synthesis, characterization and applications of new nanocomposite materials based on silica mesoporous nanocompozites systems. The nanocomposite support was obtained by using a specific step–by–step multilayer structure buildup synthetic route, characterized by XRD (X-Ray Difraction), TEM (Transmission Electron Microscopy), FT-IR (Fourier Transform-Infra Red Spectrometry), BET (Brunauer–Emmett–Teller method) and loaded with Salvia officinalis plant extract obtained by a hydro-alcoholic extraction route. The sustained release of the target compounds was studied by a modified LC method, proving low release profiles, as expected for the high specific surface area support. The obtained results were further correlated with the in vitro / in vivo behavior of the nanocomposite material and recommending the silica mesoporous nanocomposites as good candidates for biomedical applications.

Snacking habits, including eating whole fruit, vegetables and crackers, were found to contribute to better overall diet quality, while consuming snacks such as cookies, pastries, sweets, milk desserts and soft drinks was associated with poorer diet quality. The nutritional quality of the snack is very important and choosing nutritious foods as snacks can be beneficial for our health. For this reason, the development of functional snacks bars represents a necessity for this niche market. The aim of this work was to develop some formulations of energizing snack bars with high dietary fibers and antioxidant activity. Snack bars contain both fruits with antioxidant activity and components (cereals and seeds) rich in carbohydrates and polyunsaturated fats that provide energy during sports activities, physical and mental stress. Three types of samples were prepared and stored in refrigerated conditions at 40°C for 30 days. The first sample (S1) contains wheat germs, raw pumpkin seeds, toasted oat flakes, flaxseeds flour, cinnamon honey, raw sunflower seeds, sea buckthorn, amaranth flour, cinnamon and olive oil. The second sample (S2) has the same composition as the first, less flour and cinnamon flour and the honey used was ginger, honey. The third sample (S3) is like the first less amaranth flour and the honey used was buckthorn sea honey. The physicochemical, antioxidant activity, polyphenolic and flavonoid content and sensorial characteristics of the samples were investigated. Results showed that snacks bars had important level of extracted phenolics, flavonoids, fibers, proteins, carbohydrates and fats. Therefore, snack bars may be a convenient functional food, offering an important source of flavonoids and polyphenols, a healthy alternative to a poor diet quality, with balanced nutritional and sensory characteristics that recommend it in the diet of all consumers concerned with maintaining health.

Due to the content of essential compounds such as antioxidants, important amounts of fruits and vegetables should be included in the daily diet. Juices are good sources of vitamins and can also help increase overall fruit and vegetable consumption. Starting from this trend (introduction into the daily diet of vegetables and fruits) as well as the desire to diversify the range of functional products for both adults and children, a fermented juice was made using probiotic microorganisms based on root vegetables, with potential beneficial effects in the diet of children, vegetarians and people with lactose intolerance. The three vegetables selected for this study, red beet, carrot, and celery bring a significant contribution to functional compounds such as carotenoids, flavonoids, betalain, vitamin B and C, minerals and fiber. By fermentation, the functional value of the vegetable juice increases due to the improved stability of these compounds. The combination of probiotic microorganisms and vegetable fibers resulted in a nutrient-rich synbiotic product. The stability of the nutritional and sensory qualities of the obtained synbiotic product has been tested throughout its shelf life. The evaluation of the physico-chemical changes of the synbiotic drink during storage confirmed that: (i) vegetable juice enriched with honey and vegetable pulp is an important source of nutritional compounds, especially carbohydrates and fiber; (ii) microwave treatment used to inhibit pathogenic microflora did not significantly affect nutritional compounds in vegetable juice, vitamin C concentration remained at baseline and beta-carotene concentration increased due to increased bioavailability; (iii) fermentation has improved the nutritional quality of vegetable juice by increasing the content of B vitamins, polyphenols and flavonoids and has a good antioxidant capacity throughout the shelf life; (iv) the FTIR and Raman spectra have highlighted the results obtained using physicochemical methods. Based on the analysis of IR absorption frequencies, the most striking bands belong to the frequencies 3330 cm⁻¹, 1636 cm⁻¹ and 1050 cm⁻¹, specific for groups of compounds such as polyphenols, carbohydrates, fatty acids, and proteins. Statistical data processing revealed a good correlation between the content of flavonoids, betalain, β-carotene, ascorbic acid and polyphenols, the fermented juice having a stable antioxidant activity. Also, principal components analysis showed that there was a negative correlation between the evolution of the concentration of B vitamins and antioxidant activity.

