Published: October 2009

AbstractThis paper presents the analysis on two weather radar data sets, collected at Spino d'Adda (Italy) and Bordeaux (France), for the simulation and the performance evaluation of a site diversity system. Results from the two locations are compared and the impact of different factors such as the baseline and link orientation is assessed and related to the local climatologic characteristics. The results obtained are then compared with the model currently recommended by the ITU‐R for the estimation of the site diversity performance. A linkage is then established between the preferable baseline orientation and the predominant direction of the rain field advection. The rain field displacement is finally shown to be well approximated by the wind speed and direction relative to the 700 hPa isobar extracted from the European Center for Medium‐range Weather Forecast ERA‐40 meteorological database.

Comparative Analysis of Primary and Secondary Structure for Pea Isoamylase Isoforms Predicts Different Catalytic Properties against Glucan Substrates
Authors: Hussain Hasnain , Martin Cathie 
Published: October 2009

AbstractScreening of pea cDNA library has resulted in isolation of three different genes that encode different isoforms of isoamylase. From analysis and comparison with other isoamylase genes available from public databases and also from cDNA clones encoding isoforms of potato isoamylase, there are likely to be three isoforms of isoamylase in most (all) angiosperm genomes although so far only few plant species have their cDNA or genomic DNA characterised for these genes. Analysis of the primary structure of the isoforms of isoamylase from pea showed that all of them possess characteristics to bind glucan substrates. However, one of the isoform, Psisa2, most likely does not have catalytic activity. Since the analysis of this isoform concluded that it retained the characteristics to bind to glucans, Psisa2 might play a non‐catalytic role during the formation or degradation of starch.

Published: October 2009

AbstractObjectiveTo investigate if anti‐Ro/SSA antibody‐exposed fetuses with prolonged atrioventricular (AV) time intervals also have prolongation of the isovolumetric contraction time (ICT).MethodsSeventy‐eight anti‐Ro/SSA (including 70 anti‐Ro52) antibody‐exposed fetuses at risk for congenital heart block (CHB) were followed weekly, between 18 and 24 weeks of gestation, with two Doppler echocardiographic methods designed to detect signs of first‐degree AV block. One of these AV time measurements, using hemodynamic events from the mitral valve and aortic outflow as indirect markers of atrial and ventricular depolarization (MV‐Ao), was also used to calculate a time interval representing an early phase of systolic cardiac performance, i.e. the ICT. Two hundred and eighty‐four women with normal pregnancies served as controls for AV time intervals and another 106 were used to establish an ICT reference range.ResultsStrong positive relationships were found between ICT and MV‐Ao time intervals (r = 0.91, P < 0.001), as well as between ICT and time intervals obtained from the superior vena cava and aorta (r = 0.85, P < 0.001). The ICT was estimated to contribute more than 50% of the total AV time prolongation. Abnormal AV time and ICT intervals were only seen in anti‐Ro52 positive pregnancies.ConclusionsThe ICT is an important contributor to prolongation of AV time intervals. This observation suggests that anti‐Ro52/SSA antibody‐exposed fetal hearts have not only disturbed electrical conduction but also decreased mechanical performance. Moreover, our findings have implications for the interpretation of AV time intervals used for surveillance of fetuses at risk for developing CHB. Copyright © 2009 ISUOG.

Beger's operation and the Berne modification: origin and current results
Authors: Mihaljevic André L. , Kleeff Jörg , Friess Helmut 
Published: October 2009

AbstractBackground/purposeThe purpose of this paper is to illuminate the origin and current results of the duodenum‐preserving pancreatic head resection (DPPHR) developed by Beger in the 1970s, as well as its simplified Berne modification, for patients suffering from chronic pancreatitis (CP). Indications for the procedures and their results are presented on the basis of available data.MethodsA selected review was made of the available data on the DPPHR developed by Beger and its modifications.ResultsThe organ‐sparing DPPHR developed by Beger, and its modifications, provide better pain relief, better preservation of exocrine and endocrine pancreatic function, and a superior quality of life compared with the more radical pancreaticoduodenectomy (PD, with or without pylorus‐preservation), once the standard treatment for patients with CP. Recently published data on the long‐term follow‐up of studies comparing PD to DPPHR indicate that the initial benefits of DPPHR over PD might be less pronounced in the long‐run.ConclusionsThe organ‐preserving DPPHR developed by Beger, and its modifications, have become established and well‐evaluated surgical treatment options for patients with CP.
A remark on gauge transformations and the moving frame method
Authors: Schikorra Armin 
Published: October 2009

