Published: February 2014

SummaryThe choice of approach for diagnosing temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDR), viz. functional examination or TMJ imaging, is debatable and complicated by findings of low agreement between these approaches. Our aim was to investigate the validity of functional ADDR diagnostics using clinical examination and opto‐electronic mandibular movement recordings versus magnetic resonance imaging (MRI). 53 participants (32 women and 21 men, mean age ± s.d. of 28·7 ± 10·1 years) underwent a clinical examination, mandibular movement recording and MRI of their TMJs within 1 month. All were performed and analysed in a single‐blind design by different experienced examiners for each technique. The sensitivity and specificity of each functional diagnostic method was calculated, with MRI as the gold standard. Anterior disc displacement with reduction was diagnosed in 27·6% of the TMJs clinically, in 15·2% using the movement recordings and in 44·8% on MRI. The specificity of the clinical examination for diagnosing ADDR was 81·0%, and of the movement recordings, 96·6%. The sensitivity was 38·3% and 29·8%, respectively. The chance of having a false‐positive functional diagnosis of ADDR compared with MRI is low, and disagreement between the functional methods and MRI is mainly due to the high number of MRI diagnoses in asymptomatic subjects. In view of the fact that ADDR becomes clinically relevant only when it interferes with TMJ function, the functional diagnostic approach can be considered benchmark in ADDR recognition.
How Does Price Presentation Influence Consumer Choice? The Case of Life Insurance Products
Authors: Huber Carin , Gatzert Nadine , Schmeiser Hato 
Published: February 2014

AbstractLife insurance is an important product for many individuals, both to protect dependents against the premature death of an income producer and to provide savings in later retirement years. These kinds of products, however, can be quite complex. Regulatory authorities and consumers currently ask for more cost transparency with respect to product components (e.g., risk premium for death benefits, savings premium, cost of investment guarantee) and administration costs. The aim of this article is to measure the effects of different forms of presenting the price of life insurance contract components and especially of embedded investment guarantees on consumer evaluation of those products. The intention is to understand the extent to which price presentation affects consumer demand. This is done by means of an experimental study and by focusing on unit‐linked life insurance products. Our findings reveal that contrary to other consumer products, there are no precise effects of “price bundling” and “price optic” on consumer evaluation and purchase intention in the case of life insurance. Consumer experience and price perception, however, yield a significant moderating effect.
Challenging the tyranny of the five‐paragraph essay: teachers and students as semiotic boundary workers in classroom and digital space
Authors: Schwartz Lisa H. 
Published: February 2014

AbstractThis article addresses several challenges faced by educators and students in English classrooms in the US–Mexico borderlands region that will resonate with educators more broadly. I present how Ms Smith, the predominately Latino students in her high school writing class and I moved beyond what Ms Smith called the “tyranny of the five‐paragraph essay” used for standardised tests so that students were able to make personally and academically meaningful arguments in their writing. I examine how we collaboratively mobilised interests, motivations and diverse semiotic resources across out‐of‐school and in‐school contexts in the process of developing multimodal and hybrid genres and texts. First, I describe how Ms Smith and I crafted hybrid, digitally mediated classroom spaces and essay assignments informed by students' identity and literacy practices within digital networks. Next, I examine how three Latina students used semiotic resources and issues circulating in the different spaces of their lives to confidently argue their perspectives within the hybrid genres we created. From this collaborative work, I suggest that thinking of students and teachers as “semiotic boundary workers” provides a useful framework for practitioners who want to enable young people to draw on their practices and digital tools and engage their expansive, networked and creative affordances in academic contexts.
Contrasting evolutionary trajectories of multiple retrotransposons following independent allopolyploidy in wild wheats
Authors: Senerchia Natacha , Felber François , Parisod Christian 
Published: February 2014

Summary

Transposable elements (TEs) are expectedly central to genome evolution. To assess the impact of TEs in driving genome turnover, we used allopolyploid genomes, showing considerable deviation from the predicted additivity of their diploid progenitors and thus having undergone major restructuring.

Genome survey sequencing was used to select 17 putatively active families of long terminal repeat retrotransposons. Genome‐wide TE insertions were genotyped with sequence‐specific amplified polymorphism (SSAP) in diploid progenitors and their derived polyploids, and compared with changes in random sequences to assess restructuring of four independent Aegilops allotetraploid genomes.

