Abstract
The main challenges facing Oil & Gas industry is to maintain uninterrupted production, for that to preserve the assets in good condition to operate maximum attainbale life circle, thus to evade any upsets and to avoid major disastrous concerns. To achieve this objective, appropriate advanced suitable inspection methods reliable to the process / operating conditions of the assets has to be developed and implementd. Accordingly, having effective and competent inspection and maintenance management programs seems to be of significance to keep all the assets in process. Among all the inspection methods, the use of Non-Destructive Testing (NDT) methods is increasing rapidly due to their extraordinary advantages such as application easiness, high reliability, accuracy, limited time consumption, budget cost control and relatively uninterrupted productivity, which are of interest for asset management also who are involved with inspection and maintenance programs. Advanced NDT methods encourage companies to apply them for the inspection of flowlines which have the most criticality among all the processing equipments. Among all NDT methods, Radiographic Testing and Ultrasonic Testing are the most used and widely industry accepted test methods for the inspection of flowlines and assets. Any NDT methods are having own limitations, advantages and disadvantages. Hence, all NDT methods applied for the inspection on offshore production facilities has to be evaluated to see which ones have had more accurate and reliable results. The frequency of these methods is also investigated in this dissertation. Aforementioned evaluations reveal the most important influencing factors that can affect the frequency and accuracy of each particular NDT method.
Arthritis of the Knee Joint in Rheumatoid Arthritis - Evaluation of Treatment Response by Ultrasound in Daily Clinical Practice
Authors: Schäfer VS , Schmidt WA , Backhaus M , Hartung W 
Published: November 2016

Background:
Rheumatoid arthritis (RA) commonly involves the knee joint in up to 30% of patients. Musculoskeletal ultrasound enables the skilled clinician to easily assess disease activity.

Objective:

To evaluate the sensitivity to change of the sonography score of large joints in Rheumatology (SOLAR) for different treatments of knee arthritis in RA.

Method:
Joints were assessed by ultrasound at 4 visits. Laboratory, immunological and clinical parameters were recorded.

Results:
225 RA patients were analyzed. The DAS 28 in the subgroup receiving systemic steroids was significantly higher (p < 0.001) than in patients treated with intraarticular glucocorticosteroids (GCs) at T0, comparing the values from T0 to T3 the same appeared (p=0.003). Concerning the acute GC treatment regimens, the gray scale ultrasound (GSUS) sum score was found to be significantly higher in patients receiving intraarticular GCs versus no GCs (p=0,035), as well as in patients receiving systemic versus intraarticular GCs (p=0.001). Regarding the differences from T0 and T3, similar to the baseline analysis, a high GSUS sum score was significantly associated with intraarticular GCs, a low to no GC administration (p=0.035), while a high GSUS sum score was significantly linked to intraarticular GCs, rather than systemic GCs (p=0.008).

Conclusion:
SOLAR score is sensitive to change in knee arthritis. Intraarticular GC administration is performed in patients with high GSUS scores. Systemic administration of GC is linked to high disease activity (DAS28) rather than GSUS or power Doppler ultrasound (PDUS) results.

Background:Liver disease related to Hepatitis B (HBV) and C (HCV) infection has become a major cause of morbidity and mortality in HIV/AIDS patients. Data on the prevalence of HBV and HCV in Cameroon remains inconclusive.Objective:We aimed to determine the sero-prevalence and correlates of Hepatitis markers in HIV/AIDS patients in two Regional Hospitals.Methods:A cross-sectional study carried out from December 2014 to March 2015. HIV/AIDS patients aged 21 were included and above, receiving care at HIV treatment centres. Data was collected using a structured questionnaire. Blood samples were collected to screen for Hepatitis with HBsAg and anti HCV antibody rapid immunochromatographic test kits. Correlates of hepatitis were investigated by logistic regression. STATA was used for data analysis.Results:We included 833 HIV/AIDS patients,78.8% (657) were female. Mean age was 44(SD 11) years. Prevalence of Hepatitis in general (total of two viral markers tested) was 8.9% (74/833), with 6.1% for HBsAg and 2.8% for Anti-HCV antibodies. From multivariate analysis, the likelihood of having hepatitis was independently increased by a history of surgical interventions [OR: 1.82(1.06-3.14)], and of sexually transmitted infections [OR: 2.20(1.04-4.67)].Conclusion:Almost one in ten participants with HIV/AIDS attending the BRH and LRH tested positive for either HBsAg or anti HCV antibodies. Screening for HBV and HCV should therefore be integrated to the existing guidelines in Cameroon as it can influence management. More studies are needed to evaluate the extent of liver disease and magnitude of HIV suppression in hepatitis and HIV coinfection in this setting.
Foucault and Deleuze: Making a Difference with Nietzsche
Authors: Grace Wendy 
Published: November 2016