Climate models project scenarios of precipitation changes in the future, considering greenhouse emissions. In this study, the EURO-CORDEX (European Coordinated Regional Downscaling Experiment) climate models were first evaluated in a Mediterranean island (Sardinia) against observed precipitation for a historical reference period (1976-2005). A weighted multi-model ensemble (ENS) was built, weighting the single models based on their ability to reproduce observed rainfall. Future projections (2071-2100) were carried out using the 8.5 RCP emissions scenario to evaluate changes in precipitations. ENS was then used as climate forcing for the SWAT model (Soil and Water Assessment Tool), with the aim to assess the consequences of such projected changes on streamflow and runoff of two small catchments located in the South-West Sardinia. Results showed that a decrease of mean rainfall values, up to -25 % at yearly scale, is expected for the future, along with an increase of extreme precipitation events. Particularly in the eastern and southern areas, extreme events are projected to increase by 30%. Such changes reflect on the hydrologic cycle with a decrease of mean streamflow and runoff, except in spring, when runoff is projected to increase by 20-30%. These results stress that the Mediterranean is a hotspot for climate change, and the use of model tools can provide very useful information to adopt water and land management strategies to deal with such changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EURO-CORDEX" title="EURO-CORDEX">EURO-CORDEX</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrology" title=" hydrology"> hydrology</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT%20model" title=" SWAT model"> SWAT model</a>, <a href="https://publications.waset.org/abstracts/search?q=Sardinia" title=" Sardinia"> Sardinia</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-model%20ensemble" title=" multi-model ensemble"> multi-model ensemble</a> </p> <a href="https://publications.waset.org/abstracts/141817/climate-change-effects-in-a-mediterranean-island-and-streamflow-changes-for-a-small-basin-using-euro-cordex-regional-climate-simulations-combined-with-the-swat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141817.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">213</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> The Judge Citizens Have in Mind, Comparative Lessons about the Rule of Law Matrix</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Piana">Daniela Piana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work casts light on what lies underneath the rule of law.

The first one is a pars destruens: the mainstreaming scholarship on judicial independence and judicial accountability is questioned under the large amount of data we have at our disposal (this step is accomplished in the first two paragraphs). The second step is the reframe of the concept of the rule of law and the consequent rise of a hidden dimension, which has been so far largely underexplored: responsiveness. The third step consists into offering the readers empirical support and drawing thereby consequences in terms of policy design and citizens engagement into the rule of law implementation (these two steps are accomplished in the third paragraph). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rule%20of%20law" title="rule of law">rule of law</a>, <a href="https://publications.waset.org/abstracts/search?q=accountability" title=" accountability"> accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=citizens" title=" citizens"> citizens</a> </p> <a href="https://publications.waset.org/abstracts/47609/the-judge-citizens-have-in-mind-comparative-lessons-about-the-rule-of-law-matrix" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47609.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">248</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">106</span> ESDN Expression in the Tumor Microenvironment Coordinates Melanoma Progression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Coppo">Roberto Coppo</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Orso"> Francesca Orso</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Dettori"> Daniela Dettori</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Quaglino"> Elena Quaglino</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Nie"> Lei Nie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20M.%20Sadeghi"> Mehran M.

Several research studies in recent years have provided evidence that cancer initiation and progression are driven by genetic alterations of the tumor and paracrine interactions between tumor and microenvironment. Scattered data show that the Endothelial and Smooth muscle cell-Derived Neuropilin-like molecule (ESDN) controls cell proliferation and movement of stroma and tumor cells. To investigate the role of ESDN in the tumor microenvironment during melanoma progression, murine melanoma cells (B16 or B16-F10) were injected in ESDN knockout mice in order to evaluate how the absence of ESDN in stromal cells could influence melanoma progression. While no effect was found on primary tumor growth, increased cell extravasation and lung metastasis formation was observed in ESDN knockout mice compared to wild type controls. In order to understand how cancer cells cross the endothelial barrier during metastatic dissemination in an ESDN-null microenvironment, structure, and permeability of lung blood vessels were analyzed. Interestingly, ESDN knockout mice showed structurally altered and more permeable vessels compared to wild type animals. Since cell surface molecules mediate the process of tumor cell extravasation, the expression of a panel of extravasation-related ligands and receptors was analyzed. Importantly, modulations of N-cadherin, E-selectin, ICAM-1 and VAP-1 were observed in ESDN knockout endothelial cells, suggesting the presence of a favorable tumor microenvironment which facilitates melanoma cell extravasation and metastasis formation in the absence of ESDN. Furthermore, a potential contribution of immune cells in tumor dissemination was investigated. An increased recruitment of macrophages in the lungs of ESDN knockout mice carrying subcutaneous B16-F10 tumors was found. In conclusion, our data suggest a functional role of ESDN in the tumor microenvironment during melanoma progression and the identification of the mechanisms that regulate tumor cell extravasation could lead to the development of new therapies to reduce metastasis formation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melanoma" title="melanoma">melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20microenvironment" title=" tumor microenvironment"> tumor microenvironment</a>, <a href="https://publications.waset.org/abstracts/search?q=extravasation" title=" extravasation"> extravasation</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20surface%20molecules" title=" cell surface molecules"> cell surface molecules</a> </p> <a href="https://publications.waset.org/abstracts/44830/esdn-expression-in-the-tumor-microenvironment-coordinates-melanoma-progression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44830.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">334</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">105</span> Preliminary Analysis of a Phylogeography Study of Dendropsophus minutus in the Guiana Shield</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mera-Mart%C3%ADnez%20Daniela">Mera-Martínez Daniela</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dendropsophus minutus, is a species distributed in South America including the slopes of the Andes, the Amazon basin, forests of southeastern Brazil and in Guyana where tropical forests are characteristic.

