Hydrochemical characteristics of throughfall and stemflow in a Moso‐bamboo (Phyllostachys pubescens) forest
Authors: Chiwa Masaaki , Onozawa Yuka , Otsuki Kyoichi 
Published: June 2010

AbstractTo investigate the impacts of the invasion by bamboo on fluxes of nutrients and pollutants, the nutrient/pollutant fluxes and canopy interactions, including neutralization of acidity, leaching and uptake of nitrogen (N), were characterized in conjunction with rainfall partitioning in a Moso‐bamboo (Phyllostachys pubescens) forest. Measurements of precipitation volume, pH, major ions, and silicate (SiO2) in rainfall, throughfall and stemflow were collected weekly in a Moso‐bamboo forest located in Munakata City, Western Japan for 1 year. Results showed that rainfall partitioning into stemflow was larger than that for other types of forest, which may be due to the properties of Moso‐bamboo forest structure, such as a straight and smooth culm. Inorganic N (NO3−+ NH4+) and S (SO42−) fluxes of throughfall and stemflow were approximately 1·6 and 1·3 times higher than that of rainfall, respectively. Contribution of stemflow flux to inorganic N and S fluxes to the forest floor was high. This could be due to lower uptake of inorganic N through culm and a higher rainfall partitioning into stemflow than that for other types of forest. The Moso‐bamboo canopy neutralized rainfall acidity, reducing the fluxes of potentially acidifying compounds via throughfall and stemflow. Canopy leaching of K+was distinctly higher than that of Mg2+and Ca2+and could be related to the high mobility of K+in plant tissues. Cl−and SiO2were readily leached as for K+. The impact of the invasion by bamboo on nutrient cycling was discussed. Copyright © 2010 John Wiley & Sons, Ltd.
Epikarst hydrology and implications for stalagmite capture of climate changes at Grotta di Ernesto (NE Italy): results from long‐term monitoring
Authors: Miorandi Renza , Borsato Andrea , Frisia Silvia , Fairchild Ian J. , Richter Detlev K. 
Published: June 2010

AbstractGrotta di Ernesto is a cave site well suited for palaeoclimate studies because it contains annually laminated stalagmites and was monitored from 1995 to the end of 2008 for microclimate, hydrology and hydrochemistry. Long‐term monitoring highlighted that cave drips show three different hydrological responses to rainfall and infiltration: (1) fast seasonal drips in the upper part of the cave, which are mostly fed by fractures, (2) slow seasonal drips, located at mid‐depth in the cave characterized by mixed feeding and (3) slow drips, mostly located in the deeper gallery, which are fed by seepage flow from bulk porosity with a minor fracture‐fed component. The slow drips display daily cycles during spring thaw. Monitoring also indicated that drip waters are only slightly modified by degassing within the soil zone and aquifer and by prior calcite precipitation. Hydrochemical studies show a clear seasonality in calcite saturation index, which results in most cave calcite precipitation occurring during late autumn and winter with similar amounts of precipitated calcite on most stalagmites, regardless of drip rate (discharge) differences. Drip rate, and drip rate variability, therefore, has a minor role in modulating the amount of annual calcite formation. In contrast, drip rate, when associated with moderate reduction in calcite saturation index, clearly influences stalagmite morphology. Increasing drip rate yields a passage from candle‐, to cone‐ to dome‐shaped stalagmites. Very high drip rates feed speleothems with flowstone morphology. In summary, monitoring provides information about the karst aquifer and how hydrology influences those physical and chemical characteristics of speleothems which are commonly used as climate proxies.

A comparison of stream water temperature regimes from open and afforested moorland, Yorkshire Dales, northern England
Authors: Brown L. E. , Cooper L. , Holden J. , Ramchunder S. J. 
Published: June 2010

