The engineering industry, especially automobile, are potential users of this material. As it is known, the alloying elements modify the properties of steels and castings. Copper has been investigated as a structural modifier of nodular iron, but studies of its mechanical and tribological implications still need to be addressed for industrial use. With the aim of improving the mechanical properties of nodular iron, alloying elements (Mn, Si, and Cu) are added in order to increase their pearlite (or ferrite) structure according to the percentage of the alloying element. In this research (using induction furnace process) nodular iron with three different percentages of copper (residual, 0,5% and 1,2%) was obtained. Chemical analysis was performed by optical emission spectrometry and microstructures were characterized by Optical Microscopy (ASTM E3) and Scanning Electron Microscopy (SEM). The study of mechanical behavior was carried out in a mechanical test machine (ASTM E8) and a Pin on disk tribometer (ASTM G99) was used to assess wear resistance. It is observed that copper increases the pearlite structure improving the wear behavior; tension behavior. This improvement is observed in higher proportion with 0,5% due to the fact that too much increase of pearlite leads to ductility loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper" title="copper">copper</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nodular%20iron" title=" nodular iron"> nodular iron</a>, <a href="https://publications.waset.org/abstracts/search?q=pearlite%20structure" title=" pearlite structure"> pearlite structure</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/17527/wear-and-mechanical-properties-of-nodular-iron-modified-with-copper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">385</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">986</span> Influence of Raw Material Composition on Microstructure and Mechanical Properties of Nodular Cast Iron </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko">Alan Vaško</a>, <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Belan"> Juraj Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Hurtalov%C3%A1"> Lenka Hurtalová</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tillov%C3%A1"> Eva Tillová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate the influence of raw material composition on the microstructure, mechanical and fatigue properties and micromechanisms of failure of nodular cast iron. In order to evaluate the influence of charge composition, the structural analysis, mechanical and fatigue tests and micro fractographic analysis were carried out on specimens of ten melts with different charge compositions. The basic charge of individual melts was formed by a different ratio of pig iron and steel scrap and by different additive for regulation of chemical composition (silicon carbide or ferrosilicon). The results show differences in mechanical and fatigue properties, which are connected with the microstructure. SiC additive positively influences microstructure. Consequently, mechanical and fatigue properties of nodular cast iron are improved, especially in the melts with the higher ratio of steel scrap in the charge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nodular%20cast%20iron" title="nodular cast iron">nodular cast iron</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20carbide" title=" silicon carbide"> silicon carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/20276/influence-of-raw-material-composition-on-microstructure-and-mechanical-properties-of-nodular-cast-iron" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20276.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">582</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">985</span> Metastatic Polypoid Nodular Melanoma Management During The COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Bradu">Stefan Bradu</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Siegel"> Daniel Siegel</a>, <a href="https://publications.waset.org/abstracts/search?q=Jameson%20Loyal"> Jameson Loyal</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Leaf"> Andrea Leaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Alana%20Kurtti"> Alana Kurtti</a>, <a href="https://publications.waset.org/abstracts/search?q=Usha%20Alapati"> Usha Alapati</a>, <a href="https://publications.waset.org/abstracts/search?q=Jared%20Jagdeo"> Jared Jagdeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compared with all other variants of nodular melanoma, patients with polypoid nodular melanoma have the lowest 5-year survival rate. The pathophysiology and management of polypoid melanoma are scarcely reported in the literature. Although surgical excision is the cornerstone of melanoma management, treatment of polypoid melanoma is complicated by several negative prognostic factors, including early metastasis. This report demonstrates the successful treatment of a rapidly developing red nodular polypoid melanoma with metastasis using surgery and adjuvant nivolumab in a SARS-CoV-2-positive patient who delayed seeking care due to the COVID-19 pandemic. In addition to detailing the successful treatment approach, the immunosuppressive effects of SARS-2-CoV and its possible contribution to the rapid progression of polypoid melanoma are discussed. This case highlights the complex challenges of melanoma diagnosis and management during the COVID-19 pandemic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=covid-19" title="covid-19">covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=dermatology" title=" dermatology"> dermatology</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=melanoma" title=" melanoma"> melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=nivolumab" title=" nivolumab"> nivolumab</a> </p> <a href="https://publications.waset.org/abstracts/140542/metastatic-polypoid-nodular-melanoma-management-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140542.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">209</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">984</span> Effect of Iron Contents on Rheological Properties of Syndiotactic Polypropylene/iron Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naveed%20Ahmad">Naveed Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Farooq%20Ahmad"> Farooq Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Aal"> Abdul Aal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of iron contents on the rheological behavior of sPP/iron composites in the melt phase was investigated using a series of syndiotactic polypropylene/iron (sPP/iron) composite samples.

