Hussain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The conversion of CO₂ into versatile, useful compounds such as fuels and other chemicals remains a challenging frontier in research, demanding the innovation of increasingly effective catalysts. In the present work, a catalyst-incorporating zirconium (Zr) modification within CuO–ZnO–Al₂O₃ (CZA) was synthesized via a co-precipitation method to convert CO₂ into methanol. Furthermore, bio-HZSM-5 was used to promote methanol dehydration to produce dimethyl ether (DME). We prepared the porous hierarchy bio-HZSM-5 with remarkable pore connectivity by utilizing an economical loofah sponge and rice husks as biotemplates. The synthesized catalysts were characterized using Field Emission Scanning Electron Microscopy (FE-SEM), X–ray diffraction (XRD), N₂ adsorption (BET), temperature-programmed desorption (NH₃-TPD) and thermogravimetric analysis (TGA). The Zr addition improved the performance of the CZZA catalyst as a structural promoter, leading to increased DME selectivity and total carbon conversion by enhancing active sites, surface area, and the synergistic interfaces between CuO and ZnO. The presence of silicon in the biomass, notably from the loofah sponge (0.016 wt %) and rice husks (8.3 wt %), also performed a pivotal role in the preparation of bio-HZSM-5. Furthermore, contrasted to the CZZA/com-ZSM-5 catalyst, the integration of CZZA with bio-HZSM-5-L bifunctional catalyst achieved the highest DME yield (12.1 %), DME selectivity (58.6%), CO₂ conversion (22.5%) at 280 °C and 30 bar. The payback time for 5 and 10-tons per day (5 and10-TPD) DME formation using the catalytic process of CO₂ from petrochemical refinery plant waste gas emissions was 2.98 and 2.44 years, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cost%20assessment" title="Cost assessment">Cost assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimethyl%20ether" title=" Dimethyl ether"> Dimethyl ether</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost%20bio-HZSM-5" title=" low-cost bio-HZSM-5"> low-cost bio-HZSM-5</a>, <a href="https://publications.waset.org/abstracts/search?q=CZZA%20catalyst" title=" CZZA catalyst"> CZZA catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20hydrogenation" title=" CO₂ hydrogenation"> CO₂ hydrogenation</a> </p> <a href="https://publications.waset.org/abstracts/194172/synergistic-effect-of-zr-modified-cu-zno-al2o3-and-bio-templated-hzsm-5-catalysts-in-co2-hydrogenation-to-methanol-and-dme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194172.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">10</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">143</span> Effect of Integrated Nutrient Management Practice on Cultivation Scented Rice Varieties- a Better Approach for Resource Conservation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amit%20Kumar%20Patel">Amit Kumar Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20C.%20Bhambri"> M.

