This bulletin updates HAES Bulletin 12 (1906) by J.E. Higgins to meet the increasing demand for information on this popular fruit in Hawaii.
The systems theory is discussed in relation to safety management. It is suggested that systems safety management, as a new discipline, holds great promise for reducing operating errors, conserving labor resources, avoiding operating costs due to mistakes, and for improving managerial techniques. It is pointed out that managerial failures or system breakdowns are the basic reasons for human errors and condition defects. In this respect, a recommendation is made that safety engineers stop visualizing the problem only with the individual (supervisor or employee) and see the problem from the systems point of view.
The data presented in this bulletin represent the results of 20 years' work with the Guatemalan avocado at the Hawaii Experiment Station.
Citrus fruits had been under investigation at the Experiment Station since 1904, and 40 different species and varieties were represented in the experimental orchard. This bulletin contains descriptions of these materials and summarizes recommendations on their cultivation and the control of various pests and diseases affecting them in Hawaii.
This bulletin provides comprehensive information on passion fruit, so that the plant, previously grown mostly in home gardens, might be adopted for commercial cultivation. Six species/types are described.
Varieties of lime grown in Hawaii were described, along with methods of propagation, planting and crop maintenance practices, insect pests, plant diseases, fruit composition and uses, and recipes. The author judged limes, introduced in the early 19th century, to be the best adapted of the citrus species to Hawaii's conditions.
Abstract not available.
The paper reports on the development of current leads for an orbiting superconducting magnetic spectrometer that were required to achieve a zero-current heat leak of 0.03 W with a total coolant flow rate as low as 0.011 g/sec cooling only the coldest third of the length of a lead. Analysis of heat flow phenomena in an insulated current lead in thermal contact with cryogenic gas flow is given for prediction of lead performance. A basic lead design was then tested and modified by such techniques as tapering, adding superconducting sections, and operating above the optimum current, until a lead satisfying the low-leak requirements was obtained. Operating the insulated leads at well above their optimum current for short periods at high mass flow is possible, and instability behavior is predictable.
An apparatus is described for phase separating a gas-liquid mixture as might exist in a subcritical cryogenic helium vessel for cooling a superconducting magnet at low gravity such as in planetary orbit, permitting conservation of the liquid and extended service life of the superconducting magnet.
