description: Η παρούσα διπλωματική εργασία επικεντρώνεται στο φαινόμενο της παραπτωματικότητας σε παιδιά και εφήβους, εξετάζοντας τους παράγοντες εκδήλωσης, τις ψυχοκοινωνικές επιπτώσεις και τις καλές πρακτικές αντιμετώπισης μέσα από το πρίσμα της ψυχιατρικής παιδιών και εφήβων. Η εργασία διερευνά την πολυπλοκότητα της παραπτωματικότητας, αναγνωρίζοντας την ως ένα φαινόμενο που δεν περιορίζεται σε μονοδιάστατες εξηγήσεις αλλά περιλαμβάνει βιολογικούς, ψυχολογικούς, οικογενειακούς και κοινωνικούς παράγοντες. Η εργασία επιχειρηματολογεί υπέρ της ανάγκης για προληπτικές πολιτικές και εκπαιδευτικά προγράμματα που εστιάζουν στην ενίσχυση των κοινωνικών και συναισθηματικών δεξιοτήτων, την υποστήριξη των οικογενειών και την ενσωμάτωση των νέων σε ένα υγιές κοινωνικό περιβάλλον. Επιπλέον, η εργασία επισημαίνει την ανάγκη για ολοκληρωμένες κοινωνικές και θεραπευτικές παρεμβάσεις που να προάγουν την ψυχική υγεία, την κοινωνική ενσωμάτωση και την προσωπική ανάπτυξη των νέων. Η ανάγκη για διατομεακή και διεπιστημονική συνεργασία από την οικογένεια μέχρι τις εκπαιδευτικές και κοινωνικές και παιδοψυχιατρικές υπηρεσίες και η εφαρμογή καλών πρακτικών που να υποστηρίζουν την ευημερία και την ανάπτυξη των νέων αναδεικνύονται ως κεντρικά στοιχεία για την αποτελεσματική αντιμετώπιση της παραπτωματικότητας σε παιδιά και εφήβους.
description: This thesis focuses on the phenomenon of delinquency in children and adolescents, examining the factors of manifestation, the psychosocial impact and the good practices of coping through the prism of child and adolescent psychiatry. The paper explores the complexity of misbehaviour, recognising it as a phenomenon that is not limited to one-dimensional explanations but includes biological, psychological, family and social factors. The paper argues for the need for preventive policies and educational programmes that focus on strengthening social and emotional skills, supporting families and integrating young people into a healthy social environment. In addition, the paper highlights the need for integrated social and therapeutic interventions that promote young people's mental health, social integration and personal development. The need for cross-sectoral and multidisciplinary collaboration from the family to educational, social and child psychiatric services and the implementation of good practices that support young people's well-being and development are highlighted as central elements for effectively addressing juvenile delinquency in children and adolescents.

Analysis of recent CLAS data on $Σ^{\ast }(1385)$ photoproduction off a neutron target

description: Based on recent experimental data obtained by the CLAS Collaboration, the $Σ(1385)$ photoproduction off a neutron target at laboratory photon energies $E_γ$ up to 2.5\,GeV is investigated in an effective Lagrangian approach including $s$-, $u$-, and $t$-channel Born-term contributions. The present calculation does not take into account any explicit $s$-channel baryon-resonance contributions, however, in the spirit of duality, we include $t$-channel exchanges of mesonic Regge trajectories. The onset of the Regge regime is controlled by smoothly interpolating between Feynman-type single-meson exchanges and full-fledged Regge-trajectory exchanges. Gauge invariance broken by the Regge treatment is fully restored by introducing contact-type interaction currents that result from the implementation of \textit{local} gauge invariance in terms of generalized Ward-Takahashi identities. The cross sections for the $γn\to K^+Σ^*(1385)^-$ reaction are calculated and compared with experimental results from the CLAS and LEPS collaborations. Despite its simplicity, the present theoretical approach provides a good description of the main features of the data. However, the parameters fitted to the data show that the gauge-invariance-restoring contact term plays a large role which may point to large contributions from final-state interactions.

