Tal avaliação torna-se ainda mais importante, quando se trata do tomate de indústria, uma das hortaliças de maior valor econômico no Brasil e que os fertilizantes chegam a representar 18 % do custo de produção. Para tanto, conceitos de interpretação à diagnose do estado nutricional foram desenvolvidos, como o Sistema Integrado de Diagnose e Recomendação (DRIS) e Diagnose da Composição Nutricional (CND), abordagem CND-clr (relação log centralizada) e CND-ilr (relação log isométrica). Com isso, o objetivo da realização do presente trabalho foi obter as normas e a faixa de suficiência, bem como comparar tais metodologias, a partir dos dados de nutrientes (N, P, K, Ca, Mg, S, B, Cu, Fe, Mg e Zn). Quando analisados individualmente, com exceção do método DRIS, os métodos CND-clr e CND-ilr, apresentaram boas performances e com bons parâmetros de calibração dos métodos. Contudo, quando analisados de maneira conjunta, segundo a distância de Mahalanobis e a partição de Cate-Nelson, todos os métodos, incluindo a transformação log neperiano do teor, não apresentaram diferença significativa. / The evaluation of nutritional status through leaf analysis is important, as a complement to soil chemical analysis, for the identification of nutritional imbalance and ancillary fertilizer recommendation. This evaluation becomes even more important when it comes to the tomato industry, one of the vegetables with the highest economic value in Brazil, and that fertilizers represent 18% of the cost of production. For this purpose, concepts of interpretation and diagnosis of nutritional status were developed, such as the Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND), CND-clr (centralized log ratio) and CND-ilr (isometric log rato) approach. Thus, the goal of the implementation of this work was to obtain standards and sufficiency range and compare these methods, from the nutrient data (N, P, K, Ca, Mg, S, B, Cu, Fe , Mn and Zn). When analyzed individually, with the exception of the DRIS, the CND-clr and CND-ilr methods presented good performances and with good calibration parameters of the methods. However, when analyzed together, according to the Mahalanobis distance and the Cate-Nelson partition, all methods, including log transformation of the content, showed no significant difference. / FAPESP: 2013/24447-4 / FAPESP: 2015/11321-8

Porovnání kvality života seniorů v institucionálním zařízení v časovém období dvou let / The comparison of quality seniors´ life in the institutional establishment in the period of time for two years

KORTUSOVÁ, Jana January 2007 (has links)
The topic of old age and ageing is wide-ranging. The position of senior citizens within a society and the solution of the questions connected with the consequences of their growing age represents an integral part of the natural life cycle. Apart from their material security the quality range of senior citizens{\crq} life is made up of their state of health, accessibility of both public and private health, social and other services, marital status, the quality of housing, the chance of further education and developing social contacts. The quality of life is a very subjective and individual phenomenon. It involves different impulses for various people in different periods. There is a general tendency towards rising demands on the quality of life within the population and it the same with the oncoming generation of senior citizens. It is always necessary to ask oneself a question whether the quality of senior citizens{\crq} lives in institutional facilities is on an appropriate level and which are the factors influencing the quality of their lives. Evaluating the quality of life can be also looked upon as a subjective individual{\crq}s view of the individual aspects of his life. However, it is highly important that the living environment meets and satisfies the senior citizens{\crq} corporal, psychic, social and spiritual needs. This diploma thesis represents a continuation of the bachelor{\crq}s thesis: The quality of senior citizens{\crq} life in institutional facilities. The basic aim is to compare the quality of senior citizens{\crq} life in the institutional facility {--} the Old People{\crq}s Home of Kůsov within a period of two years. I have chosen the topic of the thesis because I have been working in an institutional facility for more than 21 years, and the quality of senior citizens{\crq} life has made me think about this problem more thoroughly. The diploma thesis includes the present state of affairs of the problems in question, the specification of hypotheses, methodology, the results of the research, discussion, conclusion, the list of the sources, key words and supplements. The description of the present state of affairs comprises the characteristic features of the senior citizens{\crq} population, senior citizens{\crq} state of health, their self-sufficiency and activities. Another concept is the quality of life. Provided that we combine the word quality with that of life, we will face the fact that various people can have and usually do have different ideas about what in fact comprises the meaning of their life, what makes their life of high quality. The quality of life is looked upon as a multi-dimensional quantity and is usually defined as a ``subjective appraisal of one{\crq}s own conditions of life{\crqq}. Further on there are institutional facilities and the new Social Care Act No. 108/2006 digest mentioned in this part. There have two hypotheses been specified in this thesis, which have been confirmed by the research. The original research sample of the year 2004 included 100 respondents: 40 men and 60 women. Within the period of two years 22 respondents died, 8 men and 14 women. These respondents were taken away from the total sample and, as a result, a new representative sample has come into being comprising 78 respondents, 32 men ans 46 women. The research was carried out by means of the method of a controlled dialogue, using a questionnaire for the users of the old people{\crq}s home, the standardized SEIQoL questionnaire and an ADL test. The results were compiled in tabular and chart form, and subsequently processed by means of the STATISTICA statistical programme. The discussion includes a summary of the research knowledge in comparison with the sources used. The conclusion comprises a summary of the complete research part. We can conclude that nowadays the quality of life in an institutional facility can reach a high level.

