fuzzy second-order sliding mode control (FSOSMC) for wind energy conversion system based on a doubly-fed induction generator (DFIG). The proposed control strategy combines a fuzzy logic and a second-order sliding mode for the DFIG control. This strategy presents attractive features such as chattering-free, compared to the conventional first and second order sliding mode techniques. The use of this method provides very satisfactory performance for the DFIG control. The overall strategy has been validated on a 1.5-MW wind turbine driven a DFIG using the Matlab/Simulink. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly%20fed%20induction%20generator" title="doubly fed induction generator">doubly fed induction generator</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20second-order%20sliding%20mode%20controller" title=" fuzzy second-order sliding mode controller"> fuzzy second-order sliding mode controller</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title=" wind energy"> wind energy</a> </p> <a href="https://publications.waset.org/abstracts/29410/a-novel-fuzzy-second-order-sliding-mode-control-of-a-doubly-fed-induction-generator-for-wind-energy-conversion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29410.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">549</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">45</span> Modeling of Leaks Effects on Transient Dispersed Bubbly Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Kessal">Mohand Kessal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Boucetta"> Rachid Boucetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Tikobaini"> Mourad Tikobaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Zamoum"> Mohammed Zamoum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leakage problem of two-component fluids flow is modeled for a transient one-dimensional homogeneous bubbly flow and developed by taking into account the effect of a leak located at the middle point of the pipeline.

The common objective of many of these methods is to supply classification criteria. The purpose of this study is to present a method for assessing the seismic performance of structures, based on Pushover method, we are particularly interested in reinforced concrete frame structures, which represent a significant percentage of damaged structures after a seismic event. The work is based on the characterization of seismic movement of the various earthquake zones in terms of PGA and PGD that is obtained by means of SIMQK_GR and PRISM software and the correlation between the points of performance and the scalar characterizing the earthquakes will be developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title="seismic performance">seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover%20method" title=" pushover method"> pushover method</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization%20of%20seismic%20motion" title=" characterization of seismic motion"> characterization of seismic motion</a>, <a href="https://publications.waset.org/abstracts/search?q=harmfulness%20of%20the%20seismic" title=" harmfulness of the seismic"> harmfulness of the seismic</a> </p> <a href="https://publications.waset.org/abstracts/29929/introduction-of-the-harmfulness-of-the-seismic-signal-in-the-assessment-of-the-performance-of-reinforced-concrete-frame-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29929.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">383</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">42</span> Computation of Stress Intensity Factor Using Extended Finite Element Method </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Noureddine">Mahmoudi Noureddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouregba%20Rachid"> Bouregba Rachid </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the stress intensity factors of a slant-cracked plate of AISI 304 stainless steel, have been calculated using extended finite element method and finite element method (FEM) in ABAQUS software, the results were compared with theoretical values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stress%20intensity%20factors" title="stress intensity factors">stress intensity factors</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20finite%20element%20method" title=" extended finite element method"> extended finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel" title=" stainless steel"> stainless steel</a>, <a href="https://publications.waset.org/abstracts/search?q=abaqus" title=" abaqus"> abaqus</a> </p> <a href="https://publications.waset.org/abstracts/22230/computation-of-stress-intensity-factor-using-extended-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22230.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">618</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">41</span> Behavior of Laminated Plates under Mechanical Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Noureddine">Mahmoudi Noureddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study the use of two variable refined plate theories of laminated composite plates to static response of laminated plates.

