Identification and prediction of inter-individual differences in cognitive training trajectories : a growth mixture modelling approach
Creators: name: Wolf, AP
Publisher: name: University Of Tasmania
Year: 2023

description: There is emerging evidence of inter-individual differences in cognitive training responsiveness. Conventional statistics do not adequately address heterogeneity and longitudinal performance trajectories. Generalised growth mixture modelling (GGMM; Muthen, 2004) was utilised to identify and predict heterogeneous longitudinal cognitive performance trajectories following training. Specific and generalised effects of training were examined. Baseline characteristics such as age, sex and proxies for cognitive reserve were also explored as predictors of trajectories. Data from 315 community-dwelling older adults (age 55‚Äö-85 years) from the Active Cognitive Enhancement (ACE) Program training study were analysed. Short-term (VM) and long-term verbal memory (LTVM) and executive functioning (EF) were tested using the Rey Auditory Verbal Learning Test (RAVLT) and the CogState Ltd Groton Maze Learning Test (GMLT) at baseline and at 3-, 6- and 12-month follow-ups. Generalised growth mixture modelling demonstrated High, Moderate, and Low performance classes for memory performance. High and Low classes were identified for executive function. Also identified were demonstrable performance trajectory gains in the trained individuals of the Low class for executive function, those performing at a low normative level at baseline (Cohen's d = 2.23). These results offer a novel contribution to the literature. Gains by those trained in the Low performing VM and LTVM classes' performance trajectories were also shown (Cohen's d = 4.48 and 1.38, respectively). However, the experimental participants were compared to a small number of controls (n = 2) thus no meaningful training effects on memory were identified. The GGMM models therefore demonstrated that the multidomain ACE cognitive training program produced some generalised cognitive improvement in healthy older adults, albeit to limited extent. Age and estimated premorbid IQ (a proxy for cognitive reserve) predicted Low EF performance trajectories compared to High class performances. Trained individuals were more likely to be older and have lower levels of estimated pre-morbid IQ. Individuals who demonstrated executive function performance gains were less likely to demonstrate verbal memory trajectory gains. These findings suggest distinct responses to training in different cognitive domains and/or distinctive inter-individual responses to elements of the multi-domain training program. Caution with interpretation of GGMM labels and predictive factors identified is necessary, given their relativity to the cohort. With this approach, current theories including compensation, magnification, 'Use It or Lose It', plasticity, flexibility, and cognitive reserve are supported. Application of GGMM can also further facilitate development of individually tailored and cost effective cognitive training programs.

description: Current peacebuilding interventions aiming at addressing the causes of violent conflicts in the eastern DR Congo have been focusing on the ‘local community’ level as a scale of intervention. This study employed the multi-sited ethnographic methodological approach to understand why peacebuilding interventions have not so far succeeded in addressing the root causes of violence. Empirical findings drawn from this study demonstrate that, by focusing on land, power and identity issues as the driving forces of violence in Masisi (North Kivu), not only peacebuilding interventions have reduced the complexity of these issues to the ‘local’ level at the expense of other levels (provincial, national and regional), but have also ignored the role of powerful individuals (string pullers) in conflict dynamics as well as networks of interests that continue to challenge the current peace initiatives. This study used the politics of scale approach to demonstrate how land, power, and identity are multi-scalar issues rather than only local ones, and to analyze how these issues continue to provide avenues to some powerful individuals in the process of the scales’ production. Acknowledging the relevance of the politics of scale in the approaches we currently know might be a way forward to peacebuilding paradigms shift.
Gravitational recoil: effects on massive black hole occupation fraction over cosmic time

