Abstract
This paper shows the comparison obtained in the oil and gas production increase by cyclic gas injection produced at Provincia field and the cyclic solvent + gas injection (same field). According the composition of the production gas of Provincia Field (Table 1) used during the cyclic injection, is denominated as "rich gas", the molar fraction between C2 to C7+ is 31%.
The Provincia Field is a mature field that has since the late 80's the Gas Lift as artificial lift system and for our particular case, that resource compressed gas was taken at 1000 psig to cyclically inject gas production. Besides, the cyclic gas injection & cyclic solvent + gas injection technology was proved.
The cyclic rich gas injection of was put in practice in 9 wells of the field and the cyclic injection + gas was applied in the well Santos 94. For our specific case, the application of both technologies in the increase of productivity obtained in Santos 94 (API Gravity 20°) is going to compare. During the total cycle of injection & production of cyclic gas in Santos 94 an increase of oil production was obtained, 2134 Bls and 32,4 MMCF of gas. The oil and gas incremental production during the injection cycle of solvent + rich gas was 3232 Bls and 171 MMCF (32715 Equivalent Barrels).
Compact and Highly Efficient Heat Exchanger Based on Packed Beds of Nanoparticle-Doped Spheres

Abstract
In this work, we demonstrate at a laboratory scale the possibility of using a radio frequency (RF) heating system as a heat exchanger, with future applications for heavy oil processing. This laboratory work is the base for further improvements in heavy oil operations. The system consists of a pipe packed with nanoparticle-doped, superparamagnetic spheres as the bed material. The experimental results are compared to the data obtained with a volume average numerical method.
In the RF heating system, the spheres are excited when subjected to oscillating electric fields ensuing thermal energy dissipation; this mechanism is called the Neel relaxation, a type of electrical induction heating. We have tested this system’s performance using water and heavy crude oil flowing in non-electrically conductive ceramic pipes packed with different sizes and spheres materials. Pressure, temperature and electric consumption data corresponding to varying flow rates have been collected and the numerically solved heat transfer equations are used to extend the system characterization; this will allow for industrial apparatus design considerations.
Steady state data indicate that fluid heating is achieved at smaller residence times than in conventional heaters; temperature can be controlled with a great accuracy by varying the parameters of the RF generator. When heat leakage could be contained (through insulating the pipe outer wall and relatively low temperature gradients), heating efficiencies were significantly higher than 80 %. The volume average numerical method shows that the liquid flowing through the packed bed gets uniformly heated. Thermal and flow characterization are achieved for Reynolds and Nusselt numbers in the range of 10−2−102 respectively.
This set up is able to heat in an efficient and temperature accurate manner for a wide range of flow conditions, and can be potentially used as a highly efficient heat exchanger for production operations (e.g., steam generation) in areas where the construction of surface facilities (fuel storage tanks, boilers) is not possible, either for environmental reasons or for lack of land space. A RF heat exchanger would only require a reliable source of electricity.

Published: October 2016

Background and objectives
A kidney biopsy is preferred for the diagnosis of ANCA-associated vasculitis with renal involvement. The aim of our study was to evaluate the prognostic value of a histopathologic classification scheme recently proposed by an international consortium of renal pathologists in a large Norwegian cohort.

Design, setting, participants, & measurements
Patients diagnosed with ANCA-associated GN were included from the Norwegian Kidney Biopsy Registry 1991–2012. Renal morphology was classified as focal, mixed, crescentic, or sclerotic. Study end point was ESRD. Patients were followed from kidney biopsy to end of 2012.