Michel Foucault and Gilles Deleuze are regarded as French “Nietzscheans” par excellence. By drawing attention to the articulation of “difference” in contemporary thought, this paper attempts to go beyond the label ‘Nietzschean’ in an effort to discern two distinct philosophical trajectories inspired by Nietzsche. I suggest that Deleuze reads Nietzsche as an empiricist whose philosophy of nature critically undermines representational modes of thought from Plato to Hegel and beyond. Difference is therefore given in itself. Foucault, on the other hand, reads Nietzsche primarily as a historian of culture, whose radical reflection on language pushes philosophy into new interpretative forms of analysis that seriously confronts the role of political power in the production of truth. Difference is thus invented and only known within the contours of these fabrications. While no judgement is made about the accuracy or otherwise of their respective interpretations of Nietzsche, this paper implicitly asks whether a Nietzschean genealogical ethos can inform those political struggles today for which the meaning of difference is contested.
Ethnographies of Neoliberal Governmentalities: from the neoliberal apparatus to neoliberalism and governmental assemblages
Authors: Brady Michelle 
Published: November 2016

This article is aimed at Foucauldian scholars and seeks to introduce them to ethnographic works that interrogate neoliberal governmentalities. As an analytic category ‘neoliberalism’ has over the last two decades helpfully illuminated connections between seemingly unrelated social changes occurring at multiple scales. Even earlier —in his College de France 1978-9 Birth of Biopolitics lectures, to be precise—Foucault began his engagement with neoliberalism as a dominant political force. Despite being more than three decades old, Foucault’s analysis of neoliberal rationalities remains fresh and insightful, which perhaps explains why scholars inspired by his analytics of governmentality have been able to make major contributions to the current social science literature on neoliberalism. However, there are increasing concerns that governmentality scholars succumb to a more general tendency among social scientists to present neoliberal transformations in monolithic and linear terms. This article critically reviews contributions from a small but growing group of neo-Foucauldian researchers that avoid these tendencies. These researchers investigate the changes wrought by neoliberalism through methodologies that involve combining an analytics of governmentality with ethnographic and quasi-ethnographic methods, and in doing so they avoid deterministic, homogenous and static accounts of social transformation. By beginning with the “everyday,” these works reject the idea that neoliberal governmentality forms a coherent apparatus. Instead these ethnographies of neoliberal governmentalities focus on governmental ensembleges (or assemblages) that link neoliberal political rationalities with non-liberal rationalities, and they explore how neoliberal thought and practice is transformed across time and space.
Spotting the Primacy of Resistance in the Virtual Encounter of Foucault and Deleuze
Authors: Checchi Marco 
Published: November 2016

Foucault’s intuition that resistance comes first challenges the theses of the co-originality of power and resistance or the superiority of power over resistance. In order to transform this intuition into the concept of the primacy of resistance, the article uses Deleuze’s ontology and in particular the idea of the virtual. According to Deleuze, resistance displays a privileged relation with the virtual, understood as the ontological region animated by all the potentialities that might be or might have been actualised. As such, resistance is presented as a creative and affirmative force, provoking reactions and forcing power to change. Nietzsche’s divide between active and reactive forces serves to set up a qualitative distinction between resistance and power. Power relations are therefore understood as the interplay of the creative affirmation of resistance and the subsequent reaction of power. The primacy of resistance allows us to elaborate a dynamic model of power relations whose mechanism evokes Tronti’s interpretation of Marxism structured upon the primacy of labour and workers’ struggle over capital.
Eliminating the Form 20-F Reconciliation and Audit Pricing
Authors: Lin Yi-Hung , Huang Hua-Wei (Solomon) 
Published: November 2016

