Rheological and functional characteristics of starch and flour on different drying methods from Beneng Taro as sustainability products from agricultural in Banten

Beneng Taro is a type of taro found in Banten agricultural but has not been appropriately utilized. The drying process is critical since temperature changes will result in various properties. This research aimed to evaluate the rheology and functional characteristics of starch and flour made from Beneng Taro dried in the sunlight and hot air as sustainability products of it. This research contains the extraction of starch, the production of flour, and characterizing the starch and flour produced. The rheological characteristics of the flour and starch from the can be model using the Herschel-Bulkley. Starch and flour showed non-Newtonian shear-thinning flow characteristics, according to the flow behavior index. The difference in the consistency index value of flour is significant, where flour dried with sunlight shows a higher value. Both starch and flour show a sharp decrease in viscosity at low shear rates. The value of the starch and flour’s swelling power shown that cabinet drying was superior to drying outdoors in the sun. The solubility index undergoes the same phenomenon. In contrast to water and oil holding capacity, sun drying shows a higher value. Knowing the characteristics of the starch and flour produced can be applied as a food source.

Literary Semiotic Studies in the Novel Ringin Kurung

This study aims to analyze and describe the semiotic system that refers to the elements of icons, indexes, and symbols in Pak Mett's novel Ringin Kurung. The novel is a Javanese language novel that has a romance genre. It is a novel that has prominent elements, both intrinsic and extrinsic. The novel is interesting to study because it has elements of signs and implied meanings. The problem of understanding meaning in a complex literary work full of language games and elements of the author's creativity is not easy. So, this kind of study is needed. Analyzing the novel is a novelty that has never been done before. This study used a descriptive qualitative method. To be able to describe and analyze text in the form of words or sentences. The qualitative in question places more emphasis on the element of meaning. The approach used is Charles Sanders Pierce's semiotic theory. Literary semiotic theory interprets signs through icons, indexes, and signs. Sources of data from the novel Ringin Kurung by Pak Mett, journals, and books as references that support studies in research. The data collection technique is observation, namely observing and recording, followed by searching, reading, understanding, and concluding. The data analysis is thorough. From this research, it was found that there are signs in the form of icons, indexes, and symbols in Pak Mett's novel Ringin Kurung. There are icons, including plants (banyan trees), food (tempe and arem-arem), and places (square and hospital). The index is in the form of subordinate behaviour to the employer, polite behaviour index, firefly index, sultry index, and strategic index. As well as symbols, namely Ringin Kurung, vehicles (cars), goods (reclining chairs), blushing, fast breathing, and katresnan.

Phenotypic and genetic characterization of Africanized Apis mellifera colonies with natural tolerance to Varroa destructor and contrasting defensive behavior.

Africanized Apis mellifera colonies with promising characteristics for beekeeping have been detected in northern Argentina (subtropical climate) and are considered of interest for breeding programs. Integral evaluation of this feral material revealed high colony strength and resistance/tolerance to brood diseases. However, these Africanized honeybees (AHB) also showed variable negative behavioral traits for beekeeping, such as defensiveness, tendency to swarm and avoidance behavior. We developed a protocol for the selection of AHB stocks based on defensive behavior and characterized contrasting colonies for this trait using NGS technologies. For this purpose, population and behavioral parameters were surveyed throughout a beekeeping season in nine daughter colonies obtained from a mother colony (A1 mitochondrial haplotype) with valuable characteristics (tolerance to the mite Varroa destructor, high colony strength and low defensiveness). A Defensive Behavior Index was developed and tested in the colonies under study. Mother and two daughter colonies displaying contrasting defensive behavior were analyzed by ddRADseq. High-quality DNA samples were obtained from 16 workers of each colony. Six pooled samples, including two replicates of each of the three colonies, were processed. A total of 12,971 SNPs were detected against the reference genome of A. mellifera, 142 of which showed significant differences between colonies. We detected SNPs in coding regions, lncRNA, miRNA, rRNA, tRNA, among others. From the original data set, we also identified 647 SNPs located in protein-coding regions, 128 of which are related to 21 genes previously associated with defensive behavior, such as dop3 and dopR2, CaMKII and ADAR, obp9 and obp10, and members of the 5-HT family. We discuss the obtained results by considering the influence of polyandry and paternal lineages on the defensive behavior in AHB and provide baseline information to use this innovative molecular approach, ddRADseq, to assist in the selection and evaluation of honey bee stocks showing low defensive behavior for commercial uses.

