Can the Viscoelasticity of HPAM Polymer Solution Make the Polymer Flooding Compete with Gel Treatment to Improve Sweep Efficiency? A Comparison with Different Polymer Gel Systems
Authors: Khamees Tariq K , Flori Ralph E 
Published: March 2019

Abstract
Improving sweep efficiency from heterogenous reservoirs necessitates the injection of gel treatment and/or polymer solution to lower the degree of heterogeneity and to lower the mobility ratio, respectively. In this study, three gel systems were compared with partially hydrolyzed polyacrylamide (HPAM) solution. The purpose of this study was to show the ability of the viscoelastic properties of the HPAM to enhance the sweep efficiency compared to the selected gel systems. The model was one quarter of five- spot pattern with one injector and one producer. The injection rate was 525 bbl/day. The selected simulator to run the scenarios was UTGEL, while the selected gel systems were colloidal dispersion gel (CDG), polymer/chromium chloride gel, and polymer/chromium malonate gel. Two polymer concentrations (0.1 and 0.15 wt. %) were used and three salinities were considered (5000, 10,000, and 20,000 mg/l).
This study showed interesting results regarding the ability of the viscoelastic properties of the HPAM polymer solution to yield recovery factors close or similar to those recovery factors obtained from the selected polymer gel systems. The results also revealed that lowering the salinity of post-treatment water could boost the performance of the polymer solution and make the polymer flooding more effective than gel systems. The results also showed that regardless the duration of injecting the polymer gel system, the HPAM polymer solution still yielded promising results, particularly if low-salinity water was implemented after the treatment.

Abstract
Microbial-induced problems in oil and gas incur high costs and cause severe environmental and safety concerns. Most of these problems are directly caused by surface-adhered bacteria colonies known as biofilms. Distinct populations of bacteria within a biofilm can symbiotically alter surrounding conditions that favor proliferation to the extent that leads to corrosion, plugging, and H2S souring. Biocides are antimicrobial products used to eliminate and prevent bacterial growth. The purpose of this initial study is to measure performance of biocides against anaerobic planktonic and sessile bacteria. The three anaerobic conditions tested were biocide performance against planktonic bacteria, against established biofilm, and inhibition of biofilm growth.
Biocides containing two types of quaternary ammonium compounds and blends with glutaraldehyde were evaluated against sulfate reducing bacteria (SRB) and acid producing bacteria (APB) in both planktonkic and sessile forms. As expected, all of the biocides tested were effective against planktonic bacteria. Quaternary type biocides were found to be particularly effective at controlling sessile anaerobes. Surprisingly, the addition of glutaraldehyde did not appear to provide synergistic benefits and actually had a negative dilutory effect on the performance against biofilms. In all cases, dialkyl dimethyl ammonium chloride (DDAC) was the most efficient biocide in controlling all bacterial forms tested, both planktonic and sessile.
Differentiation and Quantification of Corrosive Amines Through Simple Chemical Process

Published: March 2019

Abstract
A new method has been developed to differentiate and quantify the amount of primary amines through a simple chemical process. Colored cyclic adduct compounds are formed by reaction of selective chemicals with primary amine. This adduct formation is preferential to the primary amine, even in the presence of a mixture of secondary and tertiary amines. The adduct shows selective enhanced fluorescence emission at 475-nm wavelength under specific excitation with 420 nm. Due to enhanced fluorescence activity, quantification becomes possible, even below a 1-ppm concentration of specific primary amine. A chemical matrix, formulated with the mixture of different concentrations of primary, secondary and tertiary amines, helps to differentiate and quantify primary amines present in the mixture, even at lower concentrations. This method is validated under synthetic field brine conditions to detect and quantify primary amines towards field applications.
First Occurrence of a Shale Oil with Trimodal Carbon Chain Distribution and Paraffins Higher than Nonacontane C90H182: A Real Fail Test for Existing Chemistries and Methods