ABSTRACT
This study examines the impact of the Securities and Exchange Commission's (SEC) policy in 2007 to eliminate the Form 20-F reconciliation requirements for foreign cross-listed firms following the International Financial Reporting Standards (IFRS) on audit pricing. We find that the elimination of this requirement decreases audit fees, and this fee decrease is less prominent when foreign cross-listed firms engage industry-specialist auditors. Our findings reinforce prior studies that found that managers of foreign cross-listed firms have a greater tendency to manage earnings when there is a need to reconcile earnings (Bradshaw, Bushee, and Miller 2004; Lang, Raedy, and Wilson 2006; Kang, Krishnan, Wolfe, and Yi 2012), and thus eliminating the Form 20-F reconciliation impedes managerial manipulation of earnings, decrease financial reporting risk, and audit fees. The results also provide direct evidence to support the SEC's (2007) claim that eliminating the Form 20-F reconciliation would reduce the preparation costs and regulatory burdens for foreign issuers.
MULTI-SPACECRAFT ANALYSIS OF ENERGETIC HEAVY ION AND INTERPLANETARY SHOCK PROPERTIES IN ENERGETIC STORM PARTICLE EVENTS NEAR 1 au
Authors: Ebert R. W. , Dayeh M. A. , Desai M. I. , Jian L. K. , Li G. , Mason G. M. 
Published: November 2016

ABSTRACT
We examine the longitude distribution of and relationship between interplanetary (IP) shock properties and ∼0.1–20 MeV nucleon−1 O and Fe ions during seven multi-spacecraft energetic storm particle (ESP) events at 1 au. These ESP events were observed at two spacecraft and were primarily associated with low Mach number, quasi-perpendicular shocks. Key observations include the following: (i) the Alfvén Mach number increased from east to west of the coronal mass ejection source longitude, while the shock speed, compression ratios, and obliquity showed no clear dependence; (ii) the O and Fe time intensity profiles and peak intensities varied significantly between longitudinally separated spacecraft observing the same event, the peak intensities being larger near the nose and smaller along the flank of the IP shock; (iii) the O and Fe peak intensities had weak to no correlations with the shock parameters; (iv) the Fe/O time profiles showed intra-event variations upstream of the shock that disappeared downstream of the shock, where values plateaued to those comparable to the mean Fe/O of solar cycle 23; (v) the O and Fe spectral index ranged from ∼1.0 to 3.4, the Fe spectra being softer in most events; and (vi) the observed spectral index was softer than the value predicted from the shock compression ratio in most events. We conclude that while the variations in IP shock properties may account for some variations in O and Fe properties within these multi-spacecraft events, detailed examination of the upstream seed population and IP turbulence, along with modeling, are required to fully characterize these observations.
THE UNRELAXED DYNAMICAL STRUCTURE OF THE GALAXY CLUSTER ABELL 85

Published: November 2016

ABSTRACT
For the first time, we explore the dynamics of the central region of a galaxy cluster within r
500 ∼ 600 h−1 kpc from its center by combining optical and X-ray spectroscopy. We use (1) the caustic technique, which identifies the cluster substructures and their galaxy members with optical spectroscopic data, and (2) the X-ray redshift fitting procedure, which estimates the redshift distribution of the intracluster medium (ICM). We use the spatial and redshift distributions of the galaxies and of the X-ray-emitting gas to associate the optical substructures to the X-ray regions. When we apply this approach to Abell 85 (A85), a complex dynamic structure of A85 emerges from our analysis: a galaxy group, with redshift z = 0.0509 ± 0.0021 is passing through the cluster center along the line of sight dragging part of the ICM present in the cluster core; two additional groups, at redshift z = 0.0547 ± 0.0022 and z = 0.0570 ± 0.0020, are going through the cluster in opposite directions, almost perpendicularly to the line of sight, and have substantially perturbed the dynamics of the ICM. An additional group in the outskirts of A85, at redshift z = 0.0561 ± 0.0023, is associated with a secondary peak of X-ray emission, at redshift

