From the fragrant herbs and spices used in cooking to the aromatic incense burned in temples and homes, aromatic plants play multifaceted roles in enhancing well-being and fostering spiritual connections. These plants are valued not only for their pleasant aromas but also for their medicinal properties and symbolic meanings. This article aims to summarize the role of aromatic plants in Indonesian traditional culture, medicine, spirituality, and how it shifted to a modern version of aromatherapy. Traditional Indonesian medicine, known as Jamu, relies heavily on aromatic plants for their therapeutic benefits. Herbalists and traditional healers use a wide array of aromatic herbs, roots, barks, and resins to treat various ailments, ranging from digestive disorders and respiratory infections to skin conditions and reproductive issues. In conclusion, aromatic plants represent a cultural treasure with multifaceted uses and significance deeply rooted in Indonesia’s tradition. From their medicinal properties to their spiritual symbolism, these plants embody the interconnection of culture, nature, and well-being. Further research and collaboration are needed to document and preserve traditional knowledge surrounding Indonesian aromatic plants and ensure their continued recognition and sustainable utilization in the face of modernization and environmental challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20plants" title="aromatic plants">aromatic plants</a>, <a href="https://publications.waset.org/abstracts/search?q=indonesia" title=" indonesia"> indonesia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamu" title=" Jamu"> Jamu</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20medicine" title=" traditional medicine"> traditional medicine</a> </p> <a href="https://publications.waset.org/abstracts/184586/exploring-the-traditional-uses-of-aromatic-plants-in-indonesian-culture-medicine-and-spirituality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184586.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">356</span> Optimal Production Planning in Aromatic Coconuts Supply Chain Based on Mixed-Integer Linear Programming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaimongkol%20Limpianchob">Chaimongkol Limpianchob</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work addresses the problem of production planning that arises in the production of aromatic coconuts from Samudsakhorn province in Thailand. The planning involves the forwarding of aromatic coconuts from the harvest areas to the factory, which is classified into two groups; self-owned areas and contracted areas, the decisions of aromatic coconuts flow in the plant, and addressing a question of which warehouse will be in use. The problem is formulated as a mixed-integer linear programming model within supply chain management framework. The objective function seeks to minimize the total cost including the harvesting, labor and inventory costs. Constraints on the system include the production activities in the company and demand requirements. Numerical results are presented to demonstrate the feasibility of coconuts supply chain model compared with base case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20coconut" title="aromatic coconut">aromatic coconut</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed-integer%20linear%20programming" title=" mixed-integer linear programming"> mixed-integer linear programming</a> </p> <a href="https://publications.waset.org/abstracts/6619/optimal-production-planning-in-aromatic-coconuts-supply-chain-based-on-mixed-integer-linear-programming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6619.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">460</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">355</span> Preparation and Characterization of Copper-Nanoparticle on Extracted Carrageenan and Its Catalytic Activity for Reducing Aromatic Nitro Group</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vida%20Jodaeian">Vida Jodaeian</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Sani"> Behzad Sani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Copper nanoparticles were successfully synthesized and characterized on green-extracted Carrageenan from seaweed by precipitation method without using any supporter and template with precipitation method.

