Chelating-Agent Enhanced Oil Recovery for Sandstone and Carbonate Reservoirs
Authors: Mahmoud M. A. , Abdelgawad K. Z. 
Published: April 2015

Summary
Recently low-salinity waterflooding was introduced as an effective enhanced-oil-recovery (EOR) method in sandstone and carbonate reservoirs. The recovery mechanisms that use low-salinity-water injection are still debatable. The suggested possible mechanisms are: wettability alteration, interfacial-tension (IFT) reduction, multi-ion exchange, and rock dissolution. In this paper, we introduce a new chemical EOR method for sandstone and carbonate reservoirs that will give better recovery than the low-salinity-water injection without treating or diluting seawater.
In this study, we introduce a new chemical EOR method that uses chelating agents such as ethylenediaminetetraacetic acid (EDTA), hydroxyethylethylenediaminetriacetic acid (HEDTA), and diethylenetriaminepentaacetic acid (DTPA) at high pH values. This is the first time for use of chelating agents as standalone EOR fluids. Coreflood experiments, interfacial and surface tensions, and zeta-potential measurements are performed with DTPA, EDTA, and HEDTA chelating agents. The chelating-agent concentrations used in the study were prepared by diluting the initial concentration of 40 wt% with seawater and injecting it into Berea-sandstone and Indiana-limestone cores of a 6-in. length and a 1.5-in. diameter saturated with crude oil. The coreflooding experiments were performed at 100°C and a 1,000-psi backpressure. Low-salinity-water and seawater injections caused damage to the reservoir because of the calcium sulfate scale deposition during the flooding process. The newly introduced EOR method did not cause calcium sulfate precipitation, and the core permeability was not affected. The core permeability was measured after the flooding process, and the final permeability was higher than the initial permeability in the case of chelating-agent injection. The coreflooding effluent was analyzed for cations with the inductively coupled plasma (ICP) spectroscopy to explain the dissolution-recovery mechanism. The effect of iron minerals on the rock-surface charge was investigated through the measurements of zeta potential for different rocks containing different iron minerals.
HEDTA and EDTA chelating agents at 5 wt% concentration prepared in seawater were able to recover more than 20% oil from the initial oil in place from sandstone and carbonate cores. ICP measurements supported the rock-dissolution mechanism because the calcium, magnesium, and iron concentrations in the effluent samples were more than those in the injected fluids. The IFT-reduction mechanism was confirmed by the low IFT values obtained in the case of chelating agents. The type and concentration of chelating agents affected the IFT value. Higher concentrations yielded lower IFT values because of the increase in carboxylic-group concentration. We found that the high-pH chelating agents increased the negative value of zeta potential, which will change the rock toward more water-wet.

Genetic modeling of feed intake

Published: April 2015

ABSTRACT
With the development of automatic self-feeders and electronic identification, automated, repeated measurements of individual feed intake (FI) and BW are becoming available in more species. Consequently, genetic models for longitudinal data need to be applied to study FI or related traits. To handle this type of data, several flexible mixed-model approaches exist such as character process (CPr), structured antedependence (SAD), or random regression (RR) models. The objective of this study was to compare how these different approaches estimate both the covariance structure between successive measurements of FI and genetic parameters and their ability to predict future performances in 3 species (rabbits, ducks, and pigs). Results were consistent between species. It was found that the SAD and CPr models fit the data better than the RR models. Estimations of genetic and phenotypic correlation matrices were quite consistent between SAD and CPr models, whereas correlations estimated with the RR model were not. Structured antedependence and CPr models provided, as expected and in accordance with previous studies, a decrease of the correlations with the time interval between measurements. The changes in heritability with time showed the same trend for the SAD and RR models but not for the CPr model. Our results show that, in comparison with the CPr model, the SAD and RR models have the advantage of providing stable predictions of future phenotypes 1 wk forward whatever the number of observations used to estimate the parameters. Therefore, to study repeated measurements of FI, the SAD approach seems to be very appropriate in terms of genetic selection and real-time managements of animals.

Abstract
An analysis of the parameters of multi-stage controlled strip cooling during the process of rolling of 5.5 mm-diameter C70D high-carbon steel wire rod has been made in this publication. Investigations included also the analysis of the flow rate of the cooling medium and its pressure in the devices for accelerated and controlled cooling of the strip directly in the rolling line, as well as in the STELMOR line. The investigations carried out within the study have determined the cooling capacity of the accelerated strip cooling devices for specific (preset) cooling conditions. The scope of the investigations also encompassed the analysis of the effect of the employed cooling conditions on the temperature distribution and on the properties and microstructure of the steel studied. Moreover, physical modeling of the currently applicable technology of rolling the investigated steel grade was also performed.

