Abstract
Upper Zubair Horizontal wells in North Kuwait pose a unique challenge; the challenge of building angle at High DLS, to achieve horizontal profile within short section of TVD. While normal DLS in Horizontal wells had been in the range of 5–7 deg. /100ft. in the 8½" section, the planned DLS to achieve the horizontal in upper zubair required a Build of 10–11 deg. /100 ft. This exceeded the capacity of normal Rotary Steerable Systems and it was something which was never attempted before in the entire Middle East region. Kuwait Oil Company strived for technological solutions and successfully carried out the job.
The need for sharp DLS arises primarily to counter the complications from formations in the section previous to it. High angle of inclination through shaly formations compounded with total loss, leads to quick destabilization of the hole creating an unstable hole. These issues enforce a strategy of not building beyond 40° inclination at the casing point, leaving the onus of building to horizontal in a short section of TVD. Completion strategies with ICD and Swell Packers in the lateral further tightened these requirements to a very smooth curve.
With proper operational control, the curve section was drilled with a proprietary RSS along with a specialized bit, cased and cemented successfully. Later the successful deployment of a stiff ICD completion proved the portability of this success to other challenging projects. The total savings realized on account of lesser directional work is over $700,000 US.
The paper outlines the planning efforts, risk assessment and operational details in achieving success. With capabilities of reaching DLS of 15°/100 ft. through these special RSS systems, new vistas have opened up for drilling of such challenging profiles. Sharper profiles with lower Kick-Offs could have huge potential for optimization in terms of lower directional costs and cycle times.

Background Permanent stimulation of the peritoneum during peritoneal dialysis (PD) is likely to result in increased expression of genes encoding proteins involved in inflammation and tissue remodeling. Peritoneal fibrosis and neoangiogenesis may develop. Objective To assess highly expressed genes potentially involved in peritoneal alterations during PD treatment using an animal model. Methods A PD catheter was implanted in 36 male Wistar rats after 70% nephrectomy. The rats were divided into 3 groups, exposed to dialysis solution for 8 weeks, and sacrificed 2 weeks later. Group B was exposed to a buffer, group D was exposed to a 3.86% glucose-based dialysis solution, and in group D+H, a second hit of intraperitoneal blood on top of the dialysis solution was given to induce the development of peritoneal sclerosis. Before sacrifice, peritoneal function was assessed. Omental tissue was obtained for analysis of gene expression using RT-qPCR. Results Fibrosis scores, vessel counts, and peritoneal function parameters were not different between the groups. Genes involved in the transforming growth factor beta signaling pathway, cell proliferation, angiogenesis, and inflammation were more expressed ( p < 0.05) in the D+H group. Almost no differences were found between the control groups. We identified 4 genes that were related to peritoneal transport. Conclusion Already a mid-term peritoneal exposure, when no microscopical and functional alterations are present, provokes activation of gene pathways of cell proliferation, fibrosis, neoangiogenesis, and inflammation.

Published: May 2016

Background Although technique failure is a key outcome in peritoneal dialysis (PD), there is currently no agreement on a uniform definition. We explored different definitions of PD technique failure using data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. Methods We included 16,612 incident PD patients in Australia and New Zealand from January 1998 to December 2012. Different definitions of technique failure were applied according to the minimum number of days (30, 60, 90, 180, or 365) the patient received hemodialysis after cessation of PD. Results Median technique survival varied from 2.0 years with the 30-day definition to 2.4 years with the 365-day definition. For all definitions, the most common causes of technique failure were death, followed by infectious complications. The likelihood of a patient returning to PD within 12 months of technique failure was highest in the 30-day definition (24%), and was very small when using the 180- and 365-day definitions (3% and 0.8%, respectively). Patients whose technique failed due to mechanical reasons were the most likely to return to PD (46% within 12 months using the 30-day definition). Conclusions Both 30- and 180-day definitions have clinical relevance but offer different perspectives with very different prognostic implications for further PD. Therefore, we propose that PD technique failure be defined by a composite endpoint of death or transfer to hemodialysis using both 30-day and 180-day definitions.

Abstract
Abdominal aortic aneurysm is a dynamic vascular disease characterized by inflammatory cell invasion and extracellular matrix degradation. Damage to elastin in the extracellular matrix results in release of elastin-derived peptides (EDPs), which are chemotactic for inflammatory cells such as monocytes. Their effect on macrophage polarization is less well known. Proinflammatory M1 macrophages initially are recruited to sites of injury, but, if their effects are prolonged, they can lead to chronic inflammation that prevents normal tissue repair. Conversely, anti-inflammatory M2 macrophages reduce inflammation and aid in wound healing. Thus, a proper M1/M2 ratio is vital for tissue homeostasis. Abdominal aortic aneurysm tissue reveals a high M1/M2 ratio in which proinflammatory cells and their associated markers dominate. In the current study, in vitro treatment of bone marrow–derived macrophages with EDPs induced M1 macrophage polarization. By using C57BL/6 mice, Ab-mediated neutralization of EDPs reduced aortic dilation, matrix metalloproteinase activity, and proinflammatory cytokine expression at early and late time points after aneurysm induction. Furthermore, direct manipulation of the M1/M2 balance altered aortic dilation. Injection of M2-polarized macrophages reduced aortic dilation after aneurysm induction. EDPs promoted a proinflammatory environment in aortic tissue by inducing M1 polarization, and neutralization of EDPs attenuated aortic dilation. The M1/M2 imbalance is vital to aneurysm formation.

