Remediation of Radionuclide Pollutants through Biosorption – an Overview
Authors: Das Nilanjana 
Published: November 2011

AbstractThe development of nuclear science and technology has led to the increase of nuclear wastes containing radionuclides to be released and disposed in the environment. Pollution caused by radionuclides is a serious problem throughout the world. To solve the problem, substantial research efforts have been directed worldwide to adopt sustainable technologies for the treatment of radionuclide containing wastes. Biosorption represents a technological innovation as well as a cost effective excellent remediation technology for cleaning up radionuclides from aqueous environment. A variety of biomaterials viz. algae, fungi, bacteria, plant biomass, etc. have been reported for radionuclide remediation with encouraging results. This paper reviews the achievements and current status of radionuclide remediation through biosorption which will provide insights into this research frontier.

Published: November 2011

AbstractIn this study, a full survey of pollutant sources and water quality was conducted, followed by the application of a water quality model (Water Quality Analysis Simulation Program, WASP) to establish strategies of water quality control in Carp Lake, Taiwan. Results of the field investigation show that both point and non‐point source (NPS) pollutants were responsible for the poor water quality. The contributions of biochemical oxygen demand (BOD) from point source and NPS pollution were 45.9 and 55.1%, respectively. About 80% of total phosphorus (TP) were contributed by NPS. Additionally, point source and NPS pollution discharged 55.5 and 44.5% of NH3–N load, respectively. The Carlson's Trophic State Index ranged from 61.9 to 69.2 showing serious eutrophic problems in Carp Lake. The calculated BOD, NH3–N, and TP carrying capacity were approximately 2.8, 0.42, and 0.15 kg per day, respectively. However, the current pollutant loadings are approximately 3.0–5.5 times the calculated carrying capacity. With the help of the calibrated WASP model, remedial strategies for the lake water from short‐term to long‐term were developed. The completion of the small local sewer system to remove 80% of the point source pollution can serve as a short‐term goal while 40–60% of NPS removal by natural treatment systems may serve as a mid‐term goal. Furthermore, 80% of both source point and NPS pollution removal can be considered as a long‐term strategy. Results of heavy metal analysis show that the enriched sediment would be safe for agricultural applications.
Durability of Polymer Electrolyte Membrane Fuel Cell with Pt/CNTs Catalysts in Cell Reversal Conditions by Hydrogen Starvation

Published: November 2011

AbstractThe durability of polymer electrolyte membrane fuel cell with Pt catalysts supported on carbon nanotube (CNT) was investigated after a few hundred accelerated cell reversal process (RP) cycles generated by hydrogen deficiency. A variety of characterization techniques, including cell performance tests, were applied to examine the effects of CNT support on the degradation of Pt catalysts: transmission electron microscopy, electrochemical impedance spectroscopy, and cyclic voltammetry. During the RP cycle tests, most degradation by carbon corrosion occurred at the outlet region of membrane electrode assembly (MEA) where hydrogen starvation seriously occurred. By using the CNT as the support of Pt catalysts in the MEA cathode, carbon corrosion was reduced and growth of Pt particles by agglomeration and sintering significantly decreased. Compared to a commercial Pt/C catalyst, the cell durability of the Pt/CNT catalyst was enhanced under the RP condition.

AbstractBackground: Trait impulsiveness is a potential factor that predicts both substance use and certain psychiatric disorders. This study investigates whether there are common structural cerebral correlates of trait impulsiveness and cognitive functioning in a large sample of healthy adolescents from the IMAGEN project. Methods: Clusters of gray matter (GM) volume associated with trait impulsiveness, Cloningers' revised temperament, and character inventory impulsiveness (TCI‐R‐I) were identified in a whole brain analysis using optimized voxel‐based morphometry in 115 healthy 14‐year‐olds. The clusters were tested for correlations with performance on the nonverbal tests (Block Design, BD; Matrix Reasoning, MT) of the Wechsler Scale of Intelligence for Children IV reflecting perceptual reasoning. Results: Cloningers' impulsiveness (TCI‐R‐I) score was significantly inversely associated with GM volume in left orbitofrontal cortex (OFC). Frontal clusters found were positively correlated with performance in perceptual reasoning tasks (Bonferroni corrected). No significant correlations between TCI‐R‐I and perceptual reasoning were observed. Conclusions: The neural correlate of trait impulsiveness in the OFC matches an area where brain function has previously been related to inhibitory control. Additionally, orbitofrontal GM volume was associated with scores for perceptual reasoning. The data show for the first time structural correlates of both cognitive functioning and impulsiveness in healthy adolescent subjects. Hum Brain Mapp, 2013. © 2011 Wiley Periodicals, Inc.
Aberrant expression of CD133 and musashi‐1 in preneoplastic and neoplastic human oral squamous epithelium and their correlation with clinicopathological factors
Authors: Ravindran Gokulan , Devaraj Halagowder 
Published: November 2011

