Approche méthodologique pour une cartographie du risque de submersion des côtes basses

Cette étude présente une méthode visant à cartographier le risque de submersion des côtes basses en prenant pour exemple deux plages situées dans le Finistère nord. Cette démarche reprend la méthode élaborée par les PPR-L. Toutefois, l'estimation des niveaux d'eau extrêmes a été réalisée en considérant les effets du wave setup. De même, les paramètres dynamiques tels que l'érosion du trait de côte et l'élévation du niveau d'eau pour 2100 ont été pris en compte.
Microwave studies by perturbation of Ag thick film microstrip ring resonator using superstrate of bismuth strontium manganites

Purpose – The purpose of this paper was to determine the complex permittivity of bismuth strontium manganites (Bi1−xSrxMnO3) in the 8‐12 GHz range by using perturbation of Ag thick film microstrip ring resonator (MSRR) due to superstrate of both bulk and thick film.Design/methodology/approach – The BSM ceramics were synthesized by simple low cost solid state reaction method and their fritless thick films were fabricated by screen printing technique on alumina substrate. A comparison has been made between the X band response of Ag thick film microstrip ring resonator due to perturbation of bulk and thick film Bi1−xSrxMnO3 ceramic.Findings – The bulk and thick film superstrate decreases the resonance frequency of MSRR. In this technique even minor change in the properties of superstrate material changes the MSRR response. Variation of strontium content also influences microwave conductivity and penetration depth of bulk and thick films.Originality/value – The microwave complex permittivity decreases with in.
Species composition and richness of the herpetofauna of the semiarid environment of Nordestina, in northeastern Bahia, Brazil

A herpetofauna da Caatinga continua subestimada. A falta de conhecimento levou essa região a ser considerada de baixa riqueza e endemismo. Este estudo tem como objetivo determinar a composição e riqueza de espécies da herpetofauna no município de Nordestina. Os dados foram coletados utilizando diferentes técnicas amostrais, como armadilha de interceptação e queda e procura ativa. A riqueza da herpetofauna foi estimada utilizando o estimador Bootstrap. Além disso, foram calculados também a dominância e equitabilidade por grupo taxonômico. No total, foram registrados 3.969 espécimes distribuídos em 49 espécies. As serpentes apresentaram maior riqueza, enquanto os lagartos foram mais abundantes. Para os anuros, estimou-se, aproximadamente, 14 ± 0,8 espécies, com alta uniformidade (índice de Pielou J’ = 65,8%) e baixa dominância (D = 23,3%), enquanto que, para os répteis, o valor de riqueza estimado foi o mesmo observado, também com alta uniformidade (J’ = 55,7%) e baixa dominância (D = 23,9%). No geral, a área apresenta um padrão de equitabilidade e baixa dominância, o que é uma característica dos ambientes mais conservados e nos leva a destacar a importância desta região para a manutenção da biodiversidade do bioma Caatinga.
Perceived Barriers and Facilitators to Using Knowledge Brokers in Canadian Rehabilitation Settings: A Qualitative Study

Background: Knowledge translation experts advocate for employing knowledge brokers (KBs) to promote the uptake of research evidence in health care settings. However, little is known about factors influencing the utilization of KBs, thereby limiting their employment within healthcare organizations. This research aimed to identify factors likely to hinder or promote the optimal use of KBs within rehabilitation settings in Canada.Methods: Qualitative study using semi-structured telephone interviews with individuals performing KB activities in rehabilitation settings across Canada. The interview topic guide was informed by the Consolidated Framework for Implementation Research (CFIR) and consisted of 20 questions covering five domains (characteristics of individuals, inner setting, process, outer settings, and innovation characteristics). All interviews lasted 60 to 90 minutes, were digitally recorded, and transcribed verbatim. We conducted qualitative descriptive analysis combining deductive coding guided by the CFIR. Two independent analysts coded and rated all interviews, then met to review, deliberate and modify the codes as appropriate. A matrix was created by listing the salient codes for each CFIR construct to identify factors (facilitators and barriers) at the individual, organisational, and process level most likely to impact the KB’s success/failure.Results: Twenty-three participants, from five Canadian provinces were interviewed. At the individual level, the majority of participants reported having strong communication skills, being confident about performing KBs activities, and possessing solid clinical experience and prior research skills. At the organizational level, most respondents indicated constantly networking and engaging with clinical teams and different stakeholders, and having an acceptable level of guidance from their managers. Very few participants felt that they received sufficient organizational support (i.e., clerical support and IT support). At the process level, all participants indicated needing evaluation tools to better gauge their performance, and the majority mentioned that they would benefit from having additional training tailored to their roles as KBs.Conclusions: Individual, organisational and process level factors likely to hinder or promote the optimal use of KBs within Canadian rehabilitation settings include skillsets and networking abilities; culture, resources, and leadership support; and the need for specific training for KBs and for evaluation tools to monitor their performance.
Heterogeneity of Suppliers and Knowledge Transfer in the Supply Chain

