My farm consists of 225 acres on hilly land in Lancaster County, PA. We grow a diversity of crops and our early tomatoes are grown in two acres of multi-bay high tunnels. I reluctantly was forced to fumigate in the tunnels due to problems with verticillium wilt (race 2). At my farm, we have looked at grafting to manage verticillium and other soilborne diseases in our tunnels, and have seen that...

In this paper we extended the 3D skeletonization method based on Euler number count & cluster count to 4D. As the Euler sum in 4D is always 0, we solved this by embedding 4D objects in a 5D space to calculate the 5D Euler number. The 5D Euler number changes due to 3 events: 1D tunnels, 2D tunnels and 3D tunnels. As the latter does not occur in 4D objects, together with a foreground and a backgr...

Chimpanzees (Pan troglodytes) competed with a human for food. The human sat inside a booth, with 1 piece of food to her left and 1 to her right, which she could retract from her chimpanzee competitor's reach as needed. In Experiment 1, chimpanzees could approach either side of the booth unseen but then had to reach through 1 of 2 tunnels (1 clear, 1 opaque) for the food. In Experiment 2, both t...

Many research works are going on to save or protect the environment from different hazardous or toxic gases, chemicals and other harmful effects. Different construction materials (both renewable & non-renewable) are used while constructing any structure, road, railway, tunnel, etc. But every Engineer must know the concept of sustainable development and the particular application of construction...

An accurate characterization of the near-region propagation of radio waves inside tunnels is of practical importance for the design and planning of advanced communication systems. However, there has been no consensus yet on the propagation mechanism in this region. Some authors claim that the propagation mechanism follows the free space model, others intend to interpret it by the multi-mode wav...

Although double-bundle anterior cruciate ligament (ACL) reconstruction has theoretical benefits such as more accurate reproduction of ACL anatomy, it is technically more demanding surgery. This report describes the case of a one stage revision single-bundle ACL reconstruction after primary double-bundle ACL reconstruction. A professional dancer had an ACL previously reconstructed with a double-...

A processing system has been developed to meet increasing demands for detailed noise measurement of aircraft in wind tunnels. Phased arrays enable spatial and amplitude measurements of acoustic sources, including low signal-to-noise sources not measurable by conventional measurement techniques. The Microphone Array Phased Processing System (MAPPS) provides processing and visualization of acoust...

The Himalayan Rivers due to their steep bed and side slopes, narrow width and fragile geology of the region carry huge amount of sediment with them. Many runof-river hydro power projects are coming up on these rivers and suspended sediment enters into the power intake of these projects. Desilting chambers are provided to remove / minimize the suspended sediment from water conductor system. The ...

Originally, the Internet delivered best-eeort service quality with respect to end-to-end delay. Recently, extensions such as RSVP have been proposed to provide guaranteed real-time services as well. Unfortunately, network resources, such as routers, do not yet fully support RSVP reservation protocols so that guarantees cannot truly be given. In this paper , we suggest to follow the paradigm of ...
