Effect of spacer layer on flux-pinning properties of iron-based superconductors
Authors: Di Gioacchino Daniele , Poccia Nicola , Marcelli Augusto , Puri Alessandro , Xu Zhu-an , Cheng Jie , Chu Wangsheng , Saini Naurang Lal
Published: December 2016

We investigated the magnetic flux-pinning in iron-based 1111-type (REFeAsO, RE= rare earth) and 11- type (FeSe1−xTex) superconductors by third harmonic acmagnetic susceptibility measurements, a technique sensitive to the dynamics of magnetization, probing non-linear processes in flux pinning transport. Despite the larger thermal fluctuations due to the high critical temperature and large anisotropy, flux dynamics of 1111-type pnictides points out a more efficient pinning mechanism than the one in the 11-type chalcogenides. We have associated the stronger pinning in the 1111-family to the presence of REO (RE=rare earth) spacer layers separating the active FeAslayers unlike the 11-chalcogenides in which no spacer layers are present. Therefore, the disorder in the FeAs layers induced by the misfit strain due to spacer layers has an important role in the enhanced flux pinning of 1111-type superconductors.

As múltiplas alfabetizações midiáticas
Authors: Meyrowitz Joshua
Published: December 2016

Existem pelo menos três tipos de alfabetizações midiáticas, cada uma delas ligada a uma diferente concepção do que nós pretendemos dizer com o termo mídia. A noção de que os mídia são condutores que transmitem mensagens aponta para a necessidade da alfabetização no conteúdo dos mídia. A idéia de que os mídia são diferentes linguagens sugere a necessidade de alfabetização numa gramática midiática, isto é, entender o significado das variáveis de produção dentro de cada meio. A concepção dos mídia como ambientes sugere a necessidade de se perceber a influência das características relativamente fixas de cada meio (alfabetização midiática), tanto nas comunicações individuais como nos processos sociais em geral. A alfabetização mediática, em particular, oferece algumas idéias especiais no que se refere as origens, problemas, e possibilidades de um movimento pela alfabetização midiática.

Quem ri por último ri melhor? Uma análise do humor na hipermodernidade a partir do programa “Custe o que Custar”
Authors: Acselrad Marcio , Facó Katiuska Macedo
Published: December 2016

Estudiosos do humor e do riso como Lipovetsky (2004) e Minois (2003) afirmam que o riso moderno, ligado ao pensamento iluminista, apresentava-se como esclarecedor e crítico levando as pessoas a refletirem e a buscarem mudar o mundo em que viviam. Por outro lado, o riso atual, capturado pelos meios de comunicação de massa e pela publicidade, apresenta-se como vazio de significado, descompromissado, objetivando somente ser lúdico e estimular o consumo. Até que ponto é possível corroborar com tais opiniões? Não seriam apressadas essas conclusões sobre o humor dos meios de comunicação? Será que na atualidade não somos capazes de produzir um humor com pretensões além do divertimento? Partindo da análise do programa de televisão “Custe o que custar”, o CQC, exibido pela Rede Bandeirantes de Televisão, a Band, e através da realização de um trabalho de pesquisa com grupo focal, pretendemos investigar até que ponto estas hipóteses são ou não comprováveis.

Published: December 2016

Este artigo faz parte da pesquisa “Comunicação, consumo e novas subjetividades: um estudo sobre as práticas mediáticas na sociedade”, financiada pela FAPESP. Nele, analisamos a sociedade da comunicação e da cultura de consumo, que se difunde nas sociedades do final do século XX e início do XXI, buscando compreender as transformações que têm ocorrido em sua esfera e o modo como incide nas subjetividades contemporâneas. Para tanto nos detemos no campo da publicidade e do marketing. Do ponto de vista do campo publicitário e dos anúncios, nota-se uma mudança de valores onde o empreendimento voltado para a “construção da marca” objetiva criar uma boa imagem da empresa. Do ponto de vista do marketing, busca-se estabelecer uma relação emocional com o consumidor, objetivando satisfações intangíveis, que produzem reações sensoriais. **************************************************** ABSTRACT This essay is part of the research “Communication, consumption and new subjectivities: a study of media practices in society”, financed by FAPESP. It focuses on the communication society and consumer culture, which is spreading on the societies in the late twentieth century and the beginning of the century. We are seeking to understand the changes that have occurred in this societies and how it reverberates on contemporary subjectivities. For that we’ve focused on advertising and marketing. From the view of the advertising, there is a change of values where the “branding” aims to create a good image of the company.

