				<dcterms:abstract><![CDATA[The goal of this investigation is weighting and selecting chickens in a determined weight by using machine vision. The images were taken by Raspberrypi cameras and then processed using the Raspberrypi 3 board, and finally the weight was estimated. The marking system was also used to mark chickens in the ideal weight range. For this purpose, 300 Rass chickens were examined in 3 poultry farms by a portable system and from about 500 pictures, 4 features were extracted: length, width, area and circumference. Chickens weight calculated with mixing features (length, width, area) that had been gained. Average percentage error of each one was also measured separately. Average percentage error in this system was 6% (minimum error percentage 2% and maximum error percentage 12%) that indicates the ability of image processing to determine the weight of the chicken. For check system accuracy, one place similar to poultry farms has designed with the same light, temperature, food and water for chickens, and they had access freely, they have been checked for 4 days, then marked chickens were putted up on a digital scale. Finally, the results showed the complete accuracy of the system and the accuracy of the image processing and weighting process]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Saffron corms are planted in Iran in the same way as in other parts of the world in a manual way. The manual planting of corms makes it time consuming and labor-intensive. In this research, a seven-row planter machine with row spacing of 25-30 cm was designed and developed. This machine is capable to plant 5 to 10 tons of saffron corms per hectare. This planter has continuous flow cylindrical feeder on the bottom of the corms container that guided the corms to the furrowers by seven outlets. In order to evaluation of saffron corm planter, the effects of planting speed at three levels (4, 5 and 6 km/h) and plant density at three levels (5, 6 and 7 tons per hectare) on performance, percentage of injury’s corms, none-planting and multiple-planting indices, distribution uniformity of corms around the set distance and around the mean of the obtained distances were investigated. Statistical analysis was done on randomized complete block design applying the analysis of variance (ANOVA). The results showed that the percent of corms distribution uniformity around the set distance and around the mean of the obtained distances was 90% and 82% at a speed of 5 km/h, respectively. The nominal and effective performance was calculated as 1 and 0.66 ha / h, respectively. It was also found that with increasing planting density, the none-planting and multiple-planting indices increased from 0.1 to 0.075 and from 0.12 to 0.25, respectively.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Discrete element method has been identified as a suitable method for studying the flow of granular materials. In this research, the motion of Persian lilac fruit was initially investigated experimentally in a slopped hopper and then it was simulated using discrete element method. The experiments were carried out on the basis of factorial design with two factors of height and discharge area, each at four levels. The ANOVA tests indicated that the height of the fruits in the hopper and the surface area of the discharge and their interaction had a significant effect on the outflow of the fruits. The developed regression equation between the mass flow rate and discharge area and the interaction of discharge area and height was linear (R2 = 0.99), however, height of the fruits in the hopper had a negative impact on the discharge rate. The simulation results indicated that and the outlet size, the discharge flow and the output velocity increase, but they did not exactly follow the fluid flow relationships. The effect of fruits friction showed that the discharge rate increased with decreasing internal friction. In general, comparing the simulation results with laboratory tests showed that the discrete element method was well able to simulate the flow of particles within and through the hopper.]]></dcterms:abstract>

Independent parameters included the threshing cylinder speed (TCS), the distance between the threshing cylinder and concave or threshing space (TS) and moisture content (MC). Azargol variety was used to evaluate the threshing unit. The tests were performed at 3 TCS levels (280, 380 and 480 rpm), 2 TS levels (8 and 10 cm) and 2 MCs of sunflower head proportional to crop condition (20 and 45% wet basis). Results of analysis of variance show that the effect of TCS, MC, and TS on power consumption are significant and the effect of MC and TS are not significant on the threshing efficiency but the effect of TCS is significant on it. with increasing in TCS, MC, and TS, power consumption was increased. But threshing efficiency was increased just with increasing in TCS. After defining the ANN model the optimal operation point for minimize power consumption and maximize threshing efficiency was determined that it was 10, 600 and 11.5 for MC, TCS and TS respectively.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Pests and disease control have always been one of the main concerns and challenges of farmers and growers. The use of machine vision and image processing has greatly helped growers in pest management. The purpose of this study was to use image processing technique to detect honeydew produces by pistachio psylla and find the relation between the percent of leaf coverage by honeydew and pistachio psylla infestation. The leaves were collected from the research orchard with various infestation rates. Leaf samples were imaged by three cameras with 7, 13 and 20.7 MP resolutions at the same exposure conditions in imaging chamber with controlled lighting conditions. Images were processed in the Matlab R2019a using Watershed and Otsu segmentation algorithms to find the percentage of leaf surface covered by honeydew. The covered area was calculated using predefined functions in the image processing toolbox. A graphical user interface (GUI) was also designed to make the program more user friendly. Considering TPR mean value of 0.95 and total accuracy of 0.88 for watershed segmentation method showed its acceptable performance in discriminating honeydew out of other objects in images. Coefficient of determination and regression equation between pest population (obtained from manual count by expert) and percentage of leaf area covered by honeydew were obtained for different cameras. Camera with 20.7 MP resolution achieved the best performance with coefficient of determination 0.93 and regression equation y=1.03 x. The results from other cameras were also satisfactory.