Adição de nanopartículas de Ti em matriz de Fe através da deposição por magnetron sputtering

Microalloyed steels constitute a specific class of steel with low amount of carbon and microalloying elements such as Vanadium (V), Niobium (Nb) and Titanium (Ti). The development and application of microalloyed steels and steels in general are limited to the handling of powders with particles of submicron or nanometer dimensions. Therefore, this work presents an alternative in order to construction of microalloyed steels utilizing the deposition by magnetron sputtering technique as a microalloying element addiction in which Ti nanoparticles are dispersed in an iron matrix. The advantage of that technique in relation to the conventional metallurgical processes is the possibility of uniformly disperse the microalloying elements in the iron matrix. It was carried out deposition of Ti onto Fe powder in high CH4, H2, Ar plasma atmosphere, with two deposition times. After the deposition, the iron powder with nanoparticles of Ti dispersed distributed, were compacted and sintered at 1120 ° C in resistive furnace. Characterization techniques utilized in the samples of powder before and after deposition of Ti were Granulometry, Scanning Electron Microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (DRX). In the case of sintered samples, it was carried out characterization by SEM and Vickers Microhardness assays. The results show which the deposition technique by magnetron sputtering is practicable in the dispersion of particles in iron matrix. The EDX microanalysis detected higher percentages of Ti when the deposition were carried out with the inert gas and when the deposition process was carried out with reactive gas. The presence of titanium in iron matrix was also evidenced by the results of X-ray diffraction peaks that showed shifts in the network matrix. Given these results it can be said that the technique of magnetron sputtering deposition is feasible in the dispersion of nanoparticles of iron matrix in Ti.

Formulação de grautes leves para a cimentação de poços de petróleo onshore

Grautes are dry mixes with hydraulic characteristics widely used in construction. This material comprises cement, mineral additives and dosed in accordance with the desired properties. The use of grautes in cementing oil wells potentially increases the precision in the composition of the mixture, since it is requires only the addition of the mixing water before its pumping. Such benefit may be availed in cementing wells since the formulations grautes meet the temperature and pressure characteristics typical of wells. The objective of this study is to evaluate the effect of adding different percentages of industrial minerals properties of light grautes for onshore oil wells. For the formulation of the employees were grautes light industrial minerals and waste minerals abundant in the Northeast, in addiction to Portland cement and chemical additives Special class. Grautes were formulated with densities between 1.55 g/cm3 (13.0 lb/gal) and 1.68 g/cm3 (14 lb/gal). Tests results showed that grautes with higher density in the range studied meet the specifications for cementation of shallow wells onshore. The compositions lighter can also be adjusted for applying the material in the cementation of oil wells

Prevenção primária da toxicodependência, "Do Ministério à Escola"

Neste estudo realiza-se uma reflexão crítica em torno da investigação-ação desenvolvida na Escola Secundária D. Dinis, por ocasião do Estágio. A investigação-ação pretendeu contribuir para a resposta à questão: «Em que medida é que as atividades de complemento curricular podem apoiar a alteração de comportamentos dos alunos face à Toxicodependência?» A amostra do estudo foi constituída por quarenta e um alunos, com idades compreendidas entre os quinze e os vinte e um anos, tendo a maioria dezasseis ou dezassete anos de idade. Os métodos e os instrumentos utilizados caraterizaram-se pela realização da atividade em cabanas de Tavira, a aplicação dos questionários antes e depois da atividade em Tavira e por último, a realização de uma conversa com os alunos envolvidos após a atividade acerca da prevenção primária da toxicodependência. Foram implementadas ações, no seio escolar, que permitiram envolver alunos, professores e funcionários, no sentido de realizar uma Prevenção Primária da Toxicodependência, em Tavira, com um conjunto de alunos da Escola Secundária D. Diniz. O impato [sic] das atividades foram estimadas a partir das diferenças das perceções dos alunos à entrada e saída das ações, face à temática em questão. Foi ainda analisada a formação desenvolvida e ainda uma “conversa” após a atividade, em jeito de balanço. A reflexão crítica foca-se no impato que a investigação-ação teve nos alunos, na comunidade escolar e no nosso desenvolvimento profissional, recorrendo-se à experiência vivida e à teoria para a sua fundamentação.

