PASCAL/48 reference manual
PASCAL/48 is a programming language for the Intel MCS-48 series of microcomputers. In particular, it can be used with the Intel 8748. It is designed to allow the programmer to control most of the instructions being generated and the allocation of storage. The language can be used instead of ASSEMBLY language in most applications while allowing the user the necessary degree of control over hardware resources. Although it is called PASCAL/48, the language differs in many ways from PASCAL. The program structure and statements of the two languages are similar, but the expression mechanism and data types are different. The PASCAL/48 cross-compiler is written in PASCAL and runs on the CDC CYBER NOS system. It generates object code in Intel hexadecimal format that can be used to program the MCS-48 series of microcomputers. This reference manual defines the language, describes the predeclared procedures, lists error messages, illustrates use, and includes language syntax diagrams
SALES RESPONSES TO RECALLS FOR LISTERIA MONOCYTOGENES: EVIDENCE FROM BRANDED READY-TO-EAT MEATS
Empirical models are used to measure sales losses experienced by frankfurter brands following a recall for a foodborne pathogen. Recalled brands experience a 22 to 27 percent sales decline after a recall. Brand recovery occurs within 4 to 5 months after a recall. Non-recalled brands do not experience sales losses.Food Consumption/Nutrition/Food Safety,
Design and evaluation of fluidized bed heat recovery for diesel engine systems
The potential of utilizing fluidized bed heat exchangers in place of conventional counter-flow heat exchangers for heat recovery from adiabatic diesel engine exhaust gas streams was studied. Fluidized bed heat recovery systems were evaluated in three different heavy duty transport applications: (1) heavy duty diesel truck; (2) diesel locomotives; and (3) diesel marine pushboat. The three applications are characterized by differences in overall power output and annual utilization. For each application, the exhaust gas source is a turbocharged-adiabatic diesel core. Representative subposed exhaust gas heat utilization power cycles were selected for conceptual design efforts including design layouts and performance estimates for the fluidized bed heat recovery heat exchangers. The selected power cycles were: organic rankine with RC-1 working fluid, turbocompound power turbine with steam injection, and stirling engine. Fuel economy improvement predictions are used in conjunction with capital cost estimates and fuel price data to determine payback times for the various cases

Buckling mediated by mobile localized elastic excitations
Experiments reveal that structural transitions in thin sheets are mediated by
the passage of transient and stable mobile localized elastic excitations. These
``crumples'' or ``d-cones'' nucleate, propagate, interact, annihilate, and
escape. Much of the dynamics occurs on millisecond time scales. Nucleation
sites correspond to regions where generators of the ideal unstretched surface
converge. Additional stable intermediate states illustrate two forms of
quasistatic inter-crumple interaction through ridges or valleys. These
interactions create pairs from which extended patterns may be constructed in
larger specimens. The onset of localized transient deformation with increasing
sheet size is correlated with a characteristic stable crumple size, whose
measured scaling with thickness is consistent with prior theory and experiment
for localized elastic features in thin sheets. We offer a new theoretical
justification of this scaling.Comment: contains link to video
The Role of the Business Press as an Information Intermediary
This paper investigates whether the business press serves as an information intermediary. The press potentially shapes firms\u27 information environments by packaging and disseminating information, as well as by creating new information through journalism activities. We find that greater press coverage reduces information asymmetry (i.e., lower spreads and greater depth) around earnings announcements, with broad dissemination of information having a bigger impact than the quantity or quality of press-generated information. These results are robust to controlling for firm-initiated disclosures, market reactions to the announcement, and other information intermediaries. Our findings suggest that the press helps reduce information problems around earnings announcements
