Competencia social en niños y adolescentes de la ciudad de Bucaramanga (Colombia) según escala Messy
Authors: Serrano Mora Sandra Milena , Marín Rodas Claudia Marcela 
Published: March 2017

Muchas de las problemáticas de violencia e intolerancia están asociadas al déficit de mecanismos que permitan al individuo desenvolverse eficazmente, por ende se intentan buscar herramientas de relevancia social que permitan definir los factores que moldean estos comportamientos con el fin de elaborar metodologías para desarrollar técnicas enfocadas hacia las competencias asertivas que refuercen estas características individuales en cada sujeto. Es por ello, que este artículo de investigación se enfocó en identificar los componentes de la competencia social con los que cuentan los niños y adolescentes de Bucaramanga y la relación con sus características demográficas (edad, nivel educativo, estrato socioeconómico). Se planteó un estudio cuantitativo, de corte transversal correlacional. La muestra fue por conveniencia, con un total de 330 participantes con edades entre 8 y 17 años. Se aplicó la escala Messy y el análisis de resultados se llevó a cabo a través de SPSS. Los resultados obtenidos muestran que no se puede definir una relación directa entre las competencias sociales que posee un individuo y sus datos sociodemográficos, corroborando la influencia de otros factores multivariados en su desarrollo.
La intervención del CICR en la protección de la dignidad de las víctimas militares y de policia en el conflicto armado con las FARC en Colombia
Authors: Rojas Jairo 
Published: March 2017

Los numerosos conflictos armados que vive el mundo, demandan un análisis constante y permanente de las acciones de los organismos internacionales que de una forma u otra cumplen un papel determinante en la comprensión y asistencia de los diferentes actores de los enfrentamientos bélicos, esto de cara a un conflicto armado interno que vive Colombia entre las Fuerzas Armadas del Estado y las FARC. El presente artículo, resume una investigación especificada dentro de un tipo de estudio descriptivo - analítico, con un análisis de tiempo retro - prospectivo, dentro de un universo y muestra que son los informes anuales del CICR para Colombia 1998 - 2010, en la que se analizan las acciones del Comité Internacional de la Cruz Roja en Colombia, durante el período comprendido entre 1998 y 2010, respecto de las actuaciones del comité referidas a la protección de los Derechos Humanos de los miembros de las Fuerzas Armadas de Colombia y de sus familias. Su objetivo principal es plantear una propuesta de intervención del accionar del CICR, para la protección de la dignidad de las víctimas del conflicto armado con las FARC, en el estado Colombiano, para que así se propenda por la protección de los miembros de las Fuerzas Armadas de Colombia en procura del respeto de los Derechos Humanos. Finalmente, tras el desarrollo de la presente investigación, se resalta el hecho de no haberse evidenciado un patrón equitativo en la atención de las víctimas del conflicto armado con las FARC, entre las víctimas civiles no vinculadas a la Fuerza Pública y las que sí pertenecen a la Fuerza Pública, reflexiones que son ampliadas en las conclusiones del presente artículo de investigación.
Elementary Teachers’ Perspectives on the Use of Multicultural Literature in Their Classrooms
Authors: Mongillo Geraldine , Holland Karen F. 
Published: March 2017

This qualitative study set out to determine how multicultural literature was used and perceived by US elementary school teachers, and how the beliefs of teachers shape perceptions, selection, interpretation, and the teaching of multicultural literature (Ketter & Lewis, 2001).Twenty-six (26) elementary school teachers across the country responded to this study. An invitational email with a web-survey hyperlink was utilized. Variables pertaining to participant background, definition, selection acquirement and application of “multicultural” literature, the elementary school community and district mandates were addressed in the web survey. Findings revealed that all participants used multicultural literature sometime during the school year. The majority of participants were Caucasian females teaching in suburban schools, which did not have a mandated multicultural curriculum. Regardless of mandates, the majority applied a “narrow” definition for multicultural literature using the words “cultural”, “race,” and “nationality.” Other findings indicated that elementary school teachers used multicultural literature more frequently when they had strong administrative support, regardless of their students’ or their own ethnicity.

