Abstract: RESUMO: Sementes de nove cultivares de feij o-comum (Phaseolus vulgaris, L.) (‘Rio Piquiri’, ‘Rio Tibaji’, ‘Paraná-1’, ‘Catu’, ‘Aysó’, ‘Carioca-80’, ‘Aeté-3’, ‘Moruna-80’ e ‘Aroana-80’), duas de feij o-adzuki (Phaseolus angularis (Willd) (Wright) (‘Adzuki 1’ – vermelha e ‘Adzuki 2’ – verde) e cinco de caupi (Vigna unguiculata (L.) Walp). (‘Epace-1’, ‘Epace-6’, ‘Epace-8’, ‘V-76’ ‘V-245’) foram obtidas de 3 épocas de plantio (“águas I” – 26/11/82; “seca” – 07/04/83; “águas II” – 27/09/83 e avaliadas quanto à composi o química e características de hidrata o e cozimento. As características foram significativamente influenciadas pela época de semeadura. Os feij es produzidos na época “águas II” apresentaram valores protéicos significativamente mais elevados do que os das outras duas, e o teor médio foi de 20,75; 16,45 e 23,10 g/100g para o feij o-comum, o adzuki e o caupi, respectivamente. O conteúdo de óleo de feij o comum (1,38 g/100g) correlacionou-se negativamente com o de proteína (-0,64). O de cinzas apresentou o mesmo comportamento que o de proteína quanto às épocas de cultivo, o que n o aconteceu com o de carboidratos. As maiores sementes foram produzidas pela época “águas II” e pelo feijoeiro-comum (20,38 g/100 sementes) com destaque para os cvs, Moruna-80, Paraná-1, e Carioca-80. Para o caupi este valor foi de 19,48g e para o adzuki, de 7,79g. Os gr os cultivados nas épocas “águas I” e “águas II” apresentaram melhor hidrata o (RH = 1,94), e estes os maiores conteúdos de gr os “hardshell”, com destaque para os cvs. Carioca-80 (7,4%), Adzuki-1 (14,2%), Aysó (19,5%), Epace- (19,5%) e V-245 (31,0%). O tempo de cozimento foi maior para os gr os produzidos na época “águas I” e, dentre os cultivares, os de Vigna foram os que apresentaram os menores tempos, nas três épocas (13,17 minutos), quando comparados com os de feij o-comum (25,47 minutos) e de feij o-adzuki (104,10 minutos). PALAVRAS–CHAVE: Feij o-comum; feij o-adzuki; caupi; épocas de cultivo; composi o química; hidrata o; cozimento.

Acta Cirurgica Brasileira , 2010, DOI: 10.1590/S0102-86502010000500011
Abstract: purpose: to compare chemical to morphological kidney stone composition analysis based on a sample of 50 stones retrieved from patients at a nephrology service. methods: the chemical analysis was performed with a bioclin? kit, while a 10-mm magnifying glass (10x; prolabo, paris, france) was employed in the morphological analysis. findings obtained with the two methods were compared and classified as concordant (100% agreement), partly concordant (concordant for major components, discordant for minor components) or discordant (discordant for major components). results: in the chemical analysis, the most commonly observed major component was calcium (70%), followed by oxalate (66%), ammonium (56%), urate (28%) and carbonate (24%). in the morphological analysis, the most commonly observed major components were calcium phosphate and magnesium (32% each), followed by calcium oxalate monohydrate (24%), uric acid and urates (20% each), calcium oxalate dihydrate (18%) and cystine (6%). infectious kidney stones were identified in 34% and 24% of cases by morphological and chemical analysis, respectively. thirty-eight percent of the samples were classified as concordant, 52% were partly concordant and 10% were discordant. conclusion: we suggest kidney stones be routinely submitted to both types of analysis for a better understanding of the mechanisms involved in lithogenesis.

Abstract: purpose: the purpose was to evaluate a novel technique for isolation of walker's tumoral cells using a ficoll-hypaque gradient and its further influence on tumor development. methods: twenty male wistar rats have been divided in 2 groups: g1= without ficoll, g2= with ficoll. tumor was excised, homogenized and suspended in lactate ringer. a sample of the cell suspension was adjusted at a concentration of 1x106 cells/ml (g1). a second sample was centrifuged on a ficoll-hypaque gradient and the cell concentration was then adjusted (g2). tumor was implanted by subcutaneous injection of 1.0 ml in the right armpit of rats. tumor volume (tv) and tumor weight (tw) were compared in two groups. results: there were no differences between the two groups in tv (g1=17.9±3.8cm3 vs. g2=17.2±4.4cm3; p=0.190) and tw (g1=7.0±1.8g vs. g2=7.3±2.8g; p=0.569). the histological analysis showed similar patterns of infiltration by small-undifferentiated cells and necrosis in both groups. however, a mild to moderate granulocytic exsudate was more frequent in the animals whose tumors derived from ficoll-isolated cells. hemorrhage from slight to moderate was only observed in this group. conclusion: a ficoll-hypaque gradient can provide more adequate isolation of walker's tumor and the cell suspension obtained by this technique has lower contamination by other cell types.

