The countable type properties in free paratopological groups
Authors: Lin Fucai , Liu Chuan , Zhang Kexiu
Published: May 2017

A space X is of countable type (resp. subcountable type) if every compact subspace F of X is contained in a compact subspace K that is of countable character (resp. countable pseudocharacter) in X. In this paper, we mainly show that: (1) For a functionally Hausdorff space X, the free paratopological group FP(X)and the free abelian paratopological group AP(X) are of countable type if and only if X is discrete; (2) For a functionally Hausdorff space X, if the free abelian paratopological group AP(X) is of subcountable type then X has countable pseudocharacter. Moreover, we also show that, for an arbitrary Hausdorff μ-space X, if AP2(X) or FP2(X) is locally compact, then X is a topological sum of a compact space and a discrete space.

Authors: Huyen Nguyen Ngoc , Khiem Nguyen Tien
Published: May 2017

Dynamic analysis of FGM Timoshenko beam is formulated in the frequency domain taking into account the actual position of neutral plane. The problem formulation enables to obtain explicit expressions for frequency equation, natural modes and frequency response of the beam subjected to external load. The representations are straightforward not only to modal analysis and modal testing of FGM Timoshenko beam with general end conditions but also to study coupling of axial and flexural vibration modes. Numerical study is carried out to investigate effect of true neutral axis position and material properties on the modal parameters.
Distributed fibre optic sensing of strains on buried full-scale PVC pipelines crossing a normal fault
Authors: Ni P. , Moore I. D. , Take W. A.
Published: May 2017

Seismic faulting is extremely detrimental to buried pipelines owing to bending moments and axial forces generated by the soil–pipe interaction. Pipe responses to ground rupture are usually evaluated by beam-on-spring analysis. However, the empirical data used to define the spring response were obtained for steel pipes with high flexural stiffness and the effectiveness of the resulting spring stiffness values for flexible pipes is questionable. This paper presents full-scale tests undertaken using a new split-box apparatus which permits the testing of pipes in dry sand subject to a normal fault with dip angle of 90°. Four polyvinyl chloride (PVC) pipes (various diameters), one instrumented with strain gauges and three instrumented with fibre optic sensors, were tested to provide experimental evidence for flexible pipes. The research includes confirmation of the effectiveness of fibre optic strain measurement, which has the advantage of providing much more data than the limited discrete values obtained from conventional strain gauges. However, the fibre optic strain sensing technique is limited to strain values below 1%. The prototype-scale testing permits assessment of the efficacy of the current design approaches, including the relative success of accounting for reduced spring stiffness or patterns of imposed deformation.
Gender Perspective of Rural Livelihood and Household Income: Case Study of a Village in Odisha
Authors: Jadhav P. V.
Published: May 2017

A person’s livelihood consists of her/his abilities, assets and activities required for a means of living. A gender analysis in the context of rural livelihood enables us to identify the different activities that men and women do. This paper intends to examine the role of gender in determining livelihood aspects like occupation structure and migration. It also investigates the role played by gender in determining employment, family income, and income distribution of individuals. The study is based on a census of 143 households of a village from the Bhadrak district of Odisha. The study observes significant gender gap in occupation structure, and income distribution across gender. If women are employed, household income increases significantly.
Performance of Regional Rural Banks in Indian Economy: An Overview
Authors: Barman Bhajan Chandra
Published: May 2017

Regional Rural Banks (RRBs) also known as ‘Gramin’ bank have emerged as an important rural credit delivery institution in India for meeting the credit requirements of the rural poor. These rural banks have been working for more than four decades in the Indian rural credit delivery system. They are state sponsored, regionally based and rural oriented commercial banks. The basic objective of this study is to analyse the growth and financial performance of RRBs in India from the period 2013 to 2016 based on some selected parameters like area coverage, profit and loss making RRBs, trends of profits and accumulated losses, overall position of non-performance assets and recovery rate. We have mainly used secondary data collected from various journals, books and available websites related to regional rural banks. The review of performance of RRBs shows the good growth performance of RRBs for providing better banking services to the rural people. From the analysis, we can draw the conclusion that rapid expansion of RRBs has been able to substantially reduce the regional disparities in respect of banking facilities in India.
Interaction between Monetary and Fiscal Policy: Empirical Evidence from India
Authors: Mallick Arundhati , Sethi Narayan
Published: May 2017