Published: April 2015

AbstractAlkaline treatment of the black rice husk ash (BRHA) was done by immersing BRHA in 8 % sodium hydroxide, NaOH, solution for 24 hours and then the treated BRHA (TBRHA) was neutralized, washed and dried in an oven. The TBRHA was subsequently compounded with the polypropylene (PP) by using single screw extruder machine, and followed by compression molding at 185 °C. The physical properties results showed that the density and the water absorption behavior of the TBRHA filled PP biocomposite (TBRHA-PP) are higher and lower, respectively, when compared with the untreated BRHA filled PP biocomposites (UBRHA-PP). The melt flow index value of the TBRHA-PP biocomposite is also higher in comparison with the UBRHA-PP biocomposites. The mechanical properties results exhibited that the tensile stress, tensile strain, flexural modulus and impact strength of the TBRHA-PP biocomposite are higher than of the UBRHA-PP biocomposites. However, the tensile modulus of the TBRHA-PP biocomposite is slightly lower as compared with the UBRHA-PP biocomposites. Therefore, it could be concluded that the alkaline treatment of the BRHA has improved some of the physico-mechanical properties of the BRHA filled PP biocomposites.

Authors: Singh Lakhwinder Pal , Singh Jagtar 
Published: April 2015

Abstract
The cryogenic treatment process is carried out at sub-zero temperatures down to −184 °C to modify the microstructure and properties of the material. This process is an extension of heat treatment which further improves the properties of the material. This publication focuses on the effect of cryogenic treatment on high speed steel (HSS) T-42 tool material. In this research, cryogenic treatment at −184 °C is conducted and the properties of the material compared with them of untreated material. As the temperature is decreased, microstructure of material is refined and a higher number of carbide precipitates appeared on the surface after the treatment. The microstructural changes result in improvement of properties of HSS, (T-42) tool material. Pin-on-disc wear test is conducted on untreated (UT) HSS and cryogenic treated (CT) HSS specimens. It is observed that the average wear rate of UT-HSS and CT-HSS samples is 6.8 × 10−8 mm3/Nm and 4.1 × 10−8 mm3/Nm, respectively. The average wear rate has been improved by 39.71 % for CT-HSS compared to UT-HSS tool material.
Application of the response surface methodology in the ball burnishing process for the prediction and analysis of surface hardness of the aluminum alloy AA 7075
Authors: Kahraman Funda 
Published: April 2015

Abstract
In this study, AA 7075 aluminum alloy has been burnished using different burnishing parameters such as burnishing force, number of passes, feed rate and burnishing speed with a ball burnishing apparatus. Burnishing parameters, which affect the surface hardness, were examined using response surface methodology with rotatable central composite design and analysis of variance. Using the experimental results, a regression model has been developed to predict surface hardness. The statistical analysis showed that, burnishing force and number of passes have the most significant effect on surface hardness. These results, which were obtained from the regression model, are highly consistent with the experiments. The absolute average error between the experimental and predicted values for surface hardness was calculated as 2.79 %. The results of our study show that response surface methodology is a suitable technique that can be efficiently used to predict surface hardness in ball burnishing process.

Published: April 2015

Abstract
AISI type 316L stainless steel was used as a heat exchanger tube material in an inter-cooler column. After less than a year of operation, severe corrosion failures occurred and a transverse opening leakage was observed on one of the heat exchanger tubes. The failed tube was carefully analyzed using various metallurgical laboratory equipments. The root cause of the tube leakage was believed due to the presence of horizontal micro and macro pores as a hydrogen gas entrapment during casting of the parent ingot. The overlapped and gaping pores formed notch on the shell side of the tube surface, and it increasingly evident when the use of a high-energy water-jet and metal brush as cleaning procedure results in an establishment of pitting type local-action corrosion cells penetrated the tube wall. As a result, corrosive fluid in the tube side dissolved into the cooling water, accelerating the corrosion process.
Pooled data analysis on anterior versus posterior approach for rheumatoid arthritis at the craniovertebral junction
Authors: Chieng Lee Onn , Madhavan Karthik , Vanni Steven 
Published: April 2015

OBJECT
Rheumatoid arthritis (RA) is one of the most debilitating autoimmune diseases affecting the craniovertebral junction (CVJ). Patients predominantly present with myelopathic symptoms and intractable neck pain. The surgical approach traditionally has been either a combined anterior and posterior approach or a posterior-only approach. In this article, the authors review pooled data from the literature and discuss the benefits of the two types of approaches.

