Rare earth element (REEs) imprints and provenance of wetland sediments from Oaxaca coast, Mexico.

REEs in wetland sediments from the Oaxaca coast in southern Mexico were used to infer the sources and depositional processes by involving both the geochemical characteristics and geostatistical approaches. Statistically strong positive correlation between REEs confirmed similar origin in all the cores. Light REEs (LREEs) represented >84 % of ΣREE mean concentrations varies between 47.

Addition of microbial consortium to the rice straw biomethanization: effect on specific methanogenic activity, kinetic and bacterial community.

The biomethanization of lignocellulosic wastes remains an inefficient and complex process due to lignin structures that hinder the hydrolysis step, therefore, some treatments are required. This work describes the addition of an enriched microbial consortium in the biomethanization of rice straw. The experiment was carried out in lab batch reactors following two strategies: (i) pretreatment of rice straw for 48 h using the enriched microbial consortium (dilution 1:100), and (ii) addition of this enriched microbial consortium (dilution 1:100) directly to the anaerobic reactors (bioaugmentation).

Prenatal visualization of the fetal uterus in routine 2D ultrasound examination.

Objective: To establish a new technique to easily identify the fetal cervix-uterus complex in normal female fetuses from 20 to 40 weeks of gestation.

Material And Methods: The study was performed in routine examination in normal fetuses by two observers. Twenty-five consecutive cases per gestational week were assessed between 20 and 40 weeks.

Unlocking advanced thermometric capabilities: BiVO: Er/Yb nanophosphors with dual-mode up-conversion and down-shifting features.

Luminescent materials doped with rare-earth (RE) ions have emerged as powerful tools in thermometry, offering high sensitivity and accuracy. However, challenges remain, particularly in maintaining efficient luminescence at elevated temperatures. This study investigates the thermometric properties of BiVO: Yb/Er (BVO: Er/Yb) nanophosphors synthesized the sol-gel method.

Baseline Characteristics of Self-Determination Theory Constructs and Accelerometer-Derived Physical Activity: The Exercise Promotion in Primary Care (EPPC) Trial.

Background: Health behavior change theories provide a conceptual basis to promote physical activity, one of which is the Self-Determination Theory (SDT). This cross-sectional study compared SDT constructs, specifically exercise goal setting, exercise planning, and outcome expectations, with objectively assessed Moderate-To-Vigorous Physical Activity (MVPA) among a demographically diverse cohort of adults.

Methods: Participants were 18 to 74 years with prediabetes or type 2 diabetes not prescribed insulin and were physically inactive by self-report.