Published: March 2017

Abstract
Nanoparticles applications in the petroleum industry have grown significantly recently especially for EOR, and waterfloding. Although the nanoparticles are small, they can be retained in the porous media by different mechanisms (i.e. surface deposition, and plugging of pore throat either by single or multi-particles). The objective of this paper is to develop a mathematical model capable of capturing the different damage mechamisms and the associated permeability impairment. We introduce a mathematical model that combines Darcy and convection-diffusion equation to describe fluid flow, and nanoparticles transport and interaction in porous media. Pore throat size distribution is used to characterize pore-scale heterogeneity. Permeability field is generated as a function of the pore throat size distribution. Pore throat size and permeability distributions are dynamic functions of nanoparticles deposition and plugging. The mathematical model is solved on a two-dimensional domain using finite difference. The model was matched with experimental data to obtain the model parameters. The model shows that each of the three damage mechanisms can be dominant at specific conditions. The preliminary numerical results demonstrate that concentration and injection rate are the key factors that control the degree of formation damage. These parameters should be optimized to reduce the formation damage associated with nanoparticles transport in porous media. Mathematical modeling along with experimental studies can help to optimize the nanoparticles systems to minimize formation damage.
Integration of Geomechanical Models Optimized Designs Fracture, for the Reactivation of Yacimiento Eocenofract B2X68, Maracaibo Basin
Authors: Barrios Jorge 
Published: March 2017

Abstract
The EoceneFrac area corresponds to a subsoil extension of approximately 230 Km2, located northeast of Lake Maracaibo in the Lagunillas area, where Informal Members B-2-X and B-3-X have been defined as The main oil-producing sands of the Misoa Formation of the Eocene Age, classifying the B-2-X-68 deposit as the second at the western level in crude oil reserves and object of this study. The EoceneFrac reservoir is 24 ° API hydrocarbon and this reservoir is currently the second largest reservoir in the western region. Work on this site began in 1927 and is noted for the fact that it has to be fractured due to its low permeabilities, despite being a shallow production zone. The first fracture occurred in 1959 at the well Years later was the discoverer.
It has a significant consolidation, which aggravates the problem of the low fluidity of the hydrocarbons to the intermediations of the well, the deposit currently has forty-nine (49) wells of which are in different states being active sixteen (16), inactive six (6), abandoned seven (7), three (3) waiting for abandonment and finally seventeen (17) waiting for reconditioning works for the date of January 13, 2013, being the main problem affecting the production of these wells the low mobility.
A Geomechanical study focused on optimizing the fracture designs that arose due to the failed behaviors that had been previously carried out in the B2-X-68 deposit, ceased to function shortly after being made, it is noteworthy that they were found Important parameters of rock and proppant resistance that have a direct impact on collapse of the rock, as well as geopresiones that were not taken into account for initial designs.

Published: March 2017

Abstract
The Shushufindi field is the largest oil accumulation (3.8 billion barrels) in the Oriente Basin in Ecuador, and it represents 16% of the total oil production in the country. It was discovered in 1972 and has achieved a current recovery of 1.2 billion barrels of its original oil in place. Its peak oil production was 125,000 BOPD, reached in 1986; since then the production steadily declined. The Ecuadorian government recognized the danger of declining oil revenues, and, in January 2012, the national oil company (EP Petroamazonas) signed a 15-year Specific Integrated Services Contract with Consorcio Shushufindi S.A. (75% Schlumberger, 25% Tecpetrol).
During an aggressive optimization campaign performed in the last 10 months, the Consorcio Shushufindi has achieved an incremental recovery of 1.1 million barrels (4,400 BOPD) by rebalancing and optimizing bottomhole flowing pressure over most of the field through increasing the extraction rate. An additional 1.1 million barrels (4,700 BOPD) of production was achieved by performing Electrical Submersible Pump (ESP) upsizings in 24 wells, from a complete portfolio of 34 wells.
The Shushufindi revolution demonstrates how an ambitious optimization plan, multidisciplinary integration and collaboration between the operator and the service company can be successful in a mature field despite the associated risks. In addition, this project demonstrates that activities can be performed to increase production at a minimal cost and how to maximize the return on existing assets through the realization of their production potential.
Streamlines Versus Conventional Simulation for Complex and High Resolution Models
Authors: Ursule J. P. , Farina Saint Selve E. A. 
Published: March 2017

