Influência do teor de cinza volante na reologia de argamassa de assentamento: fabricado com reciclagem de resíduos

As argamassas podem ser consideradas como um conjunto de partículas sólidas em suspensão (agregado miúdo), aglomerantes e água (pasta de cimento). Sendo assim, seu comportamento reológico durante a cura pode ser influenciado por fatores como a granulometria, composição e teor de água incorporado. Este trabalho estudou as características reológicas de seis composições de argamassas, em função do teor de cinza volante, como material de atividade pozolânica, em substituição parcial do cimento. A argamassa estudada utilizou como base agregado o resíduo da construção civil (RCC), devidamente caracterizado por difratometria e fluorescência de raios-X. Formularam-se composições de argamassas para os ensaios reológicos com adição de resíduo de construção civil (RCC) nas proporções de 95, 90, 85, 80, 75 e 70%; cinzas volantes (CV) 0, 5, 10, 15, 20 e 25% e 5% de Cimento Portland Comum (CP II- E 32), sendo que em cada amostra foi incorporado 35% de água. Utilizou-se o viscosímetro modelo VT 550, com sensor tipo cilindros coaxiais SV₁ – Haake a temperatura de 28ºC. Para avaliar o tempo de cura do material programou-se uma taxa de cisalhamento constante 53,4 s^-1 em 1h e 45min, sendo avaliado o torque em intervalos de 15min. Para a elaboração das curvas de fluxo e curvas de histerese, utilizou-se a taxa de cisalhamento entre 0 e 600 s^-1 no intervalo de tempo de 120s. Os resultados mostraram que a incorporação de cinza volante foi o principal fator para aumento do torque no tempo de cura das argamassas e mudança do comportamento de reópetico para tixotrópico, nos traços analisados. Os dados experimentais das formulações propostas ajustaram-se ao modelo reológico de Herschel-Bulkley.

Vulnerabilidade ao HIV em estudantes de ensino médio de uma escola pública do interior de São Paulo

Introduction: sexuality is an inherent dimension in the human being, which is present in all stages of his development. However, it becomes relevant during the adolescence as it often sets the beginning of the individuals` sexual life. Objective: this study aimed at identifying the behaviors of adolescents regarding the HIV vulnerability, considering the differences between genders. Methods: it was used a structured questionnaire proposed by the Ministry of Health and Ministry of Education of Brazil with the title “Do I need to text for HIV?” Sample included 136 high school students in the inner state of São Paulo. Results: the results showed an increase in adolescents’ vulnerability to HIV, that is: 59.5% of the participants are in a vulnerable situation. Regarding the gender, research showed that women (33.1%) are more vulnerable than men (26.5%). Conclusion: it is observed that the lack of information is a reality that increases the vulnerability of adolescents, but it is also observed that the mere acquisition of information does not necessarily guarantee behavior change nor HIV prevention.

Efeitos de instrução e de treino parental em cuidadores de crianças com câncer

Esta pesquisa teve como objetivo analisar os efeitos de instrução e de treino parental sobre comportamentos observados em cuidadores e em crianças com diagnóstico de câncer durante procedimento de punção venosa em ambulatório. Participaram nove cuidadores em três condições (Rotina, Manual e Treino). Fez-se análise de características familiares, estilo parental, efeitos de um manual de instruções e de treino parental, com sessões de observação direta do comportamento durante punção venosa. Os resultados apontam efeito positivo do manual para mudança de comportamento em curto prazo. Após treino parental, observou-se aumento nas taxas de monitoria positiva do cuidador, com relatos de generalização desses comportamentos para outros contextos. Discute-se a importância do estilo parental como fator de proteção à criança com câncer.

