The parasite responsible for the vast majority of fatal malaria infections is Plasmodium falciparum. Unfortunately, most Plasmodium strains including P. falciparum have become resistant to most of the antimalarials including chloroquine, mefloquine, etc. To combat this problem, WHO has recommended the use of artemisinin and its derivatives in artemisinin based combination therapy (ACT). Due to its current use in artemisinin based-combination therapy (ACT), its global demand is increasing continuously. But, the relatively low yield of artemisinin in A. annua L. plants and unavailability of economically viable synthetic protocols are the major bottlenecks for its commercial production and clinical use. Chemical synthesis of artemisinin is also very complex and uneconomical. The hairy root system, using the Agrobacterium rhizogenes LBA 9402 strain to enhance the production of artemisinin in A. annua L., is developed in our laboratory. The transgenic nature of hairy root lines and the copy number of trans gene (rol B) were confirmed using PCR and Southern Blot analyses, respectively. The effect of different concentrations of Piriformospora indica on artemisinin production in hairy root cultures were evaluated. 3% P. indica has resulted 1.97 times increase in artemisinin production in comparison to control cultures. The effects of P. indica on artemisinin production was positively correlated with regulatory genes of MVA, MEP and artemisinin biosynthetic pathways, viz. hmgr, ads, cyp71av1, aldh1, dxs, dxr and dbr2 in hairy root cultures of A. annua L. Mass scale cultivation of A. annua L. hairy roots by plant tissue culture technology may be an alternative route for production of artemisinin. A comprehensive investigation of the hairy root system of A. annua L. would help in developing a viable process for the production of artemisinin. The efficiency of the scaling up systems still needs optimization before industrial exploitation becomes viable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20annua%20L." title="A. annua L.">A. annua L.</a>, <a href="https://publications.waset.org/abstracts/search?q=artemisinin" title=" artemisinin"> artemisinin</a>, <a href="https://publications.waset.org/abstracts/search?q=hairy%20root%20cultures" title=" hairy root cultures"> hairy root cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=malaria" title=" malaria"> malaria</a> </p> <a href="https://publications.waset.org/abstracts/22980/improvement-of-artemisinin-production-by-p-indica-in-hairy-root-cultures-of-a-annua-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22980.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">415</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">2049</span> Implications of Oxidative Stress for Monoterpenoid Oxindole Alkaloid Production in Uncaria tomentosa Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20C.%20Ramos%20Valdivia">Ana C.

A limited number of species of plants like Uncaria tomentosa (cat claw) typical of the Amazon region produce monoterpenoid oxindole alkaloids (MOA) such as isopteropodine, mitraphylline, rhynchophylline and its isomers. Moreover, in cultivated roots, the glucoindole alkaloid 3α-dihydrocadambine (DHC) is also accumulated. Several studies have demonstrated that MAO has antioxidant properties and possess important pharmacological activities such as antitumor and immunostimulant while DHC, has hypotensive and hypolipidemic effects. In order the study the regulatory concerns operating in MAO production, the links between oxidative stress and antioxidant alkaloid production in U. tomentosa root cultures were examined. Different amount of hydrogen peroxide between 0.2 -1.0 mM was added to 12 days old roots cultures showing that, this substance had a differential effect on the production of DHC and MOA whereas the viability remained in 80% after six days. Addition of 0.2 mM hydrogen peroxide increased approximately 65% MAO and DHC production (0,540 ± 0.018 and 0.618 ± 0.029 mg per g dry weight, respectively) relative to the control. On contrast, after the addition of 0.6 mM and 1 mM hydrogen peroxide, DHC accumulation into the roots gradually decreased to 53% and 93% respectively, without changes in MAO concentration, which was in relation to a twice increase of the intracellular hydrogen peroxide content. On the other hand, concentrations of DHC (0.1, 0.5 and 1.0 mM in methanol) demonstrated free-radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The calculated IC50 for all tested concentrations was 0.180 mg per ml (0.33 mM) while the calculated TE50 was 276 minutes. Our results suggest that U. tomentosa root cultures both MAO and DHC have antioxidant capacities and respond to oxidative stress with a stimulation of their production; however, in presence of a higher concentration of ROS into the roots, DHC could be oxidized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monoterpenoid%20indole%20alkaloid" title="monoterpenoid indole alkaloid">monoterpenoid indole alkaloid</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20cultures" title=" root cultures"> root cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=uncaria%20tomentosa" title=" uncaria tomentosa"> uncaria tomentosa</a> </p> <a href="https://publications.waset.org/abstracts/71305/implications-of-oxidative-stress-for-monoterpenoid-oxindole-alkaloid-production-in-uncaria-tomentosa-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71305.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">182</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">2048</span> Mechanisms of Cultural Change Resistance through Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Horaya%20Mostafa%20Ahmed">Horaya Mostafa Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All cultures are inherently predisposed to change and, at the same time, to resisting change. There are dynamic processes operating that encourage the acceptance of new ideas and things, while there are others that encourage changeless stability. Despite the dramatic changes that have taken place in all human cultures, there are cultures still steadfast and resist change. These cultures resist through some culture mechanisms like, cultural boundaries, ethnocentrism, religion, and cultural relativity.

