The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals. Objective: To determine the prevalence and characteristics of consumption of nutraceuticals in undergraduate students. Methodology: Cross-sectional study. It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.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">576</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">116</span> Contemporary Mexican Shadow Politics: The War on Drugs and the Issue of Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lisdey%20Espinoza%20Pedraza">Lisdey Espinoza Pedraza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organised crime in Mexico evolves faster that our capacity to understand and explain it. Organised gangs have become successful entrepreneurs in many ways ad they have somehow mimicked the working ways of the authorities and in many cases, they have successfully infiltrated the governmental spheres. This business model is only possible under a clear scheme of rampant impunity. Impunity, however, is not exclusive to the PRI. Nor the PRI, PAN, or PRD can claim the monopoly of corruption, but what is worse is that none can claim full honesty in their acts either. The current security crisis in Mexico shows a crisis in the Mexican political party system. Corruption today is not only a problem of dishonesty and the correct use of public resources. It is the principal threat to Mexican democracy, governance, and national security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=security" title="security">security</a>, <a href="https://publications.waset.org/abstracts/search?q=war%20on%20drugs" title=" war on drugs"> war on drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20trafficking" title=" drug trafficking"> drug trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=Mexico" title=" Mexico"> Mexico</a>, <a href="https://publications.waset.org/abstracts/search?q=Latin%20America" title=" Latin America"> Latin America</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20States" title=" United States"> United States</a> </p> <a href="https://publications.waset.org/abstracts/20595/contemporary-mexican-shadow-politics-the-war-on-drugs-and-the-issue-of-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20595.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">417</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">115</span> Optimization of the Jatropha curcas Supply Chain as a Criteria for the Implementation of Future Collection Points in Rural Areas of Manabi-Ecuador </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20G.%20German">Boris G.

Narváez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The unique flora and fauna of The Galapagos Islands has leveraged a tourism-driven growth in the islands. Nonetheless, such development is energy-intensive and requires thousands of gallons of diesel each year for thermoelectric electricity generation. The needed transport of fossil fuels from the continent has generated oil spillages and affectations to the fragile ecosystem of the islands. The Zero Fossil Fuels initiative for The Galapagos proposed by the Ecuadorian government as an alternative to reduce the use of fossil fuels in the islands, considers the replacement of diesel in thermoelectric generators, by Jatropha curcas vegetable oil. However, the Jatropha oil supply cannot entirely cover yet the demand for electricity generation in Galapagos. Within this context, the present work aims to provide an optimization model that can be used as a selection criterion for approving new Jatropha Curcas collection points in rural areas of Manabi-Ecuador. For this purpose, existing Jatropha collection points in Manabi were grouped under three regions: north (7 collection points), center (4 collection points) and south (9 collection points). Field work was carried out in every region in order to characterize the collection points, to establish local Jatropha supply and to determine transportation costs. Data collection was complemented using GIS software and an objective function was defined in order to determine the profit associated to Jatropha oil production. The market price of both Jatropha oil and residual cake, were considered for the total revenue; whereas Jatropha price, transportation and oil extraction costs were considered for the total cost. The tonnes of Jatropha fruit and seed, transported from collection points to the extraction plant, were considered as variables. The maximum and minimum amount of the collected Jatropha from each region constrained the optimization problem. The supply chain was optimized using linear programming in order to maximize the profits. Finally, a sensitivity analysis was performed in order to find a profit-based criterion for the acceptance of future collection points in Manabi. The maximum profit reached a value of $ 4,616.93 per year, which represented a total Jatropha collection of 62.3 tonnes Jatropha per year. The northern region of Manabi had the biggest collection share (69%), followed by the southern region (17%). The criteria for accepting new Jatropha collection points in the rural areas of Manabi can be defined by the current maximum profit of the zone and by the variation in the profit when collection points are removed one at a time. The definition of new feasible collection points plays a key role in the supply chain associated to Jatropha oil production. Therefore, a mathematical model that assists decision makers in establishing new collection points while assuring profitability, contributes to guarantee a continued Jatropha oil supply for Galapagos and a sustained economic growth in the rural areas of Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collection%20points" title="collection points">collection points</a>, <a href="https://publications.waset.org/abstracts/search?q=Jatropha%20curcas" title=" Jatropha curcas"> Jatropha curcas</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20programming" title=" linear programming"> linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a> </p> <a href="https://publications.waset.org/abstracts/34611/optimization-of-the-jatropha-curcas-supply-chain-as-a-criteria-for-the-implementation-of-future-collection-points-in-rural-areas-of-manabi-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34611.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">433</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">114</span> Evaluation of Iron Oxide-Functionalized Multiwall Carbon Nanotube Self-Standing Electrode for Symmetric Supercapacitor Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20V.%20Bhaskara%20Rao">B.

