Provedor de dados: 32
Autores: Talamantes Castorena, Saulo.
México es centro de origen, domesticación y diversificación del frijol (Phaseolus vulgaris L.) y maíz (Zea mays L.). Ambas especies han sido importantes desde la época prehispánica, y la diversidad fenotípica y genética de ambos cultivos es conservada en forma de poblaciones nativas cultivadas por los agricultores en la actualidad. En la región centro-sur de México, el sistema de producción “milpa” se practica en la actualidad, con base en una gran diversidad de poblaciones nativas de frijol común de crecimiento indeterminado cultivadas en asociación con maíz en el sistema milpa. La diversidad morfológica y genética ha sido estudiada, resultando amplia variación en formas de planta, vaina y semilla. Sin embargo, el potencial de producción, la calidad...

Volcanism and arthropods: a review
Provedor de dados: 67
Autores: Elizalde,Luciana.
Volcanic eruptions are natural disturbances that impose multiple changes in ecosystems. Arthropods are among the most diverse organisms on the planet and play key functional roles in all ecosystems. Existing information on the effects of volcanic disturbances on arthropods is scattered. The aim of this review is to fnd generalities in the responses of arthropods from terrestrial and aquatic environments to volcanism. Mainly (1) what effects do volcanic disturbances have on arthropods?, (2) what characteristics make certain species more or less susceptible to volcanic disturbances?, and (3) how do arthropod communities reassemble after a volcanic disturbance? Terrestrial and aquatic arthropods show similar responses to volcanic disturbances. Volcanism can...

Provedor de dados: 70
Autores: Jordan,Rodrigo A.; Costa,Matheus V. Da; Martins,Elton A. S.; Rosa,Maxer A.; Petrauski,Alfredo.
ABSTRACT The objective of this study is to evaluate the effect of sugarcane bagasse ash on the compressive strength and water absorption index of soil-cement bricks. The ash was sieved without chemical and/or physical treatment to reflect the use of this material in real manufacturing processes. The addition of natural ash decreased the quality of the bricks, reducing the compressive strength and increasing the water absorption index.

Autores: Mizobata,Kellian K. G. S.; Santos,Cinthia M.; Maltoni,Kátia L.; Faria,Gláucia A.; Cassiolato,Ana M. R.
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,...

Provedor de dados: 109
Autores: Chire-Fajardo,Gabriela Cristina; Valdivia-Arrunategui,Rocío Alicia; Orihuela-Rivera,Carmen Adela; Ureña- Peralta,Milber Oswaldo.
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...

Autores: Akpenpuun, Timothy Denen; Akinyemi, Banjo; Olawale, Olamide; Aladegboye, Oluwasegun Joshua; Adesina, Olalere Israel.
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...

Provedor de dados: 45
Autores: Nascimento,R.S.; Fonseca,A.B.; Feijó,M.B.S.; Franco,R.M.; Miranda,Z.B.
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...

Provedor de dados: 118
Autores: Velásquez,Patricia; Sandoval,María Ignacia; Giordano,Ady; Gómez,Miguel; Montenegro,Gloria.
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.
