Agronomic, genetic, and climatic works have still found a weak correlation between temperature and frost damage. One possibility that has not been explored within the Australian cropping system is whether ice nucleation active bacteria (INB) either present in situ on crop residue or introduced by rainfall could be responsible for the increased sensitivity of cereal plants to frost at different stages of development. This study investigated upper and lower leaf canopy, stubble, and soil as a potential site of ice nucleation activity (INA) and tracked the changes in INA during the plant development. We found that older leaves of wheat are the primary sites of ice nucleation (-4.7 to -6.3°C) followed by stubble (-5.7 to -6.7°C) which increases the risk of frost damage during heading and flowering (the most susceptible stages). However, healthy and green upper canopy leaves (flag and flag-2) and the soil have lower INA (< -11°C) during the frost-sensitive stage of wheat. We anticipate the higher INA on the stubble and older leaves to be due to the presence of biologically active ice-nucleating bacteria (INB), known to cause frost injury to sensitive plants at -5°C. Stubble retained or applied during the growing season further exacerbates additional frost risk by potentially increasing the INB load. The implications of the result for stubble and frost risk management in a frost-prone landscape will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frost" title="frost">frost</a>, <a href="https://publications.waset.org/abstracts/search?q=ice-nucleation-activity" title=" ice-nucleation-activity"> ice-nucleation-activity</a>, <a href="https://publications.waset.org/abstracts/search?q=stubble" title=" stubble"> stubble</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat" title=" wheat"> wheat</a> </p> <a href="https://publications.waset.org/abstracts/136115/stubble-and-senesced-leaves-are-the-primary-sites-of-ice-nucleation-activity-in-wheat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136115.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">135</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">144</span> Numerical Simulations of Frost Heave Using COMSOL Multiphysics Software in Unsaturated Freezing Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Soltanpour">Sara Soltanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Adolfo%20Foriero"> Adolfo Foriero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Frost heave is arguably the most problematic adverse phenomenon in cold region areas. Frost heave is a complex process that depends on heat and water transfer. These coupled physical fields generate considerable heave stresses as well as deformations.

Particular attention to the frost heave and temperature distribution, as well as the water migrating during soil freezing, is assessed.

The evolution of pipe strain with pressure in the scope of maximum allowable operation pressure (MAOP) is investigated by both strain gauge and X-ray methods.

It subjects the literary piece into a qualitative analysis using the critical theory of mimesis. In effect, this study is proposed to find out and shed light on the mimetic feature of the poem’s textuality. Generally, it aims to analyze the poem’s deeper meaning in the context of the reality of life from birth to death. For the most part, this critical analysis discerns, investigates, and highlights the features which present the imitation of life in detail and from a deeper view. Based on the result of analysis, it shows that Frost has portrayed the cycle of life from birth to midst life as about proving oneself to others as far as achievements and accomplishments are concerned; secondly, at some point of one’s life, successes and achievements are just one’s perfect signature of living. As Frost discloses his poem, his message of the reality of life from birth to death is clear enough, that nothing is going to last forever. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nothing%20Gold%20Can%20Stay" title="Nothing Gold Can Stay">Nothing Gold Can Stay</a>, <a href="https://publications.waset.org/abstracts/search?q=mimesis" title=" mimesis"> mimesis</a>, <a href="https://publications.waset.org/abstracts/search?q=birth" title=" birth"> birth</a>, <a href="https://publications.waset.org/abstracts/search?q=death" title=" death"> death</a> </p> <a href="https://publications.waset.org/abstracts/77123/a-mimetic-textuality-in-robert-frosts-nothing-gold-can-stay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77123.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">471</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">140</span> Spatio-Temporal Variability and Trends in Frost-Free Season Parameters in Finland: Influence of Climate Teleconnections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Irannezhad">Masoud Irannezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirpa%20Rasmus"> Sirpa Rasmus</a>, <a href="https://publications.waset.org/abstracts/search?q=Saghar%20Ahmadian"> Saghar Ahmadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Deliang%20Chen"> Deliang Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bjorn%20Klove"> Bjorn Klove</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Variability and changes in thermal conditions play a crucial role in functioning of human society, particularly over cold climate regions