Última Caracterización morfológica y agronómica de once híbridos de Brachiaria ssp Colegio de Postgraduados Peralta Nava, Jorge Armando. La presente investigación se realizó en dos etapas para caracterizar y evaluar a once híbridos de Brachiaria spp. En la primera etapa se evaluó la producción y calidad de semilla en campo y laboratorio. En campo se utilizó un diseño de bloques al azar evaluándose el rendimiento de semilla ventilada (RDSV) y la densidad de tallos florales (DTF). Los híbridos LNN45 y HBA-69 obtuvieron los mayores RDSV (218.02 y 207.33 kg ha-1 respectivamente). En DTF los mejores híbridos fueron, HBA- 43 y HBA-73 (695 y 606.50 DTF/m2). No hubo una asociación entre RDSV y DTF, lo que hace del llenado de grano un atributo variable en este género. En laboratorio, se evaluó la semilla cosechada por método sudado (MCS) y método manual (MCM), en un diseño completamente...

Ano: 2009 URL: http://hdl.handle.net/10521/1255 Less Discussed Dynamics in the Czech Farm Structure Development AgEcon Curtiss, Jarmila; Ratinger, Tomas; Medonos, Tomas. The paper provides an empirical study of the dynamics of ownership changes in Czech agricultural companies, which are assigned by unique heterogeneity in ownership forms. Since employee ownership has retained a relatively important place in these structures, neoclassical, as well as institutional theories of labour managed firms are considered. Building upon efficiency arguments, both approaches suggest the dissolution of labour managed firms. The empirical analysis utilized detailed survey data from 2004 and accountancy data from 1997 to 2003. We used cluster analysis to classify companies into homogeneous groups with respect to their ownership structure and stage of restructuring, and analysed these characteristics in relation to performance indicators....

Ano: 2006 URL: http://purl.umn.edu/25337 Surfaces in E³ invariant under a one parameter group of isometries of E³ Anais da ABC (AABC) ROUSSOS,IOANNIS M.. We develop a convenient surface theory in E³ in order to apply it to the class of the surfaces invariant under a one-parameter group of isometries of E³. In this way we derive intrinsic characterizations along with several results of subclasses of this class of surfaces that satisfy certain preassigned properties. In the process all results are also effortlessly derived. Among these subclasses are those with surfaces; of constant mean curvature, of constant Gaussian curvature, isothermic, with constant difference or ratio of the principal curvatures.
