<p>El enfoque de libertades fundamentales, en el marco de los derechos humanos, conlleva a que se instaure<br />como eje prioritario la igualdad en los espacios de participación, formación y convivencia. Hace referencia<br />a la importancia de reconocer las particularidades del ser humano desde las condiciones de cultura, raza,<br />género y sexo, para lograr la plenitud de su desarrollo. El examinar las políticas públicas subyacentes a la<br />inclusión educativa de las poblaciones con discapacidad en Colombia se constituye en el objetivo de este<br />trabajo de reflexión.<br />Se ha utilizado el enfoque de derechos y el enfoque inclusivo para analizar los principios de equidad, igualdad<br />y cotejo de oportunidades pues estos propenden por la participación, inclusión y desarrollo integral de </p><p>la población. Es así que la equidad y la igualdad invitan a democratizar las políticas como un proyecto de<br />identidad compartida, las políticas deben tener una responsabilidad moral individual y colectiva donde la<br />base esencial sea el reconocimiento y el respeto de la otredad. Ambos principios expresan universalidad,<br />esto significa tener en cuenta todos los intereses y las necesidades de las poblaciones marginadas.</p>
Redescription of Dawndraco kanzai Kellner, 2010 and reassignment of the type specimen to Pteranodon sternbergi Harksen, 1966
Authors: Martin-Silverstone Elizabeth 
Published: April 2017

The previous most comprehensive study on Pteranodon recognized two species of Pteranodon: P. longiceps and P. sternbergi. Complete skeletons of Pteranodon are rare, and one of the best preserved (UALVP 24238) has been identified as both P. sternbergi, and as a new genus and species, Dawndraco kanzai. Here, the specimen is redescribed, the rostral apex is identified for the first time, new details of its provenance and preparation history are presented, and its taxonomic placement is discussed. Whereas the shape of the rostrum appears at first glance to distinguish it from known Pteranodon, this feature is more parsimoniously interpreted in the context of sexual dimorphism; males have a longer and therefore more shallowly tapering rostrum. Metrics from this specimen, and from published photographs and illustrations, support the conclusion that the rostrum of UALVP 24238 is neither unique, nor grounds for recognition of a taxon distinct from Pteranodon sternbergi. Other putatively unique features of UALVP 24238 are examined and found unconvincing.

Introduction. Acute postoperative pain continues to be a dilemma to patients and clinicians.Aim. To define the efficacy, tolerability and pharmacokinetics of paracetamol and ketoprofen in patients after the abdominal aortic surgery. Setting and design in University hospital – intensive therapy unit (clinical part), clinical pharmacy and biopharmacy unit (biochemical part), and pharmaceutical company (statistical part). Prospective randomized study.Material and Methods. 40 adult patients (50–84 years) undergoing abdominal aortic surgery were randomized equally into two groups. After extubation the patients in group 1 (G1) were administered a 1 g paracetamol infusion, and in group 2 (G2) – a 100 mg ketoprofen infusion, both within 15 minutes. All the patients received an epidural infusion of bupivacaine with fentanyl. The following parameters were recorded: mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), plasma concentration of paracetamol and ketoprofen. Postoperative pain was assessed with the visual analogue scale (VAS).Results. The mean values of the MAP, HR and CVP were within normal limits in the both groups. No significant differences were noticed in the assessment of postoperative pain and total use of an opioid. The mean therapeutic plasma concentration of paracetamol and ketoprofen remained up to 180 minutes and up to 120 minutes, respecively.Conclusions. The study enabled us to conclude that intravenous paracetamol as well as ketoprofen have good effectiveness and tolerability. There is no need to modify dosage of these drugs to elderly patients. After paracetamol infusion the therapeutic plasma concentration remains longer than after the ketoprofen infusion.

Aim. The aim of the study was to assess oral health in school‑age children on the basis of subjective and objective judgement, based on selected indicators.Material and Methods. The study included students aged 10–13 years of primary and junior‑high schools in the Mid Eastern region of Wielkopolska. Oral hygiene assessment was based on a prepared subjective questionnaireas well as on the basis of indicators: API P1.I, GI, including the sex of children.Results. Of the 161 children of school age, most of them, as many as 145 showed attention to oral health, brushing teeth twice a day; some of them apply additional measures for oral hygiene – 39 children. In both sexes there were no deviations indicators examined. Between gender showed no difference, as confirmed statistically.Conclusions. Oral hygiene in children with high health awareness rated positively, it should be emphasized that despite noninvasiveness the research group of respondents accounted for a small percentage of the children invited to the study, which points the need to undertake educational activities on a larger scale.
Intracrinology and gastric cancer
Authors: Frycz Bartosz Adam , Jagodziński Paweł Piotr 
Published: April 2017