These fibers were used for their low cost, their availability and their renewable character. The fibers of the palm (palm tree) were used as reinforcement in polypropylene (PP). The date palm fibers have some potential because of their ecological and economic interest. Both unmodified and compatibilized fibers are used. Compatibilization was carried out with the use of maleic anhydride copolymers. The morphology and mechanical properties were characterized by electron microscopy scanning (SEM) and tensile tests. The influence of fiber content on mechanical properties of composite PP / date palm has been evaluated and demonstrated, that the maximum stress and elongation decreases with increasing fiber volume rate. On the other hand, an increase of the tensile modulus has been noticed, but after the fibers improvement, the maximum stress increases significantly up to 25% weight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plant%20fiber" title="plant fiber">plant fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=palm" title=" palm"> palm</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=compatibilizer" title=" compatibilizer"> compatibilizer</a> </p> <a href="https://publications.waset.org/abstracts/28197/composite-base-natural-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28197.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">459</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">36</span> Effect of Solution Heat Treatment on Intergranular Corrosion Resistance of Welded Stainless Steel AISI 321</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Mahmoudi">Amir Mahmoudi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this investigation, AISI321 steel after welding by Shilded Metal Arc Welding (SMAW) was solution heat treated in various temperatures and times, and then was sensitizied.

The practice difficulties are complex due to the complexity of deformation mechanism, to the complex mechanism of the material tearing and to the marked interactions between the tribological parameters. In this work, we present an experimental technique to study the elastomers abrasive wear. The interaction 'elastomer/indenter' implicate dependant ant temporary of different tribological parameters. Consequently, the phenomenon that governs this interaction is not easy to explain. An optimal elastomers compounding and an adequate utilization conditions of these materials that define its resistance at the abrasion is discussed. The results are confronted to theoretical models: the weight loss variation in function of blade angle or in function of cycle number is in agreement with rupture models and with the mechanism of fissures propagation during the material tearing in abrasive wear of filler elastomers. The weight loss in function of the sliding velocity shows the existence of a critical velocity that corresponds to the maximal wear. The adding of silica or black carbon influences in a different manner on wear abrasive behavior of filler elastomers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abrasion%20wear" title="abrasion wear">abrasion wear</a>, <a href="https://publications.waset.org/abstracts/search?q=filler%20elastomer" title=" filler elastomer"> filler elastomer</a>, <a href="https://publications.waset.org/abstracts/search?q=tribology" title=" tribology"> tribology</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperelastic" title=" hyperelastic"> hyperelastic</a> </p> <a href="https://publications.waset.org/abstracts/25969/filler-elastomers-abrasion-at-steady-state-optimal-use-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25969.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">322</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">34</span> Application of the Piloting Law Based on Adaptive Differentiators via Second Order Sliding Mode for a Fixed Wing Aircraft </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zaouche%20Mohammed">Zaouche Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amini%20Mohammed"> Amini Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Foughali%20Khaled"> Foughali Khaled</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamissi%20Aicha"> Hamissi Aicha</a>, <a href="https://publications.waset.org/abstracts/search?q=Aktouf%20Mohand%20Arezki"> Aktouf Mohand Arezki</a>, <a href="https://publications.waset.org/abstracts/search?q=Boureghda%20Ilyes"> Boureghda Ilyes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a piloting law based on the adaptive differentiators via high order sliding mode controller, by using an aircraft in virtual simulated environment.

Firstly, we developed a model of matrix converter, controlled by the Venturini modulation technique. In order to control the power exchanged between the stator of the DFIG and the grid, a control law is synthesized using a high order sliding mode controller. The use of this method provides very satisfactory performance for the DFIG control.

They bring many functional advantages: lightness, mechanical resistance and chemical, etc. In the present study we examine the effect of a circular central notch and a precrack on the tensile fracture of two woven composite materials. The tensile tests were applied to a standardized specimen, notched and a precracked (orientation of the crack 0掳, 45掳, and 90掳). These tensile tests were elaborated according to an experimental planning design of the type 23.31 requiring 24 experiments with three repetitions. By the analysis of regression, we obtained a mathematical model describing the maximum load according to the influential parameters (hole diameter, precrack length, angle of a precrack orientation). The specimens precracked at 90掳 have a better behavior than those having a precrack at 45掳 and still better than those having of the precracks oriented at 0掳. In addition the maximum load is inversely proportional to the notch size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20matrix" title="polymer matrix">polymer matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=glasses" title=" glasses"> glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=precracks" title=" precracks"> precracks</a> </p> <a href="https://publications.waset.org/abstracts/14713/application-of-the-experimental-planning-design-to-the-notched-precracked-tensile-fracture-of-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14713.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">344</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">30</span> Preparation and Physical Assessment of Portland Cement Base Composites Containing Nano Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Mahmoudi">Amir Mahmoudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research the effects of adding silica and alumina nanoparticles on flow ability and compressive strength of cementitious composites based on Portland cement were investigated.

