Variación fenotípica y correlación de rendimiento con características morfo-agronómicas en una población de maíz (Zea mays L.) variedad NB-6 en la época de primera, Sábana Grande, Managua, 2014.

Con el objetivo de describir variación fenotípica y correlación de rendimiento con características morfo-agronómicas en una población de maíz (zea mays L.) variedad NB-6 en la época de primera, Sábana Grande, Managua, 2014, se estableció un ensayo en la Finca Santa Rosa Sabana Grande, Managua propiedad de la Universidad Nacional Agraria. La muestra consistió en 93 individuos para caracteres del tallo y hoja, diámetro del tallo (DiamT), altura de la mazorca (AltM), número de hojas (Nho), longitud de la hoja (LonHo), ancho de la hoja (AncHo), altura de la planta (AltP), y 393 individuos para rasgos asociados al rendimiento, longitud de la mazorca (LM), diámetro de la mazorca (DM), número de hilera por mazorca (NH), granos por hilera (GH), peso de granos de la mazorca (PGMAZ), peso de 100 granos (P100G) y peso de la mazorca (PMAZ). El análisis de los datos consistió en estadísticos descriptivos: media, desviación estándar, coeficiente de variación, valores máximos y mínimos, así como correlaciones entre variables morfológicas, correlaciones entre variables asociadas al rendimiento. Finalmente mediante regresión paso a paso (stepwise) se determinaron parámetros de estimación del rendimiento en grano a través de las variables PMAZ y GH. La media y desviación estándar para los caracteres evaluados fueron, 2.21±0.21 AltP, 1.14±0.17 AltM, 94.71±8.18 LonHo, 14.33±1.17 Nho,10.51±0.92 AncHo, 22.81±2.53 DiamT, 16.56±1.83 LM,48.22±3.48 DM, 14.39±1.83 NH, 33.85±4.74 GH, 183.65±40.15 PMAZ, 153.20±33.39 PGMAZ, 34.38±6.08 P100G. El coeficiente de variación mostró valores entre 14.88 y 8.13 % para los caracteres de tallo y hoja correspondientes a AltP y Nho respectivamente. Hubo correlación positiva y significativa AltP con AltM y LonHo (0.74, 036) y DiamT y AncHo (0.39). Para los caracteres relacionados al rendimiento el coeficiente de variación mostró valores entre 21.86 y 7.21 correspondiente a PMAZ y PGMAIZ. Se encontró correlación positiva y significativa para la mayoría de variables del rendimiento exceptuando DM con NH que fue significativa y negativa y LM y NH que no mostraron correlación. El PGMAZ mostró correlaciones positivas y significativas, el resto de variables asociadas al rendimiento con valores que oscilaron entre 0.95 y 0.19 la de mayor correlación fue el PMAZ. El peso de la mazorca contribuyó mas (R2 0.99) al ajuste del modelo de estimación seguido por el número de granos por hilera, para la ecuación final: Yij = 0.7705X1 + 0.3470X2, que puede ser utilizada en selección fenotípica inicial.

An examination of the utility of the AUDIT in people with schizophrenia

Objective: To examine the reliability and validity of the Alcohol Use Disorders Identification Test (AUDIT) compared to a structured diagnostic interview, the Composite international Diagnostic Interview (CIDI; 12-month version) in psychiatric patients with a diagnosis of schizophrenia. Method: Patients (N = 71, 53 men) were interviewed using the CIDI (Alcohol Misuse Section; 12-month version) and then completed the AUDIT. Results: The CIDI identified 32.4% of the sample as having an alcohol use disorder. Of these, 5 (7.0%) met diagnostic criteria for harmful use of alcohol, 1 (1.4%) met diagnostic criteria for alcohol abuse and 17 (23.9%) met diagnostic criteria for alcohol dependence. The AUDIT was found to have good internal reliability (coefficient = 0.85). An AUDIT cutoff of greater than or equal to 8 had a sensitivity of 87% and specificity of 90% in detecting CIDI-diagnosed alcohol disorders. All items except Item 9 contributed significantly to discriminant validity. Conclusions: The findings replicate and extend previous findings of high rates of alcohol use disorders in people with severe mental illness. The AUDIT was found to be reliable and valid in this sample and can be used with confidence as a screening instrument for alcohol use disorders in people with schizophrenia.

