Many important ecosystem services show spatial flow characteristics, which are crucial for the study of environmental processes, such as transformation, correlation, coordination, and management at different scales. As a result, characteristics should be taken into account when it comes to evaluation services. The area was Baijitan Nature Reserve, used assess radiating benefits windbreak sand f...

Of all the agricultural pests and diseases that threaten citrus crops, citrus canker is one of the most devastating. The disease, caused by the bacterium Xanthomonas axonopodis pv. citri, occurs in large areas of the world's citrus growing countries including India. At least 3 distinct forms or types of citrus canker are recognized. Among these, Asiatic form (Canker A) is the most destructive a...

Emissions odors, gases, and dust from livestock production facilities arise primarily from three sources; buildings, manure storages, and land application (1). Emissions from buildings and storages form a baseline emission level. Eliminating emissions from one of the sources will likely not eliminate emissions entirely. Control technologies often address only one of the three sources. Many of t...

Abstract Environmental wind measurements are essential for ensuring the operational safety of rail vehicles. In our previous work, an anemometer that can be mounted on top a train to achieve real-time speed and direction was proposed based pressure distributions around cylindrical anemometer. However, flow field is significantly influenced by train; thus, measured data might differ from actual ...