Generally, TEs with different evolutionary trajectories from those of random sequences were identified. Thus, TEs presented family‐specific and species‐specific dynamics following polyploidy, as illustrated by Sabine showing proliferation in particular polyploids, but massive elimination in others. Contrasting with that, only a few families (BARE1 and Romani) showed proliferation in all polyploids. Overall, TE divergence between progenitors was strongly correlated with the degree of restructuring in polyploid TE fractions.

TE families present evolutionary trajectories that are decoupled from genome‐wide changes after allopolyploidy and have a pervasive impact on their restructuring.
MODELING AND ANALYSIS OF THE DEPLETION OF ORGANIC POLLUTANTS BY BACTERIA WITH EXPLICIT DEPENDENCE ON DISSOLVED OXYGEN

AbstractIn this paper, a nonlinear mathematical model is proposed and analyzed to study the depletion of dissolved oxygen caused by interactions of organic pollutants with bacteria in a water body, such as lake. The system is assumed to be governed by three dependent variables, namely, the cumulative concentration of organic pollutants, the density of bacteria and the concentration of dissolved oxygen. In the model, the coefficient of interaction of organic pollutants with bacteria depends upon the concentration of dissolved oxygen nonlinearly and explicitly, which is the main focus of this paper, has never been studied before. The stability theory of differential equations is used to analyze the model and to confirm the analytical results numerical simulation is performed. The model analysis shows that if the coefficient of interaction mentioned above depends upon dissolved oxygen explicitly, the decrease in its concentration is more than the case when the interaction does not depend on dissolved oxygen and consequently the depletion of organic pollutants is also more in such a case.

AbstractFlooding events negatively affect plant performance and survival. Flooding gradients thereby determine the dynamics in vegetation composition and species abundance. In adaptation to flooding, the group VII Ethylene Response Factor genes (ERF‐VIIs) play pivotal roles in rice and Arabidopsis through regulation of anaerobic gene expression and antithetical survival strategies. We investigated if ERF‐VIIs have a similar role in mediating survival strategies in eudicot species from flood‐prone environments. Here, we studied the evolutionary origin and regulation of ERF‐VII transcript abundance and the physiological responses in species from two genera of divergent taxonomic lineages (Rumex and Rorippa). Synteny analysis revealed that angiosperm ERF‐VIIs arose from two ancestral loci and that subsequent diversification and duplication led to the present ERF‐VII variation. We propose that subtle variation in the regulation of ERF‐VII transcript abundance could explain variation in tolerance among Rorippa species. In Rumex, the main difference in flood tolerance correlated with the genetic variation in ERF‐VII genes. Large transcriptional differences were found by comparing the two genera: darkness and dark submergence‐induced Rumex ERF‐VIIs, whereas HRE2 expression was increased in submerged Rorippa roots. We conclude that the involvement of ERF‐VIIs in flooding tolerance developed in a phylogenetic‐dependent manner, with subtle variations within taxonomic clades.

Relationships among fourteen species of Satureja growing wild in Iran detected with molecular markers
Authors: Hadian J. , Khadivi‐Khub A. 
Published: February 2014

AbstractThe genus Satureja is an important plant with a number of aromatic and medicinal properties. In this research, the relative efficiencies of amplified fragment length polymorphism (AFLP) and selectively amplified microsatellite polymorphic loci (SAMPL) were used to detect genetic relationships among 14 species of Satureja, growing wild in Iran. Eleven AFLP and 14 SAMPL primer combinations produced 999 and 1142 scorable bands, respectively, all of the fragments of which were found to be polymorphic. The average genetic similarity values based on Jaccard's coefficient were 0.24 and 0.21 for AFLP and SAMPL, respectively, indicating considerable distance and diversity in the studied germplasm. The correlation coefficients were statistically significant between both marker systems (r = 0.89). UPGMA derived from the combined binary data matrices of both markers depicted genetic distinctions among the studied species and clustered them into two main clusters and several groups. S. edmondi showed the maximum distance from other species and was placed into a single main cluster, while the maximum similarity was obtained between S. rechingeri and S. khuzistanica. Our results indicate that both marker systems are suitable for differentiating individuals and species of this genus.

