Abiotic stressors are the main factors limiting the expansion of territories occupied by grape plantations. Industrial viticulture is concentrated in the south of Russia and is limited by climatic factors that do not allow large-scale production in other regions of the country.The present review considers the molecular mechanisms of resistance to low-temperature stress and discusses the role of the main genes determining the ability of plants to survive and acclimatize during a critical temperature drop.One of the most studied ways of responding to cold stress is the interaction of genes in the ICE-CBF-COR cascade, however, a more accurate understanding of the genes responsible for resistance to abiotic environments specifically in grapes requires additional studies. A series of studies of functions of transcription factors and related genes of response to low-temperature stress in various species (Arabidopsis, tea, orange, blueberry, and grape) have identified four main regulons: 1) CBF/DREB, 2) NAC/ZF-HD, 3) AREB/ABF, and 4) MYC/MYB. Studies have demonstrated the function of the HOS1 gene, which negatively regulates the work of ICE1 (a key resistance factor). The review considers candidate genes in various species of annual plants: ICE1, HOS1, SIZ1, MPK3, MPK6, in families of genes: CBF, COR, RD 29A, LTI78, ERD, LEA; DREB1, ADREB1B; WRKY10, and in perennial crops: ICE1, CBF1, HSP70, SUS1, GST, DHN1, BMY5, BHLH102, GR-RBP3, ICE1, GOLS1, GOLS3; CBF; COR27, RD29B, NCED1, ERF105, ZAT10, SAP15, WRKY3, and LEA.Until recently, interspecific hybridization was the leading method for obtaining cold-resistant grape varieties. The main donor of resistance is V. аmurensis Rupr. Recently, the research focused on the genetic basis of grape resistance to low temperatures is actively developing. For instance, a comparative analysis of the transcriptomes of two species contrasting in this trait, i.e. V. amurensis, resistant to low temperatures, and V. vinifera L. with low cold resistance, made it possible to identify three additional candidate genes with an increased expression in response to exposure to low temperatures, namely CBF3, ERF105 and ZAT10. At the same time, the practical application of modern accelerated breeding methods requires the identification of all additional key genes responsible for resistance to low-temperature stress. The components from the cascade of sequentially expressing ICE–CBF–COR genes (ICE1, ICE2, CBF1, CBF2, CBF3, and HOS1) have been selected as candidate genes.

Winter plants acclimate to frost mainly during the autumn months, through the process of cold acclimation. Global climate change is causing changes in weather patterns such as the occurrence of warmer periods during late autumn or in winter. An increase in temperature after cold acclimation can decrease frost tolerance, which is particularly dangerous for winter crops. The aim of this study was to investigate the role of brassinosteroids (BRs) and BR analogues as protective agents against the negative results of deacclimation. Plants were cold-acclimated (3 weeks, 4 °C) and deacclimated (1 week, 16/9 °C d/n). Deacclimation generally reversed the cold-induced changes in the level of the putative brassinosteroid receptor protein (BRI1), the expression of BR-induced COR, and the expression of SERK1, which is involved in BR signal transduction. The deacclimation-induced decrease in frost tolerance in oilseed rape could to some extent be limited by applying steroid regulators. The deacclimation in plants could be detected using non-invasive measurements such as leaf reflectance, chlorophyll a fluorescence, and gas exchange monitoring. [ABSTRACT FROM AUTHOR]

The study will contribute to the knowledge hiding literature by providing interesting insights in trickledown effect of supervisor knowledge hiding on subordinate knowledge sharing behavior with the co-workers, while; here, LMX as mediator would extend literature of knowledge hiding. Drawing on SET & COR theory by using cross-sectional data collected over structured questionnaire from employees of TEVTA organization, the research will be a considerable addition in both knowledge hiding and knowledge sharing literature. It would also provide the considerable knowledge in OB studies where personality traits i.e., agreeableness as moderator will influence upon relationship of LMX and knowledge sharing by subordinate with coworkers. It argues that, the effects of supervisor knowledge hiding (predictor) not stop at subordinate end while it transmits (trickledown) in coworker and badly affect their social well-being (outcome). More interestingly, agreeableness will moderate relation of LMX & subordinate knowledge sharing behavior with co-workers while the COR will support to author's stance. In addition, theoretical and practical implications of the study are also a key point of the present research. [ABSTRACT FROM AUTHOR]

