The blood was modeled as a two phase mixture (an aqueous carbon dioxide solution with carbon dioxide gas) by Drift flux model and the Young-Laplace equation. The distributions of mixture velocities determined from the considered model permitted the calculation of the radial velocity distributions with different values of mean mixture pressure and the calculation of the mean carbon dioxide pressure knowing the mean mixture pressure. The radial velocity distributions are used to deduce a calculation method of the mean mixture pressure through the radial velocity difference between two positions which is measured by ultrasound.

For this, we have studied the influence of the temperature and the different concentrations of the antifreeze on the corrosion of these three metals, this will last for two months by the polarization method and weight loss. In the end, we investigated the samples with the optic microscope to know their surface state. The aim of this work is the protection of contraptions. The use of antifreeze in ordinary water has a high efficiency against steel corrosion, as demonstrated by electrochemical tests (potential monitoring as a function of time and tracing polarization curves). The inhibition rate is greater than 99% for different volume concentrations, ranging from 40% to 60%. The speeds are in turn low in the order of 10-4 mm/year. On the other hand, the addition of antifreeze to ordinary water increases the corrosion potential of steel by more than 400 mV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion%20and%20prevention" title="corrosion and prevention">corrosion and prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum" title=" aluminum"> aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20inhibitor" title=" corrosion inhibitor"> corrosion inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-cooling" title=" anti-cooling"> anti-cooling</a> </p> <a href="https://publications.waset.org/abstracts/185967/the-behavior-of-steel-copper-and-aluminum-vis-a-vis-the-corrosion-in-an-aqueous-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185967.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">50</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">75</span> Modelling and Simulation of Milk Fouling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harche%20Rima">Harche Rima</a>, <a href="https://publications.waset.org/abstracts/search?q=Laoufi%20Nadia%20Aicha"> Laoufi Nadia Aicha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on the study and modeling of the fouling phenomenon in a vertical pipe. In the first step, milk is one of the fluids obeying the phenomenon of fouling because of the denaturation of these proteins, especially lactoglobulin, which is the active element of milk, and to facilitate its use, we chose to study milk as a fouling fluid. In another step, we consider the test section of our installation as a tubular-type heat exchanger that works against the current and in a closed circuit. A simple mathematical model of Kern & Seaton, based on the kinetics of the fouling resistance, was used to evaluate the influence of the operating parameters (fluid flow velocity and exchange wall temperature) on the fouling resistance. The influence of the variation of the fouling resistance with the operating conditions on the efficiency of the heat exchanger and the importance of the dirty state exchange coefficient as an exchange quality control parameter were discussed and examined. On the other hand, an electronic scanning microscope analysis was performed on the milk deposit in order to obtain its actual image and composition, which allowed us to calculate the thickness of this deposit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fouling" title="fouling">fouling</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a>, <a href="https://publications.waset.org/abstracts/search?q=tubular%20heat%20exchanger" title=" tubular heat exchanger"> tubular heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=fouling%20resistance" title=" fouling resistance"> fouling resistance</a> </p> <a href="https://publications.waset.org/abstracts/185965/modelling-and-simulation-of-milk-fouling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185965.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">52</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">74</span> Total Arterial Coronary Revascularization with Aorto-Bifemoral Bipopliteal Bypass: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuruddin%20Mohammod%20Zahangir">Nuruddin Mohammod Zahangir</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Tanvir%20Ahmady"> Syed Tanvir Ahmady</a>, <a href="https://publications.waset.org/abstracts/search?q=Firoz%20Ahmed"> Firoz Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mainul%20Kabir"> Mainul Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamjid%20Mohammad%20Najmus%20Sakib%20Khan"> Tamjid Mohammad Najmus Sakib Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazmul%20Hossain"> Nazmul Hossain</a>, <a href="https://publications.waset.org/abstracts/search?q=Niaz%20Ahmed"> Niaz Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhava%20Janardhan%20Naik"> Madhava Janardhan Naik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The management of combined Coronary Artery Disease and Peripheral Vascular Disease is a challenge and brings with it numerous clinical dilemmas.The 56 year old gentleman presented to our department with significant triple vessel disease with occluded lower end of aorta just before bifurcation and bilateral superficial femoral arteries. Operation was done on 11.03.14. The The Left Internal