description: We assess the influence of massive black hole (MBH) ejections from galaxy centres, due to the gravitational radiation recoil, along the cosmic merger history of the MBH population. We discuss the 'danger' of the recoil for MBHs as a function of different MBH spin/orbit configurations and of the host halo cosmic bias, and on how that reflects on the 'occupation fraction' of MBHs. We assess ejection probabilities for mergers occurring in a gas-poor environment, where the MBH binary coalescence is driven by stellar dynamical processes, and the spin/orbit configuration is expected to be isotropically distributed. We contrast this case with the 'aligned' case. The latter is the most realistic situation for 'wet', gas-rich mergers, which are the expectation for high-redshift galaxies. We find that if all halos at z>5-7 host a MBH, the probability of the Milky Way (or similar size galaxy) to host a MBH today is less than 50%, unless MBHs form continuously in galaxies. The 'occupation fraction' of MBHs, intimately related to halo bias and MBH formation efficiency, plays a crucial role in increasing the retention fraction. Small halos, with shallow potential wells and low escape velocities, have a high ejection probability, but the MBH merger rate is very low along their galaxy formation merger hierarchy: MBH formation processes are likely inefficient in such shallow potential wells. Recoils can decrease the overall frequency of MBHs in small galaxies to ~60%, while they have little effect on the frequency of MBHs in large galaxies (at most a 20% effect).

Non-anticoagulant derivatives of heparin for the management of asthma : distant dream or close reality?
Creators: name: Shastri, Madhur
Publisher: name: University Of Tasmania
Year: 2023

description: Unfractionated heparin (UFH) belongs to a class of linear, highly sulfated, acidic polysaccharides known as glycosaminoglycans. Low-molecular-weight heparins (LMWHs) are modified heparin fragments with a molecular weight range of 2000 to 8000 Da. LMWHs are prepared by either chemical or enzymatic depolymerisation of UFH. In clinical practice, UFH is largely replaced by LMWHs because of their improved pharmacokinetic profiles as decreased risk of side effects. Heparins (UFH and LMWHs) are comprised of heterogeneous mixture of anticoagulant and non-anticoagulant fractions. Much recently, these polysaccharides have shown to possess anti-inflammatory effects and such effects are strongly influenced by degree of sulfation, distribution of sulfate groups and chain length. Interestingly, the potential anti-inflammatory activities of heparins, such seen in asthma, are reported to be because of the interactions between their non-anticoagulant molecules and various biological molecules. Numerous studies highlight the role of heparins in the management of inflammatory disorders including asthma. Asthma is a common chronic inflammatory condition of the conducting airways. It is estimated that approximately 300 million people worldwide suffer from asthma and it is associated with severe morbidity, and sometimes even mortality. Asthma is known to be driven by various inflammatory cytokines including interleukin-(IL)-4, IL-5, IL-6, IL-8, IL-13 and tumor necrosis factor-alpha (TNF-˜í¬±). The current drug modalities used for the management of asthma are reported to have a number of drawbacks and it is also estimated that up to 10% asthmatic patients have difficult-to-treat asthma that is often resistant to first line treatment with inhaled corticosteroids. Some recent in vivo studies have confirmed that heparins possess significant anti-asthmatic activity. However, the use of heparins for the management of asthma is hindered by the risk of bleeding associated with their anticoagulant fractions. For example, in one study, administration of LMWH resulted in massive haemorrhage in a patient with inflammation. Apart from this, the investigation of anti-inflammatory effects of LMWH is challenging because these activities are expressed with high LMWH concentrations where the anticoagulant effects predominate. Therefore, the overall aim of the study was to confirm that a LMWH (e.g. enoxaparin and dalteparin) can inhibit various inflammatory mediators involved in the pathogenesis of asthma with a view of identifying non-anticoagulant fraction(s) of the parent LMWH responsible for its anti-asthmatic effect.

Does epibiosis facilitate the invasion success of marine benthic invertebrates?
Creators: name: Leonard, K
Publisher: name: University Of Tasmania
Year: 2023

