The Diagnostic and Statistical Manual of Mental Disorders-5 supports early onset of PD and views the pattern of behaviors as enduring and stable. The premise of this study is that PD may not always begin early in life, that behaviors may change over the lifespan, and that current treatment modalities may be beneficial in seniors. Self-injurious behaviors (SIB) exhibited earlier in life may, in older adults, be manifested in less overt high-risk behaviors but by refusal to take medication and get necessary medical treatment. Dialectical Behavioral Therapy is a well-known treatment modality for teaching emotional regulation and distress tolerance and thus reducing self-injurious behaviors yet very little has been studied about SIB and treatment in older adults. The population for this study was older adults, with a history of SIB, a PD, and depression and/or anxiety. Participants learned an adapted version of Dialectical Behavioral Therapy (DBT) as developed by DBT trained therapists. The results provided clinical potentials for the efficacy of DBT to reduce SIB, decrease depression and anxiety in the older adult population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety" title="anxiety">anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=dialectical%20behavioral%20therapy" title=" dialectical behavioral therapy"> dialectical behavioral therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=personality%20disorders" title=" personality disorders"> personality disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=self-harm%20behavior" title=" self-harm behavior"> self-harm behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20in%20older%20adults" title=" treatment in older adults"> treatment in older adults</a> </p> <a href="https://publications.waset.org/abstracts/56219/a-dialectical-behavioral-therapy-adaptation-in-reducing-depression-anxiety-and-self-harm-in-older-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56219.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">302</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">155</span> Non-Dominated Sorting Genetic Algorithm (NSGA-II) for the Redistricting Problem in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonin%20Ponsich">Antonin Ponsich</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Alfredo%20Rincon%20Garcia"> Eric Alfredo Rincon Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Anselmo%20Mora%20Gutierrez"> Roman Anselmo Mora Gutierrez</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Angel%20Gutierrez%20Andrade"> Miguel Angel Gutierrez Andrade</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Gerardo%20De%20Los%20Cobos%20Silva"> Sergio Gerardo De Los Cobos Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Lara%20Velzquez"> Pedro Lara Velzquez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electoral zone design problem consists in redrawing the boundaries of legislative districts for electoral purposes in such a way that federal or state requirements are fulfilled. In Mexico, this process has been historically carried out by the National Electoral Institute (INE), by optimizing an integer nonlinear programming model, in which population equality and compactness of the designed districts are considered as two conflicting objective functions, while contiguity is included as a hard constraint. The solution technique used by the INE is a Simulated Annealing (SA) based algorithm, which handles the multi-objective nature of the problem through an aggregation function. The present work represents the first intent to apply a classical Multi-Objective Evolutionary Algorithm (MOEA), the second version of the Non-dominated Sorting Genetic Algorithm (NSGA-II), to this hard combinatorial problem. First results show that, when compared with the SA algorithm, the NSGA-II obtains promising results. The MOEA manages to produce well-distributed solutions over a wide-spread front, even though some convergence troubles for some instances constitute an issue, which should be corrected in future adaptations of MOEAs to the redistricting problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-objective%20optimization" title="multi-objective optimization">multi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=NSGA-II" title=" NSGA-II"> NSGA-II</a>, <a href="https://publications.waset.org/abstracts/search?q=redistricting" title=" redistricting"> redistricting</a>, <a href="https://publications.waset.org/abstracts/search?q=zone%20design%20problem" title=" zone design problem"> zone design problem</a> </p> <a href="https://publications.waset.org/abstracts/69281/non-dominated-sorting-genetic-algorithm-nsga-ii-for-the-redistricting-problem-in-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69281.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">154</span> Resistance of Haemonchus spp. to Albendazole, Fenbendazole and Levamisole in 4 Goat Farms of Antioquia, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20D.%20Zapata-Torres">Jose D.