Monetary policy and fiscal policy have their own perspective towards maintaining economic stability of the country. However, for a well- functioning economy, they need to work in coordination with each other. In this paper we are empirically examining the interaction between monetary and fiscal policy by using Vector Error Correction Model (VECM) for the period of April 2010 to March 2015. The study also discusses game theoretic approach to know about the strategic interaction between monetary and fiscal policy. The study uses change in gross fiscal deficit and output to represent fiscal policy and inflation and interest rate to represent the monetary policy. The results indicate that fiscal policy responds well to any changes in monetary policy but reverse is not taking place.
Anti-Neu5Gc Antibody Kit Protocol - Western Blot v2
Authors: Miller Kelsey
Published: May 2017

The Anti-Neu5Gc Antibody Kit contains the essential monospecific polyclonal chicken IgY antibody, along with a negative control primary antibody to detect the presence of Neu5Gc on glycoconjugates by Western blot (WB). Samples to be evaluated are first subjected to SDS-PAGE, followed by transfer to a nitrocellulose or polyvinylidenedifluoride (PVDF) membrane. The membrane is then incubated with affinity-purified polyclonal anti-Neu5Gc to determine the presence of Neu5Gc on the protein of interest. The antibody provided in this kit has been shown to identify as little as 5 pmol of Neu5Gc per ug glycoprotein, which is at or below the current detection limit for conventional analysis by acid release, purification, DMB derivatization, HPLC, and electrospray mass-spectrometry. The Western blot provides additional information in that it confirms that Neu5G is directly linked to the glycoprotein of interest rather than to an accompanying sample component.

Political Participation and Power Relations in Egypt: The Scope of Newspapers and Social Network Sites
Authors: Shehata Mostafa
Published: May 2017

The political use of media in Egypt post-2011 revolution brought about drastic transformations in political activism and power structures. In the context of communication power theory, this article investigates the effects of newspapers and social network sites on political participation and political power relations. The research employed a mixed methodology, comprised of a survey of 527 Egyptian youth and semi-structured interviews of 12 political activists and journalists. The results showed a significant relationship between reading newspapers and youth’s political participation, but not between using social network sites and political participation. In addition, newspapers and social network sites were platforms for a series of conflicts and coalitions that emerged between pro- and anti-revolution actors. Despite the importance of social network sites as key tools for informing and mobilizing the public, they eventually failed to empower new political actors, and this was because old actors, supported by newspapers and other mainstream media, managed to obstruct the new actors’ progress.

Authors: Gupta Taru , Gupta Sangeeta , Deepika . , Gupta Nupur
Published: May 2017

Background: Peripartum hysterectomy is the most dramatic operation in modern obstetrics and is generally performed when all conservative measures fail to achieve haemostasis in the setting of life threatening haemorrhage. The objective was to review all peripartum hysterectomies performed at a tertiary care centre over a ten-year period from 2007 to 2016 to determine the incidence, types, indications and maternal outcome and also to study the changing trendsMethods: This was a retrospective, observational, analytical study of parturient women requiring peripartum hysterectomy (PH). We looked at data over a ten-year period, from January 2007 to December 2016. Case records were reviewed for socio-demographic characteristics of the patients, type and indications for the hysterectomy performed, booking status of patients, mode of delivery, gestational age at delivery and maternal outcome. Change in trends of the rate and indications of peripartum hysterectomy at the centre was also reviewed.Results: The overall rate of peripartum hysterectomy was 1/876 deliveries. The rate of peripartum hysterectomy had a 4-fold rise from 2007 to 2016.The primary indication was abnormal placentation which included morbidly adherent placentation 22/59 (37.2%) and placentapraevia 5/59 (8.4%), followed by intractable atonic haemorrhage in 35.6% of cases. Abnormal placentation as an indication for PH increased significantly form 34.6% (2007-2011) to 54.54% (2012-2016). After hysterectomy, 56% cases were admitted to ICU. All patients needed blood transfusion. Maternal mortality was 10.1%.Conclusions: Peripartum hysterectomy is a most demanding obstetric surgery performed in very trying circumstances of life threatening hemorrhage. The indication for emergency peripartum hysterectomy in recent years has changed from traditional uterine atony to abnormal placentation.