like Finland. Accordingly, the frost-free season (FFS) parameters in terms of start (FFSS), end (FFSE) and length (FFSL) have substantial effects not only on natural environment (e.g. flora and fauna), but also on human requirements (e.g. agriculture, forestry and energy generation). Applying the 0°C threshold of minimum temperature (Tmin), the FFS was defined as the period between the last spring frost as FFSS and the first fall frost as FFSE. For this study, gridded (10 x 10 km2) daily minimum temperature datasets throughout Finland during 1961-2011 was used to investigate recent spatio-temporal variations and trends in frost-free season (FFS) parameters and their relationships with the well-known large-scale climate teleconnections (CTs). The FFS in Finland naturally increases from north (~60 days) to south (~190 days), in association with earlier FFSS (~24 April) and later FFSE (~30 October). Statistically significant (p<0.05) trends in FFSL were all positive (increasing) ranged between 0 and 13.5 (days/decade) and mainly observed in the east, upper west, centre and upper north of Finland. Such lengthening trends in FFS were attributable to both earlier FFSS and later FFSE mostly over central and upper northern Finland, while only to later FFSE in eastern and upper western parts. Variations in both FFSL and FFSS were significantly associated with the Polar (POL) pattern over northern Finland, while with the East Atlantic (EA) pattern over eastern and upper western areas. However, the POL and Scandinavia (SCA) patterns were most influential CTs for FFSE variability over northern Finland. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20teleconnections" title="climate teleconnections">climate teleconnections</a>, <a href="https://publications.waset.org/abstracts/search?q=Finland" title=" Finland"> Finland</a>, <a href="https://publications.waset.org/abstracts/search?q=frost-free%20season" title=" frost-free season"> frost-free season</a>, <a href="https://publications.waset.org/abstracts/search?q=trend%20analysis" title=" trend analysis"> trend analysis</a> </p> <a href="https://publications.waset.org/abstracts/78643/spatio-temporal-variability-and-trends-in-frost-free-season-parameters-in-finland-influence-of-climate-teleconnections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78643.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Preparation and Characterization of Road Base Material Based on Kazakhstan Production Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20K.%20Kaidarova">K.

The solution to this problem can be achieved by replacing traditional building materials with industrial waste, which in their chemical and mineralogical composition are close to natural raw materials and can partially or completely replace some natural binding materials in road construction. In this regard, the purpose of this study is to develop building materials based on the red sludge of the Pavlodar aluminum plant, blast furnace slag of the Karaganda Metallurgical Plant, lime production waste of the Pavlodar Aluminum Plant as a binder for natural loam. Changes in physical and mechanical properties were studied for uniaxial compression strength, linear expansion coefficient, water resistance, and frost resistance of the samples. Nine mixtures were formed with different percentages of these wastes 1-20:25:4; 2-20:25:6; 3-20:25:8; 4-30:30:4; 5-30:30:6; 6-30:30:8; 7-40:35:4; 8-40:35:6; 9-40:35:8 and the mixture identifier were labeled based on the waste content and composition number. The results of strength measurement during uniaxial compression of the samples showed an almost constant increase in strength and amounted to 0.67–3.56 MPa after three days and 3.33–7.38 MPa after 90 days. This increase in compressive strength is a consequence of the addition of lime and becomes more pronounced over time. The water resistance of the developed materials after 90 days was 7.12 MPa, and the frost resistance for the same period was 7.35 MPa. The maximum values of strength determination were shown by a sample of the composition 9-40:35:8. The study of the mineral composition showed that there was no contamination with heavy metals or dangerous substances. It was determined that road materials made of red sludge, blast furnace slag, lime production waste, and natural loam mixture could be used due to their strength indicators and environmental characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production%20waste" title="production waste">production waste</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial%20compression" title=" uniaxial compression"> uniaxial compression</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resistance%20of%20materials" title=" water resistance of materials"> water resistance of materials</a>, <a href="https://publications.waset.org/abstracts/search?q=frost%20resistance%20of%20samples" title=" frost resistance of samples"> frost resistance of samples</a> </p> <a href="https://publications.waset.org/abstracts/165638/preparation-and-characterization-of-road-base-material-based-on-kazakhstan-production-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">138</span> Climate Indices: A Key Element for Climate Change Adaptation and Ecosystem Forecasting - A Case Study for Alberta, Canada</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefan%20W.%20Kienzle">Stefan W.

