Le pont de Barbegal au vallon des Arcs à Fontvieille (Bouches-du-Rhône) : Etude archéologique de la dérivation de l'aqueduc d'Arles
Authors: Leveau Philippe , Thernot Robert 
Published: March 2010

In connection with the construction of the Barbegal mills, a suspended aqueduct was built for the water-supply of the factory by the means of the southern branch of the aqueduct of Arles. It is composed of two parts : one with solid masonry walls in opus caementicium with an opus vittatum facing, the other with 28 arches built with the same techniques in the continuity of the masonry wall. The impost and the basis of the piers which support the arches are made of large mollasse blocks. On one of the arches being preserved, a mark from a rebuilding presumably following a voluntary destruction. An estimation of the flow is given here.

Le Terrier de Biard à Segonzac (Charente)
par Claude Burnez, Jean-Pierre Pautreau, Michel Gruet, Pierre-Roland Giot et Charles-Tanguy Le Roux

Le gisement du Terrier de Biard à Segonzac (Charente) fut découvert en 1952 et des photographies aériennes permirent alors de dresser un plan approximatif des traces pouvant indiquer des fossés. En 1959, 1961 et 1962, trois campagnes de fouilles furent effectuées par une équipe anglo-française.
En C, entre les parcelles du vignoble, deux fossés furent explorés sur 1 m de large. Ils ont livré un matériel homogène du cycle peu-richardien, faciès continental, comprenant de la céramique à décor en relief et «peint» et des perçoirs du Moulin-de-Vent. Une datation 14C (Gsy-71) 4435 ± 200 ans BP a été obtenue.
En B, la fouille ne donna aucun résultat.
En A, furent rencontrés successivement : un niveau d'habitat peu-richardien contemporain des fossés de C ; un petit fossé du Néolithique final creusé par les Artenaciens ; quatre trous de poteaux qu'il n'est pas possible de rattacher à l'une ou l'autre des structures précédentes ; une fosse allongée comblée de pierrailles et un petit foyer qui doivent appartenir au Bronze final.
Le bilan est double : premièrement le riche matériel recueilli permet de préciser notre connaissance du Peu- Richardien continental ; deuxièmement la stratigraphie observée montre son antériorité, du moins à Biard, par rapport à la civilisation d'Artenac dans une période chronologique où les datations 14C réciproques se chevauchent.
Étude archéologique
Authors: Mantel Etienne 
Published: March 2010

During the 1985-1986 winter, five fairly scattered individual inhumations burials, three of which are definitely chalcolithic, were excavated in the Boucle du Vaudreuil, a meander of the lower Seine.
Two of them (3 and 4) could not be dated. Grave goods of the beaker type accompanied burials 1 and 2, in which the skeletons were lying in a flexed position.
Burial 5, which had no associated artifacts, consisted of an adult and two perinatal children. Radiocarbon dating, carried out on the bones from burials 2 and 5, enables us to situate them chronologically (GIF 7456 : 3760 ± 90 BP ; GIF 7457 : 3880 ± 70 BP).
I. Réflexion sur les sépultures chasséennes
Authors: Mahieu Eric 
Published: March 2010

The study of a chassean necropolis at Najac (Hérault) completes the data on chassean mortuary practices. As at Dela-Laïga, and on other comparable sites, it is possible to find several individuals in a same grave.
The revision of chassean mortuary practices in France shows their diversity.
Recent studies show the relations between Catalonia and western Languedoc. The discovery at Najac of two "swords", really comparable with the dagger of Labeil (Lauroux) permits to enlarge the classic chassean contact zone between western Languedoc and the Grands Causses.
L'abri sous roche de Pont d'Ambon à Bourdeilles (Dordogne) : présentation
Authors: Célérier Guy 
Published: March 2010

