Integrated Field Development: Process and Productivity
Authors: Sauve Robert , Lindvig Thomas , Stenhaug Morten , Holyfield Simon 
Published: April 2019

Abstract
Field development complexity in today's subsea industry is ever increasing; prospects tend to be smaller while located in deeper waters with deeper well targets, located farther from shore, and in colder regions. As a result, sanctioning projects in the current oil price environment is challenging and adopting efficient field development planning (FDP) processes is critical for project viability. This paper describes a fast-track, collaborative field development process to address these needs.
This fast-track field development process has been used with great success on numerous projects worldwide. The paper describes how the process integrates layout development and equipment selection with a fully integrated, holistic fluid flow simulation and establishes an excellent collaboration platform for the development team, fully enabling close interaction between teams that traditionally would not work closely together.
The paper demonstrates how experience gathered to date has clearly shown how the fully integrated approach to field development is crucial for the optimal development of the concept and how the result provides the highest return on investment.
Subsea production system and subsea umbilical, riser, and flowline specialists now work closely together with reservoir, production, and drilling engineers, ensuring the development of optimal solutions earlier in the FDP process and simultaneously enabling the teams to overcome the challenges that have previously been imposed by the segregation of different technical disciplines. The paper shows how key features of this process enable ultra-rapid scenario generation—a much shorter time from initial layout development to life-of-field production profiles—and how the process can be used to maximize overall economic performance for the project.

Abstract
The purpose of this paper is to demonstrate the characteristics and superiority of new SMR process by comparison with competitive proven technologies such as single mixed refrigerant (SMR) and dual mixed refrigerant (DMR) and showing stable operation without changing the MR composition under various feed stream conditions.
The new process has been developed based on SMR process that is used on current LNG production market to get higher performance showing the following attractive features in addition to the advantage of typical SMR process. ✓Achievement of Efficiency Enhancement by application of Advanced Vessel Economizer, Optimization of operating condition and Semi-DMR technologies✓Stable operation without changing the MR composition under various feed stream composition✓Compact configuration, easy operation and maintenance and low OPEX and CAPEX due to minimal equipment
Two case studies were conducted to demonstrate the above features.
The first case study is to compare the new SMR process with commercialized SMR and DMR process targeting at 3.5MTPA LNG production. As a result, the new SMR process showed 20.6% higher production efficiency than SMR-II Process [1] and 5.7% better than DRM process [2]. This means that less OPEX is required for the new liquefaction process. Also, the new liquefaction process required fewer equipment than the LNG SMR-II Process [1] and about half the number of equipment required than the LNG DMR Process [2], which means less CAPEX.
The second case study was conducted in the variation of actual feed composition such as typical case, high inert, low inert, rich gas and it is verified that new SMR process operated stably without significant change of the MR composition under various feed stream composition. Through two case studies, the features of new liquefaction process and superior performance were demonstrated.
Legados, peregrinos del tiempo, memorias ocultas: una mirada transgeneracional a través del cine
Authors: Kupferminc Margarita 
Published: April 2019

El sujeto nace inmerso en un grupo familiar, portador de creencias, ritos, normas; y también secretos y memorias ocultas. Son legados que viajan a través de las generaciones y encuentran diferentes y múltiples modos de manifestarse.
A partir de Freud y la teoría psicoanalítica, el sujeto es convocado a pensarse como sujeto de una herencia que hace un aporte a lo recibido transgeneracionalmente.
Se realiza una investigación bibliográfica sobre el tema. Se propone el uso del dispositivo cinematográfico para contribuir a la ampliación de la escucha y comprensión del analista en el trabajo con el analizante para ayudarlo a reparar traumas.
El método empleado en el presente trabajo consiste en la realización de un recorte de la película “Un secreto” que evidencia lo que se quiere demostrar.
Se demuestra cómo la violencia social y situaciones silenciadas u ocultas, se transmiten aún sin palabras y pueden ser generadoras de traumas; pues hay un vínculo dialéctico entre la singularidad del sujeto y el legado cultural en el que adviene.
La Shoah, conocida como Holocausto, constituye el paradigma de horror supremo cometido por seres humanos a otros seres humanos. Sus consecuencias permiten pensar todas las formas que toma la violencia social.
Maritime and Other Key Transport Issues for the Future – Education and Training in the Context of Lifelong Learning
Authors: Edler Jeannette , Infante Virginia 
Published: April 2019