The use of fossil fuel and wood for cooking poses health, environmental, and economic challenges, especially with the growing population. This has led to an increase in the trend towards the use of clean and sustainable cooking sources, including solar cookers. This experimental study aims to contribute by enhancing the performance of a solar box cooker (SBC) according to the concept of porous media via adding steel fibers inside the box as a modified SBC and comparing it with a conventional SBC. The stagnation test to determine the first figure of merit and the load test to determine the second figure of merit, standard boiling time, and cooker optothermal ratio were conducted under the outdoor conditions of Baghdad city. Also, an energy and exergy efficiency analysis, and calculating the rate of heat loss by three water loads heating and cooling tests. The results revealed that the modified SBC has a higher thermal performance than the conventional SBC. [ABSTRACT FROM AUTHOR]

A criação de montagens experimentais no âmbito didático, a partir de elementos de baixo custo, reaproveitados e reciclados, é uma realidade deste tempo. O destaque que atividades na abordagem da cultura maker têm tido, evidenciam o potencial de propostas e estímulos no âmbito educacional nesta linha. Este trabalho propõe a construção de um protótipo de um colorímetro de baixo custo, utilizando o sensor de luminosidade de um smartphone. O trabalho descreve a montagem do protótipo, os procedimentos realizados para os testes do equipamento e apresenta os dados obtidos através dos ensaios experimentais. Para os testes foram utilizados materiais de limpeza usuais, obtidos no âmbito doméstico. A partir dos resultados obtidos foi possível observar a diferença da absorção entre as amostras utilizadas em decorrência da cor de cada uma delas, como esperado na teoria. O material de limpeza com perfil de absorção mais bem definido foi adotado para uma diluição em água e o resultado da absorbância relativa versus concentração apresentou coerência com fator de correlação acima de 0,93. O protótipo apresentou excelente repetibilidade nas medições e isso, associado ao seu fácil manuseio, indicam que sua utilização pode ser viável em uma sala de aula típica.

This study details the distribution of solid-colored alpacas in relation to their breed, gender, and age in the community of San Miguel de Mestizas, Apurímac. A total of 244 Suri genotype and 2,256 Huacaya alpacas were evaluated. Fleece color determination was carried out through observation and recorded on a registration form. A significant disparity in the proportion of solid-colored alpacas was found between Suri (10.8%) and Huacaya (89.2%) breeds, even after expanding the analysis to include all alpacas. The low prevalence of Suri was attributed to its increased vulnerability in Andean environments, reflected in higher mortality rates and lower reproduction. The study highlighted a predominance of female alpacas (69.6%), indicating management practices focused on males, impacting birth rates and offspring survival. Agespecific analysis revealed challenges in reproduction, with a limited proportion of alpacas in the milk teeth stage. In Huacaya, a preference for white fleece (66.8%) was evident, indicating a growing demand for colored fleeces. Suri alpacas showed a high proportion of females (71.2%) and a preference for solid colors, but the decline in solid-colored Suri raises concerns about genetic diversity. This detailed analysis emphasizes challenges in population management, color preferences, and the need to preserve genetic variability in the face of the growing demand for colored fleeces in San Miguel de Mestizas.

Este estudo detalha a distribuição de alpacas de cor sólida em relação à sua raça, sexo e idade na comunidade de San Miguel de Mestizas, Apurímac. Foram avaliadas um total de 244 alpacas do genótipo Suri e 2.256 alpacas Huacaya. A determinação da cor do vellón foi realizada por observação e registrada em uma ficha de registro. Foi encontrada uma disparidade significativa na proporção de alpacas de cor sólida entre as raças Suri (10.8%) e Huacaya (89.2%), mesmo após expandir a análise para todas as alpacas. A baixa prevalência de Suri foi atribuída à sua maior vulnerabilidade em ambientes andinos, refletida em taxas de mortalidade elevadas e menor reprodução. O estudo destacou uma predominância de alpacas fêmeas (69.6%), indicando práticas de manejo centradas em machos, afetando a natalidade e a sobrevivência das crias. A análise por idade revelou desafios na reprodução, com uma escassa proporção de alpacas em etapa de dentição de leite. Em Huacaya, a preferência por vellones brancos (66.8%) foi evidente, sinalizando uma crescente demanda de vellones coloridos. As alpacas Suri mostraram uma alta proporção de fêmeas (71.2%) e uma tendência a cores sólidas, mas a diminuição de Suri de cores sólidas levanta preocupações sobre a diversidade genética. Este análise detalhada destaca desafios na gestão de populações, preferências de cores e a necessidade de preservar a variabilidade genética diante da crescente demanda de vellones coloridos em San Miguel de Mestizas.