Background: Hypertensive disorders complicate 5 to 10% of all pregnancies. Despite the still unexplained pathogenesis, endothelial dysfunctions and inflammatory mediators are thought to be responsible for the pathogenesis gestational hypertension and pre-eclampsia. Aims and objective of the study was to determine the serum levels of cell adhesions molecules - VCAM-1 and ICAM-1 and endothelial inflammatory markers TNF-α and homocysteine in normal pregnancies, Gestational Hypertension and in Pre-eclampsiaMethods: The cross-sectional study was carried out in Department of Obstetrics and Gynecology and Biochemistry, ESI-PGIMSR, New Delhi between October 2013-April 2015. 150 patients who gave informed written consent were enrolled and were divided equally in three groups of 50 each (normotensive, gestational hypertensive and pre-eclamptic patients). Three groups have been compared in terms of variables such as age, BMI, gestational age, systolic and diastolic blood pressure, platelet count, AST, ALT, mode of delivery, neonatal weight, VCAM-I, ICAM-I, homocysteine and TNF-alpha concentrations.Results: We found the higher concentrations of vascular cell adhesions molecules (VCAM-1 and ICAM-1) and inflammatory mediators (homocysteine and TNF α) in gestational hypertensive patients and in pre-eclamptic patients. Out of four markers, concentrations of ICAM-1 was found in largest proportions and it was also statistical significant. P value was <0.001. Though in our study concentration VCAM-1, homocysteine and TNF-α were also high in gestational hypertensive groups as compared with normotensive patients, but they were not statistical significant.Conclusions: We conclude that higher concentrations of vascular cell adhesions molecules and inflammatory mediators may be responsible for hypertensive disorders of pregnancy suggesting the role of endothelial dysfunction as a central pathogenic feature in development of preeclampsia.

Educação ambiental e mediação de conflitos neopentecostais no Parque Nacional da Tijuca
Authors: Maciel Glaucio Glei , Gonçalves Rafael Soares
Published: May 2017

O presente artigo procura analisar os conflitos envolvendo o uso público religioso neopentecostal em áreas do Parque Nacional da Tijuca, assim como as estratégias de enfrentamento desenvolvidas em atividades de educação no processo de gestão ambiental pública no âmbito do Projeto Elos da Diversidade. Empregou-se pesquisa qualitativa, integrando uma breve revisão bibliográfica, documental e aplicação de questionários. Os resultados evidenciam que o modo de pensar e agir conservacionista contribui para o acesso à natureza de forma restrita, com prioridade para a visitação turística mercadológica. Observa-se, nesse contexto, a violação ao direito à liberdade e manutenção religiosa, na medida em que se desenvolve a intolerância, a discriminação e a injustiça ambiental. Em face disso, verifica-se que a partir de uma visão de educação ambiental integradora e libertadora é possível diluir o pragmatismo científico e os conflitos entre as diferentes percepções religiosas e conservadoras da natureza, considerando a criação de políticas públicas que fomentem a inserção da racionalidade dos direitos à liberdade de expressão do sagrado no campo ambiental.

