Published: September 2019

Objectives. To demonstrate a flexible and practical method to obtain near real-time estimates of the number of at-risk community-dwelling adults with a chronic condition in a defined area potentially affected by a public health emergency. Methods. We used small area estimation with survey responses from the 2016 Behavioral Risk Factor Surveillance System together with a geographic information system to predict the number of adults with chronic obstructive pulmonary disease who lived in the forecasted path of Hurricane Florence in North and South Carolina in 2018. Results. We estimated that a range of 32 002 to 676 536 adults with chronic obstructive pulmonary disease resided between 50 and 200 miles of 3 consecutive daily forecasted landfalls. The number of affected counties ranged from 8 to 10 (at 50 miles) to as many as 119 to 127 (at 200 miles). Conclusions. Community preparedness is critical to anticipating, responding to, and ameliorating these health threats. We demonstrated the feasibility of quickly producing detailed estimates of the number of residents with chronic conditions who may face life-threatening situations because of a natural disaster. These methods are applicable to a range of planning and response scenarios.
Surgical Treatment of Pelvic Discontinuity
Authors: Szczepanski Jason R. , Perriman Diana M. , Smith Paul N. 
Published: September 2019

Background:
Pelvic discontinuity is a rare condition that is treated with a range of implant constructs. However, surgical failure rates are high, and outcome data are inconsistent. It is therefore difficult to gain a clear picture of whether recently developed constructs (antiprotrusio cage [APC], cup-cage, custom triflange, and porous metal) provide better outcomes in terms of mechanical failure and complications in the short to long terms. This study investigated the failure and complication rates associated with cage constructs and porous metal technologies.

Methods:
A systematic review and meta-analysis were performed according to the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines to evaluate the studies showing pelvic discontinuity in revision total hip arthroplasty. Data retrieved included the intervention performed, length of follow-up, mechanical failure, and other complication rates (dislocation, infection, neurological, loosening, migration). Study quality was assessed with the Methodological Index for Non-Randomized Studies (MINORS) instrument. Pooled mechanical failure and complication rates were calculated using MetaXL 5.3.

Results:
None of the included 30 articles (n = 585 hips) were of high quality. The meta-analyses revealed a mechanical failure rate of 14% for all constructs combined. Custom triflange (5%) and cup-cage (7%) had the lowest mechanical failure rates compared with the commonly used APC (25%) and porous metal (12%). The overall other complication rate was 28%, with cup-cage lower at 21% compared with APC (34%) and custom triflange (28%). Long-term evidence investigating both interventions and porous metal technology is limited.

Conclusions:
Mechanical failure rates for cup-cage and custom triflange were lowest. The other complication rate for cup-cage was lower than the pooled average. The study quality was limited, indicating a need for better studies and/or a registry.

Este artículo de investigación tiene por objetivo estimar los factores determinantes de la innovación en instituciones de educación superior (IES) de Colombia en el período 2014 – 2015, mediante la utilización de un modelo Logit Multinomial Ordenado, en el que se categorizan de manera ordenada los tipos de innovación considerados por el DANE (Departamento Administrativo Nacional de Estadística), donde se asignaron los valores de 0 a las IES que no obtuvieron innovaciones, 1 a las IES que tuvieron la intención de innovar, 2 a las IES potencialmente innovadoras, 3 a las IES que tuvieron innovaciones en sentido amplio y 4 a las IES que obtuvieron innovaciones en sentido estricto.
Para ello, fueron utilizados los datos arrojados por la encuesta de desarrollo e innovación tecnológica, sector servicios y comercio 2014 – 2015, considerando 231 instituciones de educación superior, de tal forma que la estimación realizada fue poblacional y no muestral.
Así mismo, fueron categorizadas en tres grupos las variables independientes: esfuerzo innovador, apalancamiento externo y obstáculos de la innovación. Se encontró que en su mayoría estas variables son significativas y acordes a la relación establecida en la hipótesis de estudio.
Finalmente se estableció la probabilidad de evento que tiene cada tipo de innovación en una IES representativa para Colombia, y los impactos que tienen los factores determinantes de la innovación en cada categoría de innovación.

Contribuir en la construcción del estado del arte del emprendimiento femenino en Colombia fue el propósito del proyecto, cuyos resultados se exponen mediante este artículo, el cual presenta una revisión documental que inició con la búsqueda general de términos a través del tesauro emprendimiento femenino y género usando operadores boléanos y truncadores y que se centró en bases de datos como EBSCO, Redalyc, Dialnet y Scielo.
A través de esta revisión se pudo identificar, entre otros elementos, que existen pocos estudios en el tema de género específicamente, lo que deja en evidencia los vacíos existentes en el conocimiento relativo al emprendimiento femenino. Así mismo, se pudo evidenciar que en el trabajo investigativo sobre este campo se emplean similares diseños metodológicos, que en general se basan en investigación bibliográfica, análisis de casos, análisis cuantitativos y cualitativos y con poca frecuencia, en el uso de software estadístico, para correlacionar las variables involucradas.
Finalmente, fue posible establecer que la investigación en el tema viene enriqueciéndose en la medida que aumenta la presencia de mujeres en cargos directivos, pese a esto, aún hay barreras y estereotipos por superar y por ende se hace importante estudiar esta temática en particular.