This paper empirically studied knowledge transfer between manufacturers and suppliers in the auto manufacturing supply chain. We focused on different suppliers based on merchandise they supplied for auto makers, and analyzed their impact on knowledge transfer in two directions: from manufacturers to suppliers, and from suppliers to manufacturers. Results verified that the former direction of knowledge transfer was significantly impacted by supplier’s roles, but knowledge transfer from suppliers to manufacturers could not be perfectly explained by supplier’s roles. This paper theoretically links suppliers’ role with knowledge transfer between auto makers and suppliers, and the results can assist firms choosing right knowledge transfer strategies according to different suppliers’ roles.
Research on Hydraulic Characteristics of Cutthroat Flume in Irrigation District

In the background of the cutthroat flume of the second stem II station in the Ye River hub of Shijiazhuang, the model test is selected to analyse the hydraulic characteristics of the cutthroat flume. The results show that: (1) The influencing factors on the discharge coefficient in the calculating formula for flow deduced by theory are drawn, the discharge coefficient of the free outflow is relevant to the head above weir and the height of weir, and that of the submerged outflow has relevance to the height of weir and the upstream and downstream water level; (2) the critical condition for the submergence of cutthroat flume is determined, when the ratio of the water depth in the downstream and upstream is less than 0.76, the flow is free outflow, otherwise it is submerged outflow; (3) Based on the regression analysis, the empirical formula of discharge coefficient for the free outflow and submerged outflow are obtained, and the precision is proved to be reasonable by the error analysis.
Shear resistance evaluation of prestressed concrete bridge beams: fib Model Code 2010 guidelines for level IV approximations

The design shear resistance of an existing structure can be evaluated with analytical design procedures and numerical procedures provided by non‐linear finite element analyses. The new fib Model Code 2010 proposes different calculation methods that fall into four different levels of approximation. As the level of approximation rises, so the complexity and the accuracy of the calculated shear resistance increases. Non‐linear finite element analyses belong to the highest level of approximation, but although they are more and more becoming a customary tool in the daily design process, building codes do not provide guidance on how to perform these analyses.

A method for the hierarchical planning of the structure, dimension and material requirements of manufacturing systems

Growing competition creates pressure among companies to run their production in a cost-optimal way and yet adapt immediately to changes in their environmental conditions. Decisions must always consider the integration of the companies in globalised markets on both the demand and supply side. This paper deals with the optimal planning of decisions concerning the structure and dimension of production facilities. The methods used for material requirements planning are selected and configured according to these decisions. These decision problems are represented in the form of four hierarchically layered partial models, each of them realised and iteratively solved by a mathematical optimisation model. The hierarchical planning method is evaluated using a practical case example based on a valve production system of a manufacturing company.

Analysis of Critical Success Factors for Entertainment Tourism Destinations: The Supply Perspective

ABSTRACT Determining the critical success factors is common in tourism research because it can bring many benefits to the tourism industry. Related research is mainly concentrated in accommodation, events, ecotourism, catering, travel agencies, wine tourism, urban tourism, and business tourism. Entertainment tourism is becoming increasingly popular. However, research on the critical success factors of entertainment tourism destination has been overlooked. This study examined these factors from the supply-side perspective with the aim to discover the critical success factors of entertainment tourism in Macau using qualitative research method. The data is collected from managers in the entertainment tourism industry. Eight CSFs, with a total of 21 sub-factors from data collected from semi-structured interviews are observed. These CSFs are product, financial and economic support, service quality, planning and policy, facility and transportation, marketing, human resources and security. The result also indicates the strength of these identified factors in improving and sustaining the development of entertainment tourism. Furthermore, the implications of the success of such development are suggested.
The Complete Plastid Genomes of Seven Sargassaceae Species and Their Phylogenetic Analysis

