Experience and the unexpected: risk and mitigation issues for operating underground storage silos for coal-fired power plant

Observed autoignition events and extinguishing the resulting smouldering fires in an underground storage system of a coal-fired power plant have provided insight into the array of contributing variables, and some experience on quantifying the risk with alternative scenarios of event initiation, progress and potential mitigation. Although the first attempts to quantify the risk suggest high sensitivity to the sequence of action taken after fire alarm, and no similar storage sites really exist, some recommended preventive, corrective and other mitigating activities can be at least partly defined and improved by using the cumulative experience and parallel efforts in other closed or underground storage sites. However, there are also so-called black (or at least grey) swans: unexpected events for which the facility may be poorly prepared for. In the case of the underground storage silos, such an event was experienced when incoming cold coal during a harsh winter season froze the sewer system that normally protects the stored coal from seepage water. With blocked normal bypass, the seepage water found its way to the coal silos and created large clumps of icy coal that blocked the coal conveyors. Although freezing weather is not unusual at high-latitude power plants, the common methods to combat freezing of coal are mainly useful for open storage sites and above-ground transport. Options for mitigation are discussed, as well as the event chain leading to an event that had never previously occurred. The case is discussed from the point of view of options to prepare for rare or unforeseen events.
Galaxy Star Formation as a Function of Environment in the Early Data Release of the Sloan Digital Sky Survey

We present in this paper a detailed analysis of the effect of environment on the star formation activity of galaxies within the Early Data Release (EDR) of the Sloan Digital Sky Survey (SDSS). We have used the Hα emission line to derive the star formation rate (SFR) for each galaxy within a volume-limited sample of 8598 galaxies with 0.05 ≤ z ≤ 0.095 and M(r*) ≤ -20.45. We find that the SFR of galaxies is strongly correlated with the local (projected) galaxy density, and thus we present here a density-SFR relation that is analogous to the density-morphology relation. The effect of density on the SFR of galaxies is seen in three ways. First, the overall distribution of SFRs is shifted to lower values in dense environments compared with the field population. Second, the effect is most noticeable for the strongly star-forming galaxies (Hα EW > 5 Å) in the 75th percentile of the SFR distribution. Third, there is a "break" (or characteristic density) in the density-SFR relation at a local galaxy density of ~1 h Mpc-2. To understand this break further, we have studied the SFR of galaxies as a function of clustercentric radius from 17 clusters and groups objectively selected from the SDSS EDR data. The distribution of SFRs of cluster galaxies begins to change, compared with the field population, at a clustercentric radius of 3-4 virial radii (at the >1 σ statistical significance), which is consistent with the characteristic break in density that we observe in the density-SFR relation. This effect with clustercentric radius is again most noticeable for the most strongly star-forming galaxies. Our tests suggest that the density-morphology relation alone is unlikely to explain the density-SFR relation we observe. For example, we have used the (inverse) concentration index of SDSS galaxies to classify late-type galaxies and show that the distribution of the star-forming (EW Hα > 5 Å) late-type galaxies is different in dense regions (within 2 virial radii) compared with similar galaxies in the field. However, at present, we are unable to make definitive statements about the independence of the density-morphology and density-SFR relation. We have tested our work against potential systematic uncertainties including stellar absorption, reddening, SDSS survey strategy, SDSS analysis pipelines, and aperture bias. Our observations are in qualitative agreement with recent simulations of hierarchical galaxy formation that predict a decrease in the SFR of galaxies within the virial radius. Our results are in agreement with recent 2dF Galaxy Redshift Survey results as well as consistent with previous observations of a decrease in the SFR of galaxies in the cores of distant clusters. Taken together, these works demonstrate that the decrease in SFR of galaxies in dense environments is a universal phenomenon over a wide range in density (from 0.08 to 10 h Mpc -2) and redshift (out to z ≃ 0.5).
Explaining high attainment in faith schools: the impact of Religious Education and other examinations on pupils’ GCSE points scores

