Published: March 2021

The application of tertiary recovery techniques through chemical injection (CEOR) is in full development in the mature oil fields of Argentina. An experimental study of nanofluids intended for enhanced oil recovery is presented in this work. A polyacrylamide solution prepared in brine with addition of silica nanoparticles was used as the focus of the study. Dynamic sweep tests of the displacement fluids in a laboratory-scale triaxial cell using a standard Berea sandstone cores that simulates the formation of the reservoir allow the calculation of parameters related to its injectivity, which take into account damage to the formation and blockade of poral throats , such as the resistance factor (FR), the residual resistance factor (FRR), the inaccessible pore volume (VPI) and the dynamic retention of the nanofluid (RD). The injection of the nanofluid has not produced an increase in the damage of the porous medium, so it is potential for its application in the displacement of crude oil.

Authors: Demiray Engin
Published: March 2021

Oyster mushroom slices were dried using hot air dryer. The lovastatin content in oyster mushroom slices during drying was evaluated at 45, 55 and 65˚C. The first-order reaction model adequately described degradation of lovastatin. In this study, the modeling of the drying process was also performed. Four mathematical models were fitted to the experimental data. The performance of these models is evaluated by comparing the coefficient of determination, root mean square error and reduce chi-square between the observed and predicted moisture ratio. The Page model gave the best results for describing drying of oyster mushroom slices.

Authors: Mansour Mohammed , Abd-Elsalam Emad , Ahmed Sameh , Mohamed EMAN F
Published: March 2021

This paper studies the effect of fractional order and how it effects on the distribution of heat (isotherms) and sites of the thermally buoyant part of the walls on the flow pattern (streamlines) in an enclosure filled with Cu-water nanofluid. The conformable fractional derivative are used to transform the dimensionless governing equations to fractional equations in dimensionless form by substituting derivatives of an integer order with fractional derivatives of order α. Equations are solved numerically by finite difference method for several values of the fractional parameter α.The results show that α control in the movement of fluid and the velocity in the cavity. Also we see that Nusselt number increases when α reduces

Authors: Maciel Dariela Candela , Ingaramo Alejandra Patricia , Perez Sergio Marcelo , Heluane Humberto
Published: March 2021

Citrus production is one of the main agro-industrial activities in Tucuman, Argentina, with a value in 2017 estimated at US$1,178 millions. Production of lemon juice concentrate requires the use of evaporation systems which are critical for the water and energy usage in all process industries. Precise knowledge of process variables is therefore extremely important for evaluation of the efficiency, economic parameters, etc. of the whole plant. In this work, data reconciliation and gross error detection were performed on data collected from the lemon juice concentration unit of an industrial plant located in Tucuman, Argentina. From reconciled data, the overall heat transfer coefficients of the four-effect evaporation line were calculated. In addition, a mathematical model was developed to predict the overall heat transfer coefficients. The parameters of the model were fitted to the experimental data and to the reconciled plant.
ASPECT RATIO EFFECTS ON BOTTOM HEATED 2D CAVITY USING ENERGY STREAMLINES AND FIELD SYNERGY PRINCIPLE
Authors: Rani Hari Ponnamma , Vekamulla Narayana , Rameshwar Yadagiri , Starchenko Sergey Vladimirovich
Published: March 2021

In the present work free convective air flow in the two-dimensional cavity with three different aspect ratios (AR) are investigated using direct numerical simulation. The bottom wall is assumed to be kept at a uniform higher temperature than that of the top wall and the other two vertical walls are assumed to be thermally insulated. The computations are conducted for Rayleigh number (Ra) values from 103 to 106. Convective schemes are compared and Self Filtered Central Differencing Scheme is used to discretize convective term. Parallel computing MPI code is adapted to run the simulations. An attempt has been made to gather the visualization techniques such as streamlines, isotherms, energy streamlines and field synergy principle to analyse the flow behaviour inside the cavity. When Ra is small, the vertical energy streamlines are observed in the cavity. As Ra further increased, the free energy streamlines observed at the boundary and the trapped energy streamlines at the centre in the horizontal direction. For a fixed Ra, and increasing AR, the average synergy angle increases. This indicates synergy or the coordination between velocity magnitude and temperature field gets decreased and leads to the growth of heat transfer rate. The field synergy principle implies by enhancing the synergy between the velocity vector and temperature gradient.

