Tailoring Alkoxylation of Flowback Aid Surfactants for Maximum Efficiency
Authors: Carreira de Rezende Fabiola , Balloni Rabelo Rodrigo , Kinouti Lilian , Gerard Ewbank Conrado , Cueva Candido Poltronieri Olivia
Published: March 2019

In this study, a novel surfactant for flowback aid application was developed based on an optimization of well-known non-ionic surfactants. The objective was to meet intrinsic surfactant properties, such as high cloud point (CP), low surface tension (ST), adequate contact angle (CA) and low critical micelle concentration (CMC). In addition to the essential physical-chemical properties, improvement in fluid recovery and emulsion compatibility were also targeted. The surfactants were optimized by tailoring the hydrophilic head through controlled introduction of ethylene oxide and propylene oxide into different hydrophobic chains.

Surface tension measurements were made with a Dataphysics Instruments model OCA-15. Contact angles were measured using the sessile-drop method. The CMC concentration and cloud point were also conducted for physical chemical characterization. For the fluid recovery evaluation, flowback solutions were poured through 150g of 60/150 mesh- dry porous media contained in a 7 cm-inner-diameter, 9.5- cm-long column. Emulsion compatibility tests were also carried out using different proportions of crude oil and brine.

This paper evaluates various flowback additives in hydraulic fracturing applications between linear and branched alkoxylated surfactants. High cloud point enables a wide range of temperature applications and an increase in EO content showed an increase in cloud point values, contrary to PO effect. Nevertheless, CMC measurements showed that for an optimum scenario, EO addition should not be high, because undesired increases in CMC values may occur, which will affect the final surfactant dosage needed. All flowback aids demonstrated low surface tension as expected (approximately below 32 mN/m), but each being different in terms of surface wettability (contact angle), which could not be correlated with surfactant structure. Fluid recovery and kinetics of emulsion breakage increased significantly with different alkoxylation adjustments. For the new flowback aid developed, the fluid recovery was improved when compared against standard surfactants. Additionally, significant improvement was also found during emulsion breakage evaluation in terms of superior kinetics, final breakage, and water quality. This work provided a better understanding of how EO/PO affects intrinsic surfactant properties and enabled to find a surfactant that offers several benefits in terms of fluid recovery and non-emulsification of crude oil and water.

Published: March 2019

Nanofluid flooding injection technique whereby nanomaterial or nanocomposite fluids for enhanced oil recovery (EOR) have garnered attention. Although a variety of nanomaterials have been used as EOR agents, there are still some defects such as toxicity, high cost and low-efficiency displacement, which restricted the further application of these nanoparticles. Considering these problems mentioned above, it is necessary to search for another nanomaterial which is inexpensive, environmentally friendly and results in high efficiency displacement.

In this work, a natural aluminosilicate nanomaterial halloysite nanotubes (HNTs) was focused. As a new kind of nanomaterial, the effectiveness of halloysite nanotubes (HNTs) in enhancing oil recovery has not been reported yet and it is still in its infancy. The use of pristine halloysite nanotube is at risk of blocking the rock pore channel due to the intrinsic drawback of aggregation, which may be the reason. To prolong the suspension time of fluids during seeping into the small pores of low permeable reservoirs, we have proposed the HNTs/SiO2 nanocomposites. The effect of HNTs/SiO2 nanocomposites-based nanofluids on wettability alteration and oil displacement efficiency was experimentally studied. The HNTs/SiO2 nanocomposites have been prepared by sol-gel method and characterized with X-ray (XRD), Transmission Electron Microscopy (TEM) and Thermal Gravimetric Analysis (TGA). The effect of the chemical modification on the suspension stability was investigated by measuring Zeta potential and dynamic laser scattering. Results show that the HNTs/SiO2 nanofluid could significantly change the water wettability from oil-wet to water-wet condition and enhance oil production. The optimal concentration of HNTs/SiO2 was 500 ppm, which corresponded to the highest ultimate oil recovery of 39%.

Authors: Sayed Abd Elghaffar Emad , Mohamed Abotalib Ahmed , Abdel Azeem Mohamed Khalil Manal
Published: March 2019