This work was planned with four replications at a Completely Randomized Block Design in 2011-2012 growing season. In the study, root biomass growth was evaluated at stages of stem elongation, complete of anthesis and full grain maturity. Results showed that there were significant differences between cultivars grown at dry and irrigated lands in all growth stages in terms of root biomass (P < 0.01). According to research results, all of growth stages, dry typed-bread and durum wheats generally had higher root biomass than irrigated typed-cultivars, furthermore that dry typed-barley cultivar, had higher root biomass at GS 31 and GS 69, however lower at GS 92 than Larende. In all cultivars, root biomass increased between GS 31 and GS 69 so that dry typed-cultivars had more root biomass increase than irrigated typed-cultivars. Root biomass of bread wheat increased between GS 69 and GS 92, however root biomass of barley and durum wheat decreased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bread%20and%20durum%20wheat" title="bread and durum wheat">bread and durum wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=barley" title=" barley"> barley</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20biomass" title=" root biomass"> root biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=different%20growth%20stage" title=" different growth stage"> different growth stage</a> </p> <a href="https://publications.waset.org/abstracts/20561/root-biomass-growth-in-different-growth-stages-of-wheat-and-barley-cultivars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20561.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">606</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">2046</span> Optimization of Tooth Root Profile and Drive Side Pressure Angle to Minimize Bending Stress at Root of Asymmetric Spur Gear Tooth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyakant%20Vaghela">Priyakant Vaghela</a>, <a href="https://publications.waset.org/abstracts/search?q=Jagdish%20Prajapati"> Jagdish Prajapati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bending stress at the root of the gear tooth is the very important criteria in gear design and it should be kept the minimum. Minimization of bending stress at the root of the gear tooth is a recent demand from industry. This paper presents an innovative approach to obtain minimum bending stress at the root of a tooth by optimizing tooth root profile and drive side pressure angle. Circular-filleted at the root of the tooth is widely used in the design. Circular fillet creates discontinuity at the root of the tooth. So, at root stress concentration occurs. In order to minimize stress concentration, an important criterion is a G2 continuity at the blending of the gear tooth. A Bezier curve is used with G2 continuity at the root of asymmetric spur gear tooth. The comparison has been done between normal and modified tooth using ANSYS simulation. Tooth root profile and drive side pressure angle are optimized to minimize bending stress at the root of the tooth of the asymmetric involute spur gear. Von Mises stress of optimized profile is analyzed and compared with normal profile symmetric gear. Von Mises stress is reducing by 31.27% by optimization of drive side pressure angle and root profile. Stress concentration of modified gear was significantly reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20spur%20gear%20tooth" title="asymmetric spur gear tooth">asymmetric spur gear tooth</a>, <a href="https://publications.waset.org/abstracts/search?q=G2%20continuity" title=" G2 continuity"> G2 continuity</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20angle" title=" pressure angle"> pressure angle</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20concentration%20at%20the%20root%20of%20tooth" title=" stress concentration at the root of tooth"> stress concentration at the root of tooth</a>, <a href="https://publications.waset.org/abstracts/search?q=tooth%20root%20stress" title=" tooth root stress"> tooth root stress</a> </p> <a href="https://publications.waset.org/abstracts/95043/optimization-of-tooth-root-profile-and-drive-side-pressure-angle-to-minimize-bending-stress-at-root-of-asymmetric-spur-gear-tooth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95043.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">186</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">2045</span> Unit Root Tests Based On the Robust Estimator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wararit%20Panichkitkosolkul">Wararit Panichkitkosolkul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p class="Abstract" style="text-indent:10.2pt">The unit root tests based on the robust estimator for the first-order autoregressive process are proposed and compared with the unit root tests based on the ordinary least squares (OLS) estimator.

Eighty single-rooted extracted human teeth were endodontically treated, apicectomised and randomly divided into four following groups (n = 20): US/MTA, US/NEC, L/MTA and L/NEC. In US/MTA and US/NEC groups, rooted cavities were prepared with ultrasonic retrotip and filled with MTA and NEC, respectively. In L/MTA and L/NEC groups, root-end cavities were prepared using Er, Cr:YSGG laser and filled with MTA and NEC, respectively. Each root was cut apically to create a 2 mm-thick root slice for measurement of bond strength using a universal testing machine. Then, all slices were examined to determine the mode of bond failure. Data were analysed using two-way ANOVA. Root-end filling materials showed significantly higher bond strength in root-end cavities prepared using the ultrasonic technique (US/MTA and US/NEC) (P < 0.001). The bond strengths of MTA and NEC did not differ significantly. The failure modes were mainly adhesive for MTA, but cohesive for NEC. In conclusion, bond strengths of MTA and NEC to root-end cavities were comparable and higher in ultrasonically prepared cavities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20strength" title="bond strength">bond strength</a>, <a href="https://publications.waset.org/abstracts/search?q=Er" title=" Er"> Er</a>, <a href="https://publications.waset.org/abstracts/search?q=Cr%3AYSGG%20laser" title="Cr:YSGG laser">Cr:YSGG laser</a>, <a href="https://publications.waset.org/abstracts/search?q=MTA" title=" MTA"> MTA</a>, <a href="https://publications.waset.org/abstracts/search?q=NEC" title=" NEC"> NEC</a>, <a href="https://publications.waset.org/abstracts/search?q=root-end%20cavity" title=" root-end cavity"> root-end cavity</a> </p> <a href="https://publications.waset.org/abstracts/17770/push-out-bond-strength-of-two-root-end-filling-materials-in-root-end-cavities-prepared-by-ercr-ysgg-laser-or-ultrasonic-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17770.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">345</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">2043</span> Introgression of Improved Root Biomass Traits into Wheat Hybrids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20N.%20U.%20Abdullah">F.