A climate index breaks down daily climate time series into meaningful derivatives, such as the annual number of frost days. Climate indices allow for the spatially consistent analysis of a wide range of climate-dependent variables, which enables the quantification and mapping of historical and future climate change across regions. As trends of phenomena such as the length of the growing season change differently in different hydro-climatological regions, mapping needs to be carried out at a high spatial resolution, such as the 10km by 10km Canadian Climate Grid, which has interpolated daily values from 1950 to 2017 for minimum and maximum temperature and precipitation. Climate indices form the basis for the analysis and comparison of means, extremes, trends, the quantification of changes, and their respective confidence levels. A total of 39 temperature indices and 16 precipitation indices were computed for the period 1951 to 2017 for the Province of Alberta. Temperature indices include the annual number of days with temperatures above or below certain threshold temperatures (0, +-10, +-20, +25, +30ºC), frost days, and timing of frost days, freeze-thaw days, growing or degree days, and energy demands for air conditioning and heating. Precipitation indices include daily and accumulated 3- and 5-day extremes, days with precipitation, period of days without precipitation, and snow and potential evapotranspiration. The rank-based nonparametric Mann-Kendall statistical test was used to determine the existence and significant levels of all associated trends. The slope of the trends was determined using the non-parametric Sen’s slope test. The Google mapping interface was developed to create the website albertaclimaterecords.com, from which beach of the 55 climate indices can be queried for any of the 6833 grid cells that make up Alberta. In addition to the climate indices, climate normals were calculated and mapped for four historical 30-year periods and one future period (1951-1980, 1961-1990, 1971-2000, 1981-2017, 2041-2070). While winters have warmed since the 1950s by between 4 - 5°C in the South and 6 - 7°C in the North, summers are showing the weakest warming during the same period, ranging from about 0.5 - 1.5°C. New agricultural opportunities exist in central regions where the number of heat units and growing degree days are increasing, and the number of frost days is decreasing. While the number of days below -20ºC has about halved across Alberta, the growing season has expanded by between two and five weeks since the 1950s. Interestingly, both the number of days with heat waves and cold spells have doubled to four-folded during the same period. This research demonstrates the enormous potential of using climate indices at the best regional spatial resolution possible to enable society to understand historical and future climate changes of their region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20indices" title=" climate indices"> climate indices</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20risk" title=" habitat risk"> habitat risk</a>, <a href="https://publications.waset.org/abstracts/search?q=regional" title=" regional"> regional</a>, <a href="https://publications.waset.org/abstracts/search?q=mapping" title=" mapping"> mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=extremes" title=" extremes"> extremes</a> </p> <a href="https://publications.waset.org/abstracts/154081/climate-indices-a-key-element-for-climate-change-adaptation-and-ecosystem-forecasting-a-case-study-for-alberta-canada" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154081.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">137</span> Analysis of the Properties of Hydrophobised Heat-Insulating Mortar with Perlite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Danuta%20Barnat-Hunek">Danuta Barnat-Hunek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The studies are devoted to assessing the effectiveness of hydrophobic and air entraining admixtures based on organ silicon compounds. Mortars with lightweight aggregate–perlite were the subjects of the investigation. The following laboratory tests were performed: density, open porosity, total porosity, absorptivity, capability to diffuse water vapour, compressive strength, flexural strength, frost resistance, sodium sulphate corrosion resistance and the thermal conductivity coefficient. The composition of the two mixtures of mortars was prepared: mortars without a hydrophobic admixture and mortars with cementitious waterproofing material. Surface hydrophobisation was produced on the mortars without a hydrophobic admixture using a methyl silicone resin, a water-based emulsion of methyl silicone resin in potassium hydroxide and alkyl-alkoxy-silane in organic solvents. The results of the effectiveness of hydrophobisation of mortars are the following: The highest absorption after 14 days of testing was shown by mortar without an agent (57.5%), while the lowest absorption was demonstrated by the mortar with methyl silicone resin (52.7%). After 14 days in water the hydrophobisation treatment of the samples proved to be ineffective. The hydrophobised mortars are characterized by an insignificant mass change due to freezing and thawing processes in the case of the methyl silicone resin – 1%, samples without hydrophobisation –5%. This agent efficiently protected the mortars against frost corrosion. The standard samples showed very good resistance to the pressure of sodium sulphate crystallization. Organosilicon compounds have a negative influence on the chemical resistance (weight loss about 7%). The mass loss of non-hydrophobic mortar was 2 times lower than mortar with the hydrophobic admixture. Hydrophobic and aeration admixtures significantly affect the thermal conductivity and the difference is mainly due to the difference in porosity of the compared materials. Hydrophobisation of the mortar mass slightly decreased the porosity of the mortar, and thus in an increase of 20% of its compressive strength. The admixture adversely affected the ability of the hydrophobic mortar – it achieved the opposite effect. As a result of hydrophobising the mass, the mortar samples decreased in density and had improved wettability. Poor protection of the mortar surface is probably