AbstractDespite the known importance of water temperature for river ecosystems, the thermal regime of streams and rivers can be heavily modified by afforestation. Although the nature of the heat budget affecting streams in forested catchments shows high variability in space and time, most of the studies of stream temperature response to afforestation have lacked replication among streams. This study examined the impacts of coniferous forest plantations on stream water temperature at six sites (three forested and three open moorland) in the Yorkshire Dales, northern England. Our aim was to test the hypothesis that afforestation would alter the thermal regime of streams, leading to reduced year‐round thermal variability, and cooler summer/warmer winter water temperatures, relative to streams flowing across open moorland. Data collected from April 2007 to March 2009 showed similar thermal dynamics among all six streams over the study period, although variability in forested streams was markedly lower as expected. Mean and maximum daily water temperatures were significantly higher in open moorland streams for much of the year but while some forested streams were warmer than individual moorland streams during winter months (November to February), there was considerable overlap in water temperature between moorland and forest streams. Most stream temperature records showed evidence of low/no winter flow and freezing. These results contrast with many previous studies that have reported warmer temperatures in forested versus open moorland streams during winter, a finding that most likely reflects site‐specific hydrological, geomorphological and climatological influences on water temperature in addition to afforestation. This study demonstrates the need for replication of hydrological monitoring when examining the effects of basin‐scale management practices and provides further evidence for changes in stream thermal regime following afforestation, a practice that is likely to increase in future due to growing demands for increased forest cover in the UK uplands.

AbstractStatistical models predicting cancer recurrence after surgery are based on biologic variables. We have shown previously that prostate cancer recurrence is related to both tumor biology and to surgical technique. Here, we evaluate the association between several biological predictors and biochemical recurrence across varying surgical experience. The study included two separate cohorts: 6,091 patients treated by open radical prostatectomy and an independent replication set of 2,298 patients treated laparoscopically. We calculated the odds ratios for biological predictors of biochemical recurrence—stage, Gleason grade and prostate‐specific antigen (PSA)—and also the predictive accuracy (area under the curve, AUC) of a multivariable model, for subgroups of patients defined by the experience of their surgeon. In the open cohort, the odds ratio for Gleason score 8+ and advanced pathologic stage, though not PSA or Gleason score 7, increased dramatically when patients treated by surgeons with lower levels of experience were excluded (Gleason 8+: odds ratios 5.6 overall vs. 13.0 for patients treated by surgeons with 1,000+ prior cases; locally advanced disease: odds ratios of 6.6 vs. 12.2, respectively). The AUC of the multivariable model was 0.750 for patients treated by surgeons with 50 or fewer cases compared to 0.849 for patients treated by surgeons with 500 or more. Although predictiveness was lower overall for the independent replication set cohort, the main findings were replicated. Surgery confounds biology. Although our findings have no direct clinical implications, studies investigating biological variables as predictors of outcome after curative resection of cancer should consider the impact of surgeon‐specific factors.
Hospital self‐discharge among adults with sickle‐cell disease (SCD): Associations with trust and interpersonal experiences with care

Published: June 2010

AbstractBACKGROUND:Patient self‐discharge from hospitals has been associated with a number of negative clinical outcomes. Research suggests that low patient trust and poor quality interpersonal experiences with care may be associated with hospital self‐discharge. Although adults with sickle‐cell disease (SCD) often report poorer quality healthcare experiences, research examining hospital self‐discharge and its associations with both patient trust and quality of healthcare experiences is lacking for this patient population.OBJECTIVE:To examine the association of interpersonal experiences with care and trust in the medical profession with hospital self‐discharge history among patients with SCD.DESIGN:Cross‐sectional study.SETTING:A large, urban academic medical center.PATIENTS:Adults (age 18+ years) with SCD seeking outpatient or inpatient care.MEASUREMENTS:We compared patient characteristics, patient perceptions of the quality of interpersonal experiences with care, and levels of trust between patients with and without a history of hospital self‐discharge.RESULTS:Adjusted analyses indicated that having a history of hospital self‐discharge was associated with more negative interpersonal experiences and lower levels of trust.CONCLUSIONS:Hospital self‐discharge may be an important indicator of the quality of care received by adults with SCD. Further research is needed to better understand this phenomenon so that effective interventions can be designed to prevent its occurrence.