Revmatoidní artritida versus Bechtěrevova choroba z hlediska závislosti na sociální síti / Rheumatoid arthritis versus ankylosing spondylitis from the view of dependence to social network

JELENOVÁ, Michaela January 2011 (has links)
The number of rheumatic diseases has been increasing in Europe. It is estimated that currently up to a quarter of Europeans suffer from some type of rheumatism. Rheumatoid arthritis and Bechterew's disease (ankylosing spondylitis) are chronic diseases manifested by pain, stiffness, inflammation of joints and the back. The theoretical section is divided into two parts; the first part defines rheumatoid arthritis and Bechterew's disease from the health point of view. The second part is devoted to the social area that is often neglected. The aim of the practical section of the thesis is to reveal how rheumatoid arthritis differs from Bechterew's disease in terms of the use of social assistance, as well as employability or participation in social life. For the data collection, qualitative research methods and interviewing techniques were used. The addressed respondents were patients of rheumatology consulting rooms of the Medipont Plus Ltd., who were divided into two groups ? patients with rheumatoid arthritis and those with Bechterew's disease. The research has shown that persons suffering form rheumatoid arthritis are more likely to get a disability pension than those with Bechterew's disease and they also more often use social contributions, most frequently the extra benefits for people with disabilities ? ZTP cards. This is related to a lower work capability in patients with rheumatoid arthritis compared to those with Bechterew's disease. The research results are influenced by the age of the respondents, the length of the illness, the difference in the roles of men and women and last but not least, by personality characteristics. The research has proved that patients suffering from rheumatic diseases as well as those suffering from Bechterew's disease and undergoing biological treatment are more self-sufficient due to this modern treatment. It has also been found that the respondents who are not fully self-sufficient are not informed about the possibilities to get social benefits and contributions and do not know where to get this information. The thesis could provide an impetus for the strategy when rheumatic diseases are not considered only a medical issue, because these diseases significantly influence the lives of the people affected and thus become a serious psychosocial issue.