due to the short time of saturating the sample in the preparation. The mortars were characterized by high porosity (65%) and water absorption (57.5%), so in order to achieve better efficiency, extending the time of hydrophobisation would be advisable. The highest efficiency was obtained for the surface hydrophobised with the methyl silicone resin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrophobisation" title="hydrophobisation">hydrophobisation</a>, <a href="https://publications.waset.org/abstracts/search?q=mortars" title=" mortars"> mortars</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20crystallization" title=" salt crystallization"> salt crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=frost%20resistance" title=" frost resistance"> frost resistance</a> </p> <a href="https://publications.waset.org/abstracts/56772/analysis-of-the-properties-of-hydrophobised-heat-insulating-mortar-with-perlite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56772.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> The Impact of the Mastering My Mental Fitness™-Nurses Workshops on Practical Nursing Students’ Perceived Burnout and Psychological Capital: An Embedded Mixed Methods Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linda%20Frost">Linda Frost</a>, <a href="https://publications.waset.org/abstracts/search?q=Lindsay%20Anderson"> Lindsay Anderson</a>, <a href="https://publications.waset.org/abstracts/search?q=Jana%20Borras"> Jana Borras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariel%20Dysangco"> Ariel Dysangco</a>, <a href="https://publications.waset.org/abstracts/search?q=Vimabayi%20Makwaira"> Vimabayi Makwaira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The academic environment in which nursing students are immersed in comes with many demands and expectations. Course load, clinical placements, and financial expenses are examples of the pressures facing students each semester. These pressures contribute to student stress and impact their overall well-being and mental fitness. Students' ability to cope with stress and bounce back from adversity is enhanced when we build their mental fitness. Building mental fitness has the benefit of improving physical health, relationships, self-esteem, resilience, work productivity, and overall contentment, happiness and life satisfaction. While self-care is encouraged to avoid burnout, there is a gap in literature on programs to help build nursing students’ mental health and ability to engage in self-care. There is an opportunity and a need to design programs and implement actions aimed at reducing stress and its adverse effects on nursing students. Nursing students require the support of people who understand the complexities of the nursing profession, multifaceted work environments in which they operate, and the impact these environments have on their mental fitness. Nursing academia is in the best position to ensure that tools are in place to support the next generation of nurses who face a career with significant emotional and physical demands. This is a mixed-method study using an embedded design. We utilized a pretest-posttest design to compare the difference in psychological capital (PsyCap) and burnout in students who have received the Mastering My Mental Fitness-Nurses™ (MMMF-N™) workshops (n=8) and the control group (n=9) who have not. Semi structured interviews were conducted with the eight nursing students in the intervention group, along with data from feedback forms to explore the impact of the workshops on student’s burnout and PsyCap and determine how to improve the workshops for future students. The quantitative and qualitative data will be merged using a side-by-side comparison. This will be in a discussion format that allows for the comparison of the results from both phases. The findings will be available January 2025. We anticipate that students in the control and intervention group will report similar levels of burnout. As well, students in the intervention group will indicate the benefits of the MMMF-N™ workshops through qualitative interviews and workshop feedback forms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=burnout" title="burnout">burnout</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20fitness" title=" mental fitness"> mental fitness</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing%20students" title=" nursing students"> nursing students</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20capital" title=" psychological capital"> psychological capital</a> </p> <a href="https://publications.waset.org/abstracts/192157/the-impact-of-the-mastering-my-mental-fitness-nurses-workshops-on-practical-nursing-students-perceived-burnout-and-psychological-capital-an-embedded-mixed-methods-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192157.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">23</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">135</span> Durability of Light-Weight Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudolf%20Hela">Rudolf Hela</a>, <a href="https://publications.waset.org/abstracts/search?q=Michala%20Hubertova"> Michala Hubertova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper focuses on research of durability and lifetime of dense light-weight concrete with artificial light-weight aggregate Liapor exposed to various types of aggressive environment.

Natural zeolite is one of the raw materials which can partly substitute Portland cement. The effort to reduce the amount of Portland cement used in concrete production is brings both economical as well as ecological benefits. The paper presents the properties of concrete containing natural zeolite as an active admixture in the concrete which partly substitutes Portland cement. The properties discussed here bring information about the basic mechanical properties and frost resistance of concrete containing zeolite. The properties of concretes with the admixture of zeolite are compared with a reference concrete with no content of zeolite.

More importantly, it will be very useful to give an interpretation of each of the factors in terms of conditional probabilities. This paper considers a semantic interpretation of the factors involved in computing marginal probabilities in Bayesian networks.

