Modelagem computacional de dados magnetotelúricos marinhos 2-D

O presente trabalho tem como objetivo investigar o espalhamento das ondas planas causados pela variação lateral das propriedades físicas das rochas. Essa é uma das questões mais importante para o sucesso da exploração geofísica. O método geofísico usado nesta dissertação foi método magnetotelúrico (MT) e método Magnetotelúrico marinho (mMT). Umas das ferramentas utilizadas foram o método dos elementos finitos, este método é notável pela flexibilidade em resolver numericamente as equações diferenciais para campos eletromagnéticos secundários, gerados por estruturas geológicas com geometrias complexas, sendo utilizado para obter a solução numérica do espalhamento do campo eletromagnético da onda plana por um dique vertical (modelos bidimensionais). Os algoritmos desenvolvidos foram aplicados em diversos modelos de dique vertical, com diferentes parâmetros geoelétricos.

Utilização de fermento de descarte da indústria cervejeira na produção da aguardente de liquor de laranja

Utilização de fermento de descarte da indústria cervejeira na produção da aguardente de liquor de laranja. A indústria de suco de laranja produz ao final do processo um subproduto denominado "liquor" de laranja, que é gerado na operação de prensagem do bagaço, e após concentrado, é adicionado ao farelo de polpa cítrica peletizado (CPP) para a elaboração de ração animal. A indústria brasileira de cerveja, por sua vez, tem descartado anualmente cerca de 160 milhões de litros de fermento, ainda com boa viabilidade (com um percentual de células mortas inferior a 5%). A cerveja mais difundida no mercado brasileiro é a do tipo "larger", produzida por cepas S. uvarum, que são caracterizadas pela baixa fermentação e normalmente utilizadas no máximo de 4 a 10 gerações.

Leucograma e metabolismo oxidativo de neutrófilos em cabras da raça Saanen nos períodos de gestação, parto e pós-parto

The purpose of this study was to evaluate the leukocyte count and the oxidative metabolism of neutrophil in Saanen goats during periods of pregnancy, parturition and postpartum. Were used 20 Saanen goats, clinically healthy and serologically negative for caprine arthritis encephalitis virus (CAEV). Blood samples were collected by jugular venipuncture 49 (M1), 42 (M2), 35 (M3), 28 (M4), 21 (M5), 14 (M6), seven (M7), three (M8) days before the parturition, on the day of birth (M9), three (M10) and seven (M11) days postpartum, for the leukocyte count, and serum for cortisol, estradiol and progesterone determination. From 28 days (M4) before parturition until seven days postpartum (M11) blood samples were collected for evaluation of oxidative metabolism of neutrophils by the nitroblue tetrazolium reduction test (NBT). The results showed that at parturition day there were an increase in cortisol and estradiol levels and a decrease in progesterone serum, neutrophilic leukocytosis and left shift slight, decrease of lymphocytes, increase in the neutrophil: lymphocyte, eosinopenia, monocytosis and basophilia. There was a neutrophilic leukocytosis and an increase in the neutrophil: lymphocyte on the seventh day postpartum. There were not significant alterations in oxidative metabolism of neutrophils during pregnancy, parturition and postpartum. It was concluded that parturition causes an elevation in cortisol and estradiol levels and a decrease in progesterone serum determining a neutrophilic leukocytosis and left shift slight, with a reduction of lymphocytes, increase in the neutrophil:lymphocyte, eosinopenia, monocytosis and basophilia. Neutrophilic leukocytosis, increase in the neutrophil: lymphocyte and fibrinogen are detected on the seventh day postpartum. Pregnancy, parturition and the postpartum do not change the oxidative metabolism of neutrophils evaluated by NBT reduction test.

Resistência contra ectoparasitas em bovinos da raça Crioula Lageana e meio-sangue Angus avaliada em condições naturais

This study was carried out to evaluate the breed resistance against ectoparasites infestations in Crioula Lageana and crossbred Angus male calves under natural condition. Ten weaned and neutered male calves (6-8 months) of each group were kept together in winter and summer pastures in Monte Castelo, Santa Catarina State. Every 28 days, female ticks (Rhipicephalus (Boophilus) microplus) more than 4 mm long were counted on the right and left side of the body of each animal, as well as the D. hominis nodules. Coat thickness also was measured at each sampling and all animals were classified according coat color. Crioula Lageana group was less infested by D. hominis than crossbred Angus in five times and by ticks in the infestation peak (P<0.05). There were no differences in the distribution of the ticks and grubs between animal body sides. Dark-haired animal in both groups were the most susceptible.

Diretrizes para o desenvolvimento e a avaliação de blogs de biblioteca

Blogging become popular due to its ease of use and publication, which influences the growth of digital information environments. Therefore, studies are needed to optimize the organization of information in the blog, to contribute in its development. Using the direct observation of nonparticipatory, analysis was performed on 6 blogs of university libraries to identify the elements of Information Architecture (IA) that is considered essential and optional for the structural development of a blog. Thus, were conducted planning guidelines for blogs and a model for its evaluation, and were proposed specific elements of IA for blogs, to contribute to the study of Digital Information Architecture.