El patrimonio cultural histórico arquitectónico costarricense: una deuda constitucional
Authors: Muñoz Muñoz Marcela
Published: December 2016

ResumenLa formulación del artículo 89 de la Constitución Política de Costa Rica se basa en un Estado Social, no Cultural, de Derecho. La cultura se refiere como un fin de la política y no como un bien jurídico, objeto de tutela, lo cual parece restarle importancia a los intereses jurídicos. En esta línea, la norma constitucional refleja la ausencia de un núcleo conceptual mínimo en torno al patrimonio, cuya tutela resulta, entonces, difusa. Dicha omisión –que conlleva la reducción de un valor histórico arquitectónico a uno artístico— limita tanto el interés cultural, en general, como el arquitectónico, en específico. Con el fin de facilitar la comprensión del (oscuro) régimen tutelar existente, dispuesto en la Ley de Patrimonio Histórico Arquitectónico Nº7555 (1995) y su Reglamento (2005), el artículo revisa el concepto jurídico de patrimonio en dos direcciones: primero, la constitucionalización de los bienes culturales patrimoniales (sección A); segundo, la objetivación de lo cultural en general, y de lo histórico arquitectónico en particular, a la luz del interés jurídico (sección B). Dicho examen permite delinear un concepto integrador del patrimonio cultural y dentro de este, del histórico arquitectónico; lo cual, en última instancia, podría favorecer su tutela. AbstractThe Article 89 of the Politic Constitution of Costa Rica is based on a Social State, not a Cultural State of Law. Culture refers to as a political and not a legal right, subject to protection, which seems to belittle the legal interests. In this line, the constitutional provision reflects the absence of a minimum conceptual core around heritage, whose protection is then diffused. This omission involves the reduction of an architectural historical value to an artistic one, limiting cultural interest in general and the architectural, specifically. In order to facilitate understanding of the (dark) regime tutelary existing provisions of the Law of Historical Heritage Architectural Nº7555 (1995) and Regulations (2005), the article reviews the legal concept of heritage in two directions: first, the constitutionalization of heritage cultural property (section A); second, the objectification of culture in general, and the historical architecture in particular, in the light of legal interest (section B). This examination allows delineate an integrative concept of cultural heritage and within this, the architectural history; which ultimately could favor their protection.

New politics of governing global capitalism: Sovereign governments and living law
Authors: Islamoglu Huri
Published: December 2016

Since the crisis of 2007–2009, sovereignty, government and politics are on the agenda of social sciences and of international policy platforms, most recently in Davos. This is a departure from anti-statist, free-tradist visions of global market development in the 1980s and 1990s when sovereignty was simply associated with freedom of action of economic actors (most significantly, global corporations and banks) and governance simply referred to technical rules serving the ends of these actors posed in terms of dictates of the market. This paper points to societal dislocations (e.g. income discrepancies, unemployment) incumbent on global market development and to a time lag in which these made themselves felt in the developed and developing world. It argues that the developing world experienced the disillusionment with markets in the latter part of 1990s and early 2000s and sought solutions in effective governments, putting them in the service of reaping the benefits of global market expansion for individual regions. It meant non-liberal ways of governing markets, distancing from abstract formulations of individual rights, turning the ‘rule of law’ into living law deeply rooted in societal concerns not limited to commercial actors but including those of both blue-collar and white collar workers, of migrant populations, and women. At issue is an introduction of politics, of political agency and initiatives. The developed world rejected what is labeled as an ‘autocratic turn’; and is lost for a solution to market woes, except for further measures to maximize gains by major commercial actors, as in the case of the Greek crisis.