Authors: Fischer Carlos Daniel , Costa André Hemerly L. , Bagajewicz Miguel J
Published: March 2021

In this article we compare results from different heuristics approaches for the design of VLE separation vessels. In addition, we present an MILP model that embeds the aforementioned heuristics and considers the discrete nature of the geometric variables. We show that different heuristics render different results. In addition, while results from heuristics and MILP often coincide sometime, departures take place. Finally, we show that straight enumeration is viable option for stand-alone design.
UNSTEADY MHD FLOW OF RADIATING CASSON FLUID THROUGH A PERMEABLE CHANNEL WITH SLIP, BUOYANCY FORCE AND HEAT SOURCE
Authors: Verma Om Prakash , Makinde Oluwole Daniel , Monaledi R. L.
Published: March 2021

Analytical investigation is performed into an unsteady Magnetohrodynamics mixed convective Casson fluid flow and heat transfer characteristics with thermal radiation, wall slip, heat source and buoyancy force in a permeable vertical channel. The fluid is injected into the left wall of the channel and sucked out at right wall. The governing momentum and energy balance equations are achieved and tackled analytically. The effects of numerous thermophysical parameters on the temperature profiles, velocity, Nusselt number as well as skin friction are presented graphically and discussed qualitatively. The results show that a temporal decline in the pressure gradient causes both the temperature and fluid velocity to decrease. Moreover, the enhancement in heat transfer due to wall injection/suction also causes the skin friction to decrease.

Published: March 2021

Wastewaters containing biocides constitute an increasing environmental pollution concern. In this work, the feasibility of implementing a pre-treatment based on the Fenton process to minimize the negative impact of biocide compounds, such as benzalkonium chlorides (BAC), on the activated sludge system was studied. The behavior of the microbial community in the presence of a BAC solution untreated (BAC100) or pre-treated by homogeneous Fenton oxidation (BAC100/HF) was analyzed. The addition of BAC100 to the activated sludge system caused a deleterious effect. The cellular lysis process caused a 30% decrease in biomass concentration. The inhibition of respiratory activity was 73%. In contrast, BAC100/HF caused no significant decrease in the biomass concentration or detectable inhibition of the respiratory activity. Besides, the consumption of easily oxidizable products was observed. Results indicated that the homogeneous Fenton process as a pre-treatment of wastewaters containing BAC could become a feasible alternative to protect active biomass in biological treatment systems.

Published: March 2021

Textile waste water containing dyes, surfactants, salts and other contaminants represent a challenge for the selection and design of treatment processes due to the stability of some of its components. Advanced oxidation processes (AOPs) are attractive alternatives to partially or totally degrade dyes and other persistent pollutants using relatively compact devices to perform water treatment. To test the efficiency of these technologies it is necessary to count with laboratory made solutions that can match the characteristics of a typical textile waste waters effluent. In this work the application of two AOP, ozonation and photo-Fenton, to the treatment of textile effluents are compared, using a specially design model solution. The effect of typical textile wastewater composition on the treatment efficiency is discussed. Higher decoloration efficiencies were obtained with both AOPs tested in this work, being slightly higher with ozonation. TOC was only partially removed, being more efficient photo-Fenton than ozonation.
SIMULATION-BASED OPTIMIZATION FOR THE SCHEDULING OF ELECTIVE SURGERY UNDER UNCERTAINTY AND DOWNSTREAM CAPACITY CONSTRAINTS
Authors: Durand Guillermo Andrés , Bandoni J. Alberto
Published: March 2021

The generation of an optimal schedule of elective surgery cases for a hospital surgery services unit is a well-known problem in the operations research field. The complexity of the problem is greatly compounded when uncertainties in the parameters are considered and is an issue that has been addressed in few works in the literature. Uncertainties appear in surgery durations and the availability of downstream resources such as surgical intensive care units (SICU), presenting large deviations from their expected value and impacting in the performance of the scheduling process. The technique presented here addresses the uncertainties in the optimal scheduling of a given set of elective surgery cases by means of simulated-based optimization. The main advantage of this approach over previous works is that detailed systems’ simulations can be constructed without losing computational performance, thus improving the robustness of the scheduling solution.

