Petrophysical Joint Inversion for Reservoir Saturation Mapping: A Case Study
Authors: Alsaif Sarah , Marsala Alberto 
Published: June 2017

Abstract
Accurately estimating the fluid distribution in the reservoir is a key challenge in the oil industry. Well-log measurements are used to quantitatively characterize subsurface properties such as porosity and fluid saturation. It was proven that it is possible to reduce the ambiguity of the interpretation of well-log measurements by examining a common set of petrophysical parameters that relate geophysical attributes to rock properties. Simultaneously conciliating acoustic velocity, density and electrical conductivity jointly in the interpretation of well logs and deep interwell measurements can significantly reduce the uncertainty of the interpretation and improve the prediction of the reservoir properties, such as saturation.
This study examines a Bayesian joint inversion approach linking rock properties with well-log measurements through constitutive equations. The procedure is applied on actual formation evaluation measurements from a carbonate reservoir in Saudi Arabia.
Productivity Enhancement from Acidizing Horizontal Wells Drilled in Thin Carbonate Reservoir Layers
Authors: Varela-Pineda Alfonso , Fhami Aulia , Al-Abdullah Hassan M. , Muslim Hassan 
Published: June 2017

Abstract
This paper presents a careful integration of geomechanical and reservoir properties to avoid excessive fracture extension and achieve proper acid containment within a thin reservoir layer, yielding very successful results. In general, wells drilled in thin reservoir layers may not produce or sustain continuous production for an extended period, even though the reservoir may have good oil saturation and pressure support. Log derived mechanical properties and empirical correlations from lab test performed on numerous core plugs were compiled for geomechanical modeling. In addition to the density log integration, the dynamic and static mechanical properties were utilized to estimate the maximum and minimum horizontal stresses. The fracture gradient, wellhead injection pressure, acid volumes and operational requirements were determined to properly design the acid job to avoid fracturing the reservoir beyond its thickness, but effectively establishing communication between the reservoir and the bore hole. Well data gathering such as completion type, intervals to be acidized, and reservoir pressure were also incorporated during the workflow process. The approach was piloted in two wells.
The productivity improvement from the acidizing job for the cases presented, show effective results in terms of near-wellbore formation damage removal and flow capacity improvement. The selected wells, former intermittent producers, responded favorably to the acid pumped with a considerable increase in oil production. Water cut did not initially increase, reflecting the effective avoidance of fracture creation to connect to lower aquifer zones. The validity of the log derived mechanical properties and stress profiles, as well as the lab derived correlations confirmed the validity of properly characterizing the reservoir in terms of strength and stiffness.
Production improvement, modelling process and treatment have been captured and shared in this manuscript.
Establishment and application of three-dimensional realistic river terrain in the numerical modeling of flow over spillways
Authors: Qi Lan , Chen Hui , Wang Xiao , Fei Wencai , Liu Donghai 
Published: June 2017

AbstractWe present an integrated three-dimensional (3D) spillway model where the realistic and complicated river terrain is implemented by the platform CATIA (Computer Aided Three Dimensional Interactive Application). This integrated 3D spillway model allows for complicated topographic and geomorphic conditions and describes the spatial distribution of the spillway dam (upstream reservoir, downstream river channel and the spillway dam itself) precisely, thus making it a real alternative to the physical model. Furthermore, this model provides the premise and possibility of a full-scale simulation of the spillway flow, that is, it can not only be used to study the hydraulics on the spillway face, but also can be used to study the hydraulics along the downstream river channel and estimate the scour problem associated with both the spillway flow and downstream river channel. In this model, turbulence was simulated using RNG k−ɛ equations. The flow velocity and surface pressure from the numerical model were verified by the data from experiments. Moreover, the river flow was studied and flow velocities downstream were obtained. The scour formed downstream of a ski-jump was also studied in this study on the location and shape of a scour hole. In all, this study provides new approaches for solving relevant hydraulic engineering problems.