Published: December 2016

Background: The lesion of skin of the majority atopic dermatitis patients is chronically colonized by bacteria belonging to the species Staphylococcus aureus. Topical antibacterial and anti-inflammatory therapy treatment are often ineffective due to fast recolonization by S. aureus and exacerbation of allergic process.Aims: Our aim was to determine a frequency of S. aureus colonization in skin lesions, mucous membranes of the nasal cavity and intestine of children with atopic dermatitis, to compare the genotypes of Staphylococcus aureus strains isolated from different biotopes of atopic dermatitis patients, and to clarify whether the intestinal and nasal cavities microbiota may act as a source of S. aureus recolonization of skin lesions.Materials and methods: Bacteriological examination of fecal samples, skin, and nasal swabs was conducted in 38 atopic dermatitis patients. The pure bacterial cultures of S. aureus were identified using API Staph (Biomerieux, France) and Vitek 2 MS (Biomerieux, France). Isolates of S. aureus were subjected to genotyping by analysis of rRNA internal 16S-23S rRNA spacer regions and high resolution melting analysis (HMR) of polymorphic spa X-regions.Results: 99% S. aureus strains were successfully identified using MALDI-TOF mass-spectrometry. S. aureus cultures were isolated from all biotopes in 31,6% of children, from skin and nasal cavities — in 42% of cases, from skin and feces — in 2,6% of cases, only from skin — in 10,5%, from nasal cavities and feces — in 2,6%, and only from nasal cavities — in 2,6% of cases. In 8% of children, S. aureus was not detected in any of the biotopes. Genotyping of the isolates enabled the detection of 17 different genotypes. A match between the genotypes of skin and nasal strains, and skin and fecal strains was observed in 88% and 61% of the cases respectively.Conclusions: The observed a high-frequency matching genotypes suggests the possibility of migration of S. aureus strains inside biotopes in humans and the absence of specialization to colonization of any of the niches.
Numerical modelling of thermo-active piles in London Clay
Authors: Gawecka Klementyna A. , Taborda David M. G. , Potts David M. , Cui Wenjie , Zdravković Lidija , Haji Kasri Muhamad S.
Published: December 2016

Thermo-active foundations utilise heat energy stored in the ground to provide a reliable and effective means of space heating and cooling. Previous studies have shown that the effects of temperature changes on their response are highly dependent on their interaction with the surrounding ground. Consequently, it is necessary to consider this interaction and include both the thermal and mechanical behaviour of the ground in design. This paper addresses this issue by performing state-of-the-art finite-element analyses using the Imperial College Finite Element Program, which is capable of simulating the fully coupled thermo-hydro-mechanical behaviour of porous materials. First, the Lambeth College pile test is analysed to demonstrate the capability of the adopted modelling approach to capture the observed response under thermo-mechanical loading. Subsequently, a detailed study is carried out, demonstrating the impact of capturing the fully coupled thermo-hydro-mechanical response of the ground, the use of appropriate boundary conditions and the uncertainty surrounding thermal ground properties. It is demonstrated that the modelling approach has a large impact on the computed results, and therefore potentially on the design of thermo-active piles. Conversely, the effects of thermal conductivity and permeability of the soil are shown not to influence the pile behaviour significantly.
Negative skin friction pile concepts with soil–structure interaction
Authors: Tan Siew Ann , Fellenius Bengt H.
Published: December 2016

Code-based design of piles with negative skin friction (NSF) considers the NSF force (the drag force) as a load to be imposed on the pile as an unfavourable design action. These codes – for example Singapore Code of Practice CP4, UK Standard BS EN 8004:1986 and the recent Eurocode 7 (EC7) (BS EN 1997-1:2004) – would indirectly factor up the value of the drag force while at the same time disregard the shaft resistance above the neutral plane and factor down the positive shaft resistance below the neutral plane. Thus, the pile design in very deep soft clays typical of Singapore and Asian coastal plains will lead to very conservative pile lengths to meet the code requirements. The Fellenius unified pile design method recognised this deficiency, and it allows for better pile design with NSF taking into account the need for both force and settlement equilibrium between the pile and the soil. Fortunately, EC7 also allows for interactive pile–soil analysis using modern finite-element method tools that can optimise pile design for NSF, in particular when the remaining consolidation settlements around the piles are relatively small. This paper will compare these methods, provide insights into the proper understanding of NSF effects on pile behaviour and recommend the way forward for rational and economical pile design in settling soils.