AbstractBackgroundRecent studies suggest that a Mediterranean dietary pattern during pregnancy may influence pregnancy outcomes. The aim of this study was to evaluate the effect of adherence to a Mediterranean diet (MD) during pregnancy on fetal growth restriction (FGR) and preterm delivery (PTD) in a French Caribbean island where the population is largely of African descent and presents dietary patterns similar to MD.MethodsUsing data from the TIMOUN Mother–Child Cohort Study conducted in Guadeloupe (French West Indies) between 2004 and 2007, we analysed data for 728 pregnant women who delivered liveborn singletons without any major congenital malformations. Degree of adherence to MD during pregnancy was evaluated with a semi‐quantitative food frequency questionnaire based on nine dietary criteria. Multiple logistic regression models were used to analyse birth outcomes while taking potential confounders into account.ResultsOverall there was no association between MD adherence during pregnancy and the risk of PTD or FGR. However, pre‐pregnancy body mass index was a strong effect modifier, and MD adherence was associated with a decreased risk of PTD specifically in overweight and obese women (adjusted odds ratio 0.7, 95% confidence interval 0.6, 0.9) (P heterogeneity <0.01).ConclusionsThese results suggest that Caribbean diet during pregnancy may carry some benefits of MD and may contribute to reduce the risk of PTD in overweight and obese pregnant women.

ObjectiveTo evaluate the effects of phacoemulsification with different fluidic parameters on the intraocular tissues using contrast‐enhanced magnetic resonance imaging (CE‐MRI).ProceduresPhacoemulsification with intraocular lens (IOL) implantation was performed on 10 pairs of enucleated canine eyes. Irrigation fluid containing dilutedMRIcontrast agent was used, with the bottle height/the vacuum pressure set at 50 cm/80 mmHg for one eye (Group L) and at 120 cm/150 mmHg for the opposite eye (Group H).CE‐MRIwas carried out immediately after phacoemulsification to evaluate the presence of anterior hyaloid membrane detachment (AHD) and the leakage volume‐to‐vitreous volume ratio (LV/VV%). The ultrasound time, the volume of irrigation solution used, and the total irrigation time were recorded.ResultsAHDwas seen in seven of the 10 eyes in Group L and in nine of the 10 eyes in Group H. Fluid leakage into the vitreous humor (LV/VV%) was significantly greater in Group H than in Group L (P < 0.01). TheLV/VV% was also correlated with the total irrigation time in both groups (P < 0.05). The volume of irrigation solution used in Group H was significantly greater than that used in Group L (P < 0.001). There was no statistically significant difference in the ultrasound time between the two groups.ConclusionsLow fluidic parameters led to decreased fluid passage through the zonules, reducing fluid passage into the vitreous. These may also lead to reduced surgical stress on the intraocular tissues by decreasing the amount of irrigation solution used during phacoemulsification in the dog.
Integrated Systems-Based Approach to Monitoring Environmental Remediation

Published: February 2014

The U.S. Department of Energy is responsible for risk reduction and cleanup of its nuclear weapons complex. Remediation strategies for some of the contamination may include techniques that mitigate risk, but leave contaminants in place. Monitoring to verify remedy performance and long-term mitigation of risk is key to implementing these strategies and can be a large portion of the total cost of remedy implementation. Especially in these situations, there is a need for innovative monitoring approaches that move away from the cost- and labor-intensive point-source monitoring. In this paper, alternative approaches for monitoring are presented for vadose zone, groundwater, groundwater/surface water interface, and surface water.
To illustrate integrated, systems-based monitoring, this paper focuses on vadose zone contaminant remediation to mitigate impact to groundwater. In this context, vadose zone contamination is a source, or potential source, to groundwater plumes. The monitoring design uses a systems-based approach focused on developing a conceptual site model that highlights key features that control contaminant flux to groundwater. These features are derived considering the unsaturated flow and contaminant transport processes in the vadose zone and the nature of the waste discharge. Diagnostic properties and/or parameters related to both short- and long-term contaminant flux to groundwater can be identified and targeted for monitoring. The resolution of monitoring data needed to correspond to a functionally useful indicator of flux to groundwater can be estimated using quantitative analyses and the associated unsaturated flow properties relevant to the targeted site and vadose zone features. This monitoring design approach follows the process of developing a quantitative conceptual model suitable for supporting projections of future flux to groundwater. Support for such projections is important because it is likely that, in many cases, remediation decisions for the vadose zone will need to be made based all or in part on projected impacts to groundwater, and monitoring will then be applied to verify that remedy goals are being met.
The Regulatory Framework for Safe Decommissioning of Nuclear Power Plants in Korea

