O presente artigo procura verificar se a cor será causa de maior frequência de distorção perceptiva no Rorschach, como o sugerem alguns estudos normativos. A aplicação dos cartões II, III, VIII, IX e X, na sua versão original e numa versão cromática, a dois grupos de jovens de ambos os sexos, permitiu verificar, com respeito às variáveis Fo, F−, Fu, XA, tendo em conta as características cromático/acromático e masculino/feminino, o seguinte: quanto à variável Fo, verifica-se uma diferença estatisticamente significativa, favorável ao sexo feminino, no cartão IX; quanto à variável Fu, ocorre uma diferença estatisticamente significativa, favorável à versão cromática no cartão X, que se repete com a variável XA. A análise de variância a dois fatores, cromático/acromático e sexo, revela que o sexo feminino é responsável pelo seu valor mais elevado no cartão IX, tanto em Fo como em XA. O presente estudo não permite estabelecer uma relação de causalidade entre a variável cor e a distorção perceptiva no Rorschach.

Background: pH, subcutaneous fat thickness (SFT), and color are fundamental variables to define the organoleptic characteristics of meat. However, multivariate relationships of those traits remain unexplored in bovine meat. Objective: To investigate the multivariate relationships among pH, subcutaneous fat thickness, and color parameters in bovine meat using canonical correlation analysis. Methods: A dataset containing 173 individual records of pH, SFT, and color parameters (a*: intensity of red color, b*: intensity of yellow color, and L*: lightness) from five Brazilian beef cut types (Breed: Nellore; cuts: acém, contrafilé, fraldinha, patinho and picanha) was constructed. Multivariate relationships between color variables (a*, b*, and L*) and chemical variables (pH and SFT) were explored using the CANCORR procedure of SAS. Results: Two canonical correlations between U (a*, b*, and L*; color variables) and V (pH and SFT; chemical variables) variates were significant (p<0.01). First and second canonical correlations were 0.463 and 0.282, respectively. Canonical weights for variates were for U1: a* = 0.707, b* = 0.406, and L* = -0.039; U2: a* = 0.364, b* = -0.898, and L* = 1.234; V1: pH = -0.376 and SFT = 0.935; V2: pH = 0.927 and STF = 0.356. Conclusion: Subcutaneous fat thickness significantly affected intensity of red and yellow colors, whereas pH significantly affected lightness. The results of this study may be useful for a better understanding of the role of muscle metabolism and its implications on the organoleptic characteristics of bovine meat. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the color stability and the surface roughness of different composites brushed with toothpastes presenting different levels of abrasivity. Thirty discs of each material were obtained using michohybrid composites (Brilliant NG and Charisma Diamond) and a nanocomposite (Filtek Z350XT). The initial color (CIELab) and surface roughness (confocal laser scanning microscopy) of resin discs were evaluated. Afterwards, 10 specimens per group were brushed with the following dentifrices: Maximum Cavity Protection, Sensodyne Repair & Protect and Colgate Sensitive Pro-Relief. Brushing was performed with an electric toothbrush equipped with soft bristle head, with standard power and weight, for 30 minutes. Every 30 seconds, 1.0 ml of the slurry was injected between the bristles of the brush and the specimen. After abrasive challenge, the samples had their color and roughness reevaluated. Data were submitted to the Kruskal-Wallis test (color change) or the t-test (surface roughness). The level of significance was 5%. Results: Brushing did not significantly change the color of the composites tested in the study herein. On the other hand, the surface roughness of the composites was significantly affected by the abrasive challenge, regardless of the toothpaste used. The surface roughness change was similar for all the composites. The abrasive challenge with the toothpastes Maximum Cavity protection, Sensodyne Repair & Protect and Colgate Sensitive Pro-Relief was not able to significantly change the color of the composite resins. Nevertheless, the abrasive challenges significantly altered the surface roughness of all the evaluated composites. However, the changes in surface roughness were statistically similar in the microhybrid and nanofilled composites. [ABSTRACT FROM AUTHOR]

