Estimation of the Oil-in-Place Resources in the Liquid-Rich Shale Formations Exploiting Geochemical and Petrophysical Data in a 3D High-Resolution Geological Model Domain: Baltic Basin Case Study
Authors: Sowiżdżał Krzysztof , Słoczyński Tomasz , Kaczmarczyk Weronika
Published: May 2020

The paper discusses the issue of oil-in-place estimation for liquid-saturated shales in Lower Paleozoic (Silurian and Ordovician) organic-rich formations of the Baltic Basin in North Poland. The authors adopted a geochemical method based on Rock Eval results which directly measure hydrocarbon content present in rock samples. Its application on a real data set required the implementation of correction procedures to consider also those oil compounds which were lost before Rock Eval measurements were taken or are not recorded in S1 parameter. It was accomplished through the introduction of two correction coefficients: c1—for evaporation loss and c2—for heavier compounds underestimation. The first one was approximated on the basis of published results and known properties of crude oil, while the second one was addressed with laboratory experimental procedure which combines Rock Eval pyrolysis and rock sample extraction with organic solvents. The calculation formulas were implemented in the 3D geological model of shale formations reproducing their geometry as well as the spatial variability of the petrophysical and geochemical properties. Consequently, the results of oil-in-place estimation were also available as 3D models, ready for visualization and interpretation in terms of delineation of most favorable zones or well placement. The adopted geochemical method and the results of oil-in-place estimation it produced were confronted with standard volumetric method. Although both of them are volumetric methods, the results depend on different sets of rock properties, which is an advantage for result comparison reasons. The study revealed that the geochemical method of oil-in-place estimation in liquid-rich shales after appropriate adjustment, considering shale formation and reservoir fluid dependent conditions, could provide reliable results and be implemented on the early stage of shale exploration process in a condition of production data inaccessibility.

Authors: Xie Kaize , Zhao Weigang , Cai Xiaopei , Wang Ping , Zhao Jia
Published: May 2020

Geometric nonlinearity (GN) and initial internal forces (IIFs) are the basic characteristics of cable-stayed bridges, but now there is no effective method for analyzing the effect of them on bridge-track interaction of continuous welded rail (CWR) on cable-stayed bridge. A method for reconstructing the displacement-force curve of ballast longitudinal resistance was put forward according to the deformation of cable-stayed bridges under the completed bridge state. A feasibility study on the method was conducted via two aspects of the force and deformation of CWR on a 5 × 40 m single-line simple-supported beam bridge with initial deformation. With the multi-element modeling method and the updated Lagrangian formulation method, a rail-beam-cable-tower 3D calculation model considering the GN and IIFs of cable-stayed bridge was established. Taking a (140 + 462 + 1092 + 462 + 140 m) twin-tower cable-stayed bridge as an example, the impacts of GN and IIFs on bridge-track interaction were comparatively analyzed. The results show that the method put forward to reconstruct ballast longitudinal resistance can prevent the impact of initial deformation of bridge and makes it possible to consider the effect of IIFs of cable-stayed bridge on bridge-track interaction. The GN and IIFs play important roles in the calculation of rail longitudinal force due to vertical bending of bridge deck under train load and the variance of cable force due to negative temperature changes in bridge decks and rails with rail breaking, and the two factors can reduce rail longitudinal force and variance of cable force by 11.8% and 14.6%, respectively. The cable-stayed bridge can be simplified as a continuous beam bridge with different constraints at different locations, when rail longitudinal force due to positive temperature changes in bridge deck and train braking is calculated.

Authors: Qin Min , Liu Jiansheng , Li Jingdan
Published: May 2020

The presence of voids in the ingot affects the mechanical properties of the final products of the forging process. It is essential to establish a void closure model to predict cavity closure in the forging process to optimize the forging process and improve forging quality. The main purpose of this study is to obtain an accurate prediction model of void closure for 316LN stainless steel. Using the FEM simulation method to study the closure of spherical voids during forging compression of 316LN materials, we can accurately characterize the state of void closure. The void closure ratio K under different deformations at 1,200°C was counted, and the relationship between K and the effective strain was established to obtain the void closure prediction model of 316LN stainless steel. The void closure prediction model is implanted into DEFORM software through the secondary development method to generate the void closure ratio K. In the postprocessing module of DEFORM software, the void closure status of each part during the forming process can be directly observed. Comparing the results of large‐scale upsetting experiments and simulation results, the closure error of each part was only 3%, which indicates that the void closure model established in this paper has higher accuracy, which is helpful for the optimization of the forging process and the control of forging quality.
Multislope PI Modeling and Feedforward Compensation for Piezoelectric Beam
Authors: Xu Ming , Zhang Jia-qi , Rong Cheng , Ni Jing
Published: May 2020

