Anisotropic-Wormhole-Network Generation in Carbonate Acidizing and Wormhole-Model Analysis Through Averaged-Continuum Simulations
Authors: Schwalbert Mateus Palharini , Zhu Ding , Hill A. Daniel 
Published: October 2018

Summary
The optimal design of matrix-acidizing operations in carbonate reservoirs is a discussion in progress. Although several models are available to the industry for predicting wormhole propagation, most of them are not sufficiently practical to be used in real treatment designs, or they were developed to represent coreflood data and cannot be simply scaled up to represent wormhole formation in complex well geometries. This problem is addressed by Furui's wormhole-propagation model (Furui et al. 2012a), which is a modification of the Buijse and Glasbergen (2005) empirical correlation, including a scaleup procedure to represent field carbonate-acidizing operations using laboratory coreflood data. It is a practical engineering tool that can be used for treatment designs in horizontal wells, including barefoot and perforation-cluster completions in fairly isotropic and homogeneous reservoirs.
In this work, an analysis of Furui's model is performed, including the effect of anisotropy (x, y, z permeability) in the carbonate reservoir. The analysis includes both radial and elliptical wormhole propagation that forms from an openhole completion, and the spherical or ellipsoidal wormhole propagation that emerges from each perforation in a perforation-cluster completion that makes the use of a limited-entry technique for achieving an acceptable acid placement.
The development is made using extensive 3D numerical simulations with a two-scale continuum model and a finite-volume method to represent the dissolution of the porous medium. The numerical model is tuned to represent real results through matching experimental coreflood data and dissolution patterns.
Conclusions are obtained regarding both isotropic and anisotropic formations. In isotropic formations with the radial propagation of wormholes, simulations indicate that a number from four to six wormholes propagates radially in each plane. When the propagation is spherical, simulations result in a number from 16 to 24 wormholes, propagating spherically from the point of acid injection.
In anisotropic formations, the radial stimulated zone might become an elliptical stimulated zone, depending on the acid-injection rate and the permeability-heterogeneity magnitude. The major axis of the elliptical stimulated zone coincides with the direction of a higher permeability and a longer permeability-correlation length, and it is longer for larger acid-injection rates. In the same manner, the spherical wormhole-propagation pattern might become an ellipsoidal stimulated zone in anisotropic formations.

Published: October 2018

The article covers the outcomes of the empiric research devoted to the revelation of subjective life way picture formation among servicepersons in different spatiotemporal conditions of professional activities. It verifies the hypothesis of interrelation between personality’s subjective life way picture and professional specifics of person’s position and actualization environment. Professional medium could affect spatiotemporal and life-purpose characteristics of life way, person’s temporal orientation, correlation of time loci in person’s world picture.The findings prove the fact that spatiotemporal characteristics of professional activities conditions promote the development of person’s peculiar methods of time arrangement and formation of subjective life way picture. The article shows that the representatives of the model groups, mirroring different spatiotemporal organization of professional activities, demonstrate diverse perception and content of the past, present and future; dissimilar strategies of one’s own life way apprehension in the context of time transpective; varied directivities into life spheres. The results of the research are applicable for the organization of psychological work with servicepersons in different conditions of professional activities.

Abstract
Nitrate removal during anaerobic ammonium oxidation (anammox) treatment is a concern for optimization of the anammox process. This study demonstrated the applicability and long-term stability of the coupled anammox and hydrogenotrophic denitrification (CAHD) process as an alternative method for nitrate removal. Laboratory-scale fixed bed anammox reactors (FBR) supplied with H2 to support denitrification were operated under two types of synthetic water. The FBRs showed simultaneous NH4-N and NO3-N removal, indicating that the CAHD process can support NO3-N removal during the anammox process. Intermittent H2 supply (e.g. 5 mL/min for a 1-L reactor, 14/6-min on/off cycle) helped maintain the CAHD process without deteriorating its performance under long-term operation and resulted in a nitrogen removal rate of 0.21 kg-N/m3/d and ammonium, nitrate, and dissolved inorganic nitrogen removal efficiencies of 73.4%, 80.4%, and 77%, respectively. The microbial community structure related to the CAHD process was not influenced by changes in influent water quality, and included the anammox bacteria ‘Candidatus Jettenia’ and a Sulfuritalea hydrogenivorans-like species as the dominant bacteria even after long-term reactor operation, suggesting that these bacteria are key to the CAHD process. These results indicate that the CAHD process is a promising method for enhancing the efficiency of anammox process.