In some regions of world, the extremely high prevalence of multi-drug resistance in nematodes of sheep and goats threatens the viability of small-ruminant industries. In the region of Antioquia, Colombia, no reports of nematode resistance have been documented due to a lack of veterinary diagnostic laboratories. The objective of this study was to evaluate the efficacy of albendazole, fenbendazole, and levamisole to control gastrointestinal nematodes in goat farms of Antioquia by doing fecal egg count reduction tests. A total of 139 crossbreed goats from four separate farms were sampled for feces prior to, and 14 days following anthelmintc treatments. Individual fecal egg counts were performed using the modified three chamber McMaster technique. The anthelmintics administered at day 0 were albendazole (farm 1, n=63), fenbendazole (farm 2, n=20), and levamisole (farm 3 and 4, n= 37, and 19). Larval cultures were used to identify the genus of nematodes using Baermann`s technique and the morphological keys for identification of L3 in small ruminants. There was no difference in fecal egg counts between 0 and 14, with means (±SD) of 1681,5 ± 2121,5 and 1715,12 ± 1895,4 epg (eggs per gram), respectively. The egg count reductions for each anthelmintic and farm were 25,86% for albendazole (farm 1), 0% for fenbendazole (farm 2), 0% (farm 3), and 5,5% (farm 4) for levamisole. The genus of nematodes identified was predominantly Haemonchus spp., with 70,27% and 82,81% for samples from day 0 and 14, respectively. These results provide evidence of a total state of resistance to 3 common anthelmintics. Further research is needed to design integrate management programs to control nematodes in small ruminants in Colombia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthelmintics" title="anthelmintics">anthelmintics</a>, <a href="https://publications.waset.org/abstracts/search?q=goat" title=" goat"> goat</a>, <a href="https://publications.waset.org/abstracts/search?q=haemonchus" title=" haemonchus"> haemonchus</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a> </p> <a href="https://publications.waset.org/abstracts/16404/resistance-of-haemonchus-spp-to-albendazole-fenbendazole-and-levamisole-in-4-goat-farms-of-antioquia-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16404.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">528</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">153</span> Comparative Analysis of the Performance Between Public and Private Companies: Explanatory Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atziri%20Moreno%20Vite">Atziri Moreno Vite</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Silva%20Guti%C3%A9rrez"> David Silva Gutiérrez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil companies have become the key player in the world energy scenario thanks to their strong control of the level of hydrocarbon reserves and production.

These fish rearing systems are approximately two thirds of aquatic production in this area which has made a significant contribution to the regional economy in recent years. In this type of rearing system, a crucial aspect is the correct quantification and control of the fish abundance in the ponds because the fish farmer knows how many fishes he puts in the ponds but doesn’t know how many fishes will harvest at the end of the rear period. This is a consequence of the mortality induced by different causes as pathogen agents as parasites, viruses and bacteria and other factors as predation of fish-eating birds and poaching. Track the fish abundance in these installations is very difficult because usually the ponds take up a large area of land and the management of the water flow is not automatized. Therefore, there is a very high degree of uncertainty on the abundance fishes which strongly hinders the management and planning of the sales. A novel and non-invasive procedure to count fishes in the ponds is by the means of imaging sonars, particularly fixed systems and/or linked to aquatic vehicles as Remotely Operated Vehicles (ROVs). In this work, a method based on census stations procedures is proposed to evaluate the fish abundance estimation accuracy using images obtained of multibeam sonars. The results indicate that it is possible to obtain a realistic approach about the number of fishes, sizes and therefore the biomass contained in the ponds.