Abstract
A major shale producer in North America with established oil and gas production was facing challenges with severe paraffin deposition in downhole tubing and flowlines. Since chemical recommendations based on traditional screenings failed to deliver adequate inhibition, the operator turned to a costly remediation program to maintain production. We aimed to revisit the case, do a root cause analysis, and look for a potential chemical solution for cost savings. The field deposit obtained from the producer proved to be quite complex and introduced limitations with our current internal HTGC method for carbon chain analysis. Upon analysis, components present in the sample were found to exceed the solidity limits of the carrier system, carbon disulfide (CS2) and would precipitate out of the solution and form a two-phased system. These components were believed to be higher molecular weight carbon chains (HMWC) above C70+ at a high enough concentration to exceed the solvents solubility limit. This was the first time encountering such a sample in our experience. A systematic approach was applied to isolate the insoluble HMWC and further outsourced analysis. A MALDI-TOF and High-Resolution Carbon-13 NMR was utilized to confirm the presence of C90+ chains within the deposit at a high enough concentration to have a trimodal paraffin distribution system. To our knowledge, this is the first time a trimodal system has been documented.

Abstract
Background

We report the case and management of a patient that started with primary cornea guttata symptoms after cataract surgery with trifocal intraocular lens (IOL) implant. The unusual postoperative presentation of the disease in association with a trifocal IOL resulted in increased corneal surface aberrations that resulted in visual dissatisfaction.

Case presentation

A 67 year-old male was evaluated due to blurred vision for two months, as well as a desire to stop using glasses in his everyday life. At the initial refraction, myopia, corneal astigmatism and nuclear cataract were diagnosed in both eyes. A nuclear cataract was diagnosed in both eyes. Phacoemulsification surgery was performed in OS, implanting a trifocal IOL. The postoperative refraction in OS was -1.25DCx120º, with a best-corrected visual acuity (BCVA) of 20/20. Six months later, the patient kept complaining of blurred vision and night glare. In slit lamp examination, corneal guttae were denoted and changes in corneal endothelium morphology suggested primary cornea guttata. A monofocal IOL exchange was performed in order to reduce corneal aberrations with excellent outcome at 2-year follow up.

Conclusions

Screening for endothelial dysfunction is a key element for successful outcomes in cataract surgery. Corneal guttae accent optical aberrations when in combination with premium IOLs.

Integrating ICT in teacher training has become an absolute necessity over recent years. This research highlights the role of training as a means to improve Islamic religious education teacher competence in ICT. Specifically, the case-study research aim is to describe the level of ICT integration into the Islamic religious education training, referring to ‘education-and-training’, at a religious training center (RTC) in Palembang, Indonesia. Thirty teachers of Indonesian Islamic school (madrasah) and two facilitators at the RTC acted as informants in the research. Using the interactive model of qualitative analysis by Miles and Huberman, the research results indicated that the participants have already integrated ICT but were restricted to using presentations, especially the PowerPoint computer program. Secondly, age and technical problems became the major constraints to realize such integration. With respect to the availability of facilities, the RTC is in good category.

Authors: Ahmad Muhsin Ibrahim 
Published: March 2019

The management of foreign reserves is an important issue because achieving an appropriate and secure level of these reserves contributes to maintaining internal and external stability by ensuring stability in the general level of prices and maintaining the value of the local currency to prevent the flight of capital abroad. In addition to its role in the face of shocks and external crises. That is, the size of the safe reserves is considered the safety valve for the economy towards the internal and external crises that the economy can face.
The research proved the effectiveness of the Central Bank of Iraq in the management of foreign reserves for the period (2005-2017) by achieving two objectives at the same time, which is to maintain adequate and appropriate size of these reserves in accordance with international standards and indicators adopted on the one hand, in addition to maintaining the stability of the general level of prices and reducing inflation rates , Through the stability of the local currency exchange rate, which is one of the indicators of economic stability, on the other.
Effects of a Smartphone-Based Approach-Avoidance Intervention on Chocolate Craving and Consumption: Randomized Controlled Trial
Authors: Meule Adrian , Richard Anna , Dinic Radomir , Blechert Jens 
Published: March 2019

Background
Repeatedly pushing high-calorie food stimuli away based on joystick movements has been found to reduce approach biases toward these stimuli. Some studies also found that such avoidance training reduced consumption of high-calorie foods.

