Geochemical exploration of rare earth element resources in highland karstic bauxite deposits in the Sierra de Bahoruco, Pedernales Province, Southwestern Dominican Republic.

This study investigates the geochemical characteristics of rare earth elements (REEs) in highland karstic bauxite deposits located in the Sierra de Bahoruco, Pedernales Province, Dominican Republic. These deposits, formed through intense weathering of volcanic material, represent a potentially valuable REE resource for the nation. Surface and subsurface soil samples were analyzed using portable X-ray fluorescence (pXRF) and a NixPro 2 color sensor validated with inductively coupled plasma optical emission spectrometry (ICP-OES).

The needs of informal caregivers of people experiencing dementia as identified on social media.

Objectives: The aims of this study were to 1) categorize and quantify the most frequent concerns of informal caregivers, 2) conduct a thematic analysis on a sample of the posts, and 3) examine a subset of 100 post responses to determine if they are supportive and evidence- based.

Method: For Aims 1 and 2, we used a qualitative descriptive design using content analysis. To address Aim 3, we used a Delphi method in a subset sample of responses to posts to determine if they were supportive or not and evidence-based or not.

The HIP mouse and all of its organs are completely invisible to allogeneic immune cells.

Hypoimmune (HIP) allogeneic cell therapeutics hold the promise to allow off-the-shelf treatments for a broad patient population. Our HIP approach includes the depletion of major histocompatibility complex (MHC) class I and II molecules and the overexpression of Cd47. Here, we report the engineering of HIP mice that stably exhibit the HIP phenotype in all cell types.

Livestock: Public Interface (Exhibition Livestock/Petting Zoo/Agritourism).

The article discusses the importance of biosecurity in exhibitions, shows, and other public livestock venues, such as petting zoos and agritourism sites. It highlights the risks of disease transmission from animals to humans and between animal groups. The document emphasizes the role of veterinarians in developing biosecurity measures and plans, which should be specific to each venue and reviewed regularly.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.
