Abstract
The objective of this work is to further explore the potential application of Machine Learning algorithms in production prediction and ultimate recovery. Intelligent Machine Learning Approaches such as Gradient Boosted Trees (GBT), Adaboost, and Support Vector Regressor (SVR) are applied to detect the most important features contributing to cumulative production prediction within the first 12 producing months. The models are applied on a data set composed of 5 wells in the Volve field in the North Sea. The collected data was then filtered and used to structure and train the different Regression algorithms and fine tune the appropriate hyperparameters. The different models were All models were evaluated by measuring the Mean Absolute Error (MAE). The generalization and precision performance of the proposed models are established by comparing the forecasted outcome after cross validation with field data. The optimized model can predict production response with high accuracy. The data-fitting process comprises of splitting the data into training using 70% of the data set, 15% validation, and 15% testing. Constructing a regression model on the training set and validating it with the test set. Recurrent application of a "cross-validation" process produces important information concerning the robustness of any regression-modeling method. Six parameters were considered as input factors to build the model. Factors affecting production prediction included on stream hours, average choke size, bore oil volume, bore gas volume, bore water volume, average wellhead pressure were used as input. The outcome showed that the developed model provided better prediction compared to analytical models with a 11.71% MAE prediction for SVR. This novel data mining application could be trained on any dataset to help predict future production performance at any conditions in any given scenario.

Authors: Sachde Darshan , McKaskle Ray , Lundeen Joe 
Published: April 2019

Offshore storage capacity has been identified as an essential part of long-term Carbon Capture, Utilization, and Storage (CCUS) strategies. Transporting the CO2 from the source onshore to the offshore storage site will be a critical aspect of the technical and economic viability of offshore storage projects. Transport of CO2 will include all processes and equipment from the preparation of CO2 for transport at the source to the wellhead at the offshore storage site. This paper will review the technology required at each step, identify risks/key knowledge gaps specific to the offshore transport process, suggest steps to be taken to advance the technology, and provide an overview of cost/economics for each step in the process.
The authors use existing literature, an analysis of analog industries (e.g., offshore natural gas transport), knowledge from CO2 onshore transport, and a technical review of the processes and equipment required for offshore CO2 transportation. This analysis is based on a hypothetical CO2 source and transport process, but will highlight some project and site-specific challenges and decisions for each step.
Specific results from the review of offshore transport process include the following:
Impact of CO2 source on transport processes, including purification and preparation for transport (e.g., dehydration/compression processes);
Comparison of offshore pipeline specifications and costs to comparable onshore applications;
Review of scenarios where alternate transportation methods (e.g., ship transport) may be considered;
Technical review of wellhead and injection facility in the offshore CO2 application in comparison to onshore analogs;
Review of the impact of CO2 utilization (e.g., enhanced oil recovery) of CO2 on transport processes;
Tabulation of gaps in data or knowledge to guide further research or industry input.
The limited experience with offshore CO2 transport projects leaves significant gaps in available data and information on these projects. By aggregating the available information on offshore CO2 transport projects, supplementing with knowledge and data from related processes (offshore natural gas transport, onshore CO2 transport), and performing a technical review of the offshore transport processes and infrastructure, some specific data needs and risks for offshore CO2 transport projects are identified.

Published: April 2019

A cibercultura, cenário contemporâneo, mediado por tecnologias digitais em rede, vem impactando, significativamente, processos educativos e alterando dinâmicas sociocomunicacionais e culturais. No contexto da mídia-educação, como produtor de estranhamento de si e do mundo, o cinema estimula o surgimento de reflexões e formas de expressão diversas. Constitui, ainda, um potente dispositivo didático-pedagógico; sobretudo quando utilizado para além da perspectiva instrucional/informacional na composição dos currículos escolares voltados ao ensino superior. Alinhados à abordagem da pesquisa nos cotidianos escolares, na multirreferencialidade e nos princípios da pesquisa-formação na cibercultura, utilizamos o filme “Um Conto Chinês”, para criar atos de currículo na perspectiva de uma ecologia de saberes, uma pedagogia das emergências e uma artesania das práticas . Desse modo, possibilitamos aos estudantes o desenvolvimento de novas visões de mundo, que contemplam, entre outras questões, a diversidade cultural e a alteridade, entrelaçando arte e educação, no contexto da pesquisa desenvolvida no Curso de Graduação em Educação da Universidade do Estado do Rio de Janeiro – UERJ, realizada no âmbito da disciplina Cotidianos e Currrículos, durante estágio de doutoramento.

