Challenges in the use of gross alpha and beta screening in nuclear waste characterisation and land remediation.

Gross alpha & beta measurement is a widely used technique for rapid screening of radionuclide content. The study evaluated the influence of geometry, alpha & beta energy and presence of natural decay chain nuclides on the observed gross alpha & beta response. Measured calibration data were validated using Monte Carlo-based modelling.

TRP120 ubiquitinates tumor suppressor APC to modulate Hippo and Wnt signaling.

chaffeensis: TRP120 is a multifunctional effector that acts as a ligand mimic to activate evolutionary conserved eukaryotic signaling pathways Notch, Wnt, Hedgehog and Hippo. In addition, TRP120 is also a HECT E3 ubiquitin ligase known to ubiquitinate several host cell regulatory proteins (FBW7, PCGF5 and ENO-1) for degradation. We previously determined that TRP120 ubiquitinates the Notch negative regulator, FBW7, to maintain Notch signaling and promote infection.

Nursing students' and educators' perspectives on sustainability and climate change: An integrative review.

Aim: To identify and synthesize research on the awareness, attitudes and action related to sustainability and climate change from the perspective of nursing students and educators globally.

Design: Integrative review.

Methods: The review was guided by Whittemore and Knafl.

Current and emerging technologies for the remediation of difficult-to-measure radionuclides at nuclear sites.

Difficult-to-measure radionuclides (DTMRs), defined by an absence of high energy gamma emissions during decay, are problematic in groundwaters at nuclear sites. DTMRs are common contaminants at many nuclear facilities, with (often) long half-lives and high radiotoxicities within the human body. Effective remediation is, therefore, essential if nuclear site end-state targets are to be met.

A comparison of different approaches for the analysis of Cl in graphite samples.

This study compares different approaches for the quantification of the massic activity of Cl in graphite samples. All approaches consisted of a combustion step in combination with a trapping solution to collect the volatile elements. Two different resins were used to separate Cl from the matrix (CL resin and PS resin).
