Experimental study of the hygromechanical behaviour of a historic painting on wooden panel devices and measurement techniques
Venue: Journal of Cultural Heritage
Year: 2020

This article describes the experimental devices and the processes used to study the hygromechanical behaviour of a historic painted wooden panel (La Sainte Trinite couronnant la vierge, 1516, anonymous, Fabre Museum of Montpellier) A climate showcase was designed for in museum use, with two glasses allowing visitors as well as scientists to observe both sides simultaneously. The evaluation of the hygroscopic behaviour was done by measuring relative humidity (RH) temperature and variations of panel weight. Variations of panel shape, strain and curvature were observed by two methods: locally with three pairs of displacement transducers fixed on the rear face, and over the entire panel surface by a non contact optical technique, stereo mark tracking, used simultaneously on both faces. The correlation between local and whole field measurements was very good. Continuous monitoring (several data per hour over three years) was required to observe the behaviour of the panel during imposed climate variations. The first test, detailed in this paper, was performed before frame removal and panel restoration. It consisted in a stabilization of the panel at 52% RH during 2 months and an increase to 63% RH during 3 months. The small amount of total mass variations, from 31.980 kg to 31.910 kg at 52% RH and 32.088 kg at 63% RH, could not be explained without taking into account the phenomenon of sorption hysteresis. The whole field relief measurement exhibited a concave shape with a maximum amplitude of 16 mm. It showed that shape deformation, ie out of plane displacement, was convex bending with a maximum deflection of 1.5 mm and a maximum strain of 0.1 Comparable local data had been obtained by the optical and DKs methods. DKs results were ten times more accurate than optical ones. The horizontal strain exhibited a global shrinkage during initial stabilization and a global swelling during RH increase. Heterogeneity of the strain field can be related to the cracks observed on the back face, and to the glued cross beams. Assuming a linear relationship between swelling and moisture content, we expected, for a 0.6% increase of moisture content, a radial strain of 0.10% and a tangential strain of 0.22% These results are higher than the ones measured, which can be explained by the cross bars glued on the boards and the cracks. This comparison will be continued for the next stages (crossbars removal, panel restoration)

Coping Behaviors and Psychological Disturbances in Youth Affected by the COVID 19 Health Crisis
Venue: Frontiers in Psychology
Year: 2021

The COVID 19 pandemic and the quarantine undergone by children in many countries is a stressful situation about which little is known to date. Children and adolescents' behaviors to cope with home confinement may be associated with their emotional welfare. The objectives of this study were: (1) to examine the coping strategies used out by children and adolescents during the COVID 19 health crisis, (2) to analyze the differences in these behaviors in three countries, and (3) to examine the relationship between different coping modalities and adaptation. Participants were 1,480 parents of children aged 3 18 years from three European countries (n Spain 431, n Italy 712, and n Portugal 355) The children's mean age was 9.15 years (SD 4.27) Parents completed an online survey providing information on symptoms and coping behaviors observed in their children. The most frequent coping strategies were accepting what is happening (58.9% collaborating with quarantine social activities (e.g. drawings on the windows, supportive applauses) (35.9% acting as if nothing is happening (35.5% highlighting the advantages of being at home (35.1% and not appearing to be worried about what is happening (30.1% Compared to Italian and Spanish children, Portuguese children used a sense of humor more frequently when their parents talked about the situation. Acting as if nothing was happening, collaborating with social activities, and seeking comfort from others were more likely in Spanish children than in children from the other countries. Compared to Portuguese and Spanish children, Italian children did not seem worried about what was happening. Overall, an emotional oriented coping style was directly correlated with a greater presence of anxious symptoms, as well as to mood, sleep, behavioral, and cognitive alterations. Task oriented and avoidance oriented styles were related to better psychological adaptation (considered a low presence of psychological symptoms) Results also show that unaffected children or children with a lower level of impact were more likely to use strategies based on a positive focus on the situation. This study provides interesting data on the strategies to be promoted by parents to cope with the COVID 19 health crisis in children.

Venue: 2018 International Conference on Computing, Engineering, and Design (ICCED)
Year: 2018

Along with the increasing use of information and communication technology, information security becomes something fundamental. BATAN as one of the government agencies currently wants to increase the security awareness of its employees. As a national nuclear agency, information security awareness is crucial, as it relates to the safety of the society. This study aims to know how the relationship between the three variables of knowledge, attitude and behavior in BATAN. A nuclear agency has a special characteristics of information security because it has a higher standard related to information security than other institutions. By knowing how the interaction of these three variables, is expected to know how to improve employee behavior toward information security. The arrangement of research variables and instruments is done through Focus Group Discussion (FGD) FGD results were then compiled into questionnaires, distributed to 420 Batan employees. From 420 questionnaire, 381 was returned and processed using regression analysis. As a result, it is known that employee knowledge of information security affects employee attitudes to information security, employee attitudes to information security affect employee behavior in reducing security risks, and employee knowledge of information security affects employee behavior in reducing security risks.
Acute and Subacute Ischemic Stroke A Review of Temperature, Blood Pressure and Glycemic Management
Year: 2016