Published: May 2017

O artigo examina os efeitos da proteção social brasileira desenhada a partir da década de 1980 para as relações de gênero. Visa evidenciar dilemas e paradoxos que atravessam as lutas e análises feministas em torno da conquista de direitos das mulheres à igualdade social, na medida em que tem de lidar com a afirmação da diferença como parte de seus pressupostos. Para tanto, são problematizadas algumas políticas e programas formulados no campo da saúde, educação e assistência social, bem como a trajetória das lutas feministas até a contemporaneidade. Defende que o “familismo” e a “feminilização” das políticas reatualizam tradicionalismos nas relações de gênero no âmbito das ações de proteção social, especialmente no que tange à produção de cuidados. Aponta desafios para a construção de políticas de gênero que articulem as diversas dimensões dos sujeitos.

Authors: Vatsaraj Meenal Suryakant , Parab Rajan Vishnu , Bade Prof.D.S
Published: May 2017

Anomalous behavior detection and localization in videos of the crowded area that is specific from a dominant pattern are obtained. Appearance and motion information are taken into account to robustly identify different kinds of an anomaly considering a wide range of scenes. Our concept based on histogram of oriented gradients and markov random field easily captures varying dynamic of the crowded environment. Histogram of oriented gradients along with well known markov random field will effectively recognize and characterizes each frame of each scene. Anomaly detection using artificial neural network consist both appearance and motion features which extract within spatio temporal domain of moving pixels that ensures robustness to local noise and thus increases accuracy in detection of a local anomaly with low computational cost. To extract a region of interest we have to subtract background. Background subtraction is done by various methods like Weighted moving mean, Gaussian mixture model, Kernel density estimation.
Decomposition and release of nutrients from leaf litter in rubber plantations
Authors: Mercykutty Joseph Geetha Jose and
Published: May 2017

Establishment of cover crop has been a standard scientific agronomic intervention in rubber (Hevea brasiliensis) plantations. Natural leaf fall in rubber plantations is an unaccounted phenomenon which also improves the physicochemical properties and biological activities of soil. A comparison of the decomposition of leaf litter from different sources in soil and the release of  utrients from them has been attempted in this study through a field experiment. Studies indicated that the degradation and release of nutrients to the soil pool was mainly decided by the leaf chemistry and degradability of the litter. Rubber litter had its own edge over other leguminous cover crop litter, in providing a sustained release of potassium, calcium and magnesium owing to its slow and steady mineralization rate compared to cover crops. Higher content of nutrients was recorded in degraded litter in comparison to fresh sources. Legume cover crops are capable of enhancing the bacterial and fungal populations in soil compared to nonleguminous crops in rubber plantations.
Impact of area-wide extension approach for bio-management of rhinoceros beetle with Metarhizium anisopliae
Authors: Chandrika Mohan P. Anithakumari, K. Muralidharan
Published: May 2017

Area-wide community extension approach (AWCA) was pilot tested for bio-management of rhinoceros beetle in Edava panchayat of Thiruvananthapuram district, Kerala state during the period 2010-2013. It focused on holdings having potential breeding sites of the pest and were treated with green muscardine fungus (GMF) Metarhizium anisopliae (Metsch.), multiplied at farm level by trained farm women groups. The project was implemented as participatory action research in an area of 520 ha of coconut involving over 5500 small and marginal farmers and stakeholders.  AWCA proved to reduce the variability of technology impact in pest management compared to individual level of adoption. Significant reduction in the percentage incidence of rhinoceros beetles (72.9 ± 9.3 to 58.1 ± 9.3) was achieved in Edava panchayat whereas, it was more or less same (74.5%) during the period 2010-2013 in a non-intervention area (Kottamkara panchayat in Kollam district), where, only conventional extension approach followed.  Similarly the average number of symptoms in coconut fronds per palm was also found to be reduced in AWCA area. It ranged from 1.6 to 4.6 before interventions and reduced to a range of 1.0 to 2.8 after interventions. In the non-intervention area it remained almost same (2.9 and 3.0 cuts per palm, respectively in 2010 and 2013). Impact of AWCA was observed to be more or less geographically contiguous on depicting the percentage reduction in severity of rhinoceros infestation in different wards of Edava panchayat using GIS tools.
Parental contribution analysis in hybrids bred for vascular streak dieback (VSD) disease resistance in cocoa
Authors: P.A. Jayasree J.S. Minimol, B. Suma, Mahiya Ummer
Published: May 2017