In this note we give a shorter proof of recent regularity results on elliptic partial differential equations with antisymmetric structure presented in Rivière (2007) [23], Rivière and Struwe (2008) [24]. We differ from the mentioned articles in using the direct method of Hélein's moving frame, i.e. minimizing a certain variational energy-functional, in order to construct a suitable gauge transformation. Though this is neither new nor surprising, it enables us to describe a proof of regularity using elementary arguments of calculus of variations and algebraic identities.
Moreover, we remark that in order to prove Hildebrandt's conjecture on regularity of critical points of 2D-conformally invariant variational problems one can avoid the application of the Nash–Moser imbedding theorem.

Résumé
La note contient une démonstation plus courte des résultats récents sur la régularité des solutions d'équations aux dérivées partielles ayant une structure antisymétrique comme dans Rivière (2007) [23], Rivière and Struwe (2008) [24]. La différence par rapport méthodes dans ces articles est qu'on utilise directement les « répères mobiles » developpés par Hélein, c'est – à – dire la minimisation d'une énergie variationnelle, dans la but de construire une transformation de Jauge. Même si ce n'est ni nouveau ni étonnant, ceci nous permet de mener une démonstration de régularité par des arguments élémentaires du calcul variationnel et des identités algébriques.
De plus, nous remarquons que la conjecture d'Hildebrandt, concernant la regularité des points critiques des problèmes variationnels invariants sous des transformations conformes, ne nécessite pas l'application du théorème dimmersion de Nash et Moser.
Evaluation of peripheral nerve injury⋆
Authors: Campbell William W. 
Published: October 2009

AbstractCommon etiologies of peripheral nerve injury include penetrating injury, crush, stretch, and ischemia. Management of nerve injury requires familiarity with the relevant anatomy, pathology, pathophysiology, and the surgical principles, approaches and concerns. Surgical repair is done at varying time intervals after the injury, and there are a number of considerations in deciding whether and when to operate. In neurapraxia, the compound muscle action and nerve action potentials on stimulating distal to the lesion are maintained indefinitely; stimulation above the lesion reveals partial or complete conduction block. The picture in axonotmesis and neurotmesis depends on the time since injury. The optimal timing for an electrodiagnostic study depends upon the clinical question being asked. Proximal nerve injuries are problematic because the long distance makes it difficult to reinnervate distal muscles before irreversible changes occur. In the early management of peripheral nerve injury, control of pain is often the most pressing consideration and a number of approaches may be used to bring relief.

