Caracterização de resíduos oriundos do beneficiamento do minério de ferro para uso em pavimentação

Mining in Brazil has a key role in economic and social development, contributing directly to improve the lives of the population. However, the mining activity even if done responsibly and with a proper study of waste management to reduce the impact of its effects, may cause harmful damage to the environment. Other forms of pollution are also caused due to mining activity. The visual pollution caused by the waste storage at open sky, in addition to the noise pollution caused by the excessive noise of the machines both in the extraction of ore, as in processing. An alternative way to lessen the environmental impacts caused by mining is the use of waste in layers that will compose the pavements along the highways. Thus, this work sets out to give a proper disposal of the wastes from the processing of iron ore, resulting from the mining activity of the group of mining Mhag Services and Mining S/A, in the mine of Bonito, located in Jucurutu, a town in the state of Rio Grande do Norte. The residues of the iron ore were stabilized with a granular soil from the city of Macaiba, also in the state of Rio Grande do Norte, which is being used in the duplication of the BR-304 referring to the entitled passage of Reta Tabajara. The present work was developed in three stages, being the first one divided by the chemical and mineralogical tests, by the tests of physical characterization and by the tests of paving for the residues of the iron ore. The second stage corresponds to the same tests being performed for granular soil. The third stage includes the essays abovementioned for three different mixtures of iron ore waste and granular soil, being they: 15% of iron-ore waste and 85% of granular soil, 25% of iron-ore waste and 75% of granular soil, 50% of iron-ore waste and 50% of granular soil. The technical feasibility of using waste from the iron ore beneficiation was checked, compressed in the intermediate energy and modified for use in base layers, sub-base, reinforcement subgrade and subgrade. The incorporation of the residues originating from the improvement of the iron ore in highways will provide an alternative to the use of aggregate conventionally used in the paving, besides preserving the environment.

Mecanismos de sincronia social no ritmo circadiano de atividade durante a coabitação em casais de saguis (Callithrix jacchus)

In marmosets, it was observed that the synchrony among circadian activity profiles of animals that cohabite in family groups is stronger than those of the same sex and age of different families. Inside the group, it is stronger between the younger ones than between them and their parents. However, the mechanisms involved in the social synchrony are unknown. With the aim to investigate the synchronization mechanisms involved in the synchrony between the circadian activity profiles during cohabitation in pairs of marmosets, the motor activity was continuously registered by the use of actmeters on three dyads. The pairs were maintained in two different conditions of illumination: light-dark cycle LD 12:12 (LD cohabitation I – 21 days), and thereafter in LL (~350 lux). Under LL, the pairs were submitted to four experimental situations: 1. Cohabitation (LLJ I – 24 days), 2. Removal of one member of the pair to another room with similar conditions (LLS I – 20 days), 3. Reintroduction of the separated member in the cage of the first situation (LLJ II – 30 days) and 4. Removal of a member from each pair to another experimental room (LLS II – 7 days), to evaluate the mechanisms of synchronization. Ultimately, the members of each pair were reintroduced in the cage and were kept in LD cycle 12:12 (LDJ II – 11 days). The rhythms of pairs free-ran in LL, with identical periods between the members of each pair during the two stages of cohabitation. In the stages in which the animals were separated, only the rhythms of two females free-ran in the first stage and of three animals in the second one. In those conditions, the rhythms of animals of each pair showed different endogenous periods. Besides, during cohabitation in LD and LL, the members of each pair showed a stable phase relationship in the beginning of the active phase, while in the stages in which the animals were separated it was noticed a breaking in the stability in the phase relationships between the circadian activity profiles, with an increase in the difference in the phase angles between them. During cohabitation, at the transition between LD and LL, all animals showed free-running rhythms anticipating progressively the beginning and the end of the active phase in a phase similar to the previous condition, showing signs of entrainment to the previous LD. While in the posterior stages this was observed in only three animals between: LLT I and LLS I, and LLT II and LLS II, evidencing signs of entrainment to social cues between the members of each pair. On the other hand, one animal delayed progressively between LLT I and LLS I, three animals delayed between LLS I and LLT II, and three animals between LLT II and LLS II, perhaps by entrainment to the animals maintained outdoors in the colony. Similar process was observed in four animals between LLS II and LDT II, indicating entrainment to LD. In the transition between LLS I and LLT II, signs of masking was observed in the rhythm of a female in response to the male and in another pair in the rhythm of the male in regard to that of the female. The general and maximum correlations in the circadian activity profiles were stronger during cohabitation in LD and LL than in the absence of social contact in LL, evidencing the social effect. The cohabiting pairs had higher values of the maximum correlation in LD and LL than when the profiles were correlated to animals of different cages, with same or different sexes. Similar results were observed in the general correlation. Therefore, it is suggested that cohabitation induces a strong synchrony between circadian activity profiles in marmosets, which involves entrainment and masking. Nevertheless, additional studies are necessary to evaluate the effect of social cues on the synchronization of the circadian rhythm in pairs of marmosets in the absence of external social cues in order to confirm this hypothesis.