Vascular streak die back (VSD) disease caused by Oncobasidium theobromae (now renamed as Ceratobasidium theobromae), is one of the major threats in cocoa growing countries, mainly becauseit cannot be controlled by any chemical application. In India, this disease outbreak took place during 1990 and it became an unmanageable problem of cocoa trees. Knowing the importance of resistant hybrids for controlling this disease, Kerala Agricultural University took up resistant breeding programme. It was a massive breeding programme which resulted in production of 5921 hybrid seedlings. After nursery screening of these hybrids by subjecting to heavy inoculation load for more than two years from March 1996 to June 1998, only 566 seedlings survived and they were field planted during June 1998. When relative efficiency of mother plants to transfer resistance to their progenies was estimated, it was seen that G VI 126 (Scavina 6) showed maximum recovery of 32.6 per cent after fifteen years of screening. Comparison of efficacy of male parents indicated that G VI 55 showed maximum recovery of resistant parents (168 nos.). During the entire period of investigation, 267 hybrids were found free from the disease. Out of this, only 51 recorded satisfactory yield levels. All these hybrids showed high value for selection differential (S) indicating maximum genetic gain.These hybrids can be used as mother plants for establishing polyclonal garden, as VSD disease resistance is highly heritable and polygenically controlled. The resistant hybrids identified (both high and low yield) can be utilized for further studies employing conventional and molecular breeding methods.

Evaluation of molecular diversity of ex situ conserved germplasm of palmyrah (Borassus flabellifer L.) accessions using RAPD markers
Authors: K.T. Venkataramana, Jiji George, , M.K. Rajesh P. Nainar , Karun Anitha
Published: May 2017

The genetic relationship of 96 palmyrah palms, consisting of 24 indigenous accessions from Tamil Nadu and Andhra Pradesh, was investigated using Random Amplified Polymorphic DNA (RAPD) markers. Hundred and eighty primers were used initially to identify the polymorphic primers in six random samples and 10 polymorphic primers were selected to amplify the 96 palms. These 10 primers produced a total of 112 reproducible bands and out of them, 41 fragments (36.6 %) showed polymorphism.  The number of bands produced with each primer varied from seven to 15 with an average of 11.2 bands per primer.  The percent polymorphism ranged from 7.7 to 71.4 with an average of 37.4 per cent when all the primers were taken collectively.  UPGMA grouped all the accessions into two major clusters at 0.85 similarity value. The highest similarity value (0.96) was observed between the accessions KLKM-8 and THY-54 and the lowest similarity value (0.782) was obtained between ANBI-17 and RCML-11. The relatively low polymorphism suggests a narrow genetic diversity of palmyrah populations from which the present accessions have been derived and maintained over the years.
Investigations on developing a key for identification of elite nutmeg tree
Authors: Vikram H.C. , Mini Raj N. , Krishnan S.
Published: May 2017

Nutmeg (Myristica fragrans Houtt.) is unique among tree spices, as the donor of two distinct spices; nutmeg and mace. Yield is a complex phenomenon in nutmeg. Fruit yield per tree is the targeted quantitative parameter which is dependent on several other yield related components. Hence, an attempt was made towards identification of an elite nutmeg tree using desirable characteristics which are easily measurable and recognizable. Forty six morphotypes of nutmeg selected from core collections in the Chalakudy river basin in Kerala in the age group of 15 years formed the material for study. These samples of nutmeg represented almost all nutmeg growing tracts of Kerala. The accessions were evaluated based on 51 qualitative and 38 quantitative characteristics and grouped based on similarities. Thirteen key quantitative characters were selected based on their impact on yield as well as commercial importance.The qualitative clusters were ranked based on relative best performance of the perceived key characters. Database was generated for the key characters and from this database, plausible value of each character was predicted. Accordingly, an elite nutmeg tree may be characterized as having the ideal characteristics with approximate values viz. tree height (8 m), canopy spread (E-W: 7 m, N-S: 8 m), number of flowers (6 per 10 cm2), fruit set percentage (37), number of fruits m-2 (19), fruit weight (81 g), thickness of pericarp (14 mm), dry mace weight (2 g), dry nut weight (10 g), kernel weight (7 g), ratio of nut to mace (6.6) and number of fruits per tree (3342). It is a simple key involving characters which are measurable and recognizable at the farmer level.

