Caractérisation expérimentale et modélisation micro-mécanique de la perméabilité et la résistance de roches argileuses

Ce memoire s'interesse aux proprietes de transfert, de resistance et de plasticite de roches argileuses. Deux enjeux industriels directs sont la determination du potentiel de production de gaz naturel des roches meres et de la capacite de retention des roches de couvertures utilisees pour les stockages de gaz ou de dechets en milieu souterrain. Dans un premier temps, la permeabilite est decrite comme resultant de l'homogeneisation de l'ecoulement d'un fluide visqueux dans le reseau poreux. Un cadre variationnel analogue a celui de Hashin et Shtrikman en elasticite est etabli et mis a profit pour proposer une methode numerique basee sur la Transformee de Fourier Rapide (FFT) pour le calcul efficace de bornes sur la permeabilite a partir de representations tridimensionnelles voxelisees de milieux poreux. Par ailleurs, des techniques d'homogeneisation analytiques basees sur la definition de cellules permeables equivalentes sont proposees pour fournir des briques elementaires pour la modelisation micro-mecanique de la permeabilite.Le phenomene de glissement du gaz aux parois est considere pour rendre compte quantitativement d'effets du type Klinkenberg sur la permeabilite au gaz. L'effet d'une saturation partielle du reseau poreux sur la permeabilite et la pression de percee sont etudies dans le cas de morphologies particulieres des pores. En parallele, une campagne experimentale est conduite sur differentes roches argileuses issues de forages pour caracteriser leur porosite et leur permeabilite sous diverses conditions de confinement mecanique et desaturation partielle en eau. Dans un second temps, les capacites de resistance sont etudiees sous hypothese de rupture ductile. Une methode numerique efficace basee sur la FFT est proposee pour encadrer par l'exterieur le domaine de resistance de milieux heterogenes a geometrie complexe. D'autre part, une modelisation analytique a trois echelles de la resistance d'un materiau granulaire renforce par inclusions rigides avec interfaces imparfaites est presentee. Enfin, une relecture elasto-plastique de ce modele de resistance a abouti a un modele purement micro-mecanique, dont l'interpretation macroscopique est analogue au modele Cam-clay, avec ecrouissage par changement de porosite et ligne d'etats critiques
Designing a Diving Protocol for Thermocline Identification Using Dive Computers in Marine Citizen Science

Dive computers have an important potential for citizen science projects where recreational SCUBA divers can upload the depth temperature profile and the geolocation of the dive to a central database which may provide useful information about the subsurface temperature of the oceans. However, their accuracy may not be adequate and needs to be evaluated. The aim of this study is to assess the accuracy and precision of dive computers and provide guidelines in order to enable their contribution to citizen science projects. Twenty-two dive computers were evaluated during real ocean dives for consistency and scatter in the first phase. In the second phase, the dive computers were immersed in sufficient depth to initiate the dive record inside a precisely controlled sea aquarium while using a calibrated device as a reference. Results indicate that the dive computers do not have the accuracy required for monitoring temperature changes in the oceans, however, they can be used to detect thermoclines if the users follow a specific protocol with specific dive computers. This study enabled the authors to define this protocol based on the results of immersion in two different sea aquarium tanks set to two different temperatures in order to simulate the conditions of a thermocline.
New Indices for the Existing City-Centers Streets Network Reliability and Availability Assessment in Earthquake Emergency

ABSTRACT During earthquake emergencies in existing city-centers, streets network permits inhabitants to reach safe areas, and rescuers to access damaged zones and help population. However, the network can suffer from blocks due to debris of collapsed or heavily damaged buildings. Understanding urban fabric modifications and classifying elements vulnerability are fundamental steps while dealing with risk-assessment and risk-reduction strategies. This article offers a first quick approach for assessing seismic vulnerability of paths network by considering interferences with building heritage damages. Quick data about existing urban fabric (e.g., buildings typology; streets and buildings geometries) are combined for developing new vulnerability indices for streets network. The earthquake macroseismic intensity is introduced for evaluating probable street blockages and summarizing the overall rating of risks in critical network locations, thus intensity that is not included in other current quick methods for streets-building interference is here taken into account. Risk-reduction strategies based on the proposed indices could minimize the interventions on architectural heritage, maximizing the safety of evacuees. These new indices could be combined with traditional assessment of buildings vulnerability, and evaluations on pedestrians’ and vehicles evacuation flows, for evaluating management strategies.
The Effect of Calcium on Respiration of Apples1

