In everyday usage of a language, words are used, and new words are formed and reformed to contain and accommodate all entities, phenomena, qualities and every aspect of the entire life. Despite the fact that many studies have been conducted on morphological processes in The Hausa language. Most of the works concentrated on borrowing, affixation, reduplication and derivation, but blending has been neglected to the extent that some of the Hausa linguists claim that, blending does not exist in the language. Therefore, the current study investigates and examines blending as one of the word formation processes' in the language. The study focuses its main attention on blending as a word-formation process and how this process is used adequately in the formation of words in The Hausa language. To achieve the aims, the research answered these questions: 1) is blending used as a process of word formation in Hausa? 2) What are the words formed using this process? This study utilizes the Natural Morphology Theory proposed by Dressler, (1985) which was adopted by Belly (2007). The data of this study have been collected from newspaper articles, novels, and written literature of Hausa language. Based on the findings, this study found out that, there exist new kind of words formed in The Hausa language under blending, which previous findings did not either reveal or explain in detail. Another part of the finding shows that some of the words change their grammatical classes and meaning while blended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=morphology" title="morphology">morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=word%20formation" title=" word formation"> word formation</a>, <a href="https://publications.waset.org/abstracts/search?q=blending%20in%20hausa%20language" title=" blending in hausa language"> blending in hausa language</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a> </p> <a href="https://publications.waset.org/abstracts/22333/formation-of-blends-in-hausa-language" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22333.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">419</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> Computationally Efficient Stacking Sequence Blending for Composite Structures with a Large Number of Design Regions Using Cellular Automata</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ellen%20Van%20Den%20Oord">Ellen Van Den Oord</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Marie%20Jan%20Ferdinand%20Van%20Campen"> Julien Marie Jan Ferdinand Van Campen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article introduces a computationally efficient method for stacking sequence blending of composite structures. The computational efficiency makes the presented method especially interesting for composite structures with a large number of design regions. Optimization of composite structures with an unequal load distribution may lead to locally optimized thicknesses and ply orientations that are incompatible with one another. Blending constraints can be enforced to achieve structural continuity. In literature, many methods can be found to implement structural continuity by means of stacking sequence blending in one way or another. The complexity of the problem makes the blending of a structure with a large number of adjacent design regions, and thus stacking sequences, prohibitive. In this work the local stacking sequence optimization is preconditioned using a method found in the literature that couples the mechanical behavior of the laminate, in the form of lamination parameters, to blending constraints, yielding near-optimal easy-to-blend designs. The preconditioned design is then fed to the scheme using cellular automata that have been developed by the authors. The method is applied to the benchmark 18-panel horseshoe blending problem to demonstrate its performance. The computational efficiency of the proposed method makes it especially suited for composite structures with a large number of design regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=blending" title=" blending"> blending</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=lamination%20parameters" title=" lamination parameters"> lamination parameters</a> </p> <a href="https://publications.waset.org/abstracts/76009/computationally-efficient-stacking-sequence-blending-for-composite-structures-with-a-large-number-of-design-regions-using-cellular-automata" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76009.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">227</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> Study of Interaction between Recycled Asphalt Pavement (RAP) Material and Virgin Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Bharath">G.

When RAP is mixed with virgin aggregates in the presence of fresh binder there will be partial blending in a hot mix asphalt mixture. A recent approach used by some researchers for studying the degree of blending of RAP binder with virgin binder has been adopted in this study. Dense Bituminous Macadam mix of Ministry of Road Transport of India with a nominal maximum aggregate size of 19 mm was studied. Two proportions of RAP-20% and 35% and two types of virgin binders – viscosity grade VG10 and VG30 were considered. Design binder contents were determined for all the four types of mixes (two RAP contents and two virgin binders) as per Marshall mix design procedure. The degree of blending of RAP and virgin binders was evaluated in terms of the complex modulus of the binder. Laboratory test results showed that with an increase in RAP content, the degree of blending decreases. Better blending was observed for softer grade binder (VG10). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blending" title="blending">blending</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20modulus" title=" complex modulus"> complex modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20asphalt%20pavement" title=" recycled asphalt pavement"> recycled asphalt pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=virgin%20binder" title=" virgin binder"> virgin binder</a> </p> <a href="https://publications.waset.org/abstracts/24171/study-of-interaction-between-recycled-asphalt-pavement-rap-material-and-virgin-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24171.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">432</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> Compounding and Blending in English and Hausa Languages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Maimota">Maryam Maimota</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Words are the basic building blocks of a language. In everyday usage of a language, words are used and new words are formed and reformed in order to contain and accommodate all entities, phenomena, qualities and every aspect of the entire human life. This research study seeks to examine and compare some of the word formation processes and how they are used in forming new words in English and Hausa languages. The study focuses its main attention on blending and compounding as word formation processes and how the processes are used adequately in the formation of words in both English and Hausa languages. The research aims to find out, how compounding and blending are used, as processes of word formation in these two languages. And also, to investigate the word formation processes involved in compounding and blending in these languages, and the nature of words that are formed. Therefore, the research tries to find the answers to the following research questions; What types of compound and blended forms are found and how they are formed in the English and Hausa languages? How these compounded and blended forms functioned in both English and Hausa languages in different context such as in phrases and sentences structures? Findings of the study reveal that, there exist new kind of words formed in Hausa and English language under blending, which previous findings did not either reveal or explain in detail. Similarly, there are a lot of similarities found in the way these blends and compounds forms in the two languages, however, the data available shows that, blends in the Hausa language are more, when compared to the blends in English. The data of this study will be gathered based on discourse found in newspaper, articles, novels, and written literature of the Hausa and English languages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blending" title="blending">blending</a>, <a href="https://publications.waset.org/abstracts/search?q=compounding" title=" compounding"> compounding</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=word%20formation" title=" word formation"> word formation</a> </p> <a href="https://publications.waset.org/abstracts/52244/compounding-and-blending-in-english-and-hausa-languages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52244.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">381</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> Reactive Blending of Thermoplastic Starch, Ethylene-1-Butene Rubber, and Chitosan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kittisak%20Jantanasakulwong">Kittisak Jantanasakulwong</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshiaki%20Ougizawa"> Toshiaki Ougizawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thermoplastic starch (TPS) was prepared by melt-blending of cassava starch with glycerol (70/30 wt%/wt%) at 130 ◦C for 10 min.

