To accurately reconstruct palaeoenvironmental change through time it is important to determine which rock samples were deposited contemporaneously at different sites or transects, as erroneous correlation may lead to incorrectly inferred processes and rates. To correlate samples, current practice interpolates geological age between datable units along each transect, then temporal signatures observed in geochemical logs are matched between transects. Unfortunately spatiotemporally variable and unknown rates of sedimentary deposition create highly nonlinear space-time transforms, significantly altering apparent geochemical signatures...

A solid-phase extraction, followed by ultra-high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS) analysis was used in the quantitative target approach, with more than 70 validated compounds...

Feminist perspectives on care have demonstrated how capitalism undervalues care work. The Covid-19 pandemic highlighted this further, as systems of production and social reproduction became destabilized globally. In many countries, the formal pandemic response fell short of attending to the daily, fundamental care needs of people living through the crisis, especially those compromised by the socio-economic effects of the pandemic. These needs were often attended to at the community level. This article explores a community-led network of care, known as CANs, that emerged in response to the pandemic in Cape Town...

The collapse of the Soviet Union triggered an escalation of the tuberculosis (TB) epidemic in many post-Soviet countries, including Ukraine. The main reasons for this situation include both the approach to TB care and the concentration of TB cases in prisons. The neoliberal approach to TB care system reform promises the optimization of treatment terms, "dehospitalization" and "despecialization" of the system of care, and a different type of control, established through digital technologies. One such technology is the "e-TB Manager", which was designated as a national TB registry, including in the prison system in 2012...

PURPOSE: The Pelli-Robson and LEA contrast sensitivity charts are commonly used in clinical settings to measure contrast sensitivity. Although the Pelli-Robson chart is considered the gold standard, it is limited by its bulky size. The LEA chart, on the contrary, offers a more practical and portable option that is still reliable. This has led to questions about whether we can predict Pelli-Robson scores based on LEA scores. This study developed a conversion method to help transition from the LEA chart to the Pelli-Robson chart and validate the conversion score...