Effective therapeutic strategies are urgently needed to combat this disease, particularly in regions with high prevalence. This study focuses on developing and characterizing fluorescent organometallic frameworks as distinct drug delivery carriers with potential applications in both the treatment and biological imaging of liver cancer. This work introduces two distinct organometallic frameworks: the cake-shaped GQD@NH₂-MIL-125 and the cross-shaped M8U6/FM8U6. The GQD@NH₂-MIL-125 framework is particularly noteworthy for its high fluorescence, making it an effective tool for biological imaging. X-ray diffraction (XRD) analysis revealed specific diffraction peaks at 6.81ᵒ (011), 9.76ᵒ (002), and 11.69ᵒ (121), with an additional significant peak at 26ᵒ (2θ), corresponding to the carbon material. Morphological analysis using Field Emission Scanning Electron Microscopy (FE-SEM), and Transmission Electron Microscopy (TEM) demonstrated that the framework has a front particle size of 680 nm and a side particle size of 55±5 nm. High-resolution TEM (HR-TEM) images confirmed the successful attachment of graphene quantum dots (GQDs) onto the NH2-MIL-125 framework. Fourier-Transform Infrared (FT-IR) spectroscopy identified crucial functional groups within the GQD@NH₂-MIL-125 structure, including O-Ti-O metal bonds within the 500 to 700 cm⁻¹ range, and N-H and C-N bonds at 1,646 cm⁻¹ and 1,164 cm⁻¹, respectively. BET isotherm analysis further revealed a specific surface area of 338.1 m²/g and an average pore size of 46.86 nm. This framework also demonstrated UV-active properties, as identified by UV-visible light spectra, and its photoluminescence (PL) spectra showed an emission peak around 430 nm when excited at 350 nm, indicating its potential as a fluorescent drug delivery carrier. In parallel, the cross-shaped M8U6/FM8U6 frameworks were synthesized and characterized using X-ray diffraction, which identified distinct peaks at 2θ = 7.4 (111), 8.5 (200), 9.2 (002), 10.8 (002), 12.1 (220), 16.7 (103), and 17.1 (400). FE-SEM, HR-TEM, and TEM analyses revealed particle sizes of 350±50 nm for M8U6 and 200±50 nm for FM8U6. These frameworks, synthesized from terephthalic acid (H₂BDC), displayed notable vibrational bonds, such as C=O at 1,650 cm⁻¹, Fe-O in MIL-88 at 520 cm⁻¹, and Zr-O in UIO-66 at 482 cm⁻¹. BET analysis showed specific surface areas of 740.1 m²/g with a pore size of 22.92 nm for M8U6 and 493.9 m²/g with a pore size of 35.44 nm for FM8U6. Extended X-ray Absorption Fine Structure (EXAFS) spectra confirmed the stability of Ti-O bonds in the frameworks, with bond lengths of 2.026 Å for MIL-125, 1.962 Å for NH₂-MIL-125, and 1.817 Å for GQD@NH₂-MIL-125. These findings highlight the potential of these organometallic frameworks for enhanced liver cancer therapy through precise drug delivery and imaging, representing a significant advancement in nanomaterial applications in biomedical science. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer%20cells" title="liver cancer cells">liver cancer cells</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20organic%20frameworks" title=" metal organic frameworks"> metal organic frameworks</a>, <a href="https://publications.waset.org/abstracts/search?q=Doxorubicin%20%28DOX%29" title=" Doxorubicin (DOX)"> Doxorubicin (DOX)</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20release." title=" drug release."> drug release.</a> </p> <a href="https://publications.waset.org/abstracts/194174/synthesis-and-characterization-of-ph-sensitive-graphene-quantum-dot-loaded-metal-organic-frameworks-for-targeted-drug-delivery-and-fluorescent-imaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194174.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">8</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">141</span> Reservoir Characterization of the Pre-Cenomanian Sandstone: Central Sinai, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Moktader%20A.%20El%20Sayed">Abdel Moktader A.

