The pulps are products that add economic value enjoy the fruits of the surplus productions of the same. Have good market acceptance because of its practicality and diversity of flavors available year round. In order to assess the quality of the fruit pulp through the physical and chemical parameters and the characteristics of manufacturing industry, we analyzed 36 samples of frozen fruit pulp of three brands marketed in RIO Grande do Norte, 14 brand A, 12 of 10 brand B and brand C, which corresponded to 14 different flavors, of which 10 have identity Standards and Quality (ISQ S) established by the Ministério da Agricultura, Pecuária e Abastecimento (MAPA), totaling 27 samples with ISQ s. We conducted the following physicalchemical analyzes on samples of fruit pulp: Total solids, total soluble solids, pH, titratable acidity, total sugars and the determination of ascorbic acid. The percentage of failure for each parameter evaluated was 37, 04% in total soluble solids, 22,22% for total solids and titratable acidity, 7,40% in relation to pH. The total sugars were within the requirements demanded by the MAPA and ascorbic acid content, determined only in the pulp of acerola and cashew, presented a non compliance in the pulp of brand B. The percentage of failures of the pulps with ISQ S was 59% with brand A, B and C accounted for 3,70%, 33,33% and 22,22% respectively. The pulps which have no established atandards such as pineapple pulp, showed similar values between brands and literature data unlike the pulp of plum, jackfruit and tamarind which diverged greatly in parameters such as total solids and total soluble solids. The study demonstrates the need for greater quality control by the producers with respect to raw materials, processing, packing, stored and the importance of ISQ S to establish the flavors have not yet covered by existing legislation, but already highly commercialized

The use of intelligent agents in multi-classifier systems appeared in order to making the centralized decision process of a multi-classifier system into a distributed, flexible and incremental one. Based on this, the NeurAge (Neural Agents) system (Abreu et al 2004) was proposed. This system has a superior performance to some combination-centered methods (Abreu, Canuto, and Santana 2005). The negotiation is important to the multiagent system performance, but most of negotiations are defined informaly. A way to formalize the negotiation process is using an ontology. In the context of classification tasks, the ontology provides an approach to formalize the concepts and rules that manage the relations between these concepts. This work aims at using ontologies to make a formal description of the negotiation methods of a multi-agent system for classification tasks, more specifically the NeurAge system. Through ontologies, we intend to make the NeurAge system more formal and open, allowing that new agents can be part of such system during the negotiation. In this sense, the NeurAge System will be studied on the basis of its functioning and reaching, mainly, the negotiation methods used by the same ones. After that, some negotiation ontologies found in literature will be studied, and then those that were chosen for this work will be adapted to the negotiation methods used in the NeurAge.

Aspect-Oriented Software Development (AOSD) is a technique that complements the Object- Oriented Software Development (OOSD) modularizing several concepts that OOSD approaches do not modularize appropriately. However, the current state-of-the art on AOSD suffers with software evolution, mainly because aspect definition can stop to work correctly when base elements evolve. A promising approach to deal with that problem is the definition of model-based pointcuts, where pointcuts are defined based on a conceptual model. That strategy makes pointcut less prone to software evolution than model-base elements. Based on that strategy, this work defines a conceptual model at high abstraction level where we can specify software patterns and architectures that through Model Driven Development techniques they can be instantiated and composed in architecture description language that allows aspect modeling at architecture level. Our MDD approach allows propagate concepts in architecture level to another abstraction levels (design level, for example) through MDA transformation rules. Also, this work shows a plug-in implemented to Eclipse platform called AOADLwithCM. That plug-in was created to support our development process. The AOADLwithCM plug-in was used to describe a case study based on MobileMedia System. MobileMedia case study shows step-by-step how the Conceptual Model approach could minimize Pointcut Fragile Problems, due to software evolution. MobileMedia case study was used as input to analyses evolutions on software according to software metrics proposed by KHATCHADOURIAN, GREENWOOD and RASHID. Also, we analyze how evolution in base model could affect maintenance on aspectual model with and without Conceptual Model approaches