The Australian Nonprofit Sector Legal Almanac 2010, ACPNS Working Paper 53

This is the third year that we have summarised annual developments in the law for nonprofit staff, boards and volunteers. We were encouraged by the interest shown in last year’s publication and the use made of the digital copy on our web site, so here is the almanac for the Jan 2010–Dec 2010 period. We are delighted that the Australian Charity Law Association and PilchConnect (Victoria) have again agreed to contribute and promote the publication as well. These two organisations are beginning to fill the void of professional legal development and assistance to small nonprofit organisations that has characterised Australia for too many years. The first conference of the Australian Charity Law Association in Sydney was a significant event and one of the addresses is included in the Almanac. Other materials from the conference can be accessed at the Centre’s website.

Timing and emplacement dynamics of newly recognised mass flow deposits at ~ 8–12 ka offshore Soufrière Hills volcano, Montserrat : how submarine stratigraphy can complement subaerial eruption histories

This contribution describes two mass movement deposits (total volume ~0.5 km3) identified in seven marine cores located 8 to 15 km offshore southern Montserrat, West Indies. The deposits were emplaced in the last 35 ka and have not previously been recognised in either the subaerial or distal submarine records. Age constraints, provided by radiocarbon dating, show that an explosive volcanic eruption occurred at ca 8–12 ka, emplacing a primary eruption-related deposit that overlies a large (~0.3 km3) reworked bioclastic and volcaniclastic flow deposit, formed from a shelf collapse between 8 and 35 ka. The origin of these deposits has been deduced through the correlation of marine sediment cores, component analysis and geochemical analysis. The 8–12 ka primary volcanic deposit was likely derived from a highly-erosive pyroclastic flow from the Soufrière Hills volcano that entered the ocean and mixed with the water column forming a water-supported density current. Previous investigations of the eruption record suggested that there was a hiatus in activity at the Soufrière Hills volcano between 16 and 6 ka. The ca 8–12 ka eruptive episode identified here shows that this hiatus was shorter than previously hypothesised, and thus highlights the importance of obtaining an accurate and completemarine record of events offshore from volcanic islands and incorporating such data into eruption history reconstructions. Comparisons with the submarine deposit characteristics of the 2003 dome collapse also suggests that the ~8–12 ka eruptive episode was more explosive than eruptions from the current eruptive episode.

Apsidal motion in 4U 0115+63 and orbital parameters of 2S 1417-624 and V0332+53

Be/X-ray binary pulsars have wide eccentric orbits and hence the angle of periastron of the orbit is very well defined in these sources. The presence of an X-ray pulsar allows for accurate measurements of orbital elements. A Be star usually is a rapidly rotating star and hence will deviate from spherical geometry. The tidal interaction between the neutron star and the Be star will add to the distortion of the Be star and alter its mass distribution. Thus a measurable rate of apsidal motion is expected from these systems. In this paper, we present the first conclusive detection of apsidal motion of the binary 4U 0115+63. We also present new and accurate orbital parameters of the Be/X-ray binaries V0332+53 and 2S 1417-624.

Effect of neodymium (Nd) doping on the dielectric and ferroelectric characteristics of sol-gel derived lead zirconate titanate (53/47) thin films

The results of the studies on the effect of rare earth Nd doping on the phase formation behavior and electrical properties of sol-gel derived Pb-1.05(Zr0.53Ti0.47)O-3 (PZT) thin films are presented. The perovskite phase is obtained up to 5 at. % doping and beyond that pyrochlore phase was found to coexist with the perovskite phase in all the films. The transition temperature of undoped lead zirconate titanate (PZT) film was found to be reduced with Nd doping. The Nd doped films also exhibited typical relaxor-type behavior and a diffuse phase transition, similar to that observed in relaxor materials. The introduction of Nd into the PZT lattice probably introduces disorder in the B site of ABO(3) lattice, which causes the observed dielectric relaxation. Efforts were made to isolate the irreversible component contributions in low field dielectric and high field polarization switching behavior. (C) 2001 American Institute of Physics.