Antibiotics have been used as growth factors in animal feeds for many years. They prohibited; because of increased residue problem and increased resistance to antibiotics in bacteria due to prolonged use. Aromatic plants and extracts have attracted the attention of scientists nowadays due to positive reasons such as confidence of the community to the products those are coming from nature, desire to consume, and no residue problems. Plant extracts are obtained from aromatic plants, and they come forward with antifungal, antibacterial, antiviral, antioxidant and antilipidemic properties. It has been stated that intestinal histomorphology and microbiosis are positively affected by the use of plant extract in feeds. In the present day, aromatic plants and extracts are a remarkable research field with intriguing unknowns in the field of animal nutrition, and they continue to exist in the journal in vitro and in vivo studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20plant" title="aromatic plant">aromatic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=broilers" title=" broilers"> broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=extract%20mechanism%20of%20action" title=" extract mechanism of action"> extract mechanism of action</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20health" title=" intestinal health"> intestinal health</a> </p> <a href="https://publications.waset.org/abstracts/85014/effect-mechanisms-of-aromatic-plants-effects-on-intestinal-health-and-broiler-feeding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85014.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">353</span> Study on the Treatment of Waste Water Containing Nitrogen Heterocyclic Aromatic Hydrocarbons by Phenol-Induced Microbial Communities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhichao%20Li">Zhichao Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This project has treated the waste-water that contains the nitrogen heterocyclic aromatic hydrocarbons, by using the phenol-induced microbial communities. The treatment of nitrogen heterocyclic aromatic hydrocarbons is a difficult problem for coking waste-water treatment. Pyridine, quinoline and indole are three kinds of most common nitrogen heterocyclic compounds in the f, and treating these refractory organics biologically has always been a research focus. The phenol-degrading bacteria can be used in the enhanced biological treatment effectively, and has a good treatment effect. Therefore, using the phenol-induced microbial communities to treat the coking waste-water can remove multiple pollutants concurrently, and improve the treating efficiency of coking waste-water.

Land farming is one of the methods that remove pollutants from the soil by native microorganisms. It seems that this technology is cost-effective, environmentally friendly and causes less debris problem to be disposed. This study aimed to refine the polycyclic aromatic hydrocarbons from oil-contaminated soil using the land farming method. In addition to examine the concentration of polycyclic aromatic hydrocarbons by GC-FID, some characteristics such as soil microbial respiration and dehydrogenase, peroxidase, urease, acid and alkaline phosphatase enzyme concentration were also measured. The results showed that after land farming process the concentrations of some polycyclic aromatic hydrocarbons dropped to 50 percent. The results showed that the enzyme concentration is reduced by reducing the concentration of hydrocarbons and microbial respiration. These results emphasize the process of land farming for removal of polycyclic aromatic hydrocarbons from soil by indigenous microorganisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20contamination" title="soil contamination">soil contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography" title=" gas chromatography"> gas chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=native%20microorganisms" title=" native microorganisms"> native microorganisms</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20enzymes" title=" soil enzymes"> soil enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20respiration" title=" microbial respiration"> microbial respiration</a>, <a href="https://publications.waset.org/abstracts/search?q=carcinogen" title=" carcinogen"> carcinogen</a> </p> <a href="https://publications.waset.org/abstracts/5748/bioremediation-of-pahs-contaminated-soil-using-land-treatment-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5748.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">385</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">351</span> Study of Polycyclic Aromatic Hydrocarbons Biodegradation by Bacterial Isolated from Contaminated Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Abdessemed">Z.

The variety and the performance of these enzymes allow the initiation of the biodegradation of any PAH through many different metabolic pathways.

In the present study, the efficiency of aluminium based electrocoagulation on the removal of prominent aromatic groups such as phenol, hydrophobic auxochromes, and carboxyl groups from NOM enriched synthetic water has been evaluated using various spectral indices. The effect of electrocoagulation on turbidity has also been discussed. The variation in coagulation performance as a function of pH has been studied. Our result suggests that electrocoagulation can be considered as appropriate remediation approach to reduce trihalomethanes formation in water. It has effectively reduced hydrophobic fractions from NOM enriched low turbid water. The charge neutralization and enmeshment of dispersed colloidal particles inside metallic hydroxides is the possible mechanistic approach in electrocoagulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20fractions" title="aromatic fractions">aromatic fractions</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title=" electrocoagulation"> electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20organic%20matter" title=" natural organic matter"> natural organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20indices" title=" spectral indices"> spectral indices</a> </p> <a href="https://publications.waset.org/abstracts/71237/removal-of-aromatic-fractions-of-natural-organic-matter-from-synthetic-water-using-aluminium-based-electrocoagulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71237.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">277</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">349</span> Degradation of Polycyclic Aromatic Hydrocarbons-Contaminated Soil by Proxy-Acid Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Samsami">Reza Samsami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study was to degradation of polycyclic aromatic hydrocarbons (PAHs) by proxy-acid method.