Este estudo, in vitro, teve como meta medir a influência das cores sobre a degradação da força de elásticos ortodônticos em cadeia da marca Morelli®, após estirados e submersos em saliva artificial. Os valores foram obtidos após mensuração imediata (tempo zero), 30 minutos, 1 hora e 24 horas de submersão. Foram analisadas vinte amostras, escolhidas aleatoriamente, de cada uma das cores de elásticos em cadeia sintéticos. Cada amostra, composta por 4 elos, foi inicialmente pré-estiradas, com o auxílio de duas sondas exploradoras, até o estresse. A determinação da quantidade de estiramento dos elásticos para aferição corresponde a 50% do valor do pré-estiramento inicial. Após a leitura inicial, cada um dos elásticos foi retirado do dinamômetro com o auxílio de uma pinça clínica e em seguida assentados sobre um gabarito com pinos desenvolvidos para acomodação dos elásticos. Os conjuntos (gabarito + elásticos) foram imersos em saliva artificial a 37 °C (histerese ± 1°). Nos intervalos de tempo 30 minutos, 1 hora e 24 horas. As amostras no tempo zero apresentavam diferenças significativas (p

Resumo O maracujá-doce (Passiflora alata Curtis) produz frutos comercializados para consumo in natura com aroma agradável, baixa acidez e elevados teores de sólidos solúveis totais. Objetivou-se com este trabalho avaliar aspectos físico-químicos de frutos obtidos dos diferentes genótipos de P. alata. Foram avaliados os frutos de 14 genótipos previamente selecionados. Avaliaram-se o rendimento de polpa com e sem sementes, a composição química, teores de potássio e de sódio, pH, acidez total titulável, teor de sólidos solúveis totais, ratio, teores de compostos fenólicos e de flavonoides e cor. O experimento foi delineado em blocos casualizados (DBC) com quatro repetições. Foi realizada análise de variância e posteriormente teste de Scott-Knott, a 5% de probabilidade. Os genótipos 2, 5, 6, 7, 11, 13 e 14 se destacaram pelos maiores valores de ratio, sendo superiores a 11,0. Por outro lado, os genótipos 2, 3, 5, 7, 8, 9, 11, 12 e 13 apresentaram rendimento de polpa com semente acima de 18,0%. No que se refere aos compostos bioativos, destacaram-se os genótipos 1 e 7, em função dos teores de compostos fenólicos e de flavonoides, respectivamente. Os genótipos, obtidos a partir das seleções, demonstram a alta variabilidade na composição química da polpa e no conjunto de aspectos físicos e químicos do maracujá-doce.

Um clássico dos estudos raciais no Brasil é a obra de Thales de Azevedo, As Elites de Cor – um estudo de ascensão social. O livro, resultado de uma pesquisa realizada na cidade de Salvador, Bahia, no início dos anos cinquenta, analisa a mobilidade vertical de negros, os canais de ascensão social, resgatados através de inquéritos e observações diretas em escolas, universidades, clubes e análise de fotos da Polícia Civil. Nenhum pesquisador que esteja fazendo uma pesquisa séria sobre a temática racial pode deixar de ler esta obra de referência, mesmo discordando de suas conclusões finais. O livro de Thales de Azevedo nos apresenta depoimentos e dados que possibilitam algumas conclusões e inevitáveis comparações com a situação atual dos negros em nosso país.