The hysteresis nonlinearity greatly reduces the tracking precision of piezoceramic actuators for expected displacement in a high-accuracy positioning system. In order to effectively compensate the hysteresis for piezoelectric ceramics, a novel modeling method, namely, multislope PI (Prandtl–Ishlinskii) was proposed. In view of the minimum mean square error (MSE) criterion, the weights of an improved PI model were identified by the quadratic programming optimization algorithm. For verifying the accuracy of the proposed multislope PI hysteresis model, a feedforward compensation control for piezoceramic beam was achieved. The corresponding experimental system was established, and the displacement tracking experiments were carried out. The results indicated that the mean tracking error was 0.2828 μm and within 1% of full scale, as well as the MSE was 0.3100 μm. Compared with the conventional PI model, the proposed multislope PI model demonstrated a significant improvement in positioning performance for the piezoceramic beam.
On a Dual Direct Cosine Simplex Type Algorithm and Its Computational Behavior
Authors: Badr Elsayed , Almotairi Sultan
Published: May 2020

The goal of this paper is to propose a dual version of the direct cosine simplex algorithm (DDCA) for general linear problems. The proposed method has not artificial variables, so it is different from both the two-phase method and big-M method. Our technique solves the dual Klee–Minty problem via two iterations and solves the dual Clausen problem via four iterations. The power of the proposed algorithm is evident from the extensive experimental results on benchmark problems adapted from NETLIB. Preliminary results indicate that this dual direct cosine simplex algorithm (DDCA) reduces the number of iterations of the two-phase method.

Authors: Li Quanrun , Hsu Chingfang , He Debiao , Choo Kim-Kwang Raymond , Gong Peng
Published: May 2020

With the rapid development of quantum computing and quantum information technology, the universal quantum computer will emerge in the near decades with a very high probability and it could break most of the current public key cryptosystems totally. Due to the ability of withstanding the universal quantum computer’s attack, the lattice-based cryptosystems have received lots of attention from both industry and academia. In this paper, we propose an identity-based blind signature scheme using lattice. We also prove that the proposed scheme is provably secure in the random oracle model. The performance analysis shows that the proposed scheme has less mean value of sampling times and smaller signature size than previous schemes. Thus, the proposed scheme is more suitable for practical applications.
Complete Defense Framework to Protect Deep Neural Networks against Adversarial Examples
Authors: Sun Guangling , Su Yuying , Qin Chuan , Xu Wenbo , Lu Xiaofeng , Ceglowski Andrzej
Published: May 2020

Although Deep Neural Networks (DNNs) have achieved great success on various applications, investigations have increasingly shown DNNs to be highly vulnerable when adversarial examples are used as input. Here, we present a comprehensive defense framework to protect DNNs against adversarial examples. First, we present statistical and minor alteration detectors to filter out adversarial examples contaminated by noticeable and unnoticeable perturbations, respectively. Then, we ensemble the detectors, a deep Residual Generative Network (ResGN), and an adversarially trained targeted network, to construct a complete defense framework. In this framework, the ResGN is our previously proposed network which is used to remove adversarial perturbations, and the adversarially trained targeted network is a network that is learned through adversarial training. Specifically, once the detectors determine an input example to be adversarial, it is cleaned by ResGN and then classified by the adversarially trained targeted network; otherwise, it is directly classified by this network. We empirically evaluate the proposed complete defense on ImageNet dataset. The results confirm the robustness against current representative attacking methods including fast gradient sign method, randomized fast gradient sign method, basic iterative method, universal adversarial perturbations, DeepFool method, and Carlini & Wagner method.
Prevalence and Determinants of Rural-Urban Utilization of Skilled Delivery Services in Northern Ghana
Authors: Saaka Mahama , Akuamoah-Boateng Jones
Published: May 2020