Chromium isotope variations (delta Cr-53/52) in mantle-derived sources and their weathering products: Implications for environmental studies and the evolution of delta Cr-53/52 in the Earth's mantle over geologic time

Here we report chromium isotope compositions, expressed as delta Cr-53/ 52 in per mil (&) relative to NIST 979, measured in selected Cr-rich minerals and rocks formed by the primary magmatic as well as the secondary metamorphic and weathering processes. The main objectives of this study were: (i) to further constrain the isotope composition of the Earth's mantle Cr inventory and its possible variation during geological history, based on the analysis of globally distributed and stratigraphically constrained mantle-derived chromites; and (ii) to investigate the magnitude and systematics of Cr isotope fractionation during oxidative weathering and secondary alteration (i. e., hydration, serpentinization) of the magmatic Cr sources. Specifically, we analyzed delta Cr-53/ 52 in a set of globally distributed mantle-derived chromites (FeMgCr2O4, n = 30) collected from various locations in Europe, Asia, Africa and South America, and our results confirm that a chromite-hosted Earth's mantle Cr inventory is uniform at - 0.079 +/- 0.129& (2SD), which we named here as a ` canonical' mantle d 53/ 52 Cr signature. Furthermore our dataset of stratigraphically constrained chromites, whose crystallization ages cover most of the Earth's geological history, indicate that the bulk Cr isotope composition of the chromite-hosted mantle inventory has remained uniform, within about +/- 0.100&, since at least the Early Archean times (similar to 3500 million years ago, Ma). To investigate the systematics of Cr isotope fractionation associated with alteration processes we analyzed a number of secondary Cr-rich minerals and variably altered ultramafic rocks (i. e., serpentinized harzburgites, lherzolites) that revealed large positive delta Cr-53/ 52 anomalies that are systematically shifted to higher values with an increasing degree of alteration and serpentinization. The degree of aqueous alteration and serpentinization was quantified by the abundances of fluid-mobile (Rb, K) elements, and by the Loss On Ignition (LOI) parameter, which determines the amount of structurally bound water (OH/ H2O) present in secondary hydrated minerals like serpentine. Overall, we observed that altered ultramafic rocks that yielded the highest LOI values, and the lowest amounts of fluid mobile elements, also yielded the heaviest delta Cr-53/ 52 signatures. Therefore, we conclude that secondary alteration (i.e., hydration, serpentinization) of ultramafic rocks in near-surface oxidative environments tend to shift the bulk Cr isotope composition of the weathered products to isotopically heavier values, pointing to a dynamic redox cycling of Cr in the Earth's crustal and near-surface environments. Hence, if validated by future

Deputados brasileiros : repertório biográfico : 53ª legislatura, 2007-2011

Reúne as informações pessoais e sobre a vida profissional e política dos 513 deputados eleitos no pleito de 3 de outubro de 2006, no momento inicial da 53ª Legislatura, tendo por objetivo constituir-se em importante fonte de pesquisa e de preservação da memória da Câmara dos Deputados.

Emendas individuais ao orçamento da união dos deputados federais do Estado da Paraíba da 53ª legislatura : uso eleitoral das emendas individuais ao orçamento

O presente trabalho consiste na análise das emendas individuais ao Orçamento da União dos deputados federais do Estado da Paraíba, na 53ª legislatura, para verificar se elas atendem as prioridades sociais da população, baseando-se no Índice de Desenvolvimento Humano onde identificamos o índice de pobreza elevado, ou se elas são destinadas mais com intuito de lograr êxito nas campanhas eleitorais. São analisadas também quais as principais áreas que as emendas são destinadas e se há ou não privilégios em sua destinação, de acordo com o colegiado eleitoral dos parlamentares. Para tanto, descrevemos um pouco sobre o Estado e posteriormente apresentamos uma visão geral do orçamento. Conclui-se que fica comprovado o quanto é presente a oligarquia na política do Estado e, por isso, revela as ações paroquialistas dos deputados que utilizam as emendas orçamentárias individuais para levar benefícios para seus redutos eleitorais, bem como para localidades que possam lhe prospectar uma votação significativa e assim garantir sua reeleição ou eleição dos seus indicados.

A atuação do Conselho de Ética nos casos de quebra de decoro parlamentar nas 52ª e 53ª legislaturas

Propõe a avaliação das representações apreciadas pelo Conselho de Ética e Decoro Parlamentar da Câmara dos Deputados da 52ª e 53ª Legislaturas. Com base na análise do conjunto das representações protocoladas entre os anos 2003 a 2011, pretende-se responder se os instrumentos normativos e legais são eficazes no combate à quebra de decoro ou se de alguma forma favorecem a impunidade. Identifica os dispositivos legais que tratam do decoro parlamentar, como o Código de Ética e Decoro Parlamentar da Câmara dos Deputados, a Constituição da República Federativa do Brasil e o Regimento Interno da Câmara dos Deputados. São ainda relacionados alguns processos que resultaram em perda de mandato ou que fixaram normas interpretativas.