Resumo A alta procura por alimentos nutritivos e de fácil consumo tem impulsionado o mercado de frutas e hortaliças minimamente processadas (MP). No entanto, estes alimentos têm uma curta vida de prateleira, são marcados pela rápida deterioração. A radiação ultravioleta-C (UV-C) é uma técnica não térmica, limpa e de baixo custo que pode servir como alternativa aos sanitizantes comuns. Porém, a sua baixa penetração em alimentos tem limitado sua aplicação neste ramo da indústria. Objetivou-se revisar o efeito germicida da radiação UV-C em alface e maçã minimamente processados e os possíveis danos às características físicas e sensoriais, além de realizar uma avaliação dos fatores envolvidos nesta técnica. Uma redução de 1 a 2 log UFC/g da microflora natural destes vegetais é facilmente atingida com doses moderadas, para diversos grupos de microrganismos deteriorantes. Uma maior redução nos níveis de patogênicos inoculados, acima de 4 log UFC/g, foi verificada quando doses maiores foram utilizadas. Para a alface MP, a superfície irregular é considerada um limitante, por reduzir o contato entre a radiação e os microrganismos. Essa limitação pode ser superada alterando parâmetros do processo, como distância da fonte emissora e exposição de ambos os lados do vegetal. A cor das folhas foi melhor preservada com emprego de radiação UV-C em doses moderadas. Na maçã MP, alterações indesejáveis, como a intensa perda de massa e o escurecimento pronunciado, estão associadas a um severo dano celular em doses mais elevadas. Tais efeitos puderam ser evitados expondo a fruta por um menor tempo. Em geral, verificou-se boa aceitabilidade de alface e maçã MP tratadas com radiação UV-C. O tipo de fruta ou hortaliça utilizado e a sua topografia exercem grande influência na eficiência da técnica. Não foi possível sugerir uma dosagem adequada para a alface ou a maçã MP, visto que os poucos estudos disponíveis diferem quanto à variedade de alface ou maçã estudada, na forma como os tratamentos foram conduzidos e na dose exposta.

Leaf senescence is a programmed developmental process regulated by various endogenous and exogenous factors. Here we report the characterization of the senescence-regulating role of DEAR4 (AT4G36900) from the DREB1/CBF (dehydration-responsive element binding protein 1/C-repeat binding factor) family in Arabidopsis. The expression of DEAR4 is associated with leaf senescence and can be induced by ABA, JA, darkness, drought and salt stress. Transgenic plants over-expressing DEAR4 showed a dramatically enhanced leaf senescence phenotype under normal and dark conditions while the dear4 knock-down mutant displayed delayed senescence. DEAR4 over-expressing plants showed decreased seed germination rate under ABA and salt stress conditions as well as decreased drought tolerance, indicating that DEAR4 was involved in both senescence and stress response processes. Furthermore, we found that DEAR4 protein displayed transcriptional repressor activities in yeast cells. DEAR4 could directly repress the expression of a subset of COLD-REGULATED (COR) and RESPONSIVE TO DEHYDRATION (RD) genes which have been shown to be involved in leaf longevity and stress response. Also we found that DERA4 could induce the production of Reactive oxygen species (ROS), the common signal of senescence and stress responses, which gives us the clue that DEAR4 may play an integrative role in senescence and stress response via regulating ROS production.

Resumo A microencapsulação é um processo indicado para proteger substâncias que são susceptíveis à degradação ou redução da sua funcionalidade por causa de diferentes reações, por exemplo, oxidação, hidrólise, entre outras. O objetivo deste estudo foi avaliar o efeito da microencapsulação, usando como materiais de parede maltodextrina ou amido modificado, sobre a estabilidade de hidrolisados proteicos de okara. A pesquisa analisou a microestrutura, a capacidade antioxidante e a cor das amostras durante a estocagem dos pós por 120 dias a 35 °C. As micrografias obtidas por microscopia eletrônica de varredura indicaram que o processo de microencapsulação favoreceu a integridade física das partículas. A diferença de cor observada entre as amostras encapsuladas e não encapsuladas foi proveniente, provavelmente, da adição de materiais de paredes que contribuíram para a mudança da cor do pó obtido por spray drying. Os resultados indicaram que as microcápsulas obtidas por spray drying usando maltodextrina ou amido modificado mantiveram a cor dos pós e apresentaram boa habilidade em sequestrar o radical livre ABTS e teor de substâncias redutoras do reagente Folin-Ciocalteu durante a estocagem.