Thus, this study tries to analyze and investigate how the conceptual metonymies in Johnson's speech about coronavirus are constructed. This study aims at: Identifying how are metonymies relevant to understand the messages in Boris Johnson speeches and to find out how can conceptual blending theory help people to understand the messages in the political speech about COVID-19. Lastly, it tries to Point out the kinds of integration networks are common in political speech. The study is based on the hypotheses that conceptual blending theory is a powerful tool for investigating the intended messages in Johnson's speech and there are different processes of blending networks and conceptual mapping that enable the listeners to identify the messages in political speech. This study presents a qualitative and quantitative analysis of four speeches about COVID-19; they are said by Boris Johnson. The selected data have been tackled from the cognitive-semantic perspective by adopting Conceptual Blending Theory as a model for the analysis. It concludes that CBT is applicable to the analysis of metonymies in political discourse. Its mechanisms enable listeners to analyze and understand these speeches. Also the listener can identify and understand the hidden messages in Biden and Johnson's discourse about COVID-19 by using different conceptual networks. Finally, it is concluded that the double scope networks are the most common types of blending of metonymies in the political speech. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive" title="cognitive">cognitive</a>, <a href="https://publications.waset.org/abstracts/search?q=semantics" title=" semantics"> semantics</a>, <a href="https://publications.waset.org/abstracts/search?q=conceptual" title=" conceptual"> conceptual</a>, <a href="https://publications.waset.org/abstracts/search?q=metonymical" title=" metonymical"> metonymical</a>, <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title=" Covid-19"> Covid-19</a> </p> <a href="https://publications.waset.org/abstracts/157124/cognitive-semantics-study-of-conceptual-and-metonymical-expressions-in-johnsons-speeches-about-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157124.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">128</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> Meaning Interpretation of Persian Noun-Noun Compounds: A Conceptual Blending Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahareh%20Yousefian">Bahareh Yousefian</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurel%20Smith%20Stvan"> Laurel Smith Stvan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Linguistic structures have two facades: form and meaning. These structures could have either literal meaning or figurative meaning (although it could also depend on the context in which that structure appears). The literal meaning is understandable more easily, but for the figurative meaning, a word or concept is understood from a different word or concept. In linguistic structures with a figurative meaning, it’s more difficult to relate their forms to the meanings than structures with literal meaning. In these cases, the relationship between form and figurative meaning could be studied from different perspectives. Various linguists have been curious about what happens in someone’s mind to understand figurative meaning through the forms; they have used different perspectives and theories to explain this process. It has been studied through cognitive linguistics as well, in which mind and mental activities are really important. In this viewpoint, meaning (in other words, conceptualization) is considered a mental process. In this descriptive-analytic study, 20 Persian compound nouns with figurative meanings have been collected from the Persian-language Moeen Encyclopedic Dictionary and other sources. Examples include [“Sofreh Xaneh”] (traditional restaurant) and [“Dast Yar”] (Assistant). These were studied in a cognitive semantics framework using “Conceptual Blending Theory” which hasn’t been tested on Persian compound nouns before. It was noted that “Conceptual Blending Theory” could lead to the process of understanding the figurative meanings of Persian compound nouns. Many cognitive linguists believe that “Conceptual Blending” is not only a linguistic theory but it’s also a basic human cognitive ability that plays important roles in thought, imagination, and even everyday life as well (though unconsciously). The ability to use mental spaces and conceptual blending (which is exclusive to humankind) is such a basic but unconscious ability that we are unaware of its existence and importance. What differentiates Conceptual Blending Theory from other ways of understanding figurative meaning, are arising new semantic aspects (emergent structure) that lead to a more comprehensive and precise meaning. In this study, it was found that Conceptual Blending Theory could explain reaching the figurative meanings of Persian compound nouns from their forms, such as [talkative for compound word of “Bolbol + Zabani” (nightingale + tongue)] and [wage for compound word of “Dast + Ranj” (hand + suffering)]. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20linguistics" title="cognitive linguistics">cognitive linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=conceptual%20blending" title=" conceptual blending"> conceptual blending</a>, <a href="https://publications.waset.org/abstracts/search?q=figurative%20meaning" title=" figurative meaning"> figurative meaning</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20compound%20nouns" title=" Persian compound nouns"> Persian compound nouns</a> </p> <a href="https://publications.waset.org/abstracts/172903/meaning-interpretation-of-persian-noun-noun-compounds-a-conceptual-blending-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172903.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">77</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> Blending Effects on Crude Oil Stability: An Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muheddin%20Hamza">Muheddin Hamza</a>, <a href="https://publications.waset.org/abstracts/search?q=Entisar%20Etter"> Entisar Etter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is a part of investigating the possibility of blending two crude oils obtained from Libyan oil fields, namely crude oil (A) and crude oil (B) with different ratios, prior to blending the crude oils have to be compatible in order to avoid phase out and precipitation of asphaltene from the bulk of crude. The physical properties of both crudes such as density, viscosity, pour point and sulphur content were measured according to (ASTM) method. To examine the stability of both crudes and their blends, the oil compatibility model using microscopic, colloidal instability index (CII) using SARA analysis and asphaltene stabilization test using Turbiscan tests were conducted in the Libyan Petroleum Institute laboratories. Compatibility tests were carried out with both crude oils, the insolubility number (IN), and the solubility blending number (SBN), for both crude oils and their blends were calculated. The criteria for compatibility of any blend is that the volume average solubility blending number (SBN) is greater than the insolubility number (IN) of any component in the blend, the results indicated that both crudes were compatible. To support the results of compatibility tests the SARA analysis was done for the fractional determination of (saturates, aromatics, resins and asphaltenes) content. From this result, the colloidal Instability index (CII) and resin to asphaltenes ratio (R/A) were calculated for crudes and their blends. The results show that crude oil (B) which has higher (R/A) and lower (CII) is more stable than crude oil (A) and as the ratio of crude (B) increases in the blend the (CII) and (R/A) were improved, and the blends becomes more stable. Asphaltene stabilization test was also conducted for the crudes and their blends using Turbiscan MA200 according to the standard test method ASTM D7061-04, the Turbiscan shows that the crude (B) is more stable than crude (A) which shows a fair tendency. The (CII) and (R/A) were compared with the solubility number (SBN) for each crude and the blends along with Turbiscan results. The solubility blending number (SBN) of the crudes and their blends show that the crudes are compatible, also by comparing (R/A) and (SBN) values of the blends, it can be seen that they are complements of each other. All the experimental results show that the blends of both crudes are more stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphaltene" title="asphaltene">asphaltene</a>, <a href="https://publications.waset.org/abstracts/search?q=crude%20oil" title=" crude oil"> crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=compatibility" title=" compatibility"> compatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20blends" title=" oil blends"> oil blends</a>, <a href="https://publications.waset.org/abstracts/search?q=resin" title=" resin"> resin</a>, <a href="https://publications.waset.org/abstracts/search?q=SARA" title=" SARA"> SARA</a> </p> <a href="https://publications.waset.org/abstracts/68752/blending-effects-on-crude-oil-stability-an-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68752.