It functions as a cooling agent. Mineral oil has long been used in transformers. Mineral oil has a high dielectric strength, which allows it to withstand high temperatures. Mineral oil's main disadvantage is that it is not environmentally friendly and can be dangerous to the environment. The features of breakdown voltage (BDV), viscosity, flash point, and fire point are measured and reported in this study, and the characteristics of olive oil are compared to the characteristics of mineral oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title="antioxidants">antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer%20oil" title=" transformer oil"> transformer oil</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20oil" title=" mineral oil"> mineral oil</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20oil" title=" olive oil"> olive oil</a> </p> <a href="https://publications.waset.org/abstracts/147698/improving-the-liquid-insulation-performance-with-antioxidants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147698.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">150</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">836</span> Removal of Deposits and Improvement of Shelf Life in CO₂-Rich Mineral Water by Ozone-Microbubbles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Un%20Hwa%20Choe">Un Hwa Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Hyon%20Choe"> Jong Hyon Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Jun%20Kim"> Yong Jun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to effectively remove Fe2+ by using ozone microbubbles in bottled mineral water to prevent sediment from occurring during storage and increase shelf life. By considering the characteristics of mineral water with low solubility of ozone and high CO2 content, a suitable ozone injection step was chosen and a new mineral water treatment method using microbubbles was proposed. As a result of the treatment of the bottled mineral water with ozone microbubbles, the iron ion concentration was reduced from 0.14 mg/L to 0.01 mg/L, and the shelf life increased to 360 days. During the treatment, the concentrations of K+ and Na+ were almost unchanged, and the deposition time was reduced to one-third compared to the natural oxidation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82-rich%20mineral%20water" title="CO₂-rich mineral water">CO₂-rich mineral water</a>, <a href="https://publications.waset.org/abstracts/search?q=ozone-micro%20bubble" title=" ozone-micro bubble"> ozone-micro bubble</a>, <a href="https://publications.waset.org/abstracts/search?q=shelf%20life" title=" shelf life"> shelf life</a>, <a href="https://publications.waset.org/abstracts/search?q=bottled%20mineral%20water" title=" bottled mineral water"> bottled mineral water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title=" water treatment"> water treatment</a> </p> <a href="https://publications.waset.org/abstracts/178817/removal-of-deposits-and-improvement-of-shelf-life-in-co2-rich-mineral-water-by-ozone-microbubbles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178817.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">85</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">835</span> Mesotrione and Tembotrione Applied Alone or in Tank-Mix with Atrazine on Weed Control in Elephant Grass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20M.%20Brighenti">Alexandre M.

The treatments were as follows: mesotrione (0.072 and 0.144 kg ha<sup>-1</sup> + 0.5% v/v mineral oil - Assist®), tembotrione (0.075 and 0.100 kg ha<sup>-1</sup> + 0.5% v/v mineral oil - Aureo®), atrazine + mesotrione (1.25 + 0.072 kg ha<sup>-1</sup> + 0.5% v/v mineral oil - Assist®), atrazine + tembotrione (1.25 + 0.100 kg ha<sup>-1</sup> + 0.5% v/v mineral oil - Aureo®), atrazine + mesotrione (1.25 + 0.072 kg ha<sup>-1</sup>), atrazine + tembotrione (1.25 + 0.100 kg ha<sup>-1</sup>) and two controls (hoed and unhoed check). Two application rates of mesotrione with the addition of mineral oil or the tank mixture of atrazine plus mesotrione, with or without the addition of mineral oil, did not provide injuries capable to reduce elephant grass forage yield. Tembotrione was phytotoxic to elephant grass when applied with mineral oil. Atrazine and tembotrione in a tank-mix, with or without mineral oil, were also phytotoxic to elephant grass. All treatments provided satisfactory weed control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forage" title="forage">forage</a>, <a href="https://publications.waset.org/abstracts/search?q=Napier%20grass" title=" Napier grass"> Napier grass</a>, <a href="https://publications.waset.org/abstracts/search?q=pasture" title=" pasture"> pasture</a>, <a href="https://publications.waset.org/abstracts/search?q=Pennisetum%20purpureum" title=" Pennisetum purpureum"> Pennisetum purpureum</a>, <a href="https://publications.waset.org/abstracts/search?q=weeds" title=" weeds"> weeds</a> </p> <a href="https://publications.waset.org/abstracts/79651/mesotrione-and-tembotrione-applied-alone-or-in-tank-mix-with-atrazine-on-weed-control-in-elephant-grass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79651.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">283</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">834</span> Genetic Analysis of Iron, Phosphorus, Potassium and Zinc Concentration in Peanut</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20B.%20C.">Ajay B.

