abstract: To increase the deployment of photovoltaic (PV) systems, a higher level of performance for PV modules should be sought. Soiling, or dust accumulation on the PV modules, is one of the conditions that negatively affect the performance of the PV modules by reducing the light incident onto the surface of the PV module. This thesis presents two studies that focus on investigating the soiling effect on the performance of the PV modules installed in Metro Phoenix area. The first study was conducted to investigate the optimum cleaning frequency for cleaning PV modules installed in Mesa, AZ. By monitoring the soiling loss of PV modules mounted on a mock rooftop at ASU-PRL, a detailed soiling modeling was obtained. Same setup was also used for other soiling-related investigations like studying the effect of soiling density on angle of incidence (AOI) dependence, the climatological relevance (CR) to soiling, and spatial variation of the soiling loss. During the first dry season (May to June), the daily soiling rate was found as -0.061% for 20o tilted modules. Based on the obtained soiling rate, cleaning PV modules, when the soiling is just due to dust on 20o tilted residential arrays, was found economically not justifiable. The second study focuses on evaluating the soiling loss in different locations of Metro Phoenix area of Arizona. The main goal behind the second study was to validate the daily soiling rate obtained from the mock rooftop setup in the first part of this thesis. By collaborating with local solar panel cleaning companies, soiling data for six residential systems in 5 different cities in and around Phoenix was collected, processed, and analyzed. The range of daily soiling rate in the Phoenix area was found as -0.057% to -0.085% for 13-28o tilted arrays. The soiling rate found in the first part of the thesis (-0.061%) for 20o tilted array, was validated since it falls within the range obtained from the second part of the thesis. / Dissertation/Thesis / Masters Thesis Engineering 2014

abstract: This is a two-part thesis: Part 1 characterizes soiling losses using various techniques to understand the effect of soiling on photovoltaic modules. The higher the angle of incidence (AOI), the lower will be the photovoltaic (PV) module performance. Our research group has already reported the AOI investigation for cleaned modules of five different technologies with air/glass interface. However, the modules that are installed in the field would invariably develop a soil layer with varying thickness depending on the site condition, rainfall and tilt angle. The soiled module will have the air/soil/glass interface rather than air/glass interface. This study investigates the AOI variations on soiled modules of five different PV technologies. It is demonstrated that AOI effect is inversely proportional to the soil density. In other words, the power or current loss between clean and soiled modules would be much higher at a higher AOI than at a lower AOI leading to excessive energy production loss of soiled modules on cloudy days, early morning hours and late afternoon hours. Similarly, the spectral influence of soil on the performance of the module was investigated through reflectance and transmittance measurements. It was observed that the reflectance and transmittances losses vary linearly with soil density variation and the 600-700 nm band was identified as an ideal band for soil density measurements. Part 2 of this thesis performs statistical risk analysis for a power plant through FMECA (Failure Mode, Effect, and Criticality Analysis) based on non-destructive field techniques and count data of the failure modes. Risk Priority Number is used for the grading guideline for criticality analysis. The analysis was done on a 19-year-old power plant in cold-dry climate to identify the most dominant failure and degradation modes. In addition, a comparison study was done on the current power plant (framed) along with another 18-year-old (frameless) from the same climate zone to understand the failure modes for cold-dry climatic condition. / Dissertation/Thesis / Masters Thesis Engineering 2015

abstract: Using a simple $SI$ infection model, I uncover the overall dynamics of the system and how they depend on the incidence function. I consider both an epidemic and endemic perspective of the model, but in both cases, three classes of incidence functions are identified. In the epidemic form, power incidences, where the infective portion $I^p$ has $p\in(0,1)$, cause unconditional host extinction, homogeneous incidences have host extinction for certain parameter constellations and host survival for others, and upper density-dependent incidences never cause host extinction. The case of non-extinction in upper density-dependent incidences extends to the case where a latent period is included. Using data from experiments with rhanavirus and salamanders, maximum likelihood estimates are applied to the data. With these estimates, I generate the corrected Akaike information criteria, which reward a low likelihood and punish the use of more parameters. This generates the Akaike weight, which is used to fit parameters to the data, and determine which incidence functions fit the data the best. From an endemic perspective, I observe that power incidences cause initial condition dependent host extinction for some parameter constellations and global stability for others, homogeneous incidences have host extinction for certain parameter constellations and host survival for others, and upper density-dependent incidences never cause host extinction. The dynamics when the incidence function is homogeneous are deeply explored. I expand the endemic considerations in the homogeneous case by adding a predator into the model. Using persistence theory, I show the conditions for the persistence of each of the predator, prey, and parasite species. Potential dynamics of the system include parasite mediated persistence of the predator, survival of the ecosystem at high initial predator levels and ecosystem collapse at low initial predator levels, persistence of all three species, and much more. / Dissertation/Thesis / Doctoral Dissertation Mathematics 2017