Published: February 2014

We are having 23 units of nuclear power plants in operation and 5 units of nuclear power plants under construction in Korea as of September 2012. However, we don’t have any experience on shutdown permanently and decommissioning of nuclear power plants. There are only two research reactors being decommissioned since 1997. It is realized that improvement of the regulatory framework for decommissioning of nuclear facilities has been emphasized constantly from the point of view of IAEA’s safety standards. It is also known that IAEA will prepare the safety requirement on decommissioning of facilities; its title is the Safe Decommissioning of Facilities, General Safety Requirement Part 6.
According to the result of IAEA’s Integrated Regulatory Review Service (IRRS) mission to Korea in 2011, it was recommended that the regulatory framework should require decommissioning plans for nuclear installations to be constructed and operated and these plans should be updated periodically. In addition, after the Fukushima nuclear disaster in Japan in March of 2011, preparedness for early decommissioning caused by an unexpected severe accident became important issues and concerns.
In this respect, it is acknowledged that the regulatory framework for decommissioning of nuclear facilities in Korea need to be improved. First of all, we focus on identifying the current status and relevant issues of regulatory framework for decommissioning of nuclear power plants compared to the IAEA’s safety standards in order to achieve our goal. And then the plan is established for improvement of regulatory framework for decommissioning of nuclear power plants in Korea. It is expected that if the things will go forward as planned, the revised regulatory framework for decommissioning could enhance the safety regime on the decommissioning of nuclear power plants in Korea in light of international standards.
A Matrix-Inversion Method for Gamma-Source Mapping From Gamma-Count Data
Authors: Adsley Ian , Bull Richard K. , Burgess Claire 
Published: February 2014

In a previous paper (1) it was proposed that a simple matrix inversion method could be used to extract source distributions from gamma-count maps, using simple models to calculate the response matrix. The method was tested using numerically generated count maps.
In the present work a 100 kBq Co60 source has been placed on a gridded surface and the count rate measured using a NaI scintillation detector. The resulting map of gamma counts was used as input to the matrix inversion procedure and the source position recovered. A multisource array was simulated by superposition of several single-source count maps and the source distribution was again recovered using matrix inversion. The measurements were performed for several detector heights. The effects of uncertainties in source-detector distances on the matrix-inversion method are also examined.
The results from this work give confidence in the application of the method to practical applications, such as the segregation of highly active objects amongst fuel-element debris.

BELGONUCLEAIRE has been operating the Dessel MOX plant at an industrial scale between 1986 and 2006. During this period, 40 metric tons of plutonium (HM) have been processed into 90 reloads of MOX fuel for commercial light water reactors. The decision to stop the production in 2006 and to decommission the MOX plant was the result of the shrinkage of the MOX fuel market due to political and commercial factors.
As a significant part of the decommissioning project of the Dessel MOX plant, about 170 medium-sized glove-boxes and about 1.200 metric tons of structure and equipment outside the glove-boxes are planned for dismantling.
The license for the dismantling of the MOX plant was granted by Royal Decree in 2008 and the dismantling started in March 2009. The dismantling works are carried out by an integrated organization under leadership and responsibility of BELGONUCLEAIRE; this organization includes 3 main contractors, namely Tecnubel N.V., the THV (‘Tijdelijke HandelsVereniging’) Belgoprocess / SCK•CEN and Studsvik GmbH and TRACTEBEL ENGINEERING as project manager.
In this paper, after having described the main characteristics of the project, the authors review the different organizational and technical options considered for the decommissioning of the glove-boxes; thereafter the main decision criteria (qualification of personnel and of processes, confinement, cutting techniques & radiation protection, safety aspects, alpha-bearing waste management) are analyzed as well.
Finally the progress, the feedback and the lessons learned at the end of August 2013 are presented, giving the principal’s and contractors point of view.