AbstractThe aim of this work is to evaluate the desirability of conducting the History Matching using flow lines instead of traditional simulation. The results are very encouraging. The simulation time was reduced to a 10% from its original value, with a very good match. This was subsequently confirmed with a traditional simulation.The San Jorge basin (CGSJ), located in southern Argentina, extends over the central part of the Patagonian region. The sedimentary fill of the basin is related to different rift and sag tectonic phases, from Triassic to Cretaceous. During Late Cretaceous-Early Tertiary, a marine transgression from the Atlantic developed. Tertiary sediments completed the basin fill. Sediments from continental rivers form a huge overlying of fluvial-shallow lacustrine units deposited under late sag conditions. These units contain the reservoirs that host the hydrocarbon accumulations of the basin. The study area to be developed by Secondary Recovery has more than 250 reservoirs and 300 drilled well. The drenage radio is about 150 mts. The average production of each well is around 15 Bbl/d.As part of the Reservoir Caracterization, a high-resolution reservoir model was build. The model contains 5.4 million cells (1.1 are active) with 290 producing layers and 260 wells. Production started mid 1993 (22 years of History). Water flooding started 2002 when 21 wells were converted to injectors. It's a simple grid with 50 to 50 meters by cell. A conventional simulation run takes 12 hours. No assisted history matching was possible, due to the size of the model. With the use of a fast flow simulation technique, streamlines, the time was reduced to 2.5 hours. This makes possible to work over the simulation parameter. With this normal simulation time, enough runs were done to match pressure behaviors and field productions. So, a standard history matching workflow was used with the exception of flow lines to perform the simulation runs.The use of stream lines reduced nine times the standard simulation time. Thanks to this, it was possible to manually iterate the model parameters, doing each time a new simulation run to evaluate results. This work methodology allowed the correct understanding of Reservoir drainage mechanism. With all this, history match was done in a reasonable time. The absolute difference in liquid production was less than 12%. Finally, a conventional run was performed to verify the consistency between the two methodologies. In this case, the difference between both runs is imperceptible. This confirms that the use of strem lines is an excellent tool to adjust big size models.
Channel Fracturing Long Term Evaluation Shows Increased Recovery Rate, San Jorge Gulf Basin, Argentina

Abstract
The objective of this work is to describe the productivity obtained through the use of Channel Fracturing technique in a conventional reservoir characterized by its stratigraphic complexity, isolated sandstone bodies of low thickness, low volume, lenticular geometry, moderate reservoir rock quality and high tobaceous content.
Channel Fracturing (Gillard et al, 2010) began to be used in Argentina in 2011-2013, both in conventional and non-conventional wells. It provided significant benefits in costs and logistics during the initial period of Vaca Muerta development because of the reduction the proppant and the liquid required by the method.
This technique generates a network of open channels within the proppant pack, providing highly conductive paths to recover fracturing fluid residue and subsequently produce hydrocarbons. The improvement in well productivity in unconventional was shown in SPE Completion of the Eagle Ford Formation with Heterogeneous Proppant Placement (SPE149390).
The case study corresponds to the Pampa del Castillo-La Guitarra Field, operated since 2001 by Enap Sipetrol Argentina S.A., located on the North Flank of the San Jorge Gulf Basin (Chubut-Argentina) 50 km west of the city of Comodoro Rivadavia
A comparison of the productivity, of the same level, was made in wells fractured by both Channel Fracturing, and conventional fracture and without fracture. Fracture simulation models were performed and the results obtained using the two techniques were compared. Such a comparison shows that Channel Fracturing stimulation provides greater connected surface. Despite the reduction of the proppant by 40 to 50%, when using Channel Fracturing, production monitoring indicates a decrease in the decline liquid rate compared to conventional hydraulic fractures.
Due to the results obtained, this technique started being use in other wells (22 wells to November 2016) of the field with satisfactory results in production increase.
Study and Simulation of Matrix Acidizing in Sandstones Reservoirs Applied to Injection Wells of the Mature Fields