The objective of this study was to establish norms in areas of conventional and transgenic soybean in southeastern counties of the state of Goiás to create a database that will allow the use of DRIS in the region. In addition, to diagnose most of the nutritional limiting factors for the obtainment of high yields in soybeans by leaf analysis, performed by the methods of Concentration Ranges and DRIS. Areas of commercial soybeans were selected in the counties of Silvânia, Vianópolis and Luziania, GO, Brazil. In these areas, 103 sampling plots of conventional and 260 plots of transgenic soybeans were demarcated. In each plot, 10 leaves were collected, removing the third expanded trifoliate with the petiole from the tip of the main stem, at the beginning of the flowering stage to form a composite sample. After physiological maturity, production samples were collected taking a meter of plants in the rows, in five randomly selected points in each plot. Foliar analyzes were interpreted by the methods of Concentration Ranges and DRIS. Norms for conventional and transgenic soybean were established from a reference population with yield higher than 3,500 kg ha-1 of soybeans to calculate DRIS indices. The methods of diagnosis used in this work had in common the nutrient N as the most limiting factor for conventional and transgenic soybeans. Nutrients N, Cu and Zn were considered the most limiting factors for the two types of soybeans by the Method of Concentration Ranges. The DRIS method diagnosed nutrients N and P as the most limiting factors for the two types of soybeans and showed higher sensitivity for diagnosing nutritional problems, especially for micronutrients. / O Sistema Integrado de Diagnose e Recomendação (DRIS) tem mostrado-se eficiente como método para diagnóstico nutricional das culturas. O presente trabalho teve como objetivo obter normas em áreas de produção comercial de soja convencional e transgênica em municípios da região Sudeste do Estado de Goiás para criar um banco de dados que permitirá a utilização do DRIS na região. E ainda, diagnosticar os fatores nutricionais mais limitantes à obtenção de altas produtividades para a cultura da soja através de análise foliar, interpretada pelos métodos das Faixas de Concentração e DRIS. Foram selecionadas áreas de produção comercial de soja nos municípios de Silvânia, Vianópolis e Luziânia, GO. Nessas áreas foram demarcadas 103 glebas de amostragem de soja convencional e 260 glebas de soja transgênica. Em cada gleba, coletou-se 10 folhas de soja, retirando-se o terceiro trifólio expandido com pecíolo, a partir da ponta da haste principal, no início do florescimento para compor uma amostra composta. Posteriormente, após a maturação fisiológica, foram colhidas amostras da produção, tomando um metro linear de plantas nas linhas de plantio, em cinco pontos escolhidos aleatoriamente em cada gleba de soja. As análises foliares foram interpretadas pelos métodos das Faixas de Concentração e DRIS. Foram estabelecidas normas para soja convencional e soja transgênica a partir de uma população referência com produtividade maior que 3.500 kg ha-1 de grãos de soja para cálculo dos índices DRIS. Os métodos de diagnose avaliados neste trabalho apresentaram em comum, o nutriente N, como mais limitante para soja convencional e transgênica. Os nutrientes N, Cu e Zn foram considerados os mais limitantes para os dois tipos de soja pelo método das Faixas de Concentração. O método DRIS diagnosticou os nutrientes N e P como os mais limitantes para os dois tipo de soja e ainda apresentou maior sensibilidade para diagnosticar problemas nutricionais, especialmente, para micronutrientes

Recuperação do potássio adicionado em solos com diferentes teores e o efeito na disponibilidade às plantas / Recovery of added potassium in soils with different levels and the effect on availability to plants