description: Excerpts from the report: Farmers Home Administration (FmHA ) is the credit agency for agriculture and rural development in the U.S. Department of Agriculture (USDA). In 1987, the agency marked its 52nd anniversary of providing financial and technical assistance in rural America. This service has been performed under the successive names of Resettlement Administration, Farm Security Administration, and Farmers Home Administration. When it began in 1935, the agency's original function was to make loans and grants to Depression stricken families and help them regain self-sufficiency in making their living on family farms. Throughout more than half-a-century of operation, FmHA has been concerned primarily with credit and counseling services that have supplemented resources of the private sector for building stronger family farms.

title: Treatment of NSCLC and respiratory diseases through innovative particle engineering approaches: lipid nanoparticles and advanced spray drying techniques
Creators: name: Al Khatib, Arwa
Publisher: name: University of Reading
Year: 2024

description: Background: NSCLC is the most common type of lung cancer, making up 85% of all lung 
cancer cases. One of the primary challenges is the difficulty in early detection, leading to 
low survival rates. Respiratory infections can damage cells, impair lung function, and 
hinder lung cells from destroying cancer cells. Such infections complicate 50-70% of 
cancer cases and cause immunosuppression, preventing the immune system from 
effectively combating cancer. Additionally, chronic lung tissue inflammation can progress 
into cancer. Lung cancer is often accompanied by secondary infections and inflammation 
related to the cancer itself.
Aim: To improve the therapeutic effectiveness of treatments for NSCLC and respiratory 
infections, addressing the primary challenge of limited drug targeting, suboptimal 
bioavailability, and systemic toxicity. Our focus was on investigating innovative strategies
through particle engineering in pulmonary drug delivery to provide more tailored solutions 
for effective treatments.
Methods: This thesis investigated the development and evaluation of lipid nanoparticles 
produced using the microemulsion technique, subsequently transformed into powders 
through spray drying. Additionally, it explored the development of spray-dried 
microparticles utilizing the two and three fluid nozzle configurations, loaded with one or 
two repurposed drugs—pimozide, hydroxychloroquine, or rifaximin—to target NSCLC 
and related infections and inflammations. The thesis evaluated their physical stability, 
chemical integrity, functional performance, and in vitro efficacy.
Results & Conclusion: Pimozide-loaded nanostructured lipid carriers (NLCs) 
outperformed solid lipid nanoparticles (SLNs) and liquid lipid carriers (LLCs) with higher 
encapsulation efficiency, potential cytotoxicity against A549 lung cancer cells, and a 
biphasic drug release profile. NLCs with pimozide and hydroxychloroquine showed 
synergistic antiproliferative and anti-inflammatory effects. Microparticles made with the 
three-fluid nozzle method had better recovery percentages, customized release profiles, 
and enhanced activities compared to the two-fluid nozzle method. Microparticles with 
hydroxychloroquine and rifaximin, prepared using the three-fluid nozzle, exhibited superior antiproliferative, anti-inflammatory, and antimicrobial effects against drug-resistant A. baumannii.

Detection of Somatic and Male Specific Coliphages in Fecally Contaminated Shellfish and Harvest Waters
Creators: name: Freeman, Amanda R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Coliphages are rapidly (<12hrs) and easily detectable candidate indicators of human enteric viruses in seawater and shellfish. Furthermore male-specific (F+) RNA coliphages may be useful in differentiating human and animal fecal contamination by classification into one of their four serogroups. Despite their indicator potential, there has been only limited field evaluation of coliphages as indicator viruses of shellfish quality. We studied the concentrations and types of coliphages in six well characterized estuarine field sites impacted by fecal pollution. At each site, there were three stations designated as either open, transitional or closed to shellfish harvesting according to current classification criteria. Samples of water, oysters, and clams were analyzed for concentrations of somatic coliphages , WG49 bacteriophages and male-specific coliphages seasonally for two years. WG49 bacteriophages and F+ coliphages were enumerated on host Salmonella typhimurium WG49 and somatic coliphages were detected on host E. coli C. Coliphages in water were concentrated by adsorption to and elution from membrane filters followed by double agar layer (DAL) plaque assay. Coliphages were extracted from shellfish by homogenizing in nutrient broth, centrifuging, and recovering the supernatant, and the extract was assayed by DAL. WG49 bacteriophages and F+ and somatic coliphages were more prevalent in shellfish than in water by 1 to 3 orders of magnitude. Bacteriophage concentrations in shellfish were higher at sites of known human fecal pollution. Both types of coliphages varied seasonally, with highest levels in winter, lowest levels in summer and intermediate levels in spring and fall. The results of this study indicate that although all three groups of bacteriophages are more prevalent in shellfish than in water, the WG49 bacteriophages and F+ coliphages may be more reliable indicators of fecal contamination. F+ coliphages are easy to detect and quantify and they offer the potential to detect and distinguish between human and animal fecal pollution. For routine monitoring though, total WG49 bacteriophages may be adequate indicators of fecal contamination in shellfish because they are rapidly detected and give information similar to F+ coliphages.