This wellfield is located in the northeast of the city of Adrar, it covers an area of 132.56 km2 with 21 Drinking Water Supply wells (DWS), pumping a total flow of approximately 13 Hm3/year. The choice of this wellfield is based on the favorable hydrodynamic characteristics and their location in relation to the agglomeration. The vulnerability to pollution of this slick is very high because the slick is free and suffers from the absence of a protective layer. In recent years, several factors have been introduced around the field that can affect the quality of this precious resource, including the presence of a strong centre for domestic waste and agricultural and industrial activities. Thus, its sustainability requires the implementation of protection perimeters. The objective of this study is to set up three protection perimeters: immediate, close and remote. The application of the Wyssling method makes it possible to calculate the transfer time (t) of a drop of groundwater located at any point in the aquifer up to the abstraction and thus to define isochrones which in turn delimit each type of perimeter, 40 days for the nearer and 100 days for the farther away. Special restrictions are imposed for all activities depending on the distance of the catchment. The application of this method to the Adrar city catchment field showed that the close and remote protection perimeters successively occupy areas of 51.14 km2 and 92.9 km2. Perimeters are delimited by geolocated markers, 40 and 46 markers successively. These results show that the areas defined as "near protection perimeter" are free from activities likely to present a risk to the quality of the water used. On the other hand, on the areas defined as "remote protection perimeter," there is some agricultural and industrial activities that may present an imminent risk. A rigorous control of these activities and the restriction of the type of products applied in industrial and agricultural is imperative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continental%20intercalaire" title="continental intercalaire">continental intercalaire</a>, <a href="https://publications.waset.org/abstracts/search?q=drinking%20water%20supply" title=" drinking water supply"> drinking water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=perimeter%20of%20protection" title=" perimeter of protection"> perimeter of protection</a>, <a href="https://publications.waset.org/abstracts/search?q=wyssling%20method" title=" wyssling method"> wyssling method</a> </p> <a href="https://publications.waset.org/abstracts/149631/delimitation-of-the-perimeters-of-pr-otection-of-the-wellfield-in-the-city-of-adrar-sahara-of-algeria-through-the-used-wysslings-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149631.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">96</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">28</span> Wear Damage of Glass Fiber Reinforced Polyimide Composites with the Addition of Graphite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Noureddine">Mahmoudi Noureddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The glass fiber (GF) reinforced polyimide (PL) composites filled with graphite powders were fabricated by means of hot press molding technique. The friction and wear properties of the resulting composites sliding against GCr15 steel were investigated on a model ring-on-block test rig at dry sliding condition. The wear mechanisms were also discussed, based on scanning electron microscopic examination of the worn surface of the PL composites and the transfer film formed on the counterpart. With the increasing normal loads, the friction coefficient of the composites increased under the dry sliding, owing to inconsistent influences of shear strength and real contact areas. Experimental results revealed that the incorporation of graphite significantly improve the wear resistance of the glass fibers reinforced polyimide composites. For best combination of friction coefficient and wear rate, the optimal volume content of graphite in the composites appears to be 45 %. It was also found that the tribological properties of the glass fiber reinforced PL composites filled with graphite powders were closely related with the sliding condition such as sliding rate and applied load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composites" title="composites">composites</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber" title=" fiber"> fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/41664/wear-damage-of-glass-fiber-reinforced-polyimide-composites-with-the-addition-of-graphite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41664.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">356</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">27</span> Evaluation of the Diagnostic Potential of IL-2 as Biomarker for the Discrimination of Active and Latent Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shima%20Mahmoudi">Shima Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Setareh%20Mamishi"> Setareh Mamishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Pourakbari"> Babak Pourakbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Marjani"> Majid Marjani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last years, the potential role of distinct T-cell subsets as biomarkers of active tuberculosis TB and/or latent tuberculosis infection (LTBI) has been studied. The aim of this study was to investigate the potential role of interleukin-2 (IL-2) in whole blood stimulated with M. tuberculosis-specific antigens in the QuantiFERON-TB Gold In Tube (QFT-G-IT) for the