The aim of the present study was to assess the anti-inflammatory activities of the essential oil of rose geranium (RGEO). The chemical composition of the RGEO was investigated by gas chromatography. The major components were citronellol (29.13%), geraniol (12.62%), and citronellyl formate (8.06%). In the carrageenan induced paw edema, five different groups were established and RGEO was administered orally in three different doses. RGEO (100 mg/kg) was able to significantly reduce the paw edema with a comparable effect to that observed with diclofenac, the positive control. In addition, RGEO showed a potent anti-inflammatory activity by topical treatment in the method of croton oil-induced ear edema. When the dose was 5 or 10 ml of RGEO per ear, the inflammation was reduced by 73 and 88%, respectively. This is the first report to demonstrate a significant anti-inflammatory activity of Algerian RGEO. In addition, histological analysis confirmed that RGEO inhibited the inflammatory responses in the skin. Our results indicate that RGEO may have significant potential for the development of novel anti-inflammatory drugs with improved safety profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory%20effect" title="anti-inflammatory effect">anti-inflammatory effect</a>, <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title=" carrageenan"> carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=citronellol" title=" citronellol"> citronellol</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20geranium" title=" Rose geranium"> Rose geranium</a> </p> <a href="https://publications.waset.org/abstracts/41605/rose-geranium-essential-oil-as-a-source-of-new-and-safe-anti-inflammatory-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41605.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">341</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">216</span> Phytochemical Screening and Identification of Anti-Biological Activity Properties of Pelargonium graveolens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anupalli%20Roja%20Rani">Anupalli Roja Rani</a>, <a href="https://publications.waset.org/abstracts/search?q=Saraswathi%20Jaggali"> Saraswathi Jaggali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rose-scented geranium (Pelargonium graveolens L’Hér.) is an erect, much-branched shrub. It is indigenous to various parts of southern Africa, and it is often called Geranium. Pelargonium species are widely used by traditional healers in the areas of Southern Africa by Sotho, Xhosa, Khoi-San and Zulus for its curative and palliative effects in the treatment of diarrhea, dysentery, fever, respiratory tract infections, liver complaints, wounds, gastroenteritis, haemorrhage, kidney and bladder disorders. We have used Plant materials for extracting active compounds from analytical grades of solvents methanol, ethyl acetate, chloroform and water by a soxhlet apparatus. The phytochemical screening reveals that extracts of Pelargonium graveolens contains alkaloids, glycosides, steroids, tannins, saponins and phenols in ethyl acetate solvent. The antioxidant activity was determined using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) bleaching method and the total phenolic content in the extracts was determined by the Folin–Ciocalteu method. Due to the presence of different phytochemical compounds in Pelargonium the anti-microbial activity against different micro-organisms like E.coli, Streptococcus, Klebsiella and Bacillus. Fractionation of plant extract was performed by column chromatography and was confirmed with HPLC analysis, NMR and FTIR spectroscopy for the compound identification in different organic solvent extracts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pelargonium%20graveolens%20L%E2%80%99H%C3%A9r" title="Pelargonium graveolens L’Hér">Pelargonium graveolens L’Hér</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH" title=" DPPH"> DPPH</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-organisms" title=" micro-organisms"> micro-organisms</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC%20analysis" title=" HPLC analysis"> HPLC analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=NMR" title=" NMR"> NMR</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR%20spectroscopy" title=" FTIR spectroscopy"> FTIR spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/11915/phytochemical-screening-and-identification-of-anti-biological-activity-properties-of-pelargonium-graveolens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11915.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">500</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">215</span> Empirical Investigation of the Ecoprint Technique and Natural Dyes Using Geranium and Petunia Petals in a Sustainable Way</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Rojo%20Granados">María Rojo Granados</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents an empirical investigation of the performance of pink and purple petunia petals and orange and red geranium petals on a linen fabric using the Eco Print technique.

As a result, consumption and production locations have increasingly become spatially decoupled. This decoupling leads to complex entanglements of systems and sustainability challenges across distances -entanglements which can be conceptualized as telecouplings. Through telecouplings, people and environments across the world have become closely connected, bringing challenges as well as opportunities. Some argue that telecoupling dynamics started taking shape during times of colonization when resources were first traded across the world. An example of such a telecoupling is that of the rose. Every third rose sold in Europe is grown in Kenya and enters the European market through the Dutch flower auction system. Many Kenyan farms are Dutch-owned, closely entangling Kenya and the Netherlands through the trade of roses. Furthermore, the globalization of the flower industry and the resulting shift of production away from the Netherlands and towards Kenya has led to significant changes in the Dutch horticulture sector. However, the sustainability effects of this rose telecoupling is limited neither to the horticulture sector nor to the Netherlands and Kenya. Alongside the flow of roses between these countries come complex financial, knowledge-based, and regulatory flows. The rose telecoupling also creates spillover effects to other countries, such as Ethiopia, and other industries, such as Kenyan tourism. Therefore, telecoupling dynamics create complex entanglements that cut across sectors, environments, communities, and countries, which makes effectively governing and managing telecouplings and their sustainability implications challenging. Indeed, sustainability can no longer be studied in spatial and temporal isolation. This paper aims to map the rose telecoupling’s complex environmental and social interactions to identify points of tension guiding sustainability-targeted interventions. Mapping these interactions will provide a more holistic understanding of the sustainability challenges involved in the Dutch-Kenyan rose trade. This interdisciplinary telecoupling approach reframes and integrates interdisciplinary knowledge about the rose trade between the Netherlands, Kenya, and beyond. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dutch-Kenyan%20rose%20trade" title="Dutch-Kenyan rose trade">Dutch-Kenyan rose trade</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-ecological%20system" title=" socio-ecological system"> socio-ecological system</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=telecoupling" title=" telecoupling"> telecoupling</a> </p> <a href="https://publications.waset.org/abstracts/166521/a-telecoupling-lens-to-study-global-sustainability-entanglements-along-supply-chains-the-case-of-dutch-kenyan-rose-trade" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166521.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">104</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">212</span> Assessing Genetic Variation of Dog Rose (Rosa Canina L.) in Caspian Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aptin%20Rahnavard">Aptin Rahnavard</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghavamaldin%20Asadian"> Ghavamaldin Asadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Pourshamsian"> Khalil Pourshamsian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariamalsadat%20Taghavi"> Mariamalsadat Taghavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dog rose is one of the important rose species in Iran that the distant past had been considered due to nutritional value and medicinal.