Abstract
Gram-negative bacterial pneumonia is a common and dangerous infection with diminishing treatment options due to increasing antibiotic resistance among causal pathogens. The mononuclear phagocyte system is a heterogeneous group of leukocytes composed of tissue-resident macrophages, dendritic cells, and monocyte-derived cells that are critical in defense against pneumonia, but mechanisms that regulate their maintenance and function during infection are poorly defined. M-CSF has myriad effects on mononuclear phagocytes but its role in pneumonia is unknown. We therefore tested the hypothesis that M-CSF is required for mononuclear phagocyte-mediated host defenses during bacterial pneumonia in a murine model of infection. Genetic deletion or immunoneutralization of M-CSF resulted in reduced survival, increased bacterial burden, and greater lung injury. M-CSF was necessary for the expansion of lung mononuclear phagocytes during infection but did not affect the number of bone marrow or blood monocytes, proliferation of precursors, or recruitment of leukocytes to the lungs. In contrast, M-CSF was essential to survival and antimicrobial functions of both lung and liver mononuclear phagocytes during pneumonia, and its absence resulted in bacterial dissemination to the liver and hepatic necrosis. We conclude that M-CSF is critical to host defenses against bacterial pneumonia by mediating survival and antimicrobial functions of mononuclear phagocytes in the lungs and liver.

Authors: Asadian Leila , Haddadi Kaveh , Aarabi Mohsen , Zare Amirhossein 
Published: May 2016

Objectives This study aimed to determine the prevalence of diabetes mellitus in patients with spinal stenosis and lumbar vertebral disk degeneration, and the correlation of diabetes with these diseases. Study Design This is a cross-sectional study. Methods This case–control study was performed during 2012–2014 with 110 patients suffering from lumbar spinal stenosis and 110 patients with lumbar disk herniation, who were diagnosed using clinical and radiological evidences. Additionally, 110 participants who were referred to the clinic and did not show clinical signs of degenerative diseases of the lumbar spine entered the study as a control group. Demographic data and medical histories of the patients were collected using checklists. Results A total of 50 patients (15.2%) were diagnosed with diabetes, which comprised 32 (29.1%) in the stenosis group, 7 (6.4%) in the lumbar disk herniation group, and 11 (10%) in the control group. The prevalence of diabetes in women with spinal stenosis and women with lumbar disk herniation was 35.9% and 10.3%, respectively, whereas prevalence of diabetes in women was 10.9% in the control group. This difference was statistically significant in the spinal stenosis group in comparison with the controls ( P < 0.0001). Conversely, no significant difference was found in men. Conclusions There is an association between diabetes and lumbar spinal stenosis. Diabetes mellitus may be a predisposing factor for the development of lumbar spinal stenosis.

Authors: Salles Arghavan , Mueller Claudia M. , Cohen Geoffrey L. 
Published: May 2016

ABSTRACT

Female residents in surgical training may face stereotype threat. The awareness of negative stereotypes about surgical ability based on gender may heighten stress and thus reduce performance.Background

The main objective of this study was to assess the effectiveness of a brief stress-reducing writing exercise, known as a values affirmation, to mitigate the negative effects of stereotype threat on the performance of female surgical residents.Objective

This is a randomized, controlled trial in which 167 residents were invited to participate. A total of 45 resident volunteers, including 18 women, were randomized to the affirmation condition or the no-affirmation condition. We administered a values affirmation intervention and measured clinical evaluations data both prior to and 6 months after the intervention.Methods

Women benefited from the affirmation. Women who had participated in the affirmation exercise earned higher clinical evaluation scores than those in the control condition (B = 0.34, P &lt; .05). For men, performance did not differ by affirmation condition (B = –0.20, P = .35).Results

Our findings suggest a benefit of values affirmation for women in surgical training, as measured by performance on clinical evaluations. This suggests that a brief psychological intervention may improve on-the-job performance for women in surgery, an underrepresented group.Conclusions

Problem analysis is half the work. Cooperation and innovation in the struggle against subversive criminality
Science and practice are largely agreed on the importance of interorganizational cooperation in the approach of tackling complex societal problems. Organization transcending innovation through this type of cooperation however appears to be complicated. Based on an analysis of the literature about partnerships, the authors distinguish three challenges: coping with the tension between old and new accountability structures, building good working relationships and developing capabilities for problem-oriented working. Starting from these insights they designed action research into problem-oriented partnerships in the safety domain (safety chain). Their main question was: what is the most important obstacle for innovation through problem-oriented interorganizational cooperation? Over a period of nine months, they watched eight teams of professionals from different organizations. Their task was to develop and implement innovative approaches to tackle persistent organized crime. Although all three challenges identified in the literature indeed played a prominent role, problem diagnosis and problem definition appeared to be the main obstacle for the teams. In this article the authors describe the action research and explore, on the basis of the results and the literature, how partnerships could cope in practice with the challenge of problem definition and problem analysis. They conclude the article with suggestions for the design of a follow-up round of the action research.
Likelihood testing of seismicity‐based rate forecasts of induced earthquakes in Oklahoma and Kansas
Authors: Moschetti M. P. , Hoover S. M. , Mueller C. S. 
Published: May 2016