discrimination of active and latent tuberculosis. After 72-h of stimulation by antigens from the QFT-G-IT assay, IL-2 secretion was quantitated in supernatants by using ELISA (Mabtech AB, Sweden). Observing the level of IL-2 released after 72-h of incubation, we found that the level of IL-2 were significantly higher in LTBI group than in patients with active TB infection or control group (P value=0.019, Kruskal鈥揥allis test). The discrimination performance (assessed by the area under ROC curve) between LTBI and patients with active TB was 0.816 (95%CI: 0.72-0.97). Maximum discrimination was reached at a cut-off of 13.9 pg/mL for IL-2 following stimulation with 82% sensitivity and 86% specificity. In conclusion, although cytokine analysis has greatly contributed to the understanding of TB pathogenesis, data on cytokine profiles that might distinguish progression from latency of TB infection are scarce and even controversial. Our data indicate that the concomitant evaluation of IFN- 纬 and IL-2 could be instrumental in discriminating of active and latent TB infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interleukin-2" title="interleukin-2">interleukin-2</a>, <a href="https://publications.waset.org/abstracts/search?q=discrimination" title=" discrimination"> discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20TB" title=" active TB"> active TB</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20TB" title=" latent TB"> latent TB</a> </p> <a href="https://publications.waset.org/abstracts/21198/evaluation-of-the-diagnostic-potential-of-il-2-as-biomarker-for-the-discrimination-of-active-and-latent-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21198.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">408</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">26</span> Comparison of Salt-Water Intrusion into Eastern and Western Coastal Aquifers of Urmia Lake thru Over-Exploration of Groundwater Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saman%20Javadi">Saman Javadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hassan%20Mahmoudi"> Mohammad Hassan Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Jafari"> Fatemeh Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aminreza%20Neshat"> Aminreza Neshat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urmia Lake鈥檚 water level has been dropped during the past decade. Although the most common reason in studies was declared climate change, but observation of adjacent lake (like Van in Turkey) is not the same as the common reason. Most of studies were focused on climate and land use change, but groundwater resource as one of the most important element is negligible. Due to population and agriculture activities growth, exploration of groundwater resource has been increased. In as much as continued decline of water levels can lead to saltwater intrusion, reduce stream discharge near outcrop regions and threaten groundwater quality, aquifers of this region were affected by saltwater intrusion of Urmia Lake. In this research comparison of saltwater intrusion into eastern and western coastal aquifer was studied. In conclusion eastern aquifers are in a critical situation; vice versa the western ones are in a better situation. Thus applying management of groundwater operation would be necessary for eastern aquifers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20aquifer" title="coastal aquifer">coastal aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20over-exploration" title=" groundwater over-exploration"> groundwater over-exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=saltwater%20intrusion" title=" saltwater intrusion"> saltwater intrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Urmia%20Lake" title=" Urmia Lake"> Urmia Lake</a> </p> <a href="https://publications.waset.org/abstracts/20314/comparison-of-salt-water-intrusion-into-eastern-and-western-coastal-aquifers-of-urmia-lake-thru-over-exploration-of-groundwater-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20314.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">539</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">25</span> Oral Antibiotics in Trans-Rectal Prostate Biopsy and Its Efficacy to Reduce Infectious Complications: Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Yaghi">Mohand Yaghi</a>, <a href="https://publications.waset.org/abstracts/search?q=O.%20Kehinde"> O. Kehinde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: For the diagnosis of prostate cancer Trans-rectal prostate biopsy (TRPB) is used commonly, the procedure is associated with infective complications. There is evidence that antibiotics (ABx) decrease infective events after TRPB, but different regimens are used. Aim: To systematically review different regimens of prophylactic oral antibiotics in TRPB. Design: Medline, Embase, Clinical trials site, and Cochrane library were searched, experts were consulted about relevant studies. Randomized clinical trials (RCT) conducted in the last twenty years, which investigated different oral antibiotic regimens in TRPB, and compared their efficacy to reduce infectious complications were analyzed. Measurements: Primary outcomes were bacteriuria, urinary tract infection (UTI), fever, bacteremia, sepsis. Secondary outcomes were hospitalization rate, and the prevalence of ABx-resistant bacteria. Results: Nine trials were eligible with 3012 patients. Antibiotics prevented bacteriuria (3.5% vs. 9.88%), UTI (4.46% vs. 9.75%), and hospitalization (0.21% vs. 2.13%) significantly in comparison with placebo or no treatment. No significant difference was found in all outcomes