Published: February 2010

AbstractBackgroundA disintegrin and metalloprotease 12s (ADAM12s) is a potential first trimester serum marker for fetal trisomy and adverse pregnancy outcome in singletons. In this study, ADAM12s levels in first trimester serum of uncomplicated and complicated twins were evaluated.MethodsADAM12s was studied in maternal serum of 215 twin pregnancies, collected between 2004 and 2008. ADAM12s was measured ‘blind to outcome’ using AutoDelfia (PerkinElmer, Turku, Finland). As a reference, data from 2423 singletons were used.ResultsThe median ADAM12s level was increased in euploid twins [1.61 multiples of the median (MoM); n = 209] compared with singletons. The median ADAM12s MoM was significantly lower in monochorionic (1.36 MoM; n = 41) compared with dichorionic twins (1.67 MoM; n = 168) (Mann‐Whitney U test, p = 0.005). Trisomy 21 was identified in two pregnancies. Median ADAM12s MoM in twins complicated by hypertensive disorders (1.77 MoM, n = 35) or small for gestational age fetus (1.54 MoM; n = 24) was not significantly different from uncomplicated twins (1.64 MoM; n = 134).ConclusionMedian ADAM12s MoM in euploid twins was increased compared with singletons. Monochorionic had significantly lower median ADAM12s MoM than dichorionic twins. Median ADAM12s MoMs were not significantly different in twins complicated by hypertensive disorders or small for gestational age fetus compared with uncomplicated twins.

Published: February 2010

AbstractWe analyze the convergence of the spectrum of large random graphs to the spectrum of a limit infinite graph. We apply these results to graphs converging locally to trees and derive a new formula for the Stieltjes transform of the spectral measure of such graphs. We illustrate our results on the uniform regular graphs, Erdös‐Rényi graphs and graphs with a given degree sequence. We give examples of application for weighted graphs, bipartite graphs and the uniform spanning tree of n vertices. © 2010 Wiley Periodicals, Inc. Random Struct. Alg., 2010
A closer look at the internal corrosion test for automotive heat exchangers: the OY water test
Authors: Szala E. , Wainer M. , Vieregge K. 
Published: February 2010

AbstractNowadays, automotive heat exchangers are mainly made from aluminum. Over the last few decades, the development of aluminum brazing sheet has been mainly focused on the improvement of the external corrosion resistance. Recently, the interest of the heat exchanger manufacturers has also moved toward the assessment of the internal corrosion resistance. Accelerated tests are used to simulate in‐service conditions. These tests are crucial as they provide information to predict the material and product performance. Various internal corrosion tests have been developed, the so‐called ‘OY water tests’. Among all companies, the testing parameters can be varied in terms of ion concentrations or pH. Although the OY water tests are constantly being improved, there is so far no common internal corrosion standard as existing for external corrosion assessment. The present work aims at providing better understanding corrosion mechanisms encountered in the OY water media. The role of various elements present in the solution, cupric, chloride, sulfate ions, has been determined. These parameters were assessed via immersion testing. In order to get better understanding of the corrosion mechanism, electrochemical analysis combined with SEM characterization was carried out. The electrochemical analysis enables the understanding of the thermodynamics and kinetics of the corrosion process while immersion tests are performed to quantify the level of corrosion and follow the surface evolution over time.

Published: February 2010

AbstractBiological apatite (AP) is the main component of human bones, and it is a highly bioactive and biocompatible inorganic material. However, it has insufficient mechanical parameters and adhesion to surfaces. Carbon‐based coatings, such as diamond‐like carbon, carbon nanotubes and amorphous carbon are found to significantly improve the mechanical properties of AP, increase its adhesion, prevent metal ion release from metal implants and inhibit the formation of fibrous tissue and blood clotting upon implantation.In this study, nanodiamond (ND)‐reinforced AP composite coating was prepared by electrodeposition on austenitic stainless steel from simulated body fluid (SBF) containing ND particles. Results revealed the formation of dense and homogeneous AP coating, containing CO3 and HPO4 groups similar to the biological AP. The composite coating was characterized by ductility, improved hardness and adhesion to the steel surface in comparison to pure AP. Mineralization experiment in a simulated body fluid revealed that the composite coating is potentially biologically active. Copyright © 2010 John Wiley & Sons, Ltd.
Blessures dans la filiation et infertilité masculine : étude comparative et psychodynamique
Authors: Jaoul M. , Albert M. , Bailly M. , Selva J. , Molina Gomes D. 
Published: February 2010