The Aboriginals are persistently facing Oppression and Marginalization in their own land owing to Colonial presence. Women in particular are getting most affected. They are facing double burden of patriarchy and their being Native. Tomson Highway, the Cree Canadian playwright has deftly exposed the theme of women violence and empowerment. In his plays (The Rez Sisters and Rose) taken from his Rez Septology, he has depicted Aboriginal women’s predicaments and sufferings. But simultaneously also talks about their empowerment and aggression refuting and fighting back to patriarchy and oppression. The Rez Sisters portrays women with shattering images and as a victim of both the male dominating society and the system. It represents the painful odyssey of the seven women facing several hardships. Rose represents women in entirely different light. They are shown more assertive and empowered raising their voice against the Violence and Discrimination meted out to them. The Aboriginal women in Canada are facing dual burden of Colonialism and Patriarchy which indeed is a Colonial construct. This paper is an attempt to explore the above facets Tomson Highway’s The Rez Sisters and Rose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=violence" title="violence">violence</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a>, <a href="https://publications.waset.org/abstracts/search?q=discrimination" title=" discrimination"> discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=postcolonialism%20feminism" title=" postcolonialism feminism"> postcolonialism feminism</a> </p> <a href="https://publications.waset.org/abstracts/21948/violence-and-aggression-of-women-in-native-canada-a-postcolonial-feminist-study-of-the-rez-sisters-and-rose-by-tomson-highway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21948.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">627</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">210</span> Taxonomic Study and Environmental Ecology of Parrot (Rose Ringed) in City Mirpurkhas, Sindh, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Liaquat%20Ali">Aisha Liaquat Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Sarwar%20Gachal"> Ghulam Sarwar Gachal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Yusuf%20Sheikh"> Muhammad Yusuf Sheikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Parrot rose ringed (Psittaculla krameri) commonly known as Tota, belongs to the order ‘Psittaciformes’ and family ‘Psittacidea’.

The parrot rose-ringed has been categorized the least concern species, the core aim of the present study is to investigate the ecology and taxonomy of parrot (rose-ringed). Sampling was obtained for the taxonomic identification from various adjoining areas in City Mirpurkhas by non-random method, which was conducted from Feb to June 2017. The different parameters measured with the help of a vernier caliper, foot scale, digital weighing machine. Body parameters were measured via; length of body, length of the wings, length of tail, mass in grams. During present study, a total number of 36 specimens were collected from different localities of City Mirpurkhas (38.2%) were male and (62.7%) were female. Maximum population density of Psittaculla Krameri borealis (52.9%) was collected from Sindh Horticulture Research Station (fruit farm) Mirpurkhas. Minimum no: of Psittaculla krameri borealis (5.5%) collected in urban parks. It was observed that Psittaculla krameri borealis were in dense population during the months of ‘May’ and ‘June’ when the temperature ranged between 20°C and 45°C. A Psittaculla krameri borealis female was found the heaviest in body weight. The species of parrot (rose ringed) captured during study having green plumage, coverts were gray, upper beak, red and lower beak black, shorter tail in female long tail in the male which was similar to the Psittaculla krameri borealis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mirpurkhas%20Sindh%20Pakistan" title="Mirpurkhas Sindh Pakistan">Mirpurkhas Sindh Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20ecology" title=" environmental ecology"> environmental ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=parrot" title=" parrot"> parrot</a>, <a href="https://publications.waset.org/abstracts/search?q=rose-ringed" title=" rose-ringed"> rose-ringed</a>, <a href="https://publications.waset.org/abstracts/search?q=taxonomy" title=" taxonomy"> taxonomy</a> </p> <a href="https://publications.waset.org/abstracts/91684/taxonomic-study-and-environmental-ecology-of-parrot-rose-ringed-in-city-mirpurkhas-sindh-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91684.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">175</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">209</span> Degradation of Rose Bengal by UV in the Presence of NiFe2O4 Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Boucheloukh">H.