Fortified food must meet the demand of the population, taking into account their habits and risks that these foods may cause. Wheat and its by-products, such as semolina, has been strongly indicated to be used as a food vehicle since it is widely consumed and used in the production of other foods. These products have been strategically used to add some nutrients, such as fibers. Methods of analysis and quantification of these kinds of components are destructive and require lengthy sample preparation and analysis. Therefore, the industry has searched for faster and less invasive methods, such as Near-Infrared Spectroscopy (NIR). NIR is a rapid and cost-effective method, however, it is based on indirect measurements, yielding high amount of data. Therefore, NIR spectroscopy requires calibration with mathematical and statistical tools (Chemometrics) to extract analytical information from the corresponding spectra, as Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). PCA is well suited for NIR, once it can handle many spectra at a time and be used for non-supervised classification. Advantages of the PCA, which is also a data reduction technique, is that it reduces the data spectra to a smaller number of latent variables for further interpretation. On the other hand, LDA is a supervised method that searches the Canonical Variables (CV) with the maximum separation among different categories. In LDA, the first CV is the direction of maximum ratio between inter and intra-class variances. The present work used a portable infrared spectrometer (NIR) for identification and classification of pure and fiber-fortified semolina samples. The fiber was added to semolina in two different concentrations, and after the spectra acquisition, the data was used for PCA and LDA to identify and discriminate the samples. The results showed that NIR spectroscopy associate to PCA was very effective in identifying pure and fiber-fortified semolina. Additionally, the classification range of the samples using LDA was between 78.3% and 95% for calibration and 75% and 95% for cross-validation. Thus, after the multivariate analysis such as PCA and LDA, it was possible to verify that NIR associated to chemometric methods is able to identify and classify the different samples in a fast and non-destructive way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chemometrics" title="Chemometrics">Chemometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber" title=" fiber"> fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20discriminant%20analysis" title=" linear discriminant analysis"> linear discriminant analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=near-infrared%20spectroscopy" title=" near-infrared spectroscopy"> near-infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=semolina" title=" semolina"> semolina</a> </p> <a href="https://publications.waset.org/abstracts/81774/identification-and-classification-of-fiber-fortified-semolina-by-near-infrared-spectroscopy-nir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81774.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">212</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">149</span> Design of a Chaotic Trajectory Generator Algorithm for Mobile Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20J.%20Cetina-Denis">J.

The design of the handle is based on ergonomic principles and tries to avoid awkward postures for surgeons. The handle combines the so-called power-grip and accurate-grip in order to provide strength and accuracy in the performance of surgery. The handle is tested using both objective and subjective approaches. The objective approach uses motion capture techniques to obtain the angles of forearm, arm, wrist and hand. The muscular effort is obtained with electromyography electrodes. On the other hand, a subjective survey has been carried out using questionnaires. Results confirm that the handle is preferred by the majority of the surgeons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laparoscopic%20surgery" title="laparoscopic surgery">laparoscopic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title=" ergonomics"> ergonomics</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20design" title=" mechanical design"> mechanical design</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a> </p> <a href="https://publications.waset.org/abstracts/41496/an-ergonomic-handle-design-for-instruments-in-laparoscopic-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41496.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">502</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">145</span> Genomic Evidence for Ancient Human Migrations Along South America's East Coast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andre%20Luiz%20Campelo%20dos%20Santos">Andre Luiz Campelo dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Owings"> Amanda Owings</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Socrates%20Lavalle%20Sullasi"> Henry Socrates Lavalle Sullasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Omer%20Gokcumen"> Omer Gokcumen</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20DeGiorgio"> Michael DeGiorgio</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Lindo"> John Lindo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An increasing body of archaeological and genomic evidence have indicated a complex settlement process of the Americas.

The results show the severe plastic deformation processing improves the strength of all magnesium alloys, but deformation localization can take place in the Mg-Zn-Ca and Mg-Y-RE alloys. The occurrence of deformation localization is associated with low strain rate sensitivity in these alloys and with severe corrosion localization.

Also, productivity can be improved by reducing times to perform tasks. In the last years, a lot of effort has been invested in research and development of collective control of mobile robots. This interest is justified as there are many advantages when two or more robots are collaborating in a particular task. Some examples are: cleaning toxic waste, transportation and manipulation of objects, exploration, and surveillance, search and rescue. In this work a study of collective movements of mobile robots is presented. A solution of collisions avoidance is developed.