INTRODUÇÃO: o câncer de estômago já foi, mundialmente, a neoplasia com maior ocorrência na população. Ao longo das décadas, a incidência deste câncer apresenta tendência de decréscimo significativo, sendo que, atualmente, é o quinto tumor maligno mais frequente no mundo. A mortalidade não acompanhou a tendência de decréscimo na mesma velocidade e ainda é considerada a terceira principal causa de morte por câncer. O Brasil acompanhou a tendência mundial, registrando o declínio significativo da incidência e da mortalidade. O município de São Paulo apresenta as mais altas taxas de incidência e mortalidade do país. Apesar disso, existem poucos estudos de tendências de incidência dessa neoplasia para São Paulo e este é o primeiro estudo que investiga as tendências de incidência e mortalidade por sexo, por faixas etárias e por tipo histológico. OBJETIVO: analisar as tendências dos coeficientes de incidência e mortalidade do câncer de estômago, segundo sexo, faixa etária e tipo histológico pela classificação de Lauren. MÉTODOS: estudo ecológico de séries temporais. Foram analisados os novos casos de câncer de estômago, diagnosticados no período de 1997 a 2011, no município de São Paulo, cadastrados no Registro de Câncer de Base Populacional de São Paulo, e os óbitos por câncer de estômago do período de 1980 a 2011, de residentes no Município de São Paulo, obtidos do site do Departamento de Informática do Sistema Único de Saúde (DATASUS) do Ministério da Saúde. Foram feitas análises de séries temporais por sexo, faixa etária e tipo histológico utilizando a classificação de Lauren. Os coeficientes brutos e padronizados foram calculados e utilizados nas análises de tendências, através dos modelos de regressão linear e do cálculo da mudança percentual anual (APC). RESULTADOS: foram analisados 24.512 casos incidentes e 31.215 óbitos. Houve redução da incidência (APC -8,3 por cento em homens e -6,5 por cento em mulheres) e da mortalidade (APC -2,3 por cento em homens e -2,5 por cento em mulheres). Houve tendência de queda em todas as faixas etárias, com exceção da faixa etária mais jovem (20-29 anos), que apresentou estabilidade da incidência e da mortalidade. A estabilidade na faixa etária mais jovem também foi identificada nos tipos intestinal e difuso. O tipo difuso apresentou estabilidade também nas faixas etárias: 30-39, 40-49 e 80 anos do sexo feminino. CONCLUSÃO: São Paulo acompanhou a tendência mundial de decréscimo na incidência e na mortalidade, entretanto, a mesma tendência não foi observada entre adultos jovens, principalmente a faixa etária de 20 a 29 anos. Atenção especial deve ser dada ao tipo difuso, que não apresentou queda na tendência de incidência do câncer de estômago para as mulheres de 20 a 49 anos. / INTRODUCTION: the stomach cancer was once considered as the most incident neoplasm worldwide. Over the decades, the stomach cancer incidence has been showing a significant decreasing trend, and is currently the fifth most common malignancy in the world. Mortality has not followed this decreasing trend at the same speed and is still considered the third leading cause of cancer death. Brazil follows this global trend, having a significant decline both in incidence and mortality. Across the regions of Brazil, the city of São Paulo has one of the highest incidence and mortality rates. Nevertheless, there are few studies on trends of this neoplasm in Sao Paulo and this is the first study to investigate the trends of incidence and mortality by sex, age group and histological type. OBJECTIVE: to analyze the trends in stomach cancer incidence and mortality, according to gender, age group and histological type of Lauren\'s classification. METHODS: this is an ecological time-series study. We analyzed the new cases of stomach cancer diagnosed between 1997 and 2011 in São Paulo registered in the Population Based Cancer Registry of São Paulo and deaths from stomach cancer from 1980 to 2011, in the city of São Paulo, obtained from the Ministry of Health website - Department of the Unified Health System (DATASUS). Time series analyzes were performed by gender, age group and histological type using the Lauren classification of intestinal-type and diffuse type. Crude and agestandardized rates were calculated and used in time trend analysis, through linear regression models and the annual percentage change (APC). RESULTS: we analyzed 24,512 incident cases and 31,215 deaths. There was a reduction in the incidence (APC -8.3 per cent men and -6.5 per cent women) and mortality (APC -2.3 per cent men and 2.5 per cent women). A decreasing trend was observed for all age groups, except for the youngest (20-29 years) for which stability was observed. Both intestinal and diffuse types remained stable in the youngest age group. The diffuse type was stable also in the age groups: 30-39, 40-49 and 80 years female. CONCLUSION: São Paulo followed the global trend of decrease in incidence and mortality, however, the same trend was not observed among young adults, especially the age group 20-29 years. Special attention should be given to diffuse type that showed no reduction in the incidence trend of stomach cancer for women 20-49 years female.