Caracterização do ritmo circadiano de atividade e repouso em saguis idosos (Callithrix Jacchus)

Advanced age may become a limiting factor for the maintenance of rhythms in organisms, reducing the capacity of generation and synchronization of biological rhythms. In this study, the influence of aging on the expression of endogenous periodicity and synchronization (photic and social) of the circadian activity rhythm (CAR) was evaluated in a diurnal primate, the marmoset (Callithrix jacchus). This study had two approaches: one with longitudinal design, performed with a male marmoset in two different phases: adult (three years) and older (9 y.o.) (study 1) and the second, a transversal approach, with 6 old (♂: 9.7 ± 2.0 y.o.) and 11 adults animals (♂: 4.2 ± 0.8 y.o.) (study 2). The evaluation of the photic synchronization involved two conditions in LD (natural and artificial illuminations). In study 1, the animal was subjected to the following stages: LD (12:12 ~ 350: ~ 2 lx), LL (~ 350 lx) and LD resynchronization. In the second study, the animals were initially evaluated in natural LD, and then the same sequence stages of study 1. During the LL stage in study 2, the vocalizations of conspecifics kept in natural LD on the outside of the colony were considered temporal cue to the social synchronization. The record of the activity was performed automatically at intervals of five minutes through infrared sensor and actimeters, in studies 1 and 2, respectively. In general, the aged showed a more fragmented activity pattern (> IV < H and > PSD, ANOVA, p < 0.05), lower levels of activity (ANOVA, p < 0.05) and shorter duration of active phase (ANOVA, p < 0.05) in LD conditions, when compared to adults. In natural LD, the aged presented phase delay pronounced for onset and offset of active phase (ANOVA, p < 0.05), while the adults had the active phase more adjusted to light phase. Under artificial LD, there was phase advance and greater adjustment of onset and offset of activity in relation to the LD in the aged (ANOVA, p < 0.05). In LL, there was a positive correlation between age and the endogenous period () in the first 20 days (Spearman correlation, p < 0.05), with prolonged  held in two aged animals. In this condition, most adults showed free-running period of the circadian activity rhythm with  < 24 h for the first 30 days and later on relative coordination mediated by auditory cues. In study 2, the cross-correlation analysis between the activity profiles of the animals in LL with control animals kept under natural LD, found that there was less social synchronization in the aged. With the resubmission to the LD, the resynchronization rate was slower in the aged (t-test; p < 0.05) and in just one aged animal there was a loss of resynchronization capability. According to the data set, it is suggested that the aging in marmosets may be related to: 1) lower amplitude and greater fragmentation of the activity, accompanied to phase delay with extension of period, caused by changes in a photic input, in the generation and behavioral expression of the CAR; 2) lower capacity of the circadian activity rhythm to photic synchronization, that can become more robust in artificial lighting conditions, possibly due to the higher light intensities at the beginning of the active phase due to the abrupt transitions between the light and dark phases; and 3) smaller capacity of non-photic synchronization for auditory cues from conspecifics, possibly due to reducing sensory inputs and responsiveness of the circadian oscillators to auditory cues, what can make the aged marmoset most vulnerable, as these social cues may act as an important supporting factor for the photic synchronization.

