Anti-Neu5Gc Antibody Kit Protocol - ELISA v2
Authors: Miller Kelsey
Published: May 2017

This protocol is essentially the same as a standard ELISA protocol, with one major exception – all animal compounds must be avoided in buffers, etc. because they contain Neu5Gc, which will interfere with antibody activity and result in misleading data. Essentially, the glycoconjugate to be evaluated is immobilized on an ELISA plate and exposed to a primary antibody. The antibody provided in this kit has been shown to identify as little as 5 pmol of Neu5Gc per microgram glycoprotein, which is at or below the current detection limit for conventional DMB HPLC analysis. An advantage of the ELISA procedure is that it confirms the presence of Neu5Gc on the glycoconjugate of interest, but use caution, as it also reacts with solution/media that contains glycoconjugate.
Imperial Imagination in Cymbeline
Authors: Zhang Fangfang
Published: May 2017

Though telling the story of the Roman conquest, Cymbeline features alliance and fraternity, instead of enmity, between ancient Briton and the Roman Empire. Cymbeline, through its appropriation of the Roman-Briton tie, gives shape to the imperial imagination of the Stuart court. Shakespeare depicts the historical King of Briton, Cymbeline, the legendary warrior raised by the Romans, as the British counterpart of Caesar Augustus and heir of the mythical Brutus. Cymbeline can also be seen as an avatar of James I, who at that time willed to become the second Brutus and was keen to conquer. Shakespeare presents a Romanized Briton as the proper heir to the Roman Empire, degrading the Empire’s natural descendent Italy for their moral corruption. The sense of moral superiority caters to the burgeoning imperial practice of the Jacobean monarch.

By studying such items as affecting factors, development history, implementing strategies of Australian language education policy under the background of multiculturalism, researchers can get a clue of the law of development of the language education policy in the developed countries and even the world. To be specific, through studying the development history of Australian language education policy under the background of multiculturalism, the paper puts forward some enlightenment and presents some advice on the China’s foreign language education.
The Evolution of Concept of Popular Culture and Its Significance
Authors: Deng Wensheng , Deng Pengzhuo
Published: May 2017

The paper has checked the evolution of concept of popular culture, which presents the essential meanings and its hidden reasons to general readers. Built upon the conceptual evolution, i.e. roughly from British School, Frankfurt School until French School, the thesis explores the possible characteristics of today’s popular culture of China in the ever-changing era. First, subjectivity of the people, i.e. the subject of China’s popular culture is composed of average people; Second, aesthetic experience, i.e. China’s popular culture is committed to perfecting her subjects’ mind and moral sense by providing beautiful contents, but not ugly immoral ones as currently appeared on new media; Third, “cultural consciousness,” i.e. the subjects should have confidence, reflection upon China’s popular culture, and not reject “others” blindly.
Chronic cervicitis: role of adult autologus stem cells
Authors: Jain Mayank , Jain Sapna
Published: May 2017

Background: Stem cells are biological cells found in all multi-cellular organisms and capable to differentiate into diverse specialized cell types and self-renew to produce more stem cells. Stem cells act as immuno-modulatory, angiogenetic, cell repairing and cell protecting agents. They also have strong anti-inflammatory effect due to paracrine action of trophic factors release. Chronic cervicitis is very common disease of adult women worldwide, chronic infection and inflammation of the cervix is hard to cure with high recurrence rate leading to long term consequences like pelvic inflammatory disease, infertility, ectopic pregnancy, chronic pelvic pain, increased predisposition to HPV and HIV infection and even can be a precursor of cervical cancer.Methods: To show the therapeutic and symptomatic benefits of these cells in chronic cervicitis we injected 10 patients with adult autologus stem cells (AASCs) locally in the cervix, and PRP, growth factors IV. All the cells were harvested from bone marrow after bone marrow aspiration.Results: Clinical benefits were evident on follow up visits in the entire treated patient. All the patient had shown improvement in symptoms like continuous malodourous discharge, dyspariunea, pelvic pain and pressure, backache, itching and burning, post coital bleeding.Conclusions: Present study have shown that AASCs and growth factors is a safe effective ethical and viable option not only to cure the disease but also in improving the quality of life of a woman and protecting her from its significant consequences.