Faith schools are popular with parents and feature towards the top of the annual tables of school performance in England based on the government’s preferred measures of school outcomes. Academic studies suggest that although the observed differentials between the faith and non‐faith sectors at the end of Key Stage 4 are partly explicable in demographic and similar terms, they do nonetheless represent a real phenomenon. There is little research into the causes of this. The simplest hypothesis is that pupils attending faith schools take more examinations, thus boosting their average points scores. The possible additional courses are, by inference, in Religious Education. This study examines the hypothesis and finds it wanting as an adequate explanation. Further areas of research are suggested.
The Experiment Research of Neuroprotection of Hypoperfusion Postconditioning on Cerebral Ischemia

Abstract In this study, we tested the hypothesis that the alternating of hypoperfusion and full reperfusion (hypoperfusion postconditioning) could improve neuroprotection on cerebral ischemia in rats and explored the role of TAp63 and △Np63 in this process. Eighty male Sprague Dawley rats were randomly divided into 4 groups: the sham group, the cerebral ischemic/reperfusion group (I/R), the hypoperfusion group 1 (HR1), and the hypoperfusion group 2 (HR2). Cerebral ischemia was established by clamping the bilateral common carotid artery with hypotension for 20 minutes. For the rats in the HR1 group, the blood pressure was maintained to 80 to 90 mm Hg in clamping bilateral common carotid artery minutes and then unclamped. For the rats in the HR2 group, the clamping was performed at one side of the common carotid artery and one half of the other side of common carotid artery. Neurologic behavior scores in the I/R, HR1, and HR2 groups decreased significantly after cerebral ischemia, and scores in the HR2 group were significantly higher than those in the I/R group (P < 0.05). Neuronal densities in the HR1 and HR2 groups were significantly higher than that in the I/R group (P < 0.05). Neuronal apoptosis in the HR1 and HR2 groups was significantly lower than that inthe I/R group (P < 0.05). TAp63 and S100&bgr; concentration decreased, and △Np63 increased significantly in the HR1 and HR2 groups as compared with the I/R group (P < 0.05). No significant difference in these parameters between the HR1 and HR2 groups (P > 0.05). Alternating of hypoperfusion and normal perfusion postconditioning had neuroprotection function on cerebral ischemia in the rats. This could relate with decreasing expression of TAp63 and increasing expression of △Np63 in hippocampal region of the first area in the hippocampal circuit to inhibit neuronal apoptosis.
Increased Sensitivity of Sars-Coronavirus to a Combination of Human Type I and Type II Interferons

There is currently an urgent need to identify effective antiviral agents that will prevent and treat severe acute respiratory syndrome coronavirus (SARS-CoV) infection. In this study, we have investigated and compared the antiviral effect of different interferons (IFNs) on SARS-CoV replication in the epithelial kidney monkey Vero cell line. The results showed that SARS-CoV grown in Vero cells is moderately sensitive to IFN-β and only weakly sensitive to IFN-α and IFN-γ, in comparison to other IFN-sensitive viruses, such as those for encephalomyocarditis, vesicular stomatitis and Newcastle disease. Simultaneous incubation of Vero cells with IFN-β and IFN-γ indicated that they may act synergistically against SARS-CoV replication. The IFN-induced MxA protein was detected in the IFN-treated Vero cells. The data, however, suggest that the antiviral activity of IFN against SARS-CoV virus is independent of MxA expression.
Detecting Sentencing Disparity: Some Problems and Evidence

Research has yet to establish convincingly either the existence or the absence of sentencing discrimination. This paper identifies major methodological and conceptual problems inherent in sentencing disparity research and presents and empirical analysis of the racial disparity argument for the years 1969, 1973, and 1977. Evidence is presented that indicates (1) sentencing patterns fluctuate with contextual variation, (2) racial discrimination at the sentencing stage exists, and (3) the detection of sentencing discrimination can easily be obscurred by a number of pitfalls
A first step to the evaluation of SimGrid in the context of a real application