EMANCIPAZIONE FEMMINILE IN GRECIA E INFLUENZE STRANIERE. IL CASO DI KALLIRROI PARREN
Authors: Boubara Ada 
Published: June 2017

The purpose of this paper is to examine the early beginnings of women’s emancipation in Greece. The rise of such a new consciousness was undoubtedly slow in the Greek context as the four century Ottoman rule had placed the female figure in a clearly subservient and passive role. The main focus of the essay is on the admirable writings and social activities of Kallirroi Parren, one of those Greek pioneering women who devoted their lives to the improvement of the position of the woman in a community still so largely connected with the past and not yet prepared to accept changes. Kallirroi Parren was fully aware of such boundaries and claimed for a moderate authonomy. Furthermore, the essay draws a parallel between the characters of Parren’s most meaningful book, Η Χειραφετημένη (The Emancipated Woman), with some of the characters described by Angelica Palli Bartolommei in her Racconti (Short Stories). The aim is to demonstrate how these distinguished women – one Greek and the other of Greek origin, whose family had moved to Italy – were sharing the same view on women’s rights although dwelling in different countries. In other words, two distinctive personalities but one single voice. The study ends by quoting the date and the causes of Parren’s death in order to honor the life of a woman who paved the way of women’s liberation in Greece, a path which was later followed by many other women who, like the great Cretean, made of such a battle a way of life.
EL DOBLE Y SU SUBVERSIÓN EN EL CORAZÓN DEL TÁRTARO DE ROSA MONTERO
Authors: García Armero Carmen 
Published: June 2017

Una lectura literal de El corazón del tártaro (2001) de Rosa Montero podría darnos la impresión de que solo se narra el acoso sufrido por Sofía Zarzamala a manos de su hermano gemelo y el proceso de maduración por el que atraviesa la protagonista. Sin embargo, una lectura interdisciplinaria y psicoanalítica revela que nos encontramos ante una novela de doppelgänger, en la que el enfrentamiento de la protagonista con su doble no finaliza con su desintegración, sino con la posibilidad de alcanzar una personalidad integrada. A través de este personaje femenino, Montero cuestiona y subvierte la tradición literaria del doble. Palabras clave: doble, individuación, identidad, género, poder, patriarcado, memoria y tradición. The Double and its Subversion in El Corazón del Tártaro by Rosa Montero Abstract: A literal reading of El corazón del tártaro (2001) by Rosa Montero could give us the impression that the novel just narrates the harassment inflicted on Sofía Zarzamala by her twin brother and the process of maturity that the main character goes through. However, an interdisciplinary and psychoanalytic approach reveals that this narrative can be read as a doppelgänger novel. The protagonist’s confrontation with her double does not end with her disintegration, but with the possibility of achieving an integrated personality. Through this feminine character, Montero questions and subverts the literary tradition of the double. Key words: double, individuation, identity, gender, power, patriarchy, memory and tradition.
ELENA E L’ALIBI DELLA VIOLENZA
Authors: Brescia Graziana 
Published: June 2017

Riassunto: Lo scambio di lettere tra Elena e Paride nelle Eroidi di Ovidio rappresenta una nuova fase all'interno dell'ampia ricezione dell'episodio mitico del rapimento di Elena. Ovidio riscrive la storia dei due amanti sulla base del codice elegiaco, centrandosi specificatamente nel momento della seduzione da parte di Paride e riconfigurando le funzioni del sequestratore e della donna sedotta alla luce tanto dell'Ars amatoria come della tradizione giuridica. L'innocenza di Elena e il suo ruolo di vittima - e non complice- del raptus sono conferiti dall'uso di vis a nome di Paride, anche se - come il poeta spiega nella sua Ars- la violenza è solo simulata e, soprattutto, grata puellis.Parole chiave: Ovidio, Elena, Paride, abduzione, violenza, simulazione, complicità. Elena and the Alibi of Violence (Ovidio, Heroides 16-17)Abstract: The letter exchange between Helen and Paris in Ovid’s Heroides is a new step in the long-standing reception of the mythical episode of the abduction of Helen. Ovid re-writes the story of the two lovers according to the elegiac code, focusing specifically on the seduction by Paris and re-shaping the roles of the abductor and the seduced woman in the light of both the Ars amatoria and the juridical tradition. Helen’s innocence and her role of victim – and not accomplice – of the raptus are granted by the use of vis on behalf of Paris, even if – as the poet teaches in his Ars – the violence is just simulated and, most of all, grata puellis.Key words: Ovid, Helen, Paris, abduction, violence, simulation, complicity.

