Metabolism of agricultural plants is altered the following infection with pathogens sometimes contributing to resistance. At the same time, pathogens use metabolites for infection and progression. In humans, metabolism is a hallmark of cancer development for example. Quantified metabolomics data combined with other omics or clinical data and analyzed using various unsupervised and supervised methods can lead to better diagnosis and prognosis. It can also provide information about resistance as well as contribute knowledge of compounds significant for disease progression or prevention. In this work, different methods for metabolomics quantification and analysis from Nuclear Magnetic Resonance (NMR) measurements that are used for investigation of disease development in wheat and human cells will be presented. One-dimensional 1H NMR spectra are used extensively for metabolic profiling due to their high reliability, wide range of applicability, speed, trivial sample preparation and low cost. This presentation will describe a new method for metabolite quantification from NMR data that combines alignment of spectra of standards to sample spectra followed by multivariate linear regression optimization of spectra of assigned metabolites to samples’ spectra. Several different alignment methods were tested and multivariate linear regression result has been compared with other quantification methods. Quantified metabolomics data can be analyzed in the variety of ways and we will present different clustering methods used for phenotype determination, network analysis providing knowledge about the relationships between metabolites through metabolic network as well as biomarker selection providing novel markers. These analysis methods have been utilized for the investigation of fusarium head blight resistance in wheat cultivars as well as analysis of the effect of estrogen receptor and carbonic anhydrase activation and inhibition on breast cancer cell metabolism. Metabolic changes in spikelet’s of wheat cultivars FL62R1, Stettler, MuchMore and Sumai3 following fusarium graminearum infection were explored. Extensive 1D 1H and 2D NMR measurements provided information for detailed metabolite assignment and quantification leading to possible metabolic markers discriminating resistance level in wheat subtypes. Quantification data is compared to results obtained using other published methods. Fusarium infection induced metabolic changes in different wheat varieties are discussed in the context of metabolic network and resistance. Quantitative metabolomics has been used for the investigation of the effect of targeted enzyme inhibition in cancer. In this work, the effect of 17 β -estradiol and ferulic acid on metabolism of ER+ breast cancer cells has been compared to their effect on ER- control cells. The effect of the inhibitors of carbonic anhydrase on the observed metabolic changes resulting from ER activation has also been determined. Metabolic profiles were studied using 1D and 2D metabolomic NMR experiments, combined with the identification and quantification of metabolites, and the annotation of the results is provided in the context of biochemical pathways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metabolic%20biomarkers" title="metabolic biomarkers">metabolic biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20network" title=" metabolic network"> metabolic network</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20linear%20regression" title=" multivariate linear regression"> multivariate linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=NMR%20quantification" title=" NMR quantification"> NMR quantification</a>, <a href="https://publications.waset.org/abstracts/search?q=quantified%20metabolomics" title=" quantified metabolomics"> quantified metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20alignment" title=" spectral alignment"> spectral alignment</a> </p> <a href="https://publications.waset.org/abstracts/46114/quantified-metabolomics-for-the-determination-of-phenotypes-and-biomarkers-across-species-in-health-and-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46114.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Secure Transfer of Medical Images Using Hybrid Encryption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boukhatem%20Mohamed%20Belkaid">Boukhatem Mohamed Belkaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Lahdi%20Mourad"> Lahdi Mourad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose a new encryption system for security issues medical images.

These digital videos can be made anytime, anywhere and for different purposes. They can also be shared on the Internet in a short period of time and may sometimes contain recordings of illegal acts. The need to reliably trace the origin becomes evident when these videos are used for forensic purposes. This work proposes an algorithm to identify the brand and model of mobile device which generated the video. Its procedure is as follows: after obtaining the relevant video information, a classification algorithm based on sensor noise and Wavelet Transform performs the aforementioned identification process.