The air-side Rea were at 1.8 x 103 to 9.7 x 103. The tubes bundle were employed with various fin height [hf] and fin thickness (δ) from (2 mm ≤ hf ≤ 12 mm) and (1.5 mm ≤ δ ≤ 3.5 mm) respectively at the considered Rea range. The flow pattern around the staggered wing-shaped tubes bundle was predicted using the commercial CFD FLUENT 6.3.26 software package. The distribution of average skin friction coefficient around wing-shaped tubes bundle is studied. Correlation of pressure drop coefficient Pdc and skin friction coefficient (Cf) in terms of Rea, design parameters for the studied cases were presented. Results indicated that the values of Pdc for hf = 6 mm are lower than these of NOF and hf = 2 mm by about 11 % and 13 % respectively for considered Rea range. Cf decreases as Rea increases. LFTH with hf = 6 mm offers lower form drag than that with hf = 12 mm and that of NOF. The lowest values of the pumping power are achieved for arrangements of hf = 6 mm for the considered Rea range. δ has negligible effect on skin friction coefficient, while has a slightly variation in ∆Pa. The wing-shaped tubes bundle heat exchanger with hf = 6 mm has the lowest values of ∆Pa, Pdc, Cf, and pumping power and hence the best performance comparing with the other bundles. Comparisons between the experimental and numerical results of the present study and those obtained by similar previous studies showed good agreements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20fins" title="longitudinal fins">longitudinal fins</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20friction" title=" skin friction"> skin friction</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20characteristics" title=" flow characteristics"> flow characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=FLUENT" title=" FLUENT"> FLUENT</a>, <a href="https://publications.waset.org/abstracts/search?q=wing-shaped%20tubes" title=" wing-shaped tubes"> wing-shaped tubes</a> </p> <a href="https://publications.waset.org/abstracts/35320/effect-of-longitudinal-fins-on-air-flow-characteristics-for-wing-shaped-tubes-in-cross-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35320.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">135</span> Simulation of Pedestrian Service Time at Different Delay Times</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imran%20Badshah">Imran Badshah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pedestrian service time reflects the performance of the facility, and it’s a key parameter to analyze the capability of facilities provided to serve pedestrians. The level of service of pedestrians (LOS) mainly depends on pedestrian time and safety. The pedestrian time utilized by taking a service is mainly influenced by the number of available services and the time utilized by each pedestrian in receiving a service; that is called a delay time. In this paper, we analyzed the simulated pedestrian service time with different delay times. A simulation is performed in AnyLogic by developing a model that reflects the real scenario of pedestrian services such as ticket machine gates at rail stations, airports, shopping malls, and cinema halls. The simulated pedestrian time is determined for various delay values. The simulated result shows how pedestrian time changes with the delay pattern. The histogram and time plot graph of a model gives the mean, maximum and minimum values of the pedestrian time. This study helps us to check the behavior of pedestrian time at various services such as subway stations, airports, shopping malls, and cinema halls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20simulation" title="agent-based simulation">agent-based simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=anylogic%20model" title=" anylogic model"> anylogic model</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20behavior" title=" pedestrian behavior"> pedestrian behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20delay" title=" time delay"> time delay</a> </p> <a href="https://publications.waset.org/abstracts/158989/simulation-of-pedestrian-service-time-at-different-delay-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158989.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">210</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">134</span> Sustainable Traffic Flow: The Case Study of Un-Signalized Pedestrian Crossing at Stationary Bottleneck and Its Impact on Traffic Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imran%20Badshah">Imran Badshah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper study the impact of Un-signalized pedestrian on traffic flow at Stationary Bottleneck. The Highway Capacity Manual (HCM) analyze the methodology of level of service for Urban street segment but it does not include the impact of un-signalized pedestrian crossing at stationary bottleneck. The un-signalized pedestrian crossing in urban road segment causes conflict between vehicles and pedestrians. As a result, the average time taken by vehicle to travel along a road segment increased. The speed of vehicle and the level of service decreases as the running time of a segment increased. To analyze the delay, we need to determine the pedestrian speed while crossing the road at a stationary bottleneck. The objective of this research is to determine the speed of pedestrian and its impact on traffic flow at stationary bottleneck. In addition, the result of this study should be incorporated in the Urban Street Analysis Chapter of HCM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stationary%20bottleneck" title="stationary bottleneck">stationary bottleneck</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20flow" title=" traffic flow"> traffic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20speed" title=" pedestrian speed"> pedestrian speed</a>, <a href="https://publications.waset.org/abstracts/search?q=HCM" title=" HCM"> HCM</a> </p> <a href="https://publications.waset.org/abstracts/159043/sustainable-traffic-flow-the-case-study-of-un-signalized-pedestrian-crossing-at-stationary-bottleneck-and-its-impact-on-traffic-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159043.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">90</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">133</span> Microwave Sanitization of Polyester Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Haggag">K.