An initial wheat root study with Winrhizo scanner showed that entries with high root surface area but narrow root angle are associated with past drought tolerance in Texas, while those with wide angle can perform best under normal growing conditions. In a hybrid field experiment, commercial heterosis up to 8.3% in grain yield was obtained from diverse parents selected from male and female diverse groups. These hybrids showed promising yield at Greenville and McGregor, Texas, with grain yield up to 4412 Kg ha⁻¹ as compared to best performing commercial varieties ‘TAM-304’ (4075 Kg ha⁻¹) and ‘Gallagher’ (3981 Kg ha⁻¹). Among 130 hybrids produced, a subset of 50 better-performing hybrids and parents was subjected to one-month-old plant root studies scanned with Winrhizo. The results showed a significant positive correlation of grain yield with initial root angle and a negative correlation with root length. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrids" title="hybrids">hybrids</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20studies" title=" root studies"> root studies</a>, <a href="https://publications.waset.org/abstracts/search?q=heterosis" title=" heterosis"> heterosis</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat%20breeding" title=" wheat breeding"> wheat breeding</a> </p> <a href="https://publications.waset.org/abstracts/183018/introgression-of-improved-root-biomass-traits-into-wheat-hybrids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183018.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">60</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">2042</span> Human Errors in IT Services, HFACS Model in Root Cause Categorization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kari%20Saarelainen">Kari Saarelainen</a>, <a href="https://publications.waset.org/abstracts/search?q=Marko%20Jantti"> Marko Jantti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> IT service trending of root causes of service incidents and problems is an important part of proactive problem management and service improvement. Human error related root causes are an important root cause category also in IT service management, although it’s proportion among root causes is smaller than in the other industries. The research problem in this study is: How root causes of incidents related to human errors should be categorized in an ITSM organization to effectively support service improvement. Categorization based on IT service management processes and based on Human Factors Analysis and Classification System (HFACS) taxonomy was studied in a case study. HFACS is widely used in human error root cause categorization across many industries.

We prepared two extracts of B. tinctoria; one in water and the other in 50% ethanol. Then we evaluated the toxicities of the B. tinctoria root extracts at 10 to 100 mg mL-1 concentrations in raw 264.7 cells and observed 80% cell viability. The anti-inflammatory effect of B. tinctoria root extract in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells were observed with concentrations at 10, 30, and 50 μg mL-1. The results showed that 77.27-66.82% of nitric oxide (NO) production was inhibited by 50 μg mL-1 B. tinctoria root extract. The protein expression of Inducible NO synthase (iNOS) expression dramatically decreased by 93.14% and 52.65% in raw 264.7 cells treated with water and ethanol extracts of B. tinctoria root, respectively. Moreover, cyclooxygenase-2 (COX-2) protein expression decreased by 42.85% and 69.70% in raw 264.7 cells treated with water and ethanol extracts of B. tinctoria root, respectively. Furthermore, the mRNA expression of pro-inflammatory markers, such as tumor necrosis factor-alpha, interleukin-1β, interleukin-6, monocyte chemoattractant protein-1, and prostaglandin E synthase 2, was significantly suppressed in a concentration-dependent manner. Additionally, the B. tinctoria root extracts effectively inhibited enzymes involved in physiological activities. The B. tinctoria root extracts showed excellent anti-inflammatory effects and can be used as a functional material for biological activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytokine" title="cytokine">cytokine</a>, <a href="https://publications.waset.org/abstracts/search?q=macrophage" title=" macrophage"> macrophage</a>, <a href="https://publications.waset.org/abstracts/search?q=pro-inflammatory" title=" pro-inflammatory"> pro-inflammatory</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20expression" title=" protein expression"> protein expression</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20PCR" title=" real-time PCR"> real-time PCR</a> </p> <a href="https://publications.waset.org/abstracts/162103/anti-inflammatory-effect-of-wild-indigo-baptisia-tinctoria-root-on-raw-2647-cells-with-stimulated-lipopolysaccharide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162103.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">71</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">2038</span> Root System Architecture Analysis of Sorghum Genotypes and Its Effect on Drought Adaptation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hailemariam%20Solomon">Hailemariam Solomon</a>, <a href="https://publications.waset.org/abstracts/search?q=Taye%20Tadesse"> Taye Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Nadew"> Daniel Nadew</a>, <a href="https://publications.waset.org/abstracts/search?q=Firezer%20Girma"> Firezer Girma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sorghum is an important crop in semi-arid regions and has shown resilience to drought stress. However, recurrent drought is affecting its productivity. Therefore, it is necessary to explore genes that contribute to drought stress adaptation to increase sorghum productivity. The aim of this study is to evaluate and determine the effect of root system traits, specifically root angle, on drought stress adaptation and grain yield performance in sorghum genotypes. A total of 428 sorghum genotypes from the Ethiopian breeding program were evaluated in three drought-stress environments. Field trials were conducted using a row-column design with three replications. Root system traits were phenotyped using a high-throughput phenotyping platform and analyzed using a row-column design with two replications. Data analysis was performed using R software and regression analysis. The study found significant variations in root system architecture among the sorghum genotypes. Non-stay-green genotypes had a grain yield ranging from 1.63 to 3.1 tons/ha, while stay-green genotypes had a grain yield ranging from 2.4 to 2.9 tons/ha. The analysis of root angle showed that non-stay-green genotypes had an angle ranging from 8.0 to 30.5 degrees, while stay-green genotypes had an angle ranging from 12.0 to 29.0 degrees. Improved varieties exhibited angles between 14.04 and 19.50 degrees. Positive and significant correlations were observed between leaf areas and shoot dry weight, as well as between leaf width and shoot dry weight. Negative correlations were observed between root angle and leaf area, as well as between root angle and root length. This research highlights the importance of root system architecture, particularly root angle traits, in enhancing grain yield production in drought-stressed conditions. It also establishes an association between root angle and grain yield traits for maximizing sorghum productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roor%20sysytem%20architecture" title="roor sysytem architecture">roor sysytem architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20angle" title=" root angle"> root angle</a>, <a href="https://publications.waset.org/abstracts/search?q=narrow%20root%20angle" title=" narrow root angle"> narrow root angle</a>, <a href="https://publications.waset.org/abstracts/search?q=wider%20root%20angle" title=" wider root angle"> wider root angle</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a> </p> <a href="https://publications.waset.org/abstracts/170823/root-system-architecture-analysis-of-sorghum-genotypes-and-its-effect-on-drought-adaptation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170823.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">75</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">2037</span> Effect of Different Salt Concentrations and Temperatures on Seed Germination and Seedling Characters in Safflower (Carthamus tinctorius L.)