Los mayas de los Altos de Chiapas y sus vecinos occidentales: interacción, identidad e intercambio en una frontera cultural
Authors: Paris Elizabeth H. , López Bravo Roberto
Published: December 2016

El presente estudio investiga las formas multifacéticas en que los límites políticos y las barreras sociales fueron definidas y mantenidas en la frontera occidental de la región lingüística y cultural maya. Las comparaciones del intercambio de diferentes bienes y medios pueden resaltar el grado en el que las barreras culturales fueron permeables o impenetrables en la zona fronteriza entre los mayahablantes de tzotzil de los Altos de Chiapas y sus vecinos hablantes de zoque de la Depresión Central. Las relaciones de intercambio entre ellos parecen haber sido suspendidas al final del período Postclásico Temprano, sugiriendo que la permeabilidad de la frontera occidental decreció a lo largo del tiempo, posiblemente como resultado de la llegada y expansión de los chiapanecas a la Depresión Central. Sin embargo, algunos tipos de artefactos de alto valor, como los ornamentos de metal, continuaron siendo intercambiados en esta frontera cultural.

Published: December 2016

I descend from the tides that crash and break against my ancestral mountain named Mauao. I am of the running currents that give life to our people. The island of Matakana is where I plant my feet and call home. Tauranga's sea, and Tauranga's people, are one. I am fortunate enough to spend a lot of my time doing what I am passionate about. I get to work with many different parts of the education system and with many wonderful communities by sharing my skills and culture, through workshops and guest speaking. I also get to share these same things by being invited to perform at many events, festivals and gigs where I perform poetry strongly rooted in a Māori-centric world view. I guess the aim of most poets is to publish a book. Personally, my goal is to make poetry, speaking well and oral traditions cool, so it will be appealing for young people to use.

Trigonometric Cubic B-spline Collocation Method for Solitons of the Klein-Gordon Equation
Authors: Korkmaz Alper , Ersoy Ozlem , Dag Idiris
Published: December 2016

In the present study, we derive a new B-spline technique namely trigonometric B-spline collocation algorithm to solve some initial boundary value problems for the nonlinear Klein-Gordon equation. In order to carry out the time integration with Crank-Nicolson implicit method, the order of the equation is reduced to give a coupled system of nonlinear partial differential equations. The collocation approximation based on trigonometric cubic B-splines for spatial discretization is followed by the linearization of the nonlinear term. The efficiency and accuracy of the present method are validated by measuring the error between the numerical and analytical solutions when exist. The conservation laws representing momentum and energy are also computed for all problems.

