1. REGULATED AIR POLLUTANT EMISSIONS FROM HIGHER EMITTERS STATIONARY SOURCES IN BELO HORIZONTE, MINAS GERAIS, BRAZIL
Abstract Belo Horizonte, capital of Minas Gerais state, is a highly urbanized city located in the third largest metropolitan area of Brazil, being one of the most important cities in the country. There are several potential air pollutant emission sources in the studied area, such as industry and the vehicular fleet (1,669,884 vehicles in 2015). These can aff

2. Assessing geologic model uncertainty - a case study comparing methods
Abstract Evaluating mineral resources requires the prior delimitation of geologically homogeneous stationary domains. The knowledge about the ore genesis and geological processes involved are translated into three dimensional models, essential for planning the production and decision-making. The mineral industry usually considers grade uncertainty for resour

3. Evaluation of short-chain-length polyhydroxyalkanoate accumulation in Bacillus aryabhattai
Abstract This study was focused on the polyhydroxybutyrate (PHB) accumulation property of Bacillus aryabhattai isolated from environment. Twenty-four polyhydroxyalkanoate (PHA) producers were screened out from sixty-two environmental bacterial isolates based on Sudan Black B colony staining. Based on their PHA accumulation property, six promising isolates we

4. Low-intensity red and infrared laser effects at high fluences on Escherichia coli cultures
Semiconductor laser devices are readily available and practical radiation sources providing wavelength tenability and high monochromaticity. Low-intensity red and near-infrared lasers are considered safe for use in clinical applications. However, adverse effects can occur via free radical generation, and the biological effects of these lasers from unusually

5. Influence of multiple bioprocess parameters on production of lipase from Pseudomonas sp. BWS-5
The aim of the present work was to study the influence of multiple bioprocess parameters for the maximum production of lipase from Pseudomonas sp. BWS-5. The culture reached the stationary phase of growth after 36h of incubation when the maximum lipase production was obtained at flask level. The different media components such as carbon sources, nitrogen sou

6. Estudio del impacto en la calidad del aire de las fuentes puntuales en la ciudad de pinar del Río
A study of the impact of stationary sources on air quality on the city of Pinar del Rio, Cuba, using the modeling system MM5-CALMET-CALPUFF was made. The dispersion of SO2, NOx, CO, PM10 and PM25 emitted from 21 sources during 15 days is simulated by the model. This period is representative of the rainy season in Cuba (Summer). The of SO4(2-) and NO3- wet de

7. Diauxic growth of Geotrichum candidum and Penicillium camembertii on amino acids and glucose
The purpose of this work was to examine physiological differences between the yeast Geotrichum candidum and the mould Penicillium camembertii, organisms involved in the industrial process of cheese ripening. Three groups of amino acids had previously been characterized, based on their carbon assimilation and dissimilation by the two fungal species. For both

8. FormulaÃÃo MatemÃtica para CÃlculo de VariaÃÃo de ConcentraÃÃo em Escoamento EstacionÃrio / Mathematical Formulation For The Calculation Of Changes Of Concentration In Stationary Flow.
The main aim of this research is to evaluate a variation of concentration between the affluent and effluent in a biophysical or physicochemical system. The theoretical system of references used here was based upon a differential equation of steady flow, involving a chemical kinetics and a longitudinal dispersion, in which there is a number of sufficiently lo

9. Screening and optimization of pectin lyase and polygalacturonase activity from ginseng pathogen Cylindrocarpon Destructans
Cylindrocarpon destructans isolated from ginseng field was found to produce pectinolytic enzymes. A Taguchi's orthogonal array experimental design was applied to optimize the preliminary production of polygalacturonase (PG) and pectin lyase (PL) using submerged culture condition. This method was applied to evaluate the significant parameters for the producti

11. Assay of antioxidant potential of two Aspergillus isolates by different methods under various physio-chemical conditions
The objective of this work was to screen fungi isolated from soil of different areas of Punjab, India for antioxidant activity by dot blot assay and around 45% of fungal isolates demonstrated antioxidant potential. Two selected strains of Aspergillus spp (Aspergillus PR78 and Aspergillus PR66) showing quantitatively best antioxidant activity by DPPH assay we

12. Vacuum energies and multipole interactions
In this paper, we present a quantum-field-theoretical description of the interaction between stationary and localized external sources linearly coupled to bosonic fields (specifically, we study models with a scalar and the Maxwell field). We consider external sources that simulate not only point charges but also higher-multipole distributions along D-dimensi