Behavioral traits predicting cocaine-conditioned place reference in mice: role of anxiety adn the basolateral amygdala

Aims. The individual susceptibility to cocaine addiction, a factor of interest in the understanding and prevention of this disorder, may be predicted by certain behavioral traits. However, these are not usually taken into account in research, making it difficult to identify whether they are a cause or a consequence of drug use. Methods. Male C57BL/6J mice underwent a battery of behavioral tests (elevated plus maze, hole-board, novelty preference in the Y maze, episodic-like object recognition memory and forced swimming test), followed by a cocaine-conditioned place preference (CPP) training to assess the reinforcing effect of the drug. In a second study, we aimed to determine the existence of neurobiological differences between the mice expressing high or low CPP by studying the number of neurons in certain addiction-related structures: the medial prefrontal cortex, the basolateral amygdala and the ventral tegmental area. Results. Anxiety-like behaviors in the elevated plus maze successfully predicted the cocaine-CPP behavior, so that the most anxious mice were also more likely to search for cocaine in a CPP paradigm. In addition, these mice exhibited an increased number of neurons in the basolateral amygdala, a key structure in emotional response including anxiety expression, without differences in the others regions analyzed. Conclusions. Our results suggest a relevant role of anxiety as a psychological risk factor for cocaine vulnerability, with the basolateral amygdala as potential common neural center for both anxiety and addiction.

Effects of palmitoylethanolamide in cocaine-induced behaviours

Aims. Cocaine addiction is a chronically relapsing disorder characterized by the compulsion to seek and take the drug. Previous investigations have demonstrated that several drugs of abuse, as cocaine, can alter the levels of lipid-based signalling molecules such as the N-acylethanolamines (NAEs). In addition, NAEs levels in the brain are sensitive to cocaine self-administration and extinction training. In this context, this study aimed to investigate the effect of repeated and acute palmitoylethanolamide (PEA), an endogenous NAE, on the behavioural effects of cocaine using mouse models of conditioned reward and psychomotor activation. Methods. Using male C57BL/6J mice, the ability of repeated PEA injections (1 or 10 mg/kg i.p) to modulate the development of a conditioned place preference (CPP) and behavioural sensitization (BS) induced by cocaine (20 mg/kg i.p.) was evaluated. In addition, the expression of cocaine-induced CPP and BS after acute PEA administration was also studied. Results. PEA (1 and 10 mg/kg i.p) significantly reduced the development of cocaine-induced BS, but did not modify the acquisition of cocaine-induced CPP. Furthermore, both doses of PEA were able to reduce the expression of BS and CPP. Conclusions. Altogether, these findings show that exogenous administration of PEA attenuated psychomotor activation and impaired the expression of CPP induced by cocaine. Our results may be relevant in order to understand the role of NAEs in the development and treatment of cocaine addiction.

Efeito da adição de fibras da palma do licuri (syagrus coronata) no comportamento físico e mecânico de compósitos de matriz cimentícia

This research was motivated by the requirement of asbestos s replacement in building systems and the need to generate jobs and income in the country side of the state of Bahia, Brazil. The project aimed at using fibers from licuri leaves (syagrus coronata), an abundant palm in the region, to produce composites appropriate for the sustainable production of cement fibre reinforced products in small plants. The composites were produced in laboratory using Portland cement CP-II-F32, sand, water, licuri palm fiber contents of 1.0, 1.5 and 2.0% by weight of binder (two different fiber length) and metakaolin. The latter was chosen as an additional binder for its efficiency to reduce the alkalinity of cementitious matrixes therefore preventing the degradation of vegetable fibers. The characterization of the composite components was carried out by sieving and laser particle size analyses, thermal analysis, fluorescence and X-ray diffraction. The composites performance was evaluated by 3- point-bending tests, compressive strength, ultrasound module of elasticity, free and restrained shrinkage, water capillarity absorption and apparent specific gravity. It has been found that the addition of fibers increased the time to onset of cracking over 200.00% and a 25% reduction in cracks opening in the restrained shrinkage test. The capillary absorption reduced about 25% when compared to fiber-free composites. It was also observed with regard to flexural strength, compressive strength and specific gravity, that the addiction of fibers did not affect the composite performance presenting similar results for compounds with and without fibers. In general it can be stated that the reinforced composite fibers of palm licuri presents physical and mechanical characteristics which enable them to be used in the intended proposals of this research

