A review of existing model of no-notice randomized inspection and their potential application to model Pu handling facilities

Literature regarding two alternative safeguards concepts--randomization and zones--is reviewed. The concepts were introduced in the early 1980`s to address the need to make safeguards more efficient in the light of the increasing number of facilities under safeguards and a fixed IAEA inspection budget. The paper discusses literature broadly relating these approaches to IAEA needs and objectives, reports from IAEA consultants meetings, reports of field trials, and other technical papers. The review suggests that the approaches have been extensively considered on a theoretical and practical level, and that the safeguards community endorses them on a conceptual level as potentially valid ways of achieving safeguards objectives. Actual utilization of the ideas in safeguards practice has to proceed on a case-by-case basis, but progress is being made

Bulletin No. 29 - Irrigation: Amount of Water to Use. Relative Feeding Values of Timothy, Lucerne and Wild Hay

In Bulletin 24 are given results of the first three years of experimentation as to the relation between the amount of water used and crop yield, soil fertility, and the exit, through drains, of the matters held in solution in the water applied. In this report are included the results of the first three years, plus those of the past season. The experiment is regarded of the very highest importance in that it deals with the right amount of water essential to the growth of wheat and grass crops, but more especially as it approximately determines whether the materials of plant growth held in solution by irrigating waters are taken up by the soil, or whether the water, in passing through the soil, actually has added to it soluble matters already in the soil before the application of the water

Bulletin No. 30 - Narrow vs. Wide Nutrituve Rations for Horses

In the third annual report of this Station (1892) the result of feeding wide and narrow nutritive rations to horses was given. This trial was favorable to the narrow nutritive ration. This ration was made up of clover, oats and wheat , while the wide ration was made up of timothy and corn. The trial ran through the summer, when the influence of what has been termed heating food, like corn, might be less effective than in the winter season. Many believe that the more varieties of food given the better the result, as the palatableness of food, it is claimed, has a reflex influence on the appetite and digestive system. The weight to be attached to such reasoning is uncertain. The influence of season on the ration to be fed is less doubtful

Bulletin No. 31 - Time to Harvest Lucerne. Mulching.

The opinion has prevailed in scientific as well as in practical circles, that hay cut before or during bloom is more valuable, pound for pound, than when cut at a later period, and it is even maintained that the gross product per acre is more valuable. The old assumption, now somewhat modified, that as plants mature a part of the starch and sugar is converted into fibre, and that the nutrition of the stem is moved into the seed, led to the belief that early-cut hay was both more digestible and more valuable than that cut at a later period. The writer conducted experiments in New Hampshire for four years on the influence of the time of cutting on the value of timothy hay, with the result that the hay cut from eight to fifteen days after bloom was equally as valuable, if not more valuable, than the hay cut in bloom. Scientific men at once claimed that this must be an error. Subsequent experiments by others, however, have demonstrated the correctness of the position then taken, so far as timothy hay is concerned. The same was found in part to be true of clover. The experiments in question showed that hay cut after bloom weighed much more per acre than when cut in bloom

Investigations of lubricant rheology as applied to elastohydrodynamic lubrication

The pressure viscometer was modified to permit the measurement of viscosity at elevated pressures and shear stresses up to 5 x 10 to the 6th power N/sq m (720 psi). This shear stress is within a factor of three of the shear stress occurring in a sliding ehd point contact such as occurs in the ehd simulator. Viscosity data were taken on five lubricant samples, and it was found that viscous heating effects on the viscosity were predominant and not non-Newtonian behavior at the high shear stresses. The development of the infrared temperature measuring technique for the ehd simulator was completed, and temperature data for a set of operating conditions and one lubricant are reported. The numerical analysis of the behavior of nonlinear lubricants in the lubrication of rollers is reported
