| As the world progresses, more energy is required to get along with everyday changes. Using bio-ethanol as one of the most important bio-fuels is an appropriate response to those changes. Much agricultural waste is being produced in Iran and the combination of such waste can turn it into a good source for the production of bio-ethanol. Thus, in this study, the amount of bioethanol extracted from melon waste was measured and evaluated. To do so, considering the 15 kg capacity of the device's fermenter, 12 kg of refined melon sugar syrup and three kilograms of water (with the standard ratio of 4 to 1), i.e. a total of 15 kg of substrate with the brix degree of 20, as well as 75 gr of saccharomyces cervisiae yeast, cultured in standard conditions (5 grams of... |

| Whole body vibration is one of the main causes of musculoskeletal disorders of drivers. The purpose of this study was to investigate the allowable exposer time, the care limit and driver response to the vibrations of the seat of ITM 475 Tractor. A three-way accelerometer was used to carry out the tests in the present study based on the ISO 2631-1 international vibration standard. The studied factors were engine rotational speed at three levels of 1000, 1500 and 2000 rpms, gear ratio (1, 2 and 3) and road at two level, dirt and asphalt. The obtained data were analyzed through factorial experiment based on completely randomized design with 18 treatments and three replications. The results showed that effects of the main factors and those of their... |

| 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... |
