Produção de grês porcelanato a partir de matérias-primas do estado da Bahia

The State Bahia, Brazil, presents different geological sites it with a very expressive variety minerals. It is situated among the very important States which produces minerals for industries, such as pointed aggregate, ornamentals stones and ceramics raw materials. Nowadays only four companies producting ceramics tiles. Porcelainized stoneware tiles is one of the noblest ceramics, depicting low water absorption (typically below of 0,5%), in addition to excellent staining resistance and mechanical strength. The present work aims at investigating the potential of local raw materials for the production of porcelainized stoneware tiles. For this purpose, these materials were characterized by X-ray fluorescence, X-ray diffraction, particle size analysis, thermal gravimetric analysis, thermal differential analysis and dilatometric analysis. Admixtures containing different compositions were prepared and fired at four temperatures, 1100 ºC, 1150 ºC, 1200 ºC and 1250 ºC with isotherm for 60 minute and heathing rate of 5 oC/min. After firing the samples, they were characterized by water absorption tests, linear retraction, analysis, apparent porosity, apparent specific mass, flexural strength, and microstructural analysis by X-ray diffraction and scanning electron microscopy . The results revealed three ceramics with porcelainized stoneware tiles characteristics and porcelain tile will be produce from raw materials originated in the State of Bahia

A melancolia nas crônicas de Maria Judite de Carvalho

Maria Judite de Carvalho began his literature in 1949 in journals of Lusitanian capital. Until his death, which occurred in 1998, published more a thousand texts, most of them have never been extracted from their support original, the newspaper, making them unknown to the public today. In order to rescue of this precious material chosen as the literary corpus of Search the chronicles published in the Diário de Lisboa, periodic where the writer published the largest number of texts in the section Rectângulos da Vida, 395 (three hundred and ninety-five) chronic for five consecutive years (1968-1972). Looking at these texts I realized that she inserted into her narrative the changes occurred in the twentieth century, in Portugal, capturing the moment of breaking with traditional models and introducing new paradigms imposed by modernity. What happens in this period is an extremely fast and deep change of values and customs with which the Portuguese society faces and experiences with a certain uneasiness. Given this unstable scenario, Maria Judite expresses, through her ironic and critical narrative, the portrait of the Portuguese people and their behavior full of anguish and sorrows that are revealed through the gloom. After a thorough reading of his texts I found that this was the guiding element of juditiana writing. It is presented in the chronicles in many respects they were privileged during the five years of publications they are loneliness, abandonment, death, isolation of individuals who feel increasingly powerless in the face of changes experienced as a consequence of this state and present is melancholy all the time. This is a photograph of Maria Judite de Carvalho on Portuguese society told in her chronicles as I saw this survey.

O teatro de Deus: a construção do espaço sagrado de juazeiro a partir de narrativas femininas (Ceará, 1889-1898)

In this work, we discuss the construction of Juazeiro in the state of Ceará -, as a sacred space from the analysis of the testimonies of nine religious women called beatas in an Episcopal process in the late nineteenth century. This process was initiated in 1891 to investigate the occurrence of an Eucharistic miracle with beata Maria Magdalena do Espírito Santo de Araújo. We show that the punitive strategies of the Diocese eventually caused a reordering of pilgrimages to Juazeiro which until 1894 worshipped the Precious Blood and that after the condemnation of the phenomena by the Holy See are rearranged around the figure of Father Cicero Romão Batista, under the pretext of worshipping the priest himself and also Nossa Senhora das Dores, currently the patron saint of the city of Juazeiro do Norte.

Otimização no uso de martelos e bigornas para quebrar sementes por macacos prego (Cebus flavius e C. libidinosus) no Bioma Caatinga

Recently, capuchin monkeys (Cebus spp.) inhabitants of dry environments and with restriction of fleshy fruits, have been the subject of several studies regarding the use of instruments. During behaviour of using stones to crack open nuts there is evidence of selection of more effective hammers, as well as selection of anvils related to reducing the risk of predation. The aim of this study was to determine whether two groups of capuchin monkeys (C.flavius and and C.libidinosus) inhabitants of the Caatinga of Rio Grande do Norte make choice of hammers and anvils. The record of weight and location of stones indicated active choices of with what (choice of hammers) and where (selection of anvils) to crack open encapsulated seeds. The choice of hammers to break nuts depended on the type and degree of ripeness seed. Thus, smaller seeds were smashed with lighter hammers and larger seeds with heavier hammers. Still, C. flavius was the only species that presented a refinement in the choice of hammers that depended on the ripeness of seeds. For both species of capuchin monkeys studied, the nut-crack sites were not spread in accordance with the spatial distribution of seed-producing species, suggesting that the capuchin monkeys promote active choice of anvils. Thus, in environments with more escape routes through the trees, the nut-crack sites were found further apart than in regions that had less chance of escape through the trees. Also, there was a difference in the spacing of the anvils to depend on the type of seed: sites used to crack larger and more caloric seeds were found farther apart than the sites used to crack smaller and less caloric seeds, suggesting a pattern of avoiding direct competition. We conclude that the capuchin monkeys maximize energy savings and reduced risk of predation and the costs of food competition during the behaviour of using stones to crack open nuts