This work focus on Fe₃O₄ nanoparticles synthesized by reverse co-precipitation and MWCNTs functionalized by –COOH acid functionalization. The results show that Optimized 25wt% Fe₃O₄@FMWCNT show high specific capacitance 100 mF/cm² at one mA/cm² whereas 15wt% Fe₃O₄@FMWCNT showed high stability (80% retention capacity) over 5000 cycles. The electrolyte used in the coin cell is LiPF6 and the thickness of the electrode is 30 microns. The optimized Fe₃O₄@FMWCNT bucky papers coin cell electrochemical studies suggest that 25wt% Fe₃O₄@FMWCNT could be a good candidate for high-capacity supercapacitor devices.

Glucotropaeolonin is one of its main components, which when hydrolyzed, forms benzyl isothiocyanate (BIT) that promotes cellular apoptosis (programmed cell death in cancer cells). Therefore, the present research aims to evaluate the effect of the pressure and temperature of BIT extraction by supercritical CO<sub>2</sub> from <em>Tropaeolum majus</em> L. The extraction was carried out in a supercritical fluid extractor equipment Speed SFE BASIC Brand: Poly science, the leaves of <em>Tropaeolum majus</em> L. were ground for one hour and lyophilized until obtaining a humidity of 6%. The extraction with supercritical CO<sub>2</sub> was carried out with pressures of 200 bar and 300 bar, temperatures of 50°C, 60°C and 70°C, obtained by the conjugation of these six treatments. BIT was identified by thin layer chromatography using 98% BIT as the standard, and as the mobile phase hexane: dichloromethane (4:2). Subsequently, BIT quantification was performed by high performance liquid chromatography (HPLC). The highest yield of oleoresin by supercritical CO<sub>2</sub> extraction was obtained pressure 300 bar and temperature at 60°C; and the higher content of BIT at pressure 200 bar and 70°C for 30 minutes to obtain 113.615 ± 0.03 mg BIT/100 g dry matter was obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title="solvent extraction">solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=Tropaeolum%20majus%20L." title=" Tropaeolum majus L."> Tropaeolum majus L.</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20fluids" title=" supercritical fluids"> supercritical fluids</a>, <a href="https://publications.waset.org/abstracts/search?q=benzyl%20isothiocyanate" title=" benzyl isothiocyanate"> benzyl isothiocyanate</a> </p> <a href="https://publications.waset.org/abstracts/76739/effects-of-pressure-and-temperature-on-the-extraction-of-benzyl-isothiocyanate-by-supercritical-fluids-from-tropaeolum-majus-l-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76739.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">111</span> Managing of Work Risk in Small and Medium-Size Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Janusz%20K.%20Grabara">Janusz K.

