Texas Center for Digital Humanities and New Media

We propose the creation of a Center for Digital Humanities, Media and Culture (formerly titled Texas Center for Digital Humanities and New Media). The Center will address two related grand challenges: the need to investigate the relationship of computing technologies and culture, and the need to construct cyberinfrastructure for the humanities and social sciences. The Center’s research, focused in four interrelated areas -- the cultural record, cultural systems, cultural environments, and cultural interactions in the digital age – engages one of the most compelling questions of our time: What does it mean to be human in the digital age

Alimentación ad libitum y restringida de pollitas Dekalb White® de cero a seis semanas de edad con y sin semolina

13 p.El estudio se realizó entre los meses de mayo y julio del año 2017 en el Centro de Investigación y Enseñanza Avícola de la Escuela Agrícola Panamericana, Honduras. Se utilizaron 2288 pollas Dekalb White® desde el nacimiento hasta las seis semanas de edad, con el objetivo de evaluar dos dietas diferentes (sin y con 5 % de semolina) suministradas ad libitum y de forma restringida, para conocer sus efectos sobre el peso vivo, consumo alimenticio, uniformidad, mortalidad y el costo de la alimentación. Las aves se alojaron en 48 corrales experimentales de 1.50m × 3.75m c/u, a una densidad de ocho pollas por m². Se utilizaron cuatro tratamientos con 12 repeticiones cada uno, distribuidos según Diseño Completamente al Azar (DCA). El consumo de alimento acumulado demostró que las aves alimentadas de forma restringida disminuyeron significativamente su consumo (P≤0.05) independientemente del tipo de dieta suministrada. No se obtuvo diferencias significativas en el peso vivo alcanzado al final de las seis semanas de edad para ninguno de los tratamientos. Todos los pesos sobrepasaron el peso óptimo del híbrido comercial. La uniformidad se mantuvo arriba del 85% a todas las edades y en todos los tratamientos analizados. El suministro de alimento restringido de una dieta con 5% de semolina presentó el costo de alimentación más viable en la crianza de pollitas de remplazo Dekalb White® durante las primeras seis semanas de vida

Drought elicits contrasting responses on the autumn dynamics of wood formation in late successional deciduous tree species

Abstract Research on wood phenology has mainly focused on reactivation of the cambium in spring. In this study we investigated if summer drought advances cessation of wood formation and if it has any influence on wood structure in late successional forest trees of the temperate zone. The end of xylogenesis was monitored between August and November in stands of European beech and pedunculate oak in Belgium for two consecutive years, 2017 and 2018, with the latter year having experienced an exceptional summer drought. Wood formation in oak was affected by the drought, with oak trees ceasing cambial activity and wood maturation about 3 weeks earlier in 2018 compared with 2017. Beech ceased wood formation before oak, but its wood phenology did not differ between years. Furthermore, between the 2 years, no significant difference was found in ring width, percentage of mature fibers in the late season, vessel size and density. In 2018, beech did show thinner fiber walls, whereas oak showed thicker walls. In this paper, we showed that summer drought can have an important impact on late season wood phenology xylem development. This will help to better understand forest ecosystems and improve forest models.</jats:p

In Vitro Susceptibilities of Mycoplasma hyopneumoniae Field Isolates

The in vitro susceptibilities of 21 Mycoplasma hyopneumoniae field isolates were determined using a broth microdilution technique. One isolate showed acquired resistance to lincomycin, tilmicosin, and tylosin, while five isolates were resistant to flumequine and enrofloxacin. Acquired resistance against these antimicrobials in M. hyopneumoniae field isolates was not reported previously