description: The theoretical understanding of invasion success is linked to a variety of drivers including enemy release, facilitation, and competitive ability. Within the marine environment, any bare solid substrate is quickly colonised making free‚ÄövÑvp space for settlement a limited resource. Consequently, the living surfaces of many species are subjected to the constant threat from overgrowth and/or epibiosis. Epibiosis presents a mechanism that eliminates the need to find bare space while increasing overgrowth success by settling on competitors. The ability of non-indigenous species (NIS) to see and use more types of space as free‚ÄövÑvp space may confer a competitive advantage to these species and requires greater investigation. As such the basis of this thesis is to explore epibiosis in NIS and native marine community assemblages. Theoretically, native species have co-evolved defence mechanisms against epibiosis, whereas they are na‚àövòve against epibiosis by NIS (and vice versa). Epibiosis is common, however a systematic review revealed a lack of information comparing native and NIS interactions, especially where the outcome of epibiosis was mortality. The pattern of epibiosis was examined within naturally assembled communities to understand native:NIS epibiotic interactions. Recruitment phenology was contrasted with settlement preferences and epibiotic pressures of both native and introduced species in communities of varying ages in northern Tasmania. Native species were found to have more interactions than expected with natives than with NIS. In contrast, NIS demonstrated no significant preferences between NIS, native and bare substrates: Thus, they see all space as available, compared to native species that show a preference for type of space to settle upon. Building on this, ex situ manipulative experiments were used to examine pairwise interactions controlling for propagule pressure, propagule arrival time and environmental factors hypothesised in the literature to influence recruitment and subsequent settlement success. The experimental outcomes demonstrate that native species experience greater epibiotic settlement by both native and NIS, whereas NIS were relatively free of epibiotic load. The multiple lines of evidence used in this dissertation have illustrated fundamental differences between marine native species and marine NIS, reinforcing the view that NIS are opportunistic settlers using a greater suite of substrates as available space than native species. Moreover, given that epibiosis generally comes at a cost to basibionts, a reduced epibiotic load on NIS compared to native competitors, infers a competitive advantage to NIS.

Natural Image Coding in V1: How Much Use is Orientation Selectivity?

description: Orientation selectivity is the most striking feature of simple cell coding in V1 which has been shown to emerge from the reduction of higher-order correlations in natural images in a large variety of statistical image models. The most parsimonious one among these models is linear Independent Component Analysis (ICA), whereas second-order decorrelation transformations such as Principal Component Analysis (PCA) do not yield oriented filters. Because of this finding it has been suggested that the emergence of orientation selectivity may be explained by higher-order redundancy reduction. In order to assess the tenability of this hypothesis, it is an important empirical question how much more redundancies can be removed with ICA in comparison to PCA, or other second-order decorrelation methods. This question has not yet been settled, as over the last ten years contradicting results have been reported ranging from less than five to more than hundred percent extra gain for ICA. Here, we aim at resolving this conflict by presenting a very careful and comprehensive analysis using three evaluation criteria related to redundancy reduction: In addition to the multi-information and the average log-loss we compute, for the first time, complete rate-distortion curves for ICA in comparison with PCA. Without exception, we find that the advantage of the ICA filters is surprisingly small. Furthermore, we show that a simple spherically symmetric distribution with only two parameters can fit the data even better than the probabilistic model underlying ICA. Since spherically symmetric models are agnostic with respect to the specific filter shapes, we conlude that orientation selectivity is unlikely to play a critical role for redundancy reduction.

Sufficient conditions under which the unique solution of the inverse problem exists, are formulated in terms of the Weyl function and a procedure to solve the inverse problem is given. The case of the generalized Weyl functions of the form $ϕ(λ)\exp\{-2iλD\}$, where $ϕ$ is a strictly proper rational matrix function and $D=D^* \geq 0$ is a diagonal matrix, is treated in greater detail. Explicit formulas for the inversion of the corresponding semiseparable integral operators and recovery of the Dirac-type system are obtained for this case.

description: To describe the positive and negative impacts of spasticity across different neurological disorders using the Patient Reported Impact of Spasticity Measure (PRISM), deduce any associations between severity of spasticity and its impact, and assess for differences across diagnostic subgroups. PRISM, a spasticity-specific quality of life questionnaire validated in patients with spinal cord injuries, was given to 97 follow-up patients attending a spasticity clinic prior to symptom assessment using the REsistance to PAssive movement Scale (REPAS). Patients described a minor level of positive impact and a marked negative impact in the domains of “Psychological Agitation,” “Daily Activities,” “Need for Assistance/Positioning” and “Social Avoidance/Anxiety.” Spasticity severity was, in general, a poor predictor of perceived impact, although severity and localisation of spasticity was modestly correlated with “Need for Assistance/Positioning” and “Social Embarrassment” levels. Despite comparable levels of spasticity severity, people with MS expressed a more substantial impact across some PRISM domains than did patients in other groups. PRISM can be useful to assess the impact of spasticity in various neurological conditions although further validation studies are needed.Implications for RehabilitationThe localisation of spasticity in both legs or the right arm can produce a significant impact on ‘Need for Assistance/Positioning’ and ‘Social Embarrassment’.People with MS may experience a greater impact of spasticity than those with other neurological conditions, particularly in the domains of Social Avoidance/Anxiety and Psychological Agitation.Coexisting factors such as anxiety, depression, fatigue and pain should be investigated together with spasticity.PRISM can assist in goal setting and treatment of people with spasticity secondary to different neurological conditions.

