Modern periglacial eolian deposits and landforms in the Søndre Strømfjord area, West Greenland and their palaeoenvironmental implications
Authors: Dijkmans Jos W. A. , Törnqvist Torbjörm E. 
Published: November 2023

Modern fluvio glacial sediments in two east-west oriented valleys between Søndre Strømfjord Air Base and the Inland Ice (West Greenland) are partly redeposited by eolian activity. Topographic barriers have induced an areal distinction between sandy and silty eolian sediments. Morphological and sedimentological investigations enable a facies analysis of these rare, active cold-climate eolian deposits and a comparison with the extensive Pleistocene sand sheets and loess deposits of Europe.
Eolian processes are active throughout the year in a dry cold-climate environment. Accumulation of eolian material on the eolian sand sheets and silt covers mainly takes place in summer, whereas deflation and redeposition is dominant in winter. Meteorological conditions (especially thickness of snow cover) may prevent eolian activity.
The vegetation on the sand sheets adapts itself to the intensity of the eolian activity. Vegetation is scarce in the low areas near the active flood plains where deflation is intensive, whereas the downwind depositional areas are more densely vegetated. Only a few species play an active role in the formation of small phytogenic dunes, which are characterized by a low preservation potential. Similar conditions are envisaged for the extensive Pleistocene sand seas of northwestern Europe.
A characteristic sedimentary sequence occurs in downwind, upslope direction. Fluvio-eolian deposits on and near the active flood plain are characterized by horizontally bedded eolian sand interbedded with fluvial deposits. The latter are partly winnowed by eolian activity leading to inversely graded lamination. Horizontal bedding of fine-medium grained sand interbedded with thin coarse-grained strata is the proximal facies of cold-climate eolian sand sheets. Within-bed structures are dominated by plane bed lamination. A more homogeneous (fine-medium grained) horizontally bedded sediment, comparable to that dominating in the extensive Pleistocene sand sheets, represents the distal facies of these sand sheets.
The uplands are covered by eolian silt deposits. These are coarser than 'typical' loess and lack other loess characteristics. This is explained by the local source area and the short transport distance. These 'proximal loess' deposits are mainly deposited on the windward side of the valley walls due to blocking of dust-laden airflows by these topographic barriers. The primary micro-lamination in these deposits may also have been present in the Pleistocene loess deposits.

The 345 m long ice core retrieved from the Hans Tausen Ice Cap in 1995 (82,5°N, 38°W) in Western Peary Land was sampled in situ for later paleoclimatic δ18Omeasurements in Copenhagen.
The upper 125 m covers a little more than 1000 years and indicates strong persistent warming from the late 1920-ties, a maximum warming in the early 1960-ties and a variable climate with no particular trend since the 1960-ties. The δ record over the past 100 years shows similarities with the temperature records from the Greenland west coast stations, Iceland, and the Faroe Islands.
The 20th century is the warmest in the entire record, while the periode 1700-1900 A.D. is the coldest during the past 2000 years. A maximum of warm climate seems to be reached around 900-1100 A.D. which then declines to the colder conditions around 1700 A.D.
The climatic interpretation of the deepest 105 m of the δ record is more complicated due to the non-steady state of the ice cap: The implication for the paleoclimatic interpretation will be discussed. No glacial ice is present in the bottom ice.
Oikonomia et regimen
Authors: Senellart Michel 
Published: November 2023

Cet article propose une réponse à la critique adressée par G. Agamben, dans Le Règne et la Gloire (2008), à la généalogie foucaldienne de la gouvernementalité. En cherchant dans la pensée chrétienne des premiers siècles la matrice d’une conception nouvelle du pouvoir comme gouvernement des hommes — « économie » ou conduite des âmes —, Foucault aurait méconnu la signification proprement théologique, au sein du dispositif trinitaire, du mot oikonomia. Nous voudrions montrer, à partir d’une relecture du 2e Discours (362) de Grégoire de Nazianze (329-390), dont Foucault tire le concept d’une « économie des âmes », que cette idée ne présuppose nullement la référence au schéma trinitaire et renvoie bien davantage au modèle du « patronage » romain, couplé à la figure sacerdotale du bon berger. Cette analyse conduira, en outre, à rappeler le lien de la « direction des âmes » avec le paradigme médical.

