Last-Engaged Thread-Height Reduction of Pin Increases Fatigue Life of Drill Collar
Authors: Tsukano Y. , Nishi S. , Nishida S. , Ueno M. 
Published: October 2015

ABSTRACT
Most drill collar fatigue failure occurs in the last-engaged thread (LET) of the pin. This type of failure is because of the concentration of thread loading in this area. As a method to decrease the load concentration, the LET thread height reduction is presented in this paper. Firstly, the effectiveness of the LET height reduction was verified using finite element analysis. Secondly, the analytical results were supported using full-size fatigue tests. Finally, the practicability of the redesigned connection was confirmed through torsional test, make-and- break test and full-size tensile test.
Capillary Pressure in Fractured Porous Media
Authors: Firoozabadi A. , Hauge J. 
Published: October 2015

ABSTRACT
A phenomenological model for fracture capillary pressure has been proposed. In this model, the fracture faces are assumed to be covered with cones, where every cone contacts the tip of another opposing cone. Cones in contact at the tip represent both roughness and aperture of a fracture surface. The solution to the Laplace-Young equation of capillarity is used to relate the fracture capillary pressure to the saturation. The computed Pc-saturation results show a porous-media behavior for the fracture capillary pressure.
Experiments with a stack of small matrix blocks in a centrifuge were also conducted. The measured production rates, and the matrix block saturations at the termination of the experiments confirm the validity of the porous-media model for the fracture capillary pressure. In some of the experiments, capillary pressure as high as 40 psi [0.275 MPa] could be imposed on the fractures of the stack of blocks that were used in the centrifuge experiments.

ABSTRACT
History matches of high and low quality five-spot steamfloods have been developed for the Kern River Field. A uniform set of guidelines was then developed for predictive purposes. Oil and water production rates as well as cumulatives were matched. Satisfactory predictions of steam breakthrough times, oil saturation profiles, and temperature profiles were also achieved.
An Experimental Study of Casing Performance Under Thermal Recovery Conditions

Published: October 2015

ABSTRACT
A study was conducted to investigate the behavior of casing pipe body and connection under simulated thermal recovery conditions. Performed in a new computer-controlled thermal well simulator, the study examined the thermal stress behavior and the leak resistance of the pipe and connection at temperatures up to 354°C (670°F) under severe loading conditions similar to those encountered in thermal wells. Also studied was the biaxial collapse resistance of the casing under the large axial tension that would exist after the cooling period in a steam stimulation process.
Results indicate that in a steam injection process in which the casing is maintained at its maximum temperature for a period of time, stress relaxation can occur in a constrained production casing, resulting in the development of excessive tensile stress during the cooling of the casing. Premium connections with metal-to-metal seal maintained gas leak resistance at temperatures up to 354°C (670°F) whereas the connections without the metal seal did not. The biaxial collapse resistance of casing under large axial tension was dependent on the stress-strain characteristics of the material. Hot-rolled K55 casing with work hardening characteristics showed a higher biaxial collapse resistance than expected from the von Mises yield criterion.
Based on the results of this study, it is concluded that heavy weight K55 casing with premium connection is a good candidate for thermal well completions.
A Laboratory Investigation of Foam Flow in Sandstone at Elevated Pressure

Published: October 2015

ABSTRACT
Use of foam as a mobility-control fluid in underground applications such as enhanced oil recovery and natural gas or air storage in aquifers requires quantitative information on its flow behavior in porous media at relevant conditions. Little information is currently available in consolidated sands and at pressures characteristic of reservoir depths. We study the flow of foam through a 1.3 μm2 Boise sandstone core at ambient temperature and at back pressures up to 5.2 MPa (750 psia). Total superficial velocities range from 1 to 45 m/day, and inlet foam qualities range from 0.70 to 0.996. Sequential pressure taps and gamma-ray attenuation are used to measure local flow resistances and liquid saturations during transient displacement and in the steady state.
We find that foam in the unsteady state is rheopectic; in the steady state it is shear thinning with respect to increasing gas flow but Newtonian with respect to increasing liquid flow. That is, steady pressure gradients for foam are sensibly independent of gas velocity but increase nearly linearly with increasing liquid velocity. No hysteresis in foam flow resistance is noted. Also at steady state, the pressure profile is linear and the liquid saturation is uniform and constant between 30 and 35%, a value that is about 10 saturation units above connate. The steady-state liquid saturation is practically independent of flow rate and inlet foam quality. Hence, foam flow resistance is not a unique function of liquid saturation.
Steady-state flow behavior of foam is rationalized in terms of changes in bubble texture. We also suggest a unique way of plotting foam flow behavior such that all our data collapse to a single constant which is characteristic only of the porous medium and the stabilizing surfactant package. If proven general, this correlation should be very useful for estimating foam mobilities as input to numerical simulations of possible field applications.

