Advances in Near-surface Seismology and Ground-penetrating Radar

Advances in Near-surface Seismology and Ground-penetrating Radar (SEG Geophysical Developments Series No. 15) is a collection of original papers by renowned and respected authors from around the world. Technologies used in the application of near-surface seismology and ground-penetrating radar have seen significant advances in the last several years. Both methods have benefited from new processing tools, increased computer speeds, and an expanded variety of applications. This book, divided into four sections ? ?Reviews,? ?Methodology,? ?Integrative Approaches,? and ?Case Studies? ? captures the most significant cutting-edge issues in active areas of research, unveiling truly pertinent studies that address fundamental applied problems. This collection of manuscripts grew from a core group of papers presented at a postconvention workshop, ?Advances in Near-surface Seismology and Ground-penetrating Radar,? held during the 2009 SEG Annual Meeting in Houston, Texas. This is the first cooperative publication effort between the near-surface communities of SEG, AGU, and EEGS. It will appeal to a large and diverse audience that includes researchers and practitioners inside and outside the near-surface geophysics community.

2013 Update in addiction medicine for the generalist.

Increasingly, patients with unhealthy alcohol and other drug use are being seen in primary care and other non-specialty addiction settings. Primary care providers are well positioned to screen, assess, and treat patients with alcohol and other drug use because this use, and substance use disorders, may contribute to a host of medical and mental health harms. We sought to identify and examine important recent advances in addiction medicine in the medical literature that have implications for the care of patients in primary care or other generalist settings. To accomplish this aim, we selected articles in the field of addiction medicine, critically appraised and summarized the manuscripts, and highlighted their implications for generalist practice. During an initial review, we identified articles through an electronic Medline search (limited to human studies and in English) using search terms for alcohol and other drugs of abuse published from January 2010 to January 2012. After this initial review, we searched for other literature in web-based or journal resources for potential articles of interest. From the list of articles identified in these initial reviews, each of the six authors independently selected articles for more intensive review and identified the ones they found to have a potential impact on generalist practice. The identified articles were then ranked by the number of authors who selected each article. Through a consensus process over 4 meetings, the authors reached agreement on the articles with implications for practice for generalist clinicians that warranted inclusion for discussion. The authors then grouped the articles into five categories: 1) screening and brief interventions in outpatient settings, 2) identification and management of substance use among inpatients, 3) medical complications of substance use, 4) use of pharmacotherapy for addiction treatment in primary care and its complications, and 5) integration of addiction treatment and medical care. The authors discuss each selected articles' merits, limitations, conclusions, and implication to advancing addiction screening, assessment, and treatment of addiction in generalist physician practice environments.

Who wrote the Second Ave maris stella of Tomás Luis de Victoria?

Contrary to what Felipe Pedrell indicates, the second Ave maris stella in his Victoria's collected works (vol. V, 1908, pp. 100-3, n° 33) doesn't appear in the collection published in 1600 in Madrid by the composer, nor in any other of the musician's books. In the 1600 edition, Victoria reissues the two first verses (plainchant followed by polyphony) of the Ave maris stella published in 1576 and then again in 1581. The earliest source of the problematic Ave maris stella is Munich, Bayerische Staatsbibliothek, Musik-Abteilung, 2 Mus. pr. 23 handschriftlicher Beiband, dating from the third quarter oft he seventeenth century. This source is a manuscrit that runs as an appendix to the 1581 edition of Victoria's hymns. No attributions are given in the manuscript. The first attributions of the piece to Victoria arise in the nineteenth century, in manuscripts copied by Johann Michael Hauber, Johann Caspar Aiblinger, August Baumgartner and Carl Proske, and preserved in Munich and Regensburg. Proske pubished the piece in his Musica divina in 1859 (Annus primus, vol. III, pp. 419-24). The most probable hypothesis ist that Pedrell had knowledge of the second Ave maris stella, under the spanish composer's name, via Proske's Musica divina. In all likelihood the piece is not by Victoria, not least because the composer has never written odd polyphonic verses of hymns. In his Studies in the Music of Tomás Luis de Victoria (2001), Eugene Casjen Cramer relies on the supposed authenticity of the work to ascribe the others pieces of Munich, Bayerische Staatsbibliothek, Musik-Abteilung, 2 Mus. pr. 23 handschriftlicher Beiband to the composer. These attributions should therefore be refuted.