Purpose: The respect of native hip offset represents a mainstay for satisfying results in total hip arthroplasty (THA). Historically, a great interest has been focused on restoration of femoral offset, while only in recent years, acetabular offset (AO) has been considered. The purpose of the current study was to compare the "single-use peripheral" reaming technique with the "conventional" one for the maintenance of the native COR of the hip and AO in patients undergoing to primary THA. Methods: Eighty patients affected from primary hip osteoarthritis were prospectively enrolled in the study and were divided in two groups (Group A "single-use peripheral" and Group B "conventional" reaming technique). Pre- and post-operatively, AO, acetabular floor distance (AFd) and acetabular version (AV) were assessed through a CT scan. A comparison between groups for the radiological parameters, surgical time and complications was performed. Results: The demographic data were similar in both groups. The complications rate and the AV did not differ statistically between groups. Group A presented a statistically significant shorter surgical time and lower variation between pre- and post-operative AO and AFd. Statistical significance was defined as p < 0.05. Conclusions: The "single-use peripheral" reaming technique demonstrated to be more reliable in reproducing the native COR and AO of patients undergoing to primary THA than the "conventional" one. The operative time was significantly reduced, and it may lead to a reduction in the infection risk even though it was not observed in the current study. Further research could be useful to validate such findings and to assess clinical impact and long-term survival of the implant. [ABSTRACT FROM AUTHOR]

The article analyzes the perception of color identity and discusses parameters of racial ethnic classification by studying the color variables of public servants of the career of Specialist in Public Policy and Government Management of Minas Gerais. It has quantitative bias when comparing data from self-declaration and heteroclassification, and qualitative, from the analysis of the perception of career servers regarding self-image and racial identity. Data collection occurred at three different moments, allowing the observation of changes between classifications and the identification of the colors that changed the most. It was observed that color identification may vary for the individual himself according to his/her sense of belonging, influenced by aspects other than the biological. [ABSTRACT FROM AUTHOR]

A maior parte da apreciação de um produto se dá por meio das cores e, se estas forem mal utilizadas, podem levar ao insucesso. O objetivo do presente estudo foi verificar se a cor do recipiente influencia na percepção do esforço a ser exercido para abrir embalagens de água mineral com tampa de rosca. Para isso, foram utilizadas três embalagens com formatos idênticos, porém em três cores diferentes: vermelha, azul e transparente. Os sujeitos não podiam tocar nas embalagens, apenas observa-las e em seguida classifica-las em uma Likert (com ideogramas) de três pontos. Os resultados mostram que jovens e adultos consideraram a embalagem de cor azul como aquela que aparentemente requer menos esforço para ser aberta, enquanto que para os idosos aparentemente é necessário menos esforço para abrir a embalagem transparente. Em todos os casos a embalagem vermelha foi relacionada ao maior esforço, havendo diferença significativa quando comparada com as demais embalagens. No entanto, não houve diferença significativa quando as embalagens azul e transparente foram comparadas entre si.

Os microplásticos podem ser gerados por diversas atividades humanas e são encontrados em diferentes reservatórios ambientais, como os sedimentos fluviais. Considerando a rica biodiversidade da Amazônia e a intensa interferência antrópica na região, torna-se fundamental avaliar o estado dos seus recursos hídricos. Desse modo, o presente estudo teve como objetivo analisar a abundância, morfologia e cor dos microplásticos nos sedimentos do Rio Xingu, no Pará. A coleta de dados e análises foram realizadas em fevereiro de 2023. Os microplásticos foram coletados nos sedimentos do rio e extraídos a partir de princípios de densidade e flotação. Assim, foi detectada uma abundância média de 204±60 partículas/kg, com prevalência das fibras (56,86%) e dos fragmentos (25%), seguidos pelos feixes de fibra (10,78%) e esferas (7,35%). A maioria dos microplásticos encontrados era transparente (57,84%). Nossos resultados revelaram que a abundância de microplásticos no Rio Xingu é maior do que em sistemas dulcícolas localizados zonas agrícolas e de conservação, sendo comparável com aqueles inseridos em áreas urbanas e industriais. Desse modo, destaca-se a necessidade de ações políticas, sociais e ambientais para remediar a presença de microplásticos em sistemas fluviais amazônicos.