The use of multi-agent systems for classification tasks has been proposed in order to overcome some drawbacks of multi-classifier systems and, as a consequence, to improve performance of such systems. As a result, the NeurAge system was proposed. This system is composed by several neural agents which communicate and negotiate a common result for the testing patterns. In the NeurAge system, a negotiation method is very important to the overall performance of the system since the agents need to reach and agreement about a problem when there is a conflict among the agents. This thesis presents an extensive analysis of the NeurAge System where it is used all kind of classifiers. This systems is now named ClassAge System. It is aimed to analyze the reaction of this system to some modifications in its topology and configuration

The importance of non-functional requirements for computer systems is increasing. Satisfying these requirements requires special attention to the software architecture, since an unsuitable architecture introduces greater complexity in addition to the intrinsic complexity of the system. Some studies have shown that, despite requirements engineering and software architecture activities act on different aspects of development, they must be performed iteratively and intertwined to produce satisfactory software systems. The STREAM process presents a systematic approach to reduce the gap between requirements and architecture development, emphasizing the functional requirements, but using the non-functional requirements in an ad hoc way. However, non-functional requirements typically influence the system as a whole. Thus, the STREAM uses Architectural Patterns to refine the software architecture. These patterns are chosen by using non-functional requirements in an ad hoc way. This master thesis presents a process to improve STREAM in making the choice of architectural patterns systematic by using non-functional requirements, in order to guide the refinement of a software architecture

FUNDAMENTOS: Acne é dermatose comum que acomete ambos os gêneros e todas as faixas etárias. Mulheres apresentam diferentes padrões clínicos da doença, além de frequente persistência da acne após a adolescência. OBJETIVO: Analisar características clínicas e epidemiológicas associadas às diferentes faixas etárias acometidas por acne feminina. MÉTODOS: Estudo transversal envolvendo mulheres com diagnóstico de acne, atendidas em ambulatório de dermatologia geral. Variáveis relacionadas à doença e às pacientes foram avaliadas com o emprego de questionário padronizado. RESULTADOS: Avaliaram-se 103 pacientes, cuja idade média na época da consulta foi 21,7 ± 7,3 anos. Definiram-se dois subgrupos com idade de corte de 21 anos e idades médias de 15,8 ± 2,3 e 28,0 ± 5,1 anos. Houve correlação entre a duração do quadro e a idade das pacientes na consulta (R = 0,7). Observaram-se diferenças entre os grupos nas frequências de uso de contraceptivo oral combinado (OR = 48,1), lesões no colo (OR = 11,6), lesões no dorso (OR = 0,2), predominância na topografia superior da face (OR = 0,1) e idade de início das lesões (OR = 1,8). No grupo de mulheres adultas, 80% relataram início do quadro antes dos 20 anos. CONCLUSÕES: Identificaram-se padrões clínicos cronológicos e topográficos que caracterizaram a acne feminina em diferentes faixas etárias, alertando para a importância da abordagem diagnóstica e terapêutica individualizada.

This study shows the results of a research developed in the coastal regions of the Maxaranguape and Touros municipalities, more specific in the mobile dune fields of the Rio Grande do Norte's eastern coast. Although the coastal zones, represent a small percentage of the earth's surface it concentrates a great part of the world's population. The Rio Grande do Norte's state coastal landscape mosaic composed by the dune fields suggest a dynamic scene of changes in the spatial and temporal arranges, with significant changes in the geometry of the sedimentary cover. Following this perspective this research has the objective to map the emerged coastal zone of the Rio Grande do Norte's eastern coast under the perspective of the time-space evolution of the mobile dune fields using geoprocessing techniques, which includes remote sensing, digital images processing and geographic information system (GIS). The results imply the issue of thematic maps: Geologic map; multitemporal evolution map of the mobile dune fields; quantification of the mobile dune fields differences map; temporal evolution of the mobile dune fields surrounds map. The El Niño episodes have directly affected the atmospheric circulation, what have enhanced the sedimentary input in the sand dune, what can justify the relative area growth between the years of 1993 and 2001. The dynamic of the landscape transition were higher than the stability of the spatial pattern of the dune and it's surrounds, as a result the Rio Grande do Norte eastern coast dune fields, specially the mobile dunes from Touros, Zumbi and Maracajau have shown a decrease on the sedimentary cover without vegetation area from 1970 to 2007. Therefore, the data acquired and the techniques used, can be, eventually applied to the mobile dune fields monitoring in order to preserve the dune ecosystems in the Rio Grande do Norte coast