Published: November 2023

Background
The pathogenesis of primary spontaneous pneumothorax (PSP) is unclear. Fine particles aggregated in the lung can be phagocytosed by alveolar macrophages (AMs) to induce an inflammatory reaction and damage local pulmonary tissue, which could be a mechanism of PSP. This project aimed to explore the pathological association between fine particulate matter and PSP.

Methods
Thirty pulmonary bullae tissues were obtained from surgery of PSP patients (B group). The adjacent normal tissues of the lungs were defined as the control S group. Another 30 normal lung tissues with nonpneumothorax disease (NPD) were applied as the control N group. Hematoxylin and eosin (H & E), Wright-Giemsa (W-G), Victoria blue, and immunohistochemical (IHC) staining experiments were performed to measure the levels of fine particulate matter, alveolar macrophages (AMs), pulmonary elastic fibers, monocyte chemoattractant protein-1 (MCP-1), and matrix metalloproteinase-9 (MMP-9) in the lung tissues. The serum levels of MCP-1 and MMP-9 were prospectively analyzed as well.

Results
Histopathological examinations revealed obvious deposition of fine particulate matter and inflammatory reactions (proliferation of AMs) in the B group, compared with those in the S group and the N group. These alterations were significantly associated with PSP. The numbers of AMs and pulmonary elastic fibers, the positive area of the H-score, as well as the concentrations of MCP-1 and MMP-9 in the lungs of the experimental group were obviously raised compared with the controls (P < 0.05).

Conclusions
Fine particulate matter aggregation, inflammation (macrophage hyperplasia), and overexpression of MCP-1 and MMP-9 may contribute to the pathogenesis of PSP. The overaccumulation of fine particulate matter may play a crucial part in the occurrence of adolescent and young adult PSP.

Published: November 2023

This study elicits and understands rural youth’s participation in different rural development activities that are being conducted in the Jabalpur district of Madhya Pradesh. Data was collected by using a pre-tested and structured schedule. The demographic composition of youth revealed that majority of them were educated up to higher secondary school, belonged to Other Backward Class (OBC) and had a nuclear family. Majority of them were unmarried and opted farming as their major occupation, had low level of annual income, medium level of use of source of information, achievement motivation, social participation, extension contact and had moderately favorable attitude towards rural development activities. Results revealed that majority (50.00%) of the youth had a medium level of participation in rural development activities. Through NYKS many activities were listed out which were undertaken in respect to rural development. Based on the responses activities were arranged in sequence using the Garett ranking technique to identify and rank which of the following activity is performed regularly and at high extent and vice-versa by the youths. Activities like sanitising village surroundings (Garett score= 65.36), agricultural activities (Garett score=62.51) and plantation (Garett score=61.88) were found to be the major activities performed by the youths.

Published: November 2023

Introduction: Cases of Covid-19 recurrence have become prevalent. This study seeks to establish the level of awareness towards Covid-19 recurrence among adults in Machakos County in Kenya. The study was guided by the health belief model and socio-ecological model.
Methods: The study design was a cross-sectional study. The study adopted a quantitative approach. The target population in this study was 7, 428 Covid-19 patients in Machakos County. The sample size for the study was 418 respondents. Purposive sampling was used in selecting the respondents for the study. Data was collected through a questionnaire.
Data Analysis: Data was analyzed through descriptive statistics comprising of frequencies and percentages. Chi-Square test was used in determining the association between the independent and dependent variables of the study.
Results: From the findings, the overall Covid-19 recurrence was 11.1%. Overall knowledge, attitude and practice levels towards Covid-19 management and control were high. The study found that gender, level of education, engaging in any form of drugs/substance use and abuse and practices towards Covid-19 management and control were the significant host status determinants of Covid-19 recurrence. The study also found that staff shortages, proximity challenges and contaminated hospital environment were the significant facility determinants of Covid-19 recurrence. Further, it was evident from the study that the significant clinical determinants of Covid-19 recurrence included oxygen treatment for Covid-19, and longer duration in hospital during the first Covid-19 infection.
Conclusions and Recommendation: The study recommends that the government should invest more in health facilities in terms of human resource for health personnel and equipment for treatment. The study recommends that future studies should be experimental so as to detect the actual biochemical concentrations for Covid-19 patients and recurrence rates among patients.

