| The work aimed at determination of calorific value of municipal solid waste in Enugu, Nigeria and its potential for electricity generation. Random truck sampling was used according to American Society of Test and Material (ASTM) in the collection of samples at Ugwuaji landfill site, Enugu, Nigeria and calorific value was determined using oxygen bomb calorimeter. Enugu has a present population of 882,178 and the amount of municipal solid waste generated in Enugu was estimated to be 420 tonnes daily and this resulted in waste generation rate of 0.48kg/capita/day. The average composition of the municipal solid waste was 39% putrescible, 11% paper, 21% plastics, 5% textile, and 2% metal, 3% glass and 19% others. The average moisture content Volatile... |

| ABSTRACT The effect on different three carbon source (i.e. glucose, fructose and sucrose) on production, chemical characterization and antioxidant activity of exopolysaccharide (EPS) produced by Phellinus vaninii Ljup was investigated in this study. Amongst carbon sources examined, glucose and sucrose were favorable for the mycelia growth, while the maximum EPS yield was achieved when sucrose was employed. The predominant carbohydrate compositions in EPSs identified were gluconic acid, glucose, mannose and galactose acid. Then, FT-IR spectral analysis revealed prominent characteristic groups in EPSs. EPSs molecule exist as nearly globular shape form in aqueous solution. The variation also affects antioxidant activities by investigated by using hydroxyl and... |

| Abstract Many parks in the city of São Paulo contain remnants of Atlantic Forest. Of the 30 municipal parks in the South of the city, we investigated two in this study (Santo Dias Park and Shangrilá Park) in order to survey their mosquito fauna and investigate the presence of potential bioindicators of environmental conditions and vectors of human pathogens. Mosquitoes were collected monthly between March 2011 and February 2012 using aspirators, Shannon and CDC traps for adult mosquitoes and larval dippers and suction samplers for immature forms. Sampling effort was evaluated by plotting a species accumulation curve, and total richness was estimated using the first-order jackknife. To compare the diversity between the two parks Shannon and Simpson... |

| The Brazilian Pantanal comprises a mosaic of forest and field environments harbouring a rich community of large and midsized mammals that are adapted to the annual hydrological cycle. Here we evaluated richness and composition of large and midsized mammals inhabiting forested and open habitats affected by yearly floods in the Pantanal in Cáceres from October 2009 to September 2010. We compared these communities in marshes, dry forests and riparian forests based on 640 camera-traps.nights, sights, tracks, faecal samples and interviews. We also compared results in a private land (Descalvados Farm) and in a protected area (Taiamã Ecological Station). In total, we sampled 26 large and midsized mammals, including five threatened and two near threatened species.... |

| This work aimed to study the composition and distribution of fish species at four sites along Cabeça River, an affluent of Corumbataí River, tributary of Tietê River, intending to better understand the influence of local geomorphology on the occurrence of the species along the river. Using gill nets, trawl net, cast net and sieves, five samples were taken from each site every two months. These data were analyzed from constancy of occurrence, similarity index of Jaccard, rarefaction analysis and descriptive statistical analysis of richness. 4,532 fish individuals belonging to six different orders, 17 families and 65 species were captured. Differences in composition, richness (diversity), abundance and frequency were observed at these sites along the river.... |

| This study aimed to survey the benthic macroinvertebrate fauna of a first order stream located in an agricultural area, and to assess the environmental factors involved in the spatial distribution of this community. Invertebrates were gathered in November 2007 at three sampling sites distributed along the Itiz Stream, located in Marialva municipality, Paraná State. At each site, we measured the physical and chemical variables of the water, and then took four samples, using Surber sampler. In order to evaluate the differences in density, richness, diversity and evenness, we employed an ANOVA and a DCA to summarize biotic data. The invertebrates were categorized into functional groups and the BMWP score was applied to calculate the biological integrity of... |

| Rotifers are the predominant group of zooplankton found in the majority of reservoirs, constituting more than 60% of the total zooplankton present. Being opportunistic organisms, they easily adapt to changes in environmental conditions, and it is therefore difficult to establish a constant level of composition and occurrence of a species in specific areas at specific times. In order to establish how changes in composition and predominance of a species occurs within a dynamic system, the daily variation in the total density of rotifers and that of the dominant species were studied at short intervals during a period of 20 days at Lobo (Broa) reservoir. Filinia pejleri and Keratella americana were the predominant species, making up 64.3% of the total... |

| ABSTRACT The aim of this study was to evaluate quinoa flakes and bread prepared with the pseudocereal with regard to nutritional aspects by determining chemical composition, content of tocopherols and fatty acid composition as well as to possible beneficial effects in Wistar rats given commercial feed supplemented or not with quinoa flakes and cholesterol. The following parameters were determined: weight gain, food intake, liver weight, fat in liver and lipid profile in blood and liver. The results showed that processing affected the nutritional characteristics of bread because there was a significant increase in dietary fiber content but reduction in soluble fiber. Increased fiber did not influence food intake or weight gain. Regarding fat in liver of... |

| ABSTRACT: The effect of boiling, microwaving and aluminium (Al) foil-baking on composition of intramuscular phospholipid fatty acids of Inra rabbit was evaluated. Results showed that, the proportion of polyunsaturated fatty acids (PUFA)(e.g. C18:2n-6, C20:4n-6, C20:5n-3, C22:5n-3 and C22:6n-3) and monounsaturated fatty acids (MUFA)(e.g. C18:1n-7 and C18:1n-9) of treated longissimus dorsi muscle (LD) decreased, whilst the proportion of saturated (SFA)(e.g. C16:0 and C18:0) and n-6/n-3 value increased during cooking. Among the three treatments, microwaving can do better to stop the unsaturated fatty acids (UFA) being destroyed than boiling and Al foil-baking. However, boiling treatment did more serious damage to PUFA portion. Even so, the n-6/n-3 values of... |

| This study evaluates the physical and physicochemical properties of three sugary cassava (Manihot esculenta Crantz) landraces: São Francisco Bag 3, Manicueira 62, and Castanhal Iracema. These three landraces showed high estimated productivity (≥3.93kg plant-1) and had a high sugar content (≥3.92g 100g-1 of root), making them viable for use in syrup production, especially the São Francisco Bag 3 landrace (4.76g 100g-1). The Manicueira 62 landrace had the highest starch content (4.40g 100g-1). The three sugary cassava landraces exhibited high levels of cyanide (>195mg kg-1), indicating the need for processing prior to consumption. |

| ABSTRACT: Constant monitoring of milk quality by the processing industries demands the use of methodologies that add agility and low-cost analysis, such as the use of electronic equipment based on infrared or ultrasonic spectroscopy. In the present study, quality of raw milk received by dairy farms from western region of Santa Catarina state, Brazil, was evaluated throughout two methodologies of analysis of chemical composition and compared, being that both equipment used standard procedures for calibration, considering as reference data from the classic analytical methods recommended in Brazilian legislation. Milk samples from 45 producers were analyzed for SCC, TBC and physicochemical analysis, performed at dairy’s laboratory and at the official... |