Sargassum is one of the most important genera of the family Sargassaceae in brown algae and is used to produce carrageenan, mannitol, iodine, and other economic substances. Here, seven complete plastid genomes of Sargassum ilicifolium var. conduplicatum, S. graminifolium, S. phyllocystum, S. muticum, S. feldmannii, S. mcclurei, and S. henslowianum were assembled using next-generation sequencing. The sizes of the seven circular genomes ranged from 124,258 to 124,563 bp, with two inverted regions and the same set of plastid genes, including 139 protein-coding genes (PCGs), 28 transfer (t)RNAs, and 6 ribosomal (r)RNAs. Compared with the other five available plastid genomes of Fucales, 136 PCGs were conserved, with two common ones shared with Coccophora langsdorfii, and one with S. fusiforme and S. horneri. The co-linear analysis identified two inversions of trnC(gca) and trnN(gtt) in ten Sargassum species, against S. horneri and C. langsdorfii. The phylogenetic analysis based on the plastid genomes of 55 brown algae (Phaeophyceae) showed four clades, whose ancient ancestor lived around 201.42 million years ago (Mya), and the internal evolutionary branches in Fucales started to be formed 92.52 Mya, while Sargassum species were divided into two subclades 14.33 Mya. Our novel plastid genomes provided evidence for the speciation of brown algae and plastid genomic evolution events.
Investigation of supercapacitor terminal behavior for power electronics applications

The paper treats an experimental study of supercapacitors for power electronics applications. When designing a supercapacitor-based power system, the terminal behavior of supercapacitor and voltage balancing strategy are two important factors to be considered. In order to study this, a test bench based on HP-VEE has been built firstly. Then, measurements on supercapacitor's capacitance, ESR (Equivalent serial resistance) and the consistency of a group of serial supercapacitors, concerning practical application have been suggested. As an example, Maxwell's BCAP0120 supercapacitors have been selected for a 1.5kW hybrid supercapacitor- fuel cell power system. Tests have been carried out and the results show that the ESR is higher and the capacitance is lower compared with the values supplied by manufacturers; and the consistency of them is good, thus the voltage initialization strategy can be used for voltage balancing.
Multi-Modal Deep Learning for Weeds Detection in Wheat Field Based on RGB-D Images

Single-modal images carry limited information for features representation, and RGB images fail to detect grass weeds in wheat fields because of their similarity to wheat in shape. We propose a framework based on multi-modal information fusion for accurate detection of weeds in wheat fields in a natural environment, overcoming the limitation of single modality in weeds detection. Firstly, we recode the single-channel depth image into a new three-channel image like the structure of RGB image, which is suitable for feature extraction of convolutional neural network (CNN). Secondly, the multi-scale object detection is realized by fusing the feature maps output by different convolutional layers. The three-channel network structure is designed to take into account the independence of RGB and depth information, respectively, and the complementarity of multi-modal information, and the integrated learning is carried out by weight allocation at the decision level to realize the effective fusion of multi-modal information. The experimental results show that compared with the weed detection method based on RGB image, the accuracy of our method is significantly improved. Experiments with integrated learning shows that mean average precision (mAP) of 36.1% for grass weeds and 42.9% for broad-leaf weeds, and the overall detection precision, as indicated by intersection over ground truth (IoG), is 89.3%, with weights of RGB and depth images at α = 0.4 and β = 0.3. The results suggest that our methods can accurately detect the dominant species of weeds in wheat fields, and that multi-modal fusion can effectively improve object detection performance.
Socio-Demographic Variables, Fear of COVID-19, Anxiety, and Depression: Prevalence, Relationships and Explanatory Model in the General Population of Seven Latin American Countries

The COVID-19 pandemic has gravely impacted Latin America. A model was tested that evaluated the contribution of socio-demographic factors and fear of COVID-19 on anxiety and depression in samples of residents in seven Latin American countries (Argentina, Ecuador, Mexico, Paraguay, Uruguay, Colombia, and El Salvador). A total of 4,881 individuals, selected by convenience sampling, participated in the study. Moderate and severe levels of depressive symptoms and anxiety were identified, as well as a moderate average level of fear of COVID-19. In addition, it was observed that about a quarter of the participants presented symptoms of generalized anxiety disorder and a major depressive episode. Fear of COVID-19 significantly and positively predicted anxiety and depressive symptoms, whereas the effects of socio-demographic variables are generally low [χ2(287) = 5936.96, p < 0.001; RMSEA = 0.064 [0.062, 0.065]; CFI = 0.947; and SRMR = 0.050]. This suggests the need for the implementation of preventive actions in the general population of these countries, with the aim of reducing the prevalence of depressive, anxious and fearful symptoms related to COVID-19.
Development of 4 K pulse tube cryorefrigerators at cryomech

