Handling Lameness in Cattle
Often cattle suffer extreme lameness when only one claw is affected and there is no involvement of the interphalangeal joints. many times the pain associated with these lesions may be so severe that the animal will not walk to a feed bunk or graze. This inevitably leads to costly weight losses in the feedlot and decreased milk production in the lactating animal. Some examples of these painful single claw afflictions include sole abscesses, nail or rock punctures, and other traumatic injuries
Some Ideas on the Pathogenesis of Neonatal Calf Scours
Neonatal calf scours have been a costly problem for cattlemen for many years. The disease strikes all types of cattle operations although it is most devastating in the intensified cow-calf herd or dairy herd. For the purposes of this paper neonatal calf scours will be defined as that condition of young calves, usually under ten days of age, which is characterized clinically by severe diarrhea and dehydration. with death occurring within a few days if treatment is not begun at the onset and by the absence of lesions characteristic of other diseases
An Atypical Case of Polioencephalomalicia
Polioencephalomalacia (PEM) is a significant feedlot cattle problem here in the midwest. Differentiation of this disease from other diseases that produce central nervous signs such as acute lead poisoning (ALP), thromboembolic meningoencephalomyelitis, hypomagnesemia, and rabies is important to the practitioner as he has to decide on the best course of therapy for recovery
Incorporating inventories into supply and demand analysis
While the paper lacks a formal abstract, it draws the important distinction between stocks and flows in supply and demand to better understand the business cycle
Application of the Nuclear Microprobe to the Imaging of Single Event Upsets in Integrated Circuits
A new form of microscopy has been developed which produces micron-resolution maps of where single event upsets occur during ion irradiation of integrated circuits. Utilizing a nuclear microprobe, this imaging technique can irradiate, in isolation, individual components of an integrated circuit (e.g. transistor drains, gates, feedback resistors) and measure immediately the effect of a high energy ion strike on circuit performance. This detailed circuit characterization technique provides a precision diagnostic with which to evaluate the design of integrated circuits that are to be used in space or other radiation environments

New Glueball-Meson Mass Relations
Using the ``glueball dominance'' picture of the mixing between q\bar{q}
mesons of different hidden flavors, we establish new glueball-meson mass
relations which serve as a basis for glueball spectral systematics. For the
tensor glueball mass 2.3\pm 0.1 GeV used as an input parameter, these relations
predict the following glueball masses: M(0^{++})\simeq 1.65\pm 0.05 GeV,
M(1^{--})\simeq 3.2\pm 0.2 GeV, M(2^{-+})\simeq 2.95\pm 0.15 GeV,
M(3^{--})\simeq 2.8\pm 0.15 GeV. We briefly discuss the failure of such
relations for the pseudoscalar sector. Our results are consistent with
(quasi)-linear Regge trajectories for glueballs with slope \simeq 0.3\pm 0.1
GeV^{-2}.Comment: Extensive revision including response to comments received, value of
glueball Regge slope, and a consideration of radial excitations. 14 pages,

Radiation hardness assurances categories for COTS technologies
A comparison of the radiation tolerance of three commercial, and one radiation hardened SRAM is presented for four radiation environments. This work has shown the difficulty associated with strictly categorizing a device based solely on its radiation response, since its category depends on the specific radiation environment considered. For example, the 3.3-V Paradigm SRAM could be considered a radiation-tolerant device except for its SEU response. A more useful classification depends on the methods the manufacturer uses to ensure radiation hardness, i.e. whether specific design and process techniques have been used to harden the device. Finally, this work has shown that burned-in devices may fail functionally as much as 50% lower in total dose environments than non-burned-in devices. No burn-in effect was seen in dose-rate upset, latchup, or SEE environments. The user must ensure that total dose lot acceptance testing was performed on burned-in devices