The main aim of this study is to investigate the mechanical effect of analogue root systems on the shear strength of different soil types. Three objectives were defined to achieve the main aim of this paper. Firstly, explore the effect of root architectural design to shear strength parameters. Secondly, study the effect of root area ratio (RAR) on the shear strength of two different soil types. Finally, to investigate how different kinds of soil can affect the behavior of the roots during shear failure. 3D printing tool was used to develop different analogue tap root models with different architectural designs. Direct shear tests were performed on Leighton Buzzard (LB) fraction B sand, which represents a coarse sand and Huston sand, which represent medium-coarse sand. All tests were done with the same relative density for both kinds of sand. The results of the direct shear test indicated that using plant roots will increase both friction angle and cohesion of soil. Additionally, different root designs affected differently the shear strength of the soil. Furthermore, the directly proportional relationship was found between root area ratio for the same root design and shear strength parameters of soil. Finally, the root area ratio effect should be combined with branches penetrating the shear plane to get the highest results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leighton%20buzzard%20sand" title="leighton buzzard sand">leighton buzzard sand</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20area%20ratio" title=" root area ratio"> root area ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=rooted%20soil" title=" rooted soil"> rooted soil</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strength" title=" shear strength"> shear strength</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stabilization" title=" slope stabilization"> slope stabilization</a> </p> <a href="https://publications.waset.org/abstracts/122599/investigate-the-mechanical-effect-of-different-root-analogue-models-to-soil-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122599.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">152</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">2035</span> Fu Hao From the East: Between Chinese Traditions and Western Pop Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yi%20Meng">Yi Meng</a>, <a href="https://publications.waset.org/abstracts/search?q=YunGao"> YunGao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Having been studied and worked in North America and Europe, we, two Chinese art educators, have been enormously influenced by eastern and western cultures.

Instead of relying on the predominant western observational drawing skills in our classroom, we taught students about ancient Chinese art in the provincial museum, using Fu Hao owl-shaped vessel, a Shang Dynasty national treasure, as the final sketch project of this course. We took up multimodal literacy, which emphasized students’ critical use of creativity to exploit the semiotic potentials of communicative modes to address diverse cultural issues through their multimodal design. We used the Hong Kong-based artist Tik Ka’s artworks to demonstrate the cultural amalgamation of Chinese traditions and western pop cultures. Collectively, these approaches create a dialogical space for students to experience, analyze, and negotiate with complex modes and potentially transform their understanding of both cultures by redesigning Fu Hao. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chinese%20traditions" title="Chinese traditions">Chinese traditions</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20pop%20cultures" title=" western pop cultures"> western pop cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu%20Hao" title=" Fu Hao"> Fu Hao</a>, <a href="https://publications.waset.org/abstracts/search?q=arts%20education" title=" arts education"> arts education</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20sketch" title=" design sketch"> design sketch</a> </p> <a href="https://publications.waset.org/abstracts/160082/fu-hao-from-the-east-between-chinese-traditions-and-western-pop-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160082.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">119</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">2034</span> Genetic Divergence Study of Rice on the Basis of Various Morphological Traits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ashfaq">Muhammad Ashfaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saleem%20Haider"> Muhammad Saleem Haider</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali"> Muhammad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sajjad"> Muhammad Sajjad</a>, <a href="https://publications.waset.org/abstracts/search?q=Amna%20Ali"> Amna Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Urooj%20Mubashar"> Urooj Mubashar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phenotypic diversity was confirmed by measuring different morphological traits i.e. seed traits (seed length, seed width, seed thickness, seed length-width ratio, 1000 grain weight) and root-shoot traits (shoot length, root length, shoot fresh weight, root fresh weight, root-shoot ratio, root numbers and root thickness). Variance and association study of desirable traits determine the genotypic differences among the rice germplasm. All the traits showed significant differences among the genotypes. The traits were studied in Randomized complete block design (RCBD) at different water levels. Some traits showed positive correlation with each other and beneficial for increasing the yield and production of the crop. Seed thickness has positive correlation with seed length and seed width (r= 0.104**, r=0.246**). On the other hand, various root shoot traits showed positive highly significant association at different water levels i.e. root length, fresh root weight, root thickness, shoot thickness and root numbers.