A intensa seleção genética devido à necessidade econômica de maior ganho de peso em menor tempo de abate tem alterado o comportamento fisiológico dos animais e ocasionando danos ao tecido muscular. O White Striping (WS) em frangos é caracterizado pelo aparecimento de estrias brancas na carne do peito e da coxa paralelas a direção das fibras musculares e pode ser categorizada como normal (NORM), moderada (MOD) ou severa (SEV). As estrias do WS são facilmente identificadas na superfície da carne de frango e podem afetar diretamente a aceitação e intenção de compra dos consumidores. Este estudo teve como objetivo determinar a incidência do WS e caracterizar a carne do peito de frango quanto ao pH, cor, tamanho, composição química, colágeno total (CT) e colágeno solúvel (CS), capacidade de retenção de água (CRA), perda por cocção (PC), força de cisalhamento (FC), capacidade emulsificante (CE) e perfil de ácidos graxos. A incidência do WS (n= 660) foi de 51.67% e 31.36% para MOD e SEV, respectivamente. Os maiores valores de L* foram observados nas carnes classificadas como MOD e SEV. Os valores de espessura cranial foram maiores nas carnes SEV, com 29% mais CT, 26% mais PC, 27% mais lipídeos e FC quando comparado ao grupo NORM. Não foram observadas diferenças significativas para as demais determinações.

O objetivo do estudo foi avaliar as possíveis variações das características físico-químicas e microbiológicas da carne ovina congelada, embalada a vácuo sob exposição de luz fluorescente em diferentes tempos de armazenamento. Dezesseis músculos Longissimus lumborum de cordeiros machos da raça Ile de France foram coletados para as análises de qualidade da carne de pH, cor, força de cisalhamento, perdas de peso por cocção, capacidade de retenção de água, oxidação lipídica, microrganismos mesófilos, psicrotróficos e enterobactérias. As amostras foram identificadas e armazenadas aleatoriamente em freezer horizontal sob a Incidência de luz fluorescente (CL) e sem Incidência de luz (SL) por 30 e 60 dias mais o tratamento controle (dia 0). Houve interação entre os tratamentos para pH e capacidade de retenção de água (p0,05). A qualidade microbiológica da carne não foi afetada pelo fator luminosidade, exceto para enterobactérias (p

Oocyte vitrification is crucial for livestock reproduction, germplasm conservation, and human-assisted reproduction, but the overabundance of lipids is highly detrimental to oocyte development. It is necessary to reduce the lipid droplet content of oocytes before cryopreservation. This study analyzed the impact of β-nicotinamide mononucleotide (NMN), berberine (BER), or cordycepin (COR) on various aspects of bovine oocytes, including lipid droplet content and the expression levels of genes related to lipid synthesis in bovine oocytes, development ability, reactive oxygen species (ROS), apoptosis, and the expression levels of genes associated with endoplasmic reticulum (ER) stress, and mitochondrial function in vitrified bovine oocytes. The results of our study indicated that 1 μM NMN, 2.5 μM BER, and 1 μM COR were effective in reducing the lipid droplet content and suppressing the expression levels of genes involved in lipid synthesis in bovine oocytes. Our findings showed that the vitrified bovine oocytes treated with 1 μM of NMN had a significantly higher survival rate and better development ability compared to the other vitrified groups. Additionally, 1 μM NMN, 2.5 μM BER, and 1 μM COR decreased the levels of ROS and apoptosis, decreased the mRNA expression levels of genes involved in ER stress and mitochondrial fission but increased the mRNA expression levels of genes associated with mitochondrial fusion in the vitrified bovine oocytes. Our study results suggested that 1 μM NMN, 2.5 μM BER, and 1 μM COR effectively decreased the lipid droplet content and enhanced the development ability of vitrified bovine oocytes by lowering ROS levels, reducing ER stress, regulating mitochondrial function, and inhibiting apoptosis. Furthermore, the results showed that 1 μM NMN was more effective than 2.5 μM BER and 1 μM COR. [ABSTRACT FROM AUTHOR]

O presente artigo promove uma análise acerca das emoções frente à percepção cromática do ser humano, tendo como objeto de estudo o automóvel. Para tal fim, além do levantamento bibliográfico, foi feita uma avaliação da percepção emocional do usuário em relação a automóveis por meio da ferramenta Roda das Emoções de Genebra (GEW) coletados dados de 20 pessoas de dois diferentes grupos. Para essa pesquisa, foram utilizadas imagens do automóvel modelo Renegade, da marca Jeep, selecionado a partir de um grupo de foco, editadas e organizadas em diferentes cores. Com base na análise dos resultados, ficou notória a diferença entre as respostas dos estudantes de Design e dos estudantes de outras áreas. Nesse contexto, os discentes do curso de design apresentaram maior variedade na percepção de emoções, em contraposição com os discentes de outros cursos, os quais assinalaram menos opções emocionais dispostas no GEW.