Nail biting and related health issues : perspectives of health professionals and nail biters
Creators: name: Le, TT
Publisher: name: University Of Tasmania
Year: 2023

description: Nail biting is a common oral habit, which is usually considered as developmental and harmless. In severe cases, from a health perspective, nail biting may lead to health problems such as skin infections or minor tissue damage, dental issues, bacterial infection, and alveolar destruction. However, in many societies, nail biting is frequently not taken seriously as a pathological condition, and this may increase the possibility of the emergence of serious health issues. In terms of causes and treatment measures for nail biting, there has been an extreme lack of research evidence, especially in the medical literature. In an attempt to cast more light on this under-investigated issue of nail biting, the present study was conducted with a special focus on its possible causes, associated health problems and treatment methods from the perspective of nail biters, parents of nail biting children and health professionals. The research endeavoured to seek answers to the following research questions. 1. What are the views of nail biters and parents of nail biting children in Tasmania, Australia on the possible causes, associated health issues, and treatment of nail biting? 2. What are the views of Australian health professionals on the possible causes, associated health issues, and treatment of nail biting? 3. What are implications and recommendations for Australian parents and health professionals in dealing with nail biting among children? A mixed methods design was utilised in the present study, with the use of questionnaires in the quantitative phase and semi-structured interviews in the qualitative phase. Regarding the questionnaires, data were collected from a total of 145 participants, including 65 health professionals and 80 nail biters or parents of nail biters. For the semi-structured interviews, the sample consisted of 23 past and current nail biters, and 14 health professionals.

description: We report on the observation of reverse Doppler effect in backward spin waves reflected off of surface acoustic waves. The spin waves are excited in a yttrium iron garnet (YIG) film. Simultaneously, acoustic waves are also generated. The strain induced by the acoustic waves in the magnetostrictive YIG film results in the periodic modulation of the magnetic anisotropy in the film. Thus, in effect, a travelling Bragg grating for the spin waves is produced. The backward spin waves reflecting off of this grating exhibit a reverse Doppler shift: shifting down rather than up in frequency when reflecting off of an approaching acoustic wave. Similarly, the spin waves are shifted up in frequency when reflecting from receding acoustic waves.

description: The role that a CEO’s personality plays in corporate outcomes is a topic of considerable interest, particularly the relation between narcissistic CEOs and performance. Common perception is that CEO narcissism is highly prevalent, and considerable research suggests that narcissism is associated with worse outcomes. The majority of studies, however, are based on “unobtrusive” methods that do not directly measure the CEO’s personality through a validated questionnaire but instead on indirect evidence thought to be indicative of narcissism. In this Closer Look, we test some basic assumptions about the relation between narcissism and corporate outcomes using a sample of CEOs whose personality is formally assessed by long-time directors who know and have worked closely with that CEO. While most of the research into narcissism and outcomes is negative, we find unexpected associations. We ask: Would the results of existing literature be replicated if CEOs were subject to a valid personality evaluation? What contribution does a CEO’s personality have to outcomes, and how does it manifest itself through strategy, risk, and culture? How much discussion does the board have about the personality of their CEO? What actions do they take when they identify personal tendencies that might be of concern? Are narcissists better at corporate “window dressing” than their less narcissistic peers?