Results
Two hundred fifty patients with ≥10 glomeruli in the biopsy were included in our study. During a median follow-up of 3.5 years (0.7–7.6), 60 cases of ESRD occurred. Ninety-six (38%) biopsies were classified as focal, 61 (24%) biopsies were classified as mixed, 71 (28%) biopsies were classified as crescentic, and 22 (9%) biopsies were classified as sclerotic; 1- and 5-year cumulative renal survival rates were 96% and 90%, respectively, for the focal class, 86% and 75%, respectively, for the mixed class, 81% and 69%, respectively, for the crescentic class, and 56% and 51%, respectively, for the sclerotic class. By multivariate Cox regression analyses, the sclerotic class had a significantly worse renal prognosis than the focal (hazard ratio, 9.65; 95% confidence interval, 2.38 to 39.16) or combined mixed/crescentic classes (hazard ratio, 3.27; 95% confidence interval, 1.41 to 7.61), but no significant differences in outcome were observed in the crescentic class compared with the mixed class (hazard ratio, 1.13; 95% confidence interval, 0.44 to 2.87) or the combined mixed/crescentic class compared with the focal class (hazard ratio, 1.93; 95% confidence interval, 0.61 to 6.12). Accuracy by receiver operator characteristic curve analysis was estimated to be 0.72 (95% confidence interval, 0.65 to 0.80). In 108 additional patients with three to nine glomeruli in the biopsy, the prognostic value of this classification scheme was unchanged.

Conclusions
The histopathologic classification is a predictor of renal outcome of moderate quality. Merging the mixed and crescentic classes in the future could simplify the scheme.
Moderating “Cry Wolf” Events with Excess MAD in Benford's Law Research and Practice
Authors: Barney Bradley J. , Schulzke Kurt S. 
Published: October 2016

ABSTRACT
False positives or “Type I errors,” wherein test results indicate fraud where none actually exists, have been described as a costly “cry wolf problem” in auditing practice. Benford's Law, which is used as one tool among many in screening for financial statement manipulation, is especially prone to false positives when applied to small and moderately sized datasets. Relying in part on Monte Carlo simulations, we describe with greater precision than extant literature the mathematical correlation between N and Mean Absolute Deviation (MAD), a statistic increasingly used for assessing deviation from Benford's Law. We recommend replacing MAD with an alternative, Excess MAD, which explicitly adjusts for N in estimating deviation from Benford's Law. Applying nonparametric, generalized additive modeling to public company financial statement numbers, we demonstrate the differing outcomes expected from Excess MAD and MAD and produce evidence suggesting that, despite Sarbanes-Oxley and Dodd-Frank legislation, Benford's Law conformity of public company financial statement numbers remained relatively stable across four decades beginning in 1970.

OBJECTIVE
We prospectively examined whether family socioeconomic status (SES) in childhood is associated with metabolic syndrome (MetS), impaired fasting glucose (IFG), or type 2 diabetes in adulthood.

RESEARCH DESIGN AND METHODS
The sample comprised 2,250 participants from the longitudinal Cardiovascular Risk in Young Finns Study cohort. Participants were 3–18 years old at baseline (mean age 10.6 years), and they were followed for 31 years. SES was characterized as reported annual income of the family and classified on an 8-point scale.

RESULTS
For each 1-unit increase in family SES in childhood, the risk for adult MetS decreased (risk ratio [95% confidence interval] 0.94 [0.90–0.98]; P = 0.003) when adjusted for age, sex, childhood cardiometabolic risk factors (lipids, systolic blood pressure, insulin, and BMI), childhood physical activity, and fruit and vegetable consumption. The association remained after adjustment for participants’ own SES in adulthood (0.95 [0.91–0.99]; P = 0.005). A similar association was seen between childhood SES and the risk of having either adult IFG or type 2 diabetes (0.96 [0.92–0.99]; P = 0.01, age and sex adjusted). This association became nonsignificant after adjustment for childhood risk factors (P = 0.08). Of the individual components of MetS, lower SES in childhood predicted large waist circumference (0.96 [0.93–0.99]; P = 0.003) and a high triglycerides concentration (0.96 [0.92–1.00]; P = 0.04) after adjustment for the aforementioned risk factors.