Frequently with phenol, furfural, NMP(N-methyl pyrrolidone). The solvent power and selectivity can be further increased by using surfactant as additive which facilitate phase separation and to increase raffinate yield. The aromatics in lube oil were extracted at different temperatures (ranging from 333.15 to 343.15K) and different concentration of surfactant (ranging from 0.01 to 0.1% wt).The extraction temperature and the amount of sulfate lauryl éther de sodium In phenoll were investigated systematically in order to determine their optimum values. The amounts of aromatic, paraffinic and naphthenic compounds were determined using ASTM standards by measuring refractive index (RI), viscosity, molecular weight and sulfur content. It was found that using 0,01%wt. surfactant at 343.15K yields the optimum extraction conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricating%20oil" title=" lubricating oil"> lubricating oil</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatics" title=" aromatics"> aromatics</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbons" title=" hydrocarbons"> hydrocarbons</a> </p> <a href="https://publications.waset.org/abstracts/19800/extraction-of-aromatic-hydrocarbons-from-lub-oil-using-sursurfactant-as-additive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19800.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">521</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">347</span> Medicinal and Aromatic Plants of Ardanuç (Artvi̇n, Türki̇ye)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zg%C3%BCr%20Emi%CC%87na%C4%9Fao%C4%9Flu">Özgür Emi̇nağaoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayal%20Akyildirim%20Be%C4%9Fen"> Hayal Akyildirim Beğen</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eevval%20Sali%CC%87o%C4%9Flu"> Şevval Sali̇oğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Y%C3%BCksel"> Emrah Yüksel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was carried out in order to determine the scientific name, common name, local names, location, botanical characteristics, used parts, intended use, local usage patterns, usage in the literature of plant species used for medicinal and aromatic purposes in Ardanuç (Artvin, Türkiye) between 2020-2023 years.

Based on that, the biological input, maturity of crude oils and sedimentary environment of the corresponding source rocks were determined and the origin types of crude oils were divided. The results show that there are three types of crude oils in the study area including Type I, Type II and Type III oils. The crude oils from the 1st member of the Neogene Shawan Formation are the Type I oils; the crude oils from the 2nd member of the Neogene Shawan Formation are the Type II oils; the crude oils from the Cretaceous Qingshuihe and Jurassic Badaowan Formations are the Type III oils. For the Type I oils, they show a single model in the late retention time of the chromatogram of total aromatic hydrocarbons. The content of triaromatic steroid series is high, and the content of dibenzofuran is low. Maturity parameters related to alkyl naphthalene, methylphenanthrene and alkyl dibenzothiophene all indicate low maturity for the Type I oils. For the Type II oils, they have also a single model in the early retention time of the chromatogram of total aromatic hydrocarbons. The content of naphthalene and phenanthrene series is high, and the content of dibenzofuran is medium. The content of polycyclic aromatic hydrocarbon representing the terrestrial organic matter is high. The aromatic maturity parameters indicate high maturity for the Type II oils. For the Type III oils, they have a bi-model in the chromatogram of total aromatic hydrocarbons. The contents of naphthalene series, phenanthrene series, and dibenzofuran series are high. The aromatic maturity parameters indicate medium maturity for the Type III oils. The correlation results of triaromatic steroid series fingerprint show that the Type I and Type III oils have similar source and are both from the Permian Wuerhe source rocks. Because of the strong biodegradation and mixing from other source, the Type I oils are very different from the Type III oils in aromatic hydrocarbon characteristics. The Type II oils have the typical characteristics of terrestrial organic matter input under oxidative environment, and are the coal oil mainly generated by the mature Jurassic coal measure source rocks. However, the overprinting effect from the low maturity Cretaceous source rocks changed the original distribution characteristics of aromatic hydrocarbons to some degree. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20source" title="oil source">oil source</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemistry" title=" geochemistry"> geochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatic%20hydrocarbons" title=" aromatic hydrocarbons"> aromatic hydrocarbons</a>, <a href="https://publications.waset.org/abstracts/search?q=crude%20oils" title=" crude oils"> crude oils</a>, <a href="https://publications.waset.org/abstracts/search?q=chepaizi%20area" title=" chepaizi area"> chepaizi area</a>, <a href="https://publications.waset.org/abstracts/search?q=Junggar%20Basin" title=" Junggar Basin"> Junggar Basin</a> </p> <a href="https://publications.waset.org/abstracts/63701/geochemical-characteristics-of-aromatic-hydrocarbons-in-the-crude-oils-from-the-chepaizi-area-junggar-basin-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63701.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">353</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">343</span> Bioaccumulation of Polycyclic Aromatic Hydrocarbons in Padina boryana Alga Collected from a Contaminated Site at the Red Sea, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huda%20Qari">Huda Qari</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20A.%20Hassan"> I.

