Rigging the Odds Against Climate Change
Authors: Barrow Ellen , Tarplee Ian 
Published: August 2017

Abstract
Climate change has enormous potential to impact on many types of ecosystem, not least our ocean environments. Melting ice caps, increasing sea temperatures and more extreme weather events mean that it is imperative that our marine-based infrastructure is resilient to withstand these challenges, both in the short-term and long-term future.
Offshore platforms are a haven for marine life. Have we considered how biological activity, arising as a result of climate change, could affect the structural integrity of the marine infrastructure we build? Does the design basis for marine infrastructure account for additional biological hazards arising as a result of increasing sea water temperatures? What are the implications for the life of the platform? Do current plans for decommissioning, and/or life extension, need to be reconsidered to avoid escalating and unforeseen costs? Climate change is unpredictable; we must factor in the likelihood of both extreme and gradual changes.
In this paper we tackle increasingly important issues: what would the impacts be on critical seawater abstraction points due to invasive species, excessive marine growth or jellyfish swarms? Would our oil platforms stand up to an extreme wave with many unaccounted for tonnes of marine growth? Would these additional tonnes of marine growth threaten structural integrity and mean additional millions to cover the costs of decommissioning the rigs? Will biologically induced hazards reduce the life of offshore assets and/or challenge assumptions for life extension of assets? We suggest that if engineers consider these potential, and highly likely, concerns at an early stage, timely and costly delays to operations and decommissioning may be avoided.
Using real examples we will explore practical solutions to the increasingly prevalent biological challenges facing marine infrastructure as a result of climate change. These practical challenges will be discussed with a focus on decommissioning and life extension of assets, taking into account unanticipated loads for lifting, increased problems regarding disposal of marine growth, further structural maintenance and the unwelcome costs these may all introduce.

Abstract
In 2012, a benchmarking exercise was conducted to assess the performance of Bonga wells, a Deepwater (DW) project in Nigeria. The review revealed that the average Bonga well ranked fourth Quartile when compared with similar DW wells globally. After reflecting on the benchmark results, the Bonga Wells team concluded that something drastic needed to be done urgently to reverse the trend otherwise future projects will become unattractive and the profitability of the Bonga Field will be impacted negatively. Late 2012, a clear steer was given by Bonga Wells Leadership to reverse the performance trend. The mantra for the team was to beat the best performance anywhere in the world and there was a very strong leadership commitment to make it happen. The team concluded with a target to deliver ‘best in class' wells consistently within 24 months.

Published: August 2017

Abstract
Remote control and automated systems affiliated with Tubular Running Operations have been in use for the past 15 years with varied levels of success. Unsuccessful implementations have not elicited solutions, nor have successful implementations translated into a thriving industry standard. Though the oil and gas industry has changed much over the past 15 years, some of the same implementation challenges still exist. Service providers tend to have a "scattershot" approach to automating everything, rather than a concerted focus on exploiting small successes to realize specific company goals. This factor may be due to differing attitudes throughout the organization, ranging from upper management to business development to engineers. This can lead to the inability to cultivate a culture of technical progression among operators commensurate with the technical progression of equipment. From the service provider's perspective, an unwillingness to learn new technical concepts among operators may yield a general indifference about their own relevance within an automated industry, while the end customer may remain skeptical of the need for automation and become dissatisfied with the overall cost and time needed to implement automated solutions. Historically, industry insiders tended to mistake automation's inability to yield operational efficiency immediately as a failure. Overlooked is the fact that even the most cleverly implemented automation realizes better operational efficiency over time, with constant improvements and further integration. Additionally, some clients fail to realize that control systems are inconsistent from rig to rig. The absence of standardization may stem from corporations assigning more value to the retention of trade secrets than to an industry-wide focus on standardization. The following paper will examine—from the Tubular Running Services (TRS) provider perspective—the challenges associated with developing and deploying remote control and automated equipment. It will also give pragmatic solutions towards the successful implementation of this technology and prove that automation is not solely a technical hurdle for engineering to overcome.

Authors: Khan Kaffayatullah , Khan Shaukat Ali , Saleem Muhammad Umair , Ashraf Muhammad 
Published: August 2017

Background:
Bentonite clays are widely used in a drilling operation and play a vital role as a drilling fluid. Bentonite clay mud performs several functions during the drilling operation and facilitates the drilling process.

Objective:
In this study, the locally available raw bentonite clays were investigated to evaluate its potential use as a mud for borehole drilling operation after its improvement with the additives.

Method:
Rheological properties such as plastic viscosity, yield point and gel strength were evaluated by using a viscometer and filtrate loss test was performed by using filter press on both locally available raw bentonite clays and the commercial bentonite named as Mill gel.

