Online Course Enrollment in Community College and Degree Completion: The Tipping Point
Authors: Shea Peter , Bidjerano Temi 
Published: May 2018

Recent research indicates that certain students are at risk of lower levels of academic performance in online settings when compared to peers who study only in the classroom. Community college students have been a population of particular concern. In this paper, we hypothesize that online course load and institutional quality may impact outcomes for such students at risk for lower levels of degree attainment. Using comprehensive data from the 30 community colleges (n=45,557) of the State University of New York (SUNY), we conducted a state-wide study to examine whether there is a “tipping point” at which online course load becomes problematic for community college learners seeking to attain a degree through a mix of online and face-to-face coursework. We also test the conjecture that some institutions may excel at supporting online learner success among more at risk populations who choose online study. Results indicate that community college students who take more than 40% of their courses online begin to lose the benefits of enhanced degree completion conferred through a mix of online and face-to-face enrollment. Moderating variables are also identified and discussed.
Drilling by the Numbers Demands Better Numbers
Authors: Rassenfoss Stephen 
Published: May 2018

Oil wells can produce large volumes of oil, gas, water, and dubious data. For example, a recent study of data from 40 wells found that the measure of the weight on the bit (WOB) was off by 18% in the average well.
The big problem was that 69% of the time this key measure of the force applied while drilling was not recalibrated when the weight of the drillstring was increased as pipe was added, which is known as WOB zeroing.
Past technical papers on data quality focused on how data were measured, not on whether drillers were regularly zeroing, said Adam Neufeldt, a research engineer at Pason.
He delivered a paper (SPE 189636) at the recent IADC/SPE Drilling Conference where multiple papers were generated about the industry’s growing use of data for analysis and control, including some questioning data quality, which could undercut the value of analytics and automation.
The demand for better-quality data is rising as operators and service companies build systems to gather and analyze real-time drilling numbers. Representatives of Anadarko, Nabors Drilling, and Occidental all presented papers at the conference describing how they are expanding their ability to gather and analyze more drilling data faster to improve drilling performance.
“We have reached the tipping point on the use of this data,” Matt Isbell, drilling optimization advisor for Hess, said during a presentation at the drilling conference about the Operators Group on Data Quality, which was formed a couple of years ago to address the problem (SPE 189626).
“The errors are significant and there are huge consequences,” said John de Wardt, president of De Wardt & Co., who is leading an industry effort to create a roadmap for drilling automation systems development. He is working with Southwest Research Institute to develop a validation system to verify sensors and systems for drilling measurement.
The Pason paper looking at WOB data shined a light on the central role played by drillers. Errors in the drilling data recorder were likely caused by drillers failing to push the button on the recorder to zero the measure.
Several experts interviewed said that if an operation was progressing smoothly, the driller would likely keep an eye on the data but not feel a need to do the update, allowing the error to grow. The study found a similar error rate in the estimates of the differential pressure that measures the force of the fluid flow driving the mud motor, which, like WOB, is used to measure the mechanical energy applied by the drill bit. Failure to regularly zero the differential pressure was a major source of error as well.
Developing an Influx-Management Envelope for a Deepwater MPD Operation
Authors: Carpenter Chris 
Published: May 2018

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 185289, “Case Study: First Experience of Developing an Influx-Management Envelope for a Deepwater MPD Operation,” by O.R. Gabaldon, P.R. Brand, M.S. Culen, I.U. Haq, R.A. Gonzalez-Luis, T. Pinheiro Da Silva, G. Puerto, and W. Bacon, Blade Energy Partners, prepared for the 2017 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference and Exhibition, Rio de Janeiro, 28–29 March. The paper has not been peer reviewed.
The influx-management-envelope (IME) concept is an advanced, innovative way to assess influx conditions in managed-pressure-drilling (MPD) operations, offering an improved tool for the decision-making process. The complete paper presents the process of developing the IME concept for a deepwater MPD operation for the first time.
The IME Concept
The IME concept defines the operational envelope in case of incidental influxes during MPD operations. It is based on kick-tolerance concepts, in which a relationship between volume and intensity of the influx is established and plotted as a graph. A resulting combination of regions within the volume-and-intensity graph depicts the conditions in which an influx can be removed safely from the wellbore by use of the elements of the primary wellbore barrier; otherwise, the secondary wellbore barrier should be engaged and the well shut in conventionally. The regions are color coded for ease of identification during the process of managing an influx. Three regions have been described:
The Green region identifies normal MPD operations, where drilling and other operations continue as planned. No influx is detected in the wellbore, and surface pressures are within planned parameters.
The Yellow region defines the operational region where an influx has been detected in the wellbore and the influx can be circulated safely to surface within the boundaries of the primary wellbore barrier.
The Red region defines the conditions in which it is deemed that some limits of the primary barrier would be exceeded during the process, indicating that the well should be secured with a secondary-barrier envelope.
The Orange Region. In this work, an additional (optional) Orange region is added as a subset of the Yellow region (Fig. 1). In the Orange region, an influx can be removed safely within the primary wellbore barrier but one or more parameters will need to be modified to avoid exceeding some limits in the process.
Technology Focus: Cementing/Zonal Isolation (May 2018)
Authors: DeBruijn Gunnar 
Published: May 2018