This paper adds to our knowledge of this growing problem among collegiate athletes. National athletic associations and educational institutions are more knowledgeable of the mental health crisis facing hundreds of thousands of athletes each year, and some have implemented resources to improve mental health. However, college athletes continue to experience depressive symptoms at increasing rates. In this paper, depression rates for the vast numbers of collegiate athletes were found to be significantly greater than the general adult population. This paper used the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method to examine the literature’s findings on depression rates among collegiate athletes. Particularly, this study answers questions related to risk factors of college athletes’ depressive symptoms. Risk factors unique to this population are also discussed. Prevalence rates by sport participant gender and sport are provided. Implementation measures in current practice at educational institutions in the U.S. are discussed to help alleviate depression rates among college athletes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=college%20athletes" title="college athletes">college athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a> </p> <a href="https://publications.waset.org/abstracts/182025/depressive-symptoms-of-us-collegiate-athletes-risk-factors-and-implementations-for-mental-health-well-being-for-athletes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182025.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">65</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">109</span> A Fuzzy-Logic Approach to Rule-Based Systems for Leadership Style Selection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kim%20Michelle%20Siegling">Kim Michelle Siegling</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Spengler"> Thomas Spengler</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Herzog"> Sebastian Herzog</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In personnel economics, the choice of a leadership style is about the question of how a supervisor should lead his or her employees in such a way that operational goals are achieved. In this paper, it is assumed that such leadership decisions are made according to the situation. Thus, the optimal or at least a permissible leadership style has to be selected from a set of several possible leadership styles. For this choice, a wide range of models has been developed in the scientific literature, from which the so-called normative decision model will be picked out and focused on. While the original model is based on univocal rules, this paper develops a fuzzy rule system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leadership" title="leadership">leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership%20styles" title=" leadership styles"> leadership styles</a>, <a href="https://publications.waset.org/abstracts/search?q=rule%20based%20systems" title=" rule based systems"> rule based systems</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a> </p> <a href="https://publications.waset.org/abstracts/186818/a-fuzzy-logic-approach-to-rule-based-systems-for-leadership-style-selection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186818.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">41</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">108</span> Marketing Practices of the Urban and Recycled Wood Industry in the United States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Smith">Robert Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Espinoza"> Omar Espinoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Pitta"> Anna Pitta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the United States, trees felled in urban areas and wood generated through construction and demolition are primarily disposed of as low-value resources, such as biomass for energy, landscaping mulch, composting, or landfilled. An emerging industry makes use of these underutilized resources to produce high value-added products, with associated benefits for the environment, the local economy, and consumers. For the circular economy to be successful, markets must be created for sustainable, reusable natural materials. Research was carried out to increase the understanding of the marketing practices of urban and reclaimed wood industries. This paper presents the results of a nationwide survey of these companies. The results indicate that a majority of companies in this industry are small firms, operating for less than 10 years, which produce mostly to order and sell their products at comparatively higher prices than competing products made from virgin natural resources. Promotional messages included quality, aesthetics, and customization, conveyed through company webpages, word of mouth, and social media. Distribution channels used include direct sales, online sales, and retail sales. Partnerships are critical for effective raw material procurement. Respondents indicated optimistic growth expectations, despite barriers associated with urban and reclaimed wood materials and production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20and%20reclaimed%20wood" title="urban and reclaimed wood">urban and reclaimed wood</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20economy" title=" circular economy"> circular economy</a>, <a href="https://publications.waset.org/abstracts/search?q=marketing" title=" marketing"> marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20products" title=" wood products"> wood products</a> </p> <a href="https://publications.waset.org/abstracts/123108/marketing-practices-of-the-urban-and-recycled-wood-industry-in-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123108.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">125</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">107</span> Electricity Market Categorization for Smart Grid Market Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rebeca%20Ramirez%20Acosta">Rebeca Ramirez Acosta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Lenhoff"> Sebastian Lenhoff</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Decision makers worldwide need to determine if the implementation of a new market mechanism will contribute to the sustainability and resilience of the power system. Due to smart grid technologies, new products in the distribution and transmission system can be traded; however, the impact of changing a market rule will differ between several regions. To test systematically those impacts, a market categorization has been compiled and organized in a smart grid market testing toolbox. This toolbox maps all actual energy products and sets the basis for running a co-simulation test with the new rule to be implemented.

In this paper, we analyze the challenges and opportunities of implementing cloud computing in healthcare. We also analyze data of over 5000 US hospitals that use Telemedicine applications. This analysis helps to understand the importance of smart phones over the desktop systems in different departments of the healthcare institutions. The wide usage of smartphones and cloud computing allows ubiquitous and affordable access to the health data by authorized persons, including patients and doctors. Cloud computing will prove to be beneficial to a majority of the departments in healthcare.

