The present investigation proposes: to design a tourist product in La Moya Beach, parish Guasuntos, canton Alausí, county of Chimborazo; with the purpose of transforming to the rural territory into a place of distraction and family recreation, guaranteeing to energize the local economy of the community and the parish Guasuntos through the generation of employments. Within the commercial viability it was determined the likes and preferences of the national and international tourists, from whic...
The aim of the study was to determine the cumulative absorbed dose in blood to the patients with Differentiated Thyroid Cancer (DTC) requiring Iodine 131 ( xvii 131 I) as a therapeutic modality, in the Hospital of Specialties "Teodoro Maldonado Carbo "(HTMC) IESS - Guayaquil September - March 2018. To do this, a dosimeter application software was designed using the Medical Internal Radiation Dose (MIRD) formalism, calculating the accumulated absorbed dose in blood per unit of trac...
This research was about the study of Graphene nanoribbon plasmonic character from 3p, 3p+1, and 3p+2 group, it was researched with the Time-dependent density functional theory (TD DFT) and the random phase approximation (RPA). This character was simulated due to the incidence of a radiation beam with energy under 20 eV with a momentum which under 3.252 x 10 -3 Bohr -1 was simulated in two conditions. Intrinsic, which analyzed the effect caused by the increase of temperature from 3...
This present investigation objective is to estimate the Entrance Surface Dose received by patients who have had interventional procedures as coronary angiography, Catheterization, and Percutaneous Coronary Intervention at Carlos Andrade Marín Hospital in Quito from September 2017 to January 2018. We used thermoluminescence dosimeters provided and analyzed by the Dosimetry Department. They were located on the posterior chest cavity region inside of the radiation field. The patients sel...
The objective of the present work of investigation was to develop a fusion tool of medical images SPECT/CT and an application of internal dosimetry to measure the absorbed doses in patients of the Carlos Andrade Marin Hospital (HCAM). In doing so it was elaborated a graphical interface (GUIDE) in MATLAB the algorithms of implemented fusion were: Simple fusion of images (Simple Average, Maximum Value, Minimum Value, Principal Component Analysis), Fusion based in the Pyramidal Decompositio...
This investigation aimed at elaborating a manual of procedures performed in the areas of the skull, thorax and abdomen for the Tomograph TOSHIBA ACTIVION in the Provincial General Scholastic Hospital Riobamba. It was started by preparing a manual of operating procedures and the implementation of quality control and radiological protection test within the tomography room. This manual was prepared based on different references from national and international institution and organization, m...
The objective of this degree work was to design and implement a quality control protocol to the Xray equipment in the area of Imaging from Hospital General Provincial Docente Riobamba. Therefore, the physical principle of the equipment's operation was described, as well as its mechanical and electrical composition detailing the functional capacity, production and use restrictions. The characterization of the protocol was obtained based on the deductive method with which the tests were ...
The objective was to implement a I-131 assessment method incorporated to the Occupationally Exposed Personnel (POE) of the Nuclear Medicine Department of the Carlos Andrade Marín Hospital, by means of the internal dosimetry with the H3000WW INFINIA HAWKEYE GP3 Gammacámara. The Gammacámara was characterized with tests of quality controls obtaining its calibration factor with the thyroid neck phantom, the calibration for each detector was performed in efficiency, the geometry of the stretc...
The objective of this research work was to design, build and implement a detection and monitoring system of ionizing radiation for the Nuclear Techniques Laboratory, due to there is currently no a system that allows us to maintain a personnel radiation dose register for the application of radiological protection. The state of the laboratory was evaluated in the design of the System, considering its facilities, equipment and instruments as well as the radioactive sources. There are two el...
In the present research, environmental noise levels were evaluated in seven fields of study in the urban area of the city of Riobamba. To monitor the environmental noise, an observational analysis of the city was carried out, finding 21 points to be monitored. Depending on the planimetry of the city of Riobamba, land use and occupation with its respective coordinates was classified in each point; afterwards, it was chosen a method and a measurement equipment that fulfil the regulation im...
The main purpose of this study was to conduct a quantum-mechanical study of the electronic and structural properties of the interaction of radon (222Rn) with graphene. The calculations were based on the functional density theory (DFT), using the local density approximation (LDA), generalized gradient approximation (GGA) and a hybrid functional (vdW-GGA). The radon/ graphene interaction was analyzed in three conformational sites: C (center of a hexagon), T (on a carbon atom), and B (on a ...
A radon detection method has been established in water from the natural slopes of the Carihuairazo volcano, in order to estimate the concentration of radon activity (222Rn). The transfer rate of 222Rn at the water air interface was experimentally determined and the effective dose of life rate at ingestion and inhalation of 222Rn present in the water is calculated. The method used consisted monitoring the growth of activity concentration of the radon inside the closed chamber, by means of...
The objective of this research was the construction of a prototype environmental radiation detector using plastic scintillators, which coupled a plastic scintillator of dimensions 25x25x1cm, a Silicon photomultiplier (SiPM) and a data acquisition system (DAQ-FPGA). The device was placed inside a dark box that isolated it from outside light in contact with the radioactive source (241Am, 90Sr, and 137Cs) and was tested for one and two scintillator blades. The acquisition and analysis of th...
The aim of the research work was to determine the dosimetry with the anthropomorphic phantom for the diagnosis of head and neck tumors in the Nuclear Medicine Unit of the Carlos Andrade Marín Hospital. For this study, a procedure was developed for the determination of the absorbed dose in target organs with Tc99m in the head and neck, for this purpose an anthropomorphic phantom was used that was acquired from the Departament of Control and Nuclear Applications (SCAN), where it is conside...
The objective of this research was to measure the quality of the institutional service, through the perception of the satisfaction of the students de la Escuela Superior Politécnica de Chimborazo, in the period October 2017- March 2018. For the information gathering, they applied questionnaire surveys structured in 7 blocks of questions, which represented the latent variables under study. Each question within the block represents a variable of measurement, counting finally with 33 variab...
Poverty is a worldwide very important issue for it is one of the main phenomena that is still unsolved to society. On this research the aim was to calculate an index of poverty, which has been called INPO, through the use of Structural Equation Models (SEM). This model shows the relationship between the variables in study. For it is a novel methodology which has been relatively unexplored in areas of economy, the importance of applying it, is highlighted. SEM involve 4 variables: Housi...
The purpose of the following research is to desing a Quality of Management Sistem for Instituto de Posgrado y Educacion Continua of Escuela Superior Politecnica de Chimborazo under ISO 9002:2008norm during of period 2015, this was carried out in order to improve the processes to meet the customers´ exigencies througt the accomplishment of the requirements established. A previous planning over the design of the research was carried out in a qualitative way using the inductive method, surveys, ...
The objetive of this research was to desing and build an Index of Basic Unmet Needs, weighing the basic needs as essential for the population such as: housing, overcrowding, basic services, education and income. Through the methodology of basic unmet needs, an index was desiged and by the Principal Components Analysis a Weighted Basic Unmet Neds Index was constructed, for which the data generated in the National Survey of Incomes and Expenditures of Urban and Rural Ecuadorian Households ...
