This paper discusses the use of geometric approach to classify different types of trash (non-lint, non-fiber material) in ginned cotton. Pieces of trash can have complicated shapes, so we would like to find a good approximating family of sets. Which approximating family is the best? We reduce the corresponding optimization problem to a geometric one: namely, we show that, under some reasonable ...

ABSTRACT Soil fertility amendments, including composted cotton-gin trash, swine manure, a rye-vetch green manure, or synthetic fertilizers, were applied to subplots and tillage on bare soil; or tillage followed by surface mulch with wheat straw were applied to main plots to determine the effect on the incidence of southern blight caused by Sclerotium rolfsii, yield of processing tomato, and soi...

As machine design in the cotton ginning industry advances, the trend is towards systems that allow for dynamic adjustment of cleaning capabilities. There is however, a lack of real-time sensors suitable for detection of the trash content that would allow for determination of the trash content before the machine performs the cleaning. Current state of the art sensors typically sense the product’...

Analysis of data from the long term trash management trial at Mount Edgccombe (BTI) has shown that, after 59 ycars of green cane harvesting, with trash retention there was a significant incr-ease in soil organic matter content in thc surface 10 cm of soil compared with burning. The size of the microbial biomass, and its rcspiratory rate, dchytlrogenase activity and arginine ammonification rate ...

There is concern that cotton gins may serve as loci for reintroduction of boll weevils, Anthonomus grandis grandis Boheman, to eradicated or suppressed zones when processing weevil-infested cotton from neighboring zones. Previous work has shown that virtually all weevils entering the gin in the seed cotton will be removed before they reach the gin stand. Those not killed by the seed cotton clea...

At a wetland study site in Tuskegee National Forest, AL, resting female mosquitoes were collected from natural and artificial resting sites to identify species-specific resting sites and to evaluate various artificial resting sites for their utility in collecting resting mosquitoes. Natural resting sites included small tree cavities, large tree cavities, and understory vegetation. Artificial re...

New and rapidly evolving tracking technologies are major tools for addressing these challenges because they provide visibility to t...

This study aimed to assess the amount of plate waste and how plate waste was disposed by early adolescent girls using a mobile food record (mFR). Participants were girls nine to thirteen years residing in O'ahu, Hawai'i (n = 93). Foods selected and leftover were estimated using a three day mFR. Each leftover food was then classified as thrown into the trash, fed to a pet, eaten later, or other ...

This paper reports on the yield and nutritional trends over 61 years as affected by various treatments (trashed, burnt with tops either left or removed and all plots either fertilised or not fertilised) of the burning and trashing trial (BT1) at Mount Edgecombe. The overall mean residual yield benefit due to trashing was 9.3 tc/ha/an after 39 crops. The capacity of the Arcadia soil form (Vertis...
