Analyzing the impact of system architecture on the scalability of OLTP engines for high-contention workloads
Authors: Appuswamy Raja , Anadiotis Angelos C. , Porobic Danica , Iman Mustafa K. , Ailamaki Anastasia 
Published: December 2017

Main-memory OLTP engines are being increasingly deployed on multicore servers that provide abundant thread-level parallelism. However, recent research has shown that even the state-of-the-art OLTP engines are unable to exploit available parallelism for high contention workloads. While previous studies have shown the lack of scalability of all popular concurrency control protocols, they consider only one system architecture---a non-partitioned, shared everything one where transactions can be scheduled to run on any core and can access any data or metadata stored in shared memory.
In this paper, we perform a thorough analysis of the impact of other architectural alternatives (Data-oriented transaction execution, Partitioned Serial Execution, and Delegation) on scalability under high contention scenarios. In doing so, we present Trireme, a main-memory OLTP engine testbed that implements four system architectures and several popular concurrency control protocols in a single code base. Using Trireme, we present an extensive experimental study to understand i) the impact of each system architecture on overall scalability, ii) the interaction between system architecture and concurrency control protocols, and iii) the pros and cons of new architectures that have been proposed recently to explicitly deal with high-contention workloads.
Persistent impairment in working memory following severe hyperglycemia in newly diagnosed type 2 diabetes
Authors: Cerasuolo Joseph , Izzo Anthony 
Published: December 2017

Summary
Acute hyperglycemia has been shown to cause cognitive impairments in animal models. There is growing appreciation of the numerous effects of hyperglycemia on neuronal function as well as blood–brain barrier function. In humans, hypoglycemia is well known to cause cognitive deficits acutely, but hyperglycemia has been less well studied. We present a case of selective neurocognitive deficits in the setting of acute hyperglycemia. A 60-year-old man was admitted to the hospital for an episode of acute hyperglycemia in the setting of newly diagnosed diabetes mellitus precipitated by steroid use. He was managed with insulin therapy and discharged home, and later, presented with complaints of memory impairment. Deficits included impairment in his declarative and working memory, to the point of significant impairment in his overall functioning. The patient had no structural lesions on MRI imaging of the brain or other systemic illnesses to explain his specific deficits. We suggest that his acute hyperglycemia may have caused neurological injury, and may be responsible for our patient’s memory complaints.

Learning points:

Acute hyperglycemia has been associated with poor outcomes in several different central nervous system injuries including cerebrovascular accident and hypoxic injury.

Hyperglycemia is responsible for accumulation of reactive oxygen species in the brain, resulting in advanced glycosylated end products and a proinflammatory response that may lead to cellular injury.

Further research is needed to define the impact of both acute and chronic hyperglycemia on cognitive impairment and memory.

BACKGROUND:
Although medical marijuana (MM) may have utility in the supportive care of children with serious illness, it remains controversial. We investigated interdisciplinary provider perspectives on legal MM use in children with cancer.

METHODS:
We sent a 32-item, cross-sectional survey to 654 pediatric oncology providers in Illinois, Massachusetts, and Washington characterizing MM practices, knowledge, attitudes, and barriers. Forty-eight percent responded; 44% (n = 288) were included in analyses. Providers were stratified by status as legally eligible to certify (ETC) for MM. We used Fisher’s exact and Wilcoxon rank tests and univariate and multivariate logistic regression models for group comparisons.

RESULTS:
The provider median age was 35 years (range 22–70 years); 33% were ETC (83 physicians; 13 Washington state advance practice providers). Thirty percent of providers received ≥1 request for MM in the previous month. Notably, only 5% of all providers knew state-specific regulations. ETC providers were more likely to know that MM is against federal laws (P &lt; .0001). Whereas most providers (92%) reported willingness to help children with cancer access MM, in adjusted models, ETC providers were less likely to indicate approval of patient MM use by smoking, oral formulations, as cancer-directed therapy, or to manage symptoms (P &lt; .005 for all). Forty-six percent of all providers cited the absence of standards around formulations, potency, or dosing to be the greatest barrier to recommending MM.