of the review between the single dose regimen and the 3 days. The single dose regimen was as effective as the multiple dose except in Bacteriuria (6.75% vs. 3.25%), and the prevalence of ABx-resistant bacteria (1.57% vs. 0.27%). Quinolones reduced only UTI significantly in comparison with other antibiotics. Lastly, Ciprofloxacin is the best Quinolone to prevent UTI, and hospitalization. Conclusion: it is essential to prescribe prophylactic Antibiotics in TRPB. No conclusive evidence could be claimed about the superiority of the multiple or the 3 days regimens to the single dose regimen. Unexpectedly, ABx-resistant bacteria was identified more often in the single dose cohorts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infection" title="infection">infection</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=sepsis" title=" sepsis"> sepsis</a>, <a href="https://publications.waset.org/abstracts/search?q=TRPB" title=" TRPB"> TRPB</a> </p> <a href="https://publications.waset.org/abstracts/34146/oral-antibiotics-in-trans-rectal-prostate-biopsy-and-its-efficacy-to-reduce-infectious-complications-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34146.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">368</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">24</span> The Effects of Spark Plasma on Infectious Wound Healing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erfan%20Ghasemi">Erfan Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Khani"> Mohammadreza Khani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Mahmoudi"> Hamidreza Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali%20Nilforoushzadeh"> Mohammad Ali Nilforoushzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Shokri"> Babak Shokri</a>, <a href="https://publications.waset.org/abstracts/search?q=Pouria%20Akbartehrani"> Pouria Akbartehrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given the global significance of treating infectious wounds, the goal of this study is to use spark plasma as a new treatment for infectious wounds. To generate spark plasma, a high-voltage (7 kV) and high-frequency (75 kHz) source was used. Infectious wounds in the peritoneum of mice were divided into control and plasma-treated groups at random. The plasma-treated animals received plasma radiation every 4 days for 12 days, for 60 seconds each time. On the 15th day after the first session, the wound in the plasma-treated group had completely healed. The spectra of spark plasma emission and tissue properties were studied. The mechanical resistance of the wound healed in the plasma treatment group was considerably higher than in the control group (p<0.05), according to the findings. Furthermore, histological evidence suggests that wound re-epithelialization is faster in comparison to controls. Angiogenesis and fibrosis (collagen production) were also dramatically boosted in the plasma-treated group, whereas the stage of wound healing inflammation was significantly reduced. Plasma therapy accelerated wound healing by causing considerable wound constriction. The results of this investigation show that spark plasma has an influence on the treatment of infectious wounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infectious%20wounds" title="infectious wounds">infectious wounds</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a>, <a href="https://publications.waset.org/abstracts/search?q=spark%20plasma" title=" spark plasma"> spark plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/140938/the-effects-of-spark-plasma-on-infectious-wound-healing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140938.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">295</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">23</span> Chelating Effect of Black Tea Extract Compared to Citric Acid in the Process of the Oxidation of Sunflower, Canola, Olive, and Tallow Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Naserzadeh">Yousef Naserzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloufar%20Mahmoudi"> Niloufar Mahmoudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oxidation resistance is one of the important parameters in maintaining the quality of olive oil during its storage. Ensuring the stability of the quality of olive oil is one of the important concerns of the producers and consumers. Prooxidants such as iron and copper accelerate the oxidation reaction, and also anti-oxidants and chelating compounds delay it. In this study, chelating effect of tea extract which contains significant amounts of tannic acid is investigated in comparison with citric acid. To do it, 0.1 ppm copper was added to these four kinds of oil, sunflower, olive, canola, and tallow, and then chelating effect of citric acid (0.01%), tannic acid (0.01%) and tea extract (0.1%) were measured by adding to this composition. To this end, the resistance time of the oils against oxidation was measured at 120 掳C and an air flow of 20 liters per hour. And the value of peroxide was measured by oven test in six periods of 24 hours at 105 掳C. The results showed that citric acid, tannic acid and tea extract had chelating property and increased the resistance time of the studied oils. As a result, considering chelating property and increasing resistance of oil, tannic acid showed better effect than tea extract and tea extract had better effect than citric acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tannic%20acid" title="tannic acid">tannic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=chelate" title=" chelate"> chelate</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20oils" title=" edible oils"> edible oils</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20tea%20extract" title=" black tea extract"> black tea extract</a>, <a href="https://publications.waset.org/abstracts/search?q=TBHQ" title=" TBHQ"> TBHQ</a> </p> <a href="https://publications.waset.org/abstracts/90906/chelating-effect-of-black-tea-extract-compared-to-citric-acid-in-the-process-of-the-oxidation-of-sunflower-canola-olive-and-tallow-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90906.