Higher plants suffer from mild heat stress when temperatures increase by 5 °C above optimum growth temperatures. This produces changes at the cellular and metabolic levels, allowing plants to adapt to heat conditions. This study investigated an increase of 5 °C above the optimum growth temperature (26 °C) of tomato plants in the tomato—Pseudomonas syringae pv. tomato pathosystem. A temperature increase above 26 °C affects plant development, the defensive pathways activated against Pseudomonas syringae pv. tomato strain DC3000 (PstDC3000), and the bacterial growth and virulence machinery. The results demonstrated that tomato plants were able to acclimate to mild heat stress, showing no symptoms of damage. Moreover, plants subjected to a 5 °C increase (T31 °C plants) showed higher basal levels of metabolites such as proline and putrescine, which probably act as compatible osmolytes. This demonstrates their importance as key components of thermotolerance. When grown under mild heat stress, plants were less susceptible to PstDC3000 and showed increased accumulation of abscisic acid, jasmonic acid-isoleucine, and spermine. In addition, the temperature increase negatively affected the infectivity of PstDC3000. Inhibition of the genes responsible for quorum sensing establishment and synthesis of flagellin and coronatine was observed in bacteria extracted from T31 °C plants. Analysis of the genes involved in the synthesis of the type III secretion system indicates the important role of this system in bacterial growth under these conditions. As the known resistance mechanisms involved in the defense against PstDC3000 were not activated, the changes in its virulence mechanisms under high temperatures may explain the lower infection observed in the T31 °C plants.

O texto parte da premissa de que o design contemporâneo trabalha numa linha de pensamento que coloca o homem no centro do projeto. Essa concepção vem do livro Uomo al centro del progetto e de um artigo de Flaviano Celaschi intitulado “O corpo como matéria-prima do projeto”. Feita essa introdução, o texto define a noção de corpo como um campo de linguagem. Na sequência, aborda o tema da cor do corpo humano e também da cor aplicada ao corpo. Finalmente, propõe a análise de três projetos cujos temas têm a ver com essa relação do corpo com as cores, no campo da fotografia. A intenção é mostrar como cada um dos casos analisados, sob o ponto de vista do design, embora com percursos metodológicos, linguagens e resultados bastante distintos uns dos outros, trabalha a ideia do “corpo como matéria-prima do projeto”.

A partir de uma análise da relação entre o texto verbal e o visual no livro Pequeno Azul e Pequeno Amarelo de Leo Lionni (2011), este artigo tem como objetivo estabelecer um estudo intermidiático da obra, buscando compreender, principalmente, o papel da cor neste espaço narrativo, conferindo-lhe relevância em relação à história e desdobrando as suas potencialidades de sentido. Para isso, será considerada a função da cor como personagem, incorporando suas especificidades na criação de um texto mixmídia, cujos signos possuem coerência no momento em que são lidos juntos, sem que haja subordinação entre palavra e imagem-cor.

La poésie des troubadours nous paraît souvent désincarnée. Le corps y cède la place soit au cœur soit à une personnification de l’amour qui nous paraît abstraite. Mais le cœur peut être de chair. Et l’amour, de genre féminin même au singulier dans l’ancienne langue, est souvent une désignation discrète de la femme aimée, qui lui est substituée comme référent du pronom personnel la. Réticences et prétéritions voilent moins le corps qu’ils n’excitent le désir dans une imagination fiévreuse de la nudité. Décrit avec gaillardise ou dissimulé avec effroi, le corps féminin, le corps aimé est gênant. Les troubadours ont parfois su dire cette gêne en ne la disant pas. L’audace de leur poésie est dans la timidité. « La plus belle qui jamais naquit nue », écrit Guilhem Adémar. Comment serait-elle née autrement que nue ? Mais comment l’imaginer nue autrement qu’à sa naissance ?