Basic information on genetics and inheritance of these mineral elements is very scarce. Hence, in the present study inheritance (using additive-dominance model) and association of mineral elements was studied in two peanut crosses. Dominance variance (H) played an important role in the inheritance of P, K, Fe and Zn in peanut pods. Average degree of dominance for most of the traits was greater than unity indicating over dominance for these traits. Significant associations were also observed among mineral elements both in F2 and F3 generations but pod yield had no associations with mineral elements (with few exceptions). Di-allele/bi-parental mating could be followed to identify high yielding and mineral dense segregates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation" title="correlation">correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=dominance%20variance" title=" dominance variance"> dominance variance</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20elements" title=" mineral elements"> mineral elements</a>, <a href="https://publications.waset.org/abstracts/search?q=peanut" title=" peanut"> peanut</a> </p> <a href="https://publications.waset.org/abstracts/14731/genetic-analysis-of-iron-phosphorus-potassium-and-zinc-concentration-in-peanut" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14731.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">413</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">833</span> Effects of Water Content on Dielectric Properties of Mineral Transformer Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suwarno">Suwarno</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Helmi%20Prakoso"> M.

The insulation quality of mineral oil is affecting the operation process of high voltage transformer. There are many contaminations which could decrease the insulation quality of mineral oil. One of them is water. This research talks about the effect of water content on dielectric properties, physic properties, and partial discharge pattern on mineral oil. Samples were varied with 10 varieties of water content value. And then all samples were tested to measure the dielectric properties, physic properties, and partial discharge pattern. The result of this research showed that an increment of water content value would decrease the insulation quality of mineral oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dielectric%20properties" title="dielectric properties">dielectric properties</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20voltage%20transformer" title=" high voltage transformer"> high voltage transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20oil" title=" mineral oil"> mineral oil</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20content" title=" water content"> water content</a> </p> <a href="https://publications.waset.org/abstracts/36856/effects-of-water-content-on-dielectric-properties-of-mineral-transformer-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36856.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">399</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">832</span> Consumer Market for Mineral Water and Development Policy in Georgia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulnaz%20Erkomaishvili">Gulnaz Erkomaishvili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper discusses mineral water consumer market and development policy in Georgia, the tools and measures, which will contribute to the production of mineral waters and increase its export.

At the same time compost can play an important role in the nitrogen cycle and it can influence leaching of mineral nitrogen from soil to underground water. This paper deals with the influence of compost addition and mineral nitrogen fertilizer on leaching of mineral nitrogen, nitrogen availability in microbial biomass and plant biomass production in the lysimetric experiment. Twenty-one lysimeters were filed with topsoil and subsoil collected in the area of protection zone of underground source of drinking water - Březová nad Svitavou. The highest leaching of mineral nitrogen was detected in the variant fertilized only mineral nitrogen fertilizer (624.58 mg m-2), the lowest leaching was recorded in the variant with high addition of compost (315.51 mg m-2). On the other hand, losses of mineral nitrogen are not in connection with the losses of available form of nitrogen in microbial biomass.

First of all, the engineering properties of the ladle furnace slag and lime were compared, and then the mineral filler was mixed with bitumen to form the asphalt cement mastics in order to analyze the influence of the ladle furnace slag on the properties of asphalt cement mastics, and lastly, the mineral filler was used in the EAF asphalt concrete to analyze its feasibility of using ladle furnace slag as a mineral filler. The study result shows that the ladle furnace slag and the lime have no obvious difference in their physical properties, and from the energy dispersive spectrometer (EDS) test results, we know that the lime and the ladle furnace slag have similar elemental composition, but the Ca found in the ladle furnace slag belongs to CaO, and the lime belongs to CaCO3, therefore the ladle furnace slag has the property of expansion. According to the test results, the viscosity of asphalt cement mastics will increase with the increase in the use of mineral filler. Since the ladle furnace slag has more CaO content, the viscosity of the asphalt cement mastics with ladle furnace slag will increase more than using lime as mineral filler in the asphalt cement mastics, and the use of ladle furnace slag only needs to be 2% in order to achieve the effect of anti-peeling which is 6% for lime. From the related test results of EAF asphalt concrete, it is known that the maximum stability value can be obtained when the use of mineral filler is about 5%. When the ladle furnace slag is used as the mineral filler, it can improve the stiffness, indirect tension strength, spalling resistance, and thermal insulation of EAF asphalt concrete, which also indicates that using the ladle furnace slag as the mineral filler of bitumen can help to improve the durability of the asphalt pavement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ladle%20furnace%20slag" title="ladle furnace slag">ladle furnace slag</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20filler" title=" mineral filler"> mineral filler</a>, <a href="https://publications.waset.org/abstracts/search?q=asphalt%20cement%20mastics" title=" asphalt cement mastics"> asphalt cement mastics</a>, <a href="https://publications.waset.org/abstracts/search?q=EAF%20asphalt%20concrete" title=" EAF asphalt concrete"> EAF asphalt concrete</a> </p> <a href="https://publications.waset.org/abstracts/170204/study-of-ladle-furnace-slag-as-mineral-filler-in-asphalt-concrete-with-electric-arc-furnace-slag" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170204.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">85</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">828</span> Combined Machine That Fertilizes Evenly under Plowing on Slopes and Planning an Experiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qurbanov%20Huseyn%20Nuraddin">Qurbanov Huseyn Nuraddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The results of scientific research on a machine that pours an equal amount of mineral fertilizer under the soil to increase the productivity of grain in mountain farming and obtain quality grain are substantiated. The average yield of the crop depends on the nature of the distribution of fertilizers in the soil. Therefore, the study of effective energy-saving methods for the application of mineral fertilizers is the actual task of modern agriculture. Depending on the type and variety of plants in mountain farming, there is an optimal norm of mineral fertilizers. Applying an equal amount of fertilizer to the soil is one of the conditions that increase the efficiency of the field.

