Ministerio de Educación, Ciencia y Tecnología Universidad Tecnológica Nacional Facultad Regional Reconquista 2011-Año del Trabajo Decente, la Salud y Seguridad de los Trabajadores PROYECTOS DE INVESTIGACIÓN VIGENTES - RESÚMENES CURRENT RESEARCH PROJECTS - ABSTRACTS Facultad Regional Reconquista Universidad Tecnológica Nacional ENERGY OPTIMIZATION IN THE EDIBLE OIL INDUSTRY AT RECONQUISTA CITY Contact: Prof. Dr. O. Iribarren Email: [email protected] The research plan consists of three stages. The first was a thermal audit of the oil plants aimed at the generation of opportunities for improvement in thermal integration. The second, currently ongoing, is a specific study about alternative choices for a fuel to feed the boilers. The region lacks natural gas, and wood, the traditional fuel used by the local industry, is becoming more expensive as it is harvested each time farther. We will study the convenience of either gasify a lignocellulosic waste generated by a nearby cotton processing factory, or use it as a solid fuel after pelleting, through a both economic and environmental impact assessment. The third line is more comprehensive and will take the information generated in previous phases to address a global analysis considering also other alternatives of use of locally generated biomass residues. Not only as solid or liquid fuels as they are employed now, but also for the production of liquid biofuels ethanol - diesel, biogas, or after recovering some valuable components e.g. tocopherols or lecithin, developing a methodology to simultaneously address the material and energy integration of processes in the agro-industrial chain in the area of Reconquista, which includes the oil and sugar chains and the production of biodiesel and bioethanol in the neighborhood of Reconquista. The methodology can be briefly described as a “Source-Sink” programming, using process models as optional “Operators” to convert Sources into alternative Sources, acceptable by alternative Sinks e.g. the market in case of valuable products, as raw materials of the existing processes, or again as fuels. A first advance in this line has been published as “Synthesis of a Mass Integrated Biodiesel Process” Carlos Fischer and Oscar Iribarren Ind. Eng. Chem.

Contact: Ing. A. Morzán Email: [email protected] This work investigates and develops a method for electric energy generation, making use of a river flow. It also aims at avoiding big infrastructures such as the ones required by a hydroelectric dam. Although there are many turbines available in the market for small scale energy generation, none of them can operate efficiently within rivers of flat areas such as the ones found in middle Paraná region. For that reason, we are designing a turbine prototype that could be implemented within rivers of flat areas. This Project is motivated by the implementation of renewable energy to be applied in the northern of Santa Fe province of Argentina. The low cost and simplicity of the construction will make this device to be accessible for users of scarce economical resources. Besides, it will supply non-contaminant and cheap electric energy to geographical regions that are nowadays unprovided with conventional electricity. This project is carried out by advanced students and researchers of UTN - Facultad Regional Reconquista. MEASUREMENTS ON LOW VOLTAGE SUPPLY NETWORKS AND DETERMINATION OF HARMONIC DISTORTION Contact: Ing. D. Salinas Email: [email protected] Actually, international standards regarding electrical energy quality and pollution into the electric supply network with harmonic currents have gained special interest due to disturbances of the voltage waveform that is provided by the net. Ideally, this voltage waveform should be a pure sine wave with constant frequency, however, it does not happen because the voltage PARQUE INDUSTRIAL RECONQUISTA – TE 03482-420048 3560 – RECONQUISTA – SANTA FE Ministerio de Educación, Ciencia y Tecnología Universidad Tecnológica Nacional Facultad Regional Reconquista 2011-Año del Trabajo Decente, la Salud y Seguridad de los Trabajadores wave have perturbations such as noise in differential mode, electric pulses, fast or slow variations, voltage flicker, harmonic distortion and frequency variations. If the electric supply network would be free of users, it would have a good quality voltage wave, occasionally disturbed by faults in the generation centre, in the distribution or due to environmental factors. However, when a large number of users are connected to the network, it is subjected to a bid load of electric charges that can constantly alter the wave. Besides it can induce abnormal consumption or shorts, which can affect other loads that are closely connected. Therefore, analyzing and identifying the source of pollution and the effects of harmonics on low voltage distribution networks that supplies residential and commercial sectors, will help to mitigate the negative impact. It can be done by analyzing and interpreting current regulations, comparing measurement methods as well as instruments and results. This work studies the harmonic content, which is represented by the Total Harmonic Distortion (THD), and the deterioration of the power factor in the low voltage networks. Measurements are carried out in Reconquista and Avellaneda cities of Santa Fe province. Consequently, we expect to obtain crucial information to determine the harmonic distortion and provide a mitigation plan and/or solution in order to improve energy quality in this region. IMPACT OF SOFTWARE IMPLEMENTATION IN MATHEMATICS LEARNING Contact: Mg. Ing. H. Martín Email: [email protected] Different technologies have been developed though the history and mathematics has not been the exception. This how we went from abacus to manual adding machines to continue with the calculator and arrive at present with computers. This work investigates the use of computers as a tool for learning mathematics. In fact, there is a current rethinking of the methodology for teaching mathematics, modifying the relationship pupil-teacher-technological resources, to achieve a synergistic interaction that achieves high levels of understanding of the academic contents.