The main objective of this study is to screen out the genotypes on the basis of various genotypic and phenotypic traits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rice" title="rice">rice</a>, <a href="https://publications.waset.org/abstracts/search?q=morphological%20traits" title=" morphological traits"> morphological traits</a>, <a href="https://publications.waset.org/abstracts/search?q=association" title=" association"> association</a>, <a href="https://publications.waset.org/abstracts/search?q=germplasm" title=" germplasm"> germplasm</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20levels" title=" water levels"> water levels</a>, <a href="https://publications.waset.org/abstracts/search?q=variation" title=" variation"> variation</a> </p> <a href="https://publications.waset.org/abstracts/53359/genetic-divergence-study-of-rice-on-the-basis-of-various-morphological-traits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53359.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">321</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">2033</span> Security Design of Root of Trust Based on RISC-V</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kang%20Huang">Kang Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wanting%20Zhou"> Wanting Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiwei%20Yuan"> Shiwei Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Li"> Lei Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since information technology develops rapidly, the security issue has become an increasingly critical for computer system. In particular, as cloud computing and the Internet of Things (IoT) continue to gain widespread adoption, computer systems need to new security threats and attacks. The Root of Trust (RoT) is the foundation for providing basic trusted computing, which is used to verify the security and trustworthiness of other components. Design a reliable Root of Trust and guarantee its own security are essential for improving the overall security and credibility of computer systems. In this paper, we discuss the implementation of self-security technology based on the RISC-V Root of Trust at the hardware level. To effectively safeguard the security of the Root of Trust, researches on security safeguard technology on the Root of Trust have been studied. At first, a lightweight and secure boot framework is proposed as a secure mechanism. Secondly, two kinds of memory protection mechanism are built to against memory attacks. Moreover, hardware implementation of proposed method has been also investigated. A series of experiments and tests have been carried on to verify to effectiveness of the proposed method. The experimental results demonstrated that the proposed approach is effective in verifying the integrity of the Root of Trust’s own boot rom, user instructions, and data, ensuring authenticity and enabling the secure boot of the Root of Trust’s own system. Additionally, our approach provides memory protection against certain types of memory attacks, such as cache leaks and tampering, and ensures the security of root-of-trust sensitive information, including keys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=root%20of%20trust" title="root of trust">root of trust</a>, <a href="https://publications.waset.org/abstracts/search?q=secure%20boot" title=" secure boot"> secure boot</a>, <a href="https://publications.waset.org/abstracts/search?q=memory%20protection" title=" memory protection"> memory protection</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware%20security" title=" hardware security"> hardware security</a> </p> <a href="https://publications.waset.org/abstracts/164581/security-design-of-root-of-trust-based-on-risc-v" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164581.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">216</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">2032</span> Iron Influx, Its Root-Shoot Relations and Utilization Efficiency in Wheat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Malik%20Dawlatzai">Abdul Malik Dawlatzai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafiqullah%20Rahmani"> Shafiqullah Rahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant cultivars of the same species differ in their Fe efficiency. This paper studied the Fe influx and root-shoot relations of Fe at different growth stages in wheat. The four wheat cultivars (HD 2967, PDW 233, PBW 550 and PDW 291) were grown in pots in Badam Bagh agricultural researching farm, Kabul under two Fe treatments: (i) 0 mg Fe kg⁻¹ soil (soil with 2.7 mg kg⁻¹ of DTPA-extractable Fe) and (ii) 50 mg Fe kg⁻¹ soil. Root length (RL), shoot dry matter (SDM), Fe uptake, and soil parameters were measured at tillering and anthesis. Application of Fe significantly increased RL, root surface area, SDM, and Fe uptake in all wheat cultivars. Under Fe deficiency, wheat cv. HD 2967 produced 90% of its maximum RL and 75% of its maximum SDM. However, PDW 233 produced only 69% and 60%, respectively. Wheat cultivars HD 2967, and PDW 233 exhibited the highest and lowest value of root surface area and Fe uptake, respectively. The concentration difference in soil solution Fe between bulk soil and root surface (ΔCL) was maximum in wheat cultivar HD 2967, followed by PBW 550, PDW 291, and PDW 233. More depletion at the root surface causes steeper concentration gradients, which result in a high influx and transport of Fe towards root. Fe influx in all the wheat cultivars increased with the Fe application, but the increase was maximum, i.e., 4 times in HD 2967 and minimum, i.e., 2.8 times in PDW 233. It can be concluded that wheat cultivars HD 2967 and PBW 550 efficiently utilized Fe as compared to other cultivars. Additionally, iron efficiency of wheat cultivars depends upon uptake of each root segment, i.e., the influx, which in turn depends on depletion of Fe in the rhizosphere during vegetative phase and higher utilization efficiency of acquired Fe during reproductive phase that governs the ultimate grain yield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fe%20efficiency" title="Fe efficiency">Fe efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%20influx" title=" Fe influx"> Fe influx</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%20uptake" title=" Fe uptake"> Fe uptake</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhizosphere" title=" Rhizosphere"> Rhizosphere</a> </p> <a href="https://publications.waset.org/abstracts/128052/iron-influx-its-root-shoot-relations-and-utilization-efficiency-in-wheat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128052.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">132</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">2031</span> RACK1 Integrates Light and Brassinosteroid Signaling to Coordinate Cell Division During Root Soil Penetration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liang%20%20Jiansheng">Liang Jiansheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhu%20Wei"> Zhu Wei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Light and brassinosteroids are essential external and internal cues for plant survival. Although the coordination of light with phytohormone signals is crucial for plant growth and development, the molecular connection between light and brassinosteroid signaling during root soil penetration remains elusive. Here, we reveal that light-stabilized RACK1 couples a brassinosteroid signaling cascade to drive cell division in root meristems. RACK1 family scaffold proteins positively regulate light-induced the promotion of root elongation during soil penetration. Under the light condition, RACK1A interacts with both phyB and SPA1, then reinforces the phyB-SPA1 association to accumulate its abundance in roots. In response to brassinosteroid signals, RACK1A competes with BKI1 to attenuate the BRI1-BKI1 interaction, thereby leading to activating BRI1 actions in root development. Furthermore, RACK1A