Diabete moderado induzido em diferentes fases da vida de ratas Wistar: repercussões na reprodução materna e na freqüência de anomalias fetais

Experimental models are necessary to elucidate pathophysiological mechanisms not yet understood in humans. To evaluate the repercussions of the diabetes, considering two methodologies, on the pregnancy of Wistar rats and on the development of their offspring. In the 1st induction, female offspring were distributed into two experimental groups: Group streptozotocin (STZ, n=67): received the β-cytotoxic agent (100mg STZ/kg body weight - sc) on the 1st day of the life; and Non-diabetic Group (ND, n=14): received the vehicle in a similar time period. In the adult life, the animals were mated. After a positive diagnosis of pregnancy (0), female rats from group STZ presenting with lower glycemia than 120 mg/dL received more 20 mg STZ/kg (ip) at day 7 of pregnancy (2nd induction). The female rats with glycemia higher than 120mg/dL were discarded because they reproduced results already found in the literature. In the mornings of days 0, 7, 14 and 21 of the pregnancy glycemia was determined. At day 21 of pregnancy (at term), the female rats were anesthetized and killed for maternal reproductive performance and fetal development analysis. The data were analyzed using Student-Newman-Keuls, Chi-square and Zero-inflated Poisson (ZIP) Tests (p<0.05). STZ rats presented with increased rates of pre (STZ=22.0%; ND=5.1%) and post-implantation losses (STZ=26.1%; ND=5.7%), reduced rates of fetuses with appropriate weight for gestational age (STZ=66%; ND=93%) and reduced degree of development (ossification sites). Conclusion: Mild diabetes led a negative impact on maternal reproductive performance and caused intrauterine growth restriction and impaired fetal development

Percepção do enfermeiro quanto a sua satisfação no contexto de trabalho em um hospital estadual

With the increasing competitiveness of organizations in search of customers, it is essential that the pursuit of quality becomes a prerequisite for the survival of healthcare organization, is necessary to have working conditions that encourage both personal and professional satisfaction. This study aims to investigate the perception of nurses regarding their satisfaction in the context of work in a State Hospital and contribute to the reflection on the internal customer satisfaction as an important indicator of quality of health services that interfere with quality of care. We used the qualitative method, on phenomenology, with nurses from a state hospital that had at least one year of experience in the institution. Through interviews, it was revealed that satisfaction is related to the literature and is influenced by factors such as human resources, practice nurses, Teamwork, Perception of the patient, professional recognition, physical and material resources and rewarding work, and these themes unfold quality and satisfaction both personally and for organizations

This is synthesis of the debates held during the round-table “Socioenvironmental conflicts, environmental education and social participation on environmental management”, at the V ENANPPAS (2010), which has focused on the discussion of four main themes: Socioenvironmental conflicts and the myths of social participation; Socioenvironmental conflicts and the uncertainty of conditions to environmental education immersed in problems and conflicts; Solution of Socioenvironmental conflitcts – actions mediated by instrumental rationality and emancipatory interest; Positive actions as dialogical-problematizing practice on concrete reality. From an initial provocative text, each member has brought his first contribution, followed by new questions as consequence of these speeches. The hole debate was recorded, transcripted and made a synthesis to present in this manuscript form.

Subconjunctival and topical application of recombinant tissue plasminogen activator in rabbits

To quantify fibrin degradation products after topical and subconjunctival administration of recombinant tissue plasminogen activator in rabbits. Methods: Fibrin formation was induced in the anterior chamber in 25 rabbits. Subsequently, five rabbits received an injection of r-TPA (positive control) in the anterior chamber, another 10 received a subconjunctival injection of r-TPA, and the remaining 10 received instillations of topical r-TPA. Afterwards, samples of aqueous humor were collected and semi-quantitative analysis of fibrin degradation products (FDP) was performed. Results: No statistical differences were noted between the treatment and control groups at any time point. Fibrin degradation products semi-quantification showed statistical improvement in the control group and the subconjunctival group. Conclusion: Fibrin degradation products were observed in the anterior chamber after subconjunctival administration of r-TPA. However, it was probably not sufficient to cause fibrin degradation. Topical r-TPA did not effectively absorb anterior chamber fibrin.

Delayed tooth replantation: MTA as root canal filling

MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH())2. The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and bench-dried for 60 minutes. After root canal preparation, the teeth were assigned to two groups according to root canal filling material: I, calcium hydroxide; and II, MTA. The same treatment sequence was followed for both groups: coronal seal, periodontal ligament removal, immersion of the tooth in 2% acidulated-phosphate sodium fluoride, irrigation of the socket with saline and replantation. Both groups exhibited replacement resorption, areas of ankylosis and absence of inflammatory root resorption. Statistically similar results (p > 0.05) were observed for both groups regarding replacement root resorption, but the groups differed significantly (p < 0.05) regarding the occurrence of ankylosis. MTA may be a viable clinical option for filling teeth submitted to delayed replantation, and is an acceptable option for treating replanted permanent teeth in order to prevent tooth resorption, particularly when dressing changes are not possible.
