Psychoacoustic evaluation of a garden tractor noise CIGR Journal
Lashgari, Majid; Maleki, Ali.
In addition to achieving sustainable development of agricultural mechanization, it has causing problems on occupational health and safety for people working in different fields of agriculture. Noise is considered as one of the most debilitating conditions in farming and a comprehensive investigation of this relationship is required. In this study, some factors affecting the noise generated by a Goldoni garden tractor were evaluated. Research factors were including engine speed, gear ratios and type of operation. Accordingly, factorial experiments in completely randomized design with three replicates were performed. According to variance analysis with LAeq, PA and UBA, operation type, gear ratio and engine speed were found to be significant (P< 0.01)....

Investigation of energy inputs and CO2 emission for almond production using sensitivity analysis in Iran CIGR Journal
Salehi, Marzie; Maleki, Ali; ghasemi mobtaker, hasan; Rostami, Sajad; Shakeri, Hossein.
The objective of this study is to examine input–output energy and CO2 emission of almond production in Shahrekord region, Iran. This article presents a comprehensive picture of the current status of energy consumption and some energy indices like energy use efficiency, energy productivity, specific energy and net energy gain. Sensitivity analysis of energy was carried out using the marginal physical productivity (MPP) technique. For this propose data were collected from 29almond farms using a face to face questionnaire. The results revealed that total energy input for almond production was found to be 106.61GJ/ha where the electricity was the major energy consumer (59.58%). The direct energy shared about (50.98%) whereas the indirect energy did (49.02%)....
