Multiplexed Electroanalysis of Perfluorooctanesulfonate (PFOS) and Lead
Creators: name: DeMartino, Jenna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Per- and polyfluoroalkyl substances (PFAS) are a harmful class of micropollutants that have been found in North Carolina rivers/drinking water plants as a result of industrial waste. It is crucial that we are able to detect these pollutants at their earliest onset into our waterways, so a cheap, portable sensor is needed. Electrochemistry offers an affordable and deployable method to measure analytes at sub-nanomolar concentrations, but since PFAS species are not electrochemically active, the electrode surface must be modified to detect them. Here, molecularly imprinted polymers (MIPs) are applied to the surface of the electrodes to get around this obstacle. To deploy a sensor into the environment with enhanced statistical analysis, an array of electrodes is desired rather than a single electrode. Typical electrode array architectures include averaging the signal from multiple electrodes, individual electrodes connected to multiple potentiostats, or individual electrodes with a single potentiostat and a multiplexing interface in the middle. The latter architecture is the most useful for this project because the electrodes are individually addressable but only one potentiostat is needed. An affordable, universal multiplexing interface was designed by the Dick Lab to connect to any commercial potentiostat; this multiplexer is accompanied by flexible printed circuit (FPC) chips with 78 individually addressable 0.3 mm diameter gold working electrodes. Here, the FPC electrode arrays are MIP-modified and used with the multiplexer to quantify perfluorooctanesulfonate (PFOS) from 0 to 0.5 nM. Furthermore, it is demonstrated that the FPC chips can be used to detect other harmful pollutants such as lead. These results are important in developing a MIP-based, multi-electrode sensor that can be deployed in North Carolina waterways.

The Effects Of Music On the Testing Effect
Creators: name: Mohammad, Elias

description: Music is a vital component of many people’s lives, whether it be routine listening in the morning while getting ready for the day, driving to work with the speakers on, or listening to music while studying and completing homework for school. As a society, we have made music an integral part of our lives without taking into consideration whether it positively or negatively affects the functioning of our brains, and specifically our memory. This can entail whether students are studying in the most efficient way possible for their exams and classwork. Divided attention has been found to disrupt memory encoding but has much less of an impact on the testing effect – the difference in recall following retrieval as compared to restudy. Since students continuously encounter distractions in their day to day lives, it is vital to assess how these distractions, including music, affect their studying habits and final outcomes. Participants studied random word pairs in phase 1, restudied and retrieved the word pairs in phase 2 under full attention (FA) and divided attention (DA), and took a final exam immediately after to assess and confirm the testing effect as well as the interaction between the two. The results confirm that the testing effect did indeed occur even with the distractor of music used in phase 2; however, music did not interact significantly with the testing effect.

description: We apply the Quasi Monte Carlo (QMC) and recursive numerical integration methods to evaluate the Euclidean, discretized time path-integral for the quantum mechanical anharmonic oscillator and a topological quantum mechanical rotor model. For the anharmonic oscillator both methods outperform standard Markov Chain Monte Carlo methods and show a significantly improved error scaling. For the quantum mechanical rotor we could, however, not find a successful way employing QMC. On the other hand, the recursive numerical integration method works extremely well for this model and shows an at least exponentially fast error scaling.
Giovanni Gioviano Pontano

description: If there is an author in the history of the Italian Quattrocento that truly tried to theorize in his writings the multiple manifestations of “life” by synthesizing and refining the complexity of its themes, this is by all means Giovanni Gioviano Pontano. In true light of the humanistic atmosphere of the time, where between life and art one must have chosen art, Pontano embraced art as the fundamental medium through which he could convey and articulate the object of his doctrinal meditations: life, where everything is connected and disposed harmoniously; life, where the active, moral and jovial participation of all individuals is essential to the establishment of society. Since Pontano was a proliferous writer that left behind an abundant production of poetical and philosophical masterpieces, the main objective of this dissertation is to identify which of his works are best suited to narrate his life in conjunction to his humanistic ideals. Leaving behind traditional methodologies, especially those echoing the influence of the Italian Romanticism, this dissertation emphasizes the importance to evaluate Pontano without relying so much on past literary criticism, because it can easily suggest that he was an ambiguous writer, a lascivious poet, a great teacher of morality and a man of profound religious believes: hence the confusion about his true identity and inspiring muse. From an attentive reading of Pontano’s texts, particularly the Charon, Antonius, Asinus, the Treatises on social virtues and various poems, purposely selected from his vast lyrical collections, it is possible to identify the artistic juxtaposition within the context of the society in which they were written, as well as the humanistic disposition of Pontano, whose attitude was not to embrace a single ideological interest, but to deeply treat and evaluate all fields of human understanding. Aware that individual wisdom was useless, Pontano spent his entire existence in sharing his doctrines with his contemporaneous; so much that among the members of his Academia it was customary to debate in which discipline he best shined. Would have Pontano not fully participated as a protagonist to all of the situations he so vibrantly and actively portrayed through art, the importance of his notions on life would have certainly gone unnoticed.