Resumo: A mesa redonda intitulada “MESTRES EM CANTARIA: tecnologia e prática” pretendeu trazer para o 1º Simpósio Brasileiro de Caracterização e Conservação da Pedra uma discussão sobre a situação atual da profissão de Mestres Canteiros, a partir dos recentes trabalhos de conservação e restauração de cantaria realizados no Brasil. Promoveu um debate sobre a evolução das técnicas utilizadas, focando também os temas mão de obra, métodos, materiais e produtos atualmente disponíveis no mercado brasileiro. Foram convidados para essa mesa redonda professores e mestres canteiros participantes do curso de formação profissional no Centro de Conservação e Restauro de Veneza – Itália, em 2001, através do Programa do Ministério da Cultura – Monumenta/IPHAN. Os centros de pesquisa tecnológica existentes em nosso país são raros e pouco requisitados pelos técnicos envolvidos em trabalhos de conservação/restauração de cantarias. O distanciamento desses técnicos em relação aos centros de tecnologia é unanimemente reconhecido por eles. A situação dos profissionais de conservação/restauração em cantaria no Brasil não é fácil, carece de capacitação e de perenidade de obras de restauração e conservação. Buscou-se, nesse Simpósio, fazer uma avaliação sintética do mercado de trabalho e do desenvolvimento tecnológico a partir do Plano de Treinamento e Formação de Mão de Obra, promovido pelo MinC através do Programa Monumenta/IPHAN.Palavras Chave: cantaria, mestres, tecnologiaAbstract: MASTERS IN MASONRY: TECNOLOGY AND PRACTICE.

Teachers and masons who took part in the professional formation course in the Restoration Center of Venice - Italy, in 2001, through the Ministry of Culture - Monumenta / IPHAN Program were invited to this round table. The technological research centers in our country are rarely requested by technicians involved in conservation works. The distancing of these technicians from the technology centers is unanimously recognized by them. The situation of conservation / restoration professionals in masonry in Brazil is not easy, it needs both training and the permanence of restoration and conservation works. This Symposium intended to make a brief evaluation of both the labor market and the technological development based on the MinC - Monumenta / IPHAN Program for Training and Manual Labour Formation Plan.Keywords: masonry, masons, technology
O “protagonismo” das mulheres nas políticas e programas sociais nos governos Dilma
Authors: Tenorio Emilly Marques
Published: May 2017

O presente artigo pretende verificar quais políticas e programas sociais foram defendidos nos anos de governo Dilma (2011-2015) como relevantes especialmente para as mulheres, para saber quais argumentações que são apresentadas para tal “protagonismo”. Apontamos que o fato de ser a primeira mulher presidente do Brasil poderia trazer representatividade e maior visibilidade às pautas feministas, porém as respostas políticas dependem da perspectiva classista adotadas em sua gestão. Como metodologia, realizamos pesquisa documental utilizando a técnica de análise de conteúdo para analisar seus discursos presidenciais, realizados entre 2014 e 2015, período em que ocorreu a transição entre suas gestões. Selecionamos, após a leitura exploratória, os programas “Minha Casa, Minha Vida”, “Bolsa Família” e o “Programa Nacional de Acesso ao Ensino Técnico e Emprego”. Concluímos, a partir da análise dos seus pronunciamentos direcionados às mulheres, que, sob o discurso liberal do empoderamento e autonomia, as mulheres ganham centralidade nas políticas sociais, o que fortalece a individualização e o familismo, incompatíveis com os valores do feminismo socialista.