The effect of maturation on the physical (pH, color, weight loss on cooking, and shear force) and biological (microbiology, concerning mesophiles and psychrotrophiles, and sarcomere length) characteristics of the Longissimus thoracic lumborum muscle of adult Nellore cattle was assessed over four maturation periods (0, 7, 14, and 21 days) and two cut thicknesses (2.5 and 7.5 cm). Sixty-four Longissimus thoracic lumborum muscles from castrated Nellore males were purchased from Frigorífico Nutrial, Sergipe, Brazil. The study was performed using a completely randomized design, corresponding to a 2 x 4 factorial with eight replicates. The microbiological analysis revealed the sanitary conditions in which the samples were handled and stored, yielding counts of psychrotrophiles (2.18 x 105 CFU g-1) and mesophiles (2.4 x 105 CFU g-1) well below the critical deterioration level (106 CFU g-1). The pH (5.57) and the loss on cooking (24.13%) were not influenced by the evaluated variables (P > 0.05). The other evaluated parameters significantly varied as a function of the maturation period and the cut thickness (both P < 0.05). Meat luminosity varied with both the cut thickness and maturation period. The 2.5-cm-thick cut matured for 14 days and the 7.5-cm-thick cut matured for 21 days were darker than the 2.5-cm-thick cut matured for 7 days and the 7.5-cm-thick cut matured for 14 days, which were the lighter-colored samples (similar to non-matured meat). The intensity of the red color of the meat was different beginning after 14 days of maturation in the 7.5-cm cuts (P < 0.05) but differences were not evident in any of the 2.5-cm cuts (P > 0.05). Regarding the b* intensity, the 2.5-cm cut yielded a darker staining at time zero, which decreased with the maturation period. However, the 7.5-cm cut differed between the non-matured and the matured samples. Regarding the red and yellow color of the meat fat (a* and b*, respectively), a* displayed lighter intensity at 7 days of maturation or the 2.5-cm cut (P < 0.05), while the intensity of b* was similar from 7 days of maturation onwards for both cuts (P > 0.05). The shear force of the meat decreased to 4.49 kgf at 21 days of maturation. The sarcomere length varied for the 2.5-cm cut (P < 0.05) but not for the 7.5-cm cut, which remained constant (P > 0.05). Longissimus thoracic lumborum muscle of adult Nellore cattle should be matured as a larger, vacuum-packed cut for a minimum of 14 days to produce meat with improved quality.

We performed a two-stage experiment: a preference and a validation test in swine litters, to determine whether suckling piglets preferred alternative light colors in their creep area over white light; we also determined whether the preferred color affected piglet behavior. In the first stage, five trials of two consecutive days were performed, each at 21-day intervals. In each trial, 40 piglets, from three to five days old, from four F1 sows (Large White x Landrace), were distributed in four treatments, in a paired scheme, receiving the following treatments: Treatment GR: white light vs. green light ; Treatment BL: white light vs. blue light; Treatment YE: yellow light vs. white light; Treatment RD: white light vs. red light. For the validation test, three consecutive lots of eight F1 sows (Large White x Landrace) and their corresponding maternity were used, remaining from birth under the influence of treatments T_Gr and T_Wh, totaling three replicates. T_Gr corresponded to four creep areaswith green LED light and T_Wh to four nurseries with white LED light. The piglets showed a significant preference only for white over blue. Among the alternative colors, piglets significantly preferred green. In the validation stage, there was no significant effect of colors on the mean percentage of permanence of the piglets inside the creep areas over all evaluated periods. Piglets between two and five days of age prefer green lighting;however, in the creep area, the light color used did not influence piglet behavior. [ABSTRACT FROM AUTHOR]

When performing validation studies on diagnostic classification procedures, one or more biomarkers are typically measured in individuals. Some of these biomarkers may provide better information; moreover, more than one biomarker may be significant and may exhibit dependence between them. This proposal intends to estimate the Area Under the Receiver Operating Characteristic Curve (AUC) for classifying individuals in a screening study. We analyze the dependence between the results of the tests by means of copula-type dependence (using FGM and Gumbel-Barnett copula functions), and studying the respective AUC under this type of dependence. Three different dependence-level values were evaluated for each copula function considered. In most of the reviewed literature, the authors assume a normal model to represent the performance of the biomarkers used for clinical diagnosis. There are situations in which assuming normality is not possible because that model is not suitable for one or both biomarkers. The proposed statistical model does not depend on some distributional assumption for the biomarkers used for diagnosis procedure, and additionally, it is not necessary to observe a strong or moderate linear dependence between them.