ImportanceThere is a clear benefit to body armor against firearms; however, it remains unclear how these vests may influence day-to-day patient encounters when worn by emergency medical services (EMS).ObjectiveTo determine the association of ballistic vests worn by EMS clinicians with workplace violence (WPV) and disparities in care among racial and/or ethnic minority patients.Design, Setting, and ParticipantsProspective cohort study of a volunteer-based sample of EMS clinicians at a large, multistate EMS agency encompassing 15 ground sites across the Midwest from April 1, 2023, to March 31, 2024. Data were analyzed from May to June 2024.ExposureExternal ballistic armor being used by a group of self-selected clinicians on every run.Main Outcomes and MeasuresPrevalence and characteristics associated with WPV and with declines of treatment and/or transport compared between crews with 1 or more vested vs no vested members.ResultsA total of 156 of 415 staff (37.6%) opted in to wear the vests, including 77 male participants (49.4%). Prevalence of WPV was higher for vested crews (1.11 vs 0.85 cases per 100 runs; adjusted risk ratio [aRR], 1.28; 95% CI, 1.10 to 1.50; P = .001) and was due to higher rates of verbal abuse. The presence of 1 or more vested crew members increased the likelihood of all patients declining EMS treatment and/or transport; however, effect size was highest among patients with an unknown race and/or ethnicity (2234 [21.1%] vs 2134 [16.5%] patients; aRR, 1.19; 95% CI, 1.10 to 1.27; P &amp;lt; .001), followed by racial and/or ethnic minority patients (708 [16.7%] vs 399 [13.8%] patients; aRR, 1.18; 95% CI, 1.05 to 1.33; P = .01). Analyses of individual minority groups revealed a significant increase only in Black or African American patients declining treatment and/or transport by vested crews (461 [17.6%] vs 223 [13.7%] patients; RR, 1.28; 95% CI, 1.10 to 1.49; P = .002).Conclusions and RelevanceIn this cohort study, vested crews experienced increased prevalence of WPV compared with nonvested crews. Use of vests increased the frequency of all patients declining EMS treatment and/or transport. Among minority groups, there was a significant increase in Black or African American patients declining treatment and/or transport. Agencies should consider benefits and unintended consequences of EMS clinicians wearing body armor.

ImportanceSensitivity to environmental stress and adversity may influence lung cancer risk, highlighting a critical link between psychosocial factors and cancer etiology.ObjectiveTo evaluate whether genetically estimated sensitivity to environmental stress and adversity is associated with lung cancer risk.Design, Setting, and ParticipantsData were obtained from a genome-wide association study identifying 37 independent genetic variants strongly associated with sensitivity to environmental stress and adversity and a cross-ancestry genome-wide meta-analysis from the International Lung Cancer Consortium. Data were extracted between October 2023 and January 2024 and analyzed between February 2024 and June 2024.ExposuresGenetically estimated sensitivity to environmental stress and adversity.Main Outcomes and MeasuresThe main outcome was lung cancer risk, and odds ratios and 95% CIs were used to assess the association between sensitivity to environmental stress and adversity with lung cancer risk. This genetic association study used a 2-sample Mendelian randomization (MR) to estimate the association between genetically estimated sensitivity to environmental stress and adversity and lung cancer risk across different histologic types.ResultsUsing data from 351 827 individuals from the UK Biobank and a cross-ancestry genome-wide analysis of 61 047 lung cancer cases and 947 237 controls from the International Lung Cancer Consortium, sensitivity to environmental stress and adversity was significantly associated with an increased risk of lung cancer among individuals of European ancestry (OR, 1.49; 95% CI, 1.13-1.98; P = .005) and in the cross-ancestry analysis (OR, 1.45; 95% CI, 1.13-1.85; P = .004). There were heterogeneities in the observed associations across histologic subtypes among different population ancestries. Among individuals of European ancestry, a significant association was noted among squamous cell carcinoma (OR, 1.69; 95% CI, 1.06-2.70; P = .03). Among individuals of East Asian ancestry, an increased risk was observed for adenocarcinoma (OR, 2.04; 95% CI, 1.00-4.18; P = .05). Associations were not observed across any of the 3 histologic subtypes among individuals of African ancestry.Conclusions and RelevanceIn this genetic association study, sensitivity to environmental stress and adversity was associated with lung cancer risk. These results underscore the necessity for further research into the nuanced association between psychosocial stress and cancer risk, with a particular focus on diverse populations.

