    Parchment stands for a multifaceted material made from animal skin, which has been used for centuries as a writing support or as bookbinding. Due to the historic value of objects made of parchment, understanding their degradation and their condition is of utmost importance to archives, libraries and museums, i.e., the assessment of parchment degradation is mandatory, although it is hard to do with traditional methodologies and tools for problem solving. Hence, in this work we will focus on the development of a hybrid decision support system, in terms of its knowledge representation and reasoning procedures, under a formal framework based on Logic Programming, complemented with an approach to computing centered on Artificial Neural Networks, to evaluate Parchment Degradation and the respective Degree-of-Confidence that one has on such a happening.(undefined

    Mobile transaction management in mobisnap

    Lecture Notes in Computer Science, 1884To allow mobile users to continue their work while disconnected, mobile systems usually rely on optimistic replication techniques. In mobile database systems, mobile units cache subsets of the database state and allow disconnected users to perform transactions concurrently. These transactions are later integrated in the master database state. As concurrently performed transactions may conflict, it is usually impossible to determine the result of an update in the mobile unit. Moreover, this model differs from the traditional client/server model due to the fundamental fact that the user will usually not be connected to the system when the results of his transactions are finally determined - therefore, he can not immediately perform adequate alternative actions. In this paper we describe a transaction management system that takes into consideration the above-mentioned characteristics. Transactions are specified as mobile transactional programs, which allows the precise definition of operation semantics and the definition of alternative actions. Support for active user notification is also provided in the system. Finally, the system relies on a reservation mechanism to be able to guarantee the results of transactions in the mobile units.(undefined

    OBJECTIVE: The majority of cases of hepatocellular carcinoma have been reported in individuals with cirrhosis due to chronic viral hepatitis and alcoholism, but recently, the prevalence has become increasingly related to nonalcoholic steatohepatitis around the world. The study aimed to evaluate the clinical and histophatological characteristics of hepatocellular carcinoma in Brazilians' patients with nonalcoholic steatohepatitis at the present time. METHODS: Members of the Brazilian Society of Hepatology were invited to complete a survey regarding patients with hepatocellular carcinoma related to nonalcoholic steatohepatitis. Patients with a history of alcohol intake (>;20 g/day) and other liver diseases were excluded. Hepatocellular carcinoma diagnosis was performed by liver biopsy or imaging methods according to the American Association for the Study of Liver Diseases’ 2011 guidelines. RESULTS: The survey included 110 patients with a diagnosis of hepatocellular carcinoma and nonalcoholic fatty liver disease from nine hepatology units in six Brazilian states (Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Rio Grande do Sul). The mean age was 67±11 years old, and 65.5% were male. Obesity was observed in 52.7% of the cases; diabetes, in 73.6%; dyslipidemia, in 41.0%; arterial hypertension, in 60%; and metabolic syndrome, in 57.2%. Steatohepatitis without fibrosis was observed in 3.8% of cases; steatohepatitis with fibrosis (grades 1-3), in 27%; and cirrhosis, in 61.5%. Histological diagnosis of hepatocellular carcinoma was performed in 47.2% of the patients, with hepatocellular carcinoma without cirrhosis accounting for 7.7%. In total, 58 patients with cirrhosis had their diagnosis by ultrasound confirmed by computed tomography or magnetic resonance imaging. Of these, 55% had 1 nodule; 17%, 2 nodules; and 28%, ≥3 nodules. CONCLUSIONS: Nonalcoholic steatohepatitis is a relevant risk factor associated with hepatocellular carcinoma in patients with and without cirrhosis in Brazil. In this survey, hepatocellular carcinoma was observed in elevated numbers of patients with steatohepatitis without cirrhosis

    The methods of land evaluation are intended to guide the appropriate land use, as the development of specialized algorithms propose to be less subjective assessments based on quantitative data. The aim was to evaluate the use of an expert system based on interpretation of soil properties and landscape features with that obtained by a control group, consisting of six experts. Samples of soil was collected by borehole profiles uses in IX Brazilian Meeting of Soil Classification and Correlation in order to get the data entered the program, and appraisers used the physical, chemical and morphological data of soil profiles. The expert system has shown promise in assessing the suitability for Latossolos, Argissolos, Vertissolos and Luvissolos, however still requires revisions to certain rules of interpretation for a more consistent fitness especially for Espodossolos. However, the assessment of experts did not identify the potential for land use in Amazon.Keywords: environmental services; land use; farm planning.Os métodos de avaliação da aptidão agrícola tem como objetivo orientar o uso adequado das terras, porém seus resultados apresentam elevado grau de subjetividade devido a serem dependentes da experiência do usuário. Neste trabalho objetivou-se avaliar o uso de um algoritmo para interpretação de propriedades do solo e características da paisagem e compará-lo com a interpretação obtida por um grupo controle, constituído por seis especialistas. Foram utilizadas amostras de solo coletadas por tradagem ao lado dos perfis pedológicos da IX Reunião Brasileira de Correlação e Classificação de Solos, de modo a obter os dados de entrada do algoritmo, enquanto os avaliadores utilizaram os dados físicos, químicos e morfológicos dos perfis pedológicos. A avaliação do grupo controle não identificou as potencialidades para o uso dos solos na Amazônia de forma consistente, enquanto, o algoritmo mostrou-se promissor na avaliação da aptidão para Latossolo, Argissolos, Vertissolos e Luvissolo, no entanto, ainda requer revisões em algumas regras de interpretação para uma avaliação mais coerente da aptidão, principalmente, para o Espodossolo.Palavras-chave: serviços ambientais, uso da terra, planejamento agrícola