description: We investigate the effect of dust on spiral galaxies by measuring the inclination-dependence of optical colours for 24,276 well-resolved SDSS galaxies visually classified in Galaxy Zoo. We find clear trends of reddening with inclination which imply a total extinction from face-on to edge-on of 0.7, 0.6, 0.5 and 0.4 magnitudes for the ugri passbands. We split the sample into "bulgy" (early-type) and "disky" (late-type) spirals using the SDSS fracdeV (or f_DeV) parameter and show that the average face-on colour of "bulgy" spirals is redder than the average edge-on colour of "disky" spirals. This shows that the observed optical colour of a spiral galaxy is determined almost equally by the spiral type (via the bulge-disk ratio and stellar populations), and reddening due to dust. We find that both luminosity and spiral type affect the total amount of extinction, with "disky" spirals at M_r ~ -21.5 mags having the most reddening. This decrease of reddening for the most luminous spirals has not been observed before and may be related to their lower levels of recent star formation. We compare our results with the latest dust attenuation models of Tuffs et al. We find that the model reproduces the observed trends reasonably well but overpredicts the amount of u-band attenuation in edge-on galaxies. We end by discussing the effects of dust on large galaxy surveys and emphasize that these effects will become important as we push to higher precision measurements of galaxy properties and their clustering.

Botanical imperialism : the cultivated landscape as carpet
Creators: name: Green, HL
Publisher: name: University Of Tasmania
Year: 2023

description: This project is germinated by my immersion in rural Northern Tasmania where I began cultivating heirloom vegetable species as fieldwork and became aware of culturally inherited empirical attitudes towards nature. Fostering a connection between botany and textiles, revealed as pivotal instruments of empirical global trade, I encountered the notion of botanical imperialism through researching Indian textile traditions, focusing on the Mughal 'flower' carpets from the 16th and 17th centuries. Through this research I developed an interest in economic botany, and became aware of the appropriation, control, and economic use of plant cultigens in the context of the capitalist system. The concept of cultivated landscape as carpet is established to relate fieldwork to broader concerns about commercial cultivation, providing a platform for environmental commentary. The materiality of carpet, a dense, heavy, easily transportable fabric, blanketing what lies beneath historically associated with wealth and power -metaphorically coalesces with seemingly disparate fields of knowledge, textiles, botany, ecology, empire and trade, that this research intersects. Early studio works -gouache drawings and woven tapestry -compare imagery from fieldwork to empirical types of botanical representation found in art, science and commerce. Abstract botanical symbols and compositional elements such as centre/edge and shifting scale combine to express the manipulation and transportation of economic botany across global boundaries. The resultant depictions appeared constrained by intellectualised conceptions of the cultivated landscape and act as a catalyst for and are integral to the development and understanding of ensuing work. This journey positions my practice as contributing to a cultural record of plant conservation in relation to visual artists using botanical representation in their work such as Andrew Seward, Lauren Black, Ruth Johnstone and Chris De Rosa; as a platform for environmental commentary such as Fiona Hall, Janet Laurence, Ken and Julia Yonetani; and those responding intuitively to place and making, such as John Wolseley, G.W Bot and Julie Mehretu. My deep experiential, sensorial connection to land revealed the potency and reverence of seed. Influenced by transformative life events -birth and death-my art making and thinking processes shifted to become intrinsically linked to fluid, intuitive responses to cultivation, comprising networks of interconnected systems, akin to woven fabric. In subsequent drawing works I made and embedded plant material in paper, creating indexical traces of dried seed heads, with fibrous matter, oil stains, soil remnants remaining as textural impressions. Appearing light as air and heavy as ground, with the trace rendered grey and left bare, the liminal space in the drawings evokes the transformational state of being, encapsulated within making, cultivation, and life cycles contained within this project.
Studies in the genus sporidiobolus

description: The synthesis of Sporobolomyces odorus dikarya is confirmed. Some of the morphological and physiological characteristics of strains of Sporidiobolus and of Sporobolomyces dikarya were observed and compared. These included optimum temperatures for mycelial and total growth, standard cytological and colonial descriptions, ability to assimilate carbon compounds, and ultraviolet survival curves. Attempts were made to dedikaryotize mycelia by ultraviolet irradiation and by chemical means; these were unsuccessful. Various techniques were used in an attempt to induce germination of resting spores. Presoaking in distilled water followed by incubation on water agar at room temperature proved successful for Sporobolomyces odorus spores which germinated by the formation of ustilaginaceous promycelia. Primary sporidia of this strain gave rise to non-mycelial colonies, thus completing the life cycle of this organism. A new species, Sporidiobolus microsporus, is described. The dimensions of the yeast cells and ballistospores average 2 X 8μ. The dikaryon is almost identical to that of other species, but the resting spores are typically intercalary. Carbon source assimilation by the new species differed from that of other species of the genus. Attempts to germinate resting spores of Sporidiobolus microsporus were unsuccessful.