METHODS
A search of the PubMed database was conducted using key words that describe spine deformities in RA and specific spinal interventions. The authors evaluated the neurological outcomes based on the Ranawat scale in both the groups through chi-square analysis. Multiple logistic regression was carried out to further examine for potential confounders. Any adverse sequalae resulting from either approach were also documented. Because all the procedures performed via a transoral approach in the analyzed articles also involved posterior fixation, for convenience of comparison, the combined procedures are referred to as “anterior approach” or “anterior-posterior” in the present study.

RESULTS
The search yielded 233 articles, of which 11 described anterior approaches and 14 evaluated posterior approaches. The statistical analysis showed that patients treated with a posterior approach fared better than those treated with an anterior (combined) approach. It was noted that those patients in whom the cervical subluxations were reducible on traction predominantly underwent posterior approaches.

CONCLUSIONS
CVJ instability is a serious complication of RA that requires surgical intervention. Although the anterior-posterior combined approach can provide direct decompression, it is associated with morbidity, and the analysis showed no statistically significant benefit to patients. In contrast, the posterior approach has been shown to provide statistically significant superiority with respect to stabilization and subsequent pannus reduction. Surgical approaches are undertaken based on the reducibility of subluxations with traction and the vector of compressive force. However, the choice of surgical approach should be based on the individual patient's pathology.
Lumière des nations et gloire d’Israël. Le programme de Nostra aetate 4 pour le renouvellement de la christologie
Authors: Andrevon Martine-Thérèse 
Published: April 2015

La promulgation de Nostra aetate 4 a profondément modifié la relation de l’Église au peuple juif. Elle met aussi en lumière de nouveaux défis théologiques. Parmi eux, la christologie apparaît comme une discipline majeure pour une théologie chrétienne du judaïsme. Mais quelle incidence la judéité retrouvée de Jésus a-t-elle pour le chrétien du xxi e siècle ? L’article commence par analyser les traces de christologie que l’on peut trouver dans les principaux textes récents du Magistère qui traitent de la question des juifs et du judaïsme. Puis l’A. propose quelques pistes pour élaborer une christologie, non pas de la séparation avec Israël, mais où le Christ constitue le nœud entre juifs et chrétiens, à la fois leur connexion et leurs désaccords.
« Ils seront ses peuples... » (Ap 21,3). Redécouvrir la théologie du peuple de Dieu
Authors: Guggenheim Antoine 
Published: April 2015

On a d’abord reçu l’enseignement du concile Vatican ii sur l’Église comme « peuple de Dieu » comme une réponse théologique au contexte de la sécularisation. Sans renier l’apport positif de ces interprétations, on doit relire aujourd’hui les textes du Concile dans le contexte de la globalisation. La transformation des relations avec le judaïsme et l’intensification du dialogue interreligieux, que le Concile a initiées et que demande la rencontre des peuples, renouvelle la compréhension du syntagme « peuple de Dieu » et précise sa pertinence pour exprimer la responsabilité de l’Église et des chrétiens dans le moment présent de l’histoire.
Towards an Immanent Critique of Forms of Life
Authors: Jaeggi Rahel 
Published: April 2015

Une critique des formes de vie est-elle possible ? Peut-on dire que des formes de vie sont bonnes, réussies ou même rationnelles ? Tandis que la philosophie a abandonné la question socratique de la vie bonne, la politique des démocraties libérales constitutionnelles se présente comme une manière d’organiser la coexistence en restant neutre quand aux différentes formes de vie. La façon dont nous devons vivre notre vie est reléguée à la sphère privée, comme une préférence singulière qui ne peut pas être questionnée. Dans cet article, l’auteur avance la possibilité d’une critique sociale immanente des formes de vie, dépassant ainsi les distinctions contraignantes entre l’éthique et la morale, la vie bonne et les principes moraux, le bien et le juste. Cela suppose d’expliquer d’abord ce que sont les formes de vie, comment elles fonctionnent, et quelle en est l’ontologie qui les rend réactives à la critique. Pour qu’une critique ne soit pas arbitraire, l’auteur montre ensuite que les raisons et les standards de la critique se trouvent dans la structure même des formes de vie, une fois qu’on les comprend comme des processus historiquement situés de résolution de problèmes. Les formes de vie sont donc en interaction avec leur critique ; celle-ci peut alors être immanente et émancipatrice.
Les sciences sociales au service de la « modernisation » dans la formation de l’encadrement à EDF
Authors: Martin Emmanuel 
Published: April 2015

