Acceptability of risk from radiation: Application to human space flight

Description: This one of NASA`s sponsored activities of the NCRP. In 1983, NASA asked NCRP to examine radiation risks in space and to make recommendations about career radiation limits for astronauts (with cancer considered as the principal risk). In conjunction with that effort, NCRP was asked to convene this symposium; objective is to examine the technical, strategic, and philosophical issues pertaining to acceptable risk and radiation in space. Nine papers are included together with panel discussions and… more

ELECTROKINETIC DENSIFICATION OF COAL FINES IN WASTE PONDS

Description: The objective of this research is to demonstrate that electrokinetics can be used to remove colloidal coal and mineral particles from coal-washing ponds and lakes without the addition of chemical additives such as salts and polymeric flocculants. In this experimental and analytical study the authors elucidate the transport processes that control the rate of concentrated colloidal particle removal, demonstrate the process on a laboratory scale, and develop the scale-up laws needed to design comm… more

Engineering Annual Summary 1996

Description: Fiscal year 1996 has been a year of significant change for the Lawrence Livermore National Laboratory (LLNL) in general and for Engineering in particular. Among these changes, the Laboratory`s national security mission was better defined, the stockpile stewardship program objectives became crisper, LLNL`s investment in high-performance computing was re-emphasized with the procurement of a $100 million supercomputer for the Laboratory`s Accelerated Strategic Computing Initiative (ASCI) program, … more

Extensions of the longitudinal envelope equation

Description: Recently, longitudinal space charge effects have become of increased importance in a variety of dynamical situations. The CEBAF FEL injector beam dynamics shows large space-charge effects, even at 10 MeV ({gamma} {approx} 20). Space-charge dominated longitudinal motion has also been studied in the IUCF ion storage ring. Previously a longitudinal envelope equation with a self-consistent phase-space distribution has been developed, and has been of considerable use in analyzing the motion of these… more

All 56 samples have been purged with argon before storage, and the 33 samples in the DECS series are heat-sealed in foil laminate bags and stored under refrigeration. Eleven DECS samples have been collected under the current contract. The program of organic geochemical analyses for the contract was completed during the quarter, and its results (pyrolysis-GC/MS, and NMR spectroscopy by… more

Mechanisms and genetic control of interspecific crossing barriers in Lycopersicon. Final report

Description: Deficiency of Lycopersicon esculentum allele (E) was observed from the RFLP and isozyme data of the F{sub 2} populations derived from the cross L. esculentum x L. pennellii. The genome composition of the F{sub 2} populations containing L. pennellii cytoplasm (F{sub 2}{sup Lp4}) has a lower proportion of the homozygous L. pennellii (PP) genotypes and a higher proportion of heterozygote (EP) genotypes than that of the F{sub 2} populations containing L. esculentum cytoplasm (F{sub 2}{sup Le}).

Particulate Emission Abatement for Krakow Boilerhouses.

Description: Environmental clean-up and pollution control are considered the foremost national priorities in Poland. The target of this cleanup is the Polish coal industry, which supplies the fuel to generate over 78% of Poland`s primary energy production. This project addresses the problem of airborne dust and uncontrolled particulate emissions from boilerhouses, which represent a large fraction of the total in Poland. In Krakow alone, there are more than 2,000 uncontrolled boilers accounting for about hal… more

Regulation of Coal Polymer Degradation by Fungi

Description: Previous studies in our laboratory used a spectrophotometric assay to study biomimetic solubilization of leonardite by sodium oxalate. It was found, however, that in extended incubations of several days, this assay resulted in overestimation of the percent of leonardite that was solubilized. This problem did not appear to be significant for short term incubations (ie., up to -24 h) and was circumvented in long term incubations by using a gravimetric assay to assay for solubilization. In other s… more