While these collections are very useful for the enrichment of knowledge and are considered as natural heritage of our entire world, it is very important to preserve and conserve them. The significance is not only to prevent the herbaria from the deterioration of biological agencies but also to preserve its colours and retain natural colour. Colour is not only characteristic of a plant, but it can also help to identify closely related species or to distinguish a plant from a collection of herbaria. Keeping this in mind, a selective solution has been prepared for the conservation and preservation of herbarium in the present study. In this, the quantity of all the selected chemicals, i.e., formaldehyde and copper sulphate was kept constant, and the solution was prepared by dissolving it in distilled water by increasing the amount of picric acid (1, 2, 3, 4, and 5 ml). Fresh specimens of roses and bougainvillea were washed with distilled water and kept in the above solution for 10 to 15 minutes at room temperature. After 10 minutes, the specimen was removed from the solution, dried with the help of paper, and then pressed under the plant press. Blotting sheets were used to absorb the moisture content and were changed every 2 to 3 days to protect against fungal growth. The results revealed that all solutions had insecticidal properties and protected the herbarium specimen against pests. While in the case of colour retention, solution-1 and 2 were not satisfactory colour preservation, and solutions-3 and 5 maintained the colour of rose and bougainvillea leaves for 15 to 20 days and for a month, respectively. After that, the colour begins to fade, and the process is faster in rose leaves than in bougainvillea. And it was also observed that the colour of young leaves started to fade before that of older leaves. When the leaves of rose and bougainvillea are treated with Solution-4, then the colour of rose leaves is maintained for six months. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solutions" title="solutions">solutions</a>, <a href="https://publications.waset.org/abstracts/search?q=colour%20retention" title=" colour retention"> colour retention</a>, <a href="https://publications.waset.org/abstracts/search?q=preservation%20and%20conservation" title=" preservation and conservation"> preservation and conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=leaves%20of%20roses%20and%20bougainvillea" title=" leaves of roses and bougainvillea"> leaves of roses and bougainvillea</a> </p> <a href="https://publications.waset.org/abstracts/153068/an-advanced-method-of-plant-preservation-and-colour-retention-of-herbarium-specimens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153068.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">93</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">206</span> Exploring Polypnenolics Content and Antioxidant Activity of R. damascena Dry Extract by Spectroscopic and Chromatographic Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Nedeltcheva-Antonova">Daniela Nedeltcheva-Antonova</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamelia%20Getchovska"> Kamelia Getchovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Vera%20Deneva"> Vera Deneva</a>, <a href="https://publications.waset.org/abstracts/search?q=Stanislav%20Bozhanov"> Stanislav Bozhanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Liudmil%20Antonov"> Liudmil Antonov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rosa damascena Mill. (Damask rose) is one of the most important plants belonging to the Rosaceae family, with a long historical use in traditional medicine and as a valuable oil-bearing plant. Many pharmacological effects have been reported from this plant, including anti-inflammatory, hypnotic, analgesic, anticonvulsant, anti-depressant, antianxiety, antitussive, antidiabetic, relaxant effects on tracheal chains, laxative, prokinetic and hepatoprotective activities. Pharmacological studies have shown that the various health effects of R. damascena flowers can mainly be attributed to its large amount of polyphenolic components. Phenolics possess a wide range of pharmacological activities, such as antioxidants, free-radical scavengers, anticancer, anti-inflammatory, antimutagenic, and antidepressant, with flavonoids being the most numerous group of natural polyphenolic compounds. According to the technological process in the production of rose concrete (solvent extraction with non-polar solvents of fresh rose flowers), it can be assumed that the resulting plant residue would be as rich of polyphenolics, as the plant itself, and could be used for the development of novel products with promising health-promoting effect. Therefore, an optimisation of the extraction procedure of the by-product from the rose concrete production was carried out. An assay of the extracts in respect of their total polyphenols and total flavonoids content was performed. HPLC analysis of quercetin and kaempferol, the two main flavonoids found in R. damascena, was also carried out. The preliminary results have shown that the flavonoid content in the rose extracts is comparable to that of the green tea or Gingko biloba, and they could be used for the development of various products (food supplements, natural cosmetics and phyto-pharmaceutical formulation, etc.). The fact that they are derived from the by-product of industrial plant processing could add the marketing value of the final products in addition to the well-known reputation of the products obtained from Bulgarian roses (R. damascena Mill.). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography-mass-spectromrtry" title="gas chromatography-mass-spectromrtry">gas chromatography-mass-spectromrtry</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20extract" title=" dry extract"> dry extract</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20damascena%20Mill" title=" Rosa damascena Mill"> Rosa damascena Mill</a> </p> <a href="https://publications.waset.org/abstracts/115745/exploring-polypnenolics-content-and-antioxidant-activity-of-r-damascena-dry-extract-by-spectroscopic-and-chromatographic-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115745.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">205</span> Directional Dust Deposition Measurements: The Influence of Seasonal Changes and the Meteorological Conditions Influencing in Witbank Area and Carletonville Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maphuti%20Georgina%20Kwata">Maphuti Georgina Kwata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coal mining in Mpumalanga Province is known of contributing to the atmospheric pollution from various activities. Gold mining in North-West Province is known of also contributing to the atmospheric pollution especially with the production of radon gas. In this research directional dust deposition gauge was used to measure source of direction and meteorological data was used to determine the wind rose blowing and the influence of the seasonal changes. Fourteen months of dust collection was undertaken in Witbank Area and Carletonville Area. The results shows that the sources of direction for Ericson Dam its East in February 2010 and Tip Area shows that the source of direction its West in October 2010. In the East direction there were mining operations, power stations which contributed to the East to be the sources of direction. In the West direction there were smelters, power stations and agricultural activities which contributed for the source of direction to be the West direction for Driefontein Mine: East Recreational Village Club. The East of Leslie Williams hospital is the source of direction which also indicated that there dust generating activities such as mining operation, agricultural activities. The meteorological results for Emalahleni Area in summer and winter the wind rose blow with wind speed of 5-10 ms-1 from the East sector. Annual average for the wind rose blow its East South eastern sector with 20 ms-1 and day time the wind rose from northwestern sector with excess of 20 ms-1. The night time wind direction East-eastern direction with a maximum wind speed of 20 ms-1. The meteorogical results for Driefontein Mine show that North-western sector and north-eastern sector wind rose is blowing with 5-10 ms-1 win speed. Day time wind blows from the West sector and night time wind blows from the north sector. In summer the wind blows North-east sector with 5-10 ms-1 and winter wind blows from North-west and it’s also predominant. In spring wind blows from north-east. The conclusion is that not only mining operation where the directional dust deposit gauge were installed contributed to the source of direction also the power stations, smelters, and other activities nearby the mining operation contributed. The recommendations are the dust suppressant for unpaved roads should be used on a regular basis and there should be monitoring of the weather conditions (the wind speed and direction prior to blasting to ensure minimal emissions). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=directional%20dust%20deposition%20gauge" title="directional dust deposition gauge">directional dust deposition gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=BS%20part%205%201747%20dust%20deposit%20gauge" title=" BS part 5 1747 dust deposit gauge"> BS part 5 1747 dust deposit gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20rose" title=" wind rose"> wind rose</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20blowing" title=" wind blowing"> wind blowing</a> </p> <a href="https://publications.waset.org/abstracts/23436/directional-dust-deposition-measurements-the-influence-of-seasonal-changes-and-the-meteorological-conditions-influencing-in-witbank-area-and-carletonville-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23436.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">505</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">204</span> CuFeOx-Based Nano-Rose Electrocatalysts for Oxygen Evolution Reaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamad%20Almohamadi">Hamad Almohamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabeel%20H.%20Alharthi"> Nabeel H.