Identification of optimal endogenous reference RNAs for RT-qPCR normalization in hindgut of rat models with anorectal malformations
Authors: Long Caiyun , Xiao Yunxia , Li Siying , Tang Xiaobing , Yuan Zhengwei , Bai Yuzuo 
Published: April 2019

Background
Quantitative real-time polymerase chain reaction (RT-qPCR) is a sensitive method for quantifying mRNA abundance. With relative expression analysis, however, reliable data output is dependent on stably expressed reference genes across the samples being studied. In anorectal malformations (ARMs), there is limited data on the selection of appropriate reference genes.

Purpose
This study was aimed to investigate the optimal reference genes for PCR in ARM rat models.

Methods
We selected 15 commonly used reference genes (Rps18, Actb, B2m, Gapdh, Ppia, Hprt1, Pgk1, Ywhaz, Tbp, Ubc, Rps16, Rpl13a, Rplp1, Sdha, and Hmbs) as candidate reference genes and detected their mRNA expression in ARM samples by RT-qPCR. The expression stability and variability of these transcripts were subsequently evaluated using four methods (geNorm, NormFinder, comparative ΔCt, and BestKeeper).

Results
The abundance of the candidate reference genes was qualified by RT-qPCR and the cycle threshold (Ct) values ranged between 14.07 (Rplp1) and 21.89 (Sdha). In the overall candidate genes, different variations existed across the different algorithms. A comprehensive analysis revealed that Rpl13a ranked first among the relatively stable genes, followed by Ywhaz, Rps18, Sdha, and Hmbs.

Conclusions
The most stable reference genes for RT-qPCR were Rpl13a, Ywhaz, and Rps18 in ETU-induced ARMs in rat fetus. This study provided a foundation for reference gene selection for future gene expression analyses.

Authors: Qureshi Naseem Akhtar , Sharma Sheelaj , Guru Rahul , Kahlenberg Andrea , Alharbi Mohammed Khulaif 
Published: April 2019

Background: Primary Raynaud’s disease preferentially afflicts women with 5% prevalence rate reported in general population, manifests triphasic color phenomenon along with paresthesia involving distal digits and toes and triggered by severe cold and stress.
Objective: This review critically describes several perspectives of Raynaud’s diseases with a focus on medical acupuncture.
Methods: Electronic searches of relevant data prior to 2019 published in PubMed, MEDLINE, Google Scholar, and ScienceDirect databases were made using the Boolean operators and keywords. Finally, 32 articles that addressed specifically Raynaud’s disease and acupuncture were retained for this minireview.
Results: Raynaud’s disease classified into primary and secondary is poorly understood phenomenon, lacks standard care and, hence, needs patient-centered holistic approach. Evidently, medical acupuncture with safe clinical profile has been effectively used as an alternative therapy in Raynaud’s disease. Outcome results with the use of conservative approaches, modern therapies, behavioral interventions and medical acupuncture vary considerably across the board and primary RD carries better prognosis than secondary RD.
Conclusion: Both Raynaud's disease phenomena are complex conditions; need individualized treatment approach including surgical in refractory cases and further rigor studies to unravel their pathophysiology pathways and standardized interventions.

AbstractBarriers that charge carriers experience while injecting into channels play a crucial role on determining the device properties of van der Waals semiconductors (vdWS). Among various strategies to control these barriers, inserting a graphene layer underneath bulk metal may be a promising choice, which is still lacking experimental verification. Here, it is demonstrated that graphene/metal hybrid structures can form quasi‐van der Waals contacts (q‐vdWC) to ambipolar vdWS, combining the advantages of individual metal and graphene contacts together. A new analysis model is adopted to define the barriers and to extract the barrier heights in ambipolar vdWS. The devices with q‐vdWC show significantly reduced Schottky barrier heights and thermionic field emission activation energies, ability of screening the influence from substrate, and Fermi level unpinning effect. Furthermore, phototransistors with these special contacts exhibit enhanced performances. The proposed graphene/metal q‐vdWC may be an effective strategy to approach the Schottky–Mott limit for vdWS.

AbstractBackgroundThe aim of the present study was to develop a risk calculator predictive of postoperative pneumonia in patients undergoing gastroenterological surgery.MethodsWe analyzed data from 382 124 patients undergoing eight main gastroenterological surgeries between 2011 and 2013 using the National Clinical Database in Japan. A risk model was developed using multivariate logistic regression analysis with patient data from 2011 to 2012 (n = 247 604) and validated using data from 2013 (n = 134 520).ResultsPneumonia was observed in 11 105 patients (2.9%). After the input of significant primary disease and surgical procedures, 18 patient characteristics including gender, chronic obstructive pulmonary disease, sepsis, and need for any assistance in the activities of daily living, six laboratory parameters, and two intraoperative factors were used for risk calculation. Area under the receiver‐operating characteristic curve was 0.822 (95% confidence interval, 0.817‐0.826) in the derivation group and 0.826 (0.819‐0.832) in the validation group.ConclusionThe risk calculator accurately predicted the occurrence of pneumonia following gastroenterological surgery.

