Produção de mudas de açaí sob diferentes níveis de depleção de água associada a doses de um polímero hidroabsorvente

O açaizeiro é uma palmeira com potencial comercial valorizado principalmente pela polpa do fruto que possui propriedades químicas benéficas à saúde humana. Os produtores necessitam corresponder ao incremento de demanda e a produção de mudas deve contemplar essa tendência de mercado. O conhecimento a respeito do manejo hídrico de mudas da espécie ainda pode ser ampliado e a utilização de polímero hidroabsorvente (hidrogel) na produção de mudas da espécie surge como uma opção para redução de custos em irrigação associada a uma boa qualidade das plantas. O objetivo deste estudo é gerar informações que correlacionem a influência de doses de hidrogel à produção de mudas de açaizeiro em diferentes regimes hídricos. O experimento foi conduzido no Departamento de Engenharia de Biossistemas da Escola Superior de Agricultura \"Luiz de Queiroz\". O delineamento utilizado foi o de blocos ao acaso sob os seguintes tratamentos, quatro doses de hidrogel (0; 1,0; 2,0; 3,0 g L-1) e três níveis de depleção (0-5; 25; 50% da capacidade de retenção de água do substrato com o polímero) com quatro repetições. O experimento foi conduzido por 9 meses e ao final foram realizadas avaliações biométricas e análises destrutivas para obtenção de valores de massa seca. Para embasamento estatístico dos dados aplicou-se o teste F, em 1 e 5% de probabilidade, análise de regressão polinomial e o teste de Tukey em 5% de probabilidade. O hidrogel aumentou a capacidade de retenção hídrica do substrato e os resultados mostraram que a presença do polímero acrescentou qualidade à muda de forma crescente em função das doses; todavia, doses de 3g L-1 podem acarretar problemas com drenagem devido à perda de eficiência de absorção do polímero. Os níveis de depleção (25 e 50%) afetaram substancialmente, de forma negativa, o desempenho da muda quando comparados ao tratamento de menor depleção (0-5%), demonstrando que a espécie é bastante sensível a regimes com menor disponibilidade hídrica. Não foi observado efeito de interação entre as doses do polímero e os níveis de depleção para a grande maioria das variáveis analisadas, com exceção apenas da área foliar específica (AFE) e da irrigação aplicada (IA). O Kc médio da cultura, para cultivo protegido, apresentou tendência crescente ao longo do experimento. Conclui-se que a melhor dose do polímero é de 2 g L-1 e que o nível de depleção de 0-5% apresentou o melhor desempenho. O Kc determinado mostra tendência de acordo com a fase de desenvolvimento da espécie, variando de 0,76 até 1,41.

Reconocimiento óptico de caracteres mediante imágenes en contadores de gas

La gran evolución a lo largo de este tiempo sobre dispositivos móviles y sus características, así como las vías de conexión de alta velocidad 3G/4G, han logrado dar un giro a los planteamientos económicos empresariales consiguiendo que se replanteen los costes de sus infraestructuras tradicionales, involucrando las nuevas tecnologías en su nueva estructura económica y consiguiendo invertir menos recursos humanos en el proceso de producción. Este proyecto propone una solución real para la empresa Madrileña Red de Gas. Mientras el proyecto de contadores inteligentes se termina de concretar y desarrollar, es necesario disponer de un método que automatice la lectura de los contadores analógicos mediante el procesamiento de una imagen digital a través de una aplicación informática que sea capaz de determinar el código de identificación del contador así como la lectura del consumo actual. Para la elaboración del método desarrollado se han utilizado conceptos propios de Visión por Computador y de Aprendizaje Automático, más específicamente tratamiento de imágenes y reconocimiento óptico de caracteres, mediante la aplicación de métodos en el ámbito de dichas disciplinas.

Saving the Monopsony: Exclusivity, Innovation and Market Power in the Media Sector. Research Papers in Law, 7/2006