binds to BES1 to repress its DNA binding activity toward the target gene CYCD3;1. This ultimately allows to release the inhibition of CYCD3;1 transcription, and promotes cell division during root growth. Our study illustrates a new mechanistic model of how plants engage scaffold proteins in transducing light information to facilitate brassinosteroid signaling for root growth in the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=root%20growth" title="root growth">root growth</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20division" title=" cell division"> cell division</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20signaling" title=" light signaling"> light signaling</a>, <a href="https://publications.waset.org/abstracts/search?q=brassinosteroid%20signaling" title=" brassinosteroid signaling"> brassinosteroid signaling</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20penetration" title=" soil penetration"> soil penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold%20protein" title=" scaffold protein"> scaffold protein</a>, <a href="https://publications.waset.org/abstracts/search?q=RACK1" title=" RACK1"> RACK1</a> </p> <a href="https://publications.waset.org/abstracts/171045/rack1-integrates-light-and-brassinosteroid-signaling-to-coordinate-cell-division-during-root-soil-penetration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171045.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">80</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">2030</span> Evaluation of the Safety and Performance of Blood Culture Practices Using BD Safety-Lokᵀᴹ Blood Collection Sets in the Emergency Room</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeonghyun%20Chang">Jeonghyun Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Taegeun%20Lee"> Taegeun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Heungsup%20Sung"> Heungsup Sung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoon-Seon%20Lee"> Yoon-Seon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Youn-Jung%20Kim"> Youn-Jung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Na%20Kim"> Mi-Na Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Safety device has been applied to improve safety and performance of blood culture practice. BD vacutainer® Safety-Lokᵀᴹ blood collection sets with pre-attached holder (Safety-Lok) (BD, USA) was evaluated in the emergency room (ER) of a tertiary care hospital. Methods: From April to June 2017, interns and nurses in ER were surveyed for blood culture practices with a questionnaire before and after 2 or 3 weeks of experience of Safety-Lok. All of them participated in exercise workshop for 1 hour combined with video education prior to the initial survey. The blood volume, positive and contamination rates of Safety-Lok-drawn (SD) blood cultures were compared to those of overall blood cultures. Results: Eighteen interns and 30 nurses were enrolled. As a result of the initial survey, interns had higher rates of needlestick incidence (27.8%), carriage of the blood-filled syringe with needle (88.9%) and lower rates of vacutainer use (38.9%) than nurses (13.3%, 53.3%, and 60.0%). Interns preferred to use safety devices (88.9%) rather than nurses (40.0%). The number of overall blood cultures and SD blood cultures was 9,053 and 555, respectively. While the overall blood volume of aerobic bottles was 2.6±2.1 mL, those of SD blood cultures were 5.0±3.0 mL in aerobic bottles and 6.0±3.0 mL in anaerobic bottles. Positive and contamination rates were 6.5% and 0.72% with SD blood cultures and 6.2% and 0.3% with overall blood cultures. Conclusions: The introduction of the safety device would encourage healthcare workers to collect adequate blood volume as well as lead to safer practices in the ER. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20culture" title="blood culture">blood culture</a>, <a href="https://publications.waset.org/abstracts/search?q=needlestick" title=" needlestick"> needlestick</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20device" title=" safety device"> safety device</a>, <a href="https://publications.waset.org/abstracts/search?q=volume" title=" volume"> volume</a> </p> <a href="https://publications.waset.org/abstracts/90313/evaluation-of-the-safety-and-performance-of-blood-culture-practices-using-bd-safety-lok-blood-collection-sets-in-the-emergency-room" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90313.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">207</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">2029</span> Exploring Selected Cultures in Mitigating an Array of Social Vices in South Africa: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kang%27ethe%20Simon">M.

The article uses a review of literature methodology. Findings indicate that Africans were hoodwinked by white people to abandon their cultures for western based cultures. African cultures continue to weaken as they succumb to forces of westernization, eurocentrism, modernization, civilization, and globalization. Africans have realised that their cultures abandoned such as virginity testing, sexual mores and taboos and circumcision could be a panacea in mitigating some of the societal ills such as moral decadence and HIV/AIDS. The article urges for a resuscitation of cultural practices such as virginity testing, thigh sex (ukumetsha), circumcision and teachings that accompanied initiation schools; and societies to undergo an attitudinal and cultural paradigm shift that will consider the invaluable aspects of cultures that can effectuate and facilitate mitigation of social ills in African countries such as South Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virginity%20testing%20%28reed%20dance%29" title="virginity testing (reed dance)">virginity testing (reed dance)</a>, <a href="https://publications.waset.org/abstracts/search?q=circumcision" title=" circumcision"> circumcision</a>, <a href="https://publications.waset.org/abstracts/search?q=initiation%20schools" title=" initiation schools"> initiation schools</a>, <a href="https://publications.waset.org/abstracts/search?q=African%20Renaissance" title=" African Renaissance"> African Renaissance</a>, <a href="https://publications.waset.org/abstracts/search?q=thigh%20sex" title=" thigh sex"> thigh sex</a>, <a href="https://publications.waset.org/abstracts/search?q=moral%20decadence" title=" moral decadence"> moral decadence</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20custodians" title=" cultural custodians"> cultural custodians</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20of%20anomie" title=" state of anomie"> state of anomie</a> </p> <a href="https://publications.waset.org/abstracts/11650/exploring-selected-cultures-in-mitigating-an-array-of-social-vices-in-south-africa-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11650.