Published: October 2009

AbstractPrevious data suggest that nucleotides are important mitogens in the developing chick retina. Here, we extended the study on the mitogenic effect of ATP to newborn mouse retinal explants. Our results showed that P2Y1 receptors were widely distributed in C57bl/6 mice retina and that the majority of PCNA positive cells co‐localized with P2Y1 receptor. To evaluate proliferation, retinal explants obtained from newborn mice were incubated with 0.5 μCi [3H]‐thymidine or 3 μM BrDU 1 h before the end of culture. Our data showed that ATP induced a dose‐dependent increase in [3H]‐thymidine incorporation, an effect that was mimicked by ADP but not by UTP and was blocked by the P2 antagonist PPADS in a dose‐dependent manner. The increase in [3H]‐thymidine incorporation induced by ATP was only observed in explants cultured for 3 days or less and was mimicked by the ectoapyrase inhibitor ARL 67156. It corresponded to an increase in the number of BrdU+ cells in the neuroblastic layer (NL) of the tissue, suggesting that ATP, through activation of P2Y1 receptors, induced proliferation of late developing progenitors in retinal explants of newborn mice. The increase in the number of BrdU+ cells was observed across the whole NL when explants were incubated with ATP for 24 h and no increase in the number of p‐histone H3 labeled cells could be noticed at this time point. In longer incubations of 48 h with ATP or 24 h with ATP followed by a period of 24 h in fresh medium, an increase in the number of BrdU+ cells promoted by ATP was observed only in the middle and outer, but not in the inner NL. In these conditions, an increase in the number of p‐histone H3 labeled cells was detected in the outer NL, suggesting that ATP induced cells to enter S and progress to G2 phase of the cell cycle in the first 24 h period of incubation. ATP also induced an increase and a decrease in the expression of cyclin D1and p27kip1, respectively, in retinal progenitors of the NL. While the increase in the expression of cyclin D1 was observed when retinal explants were incubated for 3 h or longer periods of time, the decrease in the expression of p27kip1 was noticed only after 6 h incubation with ATP. Both effects were blocked by the P2 receptor antagonist PPADS. These data suggest that ATP induces cell proliferation in retinal explants by inducing late developing progenitors to progress from G1 to S phase of cell cycle.
The impact of information technology use on plant structure, practices, and performance: An exploratory study
Authors: Heim Gregory R. , Peng David Xiaosong 
Published: October 2009

AbstractFirms have been investing millions of dollars on information technology (IT) in their manufacturing plants. However, the research literature is unclear about the extent and scope of the impact of IT use on plant operations. This study examines the impact of IT use on the structure, practices, and performance of manufacturing plants. Drawing on information systems and operations management literature, the study differentiates between plant IT use (i) at the process level, (ii) due to internal process integration, and (iii) due to customer and supplier collaboration, labeled as process intelligence, integration intelligence, and collaboration intelligence, respectively. The study also accounts for intelligence gathering due to statistical process control (SPC) practices. The proposed impacts of IT use are examined using data from a study sample of manufacturing plants from electronics, machinery and transportation component industries. Overall, the evidence suggests that SPC has a broader and more significant impact on many aspects of plant operations than the individual dimensions of IT use. However, the three dimensions of IT use do exhibit distinct effects on plant structure, practices, and performance. Process intelligence tends to be associated with plant size and productivity, while integration intelligence and collaboration intelligence tend to be associated with work practices related to increased organizational decentralization and a flexible technology focus.
ON THE ORDER OF ARC-STABILIZERS IN ARC-TRANSITIVE GRAPHS
Authors: VERRET GABRIEL 
Published: October 2009

AbstractLet p be a prime. We say that a transitive action of a group L on a set Ω is p-sub-regular if there exist x,y∈Ω such that 〈Lx,Ly〉=L and LYx≅ℤp, where Y =yLx is the orbit of y under Lx. Our main result is that if Γ is a G-arc-transitive graph and the permutation group induced by the action of Gv on Γ(v) is p-sub-regular, then the order of a G-arc-stabilizer is equal to ps−1 where s≤7, s≠6, and moreover, if p=2, then s≤5. This generalizes a classical result of Tutte on cubic arc-transitive graphs as well as some more recent results. We also give a characterization of p-sub-regular actions in terms of arc-regular actions on digraphs and discuss some interesting examples of small degree.

Published: October 2009

AbstractIn this paper we discuss the simplicity criteria of (−1,−1)-Freudenthal Kantor triple systems and give examples of such triple systems, from which we can construct some Lie superalgebras. We also show that we can associate a Jordan triple system to any (ε,δ)-Freudenthal Kantor triple system. Further, we introduce the notion ofδ-structurable algebras and connect them to (−1,δ)-Freudenthal Kantor triple systems and the corresponding Lie (super)algebra construction.
EFFECT OF SOWING DENSITY AND SEEDBED TYPE ON YIELD AND YIELD COMPONENTS IN BAMBARA GROUNDNUT (VIGNA SUBTERRANEA) IN WOODLAND SAVANNAS OF COTE D'IVOIRE
Authors: KOUASSI N'. J. , ZORO BI I. A. 
Published: October 2009