Published: May 2017

Calamus shendurunii is an endemic rattan of Western Ghats having restricted distribution and limited population. As a prerequisite to device an appropriate method for ex situ conservation of the species, desiccation and cryopreservation of seeds and zygotic embryo has been studied. Seeds extracted from ripened fruits possessed 35 per cent moisture content and exhibited 97 per cent germination. Desiccation to 28 per cent moisture content reduced the germination to 77 per cent. Desiccation below 14 per cent moisture content caused complete loss of seed germinability. Seeds stored under ambient conditions (28±2oC/60% RH) for more than seven days reduced germination to less than 40 per cent. Thus, conventional storage is not effective for their ex situ conservation. As an alternative method, excised zygotic embryos were subjected to desiccation and storage in liquid nitrogen. The embryos tolerated desiccation down to 5 per cent exhibiting 60 to 90 per cent germination upon culture into MS medium. Desiccated embryos subjected to liquid nitrogen exposure showed post freeze recovery and germination (80-90%) equal to that of desiccated control samples. Thus the study proved the extreme recalcitrance of C. shendurunii seeds and embryo cryopreservation as an alternative method of their ex situ conservation in gene banks.

Methodology for a Dump Design Optimization in Large-Scale Open Pit Mines
Authors: Puell Ortiz Jorge
Published: May 2017

Dump design and scheduling are critical elements to effective mine planning, especially if several of them are required in large-scale open pit mines. Infrastructure capital and transportation costs are considerable from an early stage in the mining project, and through the life-of-mine as these dumps gradually become immense structures. Delivered mining rates, as well as certain spatial and physical constraints, provide a set of parameters of mathematical and economic relationship that creates opportunities for modelling and thus facilitates the measuring and optimization of ultimate dump design by using programming and empirical techniques while achieving economic objectives. This paper presents a methodology to model and optimize the design of a mine dump by minimizing the total haulage costs. The proposed methodology consists on: (i) Formulation of a dump model based on a system of equations relying on multiple relevant parameters; (ii) Solves by minimizing the total cost using linear programming and determines a ‘preliminary’ dump design; (iii) Through a series of iterations, modifies the ‘preliminary’ footprint by projecting it to the topography and creates the ultimate dump design. Finally, an example application for a waste rock dump illustrates this methodology.

Authors: Concilio Simona , Sessa Lucia , Petrone Anna Maria , Porta Amalia , Diana Rosita , Iannelli Pio , Piotto Stefano
Published: May 2017

Some novel (phenyl-diazenyl)phenols (3a–g) were designed and synthesized to be evaluated for their antimicrobial activity. A previously synthesized molecule, active against bacteria and fungi, was used as lead for modifications and optimization of the structure, by introduction/removal or displacement of hydroxyl groups on the azobenzene rings. The aim of this work was to evaluate the consequent changes of the antimicrobial activity and to validate the hypothesis that, for these compounds, a plausible mechanism could involve an interaction with protein receptors, rather than an interaction with membrane. All newly synthesized compounds were analyzed by 1H nuclear magnetic resonance (NMR), DSC thermal analysis and UV-Vis spectroscopy. The in vitro minimal inhibitory concentrations (MIC) of each compound was determined against Gram-positive and Gram-negative bacteria and Candida albicans. Compounds 3b and 3g showed the highest activity against S. aureus and C. albicans, with remarkable MIC values of 10 µg/mL and 3 µg/mL, respectively. Structure- activity relationship studies were capable to rationalize the effect of different substitutions on the phenyl ring of the azobenzene on antimicrobial activity.