description: In order to estimate the drought effects on capitula characteristics and self-pollination of globe artichoke (Cynara cardunculus var. scolymus Hayek L.), the randomized complete block design was carried out with three irrigation regimes (20 %, 50 % and 80 % depletion of soil available water) and six replicates. The artichoke is mostly open-pollinated, however, after covering the buds and isolation of flowers to prevent cross pollination, 1.79 % self-pollination was observed and this amount was not affected by different irrigation regimes. In stress conditions (50 % and 80 % water depletion) as well as non-stress condition (20 % water depletion), plants with respectively one and two medium capitula and without small capitula had most relative frequencies in the population and drought stress increased these relative frequencies by reducing the number of medium and small capitula in plants. In addition, Capitula size and dry weight were significantly affected by water stress. Water shortage induced severe decrease in length and dry weight of all capitula including large, medium and small, although capitula width was less affected by water deficit and only slight decline in medium (12.5 %) and small capitula (23.7 %) was observed under severe stress condition.

Subjects: subject: 530 Physik

description: The equations of state (EoS) and other thermodynamic properties of plasmas of the light elements H, He, and Li, are calculated using inverted fugacity expansions. Fugacity expansions are known as an alternative to density expansions but show often an inferior convergence. If, however, the inversion can be solved, the fugacity representations may be very efficient. In particular, the contributions of deeply bound states are included in the fugacity expansion in a very effective way. The mathematical problems on nonlinearity connected with the inversion of fugacities to densities are reduced to solvable algebraic problems. The inversion of fugacities to densities is solved separately for two density regions: (i) In the low density, non-degenerate region we consider ring contributions describing screening effects and ladder contributions describing bound state formation. (ii) In the high density, degenerate region the electrons are described by the Fermi–Dirac distribution. Hartree–Fock contributions and Pauli blocking have to be taken into account. The ions are considered as classical, strongly correlated subsystem eventually forming a Wigner lattice. We solve the inversion problem for each of the regions. Near the crossing point, the separate solutions are connected to each other, either by smooth concatenation at the crossing point or by Padé approximations.

SARS-CoV-2 Testing in North Carolina: An Analysis of the Delta Variant’s Impact on Racial and Geographic Disparities
Creators: name: Chandler, Madeline
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Throughout the COVID-19 pandemic, patterns of SARS-CoV-2 testing have been analyzed to identify disparities among different groups and evaluate gaps in the public health response. In this paper, SARS-CoV-2 testing data from the first nine months of 2021 were analyzed for disparities among racial, ethnic, and geographic populations in North Carolina. Particular attention was paid to the months of July to September 2021, corresponding with the emergence of the Delta variant of the SARS-CoV-2 virus. Individually reported race, ethnicity, and county of residence variables were used to construct tables and time series graphs for the following metrics: number of tests, number of cases, test positivity, testing per capita, and cases per capita. County-level vaccination data were also used in the creation of scatterplots and regression models. In this dataset, during the January-September period, there were 8,916,499 tests conducted on North Carolina residents with 613,402 (6.88%) of those tests being the first positive test result an individual had during that period. In the same timeframe, Latinx populations had the highest testing rates and also the highest case rates per capita with a total of 567.47 cases per 10,000 persons. Comparatively, Non-Latinx (NL) Whites and NL Blacks had 353.93 and 450.43 cases per 10,000 persons, respectively. The Latinx population also had the highest testing positivity rate of the three racial-ethnic groups. An analysis of geographic areas found that urban counties in North Carolina had the highest testing rates, but the lowest case rates when compared to rural and suburban counties. The emergence of the Delta variant exacerbated these geographic disparities with the rural and suburban testing positivity rates at 10.10% and 10.06%, respectively, during the months of July-September. The testing positivity rate in urban counties during that same period was 6.96%. These results suggest that there are disparities in the distribution of testing in North Carolina among racial-ethnically and geographically stratified populations, as well as higher rates of cases in already disadvantaged populations.