Published: December 2016

Wstęp: Choroby sercowo‑naczyniowe są zaliczane do chorób cywilizacyjnych i stanowią duży problem społeczny, ponieważ są główną przyczyną zgonów. Według danych Światowej Organizacji Zdrowia (World Health Organization – WHO), co roku z powodu chorób układu krążenia w krajach wysoko rozwiniętych umiera ponad 17,3 mln osób. W Unii Europejskiej liczba zgonów wynosi ponad 2 mln i stanowi 42% ogólnej umieralności. Celem pracy była analiza wybranych czynników ryzyka chorób sercowo‑naczyniowych u pacjentów zakwalifikowanych do chirurgicznej rewaskularyzacji serca oraz zarys ich profilu społecznego.Materiał i metody: Badania zostały przeprowadzone wśród pacjentów zakwalifikowanych do operacji w Klinice Kardio‑ chirurgii Samodzielnego Publicznego Szpitala Klinicznego nr 2 Pomorskiego Uniwersytetu Medycznego w Szczecinie (SPSK‑2 PUM). Wzięło w nich udział 90 pacjentów. Badania zostały przeprowadzone metodą sondażu diagnostycznego z wykorzystaniem autorskiej ankiety oraz danych uzyskanych z dokumentacji medycznej.Wyniki: Ocenie poddano wybrane modyfikowalne czynniki ryzyka chorób układu sercowo‑naczyniowego. W badanej gru‑ pie aktualnie palących było 15 (17%) osób. Najwięcej, 38 (42%) pacjentów nie paliło papierosów dłużej niż 2 lata. Na cukrzycę choruje 33 (37%) pacjentów. Ponad połowa – 47 (52%) badanych wskazała, że odżywia się nieracjonalnie. Większość pacjentów była otyła 37 (41%), w tym chorujących na cukrzycę – 18 i nie‑ chorujących – 19. Na nadciśnienie chorowało 58 (64%) pacjentów.Wniosek: Potwierdzonymi w badaniach czynnikami predys‑ ponującymi do choroby wieńcowej były: cukrzyca, otyłość oraz palenie papierosów. Prewencja cukrzycy, zaprzestanie palenia tytoniu, zmiana stylu życia powinny być głównymi działaniami edukacyjnymi w praktyce lekarza rodzinnego w celu zapobiegania chorobom układu sercowo‑naczyniowego, zwłaszcza wśród osób starszych.

Wysoki poziom dyscypliny sprawia, że coraz młodsi zawodnicy trenują w liczbie godzin wykraczającej poza normy uznane za bezpieczne dla młodego, wzrastającego organizmu. Celem pracy była ocena rozwoju biologicznego dziewczynek uprawiających łyżwiarstwo figurowe na podstawie analizy danych uzyskanych z pomiarów zawodniczek polskich klubów sportowych. Porównano także przebieg rozwoju młodych łyżwiarek do ich sióstr nieuprawiających tej dyscypliny sportu.Materiał i metody: Zebrano 181 pomiarów dziewcząt z 3 klubów łyżwiarskich oraz przeprowadzono ankiety wśród ich rodziców na temat rodzeństwa łyżwiarek.Wyniki: Zawodniczki są stosunkowo niższe i lżejsze od swoich rówieśniczek, jednak różnica ta nie jest istotna statystycznie. Odnotowano natomiast znaczne rozbieżności między dziewczynkami a ich siostrami, które nie trenowały żadnej dyscypliny sportowej.Wnioski: Wyniki pozwoliły również wnioskować o wpływie czynników genetycznych oraz selekcji na morfologię zawodniczek łyżwiarstwa figurowego.