Background The reliability of the recommendations affecting the clinical decisions is being continuously weighed in everyday practice (Gershlick, 2018). The objective of our study was to assess the consistency of the evidence behind the recommendations. Methods We narrowed our focus on the pharmacotherapeutic aspects of the most recent 38 European Society of Cardiology guidelines and analyzed the correlation between the level of evidence (LoE) classified as A, B and C and the class of recommendations (CoR) subdivided into I, IIa, IIb and III. Results Contrary to the majority of recommendations based on a LoE C (43,0%), fewer recommendations were proposed on heavily evidence-supported LoE A (23.8%), which percentage increased with subsequent updates of the guidelines. The most common recommendation was CoR I (44,9%), while the least common recommendation was CoR III (9,2%). While a similar share of A (39,1%) and C (30,1%) LoE shaped the CoR I nearly half (48,8%) of the CoR III were based on LoE C. Conversely, the overwhelming majority of the recommendations within the scope of LoE A were indisputably strong and classified as CoR I (73,7%). Conclusion The pharmacological aspects of the ESC guidelines are predominantly based on LoE C. A greater number of pharmacological recommendations are based on LoE A in comparison to the general ones. Various constraints significantly skew the credibility due to paucity of scientific data. A more nuanced approach is needed, as the guidelines cannot completely substitute the clinical experience and the patient-centered approach in shaping the optimal therapeutic outcome. • The majority of the pharmacological recommendations is based on LoE C • More pharmacological aspects are based on LoE A, contrary to the general ESC ones • The overwhelming majority of LoE A recommendations is classified as CoR I • Evidence gaps in special cohorts could be mistaken for general lack of confirmation [ABSTRACT FROM AUTHOR]

RESUMO Este artigo tem por objetivo analisar um romance de Ariano Suassuna (1927-2014) publicado postumamente: O sedutor do sertão (2020). Apesar de seu aspecto deleitável (o que poderia gerar a impressão de uma escrita facilitada), O sedutor do sertão se mostra uma obra de ampla complexidade compositiva. Fatos históricos da Paraíba, motivos populares, citação de folhetos de cordel e aproveitamento cromático, tudo isso se concentra na elaboração de uma obra rica em detalhes, bem ao estilo de Ariano Suassuna.

O artigo é um relato sobre visita à tela A Boba (1917), de Anita Malfatti. O teor natural da cor amarela e da voz como limiares entre natureza e cultura são tomados como elementos de convergência entre a poética da artista paulista e outras contemporâneas como as de Joseph Beuys e Tunga, procurando também refletir sobre a hipótese de Giorgio Agamben, em seu primeiro livro de ensaios, sobre o surgimento de uma teatralidade em torno da arte contemporânea que tende a um insidioso “restauro da beleza natural”.

Introduction: In recent years, employees' unethical pro-organizational behavior (UPB) has become a social hot issue. This behavior benefits their organization or colleagues while violating core social ethics. Numerous studies have predominately focused on identifying the antecedents and formation mechanisms of UPB. However, only a few studies have focused on the effects and outcomes of UPB. Moreover, guilt triggered by unethical behaviors can motivate individuals to adopt pro-social behaviors, but studies on the effects of UPB on pro-social behavior of actors are rather limited. Therefore, this study explores the underlying relationship between employees' UPB and their own pro-environmental behavior based on the conservation of resources theory. Methods: Through collecting data (N = 319) from a Chinese online survey company in different time intervals, the theoretical model was tested by the application of Amos 27.0 and SPSS 25.0 for analysis of the data. The CFA, descriptive analysis, hierarchical regression were illustrated in the article. Results: This study demonstrated that, through emotions of guilt, employees' UPB is negatively correlated with their own environmental protection act. While this relationship is being examined, moral identity plays this mediating role, which can moderate the indirect relationship between employees' UPB and their environmental behavior through guilt. Discussion: The purpose of the research was to identify the influence mechanisms that contribute to employees' pro-organizational but unethical behavior. With guilt serving as the mediating variable and moral identity serving as the moderating variable, a research model built on the principle of the conservation of resources theory was constructed. This research examines the impact mechanism and boundary conditions of UPB on individual proenvironmental behaviors from the perspective of employees. This paper discusses the theoretical and practical implications of the report's results. [ABSTRACT FROM AUTHOR]

Solar cookers can greatly reduce the overall carbon footprint of the cooking done in India. In the present work a funnel-type solar cooker is designed using cardboard. After making the solar cooker it is then analyzed on the various performance metrics namely the figures of merit, efficiency value and Cooker Opto–thermal Ratio (COR) which are dependent parameters. Paraffin wax which is a phase change material (PCM) is also incorporated in the testing process to evaluate the overall improvement in the thermal efficiency of the solar cooker. The time taken to break is also calculated. The experimental results show that the solar cooker is capable of reaching a temperature of 125 °C. From the results it can also be seen that using paraffin wax also offers significant improvement in the overall thermal efficiency. The results are tested on various parts of India considering the major cities such as Chennai, Trivandrum, Kanpur and Delhi with the ANN model, which is a deep learning model. The advantage of this model is that it can forecast and estimate the temperature of the absorber plate and water from weather forecasting data which is used to calculate F1 and F2 metrics for the performance of the solar cooker. For all the cities, the model's R2 value is greater than 99% and RMSE values are small. [ABSTRACT FROM AUTHOR]