Cryomech, Inc. has continued the development of two-stage 4 K pulse tube cryorefrigerators. To address the concerns of customers with vibration levels due to the stretching in the tubes, a vibration elimination apparatus reduced the maximum displacement from 25 μm to <3 μm. The PT405, 0.5 W @4 K, was modified into a model PT407, by using the CP970 Compressor Package increasing the input power from 4.7 to 7.2 kW. It provides 0.72 W @4.2 K with 34 W @55 K. A new 4 K model, PT410, has been developed with cooling capacities of 0.83 W @4.2 K with 38 W @45 K for 8.0 kW power input. The PT410 is driven by one CP970 Compressor Package. With changing the flow impedances, the PT410 also can provide 1.05 W @4.2 K and simultaneously 28 W @56 K again for 8.0 kW of input power.
Control of Magnetopause Flux Rope Topology by Non-local Reconnection

Dayside magnetic reconnection between the interplanetary magnetic field and the Earth’s magnetic field is the primary mechanism enabling mass and energy entry into the magnetosphere. During favorable solar wind conditions, multiple reconnection X-lines can form on the dayside magnetopause, potentially forming flux ropes. These flux ropes move tailward, but their evolution and fate in the tail is not fully understood. Whilst flux ropes may constitute a class of flux transfer events, the extent to which they add flux to the tail depends on their topology, which can only be measured in situ by satellites providing local observations. Global simulations allow the entire magnetospheric system to be captured at an instant in time, and thus reveal the interconnection between different plasma regions and dynamics on large scales. Using the Gorgon MHD code, we analyze the formation and evolution of flux ropes on the dayside magnetopause during a simulation of a real solar wind event. With a relatively strong solar wind dynamic pressure and southward interplanetary magnetic field, the dayside region becomes very dynamic with evidence of multiple reconnection events. The resulting flux ropes transit around the flank of the magnetosphere before eventually dissipating due to non-local reconnection. This shows that non-local effects may be important in controlling the topology of flux ropes and is a complicating factor in attempts to establish the overall contribution that flux ropes make in the general circulation of magnetic flux through the magnetosphere.
iPSC-Derived Microglia as a Model to Study Inflammation in Idiopathic Parkinson’s Disease

Parkinson’s disease (PD) is a neurodegenerative disease with unknown cause in the majority of patients, who are therefore considered “idiopathic” (IPD). PD predominantly affects dopaminergic neurons in the substantia nigra pars compacta (SNpc), yet the pathology is not limited to this cell type. Advancing age is considered the main risk factor for the development of IPD and greatly influences the function of microglia, the immune cells of the brain. With increasing age, microglia become dysfunctional and release pro-inflammatory factors into the extracellular space, which promote neuronal cell death. Accordingly, neuroinflammation has also been described as a feature of PD. So far, studies exploring inflammatory pathways in IPD patient samples have primarily focused on blood-derived immune cells or brain sections, but rarely investigated patient microglia in vitro. Accordingly, we decided to explore the contribution of microglia to IPD in a comparative manner using, both, iPSC-derived cultures and postmortem tissue. Our meta-analysis of published RNAseq datasets indicated an upregulation of IL10 and IL1B in nigral tissue from IPD patients. We observed increased expression levels of these cytokines in microglia compared to neurons using our single-cell midbrain atlas. Moreover, IL10 and IL1B were upregulated in IPD compared to control microglia. Next, to validate these findings in vitro, we generated IPD patient microglia from iPSCs using an established differentiation protocol. IPD microglia were more readily primed as indicated by elevated IL1B and IL10 gene expression and higher mRNA and protein levels of NLRP3 after LPS treatment. In addition, IPD microglia had higher phagocytic capacity under basal conditions—a phenotype that was further exacerbated upon stimulation with LPS, suggesting an aberrant microglial function. Our results demonstrate the significance of microglia as the key player in the neuroinflammation process in IPD. While our study highlights the importance of microglia-mediated inflammatory signaling in IPD, further investigations will be needed to explore particular disease mechanisms in these cells.