CONCLUSIONS
Lower SES in childhood may be associated with an increased risk for MetS, IFG, and type 2 diabetes in adulthood. Special attention could be paid to children of low SES families to decrease the prevalence of MetS in adulthood.

ABSTRACTBy using data from the International Agency for Research on Cancer publication Cancer Incidence in 5 Continents and GLOBOCAN, this report provides the first consolidated global estimation of the subsite distribution of new cases of lip, oral cavity, and pharyngeal cancers by country, sex, and age for the year 2012. Major geographically based, sex‐based, and age‐based variations in the incidence of lip, oral cavity, and pharyngeal cancers by subsite were observed. Lip cancers were highly frequent in Australia (associated with solar radiation) and in central and eastern Europe (associated with tobacco smoking). Cancers of the oral cavity and hypopharynx were highly common in south‐central Asia, especially in India (associated with smokeless tobacco, bidi, and betel‐quid use). Rates of oropharyngeal cancers were elevated in northern America and Europe, notably in Hungary, Slovakia, Germany, and France and were associated with alcohol use, tobacco smoking, and human papillomavirus infection. Nasopharyngeal cancers were most common in northern Africa and eastern/southeast Asia, indicative of genetic susceptibility combined with Epstein‐Barr virus infection and early life carcinogenic exposures (nitrosamines and salted foods). The global incidence of lip, oral cavity, and pharyngeal cancers of 529,500, corresponding to 3.8% of all cancer cases, is predicted to rise by 62% to 856,000 cases by 2035 because of changes in demographics. Given the rising incidence of lip, oral cavity, and pharyngeal cancers and the variations in incidence by subsites across world regions and countries, there is a need for local, tailored approaches to prevention, screening, and treatment interventions that will optimally reduce the lip, oral cavity, and pharyngeal cancer burden in future decades.

Published: October 2016

A field study was conducted to select suitable genotype(s) for varying planting dates and to compare the average performance of the genotypes in different environments. The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh with ten (nine Triticum aestivum and one Triticum turgidum) wheat genotypes. The genotypes were planted at three different dates during November 2012 to March 2013. Analysis of variance for the genotypes showed significant variation which revealed the presence of considerable amount of genetic variability among different genotypes. Significant genotype x environment interaction was obtained for all studied characters and those were tested against pooled error. Environment + (genotype ^ environment) component and genotype ^ environment (linear) component also showed significant variation and the genotypes performed differently in different environments. Except pooled deviation of linear components of genotype-environment interaction were significant for all the characters. So the differences in stability for different characters were due to the linear response and not for non-linear function. Considering all the characters, genotypes G4, G6, G9 performed better in overall environments. The genotype G10 performed better in poor condition whereas G7 performed better in favorable environment. Among three different sowing dates, optimum sowing (sowing at 20 November, 2012) performed better for most of the genotypes and gradually decreased with late sowing.
New distribution records of the savanna specialist fungus-farming ant Cyatta Sosa-Calvo et al. (Hymenoptera: Formicidae: Myrmicinae)
Authors: Oliveira Aline , Feitosa Rodrigo , Vasconcelos Heraldo , Maravalhas Jonas 
Published: October 2016

The fungus-farming ant genus Cyatta (Formicidae: Myrmicinae) is represented by a single species, C. abscondita Sosa-Calvo et al., known from a few localities in Brazil (in the states of Ceará, Minas Gerais, São Paulo and the Distrito Federal), and a single locality in the Misiones province, Argentina. Cyatta is known to occur predominantly in savanna habitats and occasionally in the transition zones between the Atlantic Forest and Cerrado.
The new records reported here significantly expand the previously known distribution of Cyatta abscondita and provide further support for the intimate relation between this species and the savannas of South America. We report the first occurrence of the genus in southern Brazil (Paraná state) and the westernmost occurrence (Bolivia) of Cyatta abscondita, which extend its distribution approximately 1450 km to the west. Finally, we discuss the importance of mapping inconspicuous species in order to develop strategies for protecting endangered areas and to increase our understanding of the evolutionary history of organisms and biomes.
Yémen : des partis politiques toujours pertinents ?
Authors: Bonnefoy Laurent 
Published: October 2016