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">511</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> Multiresolution Mesh Blending for Surface Detail Reconstruction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Honorio%20Salmeron%20Valdivieso">Honorio Salmeron Valdivieso</a>, <a href="https://publications.waset.org/abstracts/search?q=Andy%20Keane"> Andy Keane</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Toal"> David Toal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the area of mechanical reverse engineering, processes often encounter difficulties capturing small, highly localized surface information. This could be the case if a physical turbine was 3D scanned for lifecycle management or robust design purposes, with interest on eroded areas or scratched coating. The limitation partly is due to insufficient automated frameworks for handling -localized - surface information during the reverse engineering pipeline. We have developed a tool for blending surface patches with arbitrary irregularities into a base body (e.g. a CAD solid). The approach aims to transfer small surface features while preserving their shape and relative placement by using a multi-resolution scheme and rigid deformations. Automating this process enables the inclusion of outsourced surface information in CAD models, including samples prepared in mesh handling software, or raw scan information discarded in the early stages of reverse engineering reconstruction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=application%20lifecycle%20management" title="application lifecycle management">application lifecycle management</a>, <a href="https://publications.waset.org/abstracts/search?q=multiresolution%20deformation" title=" multiresolution deformation"> multiresolution deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20engineering" title=" reverse engineering"> reverse engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20design" title=" robust design"> robust design</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20blending" title=" surface blending"> surface blending</a> </p> <a href="https://publications.waset.org/abstracts/137875/multiresolution-mesh-blending-for-surface-detail-reconstruction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137875.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">139</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">189</span> Conjunctive Use of Shallow Groundwater for Irrigation Purpose: The Case of Wonji Shoa Sugar Estate, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Megersa%20Olumana%20Dinka">Megersa Olumana Dinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Kassahun%20Birhanu%20Tadesse"> Kassahun Birhanu Tadesse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Irrigation suitability of shallow groundwater (SGW) was investigated by taking thirty groundwater samples from piezometers and hand-dug wells in Wonji Shoa Sugar Estate (WSSE) (Ethiopia). Many physicochemical parameters (Mg²⁺, Na⁺, Ca²⁺, K⁺, CO₃-, SO4²⁻, HCO₃⁻, Cl⁻, TH, EC, TDS and pH) were analyzed following standard procedures. Different irrigation indices (MAR, SSP, SAR, RSC, KR, and PI) were also used for SGW suitability assessment. If all SGW are blended and used for irrigation, the salinity problem would be slight to moderate, and 100% of potential sugarcane yield could be obtained. The infiltration and sodium ion toxicity problems of the blended water would be none to moderate, and slight to moderate, respectively. As sugarcane is semi-tolerant to sodium toxicity, no significant sodium toxicity problem would be expected from the use of blended water. Blending SGW would also reduce each chloride and boron ion toxicity to none. In general, the rating of SGW was good to excellent for irrigation in terms of average EC (salinity), and excellent in terms of average SAR (infiltration). The SGW of the WSSE was categorized under C3S1 (high salinity and low sodium hazard). In conclusion, the conjunctive use of groundwater for irrigation would help to reduce the potential effect of waterlogging and salinization and their associated problems on soil and sugarcane production and productivity. However, a high value of SSP and RSC indicate a high possibility of infiltration problem. Hence, it is advisable to use the SGW for irrigation after blending with surface water. In this case, the optimum blending ratio of the surface to SGW sources has to be determined for sustainable sugarcane productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blending" title="blending">blending</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration" title=" infiltration"> infiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=sodicity" title=" sodicity"> sodicity</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane" title=" sugarcane"> sugarcane</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a> </p> <a href="https://publications.waset.org/abstracts/81841/conjunctive-use-of-shallow-groundwater-for-irrigation-purpose-the-case-of-wonji-shoa-sugar-estate-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81841.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">382</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">188</span> Drivers and Barriers of Asphalt Rubber in Sweden</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raheb%20Mirzanamadi">Raheb Mirzanamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Patr%C3%ADcio"> João Patrício</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Asphalt rubber (AR) was initially developed in Sweden in the 1960s by replacing crumb rubber (CR) as aggregates in asphalt pavement. The AR produced by this method had better mechanical properties than conventional asphalt pavement but was very expensive. Since then, different technologies and methods have been developed to use CR in asphalt pavements, including blending CR with bitumen at a high temperature in the mixture, called the wet method, and blending CR with bitumen in the refinery, called the terminal blending method. In 2006, the wet method was imported from the USA to Sweden to evaluate the potential of using AR on Swedish roads. 154 km AR roads were constructed by the wet method in Sweden. The evaluation showed that the AR had, in most cases, better mechanical performance than conventional asphalt pavements. However, the terrible smoke and smell led the Swedish Transport Administration (STA) to stop using AR in Sweden. Today, there are few focuses on AR, despite its good mechanical properties and environmental aspects. Hence, there is a need to study the drives and barriers of using AR mixture in Sweden. The aims of this paper are: (i) to study drivers and barriers of using AR pavements in Sweden and (ii) to discover knowledge gaps for further research in this area. The study was done using a literature review and completed by interviews with experts, including three researchers from Swedish National Road and Transport Research Institute (VTI) and two experts from STA. The results showed that AR can be an alternative not only for conventional asphalt pavement but also for polymer modified asphalt (PMA) due to the same mechanical properties but the lower cost for production. New technologies such as terminal blending and using warm mix asphalt (WMA) methods can lead to reducing the energy and temperature during production processes. From this study, it is found that there is not enough experience and knowledge about AR in Sweden, and more research is needed, including the lifespan of AR, mechanical properties of AR using new technologies, and the impact of AR on spreading and leaching substances into nature. More studies can lead to standardization of using AR in Sweden, a potential solution for the use of end-of-life tyres, with better mechanical properties and lower costs, in comparison with conventional asphalt pavements and PMA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt%20rubber" title="asphalt rubber">asphalt rubber</a>, <a href="https://publications.waset.org/abstracts/search?q=crumb%20rubber" title=" crumb rubber"> crumb rubber</a>, <a href="https://publications.waset.org/abstracts/search?q=terminal%20blending%20method" title=" terminal blending method"> terminal blending method</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20method" title=" wet method"> wet method</a> </p> <a href="https://publications.waset.org/abstracts/147213/drivers-and-barriers-of-asphalt-rubber-in-sweden" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147213.