Background. There are wide differences in the uptake of skilled delivery services between urban and rural women in the northern region of Ghana. This study assessed the rural-urban differences in the prevalence of and factors associated with uptake of skilled delivery in the northern region of Ghana. Methods. The study population comprised postpartum women who had delivered within the last three months prior to the study. The dataset was analyzed using the chi-square test and multivariable logistic regression. Results. The odds of skilled birth attendance (SBA) adjusted for confounding variables in urban areas were higher compared with their rural counterparts (AOR = 1.59; CI: 1. 07–2.37; p=0.02). The determinants of skilled delivery were similar but of different levels and strength in rural and urban areas. The main drivers that explained the relatively high skilled delivery coverage in the urban areas were higher frequency of antenatal care (ANC) attendance, proximity (physical access) to health facility, and greater proportion of women attaining higher educational level of at least secondary school. Distance from health facility less than 4 km was the greatest independent contributor to the variance in skilled delivery in the urban areas, whereas frequency of ANC attendance was the greatest independent contributor in the rural areas. Conclusions. This study identified underlying determinants accounting for rural-urban differences in skilled delivery, and covariate effect was more dominant than coefficient effect. Therefore, urban-rural differences in SBA outcomes were primarily due to differences in the levels of critical determinants rather than the nature of the determinants themselves. Therefore, improving skilled delivery outcomes in this study population and other similar settings will not require different policy frameworks and interventions in dealing with rural-urban disparities in SBA outcomes. However, context-specific tailored approaches and strategies including targeting mechanisms have to be designed differently to reduce the rural-urban differences.

Published: May 2020

Background

Prior data demonstrate significant heterogeneity regarding coronary artery disease risk factors and outcomes among Asians in the United States, but no studies have yet examined coronary artery disease treatment patterns or outcomes among disaggregated Asian American subgroups.

Methods and Results

From a total of 772 882 patients with known race/ethnicity and sex who received care from a mixed‐payer healthcare organization in Northern California between 2006 and 2015, a retrospective analysis was conducted on 6667 adults with coronary artery disease. Logistic regression was used to examine medical and procedural therapies and outcomes by race/ethnicity, with adjustment for age, sex, income, and baseline comorbidities. Compared with non‐Hispanic whites, Chinese were more likely to undergo stenting (50.9% versus 60.8%, odds ratio [
OR

CI
, 1.04–1.87], p=0.005), whereas Filipinos were more likely to receive bypass surgery (6.9% versus 20.5%,
OR
2.65 [95%
CI
, 1.75–4.01],
P
<0.0001). After stenting, Chinese, Filipinos, and Japanese were more likely than non‐Hispanic whites to be prescribed clopidogrel (86.2%, 83.0%, and 91.4% versus 74.5%,
OR
s 1.86 [95%

CI
, 1.02–18.67], respectively,
P
<0.0001). Lastly, Chinese and Asian Indians were more likely than non‐Hispanic whites to be diagnosed with a myocardial infarction within 1 year postangiography (15.6% and 17.4% versus 11.2%,
OR
s 1.49 [95%
CI
, 1.02–2.19] and 1.68 [95%
CI
, 1.21–2.34], respectively,
P

Conclusions

Disaggregation of Asian Americans with coronary artery disease into individual racial/ethnic subgroups reveals significant variability in treatment patterns and outcomes. Further investigation into these differences may expose important opportunities to mitigate disparities and improve quality of care in this diverse population.
Effects of Flipped Classroom Instruction: Evidence from a Randomized
Trial
Authors: Setren Elizabeth , Greenberg Kyle , Moore Oliver , Yankovich Michael
Published: May 2020

In a flipped classroom, an increasingly popular pedagogical model, students view a video lecture at home and work on exercises with the instructor during class time. Advocates of the flipped classroom claim the practice not only improves student achievement but also ameliorates the achievement gap. We conduct a randomized controlled trial at West Point and find the flipped classroom produced short-term gains in math and no effect in economics. The flipped model broadened the achievement gap: Effects are driven by white, male, and higher-achieving students. We find no long-term average effects on student learning but the widened achievement gap persists. Our findings demonstrate feasibility for the flipped classroom to induce short-term gains in student learning; however, the exacerbation of the achievement gap, the effect fade-out, and the null effects in economics, suggest that educators should exercise caution when considering the model.
David Katz’s “Phenomenological Psychology”
Authors: Giorgi Amedeo
Published: May 2020