It is applied in various fields of study self-driving cars, video surveillance, agriculture, Quality control, Health care, construction, military, and everyday life. Aromatic and medicinal plants are botanical raw materials used in cosmetics, medicines, health foods, and other natural health products for therapeutic and Aromatic culinary purposes. Herbal industries depend on these special plants. These plants and their products not only serve as a valuable source of income for farmers and entrepreneurs, and going to export not only industrial raw materials but also valuable foreign exchange. There is a lack of technologies for the classification and identification of Aromatic and medicinal plants in Ethiopia. The manual identification system of plants is a tedious, time-consuming, labor, and lengthy process. For farmers, industry personnel, academics, and pharmacists, it is still difficult to identify parts and usage of plants before ingredient extraction. In order to solve this problem, the researcher uses a deep learning approach for the efficient identification of aromatic and medicinal plants by using a convolutional neural network. The objective of the proposed study is to identify the aromatic and medicinal plant Parts and usages using computer vision technology. Therefore, this research initiated a model for the automatic classification of aromatic and medicinal plants by exploring computer vision technology. Morphological characteristics are still the most important tools for the identification of plants. Leaves are the most widely used parts of plants besides the root, flower and fruit, latex, and barks. The study was conducted on aromatic and medicinal plants available in the Ethiopian Institute of Agricultural Research center. An experimental research design is proposed for this study. This is conducted in Convolutional neural networks and Transfer learning. The Researcher employs sigmoid Activation as the last layer and Rectifier liner unit in the hidden layers. Finally, the researcher got a classification accuracy of 66.4 in convolutional neural networks and 67.3 in mobile networks, and 64 in the Visual Geometry Group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20and%20medicinal%20plants" title="aromatic and medicinal plants">aromatic and medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20convolutional%20neural%20network" title=" deep convolutional neural network"> deep convolutional neural network</a> </p> <a href="https://publications.waset.org/abstracts/149907/aromatic-medicinal-plant-classification-using-deep-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149907.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">438</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">341</span> Study of Some Aromatic Thiourea Derivatives as Lube Oil Antioxidant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasha%20S.%20Kamal">Rasha S.