Authors: Trasarti Andres , Gonzalez Eduardo , Nieres Pablo , Apesteguia Carlos
Published: March 2021

This work studies the production of high-value compounds by the cross-metathesis of methyl oleate (MO) with ethylene, cinnamonitrile and cinnamaldehyde using the 2nd generation Hoveyda-Grubbs complex (HG) as catalyst, either dissolved in toluene or supported on silica. Reactions were carried out in batch reactors between 313 and 343 K. The yield to cross-metathesis products (YC-M) for the MO cross-metathesis with cinnamonitrile and cinnamaldehyde increased with the initial molar reactant ratio (RCN/MO, RCA/MO), reaching YC-M values of 82% and 95%, respectively, at R = 7. No catalyst deactivation took place during the 400-min catalytic runs.  The liquid-phase cross-metathesis of MO with ethylene (ethenolysis) was performed over HG(10%)/SiO2 catalysts, producing 1-decene and methyl 9-decenoate, a valuable intermediate for the synthesis of pheromones. At RC2/MO = 2.5, the selectivity to ethenolysis products was 77% at 82% MO conversion. The MO self-metathesis was the only side reaction observed in all the catalytic tests.

Published: March 2021

The replacement of monomers derived from petrochemical sources by biopolymers like proteins, together with the development of new materials with improved properties, have an increasing importance in industrial applications. In this context, the synthesis of acrylic-casein hybrid latexes was investigated through a low environmental impact strategy, such as the surfactant-free emulsion polymerization, with the aim of producing new industrial adhesives. Different aspects of the synthesis of hybrid latexes were addressed, such us i) the use of variable content of protein; ii) the control of grafting degree between polymers, using native casein (without chemical modification) or functionalized casein, and iii) the employment of a chain transfer agent to reduce molecular weights of the acrylic polymer. The effect of the analyzed variables on the polymerization kinetics, the degree of compatibility between polymers, and the application properties of the produced latexes as adhesives were investigated.

Authors: Izli Nazmi , Polat Ahmet
Published: March 2021

In this study, the effect of ultrasound pre-treatment on quality parameters (colour, rehydration, pH and °Brix) of potato samples was investigated. In addition, drying kinetics of potato samples were formed and 10 mathematical models were applied to experimental data to select the best thin-layer drying model in drying processes. Two different slices of potato samples (2 and 4 mm) were ultrasound pre-treated for 0, 20 and 40 min before drying. Drying was carried out in a modified oven at 60 and 70 °C at an air velocity of 1 m/s. As the ultrasound pre-treatment time applied to the samples increased, the drying time of the product decreased. The drying rate decreased with increasing product slice thickness. A decrease in yellowness (b*) values was observed with the effect of drying conditions. Rehydration values of potatoes under all drying conditions ranged from 2.856 to 2.640. The highest pH value was determined in potato samples dried at 60 °C with a thickness of 4 mm without ultrasound pre-treatment. The closest °Brix value to the fresh product was observed in 2 mm thick potato samples dried at 70 °C and treated with ultrasound for 40 min. In this study, it has been determined that ultrasound pre-treatment can be used as a different method for drying potato with hot air.

Authors: Kvapil Maria Florencia , Chaillou L.L. , Qüesta A.G. , Mascheroni Rodolfo
Published: March 2021

Mass transfer during osmotic dehy-dration (OD) of pumpkin cubes was studied as a function of sample size and composition and con-centration of sucrose dehydrating solution. Models of Azuara and Hawkes & Flink were adjusted to the experimental data and optimal dehydrating conditions could be specified. For equal solutes concentration, higher weight losses were reached for smaller size samples. The addition of 2% NaCl increased Water Loss (WL) and lowered Solids Gain (SG) for the solution of higher sucrose con-tent. Prediction capacity of the simplified models was very good under the tested working conditions. In brief, OD can be optimized using 1 cm side cu-bes dehydrated in binary or ternary solutions at the higher sucrose content (55ºBx), maximizing WL and minimizing SG.