Published: October 2018

Purpose:To evaluate changes in serum fatty acids, metabolic profile and inflammation markers after a dietary intervention of 15g of walnuts and 15g of almonds for 8 weeks in obese subjects,Patients and Methods:We studied a total of 48 sedentary obese grade I subjects (13 men and 35 women). Anthropometric measures, body composition, serum glucose, lipid profile, insulin, lipocalina-2, high sensitivity C-reactive protein (hsCRP), adiponectin, and fatty acids profile were analyzed at the baseline and after dietary intervention.Results:The adiponectin (30.4%, p = 0.007), and lipocalin-2 concentrations (17.9%, p = 0.014), and total Polyunsaturated Fatty Acids (PUFAs) percentage (1.6% p = 0.040) significantly increased after the intervention; particularly the eicosapentaenoic acid and docosahexaenoic acid percentages were increased marginally. A significant decrease in saturated fatty acids levels (3%, p = 0.001), in particular the C:14, C:16, in total cholesterol (6.7%, p = 0.01), LDL (11.4%, p = 0.002) levels, and in all adiposity measures (weight, waist circumference, hip circumference, BMI and fat mass, p < 0.0001) was found. The effect size was large for all adiposity measures, except for BMI as well as for adiponectin which was moderate.Conclusion:The intake of almonds and walnuts to short-time may improve significantly the metabolic profile and decrease adiposity.
Mitigating Academic Distress: The Role of Psychological Capital in a Collectivistic Malaysian University Student Sample
Authors: Chua Ryan Yumin , Ng Yin Lu , Park Miriam Sang-Ah 
Published: October 2018

Background:
The emphasis of education within the collectivistic Malaysian culture has exposed Malaysian university students to high levels of academic stressors. The experience of stress that stems from the experience of such stressors can be positive (eustress) or negative (distress). However, the presence of adaptive abilities to academic stress may influence the experience of stress. The present study examines psychological capital as the adaptive ability to academic stress among a collectivistic Malaysian university student sample.

Methods:
This cross-sectional study was conducted with a total of 183 students from a university in Malaysia.

Findings:
Analyses showed that university students with high academic distress did not predict low academic performance; while, university students with high academic eustress predicted high academic performance. Psychological capital was found to mitigate the influence of academic distress on academic performance but not on the influence of academic eustress on academic performance.

Conclusion:
The study debunked the common misconceptions about academic stress. It highlighted that the experience of eustress and the presence of psychological capital may be an important resource for students’ stress coping.

Published: October 2018

Background:Anemia is an important public health problem affecting all age groups of the population. The objective of this study was to identify the risk factors associated with anemia among women of childbearing age in Rwanda and map their spatial variation.Methods:The 2014/15 Rwanda Demographic and Health survey data was used and the structured logistic regression model was fitted to the data, where fixed effects were modeled parametrically, non-linear effects were modeled non-parametrically using second order random walk priors and spatial effects were modeled using Markov Random field priors.Results:The prevalence of anemia among non-pregnant women of reproductive age was 18.9%. Women from the households which use water from the unprotected well had a higher risk of having anemia than a woman from the household where they use water piped into dwelling or yard. The risk of anemia was higher among underweight women and women living in households without toilet facilities. The anemia was less pronounced among the women using contraception, literate women, women from the households which use a bed net and living in rich households.Conclusion:The findings from this study highlighted the districts with the highest number of anemic women and this can help the policymakers and other public health institutions to design a specific programme targeting these districts in order to improve the health status and living conditions of these women. The findings also suggest an improvement of toilet facilities, bed net use and source of drinking water in affected households.
Identifying Behaviors Predicting Early Morning Emotions by Observing Permanent Supportive Housing Residents: An Ecological Momentary Assessment
Authors: Nandy Rajesh R , Nandy Karabi , Hébert Emily T , Businelle Michael S , Walters Scott T 
Published: October 2018

Background
Behavior and emotions are closely intertwined. The relationship between behavior and emotions might be particularly important in populations of underserved people, such as people with physical or mental health issues. We used ecological momentary assessment (EMA) to examine the relationship between emotional state and other characteristics among people with a history of chronic homelessness who were participating in a health coaching program.