The entire transport system will transform into an integrated transport system in response to future trends and demands. The EU Skilful project defines the impact on job profiles across all transport modes and at all levels of work and duties. Changing and emerging job profiles require training which on the one hand makes use of the latest training and education methods, while on the other meeting the need for the acquisition of special competencies, skills and abilities. The demand for individualization of training contents will soar in the interlinked global world and integrated transport systems.
An additional questionnaire was conducted in the spring of 2018, in the assessment of the maritime and transport sectors. The answers of course lecturers and organisers concerning present and future needs and lifelong learning issues were instructive, with most of the people having concrete ideas about lifelong learning.
Courses will therefore include future oriented contents, a practicable registration procedure with information for qualified trainers capable of tailoring course contents to the specific focus of the course and participants’ requirements, giving excellent lectures with relevant learning material and real usable factors, clear structure, practical parts, remarks of concrete relevance, communication parts for improving soft skills, experience exchange and learning from other participants, intercultural aspects for globalization, reconciling mixed group needs and requirements and learning to learn methods, using different adult suitable methods and finally focusing on emotions to capitalize on the motivation to learn.
Lifelong learning is a key issue for successful employers and employees.

Authors: Joshi Aditi , Ray Suzanne L. 
Published: April 2019

Objective
The purpose of this study was to document the academic experiences of students with visual impairment in a doctor of chiropractic program.

Methods
Ten participants were recruited, including 3 students who are “legally blind,” 2 student notetakers, 3 faculty members who taught students with visual impairment, and 2 staff members from the Disability Services Office. For this qualitative study, the students were recruited through the Disability Services Office. The participants were audiotaped during approximately 1-hour interviews conducted in a semistructured manner within a private setting (a quiet office) on the campus during office hours. Thematic analysis was conducted using a deductive method for codes and an inductive method for themes.

Results
We identified facilitators and barriers to the education of students with visual impairment. Notable facilitators were planning for accessible educational materials, accessibility of workable space, and support systems, such as notetakers and close interaction with faculty. Notable barriers were attitudes of students with visual impairment toward their education, lack of personnel training, and lack of disability awareness in the campus community.

Conclusion
Meticulous planning of resources and communication are key to enriching academic experiences of students with visual impairment.
Towards an Integrative Psychological Model for Climate Change Mitigation Behavior among Managers in the Tourism Industry
Authors: Kinyanjui D. N. 
Published: April 2019

The aims of the current paper are to provide an extensive review of the theoretical and empirical evidence on which current climate change mitigation efforts are based and to advance a new model of the determinants of mitigation behavior. The study was based on the review of relevant literature. The model specifically demonstrates the interplay between human values, attitude, knowledge, emotions and social norms as determinants of broad and greater levels of mitigation behaviours. The model is complemented by adding age and sex as confounders. It indicates the possible interrelationships between these factors with their joint effects being emphasized.
The model addresses a concern that most business-level climate change policies ought to be integrative, but are unfortunately, not. Detailed knowledge of psychological determinants is useful for policy makers to provide favorable conditions in support of business level climate change mitigation measures and how it can be used to measure and compare the impacts of the determinants so as to generate more applicable mitigation measures in optimizing climate change policies now and in the future.

Published: April 2019

AbstractAn efficient one‐pot enzymatic synthesis of cardiac glycosides with varied sugar chain lengths (average yield >80%) was carried out through sequential glycosylation using a steroid glycosyltransferase UGT74AN3 from Catharanthus roseus and a cyclodextrin glycosyltransferase from Bacillus licheniformis. A series of cardiac glycosides were obtained and showed enhanced affinity and selectivity for inhibition of the α2 isoform of Na+/K+‐ATPase. These findings demonstrate the significant potential of the one‐pot biocatalytic approach in the synthesis of diverse cardiac glycosides as potentially safer cardiotonic agents.magnified image

Published: April 2019

AbstractA copper acetate‐mediated reaction of benzaldehydes with nitromethane to synthesis of 3‐nitroisoxazoles is reported. A variety of nitro‐aryl‐disubstituted isoxazole derivatives can be prepared in moderate to good yields with benign functional group tolerance. This protocol is successfully applied in gram‐scale reaction. Preliminary mechanistic studies reveal that the aldehyde provided one carbon atom for the isoxazole ring, and nitromethane provided two carbon atoms and one nitrogen atom for the isoxazole ring. In this protocol, the C−O−N unit in the final isoxazole ring is formed from the rearrangement of nitromethane.magnified image