description: HD 187547 was the first candidate that led to the suggestion that solar-like oscillations are present in delta Scuti stars. Longer observations, however, show that the modes interpreted as solar-like oscillations have either very long mode lifetimes, longer than 960 days, or are coherent. These results are incompatible with the nature of `pure' stochastic excitation as observed in solar-like stars. Nonetheless, one point is certain: the opacity mechanism alone cannot explain the oscillation spectrum of HD 187547. Here we present new theoretical investigations showing that convection dynamics can intrinsically excite coherent pulsations in the chemically peculiar delta Scuti star HD 187547. More precisely, it is the perturbations of the mean Reynold stresses (turbulent pressure) that drives the pulsations and the excitation takes place predominantly in the hydrogen ionization zone.

description: The Anatomai, a lost work written by Aristotle, must have contained a collection of various drawings and figures of species as well as their organs. In his texts (mainly the Historia animalium), Aristotle is often referring to the drawings after the description of species. Our study applies the method of the comparative view (‘Vergleichendes Sehen’) to provide an access to and reconstruction of Aristotle’s lost illustrations based on his textual descriptions. As an example, we chose the treatment of the European lobster (Homarus gammarus L., 1758) in the Aristotelian corpus as a case study. First, we analyse the etymology of the Greek term astakós referring to the lobster and provide an overview on the putative synonyms. Second, we confront the textual basis of the description with several questions concerning the degree of abstraction, the relation between text and image, and the spatial orientation of the image. Finally, we present a step-by-step reconstruction of Aristotle’s illustrations of the lobster based on the various passages dealing with its anatomy in the text of the Historia animalium. The problems which arise by a confrontation of the textual basis with hypothetical images are discussed at a more general level. We conclude that this kind of a text-based image reconstruction is only possible if the object described by Aristotle is unambiguously identifiable and still visually accessible.

description: We investigated the effct of pump wavelength on the modal instabilities (MI) in high power linearly-polarized Yb-doped fiber amplifiers. We built a novel semi-analytical model to determine the frequency coupling characteristics and power threshold of MI, which indicates promising MI suppression through pumping at an appropriate wavelength. By pumping at 915nm, the threshold can be enhanced by a factor of 2.36 as compared to that pumped at 976nm. Based on a high power linearly-polarized fiber amplifier platform, we studied the influence of pump wavelength experimentally. The threshold has been increased by a factor of 2 at 915nm, which agrees with the theoretical calculation and verified our theoretical model. Furthermore, we show that MI suppression by detuning the pump wavelength is weakened for fiber with large core-to-cladding ratio.

Cultural Confinement: Challenges to South Korean Feminism
Creators: name: Koeval, Holly
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This thesis examines the challenges to gender equality and the resistance thereto in the realms of law, language, and sexuality as well as the link to Confucianism in these systems of inequality. While Confucianism and Neo-Confucianism do not hold as much outright power in modern South Korea, the vestiges of their impacts remain and continue to be an oppositional force to calls for women’s rights through feminism. The three aspects I chose to write about contain clear examples of modern forms of sexism in South Korea, as well as continuities of Confucian thoughts regarding women’s roles and women’s statuses in society at large. Methodologically, I utilize newspapers, journal articles, feminist websites, and existing scholarship to create a cohesive argument about the continuous oppression faced by women. This thesis finds that despite progress towards gender equality, South Korea still falls short in these realms. This inequality needs to be addressed in order to increase the quality of life for Korean women. The South Korean election of the conservative candidate Yoon Suk-yeol demonstrates that misogynistic and sexist beliefs about women continue to be upheld in Korean society at large. The results of this thesis indicate that change is slowly ongoing but still necessary for full gender equality to be reached.