Comparative morphology of the head of selected sporophagous and non‐sporophagous aleocharinae (Coleoptera: Staphylinidae): Musculature and hypopharynx‐prementum complex
Authors: Weide Daniela , Thayer Margaret K. , Newton Alfred F. , Betz Oliver 
Published: June 2010

AbstractTo investigate whether specialization to spore‐ (or pollen‐) feeding in advanced Aleocharinae is mirrored by their head anatomy, we compiled and compared synchrotron X‐ray micro‐tomography datasets for 11 Aleocharinae in conjunction with previous data for two aleocharine and six outgroup species (two nonstaphylinids, four staphylinids). We describe the presence/absence of head muscles and investigate the variability of points of origin by character mapping analyses. Monophyly of Aleocharinae is supported by the absence of M. 48 (M. tentoriobuccalis anterior), and by changes in the origins of Mm. 1, 2, 17, 18, 28, 29, 30. Within Aleocharinae the origins of the labial muscles (Mm. 28–30) have shifted posteriorly to the gula, which might enhance the movement posterad of the hypopharynx and partly compensate for the loss of M. 48. We also analyzed the general organization of the hypopharynx‐prementum complex and the fine structure of the mandibles through SEM studies. In the absence of grinding mandibular molae like those of most mycophagous Coleoptera, seven aleocharine species studied have evolved “pseudomolae” at the ventral side of the mandibles that replace true molae as secondary grinding surfaces. In these species, the hypopharynx is elevated and displaced anteriorly, bearing a bowl‐like depression on its surface that functions as a mortar where spores are ground between the hypopharynx and the mandibles. Two of these species are not yet known to feed on spores or pollen. Another species (Oxypoda alternans) is thought to feed on fungus material but bears no pseudomolae on its mandibles. J.

Rapid monitoring of arrays of amino acids in clinical samples using capillary electrophoresis with contactless conductivity detection
Authors: Tůma Petr , Málková Klára , Samcová Eva , Štulík Karel 
Published: June 2010

AbstractCE with contactless conductivity detection has been used to separate 28 biogenic amino acids in a short capillary with an effective length of 18 cm. All the tested amino acids can be mutually separated in 0.5–10 mol/L acetic acid electrolytes. The time of analysis does not exceed 6 min and the LODs vary from 0.1 to 1.7 μmol/L. The CVs lie within the intervals 0.01–0.4% and 0.9–4% for the migration times and the analyte peak areas, respectively. The procedure has been successfully applied to the determinations of the whole amino acid spectra in blood plasma, urine, saliva and cerebrospinal fluid samples.

AbstractBackgroundThe majority of minimal residual disease (MRD)‐positive patients with acute lymphoblastic leukemia (ALL) have poor outcomes. The ALL2000 study was performed to evaluate the efficacy of augmented chemotherapy based on MRD‐restratification in childhood ALL.ProcedureBetween 2000 and 2004, 305 eligible patients with precursor B or T‐cell ALL were enrolled in the ALL2000 study. The ALL941‐based therapy protocol utilized PCR MRD assays using Immunoglobulin and T‐cell receptor gene rearrangements. They were initially stratified into three risk‐groups according to leukocyte count and age, and MRD levels were measured at weeks 5 (TP1) and 12 (TP2) for a second stratification. From week 14, patients with MRD levels $ \mathbin{\lower.3ex\hbox{$\buildrel>\over {\smash{\scriptstyle=}\vphantom{_x}}$}} 10^{ - 3} $ received an increase in therapy (one risk group higher), while the remainder continued to receive the initial risk‐adapted therapy.ResultsThe overall 5‐year event‐free survival (EFS) rate for ALL2000 was 79.7 ± 2.4%. MRD stratification was feasible for 234 of 301 patients (77%) who achieved complete remission. The EFS rate of the MRD stratifiable (MRD) group was 82.5 ± 2.6%, considerably superior to the 74.7 ± 5.7% of MRD non‐stratifiable (Non‐MRD) group (P = 0.084) and the 74.4 ± 2.1% for ALL 941 (P = 0.012). MRD‐positive patients at TP2 showed inferior outcomes as compared with MRD‐negative cases, but the difference did not reach a statistically significant level in any risk groups or immunophenotypes.ConclusionsThese results suggest that augmented therapy for MRD‐positive patients at TP2 contributed to better outcomes of the ALL2000 study.

