Simultaneous Capillary Pressure and Wettability Determination for Tight Bakken Cores Using an Ultra-High-Speed Centrifuge
Authors: Luo Peng , Li Sheng 
Published: February 2017

Abstract
Capillary pressure and wettability play crucial roles in controlling fluid flow and distribution in tight/shale reservoirs with its nano- to micrometer-scale pore sizes, such as the Bakken formation in the Williston Basin. Because wettability reflects the interactions between rock surfaces and fluids, the introduction of external fluids during drilling, completion, and enhanced oil recovery processes may possibly alter wettability through chemical adsorption on rock surfaces. Therefore, accurate determination of Bakken formation wettability, particularly its alteration caused by different injection fluids, is extremely important in the Bakken production process. In this study, a state-of-the-art ultra-high-speed centrifuge was employed to measure capillary pressures and examine the wettability of Bakken cores by calculating the USBM (United States Bureau of Mines) wettability indices. Cores saturated and aged with formation brine or surfactant solutions were first injected with Bakken crude oil (i.e., drainage process). Then the fluids in the cores were displaced by brine or surfactant solutions to obtain the imbibition capillary pressure curve. Multi-speed measurements were conducted using the centrifuge to determine the capillary pressure between the crude oil and brine/surfactant solutions. Wettability and its alteration after surfactant saturation were quantified by analyzing different sets of wettability indices calculated from capillary pressure curves. The experimental results revealed that wettability alteration caused by surfactant adsorption on rock surfaces tended to change the rocks from water-wet to a more neutral-wet status, while the aging process partially restored the cores to water-wet again.
For unconventional tight cores such as Bakken, the ultra-high-speed centrifuge method presents several distinct advantages over the commonly used mercury injection capillary pressure (MICP) method combined with other wettability measurement methods: (1) actual reservoir oil and brine are used, so that results are more representative of field conditions; (2) it is a non-destructive method so that core plugs can be reused to study wettability alteration caused by chemical additives; and (3) capillary pressure, wettability, and relative permeability can be obtained from the same set of measurements.

Summary
To profoundly investigate the flow behavior and viscous-oil-microdisplacement characteristics of hydrophobically modified partially hydrolyzed polyacrylamides (HMHPAMs) as well as the effect of associating monomer content on those behaviors and characteristics, compared with partially hydrolyzed polyacrylamide (HPAM), the flow experiments through three serial mounted flat-sand-inclusion micromodels and the viscous-oil-microdisplacement experiments in both homogeneous and interstratified connected heterogeneous repeatable quantitative visualization micromodels were conducted by use of a series of polymers with varied associating monomer content (0–1.0 mol%) at similar viscosity within all shear rates concerned. The results obtained from flow experiments show that the resistance factors (RFs) and residual resistance factors (RRFs) generated by HMHPAMs were noticeably higher than those of HPAM, and the RFs and RRFs exhibited significant permeability dependence and increased with associating monomer content. The greater RFs and RRFs for associative polymer might not be mainly caused by polymer adsorption or retention but mostly caused by increasing aggregate sizes. At concerned permeabilities (1.1–6.1 µm2), all injections of HMHPAMs could tend to be stable, which indicates that all HMHPAMs could propagate deep into the porous media. The viscous-oil-microdisplacement experiments regarding the visualization micromodels with varied permeabilities (and permeability contrasts) provide new insights into the viscous-oil-microdisplacement characteristics of HMHPAMs, such as the piston-like displacement and profile modification. In homogeneous models, under different permeabilities (1.1–6.1 µm2), the variations of final viscous-oil recovery first increased and then decreased as a function of increasing hydrophobe content, and the hydrophobe content of the polymer to obtain maximum oil recovery enhanced with increasing permeability. This might qualitatively indicate that a constant permeability matches an optimal content of hydrophobic groups. At permeability contrast of approximately three, the HMHPAM with lower hydrophobe content (0.2 mol%) could obtain the maximum viscous-oil recovery. In contrast, the maximum viscous-oil recovery was achieved by the HMHPAM with higher hydrophobe content (1.0 mol%) at a contrast of approximately five. The HMHPAM with higher content of hydrophobic groups is suitable for the significant heterogeneity.