One of the most important sources of mineral raw materials are primary deposits. The efficient management of them, including extraction, will ensure competitiveness of the European economy. A critical element of this approach is mineral deposits safeguarding and the most important tool - spatial planning. The safeguarding of deposits should be understood as safeguarding of land access, and safeguarding of area against development, which may (potential) prevent the use of the deposit and the necessary mining activities. Many European Union countries successfully integrated their mineral policy and spatial policy, which has ensured the proper place of mineral deposits in their spatial planning systems. These, in turn, are widely recognized as the most important mineral deposit safeguarding tool, the essence of which is to ensure long-term access to its resources. The examples of Austria, Portugal, Slovakia, Czech Republic, Sweden, and the United Kingdom, discussed in the paper, are often mentioned as examples of good practices in this area. Although none of these countries managed to avoid cases of social and environmental conflicts related to mining activities, the solutions they implement certainly deserve special attention. And for many countries, including Poland, they can be a potential source of solutions aimed at improving the protection of mineral deposits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mineral%20deposits" title="mineral deposits">mineral deposits</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20planning" title=" land use planning"> land use planning</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20deposit%20safeguarding" title=" mineral deposit safeguarding"> mineral deposit safeguarding</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20practices" title=" European practices"> European practices</a> </p> <a href="https://publications.waset.org/abstracts/144213/mineral-deposits-in-spatial-planning-systems-review-of-european-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144213.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">171</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">823</span> Phytochemical Screening, Anti-Microbial and Mineral Determination of Stachtarpheta indica Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Isah%20Lakan">Ibrahim Isah Lakan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasiru%20Ibrahim"> Nasiru Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> These Phytochemical screening, Antimicrobial activities and mineral Determination of aqueous extract of Stachtarpheta indica were assessed.

In this regard, the search for new methods that could determine the indicators not only of the mineral density, but of the bone tissue quality, is a logical step for diagnostic optimization. One of these methods is the evaluation of trabecular bone quality. The aim of this study was to examine the quality and mineral density of spine bone tissue, femoral neck, and body composition of women depending on the duration of the postmenopausal period, to determine the correlation of body fat with indicators of bone mineral density and quality. The study examined 179 women in premenopausal and postmenopausal periods. The patients were divided into the following groups: Women in the premenopausal period and women in the postmenopausal period at various stages (early, middle, late postmenopause). A general examination and study of the above parameters were conducted with General Electric X-ray densitometer. The results show that bone quality and mineral density probably deteriorate with advancing of postmenopausal period. Total fat and lean mass ratio is not likely to change with age. In the middle and late postmenopausal periods, the bone tissue mineral density of the spine and femoral neck increases along with total fat mass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title="osteoporosis">osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20mineral%20density" title=" bone tissue mineral density"> bone tissue mineral density</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20quality" title=" bone quality"> bone quality</a>, <a href="https://publications.waset.org/abstracts/search?q=fat%20mass" title=" fat mass"> fat mass</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20mass" title=" lean mass"> lean mass</a>, <a href="https://publications.waset.org/abstracts/search?q=postmenopausal%20osteoporosis" title=" postmenopausal osteoporosis"> postmenopausal osteoporosis</a> </p> <a href="https://publications.waset.org/abstracts/66298/bone-mineral-density-and-quality-body-composition-of-women-in-the-postmenopausal-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66298.