Friction-Load Redistribution for Extended-Reach- and Horizontal-Well Completions
Authors: Carpenter Chris 
Published: January 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper IADC/SPE 178905, “Friction-Load Redistribution for Robust and Cost-Efficient Design of Extended-Reach- and Horizontal-Well Completions,” by A.R. McSpadden, SPE, and R. Trevisan, SPE, Altus Well Experts, prepared for the 2016 IADC/SPE Drilling Conference and Exhibition, Fort Worth, Texas, USA, 1–3 March.
In horizontal and extended-reach wells in which long completions are run into highly deviated or lateral zones, large compression loads arise because of running friction. These loads remain locked in the string when the packer or cement sets. Dissipation of friction caused by string vibrations and movements redistributes these friction loads between the wellhead and the packer or the top of the cement. A numerical approach is presented to calculate the redistributed friction load so that an accurate initial tubing load is implemented in the tubular-stress analysis.
Introduction
The long lateral wells in modern shale developments provide new motivation to better understand and model the effect of friction in casing and tubing design. The multiple-barrier approach and modern design techniques compare favorably with previous generations of well construction. Even so, the root-cause failure analysis of individual subsurface components such as tubing, connections, or packers is difficult. The multizone- fracture-stimulation techniques common to shale developments combine the multiple challenges of long lateral zones with associated friction-induced compression loads and cyclic thermal loading from successive stimulation, flowback, and production.
An important motivation for understanding the effect of redistribution of locked-in friction loads is the increasing application of onetrip multistage completions and intelligent-well-system completions in unconventional- reservoir field developments. In extended-reach wells, as the long laterals grow longer and more-expensive equipment is run out farther into the reservoir-contact area, design requirements will become increasingly challenging.
It can be argued that these considerations are not as important for cemented completions or where the production casing is the effective operational conduit. However, even for production-casing fracture stimulations or even production, loads below the top of the cement cannot necessarily be disregarded. Also, the planned top-of-cement depth may not be realized. Hence, much more of the casing may be uncemented than in the original plan.
Solving Produced-Water Challenges With a Novel Guar-Based System
Authors: Wilson Adam 
Published: January 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 177678, “Solving Field Produced-Water Challenges With a Novel Guar- Based System: A Comprehensive Review of Actual Field Examples and Cost-Savings Analysis,” by Branden Ruyle, SPE, and Francisco E. Fragachan, SPE, Weatherford, prepared for the 2015 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 9–12 November. The paper has not been peer reviewed.
This paper summarizes the benefits of using a bipolymer crosslinking system in environments where water quality cannot be guaranteed. In addition to the cost advantages of using a crosslinking system that uses a conventional gelling agent, this paper also demonstrates the yielded cost savings per well that are achievable when reusing 100% produced or flowback water for hydraulic fracturing. The new fluid system consists of a specially formulated biopolymer crosslinking system that is not affected by the inconsistent quality of produced/ flowback water typically associated with fracturing applications.
Introduction
Water management is an environmental and logistical challenge to many operators across the United States. With the typical unconventional horizontal well requiring, on average, more than 8 million gal of water in a standard stimulation design, the need for an alternative to fresh water is a growing concern. A common approach to help mitigate freshwater use is on-site or centralized filtration to return produced or flowback water to a usable base fluid and even to fresh water in some cases, depending on the chemistry used and application. Filtration methods are considered a standard approach that lowers completion costs in terms of disposal reduction and freshwater conservation. However, many fracturing chemistries require increased filtration methods that create not only increased solid waste but also an associated cost burden because the cost of recycled produced water is more than double that of fresh water.

Authors: Mahmoud Ahmed Mohammed , Nasrat Loai S. , Ibrahim Abd Allah Ahmed 
Published: January 2017

Poly vinyl chloride (PVC) is widely used in high and medium voltage cables insulation due to its low dielectric losses and its ability to improve cables properties in high temperatures. This paper aims to improve PVC electrical properties (dielectric strength) for high voltage and medium voltage cables in respect of mechanical characteristics by adding ethylene propylene diene monomer (EPDM). Blends of PVC with EPDM were prepared with 0%, 20%, 35%, 50%, 65%, 80%, and 100% by weight percentages concentration. The dielectric strength of the blends was tested in several conditions such as dry, wet and salty wet condition. Tensile strength test was applied to check mechanical properties of the blends. Results were analyzed using least square method in a way to determine the optimum percentage of mixing PVC/EPDM blend, which gives the best of electrical and mechanical properties under different conditions.

