Frações de fósforo no solo de vinhedo na Serra Gaúcha do Rio Grande do Sul R E S U M O Objetivou-se, com este trabalho, avaliar o acúmulo de frações de P no perfil de um solo de vinhedo com aplicações sucessivas de fertilizantes fosfatados. Em janeiro de 2010 foram selecionados, em Bento Gonçalves, RS, uma área de mata nativa e um vinhedo com 33 anos de idade e com histórico de aplicação de fer...

This paper studies implementations of concurrent objects that exploit the absence of step contention. These implementations use only reads and writes when a process is running solo. The other processes might be busy with other objects, swapped-out, failed, or simply delayed by a contention manager. We study in this paper two classes of such implementations, according to how they handle the case...

The importance of collaboration in research is widely accepted, as is the fact that articles with more authors tend to be more cited. Nevertheless, although previous studies have investigated whether the apparent advantage of collaboration varies by country, discipline, and number of co-authors, this study introduces a more fine-grained method to identify differences: the geometric Mean Normali...

Falling Up is an evening-length performance incorporating dance and theatre with movement-controlled audio/video playback and processing. The solo show is a collaboration between Cindy Cummings (performance) and Todd Winkler (sound, video), first performed at the Dublin Fringe Festival, 2001. Each thematic section of the work shows a different type of interactive relationship between movement, ...

unfortunate developments such as a reduction in creativity, a move to a consideration of the potential personal and paralysis of scientifIC interaction, a decline in the integration of scientific costs of the multiple-experiment paper. the field, and an emPhasis on miavcertainty at the expense of examination of broad possibilities. The paper that reports a solo BUMBLERS AND POINfERS experiment ...

This article is concerned with the F0 tracking in monodic instrument solo recordings. Due to reverberation, the observed signal is rather polyphonic and single-F0 tracking techniques often give unpromising results. The proposed method is based on multiple-F0 estimation and makes use of the a priori knowledge that the observed spectrum is generated by a single monodic instrument. The predominant...

Objectives. To describe the health characteristics of solo grandparents raising grandchildren compared with single parents. Methods. Using the 2012 Behavioral Risk Factor Surveillance System, respondents identified as a single grandparent raising a grandchild were categorized as a solo grandparent; grandparent responses were compared with single parents. Descriptive analysis compared health cha...

Sister chromatid cohesion is essential to maintain stable connections between homologues and sister chromatids during meiosis and to establish correct centromere orientation patterns on the meiosis I and II spindles. However, the meiotic cohesion apparatus in Drosophila melanogaster remains largely uncharacterized. We describe a novel protein, sisters on the loose (SOLO), which is essential for...

The purpose of this study was to examine the effect of the presence of a music stand and performer’s eye contact on high school solo vocal performance quality ratings. Undergraduate music and non-music majors (N = 167) assigned ratings to three audiovisual recordings: memorized, non-memorized with eye contact to audience, and non-memorized without eye contact to audience. Significantly higher r...