El objetivo de esta investigación fue determinar cómo se asocian los factores que influyen en la intención emprendedora (IE) en Colombia y cuáles de ellos resultan de mayor relevancia. La investigación realizada fue de tipo descriptivo y tiene alcance correlacional. El trabajo se fundamenta en la Teoría del Comportamiento Planeado y se adicionan variables socioeconómicas y la facilidad para hacer negocios según el Doing Business.
Para ello se aplicó un instrumento de recolección de información a una muestra de 485 estudiantes de 36 programas de Maestría en Administración en Colombia; los datos se procesaron mediante dos métodos estadísticos: Análisis de Correspondencias Múltiples (ACM) y Regresión Logística (RL).
Este análisis posibilitó establecer nueve factores que determinan la IE de los estudiantes de Maestría en Administración en Colombia, de los cuales tres corresponden a normas sociales, dos son actitudes, dos pertenecen a control del comportamiento y dos atañen a aspectos socioeconómicos.
Así mismo, se encontró que, según el ACM, las personas con mayor IE están relacionadas con ciudades que tienen facilidad alta y media para hacer negocios; esta relación puede tener asidero en el hecho de que las poblaciones en las que es más fácil crear empresas tengan un contexto más apropiado que facilita la actividad emprendedora.
Se concluye entonces que una mayor intención emprendedora se encuentra determinada por la combinación de este conjunto de variables, que en orden de importancia corresponden a normas sociales, actitudes y control de comportamiento, unidas a algunos aspectos socioeconómicos.

Esta pesquisa teve como objetivo identificar estratégias pelo Observatório Social de Sorriso (OSS-MT), Mato
Grosso, Brasil, para atrair recursos financeiros durante o período de 2010 a 2015. Este estudo caracteriza-se por uma abordagem qualitativa, exploratória e de estudo de caso. Para coleta de dados se aplicaram entrevistas semiestruturadas, com um total de seis perguntas abertas e quatro fechadas. Estas entrevistas foram realizadas em três gerentes que estiveram à frente durante o período de 2010 a 2015 e, em
seguida, foi utilizada a análise de conteúdo.

s resultados permitem identificar que a instituição não é suficientemente conhecida pela pouca divulgação, o
que pode constituir um obstáculo à captação de recursos. Os resultados também mostram que, nos três períodos de gestão foram aplicados, em geral, as mesmas estratégias de captação de recursos: visitas a empresas para divulgação do trabalho; transparência financeira para a sociedade; relacionamento com potenciais doadores e participação em eventos e conferências, e apenas um dos gerentes se preocupou em aderir uma nova estratégia para arrecadar fundos a curto prazo, a venda de selos, indicando a necessidade de profissionalização organizacional e o desenvolvimento de estratégias inovadoras para a consecução dos objetivos e viabilidade dos resultados.

Evaluation of Surfactant Application to Increase Oil Recovery in Bottom Aquifer-Driven Naturally Fractured Reservoir
Authors: Alakbarov Samir , Behr Aron 
Published: September 2019

Abstract
As means of primary and secondary recovery, the fractured reservoirs with strong aquifer can be developed either by water injection or by utilizing the natural energy of the aquifer itself. High permeability contrast between fracture and matrix blocks and preferably mixed to oil-wet nature of the naturally fractured reservoirs makes waterflooding and primary methods of production mostly inefficient leaving vast amount of oil unrecovered in the oil-bearing matrix blocks. Due to the absence of a sufficient pressure gradient, wettability of the reservoir rock determines the rate of the displacing fluid invasion into the matrix blocks by capillary and gravity forces. Chemical Enhanced Oil Recovery (cEOR) mechanisms are aimed to intensify oil recovery by affecting these forces. Laboratory and field pilot tests showed the application of surfactant to be a promising cEOR agent for increasing oil recovery from the matrix blocks, both in water-wet and oil-wet fractured reservoirs. For the case studied in this paper, analysis of the surfactant application in the fractured reservoir required the solution of the following challenges: –Interpretation and reproduction of the EOR mechanisms by mathematical modelling–Adaptation and integration of the EOR effects into the full field model–Development of the proper technology for surfactant injection under the given reservoir conditions
The aim of the paper is to present the discussions and the workflow for analyzing and identification of the surfactant application in the fractured reservoir with strong bottom driven aquifer.
Introduction of the trapping number (accounting the capillary and Bond numbers) as a scaling parameter enabled to evaluate the combined effect of capillary, viscous and gravity forces on oil desaturation. To integrate the trapping number into commercial simulator, a special interface was developed within the scope of this work. The EOR effects of surfactant were evaluated on the single porosity numerical models representing a discretized matrix block.
To upscale the specific recovery mechanism as a mass exchange term into full field dual porosity model a special coupling solution was introduced. A pseudo-capillary pressure is suggested as an intermediate function to translate the recovery mechanism from single to dual porosity model.
The developed innovative technology proposes a special injection and production strategy for more effective areal sweep efficiency as well as alteration of injection water chemistry to drive the surfactant into target areas without high losses into the aquifer.
This technology and the described workflow, both were employed for advanced estimation of surfactant EOR potential in a naturally fractured carbonate reservoir. The surfactant aided recovery mechanism based on transition from capillary to gravity dominated displacement showed enhanced effect on ultimate oil recovery from this reservoir.
Robust Characterisation Methods of Cuttings Derived from Siliciclastic Reservoir and Seal Rocks - A Case Study from New Zealand