The main objective of this study was to analyze and reflect on being black in Brazil in the face of the exhibition “Are we all black now?” which was curated by artist Daniel Lima. The justification for this study arises from the question of the title of the exhibition, which asks about being black and makes people reflect on color/race in Brazil as a challenge in society. The methodological path chosen for this work took place through analysis of the exhibition and information gathering. To carry out this methodological procedure, some sites, photographs exposed in the exhibition and authors’ literature. The conclusive results point out that “Are we all black now?” was extremely relevant, presents an idea of confrontation against institutionalized racism in Brazil. From the point of view of blackness and the deconstruction of the impact of colonization and slavery. [ABSTRACT FROM AUTHOR]

The work–family interface (WFI) in family businesses (FBs) is an underrecognized area of research. The permeable nature of the boundaries in FBs between work and family is often treated as self-evident and as preventing (rather than inviting) research. We review the WFI in FBs based on 72 published articles and highlight implicit assumptions that have given rise to gaps in this literature. We show how boundary theory, the work–home resources model and the resource-based view can be used to highlight issues related to ownership, work–family enrichment, and contextual factors at the individual, family, and firm domains.

The use of color in diagrams in Software Engineering is not new, especially in the Unified Modeling Language (UML), which consists of a set of fifteen diagrams used to document and specify the complexity of a software. However, the application of color is often done in a random way, being in charge of the subjectivity of the designer or the software used to design these diagrams. This paper discusses the use of colors in the UML class diagram according to the model proposed by Coad, Lefebvre and De Luca (1999), who apply color from a professional practice using post-its. The purpose of this article is to perform a descriptive analysis of the application of color to demonstrate the importance of this not only to improve aesthetics, but also as a symbol, facilitating reading, understanding and establishing relationships in the class diagram.

The article analyzes the color or race profile of the contributors and beneficiaries from the Social Welfare in Brazil and the effects of its reform over racial inequality. The Social Welfare contributes to the improvement of the life quality of the Black and Brown population, primarily through cash-transferences to the poorer, the definition of the national minimum wage as reference for the payments of the retirement and pensions, and through the system of differentiated retirement for rural workers. On the other hand, access to the Social Welfare System is affected by the color or race asymmetries in the labor market caused by segregation and discrimination and due to the different shapes of the age pyramid of Whites, Blacks, and Browns, and the likelihood of survival time. The article concludes that the Social Welfare reform not only did not contribute to overcoming the current color and race disadvantages but has a potentiality to deepen it even more.

The objective of this study is to assess the diagnostic accuracy of the personality of the Mexican criminal with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). The inventory was administered to 1,740 Mexican participants of which 870 (728 male and 142 female) are prison inmates, processed and/or sentenced for various crimes from various prisons in Mexico City, and the other 870 participants (728 male and 142 female) are not prison inmates. The ROC (Receiver Operating Characteristic) curve analysis was used to assess the level of diagnostic accuracy through indexes of the Area below the curve (ABC), sensitivity (S) and specificity (E). The analysis was differentiated by gender and showed significant differences

In today’s armed conflicts targeted attacks on humanitarian personnel has become a direct target of organized violence. International humanitarian law, from its outset, has protected health personnel, who are entitled to be respected, providing necessary assistance to carry out its humanitarian mission. In addition, parties to armed conflict must ensure the safety of humanitarian personnel authorized to provide assistance to victims, and this authorization can’t be refused or removed for any arbitrary reasons. It also provides protection to members of peace and humanitarian missions within the United Nations mandate. IHL provides freedom of movement to impartial humanitarian organizations, which is essential to the performance of their duties. Finally, the criminal protection of humanitarian personnel and resources has been included in the Rome Statute of the International Criminal Court and in the Spanish criminal law.Published online: 11 December 2017