It was evidenced that there is a haplotypic difference in the locality of Guyana compared to Suriname and French Guyana, but this does not have a correlation with the geographic distance, but this one can be influenced by the conditions of the places. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phylogeography" title="phylogeography">phylogeography</a>, <a href="https://publications.waset.org/abstracts/search?q=Dendropsophus" title=" Dendropsophus"> Dendropsophus</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20distance" title=" geographic distance"> geographic distance</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20markers" title=" molecular markers"> molecular markers</a> </p> <a href="https://publications.waset.org/abstracts/78676/preliminary-analysis-of-a-phylogeography-study-of-dendropsophus-minutus-in-the-guiana-shield" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78676.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">104</span> Slow Pyrolysis of Bio-Wastes: Environmental, Exergetic, and Energetic (3E) Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Zalazar-Garcia">Daniela Zalazar-Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20Torres"> Erick Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=German%20Mazza"> German Mazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Slow pyrolysis of a pellet of pistachio waste was studied using a lab-scale stainless-steel reactor. Experiments were conducted at different heating rates (5, 10, and 15 K/min). A 3-E (environmental, exergetic, and energetic) analysis for the processing of 20 kg/h of bio-waste was carried out. Experimental results showed that biochar and gas yields decreased with an increase in the heating rate (43 to 36 % and 28 to 24 %, respectively), while the bio-oil yield increased (29 to 40 %). Finally, from the 3-E analysis and the experimental results, it can be suggested that an increase in the heating rate resulted in a higher pyrolysis exergetic efficiency (70 %) due to an increase of the bio-oil yield with high-energy content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3E%20assessment" title="3E assessment">3E assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-waste%20pellet" title=" bio-waste pellet"> bio-waste pellet</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=slow%20pyrolysis" title=" slow pyrolysis"> slow pyrolysis</a> </p> <a href="https://publications.waset.org/abstracts/139075/slow-pyrolysis-of-bio-wastes-environmental-exergetic-and-energetic-3e-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139075.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">220</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">103</span> Current Cosmetic Treatments in Pregnancy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20F.%20Maluf">Daniela F.

An important part of the HMI system is the ability to monitor the level of situational awareness (SA) of any driver in real-time, in different scenarios, and without any pre-calibration. Presenting state-of-the-art machine learning models used to measure SA is the purpose of this systematic review. Investigating the limitations of each type of sensor, the gaps, and the most suited sensor and computational model that can be used in driving applications. To the author’s best knowledge this is the first literature review identifying online and offline classification methods used to measure SA, explaining which measurements are subject or session-specific, and how many classifications can be done with each classification model. This information can be very useful for researchers measuring SA to identify the most suited model to measure SA for different applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=situational%20awareness" title="situational awareness">situational awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20driving" title=" autonomous driving"> autonomous driving</a>, <a href="https://publications.waset.org/abstracts/search?q=gaze%20metrics" title=" gaze metrics"> gaze metrics</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=ECG" title=" ECG"> ECG</a> </p> <a href="https://publications.waset.org/abstracts/157210/a-systematic-review-of-situational-awareness-and-cognitive-load-measurement-in-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157210.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">99</span> The Industrial Property in the Context of Wine Production in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F%C3%A1tima%20R.%20Zan">Fátima R.