Fault Line

FAULT LINE examines the fragile humanity connected to the themes of sexuality, violence, addiction, family dynamics, and death. The book is not broken into sections; rather, as poems build upon one another to explore a narrative arc, FAULT LINE tracks a single speaker’s experience from girlhood to the verge of independent womanhood. The speaker employs formal structures such as the prose poem, sestina, and particularly the list poem to examine the fluidity of inner experience and also the culture at large while challenging the narrow definitions of femininity and masculinity. FAULT LINE works to not only address the question of blame but also the literal breaks in lines of poetry. By looking at a single speaker’s struggle, the book, like life, is both humorous and horrifying.

The Influence of Neurocognitive Impairment, Alcohol and other Drug (AOD) Use, and Psychosocial Factors on Antiretroviral Treatment Adherence, Service Utilization and Viral Load Among HIV-Seropositive Adults

Among people living with HIV (PLWH), adherence to antiretroviral therapy (ART) can be affected by problems of neurocognitive (NC) impairment, stress, alcohol and other drug (AOD) abuse, and other barriers. The aims of this research were to: (1) examine factors associated with NC impairment, (2) explore relationships between psychosocial variables with ART adherence and viral load (VL), and (3) evaluate the efficacy of an evidence-based intervention in improving ART adherence, increasing service utilization, and decreasing VL. The first study (n=370) was cross sectional and used structural equation modeling to test whether AOD use, years living with HIV, and time from HIV diagnosis to seeking care were associated with poorer NC functioning. The second study (n=246) used similar methods to test the hypothesis that stress, barriers to adherence, NC impairment, poor social support, and AOD use were related to lower VL mediated by ART adherence. The third study (n=243) evaluated an evidence-based, eight-session program to improve ART adherence, reduce VL, and increase service utilization in a randomized controlled trial. Study participants were PLWH living in South Florida, 18 to 60 years old, with a history of alcohol abuse enrolled from January 2009 through November 2012. Secondary analysis of available data showed: (1) scores on interference with executive functioning increased by 0.32 for each day of marijuana use and 1.18 for each year living with HIV, but no association was found between alcohol use and NC functioning; (2) each barrier to adherence was associated with a 10% decrease in adherence to ART and a 0.42 unit increase in VL (log10) and the relationship between barriers and VL was partially mediated by ART adherence; (3) participants in the evidence-based program were more likely than the comparison group to report an undetectable VL (OR=2.25, p Psychosocial factors affect VL, but ART adherence is essential in achieving an undetectable VL in PLWH.

Gambling and violence in a nationally representative sample of UK men

The relationship between violence and problem gambling in general population samples is under-researched and requires further attention to inform treatment and prevention efforts. We investigated the relationship between gambling problems and violence among men and sought to determine if the link can be accounted for by mental disorders, alcohol and drug dependence and impulsivity.

O uso excessivo da Internet e a sua relação com Sintomatologia Psicopatológica

O uso excessivo da internet tem vindo a ser estudado por vários países estrangeiros desde a década de noventa. Apesar do crescente interesse neste ramo de investigação, em Portugal esta área continua pouco desenvolvida. O presente estudo procurou testar a existência de associações entre o uso excessivo da internet e a sintomatologia psicopatológica, bem como avaliar as relações entre a utilização excessiva da internet e os dados sociodemográficos recolhidos. Participaram neste estudo um total de 549 indivíduos portugueses (151 homens e 398 mulheres), com idades compreendidas entre os 18 e os 65 anos (X̅ = 27.0), onde foi preenchida a versão portuguesa do Internet Addiction Test (Young, 1998); o Brief Sympton Inventory (Canavarro, 1999); e o questionário sociodemográfico. Os resultados revelaram que a utilização excessiva da internet encontra-se associada positivamente não só a sintomas psicopatológicos, mas também a fatores sociodemográficos como o sexo do participante, o estado civil, a idade e as habilitações literárias. Deste modo, foi referida a importância da prevenção e da intervenção precoce da utilização excessiva da internet na população jovem. Também é essencial alargar o campo de investigação a este novo fenómeno mundial.