Authors: Ozsoy Iskender , Mimaroglu Abdullah , Unal Huseyin 
Published: June 2017

Abstract
In this study, the tribological behavior of epoxy composites was experimentally studied and analytically modeled using finite element techniques. Wear test and modeling were carried out for pin-on-disk configuration and under identical boundary and test conditions. The tribological elements consisted of Al2O3 filled epoxy composite pin and a steel disk. The tribological system was modeled two-dimensionally and a quasi-static analysis was performed. The wear amount and the developed stresses during the rubbing process were predicted and compared with the experimentally determined results. A good correlation between the experimental and analytical results were observed.
L’influence française dans les Pays-Bas autrichiens : le cas de la représentation des étrangers au Théâtre de la Monnaie au XVIIIe siècle

De Franse invloed in de Oostenrijkse Nederlanden : het geval van de voorstelling van de vreemdelingen in de Muntschouwburg in de achttiende eeuw
Dit artikel analyseert het beeld van de niet-Europese vreemdeling in de stukken van de achttiende eeuw in de Muntschouwburg te Brussel. Het betreft de Ottomaanse, Perzische, Chinese, Indische, Indiaanse en de «Zwarte » vreemdeling. De Muntschouwburg is sterk beïnvloed door het Franse theater. Deze studie is gebaseerd op de visie van de vreemdeling voorgesteld in de Franse literatuur om de overdracht van deze debatten in Brussel te observeren, door middel van theater. De studie analyseert vooroordelen over buitenlanders in de theaterstukken, en de gelijkenissen en de verschillen met de Franse filosofische debatten. Het Ottomaanse Rijk en Perzië zijn voorbeelden tegen de Europese manier van leven, een model meestal niet te imiteren. Behalve voor de islamitische religie, is de vergelijking tussen de Ottomaanse en de Europese zeden in het voordeel van de laatste. China, India, Amerika en de «Zwarten » zijn op hun beurt geplaatst op een ontwikkelingsschaal gaande van de natuur naar de beschaving. Het doel is de voordelen van de Europese plaats te tonen, tussen de «overbeschaving” van China en de «barbaarsheid » van de Indiërs, de Indianen en de «Zwarten » . In het algemeen zien we dat de verschillende vreemdelingen, voorgesteld in de Muntschouwburg zich integreren in de Franse debatten en filosofische vragen (despotisme, de voordelen of nadelen van de beschaving en de natuur, of verschillende religies) en dat vreemdelingen in werkelijkheid gebruikt zijn om de Europeaan in twijfel te trekken. We kunnen echter enkele verschillen merken met de Franse filosofische literatuur. Het eerste verschil is het komisch aspect dat vaak toegewezen wordt aan de vreemde. Ten tweede, de voorstelling van de buitenlanders in de Muntschouwburg is over het algemeen zeer positief. Tenslotte geeft de levendigheid van de debatten in de Franse filosofie niet noodzakelijk hun kracht weer in het theater.

Objective.Foot osteoarthritis (OA) is very common but underinvestigated musculoskeletal condition and there is little consensus as to common magnetic resonance imaging (MRI) features. The aim of this study was to develop a preliminary foot OA MRI score (FOAMRIS) and evaluate its reliability.Methods.This preliminary semiquantitative score included the hindfoot, midfoot, and metatarsophalangeal joints. Joints were scored for joint space narrowing (JSN; 0–3), osteophytes (0–3), joint effusion/synovitis, and bone cysts (present/absent). Erosions and bone marrow lesions (BML) were scored (0–3) and BML were evaluated adjacent to entheses and at sub-tendon sites (present/absent). Additionally, tenosynovitis (0–3) and midfoot ligament pathology (present/absent) were scored. Reliability was evaluated in 15 people with foot pain and MRI-detected OA using 3.0T MRI multi-sequence protocols, and assessed using ICC as an overall score and per anatomical site.Results.Intrareader agreement (ICC) was generally good to excellent across the foot in joint features (JSN 0.90, osteophytes 0.90, effusion/synovitis 0.46, cysts 0.87), bone features (BML 0.83, erosion 0.66, BML entheses 0.66, BML sub-tendon 0.60) and soft tissue features (tenosynovitis 0.83, ligaments 0.77). Interreader agreement was lower for joint features (JSN 0.43, osteophytes 0.27, effusion/synovitis 0.02, cysts 0.48), bone features (BML 0.68, erosion 0.00, BML entheses 0.34, BML sub-tendon 0.13), and soft tissue features (tenosynovitis 0.35, ligaments 0.33).Conclusion.This preliminary FOAMRIS demonstrated good intrareader reliability and fair interreader reliability when assessing the total feature scores. Further development is required in cohorts with a range of pathologies and to assess the psychometric measurement properties.
The implications of change in South African society for the health professions
Authors: Boshoff Hentie 
Published: June 2017