Résumé
Cette recherche est née de la constatation clinique, à travers les récits de vie d’hommes infertiles, de l’existence de perturbations dans leur filiation. Dans un premier temps, il s’agira de déterminer, à l’aide d’une grille de filiation construite à partir d’une clinique psychanalytique, si, pour certains de ces hommes infertiles, le projet de devenir père pourrait être entravé par leur difficulté à se situer dans leur généalogie et à s’identifier à leur propre père. La comparaison d’un groupe de 30 hommes infertiles avec un groupe de 30 hommes fertiles permet de mettre en évidence l’impact de certains événements dans la filiation sur la capacité à procréer. Le second temps de la recherche sera consacré à une approche psychodynamique qui tentera d’éclairer l’hypothèse d’un lien entre l’impact traumatique de ces événements sur les sujets et sa traduction dans une expression somatique.
Le deuil de la fertilité dans l’insémination avec sperme de donneur (IAD)
Authors: Mazzone J.-C. 
Published: February 2010

Résumé
La pratique de l’IAD suscite paradoxalement chez l’homme stérile un blocage du deuil de sa fertilité. La mise en secret de la conception de l’enfant en est le symptôme. L’aide psychologique nécessaire à l’élaboration du deuil permettra la levée de ce secret, mais cela n’est pas suffisant pour l’accès de cet homme à la paternité. Il devra, en se reconnaissant actif et concepteur de son enfant, s’affronter à l’homosexualité latente inhérente à la pratique de l’IAD. Le travail de deuil mené à son terme verra l’homme stérile devenir un père authentique et serein.
A Review and Illustration of Contemporary Percutaneous Nephrolithotomy Practice Using Intracorporeal Techniques through Single Punctures for Complex Stone Burden in a UK Tertiary Referral Centre
Authors: Heer Rakesh , Veeratterapillay Rajan , Haslam Philip , Hasan S. Tahseen 
Published: February 2010

Objective: The treatment of complex renal stones remains challenging for surgeons using percutaneous nephrolithotomy (PCNL). A number of contemporary accessory techniques can help improve stone clearance allowing a reduction of multiple punctures and morbidity. We report our experience using a single puncture for complex stone cases. Patients and methods: We reviewed the practice of single puncture for complex stones (partial staghorns involving multiple calyces and complete staghorns) in our Institute from 2004 to 2007. These cases included paediatric patients who would otherwise typically endure open nephrolithotomy. Stone clearance, by intra-operative renoscopy and post-operative KUB, and requirement for ancillary procedures was assessed. Results: In total 35 complex stone cases were identified that matched the inclusion criteria (4 children). All patients were treated with a solitary puncture and two cases were abandoned due to excessive bleeding at the time of percutaneous access. Of the 33/35 cases that progressed fluoroscopic stone clearance was achieved. Case-based illustrations are presented showing accessory techniques such as intracorporeal catheters, flexible cystoscopy, basketing, lasering and percutaneous needle manipulations that facilitated these results. Conclusions: In cases of complex renal stone disease, the use of contemporary PCNL techniques can allow significant stone clearance through a single puncture in most cases. A team approach with intervention radiologists is emphasized.
Peripartum hysterectomy: An evolving picture
Authors: Turner Michael J. 
Published: February 2010

AbstractPeripartum hysterectomy (PH) is one of the obstetric catastrophes. Evidence is emerging that the role of PH in modern obstetrics is evolving. Improving management of postpartum hemorrhage and newer surgical techniques should decrease PH for uterine atony. Rising levels of repeat elective cesarean deliveries should decrease PH following uterine scar rupture in labor. Increasing cesarean rates, however, have led to an increase in the number of PHs for morbidly adherent placenta. In the case of uterine atony or rupture where PH is required, a subtotal PH is often sufficient. In the case of pathological placental localization involving the cervix, however, a total hysterectomy is required. Furthermore, the involvement of other pelvic structures may prospectively make the diagnosis difficult and the surgery challenging. If resources permit, PH for pathological placental localization merits a multidisciplinary approach. Despite advances in clinical practice, it is likely that peripartum hysterectomy will be more challenging for obstetricians in the future.
Kant's Political Religion: The Transparency of Perpetual Peace and the Highest Good
Authors: Taylor Robert S. 
Published: February 2010