Freshly harvested aromatic rice exhibits strong aromatic scent but decreases with time and conditions during storage. Of the many volatile compounds in aromatic rice, 2-acetyl-1-pyrroline (2AP) is a major compound that gives rice its popcorn-like aroma. The diffusion mechanism of 2AP in rice was investigated. Semi-empirical models explaining 2AP diffusion as affected by temperature and duration were developed. Storage time and temperature affected 2AP loss via diffusion. The amount of 2AP in rice decreased with time. Free 2AP, being volatile, is lost due to diffusion. Storage experiment indicated rapid 2AP loss during the first five weeks and subsequently leveled off afterwards; attaining level of starch bound 2AP. Decline of 2AP during storage followed exponential equation and exhibited four stages; i.e. the initial, second, third and final stage. Free 2AP is easily lost while bound 2AP is left, only to be released upon exposure to high temperature such as cooking. Both free and bound 2AP is found in endosperm while free 2AP is in the bran. Around 63–67% of total 2AP was lost in brown and milled rice of MS 6 paddy kept at ambient. Samples stored at higher temperature (27°C) recorded higher 2AP loss than those kept at lower temperature (15°C). The study should be able to guide processors in understanding and controlling parameters in storage to produce high quality rice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2-acetyl-1-pyrroline" title="2-acetyl-1-pyrroline">2-acetyl-1-pyrroline</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatic%20rice" title=" aromatic rice"> aromatic rice</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20mechanism" title=" diffusion mechanism"> diffusion mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage "> storage </a> </p> <a href="https://publications.waset.org/abstracts/14755/diffusion-mechanism-of-aroma-compound-2-acetyl-1-pyrroline-in-rice-during-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14755.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">338</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">339</span> Carcinogenic Polycyclic Aromatic Hydrocarbons in Urban Air Particulate Matter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Szab%C3%B3%20Nagy">A.

A high volume sampler was used for the collection of ambient aerosol particles, and the associated cPAH compounds (benzo[a]pyrene (BaP), benzo[a]anthracene, benzofluoranthene isomers, indeno[123-cd]pyrene and dibenzo[ah]anthracene) were analyzed by a gas chromatographic method. Higher mean concentrations of total cPAHs were detected in samples collected in winter (9.62 ng/m<sup>3</sup>) and autumn (2.69 ng/m<sup>3</sup>) compared to spring (1.05 ng/m<sup>3</sup>) and summer (0.21 ng/m<sup>3</sup>). The calculated <em>BaP</em> <em>toxic equivalent concentrations</em> have also reflected that the local population appears to be exposed to significantly higher cancer risk in the heating seasons. Moreover, the concentration levels of cPAHs determined in this study were compared to other Hungarian urban sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air" title="air">air</a>, <a href="https://publications.waset.org/abstracts/search?q=carcinogenic" title=" carcinogenic"> carcinogenic</a>, <a href="https://publications.waset.org/abstracts/search?q=polycyclic%20aromatic%20hydrocarbons%20%28PAH%29" title=" polycyclic aromatic hydrocarbons (PAH)"> polycyclic aromatic hydrocarbons (PAH)</a>, <a href="https://publications.waset.org/abstracts/search?q=PM10" title=" PM10"> PM10</a> </p> <a href="https://publications.waset.org/abstracts/67011/carcinogenic-polycyclic-aromatic-hydrocarbons-in-urban-air-particulate-matter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67011.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">271</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">338</span> Antioxidant Potential of Methanolic Extracts of Four Indian Aromatic Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harleen%20Kaur">Harleen Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Richa"> Richa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plants produce a large variety of secondary metabolites. Phenolics are the compounds that contain hydroxyl functional group on an aromatic ring. These are chemically heterogeneous compounds. Some are soluble only in organic solvents, some are water soluble and others are large insoluble polymers. Flavonoids are one of the largest classes of plant phenolics. The carbon skeleton of a flavonoid contains 15 carbons arranged in two aromatic rings connected by a three carbon ridge. Both phenolics and flavonoids are good natural antioxidants. Four Indian aromatic plants were selected for the study i.e, Achillea species, Jasminum primulinum, Leucas cephalotes and Leonotis nepetaefolia. All the plant species were collected from Chail region of Himachal Pradesh, India. The identifying features and anatomical studies were done of the part containing the essential oils. Phenolic cotent was estimated by Folin Ciocalteu’s method and flavonoids content by aluminium chloride