Room and Elevated Temperature Sliding Friction and Wear Behavior of Al0.3CoFeCrNi and Al0.3CuFeCrNi2 High Entropy Alloys (open access)

Room and Elevated Temperature Sliding Friction and Wear Behavior of Al0.3CoFeCrNi and Al0.3CuFeCrNi2 High Entropy Alloys

Article discusses how, in this study, processing–structure–property relations were systematically investigated at room and elevated temperatures for two FCC Al0.3CoFeCrNi and Al0.3CuFeCrNi2 high-entropy alloys (HEAs), also known as complex concentrated alloys (CCAs), prepared by conventional arc-melting. It was determined that both alloys exhibit FCC single-phase solid solution structure. Micro-indentation and sliding wear tests were performed to study the hardness and tribological behavior and mechanisms at room and elevated temperatures.

Status of Historically Black College and University (HBCU) Archives (open access)

Status of Historically Black College and University (HBCU) Archives

This paper explores the role of Historically Black College and University (HBCU) archives in preserving the history and cultural heritage of these institutions and investigates the factors that contribute to the disparities observed in the availability of digital collections and the staffing of archivists across HBCUs in the United States. Data was collected from 102 HBCU websites and the National Center for Education Statistics, and analyzed using descriptive statistics, chi-square tests, and ordinary linear regression. The findings revealed notable disparities in the staffing of archivists and the presence of digital archive collections, with geography, enrollment, and endowment emerging as potentially significant factors. The study highlights the importance of understanding key factors in the availability of digital archive collections and the staffing of archivists at HBCUs.

Exposure to diesel exhaust particulates and desert sand dust generates microvesicle particles and platelet-activating factor agonists (open access)

Exposure to diesel exhaust particulates and desert sand dust generates microvesicle particles and platelet-activating factor agonists

The authors address the editor in their article, stating that the majority of the general population, particularly, servicemen and women deployed across the globe are exposed to various airborne hazards, including diesel exhaust particulate (DEP) and desert sand dust (DSD). Studies, including the author's study, have shown that exposure to ROS-generating pro-oxidative stressors ranging from environmental carcinogens to pollutants, including cigarette smoke, produces a class of potent phospholipid mediators, Platelet-activating factor (PAF) and PAF-like agonists via oxidative cleavage of lipid membrane glycerophosphocholines (GPCs).

Shedding New Light on Weak Emission-Line Quasars in the CIV-Hβ Parameter Space (open access)

Shedding New Light on Weak Emission-Line Quasars in the CIV-Hβ Parameter Space

Article describes how weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak Lyα+N V λ1240 and/or C IV λ1549 emission lines. The authors investigate the relationship between emission-line properties and accretion rate for a sample of 230 `ordinary' Type 1 quasars and 18 WLQs at z<0.5 and 1.5<z<3.5 that have rest-frame ultraviolet and optical spectral measurements.

Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America

Article describes how, since the mid-20th century, the so-called Great Acceleration has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity. The authors examine cultural practices and socio-environmental changes across four contrasting ethnolinguistic communities in southwestern South America, from southern to northern Chile along a marked climatic gradient to show the broad application of the concept of biocultural calendars.