The findings showed that the thrips started to build up their population from the middle of January with abundance 1.0 leaf⁻¹, increased continuously, reached to the peak level (2.6 leaf⁻¹) in the middle of February and then declined. Aphid started to build up their population from the second week of November with abundance 6.0 leaf⁻¹, increased continuously, reached to the peak level (8.4 leaf⁻¹) in the last week of December and then declined. Mite started to build up their population from the first week of December with abundance 0.8 leaf⁻¹, increased continuously, reached to the peak level (8.2 leaf⁻¹) in the second week of March and then declined. Thrips and mite prevailed until the last week of April, and aphid showed their abundance till last week of May. The daily mean temperature, relative humidity, and rainfall had an insignificant negative correlation with thrips and significant negative correlation with aphid abundance. The daily mean temperature had significant positive, relative humidity had an insignificant positive, and rainfall had an insignificant negative correlation with mite abundance. The multiple linear regression analysis showed that the weather parameters together contributed 38.1, 41.0 and 8.9% abundance on thrips, aphid and mite on rose, respectively and the equations were insignificant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aphid" title="aphid">aphid</a>, <a href="https://publications.waset.org/abstracts/search?q=mite" title=" mite"> mite</a>, <a href="https://publications.waset.org/abstracts/search?q=thrips" title=" thrips"> thrips</a>, <a href="https://publications.waset.org/abstracts/search?q=weather%20factors" title=" weather factors"> weather factors</a> </p> <a href="https://publications.waset.org/abstracts/103991/major-sucking-pests-of-rose-and-their-seasonal-abundance-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103991.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">161</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">202</span> The Acquisition of /r/ By Setswana-Learning Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keneilwe%20Matlhaku">Keneilwe Matlhaku</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crosslinguistic studies (theoretical and clinical) have shown delays and significant misarticulation in the acquisition of the rhotics. This article provides a detailed analysis of the early development of the rhotic phoneme, an apical trill /r/, by monolingual Setswana (Tswana S30) children of age ranges between 1 and 4 years. The data display the following trends: (1) late acquisition of /r/; (2) a wide range of substitution patterns involving this phoneme (i.e., gliding, coronal stopping, affrication, deletion, lateralization, as well as, substitution to a dental and uvular fricative). The primary focus of the article is on the potential origins of these variations of /r/, even within the same language. Our data comprises naturalistic longitudinal audio recordings of 6 children (2 males and 4 females) whose speech was recorded in their homes over a period of 4 months with no or only minimal disruptions in their daily environments. Phon software (Rose et al. 2013; Rose & MacWhinney 2014) was used to carry out the orthographic and phonetic transcriptions of the children’s data. Phon also enabled the generation of the children’s phonological inventories for comparison with adult target IPA forms. We explain the children’s patterns through current models of phonological emergence (MacWhinney 2015) as well as McAllister Byun, Inkelas & Rose (2016); Rose et al., (2022), which highlight the perceptual and articulatory factors influencing the development of sounds and sound classes. We highlight how the substitution patterns observed in the data can be captured through a consideration of the auditory properties of the target speech sounds, combined with an understanding of the types of articulatory gestures involved in the production of these sounds. These considerations, in turn, highlight some of the most central aspects of the challenges faced by the child toward learning these auditory-articulatory mappings. We provide a cross-linguistic survey of the acquisition of rhotic consonants in a sample of related and unrelated languages in which we show that the variability and volatility in the substitution patterns of /r/ is also brought about by the properties of the children’s ambient languages. Beyond theoretical issues, this article sets an initial foundation for developing speech-language pathology materials and services for Setswana learning children, an emerging area of public service in Botswana. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhotic" title="rhotic">rhotic</a>, <a href="https://publications.waset.org/abstracts/search?q=apical%20trill" title=" apical trill"> apical trill</a>, <a href="https://publications.waset.org/abstracts/search?q=Phon" title=" Phon"> Phon</a>, <a href="https://publications.waset.org/abstracts/search?q=phonological%20emergence" title=" phonological emergence"> phonological emergence</a>, <a href="https://publications.waset.org/abstracts/search?q=auditory" title=" auditory"> auditory</a>, <a href="https://publications.waset.org/abstracts/search?q=articulatory" title=" articulatory"> articulatory</a>, <a href="https://publications.waset.org/abstracts/search?q=mapping" title=" mapping"> mapping</a> </p> <a href="https://publications.waset.org/abstracts/187568/the-acquisition-of-r-by-setswana-learning-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187568.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">38</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">201</span> The Women's Orchestra and Music in Auschwitz-Birkenau: A Qualitative Study on Nazi Manipulation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20T.%20%20Kohler">K.

