La especialidad de las misiones que constitucionalmente le han sido encomendadas a las Fuerzas Armadas y a sus miembros, así como la singularidad de los destinos del personal militar, con frecuentes cambios de localidad de manera forzosa, hacen que, de manera habitual, se vean obligados a residir fuera de su domicilio familiar. Es por este motivo, por el que en numerosas ocasiones los militares desarrollan su privacidad bien en cuartos habilitados en las propias unidades, centros u organismos militares, en residencias militares gestionadas por directores con empleo militar y dependientes del Ministerio de Defensa o en períodos de ejercicios, maniobras o misiones, dentro o fuera del territorio nacional, en tiendas de campaña, barracones, o buques. De esta manera, podemos observar, como se amplían considerablemente los lugares en los que los miembros de esta institución, desarrollan su vida privada, lo cual a su vez, genera problemas de determinación en torno a cuáles de estos lugares pueden incluirse en el concepto de domicilio constitucionalmente merecedor de protección, especialmente a los efectos de la realización de entradas y registros.

AbstractMedical educators are recognizing that social accountability is a tenet of Canadian medical education, yet it is a difficult concept to teach didactically. Accumulating evidence supports the integration of social accountability into the medical curriculum through community involvement. Fortunately, the University of British Columbia Faculty of Medicine enables students to pursue community learning as part of its curriculum; and we, five medical students, benefited from that opportunity. This commentary will promote the importance of teaching social accountability in medical schools through community-based learning based on available literature and our personal experience with Vancouver’s Downtown Eastside (DTES).

Published: February 2017

Background: Intestinal perforation as a complication of enteric fever is still a serious problem in developing nations. Enteric ileal perforation is associated with high morbidity and mortality and many patients present in a severe toxic state because of delay in diagnosis and late presentation to hospital.Methods: A prospective study was conducted to assess the prognostic factors in enteric ileal perforation. Observations were made regarding symptoms, signs, duration of illness and presentation of patients to the hospital after acute episode. Per operative findings regarding site, size and number of perforations were recorded. Operative procedures were simple closure, ileostomy, or resection of diseased segment including right hemicolectomy done for associated caecal perforation and entero enteric anastomosis. Post-operative complications like wound infection, wound dehiscence, residual abscess, faecal fistula and deaths were documented.Results: There were 50 enteric ileal perforation cases with a age range of 13-80 with a mean age of 30.7. Male: female ratio was 11: 1. 85% of patients presented within 48 hrs of onset of symptoms of perforation and there is significant mortality in patients who presented more than 48 hrs of onset of symptoms of perforation (57.14%). Mortality was high in multiple perforation group (40%) and also higher incidences of fecal fistula and wound dehiscence.Conclusions: Age and sex have no bearing on the outcome. Perforation presentation interval, delay in surgery, number of perforations are important prognostic markers for typhoid ileal perforation.
Environmental Tobacco Smoke and Periodontitis in United States Non‐Smokers, 2009 to 2012
Authors: Sutton Julie D. , Salas Martinez Mabel L. , Gerkovich Mary M. 
Published: February 2017

Background: Epidemiologic studies using half‐mouth designs for assessment of periodontal disease prevalence have reported that environmental tobacco smoke (ETS) exposure of non‐smokers is associated with a two‐ to three‐fold increase in the odds of developing periodontitis. In response to the possibility of under‐reporting of periodontitis, the Centers for Disease Control updated periodontal examination procedures in 2009 for the National Health and Nutritional Examination Survey (NHANES), including full‐mouth, six‐site periodontal probing, and attachment loss assessment. Aims of this study are to estimate prevalence of periodontitis among United States non‐smoking adults exposed to ETS, report the values of the improved methods for estimating disease prevalence, and evaluate the predictive contribution of ETS exposure to periodontitis.Methods: A cross‐sectional study was conducted using NHANES data from the 2009 to 2012 examination cycle. To address these aims, oral examination data were used to determine prevalence of periodontitis among United States non‐smoking adults and to test the influence of ETS exposure on occurrence of periodontitis.Results: There was a 28% increase in the odds of periodontitis for those with any ETS exposure compared with those with no measurable exposure (Wald χ2 test statistic [df] = 6.58 [1], P = 0.01; 95% confidence interval = 1.06 to 1.55).Conclusion: ETS exposure increases the risk of an individual developing periodontitis.
Fault detection using neural network
Authors: Namigo Elistia Liza 
Published: February 2017

<p class="Abstract">Fault detection technique using neural networks have been successfully applied to a seismic data volume. This technique is basically creating a volume that highlights faults by combining the information from several fault indicators attributes (i.e. similarity, curvature and energy) into fault occurrence probability. This is performed by training a neural network on two sets of attributes extracted at sample locations picked manually - one set represents the fault class and the other represents the non-fault class. The next step is to apply the trained artificial neural network on the seismic data. Result indicates that faults are more highlighted and have better continuity since the surrounding noise are mostly suppressed. </p>