AbstractBackgroundThe present study focuses on the expression pattern of the stem cell markers CD133 and Musashi‐1 in precancerous and cancerous tissues of oral epithelium. The study also aims to investigate the correlation of CD133 and Musashi‐1 expression with clinicopathological factors.MethodsImmunohistochemical analysis was done to investigate the expression pattern of CD133 and Musashi‐1, whereas, the coexpression of CD133 and Musashi‐1 was studied using immunofluorescence analysis.ResultsA gradual increase in the expression of CD133 and Musashi‐1 was observed from normal to dysplasia to carcinoma. In addition, the expression of CD133 and Musashi‐1 shows significant difference between the stages and histological types of oral carcinoma. Interestingly, coexpression of CD133 and Musashi‐1 was observed in oral carcinoma and CAL27 cells.ConclusionsA gradual increase in the expression of CD133 and Musashi‐1 from normal to dysplasia to carcinoma suggests the possible involvement of these 2 proteins in oral carcinogenesis. The overexpression of CD133 and Musashi‐1 in advanced stages and also in poorly differentiated tumors reveals their relationship with invasion and differentiation status of oral carcinoma cells. Moreover, the significant positive correlation between CD133 and Musashi‐1 expression suggests that they might have a functional relationship in oral carcinoma cells, which needs further investigation. © 2011 Wiley Periodicals, Inc.

AbstractBackgroundPostintubation tracheal stenosis (PITS) is associated with an increased use of assisted ventilation in intensive care units. We investigated both collagen type I accumulation and myofibroblast localization in human PITS lesions excised for surgical therapeutic procedures, compared with normal tracheas.MethodsWe analyzed 2 segments of normal tracheas and 10 segments of PITS that were stained by hematoxylin–eosin and picrosirius red techniques and processed for immunohistochemistry using antibodies against both α‐smooth muscle actin (α‐sma) for myofibroblast detection, and collagen type I.ResultsWe showed a significant increase in collagen deposition in PITS specimens compared with normal tracheas. We found spindle‐shaped α‐sma‐positive cells (myofibroblasts) in the subepithelial layer of all pathologic tracheas, and the persistence of an intense myofibroblast network at PITS sites.ConclusionsTracheal wall thickening in PITS is due to a deranged collagen remodeling that is related to myofibroblast activation. © 2011 Wiley Periodicals, Inc.

Novel thermal effect at nanoshell heating by pulsed laser irradiation: hoop‐shaped hot zone formation
Authors: Avetisyan Yuri A. , Yakunin Alexander N. , Tuchin Valery V. 
Published: November 2011

AbstractPhotonic nanotechnologies have good perspectives to be widely used in biophotonics. In this study we have developed an approach for calculation of nanoparticle temperature field accounting for absorbed local intensity at pulse laser radiation of composite spherical nanoparticles (nanoshells). This approach allowed us to analyze spatial inhomogeneities of light field diffracted into a nanoshell and corresponding distribution of the absorption energy and to provide numerical solution of time‐dependent heat conduction equation accounting for corresponding spatially inhomogeneous distribution of heating sources. We were able to predict the appearance of a novel thermal effect – hoop‐shaped hot zone on the nanoshell surface. The observed effect has potential applications in cell biology and medicine for controlled cell optoporation and nanosurgery, as well as cancer cell killing. (© 2012 WILEY‐VCH Verlag GmbH & Co.