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">343</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">821</span> Evaluation and Provenance Studies of Heavy Mineral Deposits in Recent Sediment of Ologe Lagoon, South Western, Nigeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mayowa%20Philips%20Ibitola">Mayowa Philips Ibitola</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinade-Solomon%20Olorunfemi"> Akinade-Solomon Olorunfemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abe%20Oluwaseun%20Banji"> Abe Oluwaseun Banji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy minerals studies were carried out on eighteen sediment samples from Ologe lagoon located at Lagos Barrier complex, with the aim of evaluating the heavy mineral deposits and determining the provenance of the sediments. The samples were subjected to grain analysis techniques in order to collect the finest grain size. Separation of heavy minerals from the samples was done with the aid of bromoform to enable petrographic analyses of the heavy mineral suite, under the polarising microscope. The data obtained from the heavy mineral analysis were used in preparing histograms and pie chart, from which the individual heavy mineral percentage distribution and ZTR index were derived. The percentage composition of the individual heavy mineral analyzed are opaque mineral 63.92%, Zircon 12.43%, Tourmaline 5.79%, Rutile 13.44%, Garnet 1.74% and Staurolite 3.52%. The calculated zircon, tourmaline, rutile index in percentage (ZTR) varied between 76.13 -92.15%, average garnet-zircon index (GZI), average rutile-zircon index (RuZI) and average staurolite-zircon index values in all the stations are 16.18%, 54.33%, 25.11% respectively. The mean ZTR index percentage value is 85.17% indicates that the sediments within the lagoon are mineralogically matured. The high percentage of zircon, rutile, and tourmaline indicates an acid igneous rock source for the sediments. However, the low percentage of staurolite, rutile and garnet occurrence indicates sediment of metamorphic rock source input. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lagoon" title="lagoon">lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=provenance" title=" provenance"> provenance</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20mineral" title=" heavy mineral"> heavy mineral</a>, <a href="https://publications.waset.org/abstracts/search?q=ZTR%20index" title=" ZTR index"> ZTR index</a> </p> <a href="https://publications.waset.org/abstracts/90033/evaluation-and-provenance-studies-of-heavy-mineral-deposits-in-recent-sediment-of-ologe-lagoon-south-western-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90033.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">174</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">820</span> The Potential Effect of Biochar Application on Microbial Activities and Availability of Mineral Nitrogen in Arable Soil Stressed by Drought</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helena%20Dvo%C5%99%C3%A1%C4%8Dkov%C3%A1">Helena Dvořáčková</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Elbl"> Jakub Elbl</a>, <a href="https://publications.waset.org/abstracts/search?q=Irina%20Mikajlo"> Irina Mikajlo</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%C3%ADn%20Kintl"> Antonín Kintl</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Hyn%C5%A1t"> Jaroslav Hynšt</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Urb%C3%A1nkov%C3%A1"> Olga Urbánková</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Z%C3%A1hora"> Jaroslav Záhora</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Application of biochar to arable soils represents a new approach to restore soil health and quality. Many studies reported the positive effect of biochar application on soil fertility and development of soil microbial community. Moreover biochar may affect the soil water retention, but this effect has not been sufficiently described yet. Therefore this study deals with the influence of biochar application on: microbial activities in soil, availability of mineral nitrogen in soil for microorganisms, mineral nitrogen retention and plant production. To demonstrate the effect of biochar addition on the above parameters, the pot experiment was realized. As a model crop, Lactuca sativa L. was used and cultivated from December 10th 2014 till March 22th 2015 in climate chamber in thoroughly homogenized arable soil with and without addition of biochar. Five variants of experiment (V1–V5) with different regime of irrigation were prepared. Variants V1–V2 were fertilized by mineral nitrogen, V3–V4 by biochar and V5 was a control. The significant differences were found only in plant production and mineral nitrogen retention. The highest content of mineral nitrogen in soil was detected in V1 and V2, about 250 % in comparison with the other variants. The positive effect of biochar application on soil fertility, mineral nitrogen availability was not found. On the other hand results of plant production indicate the possible positive effect of biochar application on soil water retention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arable%20soil" title="arable soil">arable soil</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20nitrogen" title=" mineral nitrogen"> mineral nitrogen</a> </p> <a href="https://publications.waset.org/abstracts/33497/the-potential-effect-of-biochar-application-on-microbial-activities-and-availability-of-mineral-nitrogen-in-arable-soil-stressed-by-drought" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33497.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">426</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">819</span> Energy Saving of the Paint with Mineral Insulators: Simulation and Study on Different Climates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20Azemati">A.

