viscoelastic behaviour formulating gels based plant extractions. The extracts of Zingibar officinale and Cinnamomum cassia were included in the gel at different concentrations of these plants in order to be applied in anti-inflammatory drugs. The yield of ethanolic extraction of Zingibar o. is 3.98% and for Cinnamomum c., essential oil by hydrodistillation is 1.67 %. The ethanolic extract of Zingibar.o, the essential oil of Cinnamomum c. and the mixture showed an anti-DPPH radicals’ activity, presented by EC50 values of 11.32, 13.48 and 14.39 mg/ml respectively. A gel based on different concentrations of these extracts was prepared. Microbiological tests conducted against Staphylococcus aureus and Escherichia colishowed moderate inhibition of Cinnamomum c. gel and less the gel based on Cinnamomum c./ Zingibar o. (20/80). The yeast Candida albicansis resistant to gels. The viscoelastic formulation property was carried out in dynamic and creep and modeled with the Kelvin-Voigt model. The influence of some parameters on the stability of the gel (time, temperature and applied stress) has been studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cinnamomum%20cassia" title="Cinnamomum cassia">Cinnamomum cassia</a>, <a href="https://publications.waset.org/abstracts/search?q=Zingibar%20officinale" title=" Zingibar officinale"> Zingibar officinale</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobien%20activity" title=" antimicrobien activity"> antimicrobien activity</a>, <a href="https://publications.waset.org/abstracts/search?q=gel" title=" gel"> gel</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelastic%20behaviour" title=" viscoelastic behaviour"> viscoelastic behaviour</a> </p> <a href="https://publications.waset.org/abstracts/168525/rheological-characterization-of-gels-based-on-medicinal-plant-extracts-mixture-zingibar-officinale-and-cinnamomum-cassia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168525.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">89</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">7</span> Mecano-Reliability Approach Applied to a Water Storage Tank Placed on Ground</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amar%20Aliche">Amar Aliche</a>, <a href="https://publications.waset.org/abstracts/search?q=Hocine%20Hammoum"> Hocine Hammoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Karima%20Bouzelha"> Karima Bouzelha</a>, <a href="https://publications.waset.org/abstracts/search?q=Arezki%20Ben%20Abderrahmane"> Arezki Ben Abderrahmane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditionally, the dimensioning of storage tanks is conducted with a deterministic approach based on partial coefficients of safety. These coefficients are applied to take into account the uncertainties related to hazards on properties of materials used and applied loads. However, the use of these safety factors in the design process does not assure an optimal and reliable solution and can sometimes lead to a lack of robustness of the structure. The reliability theory based on a probabilistic formulation of constructions safety can respond in an adapted manner. It allows constructing a modelling in which uncertain data are represented by random variables, and therefore allows a better appreciation of safety margins with confidence indicators. The work presented in this paper consists of a mecano-reliability analysis of a concrete storage tank placed on ground. The classical method of Monte Carlo simulation is used to evaluate the failure probability of concrete tank by considering the seismic acceleration as random variable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20approach" title="reliability approach">reliability approach</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20tanks" title=" storage tanks"> storage tanks</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo%20simulation" title=" monte carlo simulation"> monte carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20acceleration" title=" seismic acceleration"> seismic acceleration</a> </p> <a href="https://publications.waset.org/abstracts/46607/mecano-reliability-approach-applied-to-a-water-storage-tank-placed-on-ground" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46607.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">308</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">6</span> New Bioactive Compounds from Two Chrysanthemum Saharian Species (Asteraceae) Growing in Algeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahia%20Kabouche">Zahia Kabouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouissem%20Gherboudj"> Ouissem Gherboudj</a>, <a href="https://publications.waset.org/abstracts/search?q=Naima%20Boutaghane"> Naima Boutaghane</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Kabouche"> Ahmed Kabouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurence%20Voutquenne-Nazabadioko"> Laurence Voutquenne-Nazabadioko </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chrysanthemum herbs (Asteraceae) are extensively used as food additives and in folk medicine.

