Fractionation of immunoreactive cholecystokinin by adsorption to QUSO or talc
No full textThe technique of adsorption of peptides containing basic amino acids to surfaces of silica or talc has been extended to distinguish between the basic precursor peptides, cholecystokinin (CCK33) and its variant (CCK39), and their COOH-terminal 12 and 8 amino acid fragments (CCK12 and CCK8) in plasma and tissue extracts. CCK39 and CCK33 are quantitatively adsorbed from 2 ml of solution by 5 mg QUSO G32 or 25 mg talc. The adsorbed basic peptides can be completely eluted from QUSO but not from talc by 0.1N HC1. CCK12 and CCK8 are not detectably adsorbed by either QUSO or talc. The method is simple, inexpensive and is suitable for rapid handling of multiple samples
Effects of obstruent voicing on vowel fundamental frequency in Dutch
No full textIt has been known for a long time and for a wide variety of languages that vowel fundamental frequency (F0) can be affected by the intrinsic properties of the preceding consonants. In particular, F0 following voiceless obstruents tends to be significantly higher than F0 following voiced obstruents (e.g., House and Fairbanks, 1953; Hombert et al., 1979). There has been a long-standing debate about the cause of this phenomenon. Some evidence in previous work is more compatible with a physiological/aerodynamic account of this effect (e.g., Halle and Stevens, 1967; Kirby & Ladd, 2016), while other supports an auditory enhancement account (e.g., Kingston and Diehl 1994). This paper investigates these consonant-related F0 perturbations in Dutch after initial fricatives (/v f/) and stops (/b p/), as compared to after sonorant /m/, in recordings by Pinget (2015). Dutch is particularly interesting for the investigation of F0 perturbations for two reasons: 1) Dutch – unlike English – is a true voicing language and 2) Dutch initial fricatives are currently undergoing a process of devoicing (e.g., Kissine et al., 2003; Pinget, 2015). The F0 contours in isolated words were analyzed using GAMM (e.g., Wieling 2018) with /m/ as baseline condition. Results show that after unvoiced /p, f/, the F0 at vowel onset is significantly higher than this baseline. Moreover, voicing measures (degree of voicing, duration, and VOT) interact with the main effects of onset consonant on F0. Especially after /v/, F0 at vowel onset increased as the voicing measures of preceding /v/ decreased. Thus, we found no trace of an active gesture to explicitly lower F0 after highly devoiced fricatives, as would be predicted by an auditory enhancement account. In conclusion, these results regarding F0 contours, the time course of the effects and the covariation patterns are taken as evidence to support a physiological/aerodynamic cause of F0 perturbations
Evaluación de poblaciones de raigrás anual infectadas y libres de endófitos en dos localidades
No full textPoster y ponencia. Publicado en: Revista Argentina de Producción Animal – RAPA 43 (Supl. 1) : 83. (septiembre 2023)Las EEAs Pergamino y C. del Uruguay del INTA llevan adelante un programa de mejoramiento genético de raigrás anual (Lolium multiflorum Lam), donde uno de los criterios de selección es la adaptabilidad a condiciones ambientales variables. En este contexto, la inclusión de endófitos (E+, Epichlöe occultans) en el germoplasma bajo selección, sería una estrategia innovadora para mejorar esta adaptabilidad. El objetivo de este trabajo fue caracterizar germoplasma (E+/E) en caracteres asociados a la producción en diferentes ambientes de crecimiento.EEA PergaminoFil: Da Silva, L.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