L'abri sous roche de Pont d' Ambon s'ouvre sur la plaine alluviale de la Dronne, dans une région riche en abrupts et gisements paléolithiques. Deux secteurs s'individualisent dans la partie fouillée : le fond, perturbé par l'habitat magdalénien et azilien et l'avant, soumis aux processus naturels.
L'étude géologique de la séquence archéologique montre, à la base, une alternance de processus d'alluvionnements et de fragmentation, dans la partie moyenne, des colluvionnements et ruissellements, et dans la partie supérieure, une recrudescence de la fragmentation.
Les études sur le milieu biologique, déjà présentées dans le cadre de travaux académiques, sont reprises ici de manière synthétique : paléontologie des grandes faunes, des lagomorphes et des rongeurs, ichtyologie, malacologie et palynologie.
La position charnière des dépôts, à la limite de la dernière glaciation et du Postglaciaire, aurait dû faire de cette séquence une référence chronoclimatique. Or, pour le moment, la confrontation des résultats des diverses études met en évidence de nombreuses divergences. Il en résulte des interrogations sur la signification des données prises en compte dans un gisement préhistorique.
Présentation

Published: March 2010

Les grottes de Saint-Thibaud-de-Couz s'ouvrent à 500 m d'altitude sur le flanc occidental du massif de la Chartreuse, au-dessus de la vallée de l'Hyère qui représente une importante voie de circulation entre la vallée de l'Isère et la combe de Savoie. Elles ont livré une séquence stratigraphique et culturelle particulièrement développée s'échelonnant de la fin du Dryas I à l'Actuel. Onze niveaux d'occupation se rapportant au Magdalénien supérieur, à différents groupes épipaleolithiques et au Mésolithique ancien ont été mis au jour. L'analyse de l'industrie lithique a été faite selon quatre approches :
• une recherche sur les matières premières siliceuses mettant en évidence des circulations à faible et moyenne distance et des stratégies d'approvisionnement différenciées entre le Magdalénien et l'Épipaléolithique ;
• des analyses typologique et technologique permettant de proposer un cadre chronoculturel des assemblages lithiques ; une bonne individualisation des niveaux épipaleolithiques a permis une différenciation de quatre groupes culturels évoluant de l'Alleröd au Préboréal ,
• une analyse technologique comparée de deux remontages de nucleus magdaléniens issus de blocs siliceux qui se différencient par leur texture ;
• une analyse tracéologique faisant apparaître une faible utilisation des silex, le site étant principalement voué à l'exploitation des matières tendres animales et secondairement à des activités de manufacture avec utilisation de l'ocre.
L'analyse des parures en coquillages marins du Magdalénien supérieur suggère des groupes bien implantés dans la zone périalpine en contacts suivis avec les groupes suisses et en relation épisodique avec ceux du Bassin parisien. L'ensemble des résultats milite en faveur de séjours épisodiques et de courte durée.
II. Les parures du Néolithique final à Chalain et Clairvaux

Published: March 2010

Correlation between nine littoral dwelling sites of the lakes of Chalain and Clairvaux (Jura, France) has allowed to build an almost continuous chronology for the final Neolithic, covering the period from 3200 to 2600 BC. This sequence is checked through dendrochronology : it spans the succession of the Horgen, Clairvaux and Chalain cultures. For this sequence, the study of 484 objects of adornment out of wood, stone, bone, antler and shell was done, in connection with the ceramic evolution and the cultural stimuli formerly recognized.
This exceptional series of well dated ornaments allows to show the coming of outside populations in the Combe d'Ain, and in particular small groups coming from the Horgen of Western Switzerland and from the Ferrières of Ardèche, echoing what had been already perceived in the ceramic styles. This series allows also to distinguish phases of stylistical regionalization, as in the case of local manufactures of ornaments, and the reinterpretation of the Ferrières symbols. Further evidences are attained : the evolution of the symbolic of ornaments closely follows rapid changes of the environmental context and of the economy. To an ancient phase (Horgen 3200 BC) where hunting, trophy quest and the use of only slightly modified animal ornaments were prevalent, succeeds a recent one (Clairvaux, 2800 BC) where beads and pendants, made out of stone, were privileged whereas deforested landscape and husbandry take on importance.
This striking parallelism between the symbolic data and the environmental context could be explained by social determinisms of general value, those linked to variations in the density of the population and to the impact of man on the forest.
La grotte ornée Mayenne-Sciences (Thorigné-en-Charnie, Mayenne) : un exemple d'art pariétal d'époque gravettienne en France septentrionale
Authors: Pigeaud Romain , Bouchard Michel , Laval Eric 
Published: March 2010