Published: April 2019

AbstractA microwave‐induced metal dissolution strategy is developed for in situ synthesis of copper nanowires/ZnS (CuNWs/ZnS) hybrids with core–shell structure. The CuNWs are used as microwave antennas to create local “super‐hot” surfaces to further initiate ZnS crystallization with full coverage on CuNWs. With the help of S2−, the hot metal surface further results in the CuNWs dissolution with promoted Cu+ diffusion and incorporation into the ZnS lattice. With the narrowed bandgap of ZnS and the strongly coupled interface between CuNWs and ZnS created by microwaves, the as‐prepared hybrid composites exhibit an enhanced activity and stability in visible light for the photocatalytic H2 evolution. The corresponding H2 evolution rate reaches up to 10722 µmol h−1 g−1 with apparent quantum efficiency (AQE) of 69% under 420 nm LED irradiation, showing a remarkably high AQE among the noble‐metal free visible light‐driven photocatalysts and demonstrating a promising potential in practical applications to deal with the energy crisis.

Published: April 2019

AbstractSurface‐confined covalent coupling reactions of the linear compound 4‐(but‐3‐en‐1‐ynyl)‐4′‐ethynyl‐1,1′‐biphenyl (1), which contains one alkyne and one enyne group on opposing ends, have been investigated using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The reactions show a surface‐dependent chemoselectivity: on Au(111), compound 1 preferentially yields cyclotrimerization products, while on Cu(111), a selective coupling between the enyne and alkyne groups is observed. Linear, V‐shaped string formations combined with Y‐shaped bifurcation motifs result in a random reticulation on the entire surface. DFT calculations show that the C−H⋅⋅⋅πδ− transition state of the reaction between the deprotonated alkyne group and a nearby H‐donor of the alkene group plays a key role in the mechanism and high chemoselectivity. This study highlights a concept that opens new avenues to the surface‐confined synthesis of covalent carbon‐based sp–sp2 polymers.

Published: April 2019

AbstractSaccharides are ubiquitous biomolecules, but little is known about their interaction with, and assembly at, surfaces. By combining preparative mass spectrometry with scanning tunneling microscopy, we have been able to address the conformation and self‐assembly of the disaccharide sucrose on a Cu(100) surface with subunit‐level imaging. By employing a multistage modeling approach in combination with the experimental data, we can rationalize the conformation on the surface as well as the interactions between the sucrose molecules, thereby yielding models of the observed self‐assembled patterns on the surface.
Spatiotemporal Heterogeneity of Reactions in Solution Observed with High‐Speed Single‐Nanorod Rotational Sensing

Published: April 2019

AbstractA high‐speed darkfield microscope has been developed to monitor the rapid rotation of single gold nanorods (AuNRs) and used to study the spatiotemporal heterogeneity of chemical reactions in free solution. A wide range of viscosities from 237 cP to 0.8 cP could be detected conveniently. We studied H2O2 decomposition reactions that were catalyzed by AuNRs coated with Pt nanodots (AuNR@PtNDs) and observed two different rotational states. The two states and their transitions are related to the production and the amalgamation of O2 nanobubbles on the nanorod surface depending on H2O2 concentration. In addition, the local fluidic environment of pure water was found to be non‐uniform in time and space. This technique could be applied to study other chemical and biochemical reactions in solution.
One‐Dimensional Cuprous Selenide Nanostructures with Switchable Plasmonic and Super‐ionic Phase Attributes
Authors: Cho Ki‐Hyun , Heo Jaeyoung , Sung Yun‐Mo , Jain Prashant K. 
Published: April 2019

AbstractCuprous selenide nanocrystals have hallmark attributes, especially tunable localized surface plasmon resonances (LSPRs) and super‐ionic behavior. These attributes of cuprous selenide are now integrated with a one‐dimensional morphology. Essentially, Cu2Se nanowires (NWs) of micrometer‐scale lengths and about 10 nm diameter are prepared. The NWs exhibit a super‐ionic phase that is stable at temperatures lower than in the bulk, owing to compressive lattice strain along the radial dimension of the NWs. The NWs can be switched between oxidized and reduced forms, which have contrasting phase transition and LSPR characteristics. This work thus makes available switchable, one‐dimensional waveguides and ion‐conducting channels.