AbstractThe spectrum of clinical consequences of variants in the Platelet derived growth factor receptor beta (PDGFRB) gene is wide. Missense variants leading to variable loss of signal transduction in vitro have been reported in the idiopathic basal ganglia calcification (IBGC) syndrome Type 4. In contrast, gain‐of‐function variants have been reported in infantile myofibromatosis, Penttinen syndrome, and Kosaki overgrowth syndrome. Here, we report a patient harboring a novel postzygotic variant in PDGFRB (c.1682_1684del, p.[Arg561_Tyr562delinsHis]) and presenting severe cerebral malformations, intracerebral calcifications, and infantile myofibromatosis. This observation expands the phenotype associated with PDGFRB variants and illustrates the wide clinical spectrum linked to dysregulation of PDGFRB.

BackgroundThe effect of intra‐arterial infusion of fasudil hydrochloride in patients with post‐traumatic cerebral vasospasm remains unclear. Here we report a case of intra‐arterial infusion of fasudil hydrochloride for post‐traumatic cerebral vasospasm.Case presentationA 47‐year‐old man was transferred to our hospital with a fractured skull and traumatic subarachnoid hemorrhage. As rhinorrhea of cerebrospinal fluid had not improved, repair surgery was carried out on day 4. Aphasia appeared on day 13. Magnetic resonance imaging and angiography showed an ischemic region in the left temporal lobe and vasospasm of the left middle cerebral artery. We immediately carried out angiography and diagnosed severe vasospasm of the M1 region of the left middle cerebral artery. After placing a microcatheter into the proximal middle cerebral artery, we injected fasudil hydrochloride intra‐arterially. Vasospasm improved and aphasia resolved.ConclusionIn this case, intra‐arterial infusion of fasudil hydrochloride was effective against post‐traumatic cerebral vasospasm.

Published: April 2019

ABSTRACTElectrospinning is a well‐known technique for producing nanofibers using synthetic and natural polymers like mucilage. In this study, Plantago major Mucilage (PMM) was blended with polyvinyl alcohol (PVA) as a nontoxic adding agent, in order to produce electrospun nanofiber. Electrospinning parameters (voltage, tip‐to‐collector distance, feed rate, and PMM/PVA ratio) were optimized and solution properties were analyzed. The morphology of nanofibers was investigated using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), X‐ray diffraction (XRD), and Brunauer–Emmett–Teller (BET). Mechanical strength of nanofibers was determined, and cell viability on nanofibers was discussed by MTT assay. The results of SEM indicated that the PMM/PVA (50/50) nanofibers obtained with average diameter of 250 nm. Viscosity, electrical conductivity, and surface tension of PMM/PVA solution were 550 Cp, 575 μS/cm, and 47.044 mN/m, respectively. FTIR and XRD results verified the exiting PMM in produced nanofibers and no chemical reaction between PMM and PVA. Improvement in mechanical strength and cell viability of nanofibers by adding PMM to PVA nanofibers indicated the potential application of PMM‐based nanofibers for medical and food industries. © 2019 Wiley Periodicals, Inc.

Authors: Zeman Oliver , Schwenn Michael , Petricevic Duro 
Published: April 2019

KurzfassungDas Institut für Konstruktiven Ingenieurbau verfügt seit Mitte der 1990er‐Jahre über ein eigenes mechanisches Prüflabor. Seit 2006 ist diese Prüfstelle nach ISO/IEC 17025 für eine Reihe von Prüfnormen aus dem Bereich der Befestigungstechnik nach dem österreichischen Akkreditierungsgesetz bei der Akkreditierung Austria akkreditiert, womit regelmäßig die Überprüfung der Fachkompetenz und des Vorhandenseins eines funktionierenden Qualitätsmanagementsystems durch unabhängige Sachverständige erfolgt. Im Zuge der Überführung der Normen der Reihe ISO 170xx (für Inspektions‐, Zertifizierungs‐, Kalibrier‐ und Prüfstellen relevant) durch eine neue Normengeneration wurde als eine der letzten Normen auch die ISO 17025 „Anforderungen an Prüf‐ und Kalibrierlaboratorien“ grundlegend verändert. Die unterschiedlichen Ansätze in der Gewährleistung der Kompetenz einer Prüfstelle und die Anforderungen an die Rückführbarkeit von Prüfergebnissen werden in diesem Beitrag gezielt herausgearbeitet. Anhand der Prüfstelle am Institut für Konstruktiven Ingenieurbau wird gezeigt, wie die Transformation von der ISO/IEC 17025:2005 in die ISO/IEC 17025:2017 eine qualitativ hochwertige Prüfarbeit sicherstellt.
Die praktische Umsetzung von neuen ressourceneffizienten Bauverfahren als Katalysator für Innovation im konstruktiven Ingenieurbau
Authors: Kromoser Benjamin , Kollegger Johann 
Published: April 2019