Abstract: this descriptive exploratory study analyzed user satisfaction with the care received at a family health unit in ribeir?o preto, brazil. in total, 40 users from families registered in the fhu were selected, using key informants and the snowball sampling technique, and interviewed. thematic content analysis was used to analyze the empirical material. interviewees were mostly female, over 50 years, resident in the catchment area of the unit for 10-30 years, had incomplete primary education and also did not perform work outside the home. the analysis identified three themes: access, team-user interaction and organization of work in the fhu. the subjects of this study expressed satisfaction with the accessibility provided together with the caring attention given to them, marked by a team-user interaction that takes place in a friendly and patience manner. although not totally satisfied, the majority of users would recommend the health service to someone due to its quality.
An Algorithm for Finding Minimum d-Separating Sets in Belief Networks
Silvia Acid,Luis M. de Campos
Computer Science , 2013,
Abstract: The criterion commonly used in directed acyclic graphs (dags) for testing graphical independence is the well-known d-separation criterion. It allows us to build graphical representations of dependency models (usually probabilistic dependency models) in the form of belief networks, which make easy interpretation and management of independence relationships possible, without reference to numerical parameters (conditional probabilities). In this paper, we study the following combinatorial problem: finding the minimum d-separating set for two nodes in a dag. This set would represent the minimum information (in the sense of minimum number of variables) necessary to prevent these two nodes from influencing each other. The solution to this basic problem and some of its extensions can be useful in several ways, as we shall see later. Our solution is based on a two-step process: first, we reduce the original problem to the simpler one of finding a minimum separating set in an undirected graph, and second, we develop an algorithm for solving it.

Abstract: Actinic cheilitis can progress to squamous cell carcinoma in 20% of cases. The purpose of this study was to identify the clinical characteristics of 75 patients with actinic cheilitis and to summarise the current literature concerning actinic cheilitis. A total of 75 patients were evaluated over a 3-year period. The medical history, physical examination results and images were collected from each patient. Demographic data were collected and analysed. To review the literature, the relevant data were collected from scientific journals in the last 30 years. The mean age of the patients was 56 years old; 42 patients (56%) were female, and 66 patients (88%) were white. Nineteen (25.3%) patients reported at least one symptom, including pain, burning and itching. Sixty-five (86.7%) patients presented actinic cheilitis only in the lower lip. All of the patients reported sun exposure, and 44 (58.6%) patients were exposed for more than 10 years. The main clinical aspects investigated and analysed included dryness (100%), flaking (72%) and white lesions (57.3%). Lip assessment is extremely important in medical and dental care. From the 15 lesions assessed in the presence of actinic cheilitis, the most common clinical characteristics observed were dryness, flaking and white lesions. It is imperative to know the clinical aspects that may be encountered in actinic cheilitis in order to achieve early diagnosis, thus avoiding lip squamous cell carcinoma transformation.
Issues on beam-plasma instability: early simulations focusing on the development of a compact neutron generator

Revista Brasileira de Ensino de Física , 2010, DOI: 10.1590/S1806-11172010000300002
Abstract: the first issue on compact neutron generator design is the definition of the plasma generation process following the analysis of the physical plasma state. the plasma features and the nuclear reactions of fusion involved in the operation of the generator, deuterium-deuterium or deuterium-tritium, as well as the system which determines the trajectories of the particles and the target, are decisive to predict the neutron yield from the generator. hence, the plasma behavior analysis under established conditions becomes an important evidence. this analysis may be done by means of plasma simulation models. particle simulation of plasmas, employed since 1960s, provides a picture of the general plasma characteristics. plasma physics is determined in most cases by simple equations, i.e. equations of motion of electrons, ions and neutrals atoms including the effect of collisions and self-consistent electric and magnetic fields. computer simulation of plasmas comprises two general areas based on kinetic and ?uid. while ?uids simulation proceeds by solving numerically the magnetohydrodynamic (mhd) equations, assuming approximate transport coefficients, kinetic simulation considers more detailed models of plasma involving particle interactions through the electromagnetic fields. this article is focused on the simulation and analysis of injected beam into a steady state and periodic plasma. the applied calculation model, for this simulation purpose, is referring to an electrostatic one dimension code, based on kinetic simulation, which simulates periodic plasmas illustrating various fundamental considerations of plasma simulation and make it useful in simulations of the beam optic system for neutron generators. the main goal of this research is explore the pic code reviewing the computational and physics theory necessary to build the structure of the elementary principles intending to introduce concepts of plasma physics and the computational theory. moreover, foundations of pla