Overall incidence of gastric cancer (GC) in most populations is approximately two times higher in men than women. Therefore, steroid hormones are suspect to play a role in gastric carcinogenesis. Large amounts of steroid hormones in postmenopausal women and older men are synthesized in peripheral tissues through enzymatic conversion of blood derived precursors into active estrogens and androgens in so called, intracrine mechanism. Moreover, abnormal expression of genes encoding steroidogenic enzymes was shown in numerous malignant tumors including GC. These abnormalities can be associated with deregulated production of steroid hormones in gastric tissue and thus affect the risk of GC. For that reason this short review aims to summarize the current knowledge about the expression of genes involved in metabolism of steroid hormones in normal and malignant gastric mucosa and thus, estimate the potential of these tissues to intracrine synthesis of steroid hormones. This findings could be useful in understanding the role of above mechanism in GC and could help to find therapeutic approaches in future.

Published: April 2017

Summary
Primary and secondary oil recovery from naturally fractured oil-wet carbonate reservoirs is very low. Enhanced oil recovery (EOR) from these reservoirs by use of surfactants to alter the wettability and reduce the interfacial tension (IFT) has been extensively studied for many years, but there are still many questions regarding the process mechanisms, surfactant selection and testing, experimental design, and, most importantly, how to scale up the laboratory results to the field. Therefore, the primary objective of this study was to determine the effect of scale on the oil recovery from cores with different dimensions under low-IFT conditions. There was a particular need to perform experiments by use of cores with larger horizontal dimensions because nearly all previous experiments have been performed in cores with a small diameter, typically 3.8 cm. We adapted and modified the experimental method used for traditional static-imbibition experiments by flushing out fluids surrounding the cores periodically to better estimate the oil recovery, including the produced emulsion. We used microemulsion-phase-behavior tests to develop surfactant formulations used in this study. These surfactants gave ultralow IFT at optimum salinity and good aqueous stability. Although we used ultralow-IFT (approximately 0.002 dynes/cm) formulations for most of the experiments, we also performed tests at low IFT (approximately 0.3 dynes/cm) for comparison. A second major objective of this study was to develop a simple analytical model to predict the oil recovery as a function of vertical- and horizontal-fracture spacing, rock properties, and fluid properties. The model and experimental data were found to be in good agreement considering the many simplifications made to derive the model. The scaling implied by the model is significantly different from the traditional scaling groups in the literature. The model is useful for both interpreting the experiments and for scaling the results from the laboratory to the field.
Fiber Technology Improves Cement Bonding and Eliminates Sustained Casing Pressure
Authors: Eulberg J. , Hudson M. 
Published: April 2017

Abstract
One of the primary challenges of cementing and achieving effective zonal isolation is removing nonaqueous drilling fluid from the wellbore. Microdebonding of the cement sheath is a significant risk to overall well integrity, potentially leading to sustained casing pressure and health, safety, and environment (HSE) hazards. Field applications of a new fiber technology, designed with an optimized surfactant and mutual solvent package, have provided improved cement evaluation logs. Such trials also reduced or eliminated sustained casing pressure.
This novel application of fiber technology in weighted spacers ahead of cement placement has been tested and evaluated with success. Modified rheometer rotors were among several new techniques developed to identify the efficacy of these cement spacer packages. These tests provide greater insight into fiber, surfactant, and mutual solvent performance, and have been validated in the field with ultrasonic and acoustic cement evaluation log results.
Detailed laboratory analysis suggests superior effectiveness of the fiber, surfactant, and mutual solvent design. These preliminary results established the confidence to pursue a field trial on a number of development wells in an unconventional liquids play.
Cement evaluation logs confirmed that the new technique successfully reduced microdebonding. Additionally, sustained casing pressure was significantly reduced, indicating that the log response correlates to a tangible improvement in well integrity.
The novel use of fiber technology considerably improves the surface cleaning effectiveness of cement spacer package. Additionally, new laboratory testing procedures enhance our understanding of surfactant package function. Successful laboratory results were validated by field applications that reduced the microannulus in sample wells and minimized sustained casing pressure.
Assessing Cybersecurity Risk for Oil & Gas Mergers and Acquisitions
Authors: Hosseini Kayvon , Paul Donald L. 
Published: April 2017

