Chemical dispersant enhances microbial exopolymer (EPS) production and formation of marine oil/dispersant snow in surface waters of the subarctic northeast Atlantic by Suja, Laura Duran, Chen, Xindi, Summers, Stephen, Paterson, David M., Gutierrez, Tony

“…A notable feature of the Deepwater Horizon oil spill was the unprecedented formation of marine oil snow (MOS) that was observed in large quantities floating on the sea surface and that subsequently sedimented to the seafloor. Whilst the physical and chemical processes involved in MOS formation remain unclear, some studies have shown that extracellular polymeric substances (EPS) play a role in this process. …”

Pollen geochronology from the Atlantic coast of the united states during the last 500 years by Christie, Margaret A., Bernhardt, Christopher E., Parnell, Andrew C., Shaw, Timothy Adam, Khan, Nicole S., Corbett, Dorbett Reide, García-Artola, Ane, Clear, Jennifer, Walker, Jennifer S., Donnelly, Jeffrey P., Hasse, Tobias R., Horton, Benjamin P.

“…Inconsistencies were likely related to the hyperlocality of pollen chronohorizons, mixing of salt marsh sediment, reworking of pollen from nearby tidal flats, misidentification of pollen signals, and inaccuracies in or misinterpretation of other age markers. …”

Human amplification of secondary earthquake hazards through environmental modifications by Hill, Emma M., McCaughey, Jamie W., Switzer, Adam D., Lallemant, David, Wang, Yu, Sathiakumar, Sharadha

“…Anthropogenic climate change and modification of landscapes — such as deforestation, sediment movement, irrigation and sea-level rise — can destabilize natural systems and amplify hazards from earthquake-triggered landslides, liquefaction, tsunami and coastal flooding. …”

Urban site characterization using DAS dark fibers on the MIT campus in Cambridge, Massachusetts by Chang, Hilary, Nakata, Nori

“…The 1D site-response modeling for shear waves suggests that the fundamental resonance frequency is at 0.6 and 1 Hz, with a sediment-to-bedrock amplitude ratio of 6–7. This should be considered in building design to mitigate seismic hazards. …”

Data analysis of local scour around abutment in compound channel by Zhang, Ruixin

“…This model was built using the relative abutment length (L/yf), abutment aspect ratio (Lc/L), flow intensity (uf/uc), abutment shape factor (Ks), flow depth ratio (yf/ym), and relative sediment size (d50/ yf). Overall, comparisons of calculated and observed maximum equilibrium scour depths indicate that the formula is straightforward in composition and shows good credibility in the computation result.…”

Metasomatism of the continental crust and its impact on surface uplift: insights from reactive‐transport modelling by Worthington, JR, Chin, EJ, Palin, RM

“…High-elevation, low-relief continental plateaus are major topographic features and profoundly influence atmospheric circulation, sediment transport and storage, and biodiversity. Although orogenic surface-uplift mechanisms for modern continental plateaus near known plate margins like Tibet are well-characterized, they cannot account for examples in intracontinental settings like the Colorado Plateau. …”

Geochemical and Sr–Nd–Hf isotopic evidence for Cenozoic partial melting of mantle beneath Natanz, Central Iran by Babazadeh, S, D'Antonio, M, Raeisi, D, Furman, T, Santosh, M, Di Renzo, V, Klötzli, U, Choi, SH, Ghalamghash, J, Cottle, JM, Palin, R

“…Combined modelling of trace element and isotopic data suggests that the most mafic Natanz magmas could have formed through ∼5% melting of a source comprising 99% depleted mantle +1% sediment, with the melts modified subsequently by ∼3% contamination by Cadomian upper crustal components. …”

Repurposing nitroxoline to address antibiotic resistance in the production of poultry for consumption by Zhou, Y

Investigating the impact of growth arrest mechanisms on tumour growth and responses to radiotherapy and hyperthermia by Colson, C

“…In each regime, we determine the biological processes that may underpin positive and negative treatment outcomes and assess which treatment (RT, HT or RT + HT) and dosing regimen maximise the reduction in tumour burden. This work enables us to generate a set of hypotheses that may explain some of the widely varying tumour behaviours observed experimentally and clinically.…”

Cytisine versus varenicline for smoking cessation in a primary care setting: a randomized non-inferiority trial by Oreskovic, T, Percac-Lima, S, Ashburner, JM, Tiljak, H, Rifel, J, Klemenc Ketiš, Z, Oreskovic, S

“…Given the much lower cost of cytisine treatment, its lower rate of adverse events, and higher feasibility (but its likely lower effectiveness with the standard dosage regimen), future analyses should assess the cost-effectiveness of the two treatments for health policy considerations.…”

Enhancement of fexural modulus and strength of epoxy nanocomposites with the inclusion of functionalized GNPs using Tween 80 by Wan Ab Halim, Wan Zateel Aqmaer, Junid, Ramli Junid, Sazali, Norazliane, Siregar, Januar Parlaungan, Abd Razak, Jeeferie, Fitriyana, Deni Fajar, Cionita, Tezara, Jaafar, Jamiluddin

“…Characterization of nanoparticles using SEM shows that ARGNPs indicated a softer image representing a thinner layer of graphene stacks compared to T80GNP which has a tangible solid-looking image resulting from the sedimentation during the process of fltration. Elementally, both ARGNPs and T80GNPs were found to contain carbon, oxygen, and sulfur, as indicated by the EDX spectrum, with the C/O ratio for T80GNPs being 34.7% higher than that for ARGNPs, suggesting the adsorption of Tween 80 molecules on the GNPs after functionalization. …”