SUMMARYBambara groundnut (Vigna subterranea) is one of the most promising food legumes in Africa, due to its agronomic and nutritional potential. To take advantage of these attributes, several research programmes gathering agronomic and genetic data are being implemented throughout Africa. In this context, the response of yield and yield components to sowing density and seedbed type were tested in a three-year (2005, 2006 and 2007) field experiment using a bambara groundnut landrace with a semi-bunch growth habit. Three plant population densities: 13 900 plants ha−1, 62 500 plants ha−1 and 250 000 plants ha−1 were coupled with two seedbed types – raised and flat. A factorial trial using a split-plot design with three replicates was set up to analyse seed yield and plant biomass, as well as nine yield components. Sowing density influenced significantly (p < 0.05) seed yield (direct relationship) and most of the yield components (inverse relationship). The highest seed yields were observed on high-density plots (4.11 ± 1.05 ha−1). In contrast, seedbed type and year of experiment did not influence significantly the marketable yield and plant biomass (p > 0.05). This result has been attributed to the suitability of the amount and distribution of rainfall and temperature for the production of bambara groundnut at the target site. Based on the trend of yield response, cultivation of landraces of bambara groundnut characterized by a semi-bunch growth habit at high density on flat seedbeds was suggested in woodland savannas of Côte d'Ivoire to enhance seeds yield and reduce labour.
Pressure dressing after excision of preauricular sinus: suture transfixion of silicone sheets
Authors: Heo K W , Baek M J , Park S K 
Published: October 2009

AbstractObjective:After excision of a preauricular sinus, a head bandage compressive dressing is usually used to reduce dead space and to decrease the risk of recurrence. However, such use of a head bandage may cause various problems. We assessed a new method of compressive dressing, using suture transfixion of silicone sheets to the former sinus tract, following preauricular sinus excision.Methods:This retrospective study reviewed the medical records of patients undergoing preauricular sinus excision in a tertiary referral centre over a five-year period. After excision of the preauricular sinus, patients underwent suture transfixion of silicone sheets. Post-operative outcomes were analysed.Results:The new dressing method was performed on 50 ears of 37 patients. The post-operative incidence of recurrence and haematoma formation was 4 and 2 per cent, respectively. Other problems possibly caused by head bandaging, such as headache, facial flushing, and nausea and/or vomiting, were not observed.Conclusion:Compressive dressing by suture transfixion of silicone sheets is safe and effective following preauricular sinus excision.
Airway compromise secondary to vagus nerve stimulator: case report and implications for otolaryngologists
Authors: Bhatt Y M , Hans P S , Belloso A 
Published: October 2009

AbstractIntroduction:Vagus nerve stimulators are devices used in the management of patients with drug-refractory epilepsy unsuitable for resective or disconnective surgery. Implanted usually by neurosurgeons, these devices are infrequently encountered by otolaryngologists. Despite significant anti-seizure efficacy, side effects related to laryngopharyngeal stimulation are not uncommon.Case report:A 28-year-old man with a history of effective vagus nerve stimulator use presented with a cluster of seizures and respiratory distress associated with intermittent stridor. The duration of stridor corresponded to the period of vagus nerve stimulation. Endoscopy revealed forced adduction of the left vocal fold against a medialised right vocal fold. The device was switched off and the stridor immediately resolved.Conclusion:Airway compromise is an under-recognised side effect of vagus nerve stimulation. We describe the first known case of stridor and contralateral vocal fold palsy in a vagus nerve stimulator user. We highlight the need for better understanding amongst otolaryngologists of the laryngopharyngeal side effects of this technology.