We report the isolation and identification of flavonoids and new and known terpenoids from the endemic species, C. macrocarpum and C. deserticolum “guertoufa”, used in Algerian Sahara as tea drinks and in “couscous” and soups “Chorba”. Structures of the isolated compounds were established by 1-D and 2-D homo and hetero-nuclear NMR (1H, 13C, COSY, HSQC, HMBC, and NOESY), mass spectrometry, UV and comparison with literature data. C. deserticolum extracts were tested by four methods to identify the antioxidant activity namely, ABTS•+, DPPH• scavenging, CUPRAC and ferrous-ions chelating activity methods.

However, this concentration of fibre is not easy to obtain when formulating feeds, without reduction of nutritional value. Three stage olive cake, the residual material after oil extraction by centrifugation, including pulp and stones, can be used as a fibre source in rabbit diet. The incorporation of olive cake can allow a better balance between different fibre fractions and reduce health disorder. However, for practical use of any raw material, it is necessary to know its chemical and nutritive value. The aim of this study was to assess the nutritive value of three-stage olive cake (TSOC) for growing rabbits. Thus, 36 rabbits weaned at 35 days (702.8 ± 28.5) were divided into three groups of 12 receiving one of the following diets: control with 0% of TSOC, TSOC10 (10% of TSOC) and TSOC20 (20% TSOC). The rabbits were individually housed in digestibility cages and received ad libitum one of the three diets, fresh and clean water was provided ad libitum. After an adaptation period of 7d, feces were collected for 4d. Collected feces were frozen and stored for further analysis. The chemical composition of TSOC shows that it is a rich fiber raw material since it contains (%DM): 6% of CP; 7.4% of EE; 78.7% of NDF; 55.4% of ADF and 24.3% of ADL. The inclusion of TSOC at 20% of basal diet reduced the digestibility coefficient of organic matter, crude protein and NDF from 67.8 to 55.3%, 80.4 to 75.3% and from 31.5 to 18.4% (p < 0.001) respectively. The digestible energy and digestible protein content of the three-stage olive cake estimated by regression was 2.94 ± 0.52MJ DE/kg DM and 22.4 ± 6 g DP/kg DM respectively. In conclusion, based on the results of the present experiment, the three-stage olive cake can be used as a fibre source for rabbit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digestibility" title="digestibility">digestibility</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritive%20value" title=" nutritive value"> nutritive value</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20cake" title=" olive cake"> olive cake</a>, <a href="https://publications.waset.org/abstracts/search?q=rabbit" title=" rabbit"> rabbit</a> </p> <a href="https://publications.waset.org/abstracts/106579/nutritive-value-of-three-stage-olive-cake-olea-europaea-l-for-growing-rabbit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106579.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">156</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">4</span> Dairy Products on the Algerian Market: Proportion of Imitation and Degree of Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bentayeb-Ait%20Lounis%20Sa%C3%AFda">Bentayeb-Ait Lounis Saïda</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheref%20Zahia"> Cheref Zahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cherifi%20Thizi"> Cherifi Thizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ri%20Kahina%20Bahmed"> Ri Kahina Bahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Kahina%20Hallali%20Yasmine%20Abdellaoui"> Kahina Hallali Yasmine Abdellaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenza%20Adli"> Kenza Adli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Algeria is the leading consumer of dairy products in North Africa. This is a fact. However, the nutritional quality of the latter remains unknown. The aim of this study is to characterise the dairy products available on the Algerian market in order to assess whether they constitute a healthy and safe choice. To do this, it collected data on the labelling of 390 dairy products, including cheese, yoghurt, UHT milk and milk drinks, infant formula and dairy creams. We assessed their degree of processing according to the NOVA classification, as well as the proportion of imitation products. The study was carried out between March 2020 and August 2023. The results show that 88% are ultra-processed; 84% for 'cheese', 92% for dairy creams, 92% for 'yoghurt', 100% for infant formula, 92% for margarines and 36% for UHT milk/dairy drinks. As for imitation/analogue dairy products, the study revealed the following proportions: 100% for infant formula, 78% for butter/margarine, 18% for UHT milk/milk-based drinks, 54% for cheese, 2% for camembert and 75% for dairy cream. The harmful effects of consuming ultra-processed products on long-term health are increasingly documented in dozens of publications. The findings of this study sound the alarm about the health risks to which Algerian consumers are exposed. Various scientific, economic and industrial bodies need to be involved in order to safeguard consumer health in both the short and long term. Food awareness and education campaigns should be organised. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dairy" title="dairy">dairy</a>, <a href="https://publications.waset.org/abstracts/search?q=UPF" title=" UPF"> UPF</a>, <a href="https://publications.waset.org/abstracts/search?q=NOVA" title=" NOVA"> NOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=yoghurt" title=" yoghurt"> yoghurt</a>, <a href="https://publications.waset.org/abstracts/search?q=cheese" title=" cheese"> cheese</a> </p> <a href="https://publications.waset.org/abstracts/187439/dairy-products-on-the-algerian-market-proportion-of-imitation-and-degree-of-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187439.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">35</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> Antioxidant Activity and Hepatoprotective Potential of Genista quadriflora Munby against Paracetamol-Induced Liver Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nacera%20Baali">Nacera Baali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahia%20Belloum"> Zahia Belloum</a>, <a href="https://publications.waset.org/abstracts/search?q=Souad%20Ameddah"> Souad Ameddah</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadila%20Benayache"> Fadila Benayache</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Benayache"> Samir Benayache</a>, <a href="https://publications.waset.org/abstracts/search?q=Chantal%20Wrutniak-Cabello"> Chantal Wrutniak-Cabello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Allurement of herbs as health beneficial foods and as a source material for the development of new drugs, has led to greater furtherance in the study of herbal medicines during recent years. In the present study, in vitro antioxidant, free radical scavenging capacity, and hepatoprotective activity of butanolic extract from Genista quadriflora Munby (G.quadriflora) were evaluated using established in vitro models such as DPPH radical and hydrogen peroxide radical scavenging activities and antilipidperoxidation ability. Interestingly, the extract showed considerable in vitro antioxidant and free radical scavenging activities in a dose-dependent manner when compared to the standard antioxidant which verified the presence of antioxidant compound in extract tested. The hepatoprotective potential of G.quadriflora extract was also evaluated in male Wistar rats against paracetamol (APAP) induced liver damage. Therapy of G.quadriflora showed the liver protective effect on biochemical and histopathological alterations. Moreover, histological studies also supported the biochemical finding, that is, the maximum improvement in the histoarchitecture of the liver. Results revealed that G.quadriflora extract could protect the liver against APAP-induced oxidative damage by possibly increasing the antioxidant protection mechanism in rats. These findings are of great importance in view of the availability of the plant and its observed possible diverse applications in medicine and nutrition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genista%20quadriflora%20munby" title="genista quadriflora munby">genista quadriflora munby</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=paracetamol" title=" paracetamol"> paracetamol</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/31214/antioxidant-activity-and-hepatoprotective-potential-of-genista-quadriflora-munby-against-paracetamol-induced-liver-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31214.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">473</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> Nondestructive Acoustic Microcharacterisation of Gamma Irradiation Effects on Sodium Oxide Borate Glass X2Na2O-X2B2O3 by Acoustic Signature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Al-Suraihy">Ibrahim Al-Suraihy</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellaziz%20Doghmane"> Abdellaziz Doghmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahia%20Hadjoub"> Zahia Hadjoub </a> </p> <p class="card-text"><strong>Abstract:</strong></p> We discuss in this work the elastic properties by using acoustic microscopes to measure Rayleigh and longitudinal wave velocities in a no radiated and radiated sodium borate glasses X2Na2O-X2B2O3 with 