. Although our analysis and results on A85 need to be confirmed by high-resolution spectroscopy, they demonstrate how our new approach can be a powerful tool to constrain the formation history of galaxy clusters by unveiling their central and surrounding structures.
RADIO-LOUD AND RADIO-QUIET QSOs

Published: November 2016

ABSTRACT
We discuss 6 GHz JVLA observations covering a volume-limited sample of 178 low-redshift (

) optically selected quasi-stellar objects (QSOs). Our 176 radio detections fall into two clear categories: (1) about 20% are radio-loud QSOs (RLQs) with spectral luminosities of

that are primarily generated in the active galactic nucleus (AGN) responsible for the excess optical luminosity that defines a bona fide QSO; and (2) the remaining 80% that are radio-quiet QSOs (RQQs) that have

and radio sizes

, and we suggest that the bulk of their radio emission is powered by star formation in their host galaxies. “Radio-silent” QSOs (

) are rare, so most RQQ host galaxies form stars faster than the Milky Way; they are not “red and dead” ellipticals. Earlier radio observations did not have the luminosity sensitivity of

that is needed to distinguish between such RLQs and RQQs. Strong, generally double-sided radio emission spanning

was found to be associated with 13 of the 18 RLQ cores with peak flux densities of

(

). The radio luminosity function of optically selected QSOs and the extended radio emission associated with RLQs are both inconsistent with simple “unified” models that invoke relativistic beaming from randomly oriented QSOs to explain the difference between RLQs and RQQs. Some intrinsic property of the AGNs or their host galaxies must also determine whether or not a QSO appears radio-loud.
TRACING SLOW WINDS FROM T TAURI STARS VIA LOW-VELOCITY FORBIDDEN LINE EMISSION

Published: November 2016

ABSTRACT
Using Keck/HIRES spectra (Δ v ∼ 7 km s−1) we analyze forbidden lines of [O i] 6300 Å, [O i] 5577 Å and [S ii] 6731 Å from 33 T Tauri stars covering a range of disk evolutionary stages. After removing a high-velocity component (HVC) associated with microjets, we study the properties of the low-velocity component (LVC). The LVC can be attributed to slow disk winds that could be magnetically (magnetohydrodynamic) or thermally (photoevaporative) driven. Both of these winds play an important role in the evolution and dispersal of protoplanetary material. LVC emission is seen in all 30 stars with detected [O i] but only in two out of eight with detected [S ii], so our analysis is largely based on the properties of the [O i] LVC. The LVC itself is resolved into broad (BC) and narrow (NC) kinematic components. Both components are found over a wide range of accretion rates and their luminosity is correlated with the accretion luminosity, but the NC is proportionately stronger than the BC in transition disks. The full width at half maximum of both the BC and NC correlates with disk inclination, consistent with Keplerian broadening from radii of 0.05 to 0.5 au and 0.5 to 5 au, respectively. The velocity centroids of the BC suggest formation in an MHD disk wind, with the largest blueshifts found in sources with closer to face-on orientations. The velocity centroids of the NC, however, show no dependence on disk inclination. The origin of this component is less clear and the evidence for photoevaporation is not conclusive.
EFFECTS OF PROXIMA CENTAURI ON PLANET FORMATION IN ALPHA CENTAURI
Authors: Worth R. , Sigurdsson S. 
Published: November 2016