Published: October 2009

BackgroundIn an effort to group mental disorders on the basis of etiology, five clusters have been proposed. Here we consider the validity of the cluster comprising selected psychotic and related disorders.MethodA group of diagnostic entities classified under schizophrenia and other psychotic disorders in DSM-IV-TR were assigned to this cluster and the bordering disorders, bipolar (BD) and schizotypal personality disorders (SPD), were included. We then reviewed the literature in relation to 11 validating criteria proposed by the DSM-V Task Force Study Group.ResultsRelevant comparisons on the 11 spectrum criteria are rare for the included disorders except for schizophrenia and the two border conditions, BD and SPD. The core psychosis group is congruent at the level of shared psychotic psychopathology and response to antipsychotic medication. BD and SPD are exceptions in that psychosis is not typical in BD-II disorder and frank psychosis is excluded in SPD. There is modest similarity between schizophrenia and BD relating to risk factors, neural substrates, cognition and endophenotypes, but key differences are noted. There is greater support for a spectrum relationship of SPD and schizophrenia. Antecedent temperament, an important validator for other groupings, has received little empirical study in the various psychotic disorders.ConclusionsThe DSM-IV-TR grouping of psychotic disorders is supported by tradition and shared psychopathology, but few data exist across these diagnoses relating to the 11 spectrum criteria. The case for including BD is modest, and the relationship of BD to other mood disorders is addressed elsewhere. Evidence is stronger for inclusion of SPD, but the relationship with other personality disorders along the 11 criteria is not addressed and the absence of psychosis presents a conceptual problem. There are no data along the 11 spectrum criteria that are decisive for a cluster based on etiology, and inclusion of BD and SPD is questionable.
Where should bipolar disorder appear in the meta-structure?
Authors: Goldberg D. P. , Andrews G. , Hobbs M. J. 
Published: October 2009

BackgroundThe extant major psychiatric classifications, DSM-IV and ICD-10, are purportedly atheoretical and largely descriptive. Although this achieves good reliability, the validity of a medical diagnosis is greatly enhanced by an understanding of both risk factors and clinical history. In an effort to group mental disorders on the basis of risk factors and clinical manifestations, five clusters have been proposed. The purpose of this paper is to consider the position of bipolar disorder (BPD), which could be either with the psychoses, or with emotional disorders, or in a separate cluster.MethodWe reviewed the literature on BPD, unipolar depression (UPD) and schizophrenia in relation to 11 validating criteria proposed by the DSM-V Task Force Study Group, and then summarized similarities and differences between BPD and schizophrenia on the one hand, and UPD on the other.ResultsThere are differences, often substantial and never trivial, for 10 of the 11 validators between BPD and UPD. There are also important differences between BPD and schizophrenia.ConclusionBPD has previously been classified together with UPD, but this is the least justifiable place for it. If it is to be recruited to a ‘psychotic cluster’, there are several important respects in which it differs from schizophrenia, so the cluster would have a division within it. The alternative would be to allow it to be in an intermediate position in a cluster of its own.
Scotus' voluntarist approach to the atonement reconsidered
Authors: Yang Andrew S. 
Published: October 2009

AbstractMany studies criticise John Duns Scotus (c. 1265–1308) for reducing the atoning sacrifice of Christ to a merit of finite worth and making its atoning power completely dependent on the accepting will of God, such that if it pleased God, even a purely creaturely sacrifice of an angel or a saint would have sufficed to redeem the elect. This article discredits this sort of criticism by demonstrating that Scotus situates his argument for a finite worth of Christ's merit within the framework of his larger argument for the infinite sufficiency of Christ's merit. A cogent examination of the ways in which Scotus posits a merit of finite intrinsic worth and arrives at its infinitely sufficient atoning power reveals that only the merit of a God-man can achieve this sort of sufficiency and that the nature of Scotus' voluntarism that underlies his concept of divine acceptation is nowhere as radical as it is usually portrayed.
Putting the ‘extra’ back into Calvinism
Authors: Habets Myk 
Published: October 2009

AbstractWith a long and venerable history in both Catholic and Protestant traditions the doctrine represented by the termextra Calvinisticumhas fallen out of favour within contemporary theologies of the cross. Through an examination of the history of the doctrine and its constituent features the present article advocates the reclamation of the doctrine as a necessary component for a contemporary theology of the atonement, with special emphasis on the trinitarian dimensions of the death of God on the cross. Theextra Calvinisticumis then adopted to refute contemporary theologies of a suffering God.
