Applying trace element geochemistry of archaeological bone to study the coevolution of environmental change and human health in the Roman Empire.

Technological change has affected human health dating back to at least the Neolithic agricultural revolution. Growing evidence indicates widespread environmental pollution began with metallurgical practices and continues today. Environmental exposures to trace elements released from these practices have the potential to alter human body composition, such as bone mineral chemistry, especially for elements that are not homeostatically regulated.

Surgical Management of Complicated Thoracic Fungal Infections: A Case Series from a Tertiary Referral Center.

Although rare in the general population, pulmonary fungal infections usually occur in immunocompromised patients. The mainstay of pulmonary fungal infection treatment is prolonged intravenous antifungal therapy. However, surgical management may be required in cases of complex disease, resistance to medical therapy or percutaneous procedures, or associated complications such as fungal empyema and massive hemoptysis.

Conceptual design of a Doppler spectrometer for 102 m/s cross-field flows in tokamak divertors.

The cross-field transport in the scrape-off-layers (SOLs) and divertors in tokamaks is of a similar size to the poloidal component of the parallel flow, thereby significantly impacting the plasma transport there. However, its direct observation has been challenging because the drift velocity (102-103 m/s) is significantly below the detection limit of conventional diagnostics. To realize cross-field ion flow measurement, a variety of systematic uncertainties in the system must be narrowed down.

Impact of statutory revisions to family-petitioned civil commitment in South Korea.

Introduction: This study examined the impact of statutory revisions in 2016 which aimed to enhance procedural justice within the process of civil commitment for persons diagnosed with mental illnesses (PDMI) in South Korea. These changes included requiring that PDMI pose a threat of danger to self or others and the need for treatment simultaneously as criteria for petitioning civil commitment. Additionally, the revision established a public entity to oversee the legitimacy of petitions to involuntarily commit PDMI to inpatient treatment.