Decentralized network

description: This thesis introduces a decentralized energy trading model implemented on a private blockchain network. It leverages blockchain technology in order to decentralize energy transactions and allow a local network to create its own energy market, controlled by the network participants. It gives the freedom to energy producers and consumers to make their own energy trading deals and define an energy price that is most convenient to both parties without any intermediates. These goals are achieved using a local Ethereum blockchain network, a decentralized application in the form of a smart contract and a web-based user interface where users can interact with the decentralized application and perform energy transactions. The result of this research is a platform called PowerChain. The source code of platform is open source and can be found in the following link: https://github.com/MnAppsNet/PowerChain

Here we demonstrate that the geometric volume (area etc.) of a soliton is singled out in the sense that it exactly coincides with the thermodynamical or continuum-mechanical volume. In addition, this volume may be defined uniquely for rather arbitrary solitons in arbitrary dimensions.

description: We use the Fisher matrix formalism and semi-numerical simulations to derive quantitative predictions of the constraints that power spectrum measurements on next-generation interferometers, such as the Hydrogen Epoch of Reionization Array (HERA) and the Square Kilometre Array (SKA), will place on the characteristics of the X-ray sources that heated the high redshift intergalactic medium. Incorporating observations between $z=5$ and $z=25$, we find that the proposed 331 element HERA and SKA phase 1 will be capable of placing $\lesssim 10\%$ constraints on the spectral properties of these first X-ray sources, even if one is unable to perform measurements within the foreground contaminated "wedge" or the FM band. When accounting for the enhancement in power spectrum amplitude from spin temperature fluctuations, we find that the observable signatures of reionization extend well beyond the peak in the power spectrum usually associated with it. We also find that lower redshift degeneracies between the signatures of heating and reionization physics lead to errors on reionization parameters that are significantly greater than previously predicted. Observations over the heating epoch are able to break these degeneracies and improve our constraints considerably. For these two reasons, 21\,cm observations during the heating epoch significantly enhance our understanding of reionization as well.

description: OCD and BDD are considered distinct, yet closely related and highly comorbid disorders. Despite several overlaps, the associations between specific symptoms remain unclear. Current research suggest that the clinical presentation of OCD and internalising disorders differ in individuals who self-report exposure to trauma. However, it is unknown whether the same is true for BDD and, moreover, whether the relationship between BDD and OCD symptoms is different among individuals who have been exposed to trauma compared to those who have not. Investigating the clinical structure of BDD and OCD symptoms, and the nature of exposed trauma and its associations between these symptoms, may be particularly helpful in future treatments. It may be possible for treatments to target potential key symptoms, that drive psychological distress.

Physiological Community Characterization of a Pure-Oxygen Industrial Activated Sludge System and Investigations into Factors that Affect Process Performance
Creators: name: Hall, Joel Reid
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: The microbial degradation or propylene glycol (PG) and ethylene glycol (EG) was assessed under normal operating conditions and during periods of upset in batch studies with mixed liquor from a pure-oxygen industrial activated sludge, system. The mixed liquor microbial community exhibited rapid PG turnover times on all sample dates, however EG turnover times were consistenly greater than the hydraulic residence time, of the reactor. EG degradation significantly decreased when PG flow to the reactor ceased, suggesting that PG stimulates EG degradation. Contradictory to this, EG degradation by the community and by pure cultures from the system was found to be inhibited in the presence of PG. It appears that PG and EG degradation in the reactor are bi-phasic with PG being degraded preferentially over EG, but PG being required to maintain a viable community. Physiological and kinetic studies revealed that the microbial community of the system is not metabolically diverse. While all cultures isolated from the system were capable of degrading PG, only two were capable of degrading EG. PG and EG degradation appear to be dominated by cultures with similar enzyme kinetics. Failure to isolate cultures capable of utilizing EG as a sole carbon and energy source and the antagonistic effects of PG on EG degradation suggest that the microbial community of the system requires PG as a carbon and energy source and that EG is cometabolized by non-specific constituitive enzymes wlth a greater affinity for PG than EG.