Respiration of apples was inversely related to Ca content of flesh. Respiration increased markedly if Ca concn was below 110 ppm. High N levels also increased respiration. High Ca successfully counteracted the N effect and kept the respiration at a low level. When N was supplied as ammonium, respiration was higher than when a similar quantity of N was supplied as nitrate. Calcium counteracted the increased respiration induced by ammonium-N. Low Ca fruit lost 30-70% of its capacity to synthetize proteins and nucleic acids as measured by the incorporation of labelled valine and uracil. Low-Ca fruit was also high in ethanol insoluble solids, the major portion of which was probably cellulose. The effect of Ca on respiration can explain the negative relation between certain disorders (internal breakdown and watercore) characterized by overmaturity and Ca content of fruit.
Evaluating Different TiO2 Nanoflower-Based Composites for Humidity Detection

Unique three-dimensional (3D) titanium dioxide (TiO2) nanoflowers (TFNA) have shown great potential for humidity sensing applications, due to their large surface area-to-volume ratio and high hydrophilicity. The formation of a composite with other materials could further enhance the performance of this material. In this work, the effect of different types of composites on the performance of a TNFA-based humidity sensor was examined. NiO, ZnO, rGO, and PVDF have been explored as possible composite pairing candidates with TiO2 nanoflowers, which were prepared via a modified solution immersion method. The properties of the composites were examined using field emission electron spectroscopy (FESEM), X-ray diffractometry (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), current-voltage (I-V) analysis, Hall effect measurement, and contact angle measurement. The performance of the humidity sensor was assessed using a humidity sensor measurement system inside a humidity-controlled chamber. Based on the result, the combination of TiO2 with rGO produced the highest sensor response at 39,590%. The achievement is attributed to the increase in the electrical conductivity, hydrophilicity, and specific surface area of the composite.
GmIAA27 Encodes an AUX/IAA Protein Involved in Dwarfing and Multi-Branching in Soybean

Soybean plant height and branching affect plant architecture and yield potential in soybean. In this study, the mutant dmbn was obtained by treating the cultivar Zhongpin 661 with ethylmethane sulfonate. The dmbn mutant plants were shorter and more branched than the wild type. The genetic analysis showed that the mutant trait was controlled by a semi-dominant gene. The candidate gene was fine-mapped to a 91 kb interval on Chromosome 9 by combining BSA-seq and linkage analysis. Sequence analysis revealed that Glyma.09g193000 encoding an Aux/IAA protein (GmIAA27) was mutated from C to T in the second exon of the coding region, resulting to amino acid substitution of proline to leucine. Overexpression of the mutant type of this gene in Arabidopsis thaliana inhibited apical dominance and promoted lateral branch development. Expression analysis of GmIAA27 and auxin response genes revealed that some GH3 genes were induced. GmIAA27 relies on auxin to interact with TIR1, whereas Gmiaa27 cannot interact with TIR1 owing to the mutation in the degron motif. Identification of this unique gene that controls soybean plant height and branch development provides a basis for investigating the mechanisms regulating soybean plant architecture development.
P Waves Emerged From Ambient Noise Cross‐Correlation Post the 2018 Kı̄lauea Eruption Revealing Middle Crust Velocity Discontinuities Beneath the Island of Hawai'i

