| Heat stress in animal housing is one of the drivers affecting animal productivity and welfare in hot climates, and causing consequent reduced profits for the farmers. The main challenges that livestock breeding faces in hot climates regards how to foster, improve, and assess methods and strategies for animal heat stress abatement. Research studies in this field have generally proposed modifications in herd management and in feeding strategies, breed selection, and engineered solutions aimed at exploiting heat transmission phenomena. In this paper, the most recent engineered solutions for animal heat stress abatement in livestock buildings have been reviewed and described; they have involved new building and ventilation design and modelling, and improved... |

| Leaves scattered on the parks, passages, and other places have a detrimental effect on the beauty of the environment, and decrease photosynthesis, hence, the efficiency of plants. Leaves are also used in the production of peat. This makes using leaves collectors in parks, and organizations with a green space useful. Due to the fact that leaves take up a high volume, their transportation is difficult. Using the machine introduced in this paper which was equipped with a suction-blower system, increases efficiency, and at the same time decreases the costs of green space, and their workforce cost. Focusing on overcoming the mentioned difficulties, this study was carried out in order to design and produce a tractor powered leaves collector equipped with... |

| Traditionally, the unit farm operations which require less muscle power is done by the women workers. The role of farm women are passive in majority of farm operations e.g. clod breaking, taking out weeds etc., assistance in sowing e.g. dropping seeds or carrying seeds, weeding and interculture, harvesting, partly threshing as well as assistance in threshing, winnowing, cleaning-grading, carrying produce as well as grain. During last three decades, many research organizations in the country are working on assessment, refinement and development of gender friendly farm equipment. Based on various study conducted on gender perspective, a need was felt to work on algorithm, as algorithms design is a specific method to create a mathematical process in solving... |

| This research work involves the design and fabrication of Irvingia nut cracking machines. It operates using impact technique which involves collision between the seednut and stationary wall. The procedures employed the design stage, fabrication and testing. The machine components are: impact drum, shaft, impeller (rotor), electric motor, driver and driven pulley and hopper. The cracking chamber consists of the impeller and impact drum. The seednuts were pre-treated before testing by sun-drying to improve its crackability. The machine gave a better performance at the speed of 2600 revolution per minute with average cracking efficiency, percentage kernel breakage and capacity of 88%, 17.5% and 916 nuts/hr. The improvement in the design can be achieved by... |

| This work addresses the design and configuration of a Eulerian sediment trap mooring array, which was deployed at the shelf edge (zm ≈ 140 m) 80 km off Cabo Frio, SE- Brazil (23° S). The site was subject to interplay between the Tropical Waters (TW) of the Brazil Current (BC), intrusions from the South Atlantic Central Waters (SACW), which are the source of upwelling in the region, and other oceanographic processes. Detailed computations were used to optimize the total weight, buoyancy balance, and maximum acceptable tilt to avoid hydrodynamic bias in the trapping efficiency and array adaptation to the local oceanographic conditions with the assistance of Matlab and Muringa programs and Modular Ocean Model 4.0 (MOM; i.e., to assert the vertical... |

| Irrigation systems should be a relevant agent to give solutions to the increasing demand of food, and to the development, sustainability and productivity of the agricultural sector. The design, managing, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops and orchards. The aim of this paper is to analyze knowledge and investigations that enable to identify the principal criteria and processes that allow improving the design and managing of the irrigation systems, based on the basic concept that they facilitate to develop agriculture more efficient and sustainable. The design and managing of irrigation systems must have its base in criteria that are relevant,... |
