| In this study, a range of physicochemical properties (dimensions, kernel volume, mass unit, bulk and true densities, porosity, terminal velocity, static friction coefficient against different surfaces, oil content and fatty acids composition) of the Bojnordi and Fakhri cultivars of grape seeds were studied. Fatty acid composition for both cultivars of grape seeds consisted of palmitic, stearic, oleic, linoleic and linolenic acid. The values for palmitic, stearic, oleic, linoleic and linolenic acid for the Bojnordi cultivar were 9.56, 4.37, 22.87, 62.85 and 0.33% and for the Fakhri cultivar were 9.22, 4.33, 19.75, 66.40 and 0.28%, respectively. All physical properties of the grape seed cultivars were significantly affacted by the moisture content in the... |

| This work has the objective of characterizing twenty corn landraces grown in the Campos Gerais region (Paraná State) in relation to its chemical composition (moisture, ash, protein, ether extract, dietary fiber and starch) and physical properties (weight of 1000 grains, real density, flotation index, granulometry and color). In addition, also the lab scale processing of the kernels from the varieties was carried out for producing starch; starch purity was evaluated by measuring its protein contamination. Amylose contents and viscoamylograph profile were also evaluated. The results showed that the evaluated landraces have differences in chemical composition as well as in pericarp/endosperm/germ proportions and consequently it should have different... |

| O objetivo do presente trabalho foi avaliar o efeito da variação do teor de água na contração volumétrica, dimensões características e forma dos frutos de mamona durante a secagem. Foram utilizados frutos colhidos com teor de água de 2,50 (b.s.), secos à temperatura de 40°C até o teor final de 0,11 (b.s.). O tamanho dos frutos foi determinado por meio da variação do volume e a forma foi analisada pela esfericidade e circularidade. A contração volumétrica dos frutos foi determinada pela relação entre o volume em cada teor de água e o volume inicial. Com base nos resultados, concluiu-se que a forma dos frutos de mamona é influenciada pela redução do teor de água, promovendo redução da esfericidade e circularidade. As dimensões características... |

| Com base na importância do substrato na produção de mudas florestais, objetivou-se, com este trabalho, avaliar a viabilidade técnica de 13 substratos, preparados com misturas de substrato comercial à base de casca de pinus e vermiculita (SC), casca de arroz carbonizada com diferentes granulometrias [maior que 2 mm (CAC1), CAC com granulometria entre 1 ? 2 mm (CAC2), CAC com granulometria entre 0,5 ? 1 mm (CAC3), CAC com granulometria menor que 0,5 mm (CAC4)], fibra de coco (FC) e vermiculita média (VM), na produção de mudas de Eucalyptus camaldulensis, e a correlação de suas propriedades físicas e químicas com seu crescimento. Foram utilizados tubetes de 55 cm³. As mudas permaneceram 60 dias em estufa de vidro e 30 dias a pleno sol. Foram avaliadas a... |

| In avoiding damage to fruit species, the permissible falling height and permissible static pressure are of great importance. The former is important in planning harvesting and handling operations, the latter in selecting the height of transport containers. Fruits are generally transported in containers. The static and dynamic forces which then act on the fruit will cause damage if they exceed given value. The static force may be calculated from the weight of the fruit column being transported while the dynamic load is a consequence of vibration caused by transport. The permitted static load for a given fruit may be determined experimentally. The aim of this study was design of a suitable height based on the measured properties using Ross and Isaacs’s... |

| In this research the effect of moisture at three levels (57, 67, and 77 %) on the physical properties of the Barkat bean variety including, including dimensions, geometric mean diameter, volume, sphericity index and the surface area was determined. And the influence of different moisture content levels (67,57 and 77%), in two loading orientation (longitudinal and transverse) and three loading speed (8,6 and 10 mm min-1) on the mechanical properties of the maximum deformation, rupture force, rupture energy, toughness and the power to break the broad bean was investigated. It was observed in the mechanical properties that moisture changes and loading speed were affective at 1% on rupture force, rupture energy, and toughness. Loading orientation was affective... |

| The physical and mechanical properties of agricultural products have an effective role in determining the quality of the products, reducing the potential damage caused by transportation and eventually designing the equipment used in the processing of the products. In this study, some physical and mechanical properties of snake melon were measured under standard conditions. Physical properties included length, width, thickness; mean diameter (geometric and arithmetic), sphericity, surface area, aspect ratio, mass, volume and density. The mechanical properties of the samples and their lengths were measured under the conditions of pressure (bruise), bending (break) and cutting of the snake melons in halves using a Zwick/Roell Instron testing machine based on... |

| Used Azivash seed in the research has been provided in summer 2013. The samples were cleaned and separated manually and residuals and broken seeds were taken apart it and healthy seed was provided for testing. Then diameter, area of image, and round coefficient, were calculated using image processing application. Mass of 1000 seeds, mass density, real density and porosity percentage, static friction coefficient, repose angle in two modes of fullness and emptiness were measured. Liquid replacement method has been used to calculate density and volume of the seeds. The results showed that a positive relationship between physical properties of Azivash seed including geometric properties (diameter, volume), gravity properties (weight of 1000 seeds, real density... |