AbstractIn the 5G era, Barium ferrite (BaFe12O19) has a pivotal position in both fundamental research and frontier applications, such as magnetic recording, microwave absorption, and 2D spintronic devices. Currently, BaFe12O19 is hard to achieve a desirable broadband microwave absorption (MA) because of the underutilized magnetic property limited by Snoek limit, though some efforts have been made by improving the dielectric property to enhance microwave attenuation. The structural design of high anisotropy is deemed an efficient strategy to break the intrinsic Snoek limit of BaFe12O19. The high‐anisotropy 2D nanosheets and 1D nanotubes via ordered growth and assembly can elevate magnetic properties and resonance response. Such optimized spatial structure arrangement can realize ultrawide effective absorption bandwidth (EAB) up to 8.7 and 3.0 GHz, respectively, superior to 0 GHz for conventional BaFe12O19 powders. The morphologies and microstructures of BaFe12O19 effectively trigger shape and magnetic anisotropy, which not only breaks the intrinsic Snoek limit to induce magnetic loss‐dominated MA mechanism, but also promotes dielectric‐magnetic cooperative loss via improved magnetoelectric mutual inductance effect in 1D/2D structures. These results allow for the management of magnetic properties and controllable structural designs of BaFe12O19, providing a reliable means toward ultra‐convenient preparation of high‐anisotropy magnetic materials for more frontier applications.

Published: January 2025

AbstractFunctional textiles that inhibit bacterial proliferation while providing advanced moisture and thermal management are increasingly in demand for regulating personal microclimates and enhancing thermal‐wet comfort. However, traditional wet‐processing technologies face challenges in terms of specific functionalities and limited wash durability, accompanied by severe water waste pollution. In this study, a scalable Janus polyethylene terephthalate (PET) fabric comprising a molecular engineering poly(cation‐π)‐based macromolecule (PXDAG) is developed through an ultrasonic‐assisted spray approach. Density functional theory (DFT) calculations reveals the formation of cation‐π and hydrogen interactions between the PXDAG with cationic nitrogen and aromatic PET, synergistically boosting the antibacterial persistence. The obtained fabric exhibits efficient and sustained antibacterial activity against E. coli and S. aureus (>99.99%), even after 30 wash cycles. Furthermore, the Janus fabrics with PXDAG anchored on one side demonstrates a capacity for directional sweat transport, while maintaining a skin temperature 6.0 °C lower than that of the surrounding environment. Further NMR analysis indicates that intermolecular interactions contributed to robust non‐covalent cohesion and effectively dissipated the fracture energy to improve the interfacial fracture threshold. Combined with the advantages of low cost, eco‐friendliness, and safe operation, the design offers promising solutions for applications in comfortable sportswear, health textiles, and thermal wet comfort.

Published: January 2025

AbstractCarbon dioxide (CO₂) electroreduction in aqueous electrolytes is a complex electrochemical process that involves the transfer of multiple electrons and protons, resulting in various reaction pathways and products. A critical step in this process is the dissociation of water, which provides protons and significantly affects *CO hydrogenation pathways, as well as hydrogen evolution. In this study, copper‐based catalysts are modified through in situ polymerization of dopamine to create intimate polymer coatings that regulate the surface water dissociation process. This modification leads to a notable shift in the product distribution of CO₂ electroreduction, from predominantly multicarbon compounds to methane, accompanied with the ratio of CH4/C2+ changing from 0.5 to 1.8. At high current densities, the polymer‐modified catalyst exhibited stable methane production with a Faradaic efficiency of up to 60%. Kinetic isotopic effects, in situ infrared spectroscopy, and theoretical calculations revealed that polydopamine plays a crucial role in altering product selectivity by regulating hydrolysis. This work signifies the importance of polymer‐regulated hydrolysis to steer the electrochemical CO2 reduction pathways.