Lakdawala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Clustering phenomenon of pellets was observed frequently in shaft processes operating at higher temperatures. Clustering is a result of the growth of fibrous iron precipitates (iron whiskers) that become hooked to each other and finally become crystallized during the initial stages of metallization. If the pellet clustering is pronounced, sometimes leads to blocking inside the furnace and forced shutdown takes place. This work clarifies further the relation between metallic iron whisker growth and iron ore mineralogy. Various pellet sizes (6 – 12.0 & +12.0 mm) from three different ores (A, B & C) were (completely and partially) reduced at 985 <sup>o</sup>C with H<sub>2</sub>/CO gas mixture using thermos-gravimetric technique. It was found that reducibility increases by decreasing the iron ore pellet’s size. Ore (A) has the highest reducibility than ore (B) and ore (C). Increasing the iron ore pellet’s size leads to increase the probability of metallic iron whisker formation. Ore (A) has the highest tendency for metallic iron whisker formation than ore (B) and ore (C). The reduction reactions for all iron ores A, B and C are mainly controlled by diffusion reaction mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shaft%20furnace" title="shaft furnace">shaft furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster" title=" cluster"> cluster</a>, <a href="https://publications.waset.org/abstracts/search?q=metallic%20iron%20whisker" title=" metallic iron whisker"> metallic iron whisker</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralogy" title=" mineralogy"> mineralogy</a>, <a href="https://publications.waset.org/abstracts/search?q=ferrous%20metallurgy" title=" ferrous metallurgy"> ferrous metallurgy</a> </p> <a href="https://publications.waset.org/abstracts/42409/influence-of-iron-ore-mineralogy-on-cluster-formation-inside-the-shaft-furnace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42409.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">470</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">982</span> Investigation of the Fading Time Effects on Microstructure and Mechanical Properties in Vermicular Cast Iron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Ekici">Mehmet Ekici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the fading time affecting the mechanical properties and microstructures of vermicular cast iron were studied.

Its deficiency has serious health consequences and is a major public health threat worldwide. The common deficiencies in Fiji population reported are of Fe, Ca and Zn. It has also been reported that 40% of women in Fiji are iron deficient. Therefore, we have been studying the bioavailability of iron in commonly consumed Fiji foods. To study the bioavailability it is essential to assess the iron contents in raw foods. This paper reports the iron contents and its bioavailability in commonly consumed foods by multicultural population of Fiji. The food samples (rice, breads, wheat flour and breakfast cereals) were analyzed by atomic absorption spectrophotometer for total iron and its bioavailability. The white rice had the lowest total iron 0.10±0.03 mg/100g but had high bioavailability of 160.60±0.03%. The brown rice had 0.20±0.03 mg/100g total iron content but 85.00±0.03% bioavailable. The white and brown breads showed the highest iron bioavailability as 428.30±0.11 and 269.35 ±0.02%, respectively. The Weetabix and the rolled oats had the iron contents 2.89±0.27 and 1.24.±0.03 mg/100g with bioavailability of 14.19±0.04 and 12.10±0.03%, respectively. The most commonly consumed normal wheat flour had 0.65±0.00 mg/100g iron while the whole meal and the Roti flours had 2.35±0.20 and 0.62±0.17 mg/100g iron showing bioavailability of 55.38±0.05, 16.67±0.08 and 12.90±0.00%, respectively. The low bioavailability of iron in certain foods may be due to the presence of phytates/oxalates, processing/storage conditions, cooking method or interaction with other minerals present in the food samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron" title="iron">iron</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title=" bioavailability"> bioavailability</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiji%20foods" title=" Fiji foods"> Fiji foods</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro%20technique" title=" in vitro technique"> in vitro technique</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20nutrition" title=" human nutrition"> human nutrition</a> </p> <a href="https://publications.waset.org/abstracts/27271/bioavailability-of-iron-in-some-selected-fiji-foods-using-in-vitro-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27271.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">529</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">980</span> Removal of Iron (II) from Wastewater in Oil Field Using 3-(P-Methyl) Phenyl-5-Thionyl-1,2,4-Triazoline Assembled on Silver Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20M.%20S.%20Azzam">E.

The nanostructure of the prepared C1 compound was fabricated by assembling on silver nanoparticles. The UV and TEM analyses confirm the assembling of C1 compound on silver nanoparticles. The effect of C1 compound on the removal of Iron (II) from Iron contaminated samples and industrial wastewater samples (produced water from oil processing facility) were studied before and after their assembling on silver nanoparticles. The removal of Iron was studied at different concentrations of FeSO4 solution (5, 14 and 39 mg/l) and field sample concentration (661 mg/l). In addition, the removal of Iron (II) was investigated at different times. The Prepared compound and its nanostructure with AgNPs show highly efficient in removing the Iron ions. Quantum chemical descriptors using DFT was discussed. The output of the study pronounces that the C1 molecule can act as chelating agent for Iron (II). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=triazole%20derivatives" title="triazole derivatives">triazole derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20%28II%29" title=" iron (II)"> iron (II)</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20field" title=" oil field"> oil field</a> </p> <a href="https://publications.waset.org/abstracts/93747/removal-of-iron-ii-from-wastewater-in-oil-field-using-3-p-methyl-phenyl-5-thionyl-124-triazoline-assembled-on-silver-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93747.