Many countries have embarked upon a process of democratisation for the first time while many others have moved to restore their democratic roots. Mexico is one of these countries, and although the Mexican state is not democratic neither dictatorial in the strict sense the Anglo-Saxon and European tradition has defined these concepts, it is possible to find elements that combine both concepts. History helps us understand and study the past, interpret the present and predict the future. In the case of the Mexican political system, history has had a very specific effect in each of the areas that comprise the making of what it is now the contemporary Mexican system. Each of the different historical periods has left a legacy that has marked the way the political system has evolved. The historical periods that Mexico has undergone since its emergence as an independent state, have permeated until modern days and some of these legacies are the ones which will help us understand and interpret many of the structures of the current Mexican political system. The most notorious characteristic of contemporary Latin America is its dependency, underdevelopment and economic disparity once this region if compared with Europe and North America. There is a widespread persistence of economic dependence and social problems despite the creation of independent countries. The role of the state is to supervise the development of relations among actors. The political phenomenon is full of a constant process of transitions and the particular case of the formation of the Mexican state evidences this. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mexico" title="Mexico">Mexico</a>, <a href="https://publications.waset.org/abstracts/search?q=democratisation%20process" title=" democratisation process"> democratisation process</a>, <a href="https://publications.waset.org/abstracts/search?q=PRI" title=" PRI"> PRI</a>, <a href="https://publications.waset.org/abstracts/search?q=authoritarian%20regimes" title=" authoritarian regimes"> authoritarian regimes</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20transitions" title=" political transitions"> political transitions</a>, <a href="https://publications.waset.org/abstracts/search?q=Latin%20America" title=" Latin America"> Latin America</a> </p> <a href="https://publications.waset.org/abstracts/20594/the-structural-pillars-in-contemporary-mexico-legacies-of-the-past-and-lessons-for-the-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20594.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">292</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">101</span> CMOS Solid-State Nanopore DNA System-Level Sequencing Techniques Enhancement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Islam">Syed Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Yiyun%20Huang"> Yiyun Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Magierowski"> Sebastian Magierowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Ghafar-Zadeh"> Ebrahim Ghafar-Zadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents system level CMOS solid-state nanopore techniques enhancement for speedup next generation molecular recording and high throughput channels.

The purpose of the method is to improve the computational efficiency, while maintaining a high solution accuracy, by projection the governing equations onto a small set of carefully selected basis vectors. The present work considers basis projection in kinematic nonlinear systems with a focus on two widely used basis vectors; the system mode shapes and their modal derivatives. Particularly the latter basis vectors are given special attention since only approximate modal derivatives have been used until now. In the present work the complete modal derivatives, derived from perturbation methods, are presented and compared to the previously applied approximate modal derivatives. The correctness of the complete modal derivatives is illustrated by use of an example of a harmonically loaded kinematic nonlinear structure modeled by beam elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basis%20projection" title="basis projection">basis projection</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematic%20nonlinearities" title=" kinematic nonlinearities"> kinematic nonlinearities</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20derivatives" title=" modal derivatives"> modal derivatives</a> </p> <a href="https://publications.waset.org/abstracts/92260/the-complete-modal-derivatives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92260.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">99</span> Optimal Concentration of Fluorescent Nanodiamonds in Aqueous Media for Bioimaging and Thermometry Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Pedroza-Montero">Francisco Pedroza-Montero</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Na%C3%ADn%20Pedroza-Montero"> Jesús Naín Pedroza-Montero</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Soto-Puebla"> Diego Soto-Puebla</a>, <a href="https://publications.waset.org/abstracts/search?q=Osiris%20Alvarez-Bajo"> Osiris Alvarez-Bajo</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Castaneda"> Beatriz Castaneda</a>, <a href="https://publications.waset.org/abstracts/search?q=Sof%C3%ADa%20Navarro-Espinoza"> Sofía Navarro-Espinoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Mart%C3%ADn%20Pedroza-Montero"> Martín Pedroza-Montero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanodiamonds have been widely studied for their physical properties, including chemical inertness, biocompatibility, optical transparency from the ultraviolet to the infrared region, high thermal