ABSTRACT
Proxima Centauri is an M dwarf approximately 15,000 au from the Alpha Centauri binary, comoving and likely in a loosely bound orbit. Dynamic simulations show that this configuration can form from a more tightly bound triple system. As our nearest neighbors, these stars command great interest as potential planet hosts, and the dynamics of the stars govern the formation of any planets within the system. Here we present a scenario for the evolution of Alpha Centauri A and B and Proxima Centauri as a triple system. Based on N-body simulations, we determine that this pathway to formation is plausible, and we quantify the implications for planet formation in the Alpha Centauri binary. We expect that this formation scenario may have truncated the circumstellar disk slightly more than a system that formed in the current configuration, but that it most likely does not prevent terrestrial planet formation. We simulate planet formation in this system and find that, in most scenarios, two or more terrestrial planets can be expected around either Alpha Centauri A or B, orbiting in a region out to approximately 2 au, assuming that planetesimals and planetary embryos are able to form in the system first. Additionally, terrestrial planet formation and stability in Proxima Centauri’s habitable zone are also plausible. However, an absence of planets around these stars may be indicative of highly disruptive stellar dynamics in the past.
THE INTERMEDIATE NEUTRON-CAPTURE PROCESS AND CARBON-ENHANCED METAL-POOR STARS
Authors: Hampel Melanie , Stancliffe Richard J. , Lugaro Maria , Meyer Bradley S. 
Published: November 2016

ABSTRACT
Carbon-enhanced metal-poor (CEMP) stars in the Galactic Halo display enrichments in heavy elements associated with either the s (slow) or the r (rapid) neutron-capture process (e.g., barium and europium, respectively), and in some cases they display evidence of both. The abundance patterns of these CEMP-s/r stars, which show both Ba and Eu enrichment, are particularly puzzling, since the s and the r processes require neutron densities that are more than ten orders of magnitude apart and, hence, are thought to occur in very different stellar sites with very different physical conditions. We investigate whether the abundance patterns of CEMP-s/r stars can arise from the nucleosynthesis of the intermediate neutron-capture process (the i process), which is characterized by neutron densities between those of the s and the r processes. Using nuclear network calculations, we study neutron capture nucleosynthesis at different constant neutron densities n ranging from 107–1015 cm−3. With respect to the classical s process resulting from neutron densities on the lowest side of this range, neutron densities on the highest side result in abundance patterns, which show an increased production of heavy s-process and r-process elements, but similar abundances of the light s-process elements. Such high values of n may occur in the thermal pulses of asymptotic giant branch stars due to proton ingestion episodes. Comparison to the surface abundances of 20 CEMP-s/r stars shows that our modeled i-process abundances successfully reproduce observed abundance patterns, which could not be previously explained by s-process nucleosynthesis. Because the i-process models fit the abundances of CEMP-s/r stars so well, we propose that this class should be renamed as CEMP-i.
BEYOND THE MALTESE CROSS: GEOMETRY OF TURBULENCE BETWEEN 0.2 AND 1 au
Authors: Verdini Andrea , Grappin Roland 
Published: November 2016

ABSTRACT
The spectral anisotropy of turbulent structures has been measured in the solar wind since 1990, relying on the assumption of axisymmetry about the mean magnetic field, B
0. However, several works indicate that this hypothesis might be partially wrong, thus raising two questions: (i) is it correct to interpret measurements at 1 au (the so-called Maltese cross) in term of a sum of slab and two-dimensional (2D) turbulence; and (ii) what information is really contained in the Maltese cross? We solve direct numerical simulations of the magnetohydrodynamic equations including the transverse stretching exerted by the solar wind flow and study the genuine 3D anisotropy of turbulence as well as that one resulting from the assumption of axisymmetry about B
0. We show that the evolution of the turbulent spectrum from 0.2 to 1 au depends strongly on its initial anisotropy. An axisymmetric spectrum with respect to B
0 keeps its axisymmetry, i.e., resists stretching perpendicular to radial, while an isotropic spectrum becomes essentially axisymmetric with respect to the radial direction. We conclude that close to the Sun, slow-wind turbulence has a spectrum that is axisymmetric around B
0 and the measured 2D component at 1 au describes the real shape of turbulent structures. In contrast, fast-wind turbulence has a more isotropic spectrum at the source and becomes radially symmetric at 1 au. Such structure is hidden by the symmetrization applied to the data that instead returns a slab geometry.