It was developed using the mathematical model of the robotic arm, thus defining the parameters for virtual recreation. The environment, interaction, and behavior of the robotic arm were developed in a graphic engine (Unity3D) to emulate learning tasks such as in a robotics laboratory. In the virtual system, four inputs were developed for the movement of the robot arm; further, to program the robot, a user interface was created where the user selects the trajectory such as point to point, line, arc, or circle. Finally, the hypothesis of the industrial robotic learning process is validated through the level of knowledge acquired after using the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20learning" title="virtual learning">virtual learning</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20arm" title=" robot arm"> robot arm</a>, <a href="https://publications.waset.org/abstracts/search?q=non-immersive%20reality" title=" non-immersive reality"> non-immersive reality</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a> </p> <a href="https://publications.waset.org/abstracts/145376/non-immersive-virtual-laboratory-applied-to-robotics-arms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145376.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">97</span> Numerical Methods for Topological Optimization of Wooden Structural Elements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Tapusi">Daniela Tapusi</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Andronic"> Adrian Andronic</a>, <a href="https://publications.waset.org/abstracts/search?q=Naomi%20Tufan"> Naomi Tufan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruxandra%20Erba%C8%99u"> Ruxandra Erbașu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioana%20Teodorescu"> Ioana Teodorescu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The proposed theme of this article falls within the policy of reducing carbon emissions imposed by the ‘Green New Deal’ by replacing structural elements made of energy-intensive materials with ecological materials. In this sense, wood has many qualities (high strength/mass and stiffness/mass ratio, low specific gravity, recovery/recycling) that make it competitive with classic building materials. The topological optimization of the linear glulam elements, resulting from different types of analysis (Finite Element Method, simple regression on metamodels), tests on models or by Monte-Carlo simulation, leads to a material reduction of more than 10%.

In this way, a study was done to determine the phenolic composition (total phenols, anthocyanins and tannins) and antioxidant activity of blueberries from three cultivars (Duke, Bluecrop, and Ozarblue) grown in two different Portuguese farms. Initially two successive extractions were done with methanol followed by two extractions with aqueous acetone solutions. These extracts obtained were then used to evaluate the amount of phenolic compounds and the antioxidant activity. The total phenols were observed to vary from 4.9 to 8.2 mg GAE/g fresh weight, with anthocyanin’s contents in the range 1.5-2.8 mg EMv3G/g and tannins contents in the range 1.5- 3.8 mg/g. The results for antioxidant activity ranged from 9.3 to 23.2 mol TE/g, and from 24.7 to 53.4 mol TE/g, when measured, respectively, by DPPH and ABTS methods. In conclusion it was observed that, in general, the cultivar had a visible effect on the phenols present, and furthermore, the geographical origin showed relevance either in the phenols contents or the antioxidant activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthocyanins" title="anthocyanins">anthocyanins</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=blueberry%20cultivar" title=" blueberry cultivar"> blueberry cultivar</a>, <a href="https://publications.waset.org/abstracts/search?q=geographical%20origin" title=" geographical origin"> geographical origin</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a> </p> <a href="https://publications.waset.org/abstracts/22045/evaluation-of-bioactive-phenols-in-blueberries-from-different-cultivars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22045.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">474</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">95</span> Strategic Tools for Entrepreneurship: Model Proposal for Manufacturing Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Mansanta">Chiara Mansanta</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Sani"> Daniela Sani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper presents the further development of the application of a standard methodology to boost innovation inside real case studies of manufacturing companies. The proposed methodology provides a viable solution for manufacturing companies that have to evaluate new business ideas. The study underlined the concept of entrepreneurship and how a manager can use it to promote innovation inside their companies. Starting from a literature study on entrepreneurship, this paper examines the role of the manager in supporting a company’s development. The empirical part of the study is based on two manufacturing companies that used the proposed methodology to favour entrepreneurship through an alternative approach. The research demonstrated the need for companies to have a structured and well-defined methodology to achieve their goals. The purpose of this article is to understand the significance of business models inside companies and explore how they affect business strategy and innovation management. The idea is to use business models to support entrepreneurs in their decision-making processes, reducing risks and avoiding errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20companies" title=" manufacturing companies"> manufacturing companies</a>, <a href="https://publications.waset.org/abstracts/search?q=solution%20validation" title=" solution validation"> solution validation</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20management" title=" strategic management"> strategic management</a> </p> <a href="https://publications.waset.org/abstracts/164943/strategic-tools-for-entrepreneurship-model-proposal-for-manufacturing-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164943.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">95</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> A Method for Reduction of Association Rules in Data Mining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20De%20Castro%20Rodrigues">Diego De Castro Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Lisboa%20Rocha"> Marcelo Lisboa Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20M.%20De%20Q.%20Trevisan"> Daniela M.