Results:
From the test results obtained for the up gradation of clays with the different beneficiating materials, the drastic increase in the plastic viscosity, yield point and gel strength has been observed. It shows that Xanthum gum produced better results for the improvement of rheological properties of such clays. Carboxymethyl cellulose and starch were used as additives and it has been observed that carboxymethyl cellulose has improved both viscosity and filtrate loss control, whereas starch muds have the best filtration control properties.

Conclusion:
Improved bentonite clays have rheological and filtration characteristics that have satisfied American Petroleum Institute specification at optimum conditions of clay. It was concluded that improved clays are the suitable material for the drilling operations and suitable to substitute commercial bentonite.

The World Wide Web has brought an enormous improvement in the lives of people, during the last couple of decades. E-commerce is a new area arisen during this evolutionary period and has changed the traditional trading approaches for selling products and services. It uses different techniques to discover a market trend and analyze the competitor’s activities by exploiting reviews’ information. On the other hand, potential customers, also, use the online opinion to make their purchase decision. Opinion mining and sentiment analysis are the most critical and fundamental domains of data mining which can be useful for variety its sub-domains such as opinion summarization, recommendation system and opinion spam detection. Opinion mining and all its sub-branches can be performed efficiently when there is a comprehensive understanding of the most effective features applied in those domains. To achieve the best results, we need to use the most proper set of features for different case studies in order to classification or clustering. To the best of our knowledge, there is no extensive study and taxonomy of variety range of features and their applications in opinion mining. In this paper, we do comprehensive investigation on various types of features exploited in variety sub-branches of opinion mining domain. We present the most frequent features’ sets including structural, linguistic and relation-based features as a complete reference for further opinion mining research. The results proved that using multiple types of features improve the accuracy of opinion mining applications.

Questioning the Past and Possible Futures: Digital Historiography and Critical Librarianship
Authors: Jacobs Heidi L.M. , Murgu Cal 
Published: August 2017

Historical digitization projects are transformative endeavours that attempt to negotiate and navigate a past's relationship to the present and the future. This article considers librarians' roles within the context of critical librarianship and digital historiography and argues for a more robust role for librarians within these transformative endeavours. Within the literature on digital humanities, there are recurrent assumptions that librarians' roles in digitization projects ought to be those of collectors, cataloguers, preservers, metadata creators, web designers, or programmers while the intellectual or theoretical "heavy lifting" falls to disciplinary partners like historians or literary scholars. In this article, we argue that librarians' digital historical work also needs to engage with "core historical questions" and with the act of asking critical questions about the larger cultural, social, and political issues inherent in digitization work.
A Queer/ed Archival Methodology: Archival Bodies as Nomadic Subjects
Authors: Lee Jamie Ann 
Published: August 2017

This article highlights the particular - embodied - ways in which the human record can be collected, organized, and preserved. Engaging both archival and queer theories, the understanding of body-as-archives and archives-as-body is instantiated in the oral history record from one genderqueer poet. This poet's narration can be understood as a nomadic one of multiplicities, undoings, and metamorphoses. The far-reaching possibilities of the ongoing histories of the simultaneous becoming and unbecoming - archived (un)becomings - are at play and embodied throughout this archived oral history. The archives can produce a dizzying effect through which, I argue, archivists can resist the urge to settle, to neatly organize, and to contain the archival records to consider new ways to understand and represent the dynamic (un)becomings. Through the interpretive frame of the nomadic, the archives can be understood as a site of (un)becomings and as a space that can hold moving living histories.

Published: August 2017

Al realizar una revisión, análisis e identificación de la arracacha (Arracacia xanthorrhiza Bancroft), algunos cronistas hacen referencia a aquellos alimentos y vegetales útiles, admitidos y apetecidos por los españoles o considerados alimentos asombrosos que describieron como de calidad y curiosidad exótica; en este caso inicialmente reportaron a la Arracacha esculenta, como una planta andina cultivada por los indios desde la más remota antigüedad, de la que se consume su raíz; historiadores hacen referencia a los muiscas, quienes cultivaban distintas clases de plantas, no es necesario hacer siembras propiamente dichas, se establece en huertos, en asocio; los indígenas muiscas la sembraban en lugares próximos a los de habitación y cumplieron un papel similar al quemodernamente presentan los cultivos de pancoger; tal es el caso de "las batatas" o del mismo "frijol". Esta tradición hoy en día conocida y estudiada como de economía campesina, contribuye a la seguridad alimentaria, el acceso a un alimento nutritivo y sano, este cultivo de importancia para muchas comunidades de pequeños productores de la región andina colombiana, entre ellas el departamento de Boyacá siendo el tercer productor después de Tolima y Norte de Santander. Para este trabajo de investigación, se partió de la necesidad de unificar e identificar el agroecosistema de arracacha Boyacá, a través de la aplicación de encuestas con un enfoque de investigación participativa y la observación directa. Este diagnóstico rural fue realizado con productores en los municipiosseleccionados y el Grupo de Investigación en Desarrollo y Producción Agraria Sostenible GIPSO de la Universidad Pedagógica y Tecnológica de Colombia; se describen los aspectos relevantes de este sistema de producción, a partir de la información recopilada sobre materiales cultivados, manejo agronómico y tecnologías locales de cultivo, iniciando desde el conocimiento tradicional de sus agricultores. Los resultados indicaron la existencia de más de diez materiales genéticos en Boyacá, (denominaciones locales), identificados con base en características morfológicas como forma y color de la raíz, color del follaje y el tallo. Es cultivada por pequeños agricultores en parcelas con áreas menores a 1 ha, adquiriendo a través de décadas, apreciables conocimientos en diferentes tópicos de producción.