description: We present a two-band Bose-Hubbard model which is shown to be minimal in the necessary coupling terms at resonant tunneling conditions. The dynamics of the many-body problem is studied by sweeping the system across an avoided level crossing. The linear sweep generalizes Landau-Zener transitions from single-particle to many-body realizations. The temporal evolution of single- and two-body observables along the sweeps is investigated in order to characterize the non-equilibrium dynamics in our complex quantum system.

Assessment of the relative reduction factor for an ozone attainment demonstration in Houston, TX
Creators: name: Valencia, Alejandro
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The Houston/Galveston/Brazoria (HGB) area has been designated as a non-attainment area for the 8-hour ozone (O3) National Ambient Air Quality standard (NAAQS) set by the US Environmental Protection Agency(EPA). The Texas Commission of Environmental Quality is currently creating a State Implementation Plan to show future attainment following the EPA's guidance document. The guidance describes how to apply air quality models (AQMs) to generate the predictions later used to evaluate O3 attainment. Predictions from AQMs are used in a "relative" respect, rather than in an "absolute" sense by calculating the relative reduction factor, or RRF. The RRF is a ratio of future year to current year average predicted O3 at a given monitor. The main goal of this study is to understand the implications of the averaging technique for calculating the RRF. To assess variability in RRF, this study quantifies the sensitivity of O3 production to changes in precursor concentrations due to human activity throughout the week and to recurring meteorological phenomena in the rise of the simulated planetary boundary layer. At any given monitor, up to 40% of the days used RRF calculations that included these phenomena. Consequently, modeling days were included where O3 concentrations and RRFs can vary by as much as 35ppb and 007, respectively. This introduces a margin of error that can determine the attainment or lack thereof in the HGB area.

description: This note uses a calibrated model with a “pedagogical production function” (Kaffenberger and Pritchett, 2020) to estimate the potential long-term losses to children’s learning from the temporary shock of school closures related to COVID-19. The model shows that without mitigation, children could lose more than a year’s worth of learning even from a three-month school closure as the short-term losses continue to compound after children return to school. Turning to mitigation strategies, the note examines the long-term effects of two strategies, finding that with some mitigation efforts education systems could come back from the crisis stronger than before.

Η διαδικασία κατασκευής πραγματοποιήθηκε με τη χρήση της τρισδιάστατης εκτύπωσης και συγκεκριμένα με τη μέθοδο εξώθησης ημιστερεού υλικού. Το υλικό εκτύπωσης αποτελούνταν από ένα μίγμα πολυμερών Zein/PVP, το οποίο χρησίμευσε ως φορέας για τη δραστική φαρμακευτική ουσία μικοναζόλη. Η προς εκτύπωση μελάνη βελτιστοποιήθηκε περαιτέρω μέσω ρεολογικών μελετών. Μετά την τρισδιάστατη εκτύπωση, προσδιορίστηκε ο χρόνος καταθρυμματισμού καθώς και το ποσοστό εγκλωβισμού της δραστικής φαρμακευτικής ουσίας, ενώ μελετήθηκε το προφίλ απελευθέρωσης της από τα παρειακά υμένια. Επιπλέον, διεξήχθη λεπτομερής φυσικοχημικός χαρακτηρισμός που περιλάμβανε φασματοσκοπία IR και περίθλασης ακτίνων Χ (FTIR, X-RD) και θερμικές μεθόδους (DSC, TGA) για την αξιολόγηση της στερεής κατάστασης των συστατικών του υμενίου. Παράλληλα μελετήθηκαν οι βλεννοπροσκολλητικές ιδιότητές τους, και πραγματοποιήθηκε μελέτη διαπερατότητας καθώς και ιστολογική αξιολόγηση των παρειακών επιθηλίων. Τα αποτελέσματα έδειξαν ότι τα τρισδιάστατα εκτυπωμένα υμένια με αναλογία πολυμερών Zein40/PVP60 αποτελούν μια πολλά υποσχόμενη εναλλακτική λύση για την τοπική χορήγηση μικοναζόλης στη στοματική κοιλότητα.
description: This study aimed to create 3D-printed buccal films containing antifungal properties suitable for pediatric use. The 3D printing fabrication process involved using semi-solid extrusion. The printing material, a blend of Zein and PVP polymers, served as a carrier for the antifungal drug miconazole. Rheological studies were conducted to optimize the printing ink. After printing, the disintegration time and drug loading were measured, and the drug release profile was analyzed. The physical and chemical properties of the buccal films were thoroughly examined using techniques such as Fourier-transform infrared spectroscopy (FTIR) and X-ray Powder Diffraction (XRD), as well as thermal methods (DSC, TGA), to understand the solid-state characteristics of the film components. Mucoadhesive properties were assessed, and permeability studies were conducted to compare the penetration of miconazole in the buccal tissue between the 3D-printed films and a commercially available oral gel formulation. Additionally, histological evaluation was performed on the tissues treated with both the film and the oral gel. The findings suggested that 3D-printed buccal films with a Zein40/PVP60 polymer ratio show promise as an alternative for delivering miconazole locally in the oral cavity.