Very often, the number of rules generated is high, sometimes even in databases with small volume, so the success in the analysis of results can be hampered by this quantity. The purpose of this research is to present a method for reducing the quantity of rules generated with association algorithms. Therefore, a computational algorithm was developed with the use of a Weka Application Programming Interface, which allows the execution of the method on different types of databases. After the development, tests were carried out on three types of databases: synthetic, model, and real. Efficient results were obtained in reducing the number of rules, where the worst case presented a gain of more than 50%, considering the concepts of support, confidence, and lift as measures. This study concluded that the proposed model is feasible and quite interesting, contributing to the analysis of the results of association rules generated from the use of algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title="data mining">data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=association%20rules" title=" association rules"> association rules</a>, <a href="https://publications.waset.org/abstracts/search?q=rules%20reduction" title=" rules reduction"> rules reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/110517/a-method-for-reduction-of-association-rules-in-data-mining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110517.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">160</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> Genetic Algorithms Based ACPS Safety</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emine%20Laarouchi">Emine Laarouchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Cancila"> Daniela Cancila</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Soulier"> Laurent Soulier</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakima%20Chaouchi"> Hakima Chaouchi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cyber-Physical Systems as drones proved their efficiency for supporting emergency applications. For these particular applications, travel time and autonomous navigation algorithms are of paramount importance, especially when missions are performed in urban environments with high obstacle density. In this context, however, safety properties are not properly addressed. Our ambition is to optimize the system safety level under autonomous navigation systems, by preserving performance of the CPS. At this aim, we introduce genetic algorithms in the autonomous navigation process of the drone to better infer its trajectory considering the possible obstacles. We first model the wished safety requirements through a cost function and then seek to optimize it though genetics algorithms (GA). The main advantage in the use of GA is to consider different parameters together, for example, the level of battery for navigation system selection. Our tests show that the GA introduction in the autonomous navigation systems minimize the risk of safety lossless. Finally, although our simulation has been tested for autonomous drones, our approach and results could be extended for other autonomous navigation systems such as autonomous cars, robots, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safety" title="safety">safety</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicles" title=" unmanned aerial vehicles "> unmanned aerial vehicles </a>, <a href="https://publications.waset.org/abstracts/search?q=CPS" title=" CPS"> CPS</a>, <a href="https://publications.waset.org/abstracts/search?q=ACPS" title=" ACPS"> ACPS</a>, <a href="https://publications.waset.org/abstracts/search?q=drones" title=" drones"> drones</a>, <a href="https://publications.waset.org/abstracts/search?q=path%20planning" title=" path planning"> path planning</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithms" title=" genetic algorithms"> genetic algorithms</a> </p> <a href="https://publications.waset.org/abstracts/117828/genetic-algorithms-based-acps-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117828.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">181</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> Statistical Analysis of the Factors that Influence the Properties of Blueberries from Cultivar Bluecrop</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raquel%20P.%20F.%20Guin%C3%A9">Raquel P.

Hence this work was undertaken to evaluate the effect of some production and conservation factors on the properties of blueberries from cultivar Bluecrop. The physical and chemical analyses were done according to established methodologies and then all data was treated using software SPSS for assessment of the possible differences among the factors investigated and/or the correlations between the variables at study. The results showed that location of production influenced some of the berries properties (caliber, sugars, antioxidant activity, color and texture) and that the age of the bushes was correlated with moisture, sugars and acidity, as well as lightness. On the other hand, altitude of the farm only was correlated to sugar content. With regards to conservation, it influenced only anthocyanins content and DPPH antioxidant activity. Finally, the type of extract and the order of extraction had a pronounced influence on all the phnolic properties evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antioxidant%20activity" title="Antioxidant activity">Antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=blueberry" title=" blueberry"> blueberry</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=geographical%20origin" title=" geographical origin"> geographical origin</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a> </p> <a href="https://publications.waset.org/abstracts/30676/statistical-analysis-of-the-factors-that-influence-the-properties-of-blueberries-from-cultivar-bluecrop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30676.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">476</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">91</span> Hydroxyapatite-Chitosan Composites for Tissue Engineering Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgeta%20Voicu">Georgeta Voicu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Daniela%20Ghitulica"> Cristina Daniela Ghitulica</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreia%20Cucuruz"> Andreia Cucuruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Busuioc"> Cristina Busuioc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the field of tissue engineering, the compositional and microstructural features of the employed materials play an important role, with implications on the mechanical and biological behaviour of the medical devices. In this context, the development of apatite - natural biopolymer composites represents a choice of many scientific groups. Thus, hydroxyapatite powders were synthesized by a wet method, namely co-precipitation, starting from high purity reagents (CaO, MgO, and H3PO4). Moreover, the substitution of calcium with magnesium have been approached, in the 5 - 10 wt.% range. Afterward, the phosphate powders were integrated in two types of composites with chitosan, different from morphological point of view. First, 3D porous scaffolds were obtained by a freeze-drying procedure. Second, uniform, compact films were achieved by film casting. The influence of chitosan molecular weight (low, medium and high), as well as apatite powder to polymer ratio (1:1 and 1:2) on the morphological properties, were analysed in detail. In conclusion, the reported biocomposites, prepared by a straightforward route are suitable for bone substitution or repairing applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20reconstruction" title="bone reconstruction">bone reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20scaffolds" title=" composite scaffolds"> composite scaffolds</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a> </p> <a href="https://publications.waset.org/abstracts/62705/hydroxyapatite-chitosan-composites-for-tissue-engineering-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62705.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">322</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> A Versatile Algorithm to Propose Optimized Solutions to the Dengue Disease Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fernando%20L.%20P.%20Santos">Fernando L.