CONCLUSIONS:
Most pediatric oncology providers are willing to consider MM use in children with cancer and receive frequent inquiries. However, ETC providers endorse less favorable attitudes overall. The absence of standards is an important barrier to recommending MM.
The History of a Decision: A Standard Vibration Test Method for Qualification
Authors: Rizzo Davinia , Blackburn Mark 
Published: December 2017

Abstract
As MIL-STD-810G, Environmental Engineering Considerations and Laboratory Tests, and subsequent versions have incorporated multiple-degree-of-freedom (MDOF) vibration test methodologies, it is important to understand the history and factors that drove the original decision in MIL-STD-810 to focus on single-degree-of-freedom (SDOF) vibration testing. Examining the thought process behind early MIL-STD-810 vibration test methods is useful when considering MDOF testing now that it is feasible with today's technology and documented in MIL-STD-810. This paper delves into the details of the decision made in the 1960s to develop the SDOF vibration testing standards in MIL-STD-810 beyond the limitations of technology at the time. This paper also considers the implications for effective test planning today considering the advances in test capabilities and improvements in understanding of the operational environment.
BIOÉTICA, BIODIVERSIDAD Y DESARROLLO HUMANO EN LA CIUDAD DE BOGOTÁ D.C.: Reflexión a partir de criterios bioéticos para la resolución de conflictos ambientales
Authors: Osorno Acosta Viviana 
Published: December 2017

<p>La ciudad de Bogotá D.C. se encuentra en constante expansión, lo que ha obligado a los ciudadanos a ubicarse en los diferentes terrenos disponibles, que en muchos casos suelen ser áreas consideradas protegidas dada su importancia ecológica como reservorios de biodiversidad. Es ahí, cuando aparece el conflicto entre desarrollo y la biodiversidad urbana, donde las decisiones que se tomen pueden llevar a la pérdida irreversible del equilibrio ecosistémico de estas áreas protegidas, y los beneficios que estos ofrecen a los seres humanos. De acuerdo a lo anterior, este articulo plantea una reflexión a partir criterios bioéticos para la resolución de los conflictos ambientales que surgen cuando se contempla el desarrollo humano de Bogotá, desde una perspectiva económica que no contempla la conservación de la biodiversidad. A partir de dicha reflexión, surge como posibilidad considerar el principio de precaución antes de tomar decisiones que tengan consecuencias irreversibles sobre la vida de la ciudad. </p>
Buckling Analysis of Tubular Strings With Connectors Constrained in Vertical and Inclined Wellbores
Authors: Huang Wenjun , Gao Deli , Liu Yinghua 
Published: December 2017

Summary
A new concept is proposed in the local tubular mechanical model, which provides a more-sophisticated description of tubular mechanical behaviors from a local perspective. The principles and assumptions for the local mechanical model are presented. Under these assumptions, the mechanical behaviors of tubular strings with connectors under nonbuckling/lateral-buckling, interhelical-buckling, and intrahelical-buckling modes in vertical and inclined wellbores are studied. The critical interhelical-buckling and intrahelical-buckling loads are deduced with the assumed load-displacement curve and potential-energy factor. The contact states under every buckling mode are divided into no contact, point contact, and wrap contact, and the critical contact loads are deduced with critical contact conditions. The results of critical buckling loads, critical contact loads, contact forces, and maximum bending moments are compared, and these results are given in explicit forms for the convenience of application. The results show that buckling mode transforms from nonbuckling/lateral buckling to interhelical buckling to intrahelical buckling, and contact state transforms from no contact to point contact to wrap contact with the increase of axial force. The effects of connectors on buckling behaviors are determined by both the geometric and mechanical parameters of tubular strings with connectors. Connectors can inhibit the buckling problem and increase the axial force and torque transfer, but may increase the possibility of tubular failure. Therefore, these two effects of connectors should be considered comprehensively in the optimal design of connectors on tubular strings.
Best Practices for Wellbore Cleanup and Displacements in Openhole Sand-Control Completions