Led by Gustav Mahler’s granddaughter, Alma Rosé, the orchestra rhythmed the life cycle of the camp, from marching to and from work, Sunday concerts, welcoming transports, to the prisoners’ walk to gas chambers. What surfaced from these testimonies was that the more technical the exposure a woman had to music before camp, the more disturbing its effect. The juxtaposition of beauty with the visible horror of the camp thrust them into an impossible state where suicide became a plausible alternative. By exploiting the Women’s Orchestra, the Nazis made music a critical component of manipulation within Auschwitz-Birkenau. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alma%20Ros%C3%A9" title="Alma Rosé">Alma Rosé</a>, <a href="https://publications.waset.org/abstracts/search?q=Auschwitz-Birkenau" title=" Auschwitz-Birkenau"> Auschwitz-Birkenau</a>, <a href="https://publications.waset.org/abstracts/search?q=camp%20life" title=" camp life"> camp life</a>, <a href="https://publications.waset.org/abstracts/search?q=concert" title=" concert"> concert</a>, <a href="https://publications.waset.org/abstracts/search?q=Holocaust" title=" Holocaust"> Holocaust</a>, <a href="https://publications.waset.org/abstracts/search?q=music" title=" music"> music</a>, <a href="https://publications.waset.org/abstracts/search?q=O%C5%9Bwi%C4%99cim" title=" Oświęcim"> Oświęcim</a>, <a href="https://publications.waset.org/abstracts/search?q=Poland" title=" Poland"> Poland</a>, <a href="https://publications.waset.org/abstracts/search?q=women%E2%80%99s%20orchestra" title=" women’s orchestra "> women’s orchestra </a> </p> <a href="https://publications.waset.org/abstracts/102510/the-womens-orchestra-and-music-in-auschwitz-birkenau-a-qualitative-study-on-nazi-manipulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102510.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">185</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">200</span> Comparison of Spiking Neuron Models in Terms of Biological Neuron Behaviours</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fikret%20Yalcinkaya">Fikret Yalcinkaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Unsal"> Hamza Unsal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To understand how neurons work, it is required to combine experimental studies on neural science with numerical simulations of neuron models in a computer environment. In this regard, the simplicity and applicability of spiking neuron modeling functions have been of great interest in computational neuron science and numerical neuroscience in recent years. Spiking neuron models can be classified by exhibiting various neuronal behaviors, such as spiking and bursting. These classifications are important for researchers working on theoretical neuroscience. In this paper, three different spiking neuron models; Izhikevich, Adaptive Exponential Integrate Fire (AEIF) and Hindmarsh Rose (HR), which are based on first order differential equations, are discussed and compared. First, the physical meanings, derivatives, and differential equations of each model are provided and simulated in the Matlab environment. Then, by selecting appropriate parameters, the models were visually examined in the Matlab environment and it was aimed to demonstrate which model can simulate well-known biological neuron behaviours such as Tonic Spiking, Tonic Bursting, Mixed Mode Firing, Spike Frequency Adaptation, Resonator and Integrator. As a result, the Izhikevich model has been shown to perform Regular Spiking, Continuous Explosion, Intrinsically Bursting, Thalmo Cortical, Low-Threshold Spiking and Resonator. The Adaptive Exponential Integrate Fire model has been able to produce firing patterns such as Regular Ignition, Adaptive Ignition, Initially Explosive Ignition, Regular Explosive Ignition, Delayed Ignition, Delayed Regular Explosive Ignition, Temporary Ignition and Irregular Ignition. The Hindmarsh Rose model showed three different dynamic neuron behaviours; Spike, Burst and Chaotic. From these results, the Izhikevich cell model may be preferred due to its ability to reflect the true behavior of the nerve cell, the ability to produce different types of spikes, and the suitability for use in larger scale brain models. The most important reason for choosing the Adaptive Exponential Integrate Fire model is that it can create rich ignition patterns with fewer parameters. The chaotic behaviours of the Hindmarsh Rose neuron model, like some chaotic systems, is thought to be used in many scientific and engineering applications such as physics, secure communication and signal processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Izhikevich" title="Izhikevich">Izhikevich</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20exponential%20integrate%20fire" title=" adaptive exponential integrate fire"> adaptive exponential integrate fire</a>, <a href="https://publications.waset.org/abstracts/search?q=Hindmarsh%20Rose" title=" Hindmarsh Rose"> Hindmarsh Rose</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20neuron%20behaviours" title=" biological neuron behaviours"> biological neuron behaviours</a>, <a href="https://publications.waset.org/abstracts/search?q=spiking%20neuron%20models" title=" spiking neuron models"> spiking neuron models</a> </p> <a href="https://publications.waset.org/abstracts/91443/comparison-of-spiking-neuron-models-in-terms-of-biological-neuron-behaviours" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91443.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">180</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">199</span> Eradication of Gram-Positive Bacteria by Photosensitizers Immobilized in Polymers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Nisnevitch">Marina Nisnevitch</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Valkov"> Anton Valkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Faina%20Nakonechny"> Faina Nakonechny</a>, <a href="https://publications.waset.org/abstracts/search?q=Kate%20Adar%20Raik"> Kate Adar Raik</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamit%20Mualem"> Yamit Mualem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Photosensitizers are dye compounds belonging to various chemical groups that in all the cases have a developed structure of conjugated double bonds. Under illumination with visible light, the photosensitizers are excited and transfer the absorbed energy to the oxygen dissolved in an aqueous phase, leading to production of a reactive oxygen species which cause irreversible damage to bacterial cells. When immobilized onto a solid phase, photosensitizers preserve their antibacterial properties. In the present study, photosensitizers were immobilized in polyethylene or propylene and tested for antimicrobial activity against Gram-positive S. aureus, S. epidermidis and Streptococcus sp. For this purpose, water-soluble photosensitizers, Rose Bengal sodium salt, and methylene blue as well as water-insoluble hematoporphyrin and Rose Bengal lactone, were immobilized by dissolution in melted polymers to yield 3 mm diameter rods and 3-5 mm beads. All four photosensitizers were found to be effective in the eradication of Gram-positive bacteria under illumination by a white luminescent lamp or sunlight. The immobilized photosensitizers can be applied for continuous water disinfection; they can be easily removed at the end of the treatment and reused. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20polymers" title="antimicrobial polymers">antimicrobial polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=gram-positive%20bacteria" title=" gram-positive bacteria"> gram-positive bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization%20of%20photosensitizers" title=" immobilization of photosensitizers"> immobilization of photosensitizers</a>, <a href="https://publications.waset.org/abstracts/search?q=photodynamic%20antibacterial%20activity" title=" photodynamic antibacterial activity"> photodynamic antibacterial activity</a> </p> <a href="https://publications.waset.org/abstracts/46641/eradication-of-gram-positive-bacteria-by-photosensitizers-immobilized-in-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46641.