This paper, part of a Teaching Innovation Project, starts from new training requirements that are fit within Undergraduate Thesis Project, a subject that culminate student learning. Undergraduate Thesis Project is current assessment system that weigh the student acquired training in university education. Students should develop a range of cross curricular competences such as public presentation of ideas, problems and solutions both orally and writing in Undergraduate Thesis Project. Specifically, we intend with our innovation proposal to provide resources that enable university students from Teacher Degree in Education Faculty of University of Extremadura (Spain) to develop the cross curricular competence of public speaking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interaction" title="interaction">interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20speaking" title=" public speaking"> public speaking</a>, <a href="https://publications.waset.org/abstracts/search?q=student" title=" student"> student</a>, <a href="https://publications.waset.org/abstracts/search?q=university" title=" university"> university</a> </p> <a href="https://publications.waset.org/abstracts/8668/development-of-cross-curricular-competences-in-university-classrooms-public-speaking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8668.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">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">138</span> Hybridization as a Process of Refusal of Imposed Popular Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Eliseo%20Mu%C3%B1iz-Gutierrez">Jorge Eliseo Muñiz-Gutierrez</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Olvera-Garc%C3%ADa"> Daniel Olvera-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Sotelo-Salas"> Cristina Sotelo-Salas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this research is to allow the understanding of the hybridization process shown in culture through the architecture of mass production for the purpose of consumption, taking as a case study the mass-built housing of the city of Mexicali, Mexico. The methodology is born from the hermeneutical study of the meta-modified architectural object, which guided the research with a qualitative focus to be carried out in two stages, the first is based on the literature review regarding cultural hybridization, and the second stage is carried out in through an ethnographic study of the cultural exploration of the contextual landscape produced by the houses located in popular neighborhoods of the city of Mexicali, Mexico. The research shows that there is an unconscious hybridization process, the birth of a mixture of impositions guided by the popular and the personal aspirations of the inhabitant. The study presents the possibilities of a home and the relationship with its inhabitant and, in turn, its effects on the context and its contribution to culture through hybridization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybridization" title="hybridization">hybridization</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20landscape" title=" architectural landscape"> architectural landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture" title=" architecture"> architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20housing" title=" mass housing"> mass housing</a> </p> <a href="https://publications.waset.org/abstracts/141872/hybridization-as-a-process-of-refusal-of-imposed-popular-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141872.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">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">137</span> Experimental Characterization of the Color Quality and Error Rate for an Red, Green, and Blue-Based Light Emission Diode-Fixture Used in Visible Light Communications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20F.%20Gutierrez">Juan F.

