Abstract: The objective of this study was to identify and quantify fungi associated with seeds ipe-pink (Tabebuia impetiginosa), yellow-ipe (Tabebuia ochracea) and evaluate the effects of aseptic seed germination and seed seeding. The experiment was done at the Laboratory of Plant Science Center of Agrarian Sciences, Federal University of Roraima. Samples of ipê yellow and pink ipe were collected and extracted from fruits harvested in the urban area of the city of Boa Vista - RR. Each sample was divided into two sub-samples, treated and untreated, and were then submitted to germination and health analyses. The filter paper method was used for the health test where contaminated seeds were analyzed for the detection and identification of fungi. For the germination test method was also the filter paper, obtained the germination rate, rate of plants with lesions, number of seeds germinated and the rate of non-germinated seeds that had fungus. The results were subjected to variance analysis and when significant, means were compared by the Tukey test at 5% probability. The experimental design was completely randomized with four replications of 50 seeds for each treatment. Asepsis with 70% alcohol for a minute then with sodium hypochlorite (NaClO) to 2% for three minutes was positive for the elimination of fungi on seeds of ipe-yellow and ipe-pink, it favored germination and decreases the rate of seedlings with lesions. = Objetivou-se com o presente trabalho identificar e quantificar os fungos associados às sementes de ipê-rosa (Tabebuia impetiginosa), ipê-amarelo (Tabebuia ochracea) e avaliar o efeito da assepsia das sementes na germina o e na plantula.

Abstract: Tomato (Solanum lycopersicon) is cultivated on a large scale in Brazil and worldwide. Due to the fact that it has a relatively short cycle and higher yields, the tomato crop has good economic prospects and the cultivated area is increasing dayle. The aim of this study was to evaluate the physical and chemical characteristics of fruits of different tomato accessions in the greenhouse conditions in Boa Vista-RR. The following accessions were evaluated: 18 (cherry tomato), 209 (cherry tomato),243 (CNPH 738), 101 (tomato Santa Cruz - KADA), 102 (tomato Yoshimatsu), and 246 (CNPH 0171). The experiment was conducted in a completely randomized design with six treatments and four replications. The fruit at the point of harvest, were collected properly identified and evaluated for the following characteristics: vitamin C content, pH, acidity, soluble solids, soluble solids /acidity, fresh, transverse and longitudinal diameter of the fruit, the pericarp thickness and dry matter content. The data were subjected to variance analysis and means were compared by Duncan test at 5% probability. Except for the variable content of soluble solids, the other variables showed statistical differences. All accesses have attributes suitable for eating raw. With the exception of access 101 and 102 due to high pH (Access 101) and low dry matter content (access 101 and 102), others have attributes suitable for industrial processing.=O tomate (Solanum lycopersicon) é cultivado em grande escala na agricultura brasileira sendo uma das culturasmais difundidas em todo mundo. Por se tratar de uma cultura de ciclo relativamente curto e de altos rendimentos, a culturado tomate tem boas perspectivas econ micas e a área cultivada vem aumentando a cada dia.

Abstract: O pinh o-manso (Jatropha curcas L.), da família Euforbiaceae, é uma espécie que pode ser cultivada em diferentes condi es edafoclimáticas. Apresenta valor medicinal, ornamental e na produ o de óleo. Atualmente tem aumentado o interesse no conhecimento agron mico desta cultura, visando à sele o e o aprimoramento de variedades mais produtivas e economicamente viáveis, principalmente devido ao alto potencial na produ o de óleo para fabricar o biodiesel. Apesar de ainda n o ser cultivada comercialmente no Brasil, mostra-se viável para a agricultura familiar das regi es Norte e Nordeste, pois tem alta resistência à seca e boa adapta o as altas temperaturas e insola o, além de produzir em solos ácidos e de baixa fertilidade como os do cerrado da Amaz nia. Estudos est o sendo conduzidos com essa cultura no estado de Roraima visando desenvolver tecnologias viáveis de produ o para serem adotadas pela agricultura familiar, como uma alternativa promissora na gera o de emprego e renda, promovendo a recupera o e prote o de áreas alteradas ou degradadas e permitindo o consórcio com fruteiras nativas e culturas anuais. = The pinh o-manso (Jatropha curcas L.), from the Euforbiaceae famíly, is a species that can be raised in different edafoclimatic conditions. It presents a regular medicinal and ornamental value, and it is also useful for oil production, Nowadays it is increasing the interest in the agronomic knowledge of this culture, mostly related to the selection and improving of more productive and economically feasible varieties, mainly due to its high potencial for biodiesel production. Although this species is not yet cultivated for market use in Brasil, it has shown feasibility for family agriculture in North and Northeast regions, because of its great resistance to draught as well as its good adaptation to high temperatures and insolation. This species can also produce in highly acid and scarcely fertile soils, such as those in the Amazonian savannah. There are various studies in progress dedicated to this culture in Roraima state, and through these studies, it may be achieved a possibility to develop feasible production technologies that could be adopted by family agriculture. That would show a promising alternative for job creation and better income, fostering the recovering and protection of modified areas, and promoting the organization of native fruit and annual cultures consortiums.
La thèse de Feldstein-Horioka: Ue mesure de la mobilité internationale du capital