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">657</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">979</span> Synthesis and Characterization of Iron Modified Geopolymer and Its Resistance against Chloride and Sulphate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noor-ul-Amin">Noor-ul-Amin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lubna%20Nawab"> Lubna Nawab</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabiha%20Sultana"> Sabiha Sultana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Geopolymer with different silica to alumina ratio with iron have been synthesized using sodium silicate, aluminum, and iron salts as a source of silica, alumina and iron source, and sodium/potassium hydroxide as an alkaline medium. The iron source will be taken from iron (III) salts and laterite clay samples. Laterite has been used as a natural source of iron in modified geopolymer. The synthesized iron modified geopolymer was submitted to the different aggressive environment, including chloride and sulphate solutions in different concentration. Different experimental techniques, including XRF, XRD, and FTIR, were used to study the bonding nature and effect of aggressive environment on geopolymer. The major phases formed during geopolymerization are sodalite (Na₄Al₃Si₃O₁₂Cl), albite (NaAlSi₃O₈), hematite (Fe₂O₃), and chabazite as confirmed from the XRD results. The resulting geopolymer showed greater resistance to sulphate and chloride as compared to the normal geopolymer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modified%20geopolymer" title="modified geopolymer">modified geopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=laterite" title=" laterite"> laterite</a>, <a href="https://publications.waset.org/abstracts/search?q=chloride" title=" chloride"> chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate" title=" sulphate"> sulphate</a> </p> <a href="https://publications.waset.org/abstracts/130375/synthesis-and-characterization-of-iron-modified-geopolymer-and-its-resistance-against-chloride-and-sulphate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130375.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">156</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">978</span> Synthesis of Bimetallic Fe/Cu Nanoparticles with Different Copper Loading Ratios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=May%20Thant%20Zin">May Thant Zin</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephine%20Borja"> Josephine Borja</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirofumi%20Hinode"> Hirofumi Hinode</a>, <a href="https://publications.waset.org/abstracts/search?q=Winarto%20Kurniawan"> Winarto Kurniawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanotechnology has multiple and enormous advantages for all application. Therefore, this research is carried out to synthesize and characterize bimetallic iron with copper nano-particles. After synthesizing nano zero valent iron by reduction of ferric chloride by sodium borohydride under nitrogen purging environment, bimetallic iron with copper nanoparticles are synthesized by varying different loads of copper chloride. Due to different standard potential (E0) values of copper and iron, copper is coupled with iron at (Cu to Fe ratio of 1:5, 1:6.7, 1:10, 1:20). It is found that the resulted bimetallic Fe/Cu nanoparticles are composing phases of iron and copper. According to the diffraction patterns indicating the state of chemical combination of the bimetallic nanoparticles, the particles are well-combined and crystalline sizes are less than 1000 Ao (or 100 nm). Specifically, particle sizes of synthesized bimetallic Fe/Cu nanoparticles are ranging from 44.583 nm to 85.149 nm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/3276/synthesis-of-bimetallic-fecu-nanoparticles-with-different-copper-loading-ratios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3276.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">445</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">977</span> Solid Oral Leiomyoma: Clinical Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hurtado%20Zu%C3%B1iga%20Yonel%20Marcos">Hurtado Zuñiga Yonel Marcos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferreira%20Joao%20Tiago"> Ferreira Joao Tiago</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Leiomyoma is a benign smooth muscle tumor. It is predominantly found between 40-49 years with a small prevalence in men. It is commonly found in the uterus, stomach, and in areas with smooth muscle. It presents as nodular, solitary, variable size, slow growing, and asymptomatic. It is classified into solid, vascular, and epithelioid leiomyoma. Vascular leiomyoma is the most common in the oral cavity. Oral leiomyomas are very rare because a smooth muscle in the oral cavity isn’t common. The most frequent areas of this pathologyaretongue, lip, buccal mucosa, and palate. It may be derived from the vascular walls or excretory ducts of the salivary glands. The diagnosis is made by histologically analysis. The treatment of choice is complete excision. Recurrence is rare. Objective: To report the case of a solid leiomyoma on the dorsum of the tongue and review the literature. Case description: A 78-year-old female patient presented a nodular (ovoid) elevation of 8x6mm, brownish color, with irregular limits and firm consistency located in the dorsal part of the tongue with slight symptoms. An excisional biopsy was performed, photographic record, and 3 weeks post-surgical follow-up. Result: The surgical specimen was submitted to an anatomopathological analysis, resulting in a benign nodule with defined limits compatible with solid leiomyoma of the tongue. Discussion: It is a pathology that presents in a solitary, nodular, well-defined, asymptomatic form; in the oral cavity, leiomyomas are found in the tongue, lip, buccal mucosa, and palate; as in our patient, it was nodular and, in the tongue, with a difference only in the symptomatology. The most prevalent age is 40-49 years and with small predominance in men, unlike our female patient with 78 years. Conclusions: Oral leiomyoma is a rare benign lesion that presents as a solitary nodular nodule; for its diagnosis, an anatomopathological analysis should be performed, and the treatment of choice is total excision with little recurrence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tongue" title="tongue">tongue</a>, <a href="https://publications.waset.org/abstracts/search?q=bening%20tumor" title=" bening tumor"> bening tumor</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20leiomyoma" title=" oral leiomyoma"> oral leiomyoma</a>, <a href="https://publications.waset.org/abstracts/search?q=leiomyoma" title=" leiomyoma"> leiomyoma</a> </p> <a href="https://publications.waset.org/abstracts/141465/solid-oral-leiomyoma-clinical-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141465.