David Katz (1884-1953)was an experimental psychologist who worked in the early years of psychology as an independent science. He performed many experiments on color vision and touch by means of what he called the “phenomenological method.” He claimed to have learned the method by attending Husserl’s lectures on phenomenological philosophy while the latter was teaching at Göttingen. However the method that Katz actually used was “description with an attitude of disciplined naiveté”. Consequently, while such a method was known as “phenomenological” at the time Katz was working, the nomenclature reflects a historically dated meaning of phenomenology and not the sense of phenomenological method that Husserl developed later in his career. Katz’s method was actually qualitative and empirical. It was not phenomenological according to Husserl’s complete, mature philosophy.
The Syncretic Revelation of John of Gaza
Authors: Aleksandrova Tatiana
Published: May 2020

This paper suggests that John of Gaza’s poem Tabula Mundi which is in general considered to be an ekphrasis of a real picture that had once adorned winter baths in Gaza or Antioch, actually reflects the author’s personal cosmological beliefs and is an ekphrasis in form only. In the poem there are parallels both with the mystical narratives of the ascent to heaven, and with Christian apocalyptic teachings. However, John of Gaza’s ʻrevelationʼ is not about the end of the world, but about its infinity and wise structure. The form of ekphrasis may have been chosen for the sake of disguise, since in the time when John lived, the views reflected in his poem may have been considered heretical.

Authors: You Miaomiao , Zhang Zulei , Xu Weichang , Lu Chao , Gong Yi , Yang Wei
Published: May 2020

Objective: Lung cancer (LC) remains to be the most frequent cancer among male patients, nonsmall-cell lung cancer (NSCLC) is the most common type of LC. Here we aim to investigate the effect of Pro-b cell clonal enhancer factor (PBEF) on the growth of human NSCLC cells treated
with hypoxia/reoxygenation (H/R). Methods : NSCLC A549 cells were divided into four groups: (1) control group; (2) model group; (3) model+ pCAGGS no-load control group; (4) model+ pCAGGS PBEF group. PCAGGS PBEF plasmid was constructed and transfected into the cells, and the expression of PBEF
was detected by qPCR and WB, H/R model was constructed, western blot (WB) was used to detect the expressions of AQP1 and ENaC , and cell apoptosis was detected by flow cytometry. Results: Cell apoptosis ratio was higher in H/R model group than that of normal control group; there was
no significant difference in apoptosis ratio between the model group and the no-load control group; while the apoptosis ratio in the overexpressed PBEF group was significantly higher than that of the no-load group. AQP1 and ENaC protein levels were significantly lower in the overexpressed
PBEF group than the no-load group, while there was no significant difference among normal control group, the model group and the no-load group. Conclusion: Overexpression of PBEF promotes the apoptosis of H/R human NSCLC cells and inhibites the expression of AQP1 and ENaC proteins,
indicating that PBEF may play potential adjuvant therapeutic role in the treatment of NSCLC.
The Mechanism, Regulatory Effect of Wnt5α/Ca2+ Signaling Pathway on hMSCs Osteogenic Differentiation Under Infection Conditions
Authors: Yilihamu Yilizati , Yansong Liu , Mingliang Xu , Tianyong Cao , Rongjian Shi
Published: May 2020

Background: The paper aimed to reveal the role and possible regulatory mechanisms of Wnt5 gene and its non-canonical Beta-catenin signaling pathway in osteogenic differentiation and bone repairment of hMSCs under infection environment. Material and Methods : CCK-8 method was
employed to detect the effect of SPA on the proliferation of different hMSCs cells. The histological staining of alizarin red was used to observe the differentiation of cells into osteoblasts. The semi-quantitative detection of osteoblast alkaline phosphatase (ALP) was performed. Fluo-2 assay
was employed to measure the intracellular calcium concentration of different hMSCs before and after osteogenic differentiation stimulated by SPA. RT-PCR was applied to detect the specific gene fluorescence of osteoblasts differentiation. Western Blotting was employed to determine the differentiation
of hMSCs into osteoblasts. Results: Different hMSCs were able to proliferate in vitro under the stimulation of 100 ng/mL SPA. CCK-8 kit was used to detect lentivirus-infected hMSCs and non-transduced hMSCs in vitro. The results showed that all the cells gradually proliferate
with time and an increasing rate. The hMSCs treated with different Wnt5 genes were stained with alizarin red after osteogenic differentiation, and the activities of AMSCs ALP increased. The intracellular free calcium concentration increased with the induction time and peaked in the Wnt5 overexpression
group. PCR results showed that ALP, Runx-2, Collagen I, OC, Osterix and BSP genes were all increased in contrast with the non-induction Control group. Conclusion: Under the inflammatory condition of SPA virulence factors, non-canonical Wnt signaling pathway is associated with the classical
Wnt/ β-catenin signaling pathway in the process of osteogenic differentiation of hMSCs in vitro, which has a certain synergistic effect.

