mechanical damage due to harvesting, handling, and other processes is an important factor that affects the seeds quality. seed damage results in lower grain value and more storability problem and reduces seed germination and seedling vigor and subsequent yield of crops. tests were conducted to determine the percentage of physical damage (ppd) and percentage of loss in germination (plg) of wheat...
mechanical damages inflicted upon seeds in harvesting, handling and further subsequent processes are worth attention because they unfavourably influence the quality of seed. seed damage results in lower grain value, storage problems, and reduced seed germination and seedling vigor, resulting in a subsequent diminishing yield of future crops. the present experiments were conducted to determine t...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
Any mechanical force exerted on a potato tuber during the harvesting may result in mechanical damage. A few weeks prior to harvesting, haulm destruction could improve the rheological properties of the tuber and reduce its susceptibility to mechanical damage. The effects of elevator and oscillatory sieve diggers and haulm destruction on potato loss and mechanical damage were studied on a farmer ...

improper transportation of agricultural materials causes mechanical damage to them. the damage isdepended to the physical and mechanical properties of the product and properties of the appliedforce. vibration generated by vehicles during road transportation causes shake the product, contactit with carrier bin and other components, tissues deformation and damage to product. this researchwas cond...
The selection and design of materials that will withstand the extreme conditions of a fusion power plant has been described as one of the greatest materials science challenges in history. The high particle flux, high thermal load, thermal mechanical stress and the production of transmutation elements combine to produce a uniquely hostile environment. In this paper, the materials favoured for th...