Simulation is a ¿simple¿ method to experimentally evaluate the behavior of algorithms designed for parallel and distributed platforms. Moreover, the reliability of the evaluation strongly depends on the models used inside the simulator. This paper is devoted to the study and the evaluation of the behavior of the SimGrid simulator through a comparison between a simulated and a real execution of the same target application (i.e. heat propagation). Our target platforms are heterogeneous and their characteristics may dynamically vary during the execution. The obtained results (on a set of various platforms) show that the behavior observed when using the simulated platform is very close to the one obtained on the real one.
The Influence of Relationship Conflict and Trust on the Transactive Memory

Recent research on top management teams examines the effects of team processes on performance. This study attempts to add to this literature by examining how social political relations such as conflict and trust among members of a top management team moderate the performance effects of the team's cognitive processes, as represented by its transactive memory. The results indicate that the location dimension of transactive memory positively influences performance for teams with low levels of relationship conflict but has no significant effect for teams with high levels of relationship conflict.
Superior Visual Search Efficiency in High Trait Anxiety

Numerous studies have highlighted associations between self-report trait anxiety levels and impaired cognitive control (see e.g. Eysenck, Derakshan, Santos & Calvo, 2007). However, recent work has begun to also note associations between anxiety and visual perception, such as improved visual awareness for stimuli in high anxious individuals (Berggren, Blonievsky, & Derakshan, under review), as well as heightened ERP response on early visual components (e.g. Weymar, Keil, & Hamm, 2013). Notably, these effects occur not only for emotional stimuli but also affectively-neutral information. To test this account, we employed a feature versus conjunctive search task requiring participants to search through an array of letters for a target item, where efficient conjunctive search is known to require perceptual/attentional resources (Treisman & Gelade, 1980). Participants were pre-screened for high versus low levels of trait anxiety. As the set size of visual displays increased, we replicated the classic finding that featural search was relatively unaffected by increasing search difficulty, whereas conjunctive search was highly susceptible to the manipulation. Crucially, the high anxious group showed shallower increases in reaction times as set size increased for conjunctive search. This result suggests that high levels of anxiety are associated with superior visual search efficiency, implying that anxiety may influence perceptual processes as well as cognitive ones. We link this result to evidence of the amygdala enhancing perception through feedback connections with visual cortex (Amaral, Behniea, & Kelly, 2003); a network that may be bolstered by sustained experience of anxious mood.
The Historical Use of Radiotherapy in the Treatment of Sinus Infections

The aim of this paper is to assess the historical role of radiotherapy in the treatment of sinus infections. This assessment involved a literature-based review of how radiotherapy was used to treat sinus infections in the first half of the 20th century. Low doses of x-rays were used with considerable success to treat nearly 3,000 patients of sinus infection in a span of 12 years with these cases being reported in leading medical journals as case studies. The mechanism of x-ray induced reduction of inflammation and increased tissue repair is uncertain but appears to be related to the development of a multifactorial and integrative anti-inflammatory phenotype.
Proinflammatory Cytokines, Mood, and Sleep in Interepisode Bipolar Disorder and Insomnia: A Pilot Study With Implications for Psychosocial Interventions

