LDEF: A bibliography with abstracts

The Long Duration Exposure Facility (LDEF) was a free-flying cylindrical structure that housed self-contained experiments in trays mounted on the exterior of the structure. Launched into orbit from the Space Shuttle Challenger in 1984, the LDEF spent almost six years in space before being recovered in 1990. The 57 experiments investigated the effects of the low earth orbit environment on materials, coatings, electronics, thermal systems, seeds, and optics. It also carried experiments that measured crystals growth, cosmic radiation, and micrometeoroids. This bibliography contains 435 selected records from the NASA aerospace database covering the years 1973 through June of 1992. The citations are arranged within subject categories by author and date of publication

Plugging Abandoned Water Wells

Underground waters are one of the most valuable mineral resources of Iowa and each year they are being more widely used. Since the supply of potable waters is limited, their conservation is a matter for careful consideration. Every effort should he made to guard against contamination and loss. One of the chief causes of mineralogical and bacteriological contamination and loss of desirable water is underground circulation from one water-bearing horizon to another in old or abandoned wells. Plugging abandoned wells, provided it is properly clone, is the best method known to prevent underground circulation. The advantages of cement, mud-laden fluids and other plugging media are discussed. The various methods of emplacing the plugging media are outlined

Locomotion in Response to Shifting Climate Zones: Not So Fast

Although a species’ locomotor capacity is suggestive of its ability to escape global climate change, such a suggestion is not necessarily straightforward. Species vary substantially in locomotor capacity, both ontogenetically and within/among populations, and much of this variation has a genetic basis. Accordingly, locomotor capacity can and does evolve rapidly, as selection experiments demonstrate. Importantly, even though this evolution of locomotor capacity may be rapid enough to escape changing climate, genetic correlations among traits (often due to pleiotropy) are such that successful or rapid dispersers are often limited in colonization or reproductive ability, which may be viewed as a trade-off. The nuanced assessment of this variation and evolution is reviewed for well-studied models: salmon, flying versus flightless insects, rodents undergoing experimental evolution, and metapopulations of butterflies. This work reveals how integration of physiology with population biology and functional genomics can be especially informative

Use and Avoidance of Seclusion and Restraint: Consensus Statement of the American Association for Emergency Psychiatry Project BETA Seclusion and Restraint Workgroup

Issues surrounding reduction and/or elimination of episodes of seclusion and restraint for patients with behavioral problems in crisis clinics, emergency departments, inpatient psychiatric units, and specialized psychiatric emergency services continue to be an area of concern and debate among mental health clinicians. An important underlying principle of Project BETA (Best practices in Evaluation and Treatment of Agitation) is noncoercive de-escalation as the intervention of choice in the management of acute agitation and threatening behavior. In this article, the authors discuss several aspects of seclusion and restraint, including review of the Centers for Medicare and Medicaid Services guidelines regulating their use in medical behavioral settings, negative consequences of this intervention to patients and staff, and a review of quality improvement and risk management strategies that have been effective in decreasing their use in various treatment settings. An algorithm designed to help the clinician determine when seclusion or restraint is most appropriate is introduced. The authors conclude that the specialized psychiatric emergency services and emergency departments, because of their treatment primarily of acute patients, may not be able to entirely eliminate the use of seclusion and restraint events, but these programs can adopt strategies to reduce the utilization rate of these interventions