Mutation in leucine-rich repeat (LRR) kinase 2 (LRRK2) is a common cause of Parkinson's disease (PD). Aberrant LRRK2 kinase activity is associated with disease pathogenesis and thus it is an attractive drug target for combating PD. Intense efforts in the past nearly two decades have focused on the development of small-molecule inhibitors of the kinase domain of LRRK2 and have identified potent kinase inhibitors. However, most LRRK2 kinase inhibitors have shown adverse effects; therefore, alternative-mechanism-based strategies are desperately needed. In this review, we discuss the new insights gleaned from recent cryoelectron microscope (cryo-EM) structures of LRRK2 towards understanding the mechanisms of actions of LRRK2 and explore the potential new therapeutic avenues. Mutation in LRRK2 is a common cause of Parkinson's disease. Over the past nearly two decades, detailed structural and biochemical studies of the Roc domain of LRRK2 have revealed a dynamic nucleotide-dependent conformational equilibrium; however, how this reciprocates to other domains remains unclear. The recently determined cryo-EM partial structures of LRRK2 reveal how the domains might interact with one another and enable examining Roc activity in the context of the full-length protein. The available data suggest that the Roc–COR tandem domain may allosterically regulate the kinase activity of LRRK2. [ABSTRACT FROM AUTHOR]

El cadirat de Santa Maria d’Agramunt és un moble que va desaparèixer, parcialment, a partir de 1953. En aquest treball es presenta les darreres troballes dels elements que van sortir de l’església, la fortuna que van tenir i les localitzacions actuals. També s’hi fa una descripció de la topografia i la morfologia del moble abans de ser desmantellat, mitjançant l’anàlisi de l’estructura, la construcció, l’estil i les fonts a través d’un estudi comparatiu amb altres conjunts. D’aquesta manera, s'ha pogut vincular el cadirat de Santa Maria d’Agramunt amb el també desaparegut conjunt de l’església de Sant Joan de les Abadesses.

A maturação de laranjas e tangerinas consiste em modificações fisiológicas, químicas e morfológicas na casca, na polpa e no suco, que são cruciais para determinar as épocas de colheita de cada variedade. O rato, relação entre a acidez e o teor de açúcar do suco, é o principal parâmetro físico-químico que define a época de colheita, mas o aspecto visual, em especial a coloração, também é importante. A colheita no sul do Brasil estende-se de abril a fevereiro para as laranjas e de fevereiro a dezembro para as tangerinas, dependendo da variedade. Identificar os períodos de oferta de cada variedade é primordial para atender as demandas de consumo e obter os melhores retornos financeiros em períodos de baixa competividade com frutos de qualidade.

In the first half of the 20th century, the arrival of color in cinema gives it a new and very relevant power. The psychological and affective signifiers of the most varied colors, if properly applied, can give the cinematographic work an extraordinary narrative involvement that provokes a strong affective and dramatic impact on the spectator. Throughout this work, we intend to reflect on the possibilities that color has brought to the cinema, going beyond aesthetics and assuming a prominent position in the field of narrative.

Relative alignments of mineral exsolutions and their host crystals can be described by crystallographic orientation relationships (COR). Exsolved phases in garnet from high‐grade metamorphic rocks and igneous rocks may have COR, but the complexity of COR distributions has thus far restricted their use to identifying exsolved phases. Classification of COR also remains mineral‐specific, leaving doubt as to what information COR preserve. To test how COR may be standardized, we calculated mismatch of low‐index crystallographic planes (d‐value ratios) and crystallographic directions (rows of atoms) between precipitates and garnet and defined search criteria for structural alignments likely to be energetically favourable. We analysed published electron backscatter diffraction (EBSD) data for apatite, rutile, ilmenite, corundum, and quartz precipitates in garnet (ntot = 1,296) for the presence of these alignments. Our method predicts between 88% and 98% of observed alignments across the studied minerals and requires only calculations using unit cell parameters. We further show that each exsolved mineral forms COR predicted by the edge‐to‐edge matching model which was developed to describe unambiguous exsolution textures in alloys. Edge‐to‐edge matching aligns atoms at the host–precipitate interface by parallelism or near‐parallelism of crystallographic planes of similar spacing and parallelism of crystallographic directions (rows of atoms) of similar length on the edges of those planes. Edge‐to‐edge matches likely facilitate coherent to semi‐coherent interfaces by lowering surface free energy and strain energy, stabilizing precipitates. These matches are defined by criteria applicable to all minerals, making them an ideal tool for classifying, discovering and interpreting COR of diverse precipitates in garnet. This approach may also predict COR in other geological mineral pairs (e.g., exsolved feldspars). We find that edge‐to‐edge matching may explain the stability of the needle‐shaped morphologies commonly observed for exsolution textures in garnet. Edge‐to‐edge matching COR distributions can be tested as proxies of the state of the host rock at the time of exsolution to evaluate factors such as temperature, cooling rate, degree of undercooling, and/or strain. Patterns of edge‐to‐edge matching COR may be paired with geothermobarometry and/or petrochronology to provide a powerful new tool for studying the histories of granulite and eclogite facies metamorphic and igneous rocks.