Objective Proinflammatory cytokines are associated with bipolar disorder (BD), but less is known about how cytokines function during the interepisode period. This study examined cytokines, mood symptoms, and sleep in individuals with interepisode BD with complaints of insomnia. We also investigated the effects of a BD-specific modification of cognitive behavior therapy for insomnia (CBTI-BP) on cytokine levels. Methods Twenty-two adults with interepisode BD type I and insomnia were drawn from a subset of a National Institute of Mental Health funded study. Participants were randomly allocated to CBTI-BP (n = 11) or psychoeducation (n = 11). Participants completed a sleep diary, rated self-report measures of mania and depression, and provided samples assayed for interleukin (IL)-6 and tumor necrosis factor soluble receptor 2 (sTNF-R2). Results IL-6 was associated with mania symptoms (rs = 0.44, p = .041) and total sleep time (rs = −0.49, p = .026). IL-6 was related to depression symptoms at the trend level (rs = 0.43, p = .052). sTNF-R2 was not significantly related to mood or sleep measures. From pretreatment to posttreatment, CBTI-BP compared with psychoeducation was associated with a nonsignificant, large effect size decrease in IL-6 (z = −1.61, p = .13, d = −0.78) and a nonsignificant, small-medium effect size decrease in sTNF-R2 (z = −0.79, p = .44, d = −0.38). Conclusions These findings provide preliminary evidence that IL-6 is related to mania symptoms and shorter total sleep time in interepisode BD. A treatment that targets sleep in BD could potentially decrease IL-6 although replication is warranted.

Using growth curves to determine the timing of booster sessions

Booster sessions are often recommended to reestablish or reinforce the cognitive messages or behavior changes due to therapeutic and behavioral interventions. To plan intervention‐relevant booster sessions, researchers need to know the pattern(s) of individual change over time in outcome variables and for experimental groups. Growth curve analysis of repeated measures can estimate these patterns for different categories of intervention participants. This article demonstrates an application of this method using data from a recently completed multisite randomized experiment that compared 3 different counseling and testing methods for prevention of HIV infection and other sexually transmitted diseases, Project RESPECT. Reported self‐efficacy for condom use with the main sexual partner is used as an illustrative example. For most experimental groups, self‐efficacy for condom use declined for both female and male respondents soon after the intervention and booster sessions should have been instituted within 3 .
Prevalence, patterns and predictors of nursing care left undone in European hospitals: results from the multicountry cross-sectional RN4CAST study

Background Little is known of the extent to which nursing-care tasks are left undone as an international phenomenon. Aim The aim of this study is to describe the prevalence and patterns of nursing care left undone across European hospitals and explore its associations with nurse-related organisational factors. Methods Data were collected from 33 659 nurses in 488 hospitals across 12 European countries for a large multicountry cross-sectional study. Results Across European hospitals, the most frequent nursing care activities left undone included ‘Comfort/talk with patients’ (53%), ‘Developing or updating nursing care plans/care pathways’ (42%) and ‘Educating patients and families’ (41%). In hospitals with more favourable work environments (B=−2.19; p<0.0001), lower patient to nurse ratios (B=0.09; p<0.0001), and lower proportions of nurses carrying out non-nursing tasks frequently (B=2.18; p<0.0001), fewer nurses reported leaving nursing care undone. Conclusions Nursing care left undone was prevalent across all European countries and was associated with nurse-related organisational factors. We discovered similar patterns of nursing care left undone across a cross-section of European hospitals, suggesting that nurses develop informal task hierarchies to facilitate important patient-care decisions. Further research on the impact of nursing care left undone for patient outcomes and nurse well-being is required.
Relationships among attitudes about homework, amount of homework assigned and completed, and student achievement

Students (n = 709), parents, and teachers (n = 82) completed a questionnaire concerning amount of homework assigned by teachers, portion of assignments completed by students, and attitudes about homework. Student achievement measures were also collected. Weak relations were found between the amount of homework assigned and student achievement. Positive relations were found between the amount of homework students completed and achievement, especially at upper grades (6-12). At lower grades (2 and 4), teacher-assigned homework was related to negative student attitudes. At upper grades, teachers with more positive attitudes toward homework and those whose students performed more poorly on stantlardized tests reported assigning more homework. A path analysis for lower grades indicated that class grades were predicted only by standardized test scores and the proportion of homework completed by students. At upper grades, class grade predictors also included parent, teacher, and student attitudes.
Hong Kong Student Teachers' Personal Construction Of Teaching Efficacy