Os autores relatam os casos de seis crianças com síndrome nefrótica primária grave de padrão histológico renal incomum na rotina cotidiana dos nefrologistas e patologistas. O diagnóstico da doença foi realizado nas faixas etárias de 3 a 9 meses de idade (n = 4), aos 2 anos e 4 meses (n = 1) e aos 11 anos (n = 1). Um paciente foi prematuro, duas pacientes eram irmãs e seus pais eram primos de primeiro grau. Todos apresentavam edema generalizado; dois pacientes apresentavam desnutrição e hipotireoidismo e dois apresentavam hipertensão arterial e insuficiência renal. A histologia renal mostrou esclerose mesangial difusa (n = 3), proliferação mesangial (n = 2) e síndrome nefrótica do tipo finlandês (n = 1). Quatro pacientes faleceram, as causas de óbito foram infecção (n = 2), insuficiência renal (n = 1) e acidose metabólica (n = 1). Entre os sobreviventes, um paciente foi tratado com vitaminas, tiroxina, captopril e indometacina, apresentando aumento da albumina sérica e melhora do crescimento. O outro paciente apresentava insuficiência renal terminal, sendo tratado com diálise e transplante renal.

OBJETIVOS: Avaliar a associação entre os parâmetros clinicolaboratoriais e alteração morfológica de biópsias renais em crianças com síndrome nefrótica. MÉTODOS: Os dados foram obtidos dos prontuários médicos de 43 crianças com síndrome nefrótica submetidas a biópsia renal. RESULTADOS: Vinte e oito pacientes eram do sexo masculino (65,1%), idades entre 1,4 a 12 anos (média de 4,7±3,2). Quarenta e dois pacientes (97,7%) apresentaram edema; 83,7%, oligúria e 32,5%, hipertensão arterial. A média de proteinúria foi 15,3g/1,73m²SC/dia e 55,8% apresentaram hematúria microscópica. As biópsias renais mostraram: glomerulonefrite proliferativa mesangial (GNPM) em 37,2%, glomeruloesclerose segmentar e focal (GESF) em 27,9%, alterações glomerulares mínimas (LM) em 25,6%, glomerulonefrite membranoproliferativa (GNMP) em 7% e glomerulonefrite membranosa (GNM) em 2,3%. Vinte e seis pacientes (60,5%) apresentaram resistência ao corticosteróide. Idade, sexo, hipertensão arterial, oligúria, uréia e creatinina séricas não mostraram diferenças estatísticas significativas entre os pacientes com GNPM, GESF e LM. Os pacientes com GNPM e GESF apresentaram maior freqüência de hematúria microscópica (p < 0,003 e p < 0,03; respectivamente). Os pacientes com GESF apresentaram maiores níveis de proteinúria (p < 0,01 versus LM e p < 0,05 versus GNPM). Os pacientes com LM apresentaram sensibilidade ao corticosteróide (p < 0,001 versus GESF e p = 0,047 versus GNPM). CONCLUSÕES: Sexo, idade, presença de hipertensão arterial ou oligúria e níveis séricos de uréia e creatinina não auxiliaram na diferenciação entre pacientes com GNPM, GESF e LM. Os pacientes com LM apresentaram sensibilidade a corticosteróides e menos probabilidade de apresentar hematúria microscópica. Pacientes com GESF apresentaram maiores níveis de proteinúria.