Consequently, this study is concerned with improving the quality attributes of gluten-free bread using different concentrations (0, 20, 40, 60 and 80ppm) of all maltogenic α-amylase (MA) and xylanase (XY) compared with wheat flour Balady bread and untreated gluten-free Balady bread (GFBB). Pasting properties, falling number, water activity, alkaline water retention capacity (AWRC) and sensory properties (fresh bread, after 24h, after 48h and after 72h) of gluten-free bread were evaluated. Additionally, the effect of merging different concentrations of maltogenic α-amylase and xylanase on stalling behavior (AWRC) and sensory properties of gluten-free Balady bread was investigated. The addition of MA led to a gradually decreased peak viscosity, breakdown, setback and pasting temperature of GFBB with the increasing level of MA. Maltogenic α-amylase and xylanase addition led to a reduction in the FN values compared to the untreated gluten-free sample, noting that the MA-treated samples showed a significant decrease compared to the XY-treated and untreated samples. Wheat flour Balady bread significantly showed a higher value of AWRC compared to untreated gluten-free Balady bread at different storage periods (zero time, after 24h, after 48h and after 72h). MA-treated samples showed higher water binding capacity and water activity (aw)in comparison with XY-treated samples, with significance during all storage periods. Concerning the overall acceptability during the third day, the highest score (4.6) was observed by the GFBB sample containing 40ppm MA, followed by 4.3, which was investigated by the GFBB sample containing 80ppm XY with no significance between them and with significance compared to the other samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=celiac%20disease" title="celiac disease">celiac disease</a>, <a href="https://publications.waset.org/abstracts/search?q=gluten-free%20products" title=" gluten-free products"> gluten-free products</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-stalling%20agents" title=" anti-stalling agents"> anti-stalling agents</a>, <a href="https://publications.waset.org/abstracts/search?q=maltogenic%20%CE%B1-amylase" title=" maltogenic α-amylase"> maltogenic α-amylase</a>, <a href="https://publications.waset.org/abstracts/search?q=xylanase" title=" xylanase"> xylanase</a> </p> <a href="https://publications.waset.org/abstracts/173389/new-insights-into-gluten-free-bread-staling-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173389.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">84</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">130</span> Microwave-Assisted Eradication of Wool </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Salama">M.

Amelogenesis, the process of enamel formation, is regulated by multiple genes to ensure normal, defect-free enamel. Defective enamel manifests as hypoplasia or as amelogenesis imperfecta (AI), which may occur in isolation or as part of a syndrome. This study presents 29 patients from 18 unrelated families (16 females and 13 males) who exhibited distinctive enamel abnormalities. We conducted thorough clinical examinations and requested laboratory and radiological investigations. Blood samples were collected for molecular analysis, utilizing a targeted panel for known AI variants and whole exome sequencing for unknown variants. Eleven variants linked to enamel anomalies were identified: four genes associated with isolated AI (WDR72, ACP4, SLC24A4, and FAM83H) and seven associated with syndromic forms, including enamel renal syndrome (FAM20A), tricho-dento-osseous syndrome (DLX3), Jalili syndrome (CNNM4), and others linked to neurological and mitochondrial disorders, skeletal dysplasia, and peroxisome disorders. Abnormal oral and dental phenotypes in individuals may indicate serious inherited disorders. Enamel defects have significant implications for aesthetics, function, and patients' psychological well-being. Dental examination, alongside clinical and molecular investigations, is crucial for the accurate diagnosis and prediction of inherited conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amelogenesis%20imperfecta" title="amelogenesis imperfecta">amelogenesis imperfecta</a>, <a href="https://publications.waset.org/abstracts/search?q=enamel%20defect" title=" enamel defect"> enamel defect</a>, <a href="https://publications.waset.org/abstracts/search?q=Enamel%20renal%20syndrome" title=" Enamel renal syndrome"> Enamel renal syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=DLX3" title=" DLX3"> DLX3</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalili%20syndrome" title=" Jalili syndrome"> Jalili syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=WDR72" title=" WDR72"> WDR72</a>, <a href="https://publications.waset.org/abstracts/search?q=FAM83H" title=" FAM83H"> FAM83H</a>, <a href="https://publications.waset.org/abstracts/search?q=whole%20exome%20sequencing" title=" whole exome sequencing"> whole exome sequencing</a> </p> <a href="https://publications.waset.org/abstracts/191884/enamel-structure-defect-the-rare-dental-anomaly-isolated-or-syndromic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191884.