Compensatory Health Beliefs Predict Maladaptive Coping, Impulsivity, and Erroneous Health Perceptions

Compensatory Health Beliefs (CHB) are a common strategy used to reduce the cognitive discomfort that arises from participating in recognizably unhealthy behaviors. The current research examines relationships between CHB and other cognitive variables. Data was collected in two phases, using survey methodology. Study 1 explored relationships between the use of CHB, impulsiveness, and coping styles. Study 2 expanded the inquiry by exploring relationships to health perception and knowledge. Results revealed that participants who scored high on overall CHB were more likely to: engage in maladaptive coping strategies (r = .47, p < .01) [including avoidant coping styles (r = .38, p < .01) and unhealthy coping styles (r = .47, p < .01)], score higher on measures of impulsivity (r = .43, p < .01), be well-informed about their general health (r =-.21, p < .05), eat fast food more often ( r = p < .05), and consider it safe to smoke more frequently (r = .18, p < .05). Participants with lower CHB scores considered themselves more well-informed about their general health (r = -.21, p < .05), including understanding the minimum recommended amounts of physical activity needed to maintain health (r = -.35, p < .01 ), and knowing the health risks of stress ( r = -.19, p < .05). In addition, maladaptive coping was positively correlated with lack of general health knowledge (r = -.22 p < .01), less understanding of the risks of stress and alcohol (r = .20, p < .05), less knowledge of the recommended daily amounts of physical activity needed for health (r = -.26, p < .01), less frequent exercise (r = -.26, p < .01 ), and generally more unhealthy daily habits (r = -.26, p < .01). These findings contribute to a new area of investigation and may be useful to those who want to motivate behavior change.

Efficacy of brief alcohol screening intervention for college students (BASICS): a meta-analysis of randomized controlled trials

Background: Many studies reported that brief interventions are effective in reducing excessive drinking. This study aimed to assess the efficacy of a protocol of brief intervention for college students (BASICS), delivered face-to-face, to reduce risky alcohol consumption and negative consequences. Methods: A systematic review with meta-analysis was performed by searching for randomized controlled trials (RCTs) in Medline, PsycInfo, Web of Science and Cochrane Library databases. A quality assessment of RCTs was made by using a validated scale. Combined mean effect sizes, using meta-analysis random-effects models, were calculated. Results: 18 studies were included in the review. The sample sizes ranged from 54 to 1275 (median = 212). All studies presented a good evaluation of methodological quality and four were found to have excellent quality. After approximately 12 months of follow-up, students receiving BASICS showed a significant reduction in alcohol consumption (difference between means = -1.50 drinks per week, 95% CI: -3.24 to -0.29) and alcohol-related problems (difference between means = -0.87, 95% CI: -1.58 to -0.20) compared to controls. Conclusions: Overall, BASICS lowered both alcohol consumption and negative consequences in college students. Gender and peer factors seem to play an important role as moderators of behavior change in college drinking. Characteristics of BASICS procedure have been evaluated as more favorable and acceptable by students in comparison with others interventions or control conditions. Considerations for future researches were discussed.

Estágios de mudança de comportamento e fatores associados à prática de atividade física em indivíduos com claudicação intermitente

OBJECTIVE: To analyze, in people with intermittent claudication, the frequency of individuals who are in each of stages of health behavior change to practice physical activity, and analyze the association of these stages with the walking capacity. METHODS: We recruited 150 patients with intermittent claudication treated at a tertiary center, being included those >30-year-old-individuals and who had ankle-arm index <0.90. We obtained socio-demographic information, presence of comorbidities and cardiovascular risk factors and stages of health behavior change to practice physical activity through a questionnaire, they being pre-contemplation, contemplation, preparation, action and maintenance. Moreover, the walking capacity was measured in a treadmill test (Gardner protocol). RESULTS: Most individuals were in the maintenance stage (42.7%), however, when the stages of health behavior change were categorized into active (action and maintenance) and inactive (pre-contemplation, contemplation and preparation),51.3% of the individuals were classified as inactive behavior. There was no association between stages of health behavior change, sociodemographic factors and cardiovascular risk factors. However, patients with intermittent claudication who had lower total walking distance were three times more likely to have inactive behavior. CONCLUSION: Most patients with intermittent claudication showed an inactive behavior and, in this population, lower walking capacity was associated with this behavior.