Objective: To evaluate the color pigmentation of two commercial brands of esthetic chain elastics immersed in artificial saliva and in the presence of other solutions. Materials and methods: A sample of 100 elastic segments with 6 links of the brands Morelli and Orthometric, divided into five groups of 10 segments each, was immersed in 5 solutions: artificial saliva, red wine, coffee, Coca-Cola, and açai. Pigmentation was evaluated in periods of 1, 3, 7, 14, 21, and 28 days. Intra- and inter-group color changes were performed using photographs taken on a white background with Adobe software. ANOVA and Tukey’s test were used for statistical analysis with a 5% significance level. Results: the elastics submerged in artificial saliva showed no pigmentation in both brands; those exposed to red wine solution showed high pigmentation in relation to those submerged in the other substances; the coffee solution showed pigmentation in the first days, with small pigmentations throughout the 28 days; while those exposed to Coca-Cola and açai solutions showed color changes as of the second week. Conclusion: the diet of patients influences the pigmentation of elastics, which justifies the guidance to patients to avoid foods with high pigmentation potential. [ABSTRACT FROM AUTHOR]

Resumen O objetivo deste trabalho é analisar, a partir dos dados da PNAD de 2014, a mobilidade socio-ocupacional inter e intrageracional na sociedade brasileira e a influência da migração e da cor dos indivíduos no processo de mobilidade social. É proposta uma nova metodologia de estratificação para a construção de estratos socio-ocupacionais, utilizando características como educação, renda e ocupação dos indivíduos. Ainda que marcada por deslocamentos de curta distância entre os estratos socio-ocupacionais, a mobilidade social observada nos dados coletados em 2014 é marcada por chances de mobilidade ascendente, o que denota certa dinamicidade na sociedade brasileira. A análise revela um esvaziamento dos estratos baixos em favor dos estratos médios quando se compara a distribuição socio-ocupacional dos ocupados em 2014 com a geração dos pais. Há uma predominância na mobilidade circular, indicando que os movimentos realizados na estrutura socio-ocupacional se deram mais pela substituição e trocas em postos de trabalho já existentes do que pela transformação da estrutura ocupacional. Foram encontradas evidências de que indivíduos migrantes apresentam mobilidade superior aos não migrantes. Todavia, indivíduos pretos e pardos encontram condições desiguais de mobilidade socio-ocupacional quando comparados aos brancos, e essa desigualdade é atenuada quando se consideram os indivíduos migrantes.

O clareamento dos dentes pode ser realizado de várias maneiras, em consultório, no âmbito caseiro ou com a utilização de produtos OTC (Over-the-Counter). Dentre esses produtos, existem os dentifrícios clareadores que prometem clarear e prevenir o manchamento dentário. Objetivos: (1) investigar o potencial clareador e abrasivo de diferentes dentifrícios no esmalte; e (2) avaliar o efeito do dentifrício Oral-B 3D White Perfection® (Oral-B) na prevenção do escurecimento. Materiais e Métodos: amostras de esmalte bovino foram pigmentadas e escovadas por 14 dias com água (controle negativo) ou com diferentes produtos: Colgate Total 12® (controle), Oral-B, Sensodyne Branqueador Extra Fresh® (Sensodyne) ou Colgate Luminous White Advanced® (Colgate). Oral-B foi testado antes e após pigmentação. As amostras foram avaliadas quanto à cor (espectrofotômetro) e rugosidade superficial (rugosímetro). Para cálculo de alteração de cor (ΔDE00) se utilizou o sistema CIEDE2000. Os dados foram analisados com os testes Kruskal-Wallis, SNK e Mann-Whitney (ɑ=5%). Resultados: O controle negativo apresentou a menor ΔE00 (p

Resultante de seminários realizados pelo Grupo de Pesquisas Cromáticas do Departamento de Artes Plásticas da USP, desde 2009, o livro Reflexões sobre a cor foi publicado em 2021. É formado por ensaios de diferentes autores que problematizam o fenômeno cromático articulando diferentes áreas do conhecimento, passando por abordagens dos aspectos físicos, químicos e fisiológicos da experiência com a cor, da arte moderna à contemporânea. Singular ao reunir pesquisas que destacam questões cromáticas, a publicação é uma incomum e instigante estruturação de estudos que privilegiam a cor.