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">24</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">128</span> Organotin (IV) Based Complexes as Promiscuous Antibacterials: Synthesis in vitro, in Silico Pharmacokinetic, and Docking Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wajid%20Rehman">Wajid Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirajul%20Haq"> Sirajul Haq</a>, <a href="https://publications.waset.org/abstracts/search?q=Bakhtiar%20Muhammad"> Bakhtiar Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Fahad%20Hassan"> Syed Fahad Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Badshah"> Amin Badshah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Waseem"> Muhammad Waseem</a>, <a href="https://publications.waset.org/abstracts/search?q=Fazal%20Rahim"> Fazal Rahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Obaid-Ur-Rahman%20Abid"> Obaid-Ur-Rahman Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzana%20Latif%20Ansari"> Farzana Latif Ansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Umer%20Rashid"> Umer Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Five novel triorganotin (IV) compounds have been synthesized and characterized. The tin atom is penta-coordinated to assume trigonal-bipyramidal geometry. Using in silico derived parameters; the objective of our study is to design and synthesize promiscuous antibacterials potent enough to combat resistance. Among various synthesized organotin (IV) complexes, compound 5 was found as potent antibacterial agent against various bacterial strains. Further lead optimization of drug-like properties was evaluated through in silico predictions. Data mining and computational analysis were utilized to derive compound promiscuity phenomenon to avoid drug attrition rate in designing antibacterials. Xanthine oxidase and human glucose- 6-phosphatase were found as only true positive off-target hits by ChEMBL database and others utilizing similarity ensemble approach. Propensity towards a-3 receptor, human macrophage migration factor and thiazolidinedione were found as false positive off targets with E-value 1/4> 10^-4 for compound 1, 3, and 4. Further, displaying positive drug-drug interaction of compound 1 as uricosuric was validated by all databases and docked protein targets with sequence similarity and compositional matrix alignment via BLAST software. Promiscuity of the compound 5 was further conﬁrmed by in silico binding to different antibacterial targets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20promiscuity" title=" drug promiscuity"> drug promiscuity</a>, <a href="https://publications.waset.org/abstracts/search?q=ADMET%20prediction" title=" ADMET prediction"> ADMET prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=metallo-pharmaceutical" title=" metallo-pharmaceutical"> metallo-pharmaceutical</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20resistance" title=" antimicrobial resistance"> antimicrobial resistance</a> </p> <a href="https://publications.waset.org/abstracts/17900/organotin-iv-based-complexes-as-promiscuous-antibacterials-synthesis-in-vitro-in-silico-pharmacokinetic-and-docking-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17900.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">503</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">127</span> On Performance of Cache Replacement Schemes in NDN-IoT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasool%20Sadeghi">Rasool Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Mahdi%20Faghih%20Imani"> Sayed Mahdi Faghih Imani</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Najafi"> Negar Najafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The inherent features of Named Data Networking (NDN) provides a robust solution for Internet of Thing (IoT). Therefore, NDN-IoT has emerged as a combined architecture which exploits the benefits of NDN for interconnecting of the heterogeneous objects in IoT. In NDN-IoT, caching schemes are a key role to improve the network performance. In this paper, we consider the effectiveness of cache replacement schemes in NDN-IoT scenarios. We investigate the impact of replacement schemes on average delay, average hop count, and average interest retransmission when replacement schemes are Least Frequently Used (LFU), Least Recently Used (LRU), First-In-First-Out (FIFO) and Random. The simulation results demonstrate that LFU and LRU present a stable performance when the cache size changes. Moreover, the network performance improves when the number of consumers increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NDN-IoT" title="NDN-IoT">NDN-IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=cache%20replacement" title=" cache replacement"> cache replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=ndnSIM" title=" ndnSIM"> ndnSIM</a> </p> <a href="https://publications.waset.org/abstracts/84255/on-performance-of-cache-replacement-schemes-in-ndn-iot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84255.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">365</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">126</span> Similarity Based Membership of Elements to Uncertain Concept in Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kamel%20El-Sayed">M.