Empirical Green Functions (EGFs) obtained from ambient noise cross‐correlation are important for imaging and monitoring underground structures. The EGFs on the Island of Hawai'i in different years are similar at low frequencies (0.1–0.4 Hz), but very different at high frequencies (0.4–1.0 Hz): Only the EGFs after the 2018 Kı̄lauea eruption show clear P waves. Grid search reveals a strong noise source near the Kı̄lauea summit before the eruption, which contaminated the EGFs but became silent after the eruption. Modeling of the P waves identifies the direct arrival and post‐critical reflections from two velocity discontinuities at 4.7 and 7.2 km depth beneath the island, which we interpret as the base of volcanic edifices and deposits and the boundary between basaltic dikes and gabbros, respectively. The P waves in EGFs could provide valuable high‐resolution constraints for monitoring deep magmatic changes and imaging the volcano structures.
Exploring the Research Priorities for Occupational Therapy in India: A Descriptive Review

Background: Occupational therapists are considered an important workforce for the rehabilitation of persons with disabilities globally. However, in India, the profession is just beginning to gain recognition within the national and state-level systems for health care. One of the reasons for this could be the paucity of specific research related to the development of occupational therapy (OT) and its benefits to the health systems. Therefore, it is of immense public health importance to explore the priorities and gaps in OT research in India. A vast majority of the OT research in India is promoted and disseminated through the All-India Occupational Therapists Association (AIOTA) and its annual national conference (ANC). Objectives: The objective of this study is to descriptively review the conference abstracts of the AIOTA ANC published in the Indian Journal of OT (IJOT), an official publication of the AIOTA, from 2017 to 2021. Study Design: The study design was a descriptive, nonsystematic review. Methods: Review of the abstracts selected for the AIOTA ANC published in the IJOT from 2017 to 2021. A data extraction form was developed and used to synthesize data related to the clinical and demographic characteristics of OT research in India. Results: The search yielded 218 abstracts. State-level trends indicated that close to 85% of the research submissions were from four states and no submissions from the northeastern states until 2020. Nearly 60% of the abstracts were clinical research with OT interventions. About 40% of these research abstracts were related to pediatrics, followed by neurology (17%), musculoskeletal (15%), mental health (10%), and ergonomics and assistive technology (8%). There were 1%–2% of research abstracts submitted related to coronavirus disease-2019 (COVID-19) and geriatrics. About 85% of the research abstracts were related to impairment (39%), activity limitation (26%), and social participation (22%). Conclusion: This review highlights the need for diversifying the research in OT in India. This is particularly important in relation to expanding from selected states to pan-India research and development, especially in the northeastern states. Furthermore, the focus of OT research must move beyond impairments and approach disability from the biopsychosocial perspective. It is also very important to diversify the research in OT to areas that are of public health importance such as COVID-19, geriatrics, noncommunicable diseases, and rehabilitation in health systems. Priority setting for research in OT in India is an important implication of this review.
Comparative Transcriptome Analysis of Deep-Rooting and Shallow-Rooting Potato (Solanum tuberosum L.) Genotypes under Drought Stress

The selection and breeding of deep rooting and drought-tolerant varieties has become a promising approach for improving the yield and adaptability of potato (Solanum tuberosum L.) in arid and semiarid areas. Therefore, the discovery of root-development-related genes and drought tolerance signaling pathways in potato is important. In this study, we used deep-rooting (C119) and shallow-rooting (C16) potato genotypes, with different levels of drought tolerance, to achieve this objective. Both genotypes were treated with 150 mM mannitol for 0 h (T0), 2 h (T2), 6 h (T6), 12 h (T12), and 24 h (T24), and their root tissues were subjected to comparative transcriptome analysis. A total of 531, 1571, 1247, and 3540 differentially expressed genes (DEGs) in C16 and 1531, 1108, 674, and 4850 DEGs in C119 were identified in T2 vs. T0, T6 vs. T2, T12 vs. T6, and T24 vs. T12 comparisons, respectively. Gene expression analysis indicated that a delay in the onset of drought-induced transcriptional changes in C16 compared with C119. Functional enrichment analysis revealed genotype-specific biological processes involved in drought stress tolerance. The metabolic pathways of plant hormone transduction and MAPK signaling were heavily involved in the resistance of C16 and C119 to drought, while abscisic acid (ABA), ethylene, and salicylic acid signal transduction pathways likely played more important roles in C119 stress responses. Furthermore, genes involved in root cell elongation and division showed differential expression between the two genotypes under drought stress. Overall, this study provides important information for the marker-assisted selection and breeding of drought-tolerant potato genotypes.
Ocular Manifestations in Patients with Inflammatory Bowel Disease in the Biologics Era