AbstractLikelihood testing of induced earthquakes in Oklahoma and Kansas has identified the parameters that optimize the forecasting ability of smoothed seismicity models and quantified the recent temporal stability of the spatial seismicity patterns. Use of the most recent 1 year period of earthquake data and use of 10–20 km smoothing distances produced the greatest likelihood. The likelihood that the locations of January–June 2015 earthquakes were consistent with optimized forecasts decayed with increasing elapsed time between the catalogs used for model development and testing. Likelihood tests with two additional sets of earthquakes from 2014 exhibit a strong sensitivity of the rate of decay to the smoothing distance. Marked reductions in likelihood are caused by the nonstationarity of the induced earthquake locations. Our results indicate a multiple‐fold benefit from smoothed seismicity models in developing short‐term earthquake rate forecasts for induced earthquakes in Oklahoma and Kansas, relative to the use of seismic source zones.
Control of the Hydrophilic/Hydrophobic Behavior of Biodegradable Natural Polymers by Decorating Surfaces with Nano‐ and Micro‐Components
Authors: de Oliveira Gama Renata , Bretas Rosario E. S. , Oréfice Rodrigo Lambert 
Published: May 2016

AbstractPackaging materials based on natural polymers are becoming popular because these polymers are derived from renewable resources and can display biodegradability. However, natural polymers are typically highly hydrophilic, and packaging films produced with them can absorb water, leading to dimensional changes and reductions in mechanical properties. In this work, films of thermoplastic starch (TPS) and blends of TPS/low‐density polyethylene (LDPE) were prepared, and their surfaces were decorated to alter their hydrophilic characteristics. Micro‐ (polymer microspheres) and nano‐components (polycaprolactone electrospun nanofibers) were deposited on the surface of starch and its blends with LDPE. Nanofibers containing silver sulfadiazine were also used to decorate the starch and its blends to change the topography (evaluated by SEM and atomic force microscopy) and to provide anti‐bacterial properties. High values of contact angle (CA) and low values of CA hysteresis were measured for the modified surfaces, including a CA higher than 150° and a hysteresis lower than 10°. Therefore, it was demonstrated that the intrinsically hydrophilic surfaces of biodegradable natural polymers could be altered by creating topographical patterns through decoration with nano‐/micro‐components to generate hydrophobic and even superhydrophobic features that can be useful in minimizing the water absorption of these materials.
Swampscott in International Context: Expanding Our Ecology of Knowledge
Authors: Sonn Christopher C. 
Published: May 2016

AbstractIn this paper, I offer reflections as someone from outside the United States about the Swampscott conference. I refer to Fryer and Fox's (The Community Psychologist, 24, 2014, 1) critique of the “Swampscott discourse” and its role in fixing the birthplace of community psychology. While the critique is important, I note the growing references to international community psychology and the need to view the discipline as a product of social political realities in different contexts, as well as dynamics of dominance and marginality in knowledge production in psychology. The work in the Global South presents opportunities to contribute to developing a decolonizing community psychology through expanding the ecology of knowledge.

Published: May 2016

ABSTRACTA thin Pt layer on fluorine‐doped tin oxide (FTO) glass is commonly used as the counter electrode (CE) for dye‐sensitized solar cells (DSCs). We have investigated thin layers on FTO glass made from spherical polypyrrole (PPy)–poly(styrene sulfonate) (PSS) nanocolloidal particles with and without treatment of CuBr2and used them as CEs. The colloidal polymer composite (PPy:PSS) was spin‐coated at 4000 rpm, and PPy:PSS multilayer (one, three, five) films were employed as the CEs. Aqueous solutions of CuBr2(0.5Mand 1M) were coated onto the multilayer CEs, which increased the efficiency of DSCs. When compared with the untreated PPy:PSS counter electrodes, the CuBr2‐treated PPy:PSS films showed lower charge‐transfer resistance, higher surface roughness, and improved catalytic performance for the reduction of. The enhanced catalytic performance is attributed to the interaction of the superior electrocatalytic activity of PPy:PSS and CuBr2salt. Under standard AM 1.5 sunlight illumination, the counter electrodes based on a single‐layer PPy:PSS composite with 0.5Mand 1MCuBr2salt treatment demonstrated power conversion efficiencies (PCE) of 5.8% and 5.6%, respectively. These values are significantly higher than that of the untreated PPy:PSS CE and are comparable with that of a Pt CE. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2016,133, 43772.
