| In this study, some important physical and mechanical properties of the hawthorn and the effect of moisture on them were investigated. The effect of moisture at two levels (64.01% and 70.1%, w.b.) on the geometric dimensions (length, width, thickness, arithmetic mean diameter, geometric mean diameter, degree of sphericity, surface area, projected area, criteria projected area, mass, volume and the apparent), true density, porosity, coefficient of static friction and coefficient of rolling on three levels (wood, glass and galvanized) and mechanical properties obtained by impact testing machine using a randomized factorial design was evaluated by software SPSS18. Results indicate that moisture has an effect on the physical properties of the hawthorn. The... |

| Surface coal mining causes an intense topographic and hydrologic change in the area with suppression of local vegetation, degrading the environment. One main problem presented by the rehabilitated soil refers to physical disruption of the soil, which delays the regrowth of plant species in the mining area. The objective of this study was to evaluate the influence of four grass species in the retrieval of the rehabilitated soil's physical properties at a recovered coal mine area in Candiota, Rio Grande do Sul State, southern Brazil. With the data an ANOVA was performed and treatments means were compared using Tukey test (p ≤0.05). The treatments were: T1-Hemarthria altissima; T2-Paspalum notatum; T3-Cynodon dactylon; T4-Urochloa brizantha; a rehabilitated... |

| 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... |

| 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... |

| Honey is a naturally sweet and viscous fluid produced by honeybees {Apis mellifera) from the néctar of flowers that, by definition, does not include any other substances. The objectives of this work were to characterize Pakistani honey, physically and chemically in relation to international standards, and to study the effects of adulteration with sugar syrup on the physical properties of honey. For this purpose, 200 honey samples obtained from 15 different locations in Pakistán, ranging from desert to hilly áreas, were collected in 2005-2006. Samples were prepared by the acid digestión method. Physical properties, conductance, surface tensión, and pH were determined using digital instruments. The most abundant minerals found in Pakistani honey samples were... |