Os obstáculos epistemológicos propostos por Gaston Bachelard podem ser entendidos como barreiras ao conhecimento. Nesse viés, objetivamos nesta pesquisa analisar obstáculos do conhecimento unitário e pragmático no ensino sobre questões de gênero e Ciência-Tecnologia (CT) presentes em imagens de livros didáticos (LD) de Física do Ensino Médio. Para isso, tivemos como corpus de análise as doze coleções aprovadas pelo Programa Nacional do Livro e do Material Didático de 2018, utilizando como metodologia de análise a Análise Textual Discursiva. Emergiam dessa investigação duas categorias, postas a seguir: 1) A Ciência-Tecnologia apresentada como masculina, de cor branca e produzida em séculos passados e 2) Mulheres enfrentando obstáculos quanto à visibilidade como personagens da CT. O tema gênero e CT pode remeter a um obstáculo do conhecimento unitário e pragmático ao generalizar o gênero masculino e a pessoa de cor branca como sujeitos que fazem CT, invisibilizando os demais grupos. Observamos a possível presença de um padrão desigual em gênero e cor acerca de pessoas que fazem CT em todos os LD analisados. Indicamos a necessidade de mudança na representatividade desses personagens nos LD, considerando que mulheres e pessoas com cor diferente da branca, também, possuem sucesso nesse ramo e carecem dessa representação.

Oocyte vitrification is crucial for livestock reproduction, germplasm conservation, and human-assisted reproduction, but the overabundance of lipids is highly detrimental to oocyte development. It is necessary to reduce the lipid droplet content of oocytes before cryopreservation. This study analyzed the impact of β-nicotinamide mononucleotide (NMN), berberine (BER), or cordycepin (COR) on various aspects of bovine oocytes, including lipid droplet content and the expression levels of genes related to lipid synthesis in bovine oocytes, development ability, reactive oxygen species (ROS), apoptosis, and the expression levels of genes associated with endoplasmic reticulum (ER) stress, and mitochondrial function in vitrified bovine oocytes. The results of our study indicated that 1 μM NMN, 2.5 μM BER, and 1 μM COR were effective in reducing the lipid droplet content and suppressing the expression levels of genes involved in lipid synthesis in bovine oocytes. Our findings showed that the vitrified bovine oocytes treated with 1 μM of NMN had a significantly higher survival rate and better development ability compared to the other vitrified groups. Additionally, 1 μM NMN, 2.5 μM BER, and 1 μM COR decreased the levels of ROS and apoptosis, decreased the mRNA expression levels of genes involved in ER stress and mitochondrial fission but increased the mRNA expression levels of genes associated with mitochondrial fusion in the vitrified bovine oocytes. Our study results suggested that 1 μM NMN, 2.5 μM BER, and 1 μM COR effectively decreased the lipid droplet content and enhanced the development ability of vitrified bovine oocytes by lowering ROS levels, reducing ER stress, regulating mitochondrial function, and inhibiting apoptosis. Furthermore, the results showed that 1 μM NMN was more effective than 2.5 μM BER and 1 μM COR.

Office-based work today involves dealing with email, despite being denigrated and lauded in almost equal measures. Using the Conservation of Resources theory we examine whether Extraversion (expressed through two facets) acts as a resource to explain the differential impact that work-email has on people's energy resources (relating to fatigue and boredom). An experience-sampling study was undertaken, whereby 54 knowledge-workers completed records of their response (n = 589) to new work-email over the course of a typical working day. Results were analysed using hierarchical linear modelling (HLM). Participants who felt tired prior to dealing with email, reported that they felt more energized afterwards (but only if they were higher on Agentic extraversion). Work-email did not re-energize extraverts when they had been bored beforehand. By examining changes in energy resources, and by measuring different facets of Extraversion, we offer theoretical and methodological contributions to advancing understanding about the role of resources in dealing with work-email. Specifically, our results suggest that Extraversion may not constitutionally be a key resource within COR, because its value and contribution to resource building is contingent on context. Implications for practitioners concerned with how best to manage digital communications at work, are discussed. [ABSTRACT FROM AUTHOR]
