Remediation of heavy metals in drinking water and wastewater treatment systems: processes and applications.

In small quantities, certain heavy metals are nutritionally essential for a healthy life. The heavy metals linked most often to human poisoning are lead, mercury, arsenic and cadmium. Other heavy metals, including copper, zinc and chromium are actually required by the body in small amounts, but can also be toxic in larger doses. They have the ability of dissolving in wastewaters and when discharged into surface waters, they can be concentrated and travel up the food chain. They can also seep into groundwater, hence contaminating drinking water, thereby harming the consumers of that water. The enactment of several water legislations and guidelines worldwide coupled with the need for environmental sustainability has necessitated the need for several stringent regulations for drinking water supply and wastewater discharge. To achieve unpolluted drinking water distribution and wastewater discharge, several technologies and processes for heavy metal remediation are currently in use. This review was therefore aimed at elucidating the major available technologies for heavy metal remediation in water, with emphasis on their processes and applications. Currently, no one of the existing technologies for heavy metal remediation (chemical remediation, phytoremediation or microbial remediation) is without some form of merits and demerits. There is therefore a proposed need for the utilization of safe and economical multiple/integrated approach for heavy metal remediation. The application of this may offer enormous public health, environmental and cost benefits. Key words: Heavy metals, remediation, water.
Isoindigo-Based Small Molecules with Varied Donor Components for Solution-Processable Organic Field Effect Transistor Devices

Two solution-processable small organic molecules, (E)-6,6′-bis(4-(diphenylamino)phenyl)-1,1′-bis(2-ethylhexyl)-(3,3′-biindolinylidene)-2,2′-dione (coded as S10) and (E)-6,6′-di(9H-carbazol-9-yl)-1,1′-bis(2-ethylhexyl)-(3,3′-biindolinylidene)-2,2′-dione (coded as S11) were successfully designed, synthesized and fully characterized. S10 and S11 are based on a donor-acceptor-donor structural motif and contain a common electron accepting moiety, isoindigo, along with different electron donating functionalities, triphenylamine and carbazole, respectively. Ultraviolet-visible absorption spectra revealed that the use of triphenylamine donor functionality resulted in an enhanced intramolecular charge transfer transition and reduction of optical band gap, when compared with its carbazole analogue. Both of these materials were designed to be donor semiconducting components, exerted excellent solubility in common organic solvents, showed excellent thermal stability, and their promising optoelectronic properties encouraged us to scrutinize charge-carrier mobilities using solution-processable organic field effect transistors. Hole mobilities of the order of 2.2 × 10−4 cm2/Vs and 7.8 × 10−3 cm2/Vs were measured using S10 and S11 as active materials, respectively.
Rethinking Indirect Aggression: The End of the Mean Girl Myth

Abstract Although much has been made of the “mean girl” and her use of indirect aggression, this cross-cultural study of 5,789 adolescents from six countries (Austria, Canada, Germany, Slovenia, Spain, and Switzerland) found that significantly more boys (46.8%) than girls (31.7%) reported using indirect aggression against peers. Additionally, because females reported an almost 19 times higher probability than males for using indirect aggression against opposite sex peers, males are by far the more likely targets of indirect aggression—thus suggesting that indirect aggression is a male, not a female, issue.
The role of visibility for a minority’s exposure to (hate) crime and worry about crime – a study of the Traveller community

This study examines Travellers, a subset of the Roma minority; exposure to (hate) crime; and worry about criminal victimization in Sweden. Previous research has shown that the Roma in many respects constitute a marginalized group that is vulnerable to both discrimination and other criminal acts. This is problematic since there is a risk that minorities who are victims of crimes may be further stigmatized and may also lose cultural expression. The data are collected from a sample of Travellers living in the Gothenburg region of Sweden (N = 121). Approximately one fifth of the respondents stated that they had experienced anti-Roma motivated victimization during the previous 12 months and as many as 84% stated that they had been the victims of such a crime at some point during their lifetime. The respondents also reported a high level of worry about criminal victimization, and 3 out of 10 respondents stated that their quality of life was highly affected by worry about crime. Further, a tendency was noted toward a higher degree of victimization, but a lower degree of worry, among those respondents who were open about their ethnicity by comparison with those who were not.
Primary corneal graft failure. A national reporting system.