Rigor metodológico e investigación filológica

In recent decades, technological advances have made extensive documentation available to us. But the philologist must be aware of the dangers of poor use of the documentary corpus in order to avoid creating dreaded ghost words. In this paper we recall the main sources of this type of error: folk etymology phenomena among speakers, copyists" errors, transcribers" errors in the interpretation of some abbreviations and graphic variants of the manuscripts, onomastic changes introduced by cartographers" ignorance of linguistic variants, gaps in the dating of some documents, confusion in the processes of lemmatization and the evaluation of texts... All these sources of error contribute, to a greater or lesser degree, to the distortion or to the masking of the data on which the research of philologists is based. Hence the importance of philological rigour in the transmission and study of ancient texts.

Blue light activates a specific protein kinase in higher plants.

Blue light mediates the phosphorylation of a membrane protein in seedlings from several plant species. When crude microsomal membrane proteins from dark-grown pea (Pisum sativum L.), sunflower (Helianthus annuus L.), zucchini (Cucurbita pepo L.), Arabidopsis (Arabidopsis thaliana L.), or tomato (Lycopersicon esculentum L.) stem segments, or from maize (Zea mays L.), barley (Hordeum vulgare L.), oat (Avena sativa L.), wheat (Triticum aestivum L.), or sorghum (Sorghum bicolor L.) coleoptiles are illuminated and incubated in vitro with [gamma-(32)P]ATP, a protein of apparent molecular mass from 114 to 130 kD is rapidly phosphorylated. Hence, this system is probably ubiquitous in higher plants. Solubilized maize membranes exposed to blue light and added to unirradiated solubilized maize membranes show a higher level of phosphorylation of the light-affected protein than irradiated membrane proteins alone, suggesting that an unirradiated substrate is phosphorylated by a light-activated kinase. This finding is further demonstrated with membrane proteins from two different species, where the phosphorylated proteins are of different sizes and, hence, unambiguously distinguishable on gel electrophoresis. When solubilized membrane proteins from one species are irradiated and added to unirradiated membrane proteins from another species, the unirradiated protein becomes phosphorylated. These experiments indicate that the irradiated fraction can store the light signal for subsequent phosphorylation in the dark. They also support the hypothesis that light activates a specific kinase and that the systems share a close functional homology among different higher plants.

White under Black. Works from the imperceptible / 1. Blanca Casas Brullet: Make Say The large photographs of Espacespages (2009) work to transform the creative space of the blank page toward the enabled space of openness to the world. The image gives prominence to the emptiness of the room, almost a cell, in which an action takes place, dimly illuminated by a pair of windows that makes me think of two eyes that attentively contemplate the interior of a process of creation.

Enhanced-reality video fluorescence: a real-time assessment of intestinal viability.

OBJECTIVE: Our aim was to evaluate a fluorescence-based enhanced-reality system to assess intestinal viability in a laparoscopic mesenteric ischemia model. MATERIALS AND METHODS: A small bowel loop was exposed, and 3 to 4 mesenteric vessels were clipped in 6 pigs. Indocyanine green (ICG) was administered intravenously 15 minutes later. The bowel was illuminated with an incoherent light source laparoscope (D-light-P, KarlStorz). The ICG fluorescence signal was analyzed with Ad Hoc imaging software (VR-RENDER), which provides a digital perfusion cartography that was superimposed to the intraoperative laparoscopic image [augmented reality (AR) synthesis]. Five regions of interest (ROIs) were marked under AR guidance (1, 2a-2b, 3a-3b corresponding to the ischemic, marginal, and vascularized zones, respectively). One hour later, capillary blood samples were obtained by puncturing the bowel serosa at the identified ROIs and lactates were measured using the EDGE analyzer. A surgical biopsy of each intestinal ROI was sent for mitochondrial respiratory rate assessment and for metabolites quantification. RESULTS: Mean capillary lactate levels were 3.98 (SD = 1.91) versus 1.05 (SD = 0.46) versus 0.74 (SD = 0.34) mmol/L at ROI 1 versus 2a-2b (P = 0.0001) versus 3a-3b (P = 0.0001), respectively. Mean maximal mitochondrial respiratory rate was 104.4 (±21.58) pmolO2/second/mg at the ROI 1 versus 191.1 ± 14.48 (2b, P = 0.03) versus 180.4 ± 16.71 (3a, P = 0.02) versus 199.2 ± 25.21 (3b, P = 0.02). Alanine, choline, ethanolamine, glucose, lactate, myoinositol, phosphocholine, sylloinositol, and valine showed statistically significant different concentrations between ischemic and nonischemic segments. CONCLUSIONS: Fluorescence-based AR may effectively detect the boundary between the ischemic and the vascularized zones in this experimental model.