In this study, a range of wall paints with different absorption coefficient in different climates has been investigated. In order to study these effects, heating and cooling loads of a common building with different ordinary paints and paint with mineral coating have been calculated. The effect of building paint in different climatic condition was studied and comparison was done between ordinary paints and paint with mineral insulators in temperate climate to obtain optimized energy consumption. The results have been shown that coatings with inorganic micro particles as insulation reduce the energy consumption of buildings around 14%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate" title="climate">climate</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=inorganic" title=" inorganic"> inorganic</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20coating" title=" mineral coating"> mineral coating</a> </p> <a href="https://publications.waset.org/abstracts/42325/energy-saving-of-the-paint-with-mineral-insulators-simulation-and-study-on-different-climates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42325.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">268</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">818</span> Safety Date Fruits for Human Being as Affected by Nitrogen Fertilization Applications in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20Attalla">A.

The palms received recommended dose of mineral N only or plus different rates of organic N with or without bio fertilizer to study the effect of such treatments on date palm yield and fruit nitrate and nitrite content due to its negative influence on human, animal and environment. The obtained results clarified that all used treatments of organic and bio fertilizers were effective in improving date palm yield and decreased fruit content of NO2 and NO3 in comparison with 100 % mineral N. It was also noticed that combined treatments of 50 % mineral N + 50 % organic manure with bio fertilizer is the superior treatments for increasing the values of yield and decreasing its content of NO2 and NO3. Hence, it could be concluded that, minimizing the use of chemical nitrogen fertilizer to half of recommended dose through addition of 50 % mineral N + 50 % organic manure with bio fertilizer and also, the utilization of organic and bio fertilizers is considered as a promising alternative for chemical fertilizers to avoid pollution and reduce the costs of mineral fertilizers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20and%20bio%20fertilizers" title="organic and bio fertilizers">organic and bio fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20fertilizer" title=" mineral fertilizer"> mineral fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate" title=" nitrate"> nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrite" title=" nitrite"> nitrite</a>, <a href="https://publications.waset.org/abstracts/search?q=zaghloul%20date%20palm%20cv" title=" zaghloul date palm cv"> zaghloul date palm cv</a> </p> <a href="https://publications.waset.org/abstracts/35352/safety-date-fruits-for-human-being-as-affected-by-nitrogen-fertilization-applications-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">449</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">817</span> Evaluation of PTFE Composites with Mineral Tailing Considering Friction, Wear and Cost</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ant%C3%B4nio%20P.%20de%20Ara%C3%BAjo%20Neto">Antônio P. de Araújo Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruy%20D.%20A.%20da%20Silva%20Neto"> Ruy D.

Here, mineral oil was used in the fungal formulation to control <em>Aedes aegypti</em> larvae. 1%, 0.5% or 0.1% mineral oil-in-water solutions were used to evaluate mineral oil toxicity for mosquito larvae. In the oil toxicity test, 0.1% mineral oil solution reduced only 4.5% larval survival; accordingly, this concentration was chosen for fungal oil-in-water formulations. Aqueous suspensions were prepared using 0.01% Tween 80<sup>®</sup> in sterile dechlorinated water. <em>A. aegypti</em> larvae (L<sub>2</sub>) were exposed in aqueous suspensions or mineral oil-in-water fungal formulations at 1×107 propagules mL<sup>-1</sup>; the survival rate (assessed daily, for 7 days) and the median survival time (S<sub>50</sub>) were calculated. Seven days after the treatment, mosquito larvae survival rates were 8.56%, 16.22%, 58%, and 42.56% after exposure to oil-in-water blastospores, oil-in-water conidia, blastospores aqueous suspension and conidia aqueous suspension (respectively). Larvae exposed to 0.01% Tween 80<sup>®</sup> had 100% survival rate and the ones treated with 0.1% mineral oil-in-water had 95.11% survival rate. Larvae treated with conidia (regardless the presence of oil) or treated with blastospores formulation had survival median time (S<sub>50</sub>) ranging from one to two days. S<sub>50</sub> was not determined (ND) when larvae were exposed to blastospores aqueous suspension, 0.01% Tween 80<sup>®</sup> (aqueous control) or 0.1% mineral oil-in-water formulation (oil control). <em>B. bassiana</em> conidia and blastospores (mineral oil-in-water formulated or suspended in water) had potential to control <em>A. aegypti</em> mosquito larvae, despite mineral oil-in-water formulation yielded better results in comparison to aqueous suspensions.

