Robert Gerhard i l’avantguarda musical. Contribucions de Robert Gerhard a la música contemporània a Barcelona del 1929 al 1938

Treballs Finals de Grau d'Història de l'Art, Facultat de Geografia i Història, Universitat de Barcelona, Curs: 2013-2014, Tutor: Xosé AviñoaEl present treball té com a objecte d’estudi les contribucions de Robert Gerhard a la música contemporània a Barcelona durant el 1929 i el 1938. L’elecció d’aquest tema ve donada per un interès personal en l’art d’avantguarda i, concretament, en els compositors de la primera meitat del segle XX. El període en el qual em centro coincideix amb l’any en que Gerhard tornà a Barcelona després de completar la seva formació com a compositor amb Schönberg, l’any 1929, i fins al seu exili, el 1938. A més a més, es tracta d’un període emmarcat per esdeveniments socials que són de gran interès: la Dictadura de Primo de Rivera; l’Exposició Internacional de Barcelona del 1929; la Segona República i la Guerra Civil Espanyola

Long-term acute infections during a bovine viral diarrhea virus (BVDV) outbreak in dairy farm from Galicia (NW Spain)

An observational study describes an outbreak of bovine viral diarrhea virus (BVDV) in a dairy herd in Spain. The herd was subjected to a voluntary control program. In a sampling carried out in June 2020, bulk tank milk antibody levels increased compared to the previous sampling. Additionally, serum samples from 4 young heifers also tested positive for antibodies. Since the results were consistent with a recent infection, we proceeded to detect possible persistently infected (PI) animals using antigen ELISA (on serum/ear-notch samples), following the program guidelines. From this moment on, 42 animals tested positive for BVDV antigen, of which 17 were under typical acute infection (AI), 13 were deemed as PI, and eight died early on the farm before having information to determine their status. The remaining 4 showed intriguing test results consistent with a long-term AI since they tested BVDV positive in at least two antigen tests more than 3 weeks apart. Thus, one animal was positive until 80 days of age in serum, and others even for longer periods in ear-notch samples, until they finally tested negative for BVDV. Based on these results, longer follow-up may be necessary in BVDV positive animals to accurately confirm persistent infectionS

El movimiento estudiantil chileno : análisis de las demandas de los estudiantes y del impacto político de las movilizaciones

Conté: Treball de recerca i pòsterDurante la última década la sociedad chilena ha visto el resurgir de una juventud que, a priori considerada apática a la política, y contra todo pronóstico, tomó las calles en diferentes olas de protestas. Se trata de la "Revolución Pingüina" y el "Invierno Chileno", ocurridas en 2006 y 2011, respectivamente. El siguiente trabajo pretende entender cuáles son las demandas de dichas movilizaciones, haciendo hincapié en la necesidad de comprender primero el funcionamiento de un sistema educativo chileno en que la equidad y la calidad brillan por su ausencia. Asimismo, la finalidad última es comprobar en qué grado, y de qué tipo, ha sido el impacto político del movimiento estudiantilDurant la passada dècada la societat xilena ha vist el ressorgir d'una joventut que, considerada apàtica a la política, i contra tot pronòstic, va prendre els carrers en diverses onades de protestes. Es tracta de la "Revolució Pingüina" i de "l'Ivern Xilè", que van tenir lloc el 2006 i 2011, respectivament. El següent treball pretén entendre quines són les demandes d'aquestes mobilitzacions, fent èmfasi en la necessitat de comprendre primer el funcionament d'un sistema educatiu xilè en què l'equitat i la qualitat brillen per la seva absència. Així mateix, la finalitat última es comprovar en quin grau, i de quin tipus, ha estat l'impacte polític del moviment estudianti

Nitrogen Fertilization and Harvest Management Improve Forage and Crude Protein Content in Crabgrass

