Copyright de la memoria, autoficción y novela familiar en 'Soy un bravo piloto de la nueva China'
Authors: Blejmar Jordana 
Published: June 2014

Resumen: Soy un bravo piloto de la nueva China (Semán, 2011) supone una vuelta de tuerca en la representación de la última dictadura militar argentina propuesta por la literatura autoficcional de las generaciones de la postdictadura. Si bien es cierto que existen antecedentes de novelas sobre la dictadura (notables, por cierto) en las que la focalización está puesta del lado de los militares o de sus cómplices, por primera vez es una víctima directa de la dictadura el que le otorga, en la ficción, esa posición de testigo de la historia a un perpetrador. La apuesta fuerte y valiente de Semán descansa en la sospecha de que para entender mejor la historia familiar y nacional, no alcanza con los documentos heredados (cartas y fotos), o con los recuerdos de los que habitan el mundo de los vivos. La autoficción y la literatura le ofrecen lo que no puede el testimonio, la autobiografía o la crónica histórica.Abstract: Soy un bravo piloto de la nueva China (Semán, 2011) marks a shift in the autofictional representation of the last Argentine dictatorship. Like writers from previous generations and also other children of disappeared parents who have written fictional accounts of the period, Semán also grapples with the problem of how to represent perpetrators by including a military officer as a principal character. This novel, however, represents the first time that a direct victim of the dictatorship – Semán’s father being disappeared by the military regime – includes, as part of the narrative, the point of view of the perpetrator to bear witness to the traumatic events of recent Argentine history.

Correlation between groundwater flow and deformation in the fractured carbonate Gran Sasso aquifer (INFN underground laboratories, central Italy)
Authors: Amoruso A. , Crescentini L. , Martino S. , Petitta M. , Tallini M. 
Published: June 2014

AbstractThe Gran Sasso massif is a carbonate fractured aquifer with a spring discharge of more than 18 m3 s−1. The water table has been partially drained by two motorway tunnels and an underground laboratory (UL), located into the core aquifer. Karst features have limited role below the water table, where groundwater flow is mainly regulated by the fracture network. Two paired laser extensometers (BA and BC) recorded ground deformation in the UL. Changes in deformation correlate with the seasonal recharge/discharge cycle of groundwater flow and its long‐term changes. Hydrostatic conditions prevail during the recharge phases because of the low permeability of local fractures, favoring compression, and hydraulic gradient increase above the UL. Fast groundwater flow through the high‐permeability fault outcropping in the UL can enhance local dilatation for short periods. Spring discharge during exhaustion periods is fed by the low‐permeability fracture network, fostering hydrodynamic conditions by hydraulic gradient decrease, diminishing compression and consequently favoring dilatation. Independent support to this conceptual model comes from local tests and a numerical model which highlights the hydromechanical strain effects induced by the hydrological cycle on the jointed rock mass along BA and the role of the hydraulic gradient on the rock mass deformation.
A dynamical system perspective on plant hydraulic failure
Authors: Manzoni Stefano , Katul Gabriel , Porporato Amilcare 
Published: June 2014

AbstractPhotosynthesis is governed by leaf water status that depends on the difference between the rates of transpiration and water supply from the soil and through the plant xylem. When transpiration increases compared to water supply, the leaf water potential reaches a more negative equilibrium, leading to water stress. Both high atmospheric vapor pressure deficit and low soil moisture increase the water demand while decreasing the supply due to lowered soil‐to‐root conductance and xylem cavitation. Therefore, dry conditions may eventually reduce the leaf water potential to the point of collapsing the plant hydraulic system. This “hydraulic failure” is shown to correspond to a fold bifurcation where the environmental parameters (vapor pressure deficit and soil moisture) trigger the loss of a physiologically sustainable equilibrium. Using a minimal plant hydraulic model, coordination among plant hydraulic traits is shown to result in increased resilience to environmental stresses, thereby impeding hydraulic failure unless hydraulic traits deteriorate due to prolonged water shortage or other damages.
Detecting fossil fuel emissions patterns from subcontinental regions using North American in situ CO2 measurements