L’encadrement joue un rôle crucial dans la modernisation des entreprises publiques : il est chargé de « conduire le changement ». À cet effet, des dispositifs de formation sont mis en place pour convertir les encadrants à leur rôle de manager, tout au long du processus de modernisation de l’entreprise EDF. Loin d’occuper une place marginale, les sciences sociales (psychosociologie et sociologie, en particulier), implantées de longue date dans cette entreprise, interviennent dans ces dispositifs comme des auxiliaires utiles. Il s’agit de faire accepter aux (futurs) encadrants les contradictions fondatrices associées à leur fonction et à leur position dans la hiérarchie. À ce problème, les sciences sociales apportent une contribution décisive, notamment par le biais de dispositifs qui entraînent les (futurs) encadrants à exercer leur autorité, et cherchent à transformer leur subjectivité. Néanmoins, le recours aux sciences sociales est de moins en moins fréquent, en raison de son coût relatif face à des méthodes plus « pragmatiques ».

À partir de données ethnographiques recueillies dans des commissariats de sécurité publique en région parisienne et à Berlin, cet article propose de comparer les formes de racialisation des discours policiers et des interactions entre police et population. La recherche montre tout d’abord que la manière dont les policiers problématisent l’altérité présente des similitudes entre Berlin et la région parisienne ; ensuite, que si les populations minoritaires font l’objet d’un ciblage policier dans les deux contextes, la nature de ce ciblage diffère entre les cas français et allemand. Les stratégies de prévention mises en place à Berlin conduisent notamment à réduire la fréquence des pratiques policières les plus coercitives. La recherche invite à minorer les explications individuelles au profit d’une approche plus systémique des discriminations policières.
Chronic innominate artery occlusion with hyperacute intracranial thromboembolism: Revascularization with simultaneous local thromboaspiration and mechanical thrombectomy
Authors: Gordhan Ajeet , Vanle Jesse 
Published: April 2015

Chronic innominate artery occlusion with acute right internal carotid terminus thromboembolism and successful revascularization using simultaneous local thromboaspiration and mechanical thrombectomy has not been previously described. A 51-year-old male presented with transient left hemiparesis. A CT angiogram of the head and neck demonstrated chronic occlusion of the right innominate artery with no intracranial thromboembolism. More profound symptoms recurred twelve hours after admission. A diagnostic catheter-based angiogram confirmed occlusion of the innominate artery and identified hyper-acute right carotid terminus thromboembolism. Angioplasty of the innominate artery was followed by simultaneous mechanical and aspiration thrombectomy of the right internal carotid artery terminus. Combination local thromboaspiration and mechanical thrombectomy was shown in this case to be effective in achieving a favorable clinical outcome.
Phosphatase PTPN4 Preferentially Inhibits TRIF-Dependent TLR4 Pathway by Dephosphorylating TRAM

Abstract
TLR4 recruits TRIF-related adaptor molecule (TRAM, also known as TICAM2) as a sorting adaptor to facilitate the interaction between TLR4 and TRIF and then initiate TRIF-dependent IRF3 activation. However, the mechanisms by which TRAM links downstream molecules are not fully elucidated. In this study, we show that TRAM undergoes tyrosine phosphorylation upon TLR4 activation and that is required for TLR4-induced IRF3 activation. Protein tyrosine phosphatase nonreceptor type 4 (PTPN4), a protein tyrosine phosphatase, inhibits tyrosine phosphorylation and subsequent cytoplasm translocation of TRAM, resulting in the disturbance of TRAM–TRIF interaction. Consequently, PTPN4 specifically inhibits TRIF-dependent IRF3 activation and IFN-β production in TLR4 pathway. Therefore, our results provide new insight into the TLR4 pathway and identify PTPN4 as a specific inhibitor of TRIF-dependent TLR4 pathway. Targeting PTPN4 would be beneficial for the development of new strategy to control TLR4-associated diseases without unwanted side effects.
