Rochas ornamentais e de revestimento do sudoeste do estado do mato grosso

Geological, petrographical, chemicals and technological studies of rocks of the southwest region of Mato Grosso State, Brazil have the purpose of qualification and application of these rocks as dimension stones. The first objective is to enlarge the offering of new esthetic varieties that show a standardization of technologic patterns, adequate characterization and classification assuring the correct specification of the rocks in relation to the use as dimension stones. Ten rock types are recognized for dimension stones, including granites, diabases, gneisses and amphibolites grouped by its colors in red, grey and black types and showing economic potential of plowing. The results obtained in the technological essays show that the rock parameters are sited inside the standard limits established by technical rules and obey satisfactorily the limit values fixed for granites in internal and external covering uses.

Investigação tecnológica de arenitos silicificados da Formação Botucatu (ne do Paraná) para uso como rocha de revestimento

For many years the silicified sandstone associated of the Botucatu Formation has been the target of interest to researchers and miners, either for understanding the genesis of silicification or for your use as dimension stone and covering on the building industry. If in the first there are several articles available in the geological literature the second there are only technical data marketing available. In the northeast portion of the Paraná State and southwest of the São Paulo State these rocks are mined and traded as covering stones. Not much is known about their intrinsic characteristics and technological properties. To improve the knowledge of the technological behavior of these materials, samples from a quarry from Ribeirao Claro region were petrographically and physically characterized according to the standards established by the Brazilian Association of Technical Standards to dimension stones. Therefore, two bulk samples of silicified sandstone of the Ribeirão Claro/PR region were studied and characterized following the norms established by Brazilian Association of Technical Standards for dimension stones. The results obtained in the petrographical and technological studies are presented and indicated that, in general, the technological performance presented by sandstone studied induces limitations of use as covering materials, mainly horizontally as pavements, door stone and step ladder.

iSPD: An iconic-based modeling simulator for distributed grids

Simulation of large and complex systems, such as computing grids, is a difficult task. Current simulators, despite providing accurate results, are significantly hard to use. They usually demand a strong knowledge of programming, what is not a standard pattern in today's users of grids and high performance computing. The need for computer expertise prevents these users from simulating how the environment will respond to their applications, what may imply in large loss of efficiency, wasting precious computational resources. In this paper we introduce iSPD, iconic Simulator of Parallel and Distributed Systems, which is a simulator where grid models are produced through an iconic interface. We describe the simulator and its intermediate model languages. Results presented here provide an insight in its easy-of-use and accuracy.

Tropical influence in oriental gardens in Brazil

In the contemporary landscaping, among the gardening styles, the Japanese Garden plays very important rule and influence. The Japanese Garden has originated in China-the cradle of gardening culture; and Korea. Their vegetable elements, architectural features and fauna are characteristic, due to use of stones, water, bridges, stoned lamp, bonsai, carps and bamboo (Prunus serrulata, Camellia japonica, Ophiopogon japonicas) and many others. In Brazil, the Japanese Garden has massive influence, the presence of native elements typically tropical is very noticeable. This influence can be observed both in architecture, vegetation and fauna. Thus, this study aimed to identify and analyze the tropical elements in Japanese Gardens in cities such as São Paulo. Japanese Gardens in Brazil were chosen from the following cities: Sao Paulo State, Garça, Jaboticabal and Ribeirão Preto. It was observed, mostly in the presence of different palms species, plants of the Zingiberales order, Alpinia purpurata and styled architectural elements such as lakes. Some elements were able to apply the philosophy of the Japanese Garden, other not.

Ocorrência de cristais em plantas medicinais utilizadas no tratamento da nefrolitíase: Paradoxo?

Nephrolithiasis (kidney stones) can be seen as a common clinical condition responsible for substantial economic, social and psychological costs, due to its high morbidity, especially since it affects adults in their productive phase. Its development in the urinary tract is a complex and multifactorial process. The majority of kidney stones are made of calcium oxalate. A lot of plants are used to treat nephrolithiasis and they often exhibit calcium oxalate crystals in the parts that are employed for this medicinal purpose, representing a possible risk. In this light, we performed a literature review via the databases Scielo, PubMed and Medline and found 28 articles reporting the traditional use of plants in the treatment of nephrolithiasis. The occurrence of calcium oxalate crystals was indicated in 19 species. We argue that the use of these plants could give rise to adverse effects in people who are prone to form calcium oxalate stones in the kidney.

Composition and quantification of the anthropogenic and natural fractions of wastes collected from the stormwater drainage system for discussions about the waste management and people behavior

A study was made of the composition of wastes collected from the pipes of the stormwater drainage system of Sorocaba, SP, Brazil (600 thousand inhabitants). A total of 10 samples weighing at least 100 kg each were sorted into 19 items to determine the fraction that can be considered natural (earth/sand, stones, organic matter, and water, the latter determined after oven-drying the samples) and the anthropogenic fraction (the remaining 15 items, especially construction and demolition wastes and packaging). Soil/sand was found to be the main item collected (52.5 % dry weight), followed by the water soaked into the waste (24.3 %), which meant that all the other wastes were saturated in mud, whose contents varied from 6.4 % (glass) to 87.2 % (metalized plastics packaging). In general, 83 % of the collected wastes can be classified as natural, but the remaining 17 % represent 2,000 kg of the most varied types of wastes discarded improperly every day on the streets of the city. This is an alarming amount of wastes that may clog parts of the drainage systems, causing troubles for all the population (like flooding) and must be strongly considered in municipal solid wastes management and in environmental education programs. © 2013 Springer Science+Business Media Dordrecht.