The increasing population leads to an increase in demand for food. A large number of crops are infected by different microbes, and nutrient deficiency of soil adversely affects the yield of crops. Furthermore, the use of chemical fertilizers like Nitrogen, Phosphorus, Potassium (NPK) Urea, and Diammonium phosphate (DAP) and pesticides have environmental consequences. Therefore, there is an urgent need to explore alternative renewable and sustainable biofertilizers. Maize is one of the top growing crops in Pakistan, but it has low yield compared to other countries due to deficiency of organic matter, widespread nutrients deficiency (phosphorus and nitrogen), unbalanced use of fertilizers and various fungal diseases. In order to get rid of all these disadvantages, Digestate emerged as a win-win opportunity for the control of a few plant diseases and a replacement for the chemical fertilizers. The present study was designed to investigate the effect of Anerobic digestate on Antifungal Activity and in different parameters of Maize. The antifungal activity, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC) against selected phytopathogens (Colletotrichum coccodis, Pythium ultimum, Phytophthora capsci, Rhizoctonia solani, Bipolaris oryzae and Fusarium Fujikuroi) were determined by microtiter plate method. The effect of various fertilizers in different growth parameters height, diameter, chlorophyll, leaf area, biomass, and yield were studied in field experiments. The extracts from anaerobic digestate have shown antifungal activity against selected phytopathogens, the highest activity was noted against P. ultimum, the MIC activity was high in case of P. ultimum and B. oryzae. The present study concludes that anaerobic digestate have a positive effect on maize growth and yield as well as an antifungal activity which can be potentially a good biofertilizer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestate" title="anaerobic digestate">anaerobic digestate</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title=" antifungal activity"> antifungal activity</a>, <a href="https://publications.waset.org/abstracts/search?q=MIC" title=" MIC"> MIC</a>, <a href="https://publications.waset.org/abstracts/search?q=phytopathogens" title=" phytopathogens"> phytopathogens</a> </p> <a href="https://publications.waset.org/abstracts/105304/investigation-of-the-effect-of-anaerobic-digestate-on-antifungal-activity-and-in-different-parameters-of-maize" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105304.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">125</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">122</span> Steady Conjugate Heat Transfer of Two Connected Thermal Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El-Sayed%20Mosaad">Mohamed El-Sayed Mosaad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An analytic approach is obtained for the steady heat transfer problem of two fluid systems, in thermal communication via heat conduction across a solid wall separating them.

The influence of the various operating parameters on the performance coefficient and exergy efficiency of this cycle has been studied. The results show that when the temperature of different parts increases, the performance coefficient and the exergy efficiency of the cycle decrease, except for evaporator and generator, that causes an increase in coefficient of performance (COP).

Normally in the field, the instrumentations such as ‘diver’ and ‘standpipe’ are to be used to identify the seepage conditions which only provide point data with a fair amount of interpolation or assumption. Here in this paper, we employed high-resolution fiber optic cable sensors (FOCS) based on Raman Scattering in order to obtain a very accurate phreatic line and seepage profile. Unlike the above-mention devices which pinpoint the water level location, this kind of Distributed Fiber Optics Sensing gives us more reliable information due to its inherent characteristics of continuous measurement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=standpipe" title="standpipe">standpipe</a>, <a href="https://publications.waset.org/abstracts/search?q=diver" title=" diver"> diver</a>, <a href="https://publications.waset.org/abstracts/search?q=FOCS" title=" FOCS"> FOCS</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20scattering" title=" Raman scattering"> Raman scattering</a> </p> <a href="https://publications.waset.org/abstracts/61124/ground-water-monitoring-using-high-resolution-fiber-optics-cable-sensors-focs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61124.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">357</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">117</span> A New Floating Point Implementation of Base 2 Logarithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Mansour">Ahmed M.

