Wilhelm, W.W., Hinze, M.R. and Gardner, C.O., 1991. Maize hybrid response to tillage under irrigated and dryland conditions. Field Crops Res., 26: 57-66. The popularity of reduced-tillage cropping systems has emphasized the need to determine if maize (Zea mays L.) developed under conventional tillage systems (moldboard plow, disk, and harrow) is readily adaptable to conservation production syst...

An innovative task learning system called PLOW (Procedure Learning On the Web) lets end-users teach procedural tasks to automate their various web activities. Deep natural understanding and mixed-initiative interaction in PLOW makes the teaching process very natural and intuitive while producing efficient/workable procedures.

• Use of Berken plow and intercropping with pigeon pea improves soil characteristics. Root penetration resistance increased maize roots penetrating 1.2–1.5 times deeper. had the greatest available storage 56 cm smallest runoff in both years. Increases infiltration resulted moisture retention up to 60 depth. productivity a positive net benefit. Closing yield gap enhancing efficiency rainfed prod...

A pilot cropland carbon sequestration program within north central Montana has allowed farmers to receive carbon credit for management adjustments associated with changing from tillage-based agricultural systems to no-till. Carbon credit can also be obtained by adopting conservation reserve, where cropland is planted into perennial vegetation. Summer fallowing is also considered within the cred...

disk plows are one of the most important tillage tools. two way (reversible) disk plows can perform continues plowing. so they can save time and costs and hence improve overall efficiency. in this study, a “two-way” disk plow was designed based on a λ-formed straight-line, four-bar linkage (daniel mechanism). this design contains disk and rear wheel reversing mechanism, stabilization mechanism ...

A microtubule (MT) is a tubular stiff filament formed by a hierarchical organization of tubulin proteins. We develop a stochastic kinetic model for studying the strength and stability of a preformed attachment of a MT with a rigid wall where the MT is tethered to the wall by a group of motor proteins. Such an attachment, formed by the specific interactions between the MT and the motors, is an a...

With the advance of packing techniques, a few generic and automatic unpackers have been proposed. These unpackers are designed to automatically unpack packed binaries without specific knowledge of the packing techniques used. In this paper, we present an automatic packer with which packed malware forges spurious unpacking behaviors that lead to a denial-of-service attack on host-based generic u...

We empirically investigate the effects of beef packer concentration and size efficiencies, packer procurement and pricing methods, and other market variables and quality characteristics on the prices paid by packers for slaughter cattle. We find that packers pay less for fed cattle in more concentrated regions. However, we find that concentration is only one of numerous market factors determini...

We report on an instrument for applying ac and dc magnetic fields by capturing the flux from a rotating permanent magnet and projecting it between two adjustable pole pieces. This can be an alternative to standard electromagnets for experiments with small samples or in probe stations in which an applied magnetic field is needed locally, with advantages that include a compact form-factor, very l...

Post-Conservation Reserve Program (CRP) land may provide an excellent opportunity to satisfy certified organic crop production requirements. However, conversion of CRP or long-term pastureland to certified organic production will require tillage because the use of herbicides is prohibited in organic production. Our objectives were to evaluate stand establishment, weed competition, yield, and gr...