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">217</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">976</span> Utilization of Sorghum and White Bean Flour for the Production of Gluten Free and Iron Rich Cookies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahra%20Elobeid">Tahra Elobeid</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmerich%20Berghofer"> Emmerich Berghofer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to find innovative approaches for the production of iron rich foods using natural iron sources. The vehicle used for fortification was sorghum whereas the iron fortificant was white bean. Fortified sorghum cookies were produced from five different mixtures; iron content, iron bioavailability, cookie texture and acceptability were measured. Cookies were prepared from the three fortified flours; 90% sorghum + 10% white bean (S9WB1), 75% sorghum + 25% white bean (S3WB1), 50% sorghum + 50% white bean (S1WB1) and 100% sorghum and 100% white bean. The functional properties gave good results in all the formulations. Statistical analysis of the iron content in the five different cookies showed that there was significant difference at the 95% confidence level (ANOVA). The iron content in all the recipes including the 100% sorghum improved, the increase ranging from 112% in 100% sorghum cookies to 476% in 100% white bean cookies. This shows that the increase in the amount of white bean used for fortification leads to the improvement of the iron content of cookies. The bioavailability of iron ranged from 21.3% in 100% sorghum to 28.6% in 100% white bean cookies. In the 100% sorghum cookies the iron bioavailability increased with reference to raw sorghum due to the addition of eggs. Bioavailability of iron in raw sorghum is 16.2%, therefore the percentage increase ranged from 5.1% to 28.6%. The cookies prepared from 10% white bean (S9WB1) scored the lowest 3.7 in terms of acceptability. They were the least preferred due to their somewhat soft texture. The 30% white bean cookies (S3WB1) gave results comparable to the 50% (S1WB1) and 100% white bean cookies. Cookies prepared with high percentage of white bean (50% and 100% white bean) gave the best results. Therefore cookie formulations from sorghum and white bean are successful in improving the iron status of anaemic individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sorghum" title="sorghum">sorghum</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20bean" title=" white bean"> white bean</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20content" title=" iron content"> iron content</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailable%20iron" title=" bioavailable iron"> bioavailable iron</a>, <a href="https://publications.waset.org/abstracts/search?q=cookies" title=" cookies"> cookies</a> </p> <a href="https://publications.waset.org/abstracts/18687/utilization-of-sorghum-and-white-bean-flour-for-the-production-of-gluten-free-and-iron-rich-cookies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18687.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">415</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">975</span> Prevalence of Overweight and Obesity in Iron-Deficient Iranian Teenagers Girls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eftekhari%20M.%20H.">Eftekhari M.

Objective: we aimed to investigate the association between iron deficiency and weight status (measured as BMI) among a reprehensive sample of teenage girls. Methods: A cross-sectional study was performed in a region of southern I.R.Iran. One hundred eighty-seven iron-deficient participants (aged between 11 to 14) were selected by systematic random sampling among all students in grades 1 to 3 from high schools for girls. We assayed hemoglobin, hematocrit, serum ferritin, iron and total iron binding capacity and measured weight and height. Body mass index was calculated according to age and gender-specific BMI growth charts for children 2 to 20 years of age. Results: 13% were at risk for being overweight and 8.3% were overweight. The severity of iron deficiency increased as BMI increased from normal to at risk for overweight and overweight. Iron deficiency anemia was most prevalent among overweight adolescents than at risk for overweight and normal weight adolescents (28%, 18%, and 13%, respectively). Conclusions: The results of this study showed an inverse association of BMI with serum ferritin. Overweight adolescents demonstrated an increased prevalence of anemia. Because of the potentially harmful effects of iron deficiency, obese adolescents should be routinely screened and treated as necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescent" title="adolescent">adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=over%20weight" title=" over weight"> over weight</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20deficiency" title=" iron deficiency"> iron deficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/154590/prevalence-of-overweight-and-obesity-in-iron-deficient-iranian-teenagers-girls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154590.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">140</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">974</span> Prevalence and Determinants of Iron Deficiency Anaemia in Pregnant Xhosa Women </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Abiodun">A.

Methods: This cross-sectional study was conducted among pregnant Xhosa women from rural areas of Mthatha, South Africa, according to socio-demographic, geophagia, haematologic and iron metabolism profiles using univariate and multivariate analyses. Anaemia was defined by haemoglobin <11 g/dL and iron deficiency was defined by serum ferritin < 12 ug/L. Results: Out of 210 pregnant women (mean age =23±5.3 for geophagic and 25.6±5.3 for non-geophagic), 51.4% (n = 108) had iron deficiency anaemia (50.9% geophagic and 49.1% non-geophagic). After adjusting for confounders, only geophagia (OR=2.1 95% CI 1.1-4.2; P=0.029) and mean corpuscular haemoglobin concentration categories (< 30.5 g/dL with OR=16.6 95% CI 6.8-40.2; P < 0.0001; 30.5-31.5 g/dL with OR=2.9 95% CI 1.4-6.1; P=0.006; and ≥ 31.5 g/dL with OR=1) were identified as the most important significant and independent determinants of iron deficiency anaemia. Conclusion: The study results point to the potential harm geophagia can cause in pregnant women. The prevalence of iron deficiency anaemia is unacceptably high. Geophagic behaviour, low MCHC presented as particular risk factors of iron deficiency anaemia in this study. Education and counselling about appropriate diet during pregnancy and prevention of geophagic behaviour (and health consequences) are needed among pregnant Xhosa women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geophagia" title="geophagia">geophagia</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20deficiency%20anaemia" title=" iron deficiency anaemia"> iron deficiency anaemia</a>, <a href="https://publications.waset.org/abstracts/search?q=Xhosa" title=" Xhosa"> Xhosa</a> </p> <a href="https://publications.waset.org/abstracts/62093/prevalence-and-determinants-of-iron-deficiency-anaemia-in-pregnant-xhosa-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62093.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">377</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">973</span> Effect of Austenitization Temperature on Wear Behavior of Carbidic Austempered Ductile Iron (CADI)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20Likhite">Ajay Likhite</a>, <a href="https://publications.waset.org/abstracts/search?q=Prashant%20Parhad"> Prashant Parhad</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20R.%20Peshwe"> D.