Very Large Scale Integrated (VLSI) technology for a widespread use of high performance portable integrated circuit (IC) devices such as MP3, PDA, mobile phones is increasing rapidly. Most of the VLSI applications, such as digital signal processing, image processing and microprocessors,
extensively use arithmetic operations. In this research novel low power full adder architecture has been proposed for various applications which uses the advanced adder and multiplier designs. A full-adder is one of the essential components in digital circuit design; many improvements have
been made to reduce the architecture of a full adder. In this research modified full adder using GDI technique is proposed to achieve low power consumption. By using GDI cell, the transistor count is greatly reduced, thereby reducing the power consumption and propagation delay while maintaining
the low complexity of the logic design. The parameters in terms of Power, Delay, and Surface area are investigated by comparison of the proposed GDI technology with an optimized 90 nm CMOS technology.

Published: May 2020

Combi-Fault collapsing is a very important approach to reduce linked stuck at faults and to cause effective faults in a combinational circuit. It can significantly moderate the problem of test generation and test work. In this paper, MAXFAN (Maximum Fanout Branch) partitioning is converted
into gate level circuit with site of reconvergence into Fanout-Free Regions and implication of faulty values in the cone is passed over to identify checkpoint faults, equivalence and dominance faults. This method is to compute the tests for SSF (single stuck at faults) and consequently achieves
low fault collapse ratio. Experimental result shows that max fanout partitioning reduces the number of checkpoints and also reduces the maximum number of faults with low collapse ratio.

Published: May 2020

In this paper, we bring about the idea of water level monitoring and controlling with IOT and Mobile applications. The vast amount of water wasted in the current scenario, mostly due to overflowing tanks is not acceptable. Existing water tanks control systems can monitor and control
the water level in tank, which leads to reduction in amount of wastage of ample water but the type of sensors which are used in such a system does not specify exact changes in water level leading to unstable control parameters. Other technologies had some drawbacks based on speed of detection
and approximation of sensor data. The need of improvement of these short-comings and providing an accurate and ethinic solution has been the main aim of this project. The project has been further improvised by using electronic water level sensors which uses potentiometric techniques to measure
water level in water tanks, along with ultrasonic sensors for better metrics and control. Further up, this project can be implemented on large scale to control and detect rising water levels in dams and reservoirs to avoid flash floods and excess pressure in dams. The proposed system will
help to identify the smallest changes in water level in case of rainfall measurement as well.

Published: May 2020

This paper develops a new image denoising framework based on the Dual Tree Complex Wavelet Transform and an edge based patch grouping. The proposed patch grouping mechanism considers the photometric features along with gradient features to cluster the image patches into different groups
with similar properties. Furthermore, the K-means algorithm was accomplished for patch grouping instead of Euclidean distance metric. An adaptive thresholding mechanism is also developed here to remove the noise with less information loss at edge features. Extensive simulation is carried out
through MATLAB software over different grayscale images at different noise levels and noise types and the performance is measured with the performance metrics such as PSNR and SSIM for varying noise levels. The obtained simulation revealed the outstanding performance of proposed approach both
in the preservation of edge features and also in the quality improvisation by efficient noise removal.

Levels and predictors of anxiety, depression and health anxiety during COVID-19 pandemic in Turkish society: The importance of gender
Authors: Özdin Selçuk , Bayrak Özdin Şükriye
Published: May 2020

Background:

The COVID-19 pandemic is having negative effects on societies’ mental health. Both the pandemic and the measures taken to combat it can affect individuals’ mental health.

Aims:

The purpose of this study was to evaluate the levels of depression, anxiety and health anxiety in Turkish society during the COVID-19 pandemic, and to examine the factors affecting these.

Method:

The study was performed using an online questionnaire. Participants were asked to complete a sociodemographic data form, the Hospital Anxiety and Depression Scale (HADS) and the Health Anxiety Inventory (HAI). The effects on depression, anxiety and health anxiety levels of factors such as age, sex, marital status, living with an individual aged above 60, the presence of a new Coronavirus+ patient among friends or relatives, previous and current psychiatric illness and presence of accompanying chronic disease were then investigated.