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">81</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">187</span> Effect of Minerals in Middlings on the Reactivity of Gasification-Coke by Blending a Large Proportion of Long Flame Coal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianjun%20Wu">Jianjun Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Fanhui%20Guo"> Fanhui Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yixin%20Zhang"> Yixin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, gasification-coke were produced by blending the middlings (MC), and coking coal (CC) and a large proportion of long flame coal (Shenfu coal, SC), the effects of blending ratio were investigated.

Structure characteristics of partially gasification-coke such as surface area and porosity were determined using the N₂ adsorption and mercury porosimetry. Experimental data of gasification-coke was dominated by the TGA results provided trend, reactivity differences between gasification-cokes are discussed in terms of structure characteristic, crystallinity, and alkali index (AI). The first-order reaction equation was suitable for the gasification reaction kinetics of CO₂ atmosphere which was represented by the volumetric reaction model with linear correlation coefficient above 0.985. The differences in the microporous structure of gasification-coke and catalysis caused by the minerals in parent coals were supposed to be the main factors which affect its reactivity.

De Boer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A method is introduced for the coupled skin-rib optimization of a wing box where mass minimization is the objective and local buckling is the constraint. The structure is made of composite materials where continuity of plies in multiple adjacent panels (blending) has to be satisfied. Blending guarantees the manufacturability of the structure; however, it is a highly challenging constraint to treat and has been under debate in recent research in the same area. To fulfill design guidelines with respect to symmetry, balance, contiguity, disorientation and percentage rule of the layup, a reference for the stacking sequences (stacking sequence table or SST) is generated first. Then, an innovative fully gradient-based optimization approach in relation to a specific SST is introduced to obtain the optimum thickness distribution all over the structure while blending is fulfilled. The proposed optimization approach aims to turn the discrete optimization problem associated with the integer number of plies into a continuous one. As a result of a wing box deflection, a rib is subjected to load values which vary nonlinearly with the amount of deflection. The bending stiffness of a skin affects the wing box deflection and thus affects the load applied to a rib. This indicates the necessity of a coupled skin-rib optimization approach for a more realistic optimized design. The proposed method is examined with the optimization of the layup of a composite stiffened skin and rib of a wing torsion box subjected to in-plane normal and shear loads. Results show that the method can successfully prescribe a valid design with a significantly cheap computation cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blending" title="blending">blending</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling%20optimization" title=" buckling optimization"> buckling optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20panels" title=" composite panels"> composite panels</a>, <a href="https://publications.waset.org/abstracts/search?q=wing%20torsion%20box" title=" wing torsion box"> wing torsion box</a> </p> <a href="https://publications.waset.org/abstracts/68057/a-coupled-stiffened-skin-rib-fully-gradient-based-optimization-approach-for-a-wing-box-made-of-blended-composite-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68057.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">409</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">185</span> Impact of Material Chemistry and Morphology on Attrition Behavior of Excipients during Blending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Sharath%20Kulkarni">Sri Sharath Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Pauline%20Janssen"> Pauline Janssen</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Berardi"> Alberto Berardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bastiaan%20Dickhoff"> Bastiaan Dickhoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20van%20Gessel"> Sander van Gessel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blending is a common process in the production of pharmaceutical dosage forms where the high shear is used to obtain a homogenous dosage. The shear required can lead to uncontrolled attrition of excipients and affect API’s. This has an impact on the performance of the formulation as this can alter the structure of the mixture. Therefore, it is important to understand the driving mechanisms for attrition. The aim of this study was to increase the fundamental understanding of the attrition behavior of excipients. Attrition behavior of the excipients was evaluated using a high shear blender (Procept Form-8, Zele, Belgium). Twelve pure excipients are tested, with morphologies varying from crystalline (sieved), granulated to spray dried (round to fibrous). Furthermore, materials include lactose, microcrystalline cellulose (MCC), di-calcium phosphate (DCP), and mannitol. The rotational speed of the blender was set at 1370 rpm to have the highest shear with a Froude (Fr) number 9. Varying blending times of 2-10 min were used. Subsequently, after blending, the excipients were analyzed for changes in particle size distribution (PSD). This was determined (n = 3) by dry laser diffraction (Helos/KR, Sympatec, Germany). Attrition was found to be a surface phenomenon which occurs in the first minutes of the high shear blending process. An increase of blending time above 2 mins showed no change in particle size distribution. Material chemistry was identified as a key driver for differences in the attrition behavior between different excipients. This is mainly related to the proneness to fragmentation, which is known to be higher for materials such as DCP and mannitol compared to lactose and MCC. Secondly, morphology also was identified as a driver of the degree of attrition. Granular products consisting of irregular surfaces showed the highest reduction in particle size. This is due to the weak solid bonds created between the primary particles during the granulation process. Granular DCP and mannitol show a reduction of 80-90% in x10(µm) compared to a 20-30% drop for granular lactose (monohydrate and anhydrous). Apart from the granular lactose, all the remaining morphologies of lactose (spray dried-round, sieved-tomahawk, milled) show little change in particle size. Similar observations have been made for spray-dried fibrous MCC. All these morphologies have little irregular or sharp surfaces and thereby are less prone to fragmentation. Therefore, products containing brittle materials such as mannitol and DCP are more prone to fragmentation when exposed to shear. Granular