Visible Light Communication (VLC) is a wireless method to transmit data with visible light. Modulation formats such as On-Off Keying (OOK) and Color Shift Keying (CSK) are used in VLC. Since CSK is based on three color bands uses red, green, and blue monochromatic LED (RGB-LED) to define a pattern of chromaticities. This type of CSK provides poor color quality in the illuminated area. This work presents the design and implementation of a VLC system using RGB-based CSK with 16, 8, and 4 color points, mixing with a steady baseline of a phosphor white-LED, to improve the color quality of the LED-Fixture. The experimental system was assessed in terms of the Color Rendering Index (CRI) and the Symbol Error Rate (SER). Good color quality performance of the LED-Fixture was obtained with an acceptable SER. The laboratory setup used to characterize and calibrate an LED-Fixture is described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VLC" title="VLC">VLC</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20lighting" title=" indoor lighting"> indoor lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=color%20quality" title=" color quality"> color quality</a>, <a href="https://publications.waset.org/abstracts/search?q=symbol%20error%20rate" title=" symbol error rate"> symbol error rate</a>, <a href="https://publications.waset.org/abstracts/search?q=color%20shift%20keying" title=" color shift keying"> color shift keying</a> </p> <a href="https://publications.waset.org/abstracts/158336/experimental-characterization-of-the-color-quality-and-error-rate-for-an-red-green-and-blue-based-light-emission-diode-fixture-used-in-visible-light-communications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158336.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">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> Umbilical Epidermal Inclusion Cysts, a Rare Cause of Umbilical Mass: A Case Report and Review of Literature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christine%20Li">Christine Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Robertson"> Amanda Robertson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Epidermal inclusion cysts occur when epidermal cells are implanted in the dermis following trauma, or surgery. They are a rare cause of an umbilical mass, with very few cases previously reported following abdominal surgery. These lesions can present with a range of symptoms, including palpable mass, pain, redness, or discharge. This paper reports a case of an umbilical epidermal inclusion cyst in a 52-year-old female presenting with a six-week history of a painful, red umbilical lump on a background of two previous diagnostic laparoscopies. Abdominal computed tomography (CT) scans revealed non-specific soft tissue thickening in the umbilical region. This was successfully treated with complete excision of the lesion. Umbilical lumps are a common presentation but can represent a diagnostic challenge. The differential diagnosis should include an epidermal inclusion cyst, particularly in a patient who has had previous abdominal surgery, including laparoscopic surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epidermal%20inclusion%20cyst" title="epidermal inclusion cyst">epidermal inclusion cyst</a>, <a href="https://publications.waset.org/abstracts/search?q=laparoscopy" title=" laparoscopy"> laparoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilical%20mass" title=" umbilical mass"> umbilical mass</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilicus" title=" umbilicus"> umbilicus</a> </p> <a href="https://publications.waset.org/abstracts/138636/umbilical-epidermal-inclusion-cysts-a-rare-cause-of-umbilical-mass-a-case-report-and-review-of-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138636.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">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">135</span> Effect of Wetting Layer on the Energy Spectrum of One-Electron Non-Uniform Quantum Ring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20A.%20Rodr%C3%ADguez-Prada">F.

We show that in the adiabatic limit, when the crater thickness is much smaller than its lateral dimension, the one-particle wave functions of the electron confined in such structure in the zero magnetic field case can be found exactly in an analytical form and they can be used subsequently as the base functions in framework of the exact diagonalization method to study the effect of the wetting layer and an external magnetic field applied along of the grown axis on energy levels of one-electron non-uniform quantum dot. It is shown that both the structural non-uniformity and the increase of the thickness of the wetting layer provide a quenching of the Aharonov-Bohm oscillations of the lower energy levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20properties" title="electronic properties">electronic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20rings" title=" quantum rings"> quantum rings</a>, <a href="https://publications.waset.org/abstracts/search?q=volcano%20shaped" title=" volcano shaped"> volcano shaped</a>, <a href="https://publications.waset.org/abstracts/search?q=wetting%20layer" title=" wetting layer"> wetting layer</a> </p> <a href="https://publications.waset.org/abstracts/34102/effect-of-wetting-layer-on-the-energy-spectrum-of-one-electron-non-uniform-quantum-ring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34102.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">134</span> The Many Faces of Cancer and Knowing When to Say Stop</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diwei%20Lin">Diwei Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Jh.%20Tan"> Amanda Jh.

While NE tumours account for 1% to 5% of all cases of prostate cancer and scattered NE cells can be found in 10% to 100% of prostate adenocarcinomas, pure LCNEC of the prostate is extremely rare. Most LCNEC of the prostate is thought to originate by clonal progression under the selection pressure of therapy and refractory to long-term hormonal treatment for adenocarcinoma of the prostate. De novo LCNEC is only described in case reports and is thought to develop via direct malignant transformation. Limited data in the English literature makes it difficult to accurately predict the prognosis of LCNEC of the prostate. However, current evidence suggesting that increasing NE differentiation in prostate adenocarcinoma is associated with a higher stage, high-grade disease, and a worse prognosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=large%20cell%20neuroendocrine%20cancer" title="large cell neuroendocrine cancer">large cell neuroendocrine cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=refractory%20cancer" title=" refractory cancer"> refractory cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20and%20health%20sciences" title=" medical and health sciences"> medical and health sciences</a> </p> <a href="https://publications.waset.org/abstracts/10859/the-many-faces-of-cancer-and-knowing-when-to-say-stop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10859.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">421</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">133</span> Experimental Approach for Determining Hemi-Anechoic Characteristics of Engineering Acoustical Test Chambers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Montoya-Ospina">Santiago Montoya-Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20E.%20Jim%C3%A9nez-Mej%C3%ADa"> Raúl E.