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">241</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">198</span> A Comparison of Biosorption of Radionuclides Tl-201 on Different Biosorbents and Their Empirical Modelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sinan%20Yapici">Sinan Yapici</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayrettin%20Eroglu"> Hayrettin Eroglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The discharge of the aqueous radionuclides wastes used for the diagnoses of diseases and treatments of patients in nuclear medicine can cause fatal health problems when the radionuclides and its stable daughter component mix with underground water. Tl-201, which is one of the radionuclides commonly used in the nuclear medicine, is a toxic substance and is converted to its stable daughter component Hg-201, which is also a poisonous heavy metal: Tl201 → Hg201 + Gamma Ray [135-167 Kev (12%)] + X Ray [69-83 Kev (88%)]; t1/2 = 73,1 h. The purpose of the present work was to remove Tl-201 radionuclides from aqueous solution by biosorption on the solid bio wastes of food and cosmetic industry as bio sorbents of prina from an olive oil plant, rose residue from a rose oil plant and tea residue from a tea plant, and to make a comparison of the biosorption efficiencies. The effects of the biosorption temperature, initial pH of the aqueous solution, bio sorbent dose, particle size and stirring speed on the biosorption yield were investigated in a batch process. It was observed that the biosorption is a rapid process with an equilibrium time less than 10 minutes for all the bio sorbents. The efficiencies were found to be close to each other and measured maximum efficiencies were 93,30 percent for rose residue, 94,1 for prina and 98,4 for tea residue. In a temperature range of 283 and 313 K, the adsorption decreased with increasing temperature almost in a similar way. In a pH range of 2-10, increasing pH enhanced biosorption efficiency up to pH=7 and then the efficiency remained constant in a similar path for all the biosorbents. Increasing stirring speed from 360 to 720 rpm enhanced slightly the biosorption efficiency almost at the same ratio for all bio sorbents. Increasing particle size decreased the efficiency for all biosorbent; however the most negatively effected biosorbent was prina with a decrease in biosorption efficiency from about 84 percent to 40 with an increase in the nominal particle size 0,181 mm to 1,05 while the least effected one, tea residue, went down from about 97 percent to 87,5. The biosorption efficiencies of all the bio sorbents increased with increasing biosorbent dose in the range of 1,5 to 15,0 g/L in a similar manner. The fit of the experimental results to the adsorption isotherms proved that the biosorption process for all the bio sorbents can be represented best by Freundlich model. The kinetic analysis showed that all the processes fit very well to pseudo second order rate model. The thermodynamics calculations gave ∆G values between -8636 J mol-1 and -5378 for tea residue, -5313 and -3343 for rose residue, and -5701 and -3642 for prina with a ∆H values of -39516 J mol-1, -23660 and -26190, and ∆S values of -108.8 J mol-1 K-1, -64,0, -72,0 respectively, showing spontaneous and exothermic character of the processes. An empirical biosorption model in the following form was derived for each biosorbent as function of the parameters and time, taking into account the form of kinetic model, with regression coefficients over 0.9990 where At is biosorbtion efficiency at any time and Ae is the equilibrium efficiency, t is adsorption period as s, ko a constant, pH the initial acidity of biosorption medium, w the stirring speed as s-1, S the biosorbent dose as g L-1, D the particle size as m, and a, b, c, and e are the powers of the parameters, respectively, E a constant containing activation energy and T the temperature as K. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiation" title="radiation">radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=diosorption" title=" diosorption"> diosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=thallium" title=" thallium"> thallium</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20modelling" title=" empirical modelling"> empirical modelling</a> </p> <a href="https://publications.waset.org/abstracts/12849/a-comparison-of-biosorption-of-radionuclides-tl-201-on-different-biosorbents-and-their-empirical-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12849.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">265</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">197</span> Peak Frequencies in the Collective Membrane Potential of a Hindmarsh-Rose Small-World Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun%20Zhe">Sun Zhe</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruggero%20Micheletto"> Ruggero Micheletto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As discussed extensively in many studies, noise in neural networks have an important role in the functioning and time evolution of the system. The mechanism by which noise induce stochastic resonance enhancing and influencing certain operations is not clarified nor is the mechanism of information storage and coding. With the present research we want to study the role of noise, especially focusing on the frequency peaks in a three variable Hindmarsh−Rose Small−World network. We investigated the behaviour of the network to external noises. We demonstrate that a variation of signal to noise ratio of about 10 dB induces an increase in membrane potential signal of about 15%, averaged over the whole network. We also considered the integral of the whole membrane potential as a paradigm of internal noise, the one generated by the brain network. We showed that this internal noise is attenuated with the size of the network or with the number of random connections. By means of Fourier analysis we found that it has distinct peaks of frequencies, moreover, we showed that increasing the size of the network introducing more neurons, reduced the maximum frequencies generated by the network, whereas the increase in the number of random connections (determined by the small-world probability p) led to a trend toward higher frequencies. This study may give clues on how networks utilize noise to alter the collective behaviour of the system in their operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title="neural networks">neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20processes" title=" stochastic processes"> stochastic processes</a>, <a href="https://publications.waset.org/abstracts/search?q=small-world%20networks" title=" small-world networks"> small-world networks</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20Fourier%20analysis" title=" discrete Fourier analysis"> discrete Fourier analysis</a> </p> <a href="https://publications.waset.org/abstracts/27187/peak-frequencies-in-the-collective-membrane-potential-of-a-hindmarsh-rose-small-world-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27187.