To address this problem, one has to look at (i) societal changes and future developments, (ii) changes in health care as such and (iii) the linkage between these two. In this respect we must realize that we are living in an era where economic, technological, demographic, social and political changes are accelerating. The interface between these changes results in the age of discontinuities as far as individual trends are concerned. To work therefore with projected futures amounts to brain gymnastics. A more realistic approach is to define the key drivers or trends and structures shaping the future of society and health care, and from this deduct the possible implications for health professions. Societal key drivers affecting change The process of societal change evolves around economic, technological, demographic, political and societal change.
Is it lawful to offer HIV self-testing to children in South Africa?
Authors: Strode Ann Elaine , Van Rooyen H , Makusha T 
Published: June 2017

Health-facility-based HIV counselling and testing does not capture all children and adolescents who are at risk of HIV infection. Self-testing involves conducting an HIV test at home or in any other convenient space without the involvement of a third party. It is increasingly being argued that it should be incorporated into national HIV-prevention programmes as one of a range of HIV counselling and testing approaches. Although this model of HIV testing is being seen as a new way of reaching under-tested populations, no studies have been conducted on offering it to children. HIV self-tests are now available in South Africa and are sold without the purchaser having to be a certain age. Nevertheless, all HIV testing in children must comply with the norms set out in the Children’s Act (2005). Here we explore whether offering self-testing to children would be lawful, by outlining the four legal norms that must be met and applying them to self-HIV testing. We conclude that, although children above the age of 12 years could consent to such a test, there would be two potential obstacles. Firstly, it would have to be shown that using the test is in their best interests. This may be difficult given the potential negative consequences that could flow from testing without support and the availability of other testing services. Secondly, there would need to be a way for children to access pre- and post-test counselling or they would have to be advised that they will have expressly to waive this right. The tests are more likely to be lawful for a small sub-set of older children if: (i) it assists them with HIV-prevention strategies; (ii) they will be able to access treatment, care and support, even though they have tested outside of a health facility; and (iii) psychosocial support services are made available to them via the internet or cell phones.
Closing the gaps: Steps towards elimination of mother-to-child transmission of HIV
Authors: Ibeto Mary , Giddy Janet , Cox Vivian 
Published: June 2017

Background. With significant reductions in the rate of HIV mother-to-child transmission (MTCT) in South Africa, each case of failed prevention of MTCT (PMTCT) should be investigated. Objective. To establish the cause(s) of MTCT at Khayelitsha’s Community Health Centre (CHC) in order to identify obstacles to MTCT elimination.Methods. Routinely collected data were reviewed for all HIV-infected infants identified at Khayelitsha Site B CHC from January 2012 to April 2013.Results. A total of 926/1 158 (80%) of exposed infants had polymerase chain reaction (PCR) results, with 15/926 (1.6%) PCR-positive. Median (interquartile range (IQR)) values for the maternal indicators were as follows: maternal age, 27 (23 - 31) years; parity, 2 (1 - 3); gestational age at antenatal presentation, 21.5 (17.5 - 30.5) weeks; CD4+, 377(219 - 446) cells/µl. Of the 15 PCR-positive infants, five received ART, five received AZT and five received no prophylaxis. Viral loads were not monitored for any of the women receiving antenatal ART. Nine of the 15 (60%) delivered in hospital, with 6/9 requiring caesarean section. The median (IQR) infant birth weight was 3.0 (2.6 - 3.5) kg. All received prophylactic nevirapine post exposure. Two of the 15 were clinically unwell at birth, and 14 (86.7%) were breastfed, with 10 (66.7%) recorded as exclusively breastfed. Median (IQR) time between delivery and PCR results was 6.6 (6.1 - 7.3) weeks. Discussion. PMTCT programmes must consider each PCR-positive infant as a sentinel event that can provide valuable insight into correcting ongoing clinical and programmatic reasons for HIV transmission. The main risk factors for MTCT identified in this study were late presentation for antenatal care, inadequate antenatal PMTCT prophylaxis and a lack of viral load monitoring.