AbstractThe ability to monitor fossil fuel carbon dioxide (FFCO2) emissions from subcontinental regions using atmospheric CO2 observations remains an important but unrealized goal. Here we explore a necessary but not sufficient component of this goal, namely, the basic question of the detectability of FFCO2 emissions from subcontinental regions. Detectability is evaluated by examining the degree to which FFCO2 emissions patterns from specific regions are needed to explain the variability observed in high‐frequency atmospheric CO2 observations. Analyses using a CO2 monitoring network of 35 continuous measurement towers over North America show that FFCO2 emissions are difficult to detect during nonwinter months. We find that the compounding effects of the seasonality of atmospheric transport patterns and the biospheric CO2 flux signal dramatically hamper the detectability of FFCO2 emissions. Results from several synthetic data case studies highlight the need for advancements in data coverage and transport model accuracy if the goal of atmospheric measurement‐based FFCO2 emissions detection and estimation is to be achieved beyond urban scales.
An improved model for calculating tropospheric wet delay
Authors: Dousa Jan , Elias Michal 
Published: June 2014

AbstractA new concept is described for calculating the tropospheric zenith wet delay (ZWD) and its vertical approximation derived from the original profile of meteorological data. A new parameter of ZWD exponential decay is introduced which, together with a reference value, represents ZWD corrections accurately up to 10 km altitude. The new parameter considerably improves ZWD vertical reduction and surface ZWD calculation using the model of Askne and Nordius (1987). This development reduces the original large data set of a numerical weather model to an accurate grid representation at a reference level that may be more effectively disseminated. This can be used in regional augmentation models for precise positioning and navigation.
Magnitude −7 level earthquakes: A new lower limit of self‐similarity in seismic scaling relationships
Authors: Yoshimitsu Nana , Kawakata Hironori , Takahashi Naoki 
Published: June 2014

AbstractMicrofractures occurring in a rock sample that are called acoustic emission (AE) events show some similar features to earthquakes. However, it remains to be shown whether or not AE equate to ultramicroearthquakes. In this study, we show the existence of magnitude −7 level earthquakes based on seismological analyses of AE source parameters. Advances in multichannel, broadband, high‐speed continuous recording of AE under seismogenic pressure conditions has facilitated increasingly robust measurement. Source parameters of AE show that AE events satisfy the same scaling relationship as natural earthquakes in which seismic moment is inversely proportional to the cube of corner frequency. This result suggests that both millimeter scale fractures and natural earthquakes of kilometer scale ruptures are highly similar as physical processes. Hence, AE events can be interpreted as ultramicroearthquakes having a magnitude of about −7. These results demonstrate that laboratory observation is an effective approach in studying natural earthquake generation process.

Published: June 2014

AbstractAcoustic, VHF, and electrostatic measurements throw new light onto the origin and production mechanism of the thunder infrasound signature (<10 Hz) from lightning. This signature, composed of an initial compression followed by a rarefaction pulse, has been the subject of several unconfirmed theories and models. The observations of two intracloud flashes which each produced multiple infrasound pulses were analyzed for this work. Once the variation of the speed of sound with temperature is taken into account, both the compression and rarefaction portions of the infrasound pulses are found to originate very near lightning channels mapped by the Lightning Mapping Array. We found that none of the currently proposed models can explain infrasound generation by lightning, and thus propose an alternate theory: The infrasound compression pulse is produced by electrostatic interaction of the charge deposited on the channel and in the streamer zone of the lightning channel.

AbstractThe Geostationary Ocean Color Imager (GOCI) can be utilized efficiently to observe subtle changes in oceanic environments under cloud‐free conditions because it receives ocean color images around the Korean Peninsula hourly, for 8 h a day. Here we investigated the applicability of the GOCI for estimating hourly variations in ocean surface currents, which provide significant information on seawater circulation for fisheries, shipping controls, and more. Ocean surface currents were deduced from eight images of GOCI‐derived total suspended matter (TSM) from highly turbid coastal waters and images of chlorophyll concentration (CHL) for relatively clear waters. The results showed that GOCI TSM‐derived ocean surface currents can effectively estimate and represent fast tidal currents, as well as flood and ebb tides on the west coast of Korea, in comparison with in situ measurements. GOCI‐derived CHL scenes successfully illustrated currents moving along boundaries where warm and cold seawaters mix, in addition to mesoscale currents such as the East Korea Warm Current (EKWC) in the East Sea of Korea. Satellite‐based sea surface temperature and sea surface height images supported the reliability of GOCI‐derived ocean surface currents in the East Sea.
CC Coupling Through Intramolecular Dual CH Activation Directed by a Removable Carboxylate Group: A Method for the Synthesis of Fluorenones under Mild Reaction Conditions
Authors: Liu Lu , Wang Fang , Li Zhenghong , Wang Jianhui 
Published: June 2014

