Automated Control Logic for Naturally Ventilated Agricultural Structures
An innovative control strategy for a naturally ventilated (NV) swine finishing building was evaluated. Extensive monitoring of an existing NV-controlled swine finishing building indicated that the building temperature control was .3.C of set-point for less than 50% of the time, with 20% of the time greater than .6.C. Based on the experience gained from this monitoring, the building was modified...

متن کاملStructural strength evaluation of driver's protective structures for self-propelled agricultural machines.
The high number of accidents due to rollovers of agricultural machines has increased the interest of researchers and organizations for standardization in this field. In the 1960s, standards to test rollover protective structures (ROPS) for tractors were designed and approved. Similar standards were introduced in the 1990s for earth-moving machinery, but ROPS standards were not defined for self-...
متن کاملThe importance of semi-natural landscape structures in an agricultural landscape as habitats for stenotopic spiders
The development of agricultural landscapes during the last decades has been characterized by an increase in management intensity, and a consequent decrease in the number and size of natural and semi-natural habitats. As a result, isolation of populations of stenotopic species of forests, shores, heathers, etc., has increased. This is a serious problem, especially for smaller invertebrates with ...