Also, it is characterized by an increase in total iron binding capacity (TIBC). Red blood cells become microctytic and hypochromic due to a decrease in iron content. This study was conducted in the north west of Libya and included 210 women in childbearing age (18-45 years) who were visiting women clinic. After filling the questionnaire, blood samples were taken and analyzed for hematological and biochemical profiles. Biochemical tests included measurement of serum iron, ferritin, and total iron binding capacity (TIBC). Among the total sample (210 women), there were 87 (41.42%) pregnant and 123 (58.57%) non-pregnant women (includes married and single). Pregnant women (87) were classified according to the gestational age into first, second, and third trimesters. The means of biochemical and hematological parameters in the studied samples were: Hb = 10.37± 2.02 g/dl, RBC = 3.78± 1.037 m/m3, serum iron 61.86± 40.28 µg/dl, and TIBC = 386.01 ± 94.91 µg/dl. In this study, we considered that any women have hemoglobin below 11.5 g/dl is anemic. 89.1%, 69.5%, and 47.8% of pregnant women who belong to third trimester had low (below normal value) Hb, serum iron, and ferritin, i.e. iron deficiency anemia was more common in third trimester among the first and the second trimesters. Third trimester pregnant women also had high TIBC more than first and second trimesters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=red%20blood%20cells" title="red blood cells">red blood cells</a>, <a href="https://publications.waset.org/abstracts/search?q=hemoglobin" title=" hemoglobin"> hemoglobin</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20iron%20binding%20capacity" title=" total iron binding capacity"> total iron binding capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=ferritin" title=" ferritin"> ferritin</a> </p> <a href="https://publications.waset.org/abstracts/6027/prevalence-of-anemia-and-iron-deficiency-in-women-of-childbearing-age-in-the-north-west-of-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6027.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">531</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">970</span> Effect of Blast Furnace Iron Slag on the Mechanical Performance of Hot Mix Asphalt (HMA)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayman%20M.%20Othman">Ayman M.

The mechanical performance was evaluated based on various mechanical properties that include; Marshall/stiffness, indirect tensile strength and unconfined compressive strength. The effect of iron slag content on the mechanical properties of the mixtures was also investigated. Four HMA with various iron slag contents, namely; 0%, 5%, 10% and 15% by weight of total mixture were studied. Laboratory testing has revealed an enhancement in the compressive strength of HMA when iron slag was used. Within the tested range of iron slag content, a considerable increase in the compressive strength of the mixtures was observed with the increase of slag content. No significant improvement on Marshall/stiffness and indirect tensile strength of the mixtures was observed when slag was used. Even so, blast furnace iron slag can still be used in asphalt paving for environmental advantages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace%20iron%20slag" title="blast furnace iron slag">blast furnace iron slag</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=HMA" title=" HMA"> HMA</a>, <a href="https://publications.waset.org/abstracts/search?q=indirect%20tensile%20strength" title=" indirect tensile strength"> indirect tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=marshall%2Fstiffness" title=" marshall/stiffness"> marshall/stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20performance" title=" mechanical performance"> mechanical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/38784/effect-of-blast-furnace-iron-slag-on-the-mechanical-performance-of-hot-mix-asphalt-hma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38784.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">438</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">969</span> Influence of Pouring Temperature on the Formation of Spheroidal and Lamellar Graphite in Cast Iron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Ekici">Mehmet Ekici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this research is to investigate the effect of pouring temperature on the microstructure of the cast iron. The pattern was designed with 300 mm of width, and the thickness variations are 1.25 mm and poured at five different temperatures; 1300, 1325, 1350, 1375 and 1400°C. Several cast irons, prepared with different chemical compositions and microstructures (three lamellar and three spheroidal structures) have been examined by extensive mechanical testing and optical microscopy. The fluidity of spheroidal and lamellar graphite in cast iron increases with the pouring temperature. The numbers of nodules were decreased by increasing pouring temperature for spheroidal structures. Whereas, the numbers of flakes of lamellar structures changed by both pouring temperature and chemical composition. In general, with increasing pouring temperature, the amount of pearlite in the internal structure of both lamellar and spheroidal graphite cast iron materials were increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spheroidal%20graphite%20cast%20iron" title="spheroidal graphite cast iron">spheroidal graphite cast iron</a>, <a href="https://publications.waset.org/abstracts/search?q=lamellar%20graphite%20in%20cast%20iron" title=" lamellar graphite in cast iron"> lamellar graphite in cast iron</a>, <a href="https://publications.waset.org/abstracts/search?q=pouring%20temperature" title=" pouring temperature"> pouring temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20test%20and%20impact%20test" title=" tensile test and impact test"> tensile test and impact test</a> </p> <a href="https://publications.waset.org/abstracts/61555/influence-of-pouring-temperature-on-the-formation-of-spheroidal-and-lamellar-graphite-in-cast-iron" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61555.