Abstract
Drilling wells in complex geological structures from offshore platforms, or onshore in areas with land access restrictions often creates complex S-shaped wells. In many such wells, high-angle doglegs cause problems with wireline key-seating, thus restricting reservoir access. When Logging While Drilling (LWD) data acquisition is not an option and Pipe-Conveyed Logging (PCL) is discarded because of its risky and time-consuming nature, many wells could end up without critical Formation evaluation data.
To overcome reservoir access challenges in the Sirikit Field in Thailand, a Through-Drill pipe Logging (TDL) technique has recently been introduced to complete formation evaluation. This method safely and effectively overcomes the complex well trajectories and associated wireline conveyance problems, such as key-seating. Slim 2.25" OD logging tools including Triple Combo (TC), Quad Combo (QC) and formation pressure tester and fluid sampler are deployed on wireline through open-ended drill pipe into open-hole without difficulties and with full well control maintained at all times.
A standard TDL operating procedure has been developed between wireline and drilling crews, allowing for safe and fast operations. The driller is able to have well control, with pipe being reciprocated regularly. Typically the drill pipe is run with a reamer shoe to allow borehole cleanout operations in the same run. The TDL deployement method is now a key component in the standard decision tree for data acquisition strategy in Sirikit Field and it has been successfully introduced in the Sirikit Field in May 2016. Since then, a total of 59 runs have been performed in 31 wells where wireline reservoir access problems were encountered, saving an estimated 1,240 hours of combined rig time not counting any potential wireline fishing jobs that would likely have occurred. A near 100% success rate is maintained, measured by reaching well TD and acquiring all desired wireline data. Petro physicist and geologists are no longer left without the crucial formation evaluation data they require for successful reservoir management.
This paper present a case study that clearly demonstrates that the TDL deployment technique can be very effective in providing safe and efficient wireline access to reservoir sections in S-shaped wells with risky wellbore conditions, where high-angle doglegs and key-seating would otherwise have restricted the ability to obtain Formation evaluation log data and fluid samples.

Abstract
The purpose of this paper is to share the challenges and engineering solutions in managing risk of using nitrogen as the refrigerant in the LNG (Liquefied Natural Gas) liquefaction process on a Floating LNG (FLNG). In December 2016, the first FLNG started to produce LNG 130 km offshore using Nitrogen Liquefaction Technology, which is also the first in the world. Multi-Component Refrigerant (MCR) is commonly used to liquefy natural gas worldwide in the LNG plants. However, the Nitrogen Liquefaction Technology has been selected in view of its inherently safer non-flammable non-corrosive property, simplified process and reduced refrigerant handling and storage onboard. As compared to MCR, the flammable hazard on the FLNG is reduced by adopting nitrogen as refrigerant. Nevertheless, during the course of engineering design, other risk that could potentially be posed by nitrogen was identified. The main concern is the brittle fracture and anoxia risk in the event of cryogenic nitrogen loss of containment. This leads to engineering challenges in terms of the process containment, structural impact, ability to detect, safe disposal and drain and lifesaving appliances, etc. This sharing can be the pioneer reference for other FLNG designs in particular the refrigerant system, the relevant risk management and the engineering solutions.
“Glocalized” Utopia, Community-Building, and the Limits of Imagination
Authors: Schiffer Steven Jay 
Published: March 2018

ABSTRACT
What happens when intentional communities break from lingering associations with socialism in favor of supposedly more savvy or self-conscious forms of utopianism? Attempts to grapple with globalizing neoliberalism, giving rise to “glocalized” utopia, highlight how ill-fitting the categorization of intentional communities as programmatic utopias is. Engagements with “everyday” utopianism in the face of an agency- and imagination-limiting globalizing neoliberalism suggest that in contemporary lived utopianism the everyday has become the program; contemporary utopianism in some North American intentional communities is defined by concerns for “raising consciousness” and “creating space”—efforts symbolic of the blending of programmatic and everyday utopianism. This article offers an ethnographic case study of this blended, glocalized form of utopianism, drawing on fieldwork to investigate how ecovillagers in the Yarrow Ecovillage make “everyday” life a site of self-conscious social reform. It then argues that glocalized utopia emerges when community aspirations for social reform confront neoliberal “recuperative capitalism.”