AbstractA highly efficient method for the synthesis of fluorenones through a palladium‐catalyzed intramolecular oxidative coupling reaction via dual CH activations is reported. In this reaction, substituted fluorenones were obtained in moderate to high yields from diphenylacetic acid and its derivatives as substrates. The carboxylate, as a removable directing group, plays an important role in the dual CH activations of the substrate. The current method provides an efficient synthetic route for producing a variety of substituted fluorenones under mild reaction conditions.
The effect of depth and duration of UV radiation on polypropylene modification via photoinitiation
Authors: Amintowlieh Yasaman , Tzoganakis Costas , Penlidis Alexander 
Published: June 2014

ABSTRACTLinear polypropylene (PP) was modified using UV radiation in the presence of 0.5 wt % of benzophenone photoinitiator to introduce long chain branching (LCB) to the PP backbone. Irradiation was carried out in the solid state and the temperature level was kept below 60°C. The effects of radiation duration and sample thickness on the extent of these branching modification reactions were investigated. Viscoelastic properties, molecular weight, molecular weight distribution, and gel content were determined and compared for runs having different sample thicknesses, irradiated for different times. Comparisons were also conducted with the parent PP and the PP mixed with photoinitiator. It was found that LCB decreased by increasing the thickness of the samples. Conversely, an increase in radiation duration resulted in enhanced LCB but also led to larger gel content in the samples. Based on all these measurements and observations, a mechanism was suggested to explain formation of long chain branches (LCBs) in PP in the solid state via photoinitiation. © 2014 Wiley Periodicals, Inc.

Nondestructive, Epi‐Illumination Surface Microscopic Characterization of Surface Discontinuity in Bone: A New Approach Offers a Descriptive Vocabulary and New Insights
Authors: Rothschild Bruce M. 
Published: June 2014

ABSTRACTPerspectives are in the eye of the beholder and are expanded with increased scrutiny (e.g., magnification). The term “porosity' for macroscopically or radiologically identifiable discontinuity in bone is so variably applied as to be incomprehensible in its meanings. A closer examination of surface discontinuity seems appropriate. Histological and atomic level analysis of bone alterations misses the forest for the trees and the former destroys the very subject it attempts to characterize. Surface discontinuity was therefore evaluated at the three‐dimensional submacroscopic level. An epifluorescent/illumination microscope was used to characterize surface discontinuity in intact specimens of known pathophysiology and/or derivation. The derived perspectives were then utilized to characterize other surface discontinuity. The smooth boundaries of vascular foramen and internal bifurcation, continuity of the expanded base of nerve structures and surrounding elevated rings of Sharpey fibers are all clearly distinguishable from fronts of resorption in erosive arthritis, serpentine discontinuity associated with infectious processes, specific zones of resorption noted in tuberculosis, and structural bone exposure by taphonomic abrasion. These perspectives allow the bone pathology associated with hematoma to be characterized as accentuated Sharpey fiber insertions; maxillary and sphenoid surface discontinuity, as vascular in origin; and periosteal reaction, as manifest by superficial bifurcating channels and in‐growth, similar to healing trephanation. Epi‐illumination microscopy bridges macroscopic and histological examination, providing greater understanding of the pathology, at no cost to the integrity of the material studied. It explains a number of observed results, while providing discriminatory descriptions of phenomena for which pathophysiology has not yet been clarified.