products with irregular surfaces lead to an increase in attrition. While spherical, crystalline, or fibrous morphologies show reduced impact during high shear blending. These changes in size will affect the functionality attributes of the formulation, such as flow, API homogeneity, tableting, formation of dust, etc. Hence it is important for formulators to fully understand the excipients to make the right choices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attrition" title="attrition">attrition</a>, <a href="https://publications.waset.org/abstracts/search?q=blending" title=" blending"> blending</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20manufacturing" title=" continuous manufacturing"> continuous manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=excipients" title=" excipients"> excipients</a>, <a href="https://publications.waset.org/abstracts/search?q=lactose" title=" lactose"> lactose</a>, <a href="https://publications.waset.org/abstracts/search?q=microcrystalline%20cellulose" title=" microcrystalline cellulose"> microcrystalline cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=shear" title=" shear"> shear</a> </p> <a href="https://publications.waset.org/abstracts/147446/impact-of-material-chemistry-and-morphology-on-attrition-behavior-of-excipients-during-blending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147446.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">111</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">184</span> Investigating the Physical Properties of Polycaprolactone/Eucomis autumnalis Nanocellulose Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dolly%20Selikane">Dolly Selikane</a>, <a href="https://publications.waset.org/abstracts/search?q=Thandi%20Gumede"> Thandi Gumede</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among the commonly studied organic fillers for polycaprolactone (PCL), cellulose is the most promising. It is available in various particle sizes and sources, providing numerous options for finding a suitable match for PCL matrices. In this study, cellulose was extracted from the leaves of E. autumnalis to create a PCL/nanocellulose composite through melt blending. The prepared nanocellulose was blended with PCL at a weight ratio of 97/3, and the resulting composite was characterized by its thermal and mechanical properties. The results showed that the addition of nanocellulose to PCL improved its mechanical properties, with a maximum increase of 29% in tensile strength and 31% in Young's modulus. The SEM analysis confirmed the successful blending of PCL and nanocellulose.

The experimental analysis is carried out at different load conditions to analyze the impact of the blending ratio on the performance and emission parameters. When the blending proportion of biodiesel is increased, then the highest pressure reduces due to the fall in the calorific value of the blended mixture.

Modular housing construction has become more efficient and cost-effective than traditional building methods and is becoming increasingly popular for commercial, industrial, and residential projects. Effective project management and logistics will be imperative in the future speed and cost of modular construction housing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology%20blending" title="technology blending">technology blending</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=housing" title=" housing"> housing</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a> </p> <a href="https://publications.waset.org/abstracts/164259/technology-blending-as-an-innovative-construction-mechanism-in-the-global-south" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164259.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">87</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">181</span> Co-Hydrothermal Gasification of Microalgae Biomass and Solid Biofuel for Biogas Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Fozer">Daniel Fozer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Limiting global warming to 1.5°C to the pre-industrial levels urges the application of efficient and sustainable carbon dioxide removal (CDR) technologies. Microalgae based biorefineries offer scalable solutions for the biofixation of CO2, where the produced biomass can be transformed into value added products by applying thermochemical processes. In this paper we report on the utilization of hydrochar as a blending component in hydrothermal gasification (HTG) process. The effects of blending ratio and hydrochar quality were investigated on the biogas yield and and composition. It is found that co-gasifying the hydrochar and the algae biomass can increase significantly the total gas yield and influence the biogas (H2, CH4, CO2, CO, C2H4, C2H6) composition. It is determined that the carbon conversion ratio, hydrogen and methane selectivity can be increased by influencing the fuel ratio of hydrochar via hydrothermal carbonization. In conclusion, it is found that increasing the synergy between hydrothermal technologies result in elevated conversion efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=CDR" title=" CDR"> CDR</a>, <a href="https://publications.waset.org/abstracts/search?q=Co-HTG" title=" Co-HTG"> Co-HTG</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrochar" title=" hydrochar"> hydrochar</a>, <a href="https://publications.waset.org/abstracts/search?q=microalgae" title=" microalgae"> microalgae</a> </p> <a href="https://publications.waset.org/abstracts/120057/co-hydrothermal-gasification-of-microalgae-biomass-and-solid-biofuel-for-biogas-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120057.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">149</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">180</span> Crosssampler: A Digital Convolution Cross Synthesis Instrument</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jimmy%20Eadie">Jimmy Eadie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Convolutional Cross Synthesis (CCS) has emerged as a powerful technique for blending input signals to create hybrid sounds. It has significantly expanded the horizons of digital signal processing, enabling artists to explore audio effects. However, the conventional applications of CCS primarily revolve around reverberation and room simulation rather than being utilized as a creative synthesis method. In this paper, we present the design of a digital instrument called CrossSampler that harnesses a parametric approach to convolution cross-synthesis, which involves using adjustable parameters to control the blending of audio signals through convolution. These parameters allow for customization of the resulting sound, offering greater creative control and flexibility. It enables users to shape the output by manipulating factors such as duration, intensity, and spectral characteristics. This approach facilitates experimentation and exploration in sound design and opens new sonic possibilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convolution" title="convolution">convolution</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=sampling" title=" sampling"> sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20instrument" title=" virtual instrument"> virtual instrument</a> </p> <a href="https://publications.waset.org/abstracts/183096/crosssampler-a-digital-convolution-cross-synthesis-instrument" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183096.