Authors: López Mario , Valenzuela Andrea , Carrasco Claudio 
Published: March 2018

Esta investigación evalúa las formas de ocupación en el territorio mapuche y sus procesos de transformación en la comuna de Arauco. La hipótesis plantea que se ha perdido la relación simbiótica natural-cultural entre el mapuche y su entorno. La metodología consistió en la caracterización del paisaje de manera cualitativa y cuantitativa en el contexto del grupo indígena, partiendo con 39 indicadores de primera generación, asignados y creados a la medida. Luego se formaron 8 componentes principales o indicadores de segunda generación, representando un área de análisis multidimensional, para luego ser agrupados nuevamente y formar un indicador de tercera generación o Índice de Sustentabilidad del Paisaje de Arauco (ISPA). Cada indicador fue jerarquizado dentro de su componente por medio del Proceso de Análisis Jerárquico (PAJ), resultando una cifra única para entender el estado de sustentabilidad de la comuna analizada en 4 períodos de tiempo (Siglo XVI, Siglo XVII, 1960 y
2016). El análisis de la información evidencia una pérdida de la condición simbiótica natural-cultural. Por último, se realiza la propuesta de una imagen objetivo, llevada a cabo con una sistematización de los resultados y la percepción actual de las comunidades mapuches por medio de talleres y entrevistas
donde se graficó el esquema de una unidad comunitaria mínima para un territorio cuantificado por hectáreas y porcentajes promediados según los resultados. La propuesta se enfoca en la visión y recuperación del territorio para lograr la Sustentabilidad del Paisaje Mapuche.
The Determinants of Working Capital Management in the Egyptian SMEs
Authors: Elbadry Ahmed 
Published: March 2018

Purpose– This paper explores the main determinants of working capital management in the Egyptian SMEs and explains its effect on working capital management. Also, I examine the relation between working capital management and SMEs' profitability and capital structure.Design/methodology/approach – The study sample include data for 138 SMEs working in Egypt and financed by the national bank of Egypt from 2010 to 2013. Data have been collected from SMEs financial statements for four years for each company. OLS regression models have been used to examine the effect of working capital determinants on working capital level measured by CCC. We used firm size and industry as control variables and robustness our results using full regression models for every year of analysis. All regression models were checked for normality, multicollinearity and hetroscedisticity. Findings – The main results reflect a negative and significant effect of SMEs profitability, tangible fixed assets, and leverage. Also, the industry represents a significant factor in determining the level of working capital in the Egyptian SMEs. Moreover, the effect of working capital management and SMEs profitability and capital structure decisions has been examined. The results reflect that the Egyptian SMEs follow an aggressive policy as businesses hold low level working capital which leads to high return and high degree of risk (measured by LEVERAGE).Research limitations/implications – The study limited to the Egyptian SMEs and financed by the National Bank of Egypt. Originality/value – The study explores the main determinants of working capital in the Egyptian SMEs and examined its effect on working capital management. Also, we examined the effect of working capital determinants on each component of working capital measured by cash conversion cycle. Moreover, I examined the effect of working capital on SMEs' profitability and capital structure decisions.

Simulated clinical experiences are an alternative to on-site clinical training. Focused simulations allow for teaching, clinical feedback, and adjustments in patient interaction strategies conducted in controlled real-time environments. Simulations allow nursing students to develop skill acquisition, improve critical thinking, problem-solving, and decision making especially when using a standardized patient (SP). The International Organization for Clinical Simulation and Learning defines and SP as an individual specifically educated to depict a patient or person with a particular condition or behavior in a realistic, consistent and repeatable method and educated to consistently represent a patient or person in a scripted situation to instruct, practice, and evaluate. While there is a plethora of information about the participants experience with the simulation process little is known about the SP’s personal experience. This paper discusses the standardized patient’s experience and the faculty viewpoints after several autism simulations were implemented.
Yoga research and therapy in India
Authors: Telles Shirley 
Published: March 2018

Yoga was originally intended for spiritual growth. However, nowadays there is an increasing trend to use yoga as an add-on-therapy. In India it is believed that all diseases arise as a result of conflict between our instinct and our intellect1. This is also important in using yoga to promote positive health and prevent disease. A number of examples are cited here. Healthy children were given yoga and physical therapy and their physical fitness, cognitive functiones and emotional well being were tested. Yoga improved their emotional well being. Yoga also helped children with Duchenne muscular dystrophy (a degenerative disease) by improving their quality of life and mental status2. Again the benefits were ascribed to the mental as well as the physical effects of yoga. Of course yoga has marked benefits in healthy obese adults to prevent diseases by increasing mental well being, reducing stress and improving sleep3. Yoga also reduced anthropometric indices and brought about changes in leptin and adiponectin levels in otherwise healthy adults4a,b. This change too, was believed to be related to mental changes, along with the physical. Finally yoga can help in various disorders in which a person feels pain and distress5a,b. Many of the effects are believed to be due to changes in the functions at the level of the cortex and thalamus6, as well as the autonomic nervous system7. However the mechanisms underlying the effects of yoga need to be explored more thoroughly.