description: We give a quantitative analysis of the dynamical properties of fermionic cold atomic gases in normal phase, such as the shear viscosity, heat conductivity, and viscous relaxation times, using the novel microscopic expressions derived by the renormalization group (RG) method, where the Boltzmann equation is faithfully solved to extract the hydrodynamics without recourse to any ansatz. In particular, we examine the quantum statistical effects, temperature dependence, and scattering-length dependence of the transport coefficients and the viscous relaxation times. The numerical calculation shows that the relation $τ_π=η/P$, which is derived in the relaxation-time approximation (RTA) and is used in most of the literature, turns out to be satisfied quite well, while the similar relation for the viscous relaxation time $τ_J$ of the heat conductivity is satisfied only approximately with a considerable error.

Investigating Brass Granular Media for Point-of-Use Water Treatment: Microbial Inactivation, and Copper and Lead Removal
Creators: name: Gilles, John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Brass granular media has the potential to inactivate microbial contaminants and remove metal contaminants from water which would be useful in treating water at the point-of-use. In order to evaluate the feasibility of brass for use in water treatment, experiments were conducted to: (i) characterize the microbial inactivation and copper and lead removal of brass in a batch and column configuration; (ii) determine the influence of the metal ions on the disinfection kinetics. In a batch configuration with mixing, brass was able to inactivate E.coli and MS2 and remove copper and lead from water. The majority of the microbial inactivation from brass was found to be attributed to the presence of brass media itself and not the ions released into solution. In a column configuration, E. coli, MS2 and lead removal were low (0.5 Log10, 0.5 Log10 and 20% respectively); however copper removal was >95%.

description: ALMA Cycle 2 observations of the long wavelength dust emission in 145 star-forming galaxies are used to probe the evolution of star-forming ISM. We also develop the physical basis and empirical calibration (with 72 low-z and z ~ 2 galaxies) for using the dust continuum as a quantitative probe of interstellar medium (ISM) masses. The galaxies with highest star formation rates (SFRs) at = 2.2 and 4.4 have gas masses up to 100 times that of the Milky Way and gas mass fractions reaching 50 to 80%, i.e. gas masses 1 - 4 times their stellar masses. We find a single high-z star formation law: SFR = 35 M_ mol^0.89 x (1+z)_{z=2}^0.95 x (sSFR)_{MS}^0.23 \msun yr^-1 -- an approximately linear dependence on the ISM mass and an increased star formation efficiency per unit gas mass at higher redshift. Galaxies above the Main Sequence (MS) have larger gas masses but are converting their ISM into stars on a timescale only slightly shorter than those on the MS -- thus these 'starbursts' are largely the result of having greatly increased gas masses rather than and increased efficiency for converting gas to stars. At z $> 1$, the entire population of star-forming galaxies has $\sim$ 2 - 5 times shorter gas depletion times than low-z galaxies. These shorter depletion times indicate a different mode of star formation in the early universe -- most likely dynamically driven by compressive, high-dispersion gas motions -- a natural consequence of the high gas accretion rates.
Site and bond percolation thresholds in $K_{n,n}$-based lattices: Vulnerability of quantum annealers to random qubit and coupler failures on chimera topologies