Published: October 2015

<p>El objetivo de esta presentación es exponer los resultados de tres investigaciones cualitativas sobre el ejercicio de los derechos y deberes en las PC, realizadas en Buenos Aires, Argentina. Ellas incluyeron entrevistas a madres de niños con Necesidades Básicas Insatisfechas concretadas entre los años 2009 y 2013. Su análisis, reveló que en este conjunto de hogares se llevaban a cabo tres tipos de PC: imposición, guía y libre albedrío, siendo esta última la más utilizada. Como parte de esta práctica, los niños administraban sus horarios de sueño, vigilia y tiempo libre, sin intervención de sus padres. Se observó, por ejemplo, que los niños mayores de 10 años decidían sobre aspectos relativos a su escolaridad, ausentándose de manera progresiva a la escuela, hasta el abandono. Estas prácticas eran respetadas por sus padres. Por defecto, no se ejercitó la postergación del placer (tolerancia a la frustración), debido a que se dejaba hacer a los niños a voluntad. También se advirtió una tendencia al embarazo adolescente y a la formación de parejas de niños entre 14 a 16 años, con consentimiento de sus padres. En este sentido, aun cuando los niños residían en un hogar en contacto con sus padres, con una oferta de alimentos y escolar, el ejercicio indiscriminado del libre albedrío de los niños ponía en riesgo la propia salud y el desarrollo pleno, cercenando sus propios derechos. Se recomienda profundizar este tipo de estudios para promover intervenciones oportunas en programas y proyectos destinados a orientar a los padres en aspectos relacionados con la constitución de los niños como sujetos de Derechos y Deberes.</p>

AbstractOBJECTIVE. The Functional Upper Extremity Levels (FUEL) is a new classification tool to assess a person’s upper-extremity functional and physical performance after sustaining a stroke. The aim of this preliminary study was to develop the tool and determine its content validity and interrater reliability.METHOD. Forty-four licensed occupational therapists ranging in years of experience from 6 mo to 16 yr participated in this study. A two-phase study was conducted: (1) constructing the FUEL and determining its content validity and (2) ascertaining its interrater reliability.RESULTS. We found that the FUEL had initial content validity and substantial interrater reliability (Fleiss κ = .754).CONCLUSION. The FUEL can be a useful clinical and research tool in occupational therapy for the assessment and classification of upper-extremity function for people after stroke. Further studies with larger samples and comparison studies with other similar tools are required to support the tool’s reliability and validity.

Published: October 2015

Abstract
OBJECTIVE. Engaging in food activities and maintaining identity are each important for productive aging. This study explored the role of food activities in identity maintenance among community-living older adults.
METHOD. We used a grounded theory approach to analyze data collected in semistructured interviews with 39 predominantly White, British older adults living in West London.
RESULTS. Two lifelong food identities—“food lover” and “nonfoodie”—were maintained in the processes of participation and maintenance and threat and compensation. The process change in meaning and identity explained the development of a third food identity—“not bothered”—when participants experienced being alone at the table, deteriorating health, and worry about the cost of food.
CONCLUSION. Food activities that are a pleasurable and important part of daily life contribute to the maintenance of important identities and mental well-being in older adults.

Authors: Boehm Nicole , Muehlberg Hannah , Stube Jan E. 
Published: October 2015

Abstract
OBJECTIVE. The objective of this study was to examine the effectiveness of delivering Managing Fatigue: A Six-Week Course for Energy Conservation via telehealth for a 70-yr-old man with poststroke fatigue (PSF).
METHOD. For this pilot case study, a questionnaire developed by the authors and the Patient-Reported Outcomes Measurement Information System Fatigue Short Form 7a were used for screening. The study was implemented via teleconference over an 8-wk period. The Fatigue Impact Scale (FIS) and the Canadian Occupational Performance Measure (COPM) were used to gather pretest and posttest data.
RESULTS. After the participant completed the course, decreased fatigue impact was noted on the FIS, and modestly improved occupational performance and satisfaction were evidenced by the COPM.
CONCLUSION. For this single participant experiencing PSF, performance and satisfaction on the COPM guardedly improved and fatigue impact decreased after participation in the energy conservation course offered by teleconference, a form of telehealth delivery. Further research is recommended with larger sample sizes.
Comparative Study of Personality Trait Characteristics and Reactivity in Schizophrenia Using a Film Clip Paradigm
Authors: Dinzeo Thomas J. , Sledjeski Eve , Durner Christopher , Docherty Nancy M. 
Published: October 2015

Abstract
The empirical examination of personality characteristics related to the experience of strong negative emotions and the associated physiological response may help account for idiosyncratic responses to life events in schizophrenia. The current study examines the relationship between levels of neuroticism and arousability and physiological and emotional reactivity during the viewing of film clips with differing emotional valance. Data were collected on emotional and cardiovascular and cortisol reactivity across experimental conditions for a sample of outpatients diagnosed with schizophrenia and a comparison group of nonpsychiatric controls. Levels of both neuroticism and arousability were significantly associated with increased negative emotion and physiological reactivity during the negative film clip task, although different patterns emerged across participant groups. Most notably, trait characteristics were inversely related to heart rate reactivity in patients but not controls. This relationship remained significant even after we controlled for disengagement coping behaviors. Cortisol response was not related to personality characteristics in either participant group. Findings were generally consistent with previous research, providing additional evidence for the role of trait characteristics in the response to events.