Rheological characteristics of concentrated ternary gum mixtures with xanthan gum, guar gum, and carboxymethyl cellulose: Effect of NaCl, sucrose, pH, and temperature

Our goal was to investigate the effects of various conditions of media (NaCl, sucrose, pH, and temperature) on the steady and dynamic shear rheological properties of a concentrated ternary gum mixture system (1.0 wt%) containing xanthan gum (XG), guar gum (GG), and carboxymethyl cellulose (CMC). Regardless of the media conditions, all gum mixtures exhibited a high shear-thinning behavior with a low flow behavior index (<0.30). NaCl addition resulted in a decrease in the consistency index (K, 32.8–16.1 Pa·sn) and apparent viscosity at 50 s−1 (ηa,50, 1.00–0.75 Pa·s), as well as the elastic modulus (G′) and viscous modulus (G″) due to the charge screening effect. Similar result was observed with an increase in acidity of media. The presence of sucrose also induced the decrease in the ηa,50, K, G′, and G″ values of the ternary gum, but tan δ (G″/G′) decreased, indicative of higher weak gel-like properties. No effect of NaCl or sucrose addition on the temperature dependence of G′ values was observed, whereas pH adjustment was impacted. These results demonstrated that the presence of co-solute, the acidity of media, and temperature influenced the rheological properties of ternary gum, and in particular acid condition gave a great impact.

Effect of fungal isolates from different samples upon radionuclide behavior and environmental hazard indices during bioleaching process in Gabal Um Hamd, Um Bogma area, southwestern Sinai, Egypt

Two fungal species were isolated from the studied rock samples and identified morphologically as Aspergillus hollandicus and Penicillium citrinum. Bioleaching process was applied to W1, W2 and W3. The average concentration activity of 238U, 226Ra, 232Th, and 40K are 5134.03, 5708.64, 189.51, and 1456.8 BqKg−1, respectively. Radionuclide’s distribution in leach liquor, residual, and fungal adsorption were followed and environmental hazard indices (Raeq, Iγ, Hex, Hin, and ECLR) were calculated. From the observed outcomes, the isolated fungal strains have the potential to reduce the harmful effect up to 50% compared to the original. As a result, application of these fungal strains offers a potential strategy for environmental remediation of radionuclides.

Type a personality and nutritional behaviours of competitive basketball players

Introduction. Type A personality pattern (TAPP) is related to, among others, strong rivalry and struggle for achievements, which are features that fit into sports competition. One of the determinants of sports success is a proper diet. The aim of the study was to assess the relationship between the level of type A personality behavioural pattern and nutritional behaviours of basketball players. Materials and Methods. The study was conducted among 165 high-level basketball players. An author-designed nutritional behaviour questionnaire (according to the recommendations of the Food Pyramid for Swiss Athletes) and the Framingham Score in the Polish adaptation were used. Spearman's rank correlation and the Mann-Whitney U tests were applied for the analysis of the results. Results. The study confirmed that along with the increase in TAPP, the healthy eating behaviour index among basketball players increased, although it did not reach the level of statistical significance (p=0.080). Comparison of TAPP levels between groups that adhered to or disregarded particular nutritional recommendations showed that athletes limiting the consumption of non-recommended products (sweetened carbonated and non-carbonated beverages, energy drinks, fast food, and sweet and salty snacks) demonstrated a higher level of type A behaviours than those who did not follow these recommendations (p&lt;0.001). At the same time, however, athletes consuming fish at the recommended frequency and taking care of adequate hydration during training had lower levels of TAPP than those who did not follow these recommendations (p&lt;0.05). Conclusions. A positive relationship was found between the intensity of TAPP and the healthy eating behaviour index (without the level of statistical significance), but the results were not entirely unambiguous, which suggests the validity of further research.