Mammary Artery (LIMA) and the Right Internal Mammary Artery (RIMA) were harvested in skeletonized manner. The free RIMA was then anastomosed with LIMA to make LIMA-RIMA Y. Cardio Pulmonary Bypass was then established and coronary artery bypass grafts performed. LIMA was anastomosed to the Left Anterior Descending artery. RIMA was anastomosed to Posterior Descending Artery, 1st and 2nd Obtuse Marginal arteries in a sequential manner. Abdomen was opened by midline incision. The infrarenal aorta exposed and was found to be severely diseased. A Vascular Clamp was applied infrarenally, aortotomy done and limited endarterectomy performed. An end-to-side anastomosis was done with upper end of PTFE synthetic Y-graft (14/7 mm) to the infarenal Aorta and the Clamp released. Good flow noted in both limbs of the graft. Patient was then slowly weaned off from Cardio Pulmonary Bypass without difficulty. The distal two limbs of the Y graft were passed to the groin through retroperitoneal tunnels and anastomosed end-to-side with the common femoral arteries. Saphenous vein was interposed between common femoral and popliteal arteries bilaterally through subfascial tunnels in both thigh. On 12th postoperative day he was discharged from hospital in good general condition. Follow up after 3 months of operation the patient is doing good and free of chest pain and claudication pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20arterial" title="total arterial">total arterial</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20revascularization" title=" coronary revascularization"> coronary revascularization</a>, <a href="https://publications.waset.org/abstracts/search?q=aorto-bifemoral%20bypass" title=" aorto-bifemoral bypass"> aorto-bifemoral bypass</a>, <a href="https://publications.waset.org/abstracts/search?q=bifemoro-bipopliteal%20bypass" title=" bifemoro-bipopliteal bypass"> bifemoro-bipopliteal bypass</a> </p> <a href="https://publications.waset.org/abstracts/12890/total-arterial-coronary-revascularization-with-aorto-bifemoral-bipopliteal-bypass-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12890.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">472</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">73</span> The Issues of Irrigation and Drainage in Kebbi State and Their Effective Solution for a Sustainable Agriculture in Kebbi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mumtaz%20Ahmed%20Sohag">Mumtaz Ahmed Sohag</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishaq%20Ahmed%20Sohag"> Ishaq Ahmed Sohag</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kebbi State, located in the Nort-West of Nigeria, is rich in water resources as the major rivers viz. Niger and Rima irrigate a vast majority of land. Besides, there is significant amount of groundwater, which farmers use for agriculture purpose. The groundwater is also a major source of agricultural and domestic water as wells are installed in almost all parts of the region. Although Kebbi State is rich in water, however, there are some pertinent issues which are hampering its agricultural productivity. The low lands (locally called Fadama), has spread out to a vast area. It is inundated every year during the rainy season which lasts from June to September every year. The farmers grow rice during the rainy season when water is standing. They cannot do further agricultural activity for almost two months due to high standing water. This has resulted in widespread waterlogging problem. Besides, the impact of climate change is resulting in rapid variation in river/stream flows. The information about water bodies regarding the availability of water for agricultural and other uses and the behavior of rivers at different flows is seldom available. Furthermore, sediment load (suspended and bedload) is not measured due to which land erosion cannot be countered effectively. This study, carried out in seven different irrigation regions of Kebbi state, found that diversion structures need to be constructed at some strategic locations for the supply of surface water to the farmers. The water table needs to be lowered through an effective drainage system. The monitoring of water bodies is crucial for sound data to help efficient regulation and management of water. Construction of embankments is necessary to control frequent floods in the rivers of Niger and Rima. Furthermore, farmers need capacity and awareness for participatory irrigation management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20bodies" title="water bodies">water bodies</a>, <a href="https://publications.waset.org/abstracts/search?q=floods" title=" floods"> floods</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=waterlogging" title=" waterlogging"> waterlogging</a> </p> <a href="https://publications.waset.org/abstracts/80448/the-issues-of-irrigation-and-drainage-in-kebbi-state-and-their-effective-solution-for-a-sustainable-agriculture-in-kebbi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80448.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">238</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">72</span> A Methodology for Sustainable Interoperability within Collaborative Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Koulou">Aicha Koulou</a>, <a href="https://publications.waset.org/abstracts/search?q=Norelislam%20El%20Hami"> Norelislam El Hami</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Hmina"> Nabil Hmina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims at presenting basic concepts and principles in order to develop a methodology to set up sustainable interoperability within collaborative networks.