Рак является одной из важнейших медицинских и социальных проблем, основным аспектом которой в ДНР, России и Украине остается недопустимо низкий уровень своевременной диагностики онкозаболеваний в I–II стадиях при удовлетворительной технической оснащенности медицинских учреждений.При своевременно выявленном раке в I–II хирургическое лечение в большинстве случаев приводит к полному выздоровлению. При этом экономическая нагрузка на органы здравоохранения значительно ниже.Применение методов скрининга крайне необходимо в ДНР, поскольку в настоящее время на момент установления диагноза более половины пациентов уже не подлежат радикальному лечению. В качестве методов доклинического выявления рака могут быть использованы достаточно доступные, недорогие и простые методики: эндоскопические исследования, ультразвуковое исследование, дерматоскопия, компьютерная томография, морфологическая верификация.При подготовке специалистов-онкологов и врачей других специальностей следует формировать онконастороженность при обследовании больных с различной патологией и осознание необходимости скрининга и ранней диагностики онкозаболеваний.Таким образом, существует необходимость обеспечения ранней диагностики рака с рациональным использованием технического оснащения лечебных учреждений, что обеспечивает высокие отдаленные результаты лечения.

В статье рассматривается современное состояние проблемы рака толстой кишки с инвазией в мочевой пузырь. Выделены два принципиально отличных метода оперативного лечения, такие как эвисцерация органов малого таза и мультивисцеральная резекция. Онкологические требования к обоим видам лечения – достижение R0 границы резекции, а также удаление опухоли единым блоком. Длительность эвисцерации органов малого таза варьирует от 3 до 8 часов, объем интраоперационной кровопотери – от 1,5 до 4,5л. Частота послеоперационных осложнений составляет от 35,0% до 69,6%. Послеоперационная летальность варьирует от 1% до 20%, местный рецидив от 14% до 67%. 5-летняя выживаемость составляет от 14% до 70%.
Средняя продолжительность комбинированной резекции толстой кишки с инвазией в мочевой пузырь 180 минут, интраоперационная кровопотеря в - 500 мл. Частота послеоперационных осложнений не превышают 31,6%. Послеоперационная летальность варьирует от 1,7% до 11,3%, частота местного рецидива - 30,1% , 5-летняя выживаемость составляет от 35,5% до 73,8%. Частота обструктивных резекций при данных оперативных вмешательствах составляет от 21,5% до 76,9%.
Проанализированные данные показывают необходимость разработки новых подходов к органсохраняющим операциям и улучшения качества и продолжительности жизни пациентов.
Assessment of Cardiovascular System Abnormalities in Patients with Advanced Primary Hyperparathyroidism by Detailed Echocardiographic Analysis: A Prospective Study
Authors: Mishra SK , Agarwal Amit , Mishra, Anand K , Kumar, Sudeep 
Published: August 2017

ABSTRACT

Aim
Recognizing the paucity of data regarding the incidence of cardiovascular abnormalities in severe primary hyperparathyroidism (PHPT), a prospective study was done for left ventricular (LV) systolic and diastolic function by echocardiography in patients with hyperparathyroidism (HPT) before surgery.

Materials and methods
A total of 18 consecutive patients with HPT and an equal number of age- and sex-matched controls were studied by two-dimensional and Doppler echocardiography.

Results
Patients with HPT had higher systolic and diastolic blood pressures (BPs). Despite severe bone disease, nephropathy, and vitamin D deficiency, none had metastatic calcification in myocardium. There was no significant increase in LV systolic dimensions and volume, but decreased ejection fraction (EF) and significant diastolic dysfunction were observed.

Conclusion
Despite an asymptomatic cardiac status, there were decreased EF and significant diastolic dysfunction. The HPT patients despite having severe disease, did not have metastatic calcification.
