Companies have always been organized by processes, often imperceptible to its employees. With the advancement of technology, organizational processes currently run an organization through computers, and thus generate immediate information that is available to each sector. With the objective of seeking business information in real time, the government created the SPED - Public System of Digital, which involves three subsystems, which are the Electronic Invoice, Digital Accounting Bookkeeping and Digital Tax Bookkeeping. This system is revolutionizing the business structures when gathering, in an innovative way, all information and interlinked business processes. For the implementation of SPED, a revision in the organizational processes is required, since the information is generated and is sent online to the government, without mistakes. Thus the study aimed to analyze the change brought about by the implementation of the Public System of Digital SPED in the main business processes. In order to do so, we have performed a multiple case study involving three companies in the state of Para, two operate in wholesale and one explores agribusiness. The Data collection was performed by accounting professionals, IT and managers. According to the results obtained, it was found that in two companies, the IT infrastructure was capable of deploying the new system without major problems, while one company had more difficulties to cope with the new system. However, all companies had to examine its processes to make the customizations needed to fit. It was also observed that there is no IT Governance in two companies. Therefore, we recommend the use of an appropriate model, not only for the implementation of SPED, but as a way to manage and extract better results from investment in information technology

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation

The measurement of patient satisfaction can provide information about the success of the care provider in reaching the values and meeting the expectations of the patient. The purpose of this study was to translate into the Portuguese language and to culturally customize to the Brazilian population the instrument to measure patient satisfaction with physical therapy elaborated by Goldstein et al. The study sample was made up of 279 patients who were undergoing physical therapy treatment at 39 different private clinics in a middle-sized town in northeastern Brazil. For the translation of the survey instrument, the back-translation technique was employed, in association with the bilingual method. The reliability and validity of the Brazilian version of the instrument were both assessed. Reliability analysis, carried out with the computation of Cronbach alpha coefficients, showed that the measures obtained with the instrument have a high degree of internal consistency. The aspects dealing with the patient therapist relationship are the most important predictors of satisfaction, followed by those dealing with courtesy, privacy, and practical aspects such as efficiency of the facility in the patient admissions process, setting up of appointments, and waiting time in waiting room. Items dealing with aspects such as location of the facility and availability of parking facilities may underestimate the reliability of the instrument. This study translated, culturally customized, and validated an instrument to measure patient satisfaction with physical therapy originally developed in English. By so doing, this study has made this instrument available to the Brazilian society, and it has rendered it a useful parameter that can be utilized in our country in the field of physical therapy

Para testar o efeito da temperatura e do tempo de embebição nos valores de condutividade elétrica e verificar sua aplicabilidade para determinar a qualidade fisiológica de sementes de Dalbergia nigra (jacarandá-da-bahia), foram utilizadas sementes colhidos em três anos (lote I _ 1998; lote II _ 1997 e lote III - 1994). Inicialmente determinou-se o teor de água e depois conduziu-se os testes de germinação em laboratório e viveiro, utilizando-se quatro repetições de 25 sementes. Para estudar a condutividade elétrica (CE) foram utilizadas quatro repetições de 50 sementes. Cada subamostra foi colocada em recipiente contendo 75ml de água deionizada, embebidas por 6, 12, 18, 24, 30 e 36 horas, a 20, 25 e 30ºC. Sementes do lote II apresentaram maiores valores na primeira contagem da germinação, diferindo significativamente dos demais lotes. O lote III apresentou qualidade inferior. Com o aumento do período e da temperatura de embebição ocorreu aumento nos valores de CE das sementes dos três lotes. O lote III mostrou qualidade fisiológica inferior a dos lotes I e II, que apresentaram valores mais elevados de CE. Não houve diferenciação entre os lotes I e II. Concluiu-se que o teste de CE foi eficiente para diferenciar os lotes de sementes de Dalbergia nigra, com alto grau de associação com o teste de germinação.

Hylocereus undatus (Haw.), popularmente conhecida como pitaia vermelha é uma cactácea para a qual se tem registrado um aumento de consumo nos últimos anos e, por ser ainda pouco explorada, vários aspectos referentes à sua propagação ainda são desconhecidos. Até o momento, não existem critérios para a execução de testes de germinação para sementes dessa espécie, publicados nas Regras para Análise de Sementes. Nesse sentido, objetivou-se com este trabalho adequar a metodologia quanto ao substrato, temperatura e tempo de contagem inicial e final para o teste de germinação. Foram testados quatro substratos (rolo de papel, areia, vermiculita e solo) e quatro temperaturas (20, 25, 30 e 20-30°C). O efeito dos substratos no desempenho germinativo das sementes foi avaliado pelo teste de germinação e de primeira contagem instalado com quatro subamostras de 50 sementes. Foram feitas contagens diárias do número de plântulas emergidas até atingirem a estabilidade e, no final do experimento, foram avaliados a porcentagem de germinação das sementes, considerando as plântulas normais, anormais e sementes mortas. Concluiu-se que o teste de germinação de sementes de pitaia vermelha deve ser realizado à temperatura constante de 25°C em rolo de papel, com contagens inicial e final aos cinco e dez dias após a semeadura, respectivamente.