method. Antioxidant property was checked by using DPPH method. Maximum antioxidant potential was found in Achillea species, followed by Leonotis nepetaefolia, Jaminum primulinum and Leucas cephalotes. Phenolics and flavonoids are important compounds that serve as defences against herbivores and pathogens. Others function in attracting pollinators and absorbing harmful radiations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title="antioxidants">antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH" title=" DPPH"> DPPH</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolics" title=" phenolics"> phenolics</a> </p> <a href="https://publications.waset.org/abstracts/37377/antioxidant-potential-of-methanolic-extracts-of-four-indian-aromatic-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37377.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">347</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">337</span> Seasonal Variation of Polycyclic Aromatic Hydrocarbons Associated with PM10 in Győr, Hungary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Szab%C3%B3%20Nagy">Andrea Szabó Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%A1nos%20Szab%C3%B3"> János Szabó</a>, <a href="https://publications.waset.org/abstracts/search?q=Zs%C3%B3fia%20Csan%C3%A1di"> Zsófia Csanádi</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%B3zsef%20Erd%C5%91s"> József Erdős</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study was to assess the seasonal variation of atmospheric polycyclic aromatic hydrocarbon (PAH) concentrations associated with PM10 in an urban site of Győr, Hungary. A total of 112 PM10 aerosol samples were collected in the years of 2012 and 2013 and analyzed for PAHs by gas chromatography method. The total PAH concentrations (sum of the concentrations of 19 individual PAH compounds) ranged from 0.19 to 70.16 ng/m3 with the mean value of 12.29 ng/m3. Higher concentrations of both total PAHs and benzo[a]pyrene (BaP) were detected in samples collected in the heating seasons. Using BaP-equivalent potency index on the carcinogenic PAH concentration data, the local population appears to be exposed to significantly higher cancer risk in the heating seasons.

As the system does not permit the use of synthetic fertilizers the use of nutrient rich organic manures is extremely important. CSIR-CIMAP has developed a complete recycling package for managing distillation and agro-waste of medicinal and aromatic plants for production of superior quality vermicompost involving microbes capable of producing high amounts of humic acid. The major benefits being faster composting period and nutrient rich vermicompost; a nutrient advantage of about 100-150% over the most commonly used organic manure (FYM). At CSIR-CIMAP, strains of microbial inoculants with multiple activities especially strains useful both as biofertilizers and biofungicide and consortia of microbes possessing diverse functional activities have been developed. CSIR-CIMAP has also initiated a program where a large number of accessions are being screened for identifying organic proficient genotypes in mints, ashwagandha, geranium and safed musli. Some of the natural plant growth promoters like calliterpenones from the plant Callicarpa macrophylla has been tested successfully for induction of rooting in stem cuttings and improving growth and yield of various crops. Some of the microbes especially the endophytes have even been identified improving the active constituents of medicinal and aromatic plants.

It is used in a wide range of fields of study, including self-driving cars, video surveillance, medical diagnosis, manufacturing, law, agriculture, quality control, health care, facial recognition, and military applications. Aromatic medicinal plants are botanical raw materials used in cosmetics, medicines, health foods, essential oils, decoration, cleaning, and other natural health products for therapeutic and Aromatic culinary purposes. These plants and their products not only serve as a valuable source of income for farmers and entrepreneurs but also going to export for valuable foreign currency exchange. In Ethiopia, there is a lack of technologies for the classification and identification of Aromatic medicinal plant parts and disease type cured by aromatic medicinal plants. Farmers, industry personnel, academicians, and pharmacists find it difficult to identify plant parts and disease types cured by plants before ingredient extraction in the laboratory. Manual plant identification is a time-consuming, labor-intensive, and lengthy process. To alleviate these challenges, few studies have been conducted in the area to address these issues. One way to overcome these problems is to develop a deep learning model for efficient identification of Aromatic medicinal plant parts with their corresponding disease type. The objective of the proposed study is to identify the aromatic medicinal plant parts and their disease type classification using computer vision technology. Therefore, this research initiated a model for the classification of aromatic medicinal plant