Published: December 2017

Summary
At some stage after drilling to target depth and before pumping the gravel-packing treatment or before putting the well on production, the drilling fluid is typically displaced from the wellbore. Practices in the industry vary significantly depending on the primary drivers of the completion engineers, sometimes with undesirable results. Inefficient wellbore displacements can cause a variety of problems, including increased nonproductive time, reduced well productivity, and incomplete gravel packing through various mechanisms.
In this paper, we detail our best practices to ensure efficient wellbore displacements for sand-control completions on the basis of learnings from more than 500 openhole completions throughout the world from 2013 through 2016. In the design phase, these involve various compatibility tests, some of which are not commonly performed, and/or potential problems that cannot be identified easily when they are performed using conventional test procedures. Additional considerations include the modeling of fluid/fluid displacements and determining the fluid properties, pump rates, and fluid volumes required for effective displacements in a given wellbore geometry and flow paths. On the rigsite, they involve several quality-control tests, some of which have not been implemented previously.
How Do Binus University Undergraduate Students Value English in the General, Academic, and ELT Context?
Authors: Asmani Almodad B. 
Published: December 2017

Article explored the issues of the reasons and ways Indonesian undergraduate students taking English subjects at Binus University valued English, particularly in relation to its roles and influences as the dominant language and as the world’s lingua franca, and how these could give impacts on the ELT (English Language Teaching) purposes at Binus University. The study used the quantitative approach to find out the pattern of the ways they valued English in the general, academic and ELT contexts. The analysis of the quantitative results showed that there was a tendency that non-computer students value English relatively higher than computer students in terms of linguistically imperialistic ideas and macroacquisition views, while English itself tended to be respected by all students for both reasons of material/non-material benefits as well as international influences. In summary, teacher resources, teaching techniques, curriculum design, material content and assessment format should put these findings into consideration so as to make the best teaching methodology for ELT practices at Binus University.
Meeting Melbourne's future demand for water using aquifer storage and recovery
Authors: Hudson M. , Arabatzoudis C. 
Published: December 2017

Abstract
Melbourne is one of the fastest growing cities in Australia. City West Water (CWW) has developed an Integrated Water Cycle Management (IWCM) Strategy which includes the development of aquifer storage and recovery (ASR) schemes to store recycled water and storm water to assist with meeting future growth, where these schemes can be demonstrated to be viable and cost effective. The investigation and delivery of ASR projects by CWW is being undertaken in accordance with Australian guidelines, which set out a staged process for developing a scheme involving the use of recycled water. Detailed investigations into the Tertiary sand aquifer, including drilling, test pumping, injection testing, and groundwater and hydrochemical modelling, were used to inform the assessment process. These investigations have confirmed the viability of ASR at the lead site (West Werribee) following a risk-based multi-stage approach with increasing levels of assessment and financial commitment. An ASR scheme has now been constructed at West Werribee with injection trials proposed at a second site. This paper describes the staged investigation process, the key outcomes to date of CWW's investigations, the opportunities that ASR could enable, and the challenges of implementing ASR at CWW.

Authors: Nilsson F. , Ekblad M. , la Cour Jansen J. , Jönsson K. 
Published: December 2017

Abstract
Pilot-scale tests were run with ozonation for reduction of 24 pharmaceuticals at 10 full-scale wastewater treatment plants in southern Sweden. Reduction was evaluated based on doses of 3, 5 and 7 g O3/m3 at all plants. The reduction of pharmaceuticals reached on average 65% at 3 g O3/m3, 78% at 5 g O3/m3 and 88% for 7 g O3/m3 in terms of total concentration of pharmaceuticals. Specific ozone dose (ratio O3:TOC) was found to be highly influential on pharmaceutical removal. At two WWTPs, the pharmaceutical removal was severely reduced.
Demonstration of innovative MABR low-energy nutrient removal technology at Chicago MWRD
Authors: Peeters J. , Adams N. , Long Z. , Côté P. , Kunetz T. 
Published: December 2017