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">968</span> Iron Extraction from Bog Iron Ore in Early French Colonial America</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yves%20Monette">Yves Monette</a>, <a href="https://publications.waset.org/abstracts/search?q=Brad%20Loewen"> Brad Loewen</a>, <a href="https://publications.waset.org/abstracts/search?q=Louise%20Pothier"> Louise Pothier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study explores the first bog iron ore extraction activities which took place in colonial New France. Archaeological excavations carried on the founding site of Montreal in the last ten years have revealed the remains of Fort Ville-Marie erected in 1642. In a level related to the fort occupation between 1660 and 1680, kilos of scories, a dozen of half-finished iron artefacts and a light yellow clayey ore material have recovered that point to extractive metallurgy activities at the fort. Examples of scories, artefacts and of a possible bog iron ore were submitted to SEM-EDS analysis. The results clearly indicate that iron was extracted from local limonite ores in a bloomery. We discovered that the gangue material could be traced from the ore to the scories. However, some lime silicates and some accessory minerals found in the scories, like barite and celestine for example, were absent from the ore but present in dolomite fragments found in the same archaeological context. The tracing of accessory minerals suggests that the ironmaster introduced a lime flux in the bloomery charge to maximize the separation of the iron ore. Before the introduction of the blast furnace in Western Europe during the first half of the 18th Century, the use of fluxes in iron bloomery was not a common practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bog%20iron%20ore" title="bog iron ore">bog iron ore</a>, <a href="https://publications.waset.org/abstracts/search?q=extractive%20metallurgy" title=" extractive metallurgy"> extractive metallurgy</a>, <a href="https://publications.waset.org/abstracts/search?q=French%20colonial%20America" title=" French colonial America"> French colonial America</a>, <a href="https://publications.waset.org/abstracts/search?q=Montreal" title=" Montreal"> Montreal</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscopy%20%28SEM%29" title=" scanning electron microscopy (SEM)"> scanning electron microscopy (SEM)</a> </p> <a href="https://publications.waset.org/abstracts/80232/iron-extraction-from-bog-iron-ore-in-early-french-colonial-america" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80232.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">354</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">967</span> Synthesis of Nano Iron Copper Core-Shell by Using K-M Reactor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ahmed%20AbdelKawy">Mohamed Ahmed AbdelKawy</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20El-Shazly"> A.

The reaction between nano-pure iron with copper sulphate pentahydrate (CuSO4.5H2O) beside NaCMC as a stabilizer at K-M reactor gives many advantages in comparison with the traditional chemical method for production of nano iron-Copper core-shell in batch reactor. Many factors were investigated for its effect on the process performance such as initial concentrations of nano iron and copper sulphate pentahydrate solution. Different techniques were used for investigation and characterization of the produced nano iron particles such as SEM, XRD, UV-Vis, XPS, TEM and PSD. The produced Nano iron-copper core-shell particle using micro mixer showed better characteristics than those produced using batch reactor in different aspects such as homogeneity of the produced particles, particle size distribution and size, as core diameter 10nm particle size were obtained. The results showed that 10 nm core diameter were obtained using Micro mixer as compared to 80 nm core diameter in one-fourth the time required by using traditional batch reactor and high thickness of copper shell and good stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20iron" title="nano iron">nano iron</a>, <a href="https://publications.waset.org/abstracts/search?q=core-shell" title=" core-shell"> core-shell</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction%20reaction" title=" reduction reaction"> reduction reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=K-M%20reactor" title=" K-M reactor "> K-M reactor </a> </p> <a href="https://publications.waset.org/abstracts/39924/synthesis-of-nano-iron-copper-core-shell-by-using-k-m-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39924.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">309</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">966</span> Enhanced Iron Accumulation in Chickpea Though Expression of Iron-Regulated Transport and Ferritin Genes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20M.%20L.%20Hoang">T.

Currently, two major approaches namely iron supplementation and food fortification have been used to combat this issue. These measures, however, are limited by the economic status of the targeted demographics. Iron biofortification through genetic modification to enhance the inherent iron content and bioavailability of crops has been employed recently. Several important crops such as rice, wheat, and banana were reported successfully improved iron content via this method, but there is no known study in legumes. Chickpea (Cicer arietinum) is an important leguminous crop that is widely consumed, particularly in India where iron deficiency anaemia is prevalent. Chickpea is also an ideal pulse in the formulation of complementary food between pulses and cereals to improve micronutrient contents. This project aims at generating enhanced ion accumulation and bioavailability chickpea through the exogenous expression of genes related to iron transport and iron homeostasis in chickpea plants. Iron-Regulated Transport (IRT) and Ferritin genes in combination were transformed into chickpea half-embryonic axis by agrobacterium–mediated transformation. Transgenic independent event was confirmed by Southern Blot analysis. T3 leaves and seeds of transgenic chickpea were assessed for iron contents using LA-ICP-MS (Laser Ablation – Inductively Coupled Plasma Mass Spectrometry) and ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry). The correlation between transgene expression levels and iron content in T3 plants and seeds was assessed using qPCR. Results show that iron content in transgenic chickpea expressing the above genes significantly increased compared to that in non-transgenic controls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron%20biofortification" title="iron biofortification">iron biofortification</a>, <a href="https://publications.waset.org/abstracts/search?q=chickpea" title=" chickpea"> chickpea</a>, <a href="https://publications.waset.org/abstracts/search?q=IRT" title=" IRT"> IRT</a>, <a href="https://publications.waset.org/abstracts/search?q=ferritin" title=" ferritin"> ferritin</a>, <a href="https://publications.waset.org/abstracts/search?q=Agrobacterium-mediated%20transformation" title=" Agrobacterium-mediated transformation"> Agrobacterium-mediated transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-ICP-MS" title=" LA-ICP-MS"> LA-ICP-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=ICP-OES" title=" ICP-OES"> ICP-OES</a> </p> <a href="https://publications.waset.org/abstracts/74885/enhanced-iron-accumulation-in-chickpea-though-expression-of-iron-regulated-transport-and-ferritin-genes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74885.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">441</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">965</span> A Comparison of the Adsorption Mechanism of Arsenic on Iron-Modified Nanoclays</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Leo%20L.%20Dela%20Cruz">Michael Leo L.