The Polishing of Inner Wall on Medical Device Hole by Shear Thickening Abrasive Flow

To improve medical device hole inner wall quality and overcome issues of traditional abrasive flow methods—limited fluidity in small holes causing deformation due to high inner wall pressure, and slow processing with low viscosity abrasives—a new method called shear thickening abrasive flow polishing is suggested. It uses shear thickening fluid as the medium. By leveraging the Preston equation and fluid dynamics theory, this study establishes both an abrasive flow dynamics model and a material removal model for the shear thickening abrasive flow machining of small titanium alloy hole workpieces in medical instruments. Utilizing the COMSOL software, the flow field state of shear thickening fluid within small holes is examined under varying flow behavior indexes and flow velocities. The findings demonstrate that shear thickening fluid yields superior polishing effects compared to Newtonian fluid. Elevating the flow behavior indexes facilitates a higher material removal rate on the inner wall surface; however, excessively large flow behavior indexes diminish the uniformity of material removal, thereby hindering the attainment of a high-quality polished surface. Furthermore, excessively large flow behavior indexes can reduce fluidity and consequently lower the efficiency of the polishing process. Conversely, while maintaining a constant flow behavior index, increasing the flow velocity contributes to an enhanced material removal rate and improved polishing efficiency. Nevertheless, as the flow velocity rises, the uniformity of inner wall surface roughness diminishes, posing challenges in achieving a high-quality polished surface.

Use of oxidized potato starch as simultaneous fat and casein replacer in analogue mozzarella cheese-Ⅰ: Impact on rheological properties of cheese

The present study investigated the impact of native and oxidized potato starch as casein (15%) and fat (5%) replacer, both separately and simultaneously, in analogue mozzarella cheese (AMC). Oxidation of potato starch resulted in a more hydrophilic character with higher solubility compared to native potato starch which in turn altered casein hydration and resulted in increased stability of oil in water emulsion in cheese. The Fourier-transform infrared (FTIR) spectroscopy of cheese showed addition of new peak between (1635–1646) cm−1 owing to interactions between carbonyl group of oxidized starch and casein present in cheese suggesting better stability. Emulsion stability which is usually attributed to formation of spherical fat globules was also visible in scanning electro micrographs of oxidized starch containing cheese. The (G′ Vs. frequency) curve confirms psuedoplastic behavior of AMCs as flow behavior indices ranged between (0.231–0.258) similar to control AMC. Moreover, the cheese made with oxidized potato starch similar to control cheese showed two crossovers between storage and loss moduli during temperature sweep measurements which is associated with melting and then re-hardening of the cheese as temperature increases. This phenomenon was however absent in native starch containing AMCs. Thus, oxidized starch can better imitate casein and fat in mozzarella cheese.

Pressure transient behavior in an infinite reservoir with horizontal well: Non-Newtonian fluid flow in porous media

Many authors have worked on pressure transient analysis with non-Newtonian fluid flow in porous media. The existing work is limited to radial model in a vertical well, infinite conductivity hydraulic fracture, software simulation model and numerical model. Up to date, there has been no analytical work presented for horizontal well using power law model. Power law model best characterizes non-Newtonian rheological properties and the fluid flow in porous media. Today, horizontal well is widely being used in the exploitation of oil and gas in the industry; either as a producer or an injector. A reservoir where the flow of injected polymer solution during enhanced oil recovery and high viscosity crude oil exhibit non-Newtonian behavior, is better characterized with pressure transient with power law model. This fact has been established. In this study, we developed a 3-D power law model for analyzing pressure transient behavior in a reservoir with fluid flow that exhibits non-Newtonian behavior. The solution provided is semi-analytical and numerically inverted using Stehfest Algorithm. A step-by-step analytical procedure for analyzing each flow regime is developed. In order to validate the 3-D model, we developed type curves to match data provided from simulator in previous work. The step-by-step procedure was used to analyze an eclipse simulated data. We obtained consistent results that validated the analytical mathematical model.Additionally, the 3-D analytical model developed is applicable to composite reservoir with two distinct zones due to fluid and rock properties. The flow behavior index in both zones can either be 1.0 or less than 1.0. This is unique to this study.

