Evaluation of LCMs in Cement to Seal Wide Natural Fractures
Authors: Lewis Sam , Tambe Romana , Dumbre Maithili , Ahuja Gopal , Sharma Abhishek 
Published: October 2017

Abstract
Lost circulation is a major contributor to nonproductive time (NPT). It occurs during drilling as well as while cementing the well. To cure the losses, lost circulation materials (LCMs) are widely used. In severe cases when the fracture size is larger than the LCMs, sealing is not effective and does not sustain high differential pressures. The focus of this study is to provide a solution to plug wide natural fractures at high differential pressures using LCM in cement.
Evaluation of LCMs was based on performance tests conducted using a permeability plugging apparatus (PPA). The individual LCMs and combinations of them were used to perform the study. High differential pressures of 2,500 psi and slot widths of 1, 3, and 5 mm were used during testing. Observations were made in terms of time to form the seal, cumulative volume of cement slurry lost before a seal was formed, and the efficiency of the seal. The cement slurry loaded with LCM was tested for rheology, suspension, and compressive strength development.
LCMs having different geometry, such as granular, lamellar, fibers, and resilient graphite, were studied either individually or in combination. For a 5-mm slot and differential pressure of 2,500 psi, it was observed that the combination of LCMs performed superiorly compared to the individual LCMs in terms of loading required, time to plug, and slurry lost before an effective seal was formed. Fibers are bridging material that form an interlocking net over the pores or fracture and prevent other particles and fluids from passing through. This physical interaction of LCMs with the cement slurry forms an effective seal that demonstrates resiliency at high differential pressures and wide fracture widths. Inclusion of these LCMs has minimal effect on other slurry properties, such as compressive strength and stability. This paper also presents observations for various potential fracture widths vs. LCM combinations based on these results.
A combination of LCMs was developed that can be used in extreme loss circulation zones to seal wide fractures at high differential pressures.
Ultra-Long Stroke and Intelligent Rod Pumping System for Producing Difficult Wells and/or Fluids

Published: October 2017

Abstract
Worldwide, as conventional oil resources are depleted, the reciprocating sucker rod pumping systems recognized as the most widely applied mean of artificial lift system for onshore wells. The popularity of this system is attributed to its durability, simplicity, and flexibility. The advanced technologies in surface and downhole equipment overcome many of the old problems, such as; producing difficult fluids (high gas and/or sand, corrosive fluids and heavy crude) and producing unconventional wells.
The necessity to maximize production and produce difficult fluids in higher economic efficiencies for rod pumped wells has created a high demand for ultra-long stroke lengths and high capacity units. The reasons behind that are the advantages of using this type of surface pumping units as compared with conventional beam units. This system allow for producing greater liquid rates with less downhole pump/rods/tubing problems. This increases the mean time between failures (MTBF) due to the reduced number of stress reversals, peak load and stresses (total amount of rod stretch caused by the load differentials between minimum and maximum polished rod loads).
This paper will present the new intelligent long stroke reciprocation pumping system for well production & cost optimization and produce difficult wells and/or fluids. This is additional to enhancing the safety by reducing the well site operations to change well running parameters for well optimization. All will perform automatically without relying on manpower interference at well-site. This achieved by the World's Longest Intelligent sucker rod unit stroke length (up to 372 inch) with highest lifting Capability up to 80,000 lbs. The system is fully Automatic/Independent Variable Speed Up or Down and control pumping speed with and integrated expert supervisory control. Also it will highlight the benefits achieved by applying the up-to-date in reciprocating pumping technology as well as the use of expert supervisory control which analyzes the wells using intelligent artificial lift system. Actual well data will be shown from successful field results.
The application of this novel technology will help to:Allow to produce high volume from deep wells.Reduce OPEX by Minimize Well InterventionsDue to the long slow stroke and soft turn-around and less friction between the rods and tubing will greatly decrease side loading. Also the fewer Cycles will Extended BHP, tubing and sucker rod lifeEqual or provide greater production at a Lower SPM