Wstęp: Od początków XX w. notuje się stały wzrost emisji fluorków (F−) do środowiska, przede wszystkim na skutek rozwoju przemysłu, fluorkowania wody pitnej i powszechnego stosowania past do zębów wzbogaconych we fluorki. Wszystko to przyczynia się do intensywniejszego nagromadzania tych substancji w organizmach kręgowców, głównie w utworach kostnych. W związku z tym uzasadnione jest kontrolowanie stężeń F− u ludzi i innych długowiecznych ssaków. Dla celów ekotoksykologicznych od dawna trwają poszukiwania gatunków ssaków, które mogą służyć jako dobre bioindykatory zanieczyszczenia środowiska F−. W przeciwieństwie do ssaków kopytnych, długowieczne udomowione i dziko żyjące ssaki drapieżne (w tym pies, lis i jenot) rzadko są wykorzystywane w bioindykacji zanieczyszczenia środowiska F−. Głównymi celami pracy było: 1) poznanie stężeń F− w kościach uzyskanych od człowieka, psa, lisa i jenota pochodzących z północno‑zachodniej Polski; 2) dokonanie porównań wewnątrz‑ i międzygatunkowych wartości stężenia F− w próbkach kostnych badanych ssaków na tle warunków bytowo‑środowiskowych; 3) zbadanie związków między stężeniami F− w kościach a wiekiem lub kategorią wiekową analizowanych ssaków.Materiał i metody: Materiał do badań stanowiły kości współ- tworzące staw biodrowy, pochodzące od 36 pacjentów po alloplastyce stawu biodrowego, 43 psów ze szczecińskich lecznic oraz 32 lisów i 18 jenotów dostarczonych przez myśliwych. Całość materiału badawczego obejmowała 129 próbek, a oznaczenia F− (metodą potencjometryczną z wykorzystaniem jonoselektywnej elektrody Thermo Orion) wykonano w 3 powtórzeniach. Stężenie F− wyrażono w przeliczeniu na suchą masę.Wyniki: Analiza międzygatunkowa wykazała, że najwięcej różnic w stężeniu F− w materiale kostnym odnotowano między lisem i jenotem, a następnie między psem i lisem oraz psem i dzikimi psowatymi (lis i jenot łącznie). Bliskie istotności statystycznej różnice w koncentracji F− zaznaczyły się mię- dzy próbkami kostnymi człowieka i lisa oraz człowieka i psa. W przypadku człowieka i jenota, człowieka i poszczególnych gatunków psowatych (pies, lis, jenot łącznie) oraz psa i jenota nie odnotowano istotnych statystycznie różnic w stężeniu F− w ich kościach. Wnioski: Stwierdzono, że udomowione i dziko żyjące psowate są dobrymi bioindykatorami zanieczyszczenia środowiska fluorkami, bowiem odzwierciedlają one koncentrację fluorków w kościach obserwowaną u człowieka żyjącego na podobnym obszarze.

The thickness of super heavy oil reservoir in Liaohe oilfield reaches 150 meters, and the practice of using Steam-assisted gravity drainage (SAGD) to develop very thick reservoir has made great achievements. In order to further increase the oil recovery rate and the ultimate recovery factor, and make the oilfield development more efficient, the drilling and completion techniques of 95/8" production screen liner have been proposed and applied for the first time at home. Contrast with the conventional 7" production screen liner, the flow area of 95/8" production screen liner increases by 58 percent, and the oil recovery rate increases by 3 percent. The application of big bore horizontal well has successfully solved a variety of technique challenges, such as the design of flow passage and the optimization of strength designing of 95/8" screen liner, the rigidity analysis and mechanical calculation of large size casing, the well trajectory control by reaming-after-boring method in big bore well, the big borehole cleaning by the MMH drilling fluid and polysulfonate drilling fluid, the safe and smooth casing running of the completion pipe string by pseudo-catenary trajectory and rotary guide shoe, segregated completion in horizontal well by external casing packer assisted by high temperature, and so on. The big bore well techniques have been successfully used in three well, and single well has produced 147 tons per day. The daily production of big bore well is three times as many as the conventional well. The practice shows that the application prospect of drilling and completion techniques of big bore horizontal well in SAGD for the development of super heavy oil is bright.
Fluidic Diode Autonomous Inflow Control Device for Heavy Oil Application

In heavy oil fields, well longevity is limited by water inflow. Passive inflow control devices (ICDs) are effective in terms of balancing production flow and delaying the onset of water production. Nevertheless, when gas and/or water breakthrough occurs, a passive ICD enables production of the unwanted fluid. Autonomous ICDs can provide additional restriction to the unwanted fluids and can further enhance the production of oil.

The fluidic diode autonomous ICD is functionally based on fluid dynamics technology in which internal geometry directs flow movement based on the viscosity of the fluid. The autonomous ICD enhances oil production while restricting water and gas influx, without the requirement of intervention or moving parts within the device. The result is improved sweep efficiency, which can extend well life and thereby assist in reducing operating costs. Effective design of an autonomous ICD completion is aided with an accurate prediction of the flow behavior through the device. This paper describes flow testing and field performance of a fluidic diode autonomous ICD optimized for the production of very heavy oils with a viscosity above 150 centipoise (cp), while restricting water and gas production.