Pasting and rheological properties of [formula omitted]- amylase treated proso millet starch as affected by hydroxypropylation and cross-linking in its granular and gelatinized state

The effect of hydroxypropylation and cross-linking on the pasting and rheological properties of α- amylase treated proso millet starch in granular as well as gelatinized state was investigated. The chemical modification of enzyme pre-treated starch showed significant changes (p < 0.05) in the swelling and solubility behavior. Amylose content and water binding capacity of the starches ranged from 16.72 to 21.26% and 1.23–1.53 g/g, respectively. The pasting profile of the modified starch gel (at 6% concentration) revealed a significant decline (p< 0.05) in peak viscosity. The Herschel-Bulkley model used to characterize the steady shear properties revealed that the flow behavior was non-Newtonian pseudoplastic. The flow behavior index (n) and consistency index (K) for starch pastes at 4% concentration ranged from 0.69 to 0.91 and 0.26 to 0.77 Pa.sn, respectively, whereas at 6% concentration, the values ranged from 0.45 to 0.71, and 0.46 to 11.35 Pa.sn, respectively. Dynamic rheological characteristics demonstrated that starch pastes exhibited dominant elastic behavior. The presence of hydroxypropyl groups was confirmed by FT-IR spectroscopy, with the noticeable band stretching at OH, CH, and CO. This modification approach can be exploited to prepare proso millet starch with tailored functional characteristics for desirable food applications.

Objective assessment of the association between frailty and sedentary behavior in older adults: a cross-sectional study

BackgroundGiven the inconsistent findings of the association between frailty and sedentary behavior in older adults, this cross-sectional study investigated the aforementioned association using four different frailty criteria and two sedentary behavior indices in older adults.MethodsData from older adults (age ≥ 65 y) who participated in health examinations or attended outpatient integrated clinics at a medical center in Taipei, Taiwan, were collected. Frailty was measured using the modified Fried Frailty Phenotype (mFFP), Clinical Frailty Scale in Chinese Translation (CFS-C), Study of Osteoporotic Fractures (SOF) index, and Clinical Frailty-Deficit Count (CF-DC) index; sedentary behavior was assessed with a waist-worn accelerometer. Adjusted linear regression ascertained the association between frailty and both sedentary behavior outcomes.ResultsAmong the 214 participants (mean age 80.82 ± 7.14 y), 116 were women. The average total sedentary time and number of sedentary bouts were 609.74 ± 79.29 min and 5.51 ± 2.09 times per day, respectively. Frail participants had a longer total sedentary time (odds ratio [OR]: 30.13, P = .01 and 39.43, P < .001) and more sedentary bouts (OR: 3.50 and 5.86, both P < .001) on mFFP and CFS-C assessments, respectively. The SOF index revealed more sedentary bouts among frail than in robust participants (OR: 2.06, P = .009), without a significant difference in the total sedentary time. Frail participants defined by the CF-DC index were more likely to have frequent sedentary bouts (OR: 2.03, P = .016), but did not have a longer total sedentary time.ConclusionsRegardless of the frailty criteria adopted, frailty was positively associated with the number of sedentary bouts per day in older adults. A significant correlation between frailty and total sedentary time was detected only with mFFP and CFS-C indices. Further research may target decreasing the sedentary bouts in older adults as a strategy to improve frailty.

Effects of high hydrostatic pressure on antimicrobial protein stability and the rheological and shelf-life properties of donkey milk.

The effects of high hydrostatic pressure (HHP) and heat treatments on antimicrobial protein stability and on the physico-chemical, microbiological, rheological and shelf-life properties of donkey milk were investigated. Although heat treatment at 75°C for 2 min resulted in 1.50 log CFU ml-1 microbial inactivation, losses in activities of lysozyme (58%) and lactoferrin (82%) were observed due to whey protein denaturation. By contrast, HHP application at 400 MPa caused lower enzyme activity losses (22 and 37% respectively) whilst maintaining a significant reduction of microbial load (1.80 log CFU ml-1). Color analyses showed that the lightness values of all samples decreased during storage. Higher flow consistency (viscosity) and lower flow behavior indexes were observed in heat-treated samples compared to untreated and HHP-treated ones, which can be explained by advanced protein denaturation during heat-treatment. The results suggest that HHP is a more suitable process than heat treatment for preservation of donkey milk within the conditions studied.