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">64</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">179</span> A Blending Analysis of Metaphors and Metonymies Used to Depict the Deal of the Century by Jordanian Cartoonists</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aseel%20Zibin">Aseel Zibin</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Rahman%20Altakhaineh"> Abdel Rahman Altakhaineh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study analyses 30 cartoons depicting THE DEAL OF THE CENTURY as envisaged by two Jordanian cartoonists, namely, EmadHajjaj and Osama Hajjaj. Conceptual Blending Theory (CBT) and Multimodal Metaphor Theory (MMT) are adopted as a theoretical framework to interpret the metaphors and metonymies used in the target cartoons. The results reveal that the target domain THE DEAL OF THE CENTURY was conceptualized mainly through layered metaphors that have metonymic basis and event metaphors\allegories. Specifically, 6 groups were identified: OBJECT or a situation involving OBJECTS, situations involving HUMANS\HYBRIDS of HUMANS and OBJECTS, an ANIMAL OR situation involving an ANIMAL, hybrids of WEAPONS and humans, and event metaphors used to build a story\allegory. The target domain was also depicted via event metaphors used to build a story; some of which are embedded in the Jordanian culture, while others could be perceivable cross-culturally. The results also demonstrate that the most widely used configurations to construe the metaphors was the pictorial source–verbal target in line with Lan and Zuo (2016); the motivation was probably the greater conceptual density and concreteness of visual representation since the target is better captured verbally because of its abstractness. The use of cross-modal mappings of this type was attributed to the abstractness of the target domain, THE DEAL OF THE CENTURY, which makes it more construable via verbal cues rather than visual ones. In contrast, the source domains used were mainly concrete and thus perceivable pictorially rather than verbally. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=semiotics" title="semiotics">semiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20semantics" title=" cognitive semantics"> cognitive semantics</a>, <a href="https://publications.waset.org/abstracts/search?q=metaphor" title=" metaphor"> metaphor</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=blending" title=" blending"> blending</a>, <a href="https://publications.waset.org/abstracts/search?q=cartoon" title=" cartoon"> cartoon</a> </p> <a href="https://publications.waset.org/abstracts/157902/a-blending-analysis-of-metaphors-and-metonymies-used-to-depict-the-deal-of-the-century-by-jordanian-cartoonists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157902.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">178</span> Simulation of Optimal Runoff Hydrograph Using Ensemble of Radar Rainfall and Blending of Runoffs Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myungjin%20Lee">Myungjin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Daegun%20Han"> Daegun Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Jongsung%20Kim"> Jongsung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Soojun%20Kim"> Soojun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung%20Soo%20Kim"> Hung Soo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the localized heavy rainfall and typhoons are frequently occurred due to the climate change and the damage is becoming bigger. Therefore, we may need a more accurate prediction of the rainfall and runoff. However, the gauge rainfall has the limited accuracy in space. Radar rainfall is better than gauge rainfall for the explanation of the spatial variability of rainfall but it is mostly underestimated with the uncertainty involved. Therefore, the ensemble of radar rainfall was simulated using error structure to overcome the uncertainty and gauge rainfall. The simulated ensemble was used as the input data of the rainfall-runoff models for obtaining the ensemble of runoff hydrographs. The previous studies discussed about the accuracy of the rainfall-runoff model. Even if the same input data such as rainfall is used for the runoff analysis using the models in the same basin, the models can have different results because of the uncertainty involved in the models. Therefore, we used two models of the SSARR model which is the lumped model, and the Vflo model which is a distributed model and tried to simulate the optimum runoff considering the uncertainty of each rainfall-runoff model. The study basin is located in Han river basin and we obtained one integrated runoff hydrograph which is an optimum runoff hydrograph using the blending methods such as Multi-Model Super Ensemble (MMSE), Simple Model Average (SMA), Mean Square Error (MSE). From this study, we could confirm the accuracy of rainfall and rainfall-runoff model using ensemble scenario and various rainfall-runoff model and we can use this result to study flood control measure due to climate change.

Atwood’s prose seems to be imbued with Canadianisms and neologisms, lexical blends of zoomorphic forms, a kind of meeting-point between two conceptual structures which follow the principles of lexical economy and asyntactic relation. Atwood’s neologisms also attest to the undeniable impact on language exerted by Canada’s aboriginal peoples. This paper aims to track through these references and with the aid of the Eskimo-English dictionary look at the linguistic issues – attitudes to contaminations and hybridisations, questions of lexical blending in literary examples, etc – which they raise. Atwood’s fiction, whose cognitive linguistic strategy employs ‘the virtues of scissors and matches’, always strives to achieve isomorphism between word form and concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atwood" title="Atwood">Atwood</a>, <a href="https://publications.waset.org/abstracts/search?q=Canadianisms" title=" Canadianisms"> Canadianisms</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20science" title=" cognitive science"> cognitive science</a>, <a href="https://publications.waset.org/abstracts/search?q=Eskimo%2FEnglish%20dictionary" title=" Eskimo/English dictionary"> Eskimo/English dictionary</a> </p> <a href="https://publications.waset.org/abstracts/70217/atwoods-canadianisms-and-neologisms-a-cognitive-approach-to-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70217.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">264</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">175</span> The Customization of 3D Last Form Design Based on Weighted Blending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shih-Wen%20Hsiao">Shih-Wen Hsiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chu-Hsuan%20Lee"> Chu-Hsuan Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong-Qi%20Chen"> Rong-Qi Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When it comes to last, it is regarded as the critical foundation of shoe design and development. Not only the last relates to the comfort of shoes wearing but also it aids the production of shoe styling and manufacturing. In order to enhance the efficiency and application of last development, a computer aided methodology for customized last form designs is proposed in this study. The reverse engineering is mainly applied to the process of scanning for the last form. Then the minimum energy is used for the revision of surface continuity, the surface of the last is reconstructed with the feature curves of the scanned last. When the surface of a last is reconstructed, based on the foundation of the proposed last form reconstruction module, the weighted arithmetic mean method is applied to the calculation on the shape morphing which differs from the grading for the control mesh of last, and the algorithm of subdivision is used to create the surface of last mesh, thus the feet-fitting 3D last form of different sizes is generated from its original form feature with functions remained. Finally, the practicability of the proposed methodology is verified through later case studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20last%20design" title="3D last design">3D last design</a>, <a href="https://publications.waset.org/abstracts/search?q=customization" title=" customization"> customization</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20engineering" title=" reverse engineering"> reverse engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=weighted%20morphing" title=" weighted morphing"> weighted morphing</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20blending" title=" shape blending"> shape blending</a> </p> <a href="https://publications.waset.org/abstracts/7580/the-customization-of-3d-last-form-design-based-on-weighted-blending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7580.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">339</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">174</span> Changes in Some Bioactive Content and Antioxidant Capacity of Different Brassica Herbals after Pretreatment and Herbal Infusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evren%20C.%20%20Eroglu">Evren C.