KurzfassungDie Bauindustrie ist nach wie vor von konservativen Prozessen und Bauweisen geprägt. Neue Entwicklungen mit optimierten Arbeitsabläufen, neuen Materialien und Bauverfahren, die ökologische und ökonomische Vorteile mit sich bringen, werden nur langsam angenommen. Grund dafür sind u. a. eine zunehmend dichtere und unflexiblere Normungsstruktur, die neue Entwicklungen nur bedingt berücksichtigt, und eine zunehmend geringere Bereitschaft Verantwortung in der Gesellschaft zu übernehmen. In Österreich konnten dem internationalen Trend entgegenwirkend in den vergangenen Jahren innovative Bauverfahren in großem Maßstab erstmals praktisch angewandt werden. Durch ausgewählte Versuchsprogramme in Kombination mit numerischen Berechnungsmethoden, die durch die stetige Weiterentwicklung eine genauere Beurteilung der Tragwerke vor Baubeginn ermöglichen, kann die notwendige Vorarbeit geleistet und ein hohes Sicherheitsniveau gewährt werden. Im vorliegenden Beitrag wird anhand von zwei ausgewählten Beispielen, der Egg‐Graben‐Brücke im Großarltal im Bundesland Salzburg und der Wildbrücke AM2 in Wiederndorf im Bundesland Kärnten, der Weg von der Entwicklung bis zur erstmaligen praktischen Anwendung beschrieben.
Forschungsbauwerk zur Untersuchung von Murgängen und deren Einwirkung auf Schutzbauwerke

Published: April 2019

KurzfassungAlpine Regionen sind unterschiedlichsten Naturgefahrenprozessen ausgesetzt, wie Murgängen, Rutschungen, Steinschlag und Lawinen. Murgänge definieren sich als langsam bis schnell fließende Suspension aus Wasser, Feststoffen und Wildholz, die sich dann entwickeln, wenn in kurzer Zeit große Geschiebemengen verfügbar werden . Die Kombination von hohen Geschwindigkeiten von bis zu 20 m/s und die Eigenschaft, große Blöcke zu transportieren, gefährden Infrastruktur und menschliches Leben. Für die Dimensionierung von Schutzbauwerken gegen diese Naturgefahr benötigt man realistische Bemessungswerte der auftretenden Kräfte. Zu diesem Zweck wurde im Jahr 2016 ein Forschungsbauwerk im Gadriabach in Südtirol errichtet. Das gesamte Bauwerk ist mit über 50 Sensoren ausgestattet, die die Erfassung der Einwirkungen sowie den weiteren Verlauf der Kräfte ermöglichen. Zusätzlich werden auch die für die Bemessung notwendigen Prozessparameter, wie z. B. Dichten, Fließhöhen und Geschwindigkeiten, ermittelt. In den ersten zwei Betriebsjahren wurden drei Murgänge mit Fließhöhen von 1 bis 2 m erfolgreich detektiert und gemessen. Die dabei gewonnenen Ergebnisse sollen mithelfen, die Entwicklung in der Dimensionierung von Schutzbauwerken zu verbessern.
Ultraschalluntersuchungen zur Identifikation von Schwerlastankern
Authors: Hofmann Jan , Laumann Sebastian 
Published: April 2019

KurzfassungIn nahezu allen Bereichen des Bauwesens werden Bauteile durch Befestigungsmittel miteinander verbunden oder es muss an bestehenden Bauteilen bzw. Bauwerken etwas befestigt oder nachträglich angefügt werden. Häufig sind keinerlei Aufzeichnungen oder andere Informationen über die im Tragwerk verbauten Befestigungsmittel verfügbar. Dabei spielt z. B. insbesondere die Kontrolle der vorhandenen Verankerungstiefe oder die Identifizierung des Dübels selbst eine entscheidende Rolle, ob der Dübel weiterverwendet werden kann oder ggf. ausgebaut werden muss. Im Folgenden wurde eine Auswahl von drei verschiedenen, jedoch von der Bauart ähnlichen, drehmomentkontrolliert spreizenden Dübeltypen mittels Ultraschall untersucht. Die Versuche zeigen, dass anhand der messbaren Reflexionen die Verankerungstiefe ermittelt werden kann. Des Weiteren ist es möglich, anhand eines Referenzbilds auch zwischen unterschiedlichen Dübeltypen unterscheiden zu können. Dadurch kann mittels Kerben in verschiedenen Tiefen und Abständen eine Codierung des Dübels erfolgen, sodass dieser anschließend mit Ultraschallmessungen identifiziert werden kann.