They are primarily used for hardware calculations, handling multiplications, divisions, powers, and roots effectively. There are three commonly used bases for logarithms; the logarithm with base-10 is called the common logarithm, the natural logarithm with base-e and the binary logarithm with base-2. This paper demonstrates different methods of calculation for log2 showing the complexity of each and finds out the most accurate and efficient besides giving in- sights to their hardware design. We present a new method called Floor Shift for fast calculation of log2, and then we combine this algorithm with Taylor series to improve the accuracy of the output, we illustrate that by using two examples. We finally compare the algorithms and conclude with our remarks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=logarithms" title="logarithms">logarithms</a>, <a href="https://publications.waset.org/abstracts/search?q=log2" title=" log2"> log2</a>, <a href="https://publications.waset.org/abstracts/search?q=floor" title=" floor"> floor</a>, <a href="https://publications.waset.org/abstracts/search?q=iterative" title=" iterative"> iterative</a>, <a href="https://publications.waset.org/abstracts/search?q=CORDIC" title=" CORDIC"> CORDIC</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%20series" title=" Taylor series "> Taylor series </a> </p> <a href="https://publications.waset.org/abstracts/15224/a-new-floating-point-implementation-of-base-2-logarithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15224.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">531</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">116</span> Protein-Thiocyanate Composite as a Sensor for Iron III Cations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hosam%20El-Sayed">Hosam El-Sayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20%20Abou%20El-Kheir"> Amira Abou El-Kheir</a>, <a href="https://publications.waset.org/abstracts/search?q=Salwa%20Mowafi"> Salwa Mowafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Abou%20Taleb"> Marwa Abou Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two proteinic biopolymers; namely keratin and sericin, were extracted from their respective natural resources by simple appropriate methods. The said proteins were dissolved in the appropriate solvents followed by regeneration in a form of film polyvinyl alcohol. Proteinium thiocyanate (PTC) composite was prepared by reaction of a regenerated film with potassium thiocyanate in acid medium. In another experiment, the said acidified proteins were reacted with potassium thiocyante before dissolution and regeneration in a form of PTC composite. The possibility of using PTC composite for determination of the concentration of iron III ions in domestic as well as industrial water was examined. The concentration of iron III cations in water was determined spectrophotometrically by measuring the intensity of blood red colour of iron III thiocyanate obtained by interaction of PTC with iron III cation in the tested water sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron%20III%20cations" title="iron III cations">iron III cations</a>, <a href="https://publications.waset.org/abstracts/search?q=protein" title=" protein"> protein</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=thiocyanate" title=" thiocyanate"> thiocyanate</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a> </p> <a href="https://publications.waset.org/abstracts/52322/protein-thiocyanate-composite-as-a-sensor-for-iron-iii-cations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52322.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">429</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">115</span> Integrated Model for Enhancing Data Security Performance in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20A.%20Saad">Amani A.

Cloud computing allows sharing resources, services and information among the people of the whole world. Although the advantages of using clouds are great, but there are many risks in a cloud. The data security is the most important and critical problem of cloud computing. In this research a new security model for cloud computing is proposed for ensuring secure communication system, hiding information from other users and saving the user's times. In this proposed model Blowfish encryption algorithm is used for exchanging information or data, and SHA-2 cryptographic hash algorithm is used for data integrity. For user authentication process a user-name and password is used, the password uses SHA-2 for one way encryption. The proposed system shows an improvement of the processing time of uploading and downloading files on the cloud in secure form. <p class="card-text"><strong>Keywords:</strong> <a