Technology Focus
Zonal isolation achieved with cement remains fundamental to well integrity for the full well life cycle. As I read through the abstracts and papers that have been presented in the past year, I notice several key themes: verification of cement placement, development of new materials as a barrier, development of new additives to improve the cement barrier, and enhancement of existing techniques. The fact that we are still studying and improving the cement barrier underscores how important it is as wells are pushed to new limits.
Cement-job-performance indicators are critical. From our surface observations, surface sensors, and equipment performance, we can anticipate where zonal isolation is expected. With a robust cementing process embedded in the drilling process, we can be confident in the placement of the barrier. Paper SPE 188295 includes a very complete case history.
Many efforts have been made relating to measurement of the outcome of cement jobs. New, more-powerful logging tools; better algorithms; and novel explanations are explored for each scenario that we can imagine. Paper SPE 188274 includes an excellent summary of today’s state of the art.
Our industry continues to challenge drillers to push to new limits, which requires cementing technology to reach those same limits so that annular isolation can be achieved in every well that is drilled. Extended-reach wells are reaching new lateral-reach records. Managed-pressure drilling is a technique that is spreading, which logically leads to the need for managed-pressure cementing (MPC). Paper OTC 28139 includes a case history of MPC in deep water.
Zonal isolation continues to be enhanced. The recommended additional reading provides an insight into a few of these enhancements, including abandonment practices, reverse cementing, and nanotechnology.

Abstract
Anaerobic digestion of food wastes coupled with digestate post-treatment using microalgae-based systems could recover large amounts of energy and nutrients worldwide. However, the development of full-scale implementations requires overcoming microalgae inhibition by high ammonia concentrations and low light transmittances affecting photosynthesis. This study evaluated the potential of microalgae-based reactors supplied with red light-emitting diodes (LEDs) at low intensity (660 nm and 15 µmol·m−2·s−1) to treat food waste digestate. LED reactors were compared with control reactors exposed to solar radiation. From a range of species in the inoculum, Chlorella vulgaris showed high adaptation to both lighting regimes and digestate environmental conditions, characterized by a C:N:P ratio of 74:74:1. Removal efficiencies for control and LED reactors were 84.0% and 95.8% for soluble chemical oxygen demand (COD) and 89.4% and 53.0% for ammonia, respectively. Approximately 50% of ammonia in control reactor and 15% in LED reactor was lost from the systems, whereas 17% and 36% of ammonia was transformed to organic nitrogen in control and LED reactors, respectively. Low-intensity LEDs maintained microalgae growth in levels similar to solar radiation and supported efficient digestate treatment, showing a potential for further application in optimization of full scale reactors at a relatively low energy cost.
Tracking the fate and transport of estrogens following rainfall events
Authors: Zhao Xiaomin , Lung Wu-Seng 
Published: May 2018

Abstract
Surface runoff following rainfall events can transport estrogens from agricultural land to water systems, causing potential risks to aquatic biota. This study adopted two simple models, the wash-off and empirical models, to quantify the pathway of three prevalent manure-borne estrogens, estrone (E1), 17β-estradiol (E2β) and 17α-estradiol (E2α), from agricultural land to the receiving water following rainfall events. The complex interconversion of the three estrogens during attenuation was considered in the models. These two models were calibrated and validated using the data obtained from three artificial rainfall events from the literature. The data from the first two rainfall events were used to quantify key model parameters and the data from the third rainfall event were used to validate the models. The performances of the models were then evaluated through a statistical analysis. Results show that both models can closely reproduce the mass loads of estrogens during rainfall events and that the wash-off model shows a better overall performance than the empirical model for the data used in this study.

Investigaciones sobre la paz desde América Latina: Interdisciplinariedad con perspectiva crítica
Authors: Gaussens Pierre , Ayvar Acosta María Ivette 
Published: May 2018

La paz representa un tema sumamente complejo. Su estudio es problemático, por varias razones: tanto por la relatividad intrínseca al carácter filosófico del concepto, como por las connotaciones ideológicas que lo marcan; por el carácter teleológico de una categoría que ha sido erecta desde la ONU en el ideal universal e incuestionable al que deben aspirar todas las sociedades; debido a una serie de obstáculos teóricos y metodológicos que han impedido la formulación consensuada de una definición mínima (sobre un término en sí polisémico), así como la delimitación de su universo, es decir, a una dificultad epistemológica para la construcción de un objeto de estudio compartido por una comunidad científica.<br />Todo ello, en un contexto de complejidad inherente al tema de la paz que también se explica por el amplio abanico de problemáticas que encierra la cuestión.