A robust user authentication scheme with self‐certificates for wireless sensor networks
Authors: Tseng Huei‐Ru , Jan Rong‐Hong , Yang Wuu 
Published: June 2010

AbstractUser authentication is a critical part of security, along with confidentiality and integrity, for computer systems that allow legitimate users remote access over an open communication network. Recently, user authentication for wireless sensor networks (WSNs) has received considerable attention. We propose a robust user authentication scheme for WSNs. The scheme is based on elliptic‐curve cryptosystems with self‐certificates. The proposed scheme allows users to change their key pairs without interaction with a key distribution center (KDC). Moreover, the proposed scheme still works well even if the adversary capturestnodes out ofnnodes in the WSNs. Security of the proposed scheme is modeled and analyzed with Petri nets. Our analysis shows that the proposed scheme can successfully defend some of the most notorious attacks, including replay attacks, forgery attacks, and node‐capture attacks.

Comparison of the Frying Stability of Sunflower and Refined Olive Pomace Oils With/Without Adsorbent Treatment
Authors: Bulut Erdim , Yılmaz Emin 
Published: June 2010

AbstractThe aim of this study was to compare the frying behaviors of refined olive pomace (ROP) oil to sunflower oil in a 5‐day trial, and to evaluate the refresh capacity of a new adsorbent mixture composed of diatomaceous earth, zeolite and lime. Frying trials were performed as control and adsorbent‐treated groups. Oil samples collected after each day of frying were analyzed for physical characteristics (viscosity, turbidity, refractive index, smoke point), color values (L, a* and b*), and chemical properties (free acidity, peroxide value, conjugated dienoic acids, total polar materials). The amount of oil absorbed by the fried dough was measured. In general, results indicated that ROP oil had higher thermal stability. There were no significant differences between the quality parameters of control and adsorbent treated samples for either oil sample. Effectiveness of the new adsorbent mixture on frying oil refreshing was limited only to free acidity, viscosity, and color. Total polar materials measured with probe sensor were determined to be as accurate as the official technique, and can be recommended for quick, easy and cheap analysis. Also, there were some significant correlations between the measured oil quality parameters.
Cell of origin of lung cancer
Authors: Sutherland Kate D. , Berns Anton 
Published: June 2010

AbstractLung cancer is a devastating disease and a major therapeutic burden with poor survival rates. The discovery of rare cells with stem cell‐like properties in solid tumours is emerging as an important area of cancer research and may help explain the resistance of these tumours to current therapeutics. Despite rapid developments in cancer stem cell research in other solid tumours, progress in the lung has been hampered by an incomplete understanding of the epithelial stem cell hierarchy, the heterogeneity of disease and the lack of a suitable in vivo transplantation model to assess stem cell behaviour. In this review we critically discuss what is currently known about the role of normal stem cells and cancer‐initiating cells in lung tumour development, and briefly discuss strategies aimed at advancing the field of lung stem cell biology, with an emphasis on the design and manipulation of state‐of‐art mouse models.
The influence of Al2O3 on the H2O content in periclase and ferropericlase at 25 GPa
Authors: Litasov K.D. 
Published: June 2010

Abstract
In this paper I present results of IR spectroscopic measurements of water solubility in Al-bearing periclase and ferropericlase (Mg# = 88) synthesized at 25 GPa and 1400–2000 °C. The IR spectra of their crystals show narrow absorption peaks at 3299, 3308, and 3474 cm−1. The calculated H2O contents are 11–25 ppm in periclase (Al2O3 = 0.9–1.2 wt.%) and 14–79 ppm in ferropericlase (Al2O3 = 0.9–2.9 wt.%). Ferropericlase contains more H2O and Al2O3 than periclase at 1800–2000 °C. I suggest that addition of Al2O3 does not influence the solubility of water in ferropericlase but can favor the additional incorporation of Fe2O3 into the structure. The incorporation of Fe3+ into ferropericlase increases water solubility as a result of iron reduction to Fe2+. It is shown that water has limited solubility in ferropericlase from mantle peridotite; therefore, ferropericlase cannot be considered an important hydrogen-bearing mineral in the lower mantle.