Depuis l’unification de 1990, le Yémen a été marqué par un champ partidaire dynamique et divers, donnant naissance à une formule politique originale. La phase de transition qui a suivi le soulèvement révolutionnaire de 2011 et la chute du Président Saleh a eu un effet ambivalent sur la place et le rôle des partis politiques. Elle a été marquée par une surprenante stabilité du paysage puis par une relégation apparente des formations politiques institutionnalisées, en particulier du parti al-Islah, branche yéménite des Frères musulmans. Ce processus s’est indéniablement produit au bénéfice d’acteurs armés : la rébellion houthiste, le mouvement sudiste et les jihadistes. La guerre qui a débuté en mars 2015, marquée notamment par l’implication saoudienne, semble avoir approfondi une telle dynamique de marginalisation des partis. Pourtant ce processus n’est encore une fois pas univoque. À la lumière du cas yéménite, l’objet de cet article est d’interroger le devenir et la résilience des partis dans un contexte marqué par la faillite des transitions institutionnelles, la violence et le maintien des structures autoritaires.

Les libéraux face à la libéralisation du marché politique : le Wafd au défi de la concurrence
Authors: Steuer Clément 
Published: October 2016

Représentant de la famille libérale, le Wafd est le plus ancien parti d’Égypte. Au cours des dernières années, alors que le système partisan égyptien a connu deux transformations brutales, passant d’hégémonique (1977- 2010) à bipartite (2011-2013), avant de devenir fragmenté (2015), la position du Wafd au sein de ce système s’est elle aussi modifiée. Principal parti de l’opposition légale face au PND dans les années 2000, il est devenu en 2011 le principal parti de l’opposition séculière face aux Frères musulmans et aux salafistes, mais n’est aujourd’hui que le troisième parti représenté dans un Parlement dominé par les députés indépendants. De fait, le Wafd n’a que très partiellement profité de l’importante croissance dont a bénéficié dans son ensemble le segment libéral du marché politique. Cette sous-performance s’explique par l’apparition de nouveaux concurrents, mais aussi par l’ambiguïté de sa stratégie, qui a brouillé son identité et indisposé une partie de l’électorat libéral.

Créer et identifier son périmètre informationnel : une approche de la gestion communautaire appliquée à l’agenda 21 vitrollais
Authors: Déprez Paul 
Published: October 2016

Par une analyse de la typologie des intervenants territoriaux, l’auteur propose ici une approche de la gestion communautaire, dit aussi « community management » qui consiste à repérer le cercle des « agents-facilitateurs » (Alloing et Deschamps, 2011 ; Alloing et Fayon, 2012, Alloing, 2012, 2013) sur lequel la collectivité territoriale doit s’appuyer pour « capter » et dynamiser l’information qu’elle génère. Il s’agit ainsi de démontrer qu’en amont des missions qui lui sont attribuées, le gestionnaire de communauté, dit aussi « community manager » (CM) se doit d’accompagner les acteurs d’un projet dans leur connexion au numérique.
Culture managériale versus culture en action : les dimensions régulatrices des dynamiques culturelles dans les organisations
Authors: Maas Elise 
Published: October 2016

Dans cet article, nous reviendrons sur la notion de culture organisationnelle. Pour nous, deux formes de culture semblent cohabiter dans les organisations. La « culture managériale », concept professionnel issu d’un paradigme structuraliste, est perçue par le management et les consultants comme déterministe. Utilisée dans un objectif fonctionnaliste comme un outil au service de la performance de l’organisation, elle sera assimilée à une régulation de contrôle. La « culture en action », approche scientifique socio-constructiviste de la culture, est le résultat de l’expérience et des actions collectives. Dynamique, inconsciente, symbolique et régulatrice, elle se construit et se déconstruit via les interactions des acteurs de l’organisation. Elle sera positionnée comme à l’origine de la régulation autonome. Ainsi, afin de mieux comprendre la formation, l’évolution, mais aussi les rencontres des différentes dynamiques culturelles en œuvre dans les organisations, nous observerons les interactions entre ces cultures, culture managériale et culture en action, et les règles formelles, règles de contrôle et règles autonomes, qui structurent l’agir dans l’organisation (Reynaud, 1988, 1993 ; de Terssac, 2003). Nous tenterons de positionner ces cultures, managériale et en action comme à l’origine du travail d’organisation.