Published: October 2015

A taxa de aloimunização eritrocitária em pacientes politransfundidos pode atingir 50%, entretanto a frequência de anticorpos clinicamente relevantes em pacientes transfundidos não é perfeitamente conhecida, estimando-se que cerca de 1% dos pacientes são sensibilizados a cada unidade de hemácias transfundidas. O objetivo deste trabalho é relatar o caso de uma paciente de 11 anos de idade, portadora de ?–talassemia major, politransfundida, na qual foi detectada, em protocolo pré-transfusional, a presença de dois anticorpos anti-eritrocitários raros: anti-Colton b (anti-Cob) e anti-Lutheran 14 (anti-Lu14). Para o levantamento do histórico clínico-laboratorial da paciente, foi realizada pesquisa de prontuário arquivado no sistema de arquivos de um hospital-escola no qual a paciente é acompanhada. A fenotipagem eritrocitária em pacientes politransfudidos é essencial para minimizar os riscos de complicações devido à aloimunização e estimar a disponibilidade de sangue compatível. Assim, o relato do presente caso poderá contribuir para ampliar os conhecimentos sobre a real taxa de frequência de anticorpos anti-eritrocitários raros em paciente talassêmico.

Estudio paralelo del suicidio en el Ecuador como proceso ritual de significación
Authors: Campo Lorena 
Published: October 2015

Pese a que la muerte es un estado generalizable, no está exento de conflictos y divergencias al ser narrado socialmente. En este artículo se presenta la manera en que el fenómeno del suicidio puede estudiarse desde los sentidos otorgados al mismo desde la perspectiva de los actores sociales implicados dentro de un proceso ritual de significación. La muerte autoinflingida provoca diversas reacciones colectivas, de acuerdo al sujeto que lo interpreta y su contexto cultural, dando cuenta de esos contrastes explicativos. Es un tema tratado desde distintas disciplinas, geografías y temporalidades. En el caso específico de Ecuador abordar la temática, paralelamente desde dos perspectivas complementarias como la Antropología y la Psicología, es un intento por entender algo más del fenómeno multicausal que afecta a una parte importante de la población joven del país sudamericano.

Cisplatin belongs to the most widely used cytostatic drugs. The determination of the presence of the DNA-cisplatin adducts may not only signal the guanine-rich regions but also monitor the interaction reaction between DNA and the drug in terms of speed of interaction. In this work, the combined advantages of magnetic particles-based isolation/purification with fluorescent properties of quantum dots (QDs) and antibodies targeted on specific recognition of DNA-cisplatin adducts are demonstrated. The formation of a complex between magnetic particles with surface modified by anti-dsDNA antibody, cisplatin-modified DNA and QDs labelled anti-cisplatin-modified DNA antibody was suggested and optimized.
What Technology Skills Do Developers Need? A Text Analysis of Job Listings in Library and Information Science (LIS) from Jobs.code4lib.org
Authors: Maceli Monica 
Published: October 2015

Technology plays an indisputably vital role in library and information science (LIS) work; this rapidly moving landscape can create challenges for practitioners and educators seeking to keep pace with such change. In pursuit of building our understanding of currently sought technology competencies in developer-oriented positions within LIS, this paper reports the results of a text analysis of a large collection of job listings culled from the Code4lib jobs website. Beginning over a decade ago as a popular mailing list covering the intersection of technology and library work, the Code4lib organization's current offerings include a website that collects and organizes LIS-related technology job listings. The results of the text analysis of this dataset suggest the currently vital technology skills and concepts that existing and aspiring practitioners may target in their continuing education as developers.
Trastorno Específico del Lenguaje: Marcadores psicolingüísticos en semántica y pragmática en niños españoles

<p>The aim of this study is to determine which semantics and pragmatics markers best discriminate Spanish-speaking children with Specific Language Impairment (SLI) from children with typical language development. This study analyzes the performance of 31 Spanish-speaking children with SLI on a battery of 9 psycholinguistic tasks. The performance of the SLI children was compared with that of two subgroups of controls: aged-matched (CA) and linguistically matched (CL).</p><p>The data show that the SLI group performed more poorly than the CA subgroup on most of the tasks (8/9). However, the SLI group performance only was significantly worse that of the CL subgroup on one of the tasks. A first Discriminant Analysis SLI vs CA established canonical function with Sensitivity 93,5% and Specificity 87,1%. A second Discriminant Analysis SLI vs CL identified a canonical function with Sensitivity 77,4% and Specificity only 54,8%. One semantic task (Definition of words) and another pragmatic task (Scene language) appear to be the best variables for establishing an SLI profile in this psycholinguistics areas. Discuss the implications of these findings for the clinical diagnosis and speech-language pathology.</p>