Objective
This study aimed to test effects of a smartphone-based approach-avoidance intervention on chocolate craving and consumption, to make such interventions suitable for daily use.

Methods
Within a 10-day period, regular chocolate eaters (n=105, 86% female) performed five sessions during which they continuously avoided (ie, swiped upward) chocolate stimuli (experimental group, n=35), performed five sessions during which they approached and avoided chocolate stimuli equally often (placebo control group, n=35), or did not perform any training sessions (inactive control group, n=35). Training effects were measured during laboratory sessions before and after the intervention period and further continuously through daily ecological momentary assessment.

Results
Self-reported chocolate craving and consumption as well as body fat mass significantly decreased from pre- to postmeasurement across all groups. Ecological momentary assessment reports evidenced no differences in chocolate craving and consumption between intervention days and rest days as a function of the group.

Conclusions
A smartphone-based approach-avoidance training did not affect eating-related and anthropometric measures over and above measurement-based changes in this study. Future controlled studies need to examine whether other techniques of modifying food approach tendencies show an add-on benefit over conventional, monitoring-based intervention effects.

Published: March 2019

Background
One reason for the introduction of digital technologies into health care has been to try to improve safety and patient outcomes by providing real-time access to patient data and enhancing communication among health care professionals. However, the adoption of such technologies into clinical pathways has been less examined, and the impacts on users and the broader health system are poorly understood. We sought to address this by studying the impacts of introducing a digitally enabled care pathway for patients with acute kidney injury (AKI) at a tertiary referral hospital in the United Kingdom. A dedicated clinical response team—comprising existing nephrology and patient-at-risk and resuscitation teams—received AKI alerts in real time via Streams, a mobile app. Here, we present a qualitative evaluation of the experiences of users and other health care professionals whose work was affected by the implementation of the care pathway.

Objective
The aim of this study was to qualitatively evaluate the impact of mobile results viewing and automated alerting as part of a digitally enabled care pathway on the working practices of users and their interprofessional relationships.

Methods
A total of 19 semistructured interviews were conducted with members of the AKI response team and clinicians with whom they interacted across the hospital. Interviews were analyzed using inductive and deductive thematic analysis.

Results
The digitally enabled care pathway improved access to patient information and expedited early specialist care. Opportunities were identified for more constructive planning of end-of-life care due to the earlier detection and alerting of deterioration. However, the shift toward early detection also highlighted resource constraints and some clinical uncertainty about the value of intervening at this stage. The real-time availability of information altered communication flows within and between clinical teams and across professional groups.

Conclusions
Digital technologies allow early detection of adverse events and of patients at risk of deterioration, with the potential to improve outcomes. They may also increase the efficiency of health care professionals’ working practices. However, when planning and implementing digital information innovations in health care, the following factors should also be considered: the provision of clinical training to effectively manage early detection, resources to cope with additional workload, support to manage perceived information overload, and the optimization of algorithms to minimize unnecessary alerts.

El aparato fotográfico: ¿instrumento, máquina o aparato?
Authors: Calderón Natalia Cristina 
Published: March 2019

El aparato fotográfico cuya emergencia se sitúa a mediados del siglo XIX no ha sido perfectamente situado al interior de la historia de la técnica, considerándosele en ocasiones como una simple herramienta o instrumento cuya utilidad se dio principalmente en el ámbito de la investigación científica, otras veces otorgándosele el estatuto de máquina, acentuando esta vez el automatismo de su funcionamiento. Ambas visiones nos parecen insuficientes puesto tanto una como otra presentan una cierta parcialidad en la comprensión del aparato, el cual no debe ser reducido a su mero carácter óptico ni a su automatismo, puesto que este es además una forma de registro, de memoria. Nuestro interés se enfocará en demostrar cómo la fotografía debe ser pensada como « aparato », es decir, como un elemento complejo al interior de la historia de la técnica; que no solamente fue capaz de perfeccionar nuestra visión considerada como deficiente, sino que al mismo tiempo fue capaz de otorgar una nueva temporalidad y un tipo de percepción específica a toda una época.