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">203</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">22</span> Current and Future Global Distribution of Drosophila suzukii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Naserzadeh">Yousef Naserzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloufar%20Mahmoudi"> Niloufar Mahmoudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a vinegar fly native to South East Asia, has recently invaded Europe, North- and South America and is spreading rapidly. Species distribution modeling has been widely employed to indicate probable areas of invasion and to guide management strategies. Drosophila sp. is native to Asia, but since 2015, it has invaded almost every country in the world, including Africa, Australia, India, and most recently, the Americas. The growth of this species of Drosophila suzukii has been rapidly multiplying and spreading in the last decade. In fact, we examine and model the potential geographical distribution of D. suzukii for both present and future scenarios. Finally, we determine the environmental variables that affect its distribution, as well as assess the risk of encroachment on protected areas. D.suzukii has the potential to expand its occurrence, especially on continents that have already been invaded. The predictive models obtained in this study indicate potential regions that could be at risk of invasion by D. suzukii, including protected areas. These results are important and can assist in the establishment of management plans to avoid the possible harm caused by biological invasions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=Drosophila%20suzukii" title=" Drosophila suzukii"> Drosophila suzukii</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20variables" title=" environmental variables"> environmental variables</a>, <a href="https://publications.waset.org/abstracts/search?q=host%20preference" title=" host preference"> host preference</a>, <a href="https://publications.waset.org/abstracts/search?q=host%20plant" title=" host plant"> host plant</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a> </p> <a href="https://publications.waset.org/abstracts/146306/current-and-future-global-distribution-of-drosophila-suzukii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146306.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">85</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">21</span> The Developments Trend of Islamic Inscriptions in the Building Portals of Dezfoul City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahnoush%20Mahmoudi">Mahnoush Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Chaeedeh"> Ali Chaeedeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the architecture of Iranian traditional houses, the ornamentations available in the inscriptions of houses entrance portal express the identity of architects and personality of houses owners and are rooted in their religious and national beliefs and faiths. The main hypothesis of this research is changing the physique and application of religious contents in compliance with the thoughts and beliefs of people in Dezfoul historical city in the epigraphs of houses entrance portals. The objective of this study is reviewing the development trend of texts, concepts and physique of inscriptions as well as analyzing the factors effective on the quality and diversity of application of inscriptions. The present research is an applied study and descriptive-analytical method has been applied, and the data was collected by library and survey studies. The population of this research includes historical houses, houses damaged in war (Iran & Iraq) and renovated and new tissue and new-built houses of Dezfoul, from Qajar era so far. Random sampling method has been applied in this study and dispersal area includes the city. Data analysis method in this study is qualitative and quantitative. The results of this study indicate that today the inscriptions available in the entrance portal of houses in Dezfoul comparing to inscriptions in Qajar1 and Pahlavi2 era is very simple and has lower aesthetic value. One of the causes for such superficial and contextual gap between inscriptions seems to be the war and renovations during and after destruction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=islamic%20architecture" title=" islamic architecture"> islamic architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=reconstruction" title=" reconstruction"> reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=epigraph" title=" epigraph"> epigraph</a>, <a href="https://publications.waset.org/abstracts/search?q=inscription" title=" inscription"> inscription</a>, <a href="https://publications.waset.org/abstracts/search?q=entrance%20portal" title=" entrance portal"> entrance portal</a>, <a href="https://publications.waset.org/abstracts/search?q=Dezfoul" title=" Dezfoul"> Dezfoul</a> </p> <a href="https://publications.waset.org/abstracts/35396/the-developments-trend-of-islamic-inscriptions-in-the-building-portals-of-dezfoul-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35396.