AbstractScholars have long debated the relationship between Kant's doctrine of right and his doctrine of virtue (including his moral religion or ethico-theology), which are the two branches of his moral philosophy. This article will examine the intimate connection in his practical philosophy between perpetual peace and the highest good, between political and ethico-religious communities, and between the types of transparency peculiar to each. It will show how domestic and international right provides a framework for the development of ethical communities, including a kingdom of ends and even the noumenal ethical community of an afterlife, and how the transparency and trust achieved in these communities are anticipated in rightful political society by publicity and the mutual confidence among citizens that it engenders. Finally, it will explore the implications of this synthesis of Kant's political and religious philosophies for contemporary Kantian political theories, especially those of Jürgen Habermas and John Rawls.
“Bare Life” and Politics in Agamben's Reading of Aristotle
Authors: Finlayson James Gordon 
Published: February 2010

AbstractGiorgio Agamben's critique of Western politics inHomo Sacerand three related books has been highly influential in the humanities and social sciences. The critical social theory set out in these works depends essentially on his reading of Aristotle'sPolitics. His diagnosis of what ails Western politics and his suggested remedy advert to a “biopolitical paradigm,” at the center of which stand a notion of “bare life” and a purported opposition betweenbiosandzoē. Agamben claims that this distinction is found in Aristotle's text, in ancient Greek, and in a tradition of political theory and political society stemming from fourth-century Athens to the present. However, a close reading of Aristotle refutes this assertion. There is no such distinction. I show that he bases this view on claims about Aristotle by Arendt and Foucault, which are also unfounded.
Constitutions, EU Law and Judicial Strategies in the Czech Republic, Hungary and Poland

Published: February 2010

AbstractGiven far-reaching changes in the legal systems of East Central Europe since the mid-1990s, one might expect administrative court judges to have modified the way in which they decide cases, in particular by embracing less formalistic adjudication strategies. Relying on an original dataset of over one thousand business-related cases from the Czech Republic, Hungary and Poland, this article shows that – despite some variation across countries and time – judges have largely failed to respond to the incentives contained in the new constitutional frameworks. They continue to adopt the most-locally-applicable-rule approach and are reluctant to apply general principles of law or to rely on Dworkinian ‘policies’ in deciding hard cases. The analysis links these weak institutional effects to the role of constitutional courts, case overload and educational legacies.

AbstractIntroduction:Health professionals have a duty of care to radiotherapy patients in providing them with adequate information before treatment. There is a lack of research that describes the roles of radiation therapists and radiation oncology nurses in providing information to patients. This study aimed to: (1) explore how radiation therapists communicate with breast cancer patients during a radiotherapy planning appointment; (2) determine what information is provided during this appointment and (3) explore radiation therapists’ perspectives on their role in providing patient information and support.Methods:The following methodologies were used: self-report questionnaires; simulated radiotherapy planning sessions and joint interpretive forums. Statistical analysis was used to analyse the questionnaires and the simulated planning sessions and forums were analysed qualitatively.Results:A total of 110 radiation therapists participated in the survey. We simulated two radiotherapy planning appointments and held two forums. Four themes emerged: role definitions, reducing patient anxiety and distress, barriers and strategies for effective communication and confidence in patient communication.Conclusion:Radiation therapists play an important role in communicating with patients and providing information, particularly if patients exhibit anxiety and distress. Further research is required to determine whether patients’ information needs can be met with additional information provided by radiation therapists.
Comparing plaque brachytherapy and proton therapy for choroidal melanoma: a review of the literature
Authors: Appleton Jeremy P. , Bridge Peter 
Published: February 2010

AbstractThe aims of conservative treatment in patients with ocular melanoma are globe retention, good visual acuity (VA) and local control. Two well-established radiation conservative treatment options are proton beam radiotherapy and episcleral plaque brachytherapy (EPB). Patients who receive treatment with either of these options will experience some degree of radiation-related ocular complications and poor VA. The purpose of this review of the literature is to establish whether there is a significant clinical difference in normal tissue morbidity and local tumour control between proton therapy and EPB, and whether this difference can justify the purchase and implementation of additional proton therapy facilities. Based on this review, evidence suggested that both treatment options are comparable, and that neither proton therapy nor EPB is clinically superior than the other regarding normal tissue morbidity and local tumour control. This review highlighted the need for further research on a larger scale in order to bridge the gap that is apparent within the literature.