Published: March 2017

Abstract
There are several techniques for estimating rocks, one of which is matrix acidizing. Aiming at the recovery of non-reservoir hydrocarbons, from the acidification process, the study of the mineralogical composition of formation, the banks are dissolved in the selection of acids by means of their permeability. By proposing an improvement of the flow in the production of the region of the well
When production in the well begins to fall, it enters the mature field phase, the one whose oil and natural gas reservoir, after primary production, still holds some of its resources in situ. It is necessary to carry out a modeling study to predict the volume and the injection rate in sandstone formations. The methodology will be used for models of two minerals, with a fast and slow dissolution nature.
Non‐traumatic orbital haemorrhage as a complication of emergence from anaesthesia
Authors: Sharma Neharika , O'Hagan Stephen 
Published: March 2017

SummaryWe present the case of a 54‐yr‐old female who awoke following general anaesthesia with a right‐sided non‐traumatic spontaneous orbital haemorrhage and was subsequently discovered to have an underlying orbital cavernous haemangioma. Spontaneous orbital haemorrhage following emergence from anaesthesia is rare.The occurrence of non‐traumatic spontaneous orbital haemorrhage associated with general anaesthesia requires urgent assessment for compressive optic neuropathy, and investigation with computed tomography (CT) or magnetic resonance imaging (MRI) for evidence of underlying orbital venous anomalies, such as an orbital varix, cavernous haemangioma, or lymphangioma.
Predicted impossible mask ventilation in a patient with giant rhinophyma
Authors: Bennett James , Webb Philippa , Ahmad Imran , Hopkins Claire 
Published: March 2017

SummaryWe describe the safe management of a patient with a giant rhinophyma requiring surgical debulking of the nasal tumour. Anaesthetic management incorporated an awake fibreoptic intubation (AFOI) as an effective facemask seal, and therefore bag/valve/mask ventilation, was predicted to be unachievable. We suggest that this is the safest approach to maintain oxygenation when difficult facemask ventilation is anticipated post anaesthetic induction.

‘Silver bullet’ overdose: the use of dantrolene to treat benzylpiperazine toxicity
Authors: Johnston David 
Published: March 2017

SummaryThe number of deaths due to benzylpiperazine toxicity amongst young adults in Northern Ireland and Scotland is increasing, compounded by the growing accessibility to herbal high medication. This case highlights the dangers posed by benzylpiperazine‐containing ‘party pill’ herbal high recreational agents. Life‐threatening serotonin syndrome resulted in profound central nervous system, haemodynamic and metabolic instability. In the absence of cyproheptadine, dantrolene was successfully used to manage serotonin syndrome although this is not a universally accepted or scientifically proven treatment. Supportive care remains the mainstay of acute management.
Traumatic rupture of a nasoethmoidal meningoencephalocele in an adult following a difficult airway scenario
Authors: Langley Adrian , Lai Nai An , Flynn Christopher 
Published: March 2017

SummaryIntranasal meningoencephaloceles are characterised by protrusion of brain and meninges through a skull‐base defect. Nasal intubation or instrumentation may lead to complications such as meningoencephalitis and cerebrospinal fluid rhinorrhoea or fistula formation. A 62 year old lady developed rhinorrhea following failed videolaryngoscopic and nasal fibreoptic intubation, which ultimately necessitated emergency surgical tracheostomy for a “can't intubation can't ventilate” scenario. This case highlights the diagnosis and management of an unusual complication resulting from difficult airway management.
Takotsubo (Stress Induced) Cardiomyopathy triggered by laryngoscopy
Authors: Lambe Rachel , Allman Louise 
Published: March 2017

SummaryTakotsubo Cardiomyopathy is an unpredictable but important condition that mimics acute coronary syndrome. Although the exact pathogenesis is unclear, most cases appear to be initiated by a stressful event, either physical or emotional. In the case described laryngoscopy was thought to be the triggering factor. Cases can be associated with ischaemic changes on the ECG and a rise in troponin levels. The characteristic appearance on echocardiography of an akinetic apical ventricle wall and normal coronary arteries on angiography confirms the diagnosis. Short‐term outcome is excellent, with most reported cases showing complete resolution of the abnormalities seen on echocardiography and any associated left ventricular dysfunction.