Dierings, Wagner Capitanio 30 May 2012 (has links)
The sustainability of production is widespread and discussed within the productive systems, resource utilization of the productive chain of the agricultural sector, mainly inputs, requires constant evaluations, since their socio-economic and environmental impacts may be irreversible. Potassium is the second nutrient requirement in terms of the cultures, in countries such as Brazil becomes evident, the growing demand for this element, however, more than 90% of the raw material for the manufacture of potash fertilizers is imported. Because to the large variability of existing soils, and different physicochemical properties of the minerals fertilizers in relation with the environment, parameters for fertilizer recommendations are based on physical and chemical properties of the soil, and sufficiency levels, within which it is possible to quantify and qualify the ability to release soil nutrients for plants. Several experiments with potassium, agronomically significant response is observed only at doses similar to the amounts exported by crops. This Work aims to improve and maximize the utilization of potassium added, so that will include technical and economic aspects, productivity and ensure a satisfactory integrated restricting the indiscriminate use of potash fertilizers, thus confirm or discard the following hypotheses. 1) Is added potassium recovered plants so, the fixing of this element into soil does not at significant levels. 2) Addition of K2O doses of higher levels existing in the soil increase the availability of potassium for plants stimulating the absorption enough above the limits for a given production. 3) The critical levels indicated as basis for recommendation are unnecessary; the addition of potassium can be based only on the need for certain crop yields. The study consisted of two experiments, so first occurred in the field, with two successive crops of soybean and wheat, on a Typic Hapludalf (EMBRAPA, 2006), located next to the department of soils, Federal University of Santa Maria (Universidade Federal de Santa Maria UFSM), in Santa Maria, RS, Brazil, with a history of potassium fertilization from 1991, the second were held in a greenhouse, and was based, soil samples collected in the area of the first experiment, and samples of an Typic Oxisol (EMBRAPA, 2006), coming from the Embrapa/Soy (Embrapa/soja) Londrina, PR, Brazil, also with a history of potassium fertilization from 1983. In both experiments the experimental units vary, as the initial content of potassium in the soil, and the amount of K2O added. / A sustentabilidade da produção é amplamente difundida e discutida dentro dos sistemas produtivos, a utilização dos recursos da cadeia produtiva do setor agrícola, principalmente insumos, necessita de avaliações constantes, uma vez que seus impactos sócio-econômicos e ambientais podem ser irreversíveis. O potássio é o segundo nutriente em termos de exigência pelas culturas, em países como o Brasil torna se evidente, a crescente demanda desse elemento, porém, mais de 90% da matéria prima para a fabricação de fertilizantes potássicos é importada. Devido à grande variabilidade de solos existentes, e às diferentes propriedades físico-químicas dos minerais fertilizantes em relação ao meio, os parâmetros para recomendação de fertilizantes baseiam-se em propriedades físicas e químicas do solo, e níveis de suficiência, dentro dos quais é possível quantificar e qualificar a capacidade de liberação de nutrientes do solo para as plantas. Vários experimentos com potássio têm observado resposta agronomicamente significativa apenas nas doses similares a quantidade exportada pelas culturas. O presente trabalho tem como objetivo melhorar e maximizar o aproveitamento do potássio adicionado, de maneira que venha a contemplar aspectos técnicos e econômicos, e garantir uma produtividade satisfatória integrada à restrição do uso indiscriminado de fertilizantes potássicos, desta forma, comprovar ou descartar as seguintes hipóteses: 1) O potássio adicionado é recuperado pelas plantas de tal forma, a fixação deste elemento pelo solo não ocorre em níveis significativos. 2) A adição de doses de K2O sobre teores mais elevados já existentes no solo aumenta a disponibilidade de potássio para as plantas, estimulando a absorção acima dos limites suficientes para determinada produção. 3) Os níveis críticos apontados como base para recomendação são desnecessários, e a adição de potássio pode se basear apenas na necessidade das culturas para determinadas produtividades. O trabalho constituiu-se de dois experimentos. O primeiro ocorreu no campo, com dois cultivos sucessivos de soja e trigo, sobre um Argissolo Vermelho distrófico típico (EMBRAPA 2006), localizado junto ao departamento de solos da Universidade Federal de Santa Maria, Santa Maria, RS, Brasil, com histórico de fertilização potássica a partir de 1991, e o segundo transcorreu em casa de vegetação, e teve como base, amostras de solos coletadas na área do primeiro experimento, e amostras de um Latossolo Vermelho distrófico típico (EMBRAPA, 2006) oriundo da Embrapa/Soja Londrina, PR, Brasil, também com histórico de adubação potássica, desde 1983. Em ambos os experimentos as unidades experimentais variam, quanto ao teor inicial de potássio no solo, e a quantidade de K2O adicionada.