Published: February 2010

AbstractThe essential need for postoperative irradiation in people with carcinoma of the upper aerodigestive tract and limited metastatic nodal spread is controversial. An experience with postoperative radiotherapy in head and neck cancer (HNC) patients with one histologically positive cervical node is presented. Between 1976 and 2000, 37 individuals with confirmed metastatic disease in a single neck node underwent postoperative radiotherapy. The median follow-up period was 24 months. Among the 35 evaluable patients, the observed failure rates at the primary site, neck and distant location were 11%, 15% and 6%, respectively. The overall 5-year relapse-free survival rate was 60%. The relapse-free survival rate at 5 years was 86% in individuals who did not have additional histopathological risk factors and 55% in those patients who did (p = 0.46). The precise role of postoperative radiotherapy in people with HNC and documented metastasis in a single cervical lymph node remains to be defined including the identification of select individuals who may truly benefit from the combined therapy program.
Polytool: Polynomial interpretations as a basis for termination analysis of logic programs
Authors: NGUYEN MANH THANG , DE SCHREYE DANNY , GIESL JÜRGEN , SCHNEIDER-KAMP PETER 
Published: February 2010

AbstractOur goal is to study the feasibility of porting termination analysis techniques developed for one programming paradigm to another paradigm. In this paper, we show how to adapt termination analysis techniques based on polynomial interpretations—very well known in the context of term rewrite systems—to obtain new (nontransformational) termination analysis techniques for definite logic programs (LPs). This leads to an approach that can be seen as a direct generalization of the traditional techniques in termination analysis of LPs, where linear norms and level mappings are used. Our extension generalizes these to arbitrary polynomials. We extend a number of standard concepts and results on termination analysis to the context of polynomial interpretations. We also propose a constraint-based approach for automatically generating polynomial interpretations that satisfy the termination conditions. Based on this approach, we implemented a new tool, called Polytool, for automatic termination analysis of LPs.
Oil in the age of steam
Authors: Madureira Nuno Luís 
Published: February 2010

AbstractThis article explains how oil as an energy carrier evolved alongside the technology of the steam engine. In practical terms, fuel oil was adapted to machines that were originally devised to be coal-fuelled and this led to the flexible switchover between energy carriers. The article links the micro account of technological developments with the macro records of energy consumption, to reveal how steam technology set the stage for the commoditization of oil, the customary fuel of the internal combustion engine. The analysis of the oil–steam combine embraces its diffusion across leading producing nations such as Russia and the United States, the diffusion in industrial and transport activities in South America, and the diffusion throughout European navies. What was at stake was the transformation of oil into a geostrategic good and the triggering of an international race for the seizure of fossil fuels.
Bacteriochlorophyll and community structure of aerobic anoxygenic phototrophic bacteria in a particle-rich estuary
Authors: Cottrell Matthew T , Ras Josephine , Kirchman David L 
Published: February 2010

Abstract
Photoheterotrophic microbes use organic substrates and light energy to satisfy their demand for carbon and energy and seem to be well adapted to eutrophic estuarine and oligotrophic oceanic environments. One type of photoheterotroph, aerobic anoxygenic phototrophic (AAP) bacteria, is especially abundant in particle-rich, turbid estuaries. To explore questions regarding the controls of these photoheterotrophic bacteria, we examined their abundance by epifluorescence microscopy, concentrations of the light-harvesting pigment, bacteriochlorophyll a (BChl a) and the diversity of pufM and 16S ribosomal RNA (rRNA) genes in the Chesapeake Bay. Concentrations of BChl a varied substantially, much more so than AAP bacterial abundance, along the estuarine salinity gradient. The BChl a concentration was correlated with turbidity only when oceanic and estuarine waters were considered together. Concentrations of BChl a and BChl a quotas were higher in particle-associated than in free-living AAP bacterial communities and appear to reflect physiological adaptation, not different AAP bacterial communities; pufM genes did not differ between particle-associated and free-living communities. In contrast, particle-associated and free-living bacterial communities were significantly different, on the basis of the analysis of 16S rRNA genes. The BChl a quota of AAP bacteria was not correlated with turbidity, suggesting that pigment synthesis varies in direct response to particles, not light attenuation. The AAP bacteria seem to synthesize more BChl a when dissolved and particulate substrates are available than when only dissolved materials are accessible, which has implications for understanding the impact of substrates on the level of photoheterotrophy compared with heterotrophy in AAP bacteria.