description: Traditional sample preparation requires substantial resources and time, both adversely affecting the economical and ecological accounts of an analytical workflow. To address the dearth of greenness, this work used field-enhanced and electrokinetic sample injection from capillary electrophoresis (CE) for off-line sample preparation. This approach, referred to as electrophoretic concentration (EC) and simultaneous EC and separation (SECS), relies on the use of an electric field to transfer charged analytes from a mL-volume of aqueous sample to 20 ˜í¬¿L of acceptor electrolyte immobilised in a micropipette. The use of a conductive hydrogel to facilitate a zero net-flow inside a fused silica capillary is described and then explored for EC of charged analytes. The hydrogel was crucial to the success of EC, because it supported voltage application and retained the acceptor electrolyte in the micropipette. Anionic dyes and pollutants from drinking water as well as cationic drugs from wastewater were concentrated in less than 50 min and sensitive analysis by CE was achieved. The EC setup was then modified for SECS and implemented on an eight channel device to increase the sample throughput. Herbicides fortified in river water and beer samples were used to study SECS in combination with chromatographic and electrophoretic separation employing UV and mass spectrometric detection. Analyte enrichments of up to a factor of 337 in less than 45 min were achieved which enabled low ng/mL detection. Compared to solid-phase extraction, SECS reduced the sample preparation time by 94% and resource consumption by 99%. EC and SECS in combination with stacking-CE showed potential for trace analysis and all the SECS and EC acceptor electrolytes were directly compatible for analytical separation without the need for time-consuming steps. EC and SECS were organic solvent-free, rapid and simple sample preparations which were complying with the principles of Green Analytical Chemistry.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.
Dosimetric equivalence of non-standard high dose rate (HDR) brachytherapy catheter patterns

description: Purpose: To determine whether alternative HDR prostate brachytherapy catheter patterns can result in improved dose distributions while providing better access and reducing trauma. Methods: Prostate HDR brachytherapy uses a grid of parallel needle positions to guide the catheter insertion. This geometry does not easily allow the physician to avoid piercing the critical structures near the penile bulb nor does it provide position flexibility in the case of pubic arch interference. On CT data from ten previously-treated patients new catheters were digitized following three catheter patterns: conical, bi-conical, and fireworks. The conical patterns were used to accommodate a robotic delivery using a single entry point. The bi-conical and fireworks patterns were specifically designed to avoid the critical structures near the penile bulb. For each catheter distribution, a plan was optimized with the inverse planning algorithm, IPSA, and compared with the plan used for treatment. Irrelevant of catheter geometry, a plan must fulfill the RTOG-0321 dose criteria for target dose coverage. Results: Thirty plans from ten patients were optimized. All non-standard patterns fulfilled the RTOG criteria when the clinical plan did. In some cases, the dose distribution was improved by better sparing the organs-at-risk. Conclusion: Alternative catheter patterns can provide the physician with additional ways to treat patients previously considered unsuited for brachytherapy treatment (pubic arch interference) and facilitate robotic guidance of catheter insertion. In addition, alternative catheter patterns may decrease toxicity by avoidance of the critical structures near the penile bulb while still fulfilling the RTOG criteria.

description: This work investigates the effects of the addition of biosurfactant (lecithin) for the reduction of heavy crude-oil viscosity. Response surface methodology was employed to study the effect of three experimental factors: temperature, water to oil ratio (WOR) and emulsifier concentration (EC). All factors were found to have a high significant effect on the viscosity of the heavy crude oil. The interaction between temperature and WOR had more impact compared to that between WOR and EC. Yet the interaction between temperature and EC was not significant. Moreover, lecithin concentration seemed to have more effect on the viscosity reduction at low WOR. A model was developed for the viscosity with respect to the investigated factors and proved its goodness of fit with R2 of 96.03% at 95% confidence level. A good agreement between predicted and experimental values was achieved. The optimum conditions for achieving a targeted viscosity value based on industrial recommendations were determined and experimentally verified.