Published: June 2010

Abstract
This work is a review of the modern concepts of the accumulation of Fe and Mn in the Baikal bottom sediments and the regularities of formation of iron-manganese (including phosphate-bearing) nodules in the lake. Special attention is given to the probable participation of hydrothermal water in this process and the genesis of ancient nodules deeply buried in the Baikal sediments. The possible relationship between the shore ores and the nodules in the bottom sediments in the adjacent Baikal regions has been first shown.
Essai d'éthique fondamentale. Ouvrage Posthume de Georges Bastide et la Philosophie Bastidienne
Authors: Gabaude Jean-Marc 
Published: June 2010

Après avoir cité le mot de Bergson: “Un philosophe dignedece nom n'a jamais dit qu'une seule chose,” Robert Blanché, au début de sa préface au dernier ouvrage de Georges Bastide, Essai d'Ethique fondamentale, pr´esente ainsi l'œuvre philosophique bastidienne: «Riche par l'ampleur du champ, diverse par la variété des approches, renouvelée par l'ingéniosité et la finesse des analyses, elle demeure centrée sur un unique problème, et elle ne varie pas dans la réponse. Le probléme qui est ou qui devrait être notre problème à tous, se lit, dès le départ sur la couverture du premier livre: De la condition humaine.» L'ouvrage posthume de Georges Bastide est le plus riche de ses écrits et l'un des plus beaux témoignages de la philosophic de 1'esprit. L'on y retrouve, par surcroît, la maîtrise du verbe, le styl d'orateur et les images du grandécrivain de la langue française qu'était Georges Bastide. Get ultime ouvrage présente son auteur« Tel qu'en lui-même enfin l'éternité le change » pour employer ce vers mallarméen aim´ par G. Bastide.
Réflexions sur une théologie de la révolution
Authors: Declève Henri 
Published: June 2010

I. La « Théologie de la révolution » de J. Comblin.Quand un prêtre beige, ills apparemment d'une famille bourgeoise, docteur en théologie de Louvain, part exercer des charges pastorales puis devient professeur de séminaire en Amérique latine, spécialement dans le diocèse de don Helder Camara, il est évidemment contraint de se rendre compte que son ministère et son enseignement ne sauraient trouver ni le moindre sens ni la moindre audience en dehors d'une perspective révolution-naire. La révolution est en effet l'horizon de l'expérience que vit présentement l'Amérique latine, en communion avec les mouvements de libération qui se font jour dans le monde entier.
Le concept d'idèologie et les conditions socio-politiques de son usage
Authors: Poulain Jacques 
Published: June 2010

Toutes les idéologies recouvrent-elles une égale meéonnais-sance de la réalité ?Le terme d' «idéologie », brandi comme arme idéologique, vise « une doctrine fondée sur des idées sans rapport avec les faits réels » (Dictionnaire Larousse). Ce système transmissible de rapports ne se rapporte plus lui-même à la réalité: celle-ci peut être subsumée sous ses concepts organisés en dogmes, elle ne peut plus ou n'a jamais pu être reconnue. L'adversaire de l'idéologie se donne pour tâche de faire reconnaître «la » réalité en découvrant les réalités qu'il estime essentielles, en même temps qu'il en dénonce la mécon-naissance chez l'idéologue. L'idéologie attaquée constituant l'idéolo-gie typique, toutes les idéologies ne font à ses yeux que reproduire cette méconnaissance radicale: l'une n'a pas plus de valeur de vérité qu'une autre, elles recouvrent toutes une égale absence de rapports avec le réel. Elles sont toutes aveugles au même titre et ne reconnaissent pas davantage cet aveuglement que la réalité qu'elles ignorent.
Le Marxisme de Sartre: Mystification ou réalité?
Authors: Gervais Charles 
Published: June 2010

Dans un premier article sur le rapport à établir entre les problématiques sartrienne et marxiste é la lumière de la Critique de la Raison Dialectique, nous avions tenté de circonscrire projet spécifique de Sartre face au Savoir marxiste.Nous aimerions poursuivre aujourd'hui notre réflexion par une analyse de quelques thèmes majeurs nous permettant de voir dans quelle mesure et dans quel sens ces deux problématiques se recoupent ou non. A cet effet, nous distinguerons: I) le problème du matérialisme et de la dialectique, 2) la conception de l'homme, 3) la perspective de base (rareté et surproduit), 4) le concept de classe.