Canine visceral leishmaniasis is an endemic infectious disease in some São Paulo state regions and even though it is a systemic disease, in the dog, the main clinical sign is dermatological. Thirty dogs with positive results in serology and parasitological exams for leishmaniasis from Aracatuba city were evaluated. They just showed dermatological signs and were divided in two groups, one with exfoliative(n = 15) and other with ulcerative (n = 15) lesions. Histopathological. patterns in the group of exfoliative lesions were: periadnexial dermatitis (5115, 33,3%), superficial perivascular dermatitis (1/5, 6,6%), nodular dermatitis (1115, 6,6%) and mixed dermatitis (8/15, 53,3%), including intersticial/periadnexial dermatitis (1/8, 12,5%). lichenoid/perivascular superficial and deep dermatitis (1/8, 12,5%), perivascular superficial and deep/periadnexial dermatitis (1/8, 12,5%) and superficial perivascular/perianexial dermatitis (5/8, 62,5%). In the group of ulcerative lesions, the histopathological patterns were: perivascular superficial and deep dermatitis (5115, 33,3%), diffuse dermatitis (3/15. 20%), periadnexial dermatitis (2/15, 13,3%), nodular dermatitis (1/15, 6,6%) and mixed dermatitis (4/15, 26,6%), including intersticial/perivascular superficial and deep dermatitis (1/4, 25%), nodular/periadnexial dermatitis (1/4, 25%), fibrosing/perianexial dermatitis (1/4. 25%) and perivascular superficial and deep/periadnexial dermatitis(1/4, 25%). Parasites were found in eight dogs (8/15, 53,3%) with exfoliative dematitis and seven (7/15, 46,6%) with ulcerative dermatitis.

INTRODUÇÃO: A hemiparesia após o acidente vascular encefálico (AVE) é a sequela mais frequente, prejudicando a velocidade de execução dos movimentos automáticos, diminuindo a autonomia do indivíduo e gerando incapacidade. OBJETIVOS: Analisar o efeito da espasticidade nos padrões lineares de marcha (PLM) em indivíduos hemiparéticos. MÉTODOS: Foram estudados dois grupos: 20 indivíduos com AVE (G1) e 20 indivíduos sadios, destros, sem sequela neurológica (G2), com média de idade de 54,2 e 52,6 anos respectivamente. Foram avaliados os PLM pelo protocolo de Nagazaki, o tônus muscular pela escala de Ashworth modificada e o arco de movimento por goniometria. Foi feita comparação dos parâmetros nos dois grupos pelo teste t de Student e correlação de Spearman com nível de significância de 5%. RESULTADOS: A média da distância foi de 14,52 m e 32,16 m, e o tempo foi de 23,75 s e 19,02 s no G1 e G2 respectivamente (p < 0,0001). Na comparação entre os grupos, a amplitude média de passo e a velocidade média foram estatisticamente significantes (p < 0,05) e a cadência não mostrou significância (p = 0,1936). Quando os PLM foram comparados com o grau de espasticidade dos músculos gastrocnêmio e sóleo, mostraram associação negativa com distância, amplitude de passo e velocidade e associação positiva com o tempo (p < 0,05). CONCLUSÃO: Quanto maior o grau de espasticidade dos músculos gastrocnêmio e sóleo, menores serão os parâmetros lineares de marcha do indivíduo com sequela de hemiparesia pós-AVE.

Paclobutrazol applied to the soil is used for the production management of mangoes in most of the orchards, but it presents as disadvantage the greater persistence in plant and soil. Three growth regulators (prohexadione-Ca, trinexapac-ethyl and chlormequat chloride) were foliar applied, at two dosages and compared to paclobutrazol applied as soil-drench. The experiment was conducted in the region of the Sao Francisco Valley, Petrolina, PE, from December 2007 to July 2008, in a mango orchard that has a spacing of 8 m between lines and 5 m between plants. In order to compare the effects of the treatment, data were evaluated regarding to vegetative growth (number, length and leaf number of vegetative branches) and flowering (percentage and panicles length). The combination of PBZ, soil applied with ProCa, foliar applied was the most efficient in controlling vegetative growth of branches of the mango 'Kent', but not regarding to flowering, where there were no differences between treatments.