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">245</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">20</span> MLProxy: SLA-Aware Reverse Proxy for Machine Learning Inference Serving on Serverless Computing Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nima%20Mahmoudi">Nima Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamzeh%20Khazaei"> Hamzeh Khazaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Serving machine learning inference workloads on the cloud is still a challenging task at the production level. The optimal configuration of the inference workload to meet SLA requirements while optimizing the infrastructure costs is highly complicated due to the complex interaction between batch configuration, resource configurations, and variable arrival process. Serverless computing has emerged in recent years to automate most infrastructure management tasks. Workload batching has revealed the potential to improve the response time and cost-effectiveness of machine learning serving workloads. However, it has not yet been supported out of the box by serverless computing platforms. Our experiments have shown that for various machine learning workloads, batching can hugely improve the system鈥檚 efficiency by reducing the processing overhead per request. In this work, we present MLProxy, an adaptive reverse proxy to support efficient machine learning serving workloads on serverless computing systems. MLProxy supports adaptive batching to ensure SLA compliance while optimizing serverless costs. We performed rigorous experiments on Knative to demonstrate the effectiveness of MLProxy. We showed that MLProxy could reduce the cost of serverless deployment by up to 92% while reducing SLA violations by up to 99% that can be generalized across state-of-the-art model serving frameworks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serverless%20computing" title="serverless computing">serverless computing</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=inference%20serving" title=" inference serving"> inference serving</a>, <a href="https://publications.waset.org/abstracts/search?q=Knative" title=" Knative"> Knative</a>, <a href="https://publications.waset.org/abstracts/search?q=google%20cloud%20run" title=" google cloud run"> google cloud run</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/148895/mlproxy-sla-aware-reverse-proxy-for-machine-learning-inference-serving-on-serverless-computing-platforms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148895.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">179</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">19</span> A Multi-Objective Programming Model to Supplier Selection and Order Allocation Problem in Stochastic Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rouhallah%20Bagheri">Rouhallah Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Mahmoudi"> Morteza Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Moheb-Alizadeh"> Hadi Moheb-Alizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims at developing a multi-objective model for supplier selection and order allocation problem in stochastic environment, where purchasing cost, percentage of delivered items with delay and percentage of rejected items provided by each supplier are supposed to be stochastic parameters following any arbitrary probability distribution. In this regard, dependent chance programming is used which maximizes probability of the event that total purchasing cost, total delivered items with delay and total rejected items are less than or equal to pre-determined values given by decision maker. The abovementioned stochastic multi-objective programming problem is then transformed into a stochastic single objective programming problem using minimum deviation method. In the next step, the further problem is solved applying a genetic algorithm, which performs a simulation process in order to calculate the stochastic objective function as its fitness function. Finally, the impact of stochastic parameters on the given solution is examined via a sensitivity analysis exploiting coefficient of variation. The results show that whatever stochastic parameters have greater coefficients of variation, the value of the objective function in the stochastic single objective programming problem is deteriorated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supplier%20selection" title="supplier selection">supplier selection</a>, <a href="https://publications.waset.org/abstracts/search?q=order%20allocation" title=" order allocation"> order allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=dependent%20chance%20programming" title=" dependent chance programming"> dependent chance programming</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/32384/a-multi-objective-programming-model-to-supplier-selection-and-order-allocation-problem-in-stochastic-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32384.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">313</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">18</span> Integrating GIS and Analytical Hierarchy Process-Multicriteria Decision Analysis for Identification of Suitable Areas for Artificial Recharge with Reclaimed Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Marwa">Mahmoudi Marwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahim%20Nadhem"> Bahim Nadhem</a>, <a href="https://publications.waset.org/abstracts/search?q=Aydi%20Abdelwaheb"> Aydi Abdelwaheb</a>, <a href="https://publications.waset.org/abstracts/search?q=Issaoui%20Wissal"> Issaoui Wissal</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Najet"> S.