conductivity, and mechanical strength. In this work, we studied how the fluorescence spectrum of nanodiamonds quenches concerning the concentration in aqueous solutions systematically ranging from 0.1 to 10 mg/mL. Our results demonstrated a non-linear fluorescence quenching as the concentration increases for both of the NV zero-phonon lines; the 5 mg/mL concentration shows the maximum fluorescence emission. Furthermore, this behaviour is theoretically explained as an electronic recombination process that modulates the intensity in the NV centres. Finally, to gain more insight, the FRET methodology is used to determine the fluorescence efficiency in terms of the fluorophores' separation distance. Thus, the concentration level is simulated as follows, a small distance between nanodiamonds would be considered a highly concentrated system, whereas a large distance would mean a low concentrated one. Although the 5 mg/mL concentration shows the maximum intensity, our main interest is focused on the concentration of 0.5 mg/mL, which our studies demonstrate the optimal human cell viability (99%). In this respect, this concentration has the feature of being as biocompatible as water giving the possibility to internalize it in cells without harming the living media. To this end, not only can we track nanodiamonds on the surface or inside the cell with excellent precision due to their fluorescent intensity, but also, we can perform thermometry tests transforming a fluorescence contrast image into a temperature contrast image. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanodiamonds" title="nanodiamonds">nanodiamonds</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence%20spectroscopy" title=" fluorescence spectroscopy"> fluorescence spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=bioimaging" title=" bioimaging"> bioimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=thermometry" title=" thermometry"> thermometry</a> </p> <a href="https://publications.waset.org/abstracts/142223/optimal-concentration-of-fluorescent-nanodiamonds-in-aqueous-media-for-bioimaging-and-thermometry-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142223.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">404</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">98</span> Solid Particle Erosion of Heat Treated TNB-V4 at Ambient and Elevated Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naveed">Muhammad Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Stechow"> Richard Stechow</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Bolz"> Sebastian Bolz</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Hobusch"> Katharina Hobusch</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabine%20Wei%C3%9F"> Sabine Weiß</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid particle erosion has been identified as a critical wear phenomenon which takes place during operation of aeroengines in dusty environment. The present work discusses the erosion behavior of Ti-44.5Al-6.25Nb-0.8Mo-0.1B alloy (TNB-V4) which finds its application in low pressure gas turbines and can be used for high pressure compressors too. Prior to the erosion tests, the alloy was heat treated to improve the mechanical properties. Afterwards, specimens were eroded at impact angles of 30° and 90° at room and high temperatures (100 °C-400 °C). Volume loss and erosion behavior are studied through gravimetric analysis, whereas erosion mechanisms are characterized through scanning electron microscopy. The results indicate a clear difference in the erosion mechanism for different impact angles. The influence of the test temperature on the erosion behavior of the alloy is also discussed in the present contribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20particle%20erosion" title="solid particle erosion">solid particle erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20TiAl" title=" gamma TiAl"> gamma TiAl</a>, <a href="https://publications.waset.org/abstracts/search?q=TNB-V4" title=" TNB-V4"> TNB-V4</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20temperature%20erosion" title=" high temperature erosion"> high temperature erosion</a> </p> <a href="https://publications.waset.org/abstracts/49747/solid-particle-erosion-of-heat-treated-tnb-v4-at-ambient-and-elevated-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49747.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">353</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">97</span> Governance of Inter-Organizational Research Cooperation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Woelk"> Sebastian Woelk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Companies face increasing challenges in research due to higher costs and risks. The intensifying technology complexity and interdisciplinarity require unique know-how. Therefore, companies need to decide whether research shall be conducted internally or externally with partners. On the other hand, research institutes meet increasing efforts to achieve good financing and to maintain high research reputation. Therefore, relevant research topics need to be identified and specialization of competency is necessary. However, additional competences for solving interdisciplinary research projects are also often required. Secured financing can be achieved by bonding industry partners as well as public fundings. The realization of faster and better research drives companies and research institutes to cooperate in organized research networks, which are managed by an administrative organization. For an effective and efficient cooperation, necessary processes, roles, tools and a set of rules need to be determined.

