| Selected engineering properties (physical and mechanical) of dry bean under non-irrigation and drip-irrigation were determined and compared. These properties are necessary for the design of equipments for harvesting, processing, transporting, estimating loads in storage structures for crops and flow problems in silos such as arching, ratholing, irregular flow and segregation. Some engineering characteristics such as: average length, width, thickness, the geometric mean diameter, sphericity, surface area, volume, thousand grain mass (M1000), bulk and true densities, porosity, angle of internal friction, static coefficient of friction, Poisson ratio and pressure ratio were studied. The highest average values for physical properties were recorded at... |

| The mechanical properties for the threshing mechanism design, distance setting and the size of thrasher for better threshing and less damage to the seeds were used. In this study the mechanical properties of unbroken pods of canola were investigated including failure force, failure deformation, failure strain, failure energy, toughness, and modulus of elasticity planted in three canola varieties in the fields of Aliabad city in Iran including Hyola 50, 401, and 420 at the three times of sampling in pre-harvest, harvest and post-harvest in two direction of loading (in the direction of small and medium diameter). Canola varieties had different moisture levels at the same time, and this moisture was measured as a sub factor. The results show that moisture... |

| Study to determine physical and mechanical properties of seeds at different moisture content is necessary for the design of equipment to handle, process, transport, and store the same. The physical properties of coriander seeds have been evaluated as a function of seed moisture content, varying from 8% to 16% (w.b.). In the moisture 11.2%, seeds major, minor and medium dimensions were 5.062, 3.27, and 3.404 mm respectively. Sphericity of the seeds was found to be 0.757 with a surface area of 46.167 mm2. One thousand seed weight increased linearly from 8.89 to 9.826 g when the moisture content increases from 8.5 to 15.89% (w.b.). The true density of coriander seeds decreased when the moisture content increased 8.73 to 12%, from this point, true density... |

In this study, some physical properties of tomato (Solanum lycopersicum) fruits were determined and their mutual relationships were studied. Dimensions (major diameter, minor diameter, and length), mass, volume, fresh and dry matter weight, as well as rupture point under uniaxial loading were measured. Other properties; including Poisson's ratio, modulus of elasticity, energy for rupture, density, arithmetic mean diameter, geometric mean diameter, diameter of equivalent volume sphere, and sphericity were calculated accordingly. Statistical analysis of the data indicated significant correlations between the rupture force and fresh weight, volume, dry weight,... |

| The large cardamom is one of the most important spice crops grown in Himalayan region of Sikkim, India. The capsules of the harvested large cardamom are dried before consumption. The paper presents the physical properties of freshly harvested and dried large cardamom capsules. The geometrical mean diameter, sphericity, bulk density and mean values of angle of repose of the freshly harvested large cardamom capsules were observed to be 18.53±1.73 mm, 0.76, 332.21±14.24 kg m-3 and 28.74±4.04°, respectively. Whereas for dried large cardamom capsules the values were found to be 11.113±0.92 mm, 0.56, 393.109±9.622 kg m-3 and 29.84±2.93°, respectively.

| Knowing the physical and mechanical properties is very important for automating the activities associated with the date pit. The objective of this study was to determine physical and mechanical properties of date pit of Mazafati cultivar as a function of moisture content. The physical properties of the pits were determined in the moisture content range of 7% to 40% (wb). The date pits was compressed along the width at 0.08, 0.46, 0.55 and 0.64 (db) moisture contents to determine required force, deformation, and energy per volume (toughness) at rupture point. The results showed that the greatest length, width, thickness were 24.43, 9.21, 7.15 mm, respectively at moisture content of 40 % (wb). With increase moisture from 7% to 40% (wb) the true density of... |

| The aim of this work was to manufacture the biodegradable nanocomposite films by extrusion from different combinations of cassava starch, xanthan gum and nanoclays (sodium montmorillonite - MMT- Na) and to characterize them according to their microstructure, optical, mechanical and barrier properties. Films were manufactured from nine starch/xanthan/nanoclay combinations, containing glycerol as plasticizer. Scanning electron microscopy (SEM) of the starch-xanthan extruded films showed reticulated surface and smooth interior, indicating that the gum was mostly concentrated on the surface of the films, while starch/xanthan/nanoclays films showed a more homogeneous surface, suggesting that the introduction of nanoclays provided a better biopolymeric... |