On regional characteristics, bibliography and available data on artificial recharge, 13 constraints and 5 factors were hierarchically structured for the adequacy of an artificial recharge. The factors are subdivided into two main groups: environmental factors and economic factors. The adopted methodology allows a preliminary assessment of a recharge site, the weighted linear combination (WLC) and the analytical hierarchy process (AHP) in a GIS. The standardization of the criteria is carried out by the application of the different membership functions. The form and control points of the latter are defined by the consultation of the experts. The weighting of the selected criteria is allocated according to relative importance using the AHP methodology. The weighted linear combination (WLC) integrates the different criteria and factors to delineate the most suitable areas for artificial recharge site selection by treated wastewater. The results of this study showed three potential candidate sites that appear when environmental factors are more important than economic factors. These sites are ranked in descending order using the ELECTRE III method. Nevertheless, decision making for the selection of an artificial recharge site will depend on the decision makers in force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20recharge%20site" title="artificial recharge site">artificial recharge site</a>, <a href="https://publications.waset.org/abstracts/search?q=treated%20wastewater" title=" treated wastewater"> treated wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title=" analytical hierarchy process"> analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=ELECTRE%20III" title=" ELECTRE III "> ELECTRE III </a> </p> <a href="https://publications.waset.org/abstracts/105235/integrating-gis-and-analytical-hierarchy-process-multicriteria-decision-analysis-for-identification-of-suitable-areas-for-artificial-recharge-with-reclaimed-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105235.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">166</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">17</span> Investigation of Rifampicin and Isoniazid Resistance Mutated Genes in Mycobacterium Tuberculosis Isolated From Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Mohammad%20Amin%20Mousavi%20Sagharchi">Seyyed Mohammad Amin Mousavi Sagharchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Mahmoudi%20Nasab"> Alireza Mahmoudi Nasab</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Bakker"> Tim Bakker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Mycobacterium tuberculosis (MTB) is the most intelligent bacterium that existed in the world to our best knowledge. This bacterium can cause tuberculosis (TB) which is responsible for its spread speed and murder of millions of people around the world. MTB has the practical function to escape from anti-tuberculosis drugs (AT), for this purpose, it handles some mutations in the main genes and creates new patterns for inhibited genes. Method and materials: Researchers have their best tries to safely isolate MTB from the sputum specimens of 35 patients in some hospitals in the Tehran province and detect MTB by culture on L枚wenstein-Jensen (LJ) medium and microscopic examination. DNA was extracted from the established bacterial colony by enzymatic extraction method. It was amplified by the polymerase chain reaction (PCR) method, reverse hybridization, and evaluation for detection of resistance genes; generally, researchers apply GenoType MTBDRplus assay. Results: Investigations of results declare us that 21 of the isolated specimens (about 60%) have mutation in rpoB gene, which resisted to rifampicin (most prevalence), and 8 of them (about 22.8%) have mutation in katG or inhA genes which resisted to isoniazid. Also, 4 of them (about 11.4%) don't have any mutation, and 2 of them (about 5.7%) have mutation in every three genes, which makes them resistant to the two drugs mentioned above. Conclusion: Rifampicin and isoniazid are two essential AT that using in the first line of treatment. Resistance in rpoB, and katG, and inhA genes related to mentioned drugs lead to ineffective treatment. <p class="card-text"><strong>Keywords:</strong> <a