From the Introduction. The Media Sector has experienced a technological revolution in the last 15 years. Digital encoding of television signals made possible a more efficient use of the radiospectrum. Digital terrestrial television (hereinafter, “DTT”) allows now for the reception of a significant number of free-to-air channels.1 Moreover, the use of new transmission platforms (hereinafter,“platforms”), namely cable and direct-to-home satellite (hereinafter, “DTH”) paved the way for the arrival in Europe of pay-TV operators, which finance their activities mainly via subscription fees. This changing technological landscape is subject to further evolution in the near future, as incumbent telecommunications operators become increasingly interested in making available broadcasting content2 as part of their broadband offer and 3G mobile handsets can be used for the reception of TV signals....The present paper seeks to ascertain whether the Commission “regulatory approach” towards the exclusive sale of premium content is a sound one, in particular in view of the constant technological evolution outlined above. The assumptions underlying landmark Commission decisions will be compared with recent developments of the media sector in Italy. In the NewsCorp./Telepiù case, decided in 2003, the Commission imposed very strict conditions to allow the merger giving birth to Sky Italia, on the assumption that the operation created a lasting near-monopsony in the different upstream markets for the acquisition of premium intervened against the media conglomerate Mediaset (which controls, inter alia, the main three private free-to-air channels in Italy) for an alleged abuse of dominant position.17 In fact, and contrary to the forecasts made by the Commission, Mediaset was in a position to acquire the broadcasting rights of the main Italian football teams, thereby excluding the incumbent (and near-monopolist) pay-TV operator, Sky Italia. This may go to show that the reality of the sector is more complex and evolves faster than one may infer from the Commission practice, thus putting into question its stance regarding exclusivity. The experience of the evolution of the Italian media sector will be used as the starting point for the evaluation of alternative regulatory options.

The sutureless aortic valve at 1 year: A large multicenter cohort study

OBJECTIVE Sutureless aortic valve replacement (AVR) offers an alternative to standard AVR in aortic stenosis. This prospective, single-arm study aimed to demonstrate safety and effectiveness of a bovine pericardial sutureless aortic valve at 1 year. METHODS From February 2010 to September 2013, 658 patients (mean age 78.3 ± 5.6 years; 40.0% octogenarian; 64.4% female; mean Society of Thoracic Surgeons score 7.2 ± 7.4) underwent sutureless AVR in 25 European centers. Concomitant cardiac procedures were performed in 29.5% and minimally invasive cardiac surgery in 33.3%. RESULTS One-year site-reported event rates were 8.1% for all-cause mortality, 4.5% for cardiac mortality, 3.0% for stroke, 1.9% for valve-related reoperation, 1.4% for endocarditis, and 0.6% for major paravalvular leak. No valve thrombosis, migration, or structural valve deterioration occurred. New York Heart Association class improved at least 1 level in 77.5% and remained stable (70.4% New York Heart Association class I or II at 1 year). Mean effective orifice area was 1.5 ± 0.4 cm(2); pressure gradient was 9.2 ± 5.0 mm Hg. Left ventricular mass decreased from 138.5 g/m(2) before surgery to 115.3 g/m(2) at 1 year (P < .001). Echocardiographic core laboratory findings confirmed that paravalvular leak was rare and remained stable during follow-up. CONCLUSIONS The Perceval sutureless valve resulted in low 1-year event rates in intermediate-risk patients undergoing AVR. New York Heart Association class improved in more than three-quarters of patients and remained stable. These data support the safety and efficacy to 1 year of the Perceval sutureless valve in this intermediate-risk population.

AMS C-14 ages of coretops collected on RRS Charles Darwin cruise CD159, July 2004, N. Atlantic, for the NERC RAPID programme

Material and data were collected at 41 sites in the subpolar North Atlantic Ocean between Scotland and Newfoundland, during the RRS CharlesDarwin CD159 cruise in July 2004 (McCave, 2005). Sites were selected to reflect the major inputs of water that becomes the North Atlantic Deep Water (NADW); the Iceland-Scotland Overflow Water (ISOW), the Denmark Strait Overflow Water (DSOW) and the Labrador Sea Water (LSW). Areas cored were the south Iceland Rise, SE Greenland slope/rise and Eirik Drift, and the Labrador margin. A total of 29 box cores, 19 piston cores, 6 kasten cores, 9 short gravity cores and 20 CTD casts as well as 28 surface water samples were collected during the cruise. Here we present sediment core-top sample ages. The cores were sampled at 1 or 0.5 cm intervals and we used the top 1 or 2 cm, depending on availability of foraminifera in the samples. Sediment samples were disaggregated on an end-over-end wheel, wet sieved at >63 um, and dry sieved to 63-150 and >150 um. Accelerator Mass Spectrometer (AMS) radiocarbon dating was done for each core top based on between 900-1600 monospecific planktonic foraminifera (Globigerina bulloides or Neogloboquadrina pachyderma (sinistral)). All dates were of modern or late Holocene age except site RAPID-08-5B (9806 ± 38 uncorrected 14C years BP) and site RAPID-14-10B (11543 ± 40 uncorrected 14C years BP). The >150 um fraction was split until approximately 300 foraminifera remained and counted for number of lithic grains, benthic foraminifera, planktonic foraminifera and foraminifera fragments. In all but the shallowest sample (Greenland rise, 761m water depth) benthic foraminifera constituted less than 2% of the total >150 um fraction of the sample.