It follows on the promising results of a preliminary study of STEAM (Science, Technology, Engineering, Arts, and Mathematics) education during live concerts, funded by the National Science Foundation with the Baltimore Symphony Orchestra. For the Bearman Study, audience groups were recruited to attend two previously recorded concerts of the National Orchestral Institute (NOI) in 2020 or the Utah Symphony in 2021. They used a smartphone app called EnCue to present real-time program notes about the music being performed. Short notes along with visual information (photos and score fragments) were designed to provide historical, cultural, biographical, and theoretical information at specific moments in the music where that information would be most pertinent, generally spaced 2-3 minutes apart to avoid distraction. The music performed included Dvorak Symphony No. 8 and Mahler Symphony No. 5 at NOI, and Mendelssohn Scottish Symphony and Richard Strauss Metamorphosen with the Utah Symphony, all standard repertoire for symphony orchestras. During each phase of the study (2020 and 2021), participants were randomly assigned to use the app to view program notes during the first concert or to use the app during the second concert. A total of 139 participants (67 in 2020 and 72 in 2021) completed three online questionnaires, one before attending the first concert, one immediately after the concert, and the third immediately after the second concert. Questionnaires assessed demographic background, expertise in music, engagement during the concert, learning of content about the composers and the symphonies, and interest in the future use of the app. In both phases of the study, participants demonstrated that they learned content presented on the app, evidenced by the fact that their multiple-choice test scores were significantly higher when they used the app than when they did not. In addition, most participants indicated that using the app enriched their experience of the concert. Overall, they were very positive about their experience using the app for real-time learning and they expressed interest in using it in the future at both live and streaming concerts. Results confirmed that informal real-time learning during concerts is possible and can generate enhanced engagement and interest in classical music. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audience%20engagement" title="audience engagement">audience engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20education" title=" informal education"> informal education</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20technology" title=" music technology"> music technology</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20learning" title=" real-time learning"> real-time learning</a> </p> <a href="https://publications.waset.org/abstracts/141533/enhancing-audience-engagement-informal-music-learning-during-classical-concerts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">131</span> Freshwater Source of Sapropel for Healthcare </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilona%20Pavlovska">Ilona Pavlovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Aneka%20Klavina"> Aneka Klavina</a>, <a href="https://publications.waset.org/abstracts/search?q=Agris%20Auce"> Agris Auce</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivars%20Vanadzins"> Ivars Vanadzins</a>, <a href="https://publications.waset.org/abstracts/search?q=Alise%20Silova"> Alise Silova</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Komarovska"> Laura Komarovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Paegle"> Linda Paegle</a>, <a href="https://publications.waset.org/abstracts/search?q=Baiba%20Silamikele"> Baiba Silamikele</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Dobkevica"> Linda Dobkevica</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Freshwater sapropel is a common material formed by complex biological transformations of Holocene sediments in the water basement of the lakes in Latvia that has the potential to be used as medical mud. Sapropel forms over a long period in shallow waters by slowly decomposing organic sediment and has different compositions depending on the location of the source, surroundings, the water regime, etc. Official geological survey of Latvia lakes, from Latvian lake database (ezeri.lv), used in the selection of the area of the exploration. The multifunctional effect of sapropel on the whole organism explained by its complex chemical and biological structure. This unique, organic substance and its ability to maintain heat for a long time ensures deep tissue warming and has a positive effect on the treatment of various joint and skin diseases. Sapropel is a valuable resource with multiple areas of application. Investigation of sapropel sediments and survey of the five sites selected according to the criteria performed in the current study. Also, our study includes sampling at different depths and their initial treatment, evaluation of external signs, and study of physical-chemical parameters, as well as analysis of biochemical parameters and evaluation of microbiological indicators. The main selection criteria were sapropel deposits depth, hydrological regime, the history of agriculture next to the lake, and the potential exposure to industrial waste. One hundred and five sapropel samples obtained from five lakes (Audzelu, Dunakla, Ivusku, Zielu, and Mazars Kivdalova) during the wintertime. The main goal of the study is to carry out detailed and systematic research on the medical properties of sapropel to be obtained in Latvia, to promote its scientifically based use in balneology, to develop new medical procedures and services, and to promote the development of new exportable products. Latvian freshwater sapropel could be used as raw material for getting sapropel extract and use it as a remedy. All mentioned above brings us to the main question for sapropel usage in medicine, balneology, and pharmacy “how to develop quality criteria for raw sapropel and its extracts.

The model uses the finite difference method and it is convenient for applications. The model is validated with an analytical solution and a field case with soil temperature distributions. It is then applied to the idealized river bank in terms of partially and fully saturated conditions with or without ice cover influence. Simulated results illustrate the response processes of the river bank to seasonal air temperature variations. It promotes the understanding of freeze and thaw processes in river banks and prepares for further investigation of frost and thaw impacts on riverbank stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=freeze%20and%20thaw" title="freeze and thaw">freeze and thaw</a>, <a href="https://publications.waset.org/abstracts/search?q=riverbanks" title=" riverbanks"> riverbanks</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20model" title=" 2D model"> 2D model</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20conduction" title=" heat conduction"> heat conduction</a> </p> <a href="https://publications.waset.org/abstracts/131174/two-dimensional-modeling-of-seasonal-freeze-and-thaw-in-an-idealized-river-bank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131174.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">129</span> Present and Future Climate Extreme Indices over Sinai Peninsula, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Roushdi">Mahmoud Roushdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hany%20Mostafa"> Hany Mostafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Kheireldin"> Khaled Kheireldin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sinai Peninsula and Suez Canal Corridor are promising and important economic regions in Egypt due to the unique location and development opportunities.