Authors: A.S. Anilkumar P. Farsanashamin and
Published: May 2017

A field experiment was conducted at College of Agriculture, Padannakkad, Kasaragod, Kerala state during 2012 to 2015 to develop appropriate cost effective practices for enhancing productivity and profitability of coconut based multi-storeyed cropping system involving a combination of coconut, noni, banana and long pepper in coastal sandy soil. The treatments consisted of eight combinations of four levels of NPK (100 per cent, 2/3 rd, 1/3 of the recommended NPK and basin management in the organic pathway) for coconut and two levels of NPK (100 and 75 per cent of the recommended dose) for the component crops in addition to five sole cropping systems namely, coconut (100 per cent NPK), coconut (organic), long pepper (100 per cent NPK), banana (100 per cent NPK) and noni (100 per cent NPK). Pooled analysis of the data revealed that basin management with 75 per cent NPK for component crops was found favourable for increasing the nut yield from 43 to 53 nuts palm-1 year-1. Soil properties and BCR of the system also improved as a result of the same treatment. Highest copra content (160.6 g nut-1) was recorded in the
organic basin management treatment supplied with 100 per cent NPK for component crops. An improvement in the soil nutrient status was also observed compared to the control. 
Diversity and density of tea pests in the tea gardens of Manipur
Authors: R. Varatharajan K. Dhanapati Devi, K. Nishikanta
Published: May 2017

Twenty one species of tea pests have been recorded for the first time from the tea gardens of Manipur which include twelve species of cutting and chewing pests, seven species of sucking pests, a stem borer and a leaf miner. Among them, red spider mite, (Oligonychus coffeae), leaf roller, (Caloptilia theivora), thrips (Mycterothrips setiventris) and aphid, (Toxoptera aurantii) were categorised as important pests and the rest as minor pests based on the observations carried out for one pruning cycle during 2010 to 2013. Field studies had shown that red spider mite (RSM) infested the tea plants all through the year with peak density of 16 mites per leaf per bush in April, whereas occurrence of thrips had been recorded with maximum abundance of 6 thrips per leaf per bush during October. On the other hand, tea aphids infested the plant from March to October with maximum of 200 individuals per 5 cm length of tea shoot in September. The stem borer, Zeuzera coffeae was noticed during March, April and September with an average density of 9.5 borers per 40 bushes. Among the foliage folders, leaf roller was predominant over flush worm and tea tortrix. Occurrence of leaf rolls was noticed from June to November with maximum incidence of 6 larvae per bush in October, but flushworms and tortrix were abundant even in April with the mean of 3 larvae per infested tea bush. Based on the above observation, a pest calendar was prepared for the tea pests of Manipur for planning pest control measures. Besides, 16 species of natural enemies attacking the tea pests are also reported in this article.

Virulence of Phytophthora isolates from Piper nigrum L. and their sensitivity to metalaxyl-mancozeb
Authors: R. Suseela Bhai K.B. Vinitha, M. Anandaraj and
Published: May 2017

Foot rot disease caused by Phytophthora capsici in black pepper is the most destructive disease. A total of 82 isolates from the National Repository of Phytophthora at ICAR-Indian Institute of Spices Research were evaluated for their sensitivity to metalaxylmancozeb and also tested for their virulence. Of the 82 isolates studied, 19 (23.2%) were highly sensitive to metalaxyl-mancozeb and six (7.3%) were comparatively insensitive (EC90 value >40 ppm; range 41.3 to 68.5 ppm). The isolates also varied in the degree of virulence, viz., 34 (41.5%) were highly virulent, 39 (47.6%) moderately virulent, 4 (3.7%) mildly virulent, and 5 (6.1%) non-virulent. There was neither any significant correlation between sensitivity to metalaxyl-mancozeb and virulence nor with the geographical location. 
Influence of organic sources of nutrients on vanilla (Vanilla planifolia) as an intercrop in coconut garden
Authors: V. Krishnakumar, H. P. Maheswarappa, , A. Geetha Kumari Alka Gupta,
Published: May 2017