Morphology and Variation in Porpoise (Cetacea: Phocoenidae) Cranial Endocasts
Authors: Racicot Rachel A. , Colbert Matthew W. 
Published: June 2014

ABSTRACTEvolution of endocranial anatomy in cetaceans is important from the perspective of echolocation ability, intelligence, social structure, and alternate pathways for circulation to the brain. Apart from the importance of studying brain shape and asymmetries as they relate to aspects of behavior and intelligence, cranial endocasts can show a close correspondence to the hydrostatic shape of the brain in life, and canals and grooves can preserve features of the circulatory system. Multiple samples are rarely available for studies of individual variation, especially in fossils, thus a first step in quantifying variation and making comparisons with fossils is made possible with CT scans of osteological specimens. This study presents a series of high‐resolution X‐ray CT‐derived cranial endocasts of six extant species of Phocoenidae, a clade including some of the smallest and one of the rarest cetaceans. Degree of gyrification varies interspecifically and intraspecifically, possibly resulting from variation in preservation of the ossified meninges. Computed tomographic data show that visually assessed asymmetry in the cranial endocasts is not correlated with volumetric measurements, but nonetheless may reflect torsion in the skull's shape such that the right cerebral and cerebellar hemispheres extend rostrally and laterally more than the left. Vasculature and canals are similar to other described cetacean species, but the hypophyseal casts are unusual. Similarities between brain shape and volume measurements in the different species can be attributed to paedomorphism and concomitant variation in ecological preferences. This may explain similarities Neophocaena phocaenoides and Phocoena sinus share with the juvenile Phocoena phocoena specimen studied. Anat Rec, 296:979–992, 2013. © 2013 Wiley Periodicals, Inc.
Ontogeny of the Vertebral Column of Eleutherodactylus johnstonei (Anura: Eleutherodactylidae) Reveals Heterochronies Relative to Metamorphic Frogs

Published: June 2014

ABSTRACTOver the last century, the morphogenesis of the vertebral column has been considered as a highly conserved process among anurans. This statement is based on the study of few metamorphic taxa, ignoring the role of developmental mechanisms underlying the evolution of specialized life‐histories. Direct development in anurans has been regarded as evolutionarily derived and involves developmental recapitulation and repatterning at different levels in all amphibian taxa studied so far. Herein, we analyze the vertebral column morphogenesis of the direct‐developing frog Eleutherodactylus johnstonei, describing the sequence of chondrification and ossification, based on cleared and double‐stained specimens from early stage embryos to adults. In general, our results show that the morphogenesis of the vertebral column in E. johnstonei recapitulates the ancestral tadpole‐like pattern of development. However, the analysis of the sequence of events using heterochrony plots shows important heterocronies relative to metamorphic species, such as a delay in the chondrification of the vertebral centra and in osteogenesis. These ontogenetic peculiarities may represent derived traits in direct‐developing frogs and are possibly correlated with its unusual life history. In addition, several features of the vertebral column of E. johnstonei are highly variable from its typical morphology. We report some malformations and small deviations, which do not seem to affect the survival of individuals. These anomalies have also been found in other frogs, and include many vertebral defects, such as vertebral fusion, and vertebral preclusion and/or induction.

Published: June 2014

ABSTRACTAnimals living in nontropical climates modify their physiology and behavior to adapt to seasonal environmental changes. Part of this adaptation involves the release of catecholamine from sympathetic nerve endings and the adrenal medulla, which play a major role in regulating energy balance. The aim of this work was to investigate whether adult male viscachas in their natural habitat exhibits structural changes in the adrenal medulla during the annual seasonal cycle. In August–September, chromaffin granules revealed ultrastructural changes suggestive of piecemeal degranulation. Quantitative morphometric analysis by transmission electron microscopy showed a significantly lower percentage of resting chromaffin granules and a higher percentage of altered granules and empty containers in August–September (late winter) compared to February–March (late summer), suggesting an increased secretory process of catecholamines in August–September. The mechanism of piecemeal degranulation might amplify this process, encouraging the adaptive response to winter environmental conditions. Tissue levels of epinephrine, norepinephrine, and dopamine (analyzed by high‐performance liquid chromatography) changed throughout the year, reaching maximum values in February–March and minimum values in August–September. These results demonstrate morphological and biochemical seasonal variations of the adrenal medulla, suggesting that epinephrine might promote energy mobilization, which allow the Lagostomus to cope with adverse environmental conditions and thus to survive during winter season.
