... All core depths from IODP Expedition 391 were calculated and presented on the core depth below seafloor, Method A (CSF-A) scale (W. Sager et al., 2023a). Penetrated sediment cover ranged from 155 to 380 m in thickness, with Site U1576 having the thickest sediment cover and U1577, the least. ...

... The occurrence of possible winnowed foraminifera sand at the top of the unit may indicate that the absence of Eocene and younger sediment at Site U1577 is related to a phase of erosion (or nondeposition), perhaps in response to the impingement of bottom currents. Interestingly, the same mechanism could account for the possible early Miocene and Oligocene-Maastrichtian hiatuses at Site U1575, which occur above similar foraminifera sand deposits (see Lithostratigraphy in the Site U1575 chapter [Sager et al., 2023b]). Unit II is a ~24 m thick succession of slightly to heavily burrowed pinkish brown to pale brown clayey nannofossil ooze to chalk (Lithofacies 1) with minor interbeds of brown to gray volcanic ash to tuff (Lithofacies 2) ( Figure F12B). ...

... Cyclical sedimentation in the subunit resembles that observed in the overlying units and in Units II-IV at Site U1576, and it likely represents similar cyclical changes in environmental conditions in the Late Cretaceous. The return to reddish brown chalk deposition (i.e., oxic conditions on the seafloor) in Subunit IIIC at Site U1577, following a possible period of anoxia in overlying Subunit IIIB, was not observed at Site U1576 (see Lithostratigraphy in the Site U1576 chapter [Sager et al., 2023c]). This might reflect preservation of slightly older sediments at Site U1577 (i.e., not observed at Site U1576) or spatial variability in oxic versus anoxic ocean bottom (?) conditions around Valdivia Bank during the early Campanian. ...

... Valdivia Bank (VB) is an oceanic plateau in the South Atlantic, part of Walvis Ridge, formed by hotspot-ridge interaction during the Late Cretaceous (∼85 Ma) offshore of Namibia (Figure 1; O'Connor & Duncan, 1990; Thoram et al., 2023). Oceanic plateaus are broad submarine mountains that rise several kilometers above the adjacent ocean floor and have rounded or flat summits, often capped with thick sediments. ...

... Overall, the architecture and magnetic properties of MMNPs are closely linked to their synthesis process [56,57]. Tomography [58], scattering experiments [59,60], and the FORC (first order reversal curves) diagram method [61][62][63], among others, are of significant aid for a detailed analysis of internal structure. ...

... In northern Chinese cities like Lanzhou, Baoji, and Beijing, which belong to the temperate monsoon climate zone and monsoon fringe zone, characterized by distinct seasons, hot and rainy summers, and cold and dry winters, the main dust-retaining tree species for traffic roads are Juniperus formosana, Sophora japonica, Buxus sinica, and Pinus bungeana (Chen et al., 2019;Jun-Hui et al., 2020;Song et al., 2015;Wang et al., 2013;Zhang et al. 2020). Southern Chinese cities like Nanjing, Wuhan, and Jinhua, belonging to the subtropical humid climate zone (monsoon zone), characterized by hot and rainy summers and mild and humid winters, with subtropical evergreen broadleaf forests as the vegetation type, have Magnolia grandiflora, Osmanthus, and Loropetalum chinense as the main dust-retaining tree species in traffic areas (Chen et al., 2015;Wang et al., 2017a, b (Préndez et al., 2023). In general, the leaves of preferred tree species generally have larger surface areas and complex surface structures, such as trichomes and wax layers which help capture and retain airborne particles. ...

... The objective of the research is to analyse how ventilation affected student health,but searching the articles from 2019 till May 2023 informed that some papers just analysed the school's ventilation and indoor air quality in school without continuing how it affects student health. The research only analysed the ventilation and indoor air quality in classrooms, not continuing to how it affects students' health 23,[25][26][27][28][29][30][31][32][33][34] . The others analyse the ventilation and the health effects [35][36][37][38][39] and non-health effects 32,[40][41][42][43][44] , and also the research about indoor air quality and health students 45 ( Figure 3). ...
