| Biomass furnace ash (BFA) generated from drying of grains in mechanical dryers were blended with cement in varying ratio of 1:4, 1:5, 1:6, 1:7 and 1:8 by volume. Each composition was cured in an ambient condition for 7, 14 and 28 days and determined their properties such as density, porosity, compressive strength and thermal shock resistance. Cold crushing strength increased with increasing cement content and curing time. Likewise, density increased with increasing cement content and curing time while porosity showed the other way. All the sample compositions exceeded 30 cycles without any crack when subjected to thermal shock resistant cycles of heating and cooling using a firing temperature of 1000oC in an electric muffle furnace. |

| Abstract: The quality of the main chocolates marketed in Peru was determined. The physical aspect: color (C *, H *, IB), hardness and particle size, as well as physicochemical: water activity (aw), moisture, fat and ash, correlating with the declaration of ingredients presented in the packaging. We evaluated 30 experimental units of chocolates (imported, domestic, dark chocolate and milk) by experimental methods, randomly acquired from different establishments. The difference between color and hardness by origin was attributed to the dairy component. Dark chocolate had lower values of color components (8.75 ± 0.94 C *, 7.60 ± 4.71 H * and 28.46 ± 0.86 IB) than milk constituents (15.04 ± 2.78 C, 34.59 ± 7.46 H * and 34.55 ± 2.87 IB) and in hardness values... |

| Abstract This research was carried out to evaluate centesimal [dry matter (DM), ash, and crude contents of proteins (CP), fats (CFt) and fiber (CFb)] and mineral composition (Ca, Mg, N, P, K, Fe, Zn, Cu and Mn) of peel and flesh tissues of feijoa fruit (cultivars Alcântara, Mattos, Helena and Nonante, and accession 2316). The genotypes had, in the flesh, DM of 12.10-15.40%, ash of 0.33-0.40%, CP of 0.95-1.45%, CFt of 0.56-1.72%, and CFb of 1.39-2.43%, and in the peel DM of 12.8-17.27%, ash of 0.30-1.49%, CP of 0.56-0.88%, CFt of 0.57-0.90%, and CFb of 2.54-3.98%. The contents of Ca, Mg, K, N and P in the peel were 96-116, 20-30, 1588-3635, 1096-1643 and 68-83 mg kg-1 FW, respectively, and in the flesh were 56-92, 17-29, 1358-2917, 2017-3384 and 255-374 mg... |

| Abstract This experiment was conducted to evaluate the effect of in-ovo ascorbic acid (AA) injection on the bone development of broilers submitted to heat stress during incubation and rearing. One thousand (1,000) Cobb(r)fertile broiler eggs were randomly distributed according to the weight into five incubators, with 200 eggs per incubator. The incubation treatments were: eggs not injected with AA and incubated at 37.5°C; eggs not injected with AA and incubated at 39°C; and eggs injected with 6 µg AA/100 µL water prior to incubation and incubated at 39ºC. The hatched birds were reared at three different house temperatures: cold, thermoneutral, or and hot. The high incubation temperature negatively influenced broilers' bone characteristics. The femur of the... |

| The objective of this work was to evaluate elephant grass (Pennisetum purpureum Schum.) genotypes for bioenergy production by direct biomass combustion. Five elephant grass genotypes grown in two different soil types, both of low fertility, were evaluated. The experiment was carried out at Embrapa Agrobiologia field station in Seropédica, RJ, Brazil. The design was in randomized complete blocks, with split plots and four replicates. The genotypes studied were Cameroon, Bag 02, Gramafante, Roxo and CNPGL F06-3. Evaluations were made for biomass production, total biomass nitrogen, biomass nitrogen from biological fixation, carbon/nitrogen and stem/leaf ratios, and contents of fiber, lignin, cellulose and ash. The dry matter yields ranged from 45 to 67 Mg... |

| ABSTRACT In areas where soil surface horizons were removed, the main edaphic problems are reduced amounts of organic matter and nutrients. Revegetation, especially with native species, has been indicated to recover these areas. Under this perspective, the present research has been developed to evaluate the contribution of organic and agro-industrial residues, as conditioners of soil fertility and their effects on initial growth of 'Jatobá-do-cerrado' seedlings. The treatments consisted of 4 agro-industrial residue doses (0, 15, 30 and 45 Mg ha-1) and 4 organic residue doses (0, 8, 16 and 32 Mg ha-1), with 16 treatments and 10 replicates. After 8 months of development, the soil was evaluated for phosphorus, organic matter, hydrogen potential, potassium,... |

| This study looks at the effect of cement replacement with locust bean pod ash (LBPA) as a supplementary cementitious material on compressive strength of mortars. The fresh properties (workability, initial and final setting times), compressive strength at 7, 14, 21 and 28 days and microstructural analysis (SEM, EDS and XRD) were evaluated. LBPA were considered at replacement levels of 0, 10, 15, 20 and 30% of cement mass for preparation of the mortar samples. Workability of the cement mortars reduced as the content of LBPA increases while initial and final setting times increased in relation to increase in LBPA content in the matrix. An increase of about 79% in compressive strength at 7 days, 100% at 14 days, 147% at 21 days and 136% at 28 days were... |

| Peumus boldus is an endemic Chilean tree whose edible fruit lack a history of scientific research. The aim of this study was to determine its nutritional composition (moisture, ash, crude fiber, proteins, carbohydrates and lipids) and polyphenolic content (total phenolic content, HPLC-DAD, HPLC-MS/MS analysis) at different stages of development. The results show that the fruit decreased in ash, crude fiber and total phenolic content throughout its development, while its carbohydrate and protein content increased. An increase in phenolic molecules such as catechin and epicatechin was also observed. This is the first report on the nutritional composition and phenolic content of Peumus boldus Mol. fruits. |

| ABSTRACT The aim of this study was to evaluate the physicochemical characteristics of three formulations of smoked cooked linguiças, only differing in the lean meat used: (Formula 1 ― 100% ostrich meat; Formula 2 ― 50% ostrich meat + 50% pork; and Formula 3 ― 50% ostrich meat + 50% chicken), elaborated with ostrich meat trimmings. The formulas showed slightly higher moisture content (62.00-64.41%) than the maximum allowed in the legislation for cooked linguiças (60%) (Brasil, 2000). However, their protein content (19.99-22.14%) was at least 42% higher than the minimum required level (14%); the fat content (11.82-14.25%) was less than half the maximum permitted level (35%) in the same legislation, and at least 45% less than three well-known smoked cooked... |