Authors: Almeida Lidiane A. , Marques Maria de Fátima V. 
Published: November 2011

AbstractExperiments designed to prepare Ziegler‐Natta catalysts with controlled particle morphology are reported. Different dealcoholation processes are used on the adduct MgCl2 · nEtOH to prepare the catalysts: either thermal treatment or chemical dealcoholation employing different substances such as titanium tetrachloride, triethylaluminium, dichlorodimethylsilane, and chlorotrimethylsilane. In addition, dichlorodimethylsilane dealcoholation is also performed after thermal treatment. SEM analysis of adducts, supports, and catalysts is carried out. The obtained catalysts are characterized through impregnated titanium content evaluation. The polyethylenes and poly(propylene)s obtained employing the so prepared catalysts show spherical morphology when examined by optical microscopy.magnified image
Which Dimensions of Fatigue Should be Measured in Patients with Rheumatoid Arthritis? A Delphi Study

Published: November 2011

AbstractObjectiveRheumatoid arthritis (RA) patients experience fatigue as a multidimensional symptom. The aim of the present study was to use health professionals and patients alike to identify which dimensions of fatigue should be measured in RA.MethodsTwelve fatigue dimensions were constructed, based on items from traditional questionnaires and items generated from interviews. Health professionals and patients evaluated these dimensions, related to an initial pool of 294 items, in a Delphi procedure. Dimensions were selected if rated important by at least 80% of the participants.ResultsTen rheumatologists, 20 nurses and 15 patients participated. All fatigue dimensions were selected directly (severity, frequency, duration, changes in fatigue, perceived causes of fatigue, energy, sleep/rest, body feeling, cognition/concentration, coping, negative emotions/mood and consequences). No additional dimensions emerged from participants' comments and suggestions.ConclusionsThis study revealed 12 fatigue dimensions. This underlines the multidimensionality of fatigue in RA and the need for comprehensive measurement. Copyright © 2011 John Wiley & Sons, Ltd.
Incrementally non‐linear plasticity applied to rock joint modelling
Authors: Duriez Jérôme , Darve Félix , Donzé Frédéric‐Victor 
Published: November 2011

SUMMARYRock joint constitutive modelling is discussed through two new rock joint constitutive relations and a discrete numerical model. Regarding the constitutive relations, we emphasise the number of ‘tensorial zones’, that is, domains of constitutive incremental linearity; they involve four zones for the first (called ‘quadrilinear’) and an infinite number for the second one (called ‘incrementally nonlinear’). Using these formulations, a large class of loading paths can be considered. Hardening through shearing and relations between the normal and tangential directions of the joint (e.g., dilatancy) can be described. Their predictive abilities are checked. Plastic features are included even if the relations are defined outside the elasto‐plastic formalism. These relations obey, hence, the physical evidence as the plastic limit criterion and flow rule. The flow rule is nonassociated, and the corresponding link with the nonsymmetry of the constitutive matrix is examined. Comparisons between the two relations and the discrete numerical model, that is, a direct numerical simulation, which is fundamentally different, also are discussed within the context of infilled rock joints.

Published: November 2011

AbstractBased on two aggregation‐induced light‐emitting materials, N‐(4‐(benzo[d]thiazol‐2‐yl)‐3‐hydroxyphenyl) anthracene‐9‐carboxamide for yellow emission and N‐(4‐(benzo[d]oxazol‐2‐yl)‐4‐tert‐butylbenzamide for Blue emission, non‐doped white organic light‐emitting diodes have been realized. The maximum efficiency of 2.2 cd/A and the Commission International de L'Eclairage coordinates of (0.32, 0.33) are achieved. Moreover, the device efficiency and color coordinates change slightly with increasing driving current density up to 500 mA/cm2, showing a good color stability and a small efficiency roll‐off. This may due to both better confinement of excitons within the emitting layer and the utilization of a thin layer of emitting material with aggregation‐induced emission.

AbstractThe depth strain profile in silicon from the Si (001) substrate to the surface of a 2 nm thick Si/12 nm thick SiGe/bulk Si heterostructure has been determined by medium energy ion scattering (MEIS). It shows with sub‐nanometer resolution and high strain sensitivity that the thin Si cap presents residual compressive strain caused by Ge diffusion coming from the fully strained SiGe layer underneath. The strain state of the SiGe buffer have been checked by X‐ray diffraction (XRD) and nano‐beam electron diffraction (NBED) measurements.