A comparative study on the adsorption mechanism of arsenic on iron modified nanoclays was undertaken. Iron intercalated montmorillonite (Fe-MMT) and montmorillonite supported zero-valent iron (ZVI-MMT) were the adsorbents investigated in this study. Fe-MMT was produced through ion-exchange by replacing the sodium intercalated ions in montmorillonite with iron (III) ions. The iron (III) in Fe-MMT was later reduced to zero valent iron producing ZVI-MMT. Adsorption study was performed by batch technique. Obtained data were fitted to intra-particle diffusion, pseudo-first order, and pseudo-second-order models and the Elovich equation to determine the kinetics of adsorption. The adsorption of arsenic on Fe-MMT followed the intra-particle diffusion model with intra-particle rate constant of 0.27 mg/g-min0.5. Arsenic was found to be chemically bound on ZVI-MMT as suggested by the pseudo-second order and Elovich equation. The derived pseudo-second order rate constant was 0.0027 g/mg-min with initial adsorption rate computed from the Elovich equation was 113 mg/g-min. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20mechanism" title="adsorption mechanism">adsorption mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic" title=" arsenic"> arsenic</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20valent%20iron" title=" zero valent iron"> zero valent iron</a> </p> <a href="https://publications.waset.org/abstracts/9758/a-comparison-of-the-adsorption-mechanism-of-arsenic-on-iron-modified-nanoclays" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9758.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">415</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">964</span> Wasteless Solid-Phase Method for Conversion of Iron Ores Contaminated with Silicon and Phosphorus Compounds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%D0%90.%20V.%20Panko">А.

The fertilizer is composed of iron oxides as a source of iron and compost as humic substance (HS) source, which can serve as chelator of iron to stabilize the dissolved species under oxic seawater condition. However, elution mechanisms of iron from iron oxide surfaces have not sufficiently elucidated. In particular, roles of microbial activities in the elution of iron from the fertilizer are not sufficiently understood. In the present study, a fertilizer (iron oxide/compost = 1/1, v/v) was incubated in a water tank at Mashike coast, Hokkaido Japan. Microorganisms in the 6-month fertilizer were isolated and identified as Exiguobacterium oxidotolerans sp. (T-2-2). The identified bacteria were inoculated to perform iron elution test in a postgate B medium, prepared in artificial seawater. Hematite was used as a model iron oxide and anthraquinone-2,7-disolfonate (AQDS) as a model for HSs. The elution test performed in presence and absence of bacteria inoculation. ICP-AES was used to analyze total iron and a colorimetric technique using ferrozine employed for the determination of ferrous ion. During the incubation period, sample contained hematite and T-2-2 in both presence and absence of AQDS continuously showed the iron elution and reached at the highest concentration after 9 days of incubation and then slightly decrease to stabilize within 20 days. Comparison to the sample without T-2-2, trace amount of iron was observed, suggesting that iron elution to seawater can be attributed to bacterial activities. The levels of total organic carbon (TOC) in the culture solution with hematite decreased. This may be to the adsorption of organic compound, AQDS, to hematite surfaces. The decrease in UV-vis absorption of AQDS in the culture solution also support the results of TOC that AQDS was adsorbed to hematite surfaces. AQDS can enhance the iron elution, while the adsorption of organic matter suppresses the iron elution from hematite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthraquinone-2" title="anthraquinone-2">anthraquinone-2</a>, <a href="https://publications.waset.org/abstracts/search?q=7-disolfonate" title=" 7-disolfonate"> 7-disolfonate</a>, <a href="https://publications.waset.org/abstracts/search?q=barren%20ground" title=" barren ground"> barren ground</a>, <a href="https://publications.waset.org/abstracts/search?q=E.oxidotolerans%20sp." title=" E.oxidotolerans sp."> E.oxidotolerans sp.</a>, <a href="https://publications.waset.org/abstracts/search?q=hematite" title=" hematite"> hematite</a>, <a href="https://publications.waset.org/abstracts/search?q=humic%20substances" title=" humic substances"> humic substances</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20elution" title=" iron elution"> iron elution</a> </p> <a href="https://publications.waset.org/abstracts/35230/microbial-effects-of-iron-elution-from-hematite-into-seawater-mediated-via-dissolved-organic-matter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35230.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">379</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">961</span> Deficiencies in Vitamin A and Iron Supply Potential of Selected Indigenous Complementary Foods of Infants in Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Richard%20Kajjura">Richard Kajjura</a>, <a href="https://publications.waset.org/abstracts/search?q=Joyce%20Kikafunda"> Joyce Kikafunda</a>, <a href="https://publications.waset.org/abstracts/search?q=Roger%20Whitehead"> Roger Whitehead</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Indigenous complementary recipes for children (6-23 months) are bulky and inextricably linked. The potential contribution of indigenous complementary foods to infant’s vitamin A and iron needs is not well investigated in Uganda. Less is known whether children in Uganda are living with or without adequate supply of vitamin A and iron nutrients. In this study, vitamin A and iron contents were assessed in the complementary foods fed to infants aged 6-11 months in a Peri-urban setting in Kampala District in Central Uganda. Objective: Assessment of vitamin A and iron contents of indigenous complementary foods of children as fed and associated demographic factor. Method: In a cross sectional study design, one hundred and three (153) households with children aged 6-11 months were randomly selected to participate in the assessment. Complementary food samples were collected from the children’s mothers/caretakers at the time of feeding the child. The mothers’ socio-demographic characteristics of age, education, marital