Published: March 2021

The aim of this study was to evaluate the changes in the fatty acid composition and microstructure of goat cheeses during 80 days of ripening. Creole goat milk from the Quebrada de Humahuaca was used to produce cheeses. Samples were taken 5 hours and 10, 20, 30, 40, 60 and 80 days after preparation. The composition of fatty acids for each period was determined by gas chromatography. The changes in the matrix cheese were observed using an electron microscopy. The medium-chain fatty acids and the unsaturated fatty acids decreased during the whole study but at two different velocities. They became established at the end of the ripening time, which is coincident with the decrease in fatty globule sizes: 2–4.6 µm at the beginning, 300 ηm at 30 days of ripening, and 140 ηm at the end of the maturation time studied.

Purpose: The number of clinical trials conducted by the industry has increased significantly for the period 2014-2016. They have produced advances in disease prevention, treatment, and rehabilitation for many diseases. This was the main reason to carry a study on the association between certain demographic indexes and the number of clinical trials in the European economic area. Proving a correlation between those two variables could lead to additional research pursued by the industry during the feasibility phase of each study in order to have higher and quicker enrollment for the success of the clinical trial. Materials/Methods: Three demographic factors were considered to have some importance on the clinical trial enrollment – the number of population, life expectancy at age 65 and Disability-Adjusted Life Years (DALY). The numbers were processed with Spearman‘rho, and the read of the results shows a correlation to be present for the number of population and life expectancy at age 65. Results: There is a correlation between the number of clinical trials opened for enrollment of patients and certain demographic indexes, which could lead to favorable conditions for trial conduct in the different countries of EEA. Conclusions: Studying in advance if some demographic factors are significant for conduct of clinical studies is something new that could be used by the industry to avoid the wastefulness of a clinical project.
What's in a “Timber Fiction”? The Significance of Wood in Dickens's Our Mutual Friend
Authors: Hamdi Saber
Published: March 2021

In a novel where wood and human life are closely bound, woodenness is Dickens's metaphor for a perversely narcissistic self that spreads pygmalionist petrification to ever larger levels of interpersonal relations, thus giving rise to cultural atavism at a time when progress is heralded as the epoch's credo. The taking over of bodies and spaces by wood points to the propagation of an unnatural mentality nourished by a pathological clinging to a fetishized past as a compensation for the present feeling of lack and amputation. But far from being blocked, the possibility of regeneration requires a protean subject that undergoes castration in the form of an empathetic opening unto the other, one that carries the reader outside the double logic of narcissistic projection and introjection.

Published: March 2021

A survey of AP English Literature and AP English Language exams administered over the past two decades reveals that nineteenth-century British literature—especially novels of this era—is underrepresented compared to texts from other literary historical periods. At the same time, a range of recent or relatively recent fiction, television shows, and film depicts teenagers embracing Victorian texts, particularly the novels of George Eliot. This unexpected enthusiasm for literature published two centuries ago, however, is even more evident in high school English classes today. This article includes six accounts of the successes that secondary school English teachers have had in motivating their students to read nineteenth-century fiction that seemed destined to gather dust on the shelves of their schools' bookrooms.

Jay Gatsby, Scion of America
Authors: Kuhnle John
Published: March 2021

Published ninety-five years ago, The Great Gatsby today continues to yield surprises. This article examines elements of F. Scott Fitzgerald’s artistic development between his first two novels, This Side of Paradise and The Beautiful and Damned, and his third. First exhibited in The Great Gatsby, his mature style lies in linking a basic story to a transcendent theme, providing meaning to the narrated experience. Influenced by the groundbreaking work of his contemporaries James Joyce and T. S. Eliot, Fitzgerald elevated the story of Jay Gatsby to become a metaphor for the cultural history of America. In reviewing the evolution of the “SCHEDULE” that James Gatz writes in the flyleaf of his copy of Hopalong Cassidy in 1912, this article argues that this seemingly minor device is the armature of the novel and an index to Gatsby’s life.