parts and their disease type by exploring computer vision technology. Morphological characteristics are still the most important tools for the identification of plants. Leaves are the most widely used parts of plants besides roots, flowers, fruits, and latex. For this study, the researcher used RGB leaf images with a size of 128x128 x3. In this study, the researchers trained five cutting-edge models: convolutional neural network, Inception V3, Residual Neural Network, Mobile Network, and Visual Geometry Group. Those models were chosen after a comprehensive review of the best-performing models. The 80/20 percentage split is used to evaluate the model, and classification metrics are used to compare models. The pre-trained Inception V3 model outperforms well, with training and validation accuracy of 99.8% and 98.7%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20medicinal%20plant" title="aromatic medicinal plant">aromatic medicinal plant</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title=" convolutional neural network"> convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20classification" title=" plant classification"> plant classification</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20neural%20network" title=" residual neural network"> residual neural network</a> </p> <a href="https://publications.waset.org/abstracts/175749/multi-labeled-aromatic-medicinal-plant-image-classification-using-deep-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175749.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">333</span> Spent Paint Solvent Recoveries by Ionic Liquids: Potential for Industrial Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mbongeni%20Mabaso">Mbongeni Mabaso</a>, <a href="https://publications.waset.org/abstracts/search?q=Kandasamy%20Moodley"> Kandasamy Moodley</a>, <a href="https://publications.waset.org/abstracts/search?q=Gan%20Redhi"> Gan Redhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recovery of industrially valuable organic solvents from liquid waste, generated in chemical processes, is economically crucial to countries which need to import organic solvents. In view of this, the main objective of this study was to determine the ability of selected ionic liquids, namely, 1-ethyl-3-methylimidazolium ethylsulphate, [EMIM] [ESO4] and 1-ethyl-3-methylpyridinium ethylsulphate, [EMpy][ESO4] to recover aromatic components from spent paint solvents. Preliminary studies done on the liquid waste, received from a paint manufacturing company, showed that the aromatic components were present in the range 6 - 21 % by volume. The separation of the aromatic components was performed with the ionic liquids listed above. The phases, resulting from the separation of the mixtures, were analysed with a Gas Chromatograph (GC) coupled to a FID detector. Chromatograms illustrate that the chosen ZB-Wax-Plus column gave excellent separation of all components of interest from the mixtures, including the isomers of xylene. The concentrations of aromatics recovered from the spent solvents were found to be the % ranges 13-33 and 23-49 respectively for imidazolium and pyridinium ionic liquids. These results also show that there is a significant correlation between π-character of ionic liquids and the level of extraction. It is therefore concluded that ionic liquids have the potential for macro-scale recovery of re-useable solvents present in liquid waste emanating from paint manufacture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthesis" title="synthesis">synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquid" title=" ionic liquid"> ionic liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=imidazolium" title=" imidazolium"> imidazolium</a>, <a href="https://publications.waset.org/abstracts/search?q=pyridinium" title=" pyridinium"> pyridinium</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatic%20solvents" title=" aromatic solvents"> aromatic solvents</a>, <a href="https://publications.waset.org/abstracts/search?q=spent%20paint%20organic%20solvents" title=" spent paint organic solvents"> spent paint organic solvents</a> </p> <a href="https://publications.waset.org/abstracts/39343/spent-paint-solvent-recoveries-by-ionic-liquids-potential-for-industrial-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39343.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">337</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">332</span> Medicinal and Aromatic Plants of Borcka (Artvin)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zg%C3%BCr%20Emi%CC%87na%C4%9Fao%C4%9Flu">Özgür Emi̇nağaoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayal%20Akyildirim%20Be%C4%9Fen"> Hayal Akyildirim Beğen</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eevval%20Sali%CC%87o%C4%9Flu"> Şevval Sali̇oğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the plant used for purification and aromatic purposes by the public in Adagül, Akpınar, Alaca, Ambarlı, Arkaköy, Avcılar, Balcı, Civan, Demirciler, Düzköy, İbrikli, Kale, Kaynarca and Taraklı villages in Borcka (Artvin) district between 2020-2022.