Performance of vanilla, as influenced by organic source of nutrition when grown as intercrop in coconut garden, was studied in sandy loam soil at ICAR-CPCRI, Kasaragod, Kerala for seven years. Field experiments were carried out with different sources of organic manures, recommended NPK fertilizer and no fertilizer treatments. Application of cow dung slurry (6 tonnes ha-1) resulted in vigorous growth of vine (vine length of 5.5 m) and higher number of beans per vine (208) and a significantly higher mean fresh yield of bean (1.87 kg vine-1). Application of vermicompost (5 kg plant-1) + biofertilizers (Bacillus and Azospirillum) and vermiwash were on par and recorded mean fresh yield of 1.47 kg vine-1 and 1.30 kg vine-1, respectively. Control treatment without fertilizer application recorded significantly lower fresh bean yield (0.55 kg vine-1) due to lower number of beans per vine (72 nos.).  In the rhizosphere of vanilla, no significant difference for either bacterial or actinomycetes population was noticed among the treatments. The fungal population differed significantly among the treatments and the highest population level was found with application of biogas slurry (62.1x103cfu g-1 soil), which was on par with application of cow dung slurry (59x103 cfu g-1 soil). Among the function specific microbial communities, the highest population of  P-solubilisers (98x103 cfu g-1 soil) was recorded in the biogas slurry treatment, and it was the lowest in control and vermiwash application treatments. The average coconut yield realized during experimental period(2004-05 to 2009-10) was 136 nuts per palm, recording 53 per cent increase in yield compared to pre-experimental yield (89 nuts per palm). 
Yield estimation of coconut in Tumkur district of Karnataka
Authors: Basavaraj G.
Published: May 2017

Coconut in India is cultivated mainly in the states of Kerala, Tamil Nadu, Karnataka and Andhra Pradesh which account for more than 90 per cent of area and production of coconut in the country. With about 10 million people dependent on coconut farming and its allied activities, it contributes to more than 83,000 million rupees to the country’s GDP and about 6 per cent to the edible oil pool. However, there are no precise estimates of its production and productivity. The official statistics on area and production of coconut is being published with two years lag by the Department of Economic and Statistics and hence an assessment of surplus/ deficit production and its repercussion in the coconut market economy could not be made many times. Absence of such statistics at the right time for timely dissemination to stakeholders is considered as an impediment for the development and growth of the industry. Coconut Development Board initiated statistical survey for estimation of production of coconut across major coconut growing states in India by undertaking field surveys and yield estimates based on established phenotypic characters of the buttons/ nuts. The estimation was carried out in Tumkur district of Karnataka also which has the highest area under coconut. A total of 406 farms were surveyed in four taluks of the district covering 4060 bearing palms for productivity estimation. The average number of nuts per palm across all age groups for the district as a whole was 98 nuts. The average productivity for Karnataka which was much below to all India average before 2010-11 saw sudden surge post 2011-12. Questions arise as to what are the underlying factors for such sudden spikes. Across many, data capture, estimation and reporting are critical which go on to determine the decision making process on development and growth of the sector. Decisions are formulated on fixation of prices, trade, planning and execution of welfare schemes and policy making. Hence, scientific estimation initiated by Coconut Development Board on production and productivity augurs well for the sector.

Published: May 2017

High yielding hybrids can play an important role in increasing the productivity of oil in the oil palm. With a view to evaluate high yielding new oil palm cross combinations, a field experiment was conducted in different agro-climatic regions of India viz., Zone No-10 Southern Plateau and Hills (Gangavathi, Karnataka), Zone No-12 Western Coastal Plains and Ghats (Mulde, Maharashtra) and Zone No-11 Eastern Coastal Plains and Hills (Vijayarai, Andhra Pradesh) involving ten cross combinations of tenera oil palm (NRCOP 1-10). The data from three locations over two years indicated that, significantly higher annual rate of leaf production per palm was recorded in NRCOP-6 (21.7) compared to NRCOP-3 and it was on par with other hybrid combinations. Significantly higher sex ratio was recorded with NRCOP-4 (63.1%) compared to NRCOP-1 (54.6%) and NRCOP-6 (54.8%) and was on par with other hybrid combinations.The hybrid cross combination, NRCOP-4 recorded significantly higher fresh fruit bunches (FFBs) yield 12.5 t ha-1 compared to NRCOP-1, NRCOP-3, NRCOP-7 and NRCOP-9 and it was on par with remaining hybrids and a similar result in bunch weight and number of bunches per palm was recorded. Pooled data on FFB yield for 2013-15 indicated that the hybrid combination NRCOP-4 which recorded higher FFB yield (12.6 t ha-1) at Gangavathi and at Vijayarai (22.6 t ha-1) have better prospects for adaptation under Tungabhadra command area and coastal region of Andhra Pradesh. For Konkan region of Maharashtra, the hybrid NRCOP-8 recorded the highest FFB yield.
Fruit rind constituents in nutmeg (Myristica fragrans) morphotypes
Authors: Mini Raj N. , Vikram H.C. , Philip Manu , Deepa E.T.
Published: May 2017