This study aims to measure the risk disclosure level in Egyptian banks and to investigate its determinants. The sample consisted of 28 banks during the period from 2010 to 2017. An unweighted risk disclosure index including six categories was used: credit risk, market risk, liquidity risk, capital structure and adequacy risk, operational risk, and other non-financial risks. Also, a content analysis approach was used to measure the actual level of risk disclosure. The findings demonstrated that there was an average level of total risk disclosure of all sample banks. The results showed that banks with a higher percentage of independent board membership, large board size, large audit committee size, duality, higher institutional ownership, and banks audited by one of big four audit firms were more motivated to increase risk disclosure. Also, the results showed that leverage, bad news, and bank social responsibility have a negative relationship with the level of risk disclosure. Overall, the results indicated that leverage, board size, audit committee size, auditor types, independence, duality, institutional ownership, bank social responsibility, and bad news are the main factors affecting the level of risk disclosure in Egyptian banks. The findings of this paper have a number of important implications. The risk disclosure in the banking sector is important for stakeholders such as investors and depositors. Also, risk disclosure index helps the regulatory bodies to evaluate the risk disclosure practice in Egyptian banks. This paper contributes to analyzing factors affecting banks managers’ decision to disclose risk information in emerging countries such as Egypt.

Avocado is a fruit that high unsaturated fatty acid, while coconut water is fluid which has high potassium. The objective of this study was to assess the formulation of avocado juice with coconut water that could potentially reduce hypertension. The design of the study was an experimental with the degree of subsititution of coconut water as treatments. There were 3 kinds of treatment, i.e. F1 (75% avocado and 25% coconut water), F2 (50% avocado and 50% coconut water), F3 (25% avocado and 75% coconut water) and F0 (without coconut water but using water). Avocado juice product with 75% avocado substitution and 25% coconut water (F1) was a best formula determined by the hedonic test. This formula contained 68,48% (%w/w) water, 3,12% (%w/w) ash content, 4,45% (%w/w) fat content, 1,76% (%w/w) protein content, 21,07% (%w/w) carbohydrate content, 2163,8 (mg/kg) potassium content, 9,20% (%w/w) linoleic acid content, 1,11% (%w/w) linolenic acid content and 42,4% (%w/w) of total unsaturated fatty acid. This product could potentially reduce and prevent hypertension, because in one serving size (200cc) contain 432,76 mg of potassium (claim source of potassium).
Impacts of flooding on drinking water access in Dar es Salaam, Tanzania: implications for the Sustainable Development Goals
Authors: Smiley Sarah L. , Hambati Herbert
Published: March 2019

Floods are the most common type of natural disaster and they impact human health and well-being. In cities such as Dar es Salaam, Tanzania, it is the poorest residents who experience the worst impacts from flooding. Yet although the negative effects of floods on drinking water quality are known, there is little empirical evidence on how they affect water access more broadly. This paper uses interviews from Dar es Salaam's Kigogo Ward to understand perceptions of drinking water source changes during floods. It frames these perceptions in the Sustainable Development Goals, which seek to achieve universal and equitable access to water. Results show that households experience flooding both inside and outside the house and that these episodes impact water quality, accessibility, and availability. In particular, floods can increase contamination, force residents to wait to fetch water, and require them to walk through floodwater to reach water sources. Floods also cause them to discard stored drinking water. These results demonstrate the need for additional research on the impacts of floods on water access.

Authors: Zeitoun Rawan , Najjar Fadia , Wehbi Batoul , Khalil Alia , Fayyad-Kazan Mohammad , Dagher-Hamalian Carole , Faour Wissam H. , El-Makhour Yolla
Published: March 2019

Background:

Propolis is a resinous substance produced by bees and known to possess antioxidant, antimicrobial, antiproliferative and anti-inflammatory activities.

Objective:

This study is aimed at evaluating the in vivo and in vitro anti-inflammatory potential of the Crude Ethanolic Extract (CE) of Lebanese propolis and its Ethyl Acetate Fraction (EAF).

Method:

Chemical content of propolis was characterized using high-performance liquid chromatography and LC-MS/MS. COX-2 and iNOS protein expression, nitric oxide (NO) and prostaglandin (PGE2) release in LPS-activated RAW monocytes were achieved respectively by western blot and spectrophotometry. Antioxidant activity was evaluated by DPPH free radical scavenging assay. Measurement of paw thickness in carrageenan-induced paw edema in mice and pathologic assessment of inflammation in paw sections were used to judge the anti-inflammatory properties of propolis.

Results:

Pathology analysis revealed in the treated group significant reduction of immune cell infiltration and edema. Both extract and ethyl acetate fraction showed significant anti-inflammatory and antioxidant effects in LPS-treated RAW cells characterized by the inhibition of COX-2 and iNOS protein expression, as well as PGE2 and NO release. Chemical analysis of the crude extract and its ethyl acetate fraction identified 28 different compounds of which two phenolic acids and nine other flavonoids were also quantified. Ferulic acid, caffeic acid, chrysin, galangin, quercetin, and pinocembrin were among the most representative compounds.