No obstante, este dispositivo se ha empleado fundamentalmente para describir e impugnar aquello que bajo la denominación <em>violencia de género</em> se ha concentrado en develar la violencia que los hombres ejercemos sobre las mujeres, violencia que además privilegia el espacio doméstico como aquel en donde se escenifica una amplia y diversa gama de actos y omisiones que buscan perpetuar el poder masculino.</p><p>En este texto se bosqueja el potencial de la violencia de género en tanto categoría para arrojar luz sobre otros fenómenos que, si bien son protagonizados por hombres, rara vez se leen desde una perspectiva que reconoce su trasfondo genérico. Eventos como la guerra, la delincuencia organizada o el pandillerismo por citar algunos de estos acontecimientos cuyas motivaciones tendrán, cada uno, su propia historicidad pero que se producen confabulados en la construcción social de la masculinidad.</p><p>Una vez planteada esa primera cuestión, se abre el entretelón para colocar la necesidad de revisar profunda y críticamente el modelo normativo de la masculinidad como un elemento fundamental para procurar, a distintas escalas, procesos de pacificación sostenibles.</p>

Published: May 2018

Este estudo avaliou a acessibilidade aos serviços de saúde bucal das equipes de Saúde da Família na zona urbana do município de Jauru (MT), a partir das concepções de acessibilidade organizacional e geográfica. Foi realizado uma pesquisa avaliativa da acessibilidade através de um estudo de caso, utilizando entrevistas semiestruturadas junto aos profissionais de saúde pertencentes às duas equipes de saúde bucal e usuários e não usuários destes serviços. A triangulação de dados foi conduzida pela observação direta e análise documental. A classificação da acessibilidade na Unidade de Saúde da Família I foi intermediária inferior (39%) e a Unidade de saúde da Família II apresentou uma acessibilidade incipiente (28,9%). Os aspectos estruturais foram determinantes para a definição da acessibilidade às ações odontológicas, dentre os quais se destacam: a não reposição imediata de insumos odontológicos e os equipamentos existentes em condições ruins de funcionamento. No componente do processo de acessibilidade organizacional, a ausência de acolhimento e de escuta qualificada, forma de acesso a consultas odontológicas somente por meio da equipe de saúde bucal, tempo prolongado entre a marcação da consulta e o atendimento, modelo de atendimento clínico da USF centrado no Tratamento Concluído por indivíduos foram mais frequentes. A acessibilidade encontrada nas duas ESB indica a necessidade de reorganização dos processos de trabalho dessas equipes, junto a uma polótoca específica, que formule protocolos locais em consonância com as necessidades dos usuários.Palavras-chave: Saúde da Família.

This article reveals A. Mustofa Bisriâ€™s thoughts implicitly found inhis poems. As a scholar in Nahdlatul Ulama, he has an attractive thought; he is a scholar who writes literary works. To interpret his poems needs attention to the referential meaning as a means to get into the dimension of language and reality. At symbolic level, poems are understood as a part of life expression referred to the root of knowledge. From such a method, it can be revealed some important points: first, the poems written by A. Mustofa Bisri are expressed in simple language as self-manifestation of the writer and his works. The simplicity of language needs deeper understanding to know the writerâ€™s perspective and dimension. Second, there is a similarity betweem A. Mustofa Bisriâ€™s and Sufism poems themed love and yearning to Allah.Â Tulisan ini berusaha mengungkap pemikiran penting A. MustofaBisri yang tersirat di dalam puisi-puisinya. Ia sebagai ulama di kalangan Nahdlatul Ulama memiliki pemikiran yang menarik, yakni sebagai kiai yang menulis karya sastra. Untuk memaknakan puisi-puisi yang ditulis oleh A. Mustofa Bisri, dibutuhkan perhatian pada arti referensial sebagai jalan untuk memasuki ranah bahasa dan realitas. Pada tataran simbolik, berusaha memahami puisi sebagai bagian dari ekspresi kehidupan yang dirujuk sampai pada akar pengetahuan. Dari metode seperti itu, dapat ditemukan beberapa hal penting; pertama, puisi yang ditulis oleh A. Mustofa Bisri diungkapkan dengan bahasa sederhana sebagai manifestasi diri dan ciptaanya. Kesederhanaan bahasa tersebut membutuhkan pemahaman yang lebih mendalam terkait dengan wawasan dan dimensi dari penyair. Kedua, ada kesamaan tematik puisi A.