Rind or pericarp is the outermost part of nutmeg fruit which is thick and fleshy. Fresh rind, contributing 80 to 85 per cent of total fruit weight, has an astringent taste with aromatic flavour. Due to these qualities, the use of rind for food purpose is restricted. At the same time its therapeutic property, especially its anti-oxidant, anti-microbial and anti-diarrhoeal effects, have generated interest in nutmeg rind. Major interest of the processors is the biochemical constitution of the rind. In the present study, 17 distinctly featured nutmeg accessions selected from core collections in central Kerala were employed for biochemical analysis of rind. A total of 10 constituents of ripe rind were estimated using standard analytical techniques. Data were statistically analysed and sub groups formed using DMRT. The range of variation was 87.1 to 89.1 (mg 100 g-1) for ascorbic acid, 0.2 to 1.08 per cent for pectin content (calcium pectate), 0.21to 1.85 (g 100 g-1) for protein, 0.3 to 1.23 (g 100 g-1) for starch, 27.8 to 57.6 (mg 100 g-1) for total phenol, 143.3 to 750.0 (mg 100 g-1) for tannin, 2.01 to 2.57 per cent for total minerals and 2.06 to 3.65 per cent for crude fibre. Since varied overlapping sub-groups were obtained constituents wise, the method to make decisions jointly on a number of dependant characters was co-opted. The final score is an indicator of the relative superiority of the accessions in terms of the biochemical constituents of rind. The accessions were categorized for various end uses based on the score obtained for each constituent. The variation in biochemical composition may be due to inherent genetic character of the tree as also the geographic location and management practices followed. Based on the composition, the nutmeg rind, which at present is discarded as a farm waste, could be utilized for value addition in the food, nutraceutical and pharmaceutical sectors.

Published: May 2017

Technology integration for enhancing productivity and income from coconut farming, facilitated through stakeholder participation, was a major objective of the NAIP sub-project on ‘Value chain in coconut’ implemented in a consortium mode with ICAR-Central Plantation Crops Research Institute, Kasaragod as the lead institute. To achieve this objective, 10 clusters of coconut farmers were formed under the project in selected panchayats of Kasaragod district in Kerala state. A total of 534 farmers covering 250 ha participated in the project interventions. Appropriate production technologies were integrated in their holdings which included intercropping, growing of leguminous crops in the coconut basin, organic recycling through vermicomposting and integrated nutrient management. Group action was initiated among the farmers for taking up need-based integrated disease management measures especially to control bud rot disease of coconut. Knowledge and skill upgradation of farmers on the selected technologies were achieved through various institutional and off campus training programmes. The net income from the coconut farming in small and marginal holdings could be increased through the interventions under the project. Technology integration in the holdings also resulted in the increase of coconut productivity from 60 to 112 nuts per palm. Technology integration in small and marginal coconut holdings for higher productivity and income through Community Based Organizations approach is scaled up by other agencies like Coconut Development Board for implementing development/extension programmes.
Introducing an Educational Tool for Learning Branch & Bound Strategy
Authors: Zumaytis Sofriesilero , Karnalim Oscar
Published: May 2017