La cueva ornada de Mayenne-Sciences (Thorigné-en-Charnie, Mayenne) posee cuatro caracteristicas principales : 1) está aislada geográficamente, siendo apartada de las grandes "provincias" como son Aquitania o el Lot ; 2) está aislada culturalmente : en efecto, forma parte del grupo de nueve cavidades o abrigos atribuidos al Paleolitico superior del Norte de Francia (con las cuevas de Gouy y Orival en Normandia, Boutigny, Le Croc-Marin y Les Trois Pignons en Essone, la grotte du Cheval y la Grande Grotte de Arcy-sur-Cure en Borgona, y Church Hole en Inglaterra) ; sin embargo, si se exceptúa las cuevas del valle de la Cure, todas las otras manifestaciones artisticas pueden atribuirse al Magdaleniense, mientras que dos dataciones 14C efectuadas en un caballo de Mayenne-Sciences remiten a una época gravetiense de 25 000 anos más o menos ; 3) esta aislada arqueológicamente, pues el carácter antiguo de las excavaciones no permite juntar las secuencias del Paleolitico superior encontradas a proximidad con las de otros grandes sitios de referencia del Périgord o de Poitou-Charentes ; 4) es "aberrante" desde el punto de vista del estilo y de las construcciones simbolicas.
Tras un estudio exhaustive, en el que analizaremos y estableceremos con precision el contexto geologico, arqueológico y artistico de la cueva, describiremos detenidamente cada unas de sus representaciones. Intentaremos luego establecer una sintesis de los sitios de arte parietal y mobiliario en las inmediaciones de Mayenne-Sciences. Conduciendo mas alla nuestro analisis, trataremos de situarla en el contexto de una tendencia figurativa que proponemos nombrar "art de la silhouette ". Dicha tendencia fue mayoritaria en la Europa ante-magdaleniense. Mostraremos, por fin, que el caracter "aberrante" del decorado de Mayenne-Sciences contribuye a aislarla al margen de las grandes corrientes culturales prehistoricas, al igual que ocurre con otros ejemplos de cuevas ornadas. Estas cuevas se reunen bajo el término de "grotte-limite ", siendo situadas al extremo de la zona de influencia de una "provincia" particular, que en el caso de Mayenne-Sciences se situaria probablemente en la región de Quercy.

The Bell Beaker settlement site of La Noue, discovered in 1992 during rescue excavations, considerably renews knowledge
on this period in the eastern part of the Burgundy region, as well contributing to the general question of Bell Beakers in a domestic context.
The spatial distribution of archaeological remains revealed several units, including two complete houses and a probable granary. The latter structure was built on wooden uprights, while the houses seem to have been built on horizontal beams, a form of architecture adapted to local damp conditions.
The settlement produced a large quantity of pottery and a small lithic assemblage dominated by end scrapers and splintered pieces.
Decoration patterns on vessels, mainly comb-impressed, are typical of the Burgundy region (horizontal lines, hatched bands, ladder motifs, chevrons). Coarse ware is characterized by types widely found in Europe (undecorated jars or jars with a cordon below the rim), as well as by central European types (jugs and flagons, polypod bowls, vessels with horizontal lugs). While flint raw materials were collected locally, clay analyses reveal that a significant number of vessels come from the right bank of the river Saône.
Together with the sites of Noir Bois and Champ-Vully in Switzerland and Derrière le Château in the Ain region, La Noue provides a representative group of finds for the Burgundy-Jura Bell Beaker group. Comparative analysis shows that La Noue occupies
an intermediate position between Noir Bois, heavily influenced by central Europe, and Derrière le Château, related more to the
Mediterranean.