Abstract
An innovative MABR (membrane-aerated biofilm reactor) membrane technology was demonstrated at the O'Brien Water Reclamation Plant (OWRP) of the Metropolitan Water Reclamation District of Greater Chicago (Chicago MWRD). The demonstration unit was equipped with one full-scale membrane cassette. The technology was evaluated for its potential to improve performance for total suspended solids (TSS) and ammonia removal during stressed conditions (specifically cold temperature peak flow periods) and to meet future effluent phosphorous limits. Over a period of 9 months, the MABR oxygen transfer rate was stable and ranged between 8 and 12 g-O2/d/m2 of membrane surface area. The nitrification rate varied between 0.5 and 2.5 g-N/d/m2 and was affected primarily by the ammonia loading rate and the feed carbon to nitrogen ratio. Most of the oxygen transferred was accounted for by nitrification. The MABR hybrid process enables important process improvements while reducing plant energy consumption.
Removal of inorganics from sludge and digestate: the BiAR process
Authors: Faussone Gian Claudio , Grilc Miha , Likozar Blaz 
Published: December 2017

Abstract
This conference contribution will present a novel technology for renewable ash-free fuel production from low-value ash-containing feedstocks such as sludge digestate, wood bark or rice husks that cannot be utilized directly as a heating fuel, because of the high (low melting point) ash content. Biomass Ash Removal (BiAR) process introduces the low-temperature solvolysis in cheap solvents to transform the organic matter into a liquid state, allowing its separation from the solid ash by a simple filtration or sedimentation. After the BiAR process, all tested feedstocks reduced their ash content below threshold admitted for heating biomass set by UNI EN ISO 17225:2014 standard. As anaerobic digestion is capable to recover about 50% of the carbon in form of methane (according with COD balance), BiAR could be used to ‘retrofit’ those installation to recovery the remaining 50% organic carbon leading to a potential 100% carbon, thus energy, recovery. A potential complete compensation of costs associated to dehydration and disposal of digestate could be achieved. The PCT application has been recently filed for the BiAR process (PCT/IT2016/000140).

Published: December 2017

O Transtorno do Espectro Autista (TEA) é uma síndrome do neurodesenvolvimento, caracterizada por dificuldades nas áreas da socialização, comunicação e comportamento que, segundo a Organização Mundial da Saúde (OMS, 2017), 1 a cada 160 pessoas a possuem. O diagnóstico de autismo pode causar grandes impactos na família e, principalmente, nos pais, uma vez que o desconhecido traz consigo vários sentimentos e questionamentos. Ademais, pode desencadear estresse e transtornos de ansiedade e depressão. Metodologicamente, é uma pesquisa exploratória, quantitativa, transversal, caracterizada como um estudo preliminar que tem por objetivo identificar nos pais de crianças autistas o grau dos indicadores de estresse, ansiedade e depressão, manifestados por esses genitores. Utilizou-se como instrumento a Escala de Ansiedade, Depressão e Estresse (EADS-21) em uma amostra pequena, composta por 7 pais atendidos no Laboratório de Avaliação, Pesquisa e Intervenção em Transtorno do Espectro Autista da Universidade CEUMA. Os resultados foram analisados de forma quantitativa pelo programa estatístico SPSS (Statistical Package for Social Sciense), versão 22.0, os quais revelam que dos 7 participantes, 1 mãe apresentou sintomas de estresse leve e ansiedade moderada e 1 pai apresentou ansiedade moderada. O estudo contribuiu para a obtenção de conhecimento acerca dos agravantes que o diagnóstico de autismo pode trazer para os genitores, bem como as consequências para a sua qualidade de vida.