Origem do plexo lombossacral e seus nervos em quatis (Nasua nasua, LINNAEUS, 1766)

The objective of this research is to study the origin of the lumbosacral plexus and its nerves in coatis (Nasua nasua). Six adult specimens, three males and three females, were used in this research. The animals were donated by IBAMA / GO or were collected when found dead by the edges of highways in Southeast Goiás. The specimens were fixed in aqueous 10% formaldehyde solution and preserved in the same solution. The observations reveal that the lumbosacral plexus of the coati has a structure with few intercommunications between its components. There are no typical handle formations, but the roots or its branches converge to form the nerves that are driven to the pelvic limb. The components of the Lumbosacral Plexus are ventral branches of L4 to S3. The Lumbosacral plexus generates several short nerves destined to pelvic structures and, at the same time, three long nerves: femoral, obturator and sciatic, all destined to the hind limb.

Este estudo objetivou conhecer a incidência do evento queda e identificar a presença de seus principais fatores de risco. Estudo exploratório, realizado de março a novembro/2009, com aplicação de um formulário sobre quedas em um grupo de idosos. Os dados foram analisados por cálculo de frequências, média e desvio-padrão. Participaram 62 idosos, 41,9% relataram queda nos últimos seis meses, a maioria mulheres. Identificou-se ocorrência de agravos concomitantes: visão regular, audição boa, polifarmácia, IMC normal, forte força de preensão palmar e condições dos pés adequadas. Na maioria dos que caiu, o desequilíbrio foi apontado como principal motivo. A queda ocorreu mais no período da manhã, em local de piso áspero e seco, sem degraus, rampas ou tapetes, iluminação adequada e o tipo de calçado mais utilizado foi chinelo de borracha. Percebe-se a alta ocorrência das quedas na população idosa, fato que fundamenta a necessidade de avaliação das condições de risco envolvidas

Gestão de energia em ambiente industrial

A Sociedade da Água de Luso, S.A., localizada no concelho de Mealhada, é uma empresa do setor do engarrafamento de águas minerais naturais, de nascente e de consumo humano. Esta realiza as suas atividades, tendo em consideração a eficiência energética, ao longo do seu processo produtivo. Desta forma, o trabalho desenvolvido teve como objetivo o acompanhamento da implementação do sistema de monitorização e recolha de dados, que posteriormente foi útil na redução dos consumos energéticos (consumo de ar comprimido). Para além disto, também foi proposta uma medida de eficiência energética que visa a redução de energia elétrica na área da iluminação. O sistema de monitorização e recolha de dados e a criação de uma equipa de redução do consumo de ar comprimido permitiram a identificação das áreas de atuação, a monitorização das metas estipuladas no âmbito da equipa e a detecção de anomalias. A medida de eficiência energética aplicada incide na substituição de lâmpadas fluorescentes tubulares T8 por lâmpadas fluorescentes tubulares T5. Assim, a implementação deste sistema e a aplicação das medidas de eficiência energética na rede de ar comprimido no âmbito da equipa permitiram uma redução de 0,03 kWh/hL o que significa uma poupança de 5.600 € em quinze semanas. Ao nível da iluminação as medidas sugeridas permitem uma redução de 8.945 kWh/ano o que corresponde a uma poupança de 1.055 €/ano.

A influência de decisões arquitetônicas na eficiência energética do Campus vol. 1/UFRN

Building design is an effective way to achieve HVAC energy consumption reduction. However, this potentiality is often neglected by architects due to the lack of references to support design decisions. This works intends to propose architectural design guidelines for energy efficiency and thermal performance of Campus/UFRN buildings. These guidelines are based on computer simulations results using the software DesignBuilder. The definition of simulation models has begun with envelope variables, partially done after a field study of thirteen buildings at UFRN/Campus. This field study indicated some basic envelope patterns that were applied in simulation models. Occupation variables were identified with temperature and energy consumption monitoring procedures and a verification of illumination and equipment power, both developed at the Campus/UFRN administration building. Three simulation models were proposed according to different design phases and decisions. The first model represents early design decisions, simulating the combination of different types of geometry with three levels of envelope thermal performance. The second model, still as a part of early design phase, analyses thermal changes between circulation halls lateral and central and office rooms, as well as the heat fluxes and monthly temperatures in each circulation hall. The third model analyses the influence of middle-design and detail design decisions on energy consumption and thermal performance. In this model, different solutions of roofs, shading devices, walls and external colors were simulated. The results of all simulation models suggest a high influence of thermal loads due to the incidence of solar radiation on windows and surfaces, which highlights the importance of window shading devices, office room orientation and absorptance of roof and walls surfaces