description: We estimate the critical thresholds of bond and site percolation on nonplanar, effectively two-dimensional graphs with chimera like topology. The building blocks of these graphs are complete and symmetric bipartite subgraphs of size $2n$, referred to as $K_{n,n}$ graphs. For the numerical simulations we use an efficient union-find based algorithm and employ a finite-size scaling analysis to obtain the critical properties for both bond and site percolation. We report the respective percolation thresholds for different sizes of the bipartite subgraph and verify that the associated universality class is that of standard two-dimensional percolation. For the canonical chimera graph used in the D-Wave Systems Inc.~quantum annealer ($n = 4$), we discuss device failure in terms of network vulnerability, i.e., we determine the critical fraction of qubits and couplers that can be absent due to random failures prior to losing large-scale connectivity throughout the device.

An Examination of the Effectiveness of Video and Supplemental Materials for Introducing Public Participation Methods to Government Employees in the Environmental and Health Fields
Creators: name: Greenberg, Amanda K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Government employees face the regulatory requirement to involve the public in decision-making; however, effectively engaging the community in environmental decisions has been challenging for many agencies and/or their employees. One such challenge is limited training materials aimed at government employees on the topic of community involvement. In response to a stated need for assistance with public participation efforts on the part of government employees in North Carolina, the Research Translation Core of the UNC-CH Superfund Basic Research Program (SBRP) partnered with the Exchange Project (a group housed in the Department of Health Behavior and Health Education in the UNC-CH Gillings School of Global Public Health) to develop an introduction and training video on the topic of public participation. A case study activity was created by the UNC-CH SBRP-RTC to supplement the video. To examine the impact of the training materials on a variety of characteristics associated with effective public participation, 154 state and local government employees in the environmental and/or health fields were divided into three treatment groups (Video-Only, Activity-Only, and Video-and-Activity). In total, 12 training sessions were held, and participants' responses to nine categories of outcome measures were collected prior to, immediately after, and 30-days following training. Scores were reported for all outcome categories including: 1) frequency of interaction with the public, 2) perceived effectiveness of interactions with the public, 3) perceived quality of interactions with the public, 4) personally-encountered challenges in interacting with the public, 5) individual values held on the topic of public participation, 6) responsibilities of a government employee in interacting with the public , 7) emotions experienced around the topic of public participation, 8) knowledge about public participation, and 9) future plans to implement lessons learned. The results suggest that providing an introductory training on public participation methods to government employees is beneficial and effective.

An Investigation of Residual Nonaqueous Phase Liquid Dissolution in Water Saturated Porous Media
Creators: name: Thyrum, Geoffrey Paul
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: Experiments were performed with a two-dimensional flowcell to analyze the size and shape distributions of nonaqueous phase liquid (NAPL) blobs in water saturated porous media. Photographs were taken of NAPL blobs allowing for the quantification of blob characteristics using image analysis methods. Results demonstrated that the blobs ranged in size and shape. Although the median blob size was relatively small, the fewer large blobs contribute to most of the NAPL residual. It was observed that the shape and number of blobs in a given region changed during the dissolution process. Blobs tended to become less complicated in shape during dissolution. Large irregularly shaped blobs of ten broke in to smaller blobs during the dissolution process. The longest lasting blobs originated from the breakup of initially large blobs. Experiments were performed with the two dimensional flowcell and a column apparatus to observe the shape and length of the dissolution front. The propagation of the dissolution front was recorded through sketches, photographs and with an x-ray attenuation apparatus. In many experiments, the dissolution front did not remain stable and dissolution fingers were observed. The fingering process was found to be a function of the initial length of residual, media packing, flowrate, and media size. Gravity did not seem to effect the development of dissolution fingers. Dissolution fingering was observed in an experiment containing a NAPL mixture. In general, finger lengths and widths increased during the dissolution process. A mathematical analysis demonstrated that maximum finger length theoretically increases with increasing flowrate and finger radius. Maximum finger length was shown to be inversely proportional to transverse dispersivity.