Three groups of the treatment (A, B and C) with different regime of irrigation were prepared. The soil water content was maintained at 70 % of soil water holding capacity in group A, at 40 % in group B. In group C, soil water regime was maintained in the range of wilting point. Each group of the experiment was divided into three variants (A1 = B1, C1; A2 = B2, C2 etc.) with three repetitions: Variants A1 (B1, C1) were controls without addition of another fertilizer. Variants A2 (B2, C2) were fertilized with mineral nitrogen fertilizer DAM 390 (0.140 Mg of N per ha) and variants A3 (B3, C3) contained 45 g of Cp per a pot. The significant differences (ANOVA, P<0.05) in the leaching of mineral nitrogen and values of saturated hydraulic conductivity (Ksat) were found. The highest values of Ksat were found in variants (within each group) with addition of compost (A3, B3, C3). Conversely, the lowest values of Ksat were found in variants with addition of mineral nitrogen. Low values of Ksat indicate an increased level of hydrophobicity in individual groups of the experiment. Moreover, all variants with compost addition showed lower amount of mineral nitrogen leaching and high level of microbial activity than variants without. This decrease of mineral nitrogen leaching was about 200 % in comparison with the control variant and about 300 % with variant, where mineral nitrogen was added. Based on these results, we can conclude that changes of soil water content directly have impact on microbial activity, soil hydrophobicity and loss of mineral nitrogen from the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought" title="drought">drought</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20activity" title=" microbial activity"> microbial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20nitrogen" title=" mineral nitrogen"> mineral nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20hydrophobicity" title=" soil hydrophobicity"> soil hydrophobicity</a> </p> <a href="https://publications.waset.org/abstracts/7657/effects-of-drought-on-microbial-activity-in-rhizosphere-soil-hydrophobicity-and-leaching-of-mineral-nitrogen-from-arable-soil-depending-on-method-of-fertilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7657.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">383</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">814</span> The Role of Ionic Strength and Mineral Size to Zeta Potential for the Adhesion of P. putida to Mineral Surfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fathiah%20Mohamed%20Zuki">Fathiah Mohamed Zuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20George%20Edyvean"> Robert George Edyvean</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrostatic interaction energy (∆EEDL) is a part of the Extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory, which, together with van der Waals (∆EVDW) and acid base (∆EAB) interaction energies, has been extensively used to investigate the initial adhesion of bacteria to surfaces. Electrostatic or electrical double layer interaction energy is considerably affected by surface potential, however it cannot be determined experimentally and is usually replaced by zeta (ζ) potential via electrophoretic mobility. This paper focuses on the effect of ionic concentration as a function of pH and the effect of mineral grain size on ζ potential. It was found that both ionic strength and mineral grain size play a major role in determining the value of ζ potential for the adhesion of P. putida to hematite and quartz surfaces. Higher ζ potential values lead to higher electrostatic interaction energies and eventually to higher total XDLVO interaction energy resulting in bacterial repulsion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=XDLVO" title="XDLVO">XDLVO</a>, <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20interaction%20energy" title=" electrostatic interaction energy"> electrostatic interaction energy</a>, <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title=" zeta potential"> zeta potential</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20putida" title=" P. putida"> P. putida</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral" title=" mineral "> mineral </a> </p> <a href="https://publications.waset.org/abstracts/24721/the-role-of-ionic-strength-and-mineral-size-to-zeta-potential-for-the-adhesion-of-p-putida-to-mineral-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24721.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">446</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">813</span> New Off-Line SPE-GC-MS/MS Method for Determination of Mineral Oil Saturated Hydrocarbons/Mineral Oil Hydrocarbons in Animal Feed, Foods, Infant Formula and Vegetable Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ovanes%20Chakoyan">Ovanes Chakoyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> MOH (mineral oil hydrocarbons), which consist of mineral oil saturated hydrocarbons(MOSH) and mineral oil aromatic hydrocarbons(MOAH), are present in various products such as vegetable oils, animal feed, foods, and infant formula. Contamination of foods with mineral oil hydrocarbons, particularly mineral oil aromatic hydrocarbons(MOAH), exhibiting carcinogenic, mutagenic, and hormone-disruptive effects. Identifying toxic substances among the many thousands comprising mineral oils in food samples is a difficult analytical challenge. A method based on an offline-solid phase extraction approach coupled with gas chromatography-triple quadrupole(GC-MS/MS) was developed for the determination of MOSH/MOAH in various products such as vegetable oils, animal feed, foods, and infant formula. A glass solid phase extraction cartridge loaded with 7 g of activated silica gel impregnated with 10 % silver nitrate for removal of olefins and lipids. The MOSH/MOAH fractions were eluated with hexane and hexane: dichloromethane : toluene, respectively. Each eluate was concentrated to 50 µl in toluene and injected on splitless mode into GC-MS/MS. Accuracy of the method was estimated as measurement of recovery of spiked oil samples at 2.0, 15.0, and 30.0 mg kg -1, and recoveries varied from 85 to 105 %. The method was applied to the different types of samples (sunflower meal, chocolate ships, santa milk chocolate, biscuits, infant milk, cornflakes, refined sunflower oil, crude sunflower oil), detecting MOSH up to 56 mg/kg and MOAH up to 5 mg/kg.

