For the early Iron Age Elymian town on Monte Polizzo, inland western Sicily, hulled barley was the dominant cereal, followed by emmer and free-threshing wheat. The dominant legume was Vicia faba. In the contemporary Greek harbour town of Selinunte on the southern coast of western Sicily, free-threshing wheat was dominant, while hulled barley and the legume V. ervilia were subdominant. For Selin...

∗ This work is supported with funds of the Deutsche Forschungsgemeinschaft within the priority program "Rapid Prototyping for Integrated Control Systems with Hard RealTime Constraints" Abstract: This paper describes a rapid prototyping system for the design and development of hard real time systems. The main focus of this rapid prototyping system is on scheduling algorithms. Issues of their imp...

The modern strategy for the development of mechanization agricultural production provides an increase in productivity and quality work aggregates, including grain harvesting equipment. Combine harvester main machine, which determines efficiency entire transport complex. working body combine is a threshing separating device that productivity, as well loss grain. Many studies have found potential...

there are different methods used for threshing of grain crops. usual threshers operate based on the impact force (in threshing unit) that may damage the grains. in another method named axial-flow, grain damage is less so these types of the harvesting machines are being used more than before. in this study one of the common rice threshers (model t30) locally made in ashtad company was modified t...

a prototype of a straw chopper, equipped with a discharge system was designed and fabricated in the department of mechanics of agricultural machinery, university of tehran, karaj, iran. to test for the effective performance of the machine, the effects of such parameters as: drum speed (at three levels of: 400, 540, and 800 rpm), screen size (at two levels: 2.5 and 4 cm), and number of blades on...

We developed an adaptive algorithm to reduce rice loss in harvesting, promote threshing and improve the quality efficiency of small- medium-sized harvesters operating southern China’s hilly mountainous areas. Using a fuzzy PID control algorithm, harvester adapts harvesting conditions China, monitors feed volume changes instantly adjust traveling speed optimize levels quality. compared analyzed ...

The study was conducted on 20 farm workers to identify the occupational health hazards in threshing operation. Four different protective masks were given and tested on various parameters. Respondents reported respiratory health problems which were mainly due to heat and organic dust in the surroundings. All respondents reported irritation in eyes and throat followed by nose (85.0%) and ears (75...

Recent spectroscopic and morphological observational studies of galaxies around NGC 1399 in the Fornax Cluster (Drinkwater et al. 2000b) have discovered several ‘ultra-compact dwarf’ galaxies with intrinsic sizes of ∼ 100 pc and absolute B band magnitudes ranging from −13 to −11 mag. In order to elucidate the origin of these enigmatic objects, we perform numerical simulations on the dynamical e...

Women are involved in planting, transplanting, weeding, harvesting and processing activities in paddy cultivation system. These operations are most drudgeries activities performed by them. During these operations the women face many physical and physiological problems. Keeping this in view the physical strain with respect to working heart rate (WHR), Oxygen consumption rate (OCR), Energy expend...