Published: February 2017

The Paralympic sport has become an important tool for post-traumatic recovery, adaptation, integration and social inclusion of people with disabilities. Disabled people involvement into sports activities has important social implications not only for a person but also for society as a whole. Due to relative "youth" of the Paralympic sports, there are no enough studies aimed at creation of necessary scientific support not only for full-scale trainings and competitions of Paralympic athletes, but also for provision of full integration of Paralympians into society with the means of the Paralympic Sports, which is extremely important. High importance of psychological and socio-psychological research in this context is obvious. The article presents the results of our research aimed at identifying of common characteristics and factors of Paralympic athletes’ self-realization in order to promote the efficiency of trainings and competitions and full-scale integration into society

Authors: Digiacomo Maria , Sartini Stefania , Nesi Giulia , Sestito Simona , Coviello Vito , La Motta Concettina , Rapposelli Simona 
Published: February 2017

Background:
Aldose reductase, the first enzyme of the polyol pathway, is the key determinant for the pathogenesis of long term diabetic complications. Accordingly, its inhibition represents the major therapeutic strategy to treat this kind of pathologies.

Objectives:
In this work we describe the synthesis and the functional evaluation of a number of spiro-oxazolidinone and spiro-morpholinone acetic acid derivatives, and their benzyloxy analogs, developed as aldose reductase inhibitors.

Results:
Most of them proved to inhibit the target enzyme, showing IC50 values in the micromolar/low micromolar range. SARs observed among the three different series allowed to highlight their key pharmacophoric elements, thus creating sound basis for the design of novel and more effective inhibitors.

Conclusion:
Although further substitution patterns are needed, the novel compounds here proposed represent a good starting point for the development of novel and effective ARIs.
The Real Effects of Mandatory Quarterly Reporting
Authors: Ernstberger Jürgen , Link Benedikt , Stich Michael , Vogler Oliver 
Published: February 2017

ABSTRACT
This paper examines how mandatory quarterly reporting affects managers' business decisions in terms of real activities manipulations. For our analyses, we use the setting of the European Union, where the reporting frequency was increased with the introduction of a mandate to issue Interim Management Statements (IMSs) on a quarterly basis. Controlling for accrual-based earnings management, we find an increase in real activities manipulations for firms mandated to switch from semiannual to quarterly IMS reporting, relative to matched control firms. This finding is in line with the notion of higher managerial short-termism resulting from increased reporting frequency requirements. Further, we provide evidence that reporting frequency-induced real activities manipulations are more pronounced if the price pressure from investors is high and if the informativeness of IMS disclosure is low. We also document that reporting frequency-induced real activities manipulations are followed by a short-term increase and then a decrease in firms' operating performance.

Authors: Barkhi Reza , Kozlowski Stephen 
Published: February 2017

ABSTRACT
Three short exercises are presented that introduce certain functional aspects of Enterprise Resource Planning (ERP) software. The objective is to provide students with an introduction to the functionality that is incorporated in a typical ERP software solution that supports an evaluation of internal controls and segregation of duties as part of the Information Technology Audit (IT Audit) function. We have developed three hands-on step-by-step exercises using a widely implemented ERP system (i.e., SAP) and provide access to SAP on the cloud so that students can learn how to verify internal controls embedded in the system and identify control weaknesses such as a lack of segregation of duties.
Exercising Due Diligence in Studies of Duration of Competitive Advantage Due to Emerging Technology Adoption
Authors: Stratopoulos Theophanis C. 
Published: February 2017

ABSTRACT
Motivated by the study of Reinking et al. (2015), the study proposes a due diligence process for future studies aiming to investigate the duration of competitive advantage due to emerging technology adoption. The proposed process is based on the following premise: Predictions related to rate of adoption are useful to IT business value researchers because technology adoption remains a potential source of competitive advantage until adoption rate has reached approximately 50 percent. Based on a comparison of two technologies (ERP and e-commerce), the study provides the following three recommendations for researchers interested in productivity and financial performance-related payoffs due to emerging technology adoption: (1) apply the resource-based view analysis on the emerging technology to see if the duration of competitive advantage is worth exploring; (2) leverage the synthesis done by Stratopoulos (2016) to develop an a priori testable benchmark duration; and (3) contrast adopters with a matched sample of non-adopters or late adopters to establish a duration advantage.
Busy Auditors, Partner-Client Tenure, and Audit Quality: Evidence from an Emerging Market
Authors: Gul Ferdinand A. , Ma Shuai (Mark , Lai Karen 
Published: February 2017

ABSTRACT
Using a sample of public firms listed in the Chinese market for the years 2000–2009, we find that audit partners with more public clients are associated with lower audit quality, consistent with the “busyness” effect that auditing multiple clients dissipates audit partner effort and, thus, reduces audit quality. However, the negative association is more pronounced for auditors with short audit partner-client tenure, supporting the idea that the lack of client-specific knowledge exacerbates the busyness effect. Collectively, these findings contribute to a better understanding of audit partner behavior in an emerging market.