Abstract—According to our informal survey, Branch & Bound strategy is considerably difficult to learn compared to other strategies. This strategy consists of several complex algorithmic steps such as Reduced Cost Matrix (RCM) calculation and Breadth First Search. Thus, to help students understanding this strategy, AP-BB, an educational tool for learning Branch & Bound is developed. This tool includes four modules which are Brute Force solving visualization, Branch & Bound solving visualization, RCM calculator, and case-based performance comparison. These modules are expected to enhance student’s understanding about Branch & Bound strategy and its characteristics. Furthermore, our work incorporates TSP as its case study and Brute Force strategy as a baseline to provide a concrete impact of Branch & Bound strategy. According to our qualitative evaluation, AP-BB and all of its features fulfil student necessities for learning Branch & Bound strategy. Keywords— Educational Tool; Branch & Bound; Algorithm Strategy; Algorithm Visualization

La reparación de la hernia ventral (HV) con separación de componentes (SC) representa a un grupo de técnicas quirúrgicas diferentes en su concepción, desarrolladas para pacientes que requieren una reconstrucción importante de la pared abdominal. Los métodos descritos comparten elementos clave, como son la liberación del aponeurótico con avance miofascial, la reconstrucción de la línea alba y la creación de vastos espacios dentro de la pared abdominal que aseguren una amplia disposición y fijación de la malla. La diferencia entre la separación de componentes anterior (SCA) y la separación de componentes posterior (SCP) es la creación y localización de estos espacios. Los métodos de SCP permiten la colocación de una malla retromuscular, lo que la diferencia favorablemente en la bibliografía por las tasas de complicaciones de herida y de recurrencia. La SCP con liberación de transversos tiene diferentes ventajas frente a la SCA: permite una disección lateral extensa en el espacio virtual avascular por debajo del músculo transverso del abdomen, con lo que se crea de esta forma el espacio con la ubicación adecuada e ideal para implantar la malla, preservando al mismo tiempo el aporte neurovascular completo a la pared abdominal anterior. La liberación del músculo transverso del abdomen es la que permitirá medializar ampliamente los músculos rectos y la reconstrucción de las capas de la pared abdominal posterior y anterior con la malla, quedando esta en un «bolsillo» retromuscular bien vascularizado y alejado de la piel. Además, dicha posición retromuscular de la malla permitirá una amplia sutura en los defectos difíciles (subxifoideo, subcostal y suprapúbico). Basado en estas ventajas y en la baja tasa de recurrencia reportada (3-5 %), la SCP con liberación del músculo transverso abdominal es el método de reparación pretendidamente preferido para el manejo de pacientes que requieran una reparación de las HV de gran tamaño.
Tratamiento de hernia ventral compleja contaminada en dos etapas
Authors: Barbosa Eva , Correia Joana , Ferreira Fernando
Published: May 2017

El tratamiento de las hernias ventrales complejas contaminadas o muy contaminadas es un reto aún sin una estrategia técnico-quirúrgica definida en la literatura médica. Presentamos el caso de un hombre con una hernia ventral compleja muy contaminada de la prótesis sintética por Staphylococcus aureus resistente a meticilina, en el que se optó por una cirugía en dos etapas con una semana intercalada de tratamiento antibiótico. En el posoperatorio desarrolló un seroma tratado de forma conservadora, y a los 6 meses de seguimiento no se evidencia recidiva ,“abombamiento” de la pared abdominal ni “rechazo” de la prótesis. El resultado favorable obtenido con esta estrategia elegida -técnica en 2 etapas- induce a conjeturar si el manejo terapéutico seguido en este paciente podría ser efectivo para evitar desmasiado tiempo de convalecencia en hernias incisionales complejas contaminadas.

Authors: Roche Sebastián , Bertone Santiago , Cetolini Fernando , Campana Juan P. , Brandi Claudio
Published: May 2017

