El declive de un convento o el fin de un modelo de relaciones Iglesia, política y sociedad en Nueva Granada, 1820-1863
Authors: Plata Quezada Wiilliam Elvis 
Published: October 2014

Los años que van entre la Guerra de Independencia (1810-1819) y mediados del siglo XIX, corresponden a un período de grave crisis y declive de las comunidades y órdenes religiosas establecidas en el país. Tal crisis fue alentada al promoverse nuevas estructuras de corte moderno en las relaciones político–religiosas, que provocó asimismo la desarticulación interna de las órdenes religiosas existentes en la época. En este artículo, basado en fuentes primarias, se analizarán los principales elementos que constituyeron dicha crisis, a través del estudio de caso de la Orden Dominicana, siguiendo la hipótesis de que todo ello no representaba otra cosa que la rápida disolución del hasta entonces exitoso modelo de alianza entre los conventos y las élites criollas a través de vínculos corporativos y clientelistas, los cuales habían constituido la base del sistema de cristiandad colonial. Tras esta disolución quedó latente la necesidad de configurar un nuevo modelo de relaciones entre Iglesia, sociedad y Estado, que se va a gestar a partir de la Regeneración (1885-1900).The Decline of a Convent or End of a Pattern of Relationships Between Church, Politics and Society in New Granada, 1820-1863AbstractThe period between the Independence War (1810-1819) and the mid-nineteenth century, is a period of grave crisis and decline of communities and religious orders established in the country. This crisis was encouraged to promote new structures in modern cutting political-religious relations, which also led to the internal chaos of the religious orders. In this article, based on primary sources, the main elements that constituted the crisis will be analyzed through the case study of the Dominican Order, following the hypothesis that all this represent the rapid dissolution of the successful alliance model between the religious orders and the Creole elites through patronage and corporate bonds and had formed the basis of the system of colonial Christianity. After this solution was latent need to set up a new model of relations between church, state and society, which is going to take shape during the “Regeneracion” period (1885-1900).Keywords: Catholic Church, Dominicans, State, New Granada, Convents, 19 Century

Published: October 2014

Objectives. We evaluated the feasibility of incorporating integrated care (IC) for smoking cessation into routine treatment for posttraumatic stress disorder (PTSD) at Department of Veterans Affairs (VA) Medical Centers and the utility of the Learning Collaborative (LC) model in facilitating implementation. Methods. We conducted 2 LCs aimed at implementing IC for smoking cessation using multidisciplinary teams comprising 70 staff members from 12 VA PTSD clinics. Using questionnaires, we evaluated providers’ perceptions of the LC methodology and the effectiveness and feasibility of routine IC delivery. We assessed number of providers delivering and patients receiving IC using medical record data. Results. More than 85% of participating VA staff considered the LC to be an effective training and implementation platform. The majority thought IC effectively addressed an important need and could be delivered in routine PTSD care. All LC participants who planned to deliver IC did so (n = 52). Within 12 months of initial training, an additional 46 locally trained providers delivered IC and 395 veterans received IC. Conclusions. The LC model effectively facilitated rapid and broad implementation of IC. Facilitators and barriers to sustained use of IC are unknown and should be identified to understand how best to promote ongoing access to evidence-based treatment for smoking cessation in mental health populations.

Published: October 2014

Objectives. We examined associations between the relative and absolute availability of healthier food and beverage alternatives at food stores and community racial/ethnic, socioeconomic, and urban–rural characteristics. Methods. We analyzed pooled, annual cross-sectional data collected in 2010 to 2012 from 8462 food stores in 468 communities spanning 46 US states. Relative availability was the ratio of 7 healthier products (e.g., whole-wheat bread) to less healthy counterparts (e.g., white bread); we based absolute availability on the 7 healthier products. Results. The mean healthier food and beverage ratio was 0.71, indicating that stores averaged 29% fewer healthier than less healthy products. Lower relative availability of healthier alternatives was associated with low-income, Black, and Hispanic communities. Small stores had the largest differences: relative availability of healthier alternatives was 0.61 and 0.60, respectively, for very low-income Black and very low-income Hispanic communities, and 0.74 for very high-income White communities. We found fewer associations between absolute availability of healthier products and community characteristics. Conclusions. Policies to improve the relative availability of healthier alternatives may be needed to improve population health and reduce disparities.