Metabolic assessment in patients with urinary lithiasis

INTRODUCTION: Metabolic investigation in patients with urinary lithiasis is very important for preventing recurrence of disease. The objective of this work was to diagnose and to determine the prevalence of metabolic disorders, to assess the quality of the water consumed and volume of diuresis as potential risk factors for this pathology. PATIENTS and METHODS: We studied 182 patients older than 12 years. We included patients with history and/or imaging tests confirming at least 2 stones, with creatinine clearance > 60 mL/min and negative urine culture. The protocol consisted in the collection of 2, 24-hour urine samples, for dosing Ca, P, uric acid, Na, K, Mg, Ox and Ci, glycemia and serum levels of Ca, P, Uric acid, Na, K, Cl, Mg, U and Cr, urinary pH and urinary acidification test. RESULTS: 158 patients fulfilled the inclusion criteria. Among these, 151 (95.5%) presented metabolic changes, with 94 (62.2%) presenting isolated metabolic change and 57 (37.8%) had mixed changes. The main disorders detected were hypercalciuria (74%), hypocitraturia (37.3%), hyperoxaluria (24.1%), hypomagnesuria (21%), hyperuricosuria (20.2%), primary hyperparathyroidism (1.8%) secondary hyperparathyroidism (0.6%) and renal tubular acidosis (0.6). CONCLUSION: Metabolic change was diagnosed in 95.5% of patients. These results warrant the metabolic study and follow-up in patients with recurrent lithiasis in order to decrease the recurrence rate through specific treatments, modification in alimentary and behavioral habits.

Desenvolvimento territorial e a política nacional de água em Moçambique: o caso do distrito de Chibuto

The development has been a phenomenon in constant discussion today, whose fundamental importance should be to promote the welfare of humanity. Thus, the development becomes an element that adds political, economic, social and environmental values . In Mozambique the development model adopted by the State prioritizes the economic dimension, in this case favoring the growth of capitalist structure production. Thus , the basic conditions for human survival still leaves much to be desired and the Mozambican population in general and the district of Chibuto , in particular , continue to face several difficulties to have access to such conditions, and the lack of potable water is a that most of the problems afflicting this population . The water was always a factor related to the socio-economic development of the population, where great civilizations and major economic marks were always influenced by water availability, and today this feature is present in all sectors of production. In Mozambique, much effort has been made by the government, national and international organizations to enhance and guarantee the supply of potable and drinking water, and despite all this effort, most of the population does not have access to this precious resource. In this sense, this work presents an analysis of the effects of the National Water Policy in the study area, analyzes the shortage of potable water in the district of Chibuto, discusses the design and development contained in the official discourse of the state and, opposes the idea of human development. For such issues that help to understand the phenomenon under study, such as territory, public policy and criticism of hegemonic conception of development are addressed. To make the desired approach, we performed a characterization of the District of Chibuto, addressing the issue of poverty, with a brief discussion of this concept, from different approaches, and analyze the impact of the PARPA (Action Plan for the Reduction of Absolute Poverty) in fighting poverty in Mozambique, and became a description of the scenario of poverty and vulnerability in Chibuto district with the construction of Territorial Human Development Index. Research also brings up a discussion about territory and technicization which describes the senary of the water supply system in the District and territorial dynamics of Chibuto, from the analysis and description of existing structures and other technical objects that structure the territory under study. Thus, it was found that the development should be summarized in the satisfaction of human needs, and should be the cornerstone of the new type of development that is intended for the purpose of triggering urgently actions to overcome or combat bleak misery suffered by the majority of inhabitants of the District of Chibuto