The Eye BankAssociation of America, Washington, DC, which was founded in 1961, has functioned primarily to serve corneal transplant recipients, corneal surgeons and its individual member eye banks through educational seminars, the development and later implementation of strict medical standards, and the use of on-site inspection teams to ensure the highest quality donor eye tissue. Human immunodeficency virus (HIV) testing of donor serum samples by eye banks, for example, was mandated at least 2 years prior to similar requirements for organ donors by the United Network for Organ Sharing. In this issue of theArchives, Wilhelmus and colleagues,1working with the Medical Advisory Board of the Eye Bank Association of America, have analyzed adverse reaction forms completed by eye bank medical directors in an effort to identify risk factors for first postoperative day cloudy corneal grafts that never clear (primary donor failures). The authors summarize in Table 4
Memory functioning in post-traumatic stress disorder: objective findings versus subjective complaints

Although memory complaints are common in post-traumatic stress disorder (PTSD), the only published study of objective and subjective memory in PTSD by Roca and Freeman indicates that subjective complaints may not accurately refl ect objective performance. The present study examined memory in 21 PTSD patients, 20 combat controls and 23 non-combat controls using two objective memory measures (Rey Auditory Verbal Learning Test; Backward Digit Span) and one subjective measure (Memory Functioning Questionnaire). Analysis of variances (ANOVAs) and analysis of co-variances generally did not reveal group differences for objective memory performance. For subjective memory complaints, ANOVAs indicated group differences; PTSD participants reported more memory problems than controls. These differences disappeared, however, when depression was included as a covariate. Also, we provide some preliminary evidence that depression may mediate the relationship between PTSD symptomatology and subjective memory complaints. Findings suggest that reductions in depressive symptomatology in PTSD may be associated with decreased subjective memory complaints. Copyright © 2010 John Wiley & Sons, Ltd.
Development of Spatial and Verbal Working Memory Capacity in the Human Brain

A core aspect of working memory (WM) is the capacity to maintain goal-relevant information in mind, but little is known about how this capacity develops in the human brain. We compared brain activation, via fMRI, between children (ages 7–12 years) and adults (ages 20–29 years) performing tests of verbal and spatial WM with varying amounts (loads) of information to be maintained in WM. Children made disproportionately more errors than adults as WM load increased. Children and adults exhibited similar hemispheric asymmetry in activation, greater on the right for spatial WM and on the left for verbal WM. Children, however, failed to exhibit the same degree of increasing activation across WM loads as was exhibited by adults in multiple frontal and parietal cortical regions. Thus, children exhibited adult-like hemispheric specialization, but appeared immature in their ability to marshal the neural resources necessary to maintain large amounts of verbal or spatial information in WM.
Final lowering and boundary pitch movements in spontaneous Japanese

Standard theory of the prosodic structure in Tokyo Japanese treats both the final lowering and boundary pitch movements as the properties of utterance node. Validity of this treatment was examined by means of corpus-based analyses of spontaneous speech. The results showed that while final lowering could be treated as a property of utterance, boundary pitch movement could not. The latter should rather be treated as the property of accentual phrase. Based on these results, revised prosodic structure and annotation scheme were proposed.
Is a Risky Lifestyle Always “Risky”? The Interaction Between Individual Propensity and Lifestyle Risk in Adolescent Offending: A Test in Two Urban Samples