Objective
The goal of this study was to identify relationships between daily emotional states (valence and arousal) shortly after waking and behavioral variables such as physical activity, diet, social interaction, medication compliance, and tobacco usage the prior day, controlling for demographic characteristics.

Methods
Participants in m.chat, a technology-assisted health coaching program, were recruited from housing agencies in Fort Worth, Texas, United States. All participants had a history of chronic homelessness and reported at least one mental health condition. We asked a subset of participants to complete daily EMAs of emotions and other behaviors. From the circumplex model of affect, the EMA included 9 questions related to the current emotional state of the participant (happy, frustrated, sad, worried, restless, excited, calm, bored, and sluggish). The responses were used to calculate two composite scores for valence and arousal.

Results
Nonwhites reported higher scores for both valence and arousal, but not at a statistically significant level after correcting for multiple testing. Among momentary predictors, greater time spent in one-on-one interactions, greater time spent in physical activities, a greater number of servings of fruits and vegetables, greater time spent interacting in a one-on-one setting as well as adherence to prescribed medication the previous day were generally associated with higher scores for both valence and arousal, and statistical significance was achieved in most cases. Number of cigarettes smoked the previous day was generally associated with lower scores on both valence and arousal, although statistical significance was achieved for valence only when correcting for multiple testing.

Conclusions
This study provides an important glimpse into factors that predict morning emotions among people with mental health issues and a history of chronic homelessness. Behaviors considered to be positive (eg, physical activity and consumption of fruits and vegetables) generally enhanced positive affect and restrained negative affect the following morning. The opposite was true for behaviors such as smoking, which are considered to be negative.

Authors: Sorin Matei , Gabi-Mirela Matei , Monica Dumitrașcu 
Published: October 2018

Abstract
Soils from rural zones with high natural value (HNV) agriculture systems are an important source of beneficial microbial species that can be useful for various biotechnological purposes, such as transfer of suppressiveness against plant pathogens from suppressive to disease-inducing soils by using inoculation with antagonistic selected strains.
The main goal of the paper was to present the results of the research carried out on strains isolated from soil microbial populations in HNV agriculture system (Mureș county, Romania) responsible for specific suppressiveness against soil-borne phytopathogens. The dual culture method was used for assessing the mechanisms involved in antagonism against a plant pathogenic strain from genus Fusarium.
The global microbial activity measured as soil respiration was intense. Total counts of bacteria and fungi estimated by dilution plate were also high.
The community of heterotrophic aerobic bacteria included 13 species. Associations of fluorescent pseudomonads and actinomycetes were dominant and presented antagonistic activity against Fusarium.
Twenty fungal species presented cellulolytic capability evidenced by growth on culture media with cellulose as sole source of carbon. Over cellulolytic capacity, the selected isolate of Trichoderma viride presented antagonistic activity against pathogenic Fusarium strain. Both biochemical mechanism and hyperparasitism were evidenced as involved in its antifungal activity.