Objetivamos neste estudo problematizar o uso do diário de bordo como auxiliar no desenvolvimento da alfabetização científica dos estudantes, podendo dar suporte a um processo investigativo, relacionando-o com a proposta de aprender a aprender e com a pesquisa na educação básica. Trata-se de uma pesquisa qualitativa, de cunho exploratório, descritivo. Foi desenvolvida em uma escola estadual do município de Macapá/AP, com uma turma de estudantes do 7º ano do Ensino Fundamental, no período de março a junho de 2014. Os estudantes em grupos desenvolveram projetos de pesquisa e registraram as etapas em diários de bordo, os quais foram analisados descritivamente durante e ao final do estudo. As análises dos registros nos diários de bordo, os questionamentos durante as aulas de Ciências e as observações do professor mostram que houve o desenvolvimento da autonomia dos envolvidos na investigação, com a busca por respostas, construção de modelos e protótipos, discussões e questionamentos reconstrutivos, que são indícios da alfabetização científica.
Técnica quirúrgica para reparar la diástasis de rectos asociada a hernia umbilical. Diez años de experiencia
Authors: Bezama Murray José Alfredo
Published: May 2017

Introducción. Las hernias umbilicales suelen estar acompañadas de una marcada diástasis de rectos abdominales. La reparación de estos dos problemas mediante una sutura simple tiene una alta tasa de recurrencia y precisa de una incisión no asumible desde un punto de vista estético. En la bibliografía publicada apenas existe documentación fiable sobre esta entidad. Material y métodos. Entre enero de 2006 y enero de 2016, 36 pacientes con hernia umbilical y diástasis de rectos concomitante se sometieron a reconstrucción de la línea alba, utilizando una técnica personal a través de una pequeña incisión supraumbilical y reconstrucción con malla preperitoneal, sin uso de equipos o accesorios endoscópicos. Los pacientes comprendían 32 mujeres (88.8 %) y 5 hombres, con una media de edad de 36 años (rango: 26-64 años). Resultados. El tiempo de quirófano medio fue de 30 minutos. Todos los pacientes fueron dados de alta en el día de la operación, sin haberse encontrado complicaciones intraoperatorias ni morbilidad posoperatoria, a corto ni largo plazo. La eficacia del procedimiento a 1 año de seguimiento fue del 100 %, tanto para la hernia umbilical como para la corrección de la diástasis. Conclusión. La técnica que se presenta es un nuevo procedimiento que puede considerarse como mínimamente invasivo para reparar las hernias umbilicales asociadas con diástasis de rectos, al no precisar de equipo endoscópico ni modificar el acceso simple de una hernia umbilical simple. La reconstrucción de la línea alba supraumbilical mediante abordaje abierto preperitoneal es una opción sencilla, barata y eficaz para restaurar la anatomía normal de la pared abdominal medial.

Con el incremento en la realización de trasplantes hepáticos como tratamiento de elección en pacientes con insuficiencia hepática, no es infrecuente encontrar candidatos al trasplante que tengan historia de laparotomías y que hayan desarrollado hernias incisionales. Se ha comunicado el tratamiento exitoso de las hernias umbilicales al mismo tiempo que se realizan los trasplantes hepáticos; sin embargo, no existen publicaciones en la bibliografía que hablen del tratamiento de las hernias incisionales complejas en el mismo tiempo quirúrgico que los trasplantes hepáticos. En este trabajo incluimos dos pacientes con hernias incisionales complejas e insuficiencia hepática que se sometieron a trasplante hepático y reconstrucción de pared abdominal mediante la técnica de separación de componentes preservadora de perforantes en el mismo tiempo quirúrgico. Ambos pacientes desarrollaron hemorragia transitoria de la pared abdominal en el segundo día posoperatorio, pero se recuperaron sin conplicaciones. El seguimiento a dos años en ambos casos muestra una adecuada función hepática, y ninguno de los dos ha desarrollado recurrencia del defecto herniario. La reconstrucción inmediata en un solo tiempo de la pared abdominal mediante la técnica de separación de componentes preservadora de perforantes es viable una vez que se ha completado el trasplante hepático en pacientes con insuficiencia hepática. Para alcanzar resultados exitosos en este escenario tan complejo deben tenerse cuidados especiales, particularmente con respecto a la posibilidad de hemorragia posoperatoria temprana.
Interventionless Reservoir-Isolation Valve Removes Need for Intermediate Completion
Authors: Wilson Adam
Published: May 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 184706, “Interventionless Reservoir-Isolation Valve Removes the Requirement for an Intermediate Completion: A Case Study,” by Andrew Edwards, SPE, Euan Murdoch, SPE, and Christopher Munro, SPE, Weatherford, prepared for the 2017 SPE/IADC Drilling Conference and Exhibition, The Hague, 14–16 March. The paper has not been peer reviewed.