This study examines the effects on adolescent offending of lifestyle risk and the individual propensity to offend. It is assumed that lifestyle risk will have a more important effect on offending for those individuals with high levels of individual propensity, whereas for individuals with low levels of individual propensity it is assumed that a risky lifestyle will not, or will only marginally, influence their involvement in offending. The data are drawn from two different samples of young adolescents in Antwerp, Belgium (N = 2,486), and Halmstad, Sweden (N = 1,003). The data provide strong support for the hypothesis that the effect of lifestyle risk is dependent on the strength or weakness of individual propensity, indicating that lifestyle risk has a stronger effect on delinquency for individuals with a high propensity to offend. The similarity of the results across two independent samples suggests the findings are stable.
Temperament: Measurement and Impact on Consumer Behavior

This article translates from Polish a measurement tool of temperament (Strelau and Zadawzki, 1993) and validates it in a French context. Through comparisons with personality traits, it explores its impact on certain purchasing behaviors. The article demonstrates the link between energetic (temporal) traits and purchasing behaviors that require great efforts (long-lasting efforts), although personality is linked either not at all or only slightly to these behaviors.
Deviant (M)others: The Construction of Teenage Motherhood in Contemporary Discourse

Paradoxically, the focus on teen motherhood as an object of concern in the West has coincided with declining rates of teen birth. This suggests that the view of teenage motherhood as problematic is underpinned by changing social and political imperatives regarding the role of women in these countries. This article examines the literature surrounding teenage motherhood from the United States, United Kingdom and New Zealand, and explores the way in which normative perceptions of motherhood have shifted over the past few decades to position teenage mothers as stigmatised and marginalised. Two specific discourses – those of welfare dependency and social exclusion – are highlighted, and their mediation through scientific discourses examined. The increasing trend to evidence-based policy development has masked the ideological basis of much policy in this area and highlights the importance of critical evaluation of the discourses surrounding teenage motherhood. A critical examination of the literature suggests that teenage mothers are vilified, not because the evidence of poor outcomes for teen mothers and their children is particularly compelling, but because these young women resist the typical life trajectory of their middle-class peers which conforms to the current governmental objectives of economic growth through higher education and increased female workforce participation.
Gravity duals of half-BPS Wilson loops

We explicitly construct the fully back-reacted half-BPS solutions in Type IIB supergravity which are dual to Wilson loops with 16 supersymmetries in = 4 super Yang-Mills. In a first part, we use the methods of a companion paper to derive the exact general solution of the half-BPS equations on the space AdS2 × S2 × S4 × Σ, with isometry group SO(2, 1) × SO(3) × SO(5) in terms of two locally harmonic functions on a Riemann surface Σ with boundary. These solutions, generally, have varying dilaton and axion, and non-vanishing 3-form fluxes. In a second part, we impose regularity and topology conditions. These non-singular solutions may be parametrized by a genus g ≥ 0 hyperelliptic surface Σ, all of whose branch points lie on the real line. Each genus g solution has only a single asymptotic AdS5 × S5 region, but exhibits g homology 3-spheres, and an extra g homology 5-spheres, carrying respectively RR 3-form and RR 5-form charges. For genus 0, we recover AdS5 × S5 with 3 free parameters, while for genus g ≥ 1, the solution has 2g+5 free parameters. The genus 1 case is studied in detail. Numerical analysis is used to show that the solutions are regular throughout the g = 1 parameter space. Collapse of a branch cut on Σ subtending either a homology 3-sphere or a homology 5-sphere is non-singular and yields the genus g−1 solution. This behavior is precisely expected of a proper dual to a Wilson loop in gauge theory.
Attachment styles, grief responses, and the moderating role of coping strategies in parents bereaved by the Sewol ferry accident