No segundo foram utilizados 48 leitões, num delineamento em blocos com arranjo fatorial 2 x 2 x 2 x 3 (duas classes de pesos ao desmame x duas fontes de carboidratos x duas porções do intestino delgado x três épocas de abate). Portanto, no modelo estatístico foram usados os efeitos fixos de peso, fontes de carboidratos, porções do intestino delgado, épocas de abate e suas respectivas interações; e o efeito aleatório de blocos. O objetivo deste estudo foi avaliar os efeitos da substituição da lactose pela maltodextrina nas rações de leitões desmamados, com diferentes pesos, sobre o consumo diário de ração, ganho diário de peso, conversão alimentar, incidência de diarreia, altura das vilosidades, profundidade das criptas e espessura de mucosa. No primeiro experimento, nos períodos de 0 a 17 e 0 a 29 dias após o desmame constatou-se efeito da classe de peso, no ganho diário de peso e no consumo diário de ração dos leitões, ou seja, os animais mais pesados ao desmame apresentaram maiores consumo diário de ração e ganho diário de peso em relação aos animais mais leves. No segundo experimento, verificou-se que a maltodextrina determinou aumentos na espessura média da mucosa intestinal dos leitões, independente do peso, e na profundidade média das criptas apenas nos animais leves. A maltodextrina pode ser usada como uma alternativa para substituir a lactose nas rações de leitões desmamados, pois não afeta negativamente o desempenho e a maioria dos parâmetros morfométricos do intestino. / Two trials were conducted: in the first trial, were used, 96 weaning pigs at the age of about 21 days, in a 2 × 2 factorial arrangement (two sources of carbohydrate: lactose and maltodextrin and two weaning weight classes: light, from 4,50 to 5,20 kg, and heavy, from 5,90 to 6,60 kg). In the second trial, 48 pigs, in a 2 x 2 x 2 x 3 factorial arrangement (two weaning weight classes x two sources of carbohydrate x two portions of the small intestine x three slaughter times). Therefore, in the statistical model the fixed effect of weight, sources of carbohydrate, portions of the small intestine, times of slaughter and its respective interactions; and the random effect of blocks. The objective of this study was to evaluate the effects of maltodextrin diets in weaning pigs of different weights on feed intake, feed:gain ratio, weight gain, diarrhea incidence, villus height, crypt depth and mucous membrane height. In the first trial, from 0-17 days and from 0-29 days after the weaning effects of weight classes, were detected on daily weight gain, and daily feed intake. The heaviest animals at weaning showed the best results. In the second trial, we verified that maltodextrin determined an increase in the average thickness of the intestinal mucosa, regardless of weight classes, and the increase in the average depth of the crypt, only in the highter animals. Maltodextrin can be used as an alternative to lactose in diets of weaning pigs, as it doesn’t affect negatively the performance neither the morfometric parameters of the intestine.