We studied the physicochemical properties and the optical properties of the produced coatings by means of standard characterization techniques of Fourier Transform Infrared Spectroscopy (FTIR) combined with UV-Vis Reflectance Spectrophotometry. The absorption peaks at 423 cm-1 and 610 cm-1 were observed for the rutile TiO2 thin films, by FTIR measurements. The absorption peak at 739 cm-1 due to the vibration of the Ti-O bonds, was also detected. UV-Vis Reflectance Spectrophotometry is employed for measuring the optical band gap from the measurements of the TiO2 films reflectance. The optical band gap was then extracted from the reflectance data for the TiO2 sample. It was estimated to be 3.05 eV which agrees with the band gap of commercial rutile TiO2 sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title="titanium dioxide">titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20properties" title=" physicochemical properties"> physicochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=APCVD" title=" APCVD"> APCVD</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a>, <a href="https://publications.waset.org/abstracts/search?q=band%20gap" title=" band gap"> band gap</a> </p> <a href="https://publications.waset.org/abstracts/27069/physicochemical-and-optical-characterization-of-rutile-tio2-thin-films-grown-by-apcvd-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Study of Mechanical Behavior of Unidirectional Composite Laminates According</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deliou%20Adel">Deliou Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Saadalah%20Younes"> Saadalah Younes</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkaid%20Khmissi"> Belkaid Khmissi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dehbi%20Meriem"> Dehbi Meriem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Composite materials, in the most common sense of the term, are a set of synthetic materials designed and used mainly for structural applications; the mechanical function is dominant. The mechanical behaviors of the composite, as well as the degradation mechanisms leading to its rupture, depend on the nature of the constituents and on the architecture of the fiber preform. The profile is required because it guides the engineer in designing structures with precise properties in relation to the needs. This work is about studying the mechanical behavior of unidirectional composite laminates according to different failure criteria. Varying strength parameter values make it possible to compare the ultimate mechanical characteristics obtained by the criteria of Tsai-Hill, Fisher and maximum stress. The laminate is subjected to uniaxial tensile membrane forces. Estimates of their ultimate strengths and the plotting of the failure envelope constitute the principal axis of this study.

FSM has a high degree of occupational hazards that need to be thoroughly understood in order to shape effective solutions. On-field observations of five FSM operations were conducted in Anekal Taluk of southern Karnataka. All five of the FSM operations were privately owned and snowball method of sampling was employed. Two types of FS operations observed were: mechanical emptying involving direct human contact with faecal sludge and mechanical emptying without direct human contact with faecal sludge. Each operation was manned by 3-4 faecal sludge operators (FSOs). None of the observed FSOs used personal protective equipment. According to the WHO semi-quantitative risk assessment, the very high risk occupational hazards identified were dermal contact with faecal sludge, inhalation of toxic gases, and social stigma. The high risk hazards identified were trips and falls, injuries, ergonomic hazards, substance abuse, and mental health problems. In all five FSM operations, the collected faecal sludge was discharged untreated onto abandoned land. FSM in India is fraught with occupational and environmental hazards which need to be urgently addressed. This includes formalizing the institution of FSM, contextualized behaviour change communication, capacity building of local bodies, awareness programmes among agriculturists and FSOs, and designation of sites for the safe harnessing of faecal sludge as soil nutrient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=faecal%20sludge" title="faecal sludge">faecal sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=faecal%20sludge%20management" title=" faecal sludge management"> faecal sludge management</a>, <a href="https://publications.waset.org/abstracts/search?q=FSM" title=" FSM"> FSM</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20hazards" title=" occupational hazards"> occupational hazards</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation" title=" sanitation"> sanitation</a> </p> <a href="https://publications.waset.org/abstracts/116226/beyond-the-water-seal-on-field-observations-of-occupational-hazards-of-faecal-sludge-management-in-southern-karnataka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116226.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Study of the Composition of Lipids in Different Kinds of Packaged Food Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Taidirt">Zineb Taidirt</a>, <a href="https://publications.waset.org/abstracts/search?q=Fathia%20Sebahi"> Fathia Sebahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Karim%20Guarchani"> Mohamed Karim Guarchani</a>, <a href="https://publications.waset.org/abstracts/search?q=Anissa%20Berkane"> Anissa Berkane</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Smail"> Noureddine Smail</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouahiba%20Hadjoudj"> Ouahiba Hadjoudj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cardiovascular diseases are one of the most important causes of death in Algeria. Several risk factors are responsible for this, including the consumption of foods containing saturated fat and trans fatty acids TFAs. This brief presents the results of a descriptive study of the lipid composition of 251 food products marketed in Algeria. The objective of the study is to describe the nature and composition of lipids and to verify the compliance of saturated and trans fatty acids intakes with the regulations. The study is based on data from the nutrition labelling of marketed food products. The results showed that the lipids in foodstuffs are diverse in nature and of varying amounts, but their nature is not specified on all products. In addition, the required content of saturated fatty acids is mentioned only in 29.48% of the products; 21.62% of them do not comply with the standard. Hydrogenation of fats, which produced Trans fatty acids, is common: 19.92% of products contain hydrogenated fats, and 74.89% may contain them according to the aspect of the lipid (solid fat). However, the trans fatty acid content is only mentioned in 5.18% of the products. The latter is above the