Published: January 2017

Abstract
OBJECTIVE To determine whether canine protein C (CnPC) had antichemotactic effects on canine neutrophils, whether endothelial protein C receptor (EPCR) was expressed on canine neutrophils, and the role of EPCR in neutrophil chemotaxis.
SAMPLE Neutrophils isolated from blood samples from healthy dogs (n = 6) and sick dogs with (2) or without (3) an inflammatory leukogram.
PROCEDURES Neutrophils were analyzed by reverse transcriptase PCR assay and flow cytometry for detection of EPCR mRNA and protein expression, respectively. Neutrophils were incubated with CnPC zymogen or canine activated protein C (CnAPC), with or without RCR-379 (an anti–human EPCR antibody). Neutrophils were then allowed to migrate through a filter membrane toward a chemokine. Untreated neutrophils served as positive control samples. Migration was quantified by fluorescence measurement, and chemotaxis index (Chx) values (fluorescence of test sample/fluorescence of positive control sample) were computed.
RESULTS The cDNA for EPCR was amplified, and EPCR expression was detected on neutrophil surfaces. Obtained Chx values were significantly higher in cells treated with RCR-379 than in cells treated with CnPC or CnAPC alone. The Chx values for neutrophils treated with RCR-379 were not significantly different from 1, whereas those for neutrophils treated without RCR-379 were significantly less than 1. The effects of RCR-379 on neutrophil migration were independent of concentration or activation status of protein C.
CONCLUSIONS AND CLINICAL RELEVANCE Canine neutrophils expressed EPCR, and inhibition of neutrophil chemotaxis by CnPC and CnAPC depended on EPCR. Interventions with EPCR signaling may have therapeutic application in dogs.

Published: January 2017

Background:
Patient care problems arise when health care consumers and professionals find health information on the Internet because that information is often inaccurate. To mitigate this problem, nurses can develop Web literacy and share that skill with health care consumers. This study evaluated a Web-literacy intervention for undergraduate nursing students to find reliable Web-based health information.

Method:
A pre- and postsurvey queried undergraduate nursing students in an informatics course; the intervention comprised lecture, in-class practice, and assignments about health Web site evaluation tools. Data were analyzed using Wilcoxon and ANOVA signed-rank tests.

Results:

Pre-intervention, 75.9% of participants reported using Web sites to obtain health information. Postintervention, 87.9% displayed confidence in using an evaluation tool. Both the ability to critique health Web sites (
p
= .005) and confidence in finding reliable Internet-based health information (
p
= .058) increased.

Conclusion:

Web-literacy education guides nursing students to find, evaluate, and use reliable Web sites, which improves their ability to deliver safer patient care. [

SMS can be utilized as a new opportunity that can be applied to improve current educational practices and processes in a variety of fields, including distance education. This study is an in-depth qualitative inquiry into distance education students’ perception and experience in mobile learning via SMS. A set of interview questions was used as the survey method to gather primary data from five students enrolling in the School of Distance Education, Universiti Sains Malaysia. The findings revealed that SMS learning generally was perceived positively by the respondents. They agreed that SMS learning is convenient, useful as reminder and relevant to their studies. Apart from few issues raised, respondents agreed that their SMS learning experiences were great, helpful and they generally satisfied with the system. As implications, the study shed lights on the potential of SMS learning as an effective and innovative paradigm in pedagogy particularly in distance education environment.
CD31, a Valuable Marker to Identify Early and Late Stages of T Cell Differentiation in the Human Thymus

Abstract
Although CD31 expression on human thymocytes has been reported, a detailed analysis of CD31 expression at various stages of T cell development in the human thymus is missing. In this study, we provide a global picture of the evolution of CD31 expression from the CD34+ hematopoietic precursor to the CD45RA+ mature CD4+ and CD8+ single-positive (SP) T cells. Using nine-color flow cytometry, we show that CD31 is highly expressed on CD34+ progenitors and stays high until the early double-positive stage (CD3−CD4+CD8α+β−). After β-selection, CD31 expression levels become low to undetectable. CD31 expression then increases and peaks on CD3highCD4+CD8+ double-positive thymocytes. However, following positive selection, CD31 expression differs dramatically between CD4+ and CD8+ lineages: homogeneously high on CD8 SP but lower or negative on CD4 SP cells, including a subset of CD45RA+CD31− mature CD4+ thymocytes. CD31 expression on TCRγδ thymocytes is very similar to that of CD4 SP cells. Remarkably, there is a substantial subset of semimature (CD45RA−) CD4 SP thymocytes that lack CD31 expression. Moreover, FOXP3+ and ICOS+ cells are overrepresented in this CD31− subpopulation. Despite this CD31−CD45RA− subpopulation, most egress-capable mature CD45RA+ CD4 SP thymocytes express CD31. The variations in CD31 expression appear to coincide with three major selection processes occurring during thymopoiesis: β-selection, positive selection, and negative selection. Considering the ability of CD31 to modulate the TCR’s activation threshold via the recruitment of tyrosine phosphatases, our results suggest a significant role for CD31 during T cell development.

