Notizen: A mathematical model of microwave thawing of homogeneous food products is developed and solved numerically using the Modified Isotherm Migration Method. The model is used to predict thawing time and temperature profiles for microwave thawed meat cylinders at three frequencies (2450 MHz, 915 MHz, 300 MHz) and different power levels. Model and experimental results for thawing a lean beef cylinder heated at low microwave power using 2450 MHz frequency compare well. The advantage of using 915 or 300 MHz power over 2450 MHz power is shown by calculations. The results show that microwaves significantly accelerate the thawing rate. The mathematical model is explored as a tool for designing optimal microwave/convective heating protocols for rapidly thawing foods in desired temperature ranges.

Notizen: Increased attention is being directed toward the investigation of tight zones in relation to the storage and disposal of hazardous wastes. Shut-in tests, slug tests, and pressure-slug tests are being used at the proposed Waste Isolation Pilot Plant site, located in southeastern New Mexico, to evaluate the fluid-transmitting properties of several zones above the proposed repository zone. Apparatus used to conduct these tests includes a pressure-transducer system connected to a recording device at the land surface. All three testing methods were used in various combinations to obtain values for the hydraulic properties of the test zones. Multiple testing on the same zone produced similar results. Transmissivities determined by these tests range from 0.00001 to 10 feet squared per day (.000001 to 1 meter squared per day).

Notizen: Accidental events such as fires, explosions, and leaks often result in large-scale contaminations of buildings with toxic chemicals. After decontamination, the certification for original use requires testing for residual contamination. The two basic kinds of sampling plans in use up to recently both fall short of the required performance. Their deficiencies are analyzed in terms of the scientific questions implicit in both the sampling plan and the subsequent statistical evaluation. A sampling strategy of a new kind is proposed and discussed in the same context. It is motivated by concern for the long-term safety of the building's occupants and is, therefore, based on factors important in risk assessment. Three different sampling plans are derived in the framework of this methodology, two of which have already been used in actual certification proceedings.

Notizen: The effects of field application rates, number of applications, interval to harvest after field treatment with ethylenebisdithiocarbamate (EBDC) fungicide and the effect of washing on the levels of the residue ethylenethiourea (ETU) in canned spinach were studied. High rates of applied EBDC high number of field applications and applications closer to harvest time resulted in canned spinach with high levels of ETU. Washing with water before processing significantly reduced the levels of ETU in spinach from all the field treatments, but washing with a solution of sodium hypochlorite and a mild detergent reduced even further the levels of ETU.

Notizen: The purpose of this work is to demonstrate the predictive capability of the Oak Ridge National Laboratory finite-element computer model of water flow through aquifers, FEWA. The computer code for FEWA was written by G. T. Yeh and D. D. Huff. The area investigated was the Hialeah-Preston wells in Miami, Florida over the Biscayne aquifer. The field data of May 3, 1977, for the area were used for calibration of the model. The model was then integrated over time until October 4, 1977, using the data on rainfall, infiltration, and pumpage of wells during that period. The predicted potentiometric head for the area compared well with the field data. It may be concluded that substantial confidence in the predictive capability of the model has been established for the site in Florida.