T he treatment of ischemic stroke is often divided between acute interventions (endovascular therapy, intravenous tissue plasminogen activator [IV tPA] and long term secondary prevention (modifying risk factors, antithrombotic therapy, etc. There is great variability between practitioners in the medical management of stroke during hospitalization, in part because of confusing and contradictory results in the literature. Temperature management and therapeutic hypothermia is discussed in this review. In regards to blood pressure targets, while permissive hypertension is often recognized as a beneficial strategy in acute stroke, blood pressure reduction is essential for secondary stroke prevention. We review the literature regarding optimal timing of different blood pressure goals. Finally, the limited literature regarding glycemic control in ischemic stroke patients is discussed.
Filial responses as predisposed and learned preferences: Early attachment in chicks and babies
Venue: Behavioural Brain Research
Year: 2017

HighlightsPredispositions orient newborn babies and chicks towards animate objects.Subcortical/subpallial structures may be sufficient to support social predispositions.Social Behaviour Network areas might be involved in unlearnt social behaviours.Hormones facilitate preferences for predisposed stimuli and social attachment.Social predispositions are impaired in newborns at high genetic risk for autism.  To what extent are filial responses the outcome of spontaneous or acquired preferences? The case of domestic chicks illustrates the connection between predisposed and learned knowledge in early social responses. In the absence of specific experience, chicks prefer to approach objects that are more similar to natural social partners (e.g. they prefer face like configurations, biological motion, self propelled objects and those that move at variable speed) Spontaneous preferences are complemented by filial imprinting, a powerful learning mechanism that enables chicks to quickly learn the features of specific social partners. While neurobiological studies have clarified that the substrates of spontaneous and learned preferences are at least partially distinct in chicks, evidence shows that spontaneous preferences might orient and facilitate imprinting on animate stimuli, such as the mother hen, and that hormones facilitate and strengthen preferences for predisposed stimuli. Preferences towards animate stimuli are observed in human neonates as well. The remarkable consistency between the perceptual cues attended to by newborn babies and naive chicks suggests that the attentional biases observed in babies are unlikely to result from very rapid post natal learning, and confirms that research on precocial species can inform and guide human infant research with regards to both typical and atypical development. This has potentially important biomedical implications, opening new possibilities for the early detection of subjects at risk for autism spectrum disorders. We show how the parallel investigation of predispositions in naive chicks and human infants, both benefiting from contact with social partners since the beginning of life, has greatly improved our understanding of early responses to social stimuli at the behavioural and neurobiological level.

Acanthopanax senticosus polysaccharide regulates the intestinal homeostasis disruption induced by toxic chemicals in Drosophila
Venue: Phytotherapy research PTR
Year: 2019

The intestinal epithelium provides the first line of defense against pathogens and toxic compounds. The ingestion of toxic compounds causes an enhanced epithelial cell death and an excessive proliferation of intestinal stem cells, eventually resulting in the disruption of gut homeostasis. In this study, Drosophila gut inflammation model induced by toxic compounds was exploited to analyze the ameliorative effect of Acanthopanax senticosus polysaccharide on the disruption of gut homeostasis. As a result, it was found that A. senticosus polysaccharide can significantly increase the survival rate of Drosophila adults as well as reduce the excessive proliferation and differentiation of intestinal stem cells through epidermal growth factor receptor, jun N terminal kinase, and Notch signaling pathways under the exposure to toxic compounds dextran sodium sulfate. Moreover, the polysaccharide effectively decreased the epithelial cell death and the accumulation of reactive oxygen species and antimicrobial peptides induced by sodium dodecyl sulfate. In addition, it was found that A. senticosus polysaccharide can extend the lifespan of only female flies but not male flies. In conclusion, A. senticosus polysaccharide has an obvious protective effect on the gut homeostasis of Drosophila melanogaster.

Differential growth and shape formation in plant organs
Venue: Proceedings of the National Academy of Sciences
Year: 2018