It is transmitted by the bite of mosquitoes, usually of the genus Aedes aegypti. It occurs in tropical and subtropical areas of the world. This disease has been a major public health problem worldwide, especially in tropical countries such as Brazil, and its incidence has increased in recent years. Dengue is a subject of intense research. Efficient forms of mosquito control must be considered. In this work, the mono-objective optimal control problem was solved for analysing the dengue disease problem. Chemical and biological controls were considered in the mathematical aspect. This model describes the dynamics of mosquitoes in water and winged phases. We applied the genetic algorithms (GA) to obtain optimal strategies for the control of dengue. Numerical simulations have been performed to verify the versatility and the applicability of this algorithm. On the basis of the present results we may recommend the GA to solve optimal control problem with a large region of feasibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=dengue" title=" dengue"> dengue</a>, <a href="https://publications.waset.org/abstracts/search?q=Aedes%20aegypti" title=" Aedes aegypti"> Aedes aegypti</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title=" biological control"> biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20control" title=" chemical control"> chemical control</a> </p> <a href="https://publications.waset.org/abstracts/15232/a-versatile-algorithm-to-propose-optimized-solutions-to-the-dengue-disease-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15232.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">349</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> Negative RT-PCR in a Newborn Infected with Zika Virus: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vallejo%20Michael">Vallejo Michael</a>, <a href="https://publications.waset.org/abstracts/search?q=Acu%C3%B1a%20Edgar"> Acuña Edgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Roa%20Juan%20David"> Roa Juan David</a>, <a href="https://publications.waset.org/abstracts/search?q=Pe%C3%B1uela%20Rosa"> Peñuela Rosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Parra%20Alejandra"> Parra Alejandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Casallas%20Daniela"> Casallas Daniela</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodriguez%20Sheyla"> Rodriguez Sheyla </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Congenital Zika Virus Syndrome is an entity composed by a variety of birth defects presented in newborns that have been exposed to the Zika Virus during pregnancy. The syndrome characteristic features are severe microcephaly, cerebral tissue abnormalities, ophthalmological abnormalities such as uveitis and chorioretinitis, arthrogryposis, clubfoot deformity and muscular tone abnormalities. The confirmatory test is the Reverse transcription polymerase chain reaction (RT-PCR) associated to the physical findings. Here we present the case of a newborn with microcephaly whose mother presented a confirmed Zika Virus infection during the third trimester of pregnancy, despite of the evident findings and the history of Zika infection the RT-PCR in amniotic and cerebrospinal fluid of the newborn was negative. RT-PCR has demonstrated a low sensibility in samples with low viral loads, reason why, we propose a clinical diagnosis in patients with clinical history of Zika Virus infection during pregnancy accompanied by evident clinical manifestations of the child. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congenital" title="congenital">congenital</a>, <a href="https://publications.waset.org/abstracts/search?q=Zika%20virus" title=" Zika virus"> Zika virus</a>, <a href="https://publications.waset.org/abstracts/search?q=microcephaly" title=" microcephaly"> microcephaly</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20transcriptase%20polymerase%20chain%20reaction" title=" reverse transcriptase polymerase chain reaction"> reverse transcriptase polymerase chain reaction</a> </p> <a href="https://publications.waset.org/abstracts/84563/negative-rt-pcr-in-a-newborn-infected-with-zika-virus-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84563.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">211</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> Friction Calculation and Simulation of Column Electric Power Steering System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamid%20Mirmohammad%20Sadeghi">Seyed Hamid Mirmohammad Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaella%20Sesana"> Raffaella Sesana</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Maffiodo"> Daniela Maffiodo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a procedure for friction calculation of column electric power steering (C-EPS) system which affects handling and comfort in driving. The friction losses estimation is obtained from experimental tests and mathematical calculation. Parts in C-EPS mainly involved in friction losses are bearings and worm gear. In the theoretical approach, the gear geometry and Hertz law were employed to measure the normal load and the sliding velocity and contact areas from the worm gears driving conditions. The viscous friction generated in the worm gear was obtained with a theoretical approach and the result was applied to model the friction in the steering system. Finally, by viscous friction coefficient and Coulomb friction coefficient, values of friction in worm gear were calculated. According to the Bearing Company and the characteristics of each bearing, the friction torques due to load and due to speed were calculated. A MATLAB Simulink model for calculating the friction in bearings and worm gear in C-EPS were done and the total friction value was estimated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a href="https://publications.waset.org/abstracts/search?q=worm%20gear" title=" worm gear"> worm gear</a>, <a href="https://publications.waset.org/abstracts/search?q=column%20electric%20power%20steering%20system" title=" column electric power steering system"> column electric power steering system</a>, <a href="https://publications.waset.org/abstracts/search?q=simulink" title=" simulink"> simulink</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing" title=" bearing"> bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=EPS" title=" EPS"> EPS</a> </p> <a href="https://publications.waset.org/abstracts/58098/friction-calculation-and-simulation-of-column-electric-power-steering-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58098.