Published: October 2014

Objectives. We describe the impact of the Step On It! intervention to link taxi drivers, particularly South Asians, to health insurance enrollment and navigate them into care when necessary. Methods. Step On It! was a worksite initiative held for 5 consecutive days from September 28 to October 2, 2011, at John F. Kennedy International Airport in New York City. Data collected included sociodemographics, employment, health care access and use, height, weight, blood pressure, and random plasma glucose. Participants were given their results, counseled by a medical professional, and invited to participate in free workshops provided by partner organizations. Results. Of the 466 drivers participated, 52% were uninsured, and 49% did not have a primary care provider. Of 384 drivers who had blood pressure, glucose, or both measured, 242 (63%) required urgent or regular follow-up. Of the 77 (32%) requiring urgent follow-up, 50 (65%) sought medical care at least once, of whom 13 (26%) received a new diagnosis. Of the 165 (68%) requiring regular follow-up, 68 (41%) sought medical care at least once, of whom 5 (7%) received a new diagnosis. Conclusions. This study provides encouraging results about the potential impact of an easy-to-deliver, easily scalable workplace intervention with a large, vulnerable population.

Authors: Underhill Kristen , Dumont Dora , Operario Don 
Published: October 2014

We summarized and appraised evidence regarding HIV prevention interventions for adults with criminal justice involvement. We included randomized and quasi-randomized controlled trials that evaluated an HIV prevention intervention, enrolled participants with histories of criminal justice involvement, and reported biological or behavioral outcomes. We used Cochrane methods to screen 32 271 citations from 16 databases and gray literature. We included 37 trials enrolling n = 12 629 participants. Interventions were 27 psychosocial, 7 opioid substitution therapy, and 3 HIV-testing programs. Eleven programs significantly reduced sexual risk taking, 4 reduced injection drug risks, and 4 increased testing. Numerous interventions may reduce HIV-related risks among adults with criminal justice involvement. Future research should consider process evaluations, programs involving partners or families, and interventions integrating biomedical, psychosocial, and structural approaches.

Published: October 2014

Objectives. We examined whether the timely initiation of antiretroviral therapy (ART) differed by race and comorbidity among older (≥ 50 years) people living with HIV/AIDS (PLWHA). Methods. We conducted frequency and descriptive statistics analysis to characterize our sample, which we drew from 2005–2007 Medicaid claims data from 14 states. We employed univariate and multivariable Cox regression analyses to evaluate the relationship between race, comorbidity, and timely ART initiation (≤ 90 days post-HIV/AIDS diagnosis). Results. Approximately half of the participants did not commence ART promptly. After we adjusted for covariates, we found that older PLWHA who reported a comorbidity were 40% (95% confidence interval = 0.26, 0.61) as likely to commence ART promptly. We found no racial differences in the timely initiation of ART among older PLWHA. Conclusions. Comorbidities affect timely ART initiation in older PLWHA. Older PLWHA may benefit from integrating and coordinating HIV care with care for other comorbidities and the development of ART treatment guidelines specific to older PLWHA. Consistent Medicaid coverage helps ensure consistent access to HIV treatment and care and may eliminate racial disparities in timely ART initiation among older PLWHA.

Abstract
To be alerted in determining early warning signs in well control is one of the most important to wellbore safety. Careful observance and positive reaction to these signs will keep the well under control and prevent the occurrence of a well flow situation.
Developing an accurate ultrasonic caliper with a special design helps the drilling engineer not only to detect a kick in real time drilling but also monitor the wellbore shape and profile.
4D image of the borehole is the result of ultrasonic calipers measurement, which helps the driller to make proper decisions such as reaming a critical zone, changing the flow rate to reduce erosion or modifying the string rotation speed to reduce vibrations and also detecting a kick when an influx enter to the borehole while drilling.
This paper reviews tests and experiments which have been performed by using an accurate ultrasonic caliper sensor in different drilling fluids (Water based mud) and wellbore conditions. Results show that the new design of the caliper tool increases the accuracy of the measurement by recording the sound velocity under downhole condition.
To simulate the kick condition, pressured air was injected while measuring borehole profile to simulate a kick situation. According to the results, with the special design of the tool it is possible to detect the kick while drilling as well as during wellbore diameter measurement procedure under downhole condition.