A eficiência dos testes de vigor na avaliação da qualidade de sementes, depende da sua padronização para as diferentes espécies. Neste contexto, os objetivos deste trabalho foram elaborar as curvas de absorção de água para determinar o período necessário ao ajuste do teor de água das sementes e aprimorar o teste de deterioração controlada para sementes de brócolis. Foram utilizadas sementes de três variedades: dois lotes de Piracicaba precoce, dois lotes de Flórida e quatro lotes de Ramoso. Os lotes foram caracterizados mediante a determinação do teor de água e germinação; o vigor foi determinado pelos testes de primeira contagem, comprimento de plântula, emergência e índice de velocidade de emergência. Foram determinadas as curvas de absorção de água por 84 horas. Para averiguar a eficiência do teste de deterioração controlada para sementes de brócolis, foi feito o ajuste do conteúdo de água das sementes para: 18, 20, 21, 23 e 24%, sendo estas expostas a 45ºC em banho-maria, por 24 horas. O delineamento utilizado foi o inteiramente casualizado. As médias foram comparadas pelo teste de Tukey a 5% de probabilidade. As curvas de absorção permitiram estimar os períodos de 15, 20, 22, 32 e 48 horas para elevação do teor de água a 18, 20, 21, 23 e 24% respectivamente. O teste de deterioração controlada, para sementes de brócolis, propiciou resultados promissores, tendo sido eficiente na separação de lotes, em todos os teores de água estudados, tanto quanto os testes de emergência de plântula e índice de velocidade de emergência.

A qualidade da semente na produção agrícola é um dos principais fatores a ser considerado na implantação da cultura, de forma que se torna importante a obtenção de informações sobre a germinação e o vigor das sementes, além da necessidade de avaliá-los. Dentro desse contexto, este trabalho teve como objetivo adequar a metodologia do teste de condutividade elétrica para a avaliação da qualidade fisiológica de sementes de Pisum sativum subsp. arvense. Para tanto, foram utilizados dez lotes de sementes da cultivar IAPAR 83, empregando-se períodos de condicionamento de 8, 16, 20, 24 e 28 horas, combinados às temperaturas de 20 e 25°C e volumes de 75 e 250mL de água. Além destes, foram conduzidos os testes de germinação, primeira contagem de germinação e emergência de plântulas. Para ambas as avaliações, foram utilizadas quatro repetições de 50 sementes. Os testes de vigor, assim como o teste de germinação foram sensíveis para avaliar a qualidade das sementes dos diferentes lotes estudados, porém houve variações na ordenação deles quanto ao vigor. O volume de água, o tempo e a temperatura de embebição influenciaram os valores de condutividade elétrica. Concluiu-se que o teste de condutividade elétrica utilizando 250mL de água, na temperatura de 25°C por 24 horas é promissor para a diferenciação de lotes de sementes de P. sativum subsp. arvense.

This study aimed to establish the adequate concentrations of nitrapyrin for the effective inhibition of oxygen demand required for the oxidation of nitrogen compounds during aerobic mineralization of leachate. The aquatic macrophyte Myriophyllum aquaticum was used as a source of dissolved organic matter (DOM). The leachate was incubated in several chambers, containing different composition and treatments: (i) treatment with leachate (DOM), (ii) treatment with DOM plus nitrapyrin in different concentrations (10; 25 and 50 mg L-1), aiming at finding the right concentration that inhibits the nitrification process, (iii) treatment with DOM plus NH4SO 2, (iv) treatment containing DOM and nitrapyrin plus NH 4SO2, and (v) treatment with DOM plus azide. The dissolved oxygen amount in each incubation treatment was periodically measured. The results indicated that the ratio of 10 mg L-1 of nitrapyrin for each 10 mg C of leachate is efficient in inhibiting the oxidation of nitrogen compounds from aquatic macrophytes.

In São Paulo state, deforestation and agriculture activities are increasing soil losses processes, especially in areas of susceptible soils where soil conservation practices are not adopted. Environmental adequacy at property level regarding Permanent Protection Areas and Legal Reserves is considered a potential factor for reducing soil losses and it was based on this fact that we assessed soil losses of different scenarios of environmental adequacy. Simulations of erosive processes were carried out in 15 catchments of the Corumbataí river basin, with different forest restoration scenarios, as well as the current situation of land use/ land cover. The scenarios include reforestation of Permanent Preservation Areas (PPA); the reforestation hydrological sensitive areas; and two scenarios, the Legal Reserve installation in 20% of each catchment, being one of them for most critical areas in terms of erosion and the other at random. It was observed that the establishment of PPA and the reforestation of hydrological sensitive areas (HSA), offered a small contribution to the control of the erosive process, resulting in a reduction of 10% and 7.4%, respectively, while the legal reserve in critical areas has the significant reduction of 69.8%. The random scenario, in turn, resulted in a reduction of 21.4% of erosion. Results show that reforestation can reduce soil losses, but previous studies of land prioritization and planning could significantly increase its efficiency.