Published: October 2016

La gestation pour autrui ( gpa ) est une des méthodes de procréation médicalement assistée qui pose aujourd’hui le plus question. En effet, sa légitimité est discutée tant elle bouscule toutes les représentations classiques de la famille et la parentalité. Afin de mieux comprendre ce phénomène, l’étude reprise dans cet article s’est penchée sur la motivation des mères porteuses à offrir leurs services à un couple souhaitant avoir un enfant en recourant à la gpa . Quatre femmes ont été rencontrées à qui il a été proposé de raconter la manière dont elles ont vécu cette « expérience ». La méthodologie est qualitative et comprend un entretien semi-structuré complété par deux génogrammes. Seront présentés dans cet article les principaux résultats concernant la motivation de la mère porteuse. Deux aspects ont particulièrement retenu l’attention : leur haut niveau d’empathie et la présence d’une dette au fondement de la motivation des mères porteuses.
Petit traité de navigation dans la langue migratoire
Authors: Bernardot Marc 
Published: October 2016

La métaphore liquide s’est imposée au XIX e siècle pour décrire et représenter les mouvements migratoires. Elle conduit à les traiter de manière déshumanisante en termes de canalisation, d’endiguement ou de filtrage. En Chine également, les migrants ruraux sont évoqués comme des vagues d’illégaux flottants. Les images de l’exode des Syriens l’été 2015 mettent en scène naufrages, pluies torrentielles, flaques et quête de l’eau dans les camps. De même, la vision des camps de Calais, puis Grande Synthe, dans la boue, transforme les réfugiés en victimes indifférenciées. Maniée par les migrants la métaphore de l’eau peut-elle se retourner positivement ?
Les Britanniques à Calais
Authors: Trépanier Madeleine 
Published: October 2016

Comment fonctionnent ceux qu’on appelle les Anglais dans le camp de Calais ? Les volontaires internationaux ont remplacé peu à peu les touristes dans l’animation de la ville, à partir de 2013 ; à partir de fin 2015, la mobilisation est plus forte mais toujours peu organisée. La préoccupation est de rendre le camp plus habitable, de construire avec les migrants des lieux de vie pour les femmes et les enfants, pour les repas, pour le théâtre, pour la bibliothèque. Ces hauts lieux seront épargnés de la destruction par la justice. Mais cette nouvelle urbanité n’est pas exempte de rapports de pouvoir. L’aide britannique se restructure à partir du Hangar, hors du camp, pour pratiquer l’aide sur un mode quasi-industriel par son efficacité. Les volontaires deviennent plus distants des migrants, et leur vie se déroule plutôt hors du camp. Français et Britanniques se rejoignent cependant dans le traitement des mineurs isolés et le conseil juridique.
Le site de la Linière à Grande Synthe
Authors: Hanappe Cyrille 
Published: October 2016

Le lieu de vie construit par les migrants à Grande Synthe est en cœur d’agglomération ; les exilés peuvent bénéficier des services de la ville et de nombreux services ont été installés par les associations. Il ne s’agit pas réellement d’un camp. Cette initiative s’inscrit dans le projet d’autonomie des villes par rapport aux États. Du point de vue architectural il s’agit d’un lieu ouvert capable de s’adapter aux arrivées et départs de population, capable de voir se développer des activités productives. C’est un quartier d’accueil et d’intégration.