Sample Size Reassessment in Non-inferiority Trials
Authors: Friede T. , Kieser M. 
Published: March 2010

SummaryObjectives: Analysis of covariance (ANCOVA) is widely applied in practice and its use is recommended by regulatory guidelines. However, the required sample size for ANCOVA depends on parameters that are usually uncertain in the planning phase of a study. Sample size recalculation within the internal pilot study design allows to cope with this problem. From a regulatory viewpoint it is preferable that the treatment group allocation remains masked and that the type I error is controlled at the specified significance level. The characteristics of blinded sample size reassessment for ANCOVA in non-inferiority studies have not been investigated yet. We propose an appropriate method and evaluate its performance.Methods: In a simulation study, the characteristics of the proposed method with respect to type I error rate, power and sample size are investigated. It is illustrated by a clinical trial example how strict control of the significance level can be achieved.Results: A slight excess of the type I error rate beyond the nominal significance level was observed. The extent of exceedance increases with increasing non-inferiority margin and increasing correlation between outcome and covariate. The procedure assures the desired power over a wide range of scenarios even if nuisance parameters affecting the sample size are initially mis-specified.Conclusions: The proposed blinded sample size recalculation procedure protects from insufficient sample sizes due to incorrect assumptions about nuisance parameters in the planning phase. The original procedure may lead to an elevated type I error rate, but methods are available to control the nominal significance level.
Heterochromia Iridis and Pertinent Clinical Findings in Patients with Glaucoma Associated with Sturge–Weber Syndrome
Authors: Aggarwal Nalini K. , Gandham Sai B. , Weinstein Rebecca , Saltzmann Robert , Walton David S. 
Published: March 2010

Purpose:
To examine the clinical and gonioscopic findings in patients with glaucoma associated with Sturge–Weber syndrome.

Methods:
Retrospective review of clinical findings of all patients with Sturge–Weber syndrome who presented between January 1978 and December 2003. Koeppe gonioscopy was performed under general anesthesia and findings were photographed when feasible. Iris color was documented by color sketch or photograph at initial presentation. Fisher exact test was used to determine whether the presence of heterochromia was statistically higher in the glaucomatous group.

Results:

Fifty-five patients who met inclusion criteria were identified, of whom 44 (80%) had glaucoma. Unilateral glaucoma was diagnosed in 30 eyes and bilateral glaucoma in 14 eyes, yielding 58 eyes with glaucoma and 52 eyes without. Gonioscopic examination revealed distinct anatomic abnormalities in the anterior chamber angle in 32 (55%) of the glaucomatous eyes in contrast to the normal fellow eyes in patients with unilateral glaucoma and to the patients without glaucoma. Heterochromia iridis with darker iris on the glaucomatous side was present in 11 of the 30 patients with unilateral glaucoma (37%,
P
< .001) but in none of the patients without glaucoma.

Conclusion:
The characteristics observed in the anterior chamber angle in this large, uniquely examined series are the first reported to the authors’ knowledge and may support a role for neural crest derived anomalies in the pathogenesis of glaucoma in these infant eyes. Careful examination for heterochromia iridis may be judicious in these patients.
Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women
Authors: Varley Thornton Abigail J. , Graham‐Kevan Nicola , Archer John 
Published: March 2010

AbstractThe aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

Enhancement of Light Extraction Through the Wave‐Guiding Effect of ZnO Sub‐microrods in InGaN Blue Light‐Emitting Diodes
Authors: Kim Ki Seok , Kim Sang‐Mook , Jeong Hyun , Jeong Mun Seok , Jung Gun Young 
Published: March 2010

AbstractThe improvement of the light extraction efficiency (LEE) of a conventional InGaN blue light‐emitting diode (LED) by the incorporation of one‐dimensional ZnO sub‐microrods is reported. The LEE is improved by 31% through the wave‐guiding effect of ZnO sub‐microrods compared to LEDs without the sub‐microrods. Different types of ZnO microrods/sub‐microrods are produced using a simple non‐catalytic wet chemical growth method at a low temperature (90 °C) on an indium‐tin‐oxide (ITO) top contact layer with no seed layer. The crystal morphologies of needle‐like or flat‐top hexagonal structures, and the ZnO microrods/sub‐microrod density and size are easily modified by controlling the pH value and growth time. The wave‐guiding phenomenon within the ZnO rods is observed using confocal scanning electroluminescence microscopy and micro‐electroluminescence spectra.
Original Fuel‐Cell Membranes from Crosslinked Terpolymers via a “Sol–gel” Strategy