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">291</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">196</span> Contact Toxicity Effects of Different Formulations of Artemisia Absinthium Extracts on Rose Aphid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Atapour">Maryam Atapour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chemical pesticides, which are widely used in agriculture, cause problems such as soil and water pollution, reducing biodiversity and creating pest resistance. These problems have led to increased attention to alternative and more sustainable methods such as natural-based pesticides. Herbal pesticides have been developed based on essential oils or extracts from different parts of plants, such as leaves, roots, and flowers. Herbal pesticides are compatible with the environment and can be used in integrated pest management programs. Despite the many benefits, herbal pesticides, especially essential oil-based compounds, have low durability in the environment, and their production costs are high, so the use of herbal extracts with appropriate formulations is more justified in all aspects. In the current study and based on the results of previous studies, aqueous and 70% ethanolic extract of Artemisia absinthium L. was prepared by the percolation method and formulated as an emulsion and water-soluble powder. To produce powder formulation, 20% maltodextrin was used with the spray-dryer method. Different concentrations of these compounds were sprayed on bushes infected with rose aphid Macrosiphum rosae (L.). Sampling was done randomly and the percentage of aphids’ mortality was checked. The results showed that the use of different concentrations of ethanolic extracts created a significant difference in the mortality rate of aphids, while water-soluble powder formulation caused less mortality. The current results showed that the extract of this plant has practical usability to control aphids, and with the appropriate formulation, it can be used as a good alternative to chemical pesticides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20toxicity" title="contact toxicity">contact toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=formulation" title=" formulation"> formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=extract" title=" extract"> extract</a>, <a href="https://publications.waset.org/abstracts/search?q=aphid" title=" aphid"> aphid</a>, <a href="https://publications.waset.org/abstracts/search?q=Artemisia%20absinthium." title=" Artemisia absinthium."> Artemisia absinthium.</a> </p> <a href="https://publications.waset.org/abstracts/187446/contact-toxicity-effects-of-different-formulations-of-artemisia-absinthium-extracts-on-rose-aphid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187446.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">36</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">195</span> Regulating Issues concerning Data Protection in Cloud Computing: Developing a Saudi Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jumana%20Majdi%20Qutub">Jumana Majdi Qutub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rationale: Cloud computing has rapidly developed the past few years. Because of the importance of providing protection for personal data used in cloud computing, the role of data protection in promoting trust and confidence in users’ data has become an important policy priority. This research examines key regulatory challenges rose by the growing use and importance of cloud computing with focusing on protection of individuals personal data. Methodology: Describing and analyzing governance challenges facing policymakers and industry in Saudi Arabia, with an account of anticipated governance responses. The aim of the research is to describe and define the regulatory challenges on cloud computing for policy making in Saudi Arabia and comparing it with potential complied issues rose in respect of transported data to EU member state. In addition, it discusses information privacy issues. Finally, the research proposes policy recommendation that would resolve concerns surrounds the privacy and effectiveness of clouds computing frameworks for data protection. Results: There are still no clear regulation in Saudi Arabia specialized in legalizing cloud computing and specialty regulations in transferring data internationally and locally. Decision makers need to review the applicable law in Saudi Arabia that protect information in cloud computing. This should be from an international and a local view in order to identify all requirements surrounding this area. It is important to educate cloud computing users about their information value and rights before putting it in the cloud to avoid further legal complications, such as making an educational program to prevent giving personal information to a bank employee. Therefore, with many kinds of cloud computing services, it is important to have it covered by the law in all aspects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20crime" title=" cyber crime"> cyber crime</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20protection" title=" data protection"> data protection</a>, <a href="https://publications.waset.org/abstracts/search?q=privacy" title=" privacy"> privacy</a> </p> <a href="https://publications.waset.org/abstracts/62257/regulating-issues-concerning-data-protection-in-cloud-computing-developing-a-saudi-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62257.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">260</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">194</span> Screening of Antiviral Compounds in Medicinal Plants: Non-Volatiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Drevinskas">Tomas Drevinskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruta%20Mickiene"> Ruta Mickiene</a>, <a href="https://publications.waset.org/abstracts/search?q=Audrius%20Maruska"> Audrius Maruska</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Tiso"> Nicola Tiso</a>, <a href="https://publications.waset.org/abstracts/search?q=Algirdas%20Salomskas"> Algirdas Salomskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Raimundas%20Lelesius"> Raimundas Lelesius</a>, <a href="https://publications.waset.org/abstracts/search?q=Agneta%20Karpovaite"> Agneta Karpovaite</a>, <a href="https://publications.waset.org/abstracts/search?q=Ona%20Ragazinskiene"> Ona Ragazinskiene</a>, <a href="https://publications.waset.org/abstracts/search?q=Loreta%20Kubiliene"> Loreta Kubiliene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antiviral effect of substances accumulated by plants and natural products is known to ethno-pharmacy and modern day medicine. Antiviral properties are usually assigned to volatile compounds and polyphenols. This research work is divided into several parts and the task of this part was to investigate potential plants, potential substances and potential preparation conditions that can be used for the preparation of antiviral agents. Sixteen different medicinal plants, their parts and two types of propolis were selected for screening. Firstly, extraction conditions of non-volatile compounds were investigated: 3 pre-selected plants were extracted with 5 different ethanol – water mixtures (96%, 75%, 60%, 40%, 20 %, vol.) and bidistilled water. Total phenolic content, total flavonoid content and radical scavenging activity was determined. The results indicated that optimal extrahent is 40%, vol. of ethanol – water mixture. Further investigations were performed with the extrahent of 40%, vol. ethanol – water mixture. All 16 of selected plants, their parts and two types of propolis were extracted using selected extrahent. Determined total phenolic content, total flavonoid content and radical scavenging activity indicated that extracts of Origanum Vulgare L., Mentha piperita L., Geranium macrorrhizum L., Melissa officinalis L. and Desmodium canadence L. contains highest amount of extractable phenolic compounds (7.31, 5.48, 7.88, 8.02 and 7.16 rutin equivalents (mg/ ml) respectively), flavonoid content (2.14, 2.23, 2.49, 0.79 and 1.51 rutin equivalents (mg/ml) respectively) and radical scavenging activity (11.98, 8.72, 13.47, 13.22 and 12.22 rutin equivalents (mg/ml) respectively).