Nitrate-nitrogen sufficiency ranges in leaf petiole sap of pac choi grown with organic and conventional fertilizers

Elfar Altamimi, May January 1900 (has links)
Master of Science / Department of Horticulture, Forestry, and Recreation Resources / Rhonda R. Janke / Petiole sap nitrate-nitrogen (NO3-N) analysis with handheld meters is a valuable tool in applying in-season nitrogen (N) for many crops. Sufficiency levels have been determined for several leafy green crops, including lettuce (Lactuca sativa L.) and cabbage (Brassica oleracea L.), but not for pac choi (Brassica rapa L.). The response of pac choi to different fertilizer rates and sources [conventional and organic] has established optimal soluble N application rates and Cardy meter sufficiency ranges. Greenhouse experiments were conducted during summer and fall of 2008 in Manhattan, KS. Conventional soluble fertilizer was formulated from inorganic salts with a 4 NO3-N: 1 ammonium ratio. Phosphorus was held at 1.72mM and K at 0.83mM for all treatment levels. The organic soluble fertilizer, fish hydrolyzate (2N:1.72P:0.83K), was diluted to provide the same N levels as with conventional treatments. Both fertilizers were applied at rates of 0, 32, 75, 150, 225, 300, and 450 mg. L-1. Seedlings were transplanted and fertilizer application began at 18 days. Plants were harvested at seven weeks (five weeks post transplanting) after receiving 15 fertilizer applications during production. Samples of the most recently matured leaves were harvested weekly and analyzed for petiole sap NO3-N and leaf blade total N concentration. Leaf count, leaf length, and chlorophyll content were also measured weekly. Fresh and dry weights were determined on whole shoots and roots. Optimum yield was achieved at the 150 mg. L-1 fertility rate with both conventional and organic fertilizers. Field and high tunnel experiments were conducted during fall 2008 to validate the sufficiency ranges obtained from the greenhouse studies. Based on field and high tunnel results, sufficiency levels of NO3-N for pac choi petiole sap during weeks 2 to 3 of production were 800-1500 mg. L-1, and then dropped to 600-1000 mg. L-1 during weeks 4 through harvest for both conventional and organic fertilizers sources. These ranges could vary based on the variety of the crop, the fertility of soil, and certain environmental factors such as photoperiod, light intensity. However, we found that petiole sap nitrate always increased to the point associated with the maximum biomass, followed by a plateau where sap nitrate remained constant. This characteristic of the Cardy meter can provide the growers with a practical methodology to generate their standard curves under specific conditions to guide in-season N applications. Total N in leaf tissue showed fewer fertilizer rate effects than petiole sap NO3-N. Chlorophyll content was not useful in evaluating pac choi N status.

Diagramas de influência e teoria estatística / Influence Diagrams and Statistical Theory

Rafael Bassi Stern 09 January 2009 (has links)
O objetivo principal deste trabalho foi analisar o controverso conceito de informação em estatística. Para tal, primeiramente foi estudado o conceito de informação dado por Basu. A seguir, a análise foi dividida em três partes: informação nos dados, informação no experimento e diagramas de influência. Nas duas primeiras etapas, sempre se tentou definir propriedades que uma função de informação deveria satisfazer para se enquadrar ao conceito. Na primeira etapa, foi estudado como o princípio da verossimilhança é uma classe de equivalência decorrente de acreditar que experimentos triviais não trazem informação. Também foram apresentadas métricas que satisfazem o princípio da verossimilhança e estas foram usadas para avaliar um exemplo intuitivo. Na segunda etapa, passamos para o problema da informação de um experimento. Foi apresentada a relação da suficiência de Blackwell com experimentos triviais e o conceito usual de suficiência. Também foi analisada a equivalência de Blackwell e a sua relação com o Princípio da Verossimilhança anteriormente estudado. Além disso, as métricas apresentadas para medir a informação de conjuntos de dados foram adaptadas para também medir a informação de um experimento. Finalmente, observou-se que nas etapas anteriores uma série de simetrias mostraram-se como elementos essenciais do conceito de informação. Para ganhar intuição sobre elas, estas foram reescritas através da ferramenta gráfica dos diagramas de influência. Assim, definições como suficiência, suficiência de Blackwell, suficiência mínima e completude foram reapresentadas apenas usando essa ferramenta. / The main objective of this work is to analyze the controversial concept of information in Statistics. To do so, firstly the concept of information according to Basu is presented. Next, the analysis is divided in three parts: information in a data set, information in an experiment and influence diagrams. In the first two parts, we always tried to define properties an information function should satisfy in order to be in accordance to the concept of Basu. In the first part, it was studied how the likelihood principle is an equivalence class which follows from believing that trivial experiments do not bring information. Metrics which satisfy the likelihood principle were also presented and used to analyze an intuitive example. In the second part, the problem became that of determining information of a particular experiment. The relation between Blackwell\'s suciency, trivial experiments and classical suciency was presented. Blackwell\'s equivalence was also analyzed and its relationship with the Likelihood Principle was exposed. The metrics presented to evaluate the information in a data set were also adapted to do so with experiments. Finally, in the first parts a number of symmetries were shown as essencial elements of the concept of information. To gain more intuition about these elements, we tried to rewrite them using the graphic tool of influence diagrams. Therefore, definitions as sufficiency, Blackwell\'s sufficiency, minimal sufficiency and completeness were shown again, only using influence diagrams.