The CdS thin films were annealed in air, argon, hydrogen and nitrogen for 1 h at various temperatures (300, 350, 400, 450 and 500 °C). The changes in optical and electrical properties of annealed treated CdS thin films were analyzed. The results showed that, the band-gap and resistivity depend on the post-deposition annealing atmosphere and temperatures. Thus, it was found that these properties of the films, were found to be affected by various processes with opposite effects, some beneficial and others unfavorable. The energy gap and resistivity for different annealing atmospheres was seen to oscillate by thermal annealing. Recrystallization, oxidation, surface passivation, sublimation and materials evaporation were found the main factors of the heat-treatment process responsible for this oscillating behavior. Annealing over 400 °C was seen to degrade the optical and electrical properties of the film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cds" title="cds">cds</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing" title=" annealing"> annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=optical" title=" optical"> optical</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/31251/characterization-of-chemically-deposited-cds-thin-films-annealed-in-different-atmospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31251.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">510</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">94</span> Attitude to Cultural Diversity and Inclusive Pedagogical Practices in the Classroom: A Correlational Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20M.%20Espinoza">Laura M.

This phenomenon has reached the schools of Chile, where immigrant children and adolescents are educated in a context of cultural diversity. However, education professionals face this recent phenomenon without prior preparation to carry out their pedagogical practices in the classroom. On the other hand, research on how to understand and guide the processes of cultural diversity especially within the school is even scarce and recent in Latin America and specifically in Chile. The general purpose of the study is to analyze the relationships between teaching efforts towards multiculturalism and inclusive pedagogical practices in the schools of the city of La Serena and Coquimbo, in Chile. The study refers to a quantitative approach, with a correlational design. The selection of the participants was not intentional probabilistic. It comprises 88 teachers of preschool, primary, secondary and special education, who work in two schools with similar characteristics. For the collection of information on the independent variable, the attitude scale towards Immigration and the attitude scale towards Multiculturalism in the school are applied. To obtain information on the independent variable, the guide for the evaluation of inclusive practices in the classroom is applied. Both instruments have statistical validation. A Spearman correlation analysis was made to achieve the objective of the study. Among the main findings, we will find the relationships between the positive perceptions of multiculturalism at school and inclusive practices such as the physical conditions of the classroom, planning, methodology, use of time and evaluation. These findings are relevant to the teaching and learning processes of students in Chilean classrooms and contribute to literature for the understanding of educational processes in contexts of cultural diversity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20diversity" title="cultural diversity">cultural diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=immigration" title=" immigration"> immigration</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusive%20pedagogical%20practices" title=" inclusive pedagogical practices"> inclusive pedagogical practices</a>, <a href="https://publications.waset.org/abstracts/search?q=multiculturalism" title=" multiculturalism"> multiculturalism</a> </p> <a href="https://publications.waset.org/abstracts/106761/attitude-to-cultural-diversity-and-inclusive-pedagogical-practices-in-the-classroom-a-correlational-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106761.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">121</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">93</span> Effect of Injection Strategy on the Performance and Emission of E85 in a Heavy-Duty Engine under Partially Premixed Combustion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Aziz">Amir Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Tuner"> Martin Tuner</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Verhelst"> Sebastian Verhelst</a>, <a href="https://publications.waset.org/abstracts/search?q=Oivind%20Andersson"> Oivind Andersson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Partially Premixed Combustion (PPC) is a combustion concept which aims to simultaneously achieve high efficiency and low engine-out emissions. Extending the ignition delay to promote the premixing, has been recognized as one of the key factor to achieve PPC. Fuels with high octane number have been proven to be a good candidates to extend the ignition delay. In this work, E85 (85% ethanol) has been used as a PPC fuel. The aim of this work was to investigate a suitable injection strategy for PPC combustion fueled with E85 in a single-cylinder heavy-duty engine. Single and double injection strategy were applied with different injection timing and the ratio between different injection pulses was varied. The performance and emission were investigated at low load. The results show that the double injection strategy should be preferred for PPC fueled with E85 due to low emissions and high efficiency, while keeping the pressure raise rate at very low levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E85" title="E85">E85</a>, <a href="https://publications.waset.org/abstracts/search?q=partially%20premixed%20combustion" title=" partially premixed combustion"> partially premixed combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20strategy" title=" injection strategy"> injection strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20and%20emission" title=" performance and emission"> performance and emission</a> </p> <a href="https://publications.waset.org/abstracts/85102/effect-of-injection-strategy-on-the-performance-and-emission-of-e85-in-a-heavy-duty-engine-under-partially-premixed-combustion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85102.