Within a self-similar model for the hydrodynamic multi-fluid equations, we investigated the expansion of dense plasma. The weakly relativistic electrons are produced by ultra-intense laser pulses, while ions are supposed to be in a non-relativistic regime. It is shown that dense plasma expansion is found to be governed mainly by quantum contributions in the fluid equations that originate from the degenerate pressure in addition to the nonlinear contributions from exchange and correlation potentials. The quantum degeneracy parameter proﬁle provides clues to set the limit between under-dense and dense relativistic plasma expansions at a given density and temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasma%20expansion" title="plasma expansion">plasma expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20degeneracy" title=" quantum degeneracy"> quantum degeneracy</a>, <a href="https://publications.waset.org/abstracts/search?q=weakly%20relativistic" title=" weakly relativistic"> weakly relativistic</a>, <a href="https://publications.waset.org/abstracts/search?q=under-dense%20%20plasma" title=" under-dense plasma"> under-dense plasma</a> </p> <a href="https://publications.waset.org/abstracts/167933/contribution-of-exchange-correlation-effects-on-weakly-relativistic-plasma-expansion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167933.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">87</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">64</span> Experimental Investigation of Hull Form for Electric Driven Ferry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vasilij%20Djackov">Vasilij Djackov</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Zapnickas"> Tomas Zapnickas</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgenii%20Iamshchikov"> Evgenii Iamshchikov</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukas%20Norkevicius"> Lukas Norkevicius</a>, <a href="https://publications.waset.org/abstracts/search?q=Rima%20Mickeviciene"> Rima Mickeviciene</a>, <a href="https://publications.waset.org/abstracts/search?q=Larisa%20Vasiljeva"> Larisa Vasiljeva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the resistance and pitching values of the test of an electric ferry are presented.

Firstly, it consists of categorizing the data by assigning it to a category and possibly a sub-category, and secondly, of establishing relations between columns and possibly discovering the semantics of the manipulated data source.

So, a treatment fungicide is one of means of diseases control. In this context, we studied two varieties of wheat; Waha for soft wheat and Hidhab for hard wheat, at the level of the Technical Institute of crops (ITGC) in the wilaya of Setif under semi-arid conditions. This study consists of a successive application of three fungicides (Tilt, Artea, and Armistarxtra) according to three treatments (T1, T2, and T3) in addition to the witness (T0) at different stages of plant development (respectively, Montaison, earing and after flowering) whose purpose is to test and determine the effectiveness of these products used sequentially. The study showed good efficacy when we use the sum of these pesticides The comparison between these different treatments indicates that the T3 treatment reduced yield losses significantly; which is evident in the main yield components such as fertility, grain yield and weight of 1000 grains. The various components of yield and final yield are all parameters to be taken into account in such a study. In general, the fungal treatment is an effective way of improving profitability. In general, the fungal treatment is an effective way of improving profitability and positioning interventions in time is one of the requirements for an appreciable efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hard%20wheat" title="hard wheat">hard wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20wheat" title=" soft wheat"> soft wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=diseases" title=" diseases"> diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=fungicide%20treatment" title=" fungicide treatment"> fungicide treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=fertility" title=" fertility"> fertility</a>, <a href="https://publications.waset.org/abstracts/search?q=1000-grain%20weight" title=" 1000-grain weight"> 1000-grain weight</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-arid%20zone" title=" semi-arid zone"> semi-arid zone</a> </p> <a href="https://publications.waset.org/abstracts/14541/comparative-study-of-the-effect-of-three-fungicides-tilt-and-artea-amistarxtra-about-growing-wheat-hard-and-soft-and-their-impact-on-grain-yield-and-its-components-in-the-semi-arid-zone-of-setif" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14541.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">406</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">58</span> Enhancement of Indexing Model for Heterogeneous Multimedia Documents: User Profile Based Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Aggoune">Aicha Aggoune</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkrim%20Bouramoul"> Abdelkrim Bouramoul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Khiereddine%20Kholladi"> Mohamed Khiereddine Kholladi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent research shows that user profile as important element can improve heterogeneous information retrieval with its content.