Kinetic analysis of the flame by calculating the maximum rates for each elementary reaction, allowed us to identify key reactions pathways of consumption and formation of main precursors of soot. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benzene" title="benzene">benzene</a>, <a href="https://publications.waset.org/abstracts/search?q=PAH" title=" PAH"> PAH</a>, <a href="https://publications.waset.org/abstracts/search?q=acetylene" title=" acetylene"> acetylene</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=flame" title=" flame"> flame</a>, <a href="https://publications.waset.org/abstracts/search?q=soot" title=" soot"> soot</a> </p> <a href="https://publications.waset.org/abstracts/40140/soot-formation-in-the-field-of-combustion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40140.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">335</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">330</span> α-Amylase Inhibitory Activity of Some Tunisian Aromatic and Medicinal Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdi%20Belfeki">Hamdi Belfeki</a>, <a href="https://publications.waset.org/abstracts/search?q=Belgacem%20Chandoul"> Belgacem Chandoul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mnasser%20Hassouna"> Mnasser Hassouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Mondher%20Mejri"> Mondher Mejri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aqueous and ethanolic extracts of eight Tunisian aromatic and medicinal plants (TAMP) were characterized by studying their composition in polyphenols and also their antiradical and antioxidant capacities. In absence and in the presence of the various extracts, α-amylase from Bacillus subtlis activity, was measured in order to detect a potential inhibition. The total contents of polyphenols and flavonoid vary in function of TAMP and the mobile phase used for the extraction (distilled water or ethanol). The ethanolic extracts showed the most significant antiradical and antioxidant activities. Only the extracts from Coriandrum sativum showed a significant inhibiting effect on the α-amylase activity. This inhibiting capacity could be correlated with the chemical profile of the two extracts, due to the fact that they have the greatest amount of total flavonoid. The ethanolic extract has the most important antioxidant and anti-radicalizing activities among the sixteen extracts studied. The inhibition kinetics of the two coriander extracts were evaluated by pre-incubation method, using Lineweaver-Burk’s equation, obtained by linearization of Michaeilis-Menten’s expression. The results showed that both extracts exercised a competitive inhibition mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B1-amylase" title="α-amylase">α-amylase</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatic%20and%20medicinal%20plants" title=" aromatic and medicinal plants"> aromatic and medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibition" title=" inhibition"> inhibition</a> </p> <a href="https://publications.waset.org/abstracts/10661/a-amylase-inhibitory-activity-of-some-tunisian-aromatic-and-medicinal-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10661.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">449</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">329</span> Substitution of Formaldehyde in Phenolic Resins with Innovative and Bio-Based Vanillin Derived Compounds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvain%20Caillol">Sylvain Caillol</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghislain%20David"> Ghislain David</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phenolic resins are industrially used in a wide range of applications from commodity and construction materials to high-technology aerospace industry. They are mainly produced from the reaction between phenolic compounds and formaldehyde. Nevertheless, formaldehyde is a highly volatile and hazardous compound, classified as a Carcinogenic, Mutagenic and Reprotoxic chemical (CMR). Vanillin is a bio-based and non-toxic aromatic aldehyde compound obtained from the abundant lignin resources. Also, its aromaticity is very interesting for the synthesis of phenolic resins with high thermal stability. However, because of the relatively low reactivity of its aldehyde function toward phenolic compounds, it has never been used to synthesize phenolic resins. We developed innovative functionalization reactions and designed new bio-based aromatic aldehyde compounds from vanillin. Those innovative compounds present improved reactivity toward phenolic compounds compared to vanillin. Moreover, they have target structures to synthesize highly cross-linked phenolic resins with high aromatic densities. We have obtained phenolic resins from substituted vanillin, thus without the use of any aldehyde compound classified as CMR. The analytical tests of the cured resins confirmed that those bio-based resins exhibit high levels of performance with high thermal stability and high rigidity properties <p