0 ≤ x ≤ 27 (mol %) at microscopic resolution. The acoustic material signatures were first measured, from which the characteristic surface velocities were determined.Longitudinal and shear ultrasonic velocities were measured in a different composition of sodium borate glass samples before and after irradiation with γ-rays. Results showed that the effect due to increasing sodium oxide content on the ultrasonic velocity appeared more clearly than due to γ-radiation. It was found that as Na2O composition increases, longitudinal velocities vary from 3832 to 5636 m/s in irradiated sample and it vary from 4010 to 5836 m/s in high radiated sample by 10 dose whereas shear velocities vary from 2223 to 3269 m/s in irradiated sample and it vary from 2326 m/s in low radiation to 3385 m/s in high radiated sample by 10 dose. The effect of increasing sodium oxide content on ultrasonic velocity was very clear. The increase of velocity was attributed to the gradual increase in the rigidity of glass and hence strengthening of network due to gradual change of boron atoms from the three-fold to the four-fold coordination of oxygen atoms. The ultrasonic velocities data of glass samples have been used to ﬁnd the elastic modulus. It was found that ultrasonic velocity, elastic modulus and microhardness increase with increasing barium oxide content and increasing γ-radiation dose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties%20X2Na2O-X2B2O3" title="mechanical properties X2Na2O-X2B2O3">mechanical properties X2Na2O-X2B2O3</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustic%20signature" title=" acoustic signature"> acoustic signature</a>, <a href="https://publications.waset.org/abstracts/search?q=SAW%20velocities" title=" SAW velocities"> SAW velocities</a>, <a href="https://publications.waset.org/abstracts/search?q=additives" title=" additives"> additives</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma-radiation%20dose" title=" gamma-radiation dose"> gamma-radiation dose</a> </p> <a href="https://publications.waset.org/abstracts/22062/nondestructive-acoustic-microcharacterisation-of-gamma-irradiation-effects-on-sodium-oxide-borate-glass-x2na2o-x2b2o3-by-acoustic-signature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22062.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">1</span> Pathogenic Candida Biofilms Producers Involved in Healthcare Associated Infections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ouassila%20Bekkal%20Brikci%20Benhabib">Ouassila Bekkal Brikci Benhabib</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahia%20Boucherit%20Otmani"> Zahia Boucherit Otmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Kebir%20Boucherit"> Kebir Boucherit</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Seghir"> A.

These therapeutic tools, from their insertion in the body, represent gateways including fungal germs prone. The latter can generate the growth of biofilms, which can be the cause of fungal infection. Faced with this problem, we conducted a study at the University Hospital of Tlemcen in the neurosurgery unit and aims to isolate and identify Candida yeasts from intravenous catheters. Then test their ability to form biofilms. Materials and methods: 256 patient hospitalized in surgery of the hospital in west Algeria were submitted to this study. All samples were taken from peripheral venous catheters implanted for 72 hours or more days. A total of 31 isolates of Candida species were isolated. MIC and SMIC are determined at 80% inhibition by the test XTT tetrazolium measured at 490 nm. The final concentrations of antifungal agent being between 0.03 and 16 mg / ml for amphotericin B and from 0.015 to 8 mg / mL caspofungin. Results: 31 Candida species isolates from catheters including 14 Candida albicans and 17 Candida non albicans . 21 strains of all the isolates were able to form biofilms. In their form of Planktonic cells, all isolates are 100% susceptible to antifungal agents tested. However, in their state of biofilms, more isolates have become tolerant to the tested antifungals. Conclusion: Candida yeasts isolated from intravascular catheters are considered an important virulence factor in the pathogenesis of infections. Their involvement in catheter-related infections can be disastrous for their potential to generate biofilms. They survive high concentrations of antifungal where treatment failure. Pending the development of a therapeutic approach antibiofilm related to catheters, their mastery is going through: -The risk of infection prevention based on the training and awareness of medical staff, -Strict hygiene and maximum asepsis, and -The choice of material limiting microbial colonization. <p class="card-text"><strong>Keywords:</strong> <a