Conclusion:

Lebanese propolis is rich in a various amount of flavonoids which showed promising antiinflammatory and antioxidant properties. Additionally, chemical analysis showed unique chemical compositions with the potential of identifying ingredients with interesting anti-inflammatory activities.

BACKGROUND

Currently, no medications are approved to treat core symptoms of autism spectrum disorder (ASD). One barrier to ASD medication development is the lack of validated outcome measures able to detect symptom change. Current ASD interventions are often evaluated using retrospective caregiver reports that describe general clinical presentation but often require recall of specific behaviors weeks after they occur, potentially reducing accuracy of the ratings. My JAKE, a mobile and Web-based mobile health (mHealth) app that is part of the Janssen Autism Knowledge Engine—a dynamically updated clinical research system—was designed to help caregivers of individuals with ASD to continuously log symptoms, record treatments, and track progress, to mitigate difficulties associated with retrospective reporting.

OBJECTIVE

My JAKE was deployed in an exploratory, noninterventional clinical trial to evaluate its utility and acceptability to monitor clinical outcomes in ASD. Hypotheses regarding relationships among daily tracking of symptoms, behavior, and retrospective caregiver reports were tested.

METHODS

Caregivers of individuals with ASD aged 6 years to adults (N=144) used the My JAKE app to make daily reports on their child’s sleep quality, affect, and other self-selected specific behaviors across the 8- to 10-week observational study. The results were compared with commonly used paper-and-pencil scales acquired over a concurrent period at regular 4-week intervals.

RESULTS

Caregiver reporting of behaviors in real time was successfully captured by My JAKE. On average, caregivers made reports 2-3 days per week across the study period. Caregivers were positive about their use of the system, with over 50% indicating that they would like to use My JAKE to track behavior outside of a clinical trial. More positive average daily reporting of overall type of day was correlated with 4 weekly reports of lower caregiver burden made at 4-week intervals (r=–0.27, P=.006, n=88) and with ASD symptoms (r=–0.42, P<.001, n=112).

CONCLUSIONS

My JAKE reporting aligned with retrospective Web-based or paper-and-pencil scales. Use of mHealth apps, such as My JAKE, has the potential to increase the validity and accuracy of caregiver-reported outcomes and could be a useful way of identifying early changes in response to intervention. Such systems may also assist caregivers in tracking symptoms and behavior outside of a clinical trial, help with personalized goal setting, and monitoring of progress, which could collectively improve understanding of and quality of life for individuals with ASD and their families.

Acercamiento al pensamiento político del general Felipe Ángeles
Authors: Guilpain Odile
Published: March 2019

Odile Guilpain analiza la compleja figura de Felipe Ángeles, afirma que los juicios sobre su actuación en la Revolución son contradictorios y sugiere que ello se debe a su simpatía hacia Villa y al desprecio que mostró a Carranza pues creía, como el primero, que la reflexión ética era el eje de la acción política; pero, también, defendió la Constitución carrancista. Mas el general, como señala la autora, fue dominado por su pasión en detrimento de la meditación usual de sus actos; no obstante, sus principios, donde la enseñanza de una moral democrática y socialista eran la base del engrandecimiento material, nunca dejaron de ser el motor de su actividad política.

Derivation and soliton dynamics of a new non-isospectral and variable-coefficient system
Authors: Xu Bo , Zhang Sheng
Published: March 2019

Under investigation in this paper is a new and more general non-isospectral and variable-coefficient non-linear integrodifferential system. Such a system is Lax integrable because of its derivation from the compatibility condition of a generalized linear non-isospectral problem and its accompanied time evolution equation which is generalized in this paper by embedding four arbitrary smooth enough functions. Soliton solutions of the derived system are obtained in the framework of the inverse scattering transform method with a time-varying spectral parameter. It is graphically shown the dynamical evolutions of the obtained soliton solutions possess time-varying amplitudes and that the inelastic collisions can happen between two-soliton solutions.

Published: March 2019

Deep mining is the most important way to obtain the resource in China now. Thus, rock is the main objective that the deep mining will encounter. Meanwhile, the frequent catastrophes in deep mining such as rock burst, coal and gas bursts, roof caving, water bursts, is the most serious problem. To have a better understanding of the mechanisms of fracture and the laws of damage evolution of rock and coal under deep environment, in this paper, the micro- and meso-scale method is employed to study the behavior of coal under different temperature, confining pressure and gas pressure. Then, the significance of the effect of temperature, confining pressure, and gas pressure on mechanical parameters is analyzed by using the ANOVA method. The fractal study of coal failure pattern by employing the SEM test and fractal dimension was carried out. The fractal dimension of coal fractures was calculated by using the box-covering method. Then, the effects of all factors on the fractal dimension of coal fractures were analyzed.