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">495</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">2028</span> Shift in the Rhizosphere Soil Fungal Community Associated with Root Rot Infection of Plukenetia Volubilis Linneo Caused by Fusarium and Rhizopus Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Constantine%20Uwaremwe">Constantine Uwaremwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenjie%20Bao"> Wenjie Bao</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Goudia%20Daoura"> Bachir Goudia Daoura</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandhya%20Mishra"> Sandhya Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Xianxian%20Zhang"> Xianxian Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingjie%20Shen"> Lingjie Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shangwen%20Xia"> Shangwen Xia</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaodong%20Yang"> Xiaodong Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Plukenetia volubilis Linneo is an oleaginous plant belonging to the family Euphorbiaceae. Due to its seeds containing a high content of edible oil and rich in vitamins, P. volubilis is cultivated as an economical plant worldwide. However, the cultivation and growth of P. volubilis is challenged by phytopathogen invasion leading to production loss. Methods: In the current study, we tested the pathogenicity of fungal pathogens isolated from root rot infected P. volubilis plant tissues by inoculating them into healthy P. volubilis seedlings. Metagenomic sequencing was used to assess the shift in the fungal community of P. volubilis rhizosphere soil after root rot infection. Results: Four Fusarium isolates and two Rhizopus isolates were found to be root rot causative agents of P. volubilis as they induced typical root rot symptoms in healthy seedlings. The metagenomic sequencing data showed that root rot infection altered the rhizosphere fungal community. In root rot infected soil, the richness and diversity indices increased or decreased depending on pathogens. The four most abundant phyla across all samples were Ascomycota, Glomeromycota, Basidiomycota, and Mortierellomycota. In infected soil, the relative abundance of each phylum increased or decreased depending on the pathogen and functional taxonomic classification. Conclusions: Based on our results, we concluded that Fusarium and Rhizopus species cause root rot infection of P. volubilis. In root rot infected P. volubilis, the shift in the rhizosphere fungal community was pathogen-dependent. These findings may serve as a key point for a future study on the biocontrol of root rot of P. volubilis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fusarium%20spp." title="fusarium spp.">fusarium spp.</a>, <a href="https://publications.waset.org/abstracts/search?q=plukenetia%20volubilis%20l." title=" plukenetia volubilis l."> plukenetia volubilis l.</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizopus%20spp." title=" rhizopus spp."> rhizopus spp.</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizosphere%20fungal%20community" title=" rhizosphere fungal community"> rhizosphere fungal community</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20rot" title=" root rot"> root rot</a> </p> <a href="https://publications.waset.org/abstracts/187906/shift-in-the-rhizosphere-soil-fungal-community-associated-with-root-rot-infection-of-plukenetia-volubilis-linneo-caused-by-fusarium-and-rhizopus-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187906.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">43</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">2027</span> Contemporary Terrorism: Root Causes and Misconceptions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Slunecko%20Karat">Thomas Slunecko Karat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The years since 9/11 2001 have given us a plethora of research papers with the word ‘terrorism’ in the title. Yet only a small subset of these papers has produced new data, which explains why more than 20 years of research since 9/11 have done little to increase our understanding of the mechanisms that lead to terrorism. Specifically, terrorism scholars are divided by political, temporal, geographical and financial demarcation lines which prevent a clear definition of terrorism. As a consequence, the true root causes of terrorism remain unexamined. Instead, the psychopathological conditions of the individual have been emphasized despite ample empirical evidence pointing in a different direction. This paper examines the underlying reasons and motives that prevent open discourse about the root causes of terrorism and proposes that terrorism is linked to the current international system of resource allocation and systematic violations of human rights. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=terrorism" title="terrorism">terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20causes%20of%20terrorism" title=" root causes of terrorism"> root causes of terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention%20of%20terrorism" title=" prevention of terrorism"> prevention of terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights%20violations" title=" human rights violations"> human rights violations</a> </p> <a href="https://publications.waset.org/abstracts/165340/contemporary-terrorism-root-causes-and-misconceptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165340.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">92</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">2026</span> Crossing Borders: In Research and Business Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edith%20Podhovnik">Edith Podhovnik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cultures play a role in business communication and in research.

Different irrigant activation systems have been recently used, and one of these devices is the Eddy which helps in removal of smear layer and improves the intimate contact between the filling material and the root canal wall. Aim: To evaluate the efficacy of Eddy in cleanliness of the root canal during pulpectomy of primary teeth. Materials and methods: 45 freshly extracted primary anterior teeth were divided into 3 equal groups, in the 1st group sodium hypochlorite only was used during pulpectomy, in the 2nd group irrigation using sodium hypochlorite with file agitation was performed and in the 3rd group sodium hypochlorite was used with Eddy for irrigant activation. All samples were sectioned longitudinally and scanned using scanning electron microscope to evaluate the cleanliness of the root canals. Results: It was found that Eddy showed high efficacy in removal of smear layer during pulpectomy of primary teeth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eddy" title="Eddy">Eddy</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigant%20activation" title=" irrigant activation"> irrigant activation</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation" title=" irrigation"> irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=pulpectomy" title=" pulpectomy"> pulpectomy</a> </p> <a href="https://publications.waset.org/abstracts/131150/effect-of-eddy-irrigant-activation-on-cleanliness-of-the-root-canal-wall-during-pulpectomy-of-primary-teeth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131150.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">152</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">2024</span> Anatomical and Histological Characters of Cymbopogon nardus Roots and Its Mutagenic Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pravaree%20Phuneerub">Pravaree Phuneerub</a>, <a href="https://publications.waset.org/abstracts/search?q=Chanida%20Palanuvej"> Chanida Palanuvej</a>, <a href="https://publications.waset.org/abstracts/search?q=Nijsiri%20Ruangrungsi"> Nijsiri Ruangrungsi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cymbopogon nardus Rendel (Family Gramineae) is commonly known as citronella grass. The dried root of C. nardus is used for antipyretic, anti-inflammation, anti-analgesic and anticancer in traditional Thai medicine. Transverse sectional and pulverized C. nardus root were illustrated. The volatile oil was extracted from oil gland by hydrodistillation and analysed by GC/MS. Cymbopogon nardus root was exhaustively extracted by continuously maceration in ethanol and water respectively. The mutagenic and antimutagenic properties of the ethanol extract and fractionated water extract of C. nardus root were evaluated by Ames assay using the S. typhimurium strains TA98 and TA100 as the models. The result indicated that the anatomical character of root transverse section displayed epidermis, parenchyma, oil gland, phloem, xylem vessel, endodermis and pith. Histological characters of root powder showed parenchyma containing oleoresin, parenchyma in longitudinal view, reticulate vessel, annular vessel, starch granules and fragment of fiber. The root volatile oil was rich in sesquiterpenes dominated by elemol (22.87%) and alpha-eudesmol (16.09%). For