Published: March 2010

AbstractHybrid organic/inorganic membranes that include a functionalized (‐SO3H), interconnected silica network, a non‐porogenic organic matrix, and a ‐SO3H‐functionalized terpolymer are synthesized through a sol–gel‐based strategy. The use of a novel crosslinkable poly(vinylidene fluoride‐ter‐perfluoro(4‐methyl‐3,6‐dioxaoct‐7‐ene sulfonyl fluoride)‐ter‐vinyltriethoxysilane) (poly(VDF‐ter‐PFSVE‐ter‐VTEOS)) terpolymer allows a multiple tuning of the different interfaces to produce original hybrid membranes with improved properties. The synthesized terpolymer and the composite membranes are characterized, and the proton conductivity of a hybrid membrane in the absence of the terpolymer is promising, since 8 mS cm−1 is reached at room temperature, immersed in water, with an experimental ion‐exchange‐capacity (IECexp) value of 0.4 meq g−1. Furthermore, when the composite membranes contain the interfaced terpolymer, they exhibit both a higher proton conductivity (43 mS cm−1 at 65 °C under 100% relative humidity) and better stability than the standard hybrid membrane, arising from the occurrence of a better interface between the inorganic silica and the poly[(vinylidene fluoride)‐co‐hexafluoropropylene] (poly(VDF‐co‐HFP)) copolymer network. Accordingly, the hybrid SiO2‐SO3H/terpolymer/poly(VDF‐co‐HFP) copolymer membrane has potential use as an electrolyte in a polymer‐electrolyte‐membrane fuel cell operating at intermediate temperatures.
Product design in price‐competitive markets: A case study of a skin moisturizing lotion

Published: March 2010

AbstractIn this article, we apply a recently developed method for product design to the formulation of skin lotions and extend its application to consider price‐competitive markets. The method is based on the use of consumer preference functions that are in turn parameters of price‐demand relations. These relationships are then embedded in a business model that aims at determining the optimal lotion formulation from the profitability point of view. The model allows to distinguish the formulation that leads to the consumer most preferred skin lotion from the most profitably one in a quantitative fashion. In the latter case, the selling price is also determined simultaneously with the optimal formulation. The example analyzed shows that the consumer most preferred lotion is not profitable, whereas a slightly less preferred lotion is very profitable. We then extend the new product design procedure to consider a competitive environment in which prices of all competitors, change dynamically until equilibrium is established. © 2010 American Institute of Chemical Engineers AIChE J, 2011
Rigorous synthesis and simulation of complex distillation networks
Authors: Ruiz Gerardo J. , Kim Seon B. , Moes Laura , Linninger Andreas A. 
Published: March 2010

AbstractRecent insights for better understanding the thermodynamic foundations of separation processes have renewed the interest in exploring energy‐efficient distillation networks. Complex column networks have substantial potential for energy savings over conventional configurations. This article introduces a computational algorithm for synthesizing such complex energy‐efficient networks. A robust feasibility criterion drives the selection of design specification and operating conditions. It will be shown that columns composed of sections whose liquid stage composition profiles have no gaps are realizable. To prove the rigor of design computations, numerous separation networks were synthesized and validated with the Aspen flowsheet simulator. By using our computational results as input, AspenPlus simulations converged in a few iterations. Our method builds on temperature collocation, a thermodynamically motivated search method for determining feasible operating conditions and design details for achieving the desired product targets. Our findings suggest that significant energy savings can be realized with rigorous complex networks synthesis for industrial separation problems. © 2010 American Institute of Chemical Engineers AIChE J, 2011