Results:

In terms of HADS cut-off points, 23.6% ( n = 81) of the population scored above the depression cut-off point, and 45.1% ( n = 155) scored above the cut-off point for anxiety. In regression analysis, female gender, living in urban areas and previous psychiatric illness history were found as risk factors for anxiety; living in urban areas was found as risk factor for depression; and female gender, accompanying chronic disease and previous psychiatric history were found as risk factors for health anxiety.

Conclusion:

The results of this cross-sectional study suggest that the groups most psychologically affected by the COVID-19 pandemic are women, individuals with previous psychiatric illness, individuals living in urban areas and those with an accompanying chronic disease. Priority might therefore be attached to these in future psychiatric planning.

Published: May 2020

Objectives:

To explore the diagnostic value and pathological correlation of narrow band imaging (NBI) classification in laryngeal lesions.

Methods:

A total of 112 patients (123 lesions) with laryngeal lesions from July 2018 to May 2019 were selected in this study. All patients were examined by NBI and white light imaging endoscopy. The NBI endoscopy was applied to classify the observed lesion sites according to intraepithelial papillary capillary loop pattern. The gold standard of diagnosis was pathological results. To evaluate the consistency of NBI classification and pathological results.

Results:

The sensitivity, specificity, positive predictive value, and negative predictive value of the diagnosis for benign, precancerous, and malignant lesions under the NBI endoscopy were 90.91%, 81.19%, 74.07%, 85.42%; 41.67%, 92.93%, 58.82%, 86.79%; and 93.51%, 65.22%, 91.14%, 68.18%, respectively. There was a high consistency between NBI classification and pathological results (κ = 0.679, P < .001).

Conclusions:

The NBI classification can improve the accuracy of the diagnosis of laryngeal lesions. It is important for early diagnosis and treatment of vocal cord leukoplakia and laryngeal cancer.
Canadian Society of Thoracic Radiology/Canadian Association of Radiologists Consensus Statement Regarding Chest Imaging in Suspected and Confirmed COVID-19
Authors: Dennie Carole , Hague Cameron , Lim Robert S. , Manos Daria , Memauri Brett F. , Nguyen Elsie T. , Taylor Jana
Published: May 2020

On March 11, 2020, the World Health Organization declared infection related to a novel coronavirus (SARS-CoV-2) a pandemic. The role and impact of imaging predates this declaration and continues to change rapidly. This article is a consensus statement provided by the Canadian Society of Thoracic Radiology and the Canadian Association of Radiologists outlining the role of imaging in COVID-19 patients. The objectives are to answer key questions related to COVID-19 imaging of the chest and provide guidance for radiologists who are interpreting such studies during this pandemic. The role of chest radiography (CXR), computed tomography (CT), and lung ultrasound is discussed. This document attempts to answer key questions for the imager when dealing with this crisis, such as “When is CXR appropriate in patients with suspected or confirmed COVID-19 infection?” or “How should a radiologist deal with incidental findings of COVID-19 on CT of the chest done for other indications?” This article also provides recommended reporting structure for CXR and CT, breaking diagnostic possibilities for both CXR and CT into 3 categories: typical, nonspecific, and negative based on imaging findings with representative images provided. Proposed reporting language is also outlined based on this structure. As our understanding of this pandemic evolves, our appreciation for how imaging fits into the workup of patients during this unprecedented time evolves as well. Although this consensus statement was written using the most recent literature, it is important to maintain an open mind as new information continues to surface.
L’analyse du discours des journaux de presse français à propos de la crise de migrants en France, en 2016
Authors: Špadijer Sonja
Published: May 2020

UNESCO (2018), souligne le rôle que jouent les médias dans la création des représentations négatives et stéréotypées des migrants. Ce présent article analysera la façon dont la presse écrite française a rapporté les nouvelles concernant la crise de migrants dans le camp de Calais, entre août et décembre 2016. Notre intention est de vérifier de quelle manière les journaux appartenant à des orientations éditoriales variées voire opposées font passer les informations concernant ce groupe de migrants. Comme les journaux se serviraient de différents moyens linguistiques pour faire passer leurs messages tels le choix de vocabulaire, de thèmes, de structures de phrases, la méthodologie de notre recherche s’appuiera sur l’analyse critique du discours ainsi que sur les outils de la lexicométrie. C’est grâce à l’enchevêtrement des procédures de travail que nous avons réussi à révéler différents éléments évaluatifs dont les journaux se serviraient afin de communiquer leurs idéologies.
Between narrative and practice: Storytelling as a way of knowing how to be in nature
Authors: Maslen Sarah
Published: May 2020