Published: March 2018

Introduction: Men-Tsee-Khang in Dharamsala, India, formally known as the Tibetan Medical and Astrological Institute (TMAI), is dedicated to the teachings and practice of Tibetan medicine, which uses therapeutic agents in multi-ingredient formulas. Aim of the study: The aim of the present study was to identify formulas used at Men-Tsee-Khang for the treatment of neuropsychiatric disorders and to compare the Tibetan usage of particular ingredients with pharmacological data from the scientific database. Methods: Using ethnographic techniques and methods, five physicians were selected, and the interviews were conducted between July 2010 and February 2011. Results: A correlation was observed between central nervous system disorders and rLung, one of the three humors in Tibetan medicine, and 10 formulas used to treat the imbalance of this particular humor were identified. These formulas utilize 61 ingredients, including salts, animal products and plants. The 48 plant species identified in these formulas are traditionally used in Tibetan medicine and are deposited at the Men-Tsee-Khang Herbarium. Each formula treats several symptoms related to rLung imbalance, so the plants may have therapeutic uses distinct from those of the formulas in which they are included. Data from the scientific literature indicate that all of the formulas include ingredients with neuropsychiatric action and corroborate the therapeutic use of 75,6% of the plants. Conclusion: These findings indicate a level of congruence between the therapeutic uses of particular plant species in Tibetan and Western medicines.

Gouverner par des « coups de pouce » (nudges) : instrumentaliser nos biais cognitifs au lieu de légiférer ?
Authors: Flückiger Alexandre 
Published: March 2018

En visant la partie inconsciente et émotionnelle de notre esprit, les sciences affectives et comportementales ont démontré la possibilité d’orienter nos actions sans recourir à la contrainte. Dans ces conditions, la tentation était vive de chercher à exploiter les résultats de telles recherches pour gouverner nos conduites au lieu de légiférer. Par d’habiles « coups de pouce » (nudges), l’État devient ainsi l’architecte de nos choix (choice architect), chargé de créer un environnement incitant, à notre insu, à obéir comme il le souhaite. En d’autres termes, donner un « coup de pouce » revient à créer un environnement comportemental incitateur (choice architecture) offrant un contexte propice à l’adoption d’un comportement déterminé sans contrainte apparente.
Un tel mécanisme présente l’indéniable intérêt de contribuer à mettre en oeuvre les lois et les politiques publiques de manière plus souple. L’incitation doit en effet être préférée à la coercition si la première se révèle suffisamment efficace. Pourtant, la création d’environnements comportementaux incitateurs est un moyen possiblement très intrusif, susceptible de court-circuiter notre libre arbitre. Il reviendra donc aux autorités de ne retenir que ceux d’entre eux dont la nature n’est pas manipulatoire. Fondés sur une base légale, visant un intérêt public, proportionnés, conformes à la bonne foi, transparents et non discriminatoires, ces environnements ont en revanche toute leur place dans la panoplie d’un État de droit.

AbstractElectrocatalytic hydrogenation of acetylene to ethylene in aqueous electrolytes under ambient conditions faces efficiency and selectivity limitation due to the competitive formation of 1,3‐butadiene and hydrogen. In this study, the development of a copper nanoparticle/FeNC composite catalyst is reported through a simple mechanical grinding approach that demonstrates remarkable performance, achieving a highest ethylene Faradaic efficiency of 97.7% at 180 mA cm−2 and selectivity of 92.6% at 200 mA cm−2. Experimental investigations reveal that Cu atoms serve as the active sites, and the integration of FeNC improves the specific surface area through its 2D nanosheet morphology. Further analysis utilizing in situ Raman measurements coupled with theoretical calculations confirms that FeNC accelerates water dissociation to provide abundant protons and improving their transfer, thereby suppressing 1,3‐butadiene formation and elevating acetylene selectivity. Notably, the integration of FeNC also transforms the desorption of *C2H4 into an exothermic process, further facilitating ethylene production. Overall, this study introduces a simple and innovative preparation approach of composite catalysts for selective ethylene synthesis, expanding the application scope of Cu‐based FeNC materials in various electrocatalytic hydrogenation reactions.

AbstractThe solid additive strategy represents a simple yet effective approach to achieving high‐efficiency organic solar cells (OSCs) by enhancing the morphology of the active layer. In this study, a highly volatile solid additive, 2,4,6‐trichloro‐1,3,5‐triazine (TCT), is employed to modulate the morphology. Unlike other solid additives previously reported, TCT exhibits remarkable intermolecular interactions with both polymer donor and acceptor, offering two distinct advantages. Firstly, TCT notably enhances the crystallinity and molecular order of the blend film, subtly optimizing the fiber network structure within, thereby facilitating carrier transport and significantly improving the mobility of the blend film. Secondly, TCT stabilizes the bi‐continuous fibrous morphology of the polymer donor and acceptor, mitigating the morphological evolution of the active layer and enhancing device stability. Consequently, the D18:L8‐BO:TCT device exhibits a higher power conversion efficiency of 19.50% compared to the D18:L8‐BO device (18.13%). Furthermore, after 960 h of storage, the OSC device treated with TCT retains 90% of its initial PCE, significantly outperforming the D18:L8‐BO device (73%). This study presents a promising avenue for achieving high‐performance OSCs through manipulating the active layer morphology with solid additives.