Due to the benefits of permanent storage and abundant mineral resources, mineral carbonation (MC) is one of the most effective strategies for sequestering CO₂. The combination of mineral processing for primary metal recovery and mineral carbonation for carbon sequestration is an emerging field of study with the potential to minimize capital costs. A detailed study of low-pressures–solid carbonation of ultramafic tailings in a dry environment has been accomplished. In order to track the changing structure of serpentine minerals and their reactivity as a function of temperature (300-900 ᵒC), CO₂ partial pressure (25-90 mol %), and thermal preconditioning, thermogravimetry has been utilized. The incongruent CO₂ van der Waals molecular diameters with the octahedral-tetrahedral lattice constants of serpentine were used to explain the mild carbonation reactivity. Serpentine requires additional thermal-treatment to remove hydroxyl groups, resulting in the chemical transformation to pseudo-forsterite, which is a mineral composed of isolated SiO₄ tetrahedra linked by octahedrally coordinated magnesium ions. The heating treatment above 850 ᵒC is adequate to remove chemically bound water from the lattice. Particles with a diameter < 34 (μm) are desirable, and thermally treated serpentine at 850 ᵒC for 2.30 hours reached 65% CO₂ storage capacity. The decrease in particle size, increase in temperature, and magnetic separation can dramatically enhance carbonation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20size" title="particle size">particle size</a>, <a href="https://publications.waset.org/abstracts/search?q=thermogravimetry" title=" thermogravimetry"> thermogravimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal-treatment" title=" thermal-treatment"> thermal-treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=serpentine" title=" serpentine"> serpentine</a> </p> <a href="https://publications.waset.org/abstracts/162718/development-of-mineral-carbonation-process-from-ultramafic-tailings-enhancing-the-reactivity-of-feedstocks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162718.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">89</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">811</span> Development and Management of Integrated Mineral Resource Policy for Environmental Sustainability: The Mindanao Experience, the Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davidson%20E.%20Egirani">Davidson E.

The paper would proffer solutions via the development and management of integrated mineral resource framework. This is by interfacing the views of government, operating mining companies and the mining host communities. The project methods involved the desktop review of existing local, regional, national environmental and mining legislation. This was followed up with visits to mining sites and discussions were held with stakeholders in the mineral sector. The findings from a 2-year investigation would reveal lack of information, education, and communication campaign by stakeholders on environmental, health, political, and social issues in the mining industry. Small-scale miners lack the professional muscles for a balance shift of emphasis to sustainable and responsible mining to avoid environmental degradation and human health effect. Therefore, there is a need to balance ecological requirements, sustainability of the environment and development of mineral resources. This paper would provide an environmentally friendly mineral resource development framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20requirements" title="ecological requirements">ecological requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20degradation" title=" environmental degradation"> environmental degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20health" title=" human health"> human health</a>, <a href="https://publications.waset.org/abstracts/search?q=mining%20legislation" title=" mining legislation"> mining legislation</a>, <a href="https://publications.waset.org/abstracts/search?q=responsible%20mining" title=" responsible mining"> responsible mining</a> </p> <a href="https://publications.waset.org/abstracts/99356/development-and-management-of-integrated-mineral-resource-policy-for-environmental-sustainability-the-mindanao-experience-the-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99356.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">131</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">810</span> Potential of Mineral Composition Reconstruction for Monitoring the Performance of an Iron Ore Concentration Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Sadeghi">Maryam Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude%20Bazin"> Claude Bazin</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Hodouin"> Daniel Hodouin</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Perez%20Barnuevo"> Laura Perez Barnuevo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The performance of a separation process is usually evaluated using performance indices calculated from elemental assays readily available from the chemical analysis laboratory. However, the separation process performance is essentially related to the properties of the minerals that carry the elements and not those of the elements. Since elements or metals can be carried by valuable and gangue minerals in the ore and that each mineral responds differently to a mineral processing method, the use of only elemental assays could lead to erroneous or uncertain conclusions on the process performance. This paper discusses the advantages of using performance indices calculated from minerals content, such as minerals recovery, for process performance assessments. A method is presented that uses elemental assays to estimate the minerals content of the solids in various process streams. The method combines the stoichiometric composition of the minerals and constraints of mass conservation for the minerals through the concentration process to estimate the minerals content from elemental assays. The advantage of assessing a concentration process using mineral based performance indices is illustrated for an iron ore concentration circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20reconciliation" title="data reconciliation">data reconciliation</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20ore%20concentration" title=" iron ore concentration"> iron ore concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20composition" title=" mineral composition"> mineral composition</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20performance%20assessment" title=" process performance assessment"> process performance assessment</a> </p> <a href="https://publications.waset.org/abstracts/93580/potential-of-mineral-composition-reconstruction-for-monitoring-the-performance-of-an-iron-ore-concentration-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93580.