For the success of endodontic treatment, the knowledge of the internal anatomy becomes essential. Objective: to analyze the prevalence of lower incisor canals in a clinical and tomographic analysis. Material and methods: 148 lower incisors were used, measured, and evaluated through periapical radiograph and computed tomography. Results: in relation to the number of canals, 107 teeth(72.3%) presented a single canal, while 41 teeth (27.7%) presented two canals. Of the 41 teeth presenting 2 canals, 3 teeth presented independent canals (2.03%) and 38 teeth had 2 canals that joined at some point of the canal path (25.67%). Conclusion: The prevalence of two canals in the lower permanent human incisors was 27.7%; of these, 2.03% were independent. The main point of root canal union was at the apical third (20.94%). The most commonly found root canal shape was round in cervical third, flattened in middle third, and round in third apical.

Singleton Merten Syndrome is a rare disease characterized by the presence of the dental dysplasia phenotype, calcifications in the aorta, progressive wear and loss of bone protein (osteoporosis) in the hands and feet. Patients have muscle weakness, poor motor development, abnormal dentition, deformities of thefeet and hands, and skin lesions. Objective: This report describes the maxillomandibular rehabilitation of a patient with Singleton Merten Syndrome and an allergic reaction to the acrylic resin through maxillary overdenture and mandibular partial removable denture. Case report: Female patient, 18 years old, with clinical characteristics of Singleton Merten Syndrome and allergic reaction to acrylic resin, with complaints of loss of function and esthetics dueto the absence of several teeth, but with the presence of unerupted maxillary and mandibular tooth buds. Maxillary overdenture and mandibular removable partial denture were made of polyethylene. Conclusion: The rehabilitation treatment with maxillary overdenture and mandibular partial removable denture provided better facial muscle support, restoring masticatory function and facial esthetics. With this treatment, it was possible to reestablish patient’s satisfactionand self-esteem due to the correct construction of the prostheses, and minimize hypersensitivity reactions in the oral mucosa, which allowed the use of these prostheses by the patient without any complications.
ATP-binding Cassette Exporters: Structure and Mechanism with a Focus on P-glycoprotein and MRP1
Authors: Arana Maite Rocío , Altenberg Guillermo Alejandro 
Published: October 2017

Background:Proteins that belong to the ATP-binding cassette superfamily include transporters that mediate the efflux of substrates from cells. Among these exporters, P-glycoprotein and MRP1 are involved in cancer multidrug resistance, protection from endo and xenobiotics, determination of drug pharmacokinetics, and the pathophysiology of a variety of disorders.Objective:To review the information available on ATP-binding cassette exporters, with a focus on Pglycoprotein, MRP1 and related proteins. We describe tissue localization and function of these transporters in health and disease, and discuss the mechanisms of substrate transport. We also correlate recent structural information with the function of the exporters, and discuss details of their molecular mechanism with a focus on the nucleotide-binding domains.Methods:Evaluation of selected publications on the structure and function of ATP-binding cassette proteins.Conclusions:Conformational changes on the nucleotide-binding domains side of the exporters switch the accessibility of the substrate-binding pocket between the inside and outside, which is coupled to substrate efflux. However, there is no agreement on the magnitude and nature of the changes at the nucleotide- binding domains side that drive the alternate-accessibility. Comparison of the structures of Pglycoprotein and MRP1 helps explain differences in substrate selectivity and the bases for polyspecificity. P-glycoprotein substrates are hydrophobic and/or weak bases, and polyspecificity is explained by a flexible hydrophobic multi-binding site that has a few acidic patches. MRP1 substrates are mostly organic acids, and its polyspecificity is due to a single bipartite binding site that is flexible and displays positive charge.