ABSTRACT Background: Previous studies on the influence of different types of attachment on grief responses have yielded contradictory outcomes. Little research has been conducted to identify the psychological processes that moderate the relationship between attachment representations and patterns of grief in disaster-related grief. Objective: The present study examines the effects of different attachment types on the grief responses of parents bereaved by loss of a child in a ferry accident, along with the moderating role of coping strategies. Methods: Bereaved parents (n = 81) completed self-report questionnaires evaluating attachment, coping strategies, complicated grief, and shame/guilt. We performed correlational analyses to examine the associations among variables. We also conducted hierarchical regression analyses and simple slope analyses to examine the moderation effects of coping strategies. Results: Anxious attachment was associated with severe shame/guilt, and avoidant attachment correlated with complicated grief. Anxious attachment was positively associated with all types of coping strategies, and avoidant attachment was negatively related to problem- and emotion-focused coping. The use of problem-focused coping strategies was a significant moderator of the relationship between the avoidant attachment dimension and shame/guilt. Avoidant attachment had a significant effect on shame/guilt in groups with a high level of problem-focused coping. In contrast, none of the coping strategies significantly moderated the relationship between anxious attachment and grief response. Conclusions: The results suggest that people with highly avoidant attachment might be overwhelmed by shame and guilt when they try to use problem-focused coping strategies. This finding suggests that grief interventions should be organized with consideration of individual differences in attachment representations.
Many-to-One Throughput Capacity of IEEE 802.11 Multihop Wireless Networks

This paper investigates the many-to-one throughput capacity (and by symmetry, one-to-many throughput capacity) of IEEE 802.11 multihop networks, in which many sources send data to a sink. An example of a practical scenario is that of a multihop mesh network connecting source and relay nodes to an Internet gateway. In the trivial case where all source nodes are just one hop from the sink, the system throughput can approach Ls, where Ls is the throughput capacity of an isolated link consisting of just one transmitter and one receiver. In the nontrivial case where some source nodes are more than one hop away, one can still achieve a system throughput of Ls by sacrificing and starving the non-one-hop source nodes-however, this degenerates to an unacceptable trivial solution. We could approach the problem by the following partitioning: preallocate some link capacity aLs (0 les a les 1) at the sink to the one-hop source nodes and then determine the throughput for the source nodes that are two or more hops away based on the remaining capacity L = (1 - a)Ls. The throughput of the one-hop nodes will be around aLs. This paper investigates the extent to which the remaining capacity L can be used efficiently by the source traffic that is two or more hops away. We find that for such source traffic, a throughput of L is not achievable under 802.11. We introduce the notion of "canonical networks,rdquo a general class of regularly structured networks that allow us to investigate the system throughput by varying the distances between nodes and other operating parameters. When all links have equal length, we show that 2L/3 is the upper bound for general networks, including random topologies and canonical networks. When the links are allowed to have different lengths, we show that the throughput capacity of canonical networks has an analytical upper bound of 3L/4. The tightness of the bound is confirmed by simulations of 802.11 canonical networks, in which we obtain simulated throughputs of 0.74L when the source nodes are two hops away and 0.69L when the source nodes are many hops away. We conjecture that 3L/4 is also the upper bound for general networks. Our simulations show that 802.11 networks with random topologies operated with AODV routing typically achieve throughputs far below 3L/4. Fortunately, by properly selecting routes near the gateway (or by properly positioning the relay nodes leading to the gateway) to fashion after the structure of canonical networks, the throughput can be improved by more than 150 percent: indeed, in a dense network, deactivating some of the relay nodes near the sink can lead to a higher throughput.
A study of epidemiology, risk factors and preventive measures against snake bites.

The epidemiology and exposing causes of snake bites were studied in 274 patients between 1 January 1982 and 30 December 1990. They comprised 142 males (51.82%) and 132 females (48.18%). Their ages ranged from 1 month to 86 years old. The age group most frequently bitten found in this study was between 15 to 29 years old amounting to 106 cases (38.69%). Of those 274 cases, 212 (77.37%) were the victims of poisonous snakes, namely, the green pit viper (Trimeresurus spp.) 156 cases (73.58%), the cobra (Naja naja) 53 cases (25.00%), Russell's viper (Vipera russellii siamensis) 3 cases (1.42%), while 13 cases (4.74%) were bitten by non-poisonous snakes, and in the remaining 49 cases (17.88%), the biting snakes were not clearly seen. It was found that 56 cases (20.44%) were bitten in the house, 50 cases (18.25%) were bitten within the precincts of the residence. However the highest number, 168 cases (61.31%) were bitten outside. It was also interesting to learn that 221 cases (80.66%) out of 274 were bitten in Bangkok, 91 cases (33.21%) were bitten from 6.00 p.m. to 9.00 p.m. , 129 cases (47.08%) were bitten between June and September, 98 cases (35.77%) were bitten on a foot and 77 cases (28.10%) were bitten on a finger. The high risk factor of being bitten by a snake was walking along a farm or a ranch with masses of grass or undergrowth during the night without self-prevention and good caution. Therefore, health education on preventive measures were elucidated.
Convenient Categories of Smooth Spaces