This research was carried out to evaluate the effects of treatments with phosphorylated mannanoligosacharides, bioflavonoids, bioflavonoids+phosphite, potassium phosphite and salicylic acid on Penicillium spp. rot occurrence and on maturity, ripening and quality of Fuji&#8223; apples. The evaluated variables were incidence and severity of Penicillium spp. rot, flesh firmness, texture attributes, soluble solids content, titratable acidity, peel color, starch-iodine index, respiration rate and ethylene production. The experiments followed a randomized block design at preharvest, and a completely randomized design at postharvest, with four replicates. The means were compared by Tukey&#8223;s test (p<0.05). Inducers of resistance applied at preharvest do not control the incidence of Penicillium spp. rot in Fuji&#8223; apples. However, potassium phosphite at the dose of 3 mL L-1, applied 5 days before the fruit harvest, delays the development of rot caused by Penicillium spp. in apples kept at ambient temperature. The postharvest treatments with potassium phosphite reduce the incidence and severity by Penicillium spp. rot in Fuji&#8223; apples. The treatment with inducers of resistance does not affect fruit maturity and ripening, as well as does not significantly interfere on quality attributes of Fuji&#8223; apples / Um dos principais problemas na pós-colheita de maçãs é a podridão causada por Penicillium spp., a qual causa muitas perdas qualitativas e quantitativas no setor frutícola. O trabalho teve o objetivo de avaliar o efeito das substâncias mananoligossacarídeo fosforilado, bioflavonóides, bioflavonóides mais fosfito, fosfito de potássio e ácido salicílico sobre a ocorrência de podridão por Penicillium spp. e sobre a maturação, amadurecimento e qualidade de maçãs Fuji&#8223;. As variáveis analisadas foram incidência e severidade de danos pela podridão de Penicillium spp., firmeza de polpa, atributos de textura, sólidos solúveis, acidez titulável, cor da epiderme, índice iodo-amido, taxa respiratória e produção de etileno. Utilizou-se delineamento em blocos ao acaso nos experimentos em pré-colheita e inteiramente casualizado nos experimentos em pós-colheita, com quatro repetições. As médias foram comparadas pelo teste de Tukey (p<0,05). A aplicação pré-colheita de indutores de resistência não controla a incidência de podridões por Penicillium spp. em maçãs Fuji&#8223;. Todavia, o fosfito de potássio na dose de 3 mL L-1, aplicado 5 dias antes da colheita, retarda o desenvolvimento das podridões em maçãs Fuji&#8223; mantidas em temperatura ambiente. O uso pós-colheita de fosfito de potássio diminui a incidência e severidade de podridões por Penicillium spp. em maçãs Fuji&#8223;. O uso de indutores de resistência não influencia a maturação e o amadurecimento de maçãs Fuji&#8223;, bem como não interfere significativamente nos atributos de qualidade dos frutos

A presente dissertação trata do estudo da situação das águas, a partir de uma análise genérica de sua disponibilidade quantitativa e qualitativa no planeta, assim como do seu comprometimento para a satisfação das necessidades humanas, dentro do modelo de sociedade hoje experimentado. O propósito é verificar a viabilidade da utilização da característica da extrafiscalidade tributária, mormente no que diz respeito ao campo de incidência do Imposto Sobre a Propriedade Predial e Territorial Urbana, como instrumento eficiente para contribuir para seu melhor e mais racional aproveitamento. Nesse contexto, a defasagem dos recursos hídricos é aqui mirada através do prisma do modelo social calcado no hiperconsumo, que fomenta políticas econômicas cegadas pela constante necessidade de crescimento e que causam um ataque desenfreado aos recursos naturais do orbe. Assim, a água e os demais bens naturais são vilipendiados pela promoção de sua utilização dentro de um modelo de consumo autofágico, que ignora o fato de que sua origem não emana de fonte cornucopiana. Na trilha proposta pela pesquisa, a análise da perspectiva da mercantilização da água, mormente pela privatização dos serviços que não garantem seu acesso aos cidadãos, demonstrou seu distanciamento da condição de bem comum da humanidade, porquanto legada sua disponibilidade àqueles com capacidade econômica para custear os preços estabelecidos pelo mercado. Por fim, a adoção de mecanismos inerentes à extrafiscalidade tributária, objeto de crescente número de propostas legislativas voltadas à criação de incentivos fiscais aos administrados que aderem a condutas que melhoram o aproveitamento e racionalizam a utilização dos recursos hídricos, apresenta-se como uma alternativa capaz de alcançar grandes êxitos. / Submitted by Ana Guimarães Pereira (agpereir@ucs.br) on 2017-06-20T16:40:06Z No. of bitstreams: 1 Dissertacao Paulo Roberto Polesso.pdf: 1000871 bytes, checksum: b5fad1b0f24ee5d182c5679f704b817f (MD5) / Made available in DSpace on 2017-06-20T16:40:06Z (GMT).

The objective is to verify the feasibility of the use of extrataxation, mainly in terms of the Urban Real Estate Tax, as an efficient instrument to contribute to its better and more rational use. In this context, the degradation of the water resources is studied here from the point of view of the social model, based on the hyperconsumerism, which promotes economic policies blinded by the increasing necessity of growth and causes an uncontrolled attack to the planet natural resources. In this way, water and other natural assets are vilified due to the promotion of their use inside of a model of self-destructive consumption, which ignores the fact that it does not come from a cornucopia. In this way, the analysis of the perspective of water mercantilization, mainly because of the privatization of the services which assure the citizens access to it, proved its distance from the condition of humanity common asset, since it is available to the ones who can afford the prices established by the market. Finally, the adoption of mechanisms inherited to the extrataxation, object of an increasing number of regulations proposals in terms of creating tax incentives to the ones who adhere to actions which enhance and rationalize the use of the water resources, are an alternative capable of reaching excellent results.