Some test about Capital Asset Pricing Model (CAPM) are in fact, most of them showed that there were in equilibrium between the CAPM theory with the empirical facts. This in equilibrium most can be see in the intercept which is not the same as zero. Some tests are resulting that linear relation between the return level which can be hoped by the risk which is measured with beta, but in the other fact shows that there is still factor or variable beside beta which influence the return of security, those variables are not explained by CAPMThe failure of empirical test for proving the CAPM hyphotesis are caused by the failure of the L""'APM specification itself then the use of market model which maybe is not relevant because of the return fluctuation and the free investment risk The investment process in security is doing evaluation to the investment performance, in security investment which is often done in portofolio form, so it is needed portofolio performance l!valuation.

De la naissance de l’OTASE à l’accord de paix sur le Cambodge : la France, la Grande-Bretagne et la sécurité en Asie du Sud-Est pendant la Guerre froide
Authors: Journoud Pierre 
Published: February 2017

Entre 1954 et 1991, la France et la Grande-Bretagne ont joué un rôle important, bien qu’en partie éclipsé par les États-Unis, dans la sécurité collective en Asie du Sud-Est, au carrefour entre décolonisation, Guerre froide et conflits armés régionaux. Elles se sont impliquées dans des organisations multilatérales à vocation stratégique ; elles ont participé à des négociations délicates et favorisé, malgré bien des échecs, de longs processus de paix. Leurs tentatives communes ou séparées de modérer les États-Unis dans les conflits du Sud-Vietnam et du Laos, particulièrement entre 1954 et 1962, leur capacité à peser dans la résolution de conflits régionaux armés, surtout le conflit cambodgien dans les années 1980, ont conduit ces puissances à renforcer leur dialogue politique bilatéral sur la région, mais aussi à sensibiliser la CEE à la nécessité d’adopter une position commune sur le conflit cambodgien et de renforcer son dialogue interrégional avec l’ASEAN.
Les études européennes, un outil pour développer les relations entre le Vietnam et l’Union européenne
Authors: Quang Minh Pham 
Published: February 2017

Les relations entre le Vietnam et l’Europe remontent à quatre siècles, avec l’arrivée des premiers missionnaires européens dans le pays. Les relations bilatérales actuelles ne reflètent cependant pas cette tradition et sont insatisfaisantes des deux côtés. Où situer ce qui fait obstacle entre ces deux partenaires ? Pourquoi ces malentendus dans leurs relations ? L’article analyse d’un point de vue historique le développement des études européennes au Vietnam à l’aide d’une information vietnamienne de première main. Sa thèse centrale est que, pour promouvoir les relations entre le Vietnam et l’Europe, les études européennes au Vietnam doivent être une priorité sur les agendas de part et d’autre. Le manque d’information et d’instruction adéquate peut influencer considérablement leur coopération. L’article conclut que les relations Union européenne-Vietnam se renforceront à coup sûr, car elles sont une vieille tradition pour le Vietnam, et que les programmes d’études européennes sont un instrument de nature à mieux faire comprendre l’UE dans ce pays.

Abstract
The prevalence of neurodegenerative disease and arthritis increases with age. Despite both processes being associated with immune activation and inflammation, little is known about the mechanistic interactions between neurodegenerative disease and arthritis. In this article, we show that tau-transgenic (tau-tg) mice that develop neurodegenerative disease characterized by deposition of tau tangles in the brain are highly susceptible to developing arthritis. Already at steady-state conditions, tau-tg mice exhibit peripheral immune activation that is manifested by higher numbers of granulocytes, plasmablasts, and inflammatory Ly6Chi CCR2+ monocytes, as well as increased levels of proinflammatory cytokines, such as TNF-α and IL-17. Upon induction of collagen-induced arthritis (CIA), tau-tg mice displayed an increased incidence and an earlier onset of CIA that was associated with a more pronounced inflammatory cytokine response. Furthermore, induction of CIA led to significantly elevated numbers of Iba-1–expressing cells in the brain, indicative of microglia activation, and the formation of anti-tau Abs in tau-tg mice. These changes were accompanied by the resolution of tau tangles and significantly decreased neurodegenerative pathology. In summary, these data show that neurodegenerative disease enhances the development of arthritis. In addition, arthritis, once induced, triggers innate immune responses in the brain, leading to resolution of neurodegenerative changes.