Abstract
In a carbonate field, a gas injection scheme has been assessed to improve oil recovery through pressure maintenance and miscible displacement. The potential study assumed sequential application of several gas injection concepts: Raw Gas Injection (RGI) and Acid Gas Injection (AGI). Flow simulation studies of these concepts revealed a variety of compositional changes to the in-situ fluid depending on the injection scheme and composition of the injected gases. Compositional change is a common trigger of asphaltene instability; therefore, to ensure a robust gas injection development, it is important to evaluate the risk of asphaltene deposition. Due to high H2S concentrations in potential developments, it is difficult to take an experimental approach for evaluating gas-mixed asphaltene flow assurance. Hence, this paper will focus on one AGI scenario, and present how AGI impacts asphaltene precipitation behavior through numerical modeling analysis. Based on the asphaltene model established by applying Cubic Plus Association (CPA) equation of state (EoS), which was calibrated with the experimental measured asphaltene onset pressure (AOP), a new Binary Interaction Parameters (BIP) correlation between H2S and hydrocarbons was incorporated to evaluate variation of asphaltene precipitation envelope (APE) with periodical compositional change observed from the AGI flow simulation. Acid Gas (AG) was assumed to be 90mol% H2S and 10mol% CO2. The produced fluid H2S concentration used in this study was assumed to be ~15mol%. During this study, H2S concentration was observed to increase up to 76mol% at a well located near AG injectors after long term flow simulation. In the APE sensitivity analysis that was independently conducted for each composition of H2S and CO2, the asphaltene model revealed the base APE shrunk as the H2S concentration increased while it expanded as the CO2 concentration increased. As a result for the mixed compositions, the opposing effects on the APE offset each other; the AG addition produced a subsequent shrinking of the APE. In summary, this work supported acid gas injection from a thermodynamically asphaltene flow assurance point of view.

Abstract
The reliability of the production is essential in offshore operations. Producing a well at its maximum rate is important everywhere. This is often compromised by having sand and fines production which not only plugs the wells and reduce production rate but also erode the equipment and settle in surface vessels. This paper describes a case history where an operator was faced with a well that was rate limited because of fines and sand production. An advanced sand control chemistry system was proposed and a treatment was designed. In April 2013, the treatment was performed by bullheading down the production tubing using rate diversion. Extensive engineering was involved in the candidate selection and planning the operational aspects of the treatment. The execution of the treatment was divided into stages – sand clean out, performing step rate test, pre-job modeling and pumping the treatment as per the design. After the treatment, the well was flowed and tested at almost three times the original maximum sand-free rate (MSFR) at an increased choke without sand production. The well has now been flowing for more than a year, at significantly higher rate than the previous MSFR sand free. This paper describes the chemistry of the sand conglomeration, design consideration, execution and the effect on well performance.

Abstract
Oilfield produced water often contains high levels of total dissolved solids (TDS) in addition to precipitates, suspended particles, and hydrocarbons. The main components of the dissolved solids include sodium, calcium, and magnesium salts. The combination of the high salinity and high hardness in produced water can be very damaging to many types of fracturing fluids that are commonly formulated with fresh and clean water. It is usually costly to treat high-TDS produced water to such an extent that it can be safely and stably used to formulate fracturing fluids. Meanwhile, it is also expensive to dispose of produced water by underground deep well injection or to transport produced water for disposal at a commercial oilfield wastewater disposal facility. On the other hand, fresh water for formulating fracturing fluids is becoming more costly and more difficult to obtain in many oil/gas production areas. Fluid systems have therefore been highly desirable and sought after that can be formulated directly with high-TDS water and perform well at high temperature of 275 °F or above.
A group of fracturing fluids was successfully identified recently that performed very well at high temperatures when formulated with untreated high-TDS produced water. The produced water tested had TDS up to about 330k mg/L and hardness (calcium carbonate equivalent) up to about 64k mg/L. The fracturing fluids comprised of organometallic-crosslinked derivatized polysaccharides. In one typical example, the viscosity stayed above 100 cP (at 100/s shear rate) for about 80 minutes at 275 °F recorded for a fracturing fluid prepared with untreated produced water with TDS of about 300k mg/L and hardness of about 50k mg/L. The magnitude and lifetime of the fluid viscosity were dependent on a number of factors such as the produced water TDS and hardness, test temperature, polymer loading, fluid pH, etc. The fracturing fluids also showed minimum damage to the formation or proppant pack tested. In a typical proppant pack conductivity test at 250°F, the retained conductivity was about 90% for the fracturing fluid mixed with appropriate amount of oxidative breaker.
The outstanding performances and the underlying mechanisms of the high-temperature fracturing fluids prepared with untreated extremely high-TDS and hard produced water will be discussed, and the field-related laboratory test results will be presented.