Abstract
In recent years, oil and gas production from unconventional resources has been of particular importance in the United States and Canada. In Mexico on the other hand, the current status of shale development still remains in the exploration phase. Nevertheless, despite its incipient evolution, the Upper Jurassic Pimienta shale play has demonstrated very prospective characteristics, particularly because of the type of produced hydrocarbons (i.e. light-oil and NGL's) and the brittle nature of its reservoir rock.
This paper describes the advances in the evaluation of the unconventional Jurassic Oil Play in Mexico. Production test results and descriptive analyses made in terms of their textural, petrophysical, geochemical and mineralogical conditions of this emerging play are presented. Comparison to other producing shale plays is also discussed and reveal encouraging potential.
This work aims to increase the level of understanding of the unconventional Upper Jurassic Pimienta formation that eventually may contribute to Mexico´s oil output. Additionally, the Mexican authority plans to offer shale exploration blocks through an international auction in the future. The content of this paper may help as reference to describe the basic elements of this play.
Coupling Analytical and Numerical Methods to Assess Performance and Stimulation Efficiency in Multi-Stage Fractured Horizontals
Authors: Yu Shaoyong , Rezk Claude 
Published: February 2017

Abstract
Despite the technological advances in stimulation practices of Multi-fractured-horizontal well (MFHW), many operators (in early-life) still wrestle with the question – "Is it the rock properties or is the stimulation that is impacting my performance?" Addressing this question requires forensic considerations.
From the perspective of rate transient analytics (RTA), the bulk linear flow parameter (LFP) has received much attention in literature as a means of characterizing the performance in MFHW; specifically, in tight rock systems. The most common means of assessing the LFP is via the straight-line approach reconciliation of the rate-normalized (pseudo-) pressure versus square root-time, and time may not necessarily be actual time. Having said that, this a critical step prior to jumping to the square root time plot is to confirm the linear flow regime exists. Best practice is to employ the log-log (specialized plot of the) rate normalized pressure and derivative functions, and confirm that a half-slope is discernible. This approach coupled with the square root time plot bodes the confidence needed for interpretation.
While the bulk Linear Flow Parameter, or the A√K value is a proxy for flow capacity, the constraint is that it cannot uniquely distinguish the quantitative measure of the induced fracture properties from the intrinsic permeability of the rock. Furthermore, it is only an approximate solution with fundamental assumptions and/or required corrections if non-constant diffusivity applies, as well as high-drawdown, multiphase phenomena, exotic diffusion mechanisms and/or compaction effects.
This paper explores the interplay of the individual linear flow parameters by testing various reservoir and stimulation properties via numerical models (i.e. synthetic cases with control variables). The permutations of these tests are reflected via the flow regime signatures observed with the respective LFP and the associated production impacts.
Actual field cases studies are also provided and evaluated analytically to establish consistency and validate the aforementioned observations. The case studies are specific scenarios where production impairment is suspected and could potentially be attributed to stimulation efficiency issues. In other words, field cases are presented where a flow restriction could exist in the respective laterals and the coupled numerical and analytical methods confirm whether milling interventions would or would not necessarily improve production performance.
Permanently Sequester Anthropogenic Carbon Dioxide - Through Hydraulic Fracturing
Authors: Reynolds M. M. , Buendia J. 
Published: February 2017

Abstract
Carbon dioxide (CO2) and other greenhouse gas (GHG) emissions have become a major challenge globally, and particularly for the oil and gas industry. Carbon capture, utilization and storage (CCUS) is one of the options to reduce the amount of anthropogenic CO2 entering the atmosphere. This option creates economic benefit from the waste CO2, vs. pure disposal for sequestration. Organic rich shale reservoirs are an attractive target for carbon storage, due to their adsorptive abilities and multiple mechanisms for gas storage.
CO2 has been widely used in oilfield operations since the 1950's. The unique physical properties of CO2 allow for easy transport in pipelines as a gas, or by transport truck as a cold liquid. Oilfield uses include: a gaseous agent to assist in fluid recovery from the wellbore, a component in hydraulic fracture fluids, an enhanced oil recovery (EOR) agent, a fluid blockage removal agent, etc. CO2 is at least partially soluble in water and is a strong hydrocarbon solvent.
This study investigates the amount of CO2 sequestered when utilized as a component in the hydraulic fracture fluid system used in multi-stage fractured horizontal wells in several different western Canadian formations. By careful analysis and accounting for the volumes of CO2 injected and returned during flowback, it will be shown that significant volumes of CO2 remain sequestered in the formation; in some cases up to 75% of the injected volume. With more stringent carbon regulations coming into effect in Alberta in 2017 (and Canada in 2020), this opens up a potential new avenue for emitters to utilize and store some of the CO2 they emit - into formations they are actively developing, while at the same time potentially monetizing carbon credits.
This is believed to be the first definitive study proving that CO2 is sequestered during hydraulic fracturing operations in organic rich shales and tight sandstone reservoirs. The study will show that there is a net environmental benefit to hydraulic fracturing with anthropogenic CO2 from an overall perspective. It will be shown that this unique application of CCUS also has significant economic benefit to the producer.