ABSTRACTLand use changes and channelization of streams in the deep loess region of western Iowa have led to stream channel incision, altered flow regimes, increased sediment inputs, decreased habitat diversity and reduced lateral connectivity of streams and floodplains. Grade control structures (GCSs) are built in streams to prevent further erosion, protect infrastructure and reduce sediment loads. However, GCS can have a detrimental impact on fisheries and biological communities. We review three complementary biological and hydraulic studies on the effects of GCS in these streams. GCS with steep (≥1:4 rise : run) downstream slopes severely limited fish passage, but GCS with gentle slopes (≤1:15) allowed greater passage. Fish assemblages were dominated by species tolerant of degradation, and Index of Biotic Integrity (IBI) scores were indicative of fair or poor biotic integrity. More than 50% of fish species had truncated distributions. After modification of GCS to reduce slopes and permit increased passage, IBI scores increased and several species were detected further upstream than before modification. Total macroinvertebrate density, biomass and taxonomic diversity and abundance of ecologically sensitive taxa were greater at GCS than in reaches immediately upstream, downstream or ≥1 km from GCS. A hydraulic study confirmed results from fish passage studies; minimum depths and maximum current velocities at GCS with gentle slopes (≤1:15) were more likely to meet minimum criteria for catfish passage than GCS with steeper slopes. Multidisciplinary approaches such as ours will increase understanding of GCS‐associated factors influencing fish passage, biological assemblage structure and other ecological relationships in streams.

Published: November 2011

ABSTRACTThe transition to adulthood is characterised by potential for both positive development and problem outcomes such as psychopathology, yet little is known about relationships between the two. Given the diversity of pathways observed during this transition period, there is likely to be significant heterogeneity in young people’s experiences of these outcomes. Drawing on data from 1158 19–20 year olds in the Australian Temperament Project and using latent profile analysis, we identified six subgroups. For most, higher positive development was associated with lower psychopathology and vice versa. One group (33.6%) was high across all positive development measures and low on psychopathology, and another (47.7%) average in both areas. The remaining four groups were low on positive development but differentiated by average psychopathology (4.7%), high internalising (5.5%), and moderate (7.2%) and severe (1.3%) externalising problems. Tailored intervention strategies that address both the promotion of competence and prevention of problem outcomes are needed.

Published: November 2011

ABSTRACTParental promotion of autonomy for offspring well‐being has been widely recognized in developmental psychology. Recent studies, however, show that this association varies across cultures. Such variation may reflect inappropriate measurement of this dimension of parenting. Therefore, three existing measures of promotion of autonomy were used to derive different dimensions related to the promotion of autonomy in three different domains – promotion of autonomous thought, promotion of autonomous decision‐making, and promotion of physical separation. The cross‐cultural significance of this three‐component model was tested in samples of late adolescents (n = 1361) from four nations‐ the US, Belgium, Italy and China. Data from all four countries best fit a three dimensional model but the covariance between the three dimensions was moderated by culture. Culture also moderated the impact of promotion of autonomy on offspring well‐being.

SUMMARYA total of 111 clinical and environmental O1, O139 and non-O1/O139Vibrio choleraestrains isolated between 1978 and 2008 from different geographical areas were typed using a combination of methods: antibiotic susceptibility, biochemical test, serogroup, serotype, biotype, sequences containing variable numbers of tandem repeats (VNTRs) and virulence genesctxAandtcpAamplification. As a result of the performed typing work, the strains were organized into four clusters: cluster A1 included clinical O1 Ogawa and O139 serogroup strains (ctxA+andtcpA+); cluster A2 included clinical non-O1/O139 strains (ctxA−andtcpA−), as well as environmental O1 Inaba and non-O1/O139 strains (ctxA−andtcpA−/tcpA+); cluster B1 contained two clinical O1 strains and environmental non-O1/O139 strains (ctxA−andtcpA+/tcpA−); cluster B2 contained clinical O1 Inaba and Ogawa strains (ctxA+andtcpA+). The results of this work illustrate the advantage of combining several typing methods to discriminate between clinical and environmentalV. choleraestrains.
Relationship between the level of antibodies in bulk tank milk and the within-herd seroprevalence of Coxiella burnetii in cows
Authors: TAUREL A.-F. , GUATTEO R. , JOLY A. , BEAUDEAU F. 
Published: November 2011

SUMMARYThe relationship between the level of antibodies in bulk tank milk (BTM) and the within-herd seroprevalence of Coxiella burnetii in cows was assessed. Blood from milking cows and BTM were sampled in 55 infected herds and tested using commercial enzyme-linked immunosorbent assay (ELISA) kits. The relationship between antibody levels and WHP, which was quantified using a general linear model, was only moderate (R2=0·15). Nevertheless, the lowest antibody level in BTM was associated with the lowest mean within-herd prevalence. The present finding indicates that ELISA applied to BTM could identify infected herds with quite low within-herd seroprevalence. For such herds, the vaccination of dairy cows as well as nulliparous heifers using a phase I vaccine could effectively prevent C. burnetii shedding.