Introducción: La hernia obturatriz es una entidad poco frecuente, cuya incidencia oscila entre 0.05 % y el 1.5 %, con una morbimortalidad cercana al 40 %. Caso clínico: Mujer de 85 años, que comienza con náuseas, vómitos y distensión abdominal. Se realiza radiografía de abdomen y tomografía computarizada (tac), donde se observa hernia obturatriz izquierda. Se decide laparoscopia exploradora. Se reduce la hernia y se coloca malla de polipropileno preperitoneal. Discusión: La hernia obturatriz es una entidad poco frecuente, que se presenta en mujeres ancianas, multíparas y desnutridas. Su diagnóstico suele ser tardío, por lo que es una entidad con alta mortalidad, cercana al 40 %. La tomografía computarizada es el método diagnóstico por elección, y el abordaje laparoscópico, el tratamiento de primera opción. Conclusión: El objetivo principal en estos pacientes es realizar un diagnóstico precoz y poder, de esa manera, disminuir los índices de mortalidad. Ante la sospecha clínica, se solicitará tomografía computarizada de abdomen y pelvis, con la idea de no demorar la intervención quirúrgica.

Crisis Civilizatoria y Utopías: El Buen vivir como posibilidad
Authors: Günther Griselda , Arroyo Tania
Published: May 2017

ResumenEste trabajo tiene por objetivo reflexionar sobre tres cuestiones: ¿Qué son la utopía y el pensamiento utópico?, ¿qué función cumplen ante la crisis civilizatoria actual? y ¿qué tan pertinente es pensar hoy en propuestas como la de Buen vivir como utopía? Para ello se expone brevemente cómo se entienden la utopía y el pensamiento utópico, recuperando el trabajo de algunos autores que se consideran, en este caso, claves. El objetivo es encontrar características comunes que se conjugan para construir una noción actual de utopía y de pensamiento utópico. Posteriormente, se desarrolla la idea de necesidad de las utopías ante el momento crítico actual por el cual atraviesa el planeta y la humanidad. Finalmente, concluimos poniendo en diálogo la utopía y la crisis civilizatoria a través de la propuesta emergente del Buen vivir como alternativa al desarrollo y sus potencialidades.Palabras-clave: Utopía, Buen vivir, Crisis Civilizatoria, Pensamiento Utópico, Vivir Bien Crise Civilizacional e Utopias: Boa Vida como uma PossibilidadeResumoEste trabalho tem como objetivo refletir sobre três questões: o que são a utopia e o pensamento utópico?

In order to feed these discussions, we briefly describe how utopia and utopian thinking are understood by recovering the work of some key authors. Our main objective is to find common characteristics that will allow us to combine and propose an updated notion of utopia and utopian thinking. Subsequently, we elaborate on utopia’s necessity for current world and humanity crisis. Finally, we conclude our discussion by addressing utopia and the civilization crisis through the emerging proposal of Buen vivir as an alternative for development and potentiality.Keywords: Utopia, Utopian Thinking, Buen Vivir, Vivir Bien, Living Well, Crisis of Civilization
Technology Update: Adjustable, Supramolecular Viscosity Modifiers as Displacement Fluids in EOR
Authors: Akbulut Mustafa , Temizel Cenk
Published: May 2017

Technology Update

We report a novel type of viscosity modifier relying on the supramolecular assemblies that have pH-adjustable viscosities and robust tolerance against high temperatures and salinities, and are resistant to shear-induced degradation. This technology is developed collaboratively by Texas A&M University, Incendium Technologies, and VaalbaraSoft.

When reservoir oil is displaced by plain waterflooding, the injected water fingers through the reservoirs because of the high mobility ratio (Rachford Jr. 1964). Water fingers leave most of the oil behind, which leads to inefficient oil recovery. Hence, the viscosity modifiers are often added in the displacing fluid, (i.e., water) to better match the viscosity of reservoir oil and enable a uniform advance of the waterfront to effectively sweep the reservoir oil.

Currently, for oil recovery applications, most commonly used viscosity modifiers are water-soluble polymers such as hydrolyzed polyacrylamide, polyvinyl alcohol, and poly(vinylpyrrolidone) (Taylor and Nasr-El-Din 1998). Likewise, water-soluble biopolymers, in particular polysaccharides such as xanthan and guar, are also used in some fields (Alquraishi and Alsewailem 2012).

Current Technology Limitations

While the above-mentioned viscosity modifiers can satisfy part of the oil recovery needs, these polymers still experience some challenges that hinder their effectiveness. For example, when the viscosity of reservoir oil is high, so should the displacing fluid be to match the mobility ratio. The current heuristics suggest that polymer flooding should be applied in reservoirs with oil viscosities between 10 and 150 cP (Taber et al. 1997).  

