MWCNTs) were fabricated by the masterbatch melting method in order to improve the dispersion of the two kinds of nano-fillers. The results showed that, with the addition of 9 wt % rGO, the volume electrical resistivity of the composite reached the minimum electrical resistance of 10³ Ω·m, at which point the conductive network in the composites was completely formed.

Modeling and predicting evacuation flows during hurricane Irma (open access)

Modeling and predicting evacuation flows during hurricane Irma

This article proposes a method to model evacuation flows and reveal the patterns of evacuation flows at different spatial scales. First, the authors present a method to characterize evacuation flows at different geographic scales: the state level, considering evacuation flows across southern states affected by Irma; the urban/rural area level, and the county level. Then they demonstrate results on the predictability of evacuation flows in the most affected state, Florida, by using the following environmental factors: the destructive force of the hurricane, the socioeconomic context, and the evacuation policy issued for counties. The results presented in this paper can help decision makers to better understand population evacuation behaviors given certain environmental features, which in turn will aid in the design of efficient and informed preparedness and response strategies.

Factors Associated with Conservation Participation by Local Communities in Gaurishankar Conservation Area Project, Nepal (open access)

Factors Associated with Conservation Participation by Local Communities in Gaurishankar Conservation Area Project, Nepal

This article examines how residents’ natural resource dependency and other social, economic, and access-related variables predict conservation participation.Overall, key findings suggest that conservation participation at Gaurishankar Conservation Area Project (GCAP)—a newly designated mountainous protected area in Nepal— needs to be improved with multiple outreach activities, especially to resource-dependent households.

Making Our Library Spaces More Accessible: Accessible Furniture for Sycamore Library: Final Report (open access)

Making Our Library Spaces More Accessible: Accessible Furniture for Sycamore Library: Final Report

This report details the feedback from library users and staff, collected via a survey of students with disabilities and a separate survey of library employees, highlighted a need for more accessible furniture in library spaces. The project members purchased various selections of library furniture during the grant period, and staff observed and recorded how users engaged with the new furniture. The project outcome details the recorded observations of users interacting with furniture from the team members.