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">218</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">809</span> Effect of Mineral Admixture on Self-Healing Performance in Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Cheol%20Choi">Young-Cheol Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Won%20Yoo"> Sung-Won Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong%20Chun%20Lee"> Bong Chun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Byoungsun%20Park"> Byoungsun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Hwa%20Jung"> Sang-Hwa Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cracks in concrete commonly provide the passages of ingresses of aggressive and harmful ions into concrete inside and thus reduce the durability of concrete members. In order to solve this problem, self-healing concrete based on mineral admixture has become a major issue. Self-healing materials are those which have the ability of autonomously repairing some damages or small cracks in concrete structures. Concrete has an inherent healing potential, called natural healing, which can take place in ordinary concrete elements but its power is limited and is not predictable. The main mechanism of self-healing in cracked concrete is the continued hydration of unreacted binder and the crystallization of calcium carbonate. Some mineral admixtures have been found to promote the self-healing of cementitious materials. The aim of this study is to investigate the effect of mineral admixture on the self-healing performances of high strength concrete. The potential capability of self-healing of cementitious materials was evaluated using isothermal conduction calorimeter. The self-healing efficiencies were studied by means of water flow tests on cracked concrete specimens. The results show a different healing behaviour depending on presence of the crystalline admixture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mineral%20admixture" title="mineral admixture">mineral admixture</a>, <a href="https://publications.waset.org/abstracts/search?q=self-healing" title=" self-healing"> self-healing</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20flow%20test" title=" water flow test"> water flow test</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a> </p> <a href="https://publications.waset.org/abstracts/75654/effect-of-mineral-admixture-on-self-healing-performance-in-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75654.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">367</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">808</span> Evaluation of Bone and Body Mineral Profile in Association with Protein Content, Fat, Fat-Free, Skeletal Muscle Tissues According to Obesity Classification among Adult Men</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orkide%20Donma">Orkide Donma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20M.%20Donma"> Mustafa M. Donma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obesity is associated with increased fat mass as well as fat percentage. Minerals are the elements, which are of vital importance. In this study, the relationships between body as well as bone mineral profile and the percentage as well as mass values of fat, fat-free portion, protein, skeletal muscle were evaluated in adult men with normal body mass index (N-BMI), and those classified according to different stages of obesity. A total of 103 adult men classified into five groups participated in this study. Ages were within 19-79 years range. Groups were N-BMI (Group 1), overweight (OW) (Group 2), first level of obesity (FLO) (Group 3), second level of obesity (SLO) (Group 4) and third level of obesity (TLO) (Group 5). Anthropometric measurements were performed. BMI values were calculated. Obesity degree, total body fat mass, fat percentage, basal metabolic rate (BMR), visceral adiposity, body mineral mass, body mineral percentage, bone mineral mass, bone mineral percentage, fat-free mass, fat-free percentage, protein mass, protein percentage, skeletal muscle mass and skeletal muscle percentage were determined by TANITA body composition monitor using bioelectrical impedance analysis technology. Statistical package (SPSS) for Windows Version 16.0 was used for statistical evaluations. The values below 0.05 were accepted as statistically significant. All the groups were matched based upon age (p > 0.05). BMI values were calculated as 22.6 ± 1.7 kg/m<sup>2</sup>, 27.1 ± 1.4 kg/m<sup>2</sup>, 32.0 ± 1.2 kg/m<sup>2</sup>, 37.2 ± 1.8 kg/m<sup>2</sup>, and 47.1 ± 6.1 kg/m<sup>2</sup> for groups 1, 2, 3, 4, and 5, respectively. Visceral adiposity and BMR values were also within an increasing trend. Percentage values of mineral, protein, fat-free portion and skeletal muscle masses were decreasing going from normal to TLO. Upon evaluation of the percentages of protein, fat-free portion and skeletal muscle, statistically significant differences were noted between NW and OW as well as OW and FLO (p < 0.05). However, such differences were not observed for body and bone mineral percentages. Correlation existed between visceral adiposity and BMI was stronger than that detected between visceral adiposity and obesity degree. Correlation between visceral adiposity and BMR was significant at the 0.05 level. Visceral adiposity was not correlated with body mineral mass but correlated with bone mineral mass whereas significant negative correlations were observed with percentages of these parameters (p < 0.001). BMR was not correlated with body mineral percentage whereas a negative correlation was found between BMR and bone mineral percentage (p < 0.01). It is interesting to note that mineral percentages of both body as well as bone are highly affected by the visceral adiposity. Bone mineral percentage was also associated with BMR. From these findings, it is plausible to state that minerals are highly associated with the critical stages of obesity as prominent parameters. <p class="card-text"><strong>Keywords:</strong> <a