A "Chen space" is a set X equipped with a collection of "plots" - maps from convex sets to X - satisfying three simple axioms. While an individual Chen space can be much worse than a smooth manifold, the category of all Chen spaces is much better behaved than the category of smooth manifolds. For example, any subspace or quotient space of a Chen space is a Chen space, and the space of smooth maps between Chen spaces is again a Chen space. Souriau's "diffeological spaces" share these convenient properties. Here we give a unified treatment of both formalisms. Following ideas of Dubuc, we show that Chen spaces, diffeological spaces, and even simplicial complexes are examples of "concrete sheaves on a concrete site". As a result, the categories of such spaces are locally cartesian closed, with all limits, all colimits, and a weak subobject classifier. For the benefit of differential geometers, our treatment explains most of the category theory we use.
Self-concept clarity: Measurement, personality correlates, and cultural boundaries.

Self-concept clarity (SCC) references a structural aspect oftbe self-concept: the extent to which selfbeliefs are clearly and confidently defined, internally consistent, and stable. This article reports the SCC Scale and examines (a) its correlations with self-esteem (SE), the Big Five dimensions, and self-focused attention (Study l ); (b) its criterion validity (Study 2); and (c) its cultural boundaries (Study 3 ). Low SCC was independently associated with high Neuroticism, low SE, low Conscientiousness, low Agreeableness, chronic self-analysis, low internal state awareness, and a ruminative form of self-focused attention. The SCC Scale predicted unique variance in 2 external criteria: the stability and consistency of self-descriptions. Consistent with theory on Eastern and Western selfconstruals, Japanese participants exhibited lower levels of SCC and lower correlations between SCC and SE than did Canadian participants.
Parents of Children with Autism using an Email Group: A Grounded Theory Study

Parents of children with autism have difficulties obtaining adequate information and support to guide them in the care of their children. However, the growth of communication technologies such as email has created greater opportunities for accessing such resources. This article presents a grounded theory analysis of the messages sent to an email group by parents of children with autism. The core category emerging from the analysis indicates that the group functioned in making sense of autism. The core category comprises four categories: searching for meaning; adjusting to changes; providing support and encouragement; and narrative sharing of experiences. Although email groups function as a social support mechanism, we suggest that this is not the only legitimate function: such groups may contribute towards the development of parental representations of autism.
Too Much of a Good Thing or the more the Merrier?

Organizations are increasingly relying on informal leaders within teams to positively affect team outcomes. Also, as the percentage of women in the workforce grows, women are likely to shoulder more of the informal leadership responsibility within teams. This study explores the relationship of team performance and team cohesion to informal leadership dispersion and the gender composition of the informal leadership core within 21 intact manufacturing teams. The results indicate that informal leadership dispersion (the number of perceived informal leaders divided by team size) is positively related to team cohesion. In addition, when females compose a larger portion of the informal leadership core, supervisors’ratings of team performance are higher.
Real‐time identification of liver cancers by using indocyanine green fluorescent imaging

We have often encountered difficulties in identifying small liver cancers during surgery. Fluorescent imaging using indocyanine green (ICG) has the potential to detect liver cancers through the visualization of the disordered biliary excretion of ICG in cancer tissues and noncancerous liver tissues compressed by the tumor.