The objective of this study is to increase the understanding and transparency of chemical biotransfer modeling into meat and milk and explicitly confront the uncertainties in exposure assessments of chemicals that require such estimates. In cumulative exposure assessments that include food pathways, much of the overall uncertainty is attributable to the estimation of transfer into biota and through food webs. Currently, the most commonly used meat and milk-biotransfer models date back two decades and, in spite of their widespread use in multimedia exposure models few attempts have been made to advance or improve the outdated and highly uncertain Kow regressions used in these models. Furthermore, in the range of Kow where meat and milk become the dominant human exposure pathways, these models often provide unrealistic rates and do not reflect properly the transfer dynamics. To address these issues, we developed a dynamic three-compartment cow model (called CKow), distinguishing lactating and non-lactating cows. For chemicals without available overall removal rates in the cow, a correlation is derived from measured values reported in the literature to predict this parameter from Kow. Results on carry over rates (COR) and biotransfer factors (BTF) demonstrate that a steady-state ratio between animal intake and meat concentrations is almost never reached. For meat, empirical data collected on short term experiments need to be adjusted to provide estimates of average longer term behaviors. The performance of the new model in matching measurements is improved relative to existing models--thus reducing uncertainty. The CKow model is straight forward to apply at steady state for milk and dynamically for realistic exposure durations for meat COR.

Foram estudados os efeitos da suplementação com acetato de alfa-tocoferol (VE) e seleno-levedura (SeL) Sel-Plex, Alltech® Inc, sobre o pH, a capacidade de retenção de água (CRA), perdas por cocção (PC), perdas por gotejamento (PG), cor do músculo e a concentração de selênio no peito de frangos alimentados com dietas a base de milho ou arroz. A partir de 21 dias de idade 200 frangos de corte Cobb foram alojados em 38 boxes (unidade experimental) num delineamento casualizado num arranjo fatorial 2x2x2 em que foram fixados os níveis de suplementação “on top” de VE (0 e 200 mg/kg), SeL (0 e 0,3 ppm) e dois ingredientes da dieta (100% milho e 100% arroz integral) totalizando oito tratamentos: T1) milho + 0SeL + 0VE (controle); T2) milho + 200mg/kg VE + 0SeL; T3) milho + 0VE + 0,3ppm SeL; T4) milho + 200mg/kg VE + 0,3ppm SeL; T5) arroz + 0VE +0SeL; T6) arroz + 200mg/kg VE + 0SeL; T7) arroz + 0VE + 0,3ppm SeL; T8) arroz + 200mg/kg VE + 0,3ppm SeL. A quantidade de selênio no peito foi maior (P < 0,0001) com a inclusão de 200mg/kg de VE, em comparação com os demais tratamentos. Entretanto, observou-se uma interação positiva entre VE e SeL na dieta sobre a quantidade de selênio recuperada na carne (P = 0,06). Foi encontrada melhor CRA com a inclusão de SeL e VE em dietas a base de arroz. A substituição do milho por arroz nas dietas reduziu a cor amarela na carne (P < 0,05). PC e PG não foram significativamente afetadas pelos tratamentos. O pH da carne do peito foi significativamente mais elevado nas aves recebendo dietas suplementadas de SeL. Em conclusão, a interação entre VE e SeL aumenta o selênio na carne, porém, melhorando a CRA somente em dietas a base de arroz. A substituição de milho por arroz integral reduz a intensidade da coloração amarela da carne do peito de frangos.