What kind of change can be observed with respect to mathematical skills? What kind of changes can be detected regarding the use of mathematical concepts? How Mathematica software helps in the learning process? In this project we analyze these questions for the particular case of students of engineering of the Facultad Regional Reconquista. STUDY OF LIGNOCELULOSES AND EXTRACTIBLES ON SURFACES FOR THE DEVELOPMENT OF NANO-STRUCTURES AND MOLECULAR MACHINES Contact: Dr. S. M. Mendoza Email: [email protected] Nanotechnology refers to a field whose theme is the control of matter on an atomic and molecular scale. Generally, nanotechnology deals with structures that are 100 nanometers or smaller, and involves developing materials or devices within that size. Materials reduced to the nanoscale can show different properties compared to what they exhibit on a macro-scale, enabling unique applications. For instance, opaque substances become transparent; stable materials turn combustible; solids turn into liquids at room temperature; insulators become conductors. Thus, nanotechnology has the potential to create many new materials and devices with wide-ranging applications, such as in medicine, electronics, energy production, and raw material saving. Lignocellulose and its extractible possess interesting properties for the fabrication of nanostructures and building blocks of molecular machines. However, they have not been deeply explored as nanomaterials. Thus, this project propose to study lignoceluloses of regional sources and its extractibles in order to investigate their potential as nanomaterial, in particular those molecules of interest for developing nanostructures and molecular machines. Particularly, we will study the surface of lignocelulosic samples modified by both etherification with epoxides and UV radiation. We will also study extractible on surfaces of Au(111) and PARQUE INDUSTRIAL RECONQUISTA – TE 03482-420048 3560 – RECONQUISTA – SANTA FE Ministerio de Educación, Ciencia y Tecnología Universidad Tecnológica Nacional Facultad Regional Reconquista 2011-Año del Trabajo Decente, la Salud y Seguridad de los Trabajadores HOPG. Samples will be characterized by XPS and STM. Moreover, we will explore techniques of low environmental impact to separate lignocellulose and extractible from they source. Therefore, we will advance in understanding matter at nano-scale, we will learn about the electronic structure, changes under several stimuli (chemical modification, UV radiation) and we will know about surface and interphase phenomena that have not been yet investigated. Besides scientific research, this project aim at establishing the basis of a new working line in the Facultad Regional Reconquista of Universidad Tecnológica Nacional. ANALYTICAL AND NUMERICAL SYSTEMATIZATION FOR FRAMEWORKS RESOLUTION: STATIC, DYNAMIC AND STRUCTURAL STABILITY, IN THE CONTEXT OF AEROSPACE, MECHANICAL AND CIVIL ENGINEERING. Contact: Mg. Ing. H. Martín Email: [email protected] This work is motivated by finding solutions to plane frameworks of closed systems, by developing power series. This development takes into account automaticity in the geometrical conditions of continuity and equilibrium for the case of characteristic forces at nodes, where two or more bars can access. Among engineering disciplines using bar frameworks – for both plane and spatial behaviours rigidity programs are used since decades. These programs select kinematic unknowns at the bar boundaries that change directions, simplifying the problem resolution of several bars connected in a node. The entire calculation programme is carried out by Software Mathematica 8. PARQUE INDUSTRIAL RECONQUISTA – TE 03482-420048 3560 – RECONQUISTA – SANTA FE