Published: September 2019

Abstract
Even though coring of rocks is the best way to characterize reservoir and source rocks geologically and petrophysically, this method is considered expensive, having a relatively high cost per foot. Alternatively, side-wall cores and cuttings are widely used in reservoir characterization at a relatively low cost. However, this method has limitations related to cuttings bad physical conditions, size, mixed lithological and mineralogical characteristics which make the commonly used conventional evaluation methods not applicable. This study introduces a robust combination of digital and conventional core analysis methods to overcome these limitations and characterize reservoir and shale cuttings derived from two hydrocarbon-bearing formations in New Zealand.
Initially, all cuttings from both formations were screened based on their cutting sizes and later based on the visually observed textures using the stereomicroscope. This helped in selecting representative cuttings for the main identified textures. These cuttings were CT imaged at a resolution ranging from 40 to 4 microns/voxel resolution in order to confirm their rock textures and sedimentary structures for better characterization results. Next, mercury injection capillary pressure (MICP), X-ray diffraction (XRD), and petrographical analysis were conducted on all selected cuttings with different rock textures in order to understand the pore types, textural variations, diagenetic overprints and mineralogy of the cuttings samples. Then, they were scanned at optimum resolutions using Micro CT and 3D FIB-SEM microscopies. Finally, all acquired images were segmented digitally and 3D rock volumes were created. These volumes were used in computing porosity, permeability, formation factor resistivity (FRF) and poroperm trends digitally using numerical simulation techniques.
Conventional and digital rock analysis showed that the cuttings derived from the reservoir interval are composed of an argillaceous sandstone with a very good computed porosity (18% up to 31%) and permeability (30 to 200 mD). On the other hand, the cuttings derived from the shale source rock interval, which were predominately composed of clay minerals, have a computed porosity of 12% to 13% (mainly inorganic pores) and an absolute permeability in the range of 0.5 to 4 Micro-Darcy. The digital poroperm trend analysis identified distinct poroperm trends for each formation which helped in understanding their petrophysical aspects.
This integration between conventional and digital methods provided better geological and petrophysical understanding of both formations using a limited number of cuttings, less cost and time.
Characterization of Channelized Systems in a Carbonate Platform Setting: A Case Study on the Late Cretaceous Reservoir from the Supergiant Oilfield, Iraq

Abstract
Identification of tidal channels fairways is key for predicting behavior of areas at higher risk to water breakthrough or otherwise have a significant impact on the development and monitoring of reservoir performance. However, tidal channels in carbonates are not often easily characterized using conventional seismic attributes. It is important to decipher the complexity of the carbonate tidal channel architecture with integrated multisource data and a variety of approaches.
In this paper, petrological characteristics and petrographic analysis is conducted on well logs and validated carefully using core data. Then, the second step is to compare the carbonate channel systems with modern analogue in Bahama tidal flat and outcrop scales in Wadi Mi'Aidin (Northern Oman). Thereafter, the supervised probabilistic neural network (PNN) and linear regression method were undertaken to detect an additional channel distribution.
The relationship of high porosity with low acoustic impedance appeared mostly in the channel facies which reflects good reservoir quality grainstone channels. Outside these channels, the rock is heavily mud filled by peritidal carbonates and characterized by a high acoustic impedance anomaly with low quality of porosity distribution. The new observation of PNN porosity volume revealed a lateral distribution of the Mishrif carbonate tidal channels in terms of paleocurrent direction and the connectivity. Additionally, the prior information from core data and the geological knowledge indicate a good consistency with classified lithology. These observations implied that Mishrif channels consist of a wide range of lithology and porotype fluctuations due to the impact of depositional environment.
The work enables us to provide a new insight into the distribution of channel bodies, and petrophysical properties with quantification of their influence on dynamic reservoir behavior of the main producing reservoir. This work will not only provide an important guidance to the development and production of this case study, however also deliver an integrated work path for the similar geological and sedimentary environment in the nearby oil fields of Southern Iraq.