Published: March 2019

Background/Aim. Asthma is the most common chronic disease in children and adolescents and has shown an apparent increase in incidence in recent years. The first purpose of the study was to evaluate the influence of education about proper use of inhalers on quality of life in children with asthma. Secondly, we aimed to understand which aspects of quality of life in children with asthma can be significantly improved after education and to identify factors that may affect the level of that improvement. Methods. In this prospective, before-and-after interventional study, a total of 147 children with asthma were enrolled. The Pediatric Asthma Quality of Life Questionnaire (PAQLQ) was used to measure the functional problems that are most troublesome to children with asthma. We used the Asthma Control Test (ACT), based on a series of question about symptoms and daily functioning, to identify patients with poorly controlled asthma. Forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF) were also determined. Trained educators estimated patients? inhaler technique and collected questionnaire information. Results. Multivariate analysis of covariance indicated significant differences between PAQLQ and ACT scores which all were significantly higher after education about proper use of inhalers (p < 0.001). A number of children demonstrating a correct inhalation technique improved from 28 (19%) to 127 (86.4%) (p < 0.001). Asthma severity accounted for the largest proportion of variability PAQLQ and ACT scores (38.4%). Conclusion. Inhaler technique improvement contributes to better asthma control in children with asthma rather than to their quality of life. Asthma severity proved to be a major contributor to variations in PAQLQ and ACT scores and significant obstacle for quality of life improvement in children with asthma.

Background/Aim. Energy drinks (EDs) are widely used by athletes as ergogenic agents and Red Bull? is one of the most consumed EDs among them. The aim of this study was to determine the acute and chronic effects of Red Bull? on cardiodynamics and parameters of oxidative stress in physically trained rats. Methods. Rats were subjected to a swimming practice (1h a day, 5 days a week, for 4 weeks). They were divided into 4 groups: rats that did not consume ED either before swimming or prior to sacrificing; rats that did not consume ED before swimming but did consume ED 30 min prior to sacrificing; rats that consumed ED 30 min before every swimming training but did not consume ED prior to sacrificing; rats that consumed ED 30 min before every swimming training and 30 min before sacrificing. After sacrificing, the hearts of the rats were isolated and perfused according to the Langendorff technique. The parameters of cardiac function were recorded, and also the levels of prooxidants were measured in the coronary effluent during coronary autoregulation. Results. Acute administration of the ED had a positive inotropic effect (manifested as a significantly higher level of the maximum and minimum rate of pressure development in the left ventricle), while chronic administration affected the isolated increase in systolic left ventricular pressure. The prooxidative effect of the ED was observed, which was more pronounced in chronic consumption. Conclusion. The main conclusion of our study is that chronic consumption of ED changes the cardiovascular response and redox status in acute consumption ED.
Caught between Traditional Ways of Life and Economic Development: Interactions between Indigenous Peoples and an Oil Company in Numto Nature Park
Authors: Tysiachniouk Maria , Olimpieva Irina
Published: March 2019

The paper examines the conflict between indigenous people living in Numto Nature Park in the Khanty-Mansy region of Russia and the oil company Surgutneftegaz, which is trying to expand to new areas of the Park for industrial development. We analyse this conflict by looking at different perceptions concerning the threats and benefits underpinning the conflicting parties’ arguments. We show that the oil company, whose approach is based on the principles of benefit sharing, seeks to provide economic benefits as well as infrastructure to ensure development in the indigenous community. In contrast, the indigenous people in Numto prioritise environmental safety and the possibility of maintaining their traditional ways of life, which means eliminating the negative impacts of oil development on fisheries, reindeer herding and the general state of the environment. The study indicates that focusing on indigenous peoples’ and oil companies’ differences concerning perceptions of threats and benefits provides a better understanding of desirable benefit-sharing arrangements between oil companies and indigenous peoples in areas that have so far only been marginally affected by industrialisation and modernisation. This insight suggests that the introduction of community-centred perspectives emphasising cultural and environmental security in benefit-sharing policies in oil companies could improve practices. The analysis draws on interviews with members of the indigenous Nenets and Khanty peoples of Numto Park as well as representatives of Surgutneftegaz, NGOs, the regional administration and the Numto Park administration

In conducting its business, Islamic banking is based on a core product for the results of financing developed in musharaka and mudharabah financing products. This is what differentiates it from the conventional banking system based on interest. Economic sector in Indonesia is largely supported by micro, small and medium enterprises (SMEs) are proven to have the advantage of being able to survive during the economic crisis. So that this sector is very potential to be further developed through an appropriate policy and support from the appropriate institution anyway. Based on the principle of profit sharing financing system, Islamic banking is expected to help the development of SMEs optimally.