The role of salt abuse on risk for hypercalciuria

Background: Elevated sodium excretion in urine resulting from excessive sodium intake can lead to hypercalciuria and contribute to the formation of urinary stones. The aim of this study was to evaluate salt intake in patients with urinary lithiasis and idiopathic hypercalciuria (IH).Methods: Between August 2007 and June 2008, 105 lithiasic patients were distributed into 2 groups: Group 1 (n = 55): patients with IH (urinary calcium excretion > 250 mg in women and 300 mg in men with normal serum calcium); Group 2 (n = 50): normocalciuric patients (NC). Inclusion criteria were: age over 18 years, normal renal function (creatinine clearance >= 60 ml/min), absent proteinuria and negative urinary culture. Pregnant women, patients with intestinal pathologies, chronic diarrhea or using corticoids were excluded. The protocol of metabolic investigation was based on non-consecutive collection of two 24-hour samples for dosages of: calcium, sodium, uric acid, citrate, oxalate, magnesium and urinary volume. Food intake was evaluated by the three-day dietary record quantitative method, and the Body Mass Index (BMI) was calculated and classified according to the World Health Organization (WHO). Sodium intake was evaluated based on 24-hour urinary sodium excretion.Results: The distribution in both groups as regards mean age (42.11 +/- 10.61 vs. 46.14 +/- 11.52), weight (77.14 +/- 16.03 vs. 75.99 +/- 15.80), height (1.64 +/- 0.10 vs. 1.64 +/- plusorminus 0.08) and BMI (28.78 +/- 5.81 vs. 28.07 +/- 5.27) was homogeneous. Urinary excretion of calcium (433.33 +/- 141.92 vs. 188.93 +/- 53.09), sodium (280.08 +/- 100.94 vs. 200.44.93 +/- 65.81), uric acid (880.63 +/- 281.50 vs. 646.74 +/- 182.76) and magnesium (88.78 +/- 37.53 vs. 64.34 +/- 31.84) was significantly higher in the IH group (p < 0.05). There was no statistical difference in calcium intake between the groups, and there was significantly higher salt intake in patients with IH than in NC.Conclusions: This study showed that salt intake was higher in patients with IH as compared to NC.

POST-MORTEM LESIONS of UROLITHIASIS IN A LESSER SEED FINCH (Sporophila angolensis).

Urolithiasis is a disease that despite being a commonly observed problem in veterinary practice is uncommon in birds. Such disease was not reported in passeriforms to date. Accordingly, the aim of the present article is to describe a case of urolithiasis in an adult female lesser seed finch (Sporophila angolensis) pet bird which presented abdominal distension, respiratory distress, and apathy prior to death. The bird had history of being fed with a diet rich in protein. After the bird death, a necropsy was conducted in order to determine the cause of death. At necropsy, accentuated ascites, hydropericardium, and ureteral stones in the left ureter could be grossly observed. Additional tests related with viral and bacterial microbiological testing and with the determination of calculi composition could not be performed since the owner did not consent with the procedures because of the cost. Since the bird was fed on a high protein diet, a relationship between the ureteroliths and dietary imbalance was suggested with participation of protein in calculi development by providing the organic nuclei. Additionally, we conclude that the presence of calculi in the ureter resulted in urinary flow blockage, ascites, and consequent acute respiratory failure due to filling of air sacs with liquid.

Efeito da desinfecção por aerossóis sobre a capacidade de umedecimento de moldes de poliéter por gesso tipo IV

A desinfecção de todo e qualquer molde obtido é medida de biossegurança obrigatória na atividade clínica. Tão importante quanto a desinfecção é a seleção do método e da solução desinfetante a ser utilizada para cada material de moldagem. É imperativo que a capacidade de reprodução de detalhes, a estabilidade dimensional e o grau de umedecimento (ou molhabilidade) não sejam criticamente afetados. O propósito deste trabalho foi avaliar o grau de umedecimento de uma marca comercial de poliéter (Impregum F) por três diferentes marcas comerciais de gesso tipo IV (Herostone, Durone e Polirock), após sua desinfecção por aerossóis de hipoclorito de sódio 1% (líquido de Milton) ou glutaraldeído 2% (Glutalabor II). Foram confeccionados 45 moldes de poliéter, os quais, em grupos de 15, receberam aerossóis de água (Grupo Controle), Líquido de Milton ou Glutalabor II. em seguida, sobre a superfície dos moldes foram confeccionados modelos de gesso tipo IV, em número de 5 para cada marca de gesso. Após seu seccionamento mediano e preparo da superfície de corte, os modelos foram levados ao microscópio Carl Zeiss para leitura do ângulo de contato. Os resultados obtidos permitiram concluir que: a) a capacidade de umedecimento do poliéter por diferentes marcas comerciais de gesso tipo IV variou para os gessos estudados; b) o gesso Durone adaptou-se melhor aos moldes de poliéter do que os gessos Herostone e Polirock; c) a desinfecção dos moldes com aerossóis de hipoclorito de sódio 1% (líquido de Milton) ou glutaraldeído 2% (Glutalabor) não afetou a adaptação entre os gessos e o poliéter.

Water Buffalo Genome Science Comes of Age

The water buffalo is vital to the lives of small farmers and to the economy of many countries worldwide. Not only are they draught animals, but they are also a source of meat, horns, skin and particularly the rich and precious milk that may be converted to creams, butter, yogurt and many cheeses. Genome analysis of water buffalo has advanced significantly in recent years. This review focuses on currently available genome resources in water buffalo in terms of cytogenetic characterization, whole genome mapping and next generation sequencing. No doubt, these resources indicate that genome science comes of age in the species and will provide knowledge and technologies to help optimize production potential, reproduction efficiency, product quality, nutritional value and resistance to diseases. As water buffalo and domestic cattle, both members of the Bovidae family, are closely related, the vast amount of cattle genetic/genomic resources might serve as shortcuts for the buffalo community to further advance genome science and biotechnologies in the species.