The influence of petrogenetic processes on the composition of Ocean Island Basalts

Ocean Island Basalts (OIB) provide important information on the chemical and physical characteristics of their mantle sources. However, the geochemical composition of a generated magma is significantly affected by partial melting and/or subsequent fractional crystallization processes. In addition, the isotopic composition of an ascending magma may be modified during transport through the oceanic crust. The influence of these different processes on the chemical and isotopic composition of OIB from two different localities, Hawaii and Tubuai in the Pacific Ocean, are investigated here. In a first chapter, the Os-isotope variations in suites of lavas from Kohala Volcano, Hawaii, are examined to constrain the role of melt/crust interactions on the evolution of these lavas. As 187Os/188Os sensitivity to any radiogenic contaminant strongly depend on the Os content in the melt, Os and other PGE variations are investigated first. This study reveals that Os and other PGE behavior change during the Hawaiian magma differentiation. While PGE concentrations are relatively constant in lavas with relatively primitive compositions, all PGE contents strongly decrease in the melt as it evolved through ~ 8% MgO. This likely reflects the sulfur saturation of the Hawaiian magma and the onset of sulfide fractionation at around 8% MgO. Kohala tholeiites with more than 8% MgO and rich in Os have homogeneous 187Os/188Os values likely to represent the mantle signature of Kohala lavas. However, Os isotopic ratios become more radiogenic with decreasing MgO and Os contents in the lavas, which reflects assimilation of local crust material during fractional crystallization processes. Less than 8% upper oceanic crust assimilation could have produced the most radiogenic Os-isotope ratios recorded in the shield lavas. However, these small amounts of upper crust assimilation have only negligible effects on Sr and Nd isotopic ratios and therefore, are not responsible for the Sr and Nd isotopic heterogeneities observed in Kohala lavas. In a second chapter, fractional crystallization and partial melting processes are constrained using major and trace element variations in the same suites of lavas from Kohala Volcano, Hawaii. This inverse modeling approach allows the estimation of most of the trace element composition of the Hawaiian mantle source. The calculated initial trace element pattern shows slight depletion of the concentrations from LREE to the most incompatible elements, which indicates that the incompatible element enrichments described by the Hawaiian melt patterns are entirely produced by partial melting processes. The “Kea trend” signature of lavas from Kohala Volcano is also confirmed, with Kohala lavas having lower Sr/Nd and La/Th ratios than lavas from Mauna Loa Volcano. Finally, the magmatic evolution of Tubuai Island is investigated in a last chapter using the trace element and Sr, Nd, Hf isotopic variations in mafic lava suites. The Sr, Nd and Hf isotopic data are homogeneous and typical for the HIMU-type OIB and confirms the cogenetic nature of the different mafic lavas from Tubuai Island. The trace element patterns show progressive enrichment of incompatible trace elements with increasing alkali content in the lavas, which reflect progressive decrease in the degree of partial melting towards the later volcanic events. In addition, this enrichment of incompatible trace elements is associated with relative depletion of Rb, Ba, K, Nb, Ta and Ti in the lavas, which require the presence of small amount of residual phlogopite and of a Ti-bearing phase (ilmenite or rutile) during formation of the younger analcitic and nephelinitic magmas.

[Tobacco use prevention and cessation in the dental practice]

This is the fourth part of a series of publications from the Swiss task force named "Smoking--intervention in the private dental office" on the topic "tobacco use and dental medicine". It presents the implementation of tobacco use prevention and cessation in the dental practice. Next to the optimal performance of plaque control, tobacco use cessation has become the most important measure for the treatment of periodontal diseases. In contrast to general medicine practice, the dental practice team is seeing its patients regularly and is therefore capable of helping their patients quit tobacco use. Tobacco dependence consists of both a physical and a psychological dependence. Therefore, the combination of pharmacotherapy with behavior change counseling is recommended. The use of brief Motivational Interviewing (BMI) for tobacco use short interventions in the dental practice appears to be suitable. Nicotine replacement therapy (NRT) is the treatment of choice for the dental practice team because both Varenicline and Bupropion SR have to be prescribed by physicians.