Accordingly, this paper aims to assess the climate extreme indices in through the last 35 year over Sinai Peninsula and Suez Canal Corridor in addition to predict the climate extreme indices up to 2100. Present and future climate indices were analyzed with using different RCP scenarios 4.5 and 8.5 from 2010 until 2100 for Sinai Peninsula and Suez Canal Corridor. Furthermore, both CanESM and HadGEM2 global circulation models were used. The results indicate that the number of summer days is predicted to increase, on the other hand the frost days is predicted to decrease. Moreover, it is noted a slight positive trend for the percentile of wet and extremely days R95p and R99p for RCP4.5 and negative trend for RCP8.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=extreme%20indices" title=" extreme indices"> extreme indices</a>, <a href="https://publications.waset.org/abstracts/search?q=RCP" title=" RCP"> RCP</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinai%20Peninsula" title=" Sinai Peninsula"> Sinai Peninsula</a> </p> <a href="https://publications.waset.org/abstracts/36682/present-and-future-climate-extreme-indices-over-sinai-peninsula-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36682.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">436</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">128</span> Family Business Succession through the Eye of the Upper Echelon Theory: A Phenomenological Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruswiati%20Suryasaputra">Ruswiati Suryasaputra</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Salim"> Linda Salim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This concept paper, initially a proposal for the completion of the degree of Doctor of Philosophy, is seeking to gain more understanding of family business succession in order to extend the average lifespan of family business that has shrunken significantly for the past 20 years. While multitude studies have been done in family business succession, the average lifespan of a family business continues to decline sharply over the past two decades to only 24 years, or 1.5 generations, in 2010, from 50-60 years, equivalent to 3 generations, as recently as 1990. While the qualitative approach of this study will not churn a theoretical framework unique to the family business field, it will bring to the surface important issues during a family business succession process that have been hidden behind the mostly profit-making issues that have been the main highlight of the family business field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=family%20business" title="family business">family business</a>, <a href="https://publications.waset.org/abstracts/search?q=succession" title=" succession"> succession</a>, <a href="https://publications.waset.org/abstracts/search?q=nepotism" title=" nepotism"> nepotism</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20studies" title=" family studies"> family studies</a> </p> <a href="https://publications.waset.org/abstracts/23791/family-business-succession-through-the-eye-of-the-upper-echelon-theory-a-phenomenological-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23791.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">541</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">127</span> The Real Estate Market Sustainability Concept and Its Implementation in Management of Real Estate Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linda%20Kau%C5%A1kale">Linda Kauškale</a>, <a href="https://publications.waset.org/abstracts/search?q=Ineta%20Geipele"> Ineta Geipele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the rapidly changing external environment, portfolio management strategies became closely interconnected with real estate industry development and macroeconomic development tendencies.

The recovered sensible and latent heat, fan preheating use for frost prevention and heating energy consumed by heating coil after the ventilator is compared for the air handling unit combined heat and energy exchanger respectively. A concept of coefficient of performance of air handling unit is presented and applied to assess the energy use of air handling unit (AHU) in cold climates. The analytic results indicate downsizing of the preheating coil before exchanger and heating coils after exchanger are expected since the required power to preheat and condition the air is reduced compared to heat exchanger when the MEE is integrated with AHU. Simultaneously, a superior ratio of energy recovered (RER) is obtained from AHU build-in a counter-flow MEE. The AHU with sensible-only heat exchanger has noticeably low RER, around 1 at low outdoor air temperature where the maximum energy rate is desired to condition the severe cold and dry air. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membrane%20energy%20exchanger" title="membrane energy exchanger">membrane energy exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20climate" title=" cold climate"> cold climate</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficient%20building" title=" energy efficient building"> energy efficient building</a>, <a href="https://publications.waset.org/abstracts/search?q=HVAC" title=" HVAC"> HVAC</a> </p> <a href="https://publications.waset.org/abstracts/53355/energy-saving-and-performance-evaluation-of-an-air-handling-unit-integrated-with-a-membrane-energy-exchanger-for-cold-climates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53355.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">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> Features of Soil Formation in the North of Western Siberia in Cryogenic Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tatiana%20V.%20Raudina">Tatiana V.