Com os resultados de alguns estudos normativos do método de Rorschach, verificou-se que os cartões ditos vermelhos, II e III, e dois dos três cartões ditos coloridos, VIII e X, suscitam a frequência mais elevada de respostas com fraca qualidade formal, levantando-se a hipótese de que a cor poderia ser responsável por tal ocorrência. Mediante o uso da versão padronizada e da versão acromática dos cartões II, III, VIII, IX e X, aplicadas a uma amostra de 80 crianças portuguesas de ambos os sexos, com idades entre 11 e 12 anos, constatou-se que apenas no cartão III se encontram indicadores irrecusáveis de que a cor vermelha está associada à frequência mais elevada de respostas de fraca qualidade formal nesse cartão. Adicionalmente, identificou-se que no cartão X a cor contribui para maior frequência de respostas de boa qualidade formal.

The objective of this study was to determine blood lactate concentration during the finishing period and after slaughter and to verify its influence on body weight and meat quality traits of Nellore bulls feedlot finished. Ninety Nellore males were used, with a mean initial body weight of 390 ± 37 kg and age of 24 months. Lactate concentration in the blood was measured by spectrophotometry on days 1 (Lac01), 14 (Lac14), 27 (Lac27) and 69 (Lac69) of the feedlot period and immediately after slaughter (Lac96). Fresh meat samples were collected from the Longissimus thoracis muscle for determination of luminosity (L *), red (a *) and yellow (b *) intensity, shear force and pH of unaged meat and aged for seven days. Lactate concentrations were analyzed by the PROC MIXED of the SAS program, considering in the model the effects of pen and day of blood samples collection. Simple correlations between the studied variables were estimated using the procedure CORR of the program SAS. The lactate was stable during the confinement period, with mean values equal to 4.83 ± 0.30 mMol/L; 5.68 ± 0.29 mMol/L; 5.03 ± 0.29 mMol/L and 4.15 ± 0.31 mMol/L for Lac01, Lac14, Lac21 and Lac69, respectively. The highest mean lactate concentration was obtained on the day of slaughter (Lac96: 10.77 ± 0.27 mMol/L). Significant association was detected between a * and b * color parameters of the unaged meat and the lactate concentration at the day of slaughter (Lac96). There is no association between blood lactate concentration at the day of slaughter and body weight of Nellore animals feedlot finished. Blood lactate concentration on the day of slaughter is associated with the coloring of the meat and is independent of other measures of meat quality in Nellore animals feedlot finished.

O clareamento dental, atualmente, é considerado o tratamento mais conservador em Odontologia Estética, sendo, com frequência, realizado por profissionais de diversas áreas. Diferentes métodos são utilizados para analisar a cor dos dentes dos pacientes submetidos ao clareamento, e, um deles é a análise objetiva espectrofotométrica. Esse trabalho tem como objetivo apresentar dois relatos de casos de clareamento dental de consultório em que a cor foi analisada de maneira subjetiva (Escala VITA®) e objetiva (espectrofotômetro EasyShade®). Dois pacientes que apresentavam a cor dos seus dentes como fator de insatisfação para o sorriso foram selecionados. Nenhum deles apresentava patologias dentárias. Após exame clínico detalhado e profilaxia dentária, foi confeccionada para cada paciente uma matriz de silicone que continha orifícios de diâmetro compatíveis com o do espectrofotômetro e, assim, permitia a padronização da medição objetiva da cor. Ambos os pacientes receberam o clareamento dental com peróxido de hidrogênio de alta concentração (Caso 1 - Opalescence Boost® 40%- Ultradent Products Ind.; Caso 2 Whiteness HP Maxx® 35% FGM Produtos Odontológicos). As medições de cor foram realizadas nos tempos inicial, imediatamente após a primeira aplicação do gel, após 7 dias da primeira aplicação e ao final do tratamento. Em ambos casos houve percepção subjetiva pelos observadores da efetividade do procedimento congruente com a variação observada nos valores obtidos pelo espectrofotômetro. O clareamento de consultório é uma técnica sacramentada pela literatura. Diferentes formas de aferição quanto à sua efetividade podem ser utilizadas com concordância satisfatória.