This study employed the repertory grid technique to investigate how a sample of 27 student teachers in Hong Kong developed a personal sense of teaching efficacy. The analysis indicated that the third year students' perceptions were more homogenous than were those of the first year students. The results also indicated that teaching efficacy was viewed in terms of the dimensions of concern for instructional participation and learning needs of pupils, communication and relationships with pupils, academic knowledge and teaching skills, lesson preparation, management of class discipline, teaching success, teaching commitment, and a sense of self-confidence. Experiences of teaching practice, electives, pupils, and teaching practice supervisors (Electives) were the major sources for the development of a sense of teaching efficacy. Implications of how those aspects of teacher training can be more effective in engendering a sense of efficacy in the student teachers are discussed.
Natural CMT2 Variation Is Associated With Genome-Wide Methylation Changes and Temperature Seasonality

As Arabidopsis thaliana has colonized a wide range of habitats across the world it is an attractive model for studying the genetic mechanisms underlying environmental adaptation. Here, we used public data from two collections of A. thaliana accessions to associate genetic variability at individual loci with differences in climates at the sampling sites. We use a novel method to screen the genome for plastic alleles that tolerate a broader climate range than the major allele. This approach reduces confounding with population structure and increases power compared to standard genome-wide association methods. Sixteen novel loci were found, including an association between Chromomethylase 2 (CMT2) and temperature seasonality where the genome-wide CHH methylation was different for the group of accessions carrying the plastic allele. Cmt2 mutants were shown to be more tolerant to heat-stress, suggesting genetic regulation of epigenetic modifications as a likely mechanism underlying natural adaptation to variable temperatures, potentially through differential allelic plasticity to temperature-stress. AUTHOR SUMMARY A central problem when studying adaptation to a new environment is the interplay between genetic variation and phenotypic plasticity. Arabidopsis thaliana has colonized a wide range of habitats across the world and it is therefore an attractive model for studying the genetic mechanisms underlying environmental adaptation. Here, we study two collections of A. thaliana accessions from across Eurasia to identify loci associated with differences in climates at the sampling sites. A new genome-wide association analysis method was developed to detect adaptive loci where the alleles tolerate different climate ranges. Sixteen novel such loci were found including a strong association between Chromomethylase 2 (CMT2) and temperature seasonality. The reference allele dominated in areas with less seasonal variability in temperature, and the alternative allele existed in both stable and variable regions. Our results thus link natural variation in CMT2 and epigenetic changes to temperature adaptation. We showed experimentally that plants with a defective CMT2 gene tolerate heat-stress better than plants with a functional gene. Together this strongly suggests a role for genetic regulation of epigenetic modifications in natural adaptation to temperature and illustrates the importance of re-analyses of existing data using new analytical methods to obtain deeper insights into the underlying biology from available data.
Media Selection and Managerial Characteristics in Organizational Communications

The media richness model and the symbolic interactionist perspective are the basis for hypotheses about managerial communication patterns. The hypothesized relationships are tested with data from 94 managers. The results indicate that managers tend to select the face-to-face medium for highly equivocal communications and written media for clear, objective communications. This relationship is stronger for managers with higher level positions and higher performance evaluations, and is not significantly affected by managerial educational level, organizational tenure, sender/receiver orientation, or introversion/extraversion. The implications of the findings for organization design, communications, and manager performance are discussed.
Sex and Academic Field in Relation to Birth Order and Achievement

This survey concerned the effect of sex and academic field on the well-documented relationship between birth order and achievement of 414 graduate students. No difference was found in the tendency for firstborn males (n = 240) and females (n = 174) to be high achievers. Academic field (science, n = 156; social studies, humanities, n = 208) also had no bearing on the relationship between birth order and achievement. The study did show a strong link between scholastic achievement and ordinal position which is consistent with past research.