The test results of the autonomous ICD demonstrate that the fluidic diode can produce more oil while restricting water. In fact, heavy oil can flow at a higher rate with less pressure drop than water. Flow performance of this device has been characterized by measuring the pressure drop versus the flow rate at differing viscosities, confirming that the autonomous ICD effectively restricts undesired fluids, while enhancing the production of oil. Numerical simulations demonstrate an improvement of water reduction by more than 50% compared to standalone screen completions. This technology has been used to promote oil production and restrict water influx in fields where the oil viscosity is greater than 700 cp. This paper also demonstrates the appropriate design philosophy when determining the suitable application of the technology to help maximize oil recovery and minimize water production.

Fluid flow performance is what truly distinguishes the autonomous ICD from other devices. This fluidic diode autonomous ICD is a robust, reliable solution with no moving parts, nor the requirement of intervention of any kind. Its predictable flow performance has been proven through testing, modeling, and field application.

World class oil and gas operating companies apply supply chain management to minimize the risks of investment costs overrun, delays and future higher operating costs of field development projects. Supply chain is a cross-functional approach to plan the flow of goods and services required by a project, based on its front end loading (FEL) specifications, in order to meet business objectives with a successful execution and total satisfaction of the final customers. This paper presents lessons learnt from modeling the supply chain of a steam-based thermal enhanced oil recovery (EOR) heavy oil field development project in Kuwait.

A critical building block of a supply chain model is the supply-demand matrix, which is prepared using information about the needs of the steam-based thermal EOR assets (natural and physical) and identification of requirements organized in segments, around capital, technology or manpower categories. A preliminary identification was made about local capabilities to meet these requirements.

A work breakdown structure from the front-end engineering design was used to generate a supply-demand matrix with materials including special needs such as energy, water and logistics. The model allows the identification of critical requirements and the information to design alternate options to reduce the risk of lack of supply. One practical result is a map with all required suppliers classified according to the type of goods or services, and the specifications or scope of work for selecting a contracting strategy.

Supply chain modeling provides a best practice to meet the demand of goods and services of complex heavy oil steam-based thermal enhanced oil recovery projects. It would help to guide the process of building capabilities in Kuwait oil industry for this type of recovery technologies, which will play a critical role in long-term business strategy.
Experimental Study for Enhancing Heavy Oil Recovery by Nanofluid Followed by Steam Flooding NFSF

With the increasing global demand for energy, great attention has been focused on utilizing heavy oil and bitumen, which cannot be easily recovered. This has been achieved by reservoir heating using conventional methods such as steam. However, these approaches are often accompanied by high energy consumption, large amounts of wastewater generation, and undesirable environmental damage. Recently, nanoparticles have become an attractive agent for enhancing oil recovery (EOR) in the laboratory scale. In addition, nanotechnology was chosen as an alternative method to unlock the remaining oil resources during the last decade. Consequently, this research provides one of the promising techniques for in-situ heavy oil recovery using metal-based nanoparticles to maintain in-situ heat generated by steam. Several core flood experiments were conducted to compare the recovery of Kuwaiti heavy oil using; hot water, superheated steam (SH), nanofluids, and combination of nanofluids and SH team.

Initially, the individual hydrophilic nanoparticles (HFNPs) including; zirconium dioxide (ZrO2), titanium dioxide (TiO2), zinc oxide (ZnO), and iron oxide (alpha) (Fe2O3-α), of average particle size (APS) of 20–50 nm and different thermal conductivities, were dissolved in formation water to create stable nanofluids. The results of the nanofluids coreflooding showed that ZrO2 provides higher oil recovery than TiO2, Fe2O3-α, or ZnO. However, the combination of ZrO2 (low thermal conductivity) at a concentration of 0.05 wt% with SH at 1 PV exhibits highest oil recovery near 46.9%, followed by combination of ZnO (high thermal conductivity) at same concentration with SH which had a recovery of 42.7%, then followed by SH steam of 35% recovery. This indicates the ability of HFNP with low APS and low thermal conductivity of providing promising EOR results when combined with low steam consumption and low produced water.