The key factor limiting the recommended range is that for oil viscosities greater than 150 cP, the injected-water-viscosity values required for a favorable mobility ratio correspond to prohibitively low values of polymer injectivity. In addition, pumping high-viscosity displacing fluids tends to lead to clogging in oil wells, which results in a major economic well operating loss.  

One potential solution is to use dis-placement fluids with an adjustable viscosity, with the fluid having a low viscosity at the injection site and a high viscosity upon reaching the oil phase. Furthermore, having an adjustable-viscosity displacement fluid can help to reduce pumping-related operational costs because pumping efficacy generally decreases as fluid viscosity increases. The above-mentioned polymers do not offer viscosities that can be controlled in such a fashion.
The Future of the Oil Sands Depends on One Thing: Totally Rethinking Everything
Authors: Rassenfoss Stephen
Published: May 2017

Shell and Marathon have agreed to sell most of their oil sands operations. Exxon Mobil recently removed 3.5 billion bbl of the ultraheavy crude from its proved reserves because it no longer plans to develop them any time soon, following a similar move by ConocoPhillips. 

In a world with a surplus of oil production options, the oil sands suffers because the cost of development is high and the value of ultraheavy crude is low, with oil sands bitumen selling for USD 15/bbl less than the benchmark for light crude, and these projects require big financial commitments stretching out for decades.

“They (oil sands) are the most expensive kid on the block and that is not a good place to be,” said Ron Sawatzky, a principal researcher for InnoTech Alberta, and chair of the SPE Canada Heavy Oil Technical Conference. “US shale producers are the biggest competitors for oil sands. We cannot match the nimbleness of those guys.”

Among those competitors are ExxonMobil and ConocoPhillips, with large operations in unconventional plays in the US and Canada and significant oil sands operations.

“We are seeing the same technologies and innovations driving lower costs and greater opportunities,” in the oil sands, Ryan Lance, chief executive officer at ConocoPhillips, said during a presentation at the March CERAWeek conference in Houston. But he keeps asking his oil sands team: “How can you do projects with a 3–5-year cycle time so you can adapt” to a business with big unexpected price swings.

Those who work in the oil sands are learning how to react faster to prepare for when oil may again be in short supply. “At Suncor we will spend around USD 200 million on technology in 2017 because business as usual does not cut it,” said Gary Bunio, general manager, strategic technology for oil sands, at Suncor. “We are working on things we will put in over a couple years, and things that will take a decade.”

The payoff for reviving future growth is huge—oil sands resources are estimated at 135 billion bbl according to the US Energy Information Administration—and there is cash flow to invest in technology. Efficient producers such as Suncor have reduced operating costs to turn a profit with oil prices as low as USD 35/bbl.
Technology Focus: Offshore Drilling and Completion (April 2017)

Technology Focus

Intervention-free wells, intelligent completions, automated and selective smart tools—this veritable buzzword bingo several years ago offered the real promise of some advancement but, unfortunately, mostly delivered consistent failure and disappointment. That was a period when the industry was littered with a swath of great technologies, but they were deployed in such a haphazard and almost incoherent way that they were surely doomed to failure from the offset. Although these technologies often were presented as magic-bullet solutions, few of their trials considered the necessary detail of the greater system within which they were deployed and functioned, an approach that ultimately tainted their delivery and results.

That has since changed. In the present day, the industry has developed a deep and healthy respect for systems-engineering processes and the associated full considerations during the deployment and trial of new technologies and techniques. The result of this uptake has been a significant improvement in the successful use and broader deployment of these automating, enhancing, and attractive technology options.

This month, I would like to showcase just a handful of the studies that demonstrate deployment of such solutions within long-established and mature systems where they have been considered in an integrating, sympathetic, and, as a direct result, highly successful way. This overall-system appreciation and consideration has finally allowed these enhancements and technologies to enjoy their newfound and sustained success.