The method was based on the bibliographic review of articles published in databases such as SciELO and Pubmed. In the discussion, historical and humanistic aspects that contributed to the construction of a genocidal culture practiced during this period were analyzed. Additionally, an ethical question arises: should the information acquired during this dark period be used by science? After analysis, it was found that these Nazi experiments went over medical and ethical principles, being a deplorable milestone in history. It was also concluded that, although they generated potentially 'useful' results in the scientific field, they should be discarded as an ethical question of principle, of never daring to validate such a deplorable way of obtaining knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazism" title="Nazism">Nazism</a>, <a href="https://publications.waset.org/abstracts/search?q=bioethics" title=" bioethics"> bioethics</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20experimentation" title=" human experimentation"> human experimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=genocide" title=" genocide"> genocide</a>, <a href="https://publications.waset.org/abstracts/search?q=torture" title=" torture"> torture</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a> </p> <a href="https://publications.waset.org/abstracts/133246/nazi-experiments-during-world-war-ii-dismal-period-for-bioethics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133246.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Determination of the Optimal Content of Commercial Superplasticizer Additives in Cements with Calcined Clay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20R.%20Teixeira">Amanda R.

These compounds act at the solid-liquid interface of colloidal suspensions of cement pastes, preventing agglomeration of the particles. Although the use in the concrete industry is wide, the mechanisms of dispersion of concrete admixtures composed of polycarboxylate in cement with supplementary cementitious materials have ample opportunity to be investigated, providing the attainment of increasingly compatible and efficient cement-addition-additive systems. The cements used in the research are Portland Cement CPV and two cements Portland Cement Composite (CPIV) with calcined clay contents of 20% and 28% and three commercial additives based on polycarboxylate. The performance of the additives and obtaining the optimal content was determined by the Marsh Cone test and spread by Mini-Slump. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcined%20clay" title="calcined clay">calcined clay</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20cements" title=" composite cements"> composite cements</a>, <a href="https://publications.waset.org/abstracts/search?q=superplasticizer%20additives" title=" superplasticizer additives"> superplasticizer additives</a>, <a href="https://publications.waset.org/abstracts/search?q=polycarboxylate" title=" polycarboxylate"> polycarboxylate</a> </p> <a href="https://publications.waset.org/abstracts/159324/determination-of-the-optimal-content-of-commercial-superplasticizer-additives-in-cements-with-calcined-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159324.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">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">129</span> Phase Diagrams and Liquid-Liquid Extraction in Aqueous Biphasic Systems Formed by Polyethylene Glycol and Potassium Sodium Tartrate at 303.15 K</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Cristina%20de%20Oliveira">Amanda Cristina de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20de%20Souza%20Monteiro%20Filho"> Elias de Souza Monteiro Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberta%20Ceriani"> Roberta Ceriani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Liquid-liquid extraction in aqueous two-phase systems (ATPSs) constitutes a powerful tool for purifying bio-materials, such as cells, organelles, proteins, among others. In this work, the extraction of the bovine serum albumin (BSA) has been studied in systems formed by polyethylene glycol (PEG) (1500, 4000, and 6000 g.mol⁻¹) + potassium sodium tartrate + water at 303.15°K. Phase diagrams were obtained by turbidimetry and Merchuk’s method (1998). The experimental tie-lines were described using the Othmer-Tobias and Bancroft correlations. ATPSs were correlated with the nonrandom two-liquid (NRTL) model. The results were considered excellent according to global root-mean-square deviations found which were