Gingivitis en niños con malnutrición por exceso y diabetes mellitus, hospital El Pino, San Bernardo

Tesis (Cirujano Dentista)Objetivo: El presente estudio tiene por finalidad determinar si existe una relación entre la gingivitis y la malnutrición por exceso asociada a alteraciones en el metabolismo de la glucosa en pacientes pediátricos atendidos en el policlínico de obesidad del Hospital y CRS El Pino en la comuna de San Bernardo, Chile. Metodología: Se obtuvieron los datos personales como la edad, género, índice de masa corporal (IMC) y comorbilidades desde las fichas clínicas del servicio de pediatría. Posteriormente se realizaron exámenes clínicos intraorales a 60 niños, dentro de los cuales 55 de ellos estaban diagnosticados como obesos y los restantes con condición de sobrepeso. En relación a la glicemia, 32 de ellos padecían de resistencia a la insulina o diabetes mellitus, el resto fueron pacientes del grupo control sin alteraciones en el metabolismo de la glucosa. Para evaluar la salud periodontal se utilizó una sonda periodontal OMS. Se midió el Índice gingival de Löe y Silness para determinar el grado de inflamación realizando una exploración con sonda en seis dientes por paciente. Se utilizaron pastillas reveladoras de placa bacteriana para determinar el Índice de higiene O’Leary lo que nos indicó la cantidad de biofilm dental de cada paciente. Resultados: Se observó una presencia de inflamación gingival similar entre los grupos al igual que el porcentaje de higiene oral. Conclusiones: No existe una diferencia significativa en relación a la presencia de gingivitis en pacientes obesos con alteración en el metabolismo de la glucosa versus el grupo control.Objective: This study aims to determine whether there is a link between gum disease and overweight was associated with alterations in glucose metabolism in pediatric patients treated at the polyclinic of obesity and CRS El Pino Hospital in the town of San Bernardo, Chile.

Computer Aided Analysis of Periodically Switched Linear Networks

Interest in analysing periodically switched linear networks has developed in response to the rapid development of sampled data communications systems. In particular, integrated circuit switched capacitor networks play an important part in modern analogue signal processing systems. This thesis addresses the problem of developing techniques for analysing periodically switched linear networks in the time and frequency domains that are suited to computer implementation and therefore facilitate the development of efficient computer aided analysis tools for these networks. Systems of large sparse complex linear equations arise in many network analysis problems and efficient techniques for solving these systems are crucial to the analysis methods developed in this thesis. By extending the concept of sparsity to include the type of the nonzero elements, very efficient solution and optimal ordering algorithms are developed. A new method for computing the time domain response of linear networks is presented. The method is based on numerical inversion of the Laplace transform and polynomial approximation of the excitations. This high accuracy method is well suited to solving large stiff systems and is extremely efficient. The method is extended to periodically switched linear networks and provides the basis for frequency domain analysis. A new frequency domain analysis method is presented that is orders of magnitude faster than existing techniques. This efficiency is achieved by developing a formulation such that AC analysis is not required, which allows the system to be solved as a discrete system. A special system compression reduces the solution of this discrete system to the solution of the network in one phase only. This solution step, which ordinarily requires O(N3) operations, is made more efficient by reducing the system to upper Hessenberg form in a preprocessing step, which then reduces the solution cost to O(N2) operations

An assessment of the implication of involving local communities in biodiversity conservation : a case study of Blouberg Nature Reserve in Limpopo, South Africa

Thesis (M.Sc. (Geography)) -- University of Limpopo, 2020This work aimed at assessing the implications of involving local communities in biodiversity conservation in Blouberg Nature Reserve (BNR) in Limpopo Province, South Africa. To achieve this objective, firstly biodiversity status before and after involving local communities in conservation initiatives was assessed using multi-temporal medium-resolution Landsat series data and species diversity indices. The results showed that there were significant variations (α = 0.05) in tree species diversity in BNR for before and after involving local communities. For example, tree species diversity was low after involving communities particularly for the years 1996 and 2019. Secondly, benefits and costs of involving local communities in biodiversity conservation as well as their investigate views, perceptions and attitudes BNR management were assessed. The study demonstrated local communities do not obtain sufficient benefits or incur numerous costs from the nature reserve. Despite this, there was considerable support for biodiversity conservation (84.2%) since household respondents still held positive attitudes towards biodiversity conservation in the reserve. For, example most of them indicated that they would report illegal activities to the authorities. However, despite lack of participation by the majority of the household respondents (89.6%) in biodiversity conservation, they demonstrated understanding of the relevance of nature conservation. In contrary, the BNR Manager stated that the local communities received benefits in the form of fuel-wood for special occasions such as funerals and bush meat sold at treasury approved tariffs during culling. However, illegal activities like poaching are still experienced in the nature reserve. Thus, the study underscores the relevance the integrating satellite data and qualitative information in assessing the ecological condition of PAs. Such information can help in biodiversity monitoring and decision-making on conservation of biodiversity. Keywords: biodiversity conservation; community-based natural resource management approach; ecological status; mapping; satellite data; spatial characterisation; species diversity; statistical analysis

KARAKTERISASI KECEPATAN PUTARAN BERDASARKAN RASIO INPUT BAHAN BAKAR PADA GENERATOR SET DUAL FUEL (GASOLINE – BIOGAS) MENGGUNAKAN JARINGAN SYARAF TIRUAN

Currently, energy consumption in Indonesia has increased so that the utilization of renewable energy is more developed to supply projections for future energy needs. One of the renewable energy sources that is being developed is biogas, especially for household-scale biogas. There are several types of biogas implementation at the household scale, one of which is the use of biogas as generator fuel to produce electricity. Fuel generators can use biogas in full or mix gasoline with biogas fuel. Electric generator sets with dual gasoline-biogas fuel can save the use of gasoline as fuel and can also increase the performance of generators. The gasoline-biogas mixture ratio affects engine performance, one of which is the rotational speed. However, at present the ratio of gasoline to biogas is still manually regulated on household scale biogas usage. Based on these conditions, the artificial neural networks(ANN) method was developed in this study which aims to find the optimal ratio in order to get the generator set rotational speed characterization with the best engine performance value. A total of 300 variations of data were processed using 75% for training with the number of hidden nodes 100 net.trainParam.goal value = 0.0001, net.trainParam.lr = 0.01, and net.trainParam.epochs = 1000, and 25% for the test. This study produced a RMSE training value of 10.4812 at node 55 and a test RMSE value of 5.8301 with a rotational speed of 3445.87, and obtained the best ratio of 0.012 L / min gasoline and 5 L / min biogas