Background: Extra-intestinal manifestations are frequent in inflammatory bowel disease (IBD). Ocular disorders are generally under diagnosed as they are challenging diagnosis. Aims: We assessed the prevalence of ophthalmological manifestations in patients with IBD, and investigated characteristics associated with ocular manifestations. Methods: We performed a retrospective study including patients followed for IBD and had an ophthalmologic visit from January 2013 to July 2020, among 1432 patients followed during this period. Two groups were considered: the first group included patients whose an ocular diagnosis was considered as “related to IBD”, and the second group including patients whose an ocular diagnosis was considered “not related to IBD”. Results: Among 1432 patients with IBD, eighty-seven (6.1%) patients had an ophthalmologic visit. Fifty-three patients (3.7%) were considered to have an ocular extra-intestinal manifestation or an iatrogenic effect of IBD treatment, and 34 diagnoses (2.4%) were considered not related to IBD. Inflammatory surface pathologies were the most frequent (33.2%), including 15 patients with dry eye (17.2%), 9 with blepharitis (10.3%), and 5 with chalazions (meibomian cyst) (5.7%). Uveitis was diagnosed in 13 patients (14.9%), episcleritis in 5 patients (5.7%), and scleritis in 2 patients (2.3%). Characteristics of patients with an ophthalmological diagnosis “related to IBD” versus “not related to IBD” were not statistically different. Conclusion: In our cohort, less than 5% of patients had ophthalmological extra-intestinal manifestation. The most frequent ocular diagnosis were dry eye and uveitis. No disease characteristics of IBD were found to be associated with ocular manifestations.
Operator Dictionaries and Wave Functions in AdS/CFT and dS/CFT

Dual AdS/CFT correlators can be computed in two ways: differentiate the bulk partition function with respect to boundary conditions, or extrapolate bulk correlation functions to the boundary. These dictionaries were conjectured to be equivalent by Banks, Douglas, Horowitz, and Martinec. We revisit this question at the level of bulk path integrals, showing that agreement in the presence of interactions requires careful treatment of the renormalization of bulk composite operators. By contrast, we emphasize that proposed dS/CFT analogues of the two dictionaries are inequivalent. Next, we show quite generally that the wave function for Euclidean AdS analytically continues to the dS wave function with Euclidean initial conditions. Most of our arguments consider interacting fields on a fixed background, but in a final section we discuss the inclusion of bulk dynamical gravity.
Intensification Differentially Affects the Delivery of Multiple Ecosystem Services in Subtropical and Temperate Grasslands

Intensification, the process of intensifying land management to enhance agricultural goods, results in “ intensive ” pastures that are planted with productive grasses and fertilized. These intensive pastures provide essential ecosystem services, including forage production for livestock. Understanding the synergies and tradeoffs of pasture intensification on the delivery of services across climatic regions is crucial to shape policies and incentives for better management of natural resources. Here, we investigated how grassland intensification affects key components of provisioning (forage productivity and quality), supporting (plant diversity) and regulating services (CO 2 and CH 4 fluxes) by comparing these services between intensive versus extensive pastures in sub-tropical and temperate pastures in the USDA Long-term Agroecosystem Research (LTAR) Network sites in Florida and Oklahoma, USA over multiple years. Our results suggest that grassland intensification led to a decrease in measured supporting and regulating services, but increased forage productivity in temperate pastures and forage digestibility in subtropical pastures. Intensification decreased the net CO 2 sink of subtropical pastures while it did not affect the sink capacity of temperate pastures; and it also increased environmental CH 4 emissions from subtropical pastures and reduced CH 4 uptake in temperate pastures. Intensification enhanced the global warming potential associated with C fluxes of pastures in both ecoregions. Our study demonstrates that comparisons of agroecosystems in contrasting ecoregions can reveal important drivers of ecosystem services and general or region-specific opportunities and solutions to maintaining agricultural production and reducing environmental footprints. Further LTAR network-scale comparisons of multiple ecosystem services across croplands and
Environment and Planning