description: Temperature variability and extremes can have profound impacts on populations and ecological communities. Predicting impacts of thermal variability poses a challenge, because it has both direct physiological effects and indirect effects through species interactions. In addition, differences in thermal performance between predators and prey and nonlinear averaging of temperature-dependent performance can result in complex and counterintuitive population dynamics in response to climate change. Yet the combined consequences of these effects remain underexplored. Here, modelling temperature-dependent predator–prey dynamics, we study how changes in temperature variability affect population size, collapse and stable coexistence of both predator and prey, relative to under constant environments or warming alone. We find that the effects of temperature variation on interacting species can lead to a diversity of outcomes, from predator collapse to stable coexistence, depending on interaction strengths and differences in species' thermal performance. Temperature variability also alters predictions about population collapse—in some cases allowing predators to persist for longer than predicted when considering warming alone, and in others accelerating collapse. To inform management responses that are robust to future climates with increasing temperature variability and extremes, we need to incorporate the consequences of temperature variation in complex ecosystems.This article is part of the theme issue ‘Integrative research perspectives on marine conservation’.
Future Cognitive Speech: The Study of Adult Influence on Child’s Speech

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: The action of planning for the future has yet to be fully understood. While many discoveries have been made about the process of planning, there is more to be explored. This paper aimed to support and deny, if necessary, previously stated knowledge concerning future cognitive speech in children while also adding new information to the topic. The study examined future cognition and speech by observing children converse with their parents about the future through various activities. The results of the study support the fact adults do play a role in a child’s development of future speech by increasing the number of utterances they produce when speaking about the future. The data also suggests that children do not demonstrate any large differences between their utterances and quality of speech when discussing events about the near-future versus distant-future. Results are discussed in terms of implications for professionals who work with children so they can better structure their developmental expectations of children’s speech milestones.

description: The MINOS experiment, operating in the NuMI beam since 2005, has provided the most precise measurement of the atmospheric mass splitting $|Δm^2_{32}|$, and the recent combination of the $ν_μ$, $ν_e$, and atmospheric neutrino samples has provided some evidence of non-maximal mixing, and hints about the neutrino mass hierarchy and the $θ_{23}$ octant. Construction of the NOvA experiment, situated off-axis in the upgraded NuMI beam, is almost complete. Over the coming years it will have significant power to probe the questions of the mass hierarchy, $θ_{23}$ octant, and the possibility of $\mathcal{CP}$ violation in the lepton sector. This paper gives an overview of the results from MINOS, and of the sensitivity of the NOvA experiment.

description: In primates, same-sex and immature sexual behaviour is widespread and can include mounting and genital presentation. These patterns can be observed in multiple social contexts and across all ages, and can serve functions such as appeasement, reconciliation, practice and dominance assertion. In this study, we investigated same-sex and immature sexual behaviour in a group of robust capuchins (Sapajus nigritus) living in an Atlantic forest fragment and urban areas. We predicted that in order to practice sex, sexual behaviour in same-sex dyads and/or dyads that included immatures would resemble the adult heterosexual repertoire for solicitation through courtship displays, mounts and post-copulatory display. We also predicted that immature individuals would engage more frequently than adults in sexual interactions, in order to practice sex. We conducted all-occurrence observations of sexual behaviour in the study group (28 individuals: four adult males, one sub-adult male, eight adult females, eight juveniles and seven infants) from September 2016 to August 2017. Sexual interactions that included at least one immature individual in the dyad and/or occurred between individuals of the same sex were infrequent (N = 52, 0.13 interactions/hour), but much more frequent than heterosexual sexual interactions between adults in the group (N = 4, 0.01 interactions/hour). The same-sex and immature sexual repertoire resembled the described heterosexual patterns for the same species from the literature. Individuals displayed solicitation behaviours in “one-way courtship”, usually followed by a two-way courtship and then mounts, but post-copulatory behaviour was never observed. Except for the alpha male, all age-sex classes engaged in sexual interactions in same-sex dyads or in dyads that included immature individuals. We found no difference in frequency of participation across age classes, however, male-male dyads engaged more frequently in sexual interactions and may be practicing sex and courtship behaviours. Mounts are unlikely to be a form of dominance assertion as the alpha male did not participate, subordinate adult males did not engage in mounts with other subordinate adult males, juveniles mounted adult males and vice versa, and there were mount switches (taking turns as mounter and mountee) regardless of the initial mounter’s age. Contrary to the post-conflict context observed in Cebus, most mounts in this study were preceded by play. Combining our study with additional evidence for the genus, same-sex mounts and mounts that include immatures seem to occur most commonly in affiliative contexts within Sapajus. Sexual behaviour functions in Sapajus require additional investigation, especially among adult males and juveniles of both sexes.