mutagenic activity, the both extracts of C. nardus were no mutagenic toward S. typhimurium strains TA98 and TA100. Furthermore, the ethanol extract and fractionated water extract of C. nardus root demonstrated strong antimutagenic effect against of nitrite treated 1-aminopyrene to S. typhimurium strains TA98 and TA100. This present investigation suggested that the dried root extract of C. nardus can be further developed as promising antimutagenic agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cymbopogon%20nardus" title="Cymbopogon nardus">Cymbopogon nardus</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20oil%20analysis" title=" volatile oil analysis"> volatile oil analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=mutagenic" title=" mutagenic"> mutagenic</a>, <a href="https://publications.waset.org/abstracts/search?q=antimutagenic%20effect" title=" antimutagenic effect"> antimutagenic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Ames%20Salmonella%20assay" title=" Ames Salmonella assay"> Ames Salmonella assay</a> </p> <a href="https://publications.waset.org/abstracts/19042/anatomical-and-histological-characters-of-cymbopogon-nardus-roots-and-its-mutagenic-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19042.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">348</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">2023</span> Salicylic Acid Signalling in Relation to Root Colonization in Rice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seema%20Garcha">Seema Garcha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheetal%20Chopra"> Sheetal Chopra</a>, <a href="https://publications.waset.org/abstracts/search?q=Navraj%20Sarao"> Navraj Sarao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant hormones play a role in internal colonization by beneficial microbes and also systemic acquired resistance. They define qualitative and quantitative nature of root microbiome and also influence dynamics of root rhizospheric soil. The present study is an attempt to relate salicylic acid (signal molecule) content and qualitative nature of root endophytes at various stages in the growth of rice varieties of commercial value- Parmal 121 and Basmati 1121. Root seedlings of these varieties were raised using tissue culture techniques and then they were transplanted in the fields. Cultivation was done using conventional methods in agriculture. Field soil contained 0.39% N, 75.12 Kg/hectare of phosphorus and 163.0 Kg/hectare of potassium. Microfloral profiling of the root tissue was done using the selective microbiological medium. The salicylic acid content was estimated using HPLC-Agilent 1100 HPLC Series. Salicylic acid level of Basmati 1121 remained relatively low at the time of transplant and 90 days after transplant. It increased marginally at 60 days. A similar trend was observed with Parmal 121 as well. However, Parmal variety recorded 0.935 ug/g of salicylic acid at 60 days after transplant. Salicylic acid content decreased after 90 days as both the rice varieties remained disease free. The endophytic root microflora was established by 60 days after transplant in both the varieties after which their population became constant. Rhizobium spp dominated over Azotobacter spp. Genetic profiling of endophytes for nitrogen-fixing ability is underway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plant-microbe%20interaction" title="plant-microbe interaction">plant-microbe interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20microbiome" title=" root microbiome"> root microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=salicylic%20acid" title=" salicylic acid"> salicylic acid</a> </p> <a href="https://publications.waset.org/abstracts/84755/salicylic-acid-signalling-in-relation-to-root-colonization-in-rice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84755.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">202</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">2022</span> An Innovative Poly System Theory for the Go-Out of Chinese Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianhua%20Wang">Jianhua Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhou"> Ying Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Guo"> Han Guo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Translation underwent culture turn for more than half a century, which brought translation and its studies beyond intra-texts. Different cultures in recent years have developed towards a translation turn, which made a great contribution to relocate national or local cultures being localized to become regional or global cultures. As China grows quickly economically integrating into the world, it becomes urgent to relate China’s story and disseminate the Chinese culture. Due to the weaknesses and drawbacks of different existing cultural translation theories for Chinese culture to go out, a new perspective on translation turn for the go-out of Chinese culture should be drawn to spread better and disseminate Chinese culture to other countries. Based on the existing cultural translation theories, the equivalence of ideology, style of the translator and agency of the support are proposed to draw a new perspective: an innovative poly-system theory for Chinese culture translation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20translation%20theory" title="cultural translation theory">cultural translation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20culture" title=" Chinese culture"> Chinese culture</a>, <a href="https://publications.waset.org/abstracts/search?q=innovative%20poly%20system" title=" innovative poly system"> innovative poly system</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20cultures" title=" global cultures"> global cultures</a> </p> <a href="https://publications.waset.org/abstracts/57358/an-innovative-poly-system-theory-for-the-go-out-of-chinese-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57358.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">453</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">2021</span> Plant Cell Culture to Produce Valuable Natural Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jehad%20Dumireih">Jehad Dumireih</a>, <a href="https://publications.waset.org/abstracts/search?q=Malak%20Dmirieh"> Malak Dmirieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Wink"> Michael Wink</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work is aimed to use plant cell suspension cultures of Crataegus monogyna for biosynthesis of valuable natural products by using quercetin as an inexpensive precursor. Suspension cell cultures of C. monogyna were established by using Murashige and Skoog medium (MS) supplemented with 1 mg/L 2,4-dichlorophenoxyacetic acid and 1 mg/L kinetin. Cells were harvested from the cultures and extracted by using methanol and ethyl acetate; then the extracts were used for the identification of isoquercetin by HPLC and by mass spectrometry. The incubation of the cells with 0.24 mM quercetin for one week resulted in an 16 fold increase of isoquercetin biosynthesis; the growth rate of the cells increased by 20%. Moreover, the biosynthesis of isoquercetin was enhanced by 40% when we divided the added quercetin into three portions each one with concentration 0.12 mM supplied at 3 days intervals. In addition, we didn’t find any positive effects of adding different concentrations the precursors phenylalanine (0.2 mM) and galactose to the cell cultures. In conclusion, the efficiency of the biotransformation of quercetin into isoquercetin depended on the concentration quercetin, its incubation time and the way of its administration. The results of the present work suggest that the biotechnological methods such as cell suspension cultures could be successfully used to obtain highly valuable natural product starting from inexpensive compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosynthesis" title="biosynthesis">biosynthesis</a>, <a