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">177</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">92</span> An Evaluation Model for Enhancing Flexibility in Production Systems through Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angela%20Luft">Angela Luft</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Bremen"> Sebastian Bremen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolae%20Balc"> Nicolae Balc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Additive manufacturing processes have entered large parts of the industry and their range of application have progressed and grown significantly in the course of time. A major advantage of additive manufacturing is the innate flexibility of the machines. This corelates with the ongoing demand of creating highly flexible production environments. However, the potential of additive manufacturing technologies to enhance the flexibility of production systems has not yet been truly considered and quantified in a systematic way. In order to determine the potential of additive manufacturing technologies with regards to the strategic flexibility design in production systems, an integrated evaluation model has been developed, that allows for the simultaneous consideration of both conventional as well as additive production resources. With the described model, an operational scope of action can be identified and quantified in terms of mix and volume flexibility, process complexity, and machine capacity that goes beyond the current cost-oriented approaches and offers a much broader and more holistic view on the potential of additive manufacturing.

A physical model that can quantitatively explain the evolution of out of plane A1g and in-plane E1g Raman modes is used. The non-linear variation of peak positions of the Raman modes with temperature is explained by anharmonic three-phonon and four-phonon processes along with thermal expansion of the lattice. We also observe prominent effect of electron-phonon coupling from the variation of FWHM of the peaks with temperature, indicating the metallicity of the samples. Raman mode E1 1g corresponding to an in plane vibration disappears on decreasing the thickness from bulk to nanoflake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title="raman spectroscopy">raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20dirac%20semimetal" title=" type 2 dirac semimetal"> type 2 dirac semimetal</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20telluride" title=" nickel telluride"> nickel telluride</a>, <a href="https://publications.waset.org/abstracts/search?q=phonon-phonon%20coupling" title=" phonon-phonon coupling"> phonon-phonon coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20phonon%20coupling" title=" electron phonon coupling"> electron phonon coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20metal%20dichalcogonide" title=" transition metal dichalcogonide"> transition metal dichalcogonide</a> </p> <a href="https://publications.waset.org/abstracts/148958/temperature-dependent-structural-characterization-of-type-ii-dirac-semi-metal-nite2-from-bulk-to-exfoliated-thin-flakes-using-raman-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148958.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">114</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">90</span> Method for Evaluating the Monetary Value of a Customized Version of the Digital Twin for the Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Oettl">Fabio Oettl</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Hoerbrand"> Sebastian Hoerbrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Wittmeir"> Tobias Wittmeir</a>, <a href="https://publications.waset.org/abstracts/search?q=Johannes%20Schilp"> Johannes Schilp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By combining the additive manufacturing (AM)- process with digital concepts, like the digital twin (DT) or the downsized and basing concept of the digital part file (DPF), the competitiveness of additive manufacturing is enhanced and new use cases like decentral production are enabled. But in literature, one can´t find any quantitative approach for valuing the usage of a DT or DPF in AM. Out of this fact, such an approach will be developed within this paper in order to further promote or dissuade the usage of these concepts. The focus is set on the production as an early lifecycle phase, which means that the AM-production process gets analyzed regarding the potential advantages of using DPF in AM. These advantages are transferred to a monetary value with this approach. By calculating the costs of the DPF, an overall monetary value is a result. Thereon a tool, based on a simulation environment is constructed, where the algorithms are transformed into a program. The results of applying this tool show that an overall value of 20,81 € for the DPF can be realized for one special use case. For the future application of the DPF there is the recommendation to integrate especially sustainable information because out of this, a higher value of the DPF can be expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20concept%20costs" title=" digital concept costs"> digital concept costs</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20part%20file" title=" digital part file"> digital part file</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20twin" title=" digital twin"> digital twin</a>, <a href="https://publications.waset.org/abstracts/search?q=monetary%20value%20estimation" title=" monetary value estimation"> monetary value estimation</a> </p> <a href="https://publications.waset.org/abstracts/133143/method-for-evaluating-the-monetary-value-of-a-customized-version-of-the-digital-twin-for-the-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133143.