Numerical investigation on the interaction of an oscillating bubble with the interface of a non-Newtonian fluid

The dynamics of an oscillating bubble near a liquid–liquid interface is a complex multiphase flow problem due to the highly nonlinear interaction, such as interface fragmentation and bubble tearing. When one of the liquid mediums is non-Newtonian, its constitution would significantly influence both the bubble motion and the interface evolution. In this study, a numerical model is established based on the Eulerian finite element method with the non-Newtonian fluid described by the Herschel–Bulkley model. The numerical model is validated by comparing with experimental results for a non-spherical pulsating bubble at a water–oil interface and the analytical solution for the laminar flow of non-Newtonian fluids in a circular tube. According to the simulation and analysis with different case parameters, our findings suggest that the non-Newtonian fluid forms a crater when squeezed by the bubble, and the downward jet can penetrate the bubble and further deepen the crater. As the distance parameter increases, the crater gradually disappears or even bulges. Furthermore, the yield shear stress can give non-Newtonian fluid plastic properties similar to a solid, effectively reducing the bubble's pulsation and jet load. Additionally, the flow behavior index n comes from the power-law model for non-Newtonian fluids and significantly impacts the jet's impact process. When n≤1, the crater is likelier to become funnel-shaped, whereas when n &amp;gt; 1, it is likelier to become bullet-head-shaped. In addition to enhancing the bubble's nonsphericity, the reduction in Reynolds number also weakens the crimp deformation of the interface. When the distance parameter is zero, the larger the buoyancy parameter and the less deformable the non-Newtonian fluid, the easier the bubble to split by the annular jet.

Determining the flow transition from laminar to turbulence using simple spin-echo magnetic resonance techniques

We have recently introduced a methodology to determine the average velocity and flow behavior index of laminar pipe flow of a power-law fluid using simple magnetic resonance (MR) techniques. In general, MR techniques are noninvasive and capable of working on optically opaque fluids. Knowledge of the average velocity and flow behavior index provides the information needed to reconstruct the flow velocity profile. However, as the flow velocity increases, the flow will begin to develop turbulence. For pipe flow of a particular fluid, the velocity profile is flatter in the center of the pipe at turbulent flow rates compared with laminar flow. An effective flow behavior index can approximate the time-averaged velocity profile, as the Reynolds number increases, as a fluid transitions from laminar to turbulent flow. Here, we show the results of testing the utility of such a simplification in monitoring that transition. For the present study, Reynolds numbers ranged from approximately 490 to 6800, which corresponds to flow rates of 200 to 2750 ml/min and average velocity of 5 to 80 cm/s. We found that visual inspection of the data would be sufficient to determine the state of the flow. With some external knowledge of the flow rate, the shape of the time-averaged velocity profile and eddy diffusivity can be estimated (and potentially also an average fluid particle acceleration).

Stability and Rheological Behavior of Mayonnaise-like Emulsion Co-Emulsified by Konjac Glucomannan and Whey Protein.

The aim of this work was to study the physical stability and rheological properties of an oil-in-water emulsion stabilized by a konjac glucomannan-whey protein (KGM-WP) mixture at a konjac glucomannan concentration of 0.1-0.5% (w/w) and a whey protein concentration of 1.0-3.0% (w/w). The droplet size, microstructure, stackability, flow behavior, and viscoelastic properties were measured. The experimental results showed that with an increase in KGM and WP concentrations, the droplet size (D4,3) of the emulsion gradually decreased to 12.9 μm, and the macroscopic performance of the emulsion was a gel-like structure that can be inverted and resist flow and can also be extruded and stacked. The static shear viscosity and viscoelasticity generally increased with the increase of konjac glucomannan and whey protein concentration. Emulsions were pseudo-plastic fluids with shear thinning behavior (flow behavior index: 0.15 ≤ n ≤ 0.49) and exhibited viscoelastic behavior with a storage modulus (G') greater than their loss modulus (G″), indicating that the samples all had gel-like behavior (0.10 < n' < 0.22). Moreover, storage modulus and loss modulus of all samples increased with increasing KGM and WP concentrations. When the concentration of konjac glucomannan was 0.3% w/w, the emulsion had similar rheological behavior to commercial mayonnaise. These results suggested that the KGM-WP mixture can be used as an effective substitute for egg yolk to make a cholesterol-free mayonnaise-like emulsion. The knowledge obtained here had important implications for the application of protein-polysaccharide mixtures as emulsifiers/stabilizers to make mayonnaise-like emulsions in sauce and condiments.