Abstract: (portugalski) Nous présentons la thèse de Feldstein-Horioka (F-H) sur la mobilité du capital et les développements qu’elle a suscités. Il s’agit d’une thèse qui est très ouverte à la possibilité de réfutation et dont l’histoire illustre bien la pensée méthodologique nonna ve de Karl Popper: les discussions sur sa réfutation, en parallèle avec les tentatives de consolidation ("d’immunisation"), au sens de K. Popper, ont conduit à de nouvelles lectures sur la mobilité du capital. Ces efforts de consolidation (d’ "immunization") ont conduit cette thèse à intégrer des nouvelles méthodologies économétriques et à changer partiellement son objet, en mesurant aussi la soutenabilité externe. La thèse de F-H constitue un cas exemplaire d’intégration de l’analyse théorique et d’analyse empirique.

Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.32010
Abstract:

Coauthorship networks consist of links among groups of mutually connected authors that form a clique. Classical approaches using Social Network Analysis indices do not account for this characteristic. We propose two new cohesion indices based on a clique approach, and we redefine the network density using an index of variance of density. We have applied these indices to two coauthorship networks, one comprising researchers that published in Mathematics Education journals and the other comprising researchers from a Computational Modeling Graduate Program. A contextualized and comparative analysis was performed to show the applicability and potential of the indices for analyzing social networks data.

Abstract: complementary exams are routinely done before middle and large surgical procedures. however, their necessity is questionable since most of them are usually normal or their results are previously supposed. in order to verify the usefulness of preoperative exams to prevent surgical complications, the present investigation took place. we revised 117 charts of patients submitted to large abdominal (66,6%) and/or thoracic (33,4%) operations for trauma at lhe emergency of the jo?o xxiii hospital of belo horizonte, between 1985 and 1995. all patients were identified and their preoperative exams and the postoperative complications were assessed. the age of the 76 men and 41 women ranged between 20 and 79 years old. most of the exams (49,2%) were abnormal, but all findings were supposed by the clinical exams. only 1,6% of these abnormalities were related to postoperative complications. no postoperative complication was related to the 70,4% radiographic abnormalities. the most common complications were wound abscess, cardiopulmonary arrest and pneumonia. none of the complications could be prevented by any complementary exam. in the present study, the results of the preoperative exams did not modify the approach of the patients and their alterations had not influence on the postoperative complications.

Abstract: Objectives: To determine prevalence, incidence and risk factors of delirium in hospitalized patients in the infirmary of medical clinic of the Lauro Wanderley University Hospital. Method: An observational cohort study evaluating 140 patients over 18 years between admission and discharge. The survey instrument was the Confusion Assessment Method. Results: The prevalence of delirium was 5.7% (8/140) and the incidence, 2.1%. In patients with delirium were observed alteration of sleep-wake cycle (6/75%), altered level of consciousness (6/75%), disorganized thinking (5/62, 5%) and psychomotor retardation (5/62 5%). There was a significant association of delirium and age, mechanical restraint in bed, prior history of cognitive impairment, auditory and visual sensory deficit, psychiatric hospitalization, poor health status and mortality. Conclusions: The prevalence of delirium at admission was lower than that found in other studies, but it was a predictor factor of hospital mortality.

Abstract: the population increase of the city of manaus has propelled the ornamental stones business sector to procure raw-material of quality and beauty (granites, gneisses, marble, etc.) in the southeastern region of brazil at a cost up to six times more expensive. however, the northeastern region of the state of amazonas hosts paleoproterozoic granitic massifs with great potential for use as ornamental stones, which have onely been extracted for crushed-stone production. this paper presents the textural, petrographic, and geochemical characteristics, as well as technological indices (porosity, density, water absorption, uniaxial compression, ultrasonic pulses, resistance to flexion and amsler degeneration) for samples from five granitic massifs exposed in the northeastern region of the state of amazonas. the obtained data suggest that the granite massifs can be used as ornamental stones, but applicable in places with moderate transit, low humidity and free of acidic attacks. considering the favorable technical parameters and the relative proximity of the granite massifs to the city of manaus (about 140 to 240 km), which is a consumer centre with 2 million inhabitants, the investment in the extraction of ornamental stones in the northeast of amazonas becomes an option, at least, interesting for the business sector.