between 0,72 and 1,13%. The concentrations of the proteins in each phase were determined by spectrophotometry at 280 nm, finding partition efficiencies greater than 71%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aqueous%20two%20phases%20systems" title="aqueous two phases systems">aqueous two phases systems</a>, <a href="https://publications.waset.org/abstracts/search?q=bovine%20serum%20albumin" title=" bovine serum albumin "> bovine serum albumin </a>, <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20extraction" title=" liquid-liquid extraction"> liquid-liquid extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene%20glycol" title=" polyethylene glycol"> polyethylene glycol</a> </p> <a href="https://publications.waset.org/abstracts/103304/phase-diagrams-and-liquid-liquid-extraction-in-aqueous-biphasic-systems-formed-by-polyethylene-glycol-and-potassium-sodium-tartrate-at-30315-k" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103304.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">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">128</span> Study of Atmospheric Cascades Generated by Primary Comic Rays, from Simulations in Corsika for the City of Tunja in Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tathiana%20Yesenia%20Coy%20Mondrag%C3%B3n">Tathiana Yesenia Coy Mondragón</a>, <a href="https://publications.waset.org/abstracts/search?q=Jossitt%20William%20Vargas%20Cruz"> Jossitt William Vargas Cruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Leonardo%20Guti%C3%A9rrez%20G%C3%B3mez"> Cristian Leonardo Gutiérrez Gómez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of cosmic rays is based on two fundamental pillars: the detection of secondary cosmic rays on the Earth's surface and the detection of the source and origin of the cascade. In addition, the constant flow of RC generates a lot of interest for study due to the incidence of various natural phenomena, which makes it relevant to characterize their incidence parameters to determine their effect not only at subsoil or terrestrial surface levels but also throughout the atmosphere. To determine the physical parameters of the primary cosmic ray, the implementation of robust algorithms capable of reconstructing the cascade from the measured values is required, with a high level of reliability. Therefore, it is proposed to build a machine learning system that will be fed from the cosmic ray simulations in CORSIKA at different energies that lie in a range [10⁹-10¹²] eV. in order to generate a trained particle and pattern recognition system to obtain greater efficiency when inferring the nature of the origin of the cascade for EAS in the atmosphere considering atmospheric models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CORSIKA" title="CORSIKA">CORSIKA</a>, <a href="https://publications.waset.org/abstracts/search?q=cosmic%20rays" title=" cosmic rays"> cosmic rays</a>, <a href="https://publications.waset.org/abstracts/search?q=eas" title=" eas"> eas</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/163412/study-of-atmospheric-cascades-generated-by-primary-comic-rays-from-simulations-in-corsika-for-the-city-of-tunja-in-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163412.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">127</span> Behavior of Current in a Semiconductor Nanostructure under Influence of Embedded Quantum Dots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Paredes%20Guti%C3%A9rrez">H.

We work with a general theory of quantum transport that accounts the tight-binding model for the spin dependent resonant tunneling in a semiconductor nanostructure, and Rashba spin orbital to study the spin orbit coupling. In this context, we use the second quantization theory for Rashba effect and the standard Green functions method. We calculate the current density as a function of the voltage without and in the presence of quantum dots. In the second case, we considered the size and shape of the quantum dot, and in the two cases, we worked considering the spin polarization affected by external electric fields. We found that the EQD generates significant changes in current when we consider different morphologies of EQD, as those described above. The first thing shown is that the current decreases significantly, such as the geometry of EQD is changed, prevailing the geometrical confinement. Likewise, we see that the current density decreases when the voltage is increased, showing that the quantum system studied here is more efficient when the morphology of the quantum dot changes. <p