description: We report the detection during the ALMA Cycle 0 of SiS rotational lines in high-vibrational states as well as SiO and SiC$_2$ lines in their ground vibrational state, towards IRC+10216. The spatial distribution of these molecules shows compact emission for SiS and a more extended emission for SiO and SiC$_2$, and also proves the existence of an increase in the SiC$_2$ emission at the outer shells of the circumstellar envelope. We analyze the excitation conditions of the vibrationally excited SiS using the population diagram technique and we used a large velocity gradient model to compare with the observations. We found moderate discrepancies between the observations and the models that could be explained if SiS lines detected are optically thick. Additionally, the line profiles of the detected rotational lines in the high energy vibrational states show a decreasing linewidth with increasing energy levels. This may evidence that these lines could be excited only in the inner shells, i.e. the densest and hottest, of the circumstellar envelope of IRC+10216.

The Effect of Maternal Prenatal Stress on Toddler Language Development: Testing Breastfeeding as a Moderator
Creators: name: Sabra, Selma Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Previous studies have found that prenatal stress and breastfeeding are associated with child language development. However, previous studies have tended to examine specific causes of maternal prenatal stress rather than general stress, and it is unclear if breastfeeding may help to mitigate the effects of prenatal stress. I conducted this study to investigate the impact of general prenatal stress on toddler language and whether breastfeeding serves as a moderator for the relationship. I performed secondary analysis of data captured from 97 mother-child dyads enrolled in the Brain and Early Experience (BEE) Study. Indices of maternal prenatal stress were captured through self-report and hair cortisol, duration of breastfeeding was captured via maternal interview, and toddler language was assessed at 18 months through maternal report. Using multiple linear regressions, I found that neither measure of prenatal stress (self-report and hair cortisol) predicted toddler language, and breastfeeding did not serve as a protective moderator in the relationship between self-reported stress and toddler language. Breastfeeding only acted as a moderator in the association between prenatal hair cortisol and child understanding and saying words, where breastfeeding exacerbated the negative effect of prenatal stress on toddler language. I discuss possible explanations and implications for these results. Future studies should further explore these relationships by investigating at-risk populations and developing study designs that allow for the testing of causal effects concerning prenatal stress, breastfeeding, and toddler language.
Prioritizing Sources of Fecal Contamination in a High Priority Estuary

description: Estuarine waters worldwide are facing drastic declines in water quality due to increasing anthropogenic influences. Around 43% of the U.S. population lives near an estuary due to the recreational and economic services they provide such as boating and employment. As human dependence on these services grows, estuarine water quality falls. A major contributor to the water quality decline is fecal pollution which poses a large public health risk. This decline is especially apparent in small coastal towns where the influence of anthropogenic change is more significant. Town Creek in Beaufort, NC is one such estuary experiencing a decline in water quality as the town continues to grow to support the influx of tourists and new homeowners. The most likely potential sources of fecal contamination in Town Creek Estuary are damaged sewer infrastructure, leaking septic systems, and stormwater. This project aimed to pinpoint specific sources of fecal contamination throughout the estuary by monitoring the levels of fecal indicator bacteria (FIB), such as total coliforms, E coli, and Enterococcus, as well as Bacteroides spp., specifically the HF183 gene which is a common human fecal pollution indicator. Results showed that FIB concentrations are positively correlated with the previous 72 hours of precipitation and negatively correlated with salinity. We additionally found the presence of dry weather flow contamination which is indicative of sewage contamination. One likely source of contamination is stormwater drains as there was persistent detection of FIB throughout the study and spikes following rainfall events. Another likely source of fecal contamination is the sewer infrastructure surrounding site 1 as there was persistent detection of all FIB analyzed as well as HF183 which was not detected as consistently at all other sites. With these results, we can help the town of Beaufort prioritize sources of fecal contamination and allocate their funds more effectively and efficiently to ensure public safety.