These areas are widely used because there are concentrated valuable natural resources. Therefore to explore of cryosols it is important due to the significant increase of anthropogenic stress as well as the problem of global climate change. In the north of Western Siberia permafrost phenomena is widespread. Permafrost as a factor of soil formation and cryogenesis as a process have a great impact on the soil formation of these areas. Based on the research results of permafrost-affected soils tundra landscapes formed in the central part of the Tazovskiy Peninsula in cryogenic conditions, data were obtained which characterize the morphological features of soils. The specificity of soil cover distribution and manifestation of soil-forming processes within the study area are noted. Permafrost features such as frost cracking, cryoturbation, thixotropy, movement of humus are formed. The formation of these features is increased with the development of the territory. As a consequence, there is a change in the components of the environment and the destruction of the soil cover. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gleyed%20and%20nongleyed%20soils" title="gleyed and nongleyed soils">gleyed and nongleyed soils</a>, <a href="https://publications.waset.org/abstracts/search?q=permafrost" title=" permafrost"> permafrost</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20cryogenesis%20%28pedocryogenesis%29" title=" soil cryogenesis (pedocryogenesis)"> soil cryogenesis (pedocryogenesis)</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-forming%20macroprocesses" title=" soil-forming macroprocesses"> soil-forming macroprocesses</a> </p> <a href="https://publications.waset.org/abstracts/8294/features-of-soil-formation-in-the-north-of-western-siberia-in-cryogenic-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8294.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">350</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">121</span> Business Process Mashup</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fethia%20Zenak">Fethia Zenak</a>, <a href="https://publications.waset.org/abstracts/search?q=Salima%20Benbernou"> Salima Benbernou</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Zaoui"> Linda Zaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, many companies are based on process development from scratch to achieve their business goals. The process development is not trivial and the main objective of enterprise managing processes is to decrease the software development time. Several concepts have been proposed in the field of business process-based reused development, known as BP Mashup. This concept consists of reusing existing business processes which have been modeled in order to respond to a particular goal. To meet user process requirements, our contribution is to mix parts of processes as 'processes fragments' components to build a new process (i.e. process mashup). The main idea of our paper is to offer graphical framework tool for both creating and running processes mashup. Allow users to perform a mixture of fragments, using a simple interface with set of graphical mixture operators based on a proposed formal model. A process mashup and mixture behavior are described within a new specification of a high-level language, language for process mashup (BPML). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process" title="business process">business process</a>, <a href="https://publications.waset.org/abstracts/search?q=mashup" title=" mashup"> mashup</a>, <a href="https://publications.waset.org/abstracts/search?q=fragments" title=" fragments"> fragments</a>, <a href="https://publications.waset.org/abstracts/search?q=bp%20mashup" title=" bp mashup"> bp mashup</a> </p> <a href="https://publications.waset.org/abstracts/4098/business-process-mashup" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4098.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">635</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">120</span> Development of Extemporaneous Pediatric Syrup of Prednisone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amel%20Chenafa">Amel Chenafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sihem%20Boulenouar"> Sihem Boulenouar</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Aoued"> Linda Aoued</a>, <a href="https://publications.waset.org/abstracts/search?q=Imane%20Sediri"> Imane Sediri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismahan%20Djebbar"> Ismahan Djebbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Adil%20Selka"> Mohamed Adil Selka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The specialties intended for adults are often inadequate marketed for pediatric use, such as for a galenic form or in the dosage. For an industrial, development of a pediatric drug is confronted to various problems. So, the hospital pharmacies have to respond to adaptation needs of pharmaceutical forms for pediatric use. The objective of our work is to develop an oral form of prednisone for pediatric use since no adapted form to children is commercialized. Materials and Methods: Therefore an extemporaneous syrup of prednisone was prepared at the concentration of 0,5mg/ml from 5mg tablets and stored in amber glass bottles. Organoleptic and microbiological stability was studied in two temperatures: 5°C and 25°C, and evaluated at D0, D15, and D30. Results: No organoleptic changes have been detected on the syrup conserved at 25 and 5°C. The results show that there is no presence of bacteria, yeasts, and molds in the syrups stored at both temperatures during the analysis period. Conclusion: Sheltered from light, the developed syrup of prednisone remained stable at room temperature and/or refrigerator for 30 days. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extemporaneous%20syrup" title="extemporaneous syrup">extemporaneous syrup</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20drug" title=" pediatric drug"> pediatric drug</a>, <a href="https://publications.waset.org/abstracts/search?q=prednisone" title=" prednisone"> prednisone</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/32721/development-of-extemporaneous-pediatric-syrup-of-prednisone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32721.