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">200</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">89</span> Student Performance and Confidence Analysis on Education Virtual Environments through Different Assessment Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20Manrique">Rubén Manrique</a>, <a href="https://publications.waset.org/abstracts/search?q=Delio%20Balc%C3%A1zar"> Delio Balcázar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Parrado"> José Parrado</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebasti%C3%A1n%20Rodr%C3%ADguez"> Sebastián Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hand in hand with the evolution of technology, education systems have moved to virtual environments to provide increased coverage and facilitate the access to education. However, measuring student performance in virtual environments presents significant challenges to ensure students are acquiring the expected skills. In this study, the confidence and performance of engineering students in virtual environments is analyzed through different evaluation strategies. The effect of the assessment strategy in student confidence is identified using educational data mining techniques. Four assessment strategies were used. First, a conventional multiple choice test; second, a multiple choice test with feedback; third, a multiple choice test with a second chance; and fourth; a multiple choice test with feedback and second chance. Our results show that applying testing with online feedback strategies can influence positively student confidence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment%20strategies" title="assessment strategies">assessment strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20data%20mining" title=" educational data mining"> educational data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20performance" title=" student performance"> student performance</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20confidence" title=" student confidence"> student confidence</a> </p> <a href="https://publications.waset.org/abstracts/46676/student-performance-and-confidence-analysis-on-education-virtual-environments-through-different-assessment-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46676.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">88</span> Diaper Dermatitis and Pancytopenia as the Primary Manifestation in an Infant with Vitamin B12 Deficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekaterina%20S%C3%A1nchez%20Romero">Ekaterina Sánchez Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Emily%20Gabriela%20Aguirre%20Herrera"> Emily Gabriela Aguirre Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Luz%20%20Espinoza%20Esquerra"> Sandra Luz Espinoza Esquerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Garc%C3%ADa%20Campos"> Jorge García Campos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Female, 7 months old, daughter of a mother with anemia during pregnancy, with no history of atopy in the family, since birth she presents with recurrent dermatological and gastrointestinal infections, chronically treated for recurrent diaper dermatitis. At 6 months of age, she begins with generalized pallor, hyperpigmentation in hands and feet, smooth tongue, psychomotor retardation with lack of head support, sedation, and hypoactivity. She was referred to our hospital for a fever of 38°C, severe diaper rash, and pancytopenia with HB 9.3, platelets 38000, neutrophils 0.39 MCV: 86.80 high for her age. The approach was initiated to rule out myeloproliferative syndrome, with negative immunohistochemical results of bone marrow aspirate; during her stay, she presented neurological regression, lack of sucking, and focal seizures. CT scan showed cortical atrophy. The patient was diagnosed with primary immunodeficiency due to history; gamma globulin was administered without improvement with normal results of immunoglobulins and metabolic screening. When dermatological and neurological diagnoses were ruled out as the primary cause, a nutritional factor was evaluated, and a therapeutic trial was started with the administration of vitamin B12 and zinc, presenting clinical neurological improvement and resolution of pancytopenia in 2 months. It was decided to continue outpatient management. Discussion: We present a patient with neurological, dermatological involvement, and pancytopenia, so the most common differential diagnoses in this population were ruled out. Vitamin B12 deficiency is an uncommon entity. Due to maternal and clinical history, a therapeutic trial was started resulting in an improvement. Conclusion: VitaminB12 deficiency should be considered one of the differential diagnoses in the approach to pancytopenia with megaloblastic anemia associated with dermatologic and neurologic manifestations. Early treatment can reduce irreversible damage in these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vitamin%20B12%20deficiency"