Abstract
With enhanced concerns of terrorist attacks, dual exposure to radiation and thermal combined injury (RCI) has become a real threat with devastating immunosuppression. NLRP12, a member of the NOD-like receptor family, is expressed in myeloid and bone marrow cells and was implicated as a checkpoint regulator of inflammatory cytokines, as well as an inflammasome activator. We show that NLRP12 has a profound impact on hematopoietic recovery during RCI by serving as a checkpoint of TNF signaling and preventing hematopoietic apoptosis. Using a mouse model of RCI, increased NLRP12 expression was detected in target tissues. Nlrp12−/− mice exhibited significantly greater mortality, an inability to fight bacterial infection, heightened levels of proinflammatory cytokines, overt granulocyte/monocyte progenitor cell apoptosis, and failure to reconstitute peripheral myeloid populations. Anti-TNF Ab administration improved peripheral immune recovery. These data suggest that NLRP12 is essential for survival after RCI by regulating myelopoiesis and immune reconstitution.
Implicitly Restarted Refined Partially Orthogonal Projection Method with Deflation
Authors: Wei Wei , Dai Hua 
Published: January 2017

AbstractIn this paper we consider the computation of some eigenpairs with smallest eigenvalues in modulus of large-scale polynomial eigenvalue problem. Recently, a partially orthogonal projection method and its refinement scheme were presented for solving the polynomial eigenvalue problem. The methods preserve the structures and properties of the original polynomial eigenvalue problem. Implicitly updating the starting vector and constructing better projection subspace, we develop an implicitly restarted version of the partially orthogonal projection method. Combining the implicit restarting strategy with the refinement scheme, we present an implicitly restarted refined partially orthogonal projection method. In order to avoid the situation that the converged eigenvalues converge repeatedly in the later iterations, we propose a novel explicit non-equivalence low-rank deflation technique. Finally some numerical experiments show that the implicitly restarted refined partially orthogonal projection method with the explicit non-equivalence low-rank deflation technique is efficient and robust.

Published: February 2017

Abstract
OBJECTIVE. This systematic review investigated the role of home modification interventions to improve participation outcomes for community-living adults and older adults.
METHOD. Thirty-six articles met the inclusion criteria. The majority of the studies investigated older adult populations and used occupational therapists as interventionists.
RESULTS. Strong evidence was found for home modification interventions to improve function for people with a variety of health conditions and for both single and multicomponent interventions that included home modifications to reduce the rate and risk of falls among older adults. Moderate evidence was found for improved caregiving for people with dementia.
CONCLUSION. Comprehensive, higher intensity interventions demonstrated greater efficacy to improve occupational performance. Emerging evidence was also found for the role of occupational therapy in providing effective home modification interventions. Implications for occupational therapy practice, education, and research are discussed.
Between Signsystems and Affects
Authors: Sjöholm Cecilia 
Published: January 2017

Gotthold Ephraim Lessing’s Laocoon (1766) saw that the signification of art cannot be dissociated from its media. A visual work of art and a literary work originates in different spatial and temporal conditions, Lessing argued, serving thereby to liberate art from the tradition of ut pictura poesis. Lessing’s impact has been discussed in the tradition of modernism through Babbitt, Eisenstein and Greenberg, and there been associated with the notion that the work of art is autonomous. In Lessing’s own text, however, there is no clear conception of a work of art “an sich”. Instead, the work of art is characterized in an indirect manner, through the sense perception of the reader or viewer. Lessing’s Laocoon can be rethought from the perspective of affect. In his text, the human body has a central place, and Lessing’s investigation into the signification of the Laocoon can be formulated as the question: How does the embodied mind respond to the image of a human body? Departing from this concern, Lessing’s text does not only look at the object of aesthetics; it constructs an aesthetic subject, in which the embodied conditioning of sense perception and the question of affect is central. Making the statue of Laocoon a primary example in his study, Lessing inserts himself in a long tradition of the study of affects where Laocoon represents the most pain that a human can bear, whether that pain is corporeal or emotional.
Cultural Encounters in Modern Productions of Greek Tragedy
Authors: Wilmer S.E. 
Published: January 2017

The exiled character in need of asylum is a recurrent theme in ancient Greek tragedy. In many of these plays, we see uprooted and homeless persons seeking sanctuary, and for the ancient Greeks, hospitality was an important issue. Many of these plays have been updated to comment on the current social and political conditions of refugees and often reflect on the notion of hospitality, something which both Emmanuel Levinas and Jacques Derrida considered to be fundamental to ethics.
Recently there has been a series of demonstrations and occupations of public spaces by asylum seekers that has gained considerable news coverage. In Austria a group of about sixty refugees (from the Afghanistan-Pakistan border area) occupied the famous Votiv church in the middle of Vienna in 2012 and went on hunger strike. In Germany a large group of asylum seekers marched from various parts of the country to Berlin where they occupied the square at the Brandenburg Gate before being allowed to establish a tent community in Kreuzberg. In Hamburg a group of 80 asylum seekers who came to Germany via Lampedusa found refuge in St Pauli church, and it was there that Nicholas Stemann presented a first reading of Elfriede Jelinkek’s play Die Schutzbefohlenen in September 2013. More recently right-wing groups have mounted weekly marches through Dresden to call for a halt to immigration, and these have been contested by simultaneous counter-demonstrations in favour of immigrants and refugees. In this paper I will consider several adaptations of Greek tragedy that highlight cultural encounters between the local population and those arriving from abroad who are looking for asylum. In particular I will examine Stemann’s production that has been running at the Thalia Theater in Hamburg since September 2014, and features asylum seekers from Lampedusa on stage who beg the audience for the right to remain in Germany.