The proposed gradient mechanism, presented in this paper, is based on the principle of the Di Zenzo’s approach using quaternion representation. This edge detector is compared to a marginal approach based on multiscale product of wavelet transform and another vector approach based on quaternion convolution and vector gradient approach. The experimental results indicate that the proposed color gradient operator outperforms marginal approach, however, it is less efficient then the second vector approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gradient" title="gradient">gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20detection" title=" edge detection"> edge detection</a>, <a href="https://publications.waset.org/abstracts/search?q=color%20image" title=" color image"> color image</a>, <a href="https://publications.waset.org/abstracts/search?q=quaternion" title=" quaternion"> quaternion</a> </p> <a href="https://publications.waset.org/abstracts/141138/review-on-quaternion-gradient-operator-with-marginal-and-vector-approaches-for-colour-edge-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141138.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">234</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">53</span> Process Driven Architecture For The ‘Lessons Learnt’ Knowledge Sharing Framework: The Case Of A ‘Lessons Learnt’ Framework For KOC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rima%20Al-Awadhi">Rima Al-Awadhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Jaleel%20Tharayil"> Abdul Jaleel Tharayil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On a regular basis, KOC engages into various types of Projects. However, due to very nature and complexity involved, each project experience generates a lot of ‘learnings’ that need to be factored into while drafting a new contract and thus avoid repeating the same mistakes. But, many a time these learnings are localized and remain as tacit leading to scope re-work, larger cycle time, schedule overrun, adjustment orders and claims. Also, these experiences are not readily available to new employees leading to steep learning curve and longer time to competency. This is to share our experience in designing and implementing a process driven architecture for the ‘lessons learnt’ knowledge sharing framework in KOC.

The aim of this study is to evaluate the effect of SDF on reducing Candida albicans adhesion on dentin. Materials and Methods: Bovine dentin disks (6×6 mm) were cut by Isomet and polished using grit silicon carbide papers down to 2000 in order to obtain flat dentin surfaces. Samples were divided into two groups. The first group (SDF group) was treated with 38% SDF for 3 min, while the other group (control group) did not undergo SDF treatment. All samples were exposed to C. albicans suspension, washed after 6 hours incubation at 30 °C before to be tested using XTT (2,3-Bis-(2-Methoxy-4-Nitro-5-Sulfophenyl)-2H-Tetrazolium-5-Carboxanilide) and real time PCR approaches. Statistical analyses of the results were performed at the significance level α = 0.05. Results: SDF inhibited C. albicans adhesion onto dentin. A significant difference was found between the SDF and control groups in both XTT and real time PCR tests. Conclusion: Using SDF to arrest the caries, could inhibit the Candida growth on dentin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silver%20diamine%20fluoride" title="silver diamine fluoride">silver diamine fluoride</a>, <a href="https://publications.waset.org/abstracts/search?q=dentin" title=" dentin"> dentin</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20PCR" title=" real time PCR"> real time PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=XTT" title=" XTT"> XTT</a> </p> <a href="https://publications.waset.org/abstracts/103950/effect-of-silver-diamine-fluoride-on-reducing-fungal-adhesion-on-dentin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103950.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">162</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">50</span> The Effect of the Calcination Temperature and SiO2 Addition on the Physical Properties’ of Sol Gel TiO2 Thin Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nour%20El%20Houda%20Arabi">Nour El Houda Arabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Iratni"> Aicha Iratni</a>, <a href="https://publications.waset.org/abstracts/search?q=Talaighil%20Razika"> Talaighil Razika</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Capoen"> Bruno Capoen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Bouazaoui"> Mohamed Bouazaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we report the effect of the calcination temperature and SiO2 addition on structural, optical and hydrophilicity of TiO2 films deposited by deep-coating sol-gel process. XRD investigation of the structural TiO2 films with increasing the temperature calcination, reveals that rutile phase will appear for the high temperature (>1000°C). However, the addition of SiO2 relate the densification of TiO2 films. Ellipsometric and UV-visible measure show that the refractive index grow with increasing temperature, against the film thickness decreases. On the other hand, the addition of SiO2 decreases the refractive index and increases the TiO2 film thickness. Finally, the hydrophilicity is assisted by contact angle measurement. It is found that addition of 50% of SiO2 to TiO2 is most effective for reducing the contact angle of water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20properties" title="physical properties">physical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=sol" title=" sol"> sol</a>, <a href="https://publications.waset.org/abstracts/search?q=gel" title=" gel"> gel</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2%2FSiO2%20composite%20films" title=" TiO2/SiO2 composite films"> TiO2/SiO2 composite films</a> </p> <a href="https://publications.waset.org/abstracts/24780/the-effect-of-the-calcination-temperature-and-sio2-addition-on-the-physical-properties-of-sol-gel-tio2-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24780.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">493</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">49</span> Anti-Inflammatory Activity of Lavandula antineae Maire from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soumeya%20Krimat">Soumeya Krimat</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Dob"> Tahar Dob</a>, <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Kesouri"> Aicha Kesouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Nouasri"> Ahmed Nouasri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafidha%20Metidji"> Hafidha Metidji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lavandula antineae Maire is an endemic medicinal plant of Algeria which is traditionally used for the treatment of chills, bruises, oedema and rheumatism.