Published: October 2018

Abstract
The presence of oil hydrocarbons and salts in soils has as consequence the poor growth of plants due to the low availability of nutrients caused by unappropriate water regime, increased soil toxicity and the deterioration of soil structure. The present research has as main purpose the improvement of the bean plants (cultivar UNIDOR) growth and to stimulate microbial activity in rhizosphere using various natural stimulators and fertilizers (AMALGEROL,VERMIPLANT, POCO, IGUANA and FORMULEX) in greenhouse experiments on oil-polluted soil from Icoana farm, Olt county. The total counts of microorganisms (heterotrophic aerobic bacteria and filamentous fungi) were estimated by dilution plate method. The global microbial activity was measured as soil respiration by substrate-induced respiration method. Total bean plants biomass accumulation significantly increased under the influence of natural stimulators and fertilizers added (excepting IGUANA) when compared to untreated control. The best results were recorded for VERMIPLANT. Natural products induced activation of physiological activities of soil microbiota reflected in increased values of CO2 released by respiration, lower levels of colonization with phytopathogenic species, the domination of fluorescent pseudomonads, actinomycetes and cellulolytic fungi, too. The particular aspect of paper circular chromatograms reflected qualitative differences between rhizosphere soils determined by the effect of treatments with natural stimulators and fertilizers.

Published: October 2018

Abstract
Formwork system is a significant constituent and a basic requirement for high-rise cast-in-place rein­forced concrete buildings. Usually, the builders are con­fronted with the decision to choose the safe, optimum number of levels of shores/reshores for a predetermined safety factor and given grade of concrete, giving due con­sideration to the cost of formwork system. In this study, MATLAB program is developed to calculate the load dis­tribution between the interconnected slabs and levels of shore/reshore of a slab formwork based on a simplified method. This program is further modified by incorporat­ing genetic algorithm for the optimization of cost of con­struction for high-rise building. The cost of level of shores and reshores per floor is defined as a function of cycle time which directly reflects the increase in the cost of construction. Various combinations of shore and reshore levels with several grades of concrete for various safety factors are checked to minimize the cost of construction. The optimization equation is solved using genetic algo­rithm considering appropriate constraints to practically ensure feasible solutions. The case of one level of shores and numerous levels of reshores is better than one level of reshores and numerous levels of shores. The result of certain combination of shore and reshore levels is not the same when the level numbers are reversed. A comparative study is carried out to check the optimum cost for various safety factors. The program is useful for the designers to decide the levels of shores and reshores with minimized cost without compromising the safety of construction.

Published: October 2018

Abstract
Purpose: Recent studies show that lowest bidder tech­nique is mainly used in developing countries such as India to award a contract. It has been demonstrated that the lowest bid is not always the accurate one and can lead to cost overruns and time extensions amongst other prob­lems. The aim of this study was to investigate the critical factors impacting contractor’s efficiency in Indian con­struction projects. Research approach: A survey was sent to participants of construction projects awarded by the government with the lowest bidder technique in Uttar Pradesh, India. For further research, snowball sampling was used, and struc­tured interviews were conducted amongst experienced managers and engineers of these projects on both client’s and contractor’s side.Findings: It was observed that, to a greater extent, the delays were caused due to contractor’s opportunistic behaviour. The main findings are that new bidding meth­odologies are to be tested as they can lead to the choice of a more accurate and realistic bidder. In addition, subjec­tive evaluation components, such as schedule and work­force, should be reflected in contract award methods in addition to the cost criteria. Further studies should be per­formed on the choice of contract awarding methodology based on the project size and type. Originality value: The researcher’s focus was to analyze the influence of contracting methodologies and factors affecting contractor’s performance in lowest bid award project, where this is an area of least focus amongst researchers in the Indian subcontinent.
Information or Evidence? Abandoning Imaginary Worlds for Blockchains in Health Technology Assessment
Authors: Langley Paul 
Published: October 2018

Commentaries published in INNOVATIONS in Pharmacy over the past 2 years have made the case that, as a basis for formulary decision making, the construction of imaginary modeled worlds fails to meet the standards of normal science. As such, they should be rejected as a basis for decision-making. While their proponents argue that imaginary constructs are key sources of information for formulary decisions, the fact is that the claims made from those models are impossible to validate. Indeed, they were never intended to be validated. Claims for product performance should be presented in evidentiary terms. That is, they should be credible, evaluable and replicable. If the commitment to imaginary worlds in technology assessment is to be abandoned a key requirement is for platforms that allow claims to be assessed in real time and in a timeframe that is meaningful to decision makers. Recent developments in blockchain technology offer the prospects for platforms that meet criteria for claims assessment.