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. The above said scientific interventions making organic farming a charming proposition would be discussed in details. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20agriculture" title="organic agriculture">organic agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20inoculants" title=" microbial inoculants"> microbial inoculants</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20fertilizers" title=" organic fertilizers"> organic fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20plant%20growth%20promoters" title=" natural plant growth promoters"> natural plant growth promoters</a> </p> <a href="https://publications.waset.org/abstracts/60559/equipping-organic-farming-in-medicinal-and-aromatic-plants-central-institute-of-medicinal-and-aromatic-plants-scientific-interventions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60559.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">237</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">192</span> Optimal Energy Consumption with Semiconductor Lamps</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pejman%20Hosseiniun">Pejman Hosseiniun</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20Shayeghi"> Rose Shayeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Farzaneh"> Alireza Farzaneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolghasem%20Ghasempour"> Abolghasem Ghasempour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using LED lamps as lighting resources with new technology in designing lighting systems has been studied in this article.

Finally, there is a comparison between these lamps and ordinary lamps to assess light parameters as well as energy consumption using DIALux software. Considering the results of analogies LED lamps have lower consumption and more lighting yield, therefore they are more economically feasible. Color variety, longer usage lap (circa 10 years) and compatibility with DC voltages are other LED lamps perquisites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LED" title="LED">LED</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting%20efficiency" title=" lighting efficiency"> lighting efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting%20intensity" title=" lighting intensity"> lighting intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=luminance" title=" luminance"> luminance</a> </p> <a href="https://publications.waset.org/abstracts/30378/optimal-energy-consumption-with-semiconductor-lamps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30378.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">593</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">191</span> Cadmium Accumulation and Depuration Characteristics through Food Source of Cage-Cultivated Fish after Accidental Pollution in Longjiang River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qianli%20Ma">Qianli Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuemin%20Zhao"> Xuemin Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingai%20Yao"> Lingai Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhencheng%20Xu"> Zhencheng Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Wang"> Li Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metal pollution accidents, frequently happened in this decade in China, severely threaten aquatic ecosystem and economy. In January 2012, a basin-scale accidental Cd pollution happened in Longjiang River in southwest China. Although water quality was recovered in short period by emergency treatment with flocculants, a large amount of contaminated cage-cultivated fish were left with the task of preventing or mitigating Cd contamination of fish. In this study, unpolluted Ctenopharyngodon idellus were fed by Cd-contaminated macrophytes for assessing the effect of Cd accumulation through food exposure, and the contaminated C. idellus were fed with Cd-free macrophytes for assessing the ability of Cd depuration. The on-site cultivation experiments were done in two sites of Lalang (S1, accidental Cd pollution originated) and Sancha (S2, a large amount of flocculants were added to accelerate Cd precipitation) in Longjiang river. Results showed that Cd content in fish muscle presented an increasing trend in the accumulation experiment. In S1, Cd content of fish muscle rose sharply from day 8 to day 18 with higher average Cd content in macrophytes and sediment, and kept in the range of 0.208-0.308 mg/kg afterward. In S2, Cd content of fish muscle rose gradually throughout the experiment and reached the maximum level of 0.285 mg/kg on day 76. The results of the depuration experiment showed that Cd content in fish muscle decreased and significant changes were observed in the first half time of the experiment. Meanwhile, fish with lower initial Cd content presented higher elimination constant. In S1, Cd content of fish significantly decreased from 0.713 to 0.304 mg/kg in 18 days and kept decreasing to 0.110 mg/kg in the end, and 84.6% of Cd content was eliminated. While in S2, there was a sharp decrease of Cd content of fish in 0-8 days from 0.355 mg/kg to 0.069 mg/kg. The total elimination percentage was 93.8% and 80.6% of which appeared in day 0-8. The elimination constant of fish in S2 was 0.03 which was higher than 0.02 in S1. Collectively, our results showed Cd could be absorbed through food exposure and accumulate in fish muscle, and the accumulated Cd in fish muscle can be excreted after isolated from the polluted food sources. This knowledge allows managers to assess health risk of Cd contaminated fish and minimize aquaculture loss when considering fish cultivation after accidental pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accidental%20pollution" title="accidental pollution">accidental pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium%20accumulation%20and%20depuration" title=" cadmium accumulation and depuration"> cadmium accumulation and depuration</a>, <a href="https://publications.waset.org/abstracts/search?q=cage-cultivated%20fish" title=" cage-cultivated fish"> cage-cultivated fish</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20management" title=" environmental management"> environmental management</a>, <a href="https://publications.waset.org/abstracts/search?q=river" title=" river"> river</a> </p> <a href="https://publications.waset.org/abstracts/74446/cadmium-accumulation-and-depuration-characteristics-through-food-source-of-cage-cultivated-fish-after-accidental-pollution-in-longjiang-river" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74446.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">253</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">190</span> Transformative Learning and the Development of Cultural Humility in Social Work Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruilin%20Zhu">Ruilin Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Olco%C5%84"> Katarzyna Olcoń</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20M.%20Pulliam"> Rose M.

Nevertheless, experiments for subjecting liquids which have not too small volumes to negative pressures are difficult even now. The reason of the difficulties is because the liquids tend to generate cavities easily. In order to remove cavitation nuclei, an apparatus for enclosing water into a metal Berthelot tube under vacuum conditions was developed. By using the apparatus, negative pressures for water rose to ca. -20 MPa. This is the highest value for water in metal Berthelot tubes. Results were explained by a traditional crevice model.

Research shows that even a glance at nature can evoke positive feelings in the person and reduce his tension and stress. According to the historical, cultural, religious, and individual background in each geographical district, the relaxing or spiritual impact of certain kinds of flowers can be evaluated. In this paper, using a questionnaire, the amount of relaxing impact of prevalent trees and flowers of the district on the patients was examined. The results showed that cedar and pomegranate trees and jasmine and rose in flowers, respectively, relax the patients. <p class="card-text"><strong>Keywords:</strong> <a