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">358</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">87</span> Examining Customer Acceptance of Chatbots in B2B Customer Service: A Factorial Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kathrin%20Endres">Kathrin Endres</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Greven"> Daniela Greven</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although chatbots are a widely known and established communication instrument in B2C customer services, B2B industries still hesitate to implement chatbots due to the incertitude of customer acceptance. While many studies examine the chatbot acceptance of B2C consumers, few studies are focusing on the B2B sector, where the customer is represented by a buying center consisting of several stakeholders. This study investigates the challenges of chatbot acceptance in B2B industries compared to challenges of chatbot acceptance from current B2C literature by interviewing experts from German chatbot vendors. The results show many similarities between the customer requirements of B2B customers and B2C consumers. Still, due to several stakeholders involved in the buying center, the features of the chatbot users are more diverse but obfuscated at the same time. Using a factorial survey, this study further examines the customer acceptance of varying situations of B2B chatbot designs based on the chatbot variables transparency, fault tolerance, complexity of products, value of products, as well as transfer to live chat service employees. The findings show that all variables influence the propensity to use the chatbot. The results contribute to a better understanding of how firms in B2B industries can design chatbots to advance their customer service and enhance customer satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chatbots" title="chatbots">chatbots</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20acceptance" title=" technology acceptance"> technology acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=B2B%20customer%20service" title=" B2B customer service"> B2B customer service</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20satisfaction" title=" customer satisfaction"> customer satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/155894/examining-customer-acceptance-of-chatbots-in-b2b-customer-service-a-factorial-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155894.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">124</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">86</span> Association of Lipoprotein Lipase Gene (HindIII rs320) Polymorphisms with Moderate Hypertriglyceridemia Secondary to Metabolic Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meryem%20Abi-Ayad">Meryem Abi-Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Biagio%20Arcidiacono"> Biagio Arcidiacono</a>, <a href="https://publications.waset.org/abstracts/search?q=Eusebio%20Chiefari"> Eusebio Chiefari</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Foti"> Daniela Foti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Benyoucef"> Mohamed Benyoucef</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Brunetti"> Antonio Brunetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lipoprotein Lipase (LPL) is a key enzyme for lipid metabolism; its genetic polymorphism can be a candidate for modulating lipids parameters in metabolic syndrome. The objective of the present study was to determine whether lipoproteins lipase polymorphisMetS (LPL-HindIII) could be associated with moderate hypertriglyceridemia (secondary to metabolism syndrome). The polymorphism Hind III (rs320) was assessed by PCR-RFLP in 51 MetS patients and 17 healthy controls from the hospital in Tlemcen. The logistic regression analyses showed no significant association with Hind III genotype and hypertriglyceridemia (TG ≥ 1,5g/l or TG lower treatment) (P=0,455), metabolic syndrome (P=0,455), hypertension (P=0,802) and type 2 diabetes (P=0,144). In terms of plasma biomarkers, although not statistically significant, there was a difference in TG levels (P > 0,05), which was lowest among carriers of the homogenous mutant allele (H-). In this study, there was no association between the rare allele (H-) and disease protection, and between the frequent allele (H+) and disease prevalence (hypertriglyceridemia, metabolic syndrome, hypertension, type 2 diabetes). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moderate%20secondary%20hypertriglyceridemia" title="moderate secondary hypertriglyceridemia">moderate secondary hypertriglyceridemia</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndrome" title=" metabolic syndrome"> metabolic syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism%20lipoprotein%20lipase" title=" polymorphism lipoprotein lipase"> polymorphism lipoprotein lipase</a>, <a href="https://publications.waset.org/abstracts/search?q=HindIII%28rs320%29" title=" HindIII(rs320)"> HindIII(rs320)</a> </p> <a href="https://publications.waset.org/abstracts/73036/association-of-lipoprotein-lipase-gene-hindiii-rs320-polymorphisms-with-moderate-hypertriglyceridemia-secondary-to-metabolic-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73036.