Autossuficiência energética de queimador de biogás instalado em miniestação de tratamento de efluentes

Dalmacio Almeida 28 June 2014 (has links)
Este trabalho apresenta os estudos técnicos para implantação de um sistema de geração de energia que atenda a demanda dos circuitos eletroeletrônicos de um queimador de biogás, tornando-o autossuficiente energeticamente e viabilizando sua instalação em locais distantes e não atendidos pelo sistema convencional de distribuição de energia. O projeto do sistema de geração de energia tem como base a associação das tecnologias fotovoltaica e termoelétrica direta, tipo efeito Seebeck. O queimador de biogás descrito neste projeto é instalado em miniestações de tratamento de efluentes com produção de biogás, onde o aproveitamento energético da forma tradicional é inviável em função da baixa e inconstante vazão de biogás. O queimador de biogás possui um circuito eletrônico de controle que determina o tempo de combustão do biogás, onde, através de um microcontrolador, recebe informações do circuito eletrônico de controle e registra o volume de biogás queimado, objetivando a obtenção dos créditos de carbono. O queimador de biogás tem como objetivo somente o saneamento, provocando a queima do gás metano (CH4) presente no biogás e permitindo a busca por créditos de carbono, contribuindo para a diminuição dos efeitos provocados pelos gases do efeito estufa (GEE). Durante os estudos, foi constatado que a energia gerada pelo painel fotovoltaico é suficiente para atender a demanda de energia do circuito eletroeletrônico do queimador de biogás, enquanto que o sistema termoelétrico direto obteve resultados desprezíveis. Constatou-se também que parte do circuito do controlador de carga, utilizado nesse estudo, pode futuramente ser inserida no firmware do microcontrolador já existente no projeto, reduzindo assim significativamente os componentes do circuito. / This paper presents the technical studies for the implementation of a system of power generation to meet the energy demand of biogas burner electronics circuits, making it self-sufficient energy and enabling installation in remote locations not served by the conventional system of energy distribution. The design of the power generation system is based on the combination of photovoltaic technologies and thermoelectric direct like Seebeck Effect. The biogas burner described in this project is installed in mini-stations for treatment and biogas production, where energy reuse in the traditional way is not feasible due to the low and variable flow of biogas. The biogas burner has an electronic control circuit which determines the time of combustion of biogas, which, through a microcontroller receives information from the electronic control circuit and registers the volume of biogas flared aiming to get carbon credits. The biogas burner, aims only sanitation, causing burning methane gas (CH4) present in biogas and allowing the search for carbon credits, helping to reduce the effects caused by greenhouse gases (GHG). During the studies, it was found that the energy generated by the photovoltaic panel is enough to attend the energy demand of the electronics circuit of biogas burner, while the direct thermoelectric system obtained a negligible result. It was found that part of the charge controller, used in this study, in the future can be inserted into the firmware of the microcontroller existing of the in the project, reducing therefore the circuit components significantly.