Contra as Secas: a engenharia e as origens de um planejamento regional no nordeste brasileiro

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

Medidas de eficiência energética numa indústria cerâmica

O presente relatório resulta de um estágio realizado no âmbito da eficiência energética assente no programa Galp 20-20-20 que tem por génese uma parceria entre a Universidade de Aveiro e a empresa de coberturas cerâmicas, CS – Coelho da Silva S.A. A Fábrica alvo de estudo é uma consumidora intensiva de energia, despendeu no ano de 2013 cerca de 3.768 tep. Devido aos seus processos de cozedura e secagem, apresenta uma elevada dependência de Gás Natural, representando pouco mais de 78% do consumo global da fábrica. Deste consumo de energia térmica, 83% respeita ao forno e os restantes 17% encontram-se alocados ao secador, pelo que as medidas de eficiência energética presentes neste relatório centram-se da redução deste vetor energético. São então propostas três medidas para a redução da dependência deste vetor. A primeira, incide na recuperação de calor residual presente nos gases de exaustão através da instalação de um permutador de calor. Esta medida permite uma redução do consumo na ordem dos 10% e conta com um payback de 2,3 anos resultante de uma economia anual de 150.000 €. Para este estudo foi desenvolvido um modelo dinâmico em excel que permite a simulação de diversos cenários. São também propostas mais duas intervenções que incidem na alteração do circuito térmico. Estas medidas têm um impacte mais reduzido no que respeita ao percentual de redução energético, ambas com menos de 1% de redução do consumo global da fábrica. Contudo são medidas bastante interessantes dada a sua simplicidade e contam com poupanças anuais na ordem dos 6.000 € que resultam num payback inferior a 2 meses. Paralelamente executaram-se dois estudos para a iluminação, o primeiro sugere a instalação de um modelador de tensão que reduz a potência de iluminação em 36%, implicando uma redução da iluminância de cerca de 5%. A redução da potência resulta numa economia energética na ordem dos 0,4% da energia global da instalação. Este equipamento poderá ser adquirido por completo ou em renting. Ao optar pela compra integral, o investimento será apenas ressarcido em 2,8 anos resultante de uma poupança anula de perto de 6.500 €. Caso seja por renting este não tem qualquer custo adicional e as economias monetárias são partilhadas entre a empresa que fornece o equipamento e a CS-Coelho da Silva, S.A. Por fim é sugerida a substituição de parte da iluminação atual da fábrica por tecnologia LED, com esta medida reduz-se o consumo global em 0,76%. Esta medida gera uma economia monetária na ordem dos 11.500 € sendo ressarcida em 2,1 anos.

Projeto de reabilitação energética de piscinas interiores

O presente relatório de projeto explicita as etapas da elaboração e os resultados obtidos através da realização de um projeto de reabilitação energética de um complexo de piscinas interiores. Esta reabilitação energética tem por objetivo a redução dos custos energéticos através da subtração de consumos supérfluos de energia ou da melhoria da eficiência energética dos equipamentos. Para alcançar estes objetivos recorreu-se à simulação dinâmica do edifício de modo a estimar múltiplas variáveis energéticas e identificar quais os setores e equipamentos que maior influência têm no consumo energético do complexo em estudo. Para a realização da simulação, recorreu-se a um software desenvolvido pelo DOE dos Estados Unidos da América, o Energy Plus, com o auxílio do Design Builder, que permite a criação e edição do modelo de forma mais fácil e acessível. Os valores retirados da simulação foram posteriormente comparados com valores reais. Com o complexo caraterizado e os principais consumidores identificados foi possível iniciar o estudo das medidas de melhoria da eficiência energética. As principais medidas estudadas incidiram na instalação de coberturas isotérmicas nas piscinas para reduzir a perda de energia através da evaporação e da radiação, a introdução de fontes de energia renovável como alternativa energética, substituição de elementos do sistema de iluminação e o aproveitamento de energia dissipada em equipamentos. Com este estudo, a entidade gestora do complexo encontra-se mais informada e pronta a tomar decisões que influenciem de forma significativa o consumo de energia no complexo, podendo optar pela instalação de alguma das medidas propostas.