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Reducing material waste in agricultural production is one of the most important strategies to increase efficiency in the agricultural sector. Accordingly, various methods have been used to measure the economic efficiency and energy of agricultural production. However, most of these methods do not take into account the hidden costs of measuring the efficiency of the production system. Material Flow Cost accounting (MFCA) enables farmers to be aware of the amount of energy and value-added losses that results from material waste. In this study, a new approach (ISO 14,051) was used to measure the economic and energy indicators of canola production in Ardabil province. Data were obtained through face-to-face interviews with 65 farmers in the 2,018. According to the obtained results, the highest amount of input energy is related to fossil fuels and nitrogen fertilizer. Based on energy and economic indicators calculated by two methods of conventional accounting and accounting based on material flow cost accounting, it was found that the total value of canola production according to conventional accounting is equal to 59,055,260 Rials per hectare and in material flow costing is 65,694,700 Rials per hectare. However, in case of reducing material and energy waste (negative production), the benefit-cost ratio in the production process will increase by 0.12 units. Energy efficiency and specific energy were the same in the two accounting approaches because of the non-interference of output energies in their calculation. But net energy in conventional accounting differs by 9,162 megajoules from MFCA. The findings of the present study will help to better understand the issues and challenges related to reducing waste and environmental emissions and optimizing production systems as well as investing in crop production.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[The Maximum energy loss in flat-plate solar collectors is due to top heat loss. The variables of absorber plate temperature, ambient temperature, wind speed, the distance between the absorber plate and the cover, collector length, and tilt angle are effective. In this research, considering the long-term meteorological data and developed relations for the top loss in flat-plate solar collectors in previous researches, including convection, conduction and radiation losses, calculations were performed in the form of Fortran codes. Results showed that the proper value for the distance between the absorber plate and one-layer cover has the range of 11 to 38 mm for some cities of the country. In addition, the sensitivity analysis of the top loss showed that the order of variables from maximum to minimum is wind speed, the distance between the absorber plate and the cover, collector tilt angle, collector length, absorbent plate temperature and ambient temperature.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[In order to evaluate the selection of the best method for rice cultivation from among different methods including: manual weeding, chemical control and mechanical weeding, questionnaires were distributed among farmers and experts of Sowme'eh Sara city in Guilan province. A quantitative and qualitative integration approach was used to analyze the data, and the characteristics were weighed using the entropy method. The comfort of the labor, the amount of environmental pollution, the number of labors needed and the cost have the highest weights, which indicates the importance of these cases for farmers and experts. Multi-indicator methods have a variety of methods at different stages of decision making. In these methods, several options are compared based on several different criteria, and finally the best option or sequence of appropriate options is selected. Using the TOPSIS method, ranking was performed between different weeding methods. The results showed that the highest degree of impact is related to the mechanical weeder with 0.7221, followed by chemical control and manual weeding with importance degree of 0.5019 and 0.3730, respectively. Efforts and support from officials in management, providing skills training, proper culture, and budget allocation for farmers are effective and effective solutions.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[In this study, unrippen grape pomace as a valuable source for pectin extraction was investigated using acidic extraction method. For this purpose, Box-Behnken design with four independent variables in three levels (Time (30-90 min), Temperature (70-90℃), pH (1.5-3.0) and liquid to solid ratio (20-40 v/w)) was used to optimize the pectin extraction yield that the highest pectin extraction yield in the optimum conditions (time of  85 min, the temperature of 90℃, pH of 1.5 and liquid to solid ratio of 20 (v/w)) was 26.1 ± 1.0%. The results showed that unrippen grape pomace pectin had degree of esterification of 51.6%, galacturonic acid content of 66.1%, emulsifying activity of 57.2%, and also showed favorable emulsion stability. The FT-IR spectrum confirmed the presence of esterified poly galacturonic acid structure in pectin sample.]]></dcterms:abstract>

				<dcterms:abstract><![CDATA[Citrus-based drinks are one of the most popular fruit drinks. Juice and paste are high consumption products of sour orange. In the present study, viscosity, specific heat capacity, heat transfer coefficient, density, dry mass matter, pH, electrical conductivity, total dissolved solids, and color characteristics of sour orange extract were investigated during different steps of thermal concentration. Arrhenius and Modified Arrhenius models were also investigated to describe the relationship between viscosity and temperature. By decreasing the ratio of secondary volume of extract to primary volume of juice from 100% to 15%, the values ​​of density, dry mass matter, and pH increased from 1035 to 1340 kg m-3, increasing from 6.89% to 47.45%, and decreased from 2.09 to 1.38, respectively. Also specific heat capacity and heat transfer coefficient decreased from 4146 to 2984 J kg-1 K-1 and decreased from 0.584 to 0.402 W m-2 K-1, respectively]]></dcterms:abstract>