Especially in the production of herbal tea from fresh herbals, it is considered that elapsed time from blending to last product may affect the bioactive properties and antioxidant contents. Herbal infusion is basically prepared by mixing herbs with hot water for 10-20 min. During the brewing of these herbs, it is supposed to be significant decrease in the antioxidant and phenolics content. The first aim of this study was to evaluate the changes of vitamin C (VitC), total phenolic content (TPC) and antioxidant contents (AO) of two brassica varieties (brussel sprouts and white head cabbage) with different holding time after blending. Second aim of this study was to understand the effect of herbal infusion on VitC, TPC and AO contents. In this study, fresh samples were subjected to 0-30 min holding time after blending. Then, samples was immediately taken to -80 °C and freeze drying process was performed. Herbal infusion was performed for 20 minutes. According to results, VitC contents in brussel sprouts was not changed significantly (p=0.12). However, there was a significant decreasing of VitC content in cabbage sample (p=0.034). 20 min of brewing caused a significant decrement in VitC of brussel sprouts by approximately 76% (1071 ppm dw), while decline in cabbage VitC content was 87% (531 ppm dw). AO and TPC values of unprocessed cabbage control sample (13791.87 ppm FeSO4·7H2O eq. dw and 5301.85 ppm gallic acid eq. dw) were higher than brussel sprouts control samples (11571.75 ppm FeSO4·7H2O dw and 5202.76 ppm, respectively). The change in AO and TPC of both brussel sprouts and cabbage samples were not statistically significant at the end of 30 minutes holding time (p=0.24 and p=0.38). After 20 minutes of brewing, AO content in brussel sprouts significantly decreased by 44% (p ˂0.05). Although, the decreasing of AO in white head cabbage was statistically important (p=0.034), decreasing was just 8%. TPC values were found to decrease by 54% in cabbage, while it was 35% in brussel sprouts after herbal infusion. It was observed that 30 min holding time had no statistically important effect on TPC values of both cabbage and brussel sprouts. As a conclusion, herbal infusion has more or less effect on VitC, TPC and AO contents of samples. Therefore, it is important to decrease brewing time. Another result was that there were no significant differences in TPC and AO content of both samples when holding samples 30 min outside after blending. However, this process had significant effect on VitC content of white head cabbage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antioxidant%20content" title="Antioxidant content">Antioxidant content</a>, <a href="https://publications.waset.org/abstracts/search?q=brussel%20sprouts" title=" brussel sprouts"> brussel sprouts</a>, <a href="https://publications.waset.org/abstracts/search?q=herbal%20infusion" title=" herbal infusion"> herbal infusion</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenolic%20content" title=" total phenolic content"> total phenolic content</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20head%20cabbage" title=" white head cabbage"> white head cabbage</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20c" title=" vitamin c"> vitamin c</a> </p> <a href="https://publications.waset.org/abstracts/118982/changes-in-some-bioactive-content-and-antioxidant-capacity-of-different-brassica-herbals-after-pretreatment-and-herbal-infusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118982.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">128</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">173</span> Effect of Bulk Density and Fiber Blend Content of Nonwoven Textiles on Flammability Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Klara%20Masnicova">Klara Masnicova</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiri%20Chaloupek"> Jiri Chaloupek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flammability plays an important role in applications such as thermal and acoustic insulation and other technical nonwoven textiles.

Nonwoven structures made of blends of viscose/oxidized polyacrylonitrile (VS/oxidized PAN fibers and polyethylene terephthalate/oxidized polyacrylonitrile (PET/oxidized PAN) fibers in several bulk densities are evaluated. The VS/oxidized PAN blend is model material. The flammability was studied using a cone calorimeter. Reaction to fire was observed using the small flame test method. Interestingly, the results show some of the blending ratios do not react to the heat in linear response to bulk density.