Published: October 2017

Background:Application of attachment theory in school contexts lacks empirical evidence. The Attachment Aware Schools pilot project was commissioned by two Local Authorities in England to improve the educational outcomes of Looked After Children, and to build an evidence base. Informed by attachment research, the Attachment Aware Schools program provides a coherent and integrated theoretical framework, discourse, and practice for all practitioners working with children and young people.Objective:The primary focus was to provide whole school and targeted attachment-based strategies to support children’s well-being, behavior, and academic attainment. This paper; however, documents a secondary objective, which was to facilitate collaborative partnerships with families.Method:As part of the mixed methods approach to the Attachment Aware Schools project, a series of case studies were collected and thematically coded. The case studies were generated by practitioners using an outcomes-based framework.Results:Although the case study sample size is small (N=10), the case studies presented here illustrate how the Attachment Aware Schools program can promote increased home-school engagement and shared practice between home and school. Outcomes include improved home-school relationships, reductions in behavioral incidents, and improved family dynamics.Conclusion:Attachment Aware Schools can be a vehicle for facilitating supportive home-school collaborative partnerships with positive outcomes for vulnerable children and young people.

La región de La Montaña en el estado de Guerrero, al sur de México, presenta altos índices de pobreza y deforestación. Al mismo tiempo, sus habitantes muestran una particular dependencia de los bosques para la extracción de madera para leña. El objetivo de este trabajo fue caracterizar y cuantificar el uso de la leña y determinar su disponibilidad en las diferentes unidades del paisaje. Para identificar especies utilizadas y preferidas, fueron encuestadas 60 viviendas en tres localidades con diferentes altitudes. Se midió la cantidad de leña consumida usando los métodos Día promedio y Medición directa, basados en el peso de la leña utilizada. Para evaluar la disponibilidad de leña se caracterizó la composición y estructura florística de los fragmentos de bosques más conservados y con extracción mínima de leña, y se extrapoló para toda el área de estudio. Se encontró que el proceso de utilización de las especies es similar a lo largo del gradiente altitudinal: en 100% de las viviendas se utiliza leña diariamente con un promedio de consumo per cápita de 2.06 kg y 1.70 kg (según el método) y 63% de los usuarios realiza la extracción de árboles completos principalmente de especies del género Quercus. Se estimó una disponibilidad de biomasa viva para leña de 28 t ha-1 y 14 t ha-1en fragmentos de bosque cerrado y abierto, respectivamente. Por las similitudes encontradas en términos de uso y disponibilidad, es posible considerar, para el establecimiento de proyectos de restauración productiva, las diferentes unidades estudiadas como una unidad ambiental.

Authors: Crookston Benjamin T , West Joshua H , Hall P Cougar , Dahle Kaitana Martinez , Heaton Thomas L , Beck Robin N , Muralidharan Chandni 
Published: October 2017

Background
Mental and emotional self-help apps have emerged as potential mental illness prevention and treatment tools. The health behavior theory mechanisms by which these apps influence mental health–related behavior change have not been thoroughly examined.

Objective
The objective of this study was to examine the association between theoretical behavior change mechanisms and use of mental and emotional self-help apps and whether the use of such apps is associated with mental health behaviors.

Methods
This study utilized a cross-sectional survey of 150 users of mental or emotional health apps in the past 6 months. Survey questions included theory-based items, app engagement and likeability items, and behavior change items. Stata version 14 was used to calculate all statistics. Descriptive statistics were calculated for each of the demographic, theory, engagement, and behavior variables. Multiple regression analysis was used to identify factors associated with reported changes in theory and separately for reported changes in actual behavior after controlling for potentially confounding variables.

Results
Participants reported that app use increased their motivation, desire to set goals, confidence, control, and intentions to be mentally and emotionally healthy. Engagement (P<.001) was positively associated with the reported changes in theory items, whereas perceived behavior change was positively associated with theory (P<.001), engagement (P=.004), frequency of use of apps (P=.01), and income (P=.049).

Conclusions
Participants reported that app use increased their motivation, desire to set goals, confidence, control, and intentions to be mentally and emotionally healthy. This increase in perceptions, beliefs, and attitudes surrounding their mental and emotional health was considerably associated with perceived change in behavior. There was a positive association between the level of engagement with the app and the impact on theory items. Future efforts should consider the value of impacting key theoretical constructs when designing mental and emotional health apps. As apps are evaluated and additional theory-based apps are created, cost-effective self-help apps may become common preventative and treatment tools in the mental health field.