description: We present new Karl G. Jansky Very Large Array radio continuum images of the nuclei of Arp 220, the nearest ultra-luminous infrared galaxy. These images have both the angular resolution to study detailed morphologies of the two nuclei that power the system and sensitivity to a wide range of spatial scales. At 33 GHz, and with a resolution of 0".081 x 0".063 (29.9 x 23.3 pc), we resolve the emission surrounding both nuclei and conclude that is mostly synchrotron in nature. The spatial distributions of radio emission in both nuclei are well described by exponential profiles. These have deconvolved half-light radii of 51 and 35 pc for the eastern and western nuclei, and they match the number density profile of radio supernovae observed with very long baseline interferometry. This similarity might be due to the fast cooling of cosmic rays electrons caused by the presence of a strong (~ mG) magnetic field in this system. We estimate high luminosity surface densities of $\mathrm{Σ_{IR} \sim 4.2^{+1.6}_{-0.7} \times 10^{13}}$ (east) and $\mathrm{\sim 9.7^{+3.7}_{-2.4} \times 10^{13}~(west)~L_{\odot}~kpc^{-2}}$, and star formation rate surface densities of $\mathrm{Σ_{SFR} \sim 10^{3.7\pm0.1}}$ (east) and $\mathrm{\sim 10^{4.1\pm0.1}~(west)~M_{\odot}~yr^{-1}~kpc^{-2}}$. These values, especially for the western nucleus are, to our knowledge, the highest luminosity and star formation rate surface densities measured for any star-forming system. Despite these high values, the nuclei lie below the dusty Eddington limit in which radiation pressure is balanced only by self-gravity. The small measured sizes also imply that the nuclei of Arp 220 are only transparent in the frequency range ~ 5 to 350 GHz. Our results offer no clear evidence that an active galactic nucleus dominates the emission from either nucleus at 33 GHz.

Biculturalism, Identity, and Wellbeing among Middle Eastern/North African Young Adults

description: 	Due to the demographic categorization of people of Middle Eastern and North African (MENA) descent as White, this population is underrepresented in research. MENA people have lived experiences that are distinct from their European-White counterparts. Our study aims to answer three questions among MENA identifying young adults. (1) how might family demographic factors be related to biculturalism?; (2) how might biculturalism be related to identity?; and (3) how might biculturalism be related to wellbeing? A sample of 29 MENA young adults (M=20.45, SD= 1.859) completed an anonymous online survey. Biculturalism was measured using the Vancouver Index of Acculturation. Participants’ ethnic identity was measured using 2 measures: 1) Ethnic Identity Scale (Umana-Taylor et al., 2004) and 2) an adapted version of the Multidimensional Inventory of Black Identity (Sellers et al., 1997). Wellbeing measures were life satisfaction, anxiety, and depressive symptoms.  Analyses indicated that heritage culture was significantly positively related to ethnic identity exploration, resolution, and private regard. Heritage culture was also negatively related to public regard. However, neither exposure to heritage language nor the parental length of residence in the United States were significantly related to biculturalism. Father-child relationship in adulthood was positively related to public regard. Identity variables were found to be significantly related to wellbeing outcomes. Some limitations of this study include the small sample size and operationalization of biculturalism. Future studies should continue to expand research on biculturalism and explore other measures suited to MENA populations.

description: A colorimetria é essencial na Conservação e Restauração de Bens Culturais, uma vez que são muitas suas aplicações, que segundo (Plutino e Simone, 2020, p. 56) podem auxiliar na mensuração esmaecimento em superfícies e a identificação de produtos que não altere a cor ao serem aplicados em bens culturais. A precisão dos aparelhos de medição colorimétrica é crucial para esse tipo de pesquisa, pois equipamentos menos precisos tendem a fornecer resultados incorretos e distantes da realidade, comprometendo o trabalho do conservador e restaurador. A pesquisa tem como objetivo avaliar a precisão dos equipamentos de colorimetria dos respectivos fabricantes i1Publish Pro 3 (X-Rite), Stil (Stil), ColoriMeter (ColoriMeter), Color Muse (Color Muse) e Color Reader EZ (DataColor). A metodologia consiste em verificar se os valores colorimétricos (em Lab*) gerados por esses aparelhos são próximos aos informados pelo fabricante da cartela SpyderCheckr 24 (Datacolor). A validação dos dados é feita por meio do Delta E (número que indica a diferença entre as cores). Além disso, foi realizada análise dos espectros das cores da cartela para avaliar qual equipamento apresenta resultados mais precisos.Os resultados indicaram que o melhor equipamento foi o i1Publish Pro 3, pois ele apresentou os melhores resultados dentro da metodologia proposta, ou seja, Delta E de 2,65. O pior resultado foi do ColoriMeter, cujo Delta E foi de 9,67.