Plant leaves and flower petals in nature exhibit a wide variety of complex 3D shapes. Formation of these shapes has largely been studied from genetic and biomolecular viewpoints, overlooking contributions from biophysical factors such as mechanical stress and deformation. By means of computational simulations and quantitative analyses of the growth strains in live plant organs, we develop fundamental mechanistic insights into how nature invokes mechanics in the evolution of four commonly found shapes in plant organs by differential growth. We also demonstrate how these common shapes can be synthetically reproduced in hydrogel using this mechanistic understanding. Our study provides a broad scientific framework for rationalizing plant organ morphogenesis, but also provides pathways for generating bioinspired 3D architectures in soft materials. Morphogenesis is a phenomenon by which a wide variety of functional organs are formed in biological systems. In plants, morphogenesis is primarily driven by differential growth of tissues. Much effort has been devoted to identifying the role of genetic and biomolecular pathways in regulating cell division and cell expansion and in influencing shape formation in plant organs. However, general principles dictating how differential growth controls the formation of complex 3D shapes in plant leaves and flower petals remain largely unknown. Through quantitative measurements on live plant organs and detailed finite element simulations, we show how the morphology of a growing leaf is determined by both the maximum value and the spatial distribution of growth strain. With this understanding, we develop a broad scientific framework for a morphological phase diagram that is capable of rationalizing four configurations commonly found in plant organs: twisting, helical twisting, saddle bending, and edge waving. We demonstrate the robustness of these findings and analyses by recourse to synthetic reproduction of all four configurations using controlled polymerization of a hydrogel. Our study points to potential approaches to innovative geometrical design and actuation in such applications as building architecture, soft robotics and flexible electronics.

Year: 2016

This study was set to examine factors influencing agroforestry upscaling, inter plot natural fertilizer transfer and inter plot income flow in Arsamma watershed. A semi structured questionnaire was used to gather necessary information. Contingency table, chi square, Phi and Cramer's V were used to analyze the data. Access to seedlings was the most important determinant of agroforestry upscaling; and farmers' production orientation, farm size and wealth status ranked, respectively, second, third and fourth. Inter plot natural fertilizer transfer was primarily influenced by participation in agricultural extension. Wealth status and livestock size ranked, respectively, second and third in influencing inter plot natural fertilizer transfer. The study indicated a geographic concept of spatial land use integration for soil fertility management and key factors influencing agroforestry based land use integration. Agroforestry centered diversified small scale agricultural commercialization, tree crop livestock integration, agricultural extension services promotion and multi purpose tree species supply are the way out to upscale agroforestry and agroforestry based spatial land use integration.
Application Layer DDOS Attack Detection Using Hybrid Machine Learning Approach
Year: 2017

Application Layer Distributed Denial of Service (App DDoS) attack has become a major threat to web security. Attack detection is difficult as they mimic genuine user request. This paper proposes a clustering based correlation approach for detecting application layer DDoS attack on HTTP protocol. Proposed approach has two main modules Flow monitoring module and User behavior monitoring module. Flow monitor is responsible to analyze data flow information. User behavior monitor analyses end user behavior. Proposed approach is capable to detect three main attacks on HTTP protocol, i.e. HTTP GET attack, HTTP POST attack and Slow Read attack. It is also possible to detect hybrid type of DDoS attacks which uses a mixture network and application layer DDoS techniques. Comparative analysis of clustering algorithms on generated dataset is also done to demonstrate the effectiveness of detection approach.

Breathalysing and surveying river users in Australia to understand alcohol consumption and attitudes toward drowning risk
Venue: BMC Public Health
Year: 2018

BackgroundLittle is known about people's river usage, a leading drowning location. This study examines alcohol consumption patterns of river users and their attitudes to drowning risk.MethodsA convenience sample of adult (18+ years) river users were surveyed at four river locations. The survey covered eight domains: demographics; river attendance frequency; frequency of engaging in water activities; drinking patterns; alcohol and water safety knowledge; alcohol and water safety attitudes; alcohol consumption; and Blood Alcohol Concentration (BAC) For BAC, participants were asked to record time since their last alcoholic drink and were then breathalysed to record an estimate of their BAC. BAC was examined by BAC reading (negative, positive, =0.050% Hazardous lifetime drinking levels were calculated and their impact on drowning risk evaluated. Univariate and chi square analysis (95% confidence interval) was conducted.ResultsSix hundred eighty four people participated (51.6% female; 49.0% aged 18 34 years) Sixteen percent (15.9% had a positive BAC (Mean BAC 0.068% SD 0.08; Range 0.001 0.334% with 7.2% =0.050% (Mean BAC =0.050% =0.132% SD 0.06) Those significantly more likely to record a BAC =0.050% at the river were: aged 18 34 years, resided in inner regional and low socio economic areas, visited the river in the afternoon, with friends, on days with higher maximum air temperatures, frequent river users (11+ times in the last 30 days) and those who spend longer in the water (301+ minutes) River users who recorded a BAC =0.050% were more likely to self report engaging in risky activities (i.e. diving into water of unknown depth and jumping into the river from height) River users on Australia day (a national public holiday) were significantly more likely to drink heavily (Mean BAC =0.05% 0.175% SD 0.09).ConclusionsDespite males accounting for 85% of alcohol related river drowning deaths, similar numbers of males and females were consuming alcohol at the river. This study has addressed a gap in knowledge by identifying river usage and alcohol consumption patterns among those at increased drowning risk. Implications for prevention include delivering alcohol related river drowning prevention strategies to both males and females; at peak times including during hot weather, afternoons, public holidays and to river users who swim.