Crabgrass (Digitaria spp.) is an annual summer grass that can provide high-quality forage, but optimal management strategies are unclear. Our objective was to compare the yield and quality of crabgrass (Mojo and Quick-N-Big) under different nitrogen rates and harvest management. The experimental design was a randomized complete block with five treatments and three replications for each crabgrass variety, totaling fifteen experimental units for both Mojo and Quick-N-Big, in adjacent sites. Treatments were nitrogen rates (0, 100, and 200 lb N/acre) and harvest management (cut once or twice per year) for two growing seasons (2020 and 2021). Total forage accumulation (TFA) increased with nitrogen fertilization for both cultivars. Mojo had the highest TFA in the first year (7000 lb DM/a/yr) while Quick-N-Big TFA was the highest in the second year (7635 lb DM/a/yr). The highest crude protein (CP) content was obtained with the highest N dose, ranging from 10.5 to 13% for both cultivars. Based on these results, N fertilization and harvest management can contribute to improving forage yield and crude protein of crabgrass varieties during the growing season in forage systems

Differential neurophysiological correlates of retrieval of consolidated and reconsolidated memories in humans: An ERP and pupillometry study

Consolidated memories can return to a labile state if they are reactivated by unpredictable reminders. To persist, active memories must be re-stabilized through a process known as reconsolidation. Although there is consistent behavioral evidence about this process in humans, the retrieval process of reconsolidated memories remains poorly understood. In this context, one fundamental question is whether the same or different neurophysiological mechanisms are involved in retrieval of consolidated and reconsolidated memories. Because it has been demonstrated that the exposure to the reconsolidation process may restructure and strengthen memories, we hypothesized distinct neurophysiological patterns during retrieval of reconsolidated memories. In addition, we hypothesized that interfering with the reconsolidation process using a new learning can prevent these neurophysiological changes. To test it, consolidated, reconsolidated and declarative memories whose reconsolidation process was interfered (i.e., picture-word pairs) were evaluated in humans in an old/new associative recall task while the brain activity and the pupillary response were recorded using electroencephalography and eyetracking. Our results showed that retrieval of reconsolidated memories elicits specific patterns of brain activation, characterized by an earlier peak latency and a smaller magnitude of the left parietal ERP old/new effect compared to memories that were only consolidated or whose reconsolidation process was interfered by a new learning. Moreover, our results demonstrated that only retrieval of reconsolidated memories is associated with a late reversed mid-frontal effect in a 600–690 time window. Complementarily, memories that were reactivated showed an earlier peak latency of the pupil old/new effect compared to non-reactivated memories. These findings support the idea that reconsolidation has an important impact in how memories are retrieved in the future, showing that retrieval of reconsolidated memories is partially supported by specific brain mechanisms.Fil: Campos Arteaga, G..

The wideband backend at the MDSCC in Robledo. A new facility for radio astronomy at Q- and K- bands

The antennas of NASA's Madrid Deep Space Communications Complex (MDSCC) in Robledo de Chavela are available as single-dish radio astronomical facilities during a significant percentage of their operational time. Current instrumentation includes two antennas of 70 and 34 m in diameter, equipped with dual-polarization receivers in K (18 - 26 GHz) and Q (38 - 50 GHz) bands, respectively. We have developed and built a new wideband backend for the Robledo antennas, with the objectives (1) to optimize the available time and enhance the efficiency of radio astronomy in MDSCC; and (2) to tackle new scientific cases impossible to that were investigated with the old, narrow-band autocorrelator. The backend consists of an IF processor, a FFT spectrometer (FFTS), and the software that interfaces and manages the events among the observing program, antenna control, the IF processor, the FFTS operation, and data recording. The whole system was end-to-end assembled in August 2011, at the start of commissioning activities, and the results are reported in this paper. Frequency tunings and line intensities are stable over hours, even when using different synthesizers and IF channels; no aliasing effects have been measured, and the rejection of the image sideband was characterized. The first setup provides 1.5 GHz of instantaneous bandwidth in a single polarization, using 8192 channels and a frequency resolution of 212 kHz; upgrades under way include a second FFTS card, and two high-resolution cores providing 100 MHz and 500 MHz of bandwidth, and 16384 channels. These upgrades will permit simultaneous observations of the two polarizations with instantaneous bandwidths from 100 MHz to 3 GHz, and spectral resolutions from 7 to 212 kHz.Comment: 9 pages, 8 figures.