This article examines the storytelling practices of adventurers as a means to shape embodied experience. While scholars mostly treat narrative and practice separately, examining them simultaneously reveals their mutual constitution and tensions. Stories often precede the embodied learning that occurs through going into the outdoors. However, they only make sense at the point of the encounter and the experience can change the lesson. Key aspects of the embodied experience often remain unspoken, both due to time delays between the experience and its telling and the inadequacies of language. This analysis is based on interviews, participant observation, and “go-alongs” with adventurers based in Australia and New Zealand.

Published: May 2020

Venous (cavernous) malformations are commonly seen in the upper limb. Almost all venous malformations are congenital. They may be sporadic, familial, or syndromic. Late-onset, multiple venous malformations confined to the upper limb are rare. Lesions present after puberty. All previously reported cases were located subcutaneously and were small in size. The condition is non-hereditary and non-syndromic. We present a unique series of eight patients with this rare condition. Unique features included the presence of large malformations (up to 20 cm in diameter) and the presence of subfascial lesions causing nerve compression. Surgical excision was curative. Mutational analysis in one patient identified a novel somatic MAP3K3 gene mutation (c.1723T > C, p.Tyr 575 His) in the affected veins. The encoded MAP3K3 protein is known to accelerate the RAS pathway of cellular proliferation.

Mass of piled lumber estimated through vibration test
Authors: Kubojima Yoshitaka , Sonoda Satomi , Kato Hideo
Published: May 2020

The aim of this study is to propose a method for measuring the mass of wood lumber in piles through a vibration test. Air-dried sitka spruce (Picea sitchensis Carr.) pieces with 1500–1600 mm length (L), 105 mm width (R), and 105 mm thickness (T) were used as specimens. We created a model of wood lumber inside a pile. A load 10 times that of the specimen was applied to the specimen, and vibration was initiated in the direction of the specimen’s length. The vibration test was conducted for the specimen with, and without a small steel plate. The specimen mass was estimated without weighing using the method based on the difference of the resonance frequency when a concentrated mass is added to and subtracted from wood. The specimen mass was thus estimated accurately through this vibration method. It is possible that the mass of the water removed from the wood lumber by drying can be estimated with this vibration method.

Background

Headache sufferers in need of professional health care often do not utilize the care available, and factors influencing headache-specific physician consultation are not yet understood. Objectives of this study are (1) to assess self-reported headache-specific physician consultations and (2) to identify headache-related and sociodemographic predictors.

Methods

Data of a random sample of the general population in Germany aged ≥14 years were analyzed (N = 2461). A multivariate binary logistic regression was conducted to identify a parsimonious model to predict physician consultation.

Results

50.7% of the participants with headache reported at least one headache-specific physician consultation during lifetime. Of these, 53.6% had seen one, 26.1% two, and 20.3% more than two physicians because of their headaches. The odds of physician consultation increased with the number of headache days per month (HDM) [(reference HDM < 1) HDM 1–3 (OR = 2.29), HDM 4–14 (OR = 2.41), and HDM ≥15 (OR = 4.83)] and increasing Headache Impact Test score (HIT-6) [(reference “no or little impact”) moderate impact (OR = 1.74), substantial impact (OR = 3.01), and severe impact (OR = 5.08)]. Middle-aged participants were more likely to have consulted than younger and older ones [(reference 14–34 years) 35–54 years (OR = 1.90), 55–74 years (OR = 1.96), ≥75 years (OR = 1.02)]. The odds of physician consultation among self-employed subjects were lower than among employed manual workers (OR = 0.48). The living environment (rural versus urban) did not have an influence on the consultation frequency.

Conclusion

The results indicate that apart from burden-related factors (headache frequency; headache impact), health care utilization patterns are also influenced by patients’ occupational status and age. Further research is needed to analyze whether the lower consultation rate means that the self-employed have a higher risk of chronification or that they have more effective self-management strategies regarding headache.