limits set by Algerian regulations in 50% of the butter samples studied. The composition of lipids in mono- and polyunsaturated fatty acids essential for the body is insufficient: only 13.94% of the products inform their contents on their labels. It is necessary to adopt mandatory restriction of trans fatty acids, to ban the use of partially-hydrogenated oils, and to require required mandatory labeling of the TFAs and the other fatty acids on packaged foods, and to conduct more studies in order to appreciate the intake of TFAs and saturated fat and appreciate their effects on the Algerian population and to get more informed about the composition of the lipid in packaged foods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20diseases" title="cardiovascular diseases">cardiovascular diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition%20labelling" title=" nutrition labelling"> nutrition labelling</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=trans%20fatty%20acids" title=" trans fatty acids"> trans fatty acids</a> </p> <a href="https://publications.waset.org/abstracts/130716/study-of-the-composition-of-lipids-in-different-kinds-of-packaged-food-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130716.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Linear and Nonlinear Resonance of Flat Bottom Hole in an Aluminum Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biaou%20Jean-Baptiste%20Kouchoro">Biaou Jean-Baptiste Kouchoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Anissa%20Meziane"> Anissa Meziane</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Micheau"> Philippe Micheau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Renier"> Mathieu Renier</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Quaegebeur"> Nicolas Quaegebeur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerous experimental and numerical studies have shown the interest of the local defects resonance (LDR) for the Non-Destructive Testing of metallic and composite plates. Indeed, guided ultrasonic waves such as Lamb waves, which are increasingly used for the inspection of these flat structures, enable the generation of local resonance phenomena by their interaction with a damaged area, allowing the detection of defects. When subjected to a large amplitude motion, a nonlinear behavior can predominate in the damaged area. This work presents a 2D Finite Element Model of the local resonance of a 12 mm long and 5 mm deep Flat Bottom Hole (FBH) in a 6 mm thick aluminum plate under the excitation induced by an incident A0 Lamb mode. The analysis of the transient response of the FBH enables the precise determination of its resonance frequencies and the associate modal deformations. Then, a linear parametric study varying the geometrical properties of the FBH highlights the sensitivity of the resonance frequency with respect to the plate thickness. It is demonstrated that the resonance effect disappears when the ratio of thicknesses between the FBH and the plate is below 0.1. Finally, the nonlinear behavior of the FBH is considered and studied introducing geometrical (taken into account the nonlinear component of the strain tensor) nonlinearities that occur at large vibration amplitudes. Experimental analysis allows observation of the resonance effects and nonlinear response of the FBH. The differences between these experimental results and the numerical results will be commented on. The results of this study are promising and allow to consider more realistic defects such as delamination in composite materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=guided%20waves" title="guided waves">guided waves</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20testing" title=" non-destructive testing"> non-destructive testing</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20field%20testing" title=" dynamic field testing"> dynamic field testing</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20ultrasound%2Fvibration" title=" non-linear ultrasound/vibration"> non-linear ultrasound/vibration</a> </p> <a href="https://publications.waset.org/abstracts/146110/linear-and-nonlinear-resonance-of-flat-bottom-hole-in-an-aluminum-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146110.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Iron Supplementation for Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-Analysis of Randomized-Controlled Trials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Cameron">Matthew Cameron</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Yang"> Stephen Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Latifa%20Al%20Kharusi"> Latifa Al Kharusi</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Gosselin"> Adam Gosselin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anissa%20Chirico"> Anissa Chirico</a>, <a href="https://publications.waset.org/abstracts/search?q=Pouya%20Gholipour%20Baradari"> Pouya Gholipour Baradari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Iron supplementation has been evaluated in several randomized controlled trials (RCTs) for the potential to increase baseline hemoglobin and decrease the incidence of red blood cell (RBC) transfusion during cardiac surgery. This study's main objective was to evaluate the evidence for iron administration in cardiac surgery patients for its effect on the incidence of perioperative RBC transfusion. Methods: This systematic review protocol was registered with PROSPERO (CRD42020161927) on Dec. 19th, 2019, and was prepared as per the PRISMA guidelines. MEDLINE, EMBASE, CENTRAL, Web of Science databases, and Google Scholar were searched for RCTs evaluating perioperative iron administration in adult patients undergoing cardiac surgery. Each abstract was independently reviewed by two reviewers using predefined eligibility criteria. The primary outcome was perioperative RBC transfusion, with secondary outcomes of the number of RBC units transfused, change in ferritin level, reticulocyte count, hemoglobin, and adverse events, after iron administration. The risk of bias was assessed with the Cochrane Collaboration Risk of Bias Tool, and the primary and secondary outcomes were analyzed with a random-effects model. Results: Out of 1556 citations reviewed, five studies (n = 554 patients) met the inclusion criteria. The use of iron demonstrated no difference in transfusion incidence (RR 0.86; 95% CI 0.65 to 1.13). There was a low heterogeneity between studies (I²=0%). The trial sequential analysis suggested an optimal information size of 1132 participants, which the accrued information size did not reach. Conclusion: The current literature does not support the routine use of iron supplementation before cardiac surgery; however, insufficient data is available to draw a definite conclusion. A critical knowledge gap has been identified, and more robust RCTs are required on this topic. <p class="card-text"><strong>Keywords:</strong> <a