AbstractUronic acids are important constituents of polysaccharides found on the cell membranes of different organisms. To prepare uronic‐acid‐containing oligosaccharides, uronic acid 6,3‐lactones can be employed as they display a fixed conformation and a unique reactivity and stereoselectivity. Herein, we report a highly β‐selective and efficient mannosyl donor based on C‐4 acetyl mannuronic acid 6,3‐lactone donors. The mechanism of glycosylation is established using a combination of techniques, including infrared ion spectroscopy combined with quantum‐chemical calculations and variable‐temperature nuclear magnetic resonance (VT NMR) spectroscopy. The role of these intermediates in glycosylation is assayed by varying the activation protocol and acceptor nucleophilicity. The observed trends are analogous to the well‐studied 4,6‐benzylidene glycosides and may be used to guide the development of next‐generation stereoselective glycosyl donors.
Reassignments and Corroborations of Oxo‐Bridged Natural Products Directed by OSE and DU8+ NMR Computation
Authors: Kutateladze Andrei G. , Krenske Elizabeth H. , Williams Craig M. 
Published: April 2019

AbstractStructural misassignments of natural products are prevalent in the literature. Developing methods and theoretical concepts to assist those undertaking structural elucidation is therefore of paramount importance, such that biologists and synthetic chemists avoid pursuing phantom chemical entities. Herein described is a strategy for predicting the isolabilities of oxygen‐substituted bridgehead natural products based on calculations of olefin strain energies, NMR chemical shifts and coupling constants (DU8+). This approach provides corroborating evidence for the structures of certain bridgehead alkene natural products while leading to the reassignment of several other structures.
[Fe(H2O)5(NO)]2+, the “Brown‐Ring” Chromophore
Authors: Monsch Georg , Klüfers Peter 
Published: April 2019

AbstractAlthough the “brown‐ring” ion, [Fe(H2O)5(NO)]2+ (1), has been a research target for more than a century, this poorly stable species had never been isolated. We now report on the synthesis of crystals of a salt of 1 which allowed us to tackle the unique bonding situation on an experimental basis. As a result of the bonding analysis, two stretched, spin‐polarised π‐interactions provide the Fe–NO binding—and challenge the concept of “oxidation state”.
Rhodium(I)‐Catalyzed Enantioselective Cyclization of Enynes by Intramolecular Cleavage of the Rh−C Bond by a Tethered Hydroxy Group

Published: April 2019

AbstractRhodium(I)‐catalyzed enantioselective intramolecular cyclization of enynes having a hydroxy group in the tether was investigated, and various cyclic compounds possessing a chiral quaternary carbon center were obtained in high yields with high ees. In this cyclization, a Rh−C(sp2) bond in the rhodacyclopentene intermediate, which was formed by enantioselective oxidative cycloaddition of enynes to a chiral rhodium(I) complex, was intramolecularly cleaved by σ‐bond metathesis of a tethered O−H bond in the substrate. Furthermore, it was found that the cyclic compounds were obtained with high ees even when the starting materials having a racemic secondary alcohol moiety were used in this reaction.
Fishers' experiences and perceptions of marine mammals in the South China Sea: Insights for improving community‐based conservation
Authors: Liu Mingming , Lin Mingli , Turvey Samuel T. , Li Songhai 
Published: April 2019

Abstract

The successful conservation of marine mammals is often dependent upon support from local fishing communities, and valuable conservation insights can be obtained through understanding fishers’ attitudes and awareness of marine mammals.
A new local ecological knowledge dataset was obtained through large‐scale questionnaire‐based interviews with 510 artisanal fishers from 16 coastal fishing communities around Hainan, China. Almost all respondents (92.7%) reported regular encounters with marine mammals. Many respondents reported negative interactions with marine mammals, including bycatch (25.5%), consumption (36.1%), and the sale of meat (9.2%), and respondent perceptions of marine mammals were often negative.
Generalized linear models (GLMs) indicated that respondent experiences of marine mammal encounters and bycatch events were mainly predicted by indices of fishing effort and experience, rather than by geographic or socio‐economic factors. Respondent experiences of eating or selling marine mammal meat were predicted by geographic location and by some livelihood and socio‐economic factors. Respondent perceptions of marine mammals were instead predicted by fishing experience and education level.
Classification and regression trees (CARTs) showed that the most important factors determining respondent experiences and perceptions were number of fishing years and educational level, respectively. Both GLMs and CARTs indicated the complex effects of geographic, livelihood, and socio‐economic factors on respondent experiences and perceptions of marine mammals.
Regional community‐based conservation of marine mammals could be promoted through improved regulatory management and environmental education, sustainable ecological exploitation and economic development, and positive partnerships and collaboration between fishing communities, enforcement agencies, and researchers.