Abstract
This paper presents a cybersecurity risk assessment guide for mergers and acquisitions (M&A) in the oil and gas industry. The mechanisms used for assessing cyber risk are technology neutral and developed around an organization's security culture, information systems, and operating infrastructure as they apply to the M&A process. Assessing a security infrastructure includes any connections between information technology and operational technology systems. Security considerations relating to the integration of acquired operating and information system assets are also factored into the approach. For mergers, we present six open-ended questions that are linked to specific cybersecurity functions and corresponding domains. Each domain includes industry best practices for acquirers to understand the relative maturity of a target company's cybersecurity program. Asset acquisitions require a less-comprehensive approach that focuses on four relevant areas of risk. The assessment presented in this paper can be used by companies operating across the oil and gas supply chain.
Surface Treatment for Sand Reduces Airborne Dust

Published: April 2017

Abstract
As of June 23, 2016 the Occupational Safety and Health Administration (OSHA) final rule on Occupational Exposure to Respirable Crystalline Silica took effect. This final rule establishes a new worker permissible exposure limit to airborne silica dust of 0.05 mg/m3 as an 8-hour time-weighted average. It also includes other provisions to protect employees, such as requirements for exposure assessment, hazard communication, engineering controls, respiratory protection, medical surveillance, and recordkeeping. The hydraulic fracturing industry must meet the new requirements by June 23, 2021 which gives an excellent opportunity for employers to develop and implement emerging technologies for crystalline silica control.
Herein, we report a newly developed cost-effective strategy for dust control, in which a chemical is easily sprayed onto fracturing sand. This coating will not only reduce the occurrence of airborne dust during fracturing operations, but will also improve other properties including the compressive strength of the sand and improve the proppant pack conductivity.
From sand mining, through processing up to the final delivery at the frac blender augers, numerous points of silica exposure have been identified. Several attempts have been made to implement engineering controls to limit silica exposure at the fracturing site, e.g. dust collection devices at fracturing sand units, where sand is pneumatically loaded from bulk trucks. However, it is reported that workplace concentration of airborne respirable silica exceeds the permissible exposure limit by 20 times or more.
This chemically inert technology can be applied by simply spraying the coating onto fracturing sand at concentrations as low as 0.05% by weight of proppant, with a reduction of 90% v/v of airborne dust observed through sand blast testing. Additionally crush resistance tests performed at multiple stresses have consistently shown that ~20 to 30% w/w less fines are generated when compared to untreated sand.
A field trial of this sand coating technology will show significant reduction in airborne crystalline silica at multiple test locations on a fracturing site during normal operations. It will be shown that the treated sand is free to flow and easy to operate without the use of special equipment.
This new technology in combination with already implemented PPE best practices and engineering controls for dust mitigation, such as dust/vacuum collection devices, etc., will help to enable full compliance with the new set of safety requirements established by OSHA.
High-Temperature Imbibition for Enhanced Recovery from Diatomite
Authors: Kim Tae Wook , Kovscek Anthony 
Published: April 2017

Abstract
It is difficult to produce oil from diatomite due to unique rock properties such as low permeability, high porosity, fine laminations, and fractures. Steam injection is a promising enhanced oil recovery method for diatomite, but the generation and injection of steam may lead to large energy cost and, potentially, well failures. Injection of hot water instead of steam provides a means to decouple pressure and temperature while still achieving the benefits of thermal recovery. This study investigates and compares oil recoveries from fractured diatomite cores (1.5 ″, 3.5 ″, and 5 ″diameter) using hot water and steam. Both hot water and steam injection at 200 °C were applied under spontaneous and forced imbibition conditions. Cores from two different reservoirs (A and B) were used. The B reservoir oil and brine formation were adopted for all cases. Synthetic steam boiler feed was used to create hot water and steam. An X-ray CT scanner was used to visualize in-situ phases saturations and characterize the porosity/oil saturation distribution. Wettability alteration toward water-wet conditions was observed clearly at elevated temperature (200 °C) for all cores. The Amott index, Iw, for hot water and steam injection around 200 °C with reservoir A conditions were 0.41 (A#1) and 0.36 (A#2), respectively. The final oil recovery from A cores at 45 °C and 200 °C were 62- 64 % and 78- 82 % OOIP, respectively. The A reservoir whole core with 5 ″ diameter at 45 °C showed greater oil recovery from spontaneous imbibition than the 1.5 ″ diameter core. The Iw and final oil recovery from core A with both steam and hot water injection at 200 °C was nearly identical. With B core, the Iw increased from 0.28 (45 °C, water) to 0.34 (200 °C, steam). The Iw of B core was equal to 0.33 after both hot water injection and steam injection. The final oil recoveries of both hot water and steam at 200 °C showed 76 % and 80 % OOIP, respectively. Both in situ visualization and effluent analysis shows that rock dissolution and fines migrations contribute the evolution of fracture and pore networks within the core. Therefore, results suggest that hot water provides the benefits of thermal recovery, in some regards, while decoupling pressure and temperature.