You will develop a broad overview of how our towns, cities and regions have developed and have an opportunity to specialise in environmental or urban regeneration issues. You’ll gain a rounded understanding of the factors and forces that are shaping the environment and the role that planning can play in reconciling competing and conflicting interests. Attention is focused on approaches to the protection and enhancement of natural and built environments in a rapidly changing world. An interdisciplinary approach to study provides learning opportunities that draw upon the expertise of academics in Planning as well as academics in the departments of Geography, Sociology and Architecture.
Isolation of Aquatic Plant Growth-Promoting Bacteria for the Floating Plant Duckweed (Lemna minor)

Plant growth-promoting bacteria (PGPB) can exert beneficial growth effects on their host plants. Little is known about the phylogeny and growth-promoting mechanisms of PGPB associated with aquatic plants, although those of terrestrial PGPB have been well-studied. Here, we report four novel aquatic PGPB strains, MRB1–4 (NITE P-01645–P-01648), for duckweed Lemna minor from our rhizobacterial collection isolated from Lythrum anceps. The number of L. minor fronds during 14 days co-culture with the strains MRB1–4 increased by 2.1–3.8-fold, compared with an uninoculated control; the plant biomass and chlorophyll content in co-cultures also increased. Moreover, all strains possessed an indole-3-acetic acid production trait in common with a plant growth-promoting trait of terrestrial PGPB. Phylogenetic analysis showed that three strains, MRB-1, -3, and -4, were affiliated with known proteobacterial genera (Bradyrhizobium and Pelomonas); this report is the first to describe a plant-growth promoting activity of Pelomonas members. The gammaproteobacterial strain MRB2 was suggested to be phylogenetically novel at the genus level. Under microscopic observation, the Pelomonas strain MRB3 was epiphytic and adhered to both the root surfaces and fronds of duckweed. The duckweed PGPB obtained here could serve as a new model for understanding unforeseen mechanisms behind aquatic plant-microbe interactions.
Factors associated with depression among heart failure patients at selected public hospitals in Addis Ababa, Ethiopia: A cross sectional study

This study aimed to Assess Factors associated with depression among heart failure patients at cardiac follow-up clinics in a government teaching hospital of Addis Ababa. A cross-sectional study design was employed to assess Factors associated with depression among 424 heart failure patients at selected public hospitals of Addis Ababa who were selected by using a systematic random sampling method from January 1 to 30, 2021 at four public hospitals. Sample was proportionally allocated for each study hospital and then data were collected by using structured-interview questionnaires. Bivariate and Multivariate logistic regression analysis was done to examine the possible predictors and variables with the statistical association of P-value of < 0.05 and a 95% confidence interval were considered. Data were gathered from heart failure patients in cardiac follow clinic with 100% response rate. Among the 424 respondents [mean age: 52.7 (SD) 17.5 years; 56.1% women], prevalence of depression was 56.1%. Among the 424 respondents [mean age: 52.7 (SD) 17.5 years; 56.1% women], prevalence of depression was 56.1%. New York Heart Association class III and IV was highly associated with depression respectively. Furthermore, poor self-care behaviours alcohol use, poor social support, poor knowledge level, were associated with depression and statistically significant. The findings from this study showed that depression is highly prevalent among heart failure patients and age of respondent, alcohol intake, self-care behaviour, social support, knowledge level, and co-morbidity were independently associated with depression. Therefore, all institutions of cardiac centre should work on screening for depression in heart failure patients, and consult psychiatrists and psychologists for early detection and measures.