This paper focuses on the application of radio-frequency-identification (RFID) technology to enable an operator to eliminate an intervention run (or intermediate liner) for a 10,000-ft reservoir section. The case-study well has preperforated liner in two zones isolated with swellable packers and pressure-actuated annulus packers. The typical procedure is to straddle the annulus packers individually using an inflatable plug, but setting the lower annulus packer incurs additional risk while running in the horizontal for an extended distance. Here, an RFID-actuated reservoir-isolation valve (RIV) eliminates an intervention run.

Methodology

RFID is now a common technology used across various industries to provide a means of communication between a passive antenna and an active antenna. This technology has now been adapted and applied to actuate downhole tools in oil and gas wells.

In the RFID portfolio, the installed equipment houses the active antenna and RFID tags that are deployed at surface and provide the passive antenna. The tool provides a secure, pressure-resistant encasement for the electronics required. The RFID tag contains a memory bank to store a command that is programmed at surface and a coil that takes power from the radio-frequency field generated by the active tool antenna. This power provided by the active antenna is passed directly to the passive antenna and allows the tag to transmit the programmed command to the RFID tool. The command is then decoded and processed within the tool and then acted upon. The command can include logic to tell the tool to function immediately, function after a delay, or switch operating modes to look for another trigger.

The small size of the tag allows freedom of movement and easy integration with existing completions. Because RFID transmission is a close-proximity means of transferring data, it requires no direct contact between both devices. The communication can be made in a downhole context at up to 6 to 12 in.

RFID technology has so far been used in drilling applications, in upper-completion equipment, and in the reservoir as an inflow-control-device sleeve or for providing a multizone stimulation sys-tem in slickwater or hydraulic proppant.
Technology Focus: History Matching and Forecasting (April 2017)

Technology Focus

The initial work on computer techniques for assisted history matching date back to the 1960s. However, it was a long journey between the development of early methods and operational use. Initially, these methods were referred to as “automatic history matching,” giving the wrong impression that it was something we could delegate to a computer. Fortunately, industry and academia soon realized that “assisted” was a more accurate term than “automatic.”

Nowadays, there is an impressive amount of literature and a large number of assisted-history-matching methods. The diversity is so vast that it is challenging to divide these methods into categories. For example, there are several flavors of methods based on sensitivity and gradient-optimization algorithms. There are also methods grounded on stochastic optimization, evolutionary algorithms, design of experiments, proxy modeling, streamline simulation, and Kalman filters. This is just to mention a few, and the list is still growing.

Regardless of the specific method of your choice, I believe the main development in history matching is the recognition that it can be formulated as a Bayesian inference problem. Bayes’ rule provides an elegant framework to formalize the process of learning from data to update our beliefs. The beauty is in the fact that Bayes’ rule gave to history matching the correct meaning. History matching is no longer a searching process to find the best model. Instead, history matching is a process of mitigating uncertainty in light of new information.

The papers summarized in this feature and the ones indicated in the additional-reading list are excellent examples of recent developments and applications of assisted-history-matching techniques. All are aligned with the modern Bayesian interpretation. I hope you enjoy the reading.