The industry is characterized by increasing additive usage in base oil blending for longer service life and performance. These additives improve the viscosity of oil, act as detergents, defoamers, antioxidants, and antiwear agents. Since additives play a significant role in base oil blending and subsequent formulations as they are critical materials in improving specification and performance of oils. Herein, we report on the synthesis and characterization of three imidazolium derivatives and their application as antioxidants, detergents and antiwear agents. The molecular structure and characterizations of these ionic liquids were confirmed by elemental analysis, FTIR, X-Ray Diffraction (XRD) and 1HNMR spectroscopy. Thermo gravimetric analysis (TGA), is used to study the degradation and thermal stability of the studied base stock samples. It was found that all the prepared ionic liquids additives have excellent power of dispersion and detergency. The ionic liquids as additives to engine oil reduced the friction (38%) and wear volume (76%) of steel balls. The obtained results show that the ionic liquids have an oxidation inhibitor up to 95%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reused%20lubricating%20oil" title="reused lubricating oil">reused lubricating oil</a>, <a href="https://publications.waset.org/abstracts/search?q=waste" title=" waste"> waste</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum" title=" petroleum"> petroleum</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title=" ionic liquids"> ionic liquids</a> </p> <a href="https://publications.waset.org/abstracts/145781/enhancing-reused-lubricating-oil-performance-using-novel-ionic-liquids-based-on-imidazolium-derivatives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145781.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">138</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">171</span> Regenerated Cotton/Feather Keratin Composite Materials Prepared Using Ionic Liquids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasike%20De%20Silva">Rasike De Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Xungai%20Wang"> Xungai Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nolene%20Byrne"> Nolene Byrne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report on the blending of cotton and duck feather towards developing a new textile fibre. The cotton and duck feather were blended together by dissolving both components in an ionic liquid. Ionic liquids are designer solvents consisting entirely of ions with a melting point below 100˚C. Ionic liquids can be designed to have numerous and varied properties which include the ability to dissolve bio polymers. The dissolution of bio polymers such as cotton or wool generally requires very harsh acid or alkaline conditions and high temperatures. The ionic liquids which can dissolve bio polymers can be considered environmentally benign since they have negligible vapor pressure and can be recycled and reused. We have selected the cellulose dissolving and recyclable ionic liquid 1-allyl-3-methylimidazolium chloride (AMIMCl) as the dissolving and blending solvent for the cotton and duck feather materials. We have casted films and wet spun fibres at varying cotton and duck feather compositions and characterized the material properties of these. We find that the addition of duck feather enhances the elasticity of regenerated cotton. The strain% at breakage of the regenerated film was increased from 4.2% to 11.63% with a 10% duck feather loading, while the corresponding stress at breakage reduced from 54.89 MPa to 47.16 MPa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=textile%20materials" title="textile materials">textile materials</a>, <a href="https://publications.waset.org/abstracts/search?q=bio%20polymers" title=" bio polymers"> bio polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title=" ionic liquids"> ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=duck%20feather" title=" duck feather"> duck feather</a> </p> <a href="https://publications.waset.org/abstracts/11508/regenerated-cottonfeather-keratin-composite-materials-prepared-using-ionic-liquids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11508.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">479</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">170</span> Use Process Ring-Opening Polymerization to Melt Processing of Cellulose Nanowhisker from Coconut Husk Fibers-Filled Polylactide-Based Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imam%20Wierawansyah%20Eltara">Imam Wierawansyah Eltara</a>, <a href="https://publications.waset.org/abstracts/search?q=Iftitah"> Iftitah</a>, <a href="https://publications.waset.org/abstracts/search?q=Agus%20Ismail"> Agus Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, cellulose nanowhiskers (CNW) extracted from coconut husk fibers, were incorporated in polylactide (PLA)-based composites. Prior to the blending, PLA chains were chemically grafted on the surface of CNW to enhance the compatibilization between CNW and the hydrophobic polyester matrix. Ring-opening polymerization of L-lactide was initiated from the hydroxyl groups available at the CNW surface to yield CNW-g-PLA nanohybrids. PLA-based nanocomposites were prepared by melt blending to ensure a green concept of the study thereby limiting the use of organic solvents. The influence of PLA-grafted cellulose nanoparticles on the mechanical and thermal properties of the ensuing nanocomposites was deeply investigated. The thermal behavior and mechanical properties of the nanocomposites were determined using differential scanning calorimetry (DSC) and dynamical mechanical and thermal analysis (DMTA), respectively. In theory, evidenced that the chemical grafting of CNW enhances their compatibility with the polymeric matrix and thus improves the final properties of the nanocomposites. Large modification of the crystalline properties such as the crystallization half-time was evidenced according to the nature of the PLA matrix and the content of nanofillers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose%20nanowhiskers" title="cellulose nanowhiskers">cellulose nanowhiskers</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=coconut%20husk%20fiber" title=" coconut husk fiber"> coconut husk fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=ring%20opening%20polymerization" title=" ring opening polymerization"> ring opening polymerization</a> </p> <a href="https://publications.waset.org/abstracts/43287/use-process-ring-opening-polymerization-to-melt-processing-of-cellulose-nanowhisker-from-coconut-husk-fibers-filled-polylactide-based-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43287.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">317</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">169</span> Biodiesel Production from Broiler Chicken Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Abraham">John Abraham</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Saravana%20Kumar"> Ramesh Saravana Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Francis"> Francis</a>, <a href="https://publications.waset.org/abstracts/search?q=Xavier"> Xavier</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Mathew"> Deepak Mathew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Broiler slaughter waste has become a major source of pollution throughout the world. Utilization of broiler slaughter waste by dry rendering process produced Rendered Chicken Oil (RCO) a cheap raw material for biodiesel production and Carcass Meal a feed ingredient for pets and fishes. Conversion of RCO into biodiesel may open new vistas for generating wealth from waste besides controlling the major havoc of environmental pollution. A two-step process to convert RCO to good quality Biodiesel was invented. Acid catalysed esterification of FFA followed by base catalysed transesterification of triglycerides was carried out after meticulously standardising the methanol molar ratio, catalyst concentration, reaction temperature and reaction time to obtain the maximum biodiesel yield of 97.62% and lowest glycerol yield of 6.96%. RCO biodiesel blended was tested in a Mahindra Scorpio CRDI engine. The results revealed that the blending of commercial diesel with 20% RCO biodiesel lead to less engine wear, a quieter engine and better fuel economy. The better lubricating qualities of RCO B20 prevented over heating of engine, which prolongs the engine life. The blending of biodiesel at 20% to commercial diesel can reduce the import of costly crude oil and simultaneously, substantially reduce the engine emissions as proved by significantly lower smoke levels, thus mitigating climatic changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broiler%20waste" title="broiler waste">broiler