Abstract
We present an inversion-based method for petrophysical interpretation in a vertical or slightly deviated well that integrates flexural wave dispersion data from a sonic dipole tool, and resisitivity data from a tri-axial array-induction tool. At each logging depth, the inversion solves for radial profiles of water saturation and porosity extending several feet from the wellbore. Radial changes in water saturation represent the effect of mud-filtrate invasion, while radial changes in porosity represent the effect of mud-fines migration or mechanical breakdown of rocks. Petrophysical transforms specific to the formation lithology are used to map water saturation and porosity to elastic velocities and resistivity, which constitute the input to electromagnetic and sonic tool response simulators. Radial profiles of formation properties are estimated by minimizing the mismatch between the measured and simulated data using an inversion workflow. The workflow is designed taking into account complementary sensitivities of the flexural and induction measurements to improve inversion robustness.
We benchmark the inversion workflow for two fluid-lithology configurations relevant to deepwater offshore environments. The first configuration corresponds to gas-bearing sandstone drilled with oil-base mud, where the effective elastic properties are governed by the Gassmann fluid substitution petroelastic transform. The second configuration corresponds to oil-bearing carbonate drilled with oil-base mud, governed by the Self-Consistent Effective Medium (SCEM) petroelastic transform. For various near-wellbore invasion and mechanical alteration scenarios, the inversion reconstructs the radial formation properties extending up to five feet from the wellbore. The results demonstrate the efficiency, robustness, and accuracy of the inversion for application to challenging formation evaluation scenarios.

Abstract
Operators in the oil and gas industry are leading the way in the development and application of drilling optimization systems, allowing them to collaborate more effectively with service companies and improve drilling economics. They have combined their efforts with those of large equipment manufacturers that have extensive knowledge of solutions provided by advanced technology. Together, these entities can address the drilling challenges of each application, and establish new key performance indicator's that push the current boundaries.
Hess's optimization program is a drilling specific approach to the continuous improvement cycle. It adopts key elements from rate of penetration (ROP) management programs, lean manufacturing concepts and the drilling needs and practices of the operator. The program uses the Plan, Do, Check, Adjust (PDCA) as the four basic phases, with additional drilling specific activities covered in each step. Multiple downhole dynamics recorders validated the improvement process by monitoring bottomhole assembly (BHA) characteristics and operating practice effectiveness. Key performance indicators (KPIs) were established based on vibration levels from the downhole dynamics recorders, drilling hours, and interval hours.
A five well test program demonstrated the importance of program tools such as a driller's roadmap. A benchmark well was drilled and refined with regular drilloff tests. The BHA characteristics, operating practices, and drill bits were identified as the ROP limiters after analyzing the KPIs. This resulted in inconsistent runs and vibration damage to the drill-bit cutting structures. A working "driller's roadmap" was refined from the benchmark well to encourage a consistent approach to operating practices. Tests with three basic BHA configurations identified drilling system vibration characteristics and were then optimized to yield the best results.
ROP limiters identified by data analysis were addressed with significant adjustments to the BHA and operating parameters as the PDCA cycles progressed. A lessons learned catalog compiled during the optimization process documented key changes and performance impacts. The optimization cycle yielded an average 33 hour reduction in drilling time per well for the first pad in the process when compared to the rig's benchmark well. This resulted in a savings of about USD 88,335 per well, for a total savings of USD 353,340 for the first pad.
The optimization project is currently continuing in this field to fine tune the driller's roadmap. Improved performance and cost savings were sustained throughout the optimization process with larger gains to be realized in future drilling.