status, occupation and sex collected a semi-qualitative questionnaire. The Vitamin A and iron contents in the complementary foods were analyzed using a UV/VIS spectrophotometer for vitamin A and Atomic Absorption spectrophotometer for iron samples. The data was analyzed using Gene-stat software program. Results: The mean vitamin A content was 97.0± 72.5 µg while that of iron was 1.5 ± 0.4 mg per 100g of food sample as fed. The contribution of indigenous complementary foods found was 32% for vitamin A and 15% iron of the recommended dietary allowance. Age of children was found to be significantly associated Vitamin A and Iron supply potential. Conclusion: The contribution of indigenous complementary foods to infant’s vitamin A and iron needs was low. Complementary foods in Uganda are more likely to be deficient in vitamin A and iron content. Nutrient dense dietary supplementation should be intervened in to make possible for Ugandan children attain full growth potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indigenous%20complementary%20food" title="indigenous complementary food">indigenous complementary food</a>, <a href="https://publications.waset.org/abstracts/search?q=infant" title=" infant"> infant</a>, <a href="https://publications.waset.org/abstracts/search?q=iron" title=" iron"> iron</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20A" title=" vitamin A "> vitamin A </a> </p> <a href="https://publications.waset.org/abstracts/33482/deficiencies-in-vitamin-a-and-iron-supply-potential-of-selected-indigenous-complementary-foods-of-infants-in-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33482.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">478</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">960</span> Energy Efficient Recycling of In-Plant Fines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Ahmed">H.

These alternative iron ore resources (fines) with unsatisfying physical and metallurgical properties are difficult to recycle. However, agglomerating these fines to be further used as a feed stock for existing iron and steel making processes is practiced successfully at several plants but for limited extent. In the present study, briquettes of integrated steelmaking industry waste materials (namely, BF-dust and sludge, BOF-dust and sludge) were used as feed stock to produce direct reduced iron (DRI). Physical and metallurgical properties of produced briquettes were investigated by means of TGA/DTA/QMS in combination with XRD. Swelling, softening and melting behavior were also studied using heating microscope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron%20and%20steel%20wastes" title="iron and steel wastes">iron and steel wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=self-reducing%20briquettes" title=" self-reducing briquettes"> self-reducing briquettes</a>, <a href="https://publications.waset.org/abstracts/search?q=thermogravimetry" title=" thermogravimetry"> thermogravimetry</a> </p> <a href="https://publications.waset.org/abstracts/9689/energy-efficient-recycling-of-in-plant-fines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9689.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">397</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">959</span> Iron Response Element-mRNA Binding to Iron Response Protein: Metal Ion Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mateen%20A.%20Khan">Mateen A.

Goss</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cellular iron homeostasis is accomplished by the coordinated regulated expression of iron uptake, storage, and export. Iron regulate the translation of ferritin and mitochondrial aconitase iron responsive element (IRE)-mRNA by interaction with an iron regulatory protein (IRPs). Iron increases protein biosynthesis encoded in iron responsive element. The noncoding structure IRE-mRNA, approximately 30-nt, folds into a stem loop to control synthesis of proteins in iron trafficking, cell cycling, and nervous system function. Fluorescence anisotropy measurements showed the presence of one binding site on IRP1 for ferritin and mitochondrial aconitase IRE-mRNA. Scatchard analysis revealed the binding affinity (Kₐ) and average binding sites (n) for ferritin and mitochondrial aconitase IRE-mRNA were 68.7 x 10⁶ M⁻¹ and 9.2 x 10⁶ M⁻¹, respectively. In order to understand the relative importance of equilibrium and stability, we further report the contribution of electrostatic interactions in the overall binding of two IRE-mRNA with IRP1. The fluorescence quenching of IRP1 protein was measured at different ionic strengths. The binding affinity of IRE-mRNA to IRP1 decreases with increasing ionic strength, but the number of binding sites was independent of ionic strength. Such results indicate a differential contribution of electrostatics to the interaction of IRE-mRNA with IRP1, possibly related to helix bending or stem interactions and an overall conformational change. Selective destabilization of ferritin and mitochondrial aconitase RNA/protein complexes as reported here explain in part the quantitative differences in signal response to iron in vivo and indicate possible new regulatory interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IRE-mRNA" title="IRE-mRNA">IRE-mRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=IRP1" title=" IRP1"> IRP1</a>, <a href="https://publications.waset.org/abstracts/search?q=binding" title=" binding"> binding</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20strength" title=" ionic strength"> ionic strength</a> </p> <a href="https://publications.waset.org/abstracts/101783/iron-response-element-mrna-binding-to-iron-response-protein-metal-ion-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101783.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">958</span> Acute Hepatotoxicity of Nano and Micro-Sized Iron Particles in Adult Albino Rats </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Hasabo">Ghada Hasabo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Saber%20Elbasiouny"> Mahmoud Saber Elbasiouny</a>, <a href="https://publications.waset.org/abstracts/search?q=Mervat%20Abdelsalam"> Mervat Abdelsalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Sherin%20Ghaleb"> Sherin Ghaleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Niveen%20Eldessouky"> Niveen Eldessouky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the near future, nanotechnology is envisaged for large scale use.
