1. STUDYING THE GRAMMAGE IN LVL PANELS GLUED WITH CASTOR OIL-BASED POLYURETHANE ADHESIVE: A POSSIBLE ALTERNATIVE TO FORMALDEHYDE RELEASING ADHESIVES.
ABSTRACT Efforts have been done in order to decrease the human dependence on petroleum materials. This idea can be applied for wood adhesives and wood products. This study proposes to evaluate laminated veneer lumber (LVL) panels of Hevea brasiliensis produced with castor oil-based polyurethane and resorcinol formaldehyde in different grammages. Six rubber t

2. Effect of soybean plant density on stem blight incidence
RESUMO Plantio direto e alta população de plantas são práticas usuais em lavouras de soja na região sul do Brasil o que tem favorecido o incremento de doenças da haste e da vagem. O objetivo deste trabalho foi avaliar o efeito de populações de plantas na incidência de seca da haste. Os experimentos foram conduzidos no município de Muitos Capões, e

3. Can leaf area in rice be defined by a mathematical model?
ABSTRACT The goal of this study was to define an empirical model to calculate the leaf area in rice from linear leaf measure in genotypes used by farmers in Brazil. Through the leaf dimensions it is possible to identify the final crop yield from the LAI. Therefore, the leaves shape is closely related to the production of photoassimilates that will be convert

4. Effect of moisture content of two paddy varieties on the physical and cooked properties of produced rice
Resumo Yasemin e Amber são as principais variedades de arroz cultivadas no Iraque. A variedade Amber é a favorita por causa de seu sabor único, enquanto a Yasemin é a mais cultivada. O objetivo do presente estudo foi determinar o teor de umidade adequado para ambas as variedades, na obtenção da melhor taxa de extração (menor quebra), brancura e quali

5. Biometrics and grain yield of sorghum varieties irrigated with salt water
RESUMO Objetivou-se com o presente estudo identificar variedades de sorgo granífero com maior potencial de crescimento e produção de grãos sob condições salinas. O estudo foi conduzido em casa de vegetação localizada na sede da Embrapa Semiárido, Petrolina, PE (9° 8’ 8,9” S 40° 18’ 33,6” O, 373 m de altitude), no ano de 2016. Adotou-se o d

6. Two independent grain-length mutants mapped to a single region on the long arm of chromosome 2 in rice
ABSTRACT Grain shape in rice is a key determinant of grain appearance, yield and market value, and thus has been widely studied. Rice mutant lines with long-grain phenotypes were previously isolated from an M2 population derived from mutagenized mature pollen grains that were treated with gamma-ray irradiation for a cultivar Ma85. To understand the genetic b

7. Critérios para avaliação da morfologia do grão de aveia para o melhoramento genético da qualidade física / Criteria to evaluate grain morphology for oat quality breeding
Apesar da morfologia do grão ser de interesse no melhoramento da aveia, critérios de amostragem e análise de grãos para a seleção da qualidade física neste cereal precisam ser determinados. Os objetivos deste trabalho foram determinar as correlações entre características morfológicas de grãos primários, secundários e terciários de aveia, com e

8. Experimental assessment of heat affected zone fracture toughness of a welded API 5L X80 steel. / Determinação experimental da tenacidade à fratura da zona termicamente afetada de junta soldada de aço API 5L X80.
This work evaluates the possible correlation between low fracture toughness (critical CTOD) and local brittle zones (LBZ) occurrences in heat affected zone (HAZ) coarse grain regions. The fracture toughness of a welded API 5L X80 steel was characterized using SE(B) specimens for CTOD determination with notches located in the HAZ. The specimen dimensions are

9. RELATIONS BETWEEN VARIABLES: SEEDS, SEEDLINGS, PLANTS, PRODUCTION AND OIL IN CASTOR BEAN / RELAÇÕES ENTRE VARIÁVEIS DE: SEMENTES, PLÂNTULAS, PLANTAS, PRODUÇÃO E ÓLEO EM MAMONEIRA
Castor bean is an oil and biodiesel source. Besides, it has a high seed yield potential in the State of Rio Grande do Sul. The objective of this work was to establish the relationship among the variables: seeds, seedlings, adult plants, grain yield and oil quality in two castor bean hybrids. The experiment was conducted at the Federal University of Santa Mar

11. Acúmulo e remobilização de NO3 - e eficiência de uso de nitrogênio em variedades tradicional e melhorada de arroz (Oryza sativa L.). / Accumulation and remobilization of NO3 - and efficiency in the use of nitrogen in traditional and improved varieties of rice (Oryza sativa L.).
The dynamics of accumulation and remobilization of NO3 -related protein content of the grains was studied in two varieties of rice, Piauí (traditional state of Maranhão) and IAC- 47 (enhanced by research institutions). The experiment was conducted in a greenhouse of UFRuralRJ in the period August 2006 to February 2007, with a completely randomized design w

12. Analysis of the structure of a hard metal: a simple method of relating properties to stereological structures
Computer simulation of the hard phase of WC-based hard metals is not common in scientific literature. This phase is formed by carbide grains embedded in a metallic matrix. In the equilibrium state, the grain has an equilateral prismatic form with beveled edges. It is nevertheless possible to model stereological aspects of this phase, using a Monte Carlo simu