Numerical analysis of finite bearing operating under non-Newtonian lubricant and flow turbulence effect

The purpose of this work is to evaluate the combined influence of turbulence and shear-thinning/shear-thickening lubricant on the steady-state characteristics of hydrodynamic journal bearings. The modified Navier–Stokes equation for linear turbulence and non-Newtonian (shear-thinning as well as shear-thickening aspect) lubricants are solved using a finite element method to acquire load capacity, attitude angle, friction coefficient variable, total oil flow, and temperature rise variable for distinct combined values of the flow behavior index and Reynolds number. This work utilizes the Navier–Stokes equation with Ng–Pan's linear turbulence and shear-thinning/shear-thickening lubricant models, which is very helpful in predicting the performance characteristics of hydrodynamic bearings under harsh industrial operating conditions. The results show that the combined presence of non-Newtonian lubricant and turbulence in the flow significantly affects the steady-state performance parameters of such type of bearing compared to existence of individual presence of turbulence and non-Newtonian lubricant in the clearance space. This work helped to provide better insight into the operation of journal bearings in a severe environment owing to the high speed and changes in the nature of lubricant.

Lifting and drainage of Sisko fluid film with surface tension: A theoretical study on stationary points and thickness of uniform film

This paper accords with the theoretical study of lifting and drainage of Sisko fluid film on a vertically upward moving cylinder with surface tension. The flow on cylinder is induced by the upward motion of the cylinder, gravity and surface tension gradient. The resulting nonlinear ordinary differential equation is solved for a series form solution by making use of the Adomian decomposition method (ADM). Expressions for the flow variables like velocity, volume flow rate, shear stress and surface tension are derived. Positions of stationary points and thickness of uniform film are computed numerically in MATHEMATICA. The inverse capillary number C, Stokes number [Formula: see text], Sisko fluid parameter [Formula: see text] and fluid behavior index n emerged as flow control parameters. The study showed that the positions of stationary points relocate towards the surface of the cylinder by the increase of C and [Formula: see text] while their positions relocate towards the fluid–air interface with increasing [Formula: see text] and n. Thickness of uniform film decreases when the values of C and [Formula: see text] are increased whilst it increases with the increase of [Formula: see text] and n. Analogy between the Newtonian fluid and the Sisko fluid’s shear thinning and shear thickening behaviors for positions of stationary points, thickness of uniform film and surface tension is also made.

On the analysis of time-dependent drainage of Sisko fluid film slowly down a vertical belt

Theoretical analysis of time-dependent drainage of Sisko fluid film slowly down a stationary vertical belt is presented in this paper. Employing [C. Gutfinger and J. A. Tallmadge, AIChE J. 10, 774 (1964)] approach the subsequent nonlinear partial differential equation is simplified. The Adomian decomposition method is then used to solve the simplified nonlinear partial differential equation to obtain the analytic expression for velocity. The analytic expressions for volume flow rate, shear stress, average film velocity, surface profile and film mean thickness are also derived. It is delineated that the velocity decreases by an increment in the Sisko fluid parameter and time while it increases by an increment in the fluid behavior index. The elevation of the Sisko surface profile decreases when the values of Sisko fluid parameter are increased, whereas it increases when the values of fluid behavior index and time are increased. The variable film thickness of four different lubricating greases is estimated by using experimental values of material constants and fluid behavior index [A. W. Sisko, Ind. Eng. Chem. Res. 50, 1789 (1958) and M. A. Delgado et al., Chem. Eng. Process. 44, 805 (2005)]. Furthermore, the flow variables studied for the Sisko fluid are also studied for the Newtonian fluid, and comparisons between both are provided.

Rheology-dependent mass diffusion characteristics of high-solids anaerobic co-digestate of food waste and sewage sludge

Rheology-dependent mass diffusion characteristics of high-solids anaerobic co-digestion (HS-AcoD) systems of food waste (FW) and sewage sludge (SS) are important inputs for system optimization modeling but have not yet been clearly elucidated. Results indicated that the effective diffusion coefficient of digestate (Deff.) decreased from 8.40 × 10−10 m2·s−1 to 5.99 × 10−11 m2·s−1 as the total solids (TS) increased from 10.14% to 18.12%. Higher values of the yield stress, viscosity, consistency index, critical modulus and energy of cohesion but lower values of the flow behavior index were obtained with increasing TS content. A satisfactory correlation was obtained between the rheograms and Herschel–Bulkley model. Higher proportion surface water in the high TS digestate explained the decrease of Deff. and the deterioration of rheological properties. Finally, the relationship between the rheological parameters and Deff. could be modeled by empirical equations with forms of power functions. The results of this study can guide the design and operation of HS-AcoD systems to enhance mass transfer during FW and SS disposal processes.