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">321</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">85</span> Analysis of Vocal Pathologies Through Subglottic Pressure Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Perla%20Elizabeth%20Jimarez%20Rocha">Perla Elizabeth Jimarez Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Daniela%20Tejeda%20Franco"> Carolina Daniela Tejeda Franco</a>, <a href="https://publications.waset.org/abstracts/search?q=Arturo%20Minor%20Mart%C3%ADnez"> Arturo Minor Martínez</a>, <a href="https://publications.waset.org/abstracts/search?q=Annel%20Gomez%20Coello"> Annel Gomez Coello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the biggest problems in developing new therapies for the management and treatment of voice disorders is the difficulty of objectively evaluating the results of each treatment. A system was proposed that captures and records voice signals, in addition to analyzing the vocal quality (fundamental frequency, zero crossings, energy, and amplitude spectrum), as well as the subglottic pressure (cm H2O) during the sustained phonation of the vowel / a /; a recording system is implemented, as well as an interactive system that records information on subglottic pressure. In Mexico City, a control group of 31 patients with phoniatric pathology is proposed; non-invasive tests were performed for these most common vocal pathologies (Nodules, Polyps, Irritative Laryngitis, Ventricular Dysphonia, Laryngeal Cancer, Dysphonia, and Dysphagia). The most common pathology was irritative laryngitis (32%), followed by vocal fold paralysis (unilateral and bilateral,19.4 %). We take into consideration men and women in the pathological groups due to the physiological difference. They were separated in gender by the difference in the morphology of the respiratory tract. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amplitude%20spectrum" title="amplitude spectrum">amplitude spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=fundamental%20frequency" title=" fundamental frequency"> fundamental frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=subglottic%20pressure" title=" subglottic pressure"> subglottic pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20crossings" title=" zero crossings"> zero crossings</a> </p> <a href="https://publications.waset.org/abstracts/149795/analysis-of-vocal-pathologies-through-subglottic-pressure-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149795.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">120</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">84</span> Evaluation of Corrosion in Steel Reinforced Concrete with Brick Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julieta%20Daniela%20Chelaru">Julieta Daniela Chelaru</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Gorea"> Maria Gorea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The massive demolition of old buildings in recent years has generated tons of waste, especially brick waste. Thus, a concern of recent research is the use of this waste for the production of environmentally friendly concrete. At the same time, corrosion in classical concrete is a current problem. In this context, in the present paper a study was carried out on the corrosion of metal reinforcement in cement mortars with brick waste. The corrosion process was analyzed on four compositions of mortars without and with 15 %, 25 % and 35 % bricks waste replacing the sand. The brick waste has a majority content in SiO2, Al₂O₃, FeO₃ and CaO. The grain size distribution of brick waste was close to that of the sand (dₘₐₓ = 3 mm). The preparation method of the samples was similar to ordinary mortars. The corrosion properties of concrete, at different waste bricks concentrations, on rebar, were investigated by electrochemical measurements (Tafel curves and EIS) at 1 and 6 months. The results obtained at 6 months revealed that the addition of the bricks waste in mortar are improved the anticorrosion properties, in the case of all samples compared with the sample with 0% bricks waste. The best results were obtained in the case of the sample with 15% bricks waste (the efficiency was ≈ 90 %). The corrosion intermediary layer formed on the rebar surface was determined by SEM-EDX. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EIS" title="EIS">EIS</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20corrosion" title=" steel corrosion"> steel corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20reinforced%20concrete" title=" steel reinforced concrete"> steel reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20materials" title=" waste materials"> waste materials</a> </p> <a href="https://publications.waset.org/abstracts/137552/evaluation-of-corrosion-in-steel-reinforced-concrete-with-brick-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137552.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">338</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">83</span> Promoting Teaching and Learning Structures Based on Innovation and Entrepreneurship in Valahia University of Targoviste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20Teodorescu">Gabriela Teodorescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioana%20Daniela%20Dulama"> Ioana Daniela Dulama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In an ever-changing society, the education system needs to constantly evolve to meet market demands. During its 30 years of existence, Valahia University of Targoviste (VUT) tried to offer its students a series of teaching-learning schemes that would prepare them for a remarkable career. In VUT, the achievement of performance through innovation can be analyzed by reference to several key indicators (i.e., university climate, university resources, and innovative methods applied to classes), but it is possible to differentiate between activities in the classic format: participate to courses; interactive seminars and tutorials; laboratories, workshops, project-based learning; entrepreneurial activities, through simulated enterprises; mentoring activities. Thus, VUT has implemented over time a series of schemes and projects based on innovation and entrepreneurship, and in this paper, some of them will be briefly presented. All these schemes were implemented by facilitating an effective dialog with students and the opportunity to listen to their views at all levels of the University and in all fields of study, as well as by developing a partnership with students to set out priority areas. VUT demonstrates innovation and entrepreneurial capacity through its new activities for higher education, which will attract more partnerships and projects dedicated to students. <p