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">386</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">119</span> Dental Management Particularities of Werner Syndrome: A Report of Two Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emna%20Abid">Emna Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Chebbi"> Linda Chebbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosra%20Mabrouk"> Yosra Mabrouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Labidi"> Amel Labidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Mansour"> Lamia Mansour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Werner syndrome (WS) is a rare genetic disorder inherited in an autosomal recessive pattern characterized by accelerated aging. While extensive research has been conducted on its systemic manifestations, the specific dental implications of WS remain poorly understood. The medical history and the oral health status of two patients diagnosed with WS were detailed. Our findings revealed a high prevalence of dental problems in both patients, including periodontitis, xerostomia, and temporomandibular joint disorders. This article aims to investigate the dental challenges faced by individuals with WS as well as the prosthetic options envisaged through two clinical cases contributing to a deeper understanding of the dental implications of WS and to choose the appropriate prosthetic solution in this population. Future research should focus on larger scale studies and clinical trials to validate these proposed strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult%20progeria" title="adult progeria">adult progeria</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20symptoms" title=" clinical symptoms"> clinical symptoms</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20manifestations" title=" oral manifestations"> oral manifestations</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20care" title=" dental care"> dental care</a>, <a href="https://publications.waset.org/abstracts/search?q=prosthetic%20management" title=" prosthetic management"> prosthetic management</a> </p> <a href="https://publications.waset.org/abstracts/186691/dental-management-particularities-of-werner-syndrome-a-report-of-two-cases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186691.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">51</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">118</span> Exploring Electroactive Polymers for Dynamic Data Physicalization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Dauner">Joanna Dauner</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Friedrich"> Jan Friedrich</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Elsner"> Linda Elsner</a>, <a href="https://publications.waset.org/abstracts/search?q=Kora%20Kimpel"> Kora Kimpel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Active materials such as Electroactive Polymers (EAPs) are promising for the development of novel shape-changing interfaces. This paper explores the potential of EAPs in a multilayer unimorph structure from a design perspective to investigate the visual qualities of the material for dynamic data visualization and data physicalization. We discuss various concepts of how the material can be used for this purpose. Multilayer unimorph EAPs are of particular interest to designers because they can be easily prototyped using everyday materials and tools. By changing the structure and geometry of the EAPs, their movement and behavior can be modified. We present the results of our preliminary user testing, where we evaluated different movement patterns. As a result, we introduce a prototype display built with EAPs for dynamic data physicalization. Finally, we discuss the potentials and drawbacks and identify further open research questions for the design discipline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroactive%20polymer" title="electroactive polymer">electroactive polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=shape-changing%20interfaces" title=" shape-changing interfaces"> shape-changing interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20material%20interfaces" title=" smart material interfaces"> smart material interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20physicalization" title=" data physicalization"> data physicalization</a> </p> <a href="https://publications.waset.org/abstracts/164699/exploring-electroactive-polymers-for-dynamic-data-physicalization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164699.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">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">117</span> Adsorption of Lead and Zinc Ions Onto Chemical Activated Millet Husk: Equilibrium and Kinetics Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hilary%20Rutto">Hilary Rutto</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Sibali"> Linda Sibali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the adsorption of lead and zinc ions from aqueous solutions by modified millet husk has been investigated. The effects of different parameters, such as pH, adsorbent dosage, concentration, temperature, and contact time, have been investigated. The results of the experiments showed that the adsorption of both metal ions increased by increasing pH values up to 11. Adsorption process was initially fast. The adsorption rate decreased then until it reached to equilibrium time of 120 min for both lead and zinc ions. The Langmuir, Freundlich, Dubinin-Radushkevich (D-R), and thermodynamic models (Gibbs free energy) were used to determine the isotherm parameters associated with the adsorption process. The positive values of Gibbs free energy change indicated that reaction is not spontaneous. Experimental data were also evaluated in terms of kinetic characteristics of adsorption, and it was found that adsorption process for both metal ions followed pseudo-first order for zinc and pseudo-second-order for lead. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zinc" title="zinc">zinc</a>, <a href="https://publications.waset.org/abstracts/search?q=lead" title=" lead"> lead</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=millet%20husks" title=" millet husks"> millet husks</a> </p> <a href="https://publications.waset.org/abstracts/130830/adsorption-of-lead-and-zinc-ions-onto-chemical-activated-millet-husk-equilibrium-and-kinetics-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130830.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">116</span> Rotor Concepts for the Counter Flow Heat Recovery Fan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Speer">Christoph Speer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Decentralized ventilation systems should combine a small and economical design with high aerodynamic and thermal efficiency. The Counter Flow Heat Recovery Fan (CHRF) provides the ability to meet these requirements by using only one cross flow fan with a large number of blades to generate both airflows and which simultaneously acts as a regenerative counter flow heat exchanger. The successful development of the first laboratory prototype has shown the potential of this ventilation system. Occurring condensate on the surfaces of the fan blades during the cold and dry season can be recovered through the characteristic mode of operation. Hence the CHRF provides the possibility to avoid the need for frost protection and condensate drain. Through the implementation of system-specific solutions for flow balancing and summer bypass the required functionality is assured. The scalability of the CHRF concept allows the use in renovation as well as in new buildings from single-room devices through to systems for office buildings. High aerodynamic and thermal efficiency and the lower number of required mechatronic components should enable a reduction in investment as well as operating costs. The rotor is the key component of the system, the requirements and possible implementation variants are presented. <p class="card-text"><strong>Keywords:</strong> <a
